High contrast sphere-supported thin-film electroluminescent devices

摘要

A two layer AR coating system for improving the contrast ratio of SSTFEL and Nixel devices. It is composed of an ITO layer and ultra-thin gold layer deposited on the surface of the EL devices. Thus the antireflection layer for a flexible emissive electroluminescent (EL) device comprises a layer of indium tin oxide (ITO) covering the surface of a flexible emissive electroluminescent device, and a layer of metal on top of the layer of indium tin oxide covering the surface of a flexible emissive electroluminescent device. The thicknesses of the layers may be adjusted to give destructive interference.
