To obtain a driving method and a touch input method for the touch panel which make it easy to recognize a double touch on the touch panel by tapping different positions with a 1st and a 2nd depressing means and judging whether or not the double tapping is done at a desired position.
The index fingers 34 is pressed against the inside of the frame of an icon 36 and the position where the index finger 34 is placed is outputted from the touch panel 32 (a). Then while the index finger 34 is depressed against the icon 36 on the touch panel 32, another position on the touch panel 32 is tapped with the middle finger 40. The touch panel 32 outputs the position indicated with the tip of the arrow 42 in a figure, i.e., a position nearby the mid-point on the line connecting the index finger 34 and middle finger 40 (b). When the index finger 34 is placed only on the icon 36 on the touch panel 32, the touch panel 32 outputs the position where the index finger 34 is placed as shown with the tip of an arrow 44, so that the double tapping is recognized (c).
