Bottom case of LED (light-emitting diode) display screen module

The utility model discloses a bottom case of an LED (light-emitting diode) display screen module. The bottom case is characterized in that the bottom case is fixedly connected with one side of a lamp panel by virtue of copper cylinders and a terminal of each copper cylinder extends to be propped against and connected with the lamp panel. According to the utility model, the conventional bottom case of the LED display screen is improved, the technical problem that electromagnetic leakage is easily caused when the lamp panel is grounded is smartly solved, a good electromagnetic shielding effect is achieved on the front of the LED display screen, and the other end of each copper cylinder used for fixing the bottom case extends, so as to fix the lamp panel; and meanwhile, the lamp panel is grounded by virtue of the copper cylinders, and the bottom case of the LED (light-emitting diode) display screen module disclosed by the utility model has the advantages of simple structure and low implementation cost.
