The light distribution in OLEDs and ways to increase the light outcoupling efficiency

Abstract
Power efficiency of organic light emitting devices (OLEDs) is in the focus of worldwide research in order to reduce power consumption of displays and to improve the competitive situation of OLEDs for lighting devices. The optical properties of OLEDs are studied with the aim to enhance the fraction of light coupled out of these devices. Simulation software has been used to analyze the transfer of internally generated emission into usable external light modes. Results from modeling have been compared to experimental data to build trust into the validity of the results. Critical parameters influencing outcoupling properties have been identified. Thus, 185lm/W at 1000cd/m2 have been achieved for a green PIN-OLED using a high-n substrate & half ball lens. Finally, some conclusions for the design of outcoupling enhancing means are drawn.
