Abstract

The invention discloses a backlight module and a liquid crystal display. The backlight module comprises an outer frame, a light source, a light guide plate, a glue frame and a plurality of buffer structures. The light source is arranged at one side in the outer frame; the light guide plate is arranged in the outer frame, positioned aside the light source and provided with a plurality of lugs, wherein the lugs are positioned at the two opposite sides of the light guide plate. The glue frame is arranged in the outer frame and positioned between the light guide plate and the light source, wherein the glue frame is provided with a plurality of recessed openings at a place corresponding to the lugs, and the recessed openings are suitable for bearing the lugs. In addition, the buffer structures are arranged on a bearing surface of the recessed openings of the glue frame. By the arrangement of the buffer structures, the backlight module has the preferential shock resistance effect.

Description

technical field [0001] The invention relates to a display, and in particular to a liquid crystal display with good impact test yield and a backlight module thereof. Background technique [0002] Whether it is a cathode ray tube display device or a liquid crystal display device, the backlight module needs to provide light to display images with sufficient brightness. Backlight modules can be classified into side-illuminated backlight modules and direct-lit backlight modules according to the location of the light source. [0003] Figure 1A is a cross-sectional view of a known side-illuminated backlight module, and Figure 1B for Figure 1A The top partial enlarged view of the light guide plate and the frame of the backlight module. like Figure 1A and Figure 1B As shown, in the side-illuminated backlight module 100 , a light guide plate 120 is usually provided beside the light source 110 to correct the light transmission direction of the light source 110 . In order to fa...
