OLED Encapsulation Transparent Gas Barrier Film Market, How High Can It Grow?

/0 Comments/in /by

At present for flexible AMOLED encapsulation, thin film encapsulation, where organic and inorganic thin films are laminated, and hybrid encapsulation, where minimum passivation and gas barrier film are laminated, are used in mass production. As large area AMOLED panel is being mass produced through bottom emission structure where the light is emitted toward substrate, metal foil utilizing hybrid encapsulation is used.

 

However, TFE method which is used in flexible AMOLED panel for mobile device employs expensive manufacturing equipment and increases the investment cost. It also increases the number of processes involved and reduces mass production efficiency. For these reasons, this method is not suitable for cost reduction. As large area requires high resolution and high brightness, top emission structured AMOLED panel is being developed. When top emission structure is used, transparent encapsulation is essential.

 

Following this trend, the necessity for next encapsulation is rising, and in particular, transparent gas barrier film encapsulation is receiving increasing amount of attention. The transparent gas barrier film that is used for the hybrid structure currently being applied in mass production has WVTR of 10-4g/m2day, which is less than encapsulation requirement of 10-6g/m2day. However, in R&D stage, the WVTR level reached to 10-6g/m2day, and encapsulation could be possible only with transparent gas barrier film. Research development regarding this is being actively carried out.

 

According to 2016 OLED Encapsulation Report, published by UBI Research, transparent gas barrier film encapsulation can reduce investment cost compared to TFE. As it can also be applied to large area top emission structure, high market growth can be anticipated with this encapsulation.

 

UBI Research analyzed that if transparent gas barrier film encapsulation is applied to the new large area line and mobile added from 2017, the transparent gas barrier film market could grow to record up to approximately US$ 700 million in 2020.

Will 2016 be the Year of Glasses-Free 3D Display Commercialization?

/0 Comments/in /by

During the Pioneer Technology Seminar to Overcome Display Industry Crisis (January 14) held in South Korea, Dr. Sung-Kyu Kim of Korea Institute of Science and Technology (KIST) discussed the current issues of glasses-free 3D display and technology development for commercialization. He also revealed related KIST research results.

 

At present, the 3D display applied to TV can be divided into FPR (film patterned retarder) method and SG (shutter glass) method. Both of these methods require 3D glasses. Regarding this, Kim revealed that the glasses using method could be the biggest factor in hindering the 3D display’s accessibility. Kim announced that glasses-free 3D display development is essential particularly for outdoor advertisement applications.

 

To increase the accessibility of 3D display, glasses-free 3D display related research, such as holographic and multiview 3D display technology, has long been carried out. Kim revealed that at present the multiview 3D technology is closest to glasses-free 3D display commercialization. He added that the key issue is how much the 4 problems (crosstalk development, quantization effects between viewpoints, reduced resolution, human factor) can be controlled.

 

In order to solve these problems, Kim applied technology that forms visual field of 4 or more views between eyes and provide same image information in the adjacent area. He emphasized that this was fused with technology that tracks the location of the observer and developed improved glasses-free 3D display. He added that prototype was shown in PyeongChang 2018 Olympics PR venue and Sangwolgok Station in South Korea.

 

Kim explained problems such as human factor occur for TV and monitor where observers watch for a long period of time and future of 3D display is not bright. However, in advertisement area where people can freely watch, it could be effectively applied. He revealed that he will focus on commercialization this year and expedite development.

Quantum Dot, Will it Rise to Become the Answer for Future Display Materials?

/0 Comments/in /by

The interest in quantum dot materials is increasing daily. In July 2015, Professor Changhee Lee of Seoul National University received Science Technology Person of the Month prize with technology that greatly improves QLED performance and lifetime. In CES 2016, with cadmium-less quantum dot applied SUHD TV, Samsung Electronics achieved UHD TV’s color standard BT.2020 and received much attention.

 

Regarding this interest, during the Pioneer Technology Seminar to Overcome Display Industry Crisis (January 14) held in South Korea, University of Seoul’s Professor Jeong Hoon Kwak reported that quantum dot technology is a material with plenty of potential from the long-term perspective.

