Title:
QUANTUM DOT LIGHT DIFFUSION PANEL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/173820
Kind Code:
A1
Abstract:
Provided in the present invention are a quantum dot light diffusion panel, a preparation method therefor and the use thereof. The quantum dot light diffusion panel of the present invention uses, as a light diffusion layer, polystyrene (GPPS) into which a light diffusion agent master batch and a quantum dot master batch are added, and a protection layer is compounded on each of the upper surface and the lower surface of the light diffusion layer; and each protection layer is a PMMA resin layer subjected to blending modification by an SMA resin and an EAA resin, thus effectively improving an interlayer bonding force between the PMMA resin layer and the GPPS layer which are made of two different materials, and further remarkably prolonging the service life of the material. The quantum dot light diffusion panel of the present invention has a total light transmittance that is higher than 40% and can be as high as 60%, has a haze that is higher than 85% and can be up to 97%, and has a surface hardness grade that can be up to grade 2H; and after 600 hours of irradiation, a light aging color difference value of the quantum dot light diffusion panel reaches a level of △E≤1.5 and can be as low as 0.5.
