摘要：

In this work we report exceptional efficacy, lifetime and color stability for all-phosphorescent white stacked organic light-emitting devices (SOLED (R) s). We report data for all-phosphorescent white SOLED pixels with two emissive units connected in series by a charge generation layer (CGL). At 3; 000 cd/m(2), efficacy = 54 to 56 lm/W and lifetime to 70% of initial luminance LT70 approximate to 20; 000 h, with color rendering index (CRI) = 82 to 83 and chromaticity meeting Energy Star criteria. We further report data for a 15 cm x 15 cm white SOLED panel that operates at 3; 000 cd/m(2) with 48 lm/W efficacy, CRI = 86 and chromaticity meeting Energy Star criteria. The panel has extremely low operating temperature that is only 6.4 degrees C above ambient, and exceptional lifetime of LT70 approximate to 13; 000 h when operated at 3; 000 cd/m(2).
