Abstract: The present invention provides a slim bezel backlight module of liquid crystal display device, which includes: a bezel, a back panel, a connection member, and a plastic frame arranged on the back panel. The bezel includes a front plate that forms a displaying opening and a side plate extending downward from an end of the front plate. The back panel includes a bottom board that is opposite to the front plate. The front plate of the bezel is recessed to form a first extruded threaded hole having internal threading. The bottom board of the back panel forms a bore corresponding to the first extruded threaded hole. The plastic frame forms a through hole corresponding to the bore. The connection member extends through the through hole and has two ends respectively mating and connecting the first extruded threaded hole of the front plate of the bezel and the bore of the bottom board of the back panel to thereby fix the bezel to the back panel. The present invention saves a great amount of space and sites on the plastic frame and the back panel and avoids removal of material in a large area of the plastic frame for not interfering with the bumps of the bezel and the bumps of the thereby guaranteeing the structural strength of the plastic frame and helping the sliming of the bezel for the backlight module.

Abstract translation: 本发明提供了一种液晶显示装置的薄型背光背光模块，其包括：背面板，后面板，连接构件和布置在后面板上的塑料框架。 边框包括形成显示开口的前板和从前板的一端向下延伸的侧板。 后面板包括与前板相对的底板。 挡板的前板被凹入以形成具有内螺纹的第一挤压螺纹孔。 后面板的底板形成对应于第一挤出螺纹孔的孔。 塑料框架形成与孔相对应的通孔。 连接构件延伸穿过通孔并且具有分别配合并连接边框的前板的第一挤出螺纹孔和后面板的底板的孔的两个端部，从而将边框固定到后面板。 本发明在塑料框架和后面板上节省了大量的空间和位置，并且避免了在塑料框架的大面积内移除材料，以不干扰边框和凸块的凸起，从而保证了结构 塑料框架的强度，并帮助背光模块的边框变薄。

Abstract: The present invention relates to a backlight module that enhances heat dissipation of LED light sources and a display device. The backlight module that enhances heat dissipation of LED light sources includes an LED light strip, a back panel, a mixed coating layer including two materials, and a thermal diode/triode. The LED light strip is arranged on the back panel. The mixed coating layer is interposed between the LED light strip and the back panel and contacts both for transfer of heat. The thermal diode/triode is connected to the mixed coating layer to control temperature of the mixed coating layer. In operation, through regulation of temperature, the thermal diode/triode makes vibration frequencies of the two materials of the mixed coating layer consistent with each other at a given temperature. The display device includes the above descried backlight module that enhances heat dissipation of LED light sources. The present invention realizes obstruction free transfer of heat from the LED light strip to the aluminum extrusion or the back panel, eliminating bottleneck of heat conduction path; reduces the temperature of the LED light strip, extending the overall lifespan of the LED light strip; and eliminates the use of thermal pad in the backlight module so as to facilitate designing narrow side frame of the backlight module.
