Abstract:
According to an aspect, a display device with a touch detection function includes: a pixel electrode; a touch detection electrode; a display drive unit for outputting the pixel signal to the pixel electrode in synchronization with a display drive signal; an operation drive unit for supplying the display drive signal in a display operation period to perform a display operation and supplying a touch detection drive signal in a touch detection period to perform a touch detection operation; a touch detection unit for detecting a detection signal outputted from the touch detection electrode; and a control unit for executing the display operation period and the touch detection period in a time divisional manner. The touch detection unit performs a noise detection operation for detecting a disturbance noise superimposed on the touch detection electrode in the display operation period.
