Abstract
Capacitance distribution between each of detection electrodes and a stylus pen on a touch panel is detected with a simple configuration. A read step and a detection step are included. In the read step, a switch element selected among a plurality of drive sense switch elements (DST) between detection electrodes (E) and drive sense lines (DS) aligned in an X-axis direction based on a code sequence via control lines (DSS) aligned in a Y-axis direction is made to turn on, and a linear sum signal is read from each of the detection electrodes (E). In the detection step, a capacitance is detected.
