Flat-panel display device, stereoscopic display device and plasma display device

Abstract

The invention provides a flat-panel display device which comprises a backlight system and a display panel. The backlight system comprises a light source, a dodging mechanism and a back frame, wherein the back frame is used for bearing the light source and the dodging mechanism; the liquid equalizing mechanism is used for introducing light from the light source into the display panel; the back frame comprises at least two main splicing members which are spliced to form a main framework of the back frame; one of the at least two main splicing members is a main splicing member provided with a heating source; the main splicing member provided with the heating source has first heat-transmission capacity; other one or more main splicing members with no heating source in at least two main splicing members have second heat-transmission capacity; and the first heat-transmission capacity is greater than the second heat-transmission capacity. The invention also provides a stereoscopic display device and a plasma display device. According to the invention, a back frame die has a simple structure, so that the cost of the back frame die can be reduced; in addition, the material of the back frame is saved, so that the cost of the flat-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

In the cost of the backplane, the cost of raw materials accounts for the largest proportion. If the backplane is all made of aluminum, the cost will be too high and the structural strength will be poor; if all the backplanes are made of galvanized steel, the heat dissipation will not be good and the product performance will be reduced.
