description The invention provides a driving method and device of a touch panel and a touch display device, and relates to the technical field of display. The first scanning signals are input to the first touch electrodes at the same time, the first induction signals of the second touch electrodes are received to determine the suspected columns, the second scanning signals are input to the second touch electrodes at the same time, and the second induction signals of the first touch electrodes are received to determine the suspected rows, according to the suspected columns and the suspected rows, a suspected touch area is determined, third scanning signals are sequentially input into all the first touch electrodes in the suspected touch area row by row, and third induction signals of all the second touch electrodes in the suspected touch area are received to determine the touch position. Therefore, the time required for determining the suspected row and the suspected column in the first two frames is greatly shortened, so
