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

摘要

Provided is a flat-panel display device (20) comprising a backlight system (21) and a display screen (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 screen (22). The back frame (23) comprises main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283), secondary assembly components (235, 236), and support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377, 60) for fixing in place a circuit board (80). The assembly parts (2311, 2312, 2361, 2362) of the main assembly components (231, 232, 233, 234, 261, 262, 281, 282, 283) of the back frame (23) are provided with a reinforced structure enabling the overall strength of the back frame (23) to satisfy requirements. The support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377, 60) comprise a support bracket main body (61), a first hanging part (62), a first off-set part (63) and a first flexible flip part (64); said support brackets (2371, 2372, 2373, 2374, 2375, 2376, 2377, 60) resolve the difficulty of fixing in place the circuit board (80). 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 while economizing materials for the back frame (23), thus reducing the cost of the flat-panel display device (20).
