/in /by

At the 28th FINETECH JAPAN held in Makuhari Messe, Japan during December 5-7, 2018, Hiroyuki Hara, manager of Denso said that OLED will be used as future automotive displays due to their various advantages.

Hara refers to the large screen including the touch panel as the latest trend of automobile display, and now LCD is mainly used. However, OLED is expected to be used more and more in automobiles as the automotive electronics makers and drivers demand high-quality displays.

Saying that key elements in automotive displays are high contrast ratio, wide viewing angle, design autonomy, light weight, low reflection and reliability, Hara emphasized that the display that can satisfy all of these key elements is OLED. In addition, the factors related to image quality such as contrast ratio and viewing angle are directly related to safety for the driver. Thus, OLED is to be adopted more. Referring to the requirements of automotive OLED, he finally commented that improving reliability, such as lowering the luminance drop due to temperature changes and preventing damage to OLED due to high humidity, will be key to OLED for its entry into the automotive display market.

The automotive display is likely to lead the market for next-generation displays following mobile devices and TVs. Various OLED panel makers such as BOE and Visionox, as well as LG Display and Samsung Display, are showing automotive displays at domestic and international exhibitions. Denso also invested Japanese yen 30 billion in JOLED early 2018 to compete with Korean panel makers. Meanwhile, the market for OLED displays for automobiles led by Samsung Display and LG Display is expected to grow to US$ 540 million in 2023 according to UBI Research’s recently published “Automotive OLED Display Report”.

5G communication technology introduced from next year can process higher image quality and large-capacity contents such as VR more rapidly, besides real-time streaming service. As the communication speed increases, the relevant contents, are expected to be released, which require high resolution and large screen with graphics detailed.

The current smart phone is getting bigger up to 6 inches, but it is not enough for 4K resolution of 5G communication age. Since 4K resolution is to be possible at 7-inch and larger displays, they might be the most suitable product for the 5G communication era. Foldable smart phones are digital convergence products that can function as smart phones and tablet PCs as the next generation mobile devices that use 7 inch or more displays but maximize portability.

Owing to foldable OLED, foldable smart phones are likely to be available. Several companies have rushed to produce various prototype foldable OLED displays at exhibitions and conferences. A few panel makers even pledged to mass-produce foldable OLED displays competitively. OLED display companies worldwide including Samsung Display have invested enormous development costs in order to preempt the next generation product market, and now foldable OLEDs are starting to appear.

Samsung Electronics, which is leading the OLED smart phone market, is planned to launch the in-folding type foldable phone for the first time in the world next year. Accordingly, Samsung Display has prepared 1.5R foldable OLED. For Samsung Electronics, which has suffered sluggish sales of the Galaxy S series, Foldable Phone is a super premium product that needs to be succeeded.

However, foldable OLED is not a product that anyone can produce. Since foldable OLED has a more complex module structure than conventional flexible OLED, it is necessary to overcome the changes in various panel characteristics caused by folding. Especially in in-folding type foldable OLED, compensation circuit technology to overcome TFT resistance change and resilience required when folding and unfolding screen are typical technical difficulties. In order to realize this technology, the key challenges of reducing stress at the area of folding, selecting a proper substrate, determining the ideal stack structure, and optimizing the liftoff process, need to be overcome. Even when folding over 200,000 times, it is required to have reliability that there will be no abnormality on display image quality and surface.

“Foldable OLED Report” published by UBI Research analyzes the development trends of panel makers together with the development issues of major films that determine the reliability of foldable OLED.

Mr. Atsushi Ban, Vice President of Sharp presented a future strategy that combines IGZO and OLED through a keynote session at the 28th FINETECH JAPAN, held in Makuhari Messe, Japan from December 5, 2018.

Ban emphasized “The proportion of OLED in the entire display market is expected to grow even higher, and the new value of OLED is no different than flexibility.”

He said, “Sharp is also planning a variety of applications using the thin, light-weight and flexible characteristics of OLED. From the third quarter of 2018, its Taki plant has produced 4.5G backplanes and the Sakai plant is under injecting glass for OLED and module processing for 4.5G 15K quantity.”

Ban also pointed out the possibility of expanding the OLED industry through flexible OLED, commenting that Sharp’s next goal is to develop foldable OLED that combines IGZO. Sharp has pioneered a new display technology, called IGZO, which has been known for its semiconductor properties for years, but Sharp has developed a crystalline form that maximizes its benefits for greater display performance, and IGZO improves the performance of display panels in three significant ways: lower power consumption, higher resolution and special benefits for touch-sensitive displays. Ban expected that it could create new value if IGZO is combined with medium to large sized foldable OLED or rollable OLED.

Finally, Ban introduced Sharp’s IGZO development roadmap and announced that it will develop much improved IGZO.

Fingerprint Full-Screen Smart Phones Begin to Compete

/in /by

<Vivo’s full screen smart phone with in-display fingerprint scanner, Android authority>

The competition for front fingerprint recognition of smart phones is expected to become hot.

In the smart phone with the existing home button, the front fingerprint sensor was installed on the home button. Fingerprint security enhances security, but recently, full screen Smartphone without home button has been released and fingerprint sensor has been moved to the back of Smartphone. This has caused disadvantages such as an uncomfortable hand shape when touching a finger to the fingerprint sensor and fingerprints on the camera lens.

In order to improve these points and to implement a complete full-screen Smartphone, the development of integrating full-screen fingerprint recognition with display is continuing.

The method of full-screen fingerprint recognition is largely examined by both optical and ultrasonic methods. The optics are inexpensive and easy to mass-produce, but the OLED substrate must be transparent because the sensor is to be located below the OLED panel. Therefore, it is applicable to rigid OLED using glass as a substrate, but it is difficult to apply to flexible OLED using colored PI as a substrate. The ultrasonic method is most stable in accuracy and durability, but it has a disadvantage of high manufacturing cost.

Currently, Chinese set makers have begun to launch smart phones with optical front fingerprint recognition. The Galaxy S10, which will be released next year by Samsung Electronics, is being watched for the adoption of ultrasonic full-screen fingerprint recognition. LG Display is also developing a display with front fingerprint recognition.

As such, the sales for full-screen smart phones with front fingerprint recognition are expected to be started in earnest. Competition in the smartphone market is expected to become more intense in the second half.

Having a Gen5.5 7.5K line in Shenzhen, Royole is known as a head mount display (HMD) company rather than a display company. After completing installation of equipment in the second quarter of this year, Royole has been developing panels for the target of 7.8-inch tablet PC.
RoYole has two peculiarities in OLED field. One is the world’s first mass-production of foldable OLEDs and the other is the first use of oxide TFTs in mobile displays.

Source: Royole Homepage

Because plastic film is used for the cover window of foldable phone, the display of out folding foldable phone is very likely to be damaged due to the external environment.

In fact, Samsung Display already developed a QHD resolution outfolding foldable OLED with a bending radius of 5 mm a few years ago, but the company plans to mass produce infolding foldable OLED to minimize damage to the screen from December.

Since Royole has not yet produced products with oxide TFT, the company has not achieved complete TFT reliability. Because of very low yield for the time, the available supply volume is expected to be limited even if the sales begin.

OLEDON, is to announce belt-plane source deposition technology for manufacturing ultra-high resolution and ultra-area OLED

/in /by

Plane source technology, which was first developed by OLEDON in the world, has the principle of depositing the first organic material on the metal surface and evaporating it upwards to produce fine pattern of 2250 ppi, which is ultrahigh resolution. In this plane source process, three processes such as the first deposition, the plane source inversion, and the second evaporation are necessary, and the number of the high vacuum chambers is increased when the mass production is applied. The belt plane source FMM deposition technology introduced by OLEDON has a concept of carrying out the above processes at a time in one evaporation equipment. This is a continuous plane source supplying deposition technology in which the metal surface is formed in a belt shape.

Hwang added, “Using vertical plane source enables smooth deposition process for the 12th generation class area substrate for QD-OLED TV without sagging problem. Vertical belt-plane source evaporation equipment adopts the concept of depositing the substrate in a standing-up position so that the load on the framed glass chuck and the open mask is very low. Thus, easy transportation of the substrate, and uniform deposition process of thin film over a very large area in the static state are possible.” This technology is expected to be applicable not only to the 8th generation but also to the cluster type mass-production evaporator with substrate sizes more than 10 generations in the future.

Room mirror and side mirrors of Smart Car will be replaced by OLED

/in /by

Japan Electronics Show, CEATEC2018, was held at Makuhari Messe last week. CEATEC JAPAN 2018 is a global showcase for Japan’s growth strategies and vision of the future. Various Japanese companies exhibited products centered on IoT robots and AI. It is recognized that the electronics industry in Japan is gradually shifting from large hardware to small advanced parts and software industries.

In the exhibition, the core technology of smart car was introduced for self driving. Kyocera introduced cockpit technology that can anticipate and prevent various accidents that may occur in blind spots as advanced sensing technology and image processing technology to enhance the safety of automobiles.

For automotive display business, the company also exhibited advanced concept cars with clusters, CIDs, room mirror displays and side view displays.

According to Kyocera officials, room-mirror and side-view displays that show the external environment might have limitations and need to be converted into OLED displays since all of the concept car’s displays use LCDs.
When LCDs are used for room mirror display and side view display that show rapid changes while driving at high speed, the location of surrounding cars is to be expressed as being behind the actual location, which can result in an accident. In particular, LCDs with low contrast ratio are not able to accurately represent external objects at night.
OLEDs with high-speed response and high contrast ratio are expected to dominate the future automotive room mirror and side view mirror market.

 

 

[ICEL 2018] TADF attracts attention as next generation emitting material

/in /by

In addition to monitors and virtual reality devices, OLED is gradually expanding its domain beyond smartphones and TVs, inclusive of the application of side-mirror OLED in automobiles. As new OLED applications are increased in various environments, it is essential to develop technologies to satisfy users.

In ICEL 2018, which is being held at Jeju International Convention Center from October 15th, many presenters and attendants emphasized that material development is essential to improve the performance of OLED as the OLED market grows more. As an alternative material, TADF (Thermally Activated Delayed Fluorescence) is mentioned.

First, Hwang Seok-Hwan, chief researcher in Samsung Display said that TADF is to be a good resolution as one of emitting materials for new deposition process, referring to the continued growth of OLED panel and material market.

Hwang said that the efficiency of fluorescent Blue is almost saturated, so 100% luminance efficiency can be obtained theoretically by applying TADF with the advantages of not using expensive rare earth metals. He added that improvement of material stability, improvement of color purity by using boron material, development of host having high triplet energy need to be superseded.

Also, CYNORA, a leading TADF developing company, disclosed the performance of dark blue TADF developed so far.

