Abstract

The embodiments of the invention disclose a diffusion plate, a preparation method thereof and a backlight module. The diffusion plate includes a first diffusion layer and a second diffusion layer. Thefirst diffusion layer includes a first surface away from one side of the second diffusion layer and a second surface close to one side of the second diffusion layer. Multiple first microstructures are formed on the first surface. A second microstructure is formed on the second surface. The second diffusion layer includes a third surface close to one side of the first diffusion layer and a fourthsurface away from one side of the first diffusion layer. A third microstructure is formed on the third surface. Multiple fourth microstructures are formed on the fourth surface. On the diffusion plateprovided by the embodiments of the invention, the second microstructure and the multiple first microstructures are respectively formed on the second surface and the first surface of the first diffusion layer, the third microstructure and the multiple fourth microstructures are respectively formed on the third surface and the fourth surface of the second diffusion layer, and so the diffusion plateis simple in structure, can optimize a light source incident on the diffusion plate, and can improve the light utilization rate.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of semiconductors, and in particular to a diffusion plate, a manufacturing method, and a backlight module. Background technique [0002] With the development of the flat-panel TV industry, the backlight module, which is an important part of the TV, is constantly changing in terms of optical indicators, optical taste and cost composition in order to adapt to different market requirements. [0003] In the existing direct-type backlight module, the light emitted by the light source passes through the light guide plate and the reflector, and the light is incident into the lower diffusion plate along a certain opening angle, and the lower diffusion plate diffuses and atomizes the incident light for the first time. The light atomized by the lower diffusion plate enters the prism sheet, and the prism sheet regularly refracts and reflects the incident light, and then the incident light enters t...
