OLED-TV Display/Monitor Technology News

Novaled will present latest achievements of PIN OLED development at IDMC 2007 in Taipei, Taiwan, among them outstanding results in lifetime for green bottom emission PIN OLEDs with more than 200,000 hours at an initial brightness of 1,000 cd/sqm and very low driving voltages.

Recent advances of its Novaled PIN OLEDTM technology combining longest lifetimes of green phosphorescent OLEDs and low driving voltages will be presented by Dr. Tobias Canzler, Novaled project manager, at the IDMC 2007. The achievement of a green PIN PHOLEDTM phosphorescent OLED device in bottom-emission geometry with a CIE of (0.36, 0.61) of above 200,000 hours were attained by combining Universal Display’s high-efficiency phosphorescent OLED materials with low-voltage Novaled PIN-OLEDTM technology and doped transport materials.

“This achievement demonstrates that the Novaled PIN OLEDTM not only provides very good lifetime results, but in addition is the most suitable approach for reaching lowest operating voltages ”, states Jan Blochwitz-Nimoth, CTO of Novaled.

“We expect that very low driving voltages below 2.6 V which we already achieved for Ir(ppy)3 can also be obtained for other phosphorescent green emitters” adds Jan Birnstock, VP Technology Transfer.
