We present a 15 cm × 15 cm PHOLED TM lighting panel that operates with 50 lm/W efficacy, CRI = 87, CCT = 3055 K and lifetime to LT70 ≅ 10,000 hrs at 1,000 cd/m 2 . We also present a panel with 58 lm/W efficacy, CRI = 86 and CCT = 2790 K at 1,000 cd/m 2 , and a small‐area lighting pixel with 109 lm/W efficacy, CRI = 80, CCT = 3295 K and lifetime to LT70 ≅ 15,000 hrs at 1,000 cd/m 2 . A highly stable light blue phosphorescent host‐emitter system is used to reduce power consumption, extend operational lifetime and demonstrate exceptional emission color stability with aging.
