Popis:	We present an all-phosphorescent warm white OLED pixel with a high efficacy of 63 lm/W and an extended lifetime to LT70=10,000 hours at 3000 cd/m2. This device has an Energy Star white color with CIE 1931 (x, y) = (0.469, 0.428), CCT=2703K and a high CRI=89. We also present a PHOLED pixel for potential cooler white lighting applications with CIE 1931 (x, y)=(0.352, 0.369), and CCT=4809K. At 1000 cd/m2 the power efficacy=57 lm/W.
