Abstract:
A display includes: display elements; drive electrodes; touch detection electrodes each forming an electrostatic capacitance with corresponding one of the drive electrodes; and a drive section applying an AC drive signal to the drive electrodes during each of a plurality of touch detection periods, the AC drive signal involving multiple transition to generate one or more transition timing pairs. The AC drive signal includes at least a first transition timing pair and a second transition timing pair over the plurality of touch detection periods. The first transition timing pair has a first transition interval, and the second transition timing pair has a second transition interval different from the first transition interval.
