Summary:Disclosed is a method for minimizing noise 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: performing a dummy scan to sense a signal from the sensing line in a state where a driving signal is not applied to the drive line; and comparing a threshold with a magnitude of a signal obtained through the dummy scan, and estimating noise in a first frequency band, i.e., a frequency of the driving signal.
