In the relevant prior art, the display module includes a box and a display panel, the LED lamp beads are arranged on the front of the display panel, and the corresponding control components are arranged on the back of the display panel, or arranged in the box, and the box is installed on the back of the display panel to cover the relevant control parts and achieve a certain waterproof performance. In order to facilitate disassembly and maintenance, it is necessary to weld copper columns on the back of the display panel, set threaded holes on the copper columns, and set screws for connecting the threaded holes on the box. When the number of disassembly times is large, the copper columns will loosen and fall off, resulting in the need to replace the display module.

[0031] To this end, the utility model provides a display module, which is convenient for maintenance and repair and can avoid the problem of loose copper columns.

[0032] Reference Figures 1 to 6 As shown, a display module of an embodiment of the utility model includes an LED light board 100, a bottom shell 200 and a cover plate 300, wherein a plurality of threaded mounting holes 101 are provided on the back of the LED light board 100, and it should be noted that the threaded mounting holes 101 are directly formed on the LED light board 100. LED lamp beads are arranged on the front of the LED light board 100. The bottom shell 200 is provided with a plurality of mounting holes 205, and the mounting holes 205 are aligned with the threaded mounting holes 101, and the bottom shell 200 is provided with screws threadedly connected to the threaded mounting holes 101 in the mounting holes 205, so as to be fixedly installed on the back of the LED light board 100. At the same time, a plurality of inspection windows 203 are opened on the bottom shell 200. The inspection window 203 allows the bottom shell 200 to reveal the corresponding area when it is installed on the back of the LED light board 100.
