Liquid crystal display device

Abstract

The LCD device includes one LCD panel, one back light unit set below the LCD panel, and one carrier bezel for assembling the LCD panel and the back light unit. The carrier bezel includes several alignment devices set in its upper inside for fixing the LCD panel inside the carrier bezel.

Description

technical field [0001] The present invention provides a liquid crystal display device (LCD device), especially a device comprising a plurality of liquid crystal display panels (LCD panel) can be horizontally fixed on a carrier frame (carrier bezel) The liquid crystal display device within the positioning device. Background technique [0002] Backlight module is one of the key components of LCD products, and has been widely used in digital cameras, digital personal assistants (PDAs), satellite navigation systems, computer monitors and flat-screen TVs. Generally speaking, the backlight module used for liquid crystal display products has a light source generator (light source generator) and a diffusing plate (diffusing plate), in order to provide a uniformly dispersed light to the display panel, and then control the light on the display panel pixel electrodes to form the appropriate image. Wherein, the backlight module can be divided into a direct illuminance backlight module...

AI Technical Summary

Problems solved by technology

However if figure 2 As shown, the above-mentioned liquid crystal display device 10 uses the positioning devices 30 located at the four corners of the carrying frame 16 to press downwards to fix the liquid crystal display panel 12 in the carrying frame 16 in a vertical direction. There must be a gap 32 between the display panel 12 and the supporting frame 16, so that the thickness of the liquid crystal display device 10 increases

In addition, because the first stress F1 generated by the positioning device 30 for vertically fixing the display panel 12 only acts on the four corners of the supporting frame 16 instead of acting on the display panel 12 in a multi-point and uniform manner, Therefore, the fixing effect for the display panel 12 is greatly reduced

After a long period of use, the components such as the light guide plate 18, the light source generator 20, the reflector 22, the diffusion plate 24, and the prism 26 of the backlight module 14 are prone to shifting (shifting), resulting in the liquid crystal display device 10. The display quality has dropped significantly, seriously affecting the competitiveness of products in the market
