UBI Research, ‘2018 OLED KOREA Conference’ will be held on 7th to 8th of March

OLED Korea Conference, the global OLED conference, will be held on 7th(Wed) to 8th(Thu) of March.

The 4th OLED Korea Conference will be held on the theme of ‘OLED with opportunity & adding value to your business’ at the Novotel Ambassador Hotel in Seoul, Korea for two days. It is expected to provide a platform for various information and exchange of opinions regarding presentation of each theme.

OLED industry, which is continuing to grow at a high rate is expected to surpass the LCD market share in the small and mid-sized market of this year.

According to UBI Research, the OLED research organization, small and medium-sized OLED panel shipments for mobile devices are expected to grow up to 6.3 billion won in this year, which is 53.2% growth compared to last year. On the other side, OLED panel shipments for TV is expected to grow up to about 2.4 million won which is 47.2% growth compared to last year.

In this conference, there will be presentations on the topic; ▲ View from Panel Makers about OLED Market ▲ Solution Process Technology, yet to come ▲ New Performance Development from Major SCMs ▲ New Technology Discussions for Next Generation Display or Better Process from global companies such as Microsoft, Boeing, Sony and leading companies such as 3M, Applied Materials, Corning, Cynora and OLED panel company, set company, material/device company, university/research institute as well as domestic and foreign experts of OLED display.

Also, UBI Research, Japan Mizuho Security and French market research institute ‘Yole development’ planned a lecture about the title of “Opinion from Business and Industry Analysts.”

Especially, Yoshihiro Ono, TV business manager from Sony will present about OLED TV launch for the first time in Sony, which was one of the biggest issues in OLED industry of 2017. The title is ‘Designs for BRAVIA OLED TV and Expectations for large screen OLED devices’ and contents are about adoption background, BRAVIA OLED TV development history and different points of OLED TV from other companies.

In the 4th OLED KOREA Conference which will show trends and developments of OLED industry, it is expected that more than 200 major domestic and foreign experts and industry workers will participate. This conference has received much attention as it is planned to provide opportunities for networking and continuous exchanges of relevant information and know-how.

Is there possibility of High resolution(UHD) OLED Smart-phone generation?

Recently VR contents experience through smart-phone device has been increased, therefore high resolution of smart phone is becoming necessary. However, OLED smart-phone resolution still remains at QHD level for 3 years since QHD OLED is applied to Galaxy Note 4 for the first time in 2014.

The core point that decides resolution of OLED smart-phone is evaporation process for emission layer. Bottom-up type evaporation method, which is applied to the recent devices is that substrate and FMM (fine metal mask) are horizontally arranged on the upper side of evaporator and vaporize the organic material from the lower linear source in order to form RGB layer.

Thin FMM measures less than 15um thick is necessary for making high resolution OLED like UHD level, however, as FMM gets thinner, it would be difficult to make mass production because technical problems will be occurred such as patterning, sealing and welding.

In order to solve these problems, various metal mask patterning technologies are being developed such as vertical type evaporation and plane source evaporation.

Vertical type evaporator that arranges board and FMM vertical is developed by Hitachi of Japan for the first time. And Canon Tokki exhibited Gen6 vertical type evaporator at Finetech Japan 2013, however it is not being used for mass production at the moment.

According to the recent ETNEWS, Applied Materials developed Gen6 flexible OLED vertical type evaporator and it is being tested in Japan Display.

Plane source evaporator is being tested but also the linear source type. Plane source evaporator method is that an organic material is first evaporated on the metal surface to produce plane source, then re-evaporated in order to form an organic thin film on the substrate.

In the past iMiD 2017, representative of OLEDON, Chang Hoon Hwang mentioned that 2250 ppi resolution OLED can be implemented through plane source evaporator.

For metal mask patterning technology, electro forming and laser patterning technology is highlighted. Electro forming method is developed by Wave Electronics, TGO Technology, Athene and so on. Laser patterning technology is being developed by AP Systems.

As such, development for high resolution OLED is receiving great attention whether it can solve the current problems and contribute to UHD resolution implementation for OLED smart-phone.
