Abstract:
A display apparatus includes: a display face; a display function layer adapted to vary display on the display face in response to an inputted image signal; a plurality of driving electrodes disposed separately in one direction; a detection scanning control section configured to apply a detection driving voltage to some of the plural driving electrodes and carry out detection driving scanning while shifting an application object of the detection driving voltage in the one direction on the display face and then control the detection driving scanning such that jump shift of carrying out shift with a pitch of twice or more times a driving electrode pitch is included; and a plurality of sensor lines disposed separately in a direction different from the one direction and responding to touch or proximity of a detection object with or to the display face to exhibit an electric variation.
