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

摘要

A flat-panel display device (20), a stereo display device (30), and a plasma display device (40). The 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) supporting the light source (25) and the light-diffusion mechanism (24). The light-diffusion mechanism (24) conducts light from the light source (25) to the display panel (22). The back frame (23) comprises at least two main assembly components (291, 292, 293, 294), and the at least two main assembly components (291, 292, 293, 294) assemble together to form the main frame structure (27) of the back frame (23). The at least two main assembly components (291, 292, 293, 294) include main assembly components (293, 294) for installing a heat source (25). The main assembly components (293, 294) for installing the heat source (25) have a first heat conductivity. The rest of the one or more main assembly components (291, 292), of the at least two main assembly components (291, 292, 293, 294), not for installing the heat source (25) has a second heat conductivity. The first heat conductivity is greater than the second heat conductivity. The simple structure of the back frame mold reduces the cost thereof while economizing materials for the back frame (23), thus reducing the cost of the flat-panel display device (20).
