Abstract

See full text

A position detection system is provided including an electronic pen including M (M is a natural number) pen electrodes, and a sensor control circuit that is connected to a capacitance touch sensor including N (N is an integer equal to or greater than 2) sensor electrodes. The sensor control circuit controls transmission of uplink signals through the touch sensor. The electronic pen selects one or more reception electrodes from the M pen electrodes, and the sensor control circuit selects transmission electrodes that are L sensor electrodes satisfying 1
