Abstract
A display device is configured in a display state to allow the common electrode to function as an electrode for display and a scanning electrode for a touch panel, to which a common voltage and a first scanning pulse voltage are supplied, and to allow a detection circuit to detect a touched position based on the voltage detected by the first and the second detection electrodes. In a display stop state, the first detection electrode is configured to function as a temporary scanning electrode, and the detection circuit is configured to supply a second scanning pulse voltage to the first detection electrode so as to detect existence of a swipe based on the voltage detected by the second detection electrode.
