Abstract
A method for sensing touch on a touch panel including a plurality of drive lines and a plurality of sensing lines, wherein the drive lines and the sensing lines cross each other, the method including: applying parallelly sensing signals having mutually different frequencies to at least two out of a plurality of the drive lines; and separating only a signal having a specific frequency from signals outputted from the sensing line.
