Abstract

The invention discloses a diffusion plate bracket, a direct type backlight module and a display device, and relates to the technical field of display equipment. The diffusion plate bracket, the direct type backlight module and the display device aim to solve the problem that after an existing diffusion plate bracket is installed on the direct type backlight module, light emitted by a light source of the direct type backlight module is easily blocked and thus a bracket shadow is formed on a diffusion plate. The diffusion plate bracket includes a base and a supporting part arranged above the base, the base is used for being fixed with a black plate of the direct type backlight module, the supporting part is used for supporting the diffusion plate of the direct type backlight module, the supporting part is of a transparent structure, a containing cavity is formed in the supporting part, luminescent materials are packaged in the containing cavity, and the luminescent materials can emit light under the trigger action of the light emitted by a light source of the direct type backlight module. The diffusion plate bracket is used for supporting the diffusion plate to prevent the diffusion plate from collapsing.

Description

technical field

[0001] The invention relates to the technical field of display equipment, in particular to a diffuser plate support, a direct-lit backlight module and a display device. Background technique

[0002] At present, backlight modules used in liquid crystal display devices include direct-type and side-type backlight modules. Compared with side-type backlight modules, direct-type backlight modules have better backlight color gamut, more uniform backlight brightness and Capable of dynamic backlighting.

[0003] example, figure 1 Shown is a direct type backlight module in the prior art, see figure 1 , the direct-type backlight module includes a diffusion plate 01 and a back plate 02 stacked up and down, and an LED (Light Emitting Diode, light-emitting diode) dot matrix light source 03 is arranged on the surface of the back plate close to the diffusion plate. There is a certain light mixing gap 04 between them, and the light emitted by the LED dot matrix light sourc...
