Flat display device, stereo display device and plasma display device

Abstract

The invention provides a flat display device, which comprises a backlight system and a display panel, wherein the backlight system comprises a light source, a light averaging mechanism and a back frame; the back frame carries the light source and the light averaging mechanism; the light averaging mechanism leads a light ray from the light source into the display panel; the back frame comprises at least two main splicing pieces which are connected with each other in a splicing manner; the lengths of the at least two main splicing pieces are adjustable so as to form main frameworks, which have different sizes, of the back frame; and the lengths of two parallel edges of the main framework are adjusted. The invention also provides a stereo display device and a plasma display device. By the mode, a die of the back frame has a simple structure, so the cost of the die of the back frame is reduced; furthermore, the material of the back frame is reduced, so the production cost 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
