[IMID 2022] SEL Develops 5,291ppi Micro OLED Display Integrating Si CMOS and OSFET

At IMID 2022 held from August 24th to the 26th, Semiconductor Energy Laboratory (SEL) announced that it has developed a 5,291ppi micro OLED display for AR/VR that integrates Si CMOS and OSFET.

OLED, OS, Si structure/SEL

OLED, OS, Si structure/SEL

According to SEL’sannouncement, two problems arise when manufacturing an OLED display with high pixel density by integrating the existing Si FET. The first is that the source/gate drivers are located outside the display area, which increases the bezel width. A thin bezel width is a prerequisite for a decent AR/VR device size. The second issue is the high mobility of Si FETs and the balance between pixels. In order to apply Si FET to Micro OLED, it is necessary to reduce the transistor size while suppressing the increase in current.

In order to solve these problems, SEL announced that it has manufactured an OLED micro-display prototype that integrates Si CMOS and OSFET. SEL states that, “The mobility of OSFETs is not as high as Si FETs, but it is sufficient to drive OLED devices. Through the OLED/OS/Si structure in which OS (OSFET) and OLED are combined on CMOS, the width of the bezel area can be reduced by up to 40%. In addition, in the characteristic evaluation of OSFETs, it was possible to implement deep black and drive a low rate of fire, and the good distribution in a channel length of 200 nm and a breakdown voltage of about 20 V made it suitable for high voltage OLED driving of white-tandem OLED devices.”

The size of the 5,291ppi micro OLED display announced by SEL is 0.51 inches, the resolution is 1920×1920, and the pixel size is 4.8×4.8 μm. The backplane is a combined structure of 130 nm Si FET and 60 nm OSFET.

The next full-screen display trend is the under-display camera

Reporter : Daejeong Yoon

Since Samsung’s Galaxy S8 and Apple’s iPhone X launch, smartphones with the Home button removed have become a trend in the smartphone market.

Due to the nature of smartphones that cannot grow indefinitely, display sizes with a large proportion within limited smartphone sizes are directly related to the competitiveness of smartphone set makers.

Samsung’s Galaxy S10, which was recently released, attracted great attention with its flexible OLED with HIAA (hole in active area) technology. Notch or HIAA designs, however, can still interfere with video viewing and gaming because camera lenses occupy a small portion of the display.

That is why a number of panel makers are developing under display camera technology for a full-screen display.

Under display camera technology allows the front camera to be placed behind the display for a full-screen display. Oppo unveiled the first smartphone with the technology at MWC China 2019, and BOE and Visionox also anticipated that under-display cameras will become the next trend in smartphones at CIOC 2019.

It is expected that screen, camera module, and algorithmic technologies will all be specially designed to implement under display camera technology. Specifically, the technology to make the pixel near the camera at low resolution to secure transmittance, to mount a CMOS image sensor of a larger pixel size than the existing, and to apply algorithm technology to improve the picture quality.

The trend of full-screen smartphones, which began in 2017, is paying attention to whether full-screen smartphones will bloom with the technology of under-display cameras since 2020.

[SID Vehicle Display 2019] OLED is optimal for side mirror replacement display

In October 2018, Samsung Display received a lot of attention by supplying OLED for side mirror replacement to e-Tron of Audi, a global automaker. e-Tron has a camera installed in the side of the existing side mirror, and the driver can check the surroundings through the OLED installed in the vehicle.

Mirrorless cars were discussed at the SID Vehicle Display 2019 panel discussion in September 2019.

Drew Harbach pointed out that “existing side mirrors may have the effect of glare in tunnel-like spaces.” “The cameras and displays can be reduced to provide a better night view.”

He mentioned that the resolution of the display is important, of course, but the contrast and FOV are also very important factors. He also emphasized that the contrast ratio should be very high so that objects can be seen under any environmental conditions.

The high contrast ratio is a very helpful factor in recognizing objects not only in dark nights but also under the strong sunlight of the day.