 

Quantum dot materials can be used with blue LED to improve LCD color gamut. Two techniques are generally used; the edge type has quantum dot placed on the sides and for surface type the quantum dot film is attached in front of BLU. Most of TV makers, excluding Sony, are using surface type. Professor Kwak explained that quantum dot can achieve desired color by adjusting the size of the particles without changing the materials. Through this, he estimated that it could replace color filter.

 

As well as increasing the LCD color gamut, as quantum dot materials emit light when connected to electricity, much like organic light emitting materials, it is anticipated that they could be used to replace the emitting materials in OLED panel. Within the industry, this technology is called QLED or QD-LED (Quantum Dot Light Emitting Diode) technology. Professor Kwak emphasized that QLED has better color gamut than OLED and has a merit of good actualization of deep blue. As QLED is basically formed through solution process, he added that solution process pixel patterning technology has to be development and device lifetime also has to increase.

 

Professor Kwak explained that as there are not many places mass producing QLED materials at present, the cost is high. However, he emphasized that because the quantum dot materials have an advantage of being easy to synthesize, from long term perspective, they can be used at lower price than OLED.

 

[Lighting Japan 2016] What is the Key Issue of Solution OLED Materials?

/0 Comments/in /by

In Lighting Japan 2016 (January 13-16) conference, Sumitomo Chemical and Merck revealed recently developed soluble OLED materials performance results.

 

The soluble OLED materials efficiency published in this conference reached ≥ 65% of UDC’s evaporation materials; particularly, Sumitomo Chemical’s red achieved ≥ 85%, and green reached ≥ 88% of UDC’s evaporation materials efficiency. Lifetime (LT 95) results were not as good as efficiency with red’s 25% and green’s approximately 40% (average).

 

Sumitomo Chemical and Merck both revealed that although in terms of efficiency the soluble materials almost caught up to evaporation materials, but lifetime requires further development.

 

Solution process is a method that allows for large area OLED panel production in RGB method using ≥ Gen8 manufacturing equipment. Key panel companies are actively carrying out research development, and the performance of soluble OLED material is considered the biggest issue. According to Solution Process OLED Report 2015, published by UBI Research, when solution process is applied the material cost can be approximately 40% reduced compared to the current evaporation process using large area OLED panel. The timing for the solution process application to mass production is expected to be decided depending on the development speed of soluble OLED materials.

Osram Bussiness Unit Digital Systems’s CEO, Geert van der Meer, Lighting Japan 2016

 

In Lighting Japan 2016 Keynote Session, Geer van der Meer, CEO of Osram Business Unit Digital Systems, suggested directions for future lighting industry.

 

Geert van der Meer explained that the current lighting market is rapidly adopting LED, but the large volume of Chinese products is decreasing the price of LED source and device quickly. He emphasized that with the trend of disappearance of lighting companies’ profit, new business format is required to create profit.

 

The new businesses suggested by Osram are embedded lighting, and connected and smart lighting. He suggested lighting industry should move toward where the lighting can be used as part of building materials through internal installations and utilization as indirect illumination, and adopt smart system and form smart building and furthermore, smart city.

 

The current lighting market’s players are being joined by IT related companies, BMS (business management system) companies, and electronic appliances companies, and its megatrend is changing rapidly. Accordingly, Osram is expanding from the existing lighting to lighting electronics such as module and control gears, lighting solution system, and specialty lighting such as OLED and automotive. Osram also revealed that they took over a wireless energy management system company called ENCELIUM and intensifying focus on smart lighting system business.

 

Smart system provides many different functions such as energy reporting, remote and preventative maintenance, personal lighting control, and zone analysis among others and can optimize energy reduction, maintenance cost reduction, and workspace environment. Van der Meer emphasized that new function can be created through lighting used area’s data analysis and become the focus of future lighting analysis.

[Analyst Column] CES 2016 Press Conference Comparison Analysis, Samsung Elec. TV vs. LG Elec. TV

/0 Comments/in , , , , , /by

Choong Hoon Yi, Chief Analyst, UBI Research

 

When Samsung Electronics, CES’ most important company, holds a press conference, members of the media wait longer than an hour anticipating the new world the firm will show. For LG Electronics’ press conference, the waiting period is relatively shorter.

