1. A touch screen display comprises:
a display configured to render frames of data into visible images;
a plurality 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 the plurality of electrodes includes a plurality of row electrodes and a plurality of column electrodes, wherein the plurality of row electrodes is separated from the plurality of column electrodes by a dielectric material and wherein the plurality of row electrodes and the plurality of row electrodes form a plurality of cross points;
a plurality of drive-sense circuits coupled to at least some of the plurality of electrodes to generate a plurality of sensed signals, wherein each the plurality of drive-sense circuits includes a first conversion circuit and a second conversion circuit, and wherein, when a drive-sense circuit of the plurality of drive-sense circuits is enabled to monitor a corresponding electrode of the plurality of electrodes, the first conversion circuit is configured to convert the receive signal component into a sensed signal of the plurality of sensed signals and the second conversion circuit is configured to generate the drive signal component from the sensed signal of the plurality of sensed signals;
a processing module that includes at least one memory that stores operational instructions and at least one processing circuit that executes the instructions to perform operations that include:
receiving the plurality of sensed signals, wherein the plurality of sensed signals indicate variations in capacitance associated with the plurality of cross points;
generating, based on the plurality of sensed signals, a stream of capacitance image data associated with the plurality of cross points that includes capacitance variation data corresponding to variations of capacitance image data in the stream of capacitance image data from a nominal value across a plurality of times within a temporal period; and
processing the stream of capacitance image data to detect a touchless gesture occurring within the temporal period.
