Abstract:
A display device with a touch detection function includes a control device that performs, in normal operation mode, image display control so as to exhibit an image display function of a display function layer based on an image signal and performs touch detection control; a touch detecting unit that detects, in the normal operation mode, a position of an object in proximity to or in contact with the touch detection electrode based on a detection signal transmitted from the touch detection electrode; and a touch-detection controller that detects, in sleep mode, the proximity of the object to or the contact thereof with the touch detection electrode. When the touch-detection controller detects the proximity of the object to or the contact thereof with the touch detection electrode in the sleep mode, the control device controls a pixel electrode to a predetermined potential, and thereafter supplies a touch drive signal to a drive electrode.
