Embodiment Construction
[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] A multifunctional composite board, comprising a light-incident layer 1, an intermediate layer and a light-exit layer 4, the light-exit layer 4 is composed of quantum dot concentrate and UV glue, the weight ratio of quantum dot concentrate to UV glue is 1:10000, and the UV glue After curing, the surface plays the role of blocking and protecting the quantum dots. When the light passes through the light-emitting layer, the quantum dots inside are activated, thereby achieving a significant brightening effect. The cured UV glue isolates the quantum dots from air and moisture, prolonging the life of the composite board. service life and use effect.
[0022] The light incident layer 1 is composed of optical grade GPPS, light diffusing agent, anti-yellowing agent and antistatic agent. The anti-yellowing agent is composed of ant...

Abstract
The invention provides a multifunctional composite board. The multifunctional composite board comprises a light incident layer, a middle layer and a light emitting layer, wherein the light emitting layer is composed of quantum dot concentrated liquid and UV glue, and the weight composition ratio of the quantum dot concentrated liquid to the UV glue is 1: 10000. The light diffusion board provided by the invention comprises the light incident layer, a light guide layer, a diffusion layer and the light emitting layer, the light incident layer enhances the yellowing resistance of the product, andthe light passing uniformity is improved; the light guide layer can improve the stiffness and toughness of the product; the diffusion layer further improves the uniformity of light; and the light emitting layer can improve the brightness of the product. The invention further provides a manufacturing method of the light emitting layer, a thin high-transparency film layer is formed on the surface ofthe middle layer, then the brightness of the product is improved, meanwhile, the method is simple, and the service life of the product is prolonged.
Description
technical field [0001] The invention relates to the field of composite boards, in particular to a multifunctional composite board. Background technique [0002] The light diffusion plate is a physical phenomenon of refraction, reflection and scattering that occurs when the light encounters two media with different refractive indices on the way through chemical or physical means. The light diffusion plate makes the light refract and reflect in different directions. and scattering, so as to change the path of light and realize the sufficient dispersion of incident light to produce the effect of optical diffusion. Light diffusion plates are widely used in liquid crystal display, LED lighting and imaging display systems. [0003] The light transmittance of the existing light diffusion plate is poor, and the light diffusion degree is low. When the brightness of the light diffusion plate is not enough, the brightness is usually increased by increasing the number of light bulbs. Th...
