Patent attributes
A touch screen display includes a display, a video graphics processing module, electrodes, and drive-sense circuits. The electrodes integrated into the display, which is operable to render frames of data into visible images. The video graphics processing module is operably coupled to generate the frames of data. The drive-sense circuits, when enabled and concurrent with the display rendering the frames of data into the visible images, monitor sensor signals on the electrodes. A sensor signal includes a drive signal component and a receive signal component. The drive-sense circuits generate the drive signal components of the sensor signals and the receive signal components are representation of impedances of the electrodes. A change in impedance is indicative of a proximal touch to the touch screen display.
