Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a display panel including:
a display screen on which an image is displayed; and
a sensor unit configured to detect a touch operation on the display screen;

a first control unit configured to supply a first signal to the display panel to display the image; and
a second control unit configured to calculate touch information related to the touch operation based on a sensor signal received from the sensor unit and to supply the touch information to the first control unit, wherein
the first control unit includes:
a signal generator configured to generate the first signal based on an image signal supplied by an external image signal supply source; and
an overdrive circuit configured to perform a process of increasing an amplitude of the first signal generated by the signal generator,

the overdrive circuit is actuated based on the touch information received from the second control unit,
the first control unit, in response to the actuation of the overdrive circuit, supplies the first signal having the amplitude increased by the overdrive circuit to the display panel,
the first control unit determines, based on the touch information received from the second control unit, whether the touch operation is being performed,
the overdrive circuit is actuated in response to a determination that the touch operation is being performed, and
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.
