Abstract
An X-side resistive film and a Y-side resistive film of a touch panel face each other with a predetermined gap therebetween. Resistance values of the X-side and Y-side resistive films are measured with connections to the X-side and Y-side resistive films being alternately switched. X and Y coordinates of a contact position of the X-side resistive film and the Y-side resistive film are detected based on the measured resistance values. Amounts of current applied to the X-side and Y-side resistive films during on-periods of the X-side and Y-side connections are set to be different from each another in accordance with resistance values corresponding to the X-side and Y-side resistive films, respectively.
