RGB ink-jet printing, also applied to small and medium-sized OLED?

At the “Year End Seminar of OLED/Display” held at COEX in Seoul, Korea, on December 7, Kim, Seok-Soon, CEO of Unijet said that ink-jet printing technology can implement over 550 RGB ppi and ink-jet printing can be applied to small and medium-sized OLED process as well.

The currently mass-produced QHD resolution of 5.5-inch mobile device is 550 ppi but it is actually 400 ppi with pentile structure. Moreover the ink-jet printing technology for RGB pixels is currently in the range of 150 to 200 ppi which can achieve 8K resolution on over 55inch OLED, yet inapplicable to the small and medium-sized OLED process. As Kim announced, if the ink-jet printing technology is applicable, implementing 550 ppi in the small and medium-sized OLED process, beyond QHD resolution in 5.5 inches, it is possible to implement UHD resolution in pentile structure.

<ppi by size and resolution>

Kim said, “In 2012, single droplet measurement technology showed 2.5% or less of volume accuracy, which was, however, insufficient for RGB printing.  In 2017, the laser droplet measurement technology enabled the discharge volume control less than 0.1 μm and the real-time internal pressure control reduced the volume accuracy by less than 0.1%.” Kim added that it is possible to form over 550 RGB ppi regardless of the pixel structure.

Lastly, Kim noted that the solvent purity for OLED RGB pixel is very important; “Inkjet printer can be commercialized only if ink materials are fully developed first to satisfy panel makers. He expected that it will be applied to the mass production line in earnest since 2020. ”

OLED TV with different characteristics and advantages by set makers

LG Electronics announced on last 11th that LG OLED TV is speeding up the popularization with the monthly sales volume of 10,000 units and above for the first time in Korea. In addition, Sony, which joins the OLED TV camp in 2017, is enjoying great popularity and continues to expand its market share in the premium TV market. As such, OLED TV is leading the premium TV market by improving cost competitiveness through cost reduction as well as excellent image quality.

OLED TVs are currently being mass-produced by LG Electronics, Sony, Toshiba and Panasonic. Although all set makers that produce OLED TVs use OLED of LG Display, they are producing OLED TVs with different characteristics and advantages.

First, LG Electronics mentioned OLED’s vivid image quality and wall paper design as advantages of OLED W7 which is a signature TV. LG Electronics mentioned that OLED, which is a self-luminous element, can express near-infinite contrast ratio and rich color close to nature, and supports Dolby vision HDR and HDR10 to experience vivid image quality. Also, introduced that a 4.6mm of thin panel provided the experience of seeing the theater screen and all parts except the panel were housed in a space called innovation stage and completed the perfect wall paper design.

As such, OLED TV set makers are introducing different OLED TVs that emphasize their characteristics and advantages. In addition to the above four makers, LOEWE of Germany and B & O of Denmark are expected to continue to launch OLED TVs, including mass production of OLED TVs or preparations for mass production. Based on the unique technology of set makers, it is worth noting that OLED TVs with what kind of characteristics and advantages will be produced.

Solution Process OLED, Max. 40% Decrease in Component Material Cost Possible Compared to WRGB

According to 2017 Solution Process OLED Annual Report published by UBI Research, when solution process (ink-jet printing) is applied to large area OLED, it could reduce up to 40% of component material cost, and approximately more than 18% of production cost compared to WRGB process that uses evaporation method.

 

Solution process is a technology that can manufacture RGB pixel structure of large size OLED panel without cutting mother glass using Gen8 manufacturing equipment or larger.

 

UBI Research analyst Hyunjun Jang explained that the solution process applied OLED has a simpler panel structure with 5 layers compared to 20 layers of WRGB OLED. WRGB OLED process material usage efficiency is only at 40% but solution process application could increase this to over 90%. Jang added that the lack of color filter is a factor that could decrease panel production price by reducing development cost. Particularly, this can greatly reduce emitting materials usage which occupies much of materials cost and contribute considerably to the fall in production cost. Furthermore, he added that cost setting of soluble emitting material per gram will be an important factor in production cost decrease and emphasized that organic material usage greatly decreases when soluble emitting materials are used but must consider price increase due to solvent cost, production cost, and development cost.

 

Solution process technology continues to receive attention as a key technology that can lead popularization of large area OLED, and key AMOLED panel companies are carrying out development.

 

In terms of technology, solution process OLED has lower emitting efficiency and short lifetime as diverse solvent is added to existing evaporation materials to transform into ink leading to low purity. This has been an important issue for panel and material companies for past several years. To improve this, DuPont, Merck, Sumitomo Chemical and others have been actively developing soluble OLED emitting materials. Much like evaporation materials, blue materials showed particular difficulty in performance improvement. However, at present significant portion of technology development has been carried out and investigation shows approximately 80% of lifetime and efficacy of has been achieved compared to evaporation materials.

 

2017 Solution Process OLED Annual Report compared and analysed WRGB OLED and solution process OLED’s competitiveness in terms of process, materials, and cost. Key issues, soluble OLED emitting materials development status, key companies’ trend, and solution process OLED market are analysed from various perspectives.

Is there possibility of High resolution(UHD) OLED Smart-phone generation?

Recently VR contents experience through smart-phone device has been increased, therefore high resolution of smart phone is becoming necessary. However, OLED smart-phone resolution still remains at QHD level for 3 years since QHD OLED is applied to Galaxy Note 4 for the first time in 2014.

The core point that decides resolution of OLED smart-phone is evaporation process for emission layer. Bottom-up type evaporation method, which is applied to the recent devices is that substrate and FMM (fine metal mask) are horizontally arranged on the upper side of evaporator and vaporize the organic material from the lower linear source in order to form RGB layer.

Thin FMM measures less than 15um thick is necessary for making high resolution OLED like UHD level, however, as FMM gets thinner, it would be difficult to make mass production because technical problems will be occurred such as patterning, sealing and welding.

In order to solve these problems, various metal mask patterning technologies are being developed such as vertical type evaporation and plane source evaporation.

Vertical type evaporator that arranges board and FMM vertical is developed by Hitachi of Japan for the first time. And Canon Tokki exhibited Gen6 vertical type evaporator at Finetech Japan 2013, however it is not being used for mass production at the moment.

<Canon Tokki’s Gen6 vertical type evaporator which is exhibited at Finetech Japan 2013>

According to the recent ETNEWS, Applied Materials developed Gen6 flexible OLED vertical type evaporator and it is being tested in Japan Display.

Plane source evaporator is being tested but also the linear source type. Plane source evaporator method is that an organic material is first evaporated on the metal surface to produce plane source, then re-evaporated in order to form an organic thin film on the substrate.

In the past iMiD 2017, representative of OLEDON, Chang Hoon Hwang mentioned that 2250 ppi resolution OLED can be implemented through plane source evaporator.

For metal mask patterning technology, electro forming and laser patterning technology is highlighted. Electro forming method is developed by Wave Electronics, TGO Technology, Athene and so on. Laser patterning technology is being developed by AP Systems.

As such, development for high resolution OLED is receiving great attention whether it can solve the current problems and contribute to UHD resolution implementation for OLED smart-phone.

LG Electronics, Big step on popularization of OLED TV

<OLED TV of LG Electronics Source: LG Electronics>

LG Electronics OLED TV is speeding up its popularization with exceeding monthly sales of 10,000 units for the first time in Korea.

‘LG OLED TV’ was sold every four minutes last month. Compared to the beginning of this year, it’s double. LG Electronics expects sales increase of OLED TVs in the future and to rapidly increase market power.

The secret to increasing sales is recognition of outstanding image quality. LG OLED TV, this year, was first in the performance evaluation conducted by nonprofit consumer magazines in 11 advanced markets including the US, UK, Germany, France, Italy, Spain, the Netherlands, Sweden, Belgium, Portugal and Australia. Unlike LCD TVs, the contrast ratio is high because it emits light without backlight. So it presents perfect black and realizes a lively screen.

Consumers consider picture quality the most when purchasing TV. According to a consumer survey conducted by LG Electronics, over 40% of the respondents cited image quality as the top priority when purchasing TVs. This percentage is the highest of all purchasing considerations.

Reasonable price is also the cause of good sales. LG Electronics has continuously developed technology for more consumer to experience OLED TV image quality so as to reduce the. 55-inch OLED TV prices have fallen to the mid-2 million won. It is no different from premium LCD TVs. In 2013 when LG Electronics first launched OLED TV, it was worth 15 million won.

‘LG OLED TV’ accounted for about 30% of LG Electronics domestic TV sales this year and settled perfectly in the market.

Son, Dae-Gi, LG Electronics Korea HE Marketing FD, emphasized “we will expand sales to allow more customers to enjoy ‘LG OLED TV’ image quality and have a solid profit structure by raising premium market power”.

According to UBi Research, the AR/VR market will expand full scale in 2019, when 5G is introduced, which can mass-produce UHD contents and transfer large volumes of content fast and the total revenues of virtual reality and augmented reality products will reach $ 58.7 billion by 2021.

Cynora, TADF will contribute to high-resolution implementation of OLED devices and panel cost reduction

At the Global Materials Tech Fair 2017 held on September 22 in COEX, CEO Ko Chang-hoon of EM Index, Cynora’s Korean partner, announced the development of the thermally activated delayed fluorescence, blue TADF, which is currently under development at Cynora.

<CEO Ko Chang-hoon of EM Index>

Generally, the blue light emitting material is insufficient in life and efficiency compared to red and green. For this reason, OLED panels for mobile devices are manufactured relatively large in blue pixel size compared to other pixels, in the OLED panel for TV, blue light emitting layers are laminated twice. The blue TADF is the material that is being developed to overcome the limitations of this blue light emitting material.

CEO Ko Chang-hoon mentioned “Applying blue TADF increases lifetime and efficiency, so it does not need to increase pixel size and it is advantageous for high resolution implementation” and emphasized “In mobile devices, it will be advantageous to reduce power consumption as well as realize high resolution and in case of TV, it will be advantageous to reduce the panel cost because only one layer of blue light emitting layer needs to be formed.”

He referred to the recent investments of € 25 million from Samsung Venture Investment and LG Display and explained that it was a proof that blue TADF is attracting a lot of attention.

It is also close to the efficiency, lifetime and color purity of the blue TADF required by major OLED panel makers and is expected to meet these requirements by the end of 2017.

<Cynora’s blue TADF development progress>

Finally, the company announced the development roadmap for the green TADF by the end of 2018 and the red TADF by the end of 2019, and concluded by emphasizing that TADF would contribute to high-resolution implementation of OLED products and panel cost reduction.

Fraunhofer Institute will introduce automotive flexible OLED lighting at ISAL 2017

Specialized in development and manufacturing OLED module, Fraunhofer Institute will introduce Automotive flexible OLED lighting with adjusted color at ISAL 2017 which will be held in Darmstadt, Germany from 25th to 27th September. Fraunhofer Institute had released previously OLED which the color can be adjusted by rigid substrate in 2015.

Fraunhofer Institute has continued to develop flexible OLED lighting since then. Flexible OLED lighting which will be shown at ISAL 2017 is known to be changed to yellow and blue color. It can be shown as white light by making of yellow and blue color at the same time.

Fraunhofer Institute predicts that flexible OLED lighting will be replaced for car interior lights and it could also be used on the ceiling or winding parts where lights cannot be built easily. Commercial lighting is required to have heatsink and unfortunately it can not be easily built with lack of flexibility in design. However flexible OLED lighting is very light and thin which means it is expected to be widely used for Automotives interior with its flexible design. Fraunhofer Institute also made a comment that they may produce flexible OLED substrate glass, metal and plastic film as well.

