Panel display device and stereo display device

Abstract

A flat-panel display device (20) and a stereo display device (30). The flat-panel display device (20) comprises a backlight system (21) and a display panel (22), said backlight system (21) comprising a reflective panel (70) and a back frame (23) supporting the reflective panel (70). The back frame (23) comprises at least two main assembly components (261, 262), said at least two main assembly components (261, 262) assembling together to form the main frame structure (27) of the back frame (23). In addition, the base layer of the reflective panel (70) is provided with a metallic mesh (60) for preventing electromagnetic interference. By means of the described method, the back frame (23) of the backlight system (21) of the flat-panel display device (20) and stereo display device (30) is simple in structure and economizes on materials for said back frame (23), thus reducing the cost of same. In addition, the arrangement in the base of the reflective panel (70) of a metallic mesh (60) enables the flat-panel display device (20) and stereo display device (30) of the assembly-type back frame (23) easily to prevent electromagnetic interference, and also further reduces the production costs of the flat-panel display device (20) and stereo display device (30).

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flat panel display device and a stereoscopic 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 back fra...

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
