FLAT-PANEL DISPLAY DEVICE, STEREO DISPLAY DEVICE AND PLASMA DISPLAY DEVICE

摘要

A flat-panel display device (20) comprises a backlight system (21) and a display panel (22). The backlight system (21) comprises a light source (25), a light-diffusion mechanism (24), and a back frame (23). The back frame (23) supports the light source (25) and the light-diffusion mechanism (24), said light-diffusion mechanism (24) conducting light from the light source (25) to the display panel (22). The back frame (23) comprises main assembly components (291, 292, 293, 294) and secondary assembly components (295, 296). The number of the main assembly components (291, 292, 293, 294) is at least two. At least two main assembly components (291, 292, 293, 294) assemble and form the main frame structure (27) of the back frame (23). The secondary assembly components (295, 296) are disposed inside said main frame structure (27) and are connected to the main frame structure (27). A portion of the main assembly components (291, 292, 293, 294) and of the secondary assembly components (295, 296) features a first density and a first strength, and another portion thereof features a second density and a second strength. The first density is greater than the second density and the first strength is greater than the second strength. Also provided are a stereo display device (30) and a plasma display device (40). The simple structure of the back frame (23) reduces the cost of the back frame mold and economizes on materials for the back frame (23), thus reducing the cost of the flat-panel display device (20).
