Seiko Epson sees 37" (and larger) inkjet-printed OLED TVs in 2012
Last month Seiko Epson has unveiled a new inkjet-printing technology for OLEDs, suitable for large sized panels. We have talked to Satoru Miyashita, General Manager of Seiko Epson's Core Technology Development Center about this new technology and their plans for OLED production.
Q: You have shown a new ink-jet based OLED technology. You say it will enable 37" or larger HD-OLED TVs. Do you have any plans to actually make such TVs? When do you think products can be made with this new tech?
Q: Will the new printing technology also allow OLED lighting panels? Or is it just for displays?
Q: Back in 2004, you signed an agreement with Universal-Display to co-develop inkjet OLED printing. Is the new tech part of this agreement? Are you using PHOLED materials or IP?
Epson's relationship with UDC is still strong and research is ongoing, and we published a paper at SID 2009 on P2OLED small molecule systems with UDC's assistance.
This paper is about the status of Printed OLEDs. Epson says that the biggest issues with printed OLEDs has been significantly improved. They give examples of a polymer-based OLED device with 45,000 hoursl lifetime, and a phosphorescent small-molecule system that has 40 cd/A efficiency.
Q: In 2007 you said you will begin to make OLED panels (the aim there was to make large 8" panels). Is this still on track? Will Seiko-Epson be making medium sized panels? When?
Q: Are you working on other OLED technologies? or are you focusing on Inkjet printing?
Mr Satoru, Thank you very much! I hope we'll see large sized OLED TVs by Epson soon, maybe even before 2012...
