What's Next in Flat Panel Display Technology?

Ahead of their participation in the 2018 OLEDs World Summit, we reached out to Dr. Fan Xing, Senior Research Engineer at BOE, and Dr. Longjia Wu, Materials Development Expert at TCL Corporate Research, to get their take on what's in store for the future of flat panel display development, the shared challenges and opportunities that exist among competing display technologies, and the value of attending the OLEDs World Summit in 2018.

Smithers Apex: Why is this meeting important to those working in the OLED industry?

Dr. Xing: The OLEDs World Summit has a long history and is very famous all over the world. To support this event, BOE can show what we have accomplished recently and communicate with the top experts and companies of the global industry chain about the newest hot spots in OLED.

Dr. Wu:   This meeting is especially designed for the OLED lighting and display industry. People working in this area could expect to build connections with other leading experts in the OLED industry and learn about the latest developments. That's why this meeting is important to them.

Additionally, QLED technology is derived from the OLED industry, and they are identical in many aspects, like similar device structure and charge transport materials. Therefore, we like to share our thoughts and the recent progress on QLED display in this conference and expect to have some deep discussions with the leading experts in the OLED industry.

Smithers Apex: What does TCL hope to accomplish over the next few years with regard to QLED Technology?

Dr. Wu:    In the next few years, TCL would like to push the QLED technology to meet the requirement of display applications, since QLEDs are the future of QD display. To achieve this, we need to greatly improve the performance of QLEDs, especially on the operation lifetime.

Smithers Apex: In a similar context, what does BOE hope to accomplish over the next few years with regard to OLED display technology?

Dr Xing:   BOE will have G2.5 flexible AMOLED test line in Beijing, G5.5 Rigid AMOLED MP line in Ordos, G6 Flexible AMOLED MP line in Chengdu, Mianyang and Chongqing and G4.5 test center for engineering technologies in Chengdu in the next few years.

This R&D covers the technology and application of Full Screen, Flexible/Rollable, VR, Automobile, Transparent, Notebook, etc. BOE intends to cooperate with ally vendors and clients to promote development of the OLED industry all over the world.

Smithers Apex: What are you most looking forward to hearing at this year's OLEDs World Summit in September?

Dr. Xing: I want to hear latest technological breakthroughs and development strategies of the newest products being discussed at this event.

Dr. Wu:   Ink-jet printing is an ideal technology for OLEDs fabrication, reducing the fabrication cost and suitable for large-area OLED displays. And it is very promising to be the final solution of QLED fabrication. Therefore, I am looking forward to hearing any progress on ink-jet printing technology concerning OLED/QLED fabrication. Meanwhile, the topic about how to improve the color gamut of OLED on “deep blue” color area while maintaining the high device efficiency is also worthwhile to be addressed.

Smithers Apex: Dr. Xing, why do you think people should attend the OLEDs World Summit?

Dr. Xing: People can find everything about OLED technology in this event and it is a great opportunity to learn from each other and communicate with each other to boost the OLED industry.

Smithers Apex: And Dr. Wu, why do you think people should attend the OLEDs World Summit, and how are QDs important to the OLED market?

Dr. Wu: As I mentioned above, people in the OLED industry should attend this conference to build connections with the leading experts in this area and learn more about the latest innovations. As for the second part of the question, QLED and OLED are similar to each other in many aspects, so the development of OLED technology could be inspired by the latest progress of QLED and vice versa. That’s why QDs are also important to the OLED market.

Smithers Apex:  What are some of the industry challenges that this year’s conference will address?

Dr. Xing:  The problems and the solutions of New materials, printed OLED and foldable OLED from R&D to industry.

Dr. Wu:   As I mentioned before, the progress in ink-jet printing technology concerning OLED/QLED fabrication and the methods to improving the device efficiency of OLED at “deep blue” color area should be addressed.