CYNORA said that the luminance efficiency and color purity of dark blue TADF reached the level that the related companies required, and that its current goal is to develop the technology to improve lifetime. In addition, based on this know-how, the company will quickly develop green and red TADF, and now green TADF has been delivered to several customers as a sample.

Merck confirmed that TADF is the most powerful luminescent material to replace fluorescent Blue at its presentation together with a poster about TADF.

OLED companies and research institutes are focusing attention on whether blue TADF can quickly enter OLED market and upgrade OLED performance further.

At ICEL 2018, held at Jeju International Convention Center from Oct. 15, Soo-Young Yoon, Vice President and Head of LG Display Laboratory, presented the challenges for the OLED TV performance improvement and price reduction

Yoon said “In 2018, the future prospects of OLED TVs have changed more positively compared to that in 2016. In 2013, only LG Electronics was an OLED TV set maker. The number of OLED TV set makers has steadily increased; ten in 2016, and fifteen in 2018. Many TV set makers are choosing OLED. ”

He added that although OLED TV is on the track of success with lots of improvement, it has to be further developed. The challenge is the improvement for high brightness, color reproduction rate and with the development of 8K resolution. Also he mentioned that the price reduction is to be necessary.

Yoon explained that the development of components such as driver IC and controller is an important task to develop 8K OLED TV. In order to improve the brightness, color reproducibility, and lifespan, TADF and phosphorescent Blue are to be good alternatives for improving the RGB emitting materials. The enhancement of out-coupling is also important.

In addition, he referred to the solution processed OLED as a technology, to compete against LCD TV price, with the necessity of developing inkjet equipment, process, and soluble materials. For this, it is required to develop the ink jet equipment and shorten the process time for mass production, but the performance and reliability of the soluble materials will be more important.
Finally, he commented that the company will focus on 8K OLED TV and rollable OLED TV with the improvement of brightness until 2020. After 2022, the company will develop the OLED TV which has an enhanced brightness of 300 nits or more, a color gamut that satisfies BT.2020, and a lifespan of more than 30,000 hours.

CYNORA announced that it has extended its joint development agreement for TADF commercialization with LG Display.

TADF developer CYNORA has announced that it has extended its joint-development agreement with LG Display. The two companies have been co-developing deep-blue TADF OLED emitters for two years, and have now decided to continue the cooperation towards the commercialization of TADF emitters in OLED displays.

The performance of CYNORA’s latest deep-blue material was presented at IMID 2018 held in August of the year. Among the performance introduced, the CIEy is 0.13, the EQE is 20% based on 1000 nits, and the LT97 is 15 hours at 700 nits.

CYNORA CEO Gildas Sorin commented, “Currently, CYNORA focuses on the development of deep blue TADFs for OLED TVs. Through the accumulated know-how to develop deep blue TADF, it also has plans to develop a light blue TADF for lighting applications and a green TADF for displays.”

The golden market for Automotive OLED Displays is approaching.

/in /by

The display of connected cars is getting bigger and bigger to for the convenience of providing various information. The displays used in general vehicles include the cluster, CID (center information display), RSE (rear seat entertainment), and RMD (room mirror display). In connected cars, various buttons of the center fascia are displayed, and a display is attached to the door using a camera instead of a side mirror. The Audi e-tron®, all-new electric Sports Utility Vehicle (SUV) feature a small side-view OLED display instead of the existing side mirrors. According to Choong-Hoon Yi, CEO of UBI Research, the reason why automobile manufacturers are actively trying to use OLED displays is because OLED can be a good resolution in various aspects such as design, visibility and thickness. Since the side view camera is attached to the door, the viewing angle should be very good for the driver’s eyes. Especially in nighttime driving, black should be accurately represented on the display to make things clearer. In addition, OLEDs with fast response must be used for the mirror of car because the screen needs to be changed rapidly depending on speed of the car (if it is running at a high speed). In winter season when temperatures are low, LCDs with slow response times are not recommendable to be used.

Flexible OLEDs should also be used to mount the cockpit display on the dashboard that maximizes driver’s convenience.

<BenzのF015 cockpit displayとAudiのe-tron side view display>

In contrast, LG Display, the strongest player in the market for OLED TVs, is looking for the display market for clusters and CIDs as flexible OLED with two layers of RGB OLED. Visteon, the second-largest supplier of automotive displays, is preparing for the cluster market with LG Display’s pOLED. Since 12.3-inch p OLED is made of LTPS substrate and its OLED process is more complicated than that of OLED for smartphone, panel prices including module are expected to be equal to 55-inch WRGB OLED, which can create a premium market even if the quantity is small.

<Visteon, 12.3 inches pOLED>

According to “Automotive OLED Display Report” published by UBI Research, the market for automotive OLED displays led by Samsung Display and LG Display is expected to grow to US$ 540million in 2023.

Samsung Display announced on October 3 that the company will be supplying a 7-inch OLED display for Audi’s all-new electric Sports Utility Vehicle (SUV), the Audi e-tron®. The Audi e-tron has attracted attention throughout the automotive industry. One of its highlights are optional* ‘virtual exterior mirrors’ – a ‘first’ for a volume-production car.

Audi’s virtual exterior mirrors feature a small side-view camera instead of the existing side mirrors. The driver can view the images captured by the camera in real time through the OLED display installed between the vehicle’s A pillar (the column next to the front glass) and the door.

<Virtual exterior mirror applied to e-Tron, Audi, Source: news.samsungdisplay.com>

The OLED display supplied by Samsung Display is equipped with one camera on each side of the vehicle dashboard, replacing the existing side mirror function, and the built-in touch sensor allows people to zoom in or out on the screen as if to manipulate a smartphone. Audi said the Virtual Exterior Mirror offers a wider field of view without blind spots, compared to a typical side mirror. It provides better visibility even on cloudy days and in dark places, and it provides a ‘view mode’ suitable for each driving situation such as highway driving, rotation, parking, etc for more convenient and safe driving. By eliminating the side mirrors that protrude out of the vehicle, it reduces air resistance and wind noise. Also, slim and beautiful design is possible, reducing the body width by 5.9 inches.

The images seen on the Samsung display that covers each virtual exterior mirror appear natural and distinct with none of the drag effects typically triggered by a slow response rate at low temperatures, while exhibiting outstanding color reproducibility. The Samsung 7-inch OLED display provides Audi e-tron drivers with an ideal visual solution, thanks to its low power consumption and innovatively thin, lightweight design, in addition to its superior imaging.

Jeeho Baek, Senior Vice President of Samsung Display, said “It is inspiring to many that our OLED display is used in Audi’s virtual exterior mirror, demonstrating that Samsung OLED technology is being optimized for cutting-edge automobile systems around the world. We will continue to actively support leading automotive manufacturers in helping them to advance the future automotive market through the use of our OLED display technology with its high resolution, advanced designs and low power consumption.”

 

 

OLEDON develops vertical plane source deposition technology for large OLED TV manufacturing

/in , , , /by

Hwang Chang-Hoon, CEO of OLEDON, which has developed plane-source deposition technology for small & medium-sized OLED and large area OLED, said that it is under development of vertical plane source deposition technology capable of manufacturing ultra-large OLED TVs of 77 inches or larger. Hwang introduced the related technology that it is possible to mass produce OLED TVs of 77 inches or more without the sagging problem of large substrate such as 12th generation (3300 x 4000 mm) substrate when using vertical plane source deposition technology.

According to Hwang, the production yield for 75 inch TVs or larger with the conventional inline type evaporator might be very low due to severe sagging of the substrate and difficult control of many linear sources. To solve this problem, Hwang said that a new 12-generation large-area cluster-type deposition technology is needed, and that vertical plane source deposition technology will be an appropriate alternative.

On the other hand, OLEDON holds the original patents for plane source deposition technology. It also filed a patent related to the curved plane source FMM deposition for high-resolution AMOLED manufacturing, and a patent related to the vertical plane source deposition technology for manufacturing large-area OLED TV.

The color coordinates of the yellow hyperfluorescence revealed by Junji Adachi are (0.49, 0.50), the FWHM (Full Width at Half Maximum) is 76 nm, the EQE is 15.7% on 1000 nit basis, and the LT50 is 62,000 hours by 1000 nit. And the color coordinates of the green hyperfluorescence are (0.28, 0.65), the FWHM (Full Width at Half Maximum) is 31 nm, the EQE is 20.6% on 1000 nit basis, and the LT50 of 1,000 nit is 48,000 hours.

Junji Adachi also revealed the performance of Blue hyperfluorescence, which is currently under development. The maximum emission wavelength of the blue hyperfluorescence is 470 nm, the EQE at 1000 nit is 22%, and the LT50 at 750 nit is 100 hours. In particular, he predicted that the performance of Blue hyperfluorescence would be further improved in the future, saying that it began to improve rapidly in the first half of 2018.

In the following announcement, Dr. Georgios Liaptsis of CYNORA explained about the deep Blue under development, emphasizing that the wavelength should be 460 nm and the CIEy should be within 0.15. He revealed its performance, adding that CYNORA has been carrying out the necessary research to make the lifetime of deep Blue as long as that of sky Blue even with phenomenon that the life span is getting longer as the Blue goes closer to the sky Blue

Fluorescent blue is currently used for the Blue of all OLED applications. Attention is growing whether Blue TADF or Blue Fluorescence can be commercialized to realize better efficiency and lifetime than existing fluorescent blue.

[IMID 2018] Samsung Display, The key material that will connect the smart world and the individual in the future is the display

/in /by

At IMID 2018 held in BEXCO, Busan, Korea on August 29, Kwak Jin-Oh, vice president of Samsung Display, delivered a keynote speech on the theme of ‘The Infinite Evolution with Display’. He emphasized “Display will be the key material to link to the smart world and the creation of a new world and environment will be accelerated.”

Comparing the evolution of living things with the evolution of displays, Kwak pointed out the direction of the next-generation displays such as ‘size diversity from small to large size, adaption in design inclusive of full screen and flexible, and convergence with other technologies’.

In terms of size diversity, Kwak said, “High-resolution displays that can feel realism in small and medium-sized area, and displays that can be immersed like a big screen in a movie theater in large area, are required.”

The design adaptation then was referred to design autonomy as one of the values of next-generation displays. He further emphasized the value of rollable and stretchable displays as well as foldable displays in small and medium sized displays.

Kwak said that Samsung is developing rollable displays as well as foldable displays that are currently attracting great interest. Unlike foldable display, rollable display requires consideration of the stress on the front of the panel. He commented “Because there are many things to consider such as the time when it is rolled up, and the number of times it is rolled and unrolled, the company is conducting research to solve them.”

He also introduced a stretchable display that can implement patterns freely, and explained that it is developing various structures using RGB pixel unit and stretchable unit to implement displays that have high reliability with low stress.

