Panel display device, stereo display device and plasma display device

Abstract

Provided is a flat-panel display device (20) comprising a backlight system (21) and a display screen (22); the backlight system (21) comprising a light source (25), a light-diffusion mechanism (24) and a back frame (23). The back frame (23) supports the light source (25) and the light-diffusion mechanism (24), said light-diffusion mechanism (24) conducting light from the light source (25) to the display screen (22). The back frame (23) comprises main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283), secondary assembly components (235, 236) and adjustable support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377). By means of the assembly parts (2311, 2312, 2361, 2362) of the main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283), the back frame (23) is provided with a reinforced structure that enhances the strength thereof. At least two fixation points are provided for the support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377) relative to the main assembly components (231, 232, 233, 283, 262, 281, 282, 283) or secondary assembly components (235, 236) so that said support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377) can be arranged at different and optional positions on the back frame. Also provided are a stereo display device (30) and a plasma display device (40). The simple structure of the provided back frame module reduces the cost thereof while economizing 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 flat panel display device, a stereoscopic display device and a plasma 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...

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
