今回の展示を通じて、BOEとCSOTがそれぞれ55inch UHD OLEDと31inch curved OLEDで中国メーカー初のタイトルを持つようになり、今後、WRGB OLED panel市場の成長に新たな原動力になれると期待される。

BOEは、HefeiのGen8パイロットラインで、CSOTは中国ShenzhenのGen4.5 R&Dラインで、OLED TV用のpanelを製造しており、両社は、大面積OLED量産ラインへの投資を積極的に検討している。

現在、大面積OLED panel市場は、LG Displayが唯一に量産ラインを保有しており、単独でOLED panel市場を導いている。今後、BOEとCSOTが大面積OLED panel市場に加勢すると予想され、大面積OLED panel市場での競争を通じた市場の拡大が行われると期待される。

Chinese media reported that CSOT (China Star Optoelectronics Technology) is planning to invest $ 7,740 million in constructing Gen11 TFT-LCD panel mass production line.

According to the Chinese media, this company is planning to establish the Gen11 LCD mass production line in factory located in Shenzhen, south of China. The line is for 45 inch and 66 inch large area panel for TV. This mass production that CSOT is newly building is known to produce 3000mm x 3000mm or larger using glass substrate, and cut in 18 different sizes with the highest cutting efficiency of 97%.

Of Chinese panel production companies, CSOT has the second highest market share after BOE. At present, CSOT is operating Gen8.5 mass production line for large area panel and Gen6 LTPS line for small to medium-sized panel in Wuhan area in China. It also intends to establish another small to medium sized OLED panel mass production line for smartphone and tablet in Wuhan this year.

Higher the Generation of the line, it is more advantageous for large area panel production. If BOE completes Gen10.5 line construction, and CSOT Gen11 line, this means China is equipped with superior price competitiveness within large area LCD panel sector such as 60 inch panel for TV. Accordingly, the trend of LCD panel market leadership transference from Korea to China looks to be accelerated.

In fact, Korean key display companies, including Samsung Display and LG Display, only possess, at maximum Gen8 mass production line manufacturing equipment. Many display experts estimate that due to the supply of LCD pouring out from China, Korean display companies will record deficit in Q1 2016.

Foxconn is expected to occupy approximately 22% of 2016 Q4 global large size panel yield, similar to the levels of Samsung Display and LG Display.

Foxconn, recently confirmed to buy 66% of Sharp’s stake for $ 3.5 billion, is estimated to actively invest in improving Sharp’s panel competitiveness against Samsung Display and LG Display.

DigiTimes recently reported their research indicates Sharp’s large size panel yield will occupy 5.3% of global market in Q4 2016. This places the company on the 7th place after Samsung Display, LG Display, Innolux, AUO, BOE, and CSOT.

However, Sharp and Innolux are under Hon Hai Precision (Foxconn Technology). If the Q4 2016 large size panel yield of Sharp and Innolux are combined, the global occupancy is added to 21.9%. This is approximately the same level as Samsung Display (23.7%) and LG Display (22.7%).

Foxconn is analyzed to be investing in Sharp mainly with focus on OLED. According to a recent DigiTimes article, Foxconn is planning to invest approximately US$ 1.8 billion in OLED development.

DigiTimes estimates that Foxconn will actively begin mass production of OLED for smartphone from 2018, and expand the production to large and medium-sized OLED panel for TV, notebook, etc. Foxconn is forecast to begin shipment of OLED for TV from 2021, and annually ship 7,200,000 units of OLED panel for TV in 2025.

Korea, China, and Japan’s OLED TV Alliance to Boost the Market

Korean companies had been leading the OLED TV industry. Before SID 2015 (31 May – 5 June), LG Display and Samsung Display had been the only companies to reveal 4K OLED panels, and until now, LG Electronics has been the only company to sell 4K OLED TV in large quantity. In terms of OLED TV market, despite OLED’s superior characteristics compared to LCD regarding contrast ratio, high viewing angle, fast response time, and thinness, the market share has been limited mostly due to its relative high price. However, this is expected to change soon.

 

LG Electronics has been pushing for OLED TV alliance and corporation with Chinese and Japanese companies. As a result, Chinese and Japanese companies resolved to jump into OLED TV market from the second half of 2015. Japan’s Panasonic and Sony are expected to release OLED TV for the first time later this year. China’s Skyworth, Changhong, Konka, and Hisense are expected begin sales from this fall.

 

Consequently, the number of set companies producing 4K OLED TVs will increase to 7 by the end of 2015. LG Display, the only company that can mass produce OLED panel with 4K resolution, is planning to increase production by 4 times this summer to supply these new to OLED TV set companies.

 

As mentioned above, until SID 2015, LG Display and Samsung Display had been the only companies which showed 4K OLED panels, and with LG Display being the sole company able to mass produce 4K OLED panels. However, in SID 2015, AUO showed their own 4K OLED panel during an author interview session, and CSOT and BOE presented paper on 4K resolution OLED panel. This signifies they possess technology needed for OLED panel production, and with proper investment they can begin mass production.

 

Soon LG Display will no longer be the lone supplier of OLED panels contributing toward increase in shipment of OLED panels and OLED TVs. This will naturally lead to lower cost for consumers and energize OLED TV market.

[SID 2015] Chinese LCD’s Continuous Evolution. OLED, What To Do?

LCD technology of Chinese companies is continually evolving. In SID 2015, BOE exhibited world’s largest 110inch 8K and world’s first 82inch 10K LCD panels. CSOT drew much attention with its world’s largest 110inch UHD curved LCD TV. By exhibiting ultra high resolution and large size LCD panel ahead of Korean and Japanese panel companies, CSOT aptly demonstrated that Chinese companies have caught up to Korean and Japanese technology skills.

BOE presented NTSC 99% 27inch QHD LCD panel, and CSOT showed NTSC 118% 55inch UHD LCD panel. Particularly, CSOT exhibited 4mm thick 32inch FHD LCD TV and 5.5 mm thick 4K curved LCD panel; this showed that LCD is able to catch up to OLED’s thinness and color gamut advantages. Thus, with LCD’s continuous new technology development and price competitiveness, LCD and OLED’s leadership competition will once again heat up in next generation display’

The current large area TV market is led by LCD and OLED is slowly expanding the market starting with premium TV. Even in premium market, with price competitiveness LCD is one step ahead with QD film applied LCD TV. Therefore, the technology development of LCD that is catching up to OLED’s advantages is expected to be a hurdle for OLED’s market opening.

Although LCD’s color gamut, thickness, contrast ratio, and response time is being continually improved and can approach to OLED’s level but cannot be equal to OLED in all areas. For example, if the thickness is reduced in LCD, the QD film application needed for increased color gamut is difficult. Even if panel with many positive traits altogether is developed, it is expected to take much time giving OLED chance to drop the price to LCD level. Therefore, reducing OLED panel’s price by OLED’s active investment and yield achievement is analyzed to be an essential condition for next generation display leadership.SID 2015 중국업체의 끝없는 개발 SID 2015 중국업체의 끝없는 개발2