Mentioning about biotechnology at the convergence area, he pointed out that new fusion technologies need to be considered such as measurement of oxygen saturation by transmitting light to hemoglobin or changes in the wake up mode and sleep mode of the display depending on the melatonin change.

Finally, Kwak concluded that display is evolving to create a new society and environment, emphasizing that display is the key material to link between the individual and the smart world in the forthcoming 5G era.

[IMID 2018] LG Display, showcased 2-stack RGB OLED for automobile OLED with improved life span.

/in /by

At IMID 2018 held in BEXCO, Busan on August 29, Kim Kwan-Soo, research fellow of LG Display presented about a new OLED technology for automotive displays.

Kim said that RGB OLEDs applied to mobile devices and WRGB OLEDs applied to TVs do not satisfy customers’ needs in terms of life span. To solve this issue, he introduced 2 stack RGB OLED in which RGB OLED has the same tandem structure as WRGB.

Because 2 stack RGB OLED can be thick due to adding a layer of CCL (charge generation layer) to the multi-layer structure, HTL is made thinner than before and the charge balance of the emitting layer is optimized.

As a result, the 2-stack RGB OLED shows 1.5 ~ 2 times higher emitting efficiency than the 1-stack RGB OLED. Its lifetime is increased by 4 times on T80 basis.

However, the 2-stack structure has a disadvantage in that it has higher power consumption than the general structure. Thus, it is necessary to make efforts to solve this disadvantage.

[IMID 2018] LG Display and Samsung Display exhibited a large number of large, and small & medium sized OLED applications.

/in /by

LG Display and Samsung Display introduced a number of applications using OLED at IMID 2018 held in BEXCO, Busan, drawing attention from many visitors. In particular, LG Display displayed its strategies mostly for large OLED applications such as 77-inch transparent OLED and 55-inch video wall OLED, while Samsung Display introduced the small and medium sized OLED applications mainly for automotive and virtual reality devices.

First, the panel thickness of the 77 inch transparent flexible OLED introduced by LG Display is 400 μm, the bending radius is 80 mm, and the luminance is 200 nit based on full white.

LG Display explained that it would improve the required transmittance and durability. Also, it commented that the goal is to reduce bezel to 0.5 mm at its display of 4 FHD OLEDs with 3.8 mm bezel.

In addition, LG Display presented a 1200ppi 4.3-inch WRGB OLED for virtual reality devices. One official explained that WRGB OLED, which represents the resolution by etching the color filter, would be advantageous for higher resolution than RGB using the deposition method.

Meanwhile, Samsung Display exhibited a number of automotive OLEDs, including unbreakable OLED for 6.22 inch steering wheel, 1000R curved OLED for passenger monitor, transparent OLED for HUD, S-curved OLED for CIO and rollable OLED. The concerned official expects the OLED to be widely applied to inside automobiles because it has excellent design autonomy, compared to LCD.

He added “Although there are many things to be improved, such as brightness and reliability, it is continuously improving the required performance through the feedback from European customers”.

Furthermore, Samsung Display showcased light field display and 2,000ppi resolution RGB OLED for virtual reality devices.

[IMID 2018] OLEDON, developed ‘curved plane source FMM deposition technology’ for 2250ppi AMOLED for the first time in the world

/in /by

OLEDON is a company which develops plane source deposition technology for high resolution AMOLED manufacturing. Hwang Chang-Hoon, CEO of  OLEDON announced in IMID 2018 that it developed ‘curved plane source FMM deposition technology’ that can be adopted to 2250ppi AMOLED pixels, for the first time in the world.

Conventional linear source FMM deposition technology has a shadow distance of 3um. The available production range is 570ppi AMOLED resolution. On the other hand, the plane source deposition technology already demonstrated in OLEDON can achieve a resolution of 800 to 1200 ppi of AMOLED with a shadow distance of 0.8 to 1.5 μm. Meanwhile, the newly developed ‘curved plane source FMM deposition technology’ is an upgraded technology of the plane source deposition technology which can realize the maximum resolution of AMOLED to 2250ppi with a shadow distance of 0.18 ~ 0.6μm.

The principle is that light is gathered through a concave mirror, a curved surface is applied to the conventional flat plane source, and the light emitting material does not spread, but is precisely deposited at a desired position, thereby reducing the shadow distance.

If this technology is commercialized, it is expected that it can be widely applied not only to mobile devices but also to virtual reality devices.

JOLED raised 47 billion yen to spur solution process OLED business for automobiles.

/in /by

JOLED, the world’s first to successfully commercialize solution process OLED products, announced that it had raised a total of 47 billion yen as a third-party capital increase.

According to JOLED, Denso will invest 30 billion yen, Toyota Tsusho 10 billion yen, Sumitomo chemical 5 billion yen and SCREEN Finetech Solutions 2 billion yen. JOLED is known to cooperate with Denso to develop automotive displays and Sumitomo chemical to develop OLED materials for solution process.

In particular, Denso has been mainly using TFT-LCD for automotive displays, but it is expected to lead the development for applying lightweight and easy-to-shape OLED to automobile interior through this investment.

It is expected that this funding will accelerate the establishment of production system for the mass-production of JOLED’s solution process OLED. JOLED announced on July 1 that it would set up a “JOLED Nomi Office” in Nomi-city, Ishikawa, and aim to operate in 2020.

Major production products are medium-sized (10 to 32-inch) solution process OLEDs that will be used for cars or high-end monitors. Also, Toshiaki Arai, chief technologist of JOLED announced that they would target the middle-sized OLED market with solution process OLED, at the 2018 OLED Korea conference hosted by UBI Research in March.

 

Fingerprint full-screen smart phones begin to compete

/in /by

<Vivo’s full screen smart phone with in-display fingerprint scanner, Android authority>

The competition for front fingerprint recognition of smart phones is expected to become hot.

In the smart phone with the existing home button, the front fingerprint sensor was installed on the home button. Fingerprint security enhances security, but recently, full screen Smartphone without home button has been released and fingerprint sensor has been moved to the back of Smartphone. This has caused disadvantages such as an uncomfortable hand shape when touching a finger to the fingerprint sensor and fingerprints on the camera lens.

In order to improve these points and to implement a complete full-screen Smartphone, the development of integrating full-screen fingerprint recognition with display is continuing.

The method of full-screen fingerprint recognition is largely examined by both optical and ultrasonic methods. The optics are inexpensive and easy to mass-produce, but the OLED substrate must be transparent because the sensor is to be located below the OLED panel. Therefore, it is applicable to rigid OLED using glass as a substrate, but it is difficult to apply to flexible OLED using colored PI as a substrate. The ultrasonic method is most stable in accuracy and durability, but it has a disadvantage of high manufacturing cost.

Currently, Chinese set makers have begun to launch smart phones with optical front fingerprint recognition. The Galaxy S10, which will be released next year by Samsung Electronics, is being watched for the adoption of ultrasonic full-screen fingerprint recognition. LG Display is also developing a display with front fingerprint recognition.

As such, the sales for full-screen smart phones with front fingerprint recognition are expected to be started in earnest. Competition in the smartphone market is expected to become more intense in the second half.

Samsung Electronics, Display Business division’s operating profit in the second quarter of 2018 was KRW 140 billion.

/in /by

Samsung Electronics announced its sales of KRW 58.48 trillion and operating profit of KRW 14.87 trillion through the earnings conference call of the second quarter, 2018 on July 31. Its sales decreased by 4% YoY and the operating profit increased by KRW 800 billion. Sales decreased 3% QoQ and operating profit fell by KRW 800 billion QoQ.

According to Samsung Electronics, the display panel business recorded sales of KRW 5.67 trillion and operating profit of KRW 140 billion, due to slowing demand for flexible OLED panels and declining sales of LCD TV panels. Despite improved utilization of rigid OLED, OLED division’s earnings declined QoQ due to continued weak demand for flexible products.

Competition with LTPS LCD is expected to intensify at rigid OLED in the second half of 2019, but earnings are to improve on increased sales following the recovery of flexible product demand. Sales and operating profit are projected to improve in the second half on the back of production of flexible OLED for Apple’s new iPhone models from 2Q.

Samsung Electronics plans to expand its share of OLEDs for mobile devices by strengthening its differentiated technology and cost competitiveness, and to strengthen its capacity for new products such as foldable OLEDs. Samsung official said that foldable OLED will contribute to growth from next year rather than immediate performance in the second half of the year.

IT • Mobile (IM) division posted sales of KRW 24 trillion and operating profit of KRW 2.67 trillion. Operating profit fell 34.2 percent from KRW 4.06 trillion in the same period a year ago, and also fell sharply from the previous quarter (KRW 3.77 trillion). In 2Q, handset sales reached 78 million units, of which 90% are smart phones. 5 million units of tablet were sold. The average selling price (ASP) of the handsets is in the second half of US$ 220. The Consumer Electronics (CE) division posted sales of KRW 10.4 trillion and operating profit of KRW 510 billion in the second quarter of the year. Overall sales and operating profit of the first half of the year were KR W 20.14 trillion and KRW 0.79 trillion, respectively. TV profits improved thanks to robust sales of high value-added products such as QLED TVs amid the global sports events. On the other hand, SEC’s facility investment in the second quarter was KRW 8 trillion. By business, semiconductor area accounted for KRW 6.1 trillion and KRW 1.1 trillion was invested for display area. In the first half, a total of KRW 16.6 trillion was invested; including KRW 13.3 trillion in semiconductors and KRW 1.9 trillion in display.

LG Display, Showed OLED lighting for unmarried mothers

/in , /by

LG Display delivered 30 OLED lighting units, made by its employee volunteers, and baby products to 30 unmarried mothers.

This volunteer activity was carried out by the talent services of OLED lighting employees. OLED lighting business division donated 30 flexible OLED lighting panels, and the product planning team customized the lightings for breastfeeding for unwed mothers.

On July 27, the employee volunteers assembled light fixtures, which were customized by woodworking parts through social enterprises, and panels as finished products. In addition, various items needed for a baby and cheer letters for the unwed mothers were packed together. The packaged gift sets were delivered to 30 unmarried mothers living at the unmarried mothers’ facilities through the Eastern Social Welfare Society on July 30.

OLED lighting reduces light flickering and blue light, which affect eye health. And its mild light protects you from eye fatigue. It is also regarded as an eco-friendly product because it generates less heat and has no harmful substances. Since it is the organization that best knows the characteristics of OLED lighting, it suggested the service of delivering the OLED lighting for breastfeeding, made by its members, suitable for the baby-care environment.

Kim Yong-Jin, manager of the OLED lighting sales team who participated in the volunteer service, said “I feel it was worthwhile to deliver the OLED lighting directly to the necessary neighbors although I have dealt with it for business. When I see the neighbors who were delighted with little help, I have to think once again that service activity is so much fun.

