Abstract
Each of a plurality of timing controllers has a synchronization reference signal output terminal from which a synchronization reference signal is output and a synchronization reference signal input terminal to which the synchronization reference signal is input. A master timing controller outputs a predetermined signal of display signals which are input from an external device, from the synchronization reference signal output terminal of the master timing controller as the synchronization reference signal, and the synchronization reference signal is input to the synchronization reference signal input terminals of the master timing controller and a slave timing controller. Accordingly, a luminance difference can be prevented from occurring between divided regions of a display panel due to asynchronization between display signals input to respective timing controllers in a display device in which a plurality of timing controllers are used and the display panel is divided into a plurality of regions.
