BACK FRAME OF FLAT-PANEL DISPLAY DEVICE, MANUFACTURING METHOD OF BACK FRAME, AND BACKLIGHT SYSTEM

摘要

A flat-panel display device (20), a stereoscopic display device (30) and a plasma display device (40) comprise a backlight system (21) and a display panel (22). The backlight system (21) comprises a light source (25), a light uniformizing mechanism (24) and a back frame (23). The back frame (23) bears the light source (25) and the light uniformizing mechanism (24). The light uniformizing mechanism (24) guides light from the light source (25) into the display panel (22). The back frame (23) comprises at least two main splicing pieces (261, 262, 281, 282, 231, 232) which are connected in a splicing manner. The at least two main splicing pieces (261, 262, 281, 282, 231, 232) are spliced by using a plurality of dispersed splicing points. The flat-panel display device (20), the stereoscopic display device (30) and the plasma display device (40) have a simple structure, the cost of a back frame mold can be reduced, and the material of the back frame (23) is saved, so that the cost is further reduced. Moreover, the strength of the splicing position of the back frame (23) is guaranteed while the stress is dispersed, which ensures the whole strength of the back frame (23) to meet the requirement.
