Problems solved by technology

However, the lampshade 125 formed by stamping can only be produced corresponding to the side-light type backlight module 12 of a single size due to the limitation of the size of the mold. make
Moreover, the process of stamping and forming is relatively complicated (such as blanking, bending, etc.), and the defective products in the production process are recycled and remanufactured, and the process is also relatively complicated (such as metal melting, casting and remanufacturing, etc.), which will cause side effects. The reduction of process efficiency and the improveme

Abstract

The invention discloses a liquid crystal display (LCD) device, comprising a LCDpanel and a side-light backlight module, wherein the side-light backlight module is connected with the LCD panel and is provided with a light guide plate (LGP), at least one luminescence component and an extrusion component; the luminescence component is arranged at one side of the light guide plate and arranged in a holding unit; the extrusion component is provided with the holding unit and a load bearing unit; and the load bearing unit is used for defining the distance between the light guide plate and the LCD panel.

Description

technical field [0001] The present invention relates to a display device and its backlight module, in particular to a liquid crystal display device and its side-light backlight module. Background technique [0002] Due to the development of display technology in recent years, traditional CRT display devices have been gradually replaced by liquid crystal display devices. Wherein, due to the characteristic that the liquid crystal cannot emit light by itself, the backlight module must be used as the backlight source in the liquid crystal display device. [0003] Please refer to figure 1 As shown, it is a partial cross-sectional view of a conventional liquid crystal display device 1 . The liquid crystal display device 1 includes a liquid crystal display panel 11 , an edge-lit backlight module 12 and a frame 13 . The edge-lit backlight module 12 has a frame 121 , a back panel 122 , a CCFL tube 123 , a light guide plate 124 , a lampshade 125 and an optical film set 126 . [00...