 

However, the press conferences at CES 2016 were not as anticipated. In CES and IFA, the representative of electronic appliances companies is TV. However, the TV in Samsung Electronics’ event was merely the same SUHD TV as shown before. Instead, ICT area, such as VR, USB adaptor, and Samsung Pay, was emphasized. During the last year’s CES, Samsung Electronics received much acclaim with curved design added SUHD TV. The only difference for this year’s TV from CES 2015’s was the text ‘Quantum Dot Display’ underneath the SUHD.

 

 

Samsung Electronics is considered the rule maker of the market with new designs and aggressive marketing. The fact that Samsung Electronics only added the words quantum dot to the already applied SUHD TV LCD panel is analyzed to be a desperate measure demonstrating the LCD TV’s development limitation.

 

On the other hand, during their press conference, LG Electronics provided a vision where the TV market can have another growth spurt through the introduction of the improved OLED TV with 800 nit peak brightness. Particularly, NASA’s video of vivid deep black of the space and dynamic fiery red of the sun on the OLED TV brought the audiences to cheer and applause. What could only have been seen by astronauts can now be seen by everyone through OLED TV. This was an event where everyone could feel what a true display really is.

 

 

Of course, as the largest market of the consumer market is smartphone, it would be illogical to discuss Samsung Electronics and LG Electronics with only TV. However, Samsung Electronics’ smartphone business also remained stationery last year and all businesses, excluding semiconductor, is falling downward. As such, for Samsung fans who have high expectations it is of much concern.

 

The reason that the companies that led electronic appliance industry for the past half century such as Sony, Panasonic, and Toshiba are falling is because they did not have paradigm changing technology and product when the market was stalling. The same unfortunate sign is coming from Samsung Electronics.

 

Chinese set companies including TCL also brought quantum dot technology applied LCD TV to CES 2016. 8K TV was also exhibited. Although the picture quality control technology of the Chinese TV companies still falls short compared to companies such as Samsung Electronics, LC Electronics, and Sony, the set exterior reached similar standards and the price is less than 70% of the early starters’. The difference in the picture quality is difficult to distinguish for those who are not TV or display experts. The quality of Chinese products does not reflect the cheaper price, and cheap and good products are pouring in from China.

 

For Samsung Electronics that cannot produce OLED TV, in order to repeat the last year’s popularity in international events such as IFA in later this year, a big issue and product that can represent the company are urgently needed.

The panel used is 5.7 inch 518 ppi FHD OLED.

 

According to Huawei, although until now LCD has been used as OLED can produce profound black it is estimated OLED will be highly popular in Chinese market.

 

Huawei is already using OLED on smartwatch. Huawei Watch Active that began to be exhibited starting with CES 2015 uses 1.4 inch 286 ppi OLED panel with 400 x 400 resolution supplied by AUO. The thickness of the watch is 4.2 mm and rather thick, but the external design is highly detailed and beautiful much like luxury analog watch.

As Huawei, which has the highest market share out of Chinese set companies, started to actively push for OLED panel use in smartphone following smartwatch, other Chinese companies, including Xiaomi, are expected to rapidly join the OLED sector.

[CES 2016] Skyworth’s 2016 OLED TV Sales Target is 200,000 Units

/0 Comments/in /by

Skyworth, the most enthusiastic Chinses TV company, placed OLED TV on the front of the CES 2016 booth, the largest space.

 

 

The exhibition concept, same as IFA 2015, was promotion of OLED TV’s superiority over LCD in terms of picture quality and fast response time through car racing game.

 

Furthermore, all OLED TVs exhibited this year are UHD resolution aiming for the premium TV market.

 

According to Skyworth, 2015 OLED TV sales performance is 45,000 units, with the target of 200,000 units in 2016. In 2015, the performance was weak as the OLED panel supply from LG Display was not smooth. However, compared to last year, in 2016 the panel supply from LG Display increased, and as OLED TV is a very popular product in Chinese market due to its superior picture quality compared to LCD the sales target of 2016 became much higher.

 

What is different about this exhibition is the fact that the video clip used in the Skyworth OLED TV booth is the same as the NASA video produced by LG Electronics for promotion. Previously, each companies presenting OLED TV used different contents on the screen. However, in this exhibition, by showing the same video of the sun within the space, they emphasized OLED TV’s superiority in contrast ratio and picture quality of black.

 

 

This is considered LG’s ecosystem strategy to secure OLED TV territory by sharing the video contents and increasing the consumers and attendees’ OLED TV awareness.

