Prerequisite for a wide market penetration of AM OLED displays are price competitiveness and superior performance in comparison with rival flat panel display approaches. In this talk, top emitting Novaled PIN OLED™ architectures will be presented that allow for lifetimes exceeding 100,000 hours at 500 cd/m 2 . At this brightness, novel OLED materials enable 17,000 hours operating lifetime even at an elevated temperature of 80 °C. For a green top‐emitting OLED, a current efficiency of 95 cd/A (1000 cd/m 2 ) at a very low voltage of 2.55 V is shown.
