Abstract
A touch detection method includes performing a detection method to obtain a signal point along with a signal value and a signal state, wherein the signal state has a positive state generated by proximity touch and a negative state by generated by impurity touch; checking a previous signal state generated by previous detection method and a current signal state generated by current detection method; comparing the previous signal state and the current signal state, and counting a number when the signal states of the previous signal state and the current signal are the same; determining if the number is greater than a threshold; and proceeding a base signal updating when the number is greater than the threshold.
