Backlight Module and LCD Device

Abstract

The invention provides a backlight module and an LCD device. The backlight module includes an LGP, point light source(s), and a backplane. The side wall of the backplane is provided with a pit extending to the outside of the backlight module relative to the light incident surface of the LGP, and the light sources are arranged on the pit. In the invention, because the position of the backlight module where the light sources are fixed is provided with the pit, the distance between the light source and the inner edge of the rubber frame is added due to pit, i.e. the A value is increased. Thus, the dark zones between every two LEDs of the light source can be effectively eliminated, and hotspot can be prevented from occurring in the active area of the LCD device. Meanwhile, after the A value is increased, corresponding A value can be selected to enable the frame of the LCD device to be narrowed, namely the A value is between the critical value that the hotspot cannot occur and the maximum A value obtained by the pit; thus, the frame of the LCD device becomes narrower, and the active area of the LCD device is increased.
