Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, a backlight assembly of the present invention includes at least two groups of optical modules 2 arranged on the back plate 1, and each group of optical modules 2 includes a light bar 3, a light guide plate 4, and a reflection sheet arranged at the lower end of the light guide plate 4 5. The first base 6 carrying the light guide plate 4 and the reflector 5 of an adjacent group of optical modules 2, the light bar 3 is arranged on the side of the first base 6 opposite to the side of the light guide plate 4, on the first base 6 There is an inclined portion 61 extending obliquely toward the direction of the light guide plate 4. The upper end surface of the inclined portion 61 is an inclined surface, and the inclined surface is provided with a light for reflecting the light emitted by the light bar 3 of an adjacent ...

Abstract

The invention provides a backlight module. The backlight module comprises optical modules arranged on a back plate, the optical modules comprise lamp strips, light-guiding plates and reflector plates arranged at the lower ends of the light-guiding plates, and the two or more sets of optical modules are arranged. Each optical module set further comprises a first base for bearing the light-guiding plate and the reflector plate of the adjacent optical module set, the lamp strips are arranged on the faces, opposite to the lateral edges of the light-guiding plates, of the first bases, inclined portions are arranged on the first bases and extend to the light-guiding plates in an inclined mode, the upper end faces of the inclined portions are inclined faces, reflecting layers used for reflecting light emerged by the lamp strips of the adjacent optical module sets are arranged on the inclined faces, the optical modules are covered with optical membrane sets, and the reflecting faces of the reflecting layers face the optical membrane sets. The invention further provides a liquid crystal display panel. The liquid crystal display panel comprises a display panel body and further comprises the backlight module. Compared with the prior art, partition control over a backlight source is achieved; thickness is reduced, and the problem that brightness at spliced positions is low is solved either.

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...