How much will be the investment cost for 8Generation QD-OLED TV?

/in /by

In the “2018 OLED Equipment Report” recently published by UBI Research, the required investment cost was analyzed for the QD-OLED that Samsung Display started to develop.

QD-OLED, which is being developed by Samsung Display, is a method of displaying three colors of RGB by separating green and red from the light emitted from blue OLED through QD (quantum dot) material. The light passing through the QD material once again passes through the color filter and displays a richer color.

QD-OLED is similar to the manufacturing method of WDRGB OLED produced by LG Display. First, both companies use oxide TFTs. At WRGB OLED, blue is applied twice and red and green are deposited between them. In contrast, QD-OLED is fabricated by depositing only blue material twice. Both methods use the open mask with an empty center.

For both QD-OLED and WRGB OLED, the color filter manufacturing cost is assumed to be same; however, QD-OLED should be equipped with additional equipment to coat QD materials.

According to the report, it is expected that the investment cost is to be equal because the similar equipment can be used for module, cell, encapsulation and evaporator. Since WRGB OLED is bottom emission type, it is formed together when backplane is formed including TFT. However, QD-OLED adopts top emission method. A color filter is separately formed on the top glass substrate and the QD layer is patterned thereon. Therefore, QD-OLED requires higher investment cost than WRGB OLED.

The report describes that based on 8Generation 26K, the investment cost for QD-OLED is estimated to be US$ 1.1 billion, which is 1.03 times higher than WRGB OLED (US$ 1.07 billion). In contrast, the required investment cost to manufacture OLED by inkjet method, which JOLED is promoting commercialization, is projected as US$ 0.88 billion, which is to be about 80% of QD-OLED.

UBI research just issued 2018 2Q AMOLED Display Market Tracks

/in /by

UBI Research recently published “2Q18 AMOLED Display Market Tracks”, which includes market updates of the second quarter of 2018. The report covers OLED display panel makers’ investment status, OLED display market forecasts from 2018 to 2022, OLED demand and supply trends, and competitiveness analysis of OLED Smartphone business for Samsung Display and other OLED display panel makers.

The market update, published with the Excel spreadsheet, describes the production line status and the added line status through future investments of the 15 OLED display panel makers worldwide. Also, it describes not only the major OLED application market such as smart phones and TVs, but also the market forecast by country.

The demand for OLED mobile sets (including smart phones and smart watches) in the first quarter of 2018 dropped to 98 million units from 130 million units in the fourth quarter of last year, due to the lower-than-expected performance of the premium smartphone market, where Samsung Electronics’ Galaxy S series and Apple’s iPhone occupy most of the market. OLED mobile set market is to recover gradually until 3Q, when Apple’s new smartphone model is launched, and by the end of 2018, the demand is expected to recover as to the similar level of the same period of last year. In addition, Samsung Display is anticipated to have a positive impact on the recovery of the Smartphone market in the second half of the year by securing competitiveness by lowering the sales price of rigid OLED panel for mobile phone to about US$ 25 to compete with LCD in China.

Consumers' smartphone replacement cycle is getting longer due to the reason that there is no revolutionary change in the new model compared to the past, and the Smartphone penetration in most of the countries except for India, South America and Africa is reaching the limit. Accordingly, the outlook for the downturn is mostly forecasted in the recent smartphone market. There is a growing interest in technology and design to apply a different form factor to revive the market. In this regard, Samsung Electronics' foldable OLED smartphone, which is scheduled to be released later this year or early next year, is expected to create a new momentum. Attention is focused on whether a folding- type flexible display (Dynamic Flexible Display) will be succeeded as a new type of smartphone from the existing edge-type flexible display (Static Flexible Display).

 

UBI Research predicts that the OLED Smartphone market will grow from 430 million units in 2018 to 900 million units in 2022, and the market for foldable OLED Smartphone is to be from about 1million units in 2019 to 18million units in 2022. This reflects the expansion of OLED panel production lines by panel makers such as LG Display and BOE, besides Samsung Display. It will be updated as new applications are developed in future and the Smartphone market moves forward.

In OLED panel market, OLED panel for Smartphone still occupies 91% of the whole market. Samsung Display has accounted for 90% of total OLED panel market performance and LG Display is followed with about 7.8% share.

OLED TVs, which are continuously increasing in demand worldwide compared to the Smartphone market, are expected to be in short supply this year. LG Display, the only OLED TV panel supplier, will continue to invest in production for the next five years. With the recent approval of new production facility for OLED TV panel in Guangzhou, the full-scale equipment move-in is expected this year. In Paju P10 investment plan, it was confirmed that LG Display will invest in OLED TV panel production line instead of LCD line investment which was examined before. Thus, the OLED TV market is projected to grow to US $ 5.6 billion.

LG Display “Strategic direction is OLED. Uncompetitive LCD lines are planned to be switched.”

/in /by

In the 2Q earnings release conference call hosted on the 25th July, Kim Sang-don, LG Display CFO, said, “Looking back at the first half of 2018, the market was in a difficult situation due to the slump in prices, the traditional off-peak season and increased display supply from China. We expected the market conditions to be stabilized in the first half of this year from the bad market condition of the second half of last year, but it has continued to decline more rapidly and steeply. However, with starting the second half of 2018, it has been observing that the price is rising since July owing to upcoming favorable seasonality and customer restocking.”

“Although the market situation has changed favorably in the second half of the year, it is different from the past supply and demand cycle because of the uncertainty of forecasts. Moreover, the oversupply and asymmetric competition in the display market are unavoidable.” LG Display announced that it will maintain its conservative strategy in the second half of the year as the unpredictability is still high.

LG Display’s sales revenue in the second quarter of 2018 was KRW 5,611 billion, decreased by 15% compared to the second quarter of 2017. Operating loss in the second quarter of 2018 recorded KRW 228 billion. This compares with the operating loss of KRW 98 billion in the first quarter of 2018 and the operating profit of KRW 804 billion in the second quarter of 2017. The company suffered a large deficit due to a continued and steep decline in panel prices and lower demand in panels following the previous quarter. Although the shipment was increased by 2% QoQ, the selling price per area (m2) was decreased by 4%.

As a positive indicator, the TV panel price fell sharply, but the overall panel price decline was only 1% due to the competitive position of OLED panels. The market is anticipated to turn into positive situation in the third quarter, compared to the first half of the year, since panel shipments are expected to increase with the orders to restock the inventory.

LG Display, which is currently conducting both LCD and OLED business with small and medium sized panels and large area panels, mentioned clearly about its future strategic direction including the direction for the second half of the year as “concentrating on OLED business and focusing on high value of LCD business” in this conference call.

LG Display announced that it will focus more on differentiated LCD features and technologies in the IT sector such as narrow bezel, IPS borderless, and oxide technology, as well as high-value-added products such as larger-size TV panels and commercial displays, considering that a structural oversupply in panels and fierce competition among display makers are expected to continue down the road.

In addition, LG Display will achieve a turnaround to profit in the OLED TV sector in the third quarter of 2018. By making its final decision to invest in its Gen 10.5 OLED panel production line in Paju, Korea, and by starting mass production in the latter half of 2019 at its Gen 8.5 OLED production line now under construction in Guangzhou, China, LG Display will accelerate the expansion of the global large-size OLED market. Furthermore, additional production facilities for OLED 8.5 generation are known to be considered with the plan that the rationalization of LCDs during the year is also to be implemented although there was no direct mention of the timing and specific lines. For the plastic small and medium-sized OLED panel business, which is experiencing difficult times, compared to large area OLED, for which LG is expanding the production capacity in response to increasing demand, it said that they are preparing for future markets with the necessary strategic technologies with the emphasis of mobile and automotive markets. The E6-1 line, which has been mentioned as a production plant for Apple, is expected to begin mass production in the fourth quarter of this year, revealing the possibility of a possible supply of display to the iPhone OLED model in 2018. In addition, demand for OLED panels is increasing in the automobile market, and it is expected that full-scale business will start in the second half of next year. At the current order backlog, it is confirmed that OLED panels are in the late stage of about 10%. This means that much of the work has already been done. Finally, LG Display is well aware of the lack of funding and funding shortfalls over its competitors in relation to its future preparations. The company plans to reduce its capex by about 3trillion won by 2020, with a substantial portion of depreciation and amortization It is possible through internal working capital management and it plans to borrow the rest. LG Display confirmed that it has not reviewed the rights issue several times in the market, and LG Display has thoroughly prepared a variety of OLED portfolios, revealing its commitment to success by differentiating it from its competitors in the area of latecomers.

FlexiGO, developed the durability test equipment capable of accurate evaluation for foldable materials

/0 Comments/in /by

With the recent announcement that Samsung Electronics and Huawei are aiming to launch smart phones with foldable OLED, folder-type smartphones are drawing attention.

 Display companies are converting glass materials used in the existing substrates and cover windows into plastic materials. Consequently, the durability of plastic materials is becoming an important issue.

There are various types of durability tests, but the most typical durability inspection is the folding test. The folding test is an experiment that repeatedly bends and unfolds the foldable materials including plastic. Typically, a mechanical device is used for pivoting the rotating plate after fixing some part of the foldable material to the fixed plate and fixing the other remaining part to the rotating plate. However, in the conventional devices, the axis of foldable material is different with that of the rotating plate, the foldable material moves along the rotation path of the rotating plate, not the original rotation path of the material. Thus, there is a possibility that a tensile force acts on the folder material. To solve this problem, FlexiGO recently developed Foldy series, new durability test equipment to test foldable materials.

<FlexiGO’s folding test equipment, Source: flexigo.co.kr>

In addition to the conventional fixed plate and rotating plate, the Foldy series adds a motion controller that supports the fixed plate to move forward and backward for the foldable to be moved only through the original rotation path, so that no other stress is applied to the material. As a sliding device is mounted on the motion controller, the fixed plate moves forward and backward, and the rotating plate performs a rotary motion so that the foldable material can slide on the rotating plate.

The Foldy series includes micro vision, surface profiling, and colorimeter. Foldy-10 and Foldy-100 products can be adopted for the durability test in different test environments. In addition, it is possible to mount an additional inspection system, so it is expected that the accurate durability test of various accurate foldable materials is to be possible.

8K OLED TV, Can we see it in the second half of the year?

/0 Comments/in /by

 

Competition in the premium TV market is expected to be cutthroat.

The market share of OLED TV is on the rise in the premium TV market due to Sony’s entry into the OLED TV market and LG Electronics’ aggressive price cuts. However, LCD camp is responding with 8K high-resolution strategy, and attention is focused on whether it can prevent the rise of OLED in the premium TV market.

