Backlight components and liquid crystal display modules

Abstract

A backlight assembly and a liquid crystal display panel comprising a display panel (9) and the backlight assembly. The backlight assembly comprises optical modules (2) disposed on a back plate (1); each optical module (2) comprises a light bar (3), a light guide plate (4), and a reflector plate (5) disposed at the lower end of the light guide plate (4); at least two sets of optical modules (2) are provided; each set of optical module (2) further comprises a first base (6) bearing the light guide plate (4) and the reflector plate (5) of an adjacent set of optical modules (2); the light bar (3) is disposed on the side of the first base (6) opposite to a side edge of the light guide plate (4); the first base (6) is provided with an inclined portion (61) obliquely extending towards the light guide plate (4); the upper end face of the inclined portion (61) is an inclined surface, a reflecting layer (62) used for reflecting light emitted by the light bars (2) of the adjacent set of optical modules (2) is provided on the inclined surface; each optical module (2) is covered with an optical film set (7); and the reflecting surface of the reflecting layer (62) faces toward the optical film set (7). Compared with the prior art, partition control of a backlight source is achieved, thickness is reduced, and the problem of low brightness at the splice is also resolved.

Description

technical field [0001] The invention relates to a liquid crystal panel module technology, in particular to a backlight assembly and a liquid crystal display module. Background technique [0002] The backlight of common liquid crystal display modules is mainly divided into two types: side-illuminated type and direct-lit type. The side-illuminated type backlight module has an advantage in thickness, which is conducive to the thin design of the product, but the brightness of the side away from the light source will be lower. It is lower than the side close to the light source, resulting in uneven brightness distribution; while the direct backlight is more conducive to the partition control of the display and obtains a better display image, but how to obtain a better display image while also realizing the traditional The advantage of the thickness of the side-lit backlight assembly has become a problem that needs to be solved urgently. Contents of the invention [0003] In or...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a backlight assembly and a liquid crystal display module, so that the side-type backlight can realize multi-zone control, and the problems of uneven thickness and brightness distribution can be reduced
