Abstract
A method for filtering out signals of a touch device includes following steps: first, obtaining a touch signal; next, obtaining signal intensity values respectively corresponding to a first sensing area, a second sensing area and a third sensing area according to the above-mentioned touch signal, wherein the above-mentioned second sensing area is located between the above-mentioned first sensing area and third sensing area; then discarding the touch signal if the signal intensity value of the above-mentioned second sensing area is less than the signal intensity values of the first sensing area and the third sensing area. In this way to discard the noise signal, the present invention is able to increase the accuracy and the stability of a capacitive touch device.