Panelists mentioned the various displays such as LCD, OLED, micro LED, etc., but OLED is the only display with high contrast ratio and wide viewing angle in the environment where mass production is possible. In addition, OLED has a very fast response time, which is widely used in VR devices and professional monitors where image quality is very important.

OLEDs are mentioned as potential candidates for side-mirror displays and are expected to be used in internal displays, such as clusters and CIDs (center information displays). Korean and Chinese panel makers are actively developing automotive OLEDs, and Samsung Display has forecast that automotive OLED panels will increase to about 3 million by 2022.

[IFA2019] Sony’s OLED TV Evolving from Year to Year

Sony, which is driving the OLED TV market with LG Electronics, is exhibiting OLED TVs with new features at CES and IFA after the first display of OLED TVs.

The OLED TV displayed at Sony’s booth, which was first opened on Media Day of IFA2019, did not show a woofer. Using surface acoustic technology to produce sound from the screen, Sony showcased the CES2019’s model with four actuators on the back of the OLED panel and a woofer speaker as the rear stand. However, the woofers disappeared in IFA2019.

According to exhibition officials, the secret is that the panel is arranged with six actuators, three rows of two behind the panel, so that sound can be displayed on the screen from low to high.

[SID2019] What material is better for cover windows of foldable OLED? colorless PI or UTG?

Since Royole introduced ‘FlexPai’, a foldable OLED phone, Samsung Electronics and Huawei have also launched Foldable OLED phones, attracting great interest from the industry and the public.

The biggest change of the foldable OLED phone currently being commercialized or under preparation is that the cover window of the glass material used in the existing flexible OLED has been changed to colorless PI material.

Colorless PI is thinner than conventional cover window glass, which is advantageous in reducing the radius of curvature and has the advantage of not breaking. UTG (ultra-thin glass), which has good surface touch-feel and scratch-resistant glass as thin as possible, is also attracting attention as a cover window material for foldable OLEDs.

At the SID Display Week exhibition in San Jose, KOLON exhibited colorless PI with hard coating. KOLON, which has been ready for mass production of colorless PI since 2018, is currently supplying colorless PI for foldable OLED cover windows to AUO, BOE, LG Display, and Royole.

Hard coating company DNP and TOYOCHEM also exhibited colorless PI with hard coating. DNP’s company official said that the film is under development and its main business area is hard coating, and TOYOCHEM’s company official said that it supplied hard coating samples to KOLON and SKC.

Meanwhile, SCHOTT, a UTG development company, also attracted the attention of the audience by displaying UTG for foldable OLED cover windows. An official of SCHOTT said that the UTG currently being developed is a cover window product for out-folding, not in-folding, and that the thickness is currently in development from 0.7 mm to 2.5 mm in accordance with customer requirements.

As the smartphone set makers are expected to release foldable OLED phones in the near future, competition for related materials is also expected to be intense. Whether the Colorless PI will continue to dominate or whether UTG will be able to exercise its influence is highlighted.

[28TH FINETECH JAPAN] Denso, Automotive displays that are directly connected to safety are OLED

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”.

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.

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

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.

[ICEL 2018] What are the future challenges for LG Display to improve OLED TV performance?

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.

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

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.”

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

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 smart phone, can it absorb tablet PC market?

“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.

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

“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.”

Following OLED, notch design to LCD becomes a marketing trend in 2018?

At the 6th China Information Technology Expo (CITE 2018) held in Shenzhen, Guangdong Province, China from April 8 to 11, 2018, a number of panel makers and set makers exhibited notch-designed display panels and smart phones.

In CITE 2018, five panel manufacturers exhibited in CITE 2018; BOE, EDO, GVO, Tianma and CSOT. Among them, BOE, Tianma and CSOT exhibited notch-designed display panels.

First, BOE introduced 6.2-inch OLED panels applied with notched design. The OLED panel exhibited by BOE has a resolution of 2992 x 1440 with 537 ppi and 400 nit brightness.

