Provided is a touch driving method for a touch display device. The touch display device includes a display panel and a touch panel. The touch panel is disposed on the display panel. The touch panel includes a first driving electrode and a second driving electrode. The touch driving method includes: a first touch driving signal is provided to the first driving electrode, and a second touch driving signal is provided to the second driving electrode; a sum of a voltage value of the first touch driving signal and a voltage value of the second touch driving signal is adjusted to continue to be equal to a set voltage value in a mutual-capacitance sensing stage of a mutual-capacitance sensing mode; and the first touch driving signal and the second touch driving signal are adjusted to be a third touch driving signal in a self-capacitance sensing stage of a self-capacitance sensing mode.
