Abstract

To minimize the influence of the refractive index mismatch between transparent conductive layer (e.g. Indium Tin Oxide (ITO)) and glass substrate on the light outcoupling efficiency (LOE) of organic light emitting diode (OLED), in this paper, we present a blue OLED with high LOE by incorporating a layer of tilted nanotube array as an internal light extraction structure in an optimal location. In comparison with conventional planar OLED, the LOE can be increased from 10.9 to 55.3%. The increase in LOE is mainly due to the strong disruption of waveguided mode. The tilted structure can be potentially used to develop high efficiency OLEDs.
