Liquid Crystal Display Module {LIQUID CRYSTAL DISPLAY MODULE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display module, and more particularly, to a liquid crystal display module capable of preventing damage to a lamp and improving display quality.

In general, liquid crystal display (Liquid Crystal Display) due to the characteristics of light weight, thin, low power consumption, etc., the application range is gradually increasing. In accordance with this trend, liquid crystal displays have been used for office automation equipment, audio / video equipment, and the like. On the other hand, the liquid crystal display device displays the desired image on the screen by adjusting the transmission amount of the light beam according to image signals applied to the plurality of control switches arranged in a matrix form.

A general liquid crystal display device is composed of a liquid crystal display module and a driving circuit portion for driving the liquid crystal display module.

The liquid crystal display module includes a liquid crystal panel in which liquid crystal cells are arranged in a matrix form between two glass substrates, and a back light unit for irradiating light to the liquid crystal panel. In addition, in the liquid crystal display module, optical sheets for vertically raising light traveling from the backlight unit toward the liquid crystal panel are arranged. The liquid crystal panel, the backlight unit and the optical sheet must be fastened in an integrated form to prevent light loss and must be protected from damage by external impact. To this end, a case for a liquid crystal display device formed to surround the backlight unit and the optical sheets including the edge of the liquid crystal panel is provided. Since the liquid crystal display module is not a self-luminous display device, a light source such as a backlight is required. There are two types of backlight of the liquid crystal display module, a direct type type and an edge type type.

In the edge type method, a fluorescent lamp is installed outside the light guide plate, and light from the fluorescent lamp is incident on the entire surface of the liquid crystal panel using a transparent light guide plate. The direct type method is a method of directly dimming the front surface of the liquid crystal panel by placing a light source on the rear surface of the liquid crystal panel. Thus, a plurality of light sources may be disposed to increase luminance and widen the light emitting surface as compared to the edge type method.
