Abstract
A method for filtering signals of a touch sensitive device is used to judge whether or not a touch signal output from a touch sensitive device is noise by utilize the arrangement pattern of sensing areas. If the sensing areas corresponding to the touch signal are arranged partially conforming to a noise arrangement pattern the touch signal will be discarded. The present invention uses a scheme of comparing the arrangement diagram of a touch signal with a plurality of noise arrangement patterns to decide whether or not to discard the touch signal so as to increase the accuracy and the stability of a capacitive touch sensitive device.
