Abstract
A touch panel includes: a first conductive film divided into regions insulated from each other; a second conductive film facing and located away from the first conductive film; a pair of electrodes provided to the second conductive film, the electrodes facing each other; another pair of electrodes provided to the second conductive film, the electrodes facing each other; and a control unit configured to determine whether the first conductive film contacts with the second conductive film in each region, detect one of an X-coordinate and a Y-coordinate of a point where the first conductive film contacts with the second conductive film by applying a voltage to the pair of electrodes in a case where the first conductive film contacts with the second conductive film, discharge the voltage applied to the pair of electrodes after detecting one of the X-coordinate and the Y-coordinate in each region, and detects the other of the X-coordinate and the Y-coordinate in each region by applying a voltage to the another pair of electrodes after discharging the voltage applied to the pair of electrodes.
