Flat panel display device, stereo display device and plasma display device

Abstract

A flat-panel display device (20) comprises a backlight system (21) and a display panel (22). The backlight system (21) comprises a light source (25), a light-diffusion mechanism (24), and a back frame (512). The back frame (512) supports the light source (25) and the light-diffusion mechanism (24), and also comprises at least a first and a second main assembly components (231, 232), one end of the first main assembly component (231) being provided with at least two assembly parts (2311, 2312), each of the assembly parts (2311, 2312) structured so as to match one end of the corresponding second main assembly component (232); the first main assembly component (231) is connected by means of the assembly parts thereof (2311, 2312) to one end of the corresponding second main assembly component (232). The main assembly component is disposed with a standing part, the standing part serving to match the back frame (512) to the middle frame (511) and the front frame (510) of the flat-panel display device (20). Also provided are a stereo display device (30) and a plasma display device (40). The flat-panel display device (20), the stereo display device (30), and the plasma display device (40) use a fixing component (515) to fasten the back frame (512), and the middle frame (511) and the front frame (510) of the display device, thereby further stabilizing the overall framework of the display device.

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

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

[0005] In the prior art, the front frame, the middle frame and the back frame of the flat panel display device are scattered and assembled piece by piece, and are not uniformly fixed, which causes the overall frame of the flat panel display device to be relatively loose.
