Abstract :
This paper describes a top-emitting OLED structure that implements both low ambient light reflection within the OLED structure and reasonable emission efficiency. Ambient light reflection from a top-emitting device can be effectively suppressed by using a moderate bottom reflector and top antireflection coating, meanwhile retaining acceptable EL efficiency and other viewing characteristics for display applications.
