More Information
Summary:A capacitive touch screen display operates by: providing a display configured to render frames of data into visible images; providing 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; generating, via a plurality of drive-sense circuits coupled to at least some of the plurality of electrodes, a plurality of sensed signals; receiving the plurality of sensed signals; generating capacitance image data associated with the plurality of cross points that includes capacitance variation data corresponding to variations of the capacitance image data from a nominal value; and processing the capacitance image data to determine a touchless indication proximal to the touch screen display based on a touchless indication threshold.