Sharp has already started selling 8K LCD TVs for the first time in the world since last year. Samsung Electronics showcased 8K TV at CES earlier this year, and will launch 8 K QLED (QD-LCD) products in the second half of the year. In the OLED camp, LG Display exhibited 88inch 8K OLED TV at CES, but the launch of 8K OLED TV in the second half is still unknown.

OLED TVs, which are currently in mass production, are based on bottom emission type. Thus, the light is emitted from the remaining portion of the pixel except the TFT region since the light is emitted through the TFT. Therefore, in the same size TV, as the resolution increases, the pixel size becomes smaller, but the area where the size of the TFT is reduced is limited, so that the area where the light is emitted becomes narrower. Consequently, in order to realize a high resolution at the same size, it is necessary to broaden the aperture ratio as much as possible or improve the performance of the emitting materials.

 

As a way of increasing the aperture ratio, there is a method of applying a top emission structure. Since the top emission structure emits light in the encapsulation direction, not the TFT direction, it can secure a wider aperture ratio than the bottom emission. However, there are pending problems that the encapsulation using opaque metal sheet should be changed to a transparent material and the color filter should be formed above the encapsulation with the change of the process.

The development of TADF blue and new blue materials is actively underway in the emitting material side.

The 88inch 8K OLED TV released by LG Display is made with a bottom emission structure and its ppi is about 100, which is about 20% higher than 80 ppi of the 55inch 4K currently being sold. When the pixel size is compared with the whole display size, the 55 inch 4K pixel is calculated to be about 40% wider than the 88inch 8k pixel.

In order to achieve the same level of brightness and lifetime as 55inch 4K, it is necessary to optimize the TFT design and improve the performance of the emitting materials to make up for the 40% decrease in pixel size. The industry is paying attention to whether the 8K OLED TV will be launched, with resolving above-mentioned issues, against the 8K LCD TV, which is expected to be released in the second half of the year.

The second half of 2018 just started, Chinese OLED panel makers are chasing Korea. Where are they?

/0 Comments/in /by


작성자: 오하나 (Analyst, hanaoh@ubiresearch.com)
The display industry has been in a state of confusion by the recent leaking of OLED display panel production technology into China.

As of 2018, five companies (BOE, Everdisplay, Tianma, Truly, and Visionox) have OLED production lines in China, among which only BOE has a line that can produce OLED displays (“Plastic OLED”) using plastic substrates, applied to the premium smart phones such as Samsung Galaxy and Apple’s iPhone. Other panel makers are building lines to produce plastic OLED displays targeting mass production this year and next year.

Monthly production capacity planned by Chinese panel makers by the end of 2020 is about 250K, which is more than the monthly production capacity of Samsung Display (about 180K). If China produces a similar level of panels through mass production, it is clear that Korea cannot defeat China in terms of production costs. The main application of the 6G plastic OLED display is a smart phone; however, the global Smartphone market has slowed down since 2015, especially in the premium Smartphone market, there seem no new markets. If mass applications such as smartphones are not developed, panel makers that do not have cost competitiveness will be hard to survive due to a large oversupply in the near-term and falling panel prices.

Korea is evaluated to have a considerable technical advantage since the production of plastic OLED displays requires a high level of technology and process know-how for the time. However, the industry expects that Chinese government’s support for the panel makers with the background of capital as part of the “China Manufacturing 2025” strategy, will shorten the technology gap quickly.

Chinese panel makers ahead of their mass production by 2019 are also reported to be more aggressively scouting Korea’s major OLED engineers. There are about 100 Korean OLED engineers in Chengdu (B7) plant that produces plastic OLED display of BOE. GVO is also known to have recently hired some important OLED engineers with high salaries. CSOT, which has been known to suffer difficulties from the initial research stage, seems to be expediting the construction of mobile OLED production line, employing Korean OLED engineers at major processes from last year. In addition, HKC, which is not a panel maker, is reported to have hired OLED engineers. This is interpreted as a work for investing in the OLED production line of HKC which has only LCD line, and HKC has recently been named as the merger of TIANMA OLED division.
As of 2018, there are no panel makers in China that can produce OLED display panels at the level produced by Korean panel makers. Although the production capacity and sales structure of Chinese panel makers are different from those of Korea, it is difficult to define yields on the same basis. However, the yield of BOE’s Chengdu (B7) plant, known as the mass production line, is still investigated as a single digit. Other panel makers also expect the product quality and yield problems to be difficult to be resolved by the first half of 2019 even if the mass production lines are launched within the year.

In order for the display industry, which contributes significantly to the Korean economy, to maintain its dominant position in the global display industry, it must maintain its competitiveness through various product development, production and sales strategies. Meanwhile, the size of the display industry needs to grow for the growth of the worldwide OLED industry. In order for Chinese panel makers to supply OLED panels with diverse applications, securing the yield might be the key.

LCD Smartphone is 4K era, what about OLED Smartphone?

/in /by

In the past MWC 2017, Sony unveiled the world’s first Smartphone with 4K LCD and it is scheduled to release the Xperia XZ2 Premium with 4K LCD on July 4. Attention is growing whether 4K resolution market is to be launched in earnest in smartphones.

TV market is already moving beyond the 4K to the 8K. Samsung Electronics and Sharp released new TVs with 8K resolution in the first half and Sony plans to release 8K TVs in the second half. LG Display also exhibited 88inch 8K OLED TV at CES 2018. As such, 8K TV is entering the premium TV market, and smart phones are expected to increase the number of products with 4K resolution in response to the higher resolution of TVs.

In the Smartphone, 4K has been implemented in LCD; however, in the case of OLED, QHD resolution is still dominant for the 4 consecutive years.

This is because there are many restrictions on the fine metal mask (FMM) technology that is being applied to OLED manufacturing. The thickness of FMM applied to the current production is about 20 ~ 30um. For 4K fabrication, the thickness should be as thin as 10um, but it is difficult for existing FMM manufacturing method.

As a result, FMM replacement technologies are being developed for high resolution implementation. Typical technologies under developing, include laser FMM patterning with laser, electroforming manufactured by electroplating method, a fine hybrid mask that is used to form a frame by electroplating on a film and pattern the film with a laser, and a surface source that realizes a high resolution by vertically setting the deposition incident angle.

Deposition technologies for high-resolution manufacturing at various exhibitions and conferences are being introduced. Depending on the availability for securing mass production, it is expected to see not only 4K OLED Smartphone, but also high-resolution AR and VR devices of RGB method.

[SID 2018] OLEDON, presented about X-mixing plane source deposition technology for AMOLED efficiency enhancement.

/in /by

In SID 2018, Hwang Chang-Hoon, CEO of OLEDON, announced a new plane source FMM deposition technology that can produce ultra-high resolution AMOLED of 2,250 ppi.

According to the announcement, the linear source currently applied to mass production has a problem of causing superimposition of fine adjacent patterns in a high resolution implementation due to a shadow distance of 3 μm. But Hwang said he succeeded in reducing the shadow distance of the patterns by 0.18 um using plane source, which is the smallest shadow distance ever introduced.

<Shadow effect comparison between current process and the process applied with the plane source, Source: OLEDON>

Hwang added that he developed ‘X-mixing’ technology in which the host and dopant thin films were separately deposited on the metal surface and then the host molecules and dopant molecules were automatically diffused through the plane evaporation to form the light emitting layer. Hwang commented, “It is not easy to control the composition of the dopant by using the linear source evaporation technology, which vaporizes the host material and the dopant material at the same time. However, since X-mixing technology can control the composition, it is possible to achieve a material utilization rate up to 4 times higher than the conventional method.”

China TCL will invest RMB 42.8 billion (US$ 6.71 billion) in Shenzhen to establish a factory for large-area OLED panel production. According to South China Morning Post, TCL recently announced that it will produce 90,000 units on the basis of 70-inch panel in the new production line of Gen 11 (3370 mm x 2940 mm) with the goal of mass production in March 2021 in the data submitted to the Shenzhen Stock Exchange. The main products are to be known as 65-inch and 75-inch OLED panels, and 65-inch, 70-inch and 75-inch display panels with 8K resolution.

TCL will form a partnership with the China Development Fund for the necessary financing and will set up a new production line at TCL’s semiconductor subsidiary with RMB 20.3 billion.

Large-area OLED to be produced by TCL is expected to adopt solution process RGB. At the ‘4th OLED Korea conference’ hosted by UBI Research in March, James Lee, deputy chief engineer of TCL mentioned about the development of next-generation premium TV with the screen size of 70-inch or more and 8K resolution, based on the solution process.

Lee said, “The price difference between OLED TV and premium LCD TV is estimated to be reduced to 1.4 times when the price of large-area OLED panel is lowered by the operation of LG Display’s Gen 10.5 plant in 2020. We are developing solution process technology for large area OLED and it will be applicable to Gen11 factory. ”

Gen 11 production line is capable of producing six sheets of 75-inch OLED panels, being able to achieve a yield three times higher than Gen 8.5 production line and a cutting efficiency of over 95%. In addition, it is possible to produce large-area OLED panels with a real RGB structure instead of the WRGB structure when solution process is applied. Based on this, TCL emphasized that the construction of the Gen 11 solution process OLED mass production line is essential. Meanwhile, TCL has jointly established JUHUA Printing Display Technology with Tianma, a Chinese company, in 2016 through CSOT, which is a subsidiary of TCL, and is continuously developing the inkjet printing process by a Gen 4.5 R&D pilot plant.

 

SID2018] Samsung display’s OLED technology, one step closer to full screen

/in /by

At the SID2018 exhibition in Los Angeles, a new concept OLED with no front speakers on the Smartphone was introduced.

Samsung Display’s new “Sound on display” removes the speaker at the top of the smart phone. Instead, it has a piezo electric actuator on the back of the panel that can turn the electrical signal into vibration. This is the mechanism by which the actuator vibrates the OLED panel to produce sound. It is the same method as LG Display’s “Crystal sound OLED”.

When this technology is utilized, the speaker can be removed from the front of the smart phone, resulting in a wider display area. Following the trend that the home button is embedded in the display, OLED will continue to evolve in the direction that the speaker is also embedded in the display.

Foldable OLED device is nearing commercialization. What are the technical challenges to be solved?

/in /by

Attentions are growing for the foldable smartphone since it can provide a wider screen and higher resolution than the display of conventional smartphones, while maintaining the portability of the smartphone. The foldable smartphone is a smartphone when folded, and it becomes a tablet PC when it is unfolded. Following Samsung Electronics, Huawei is also aiming to launch a smartphone with a foldable display this year.

Yi Choong-Hoon, president of UBI Research, said, “Ideal foldable displays require such kind of reliability that there is no problem even with more than 300,000 times folding at the bending radius of 1R or less. For this, some changes or innovations are needed in the material and structure of the display.

