A direct type backlight module and display device

Abstract

The invention discloses a straight down type backlight module which comprises a reflector sheet, a diffusion plate, a plurality of light sources and a plurality of supports, wherein the plurality of light sources are located on the side, facing towards the diffusion plate, of the reflector sheet. Each support is installed on the reflector sheet, the top of each support abuts against the diffusion plate, and each support comprises a support body and a plurality of micro interface processing structures located on lateral faces of the support body, wherein each micro interface processing structure is provided with a micro interface facing towards a corresponding support body base seat, and the angle degree of an included angle between each micro interface and a bottom face of the corresponding support body seat and along the direction departing from the corresponding support main body is 0-90 degrees. The invention further discloses a display device provided with the straight down type backlight module. The straight down type backlight module can improve the density of light rays on a top area of each support, relieve support shadows formed on the diffusion plate in a light-on state, and improve the display quality of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a direct-lit backlight module and a display device. Background technique [0002] In the field of display technology, large-size display devices often use large-size direct-lit backlight modules in order to ensure the brightness of the display. The backlight module provides a light source. [0003] Such as Figure 1a As shown, the direct type backlight module generally includes a reflector 06 , a diffuser 07 , a plurality of light sources 05 located on the side of the reflector 06 facing the diffuser, and a bracket 10 supporting the diffuser 07 . The bracket 10 is used in the direct type backlight module to support the weight of the diffuser plate 07 and the display panel on the diffuser plate 07 . However, as the size of the direct-lit backlight module increases, the contact area between the top of the bracket 10 and the diffusion plate 07 must be increased to ensure the stab...

AI Technical Summary

Problems solved by technology

[0012] As the contact area between the top of the bracket 10 and the diffuser plate 07 increases, the greater the distance away from the top of the bracket 10 after the light is refracted, the more sparse the light at the contact position between the diffuser plate 07 and the top of the bracket 10, and then it diffuses when the light is on. The shadow of the bracket 10 formed on the board 07 is more obvious, which affects the display quality of the product
