Abstract

The invention is related to the backlight module, and the liquid crystal display device of using the backlight module. The backlight module includes a light guide plat with a light entering face, and a light source near to the light entering face. The light source includes a strip of supporter. At least a light emitting diode (LED) and a reflection element adjacent to the LED are setup on the strip of supporter. The backlight module is easy of assembling.

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 display is a non-self-illuminating display device, in order to achieve the display effect, it is necessary to provide a light source device for the liquid crystal display to realize the display function, such as a backlight module, whose function is to provide a backlight with sufficient brightness and uniform distribution to the liquid crystal display source. [0003] A backlight module of the prior art is shown in Figure 1, the backlight module 1 includes a metal backboard 11, a light source group 14, a light source reflector 13, a light guide plate 16 accommodated in the metal backplane 11 and A reflection sheet 15. The light guide plate 16 includes a light emitting surface 161 , a light incident surface 162 and a bottom surface 163 opposite to the light emitting surface 161 . The r...
