Abstract
A display device that uses one or more light coupling layers is described herein, along with methods of making such devices. One device includes an array of blue light emitting elements formed on a substrate, a light coupling material formed over the array of blue light emitting elements, and a quantum dot light converting material disposed in a portion of a pixel structure formed over the array of blue light emitting elements. The light coupling material has a high refractive index and may be, or include, a polymer material.

A display comprising:
- an array of blue light emitting elements formed in a pixel structure having subpixels;
- a plurality of quantum dot light converting materials disposed on a portion of the subpixels;
- and
- a light coupling material having a refractive index of at least 1.6 formed on top of the quantum dot light converting materials.
A display comprising:
- an array of blue light emitting elements formed in a pixel structure having subpixels;
- a light coupling material comprising aromatic components and having a refractive index of at least 1.6 disposed over the array of blue light emitting elements;
- a plurality of quantum dot light converting materials disposed on a portion of the sub-pixels;
- and
- a light transmissive top formed over the quantum dot light converting materials.
A method of making a display, comprising:
- forming a pixelated blue light emitting structure on a first substrate;
- forming a patterned layer of quantum dot materials on a first portion of a second substrate;
- forming a patterned layer of light conditioning material on a second portion of the second substrate;
- forming a light coupling material having aromatic components, hetero atoms, or both, and a refractive index of at least 1.6 over the quantum dot material and the light conditioning material;
- and
- attaching the light coupling material of the second substrate to the pixelated blue light emitting structure of the first substrate.