OLED lighting has been recently used for Automotives interior and it is expected to be used more in the next generation. Customized Automotive service company, Changscustom showed OLED lighting built in the car at Seoul Auto 2016. Furthermore lighting companies including LG Display and Osram supplied OLED tail light with Mercedes-Benz and BMW.

Meanwhile, according to 2017 OLED Lighting Annual Report which was recently published by UBi Research, using of Automotive OLED Lighting will be increased to $2.11 billion in 2025 from $6.4 million in 2017 with 107% of growth rate. Especially flexible OLED Lighting is expected to capture a higher market share more than 95% and flexible OLED Lighting will be widely used instead of rigid OLED lighting.

Starting to have mass production process in Gen5 OLED of LG Display from end of September, lighting market is expected to reach full growth. The growth of OLED lighting market is being watched with keen interest to compare with strong growth of OLED display market.

UBi Research, Lee Choong-Hoon, CEO, announce OLED market and forecast

Mr. Choong-Hoon Lee, the CEO of UBi Research, OLED specialist presented the market trend and prospects of the OLED industry following last year at the Japan Conference, host by Merrill Lynch Japan Securities, from 5th to 7th of September in Tokyo, Japan. The annual conference was held for Merrill Lynch Securities customers, consisting of a forum-type presentation on major industry trends in Japan and small meetings with presenters.

The fact that Mr. Lee, the CEO of UBi Research was invited to the event indicates the importance of the display market, not just in the IT industry but also in the global market industry. Among investors in recent years, display is in the spotlight at as an emerging industry and participants have shown their interest in the latest OLED technology trend as well as current and future production scale of OLED panel manufacturers.

Mr. Lee was also had an interview with Nikkei Business Publication regarding “Global OLED Market Trend and Forecast” during the conference. The main interview question is focused on “OLED industry trend and future OLED TV market development”. According to Naoki Tanaka, editor of Ronny Keikyo Newspaper, Japanese electronics industry is expecting to revive the old glory of display industry, showing its interest in the OLED industry and OLED TV.

In the interview, Mr. Lee stressed, referring to the market data in the UBi Research OLED display report, that Japanese display manufacturers who still believe perpetuation of LCD need more reliable OLED market analysis.

In addition, he said that through the exhibition trend of OLED TV at 2017 IFA held in Berlin, Germany it is worthwhile paying continuous attention to the premium OLED TV market in the future. At the end of the interview, he emphasized how important OLED production by Japanese panel manufacturers would be to Japan’s entire display and set industry.

UBI research publishes 2017 OLED lighting report : LG Display, ready to mass-produce OLED light panel, expecting OLED lighting market to grow fast

LG Display starts mass production of 5G OLED panel for lighting from the end of September

■ OLED lighting panel market is projected to grow from US$ 1.9billion in 2021 to US$ 5.8billion by 2025

 

LG Display will start mass production of 5G OLED light panels from the end of September, therefore attention is focused on whether the OLED lighting market is growing rapidly. According to LG Display, monthly production capacity is 15K, and it is to be increased to 90K later.

 

According to the ‘2017 OLED Lighting Annual Report’ published by UBI Research on August 8, the global OLED lighting panel market is expected to grow to about US$ 1.9 billion by 2021. Furthermore, it is projected to have a CAGR of 85% for the period 2017-2025, and form a market of US$ 5.8 billion in 2025.

Because OLED lighting is thin, light and flexible, it does not limit the installation space and has excellent design autonomy. In addition, OLED lighting is used for automotive, exhibition, and medical as well as general indoor lighting because it can create a comfortable atmosphere with little heat and flicker.

 

However, the market for OLED lighting has been slower than that of OLED display, which is widely applied to mobile devices and TVs. Osram focuses primarily on automotive OLED lighting, and Philips sold its OLED lighting division to OLEDWorks. Also, Japanese panel makers such as Sumitomo Chemical and Konica Minolta have developed OLED lighting for industrial and medical applications. Nevertheless, it seems to take time for OLED lighting to become eventually a large market.

With LG Display’s mass production of Gen5 OLED line, the price of OLED light panel is estimated to drop below US $ 10 (100 x 100 mm). The significant price competiveness might enable OLED panels to be applied to various areas such as automobile and display lighting as well as indoor lighting. Owing to this expectation, attention is focused on whether the OLED lighting market, showing signs of slow growth, can be materialized.

UBI Research predicted that LG Display would account for about 70% of the world’s lighting OLED panel market in 2017, and will continue to lead the OLED lighting panel market with a 50% market share in 2020.

 

Meanwhile, ‘2017 OLED Lighting Annual Report’ describes trends of next-generation lighting market, promising applications, cost analysis upon the investment of LG Display and forecast of OLED lighting market. Since it analyses particularly OLED lighting market, materials market, and equipment market forecasts for OLED lighting from various perspectives, it is expected to help the related companies identify the OLED lighting market.

Material Science to develop blue dopant for OLED … OLED Efficiency ⋅ Lifetime Up↑

A Korean venture company has succeeded in developing blue dopant for Organic Light Emitting Diodes (OLED) that a Japanese company has had its exclusive patent for. The dopant is an element that improves efficiency and life time by mixing with host that actually colors within the OLED.

In the meantime, many domestic material companies have developed OLED host, but it is the first case that a venture company has independently developed dopant on a commercial scale without receiving any support of large corporations.

 

Material Science (CEO Lee Soon-chang), an organic material developer for OLED has developed a technology that can replace Japanese I Company’s patent for blue dopant. Established in 2014, Material Science is supplying HTL( Hole Transporting Layer) and ETL (Electron Transfer Layer) to OLED panel makers.
Half of the 50 employees are R&D personnel. Last year, its sales were 6.6 billion won, and it is expected to exceed 10 billion won this year.

This time, due to the development of blue dopant by Material Science, OLED panel companies have an alternative to supply blue host and dopant besides I Company.

Japanese I Company has been developing blue dopant since 1995. At present, the company has more than 30 patents related to blue dopant (based on Japanese application for a patent), and its major 8 patents are valid until 2034. In particular, it has an exclusive patent for the combination method of blue dopant that includes blue host and pyrene with an anthracene structure (a compound in which three benzene rings are sequentially bonded). For this reason, the panel makers which purchase dopant from I Company must buy its host. If they mix I Company’s blue dopant with another company’s host, it is inevitable to infringe the patent in the case a host material has an anthracene skeleton.

Both Samsung Display and LG Display have been using I Company’s blue dopant and host.

The blue dopant developed by Material Science is designed to make molecules that are completely out of I Company’s compound patent. Conventionally, the method of applying an electron acceptor to a molecule has been used to improve the efficiency and lifetime of OLED and have a blue color.
On the other hand, Material Science introduces electron donor into molecules to improve the efficiency and lifetime while generating dark blue color. This dopant greatly reduces the solvent-dependent color development (solvatochromism) where emission wavelength changes due to the polarity of the surroundings. Therefore, the change of emission wavelength is also greatly reduced.

Jung Jae-ho, a researcher at Material Science said, “We have developed a new structure and a synthesis method, which makes it possible to produce its differentiated dopant.” “Panel companies are now able to utilize various types of blue hosts”. In addition, Material Sciences has been recently developing TADF(Thermally Activated Delayed Fluorescence) that OLED panel makers are struggling to introduce for the longer life of blue-emitting phosphors.

<OLED emitting material market forecast, UBi Research>

According to UBi Research, the OLED organic market is expected to reach $ 3.36 billion by 2021 (about 3.8 trillion won). And blue materials account for 11.5% of total sales.

[iMiD 2017] Samsung Display, Huge release of application using OLED

A company official said “The higher the ppi, the better the experience of realism and immersion,” and mentioned “We are currently developing higher resolution OLEDs.”

<Comparison of 3.5 inch 460 ppi OLED and 3.2 inch 806 ppi>

In addition, Samsung Display exhibited OLED light field displays in the future display zone, and in the AMOLED zone, visitors can directly compare LCD and OLED.

A company official explained that “light field display is a technology that implements 3D by applying an optical lens on a panel, which is a little different from hologram using light interference effect.” And he said “We are developing a viewing angle that is wider than 30 °,” revealed “We now have pixel and lens alignment issues and optical design issues.”

<OLED light field display description and specification>

In the AMOLED zone, panels were displayed to directly compare the contrast ratio of LCD and OLED. The contrast ratio and color expressiveness of the OLEDs were clearly different from those of the LCDs, and a company official said, “These differences are the reasons why OLEDs are used in the Galaxy series.”

<Comparison of OLED (Left) and LCD (right) image quality>

Samsung Display has also introduced 1.3 inch circle OLED and 12 inch FHD OLED, which led to the great interest of the visitors during the exhibition.

[iMiD 2017] LG Display, Spur Development of 77 inch transparent flexible OLED

LG Display’s Kwon Se-Yeol senior researcher introduced the 77-inch transparent flexible OLED which had been introduced in June at IMID 2017 held in BEXCO, Busan on Aug. 30, and announced the applied technologies to realize this.

Kwon Se-Yeol senior researcher mentioned, “OLED is self-luminous, so it can be manufactured with a thin thickness because it does not need a back light unit. The thinner the thickness, the more flexible the OLED can be so that it is easy to implement flexible displays with OLEDs.” and forecasted. “It can be used in various fields such as signage and smart desk.”

The 77-inch transparent flexible OLED which is released this time is a top emission type for improved luminance. The transparent thin film encapsulation layer is applied, different from the conventional OLED TV or large flexible OLED, and two polyimide substrates are used.

Kwon Se-Yeol senior researcher said “We applied a transparent thin-film encapsulation layer instead of the existing metal encapsulation layer for the top emission method ” and explained “A white OLED light emitting layer and a color filter layer were formed on two polyimide substrates and cemented together. A barrier film and a multi-barrier were applied to the top and bottom of the polyimide substrates to prevent moisture and oxygen penetration.”

The Kwon Se-Yeol senior researcher then states that “flexural rigidity of the panel is mainly affected by the thickness of the polarizer and the encapsulant layer, so it is necessary to reduce the thickness in order to improve the flexibility”, and emphasized “By reducing the thickness of the encapsulant layer from 100 μm to 20 μm, we can reduce the strain on the OLED module from 0.36% to 0.21%, along with improved flexibility”.

In addition, he mentioned that surface reflection due to polyimide birefringence phenomenon, laser wavelength selection according to polyimide properties in LLO (laser lift off) process, and use of flexible OLED module are all covered, and technical development is continuing.

Meanwhile, LG Display has developed the world’s first 77-inch transparent flexible OLED with UHD (3840 × 2160) resolution, transmittance of 40%, and radius of curvature of 80R as part of the national project.

[iMiD 2017] OLEDON, Disclose plane source FMM deposition principle for 2250ppi OLED manufacturing

Prof. Hwang Chang-Hoon, CEO of OLEDON, a venture laboratory of Dankook University, presented a plane source FMM deposition technology capable of implementing 2250 ppi at iMiD 2017 held on the 28th.

