1. A display system comprising:
a host configured to transfer image data respectively corresponding to a plurality of frames through a main channel, and to transfer a synchronization signal that synchronizes a clock signal of the host with a clock signal of the display driving circuit, the synchronization signal transferred through an auxiliary channel;
a display panel configured to display the image data; and
a display driving circuit configured to generate control signals driving the display panel, based on the synchronization signal received through the auxiliary channel,
wherein the host is configured to transfer the synchronization signal that includes a first synchronization signal and a second synchronization signal that is different from the first synchronization signal, to the display driving circuit, through the auxiliary channel.
