Classification: CPC G | IPC G

Claim 5:
6. A method of driving a display device including a display panel having a touch panel function, the method comprising:
generating, based on an image signal supplied by an external image signal supply source, a first signal to display an image;
calculating touch information related to a touch operation based on a sensor signal supplied by a sensor unit that detects the touch operation on a display screen;
determining, based on the touch information, whether the touch operation is being performed; and
in response to a determination that the touch operation is being performed, actuating an overdrive circuit that performs a process of increasing an amplitude of a first signal and supplying the first signal having the amplitude increased by the overdrive circuit to the display panel,
wherein the overdrive circuit remains actuated from a point of time at which the determination is made that the touch operation is being performed until a point of time at which a determination is made that no more touch operation is being performed.
