More Information
Summary:A touch screen display includes a plurality of sets of electrodes facilitating touch sense functionality based on electrode signals having a drive signal component and a receive signal component. Each set of electrodes includes a corresponding proper subset of non-neighboring ones of a plurality of row electrodes and a corresponding proper subset of non-neighboring ones of a plurality of column electrodes. The row electrodes and the column electrodes form a plurality of cross points. The touch screen display further includes a plurality of sets of drive-sense circuits, where each set of drive-sense circuits is operable to generate a proper subset of a plurality of sensed signals indicating variations in capacitance associated with a proper subset of the plurality of cross points formed by a corresponding set of electrodes. The touch screen display further includes a processing module operable to process the plurality of sensed signals identify a user interaction.
