  • Patent number: 11054958
    Abstract: An apparatus comprises touch screen interface and signal processing circuit. Within touch screen interface, there are switching circuits configured to be coupled to at least one of a plurality of column electrodes, and there are touch detection circuits configured to be coupled to at least one of a plurality of row electrodes. The signal processing circuit is coupled to each switching circuit and each touch detection circuit so as to be able to selectively activate the plurality of switching circuits and touch detection circuits to identify a zone for a touch event. The signal processing circuit determines first, second, third, and fourth resistances for the zone for the touch event and determines a set of coordinates and pressure for the touch event from its first, second, third, and fourth resistances wherein an aperture filter register is in a host interface that also stores the first digital representation.
