Method for increasing the light output of microled devicecs using quantum dots

Abstract

Illumination devices based on quantum dot technology and methods of making such devices are described. An illumination device includes a substrate having a plurality of microLEDs, a beam splitter, and a film having a plurality of quantum dots. The beam splitter includes a plurality of layers and is disposed between the substrate and the film having the plurality of quantum dots.

What is claimed is: 
     
         1 . A method of fabricating an illumination device, the method comprising:
 forming a plurality of microLEDs on a substrate;   disposing a continuous layer of beam splitter over the plurality of microLEDs, wherein the beam splitter comprises a plurality of stacked layers; and   disposing a film comprising a plurality of quantum dots over the beam splitter.
