Abstract

The invention discloses an integrated light conversion glass diffusion plate and a preparation method thereof. The integrated light conversion glass diffusion plate comprises a glass substrate, a diffusion layer, a quantum dot light conversion layer, a bonding layer and an optical film, wherein the diffusion layer is arranged on the light emitting surface of the glass substrate, the quantum dot light conversion layer is attached to the diffusion layer, and the optical film is bonded to the quantum dot light conversion layer through the bonding layer; the diffusion layer is formed by coating the light diffusion material on the glass substrate and performing curing; the light diffusion material comprises the following components in percentage by weight: 45-55% of resin, 30-40% of diffusion particles, 10-15% of diluent and 1-5% of silane coupling agent, and the quantum dot light conversion layer is formed by making quantum dots dispersed in silica gel ink or UV glue, coated on the diffusion layer and cured. According to the integrated light conversion glass diffusion plate disclosed by the invention, the quantum dots are integrally embedded into the glass diffusion plate, so that theuse of quantum films is reduced, the cost is reduced, and the product thickness is smaller. The integrated light conversion glass diffusion plate is high in color gamut, the color gamut is improved by30% by embedding the quantum dot light conversion layer, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of diffusion plate preparation, in particular to an integrated light conversion glass diffusion plate and a preparation method thereof. Background technique [0002] Traditional diffusion plates usually use PMMA, PC, PS, PP and other substrates to add inorganic or organic light diffusing agents as scattering particles, so that light is continuously refracted in two media with different refractive indices when passing through the scattering layer. Reflection and scattering, so as to change the path of light, and realize the sufficient scattering of incident light to produce the effect of optical diffusion. However, plastic materials such as PMMA, PC, PS, PP, etc., all have the common characteristics of hygroscopic expansion, heat bending, and cold contraction. , the material is soft, and the supporting force is not enough to easily cause the front arch and the back warp. [0003] The light source of the dif...
