45.2: <i>Invited Paper</i> : Extremely High Performance White OLEDs for Lighting

Abstract

Abstract High performance all phosphorescent white devices with single unit and two‐unit structures on a light outcoupling substrate were investigated. The single unit device showed high efficacy of 87 lm/W with a half decay lifetime of 10,000 h at the luminance of 1,000 cd/m 2 . The two‐unit device realized also high efficacy of 83 lm/W with much improved lifetime of over 100,000 h.
