/0 Comments/in /by

A surge of AMOLED panels by Chinese set companies is starting. Chinese set companies exhibited many AMOLED panel applied products in MWC 2016 (Feb 22 – 25), forecasting that the demand for AMOLED panel could greatly increase.

 

6 companies, including Huawei, ZTE, LENOVO, and Gionee, exhibited AMOLED panel applied smartphones. Particularly, Hisense and KONKA, well known as TV set companies, presented AMOLED panel smartphones and the Chinese set companies’ increased interest in AMOLED panel could be confirmed.

 

The majority of the AMOLED panel smartphones exhibited by Chinese set companies had 5 inch level panel with HD and FHD level resolution, and analyzed to have been supplied by Samsung Display.

 

Samsung Display is known to have significant amount of mainstream AMOLED panels to Chinese set companies in 2015. Following this trend, over 100 million units of AMOLED panels are expected to head toward China in 2016.

 

The key points are Samsung Display’s rigid AMOLED panel production capa. and whether the Chinese AMOLED panel companies can carry out mass production. The current Samsung Display’s rigid AMOLED panel mass production capa. is estimated to be insufficient to meet the demands for Samsung Electronics’ mainstream Galaxy model and Chinese set companies. Chinese panel companies have also announced active mass production from the first half of this year.

 

From the significant occupation of Chinese set companies that applied AMOLED panel within the Chinese smartphone market, panel companies’ supply ability of AMOLED panel for Chinese set companies is expected to be one of the issues in 2016.

OLED Frontier Forum’s 3rd Section Panel Discussion Summary

/0 Comments/in /by

The 3rd section of the 1st OLED Frontier Forum (Jan 28), OLED’s Future, held a panel discussion with government, industry, and academia experts discussing OLED industry development strategy, such as next generation technology development, convergent areas, and personnel training, and future forecast. OLEDNET summarized the answers that each expert gave to the questions of the panel chair (Professor Changhee Lee, Seoul National University).

 

Jun-hyung Souk (Professor, Sungkyunkwan University)

For SDC mobile, as the OLED depreciation is ending the OLED production cost is becoming almost the same as LCD. If OLED related experts stay within Korean industry as well as the technology, Korea can continue to lead for 4-5 years. In order to achieve the continued leadership, differentiation through flexible R2R has to be carried out, as well as the materials and encapsulation technology development.

 

 

Sung-Chul Kim (CTO, SDC)

As a-Si is an existing technology, there is no room for further advancement. Sharp’s difficulty in panel business is due to lack of technology research on the panel. Because one technology can only be used for approximately 7 months, diverse technology development is required.

 

 

In-byeong Kang (CTO, LGD)

Fast organizations cannot but win. Therefore, rapid change to OLED from LCD is needed. As difficult is the technology, cooperation between academia and industry is needed. Now is the time when this cooperation for next generation technology development is more in demand. LGD is putting in much effort for OLED profitability.

 

 

Sung-Jin Kim (Vice President, Toray Advanced Materials Korea)

Cooperation between materials and manufacturing equipment companies is important in solution process materials development. Particularly, how to control dry process is an important issue. Also, Kim expects the current solution process materials development to show tangible results in 3-5 years.

 

 

Junyeob Lee (Professor, Sungkyunkwan University)

Solution process is favorable for materials optimization. From the initial concentration on polymer materials, recently small molecule materials focused soluble materials development is being carried out, and how to implement common layer is an issue. Emitting layer is using the small molecule materials that are being used as evaporation materials. The difference is the higher cost as the solvent is used. Also, as there is an issue (formulation problem) when used in large area, solution is required.

 

 

Kyoung-Soo Kim (Vice President, Korea Display Industry Association)

Expert acquirement is a key issue. Through upgraded cooperation between industry and academia, and industries, cooperation between panel, manufacturing equipment, and materials has to progress into a positive cycle. Also the open platform regarding new OLED application is needed.

 

 

Young-Ho Park (PD, Korea Evaluation Institute of Industrial Technology)

Flexible display competitiveness acquirement is a big concern. Programs for challenging R&D, and high added value product/technology development, and R&D infra establishment (highly cost-effective R&D) have to be considered.

