Abstract

The invention relates to a quantum dot diffusion plate for preventing heat dissipation of quantum dots, and a manufacturing method thereof and a backlight module, the quantum dot diffusion plate comprises a light-transmitting diffusion plate body and a plurality of pre-sealed diffusion colloidal particles dispersed in the light-transmitting diffusion plate body, and the pre-sealed diffusion colloidal particles are basically composed of light-transmitting plastic and a light diffusion agent, a reflecting agent and a quantum dot body dispersed in the light-transmitting plastic. The pre-sealed diffusion colloidal particles are in homogeneous phase distribution in the light-transmitting diffusion plate body, and the quantum dot bodies are in heterogeneous phase distribution in the light-transmitting plastic; and when the light-transmitting diffusion plate body is subjected to extrusion molding, the upper surface and the lower surface of the light-transmitting diffusion plate body are respectively coated with an anti-escape surface glue layer. The finished product provides three protection measures for preventing the quantum dots from escaping, and the effect of preventing the quantum dots from being dissipated due to heating is achieved.

Description

[0001] The priority basis of the present invention is: application number 202010514395.2, application date 2020.06.08, patent title "quantum dot diffusion plate, manufacturing method and backlight module for preventing quantum dots from heat dissipation". technical field [0002] The invention relates to the technical field of diffusion plates of display backlight modules, in particular to a quantum dot diffusion plate for preventing quantum dots from being heated and dissipated, a manufacturing method and a backlight module. Background technique [0003] Diffusion plates are commonly used in backlight modules, and the specific application is the direct-lit backlight module using LED light sources. It mainly uses the principle of multi-angle light refraction to diffuse the light emitted by the light source. It can have a more uniform luminous performance. The early LED light sources were equipped with three-color lamp beads, but based on the chip manufacturing process and th...