According to Prof. Hwang Chang-Hoon’s presentation, the plane source deposition technology developed by OLEDON differs from the existing organic material deposition method. The plane source FMM deposition technique is that the organic material is first deposited on the metal surface to form a donor film and then re-evaporate it to form an organic thin film on the substrate. Applying this technique, organic matter forms a vertical gas beam due to plane evaporation. (Source patent: 1012061620000 Republic of Korea)

The shadow distance when organics are deposited with a plane source developed by OLEDON is 0.38 μm – 0.59 μm. This is a level at which a 2250ppi device having a pattern size of 4 um can be manufactured.

Prof. Hwang Chang-Hoon explained ‘applying the plane source deposition technique reduces the incidence angle of the organic material and dramatically reduces the shadow caused by the mask’. In addition, ‘using a plane source, the perpendicular organic gas beam can form a completely zero incident angle, so theoretically, the shadow distance can be zero um’.

<Principle of plane source deposition technology developed by OLEDON>

In addition, Prof. Hwang Chang-Hoon emphasized that ‘plane source deposition technology is essential for high-resolution shadow masks’.

For linear source FMMs currently in production, the shadow mask opening distance is 80 μm. As a result, the incidence angle of the organic material gas is inevitably large, making it difficult to produce a shadow mask having a high density pattern.

Prof. Hwang Chang-Hoon explained, ‘Using plane source deposition technology, shadow mask taping angle is 80 ° level’, and the distance between openings can be reduced to less than 20 μm so that plane source deposition techniques can solve the mask pattern density problems of linear sources’.

OLEDON is challenging fully shadow-free patterning conditions with plane source deposition technology, and plan to develop and install a plane source FMM evaporator capable of manufacturing 11K class micro OLED devices in cooperation with Prof. Jin Byung-Doo in Dankook University.

<The opening density change of the shadow mask when the plane source FMM deposition technique is used>

Meanwhile, OLEDON has 13 registered patents for plane source FMM deposition for mass production. Based on recent research results, they filed 7 new patents for mass production equipment in Korea and 3 applications are filed for PCT international application.

[iMiD 2017] AP Systems, Find FMM answers through USPL

At iMiD 2017 in BEXCO, Busan on 28th, AP Systems announced that it succeeded in developing 1000ppi FMM with USPL (ultra-short pulse laser).

Since FMM plays a role of depositing pixels and RGB organic materials, FMM serves as a factor that determines resolution and yield of OLED. At present, FMM is mainly manufactured by etching method. This method has a problem that a shadow phenomenon due to the precision, thickness, and weight of the fine pattern occurs, in order to solve this problem, various FMM manufacturing processes such as laser processing and electro-forming have been developed.

Among these, laser processing method has an issue of forming burrs around pin-holes due to the thermal effect caused by laser irradiation. These burrs increase the shadow interval of the FMM, which causes overlapping of patterns during RGB organic deposition, thereby degrading the resolution of the OLED.

AP Systems has developed a burr-free laser process that does not have burr phenomenon and further controls the taper angle.

The Burr-free laser process is a short-time irradiation of unidirectional pulses at a constant number of times, since the laser is not continuously irradiated, it minimizes accumulated heat energy and prevents burr formation. In addition, by controlling energy of the laser, it accumulates energy and forms taper.

In this way, AP Systems explained ‘they produced FMM with various shapes of fine pin-holes such as square, diamond, and polygonal shapes, as well as 1170ppi FMM’, and ‘’We also developed large-area FMM manufacturing equipment with USPL method’.

AP Systems also added ‘multi-beam and USPL is equipped for FMM manufacturing equipment so that it can improve productivity and realize UHD’.

Since the launch of the Galaxy Note4 in 2014, the OLED resolution has remained at the QHD level yet. In order to manufacture an OLED having a high resolution (UHD level or higher), it is necessary to solve various technical problems faced by FMM. Accordingly, it is noteworthy how USPL technology of AP Systems will affect the future OLED market.

[iMiD 2017] TCL, Development focusing on Solution process OLED and QLED

TCL’s Xiaolin Yan CTO addressed solution process OLED TV and self-emitting QLED TV as premium TV after white OLED TV at iMiD 2017 keynote address in BEXCO, Busan on 29th.

Yan CTO noted that white OLED TV, which is currently leading the premium TV market, meets all the requirements of premium TV due to its superior image quality, design differentiation, high resolution realization and nature-friendly characteristics compared to QD LCD TV.

In addition, the price that is higher than the current QD LCD TV is expected to be overcome by applying the solution process, and mass production is also expected in 2019.

Yan CTO predicted that the “solution process would be easy to produce 75-inch panels at Gen 10.5 because the process can be performed without splitting the ledger,” and “it is also possible to produce full-emission RGB OLED TVs.” However, he emphasized that the compatibility of materials and equipment and the development of ink forming process technology should be done.

Following to that, “QLED structure is very similar to OLED structure, so it is easy to apply the technology because of the low entry barriers,” he said. “The lifetime and efficiency of the blue light emitting layer compared to the current OLED is very low, and performance must be ensured without the use of cadmium.”

Lastly, He mentioned the establishment of printing technology in Guangdong JUHUA to promote the commercialization of solution process OLED TV and self-luminous QLED TV, and emphasized the cooperation of material, equipment and panel makers to develop next-generation premium TV.

We have been receiving many enquiries for flexible display from the market, specifically, wearable devices, smart home appliances, electric cars and self-driving cars etc. This is a pretty exciting display technology and we do believe there is a considerable potential market size.”

OLED Encapsulation, TFE is the Top Trend

  • Expected application of TFE to all edge type and full screen use flexible OLED
  • PECVD manufacturing equipment, 62% of total encapsulation manufacturing equipment market

According to 2017 OLED Encapsulation Annual Report published by UBI Research, of OLED encapsulation technology, TFE (thin film encapsulation) will be applied to approximately 70% of total OLED panel in 2021, and become the key encapsulation technology.

OLED display trend is heading toward minimizing bezel for full screen actualization from edge type, and flexible OLED is being considered as the most optimal display for full screen. As such, Chinese panel companies, as well as Samsung Display and LG Display, are concentrating on flexible OLED mass production line investment rather than rigid.

Flexible OLED must be thin and bendable; glass using frit encapsulation Is not suitable and TFE (thin film encapsulation) or hybrid encapsulation must be applied. TFE is a structure that is formed via laminating thin inorganic and organic materials. In the early stages of development, it had 11 layers of complex organic and inorganic material deposition with low yield. However, it now has been reduced to 3 layers and greatly improved productivity, yield, and cost and it is being applied to most of flexible OLED.

<Thin film encapsulation development history, 2017 OLED Encapsulation Annual Report>

Hybrid encapsulation, which uses barrier film, is being applied to some flexible OLED. However, due to the high cost of barrier film and relatively thick thickness, recent investment is focused on TFE application.

According to UBI Research analyst Jang Hyunjun, TFE encapsulation is expected to continue to be applied to edge type and full screen type flexible OLED panel, and related manufacturing equipment and material market will carry on their growth.

The report explains that TFE’s key manufacturing equipment are inorganic material forming PECVD and organic material forming ink-jet printer. In particular, PECVD is used in inorganic material film formation of hybrid encapsulation as well as TFE. Therefore, PECVD market is estimated to record US$ 6,820 million in 2017-2021, and occupy approximately 62% of the total encapsulation manufacturing equipment market.

<PECVD manufacturing equipment market volume, 2017, 2017 OLED Encapsulation Annual Report>

The report includes encapsulation related key manufacturing equipment and material market in addition to encapsulation development history and trend, and key panel companies’ trend.

The performance in Q2 for HE area of LG Electronics showed 4 trillion and 234.9 billion won in sales, and 343 billion won in operating profit. The QOQ on sales was declined to 2.1%, and the demands of the global TV market are continuously reducing, but the sales of the same quarter in last year showed 1.9% growth through the sales expansion of the OLED premium TVs.

Jin-ho, Ha, the HE director of LG Electronics said that “The Q2 performance was slightly decreased in QOQ and same quarter in last year due to the panel cost increase and marketing promotion for the new product launching, but we sustained healthy profit structures through the expansion of the premium TV sales and the improvement of cost structures consistently.” And also expected, “There are concerns on the slowdown in growth of worldwide TV market for the interest rate hikes and the oil price decrease, nevertheless, the premium TV market will steadily grow according to the demand increase on OLED TV and UHD TV.”

Subsequently, he answered on the question of the counterstrategy for the SONY, “It is not just right time to judge the OLED TV of SONY yet, but until now, we think that the OLED TV of us is quite superior regarding the aspect of design of products, image quality, and its lineup and so on.”

On the recent investment for large-sized OLED of LG Display, “LG Display and LG Electronics, both of us, will wisely take and proceed the world best strategy together of premium TVs by strengthening the premium status of OLED TV.”

He explained on the TV business of LG Electronics, “We have been improving the profitability focusing on the premium lines, and also completely avoiding the quantitative competition. We plan to continuously sustain the quality-oriented rather than quantity.” He added, “We will pursue the activities to intensively keep the premium image of OLED.”

They stated to be maintaining the stable profit structures with aiming at continuous sales expansion of premium products through the marketing promotion for the premium TV-oriented to prepare the high-season for the TV market in second half.

Samsung Electronics’ Display Business Recorded Operating Profit of 1.71 Trillion KRW in Q2, 2017

Samsung Electronics announced that it reached sales of 61 trillion Korean won and operating profit of 14.07 trillion Korean won, and the display business recorded 7.71 trillion won and operating profit of 1.71 trillion won, through the Q2 2017 Earnings Conference Call on 27th. Its display business has recorded more than 1 trillion won in the black, for 4 consecutive quarters since Q3 2016.

 

According to Samsung Electronics, its earnings for Q2 2017 has increased compared to the previous quarter due to the expanded sales of flexible OLED panels and high value-added LCD products.

 

The OLED division saw its earnings improvement on the back of flexible products sales increase due to the expanded sales of major customer flagship models, and accounted for low 60% of sales. The LCD division also improved earnings by expanding the sales of high value-added products, mainly UHD and large TVs.

 

The OLED division is expected to see sales growth for the second quarter of this year due to the expanded supply of flexible products compared to the last quarter. However, there will be fiercer competition with LTPS LCD in the mid to low-end market and a risk of cost increase resulting from ramp-up of new capacity lines. Accordingly, Samsung plans to improve profitability by aggressively responding to major customer demand through stable ramp-up of new lines and improving product mix.

 

The LCD division is anticipated to be in a supply-demand imbalance due to set companies’ stock increase of panels and panel suppliers’ supply expansion, but premium TVs such as high resolution and super-size TVs are expected to continue to grow. Samsung has a plan to increase profitability by promoting yield and cost improvement activities and by expanding the sales of not only high value-added products such as UHD and large-size products but also differentiated design products such as frameless and curved products.

 

Samsung Electronics recorded sales of 93 million mobile phones and 6 million tablets in Q2 2017, and in the third quarter, the sales of mobile phones and tables are likely to increase slightly and remain flat, respectively quarter on quarter. The sales volume of LCD TVs is expected to reach 9 million units and grow at low single in the third quarter.

 

Samsung Electronics invested a total of 12.7 trillion KRW in its facilities in the second quarter, of which 4.5 trillion KRW were invested in the display. This year’s investment plan for facilities is yet to be determined, but investment is expected to increase substantially from last year, especially for semiconductors and displays. The display division plans to invest in production expansion to meet the increasing demand for flexible OLEDs.

