SOURCE DRIVER OF DISPLAY DEVICE, AND METHOD OF CONTROLLING THE SAME

A source driver having a cascade connection configuration that drives signal lines of a display device according to a plurality of signals transmitted by a mini-LVDS interface from a controller during a predetermined period corresponding to a cascade signal received from a preceding stage, the source driver including a first reception circuit receiving a first signal of the plurality of signals; a second reception circuit receiving a second signal of the plurality of signals; and an enable control circuit that controls each of the first and second reception circuits to one of an active state and a standby state; in which the enable control circuit sets the second reception circuit to the active state according to the cascade signal received from the preceding stage, and sets the first and second reception circuits to the standby state according to a cascade signal output by the source driver to a subsequent stage.
