Abstract:
According to an aspect, a touch detection apparatus includes: a plurality of drive electrodes, wherein at least one of the drive electrodes includes a plurality of subdivided electrodes; a plurality of first touch detection electrodes; a second touch detection electrode; a first shift register circuit in which a plurality of first shift signal output circuits are sequentially coupled to one another; a second shift register circuit in which a plurality of second shift signal output circuits are sequentially coupled to one another; and a selection circuit that supplies a signal of the first shift register circuit to the drive electrode in a first mode, and supplies a signal of the second shift register circuit to the subdivided electrode in a second mode.
