Abstract

A top emitting OLED display includes a substrate; a patterned electrode formed above the substrate, defining a plurality of light emitting elements having gaps between the light emitting elements; a layer of OLED material disposed above the patterned electrode; a continuous transparent electrode disposed above the layer of OLED material; and a light-absorbing auxiliary electrode that is thermally and electrically conductive and in electrical and thermal contact with the continuous transparent electrode and located over the gaps between the light emitting elements of the display.
