Abstract:
A touch screen display includes a display, a video graphics processing module, electrodes integrated into at least a portion of the display, and drive-sense circuits coupled to the electrodes. The drive-sense circuits, when enabled and concurrent with the display rendering frames of data into the visible images, detect changes in electrical characteristics of electrodes. At least some drive-sense circuits monitor sensor signals on at least some electrodes. A sensor signal includes a drive signal component and a receive signal component. The at least some drive-sense circuits generate the drive signal components of the sensor signals. The receive signal component is a representation of a change in an electrical characteristic of an electrode of the at least some electrodes when a corresponding drive signal component is applied to the electrode. The change in the electrical characteristic of the electrode is indicative of a proximal touch to the touch screen display.
