Abstract
A method of detecting an application or removal of one of a first touch and a second touch on a capacitive touch screen is provided. The method may include storing respective first touch data for a first set of nodes at a first cycle, storing respective second touch data for a second set of nodes at a second cycle after the first cycle, determining a first total touch data by summing the respective first touch data for the first set of nodes at the first cycle, determining a second total touch data by summing the respective second touch data for the second set of nodes at the second cycle, and determining whether a touch has been applied or removed from the capacitive touch screen based on a comparison between the first total touch data and the second total touch data.
