1. A tiling display apparatus comprising:
a set board configured to generate a control command signal; and
a plurality of display modules connected to one another through a first interface circuit based on a serial communication scheme and executing a target operation corresponding to the control command signal,
wherein the first interface circuit is implemented with a bidirectional serial interface having a feedback loop type between adjacent display modules of the plurality of display modules,
wherein the first interface circuit is distinguished from a separate interface circuit for transmitting an input image between the adjacent display modules, and
wherein the first interface circuit includes a first transmission cable, and the separate interface circuit includes a separate transmission cable physically separated from the first transmission cable.
