Liquid crystal display module and liquid crystal splicing screen

Abstract

The present invention discloses a liquid crystal display module and a liquid crystal splicing screen. The liquid crystal display module comprises a liquid crystal panel, a middle frame, a back plate,a first reflector plate, a second reflector plate, a light guide unit and a diffusion plate, the middle frame is used for supporting the liquid crystal panel, the back plate is buckled on the rear side of the middle frame and connected with the middle frame through a connecting piece, and a light source is arranged on the back plate. The first reflector plate is arranged on the back plate, the light source can penetrate through the first reflector plate and the second reflector plate to be in lap joint with the middle frame, one end of the second reflector plate abuts against the first reflector plate, the light guide unit abuts against the first reflector plate, the diffusion plate is clamped between the light guide unit and the liquid crystal panel, and the light guide unit can guide light of the light source to the diffusion plate. According to the liquid crystal display module, the visual problem that the edge of the BM area of the liquid crystal panel is uneven in brightness whenthe width of the BM area is small can be well solved, the assembling and reworking difficulty of the liquid crystal panel can be lowered, and the assembling cost of the liquid crystal display module is reduced.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a liquid crystal display module and a liquid crystal splicing screen. Background technique [0002] LCD splicing screen is widely used in the field of high-definition large-screen display because of its clear picture quality, free splicing and disassembly like building blocks, and stable performance. At present, the biggest problem restricting the development of LCD splicing screens is that the seams between multiple LCD modules are too obvious, which will seriously affect the visual effect of the entire LCD splicing screen. [0003] An important parameter that determines the size of the seam between the liquid crystal display modules is the width of the BM area (the black area around the visible area) on the four sides of the liquid crystal glass panel. With the development of technology, the four sides of the liquid crystal glass panel are getting smaller and smaller, from the p...
