Title (EN) BAND EDGE EMISSION ENHANCED ORGANIC LIGHT EMITTING DIODE UTILIZING CHIRAL LIQUID CRYSTALLINE EMITTER
(FR) DIODE ÉLECTROLUMINESCENTE ORGANIQUE AMÉLIORÉE D’ÉMISSION EN BORD DE BANDE UTILISANT UN ÉMETTEUR CRISTALLIN LIQUIDE CHIRAL
Abstract:
(EN) 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.
(FR) La présente invention décrit un dispositif électroluminescent et un procédé de fabrication d’un tel dispositif composé d’une série de couches cristallines liquides chirales, photopolymérisables, qui peuvent être coulées au solvant sur un substrat. Le mélange des matériaux chiraux dans chaque couche successive peut être effectué d’une manière telle que chaque couche présente le même pas chiral. En outre, les matériaux chiraux dans chaque couche peuvent également être mélangés afin que les indices de réfraction ordinaire et extraordinaire dans chaque couche correspondent aux autres couches de sorte que l’ensemble complet des couches fonctionnera de manière optique comme couche unique relativement épaisse de cristal liquide chiral. Le matériau nématique chiral dans chaque couche peut spontanément adopter une structure hélicoïdale avec un pas hélicoïdal. Les couches d’émission de lumière du dispositif d’émission de lumière peuvent en outre comprendre un matériau électroluminescent qui émet de la lumière dans les modes de propagation de lumière en bord de bande du cristal photonique.