LCD panels also began to adopt Notch Design. Tianma presented a 6.18-inch LCD panel with a notch design. CSOT also exhibited two 6.25-inch LCD panels and a 6.18-inch LCD panel applied with notched design.

Since Apple first unveiled its OLED smart phone with the notch design on iPhone X, a number of smart phone makers such as Vivo, Oppo, and Huawei have begun to release OLED smart phones. In this exhibition, many panel makers presented a large number of LCD panels to which Notch Design is applied. Attention is growing whether Notch Design can become a trend in the small and medium sized display market in 2018.

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

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.

Vivo, which was the first to unveil the smart phone X21 with a built-in fingerprint sensor, displayed only the X21 model at its booth.  As a result of the actual registration testings, the fingerprint was recognized several times compared to the existing fingerprint registration, and the test recognition rate was not bad, but the response speed was slightly slower than opening the screen with the home button. In addition, most panel makers exhibited displays similar to the notch design of the iPhone X, which created various issues over the past six months, and set makers such as Vivo and Oppo released similar notch type smart phones. According to one official of some panel maker, the response to the design is not positive, but he said the company made it along with Apple. In his personal opinion, he preferred full screen design. Despite the sluggish performance of iPhone X, it still shows Apple’s strong market influence that the smart phones of the similar designs were released.

BOE, which started the operation of its Chengdu factory in 3Q 2017, exhibited various OLED panels made using plastic substrates. One official of BOE expressed confidence that it is only Samsung Display and BOE that can mass produce flexible OLED panels using plastic substrates across the globe.

LG Display, showing next generation OLED technology at ‘CITE 2018’

LG Display is showing OLEDs applied to various applications in the ‘China Information Technology Expo 2018’ held in Shenzhen, Guangdong, China from April 9 to 11, 2018.

CITE is the largest information/electronic exhibition in Asia hosted by China’s Ministry of Communications and the local government of Shenzhen, held every year recording more than 1,500 exhibitors participating and about 160,000 visitors attending.

Based on the slogan ‘OLED is already in the spotlight’, LG Display is demonstrating not only picture quality, but also the possibilities of OLED products in terms of application range and design.

OLED is widely regarded as the best display in the world in terms of brightness, color accuracy and viewing angle. In particular, large area OLED, has gained popularity in the premium market, which LG Display has developed uniquely and meets various consumer needs with different image quality and new design potential.

LG Display exhibited the world’s first 88-inch 8K OLED, which was unveiled earlier this year, attracting visitors. It is the largest of all existing OLED TV products and delivers four times (7680×4320 resolution) sharper picture quality than UHD (3840×2160 resolution). OLED is a self-luminous display, and is easy to realize high resolution 8K since there is no brightness drop due to the reduction of the aperture ratio. With LG Display’s innovative process/design and compensation technology added, OLEDs are expected to lead the ultra-large/ultra-high-definition market by realizing true 8K.

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

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

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.

OLED display to embroider the blue sky and stars inside the plane

“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

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.

Inkjet might take advantageous position for Gen11 super large OLED mass production line!

Toshiaki Arai, chief technologist of JOLED and James Lee, deputy chief engineer of TCL made presentations for the solution processed OLED on March 7 at the ‘4th OLED Korea conference’ held at Novotel Ambassador Hotel in Gangnam, Seoul, hosted by UBI Research.

Toshiaki Arai, chief technologist of JOLED announced that JOLED will focus on the medium-size OLED market for 10 ~ 30 inch tablets with solution processed OLED. He explained “OLEDs for mobile devices are currently targeting over 500 ppi and at least 800 ppi, which is hard for today’s printing technology. However, current printing technology is competitive enough since the medium-size OLED for tablets is 300 ppi level”.

He also added, “While it is required to divide the mother glass with the deposition technology currently in use, JOLED’s oxide TFT and solution process OLED can be adopted to Gen 8.5 as well as Gen 11 without cutting the mother glass. Thus, we expect panel production to be increased significantly.

