Embodiment Construction

[0017] see figure 2 , is a three-dimensional exploded schematic view of the first embodiment of the liquid crystal display device of the present invention. The liquid crystal display device 2 includes a backlight module 20 and a liquid crystal panel 29 adjacent to the backlight module 20 . The backlight module 20 includes a frame 21 , a light guide plate 23 , a plurality of light sources 25 , a diffusion sheet 27 and a prism sheet 28 . The frame 21 is a plastic frame, which defines a receiving space (not shown). The light guide plate 23 , the diffusion sheet 27 , the prism sheet 28 and the liquid crystal panel 29 are sequentially stacked and accommodated in the accommodation space from bottom to top. The plurality of light sources 25 are disposed adjacent to the light guide plate 23 , all of which are light emitting diodes (Light Emitting Diode, LED).

[0018] The frame 21 includes a bottom plate 210, a first side wall 211, a second side wall 213 opposite to the first side...

Abstract

The invention relates to a backlight module and an LCD device adopting the backlight module. The backlight module comprises a frame and at least two optical elements, wherein, the frame includes a side frame which includes at least two containing grooves with an interval arrangement, and the two optical elements which include at least a lug respectively are contained in the frame, besides, the lugs are contained correspondingly in the two containing grooves. The assembly identification level of the backlight module and the LCD device adopting the backlight module of the invention is very high.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] Since the liquid crystal in the LCD panel does not emit light, in order to achieve the display effect, it is necessary to provide the LCD panel with a light source device, such as a backlight module, to realize the display function. [0003] see figure 1 , is a three-dimensional exploded schematic diagram of a backlight module in the prior art. The backlight module 1 includes a frame 11 , a light guide plate 14 , a plurality of light sources 15 and an optical film set 17 . The light guide plate 14 includes a light incident surface 144 and a light exit surface 145 adjacent to the light incident surface. The plurality of light sources 15 are disposed adjacent to the light incident surface 144 , and the light emitted by them enters the light guide plate 14 through the light incident surface 144 , and is transformed i...
