Abstract

A device, having a touch screen display, performs a mutual capacitance scan of rows and columns of an array of capacitive touch sensors associated with the touch screen display. The device selects a subset of the rows, and a subset of the columns, of the array of capacitive touch sensors, and performs a self capacitance scan of the selected subset of the rows, and the selected subset of the columns, of the array of capacitive touch sensors based on results of the mutual capacitance scan. The device identifies an accidental or false touch input on the touch screen display based on results of the self capacitance scan.
