Problems solved by technology

However, since there is a distance between the side wall of the backplane and the light guide plate, and its own thickness is relatively large, a long double-sided adhesive is required to fix the backplane, the light guide plate and the optical film, increasing the non-visible area. The overall width of the border

Abstract

The invention provides a backlight module. The backlight module comprises a back plate, a light guide plate and optical films, wherein the back plate comprises a bottom plate and a side plate arranged on the bottom plate; a concave part is concavely arranged on the part, facing the surface of the bottom plate, of the side plate; the light guide plate and the optical films are arranged in the back plate; the side plate is arranged around the peripheries of the light guide plate and the optical films; a non-incident-light end of the light guide plate is inserted into the concave part; the optical films are overlapped on the light guide plate. The invention further provides a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a display device. Background technique [0002] At present, liquid crystal display devices have been widely used in various electronic products as display components of electronic equipment. With the development of thinner and lighter electronic products, the frame of electronic equipment is designed to be narrower and narrower. The backlight module is an important part of the liquid crystal display device, and the frame of the backlight module is bound to become narrower and narrower. [0003] The backlight modules in the prior art all include a plastic frame, the light guide plate is surrounded by the plastic frame, and the optical film is fixed on the light guide plate, the plastic frame and the back plate by light-shielding tape. It can be seen that the backplane, as a carrier for the light guide plate and the optical film, is an importa...
