Abstract
A capacitive touch screen display operates by: receiving a plurality of sensed signals indicating variations in mutual capacitance associated with a plurality of cross points formed by a plurality of electrodes of a sensor layer adjacent to a compressible dielectric layer adjacent; generating capacitance image data associated with the plurality of cross points that includes positive capacitance variation data corresponding to positive variations of the capacitance image data from a nominal value and negative capacitance variation data corresponding to negative variations of the capacitance image data from the nominal value; and processing the negative capacitance variation data to determine a compressive touch condition of the touch screen display by a non-conductive object.
