Panel display device, stereo display device and plasma display device

Abstract

The invention provides a panel display device, comprising a backlight system and a display panel, wherein the backlight system includes a light source, a light uniforming mechanism and a back frame, wherein the light source and the light uniforming mechanism are loaded on the back frame; a light of the light source is guided to the display panel via the light uniforming mechanism; the back frame comprises a main joint piece, an auxiliary joint piece and an adjustable rack, wherein the joint part of the back frame is provided with a reinforcing structure so that the integral intensity of the back frame meets the requirement; different materials are used for different joint parts according to the actual needs of the back frame so as to reduce the material cost; besides, the back frame is provided with an adjustable rack which is selectively installed on different positions of the back frame so that the same rack can meet different mounting requirement. The invention also provides a stereo display device and a plasma display device. The back frame mould provided by the invention has simple structure, reduces the cost of the back frame mould, saves the material of the back frame and reduces the cost of the panel 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