 

Director Lee Chang-hoon of Samsung Display said, “The smartphone set makers’ OLED adoption will continue to increase with the constant strong demand for it. The current OLED line is being resiliently operated in line with market and customer needs”. He added “We will continue to use and operate OLED lines strategically in accordance with market demand and customer needs.”, and explained they are not considering the plan to further shift LCD lines into OLED.

LG Display, Expects 40% of OLED out of total sales in 2020.

LG Display spoke that they plan to change the sales structure by focusing on the OLED sales at the conference call in Q2, 2017 which was held on 26 July, and they expected that the OLED sales portion among the total sales would be from 10% in this year to 40% in 2020.

Sang-don, Kim, the CFO of LG Display said that they will invest about 15 trillion won of production line for the Gen10.5 OLED and the Gen6 POLED(Plastic OLED) at Paju P10 factory against 4 years. He said that “The investment of Paju P10 is a leading task for the mass production and the improvement of efficiency because the demand of OLED TV is rapidly increasing by the forecasting of 2.5 million units in 2018 and 6 million units in 2020. We will take the P10 factory as an OLED hub.”

The CFO also said that “We plan to order and install the necessary equipment from July 2017 to January 2019 for the Gen10.5 OLED line in Paju P10 factory, and through test period for 6~12 months, the 1st target will be to mass-produce the OLED of 30,000 units per month based on single unit. 5 trillion won will be invested to the P10 factory to install new lines of the Gen6 POLED with 30,000 units per month and it would be started to produce it in 2019.”

Accordingly, LG Display announced that E5 in Gumi, which was previously invested, plans to mass-produce the Gen6 POLED with monthly 15,000 units of scale in this year, E6 in Paju plans to mass-produce the Gen6 POLED with monthly 15,000 units of scale in Q2 2018. In addition, they mentioned that at the OLED new line in Guangzhou, China, will mass-produce the Gen8.5 OLED with monthly 60,000 units of scale from the first half of 2019 by the investment of the 5 trillion won. For concerns on the technology leakages about the investment of the Gen8.5 OLED in Guangzhou, the CFO, Sang-don, Kim, said “There was no cases of technology leakages in the LCD line of Guangzhou until now from last 2013 since the OLED is complicated technology to copy, and there would be much benefit by the localized equipment and all investment instead of it.”

Meanwhile, the sales of LG Display for the Q2 this year were reduced QOQ 6% (7,620 billion won) as 6,629 billion won, but, increased 13% versus same quarter of last year (5,855 billion won). The portions by the products are following: 46% for TV panels (QOQ +3%p), 22% for Mobile panels (QOQ -4%p), 17% for Monitor panels (QOQ +2%p), 15% for Laptop/Tablet panels (QOQ -1%p). LG Display explained that the performance in first half declined due to the seasonality impact, but the shipments in second half considered as high-season, will be increased versus first half.

What is the next-generation display poised to outshine OLED?

The micro LED, QLED and hologram, which are referred to as the next generation displays, were presented at the seminar entitled ‘Recent Trends in Display and Vehicle Display Technology’ hosted by UBI Research on the 14th.

Under the theme ‘Technical Issues of micro LED Display and Market Trend’, professor Moon Dae-gyu of Soonchunhyang University said, “Micro LED can be realized in high resolution and it is easy to implement curved display or flexible display because there is no limit of panel shape and size” He added “When applying micro LED to a display, high resolution is feasible even on a small substrate size, so that it can be applied to VR, etc.” and expected “When applied to a public display, it will be able to escape from the method of tiling many display panels”. However, there remain some technical problems such as the problem of transferring and connecting millions of LED chips quickly and accurately, the deviation problem of color and luminous efficiency between LED chips, and the technical problem of implementing an active matrix for the application of a display.

<Professor Moon Dae-gyu of Soonchunhyang University>

Next, Dr. Hwang Do-Kyung of Korea Institute of Science and Technology(KIST), Dr. Bae Wan-ki, senior researcher of KIST, and Dr. Oh Min-Suk of Korea Electronics Technology Institute(KETI) announced the manufacturing principle of quantum dot and the possibility of self-emitting QLED using it. Dr. Hwang said, “The quantum dot has the advantage of not only color change depending on the size and but also narrow half width.” “Self-emitting QLED can display higher color purity than OLED.” he added.

Dr. Bae expected “If research is carried out on an enterprise scale, the speed of technology development will increase more rapidly.” saying that “At present, the efficiency of quantum dot devices is continuously improving, but the life span is insufficient compared to OLED.”

“We need the next generation display technology to follow the LCD and OLED,” said Dr. Oh Min-Seok of Korea Electronics Technology Institute(KETI). He added “QLED is attracting much attention as a next-generation display, but there remain such issues as too much focus on the development of emitting devices, the lack of solution process-related devices and technologies, and the non-cadmium-based high-efficiency blue light emitting devices”.

<Dr. Oh Min-Seok of Korea Electronics Technology Institute(KETI)>

As the last speaker, Kang, Hoon-Jong, team leader of Korea Electronics Technology Institute(KETI) explained the digital hologram technology and its application, and emphasized that a display panel capable of expressing the hologram is necessary to implement it. He said “We have a holographic printer or a microscope but there is no enough technology to apply it to TV”. Then, he closed his presentation saying “We need to develop a film for hologram first and then a functional design that can implement the screen.”

During the presentation about the next generation display, many of the speakers emphasized the importance of cooperation and participation among schools, research institutes and companies in order to overcome technical problems and realize them as actual displays. The display competition is expected to become even more intense in the future, as R&D in micro OLED, QLED, and hologram, which are considered as the next generation display, is concentrated.

The OLED is the best automotive display

The seminar on the trend of the up-to-date technology for the next generation display which was themed ‘The technology trend for latest display and the automotive display’ hosted by the UBI Research, was held on July 14th at COEX in Seoul.

In the seminar, Sun-hong, Park, a senior researcher of automotive parts, said that “The attention to the display is increasing due to the importance of the visual intelligence, and its application will also grow because the OLED is able to easily realize the flexible deign and the transparent display.”

In addition, he expected that “The digitalization for the automotive will be lasting, and the China will take 50% and more of the worldwide consumption market for automotive in 2020, and the application of display including OLED will increase in accordance with the attributes of the Chinese who prefer colorful design.”

During the briefing of a car not having a side mirror which became an issue in recent, “The application of the OLED which has rapid response speed and wide viewing angle is highly likely to be employed. If it can just overcome the reliability, the OLED will be the best display for the automotive.”

In the other side, according to the “Automotive Display Report – application & market trend analysis and the market forecast” published by the UBI Research, it expected the OLED panel will be started in earnest applying to the cluster or CID of the automotive from 2018, and the automotive display is expected to grow about 17% annually, reaching around US$ 25,000 million by 2022. The AMOLED panel market among this will be account for about 20%.

Reduce OLED manufacturing time to 1/10

Manufacturing technology has been developed to quickly fabricate OLED.
The Korea Research Foundation (KFRI) announced the Yun, Hongseok research team at Hanbat National University has developed a high-speed transfer technology that can effectively transfer multiple thin OLED layers to desired locations through high-pressure air jet injection.

The OLED transfer separates multiple layers of thin film from the substrate all at once and combines them with other thin films to produce a device. At this time, the thin film is ripped apart or wrinkled, and the corner is torn off, which make it difficult to mass-produce.

<A conceptual diagram of energy transfer process of polymer OLED multilayer thin film using air jet, Source: Korea Research Foundation>

The team used the principle of effectively controlling the bonding energy between the thin film and substrate by a high-speed peeling technique using the air jet technology,. An air jet close to the sonic speed is injected between the substrate and OLED thin film to effectively reduce the bonding force with the substrate, thereby enabling the transfer without damaging the thin film. The high-speed transfer method through the air jet requires only short time to transfer the OLED; the processing time takes about 1/10 of production time. OLED thin films can be manufactured at low cost by coating them with a solution.

Professor Yoon, Hongseok explained, “This research has developed a technology that can rapidly manufacture OLED device because they can be effectively transferred all at once by using an air jet without damaging the OLED thin film. The unit production cost of OLED can be significantly reduced, which has been used in a wide range of applications such as OLED lighting, advertising and display. It is expected to be applied to basic electronic devices in the future such as solar cells and semiconductor devices. ”

The research was carried out with the support of the Researcher Support Project for the Basic Research Support Program of the Korea Research Foundation and was published in the international journal on nanomaterials applications, Nanoscale.

OLED TV is the competitive TV covering the whole areas such as the design and the sound quality as well as the image quality.

“While the existing OLED TV is focused on the image quality, the current OLED TV is not only picture quality but also covering any areas including the design and the sound quality.”

In the keynote address for the workshop of ‘the 12th Display National R&D Projects’ held on 5 July in Hoengseong, Gangwon-do, Soo-young, Yoon, a director of LG Display, introduced the advantages of OLED TV such as superior image quality, design freedom, and sound quality improvement including the capacity of the light and shade, and color implementation.

He said, “It is unlike LCD, OLED is the self-emitting, and be able to be controlled by a pixel unit, so that it is capable of expressing the perfect black, and implementing the unlimited contrast range. Therefore, OLED is the best display to express the stars or a bright moon in the darkness.” And also, he emphasized that “OLED TV is free to express the middle gradation through the precise color expressiveness, so that it is able to realize the vivid color as realistic.”

 

Subsequently, he introduced the wallpaper and CSO (crystal sound OLED) which attracted lots of attention in last CES 2017, “If the existing OLED TV is an image quality-oriented, the current OLED TV goes through any areas such as the design, sound quality but also the image quality. Especially, the embedded speaker methods are able to realize the high level of immersion, by agreeing the position of the mouth and the sound along with the effect of design advancement.”

A director, Soo-young, Yoon, also introduced the transparent flexible OLED which can implements the radius of curvature 80R, 40% penetration ratio, and 77-inch UHD, that developed for the commercialization, and mentioned that the transparent and flexible display will be a future display. He also said that they are on-going to develop the devices and materials for solution process, and it needs to be discovered the new application and new form factor.

Finally, he mentioned the P10 factory at Paju, “We expect to ultimately produce new OLED TV at P10 factory which plans to be completed by the end of this year through thorough preparation.”

OLED Highly Polarized OLED, A New Approach to Improve OLED Light Efficiency,

Professor Kim Jae-Hoon of Hanyang University announced at the seminar, ‘OLED market analysis and latest technology’ for the first half, host by UBI industry research last June that a small amount of chiral molecule added to the polymer OLED emissive layer controls the polarization of light emission to improve light efficiency by 60%.

Two linear polarizers applied in orthogonal form to LCD are used to transmit or block the light from the back light unit through liquid crystal movement while one circular polarizer of OLED prevents reflection of external light, which is applied as a role to increase outdoor visibility

Display companies have focused on development of device structure, optical extraction technology and material, and luminescent mechanism to compensate for more than 50% luminescent light loss due to the polarizer. We need a way to improve the efficiency of OLED using polarized light. Professor Kim, Jae-hoon has presented a method and research results to improve the OLED light efficiency in use of polarized light, emphasizing ‘the need of a new approach in a new perspective’.

<Simulation of chiral molecules-added OLED structure>

Professor Kim, Jae-hoon explained, ‘Polymer materials of OLED generate high linearly polarized light with high liquid crystallinity in general. When this light passes through a light emitting layer inclusive of chiral molecules, it becomes a circularly polarized light’. “Theoretically, the light efficiency can be increased by 100%,” he added. “This way, we can implement brighter OLED with lower power consumption.”

