Abstract

The invention discloses a backlight module and a display device, and belongs to the technical field of display. The backlight module comprises a shell, a plurality of light sources, a light guide plate and a diffusion sheet assembly; a flexible circuit board extending in the first direction is fixedly arranged on the surface of the side, close to the light guide plate, of the back plate, and the light sources are located on the side, away from the back plate, of the flexible circuit board. The diffusion sheet assembly comprises a diffusion sheet, an auxiliary strip and a supporting part, one opposite section of area of the auxiliary strip in the second direction is attached to the diffusion sheet, the other section of area is attached to the supporting part, and the supporting part is supported between the auxiliary strip and the back plate. The display device comprises a liquid crystal display panel and any backlight module which are oppositely arranged. According to the backlight module, a narrow frame can be achieved, the structural part is formed by attaching the auxiliary strips of the supporting parts and used for providing supporting lap joint for the shading adhesive tape,lap joint attachment of the shading adhesive tape can be guaranteed, the light leakage problem of the module can be better solved, the assembling process difficulty is lowered, and the stability of the whole backlight module can be better improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a backlight module and a display device. Background technique [0002] With the rapid development of display technology, liquid crystal display devices (such as liquid crystal TV, liquid crystal display, liquid crystal display, etc.) The application in production and life is more and more extensive. However, the liquid crystal display device is a passive display device, which cannot emit light by itself, and needs to modulate external light to achieve the purpose of display. Therefore, the position of the backlight source in the liquid crystal display device is particularly important. The backlight module is one of the key components of the liquid crystal display device. Its main function is to provide a uniform and high-brightness illuminant for the liquid crystal panel. The basic principle is to convert the commonly used point or line light into high-brightn...
