CYNORA focuses on blue TADF-materials

/0 コメント/カテゴリ: , , /作成者:

During the 2nd OLED Korea Conference, the Germany-based CYNORA has presented its current status in blue TADF-based OLED-emitter development.

CYNORA focuses on materials that are able to convert triplet excitons into light via Thermally Activated Delayed Fluorescence (TADF).  While efficient emitters for red and green are already commercially available from other suppliers, there is still no blue OLED material available to match the strong demand for the industry. TADF technology is a promising candidate for highly efficient and stable blue emitter systems. TADF-based emitters offer up to four times better efficiency than currently used materials, which are based on fluorescence.

CYNORA has shown its current TADF-materials for sampling with good color points in blue (CIE 0.16, 0.17) and sky-blue (CIE 0.19, 0.36). The presented materials confirm that blue emission and high efficiency can be combined. CYNORA is focusing its current material development on vacuum-processing following the customer request, as represented in large investments into this deposition technology by the major AMOLED displays makers.

In order to provide more sample materials to customers, while reducing the cycle times for material improvements, CYNORA is growing its infrastructure. The company is extending the device testing capacity by setting up a new cluster tool and hiring continuous experts for the synthesis and device department. Due these actions CYNORA’s emitter throughput will increase significantly.

The strong interest from the OLED industry in TADF-based blue emitters systems has been once more confirmed at this UBI event and allowed CYNORA to further extend its network with the Korean OLED community.  The present expansion of CYNORA management operations, consistently sampling and improvement of blue OLED materials are further strengthening the position of CYNORA as a technology leader in the field of TADF emitter systems.

[2nd OLED KOREA Conference] Samsung Display, Future Display’s Virtue is Design Freedom

Insun Hwang, Samsung Display’s principal engineer of the Frontier Technology Team, announced that as the display market is expanding, the key factor for positive outlook for future display is ‘design freedom’.

 

At the 2nd OLED KOREA Conference (Feb 24-25) hosted by UBI Research, Hwang gave a keynote presentation.

 

During the presentation, Hwang announced that the mobile overtook TV as the medium that people use to access daily media. According to the presentation materials, the mobile usage is increasing each year, while the TV usage is decreasing. Also as the mobile usage of people under 50 is higher than that of TV, Hwang forecast that the number of people using mobile to access information will increase. He added that if the display panel price falls down, the number of the display panels will become higher than the number of users and forecast positive future for the display market.

 

Hwang particularly mentioned that AMOLED applied products will increase as it emits less harmful blue light and is human friendly, giving smartwatch and VR as the current examples. He estimated that the smartwatch market can expand through differentiated strategy with new functions and designs. Additionally, as an issue that needs to be solved, he mentioned that the resolution of VR falls as the distance between the user and display is short. High resolution is the key in VR, and Hwang explained that approximately 2,000 ppi is required for suitable realism. He also forecast that the automotive display will lead the display field and the future market. He further explained that as OLED can actualize the curvature and transparency, it is appropriate for automotive display.

 

However, Hwang also mentioned OLED’s lack in technology. Pointing out that technology for plastic window, flexible touch, encapsulation, and backplane falls short of what the market requires for flexible display and design freedom, Hwang described the need for OLED technology development.

 

Hwang estimated many flexible display equipped smart products in future, and concluded that display’s design freedom will be the most important issue.

[2nd OLED KOREA Conference] Looking at the Future Through Display Trend

Choong Hoon Yi, the president of UBI Research, discussed the trend change of CES 2016 and the effects on future OLED display and market forecast.

 

During the 2nd OLED KOREA Conference (Feb 24 – 25), Yi gave a key note presentation titled ‘Dynamic Change in OLED Industry’.

 

Discussing CES 2016, Yi first gave VR and drones as display related hot issues. However, he defined the 2 products as items that bring enjoyment to the users rather than products that are necessary in everyday life. Yi estimated that the market is expected to grow but with some limitation.

 

The second issue Yi gave was automotive display which he forecast significant growth as dashboard attachment from the exhibitions by automotive and related companies that became more prominent since the last CES. Volkswagen particularly drew attention with IoT function attached dashboard display that can control electronic appliances at home. Additionally, Hyundai Mobis and Denso embedded display for side mirror use on the dashboard.

 

Yi reported that in CES, for TV section which is the most important home appliances, LG Electronics’ OLED TV decidedly stood out. At CES 2016, LG Electronics impressed the viewers by actualizing the blackness of the space and fiery sun filmed by NASA. Samsung Electronics exhibited existing SUHD TV with quantum dot display. Japanese companies such as Panasonic and Sony presented LCD panel applied TV.

 

Additionally, Yi told the attendees that Samsung’s transparent OLED using Galaxy Gear promotion and LG’s dual-view curved tiling OLED promotion of various home appliances were impressive. He added that these exhibitions were only possible by companies currently producing OLED. Forecasting that OLED market will exceed 1,000 million units of shipment in 2020 and mentioning investment forecast following this, Yi concluded his presentation.