In the ‘2018 OLED Component & Material Report’ published by UBI Research on May 21, 2018, the key issues and development trends for foldable OLED display with a bending radius of 1R are described together with the classified contents of structural change to secure reliability at thickness reduction and alternative material development.

<Samsung Galaxy J6(2018), Source: WinFuture>

The Galaxy J6 (2018) is expected to have 5.6-inch rigid OLED with FHD + (2220 x 1080) resolution. Both the Galaxy A6 series and the Galaxy J6 are expected to be launched around the end of May.

Recently, the demand for rigid OLED for smartphone market has decreased due to the introduction of full screen LCD as well as LCD adoption in low-priced smartphones. Consequently, the utilization rate of rigid OLED mass production line has also decreased. According to UBI Research, rigid OLED shipments rose steadily from 2014 to 2016, but 290 million units were shipped in 2017, 8% down from the previous year.

However, the full screen rigid OLED, which was launched in the second half of 2017, started to be adopted in the VIVO X20 and Galaxy A8, and has been expanded to be applied to a number of smartphones such as the Galaxy A6 series and Galaxy J6. As the utilization rate of rigid OLED mass production lines is expected to normalize from the second half of this year, attention is growing whether rigid OLED market will be rebounded again.

BLUE OLED, is rapidly emerging as a competitor of WRGB OLED

/in /by

In the premium TV market, the share of OLED TVs is steadily increasing, and the price gap with LCD is gradually decreasing. As a result, LCD TV (QD-LCD TV) companies using quantum dot technology are sluggish in the premium TV market.

OLED TV uses white OLED and OLED panel with color filter (hereafter referred to as WRGB OLED), which is mass-produced only by LG Display.

Samsung Display is known to actively develop blue OLED + QDCF (blue OLED), which is one of the technologies to compete with WRGB OLED in the premium TV market.

UBI Research predicted that Samsung Display would implement blue OLED + QDCF with top emission method and it would be more advantageous to implement 8K and BT 2020 than WRGB in its ‘2018 OLED Material Industry Report’ published on April 18.

<Expected stack structure for Blue OLED, 2stack (left), 3stack (right), 2018 AMOLED emitting materials Report, UBI Research>

8K and BT2020 are to be adopted for the premium TVs. Also, the development of blue materials is expected to be aggressively progressed according to Samsung Display’s development of blue OLED. The blue material currently used in OLED is a fluorescent material that is insufficient in the efficiency and lifetime than phosphorescent material used in red and green. Blue phosphorescent materials have been developed continuously but they have not been applied to mass production due to the scarcity of materials and technical barriers. Therefore, blue fluorescent materials are stacked two or more times to improve efficiency and lifetime for large area OLED, and blue OLED is expected to use more than 2 stack structure.

 

With this trend, the market for blue emitting materials is expected to continue to grow. In 2017, blue materials (host and dopant) formed market of US$ 70 million.  According to the 2018 AMOLED emitting material market track published by UBI Research, blue material is expected to grow at an average annual rate of 32% by 2022 and reach US $ 272 million sales.

Foldable smart phone, can it absorb tablet PC market?

/in /by

“If foldable Smartphone is launched and commercialized in earnest, the high-priced tablet PC market is likely to disappear.”

Choong-hoon Yi, president of UBI Research, said in ‘the Latest OLED Technology Trends Seminar’ held at COEX in Seoul on the 26th April, 2018.

He also mentioned “The foldable smart phone is expected to be implemented as a 5.2 inch display with a 7.2 inch display folded in half. In addition, a bar-type display is to be added to the outside to check time and other information.”

Yi analyzed, “Foldable Smartphone can provide a momentum to revitalize the stagnant Smartphone market, and a positive aspect that can induce new investments to secure a sufficient number of panels due to the increase in the display screen size.”.

“If foldable smartphones are launched and commercialized, there is a possibility that the expensive tablet PC market will be disappeared. Foldable Smartphone can bring the tablet PC market which is being led by Apple.”He added.

Yi then predicted that foldable smart phones would implement 4K since their screen size is larger than normal smart phones. “OLED smart phones, which currently remain in QHD resolution, are expected to be difficult to implement it in five years due to the problems in masks, wiring widths and exposure systems; however, foldable smart phones are more free from these problems.” He said.

Finally, Yi pointed out the market success factors of the foldable smart phone as pioneering the Smartphone market for over $ 1,000, development of dedicated applications/contents and early establishment of 5G communication technology for data transmission such as video streaming.

Meanwhile, he estimated that OLED panels for foldable smartphones would be shipped to 100 thousand units in 2018, and 2.83 million units would be shipped in 2022.

In order to accelerate the mass production of solution processed OLED?

/in /by

At the latest OLED technology trends seminar organized by UBI Research in Seoul COEX on April 26th, professor Seo presented about the status of solution processed OLED for large-area TV production.

Professor Seo emphasized that there are four technical challenges to advance the mass production of solution processed OLED.

The first challenge is the development of materials that can form stable and flat thin films. When the emitting material for solution process is applied, the solvent causes a convection phenomenon due to solubility and boiling point. Therefore, it is difficult to make a flat film because the speed at which the solvent flows is different for each region.

The second is the development of cross linked HTL materials. Emitting material companies are mixing cross-linking agents into HTL materials for solution process to solve intermixing problems between layers. However, a pinhole is formed due to a cross linking reaction with the surrounding small molecular materials when crosslinked materials in small molecule type are used. This kind of pinhole lowers the uniformity of the thin film, and therefore it is necessary to develop crosslinked HTL materials that can improve the reproducibility and lifetime of OLED in solution process.

The third is the jetting condition. He proposed a jetting condition that can minimize the volume deviation of the emitting material for solution process every head since it is necessary to drop the emitting material for solution process of less than 4 pl to the desired position in the size of 20-50 um to realize 8K. Lastly, he commented that it is required to optimize the drying process of solvent. UBI Research described that the solution OLED process has a simple (5 layer) structure and high material utilization efficiency compared to the conventional deposition process. In addition, it is possible to manufacture large-area OLED with RGB structure without the division of mother glass at Gen8 or higher. When major panel makers adopt solution process, it is available to reduce the manufacturing cost of OLED due to the decrease of equipment and equipment scale as well as material cost and labor cost reduction. According to the 2018 Annual OLED Display Industry Report and 2018 Emitting material Industry Report published by UBI research, solution processed OLED is to be mass produced from 2019 in earnest, and the shipment is expected to be 0.2 million units in 2019 and 9.2 million units in 2022. Accordingly, the emitting material market for solution process is estimated to grow to US$ 110 million in 2022 from US$ 9 million in 2019.

Micro LED TV, is the price competitive compared to OLED TV?

/in /by

“It needs to consider how to resolve the price competitiveness compared to other displays, such as OLED, before Micro LED is to be applied to the big screen TVs of 60 inches and 70 inches in future.”

Moon Dae-Gyu, professor of Soonchunhyang University, mentioned as above while explaining the micro LED technology at the ‘latest OLED technology trends seminar’ organized by UBI Research in Seoul COEX on April 26th, 2018.

“Micro LED is attracting attention as a technology capable of realizing a high resolution display of 1,000 ppi or more. Since micro LEDs are individually obtained from a LED wafer by the photo process, they are not affected by the size and shape of a substrate, and have the merits that the advantages of existing LED such as luminance, lifetime and low power consumption, can be applied as they are.” professor Moon added.

In addition, it is expected to be a good environment to show the advantages of micro LED in the field where power consumption is very important, such as wearable appliances. He also predicted that it is possible to implement display in no tile form in very large display area such as public display and digital wall, which might be easy segments for micro LED to enter.

However, regarding the mass production of micro LED TV, which is becoming a recent issue, Moon said, “In order to implement 4K, 24.8 million LED chips (with a size of 10 μm/chip) are required. At the 4 inch wafer, which is currently being commercialized, 4K panels can be produced twice only. Thus, it is doubtful whether micro LED is competitive compared to LCD and OLED in terms of mass production.”

Commenting about TFT uniformity and pixel uniformity of the micro LED, he mentioned “TFT uniformity can be sufficiently compensated by the compensation circuit that is currently applied to OLED, but it should be considered how to solve the color imbalance problem.”

Micro LED TV, which was introduced by Samsung Electronics in CES 2018, and received a lot of attentions at the time, but it was disagreed about commercialization. In particular, Kang In-Byung, CTO of LG Display, pointed out, “About 25 million LEDs are needed to realize 4K micro LED TV. Even if 1 LED is 1 Korean Won, the cost might be 25 million. And when the circuits and boards are added, it would be a huge price.”

Display sales QoQ and YoY are -32.6% and 3.4%, respectively, and operating profit QoQ and YoY are -70.9% and -68.5%, respectively. OLED sales accounted for 70% of its total display sales. According to Samsung Electronics, the profitability of OLED segment in the first quarter of 2018 declined due to a decrease in demand from major customers and intensified competition with LTPS LCD for rigid OLED. In spite of the downturn in sales due to seasonal weakness and the decline in panel prices, LCD division achieved similar profitability as the previous quarter, thanks to the increased sales portion of high value-added products such as large-size and UHD and continuous cost reductions.

 

OLED demand is expected to continue to decline in the second quarter of 2018, and Samsung Electronics plans to expand its customer base while striving to secure competitiveness through cost reduction and production efficiency improvement. Although LCD segment is also expected to continue to show oversupply in 2Q 2018 due to the launch of new LCD lines, Samsung Electronics plans to secure profitability through timely development of high value-added and differentiated products, and cost reduction activities. Samsung Electronics said the demand of OLED panels for mobile devices is anticipated to gradually recover in the second half of 2018, while flexible products are expected to be the main focus of premium products. Also it emphasized that Samsung will expand its market share by expanding customer base through new technologies and new products, and strengthening cost competitiveness, together with technology differentiation with LCD and enhancement of new applications capacity. For the LCD segment, uncertainties are to be increased as Chinese panel makers continue to expand production volumes with the fierce competitions competition among companies. Samsung mentioned that it will continue to focus on differentiating with the large and high-end premium products and strengthening strategic partnerships with major customers to secure profitability.  In the first quarter of 2018, Samsung Electronics sold 86 million mobile phones and 5 million tablets. The sales for mobile phone sales in Q2 2018 are expected to decline compared to the previous quarter, and tablet sales are expected to maintain the level of the previous quarter.

Total investment of Samsung Electronics in the first quarter of 2018 was 8.6 trillion won, of which 0.8 trillion won was invested in the display. Although the investment plan for this year has not been finalized yet, it is expected to decline from 2017 due to the rapid expansion of flexible OLED production, new technology development, and facility investment to prepare for market growth last year. Choi Kwon-Young, Vice President of Samsung Display said, “Currently, the mass production of A4 line is ready for operation in accordance with the agreed schedule with the customer. And A3 line is trying to minimize the drop in operation rate.” He continued “We are under development by focusing on Quantum dot and 8K technologies to meet customer needs for big screen TV market. Also we are interested in various next-generation display technologies including micro LED.”

