Backlight module and display device

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a back plate, a light-emitting component positioned on the back plate and a frame positioned at the periphery of the back plate, wherein the frame comprises a main body part and a wedge-shaped part which is positioned at one side, close to the light-emitting component, of the main body; the inclined surface of the wedge-shaped part faces to the light-outgoing surface of the light-emitting component, and an included angle formed between the inclined surface of the wedge-shaped part and the light-outgoing surface of the light-emitting component is an acute angle; the inclined surface of the wedge-shaped part is provided with a groove for embedding of the light-emitting component. The backlight module and the display device provided by the invention have the advantages that the frame design with the wedge-shaped part is mainly utilized, the outgoing of light of a backlight source at the edge in the design of a narrow-edge frame is improved, and the problem of disappearance of edge pixels in side looking is solved.

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] In the liquid crystal display device, the backlight module is one of the key components of the liquid crystal display device, which is mainly used to provide sufficient brightness and uniformly distributed light source so that the liquid crystal panel can display images normally. The main components of the backlight module include light-emitting elements, reflectors, light guide plates, optical films, frames, and backplanes. Wherein, the frame is used for connecting or positioning other components in the backlight module, and plays a certain supporting and fixing role. [0003] However, in the increasingly popular narrow bezel design (the width of the front frame (Module Bezel) is smaller than that of conventional products), the frame (Mold Frame, also known as the plastic frame) usually has to...
