    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.
