Abstract
A display device with a touch detection function includes, a plurality of display elements performing display operation based on a pixel signal and a display drive signal, a touch detection element detecting an external proximity object based on a touch detection drive signal, a scan drive section performing display scanning by sequentially supplying the pixel signal and the display drive signal to the plurality of display elements in a time-divisional manner, and the scan drive section supplying the touch detection drive signal to the touch detection element, and a touch detection circuit performing touch detection by sampling a detection result from the touch detection element with a period shorter than a period of the display scanning. The scan drive section supplies the touch detection drive signal to the touch detection element in a touch detection operation period different from a display operation period for performing the display scanning.
