Abstract:
According to an aspect, a display device with a touch detection function includes: a display area where a plurality of pixel electrodes are arranged; drive electrodes provided so as to face the pixel electrodes; a control device for performing image display control; a touch detection electrode facing the drive electrodes; a touch detection unit for detecting a position of a proximity object; a wiring arranged in a frame area positioned outside the display area; and a plurality of selection switches for selecting the drive electrodes to be coupled to the wiring based on a selection signal of the control device. The control device supplies the display drive voltage and a touch drive signal to the same wiring at different times.
