Title:
QUANTUM DOT SUBSTRATE, PREPARATION METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/011675
Kind Code:
A1
Abstract:
The present application discloses a quantum dot substrate, a preparation method therefor and a display apparatus. The quantum dot substrate comprises a quantum dot film. The quantum dot film comprises quantum dots and first nanoparticles dispersed between the quantum dots, the particle size of the first nanoparticles being 2 nm-50 nm. In the present application, by means of disposing first nanoparticles having a particle size ranging from 2 nm-50 nm between the quantum dots, the self-absorption phenomenon of the quantum dots is reduced, and the luminous efficiency of the quantum dots is increased.
