Back frame and backlight system

Abstract

A back frame for a flat-panel display device. The back frame comprises main assembly components (301, 302, 303, 304), secondary assembly components (305, 306) and an adjustable support bracket (307). The main assembly components (301, 302, 303, 304) are at least two in number, the at least two main assembly components (301, 302, 303, 304) assemble together to form the main frame structure of the back frame, and the secondary assembly components (305, 306) assemble onto the main frame structure. Different materials may be used for the variously positioned main assembly components (301, 302, 303, 304) of the main frame structure according to actual utilizations. The back frame is also provided with a support bracket (307) fixed to the main assembly components (301, 302, 303, 304) or the secondary assembly components (305, 306). At least two fixation points (3071, 3072) are provided for the support bracket (307) relative to the main assembly components (301, 302, 303, 304) or the secondary assembly components (305, 306) so that the support bracket (307) can be arranged at different and optional positions on the back frame. Also provided is a backlight system. The structural simplicity of the back frame and the backlight system reduces the cost of the mold for the back frame while economizing on materials therefor, thus reducing the cost of the flat-panel display device and satisfying different requirements of installation.

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. Such as figure 1 As shown, the back frames 10 in the prior art all adopt an integral back frame, and the integral bac...

Problems solved by technology

In the cost of the backplane, the cost of raw materials accounts for the largest proportion. If the backplane is all made of aluminum, the cost will be too high and the structural strength will be poor; if all the backplanes are made of galvanized steel, the heat dissipation will not be good and the product performance will be reduced.
