Abstract:
In a display apparatus, a touch panel where driving and sensing electrodes face each other across a dielectric substance outputs a detection signal from the sensing electrode in synchronization with a driving signal applied to the driving electrode. A pointing device points to a position on a touch surface of the touch panel. A detection assisting device includes an inverting circuit for obtaining a detection driving signal corresponding to the driving signal and inverting the phase thereof to generate an inversion signal, and outputs the inversion signal to the sensing electrode via the pointing device. A control device applies the driving signal to the driving electrode, obtains the detection signal generated at the sensing electrode according to the mutual capacitance between the driving and sensing electrodes and the inversion signal, and detects the pointing device in contact with or proximity to the touch panel based on the detection signal.

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.
