Abstract

An approach to increase the coupling efficiency of organic light emitting diodes (OLEDs) is studied. Refractive microlens arrays are formed on the high refractive index glass substrate by etching the glass using reflowed photoresist as mask. Over 65% more light is extracted from the OLED on the microlens array substrate as compared with the conventional device, without affecting the electrical performance. No color variation is induced by the microlens array.
