Backlight module and display device

Abstract

The invention discloses a backlight module and a display device. The backlight module includes: a back plate including a bottom plate, side plates arranged around the bottom plate, and a bent portionformed by bending the side plates, wherein the bottom plate, the side plates and the bent portion form a mounting space, the side of the bent portion opposite to the bottom plate is provided with a limiting step, and the bent portion includes upper and lower step faces connected to the limiting step; a reflector that is received in the mounting space and arranged on the bottom plate; a light guideplate received in the mounting space and arranged on the side of the reflector opposite to the bottom plate; a membrane received in the mounting space and arranged on the side of the light guide plate opposite to the reflector; and a display panel covering an opening of the mounting space and connected to the lower step face. The backlight module is simple to assemble and low in cost and has variable appearance.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a backlight module and a display device using the backlight module. Background technique [0002] At present, the module structure of the existing liquid crystal display device is summarized into two types. The first structure is (from the outside to the inside) including the front frame, the plastic frame, the film, the light guide plate, the reflection sheet, and the back plate, and the light guide plate The reflector and the reflector are installed on the back plate, the plastic frame is installed on the periphery of the back plate and connected with the light guide plate, the film and the screen are installed on the plastic frame, and the front frame is sleeved on the plastic frame and the periphery of the screen, resulting in many structural parts of the module structure. Module assembly is complex and costly; [0003] The second structure is (from outside to inside...

[0002] At present, the module structure of the existing liquid crystal display device is summarized into two types. The first structure is (from the outside to the inside) including the front frame, the plastic frame, the film, the light guide plate, the reflection sheet, and the back plate, and the light guide plate The reflector and the reflector are installed on the back plate, the plastic frame is installed on the periphery of the back plate and connected with the light guide plate, the film and the screen are installed on the plastic frame, and the front frame is sleeved on the plastic frame and the periphery of the screen, resulting in many structural parts of the module structure. Module assembly is complex and costly;

[0003] The second structure is (from outside to inside) including the middle frame, film, light guide plate, reflector, and back plate. The middle frame is installed on the periphery of the back plate, and the reflector, light guide plate, and film are installed on the back in order. On the board, the screen is installed on the middle frame, the module assembly is complicated, and there are no decorative parts, and the appearance is monotonous
