Abstract

The present invention provides a flat panel display device, which includes a backlight system and a display panel. The backlight system includes a light source, a light homogenization mechanism, and a back frame. The back frame carries the light source and the light homogenization mechanism. The light homogenization mechanism guides light from the light source to a light incidence surface of the display panel. The back frame includes at least two primary assembling pieces. The at least two primary assembling pieces are joined to for a main frame structure of the back frame. The at least two primary assembling pieces includes a primary assembling piece that has a heat source arranged thereon. The primary assembling piece that has the heat source arranged thereon has a first heat transfer capability. The remaining one or more primary assembling pieces of the at least two primary assembling pieces that have no heat source arranged thereon have a second heat transfer capability. The first heat transfer capability is greater than the second heat transfer capability. The present invention also provides a stereoscopic display device and a plasma display device. The back frame mold of the present invention is of a simple structure and can reduce the expenditure of the back frame mold, and can also save the material used for back frame so as to lower down the cost of flat panel display device.
