Abstract

A touch panel includes arranged touch electrodes, and a driver IC connected to each of the touch electrodes. The plurality of touch electrodes is grouped into a plurality of groups such that electrodes belonging to different groups are included in a range smaller than an object to be detected, such as a finger. The driver IC alternately or sequentially applies a driving voltage to the touch electrodes of the plurality of groups, detects a capacitance of each of the sensor electrodes, and detects, based on the detected capacitance, whether there is a touch.
