Abstract

The invention relates to the technical field of display devices, and provides a backlight module and a display device. The backlight module comprises a back plate unit and a light source unit, the back plate unit comprises a back plate, the back plate is provided with a light mixing cavity, and the light mixing cavity is used for mixing light generated by the light source unit; the light source unit comprises a diffusion substrate, a transparent electrode layer and a light source, the diffusion substrate is arranged on the side, provided with the light mixing cavity, of the back plate, the transparent electrode layer is arranged on the surface of the diffusion substrate, the light source is arranged on the surface of the transparent electrode layer, and the light-emitting face of the lightsource faces the back plate to ensure that light generated by the light source can irradiate the light mixing cavity; the light is mixed by the light mixing cavity and then is emitted from the backlight module; the light source is attached to the surface of the transparent electrode layer, and the light emitting surface of the light source faces the back plate, so that light rays generated by thelight source can irradiate the back plate and reach the diffusion substrate after being reflected by the back plate, the overall thickness of the backlight module can be reduced, and the number of lamp beads in the light source can be reduced.

Description

Technical field [0001] Technical Field The present invention relates to a display device, and more particularly, to a backlight module and a display device. Background technique [0002] The liquid crystal display device (Liquid Crystal Display, abbreviated as LCD) is a common type of display device having a high market share. Wherein the backlight assembly is an integral part of the liquid crystal display device, a backlight liquid crystal display device. [0003] A liquid crystal television, for example, the current LCD TV backlight module structure is often used in a direct type backlight structure, are lightweight, and relatively low cost, and thus help reduce the overall weight of the liquid crystal television and manufacturing costs. When using the direct type backlight structure, in order to improve the uniformity of the backlight, the light mixing takes a long distance (Optical Distance, abbreviated as the OD), resulting in the direct type backlight module of a larger thi...