Sung-Chul Kim, Samsung Display’s CTO, at the 1st OLED Frontier Forum (Jan 28) gave a presentation ‘AMOLED Technical Issue and Future’ and discussed OLED technological issues of the past and present.

 

Kim pointed out the fact that glass substrate is not always necessary for OLED as the most different factor compared to LCD, and emphasized flexible OLED where plastic substrate is used. Kim reported that flexible OLED issues include window’s durability and coating, touch panel’s electrode materials and flexibility, reduction of number of encapsulation layers and flexibility, and backplane’s low stress structure and OTFT application. He revealed that developing spherical stretchable display, which the user can zoom in, is also included in the product roadmap.

 

Regarding transparent/mirror display, Kim announced that this is the direction that OLED should head toward and added that layout design development suitable for different application areas is needed. Specifically, the transparent display should be developed to increase the transmittance area and decrease the TFT area, and the mirror display to optimize the ratio between the total reflection and half-reflection areas.

 

Additionally, in order to produce high resolution OLED, Kim mentioned that innovation in terms of pixel operation and backplane structure is needed. He emphasized compensation circuit and that whether high resolution display can be manufactured cheaply and using simple structure is the key.

 

Kim discussed wall display, IoT, educational display, etc. as the new applications which will become important in future. Particularly, mentioning the automotive display area, Kim explained that for OLED to enter these new areas, plastic materials suitable for each applications and technology that can correctly process this are required. In order for this type of research development to be carried out smoothly, Kim added that cooperation between the academia and industry is necessary.

 

In-byeong Kang, CTO of LG Display, Discusses the Past, Present, and Future of Large Area OLED Panel

/0 Comments/in /by

On January 28, Korea Display Industry Association organized the 1st OLED Frontier Forum in JW Marriott Hotel Seoul.

 

Under the title ‘OLED, Yesterday, Today, and Tomorrow’, the forum attendees could review Korean OLED research results of the past 20 odd years, and discussed regarding future OLED industry growth strategy.

 

LG Display’s CTO In-byeong Kang gave a presentation on Large Area OLED Status and Future and talked about the current status and forecast of large area OLED which is expected to become the key area of future display.

 

Since the mass production of first 55 inch OLED panel that utilized WRGB method and oxide TFT, 3 years went past. During those 3 years, Kang revealed that many innovations were carried out in terms of TFT device, compensation algorithm, OLED device, OLED materials, and processes.

 

First, the oxide TFT structure changed to coplanar method from etch stopper method, and for compensation wiring, the internal compensation was changed to external compensation. Also, he revealed that through much effort, the existing OLED device and materials were changed to new structure and high efficiency and high color gamut OLED emitting materials. Kang added that the uniformity, which becomes the most crucial point in large area OLED panel mass production, was greatly improved in Gen8 manufacturing equipment.

 

In 2013, there was only 1 LG Electronics’ OLED TV, 55 inch FHD, but recently 77 inch and 65 inch were added, and the resolution increased to UHD. Kang emphasized that although the 2013 product was priced at 11 million KRW with 100/400 nit of brightness but recent products have brightness of 150/450 nit at the reduced price of 4.2 million KRW.

 

LG Display is going through many changes recently. OLED business department began operation from last year. Large area OLED panel, which started with 8K monthly mass production at Gen8, is now being produced at 26K in full operation. Also, additional investment of 10 trillion KRW to large area panel has been decided, and new factory is being built in Paju. Kang told the audience that he heard many positive views on large area OLED at CES, and that there was a huge response regarding the 77 inch HDR video. Kang revealed confidence in the technology reporting that rather than replacing LCD, OLED could succeed as a totally different display.

 

Regarding the next 20 years, Kang forecast that the flat will move toward transparent and flexible, and OLED is the most suitable for this. He explained that the Korean government estimated this and is carrying out national project titled ‘≥60 inch UHD level transparent flexible display and applicable IT fused infotainment system development’ for the past 4 years. LG Display is responsible for this project’s overall consortium, and is planning to reveal UHD level 60 inch transparent flexible OLED panel in 2017 summer when the project is complete.

 

At the end of the presentation, Kang summarized 3 innovation factors for large area OLED. First, the substrate materials at Gen8 has to change to PI and transparent PI. Second, even for flexible substrate, the structure has to change to top emission from bottom emission, and lastly, Kang added that much more diverse applications have to be considered for flexible panel.