James Lee, deputy chief engineer of TCL commented that the next-generation premium TVs are to implement 70-inch or larger screen, full black representation, high-definition at 8K resolution, and design differentiation such as slim & flexible. He said “solution process technology enables large RGB OLED implementation, which can improve image quality and reduce cost by using less material. TCL is currently developing solution process technology, which might be expected to be applied to its planned Gen 11 factory. ”

He commented “OLED TV prices are now approaching the price of LCD TVs based on 65-inch standards. In 2021, OLED TVs and LCD TVs will not differ in price, and OLED TVs will become the mainstream of the premium TV market. ”

2018 MWC- Release of LG Electronics’ V30S model, postponing announcement of new smart phone

LG Electronics released some of its stance, through 2018 MWC, on upgrading the entire mobile lineup, which led to lots of curiosities by the various related articles.

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

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.

At the 10th CAR-ELE JAPAN, Many Companies Unveiled Automotive OLED Display and Lighting

By Hana Oh (hanaoh@ubiresearch.com)

OLED display and lighting are expected to become increasingly applied to the interior and exterior of automobiles.

At CES 2018, Samsung Electronics introduced the OLED-applied dashboard. LG Electronics unveiled the center fascia with 14-inch OLED, and OLED set makers continue to exhibit their OLED applications for automobiles.

At the 10th CAR-ELE JAPAN held in TOKYO BIG SIGHT(Tokyo International Exhibition Center) on 17th, several companies including Tianma and Truly exhibited automotive OLED displays and lighting.

Tianma exhibited 4.2-inch, 5.46-inch and 5.99-inch OLED panels. The 5.99-inch OLED was a full-screen OLED, and the company official said “The full screen will be applied not only to mobile devices but also to automobiles such as CIDs and navigation systems due to the nature of automotive displays sensitive to visual impacts.” It is said they produced the OLED Panel with high luminance, including 5.46-inch and 4.2-inch OLED with luminance of 650 cd/m2, ensuring good high visibility under sunlight. In addition, they announced that they will manufacture unbreakable flexible type of OLED even though the exhibited OLEDs were all rigid type.

Meanwhile, in relation to OLED lighting, OLED light source companies such as LG Display and Osram supplied the OLED lights for tail lights to finished car makers such as Mercedes-Benz and BMW. In particular, it is expected to start the OLED lighting market in earnest, for example LG Display’s announcement of full-scale operation of the Gen5 OLED light source production line in December.

PMOLED and Micro OLED Stand Out In the Wearable Device Market

At the 4th wearable expo being held from January 17th in TOKYO BIG SIGHT -Tokyo International Exhibition Center, many companies attracted the attention of participants by exhibiting OLED wearable devices and OLED panels. Particularly, at this exhibition, many wearable devices with PMOLED and micro OLED were displayed, which proved once again infinite possibilities of OLED.

First, ColorLink Japan unveiled its VR and AR devices with micro OLED. Micro OLED is a panel that can realize high resolution in small size by reducing OLED panel to micro size. “The micro OLED applied to ColorLink Japan’s VR equipment is 0.7-inch in size with FHD resolution, and we were able to manufacture more compact and scarce VR device by applying micro OLED”, said an official from ColorLink Japan.

<ColorLink Japan’s Micro OLED VR and AR>

In addition, Fitbit and iWOWNfit exhibited smart bands with PMOLED. PMOLED refers to a passive matrix OLED that does not use TFT, which is a switching device, and is mainly applied to low resolution devices that display numbers or characters rather than high resolution-required devices. In relation to the reason for the application of PMOLED, both companies explained that they have been able to significantly reduce power consumption by applying PMOLED, and the OLED prices have fallen considerably so that they have sufficient price competitiveness.

