Patent ID: 8803840

Claim:
A touch panel comprising: a first conductive film divided into multiple 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 that is perpendicular to the pair of electrodes and 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 all regions, 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 without discharging the voltage applied to the pair of electrodes, discharge the voltage applied to the pair of electrodes after detecting one of the X-coordinate and the Y-coordinate in all regions, and detects the other of the X-coordinate and the Y-coordinate in all regions by applying a voltage to the another pair of electrodes after discharging the voltage applied to the pair of electrodes.
