AI Technical Summary

Technical Problem

Existing Micro LED full-color display technology suffers from optical crosstalk, especially when using quantum dot materials for color conversion to achieve full-color display. Quantum dot films have poor high-temperature resistance and poor resistance to water and oxygen, resulting in high costs and severe crosstalk.

Method used

A barrier layer and a metal barrier are set on a transparent substrate to form an integral barrier to accommodate quantum dots. The metal barrier reflects light to reduce lateral crosstalk between quantum dots. A groove array design in the shape of a convex lens is used to concentrate light and reduce optical crosstalk.

Benefits of technology

It effectively reduces optical crosstalk between quantum dots, improves display effect and reliability, reduces cost, and enhances high temperature resistance and water and oxygen resistance.

Abstract

The present disclosure provides a color conversion structure preparation method, a color conversion structure and a display device. The method comprises: providing a transparent substrate; disposing a partition layer on the transparent substrate and opening a first contact hole array on the partition layer, so that each first contact hole exposes a corresponding preset exposed portion on the transparent substrate; disposing a resin layer on the partition layer and opening a second contact hole array on the resin layer, so that the second contact hole exposes at least part of the partition layer, and the resin layer comprises a first groove array; disposing a passivation layer on the resin layer and opening a third contact hole array on the passivation layer, so that the third contact hole exposes at least part of the partition layer, wherein the passivation layer comprises a second groove array; disposing a metal partition on the exposed part of the partition layer; filling quantum dots in the second groove array to form a quantum dot array, thereby obtaining a color conversion structure.
