Embodiment 1

[0031] like figure 1 As shown, this embodiment provides a backlight module, which includes an iron frame 1 , a reflection sheet 2 , a light guide plate 3 , a diffusion sheet 4 , a prism sheet 5 , a through hole 6 and a support member 7 .

[0032] The reflector 2, the light guide plate 3, the diffusion sheet 4 and the prism sheet 5 are sequentially arranged on the upper surface of the iron frame 1. When a backlight is from one side of the iron frame 1, the backlight is a side-emitting LED, which is used for the entire backlight. The module provides a backlight, and the light guide plate 3 is used to effectively distribute the light emitted by the backlight in the window area of ​​the backlight to form a surface light source.

[0033] The through hole 6 runs through the iron frame 1 , the reflection sheet 2 , the light guide plate 3 , the diffusion sheet 4 and the prism sheet 5 sequentially. The reflective sheet 2 is used for the reuse of light from the light guide plate 3, the...

Embodiment 2

[0047] like image 3 As shown, this embodiment provides a backlight module including an iron frame 1 , a reflection sheet 2 , a light guide plate 3 , a diffusion sheet 4 , a prism sheet 5 , a through hole 6 and a support member 7 .

[0048] The reflective sheet 2, the light guide plate 3, the diffuser sheet 4 and the prism sheet 5 are sequentially arranged on the upper surface of the iron frame 1. When a backlight source is from one side of the iron frame 1, the backlight source is a side-emitting LED, which is used for the entire backlight. The module provides a backlight source, and the light guide plate 3 is used for effectively distributing the light emitted by the backlight source in the backlight window area to form a surface light source.

[0049] The through hole 6 penetrates the iron frame 1 , the reflection sheet 2 , the light guide plate 3 , the diffuser sheet 4 and the prism sheet 5 in sequence. The reflective sheet 2 is used for reusing the light from the light g...

Abstract

The invention provides a backlight module and a display device. The backlight module comprises an iron frame, a light guide plate, a through hole and a supporting part. The light guide plate is set above the iron frame, the through hole penetrates through the iron frame and the light guide plate, and the supporting part is arranged at the through hole and is connected to the iron frame. The invention has the technical effects that the backlight module and the display device are provided, by adding the supporting part and the iron frame and fixing the supporting part in a dispensing mode or fixing the supporting part through a double faced adhesive tape, the through hole of the backlight module is light-proof, and the light leakage prevention effect is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] With the development of display technology, full-screen technology has emerged, and this type of technology is widely used in liquid crystal display modules. In small and medium-sized LCD modules, such as mobile phones, tablets, and notebooks, holes are opened in the LCD modules to install cameras, microphones, etc., so correspondingly, it is necessary to dig holes in the corresponding effective display area when designing the LCD module. . [0003] At present, the scheme of digging holes in the effective display area of ​​the liquid crystal display module usually includes digging the liquid crystal panel and the backlight module at the same time to form through holes, or only digging holes on the backlight module to form through holes. Both solutions will cause the liquid crystal display module to have no ...
