Abstract:
The present disclosure belongs to the field of liquid crystal displays (LCDs), and more particularly relates to a packing device of a backlight module including a fixing frame, a rotating shaft, and a clamping piece which can rotate around the rotating shaft. The rotating shaft is fixed to the fixing frame. The clamping piece includes an upper arm and a lower arm, and the upper arm and the lower arm are respectively used for clamping upper and lower surfaces of the backlight module. When an opening formed by surrounding the upper arm and the lower arm is upward, one edge of the backlight module can be put above the lower arm. Then, the backlight module is slowly put down, and the lower arm of the clamping piece rotates around the fixing shaft under stress. When the opening formed by surrounding the upper arm and the lower arm of the clamping piece is in a horizontal direction, the lower arm comes into contact with the lower surface of the backlight module to form a supporting state, and the upper arm of the clamping piece is pressed against the upper surface of the backlight module. Thus, the backlight module is completely fixed. The packing device of the backlight module of the present disclosure can be up and down stacked, and the stress of each layer of backlight module is uniform. Thus, a problem of affecting optical quality of the backlight module due to gravity accumulation is solved.

Further, the liquid crystal display device incorporated with such backlight module is also benefited.
Abstract:
The backlight module comprises a backplane and a light guide plate arranged in the backplane. The backlight module also comprises a limiting member for limiting the light guide plate. The limiting member comprises a horizontal limiting structure. The horizontal limiting structure abuts against an edge of the light guide plate and a side wall of the backplane. A limiting member is arranged between the edge of the light guide plate and the side wall of the backplane. One side of the limiting member abuts against the light guide plate, and the other side of the limiting member abuts against the side wall of the backplane. The limiting member is used for filling in a gap from the side wall of the backplane to the edge of the light guide plate. Thus, the horizontal limiting of the light guide plate by directly using the limiting member is achieved.
