Embodiment

[0058] Such as Figure 1-Figure 3 As shown, the liquid crystal display module of this embodiment includes a backlight assembly and a liquid crystal panel 8 fitted on the backlight assembly.

[0059] The backlight assembly includes a middle frame 1, a back plate 2, a diffusion plate 3, a reflection sheet 4, a light guide unit 5, and an optical film 6. The middle frame 1 has a first support step 11 and a second support step 12 arranged in sequence from front to back. , the third support step 13 and the first support step 11 , and the middle frame 1 is also provided with an insertion slot 14 . The liquid crystal panel 8 is bonded on the first supporting step 11 through the foam glue 9 .

[0060] The backplane 2 includes a flat panel 21 and a plug-in flange 22. The flat panel 21 is provided with a plurality of light sources 10. The plug-in flange 22 is arranged around the flat panel 21. The plug-in flange 22 is plugged into the socket of the middle frame 1. Inside the slot 14 , ...

Abstract

The invention discloses a backlight assembly and a liquid crystal display module. The backlight assembly comprises a middle frame, a back plate, a diffusion plate, a reflector plate and a light guideunit; the middle frame is used for supporting a liquid crystal panel, the back plate is buckled on the rear side of the middle frame, a plurality of light sources are arranged on the back plate, the diffusion plate is in lap joint with the middle frame, and the diffusion plate is located between the liquid crystal panel and the back plate. The reflector plate is in lap joint with the middle frameand located between the diffusion plate and the back plate, the light guide unit is in lap joint with the middle frame and located between the reflector plate and the diffusion plate, and the light guide unit is used for guiding light emitted by the light source to the diffusion plate. According to the backlight assembly, incident light of the edge of the diffusion plate is increased, and therefore the problem that when a liquid crystal display panel with the small BM width value is adopted, uneven brightness such as bright frames and dark frames can occur on the edge of the whole liquid crystal display module is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display equipment, in particular to a backlight assembly and a liquid crystal display module. Background technique [0002] Liquid crystal display modules are composed of liquid crystal panels and backlight components. According to the location of the light source, current liquid crystal modules are mainly divided into two types: direct-type and side-type. Due to consumers' extreme demand for product appearance, the frame of LCD TVs is getting narrower and narrower. , the thickness of the product is getting thinner and thinner. In order to meet the needs of the product frame, the BM area (the black area around the visible area) on the four sides of the LCD panel is also getting smaller and smaller. The width of the previous BM area is equal to 7.9MM. The width is equal to 5.9 mm, and now the width of the BM zone is equal to 0.99 mm. At present, the minimum width of the BM area can reach 0....
