Abstract
A touch display screen and a touch driving detection method thereof are provided. The touch display screen includes a touch module and a display module. The touch module includes a touch electrode unit and a touch driving detection unit, a touch signal for acquiring a change in capacitance is transmitted between the touch driving detection unit and the touch electrode unit. The display module includes a display electrode unit and a display driving unit, the display driving unit transmits a display driving signal to the display electrode unit. A potential of the touch signal is dynamically adjusted based on potential information of the display driving signal of the display driving unit, or a potential of the display driving signal is dynamically adjusted based on potential information of the touch signal of the touch driving detection unit.
