Abstract
A touch panel includes a plurality of columns of sensing partitions, a plurality of driving lines, a plurality of sensing lines and a memory. A method for the touch panel to generate a touch signal includes sequentially inputting driving signals to the plurality of driving lines, reading a plurality of voltage values of one of the plurality columns of sensing partitions through one of the plurality of sensing lines, converting the plurality of voltage values into a plurality of digital values, calculating a mean of the digital values, and storing the coordinate of at least one digital value in a memory. The difference between the at least one digital value and the mean is larger than a predetermined value.
