Abstract: A method for driving a touch panel that detects and compensates a double touch includes sequentially inputting coordinate values of touched points on the touch panel at predetermined time intervals, measuring a variation of the inputted coordinate values, determining the inputted coordinate values as a double touch when the measured variation is greater than a predetermined value, and compensating the inputted coordinate values if determined as a double touch.
