Patent attributes
A differential touch screen display includes a display, a plurality of differential electrode pairs integrated into the display, a plurality of differential drive-sense circuits, and a processing module. When enabled, a set of differential drive-sense circuits of the plurality of differential drive-sense circuits is operable to provide a set of differential electrode signals to a set of differential electrode pairs of the plurality of differential electrode pairs and generate a set of analog receive signals representative of electrical characteristic changes of the set of differential electrode pairs. The processing module is operable to interpret the electrical characteristic changes as one or more of a self capacitance of one or more of: a row differential electrode pair and column differential electrode pair of the set of differential electrode pairs and a mutual capacitance at a crossing between one or more row differential electrode pairs and column differential electrode pairs.
