Problems solved by technology

[0004] The prior patent (Application No.: 201710081687.X) discloses a quantum dot diffusion plate manufacturing process, a light guide plate process, and the prepared light guide plate. The light guide plate is currently widely used in the backlight and lighting industries, but due to its structure and Due to the limitations of optical characteristics, the light guide plate cannot be used in direct-lit backlight modules and some LED lamps. Therefore, manufacturing a diffuser plate with quantum dots is the key to solving the problem

Abstract

The invention provides a manufacturing process of a quantum dot diffusion plate, and the diffusion plate. According to the manufacturing process of the quantum dot diffusion plate, PMMA is prepared by adding a quantum dot diffusant into MMA. The diffusion plate comprises a plate body and a water oxygen barrier layer; the outer surface of the plate body is coated with the water oxygen barrier layer; quantum dots and light diffusion agents are dispersed in the plate body uniformly.

Description

technical field [0001] The invention relates to the field of backlighting, in particular to a manufacturing process of a quantum dot diffusion plate and a diffusion plate. Background technique [0002] The light diffusion plate usually uses chemical or physical means to make the physical phenomena of refraction, reflection and scattering occur when the light encounters two media with different refractive indices on the way. Inorganic or organic light diffusing agents are added to the base of the substrate, or the light is artificially adjusted through the array arrangement of the micro-feature structure on the surface of the substrate, so that the light can be refracted, reflected, and scattered in different directions, thereby changing the traveling route of the light and realizing the incident The light is fully scattered to produce the effect of optical diffusion, and the light diffusion plate is widely used in liquid crystal display, LED lighting and imaging display syst...
