Touch device and driving method for touch control device
Disclosed are a touch device and a driving method thereof. The touch device includes a touch screen, a detection circuit and a driving circuit, the touch screen including a common electrode, an induction electrode and a pixel electrode, the detection circuit including a first input terminal, a second input terminal and an output terminal, the first input terminal being connected with the induction electrode; during a display period, the common electrode is configured to load a common electrode signal outputted by the driving circuit, the pixel electrode is configured to load a pixel electrode signal outputted by the driving circuit, a display electric field is generated between the common electrode and the pixel electrode, the reference signal is the same as the common electrode signal. In this disclosure, no voltage difference is generated between the common electrode signal and the reference signal, and thus avoiding affecting the normal display of the touch device.