The exhibition showed rapid development of LG Display’s OLED technology.

OLED Takes Over Monitor and Notebook Markets Too

/0 Comments/in /by

Following the mobile and large area panel markets, OLED is now actively entering the monitor market.

 

Until now, the monitor and notebook markets were mostly occupied by LCD. Burn-in effects and power consumption were the biggest reasons that prevented OLED panels from being applied to monitor and notebook. Generally, monitor and notebook are for office use. Within the office environment, window’s task bars and icons on the main screen are fixed. Also, as the average hours of use is much higher than TV or mobile, burn-in effects is an issue. Also as Office programs or internet browsers, which usually have white background, are used heavily, power consumption is high as OLED panel of RGB method has to drive all subpixels in order to actualize white.

 

Starting with the black and white OLED monitor in 2012, Sony steadily developed/mass produced OLED monitor. However, it is analyzed the application was possible as this OLED monitor was mostly used for medical and broadcasting uses and in different settings from the office monitor environment.

 

However, with Lenovo and HP’s announcements of OLED Notebook release, the status is changing.

 

In January 2016, Lenovo announced world’s first OLED notebook ‘X1 Yoga’ with 14 inch AMOLED panel with 2550×1440 resolution. Following this, HP also announced the release of 13.3 inch OLED hybrid laptop/tablet ‘Specter X360’ with 2560×1600 resolution.

 

These OLED panel equipped notebook releases break the existing perception that OLED panel is not suitable for monitor and notebook, and can be considered that OLED panel’s lifetime and power consumption have been achieved to be suitable for monitor and notebook. As such, much attention is on whether the OLED market will be able to greatly expand in the monitor and notebook markets following their success in mobile and TV markets.

[CES 2016] OLED TV Passes UHD Alliance Standards

/0 Comments/in /by

ces1

 

As a press event of CES 2016 (January 6-9), UHD Alliance, which was created by TV manufacturing companies, contents companies such as film studios, and picture and sound quality related companies to energize the declining TV market, gave a presentation on future UHD TV market and UHD Alliance activities.

 

The TV market recorded approximately 230 million units in 2015. However, this is 20 million units fewer than 2014’s 250 million, and CES reported that 2016 performance will be similar to 2015. 2016’s estimated UHD TV market, which is the premium market of 55 inch or larger, is 21% of the total TV market with approximately 48 million units.

 

The 4 key factors that UHD Alliance is pursuing in UHD TV are image resolution, color bit depth, color palate, and high dynamic range.

 

LCD TV and OLED TV that satisfy these factors are to be available from this year. In order to respond to OLED’s vivid color realization, LCD TV companies developed quantum technology. Also to draw near OLED’s contrast ratio of 1,000,000:1 they are continuing technology development, but the LCD contrast ratio remains around 3,000:1.

 

It is worth noting that UHD Alliance provided 2 HDR specs: more than 1,000 nits peak brightness at less than 0.05 nits black level, or 540 nits brightness with 0.0005 black level.

 

LG Electronics already achieved UHD Alliance’s HDR spec of 540 nit peak brightness last year, and this is analyzed to provide foundation for more invigorated future OLED TV market. Based on this, OLED TV is expected to be the main force within the UHD TV market.

 

Additionally, UBI Research estimated that 2016 OLED TV market will record 1,200,000 units.

Can Transparent OLED Be OLED Industry’s New Growth Engine?

/0 Comments/in /by

According to Transparent OLED Display Report 2016, published by UBI Research, large area transparent AMOLED market is expected to record approximately US$ 5,300 million by 2020.

 

UBI Research revealed that “transparent OLED, with its high transmittance, is likely to be applied to transparent advertisement display such as showcases that has to properly actualize what is behind the display. Also, as the viewing angle is wide and color gamut and visibility are high, it will be widely used as transportation display such as automotive”. Furthermore, UBI Research added that as it is easy to produce flexible product and can be utilized in diverse applications that will be newly designed, market potential is very high.

 

Transparent display is a display that can recognize/process/communicate information via optically transparent display using transparent electronic device. This is a device that is ordinarily transparent as glass and functions as monitor or TV as needed. As the area where the information is shown is transparent and objects behind the display can be seen, spatial/visual limitation can be overcome and diverse application and expansion of existing display market can be anticipated. Particularly, transparent OLED’s transmittance is approximately twice as high as transparent LCD (using the recently release panel), and simple to bend. As such, key panel companies are inclined to actively develop transparent OLED.

