The heat dissipation frame 600 is arranged directly below the heat dissipation fin 500 , and the inner wall of the heat dissipation frame 600 is fixedly connected with a heat dissipation unit 601 .

[0034] By rotating the pressure strip 300, the pressure strip 300 can be abutted against the edge of the backlight panel 200, so that the backlight panel 200 can be fixed inside the mounting frame 100. At the same time, the clamping rod 400 is inserted into the side wall of the mounting frame 100 and clamped with the pressure strip 300, thereby completing the fixed installation of the backlight panel 200.

[0035] The heat dissipation frame 600 is arranged at the bottom of the mounting frame 100 and cooperates with the heat dissipation fins 500 to enhance the heat dissipation effect of the backlight panel 200 and greatly reduce the failure rate of the device during use.
