Claim 0:
1. A touch screen display comprises:
a display configured to render frames of data into visible images;
a plurality of sets of electrodes integrated into the display to facilitate touch sense functionality based on electrode signals having a drive signal component and a receive signal component, wherein each set of electrodes of the plurality of sets 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, wherein the plurality of row electrodes is separated from each the plurality of column electrodes by a dielectric material, and wherein the plurality of row electrodes and the plurality of column electrodes form a plurality of cross points;
a plurality of sets of drive-sense circuits, wherein each set of drive-sense circuits of the plurality of sets of drive-sense circuits includes a plurality of drive-sense circuits coupled to electrodes of a corresponding set of electrodes of the plurality of sets of electrodes, and wherein each set of drive-sense circuits is operable to generate a set of sensed signals indicating variations in capacitance associated with a proper subset of the plurality of cross points formed by the corresponding set of electrodes; and
a processing module that includes at least one memory that stores operational instructions and at least one processing circuit that executes the operational instructions to perform operations that include:
operating in a first mode during a first temporal period based on:
activating exactly one set of drive-sense circuits of the plurality of sets of drive-sense circuits to generate a corresponding one set of sensed signals during the first temporal period;
receiving the corresponding one set of sensed signals from the exactly one set of drive-sense circuits during the first temporal period; and
processing the corresponding one set of sensed signals to generate first proximal interaction data for the first temporal period; and

operating in a second mode during a second temporal period after the first temporal period based on:
activating more than one set of drive-sense circuits of the plurality of sets of drive-sense circuits to generate a corresponding more than one set of sensed signals during the second temporal period;
receiving the corresponding more than one set of sensed signals from the more than one set of drive-sense circuits during the second temporal period; and
processing the set of sensed signals to generate second proximal interaction data for the second temporal period.
