1. A display module among a plurality of display modules included in a modular display apparatus, the display module comprising:
a communication interface; and
a plurality of driver integrated circuits (ICs),
wherein a first driver IC among the plurality of driver ICs is configured to:
based on obtaining a driving signal from an external device through the communication interface, provide the driving signal to a second driver IC adjacent to the first driver IC so that the driving signal is sequentially provided to remaining driver ICs among the plurality of driver ICs,
provide, to a second display module among the plurality of display modules, the driving signal based on module connection information including whether the second display module is connected to any one display module among the plurality of display modules by a daisy chain method, and
based on the any one display module being located at an end point among the plurality of display modules connected by the daisy chain method, not output the driving signal to outside.
