Claim:
1. A display apparatus comprising: a plurality of display elements including pixel electrodes; a plurality of drive electrodes facing the pixel electrodes; and; a plurality of touch detection elements including touch detection electrodes facing the drive electrodes; a driver unit configured to cause the display elements to display images and to cause the touch detection elements to detect a touch; and a control unit configured to cause the driver unit to: divide a frame in which images are displayed by the display elements, into a plurality of display periods; and determine a touch detection period between adjacent display periods in one frame, the touch detection period being a period in which the touch detection elements detect a touch, wherein the driver unit is configured to apply an AC driving signal to the drive electrode to be a target of the touch detection operation during the touch detection period so that the touch detection element makes the touch detection, is configured to apply a DC drive signal to all the drive electrodes, and is configured to apply a pixel signal to the pixel electrode to be a target of the display operation during the display period so that the display elements display an image, and wherein the control unit is configured to control the driver unit to have a first period in which the display period and the touch detection period are provided alternately, and a second period in which the display period is provided continuously.