Samsung Electronics has continued research and development for the commercialization of foldable phone, and now it is working with various companies to improve the product’s completeness.” Samsung said. Further, it added “We are focusing on improving the completeness of the product so that it can give real value to the consumers rather than simply launching it for the first time in the world. If the parts performance and durability for the implementation of the foldable phone are more stabilized, and various use cases are found with the emergence of new form factor, we will disclose separately the timing of its commercialization.”

Can BLUE OLED be used for OLED TV?

Samsung Display selected blue OLED + QDCF (blue OLED) as next generation display technology following LCD TV, and started the necessary development.

Blue OLED is a technology, in which blue light emitted from blue OLED passes through a quantum dot color filter to represent red and green colors (b). The WRGB OLED used in OLED TV is a method in which white light passes through a color filter and implements RGB colors (a).

The ‘2018 OLED Materials Industry Report’ published by UBI Research on April 18 describes whether blue OLED, which Samsung Display has started to develop, can become TV OLED panels. The expected development direction and performance (efficiency and lifetime) of blue OLED + QDCF are analyzed. In particular, current status and development trends (fluorescence, phosphorescence, TADF) of blue emitting material, which is the core material of blue OLED, are covered.

Since blue OLED of Samsung Display is top emission type, the aperture ratio is increased by about 70% compared to the bottom emission, which emits light in the TFT direction, so that 8K resolution and high brightness are realized better than the conventional WRGB OLED. In addition, it is expected to reach BT. 2020, the UHD color standard, which was established by the International Telecommunication Union (ITU) in 2012, using QD material with high color reproduction rate as color filter.

In the future premium TV market, 8K and BT. 2020 are necessary conditions for display. WRGB OLED is also being actively developed to implement 8K and BT2020. Attention is focused on the impact of the development of blue OLED in the premium TV market led by WRGB OLED.

In addition, the report analyzes the market status and development trends of the related companies, including overall technology development directions and key issues for new materials such as soluble OLED materials and near IR materials.

LG Display 88-inch 8K OLED TV was released to the public through CITE held in Shenzhen, China

/in /by

CITE, an electronics trade show held in China on April 10, 2018, had a relatively lukewarm atmosphere with significantly fewer visitors than last year. It seems to have been influenced by the lack of special IT issues, compared to last year when it was crowded with the attention of many general visitors.

Especially, there were no new products on the TV appliance side. Most of the exhibitors displayed the same products as those of last year or 2018 CES. On the other hand, LG Display unveiled its 88-inch 8K OLED TV, which had been hiding in its own booth, at the front of the booth. CSOT also showcased OLED displays made with printing technology that had been publicized several times during several conferences. 8K OLED TV is to be the future of the high-end premium TV as it clearly shows the advantages of OLED display such as contrast ratio, sharp image quality and color reproduction through large screen. CSOT’s 31-inch display is meaningful because it exhibited the results of CSOT’s printing OLED technology development. It is preparing for a new investment of about 20K TV line next year. The exhibited product was manufactured by using top emission Ink-jet printing technology to oxide TFT. The peak brightness is 150 nit at 144 ppi.

Changes in OLED panel market for smartphones

/in /by

According to the ‘2018 1Q AMOLED Display Market Track’ published by UBI Research, OLED panel shipments for smartphones are projected to grow at an annual average growth rate of 15.8%, from 450 million units in 2018 to 850 million units by 2022. This is a 9.6% decline from the CAGR 25.4% expected in the fourth quarter of 2017.

<Shipment forecast of OLED panel for smartphones >

The reason shipment forecast of OLED panels for smartphones is declined compared with 4Q,2017 is because smartphone trends have been reflected recently. The smartphone market is sluggish due to the prolonged replacement period of smartphones and the lack of new technology. In addition, the average size of smartphones has enlarged faster than expected, and the size of smartphones is expected to increase gradually with the anticipation for the launch of foldable OLEDs, leading to a slowdown in the shipment growth.

For flexible OLED, ASPs have risen due to the lack of supply, caused by mainly dependent on Samsung Display, and Chinese set makers are burdened by its high prices. As low-priced full-screen LCDs are emerging, it is forecasted that demand for rigid OLEDs will decline since Chinese set makers are adopting more LCDs than OLEDs in rigid smartphones.

Panel makers in Korea and China have aggressively invested in the Gen6 OLED line in 2016 and 2017. Starting this year, however, they are reviewing the investment and operation time frame of mass production lines, with looking into the smartphone demand. As OLED panels for smartphones account for more than 90% of the total OLED panel market, it is an important factor for the investment flow of panel makers.

Meanwhile, ‘2018 1Q AMOLED Display Market Track’ is based on the market performance data and projected system that UBI Research has accumulated over 15 years. It consists of 8 (eight) modules in total: Panel cost analysis, Market forecast, Supply and demand analysis, Market performance (sales), Competitiveness analysis of panel makers, ASP, Supply chain analysis and investment & Mass production line status.

In addition, it introduces various application possibilities while showcasing a 77-inch UHD wallpapers OLED, which can be closely adhered to the wall to enhance the interior effect of the living room, and a round shaped pillar product consisting of six 77-inch UHD OLEDs.

Meanwhile, LG Display showed OLED lighting in China for the first time in this exhibition. OLED lighting is environmentally friendly because it consumes less power and heat than conventional lightings, and is a premium light source that minimizes eye fatigue by being close to natural light. It is free to implement curved surfaces like OLED displays, and provide consistent light as a unique surface light source. OLED lighting panels are available in various shapes: circular, square, rectangular, and others.

Saying “OLEDs with the potential to expand into a variety of applications will provide differentiated value to consumers,” Yeo Sang-Duk, CMO (chief marketing officer) of LG Display commented “We will continue to lead the OLED market with Chinese customers in the Chinese market where the acceptance of new technologies and new products is the fastest in the world.”

According to the ‘2018 OLED Display Annual Industry Report’ published by UBI Research in February, the OLED market is predicted to grow at an annual average of 22% from US$35.7 billion in 2018 to US$ 78.2 billion in 2022.

QD-OLED TV, is it to be the next generation premium TV?

/in /by

Samsung Electronics is currently occupying the premium TV market with QD-LCD TVs, which use ‘PL-QD (photoluminescence quantum dot) technology’. This technology has a mechanism in which the material stimulated by external light re-emits light.

The operating profit of the consumer electronics division (CE), which controls QD-LCD TVs, fell more than Korean won 1 trillion in last year and the operating profit ratio was only 3.6%.

On the other hand, LG Electronics’ HE business division achieved a record operating profit of Korean won 1,566.7 billion and an operating margin of 8.1% through OLED TV. Sony also turned its operating profit into a surplus by quickly taking over the premium TV market with OLED TV.

OLED TV has had a positive effect in driving corporate sales growth.

Samsung Electronics has been developing EL-QLED, with EL-QD (electroluminescence quantum dot) technology, to increase its market share in the premium TV market. However, efficacy, lifetime and mass production technology of quantum dot, which is the material of QLED, is not yet secured.

Recently, QD-OLED TV technology, which uses blue OLED as a light source and that implements red and green colors through a quantum dot color filter (QDCF), is attracting attention.

<Expected structure for QD-OLED, Source: Samsung Display Blog>

By using QDCF, it is possible to easily make desired colors by adjusting the size of the QD material and improve the color reproduction rate. This is because the color gamut is enlarged to BT2020, so it is close to natural color and it is possible to deliver vivid picture quality more clearly. In addition, QD-OLED TV has a top emission structure, which makes it easy to secure the aperture ratio, thereby improving resolution and screen uniformity.

However, in QD-OLED TV, there are various problems to be solved such as lifetime and efficiency of blue OLED, and technology of ink-jet printing process. Given that the industry is still in the early stages of reviewing the business possibility, QD-OLED TVs are expected to go into mass production after 2020.

Attention is focused on the QD-OLED TV’s entry into the premium TV market and its impact.

Google-LG Display to show OLED for 1443ppi VR device for the first time in the world

/in /by

Google and LG Display are planned to unveil OLED displays for ultra-high-resolution VR devices with the world’s first 1443 ppi at SID 2018 in Los Angeles in May.

<OLED for VR devices, which Google and LG Display will unveil, Source: Android Police>

According to the Verge, the OLED for VR devices released at SID 2018 has a resolution of 5657 x 3182 (1443 ppi) with 4.3 inches in size.

The resolution is 2.4 times higher than Samsung Electronics’ Odyssey (model no. XQ800ZAA-HC1KR), which is currently known to have the highest resolution of 1400 x 1600 (607ppi), among VR devices supporting HMD. Also, it is about 1.9 times higher than the OLED for VR devices (1824 x 1824, 806 ppi) displayed at iMiD 2017 in August, 2017.

Since the distance between the eyes and the display is very short, a VR device has a ‘side door effect’ phenomenon in which the pixel patterns of the display are shown in a lattice form when the resolution is low. In addition, low resolution increases the fatigue of eyes, and it becomes a factor that deteriorates reality due to inaccurate graphic information (image distortion). Accordingly, the related companies are developing panels for VR devices with high resolution that can compensate them.

<VR screen comparison according to resolution, Source: speedvr.co.uk>

OLEDs for VR devices to be exhibited by Google and LG Display are the best in the world at the refresh rate (120Hz), too.

Higher refresh rates can display more screen frames within the same time period to minimize the nausea phenomenon and increase immersion by showing more natural images. Accordingly, Oculus VR, HTC, and Korea Information and Communications Technology Association have prescribed the refresh rate of the VR display as 90 Hz or more, and SONY defined as 120 Hz.

According to the ‘Display Market Report for AR and VR’ published by UBI Research in July 2017, the VR devices launched from 2014 to 2016 have a refresh rate of about 65 Hz for LCDs and about 86 Hz for OLEDs. In order to implement a high refresh rate, OLEDs with higher response speeds and lower power consumption than LCDs are more advantageous.

Next-generation emitting materials, development is under way

/in /by

At the 4th OLED KOREA CONFERENCE, Kyulux and CYNORA, the leaders in the development of next generation emitting materials, announced the results of research and future development directions.

Junji Adachi, CEO of Kyulux, said, “We are developing Hyperfluorescence in the form of adding a TADF dopant to the existing fluorescent host and dopant.” He also emphasized that the emission FWHM (full width at half maximum) of Hyperfluorescence is about 35% of that of TADF, and the luminance is about twice as high, and this material can solve the drawbacks of TADF (wide FWHM and low luminance) at the same time.

