Position detection device, and position detection method based on electromagnetic inductive coupling and capacitive coupling

Abstract

A position detection device includes a plurality of first electrodes extending in a first direction; and detection circuitry. The detection circuitry is configured to simultaneously select two adjacent first electrodes, from the plurality of first electrodes, in a state of electromagnetic inductive coupling with a pointer to detect a position indicated by the pointer. The detection circuitry, at a first timing, simultaneously selects Kth first electrode and (K+1)th first electrode as two adjacent first electrodes; and at a second timing, simultaneously selects the (K+1)th first electrode and (K+2)th first electrode as the two adjacent first electrodes.
