Display device and method of driving display device

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 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 from 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 from the second control unit, and
• 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.