The latest Hyperfluorescence, which Jundi Arachi introduced, has efficiencies of red 28 cd /A, yellow 43 cd/A, green 81 cd / A, and life span is 10,000 hours, 62,000 hours, and 48,000 hours based on LT50 (1000nit) respectively. The color coordinates are red (0.64, 0.36), yellow (0.46, 0.52), and green (0.28, 0.65).

Andreas Haldi, CYNORA’s Chief Marketing Officer of CYNORA, said that the blue TADF emitter developed by CYNORA now has a color coordinate of 0.16, EQE of 24% and 10-hour lifetime (LT97 @ 700nit).

The performance is more than twice as efficient as the blue material currently used in OLEDs, and the color coordinates (0.10) are similar but the lifespan is short. He added that the Blue TADF emitter is scheduled to be developed within 2018 and will be available for mass production in 2019.

He also mentioned that the manufacturing cost is reduced and the power consumption is reduced, thereby minimizing battery consumption if blue TADF emitters with high efficiency are used instead of conventional low-efficiency blue materials. At the same time, it is expected to be able to improve the resolution of OLEDs and be applied to large-scale vacuum processing lines of major panel makers.
According to CYNORA, next step is to develop green TADF emitters (2019) and red emitters (2020) after finishing the development of blue TADF emitters (2018). Thus, it might be completed ‘RGB TADF emitter development’ by 2020.

“OLEDs will be installed on the ceilings and walls of planes to provide customers with a variety of images. It is expected that stars will shine in the ceiling at night and clear blue skies during the day time inside the future airplane.”

Dr. Julian Chang, associate tech fellow of Boeing, presented various advantages of OLED to be applied to the inside of planes in future at the ‘2018 OLED Korea conference’ hosted by UBI Research on March 7~8.

Explaining “OLEDs are capable of full black implementation and excellent color reproduction”, Dr. Julian said that “We can provide customers with realistic blue skies and night skies.” “The planes have a lot of curved surfaces, so easy-to-implement OLEDs have advantages over other displays.”

He also emphasized the advantages of OLED which are helpful to provide information, without limit of viewing angle, to customers and crews who need a lot of information in a narrow space, reduce the blue light that interferes with sleeping, and reduce fuel consumption and carbon dioxide with lower power consumption than LED.
On the other hand, he commented that it is necessary to improve the maximum luminance, reduce the burn-in phenomenon, satisfy FAA regulations, and facilitate easy installation and repair in order for OLED to enter the airplane industry.
Today, OLEDs are expanding beyond mobile devices and premium TVs into automotive and wearable markets. Attention is growing whether customers are given a new experience to taste the realistic sky as OLED is applied to the interior of the plane.

OLED TV continuing to evolve

/in /by

At the ‘4th 2018 OLED Korea Conference’ hosted by UBI research on March 7-8, Dr. Han Chang-Wook, Chief Research Fellow of LG Display, made a presentation for the development process of OLED TVs and emphasized the image quality of OLED, design flexibility and expandability.

At first, Dr. Han introduced three core technologies including TFT technology, OLED stack technology, and compensation circuit design applied to OLED TVs. He said, “We changed the TFT as top gate coplanar structure for UHD implementation in bottom gate TFT applied to FHD.” He also mentioned “We changed the WRGB OLED pixel structure from 2 stack structure to 3 stack structure to improve the luminance and color reproduction ratio, and designed the compensation circuit so that it does not affect the OLED even on 8K large screen.”

He commented, “Unlike LCDs that control pixels with local dimming, OLEDs have pixel dimming controls, which allows for full black representation and less halo effects”

Explaining that OLED allows greater design flexibility and expandability because of the self-illuminating properties that does not require backlight, he referred to the mirror display and transparent display applicable to indoors, and the world’s first 88 inch 8K OLED TV and 65 inch rollable OLED TV exhibited at CES 2018.

Dr. Han said “We expect large OLED panel production to be tripled, compared to 2016, with the expansion of production lines and yield improvement in 2018. In addition, the company will be able to ship over 6 million large area OLED panels by 2020 through the expansion of its Paju and Guangzhou plants.” He also announced that the company will increase continuously the production for OLED panels, which were 5% of the total display panels in 2016, by 40% by 2020.

According to the exhibitors, the company will try various strategies from this year and will not necessarily follow its competitors in launching new models. In terms of the overall model reorganization of the G series and the V series, it has decided to concentrate on the essence of the phone for the time being rather than making a big change. With regard to the V30S’s release, it is said that V30S is different from V30 in terms of taking bright and clear pictures in the dark place by improving the illumination including AI application to the camera modules, and the enhancement of the stereo system. Also, V30 users might be able to experience soon the same performance as V30S through software upgrade.

Though it was not revealed at this MWC exhibition, the new premium mobile model to be launched this year will adopt the ‘ ThinQ AI’. It was announced that the new model was released after the V30 in a separate private booth; however, the release time has not yet been confirmed.

Regarding 5G, which is one of the biggest trends in this exhibition, North America and other regions are rapidly moving, and LG Electronics has also been working hard on this inclusive of the development of foldable smart phone.

Unlike last year’s show with various watch models, LG Electronics’ MWC booth is a little reduced as it seems to prepare for the next. The V30S is the only OLED display product, and most of the exhibits highlighted the enhanced performances of the V30S, such as the experience of a Hi-Fi QUAD stereo system through wearing a headset and the experience of a camera’s Bright Mode in the darkroom. In addition, the K10 (K10, K10 + – 5.3 inch HD) series, which are entry level models, has been released through this exhibition.

2018 MWC – Sharing Samsung’s market retention strategy with S9 introduction

/in /by

The Mobile World Congress (MWC), which takes place every year in Barcelona, Spain, is well known for releasing new models of smart phone brands that year. This year, however, Samsung Electronics and most of the smart phone makers exhibited new line-ups that did not change much or were hard to change dramatically.

In particular, through a press conference held on Monday, February 26, 2018, Samsung Electronics shared some strategies about concerns that the smart phone market will be experiencing an overall shift in replacement cycles and that the growth rate will slow down gradually.

According to the company, the company will concentrate its strategy in three major directions. It plans to set up a global trading system that will compensate for the remaining price by returning the Galaxy S7 within two years of an implicit average replacement cycle or by returning a competitor’s phone, which might be helpful to secure new customers while preventing current customers escape. This is already done by Apple in a system called recycling.

Another strategy is to secure customer loyalty through experiential marketing that enables users to experience various functions of Galaxy Studios and Galaxy by inducing them to shorten replacement cycles through targeted marketing using customer data. Note 8 sales were slightly lower than originally target at 11 million units, but note series have steady B2B demand and fixed customers. Note 9 is largely defined and can only be described as trying to differentiate itself from other customers at this time. The S9, which was unveiled at the show, said it expects better results than the S8 with its timely sales plan.

The S9, a new model released through the MWC, focuses on camera functions, better Infiniti 5.8-inch displays, stereo sound and IoT-centered mobile phones, redesigned with a new dual aperture lens that powers an innovative low light camera, Super Slow-mo video capabilities and personalized AR Emoji. The exhibition response to date has been evaluated to be a better level than expected, and visitors at the exhibition hall were enjoying the experience of emoticonizing themselves.

In addition, a variety of OLED models including the A8 model (5.6-inch FHD +), A8 + (6.0-inch FHD +), Galaxy Fit 2 Pro and Gear sports, were exhibited.

Galaxy S9 – Curious about Samsung’s strategy to launch Foldable Phone

/in /by

Interests in Galaxy S9 and Note 9, which will be released soon, are growing. There are a lot of people who want to figure out in advance the features of Foldable Phone, which Samsung announced to be launched within this year, through Galaxy S9 and Note9. However, it is impossible to predict the specifications of the Foldable Phone with the contents that have been opened so far.

In general, Galaxy S9 does not seem to be much different, compared to the previous S8. The front fingerprint sensor, which has been anticipated since last year, may not apply, and it seems to adopt iris recognition and fingerprint sensor at the back side. Unlike the S8, which was noticed in the name of Infinity Display, it will not expect much different concept in the design part. The CPU will be equipped with Samsung’s Exynos 9810 chip, except for the US model.

So what is the strategy of the Galaxy series this year? Some say that iPhoneX’s sales volume is a failure, but if you consider adding iPhoneX to the 3-model lineup in the new 2-model lineup, Apple’s overall performance is a success. In the meantime, there seems to require a new strategy for the Galaxy flagship model, which was dominated by superior image quality with adopting OLED display.  The Galaxy S9 appears to have little change, except for a slight improvement in performance. Therefore, it is curious whether it might be Samsung’s planned intention to concentrate on launching the Foldable Phone.

Samsung Electronics will unveil Galaxy S9, its next-generation strategic smartphone, at MWC 2018, held in Barcelona, Spain on February 25. Galaxy S9 is anticipated to be equipped with various features such as dual cameras for the first time at the Galaxy S series and intelligent scanning, so expectations for the Galaxy S9 are rising.

The Galaxy S series continued to increase in ppi and display area (DA), starting with the ‘Galaxy S’ in 2010. The first Galaxy S was introduced with 4 inch WVGA rigid OLED, with 235 ppi and 58% DA. For Galaxy S6 which is the first Galaxy S series adopted with flexible OLED, its ppi became more than doubled and DA was 70.7% increased by 22%, compared to Galaxy S.

<Evolution in ppi and DA for Galaxy S series>

Launched in 2017, the Galaxy S8 first extended the DA to 83.6% by removing the home button and minimizing the bezel for the first time on the OLED smart phone. Through these changes, Samsung Electronics introduced a full-screen OLED display.

According to the industry experts, Samsung Electronics is expected to implement full-screen by expanding DA to 93% with 5.8-inch OLED in Galaxy S9 to be unveiled at MWC 2018.

As the full-screen OLED smart phone has become very popular with consumers, Apple, LG, VIVO and Oppo have started to incorporate full-screen OLED into their flagship models. As a result, smart phones with full-screen OLEDs are expected to become main stream this year.

Meanwhile, it is estimated that 230 million units of flexible OLED panels will be shipped in 2018 according to the recently published ‘2018 OLED Panel Industry Report’. The size of OLEDs is expected to increase steadily for implementation of full screen. Moreover, the development direction for full screen is to be from current full screen or notch type (form of making holes in speaker and camera functions) to the form of real full-screen displays, in which they (speaker and camera parts) are not visible on the front display.

Now, display is changing in order to facilitate and enable the “Connectedness” of these electronic devices. If display was simply recognized as image projection in the past, now it becomes a tool of “Communications”. “Connected” without display seems incomplete as it recognizes the user through display and extend from information output to information selection and recognition of correct information.