In application of this principle, Professor Kim, Jae – hoon and his team members have developed the OLED with luminous efficiency 60% higher than existing OLED and further research will be continued on circular polarization based on low molecular materials.

Meanwhile, the research was sponsored by the ‘Future Display Core Technology Development’ project, and the research outcomes have been published in the recent issue of an international journal, ‘Advanced Materials’.

How about the future OLED market performance?

At the seminar titled “OLED market analysis and the latest technology” host by the UBI Research at the FKI last June, the president, Lee Choong Hoon predicted the market through analyzing the OLED industry investment and mass production in the first half of 2017.

President Lee Choong Hoon emphasized that China will lead the OLED equipment market by 2021 due to increase in OLED demand of Chinese set makers. Accordingly, the Chinese equipment market is expected to account for about 48% of the entire equipment market in 2021, investing approx. US $ 40.5 billion.

It is anticipated that such movement of Chinese companies will affect the OLED smartphone market. In 2019, OLED smartphones will reverse the LCD smartphone market, accounting for 80% of the total smartphone market by 2021.

On the other hand, as for the flexible OLED, between 2017 and 2019, Samsung Electronics expects to invest heavily in BOE to be ranked second in the flexible OLED market, which should cope with the increasing demand on flexible OLED of Samsung Electronics and Apple.

President Lee analyzed that the premium TV market will be formed with larger than 65 inches as the 65-inch panels will be mass-produced at BOE’s Gen10.5 LCD plant from 2018. Consequently, panel makers without Gen10.5 will produce 65 inch panels on the Gen8 line in MMG (multi-model on a glass) method. On the other hand, LG Display is expected to continually produce TV OLED panel at Gen8, and since 2020 at Gen10.5 line.

According to ‘2017 OLED Manufacturing Equipment Annual Report’ published by the UBI research, from 2017 to 2021, it is anticipated that TFT equipment will account for 45% of the market share, followed by OLED pixel forming equipment 17%, encapsulation equipment 13%, cell equipment 13% and module equipment 12% respectively. As the demand on flexible OLEDs is expected to increase remarkably in the future, the market share of cell and module equipment will accordingly increase by 25% with high importance.

OLEDON, Find the future of AMOLED in plane source FMM!

Three years have passed since the first QHD (about 515 ppi) OLED applied to Galaxy Note4 in 2014, but OLED resolution is still in QHD. In order to manufacture high-resolution OLED over UHD, FMM of less than 15 μm is required, but it is not applied to mass production due to various technical issues.

Professor Hwang Chang-Hoon, CEO of OLEDON, a venture business of Dankook University, proposed that the plane source FMM deposition technology is the only solution for a high-resolution OLED manufacturing process over UHD at the 1H semester UBI Research Seminar “OLED Market Analysis and Latest Technology” held on June 30 (Fri) at Yeouido FKI Conference Center.

Professor Hwang Chang-Hoon said, “To improve the resolution of AMOLED, the angle of flight of organic molecules should be reduced to less than 10 degrees and the aspect ratio of TFT devices should be maintained at 1.0 level.” and explained “The evaporation angle (incidence angle) of the currently known linear source is about 40 degrees, and the shadow distance is about 3 um. Therefore, the ratio of the pattern width, the shadow distance, and the aspect ratio can be increased at the SUHD level AMOLED patterning process. Ultimately, the current patterning technology loses the flatness of the film. “.

In addition, Professor Hwang Chang-Hoon said, “Linear deposition technology has limitations in achieving resolution higher than QHD, and development of plane source FMM deposition technology is the only way to manufacture OLED with 2000 ppi or higher.”.

<Professor Hwang Chang-Hoon announced the 2250ppi AMOLED technical problem, Source: the 1H semester UBI Research Seminar>

The shadow distance measured by OLEDON’s plane source FMM deposition technique ranges from 0.68 to 1.05 μm and the angle of incidence is 13 to 19 degrees and converting this result to resolution makes it possible to fabricate a device with a maximum of 1500 ppi. On the other hand, with the newly developed Xplane source, the shadow distance was 0.38 ~ 0.56um and the incident angle was 7.2 ~ 8.0 degrees, it is possible to manufacture up to 3300 ppi device by converting it to the resolution. In the last SID2017, Prof. Jin Byung-Doo and Prof. Hwang Chang-Hoon introduced the world’s first measurement of sub-micron-scale shadow distance using plane source patterning technology, it has been announced that it is possible to manufacture a micro AMOLED device having a Super Ultra (SUHD) resolution of 11K (2250 ppi) or more if scale-up development is applied to large-area OLED display production industry in the future. (Paper title: Plane source evaporation techniques for Super ultra high resolution flexible AMOLED)

<Mirror desk OLED lighting of Hausand>

A researcher of Korea Institute of Industrial Technology said, “The average life time of OLED lighting is currently 15,000 hours at LT50 and the target life time will be 40,000 hours. From the lighting point of view, flexible and transparent design and slim thickness can generate an unlimited number of applications”. Also “In Europe, OLED is in the spotlight due to the limit of LED illumination. The lighting market has been already saturated by Chinese LED manufacturers while OLED has much more market potential.” “As the market grows, OLED lighting made in relatively simple manufacturing process will be less expensive than LED, “he anticipated.

“The lifetime of currently commercialized OLED lighting is 40,000 hours at LT50 and sufficient to use on a daily basis,” said a manager of JW M Tech, who introduced various flexible and rigid OLED lightings.”OLED emits less blue light and is superior to LED in different design applications. We will soon develop flexible OLED lighting and be most competitive in the international lighting industry,” he added.

<Flexible OLED mood light of JWM Tech>

Sungkyunkwan University introduced its self manufactured flexible OLED lighting in use of roll-to-roll process. An official of SungKyunKwan University expectantly said, “the roll-to-roll process reduces the production time and because of its thin and flexible design, it will be applied to various lightings.”

In addition, Oclass introduced mirror OLED lighting to draw great attention, and Woori Lighting’s stand-type OLED lighting in application of the wireless charging function of cell phone has been awarded by the Minister of Industry and Commerce, proving its competitiveness of OLED, the next-generation light source.

June 12, Novaled celebrates the corner stone foundation for the new company premises at Elisabeth-Boer-Strasse 9 in Dresden. On the 10,200 m² site in the north of Dresden, the Old Mill, which is under monument protection, will be renovated and transformed into a prestigious office building. As a new building, a 110-meter-long R&D plant with the best-equipped research area, clean rooms of class ISO5 and ISO7 as well as laboratories are being built. Works for the floor plate and walls of the R&D plant as well as the partial de-coring of the mill have begun. The new company headquarters offers Novaled enough space for further growth. After completion of the construction measures, the team will be able to use an area of 6,160 m² in the buildings – the best conditions for the development of materials for premium OLEDs and organic electronics.

With the purchase of the property and the decision to invest over 25 million euros in the Dresden location, Samsung SDI as Novaled parent company has made a very clear commitment to the economic region and to Novaled. Together with the city of Dresden and the state of Saxony, this step was successfully launched.

“The advantages of the new company location are obvious: best accessibility for customers, suppliers and employees; a very good infrastructure; state-of-the-art equipment and ample space for our creative team, “says Gerd Günther, CEO of Novaled. “These are the best prerequisites for driving innovation, opening up new markets, winning customers and their applications, and ensuring sustainable growth in Saxony.”

Novaled is currently worldwide the only supplier of organic dopants for OLED display mass production. The doping technology of the Samsung subsidiary Novaled is meanwhile a quasi-industry standard. Dresden’s know-how and materials are thus found in most smartphones, tablets and other devices with OLED displays. Also OLED lighting applications like Audi TT tail lights or applications like organic solar cells use Novaled technologies and materials for being high performant.

CYNORA presents record results for high-efficiency blue OLED emitters

CYNORA, a leader in TADF (thermally activated delayed fluorescence) materials for OLEDs, has reached new performance records with its newest blue emitter material. With the current performance, the company is getting close to commercialization of its first product by the end of 2017.

 

Despite urgent requests by the OLED display panel makers for a high-efficiency blue emitter material in the last few years, no material supplier has yet been able to produce such a material. High-efficiency blue emitters are needed to reduce power consumption and increase the display resolution further. At SID 2017, CYNORA presented a blue emitter with a performance that was very close to the requirements of the panel makers. Using TADF technology, the company has achieved 15% EQE at 1000 cd/m² with an emission peak at < 470 nm and a LT97 of > 90 hours (at 700 cd/m²) on a device level.

 

“CYNORA’s latest patent-protected materials show a performance in the range of the customer´s specifications for blue” said Thomas Baumann, CYNORA´s CSO, “This is the best overall performance of a high-efficiency blue emitter so far from what CYNORA has seen. In the finalization of CYNORA’s product development, CYNORA will now focus on moving the emission peak slightly towards 460 nm.”

 

“CYNORA’s progress in the last few months makes us very confident that CYNORA can commercialize CYNORA’s first highly efficient blue emitter by the end of this year, as planned” said Andreas Haldi, CMO at CYNORA. “But CYNORA’s goal is to become a leading OLED material supplier by providing emitters of all display colors. Therefore, CYNORA is planning to follow up on the blue emitter with a green emitter by 2018 and a red emitter by 2019.”

The 4th Generation Emitting Material, Hyperfluorescence

Thermally activated delayed fluorescence(TADF), still under development to complement OLED emitting materials insufficient as both fluorescence and phosphorescent materials, takes time to be commercialized at the present stage. Even Kyulux considered the most advanced company in terms of TADF technology hasn’t yet to commercialized TADF dopant suitable for display.

Adachi, CTO of Kyulux said the unprepared TADF host material is an obstacle to the commercialization of TADF, so the full width at half maximum of emitting peak is too wide to be applied to display. To solve this problem, the 4th generation hyperfluorescence is under development to commercialize the TADF material.

<Kyulux CTO Adachi>

Hyperfluorescence aims at having the effect of a phosphorescent material by adding TADF dopant to existing fluorescence host and dopant.

<Hyperfluorescence Effect>

This effect has a structure that can solve both the full width at half maximum of TADF and the low brightness of fluorescence materials as seen in the above figure, Adachi emphasized.

<Hyperfluorescence vs General fluorescence>

As seen in the above photo, Kyulux’s OLED made of general green fluorescence material and OLED made of hyperfluorescence by adding TADF to this material have a distinct difference on the same substrate.

Kyulux’s goal is to commercialize hyper fluorescence by 2017. Its target is PMOLED.

OLEDON with Dankook University succeeding in developing next-generation ultra high resolution patterning deposition technology

Chin Byung-Doo, professor at Dankook University and Hwang Chang-Hoon, professor at Dankook University and CEO of OLEDON announced that they have succeeded in developing evaporation pattern deposition technology which can realize 0.38um shadow distance (SD) at SID 2017.

Mr. Hwang, CEO of OLEDON announced at 2016 IMID Business forum that he succeeded in implementing plane source evaporation and 1.1um shadow distance with 100um-thick shadow mask. At that time, Mr. Hwang said, ‘If we reduce the step height to 3μm, theoretically, we can implement the shadow distance down to 0.38 um, so the OLED panel resolution will be possibly more than 2250ppi.’

At the SID 2017, OLEDON’s solid result of implementing SD 0.38um in application of actual plane source drew great attention from people in relevant industries regarding the possibility of mass production.

