Abstract
A display device according to the present disclosure includes a panel unit including common electrodes for common use in image display and touch detection, a drive circuit configured to output a touch drive signal to each of the common electrodes, and a touch detection circuit configured to detect touch of an object onto the panel unit based on a detection signal received from each of the common electrodes. In a unit frame period, display periods and touch detection periods each including first and second sections are alternately placed. In the touch drive signal in each touch detection period, amplitude values of pulses included in the first section change from a first value to a second value larger than the first value, across the first section, and amplitude values of pulses included in the second section change from the second value to the first value across the second section.
