1. A method of controlling a display device, the method comprising:
generating a plurality of Average Picture Level (APL) data for each specific period within a vertical blank period by a first display module;
transmitting the plurality of the APL data to a second display module at a specific timing point by the first display module;
receiving the plurality of the APL data by the second display module; and
processing image data by the second display module based on a specific APL data among the plurality of the received APL data,
wherein the second display module receives timing signals including a vertical synchronization signal and a horizontal synchronization signal, and
wherein a control field frame is transmitted during a period in which both of the vertical synchronization signal and the horizontal synchronization signal have a low state.
