Back frame and backlight system

Abstract

A back frame (23) for a flat-panel display device (20). The back frame (23) comprises main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283), secondary assembly components (235, 236), as well as support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377, 60) for fixing in place a circuit board (80). The main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283) are at least two in number, one end of at least one of the main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283) is provided with assembly parts (2311, 2312, 2361, 2362), and the secondary assembly parts (235, 236) assemble onto the main assembly parts (231,232,233,234,261,262,281,282,283). At least two main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283) assemble together by means of the corresponding assembly parts (2311, 2312, 2361, 2362); the assembly parts (2311, 2312, 2361, 2362) of at least one of the main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283) are provided with a reinforcing structure. The support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377, 60) comprise a support bracket main body (61), a first hanging part (62), a first off-set part (63) and a first flexible flip part (64). Also provided is a backlight system (21). The structural simplicity of the back frame (23) reduces the cost of the mold for the back frame and economizes on materials for the back frame (23), thus reducing the cost of the flat-panel display device (20).

Description

technical field [0001] The invention relates to the field of display technology, in particular to a back frame and a backlight system of a flat panel display device. Background technique [0002] In the prior art, a liquid crystal display device includes a front frame, a panel, and a backlight module, wherein the backlight module includes a back frame, a reflection sheet, a light guide plate, and a lamp group. [0003] Currently, there are various sizes of display panels on the market to meet people's different needs. For example, in the field of television, the size of LCD panels includes 31.5, 42, 46, 48 or 55 inches, and different back frame molds need to be set according to different sizes of LCD panels. [0004] See figure 1 , figure 1 It is a schematic diagram of the structure of the back frame of the liquid crystal display device in the prior art. like figure 1 As shown, the back frames 10 in the prior art all adopt an integral back frame, and the integral back f...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the back frames 10 in the prior art all adopt an integral back frame, and the integral back frame 10 is usually produced by metal stamping or plastic injection. The integral back frame 10 needs to consume too much material, and the material cost is high.

In addition, the large-sized back frame 10 needs to use relatively large stamping equipment, and the mold corresponding to the back frame 10 has a large size and complex structure, and the cost of the back frame mold is high.

Therefore, the cost of the back frame of the prior art is high
