  • Patent number: 11301097
    Abstract: A touch-screen-controller (TSC) performs mutual sensing to acquire touch strength values from a touch matrix formed by capacitively intersecting conductive lines. For each line, the TSC generates an emulated self capacitance value from an associated touch strength value based upon a position of that line compared to a location on the touch matrix adjacent to which a first touch type is expected to occur, and determines presence of the first touch type adjacent to the touch matrix based upon the emulated values. The emulated values for each conductive line may be weighted based upon its closeness to the location where the first touch type is expected to occur. The weighting may be zero if its associated conductive line is outside of the location where the first touch type is expected to occur, and may be one if inside of the location where the first touch type is expected to occur.
