61.2: Phosphorescent Stacked OLEDs for Warm White Lighting Applications

We report record lifetime for an all‐phosphorescent stacked white OLED pixel with an extended lifetime to LT70=25,000 hours at L0=3,000 cd/m2 with 1.72x external outcoupling enhancement and a power efficacy of 60 lm/W. This warm white device meets En ergy Star criteria with CIE 1931 (x, y)=(0.452, 0...

Zusammenfassung:We report record lifetime for an all‐phosphorescent stacked white OLED pixel with an extended lifetime to LT70=25,000 hours at L0=3,000 cd/m2 with 1.72x external outcoupling enhancement and a power efficacy of 60 lm/W. This warm white device meets En ergy Star criteria with CIE 1931 (x, y)=(0.452, 0.420), CCT=2,882K, CRI=83, and demonstrates exceptional color stability as a function of luminance and aging.
