Title:
BAND EDGE EMISSION ENHANCED ORGANIC LIGHT EMITTING DIODE UTILIZING CHIRAL LIQUID CRYSTALLINE EMITTER
Document Type and Number:
WIPO Patent Application WO/2017/156433
Kind Code:
A8
Abstract:
Disclosed herein is a light emitting device and method of manufacturing such a device comprised of a series of photopolymerizable, chiral liquid crystalline layers that can be solvent cast on a substrate. The mixture of chiral materials in each successive layer may be blended in such a way that each layer has the same chiral pitch. Further the chiral materials in each layer may also be blended so that the ordinary and extraordinary refractive indices in each layer match the other layers such that the complete assembly of layers will optically function as a single relatively thick layer of chiral liquid crystal. The chiral nematic material in each layer can spontaneously adopt a helical structure with a helical pitch. The light emitting layers of the light emitting device can further comprise electroluminescent material that emits light into the band edge light propagation modes of the photonic crystal.
