Abstract

The invention discloses a backlight module and a display device, and belongs to the technical field of display and comprises a casing, a plurality of light sources and a light guide plate, the backlight module is a side-entry backlight module, the casing at least comprises a back plate and a side plate which are integrally formed, a flexible circuit board extending along a first direction is fixedly arranged on the surface of one side, close to the light guide plate, of the back plate, and the light sources are positioned on one side, away from the back plate; the backlight module further comprises a diffusion sheet and a brightening sheet. The brightening sheet and the light guide plate are at least partially overlapped along the direction vertical to the light emitting surface of the backlight module; a shading strip is attached to the surface of the side, close to the light guide plate, of the diffusion sheet. The display device comprises a liquid crystal display panel and the backlight module which are oppositely arranged. The manufacturing process is simple, the narrow frame of the backlight module can be achieved without changing the original manufacturing process of the backlight module, meanwhile, the firefly phenomenon can be avoided, and the display quality of the backlight module can be 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] In the existing display devices, the display panel is mainly divided into two mainstream technologies of liquid crystal display panel and organic self-luminous display panel. Among them, the liquid crystal display panel forms an electric field that can control the deflection of liquid crystal molecules by providing appropriate voltages to the pixel electrodes and common electrodes, and then controls the transmission of light to realize the display function of the display panel; the organic self-luminous display panel uses organic electroluminescent materials , when a current passes through the organic electroluminescent material, the luminescent material will emit light, thereby realizing the display function of the display panel. With the rapid development of display technology, liquid crys...
