Abstract

The invention belongs to the technical field of display devices, and provides a back plate, a backlight module and a display device.The edge of the inner surface of the back plate is provided with a plurality of inner hole bosses, the edge of the back plate is provided with a sunken pit, and the sunken pit is sunken from one side of the inner surface of the back plate to one side of the outer surface of the back plate and extends by a circle in the circumferential direction of the back plate; the inner hole bosses are contained in the sinking pits, and the height of the inner hole bosses is smaller than or equal to the depth of the sinking pits. The backlight module comprises a light source, a diffusion sheet and a back plate. The display device comprises a display panel and a backlight module. According to the backboard, the inner hole boss is contained in the sinking pit, interference of the inner hole boss on the diffusion sheet is avoided, the width of the sinking pit provides enough machining allowance for the diffusion sheet, and therefore the diffusion sheet shrinks in a low-temperature environment, and the edge of the diffusion sheet cannot be exposed out of the inner side of the middle frame; the technical problem of light leakage caused by cold shrinkage of a diffusion sheet of an existing oversized liquid crystal display television is effectively solved, and the light leakage phenomenon can be avoided.

Description

technical field [0001] The present application belongs to the technical field of display devices, and more specifically relates to a backplane, a backlight module and a display device. Background technique [0002] In the market, a display device with a screen size exceeding 100 inches is generally referred to as a super display device. Among them, a super large-size LCD TV is sought after by many consumers because of its large format and realistic display effect. A super-large LCD TV generally includes a display panel and a backlight module. The backlight module provides illumination for the display panel, and the display panel displays images. [0003] The backlight module of an ultra-large LCD TV includes a backplane, a light source and a diffusion sheet. The light source and the diffusion sheet are arranged on the backplane, and the diffusion sheet is used to diffuse the light emitted by the light source to the display panel. Fix the installation with screws and the midd...
