Abstract:
According to an aspect, a display device with a touch detection function includes: a scan drive unit that supplies a touch drive signal to a touch detection element in a touch detection operation period different from a display operation period in which a pixel signal and a display drive signal are sequentially supplied to display elements to perform display scanning; and a noise detector that detects noise included in a frequency component sampled by a touch detection unit. When the noise detector detects the noise, the scan drive unit changes a frequency of the touch drive signal in the touch detection operation period and supplies the changed frequency to the touch detection element.
