Abstract
A display device includes: a display panel including a sensor unit configured to detect a touch operation; a first control unit configured to supply a first signal to the display panel; and a second control unit configured to calculate touch information related to the touch operation and to supply the touch information to the first control unit. 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. 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.
