The achievement of a green PIN PHOLED(TM) 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-OLED(TM) technology and doped transport materials.
"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.