 

In 2015, Samsung Display revealed world’s first 55 inch FHD transparent OLED with 45% transmittance and plan to mass produce from 2016. LG Display is also developing transparent OLED through project titled “60 inch or larger UD level transparent flexible display with transmittance of 40% or higher” that began in 2012. China’s BOE presented 9.55 inch transparent flexible OLED panel with 30% transmittance in SID 2015 and is actively carrying out research.

 

From these companies’ transparent OLED development, transparent OLED is anticipated to play a big role in future display market expansion.

Looking Ahead to 2016 OLED Industry through Keywords

/0 Comments/in /by
  1. Flexible AMOLED Investment

In 2016, flexible AMOLED mass production line investment is expected to be actively carried out by Samsung Display, LG Display, BOE, and Japan Display. For Samsung Display to apply flexible AMOLED panel to the new Galaxy model, the mass production line investment is necessary. If they supply flexible AMOLED panel to Apple, volume of the flexible AMOLED mass production to be invested in 2016 is estimated to be grow significantly. LG Display also is expected to actively carry out flexible AMOLED line manufacturing equipment order for Gumi’s P6 line, as well as additional flexible AMOLED mass production line investment following Apple’s demand. BOE is estimated to seriously begin orders for Chengdu’s Gen6 45K flexible AMOLED mass production line.

 

  1. P10

With the announcement of new factory establishment and 1.84 billion KRW investment for part of facilities in Q4 2015, as the first step of the investment, LG Display began site construction for P10 line factory that can produce large area panel. However, the investment direction has not yet been decided. P10 could be directed to only producing large area LCD panel, large area OLED panel, small-to-medium size OLED panel, or large area and small-to-medium size OLED panel simultaneously. China’s Gen8 LCD facilities investment is quite advanced and BOE’s Gen10.5 LCD line investment has also been confirmed. As such how much LG Display’s large area LCD can bring profit has to be carefully considered. Additionally, with the increase of OLED TV consumption and the supply of OLED panel to Apple practically confirmed, OLED investment is essential. P10, Gen11 line, is the world’s largest factory site, and depending on the investment direction in 2016, it is estimated to affect OLED market’s opening time.

 

  1. Chinese OLED

Everdisplay is supplying AMOLED panel to some several Chinese set companies, and Visionox is also expected to actively supply AMOLED panel from 2016. As such, most of Chinese OLED panel companies’ OLED mass production preparation is anticipated to conclude in 2016. Accordingly, second investment by companies including Everdisplay, Visionox, and Tianma is analyzed to be possible and serious movement by China’s OLED industry could occur.

 

  1. Evaporation Equipment

Flexible AMOLED mass production line investment by Samsung Display, LG Display, Japan Display, and BOE, and other Chinese OLED panel companies’ additional installation are expected to be actively carried out from 2016. Amidst this, order of evaporation equipment, OLED production’s essential component, is expected to be an issue.

 

Evaporation equipment currently being used in mass production is mostly Japanese Canon Tokki’s. As this evaporation equipment has been verified in mass production, it is estimated that most companies, including Samsung Display, LG Display, BOE, and JDI, will want to order Canon Tokki’s evaporation equipment. However, as the production capa. of Canon Tokki’s evaporation equipment is limited, the issue is expected to be which panel company will be able to order early. At the same time, this could be a new opportunity for Korean evaporation equipment companies.

 

  1. Samsung OLED TV

At present, the TV industry trend is moving to OLED from LCD. Accordingly, Samsung Display is continuing research to resume their large area OLED for TV panel business. It is analyzed that Samsung Display possesses RGB OLED technology that uses SMS evaporation method, white OLED, and solution process OLED technology. However, as each technology has its drawbacks, they are carefully considering future directions. First, RGB OLED technology is estimated to lack Gen8 mother glass substrate evaporation equipment at present. Solution process OLED method has low material performance. For white OLED, as the key patents are owned by LG Display, technology that avoids these has to be first developed. Therefore, much attention is focused on which technology Samsung Display will use and invest in production line to enter the TV market.
