Back frame and backlight system

Abstract

A back frame (23) of a flat-panel display device (20), a method for manufacturing the flat-panel display device (20), and a backlight system (21). The back frame (23) comprises at least two main assembly components, said at least two main assembly components connecting together in an assembling manner. The length of the at least two main assembly components is adjustable to form the main frame structure (27) of the back frame (23), of different sizes, the length of the two sides, of the main frame structure (27), parallel to each other being adjustable. By means of the described method, the structure of the back frame (23) mold is simple, the cost thereof is lowered, the material for the back frame (23) is conserved, and the production cost of the flat-panel display device (20) is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a back frame and a backlight system. 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. Such as 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 ...

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