Meanwhile, OLED panel makers also exhibited a number of OLED panels for wearable devices. Pioneer, which firstly produced mono color PMOLED for FM character broadcast in 1997, attracted participants by introducing a number of PMOLEDs and devices using this. Pioneer announced its goal to diversify its business centering on PMOLED, introducing PMOLED-applied Bluetooth speakers, smart watches, and AR devices.

<OLED light field display description and specification>

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

<Principle of plane source deposition technology developed by OLEDON>

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

[iMiD 2017] You Dream, We OLED

LG Display is expanding in earnest in OLED market.

In the keynote session of IMID 2017 held in Busan on 29th, LG Display’s CTO Kang In-byeong pointed out the future plan of LG Display as “OLED is a strong candidate to lead the future display industry”.

Kang In-byeong, CTO, said that by 2020, large-area OLED will increase its production capacity by 7 times to 2020, thereby reducing the cost cap with LCD and leading the market on the basis of technology such as wall paper, sound integration, rollable and transparent flexible. LG Display recently invested in Gen8.5 in China and is expected to invest in Gen10.5 OLED mass production line at Paju P10 plant.

On the other hand, for small and medium-sized OLEDs, they have announced that they will use a fast follower strategy based on plastic OLED. LG Display is in mass production of plastic OLED panel to be applied for LG Display’s next smartphone, V30, next smartphone, and is ready for the mass production in the E5 line of Gumi. In addition, they plan to invest 10trn won additionally to Gen6 line, which is expected to increase 13 times the current capacity by 2020.

Based on this aggressive OLED investment, LG Display plans to raise its portion of OLED sales up to 40% in 2020 from current 5% in large-area OLEDs and small- and medium-sized OLEDs.

Currently, large-area OLEDs continue to increase capacity and yield and LG Display is likely to expand sales in the future, as it is dominating the premium TV market as it is expanding the camps of Sony, Philips and Panasonic as well as LG Electronics. The success of mass production in small- and mid-sized OLEDs will determine whether or not LG Display plans to achieve its plan.

LG Electronics is expanding its OLED TV camp to dominate the premium market. LG Electronics decided to supply OLED TV since September to Danish prestigious audio company B & O (Bang & Olufsen), making a fruitful result of OLED TV expansion.

‘B & O’ held an OLED TV public event in Berlin on Aug 30th in local time. ‘LG OLED TV is equipped with its own sound technology and will be shown to visitors at ‘IFA 2017’ from September 1 to 6.

LG Electronics also emphasized that the OLED TV camp is on the constant rise. It is expected that there will be 13 manufacturers exhibiting OLED TV at ‘IFA 2017’. As the number of companies increased from 11 last year, it is said that these companies are planning to execute their premium marketing strategies by bringing OLED TV in front.

LG Electronics analyzed that mushrooming OLED TV sales among many companies are attributed to securing a stable profit structure. As Chinese and Taiwanese makers are investing heavily in LCD panel production, the price competition is likely to be intensified in the future and LCD technology has already reached the maturity phase, difficult to be differentiated with LCD. Taken the market environment into consideration, TV makers have been targeting a premium market with differentiated OLED TV.

LG Electronics announced that OLED TV makes the profit structure of LG Electronics stable and secure. The HE division in charge of TV business stated that it achieved 8.5% of operating profit (sales 8,561 billion KRW, operating profit 725.2 billion KRW) in the first half of this year. LG Electronics mentioned the premium OLED TV has brought the high profitability and noted that OLED TV sales accounted for 15% of sales in the first half of LG Electronics’ business operation.

The LG OLED TV currently being commercialized has swept the various awards by media and experts all over the world, and is ranking number one in the performance evaluation. The screen quality, sound quality and design have been complimented in the TV’s key elements.

Particularly, at ‘IFA 2017 in Berlin Germany, LG Electronics will aggressively approach and further strengthen the premium TV market from September 1 to 6, introducing the advanced screen quality technology of ‘LG OLED TV’. “We will enhance our leadership in the global market by bringing OLED TV presently reorganizing the premium market in front.”
