The rear cover 30 is arranged on the rear side of the display lamp panel 10 and is connected with the display lamp panel 10. The conductive connecting piece 40 is arranged on the rear cover 30 and is used for mounting the LED display module on a cabinet frame 50 and / or a power supply box 70. The conductive connecting piece 40 is exposed forwardly from the rear cover 30 and is in conductive cooperation with the grounding structure 20.

[0038] According to the technical scheme of the present embodiment, the rear cover 30 is arranged on the rear side of the display lamp panel 10 and protects various devices on the rear side of the display lamp panel 10. The grounding structure 20 is arranged on the rear side of the display lamp panel 10. One end of the grounding structure 20 is in conductive connection with the display lamp panel 10, and the other end is in conductive connection with the conductive connecting piece 40 arranged on the rear cover 30. The LED display module is mounted on the cabinet frame 50 and / or the power supply box 70 through the conductive connecting piece 40. Thus, the display lamp panel 10 is in conductive connection with the cabinet frame 50 and / or the power supply box 70 through the grounding structure 20 and the conductive connecting piece 40 in sequence. Thus, the grounding of the LED display module is realized. The grounding structure 20 is arranged between the display lamp panel 10 and the conductive connecting piece 40, i.e., the grounding structure 20 is completely arranged inside the LED display module. Thus, the grounding structure 20 will not be bumped or dropped during the separate transportation of the LED display module. Thus, the technical scheme of the present embodiment can effectively solve the problem that the LED display module provided with the elastic grounding piece in the related art is difficult to be transported separately.

[0039] As shown in Figure 4 and Figure 5 The display lamp panel 10 is provided with a plug-in structure 11, the rear cover 30 is provided with a avoiding hole through which the plug-in structure 11 is arranged, and the conductive connecting piece 40 is arranged close to the avoiding hole.

For the LED display device arranged outdoors for use, the sealing performance of the plug-in positions of the display lamp panel 10 and the power supply box 70 needs to be ensured. The conductive connecting piece 40 is arranged close to the avoiding hole to press the sealing ring between the display lamp panel 10 and the power supply box 70.

One LED display box includes a plurality of LED display modules arranged in an array. The LED display modules located at different positions correspond to different positions of the power box 70, that is, the LED display modules located at different positions are plugged and conducted with the power box 70 at different positions. By arranging the first plug-in piece 111 and the second plug-in piece 112 on the display lamp panel 10, one kind of LED display module can be installed at different positions, and the installer can select to plug and conduct with the power box 70 through the first plug-in piece 111 or the second plug-in piece 112, without the need to arrange multiple LED display modules, thereby saving the processing and manufacturing cost of the LED display module.

[0042] Specifically, the LED display module further includes a sealing ring arranged on the outer periphery of the first plug-in piece 111 and the second plug-in piece 112.

When the first perforation is not covered with the cover plate 60, the LED display module is connected with the power box 70 through the second grounding part 22 and the second conductive connecting column 42. That is, whether the first plug-in part 111 is used for plug-in connection with the power box 70 or not, at least one grounding part can realize the plug-in connection between the LED display module and the box frame 50 or the power box 70, thereby ensuring the grounding effect of the LED display module.

[0047] When the second through hole is covered with the cover plate 60, the sealing rings at the second through hole abut against the rear cover 30 and the cover plate 60 respectively to seal the second plug-in piece 112. The rear cover 30 and the cover plate 60 are connected through the four fourth conductive connecting columns 44 at the four corner positions of the second through hole, which can ensure the clamping effect of the sealing rings. The LED display module is installed on the box frame 50 through the two third conductive connecting columns 43 at the two ends of the second through hole. When the second through hole is not covered with the cover plate 60, the sealing rings at the second through hole abut against the rear cover 30 and the power box 70 respectively to seal the second plug-in piece 112. The rear cover 30 and the power box 70 are connected through the four fourth conductive connecting columns 44 at the four corner positions of the second through hole, which can ensure the clamping effect of the sealing rings. When the second through hole is covered with the cover plate 60, the LED display module is conductively connected with the box frame 50 through the third grounding piece 23 and the third conductive connecting column 43. When the second through hole is not covered with the cover plate 60, the LED display module is conductively connected with the power box 70 through the fourth grounding piece 24 and the fourth conductive connecting column 44. That is, whether the second plug-in piece 112 is used for plug-in conductive connection with the power box 70 or not, at least one grounding piece can realize the conductive connection between the LED display module and the box frame 50 or the power box 70, thereby ensuring the grounding effect of the LED display module.