Current OLED panel production technology has the limits on implementing the resolution higher than QHD (about 600ppi) for about 3 um thick shadow which causes overlapping micro patterns in the UHD (over 800ppi) AMOLED patterning process to degrade the fine pattern density. Consequently, OLED panels are produced only at QHD level.

If OLEDON’s surface source patterning deposition technology is applied to mass production, the shadow distance can be reduced to 0.38 ~ 0.56um, which can improve the resolution about 8 times higher. In addition, if scale-up development is applied to a large size OLED display production in the future, it is possible to manufacture a micro AMOLED device equipped with super ultra resolution (SUHD) resolution higher than 3300ppi.

<Shadow data from the surface source deposition technology>

Hwang Chang-hoon, CEO of OLEDON said, ‘using the idea of primarily evaporating the organic material and its deposition on the metal surface in the vacuum environment to form organic molecular film and re-evaporate it for the second coating deposition, we have found a condition to minimize the evaporation angle of the organic molecular beam. ”

<The principle of film source presented by Mr. Hwan at the SID>

With the recent focus on display resolution, OLEDON’s research results are expected to bring significant impact on the relevant industry.

Meanwhile, Prof. Hwang Chang-hoon has been developing new deposition technology for 25 years via a deposition specialist company. He holds the original patent of surface source deposition technology (Linear organic device mass production equipment with top-down thermal induction deposition: Registration No. 101206162000).

OLED, the mainstream of HMD devices for VR

The ‘PlayX4’ opening ceremony, a next-generation augmented game show, was held at Kintex exhibition hall 2, Ilsan, Goyang, Gyeonggi-do on the 25th. During the event, a number of companies presented VR contents, using HMD (head mounted display) devices in application of OLED, such as Oculus Rift, HTC Vive and Gear VR to improve immersion and reduce motion sickness.

Realitymagiq, a professional of VR game developer, introduced a multiplay game. In reply to a question on immersion into VR, “Device performance is essential for immersive in VR, and to reduce latency, the major culprit for sickness, OLED is more than enough,” said Kim Sung-kyun, the CEO of Realitymagiq. “However, resolution needs to be further developed and so does GPU performance.”

Motionhouse Co., Ltd. has introduced MotionGear for users to experience tilting and engine vibration during actual driving. Oculus Rift OLED-applied headset, was used; “Oculus Rift was the one that could minimize the motion sickness most”, said a participant.

Latency refers to the time length for the CPU to receive information from the tracker and output, which is related to the response time of the display and the information processing of the graphics card. The response time of the display required in VR is known to be less than 3ms. Samsung Display compares the response time between OLED and LCD on the blog and emphasizes that OLED is the optimal display for VR HMD device.

In fact, many VR content companies used OLED-applied HMD devices such as Oculus Rift, HTC Vive, and Gear VR, and users seemed to enjoy VR game, not suffering from dizziness

Recently, aside from Oculus Rift and HTC Vive, many HMD makers such as recently launched Sony’s PS VR and Royole’s Royole Moon are OLED-based, not LCD, and surely the OLED application is expected to expand further.

[SID 2017] BOE, Unveiled the World’s First True QLED

BOE attracted the big attention of visitors by unveiling the world’s first 2 types of QLEDs(5 inch, 14 inch) based on electroluminescence quantum dot technology.

BOE’s 5 inch QLED has a resolution of 320 x 240 (80ppi) with LTPS TFT. On the other hands, 14 inch QLED has a resolution of 960 x 540 (80ppi) with oxide TFT.

<BOE’s 5 inch (left) & 14 inch (right) QLED display>

BOE’s QLED display this time is special because it is an ‘electroluminescence quantum dot technology’-based display without backlight, unlike Samsung Electronics’ SUHD TV based on ‘photoluminescence quantum dot’.

In general, quantum dot-based displays are categorized into two types of mechanisms: photoluminescence quantum dot and electroluminescence quantum dot.

Photoluminescence quantum dot technology has a mechanism where the material stimulated by external luminescence emits light again. Samsung Electronics applies this technology to its LCD TV by using the QD sheet attached on blue light emitting from backlight.

On the other hands, electroluminescence quantum dot technology has a mechanism that emits itself when electricity is put, and its material is inorganic and structure is similar to OLED.

Choong Hoon Yi, president of UBI Research said in analyst column that “photoluminescence quantum dot technology is applied to current LCD TVs to improve color reproduction of display. It must be the best product as LCD TV, but electroluminescence quantum dot-based display is a true QLED display”

A BOE employee explained “QLED display improves its reliability by using inorganic matters for existing OLED structure instead of organic matters, featuring better color gamut than OLED. 100% inkjet printing-based QLED is better in terms of manufacturing cost saving and large scale, compared to deposition-based OLED”.

The industry has expected that it will take more than 5 years to mass-produce QLED display, so according to BOE’s research, there’s a keen interest on how much the commercialization of electroluminescence quantum dot-based QLED is moved up or how much it influences the display industry.

JOLED said ‘Ink-jet printing is a technology for printing by applying a light emitting material, which the production process is simple and easy to expand to diverse screen size, so it has been put into practical use. The top emission, viewing angle and color reproducibility of OLED panels will be improved.’

 

In addition, JOLED has announced its plans for the future ‘to expand its inkjet printing-type small and medium-sized OLED applications (such as gaming monitors, automotive applications, etc.) or suppliers continuously.’

JOLED is a company established by INCJ, JDI, Sony and Panasonic, and is actively developing inkjet printing process. Among the panel makers, JOLED is the only company that has released a product developed by inkjet printing process in 2016.

<55inch 4K flexible AMOLED panel unveiled by JOLED in 2016>

According to Ubi research’s ‘ Market Entry Analysis for Solution Process OLED -The Possibilities and Opportunities‘, ink-jet printing is one of the process methods of the solution process, in which the ink-jet head is used to drop ink onto each pixel. Major panel makers are developing a solution process using this process, and JOLED is expected to take a lead in the future.

The solution process is capable of realizing large-area OLED panel with RGB pixel structure in Gen8 and above, has high material utilization efficiency, and is developed as a simple layer, which is advantageous in cost reduction in mass production success.

Meanwhile, Lee Choong-hoon, CEO of UBI Research, said, “Although the large-area OLED market is targeting the premium market with the WRGB method, the solution process will be the core technology since low-cost and high-production technology is key to replacing LCDs with OLEDs.”

[SID 2017] Samsung Display, Unveil the world’s first 9.1inch Stretchable AMOLED

Samsung Display unveiled the world’s first 9.1inch stretchable AMOLED, including touch, on SID 2017, boasting the world’s best AMOLED technology.

In addition to presenting a paper entitled “9.1-in-stretchable AMOLED display based on LTPS technology” at SID 2017 symposium, Samsung Display has attracted great interest in visitors by exhibiting real objects in the future display zone at Samsung Display’s.

In this 9.1 inch stretchable AMOLED, the PI is formed on the shrinkable film substrate, and then the stretchable region is patterned. And it is structured that TFT and OLED are formed on the patterned PI, and multi-touch sensor is realized at the same time.

<9.1inch stretchable AMOLED structure of Samsung Display>

In addition, stretchable AMOLEDs can be implemented in both convex and concave shapes, and up to 12 mm in concave shapes.

Stretchable display is the final technology of flexible display, so it is expected to be applied to various fields such as clothing and human skin because it does not receive any form restrictions and it is expected to create applications for new areas.

Samsung Display, which is leading the AMOLED market for mobile devices with flexible AMOLED, is expected to maintain its technological gap with latecomers once again, and also is expected how would it stimulate latecomers who are pursuing AMOLED technology at high speed.

[SID 2017] Premium TV market, LCD vs OLED war re-ignition

In the premium TV market in 2017 OLEDs seemed to catch up early with LG Electronics’ OLED TV sales volume growth and Sony’s OLED TV market gains. However, with the announcement of AUO, Taiwan’s leading LCD maker, that LCDs are more advantageous in the premium TV market than OLEDs, once again, competition between OLED TVs and LCD TVs is expected to intensify.

In the keynote session of SID 2017 held in Los Angeles, USA from May 22, AUO CEO Paul Peng made a presentation with the theme of “The warring states of display technologies” that LCDs would continue to outperform OLEDs in the premium TV market.

Paul Peng has three major claims that LCD is more dominant.

First is the performance that LCD is superior to OLED in terms of maximum size, peak brightness, ambient contrast ratio, color gamut, image sticking, and lifetime.

Second is the cost. In the black Friday in 2016, 65-inch HDR 4K narrow bezel LCD TV was US $ 1,099, while OLED was more than double with US $ 2,800.

Lastly, eco friendly. The industrial water used in the manufacturing process is used more for OLED manufacturing than LCD, and the power consumption of OLED is about twice that of LCD. The replacement cycle is 2 to 4 years for OLED, but LCD is 5 to 8 years which is more than twice as high as LCD, so is more environmentally friendly than OLED.

Since the launch of OLED TVs, there has been intense competition between LCD and OLED camps, but OLED market share continues to rise in the premium mobile market, and even in the premium TV market OLED seemed to be ahead of LCD. However, with AUO’s announcement in the keynote of SID 2017, the world’s largest display society, it is expected to intensify the fierce battle between OLED and LCD in the display industry.

Samsung Display, shows advanced product such as stretchable display in SID 2017

Samsung Display participates in ‘SID 2017’ exhibition hosted by the world-renowned Society for Display Experts ‘SID (The Society for Information Display)’ to show advanced future display products.

Samsung Display will exhibit advanced display products that have never been revealed before, such as a stretchable display and a non-eyewear 3D OLED at the LA Convention Center in Los Angeles on 23rd (local time).

Samsung Display participates in this SID 2017, and is showing the unrivaled display technology leadership and confidence by showing high-tech products and publishing outstanding papers.

Samsung Display unveiled a 9.1 inch stretchable OLED product with stretching screen.  The stretchable display is the next generation display technology that extends the screen flexibly, and it is considered to be the most suitable technology for wearable, Internet (IoT), AI (AI), and car display.

<source : Samsung Display>

Compared to the existing flexible OLEDs that can be deformed in only one direction, such as bending, folding, or rolling a screen, a stretchable OLED can be deformed in more than two directions.  This is a much higher level of implementation difficulty and is often referred to as the end point of flexible display technology in the industry.

The product displayed this time, when the screen is pressed from above, the screen is dented like a rubber balloon, and then returns to its original flat shape.  On the contrary, when pressed from below, the screen stretched up and had the elasticity to recover.  Samsung Display has developed a high level of stretchable technology that maintains the original picture quality while increasing the screen to a depth of up to 12mm when the display is pressed through steady research and development.

In addition, Samsung Display will exhibit ‘non-eyewear 3D OLED’ products. This 5.09-inch product realizes a real-life image that looks a bit different depending on the viewer’s position on the display, and expresses a more realistic 3-D image.

Especially, due to the contrast ratio close to infinity of OLED, it shows more natural stereoscopic image than LCD product. This technology is expected to be utilized in various fields requiring 3D image technology such as 3D pop-up book, 3D game, VR and etc.

 

On the other hand, this exhibition will have booths that enable users to experience the OLED technologies of Samsung Display. Including 3.5-inch size, 858ppi optimized for VR devices, 120Hz for wearable and tablet OLED products for smooth picture quality are exhibited.

In addition, much improved image quality of OLED, HDR (High Dynamic Range) and low power consumption technology can be confirmed.  Samsung Display also offers a ‘Design Innovation’ corner that introduces the development of smartphone display design, a unique flexible OLED technology.

