US Patent 11188172 Detection apparatus

According to an aspect, a detection apparatus includes: a plurality of detection electrodes; a drive signal generation circuit configured to generate a drive signal; a detection circuit configured to be coupled to the detection electrodes to detect a detection signal based on the drive signal; and a first selection circuit. A first point in time when the drive signal makes a transition from a first potential to a second potential overlaps a first period in which the first selection circuit couples a detection electrode as a first selection target among the detection electrodes to the detection circuit. A second point in time when the drive signal makes a transition from the second potential to the first potential overlaps a second period in which the first selection circuit couples a detection electrode as a second selection target, which is not included in the first selection target, to the detection circuit.
