Panel display device, stereo display device and plasma display device

Abstract

The invention provides a panel display device, which comprises a backlight system and a display panel, wherein the backlight system comprises a light source, a light homogenizing mechanism and a back frame; the back frame bears the light source and the light homogenizing mechanism; the light homogenizing mechanism introduces light from the light source into the display panel; the back frame comprises main splicing pieces, auxiliary splicing pieces and an adjustable bracket; the strength of the back frame is improved by arranging reinforced structures on splicing parts of the main splicing pieces; and at least two optional fixing points are arranged between the bracket and the main splicing pieces or the auxiliary splicing pieces, so that the bracket is optionally arranged at different positions of the back frame. The invention also provides a stereo display device and a plasma display device. A back frame mold is simple in structure, so that the cost of the back frame mold can be reduced; and materials of the back frame are saved, so that the cost of the panel display device is reduced.

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
