P-157: Improved Light Extraction from Organic Light-Emitting Diodes using High Refractive Index Nanostructure

Highly enhanced performance OLEDs have been demonstrated by high refractive index nanostructure (HRIN). The HRIN scatters the waveguided light and extracts the light into the air. From these properties, the enhancement ratio of the devices with HRIN corresponds to 59.06% in current efficiency and 54.83% in external quantum efficiency.
