Abstract:
A display device is provided and having a touch detection function includes drive electrodes, detection electrodes, a display driver which performs a touch scanning drive and a display scanning drive, and a touch driver which obtains touch information including detection information on the closely situated external object by acquiring detection signals from the detection electrodes. The display driver acquires the image signal, which is input in response to a master synchronizing signal output to the outside, and outputs the touch synchronizing signal to the touch driver after a predetermined time elapses from time when the image signal is input. The touch driver starts to operate in response to the touch synchronizing signal from the display driver, to acquire the touch information, and outputs the touch information to the outside to cause production of the image signal to start.
