Backlight module with narrow frame of liquid crystal display device

Abstract

The invention provides a backlight module with a narrow frame of a liquid crystal display device. The backlight module comprises the frame, a back plate, a connection piece and a rubber frame which is arranged on the back plate; the frame comprises a bottom plate opposite to a front panel; the front panel of the frame concaves inwards to form a first tapping hole with an inner thread; the bottom plate of the back plate is provided with a hole part corresponding to the tapping hole; the rubber frame is provided with a through hole corresponding to the hole part; the connection part passes through the through hole; and both ends are respectively in a fit connection with the first tapping hole on the front panel of the frame and the hole part on the bottom plate of the back plate so that the frame is locked with the back plate. According to the backlight module provided by the invention, space positions of the rubber frame and the back plate are saved; meanwhile, material is avoided be cut by the rubber frame in a large area to avoid convex hulls on the frame and the back plate, therefore, the structure intensity of the rubber frame is ensured, and the frame of the backlight module is easy to narrow.

Description

technical field [0001] The invention relates to the technical field of TFT-LCD liquid crystal display, in particular to a narrow frame backlight module of a liquid crystal display device. Background technique [0002] Due to the advantages of low power consumption and low radiation, liquid crystal display devices have been widely used in current display devices. With the continuous advancement of technology in the liquid crystal industry, the large size and thinness of liquid crystal display devices have increasingly become the mainstream demand of the market. Liquid crystal display devices generally include liquid crystal panels and backlight modules, and the structure of backlight modules is largely It determines the large size and thinness of the liquid crystal display device, so the narrow frame of the backlight module has become a trend. The backlight module generally includes a frame, a back plate connected with the frame, and a plastic frame and a guide on the back pl...

With the continuous advancement of technology in the liquid crystal industry, the large size and thinness of liquid crystal display devices have increasingly become the mainstream demand of the market. Liquid crystal display devices generally include liquid crystal panels and backlight modules, and the structure of backlight modules is largely It determines the large size and thinness of the liquid crystal display device, so the narrow frame of the backlight module has become a trend. The backlight module generally includes a frame, a back plate connected with the frame, and a plastic frame and a guide on the back plate. The light plate, and the optical film on the light guide plate, etc., the frame includes a front panel forming a display opening, and a side panel extending downward from one end of the front panel, and the liquid crystal panel is arranged on the backlight module corresponding to the display opening of the front panel. On the set, due to the narrow frame of the backlight module, the width and thickness of the front panel of the frame are narrow and thin, resulting in no space for placing nuts on the front panel of the frame, and the nuts cannot exceed the surface of the frame, so they cannot be placed on the front panel of the frame. screw lock

[0003] In order to solve the above-mentioned problems, the screw locking method of the narrow frame backlight module of the existing liquid crystal display device is to punch a screw countersunk hole on the side plate of the frame, and lock the screw with the back plate. The locking method needs to make a lot of convex hulls on the back panel to cooperate with the countersunk convex feature of the frame, which takes up a lot of space on the back panel, which is not conducive to other structures on the convex hull position of the back panel. At the same time, in order to avoid the position, The plastic frame must be hollowed out at the convex position of the back panel and the frame, which greatly weakens the structural strength of the entire plastic frame
