1. A data transmission method of a display driving apparatus, the data transmission method comprising:
obtaining display data and command data;
transmitting the display data and the command data to each of a plurality of display driver integrated circuits (ICs) through a mobile industry processor interface (MIPI) using a point-to-multipoint (multi-drop) manner; and
independently controlling sub-pixels corresponding to each of the plurality of display driver ICs based on the display data and the command data,
wherein the controlling comprises:
receiving the display data and the command data by a receiving interface included in each of the plurality of display driver ICs; and
controlling the sub-pixels by selectively writing the display data and the command data by a logic controller included in each of the plurality of display driver ICs.
