Abstract

The invention discloses a diffusion plate support which is used for a directly downward type LED backlight module. The diffusion plate support comprises a base and a cone arranged on the base, the cone is made of a semi-transparent material, the surface of the cone is a frosted surface, the base is made of a white lighttight material, and a triangular pyramid mini-structure is arranged on the surface of the base. Meanwhile, the cone and the base are integrally formed. When the diffusion plate support is utilized, light emitted by an LED can partially penetrate through the semi-transparent cone of the support. In addition, due to the fact that the surface of the semi-transparent cone is of an atomization particle structure and has a diffusion function, so that shadow cannot be generated on the surface of a screen, and the problem of cross shadow produced by a traditional diffusion plate support can be solved. In addition, due to the fact that the surface of the base part is of a white triangular pyramid microstructure, high reflectivity is achieved, the problem that the surface of the screen of a liquid crystal panel also becomes a shadow area is solved, and a display effect is more uniform.

Description

technical field [0001] The invention relates to a diffuser plate support, in particular to a diffuser plate support for a liquid crystal panel backlight module. Background technique [0002] In recent years, with the development of liquid crystal technology, the size of liquid crystal modules has become larger and larger, and people have higher and higher requirements for LCD TV screen quality. Among the existing direct-type LED module backlight technology, direct-type backlight In order to ensure the optical effect, the light mixing distance is an important parameter, generally between 15mm and 40mm. Due to the influence of its own gravity, stress and other factors, the diffusion plate will bend toward the back plate, and the distance from the diffusion plate to the LEDs will be uneven, resulting in poor picture quality and poor taste. Therefore, in the direct-type LED module, the diffuser plate support is required to support the diffuser plate, so that the distance from t...
