US Patent 7671531 Organic electroluminescent device with enhanced light emission

An organic electroluminescent device is provided which includes a colored polarizer to reduce power consumption requirements for desired levels of brightness. The organic electroluminescent device includes a substrate, an anode electrode layer, an organic layer, a cathode electrode layer, and a colored polarizer provided on a surface of the substrate opposite a surface of the substrate on which the anode electrode layer is formed such that the colored polarizer polarizes light incident from the outside. The colored polarizer increases transmission of a given color of light based on the color(s) included in the polarizer to thereby decrease total current required by the organic electroluminescent device.