From round OLEDs applied to mobile phones for the first time in the world after the successful production of flexible OLEDs in 2013, to recent full-screen OLEDs with the highest picture quality rating of ‘Excellent A +’ from DisplayMate, an image quality evaluation agency, it is able to show the flexible OLED technology accumulated by Samsung Display at a glance.

In addition, a high-resolution 65-type frameless LCD curved TV that minimizes screen reflections by applying ultra-low reflection POL (polarizer) and achieves 100% color expression power (DCI-P3 standard), 34-inch QHD + (3440X1440) LCD curved monitor with 21: 9 aspect ratio maximizes information transfer efficiency and 27-inch FHD (1920X1080) LCD curved monitor capable of 144 Hz high-speed screen operation are exhibited as a product that embodies innovative technology

Meanwhile, a paper entitled “Extendable Screen with Stretchable OLED Display” of Hong Jong-ho, researcher of Samsung Display Research Institute selected as SID 2017 Distinguished Paper.

Meet Prof. Adachi, the initiator of ‘Thermally Activated Delayed Fluorescence’

We visited Adachi’s laboratory at Kyushu university that published the TADF (abbr., Thermally Activated Delayed Fluorescence) thesis firstly to ‘Nature’ in 2010. He looked like a naive graduate student rather than a professor.

<Prof. Adachi , source : OLEDNET>

The reason that Prof. Adachi’s showing a full of enthusiasm for the TADF materials is that he convinces it is the best materials to lower manufacturing costs of OLED panel. Luminescence materials used in present are divided like fluorescence materials as 1st generation, and phosphorescence materials as 2nd generation. Fluorescence materials as 1st generation have a cost-effective and a low-efficiency, whereas phosphorescence materials as 2nd generation have both high-efficiency and also high-costs. This is because it utilizes the rare-earth metal, iridium. TADF as 3rd generation which Prof. Adachi has been driving, is as a structure of 1st generation materials and it has the merit of achieving the efficiency of 2nd generation materials.

TADF materials have special features that are theoretically capable of reaching 100% inter-efficiency and being free to plan molecular. It means that TADF can raise external light-efficiency up to 40%, because it is possible to form oriented materials by rod-shaped molecular planning.

About the question of the timing of commercialization of TADF materials, Prof. Adachi said that it is still insufficient to apply to OLED of Galaxy, while it’ll be possible to utilize it for products with somehow low specification from next year. It is especially expected that green or red dopant may be available. However, he also emphasized that it is essential to increase the electron transfer speed by reducing the band gap of T1 and S1 in order to be the ultimate TADF for use in displays. The electron transfer speed is currently around 1μsec, but if its speed goes up to 10-1 ~ 10-2 μsec, the lifetime would be secured due to reducing molecular degradation. He expressed about that it is necessary to actively attend by manufacturers of luminescence materials, because there are no dedicated host materials that can sufficiently demonstrate the efficiency of TADF dopant due to difficulties in developing TADF materials.

He recently put a thesis, deep blue TADF with a color coordinate of (0.148, 0.098) and external light-efficiency of more than 19.2% at German journal Angewandte.

Chinese panel makers BOE and Tianma started small and medium sized AMOLED production, acceleratedly chasing Samsung.

It is the first time for China to produce Gen6 flexible AMOLED; it is expected that BOE’s mass production not significantly affected by yield due to the tremendous support from the Chinese government will cause such impact on the small and medium-sized AMOLED market where Samsung has monopolized so far.

B7 line, which was built in May 2015 with the investment of approx. 465 yuan, is expectedly used in high-end mobile display in China, with 48K- large monthly capacity based on Gen6. In Dec last year, 45K investment was confirmed in Mianyang’s Gen6 flexible AMOLED production line B11 and mass production is expected to operate in 2019.

International TADF Workshop Opening

<Source : 2nd International TADF Workshop>

The International Workshop on the third generation of light emitting material technology, TADF (Thermally Activated Delayed Fluorescence) technology, which links first-generation fluorescent material technology and second-generation phosphorescent material technology, will be held at Kyushu University from July 19 to 21, 2017

In order to push the LCD, which is now the flagship product of the display market replacing the cathode-ray tube completely in the market, it is necessary to have a high-efficiency, low-cost OLED that can be used in mid/low-priced products. A solution to solve both high efficiency and low cost depends on the commercialization of retarded fluorescent materials.

Currently, the light emitting materials are classified into red, green, and blue host materials and dopant materials of respective colors. Among these materials, red and green use phosphorescent materials that internal efficiency is theoretically 100%, but blue materials still use fluorescent materials that internal efficiency is only 25%. Due to the limit of blue material efficiency, large OLED panels for TV have a structure in which blue layers are laminated twice, so material cost is very high.

TADF is the material that is being developed to overcome the limitations of current OLED emissive materials.

In the International TADF Workshop, headed by Professor Adachi of Kyushu University, who brought TADF technology to the world for the first time, worldwide experts of third-generation OLED lighting material development gather. Professor Adachi implied that the interest in TADF is getting hotter around the world looking from that 3 years later he published a TADF thesis for the first time in 2012 at Kyushu university approximately 120 papers published worldwide in 2015 and there are more than 200 papers published in 2016.

Professor Adachi said that the meaning of the TADF Workshop this time is to discuss with experts about the current TADF reach and future development.

At the OLED Korea Conference, Merck said, “Red shows a 16.4% luminescence efficiency and LT95 2,000h long life expectancy; for green 18.7% and LT95 8,000h; blue 7.5% LT95 500h (based on 1,000cd/m2). He once said that the corporate goal is to develop a fluorescent blue dopant with  luminous efficiency higher than 11%, a phosphorescent deep red dopant improving from 20 cd/A brightness to 80 cd/A and phosphorescent green dopant with improved roll off.”

Sony’s OLED TV, its full-fledged sales operation to start from June 10th

Sony announced on the 8th May that two models (55” and 65”) of the 4K BRAVIA OLED TV A1E series shown last Jan at CES 2017 will be launched in Japan as from June 10. Sony’s BRAVIA OLED TV is equipped with LG Display’s WRGB OLED, 4K high-definition processor X1 Extreme and acoustic surface technology which directly generates sound with the screen vibrating. A ball park price for 55-inch is 500,000 yen and for 65-inch, 800,000 yen. Sony is also planning to release 77-inch wide TV which will be expectedly launched this autumn.

The CEO of Ichiro Takagi Sony Visual products talked about the OLED TV strategies, saying ” OLED panels as well as premium models using the X1 Extreme will offer the best screen quality, sound and immersive experience”.

The Sony’s OLED TV launch is expected to bring great impact on the premium TV market currently predominated by Samsung Electronics and LG Electronics. LG Electronics, expected to compete directly with Sony, is planning to introduce new OLED TVs at a lower price than last year; the focal point is how Sony’s OLED TV will affect the commercialization of OLED TV and display industry.

In line with it, Mr. Lee, Choong Hoon, the CEO of UBI research has foreseen at the Topic seminar last April held in the conference center of Yeouido JeonKyungYeon Hall on 21st April 2017 that Sony’s OLED TV will account for about 27% of the total OLED TV market with approx. 400,000 sets to be sold in 2017, and 38% of the total OLED TV market with 3.4 million sets in 2021.

Fraunhofer FEP develops OLED microdisplays as high-precision optical fingerprint sensors

Reporter : Hana Oh(HanaOh@ubiresearch.com)

Fraunhofer FEP has been developing various application-specific OLED microdisplays based on OLED-on-silicon technology successfully for many years. This unique technology enables the high-precision integration of an OLED as light source on a microchip. Moreover this microchip can be designed with further sensor elements, e.g. photodiodes. By this, objects can be illuminated and at the same time the reflected light detected and analyzed. Such microdisplays can be integrated into interactive data eyeglasses as a “bi-directional microdisplay”: the tiny display projects the information for augmented-reality applications whereas the camera function detects the viewing direction – thus the content can be controlled by eye-movements.

The fingerprint sensor uses this bidirectional functionality of light-emission and –detection as well: the finger gets illuminated and the reflected light will be detected and analyzed.

Bernd Richter, deputy division manager for OLED microdisplays and sensors at Fraunhofer FEP explains: “We have used an extra-thin encapsulation for the chip of this fingerprint sensor. Thereby the distance between finger and image sensor has been minimized and the fingerprint can be captured excellently. Thus, an additional imaging optics is not necessary for this application.”

The first prototype has a native resolution of 1600 dpi – this is three times more than typically required by the FBI. This high spatial resolution enables the identification even of smallest sweat pores beside the typical papillary lines, which can be used to increase the security.

One of the most promising applications of this new kind of sensor is the user verification in mobile devices. Because of the particularly high resolution in comparison to the typically used capacitive fingerprint sensors these devices are much less vulnerable to so-called spoofing (the manipulation by “false fingers”).

Another nice side effect is the opportunity for using the active area as a normal display e.g. for branding, displaying logos or notifications.

<Samsung Electronics’ QN65Q8C, Source: Consumer Reports>

QLED TV QN65Q8C of Samsung Electronics launched in this year gained 79 points. Consumer Reports explained that it is excellent in resolution, image quality, and sound quality, however there was black mark for the high price in spite of backlighting existence, limit of expression for black due to backlighting and cloud phenomenon. And Consumer Reports quoted the words of industry source that it would take more than three years for launching of true self-emitting QLED TV.

In the ‘Solution process OLED annual report’, UBi research expected that QLED deposition materials have issues on a short life-span compared to phosphorescence OLED deposition materials that are currently being commercialized, efficiency problem, development of eco-friendly devices, lack of infrastructure compared to OLED. In case of not establishing infrastructure and aggressive investment such as manpower recruitment and expansion of the development investment, the time of commercialization will be far from here.

LG Electronics concentrates on ‘product competitiveness not price competitiveness’ in the premium TV market

LG Electronics reported that they plan to focus on product competitiveness rather than price competitiveness in the premium TV market in future through the conference call in Q1 of 2017 which was held on 27th, April. During the Q&A session on ‘the sales strategy of OLED and premium TV’, Jin-ho, Ha, the director of HE (Home Entertainment) said that “we will continue to expand OLED position in the premium TV market and also in future what the competitiveness we need in the premium TV market is product competitiveness rather than price’s.”

The performance in Q1 of HE in LG Electronics was 4 trillion 3261 billion won of sales volume and 3822 billion won of sales profit. It has been reduced 4600 billion won versus previous quarter under the influence of off-season. Nonetheless, YOY (Year on Year) has been kept at the same level. The sales volume was grown up in the area of North America, South Korea and Latin America for the reason of sales expansion of premium TV, though the market in Asia was decreased versus QoQ for the lack of sufficient demand.

Jin-ho, Ha, the director of HE in LG Electronics said that “We improved the profitability versus previous quarter by expansion of premium product sales, improvement of cost structure and flexible management for the panel price rise.” He also expected that the stagnant demand in whole TV market would be continued, but the demand would be increased in the area of North America, Latin America and Asia where are holding relatively high sales ratio.” In addition, “We would maintain sound profit structure and strengthen premium position by diverse global launching of products which leads the market such as ‘LG Signature OLED TV W’.”

He answered the questioning of in future panel price expectation and OLED TV line-up idea, “The panel has been significantly rising from in Q4 of 2016, and it has reached up over 60% versus June where is the lowest point last year”, and “We will design completive line-up composed of ‘premium, best, middle and low’ to aim the premium market within OLED TV group.”

