Abstract
A touch sensitive detecting method, applicable to a touch panel or screen, comprises: setting a sensing electrode to floating; after the sensing electrode is set to floating, setting at least one non-measuring sensing electrode to a sensing high voltage; measuring the voltage of the sensing electrode; setting the sensing electrode to a ground voltage and stopping measurement; and determining whether an externally conducted object is approximating or touching the touch panel or screen nearby the sensing electrode by comparing a difference between a threshold voltage and the measured voltage of the sensing electrode.
