Paper Abstract

We present a 7.5 cm x 7.5 cm white PHOLEDTM lighting panel that delivers 1,000 cd/m2 with 68 lm/W efficacy, CRI > 80 and lifetime to LT70 ≈ 15,000 hrs. A simple all-phosphorescent device architecture, including a highly stable light blue phosphorescent emitter-host system, is used to reduce panel power consumption, extend operational lifetime and demonstrate exceptional emission color stability with aging.
