4.4L: <i>Late‐News Paper:</i> Novel OLEDs for Full Color Displays with Highest Power Efficiencies and Long Lifetime

Abstract

Abstract Top emitting PIN‐OLEDs that are perfectly suited to full color displays are reported here. For red, green, and blue diodes, power efficiencies at 1000 cd/m 2 of 11 lm/W, 70 lm/W, and 8.4 lm/W were achieved. Lifetimes of phosphorescent bottom emitting PIN‐OLEDs of 30,000 hours at a brightness of 500 cd/m 2 indicate that charge carrier doping allows for very high lifetimes. Even higher stability could be achieved by replacing Cs with the new molecular n‐dopant NDN‐1. Furthermore, a white bottom emitting OLED (color coordinates (0.35, 0.37), CRI of 95) with a power efficiency of 16.3 lm/W at 1000 cd/m 2 is shown.
