A touch display drive method, a drive device and a touch display in the field of display technologies. The touch display drive method comprises inputting a display drive signal and a touch scanning signal to an electrode array While the display drive signal is being input, the touch scanning signal is input for touch scanning. Each touch scanning signal line for inputting the touch scanning signal generates a coupling signal for electrodes in the same column, and two coupling signals generated by two of touch scanning signal lines in the same column offset each other. The method solves problems with the display and touch control caused by insufficient time due to time-division driving.
