Optimization of light extraction from OLEDs.

Author information

Philips Research, High Tech Campus 36, 5656 AE Eindhoven, The Netherlands.


In recent years, many methods were developed to improve the efficiency of an OLED. In this paper, we investigate the effects of some main factors contributing to the extraction efficiency. These factors include the polarization of the source, the distance between the source and the metal, and the thickness of the layers. We will also discuss the effect of periodic patterns such as a grating structure.
