Thereafter, the processor 130 of the preset display device transmits the identification information set to (0,0) to the display device 100 connected to the preset display device.

In addition, the display apparatus 100 connected to the preset display apparatus is identification information of the neighboring display apparatus included in the received identification information (in this case, the neighboring display apparatus is a preset display apparatus and the identification information is (0,0)). ) And identification information corresponding to the display apparatus 100 may be allocated based on the positional relationship with the adjacent display apparatus.

For example, when the display apparatus 100 is connected to the side of the preset display apparatus, the processor 130 of the display apparatus 100 may open the column area 520 of the identification information (0,0) received from the preset display apparatus. By increasing the value from 0 to 1, identification information corresponding to the display apparatus 100 may be allocated to (0, 1).
