A plurality of display modules 110 may be provided, and the plurality of display modules 110 are all fixed on the box frame 120 . In order to facilitate the display control of the display module 110, the display module 110 may be distributed in an array. For example, an even-numbered display module 110 is usually configured in a standard-sized box, so that the display modules 110 are arranged in a rectangle or a square, so that the LED box 10 has a regular shape and is convenient for splicing. Of course, the number of display modules 110 may also be an odd number. For example, in some special installation positions or for a specific display effect, the specifications of the cabinets need to be irregular, and an odd number of display modules 110 may be required. Of course, when the display module 110 is large enough to be compatible with the specifications of the box frame 120 , only one display module 110 may be provided. However, considering that a large display module 110 needs to be equipped with a large enough light board, the large light board is easily damaged/deformed, and for later maintenance and disassembly, it is advantageous to configure multiple display modules 110 in one box. For example, in the embodiment shown in FIG. 1 , there are four display modules 110 arranged in a 2×2 array.

The display module 110 may include a connector 112 , a HUB board 130 is disposed in the box frame 120 , and the connector 112 is electrically and data connected to the HUB board 130 to realize the display control of the display module 110 .

The display module 110 can be a standard module, so that any one of the display modules 110 can be installed in any installation position after being disassembled. Considering that the positions of the connectors 112 of the display modules 110 are different, the display modules 110 can also have various specifications, and the display modules 110 of the same specification can be replaced and installed. For example, in the embodiment shown in FIG. 3 , only one HUB board 130 is configured in the LED box 10 , the HUB board 130 is arranged in the center, and the four display modules 110 are all connected to the HUB board 130 . The display modules 110 located on both sides of the HUB board 130 have different positions of the connectors 112 connected to the HUB board 130. Therefore, the display modules 110 can have two specifications. The display modules 110 on both sides of the HUB board 130 have different specifications. The display modules 110 on the same side have the same specifications. Of course, by adjusting the position of the connector 112, the specifications of the display modules 110 on both sides of the HUB board 130 can also be made the same.

The installation channel 140 may be an actual pipe with a solid body, or it may be a virtual set up and present as an area through which the installation tool 20 can freely pass. For example, when there is no electronic component blocking between the two splicing holes 123, the two splicing holes 123 are connected through a cavity. At this time, the part of the cavity between the two splicing holes 123 is the installation channel 140. Therefore, from a practical point of view, the mounting channel 140 is not actually provided, that is, the mounting channel 140 is virtually provided and is a part of the cavity.
