Touch-panel device

摘要

Provided is a touch-panel device capable of detecting a touched position with high accuracy even when a touched area extends off an electrode area. According to the present invention, the touched area is assumed to be, for example, a circular in shape. A width (46) in an X direction and a width (47) in a Y direction of an area where the touched area in a circular shape and an electrode area (6) overlap each other may be determined based on sensor measured values. When the overlap width (46) in the X direction and the overlap width (47) in the Y direction are different from each other, it is judged that the touched area extends off the electrode area (6), and a position of a center of the touched area in the circular shape is calculated as the touched position.