For the question of the strategy in TV market in future, “In present which panel cost is increasing, we would operate the strategy based on the profitability by avoiding a simple volume competition, and we think that the market share in low price TV market is not meaningful. So that we plan to go forward the improvement of quality as a response based on the premium TV market having over 2000~2500 dollars.”

The strategy in TV market of LG Electronics announced at the conference call in Q1 2017 is consistent development of premium TV lineup which brings better profitability with high value-added product. They also expressed that will firmly build their position in the premium TV market with product competitiveness by image quality and technology rather than price competitiveness related to panel price.

And “Samsung Electronics recorded 7 trillion 2900 billion won at the display area among total sales volume in the first quarter and the sales profit was 1 trillion 3000 billion won. OLED volume occupied over 60% in the total display sales volume in Q1 of Samsung Electronics.”

Chang-hoon, Lee, the director of Samsung Display expected that “The employment of OLED panel from set manufacturers in Q2 would be consistently increasing and Samsung Electronics will maintain stable performance with response for external customers and supply flexible products to core customers.” As an expectation of OLED market in 2017, it forecasts sales growth compared to previous year by expansion of flexible product supply, however there are risks due to intensifying competition of LTPS-LCD within middle-low price market.”

Yoon, Lee, the director of image-strategy marketing team, expected that “the performance in Q1 of TV market has been decreased versus previous quarter due to off-season after peak at the end of the year, and it would show degrowth compared to previous year’s same quarter for the influence of reduced demand in the area of Europe and Latin America.” Furthermore, “It expected the performance in Q2 in TV market would slightly grow versus previous quarter as accelerating the launching of new product by company, but it will show degrowth compared to previous year’s same quarter for the effect of reduced consumption in Europe.” He also expressed that they intend to concentrate on profitability by expansion of high value-added product lineup with curved and extra-large TV along with complete sales of quantum dot QLED TV products.

During the following Q&A session, at the response of inquiry of whole OLED production line in future, “LCD 7-1 line is under switching to OLED production line from the end of 2016 and OLED A3 line is in line with plan. The investment of OLED will be progressed according to customer’s needs in the future market.”

The answer for responding question of the OLED TV, “QLED TV overcomes shortcomings of OLED TV, and it is a perfectly different product for design, image quality, and life-style of consumers with the world’s first and metal-added quantum dot material. We ended the disputes over image quality by implementing 100% color volume which maintains own color without any influence by brightness.”

For a question of delay for part supply of Galaxy S8 and S8+, “We are trying to prevent problems for the initial supply through pre-contract with involved companies and it is smoothly progressing without any difficulties. Other parts will be also supplied without any troubles through dualized operation.”

At the last question for the OLED TV development of Samsung Electronics, “We are developing a diverse technology to apply for the TV as well as OLED and now, we are concentrating upon technology development for the next generation including Quantum dot. We will strengthen the market control at the field of differentiating products, extra-large and high value-added products through a diverse new technology as well as OLED TV and catch the securement of profitability.”

LG Display, 70% of facility investment focused on large-sized OLED and POLED in this year

Merck, EU Horizon 2020 project ‘HyperOLED’ launched

Merck, a leading science and technology company, announced the successful launch of the HyperOLED project in April 12, a € 4million project funded by the European Union’s Horizon 2020 research and innovation program. Within the scope of this project, Merck, as the project coordinator, will be in close collaboration with an excellent consortium of four European partners: Microoled (France), Fraunhofer-IOF (Germany), Durham University (UK) and Intelligentsia Consultants (Luxembourg). Over a three-year period, the HyperOLED project will develop materials and device architectures for high-performance, hyperfluorescent organic light-emitting diodes (OLEDs) for use in display applications and solid state lighting.

The main objective of the HyperOLED project is to develop innovative high performance OLEDs by combining thermally activated delayed fluorescence (TADF) molecular hosts with novel, specifically adapted shielded fluorescence emitters. The HyperOLED project will directly contribute to the development of thin, organic and large area Electronics (TOLAE), which is an emerging technology with high growth potential. The project will help to create reliable TOLAE-enabled devices with increased functionality, improved performance and longer lifetimes.

The new OLEDs promise to be more cost-efficient to manufacture because they are based on white OLED stacks that are easier to produce compared to current solutions. By reducing the number of layers in the OLED stacks, around 20-40% of organic materials can be saved, tact times can be reduced and less manufacturing equipment will be required. This will lead to considerable savings throughout the whole value chain, including solvents, educts, catalysts in material synthesis, energy saving in purification by sublimation as well as energy saving in OLED production.

Furthermore, thanks to the special properties of TADF molecular hosts and novel shielded fluorescence emitters, the improvement in OLED performance is expected to eliminate the need for expensive and rare metals (e.g. iridium and platinum), creating additional environmental and cost-saving impacts.

With the broad expertise of the consortium spanning the development and production of hyperfluorescence OLEDs, the HyperOLED project will directly target high-growth potential applications. Overall, this project is expected to stimulate exciting new business opportunities and economic output for Europe and beyond.

Is Samsung Display Moving To the Gen 7 for A4 Line?

Samsung Display’s ongoing extension of flexible OLED line is highly expected to move to the gen 7 production line.

An OLED specialized research company, UBI Research CEO Choong Hoon Yi(senior analysis) analyzed the names of Samsung Display’s plants have changed by generation so A4 line will be able to increase to the gen 7.

The OLED plants owned by Samsung Display consist of A1, A2, and A3. A1 line is the gen 4 plant, A2 is the gen 5.5, and A3 is the gen 6 plant. LCD’s 7-1 line that is being recently converted is reportedly named A3E which is the follow-up of A3.

Therefore, the CEO Choong Hoon Yi forecast A4 will become the gen 7 line, in light of this trend.

To this end, he looks squarely at some issues to overcome. Firstly, it needs to secure excimer laser, the prerequisite for LTPS-TFT and doping apparatus because production equipment still remains the gen 6. But, Yi thought there is no problem in securing equipment and developing process up to the gen 7, as Samsung Display has been operating the gen 8 LTPS-TFT to produce 55-inch OLED panels for TV.

In addition, he analyzed it would be also possible to manufacture the FMM of the gen 7 half, required for the OLED deposition process. Samsung Display’s sole supplier of FMM, DNP made an investment in manufacturing facilities last year. Although the details of investment haven’t been well-known, it already has a stepper that can manufacture a mask of gen 7 half.

Lastly, when it comes to the validity of investment in Samsung Display’s gen 7, a differentiated production strategy is a key issue, according to Yi. Recently, companies that got into the business late are investing in the gen 6 OLED line, and in a few years their equipment productivity will be as good as Samsung Display’s. In his point of view, it is very meaningful to invest in the gen 7 line in order to stand out from new comers once again.

Samsung Display is already building various portfolios such as foldable OLED, COP(chip on plastic)OLED, and OLED with 800ppi high-resolution even at the R&D stage. The addition of the gen 7 production strategy to its R&D strategy incomparable with late comers will further raise its competitiveness.

ETRI’s Development of OLED Display With A Graphene Transparent Electrode

Reporter : Hana Oh(HanaOh@ubiresearch.com)

Researchers from Korea’s ETRI Institute developed a graphene transparent electrode for OLED display. Especially, they developed the process of patterning a graphene transparent electrode in exact size and shape on a large-sized substrate. Its application to smart watch requiring flexibility will be available.

ETRI(Electronics and Telecommunications Research Institute) has succeeded in developing a display with the electrode using graphene, a dream new-material, rather than using ITO(Indium Tin Oxide) that has been often used as existing electrodes for OLED display.

The successful display substrate is the current world’s largest one of 370mm x 470mm, a 19-inch monitor in size. The thickness of graphene electrodes is less than 5nm.

ETRI expects that if the graphene is deposited on flexible substrate, thin and flexible display will be feasible. Furthermore, it will become the source technology that can be used for manufacturing wearable devices applicable to clothing or skin.

In general, OLED is stacked with substrate, ITO transparent electrode, light-emitting organic layer, and anodized aluminum. The researches replaced typical ITO with grapheme.

In particular, ITO that has been used as existing electrode has a disadvantage of being made of fragile glass. Therefore, the display manufactured with this technology will clear up the problem of fragile transparent electrode.

ETRI developed graphene growth technology and oxide technology to be applied as an OLED transparent electrode by making a large-scale substrate in collaboration with Hanwha Techwin Co.,Ltd, and secured the grapheme transparent electrode fabricating and process technology with the sheet resistance of 60Ω/m² and the transmittance of 85% applicable to OLED. Especially, ETRI developed the world’s first micro-patterning process that is absolutely required for the display process.

Using this technology, ETRI successfully lighted the world’s largest grapheme electrode OLED panel of 370mm x 470mm. The finding of this study, which was published and demonstrated at 『Graphene 2017』, the world’s largest graphene conference held in Barcelona, Spain in early April, 2016, was highly acclaimed.

The researchers started to research grapheme transparent electrodes for OLED, based on the 4-year support of the Ministry of Trade, Industry and Energy(MOTIE) and Korea Evaluation Institute of Industrial Technology(KEIT) from 2012. They successfully developed a 100mm x 100mm OLED panel last year through the recent world’s largest demonstration, starting with a 7mm x 10mm coin-sized one, at the end of 2015, leading to the higher applicability of a grapheme-based display.

They said they will develop the display with a plastic substrate instead of a glass substrate. It is possible to manufacture a wearable OLED device if grapene is attached to plastic substrate, ETRI added.

ETRI’s Flexible Device Research Head Cho, Nam-sung said “The realization of a general expectation that grapheme would be applied to OLED display is very significant. We expect it will be successfully deployed on an commercial scale through large-scale grapheme film, OLED panel technology, and flexible OLED panel technology.”

This technology is expected to edge ahead from the later competitors including China as the core technology that can further increase the level of flexible OLED displays.

Capture the Rapidly Emerging OLED Parts & Materials Market

With the joining of Apple in the growing OLED market this year which is manufactured by Samsung Display and applied in Samsung Electronics’ Galaxy, the OLED parts & materials market is increasingly developing.

 

An OLED specialized research company, UBI Research CEO Choong Hoon Yi(senior analysis) said the various parts & materials market needed for manufacturing smartphone OLED is expected to reach US$ 8.7billion this year and more than quadruple to US$ 38billion in 2021.

<M2017 Mobile Phone OLED Parts & Materials Report, UBI Research>

The biggest reason for the rapid growth in the smartphone OLED parts & materials market is attributed to the stable success of Samsung’s Galaxy, the Apple’s effect, the Chinese set companies’ demand boom. Just like reflecting this trend, leading display companies such as LG Display, BOE, CSOT, and Visionox following Samsung Display are struggling to introduce the 6th generation flexible OLED manufacturing line. This trend will lead LCD to disappear almost in the smartphone market by 2021.

<2017 Mobile Phone OLED Parts & Materials Report, UBI Research>

As the OLED parts & materials market for smartphone is classified by country, the Korean market predominates. The Korean OLED parts & materials market accounts for 95% of the total market and is likely to keep 72% in 2021.

 

As the OLED industry is led by Samsung Display, the Korean parts & materials market is also expected to rapidly grow. UBI Research CEO Choong Hoon Yi forecasted the ecosystem made by Samsung Display is held by the majority of Korean SMEs or the foreign companies with a factory in Korea, OLED growth will be directly related to the development of Korean SMEs.
