1. Control circuitry for a touch panel, the control circuitry comprising:

  • a touch panel interface;

    a memory comprising touch positioning logic; and

    a controller in communication with the memory and the touch panel interface, the controller configured, when the touch positioning logic is executed, to;

    scan a touch panel;

    determine a first touch panel blob and a second touch panel blob from the scan;

    determine that the first touch panel blob and the second touch panel blob share a common member pixel;

    apportion capacitance of the common member pixel between the first touch panel blob and the second touch panel blob; and

    determine a position of the first touch panel blob, the second touch panel blob, or both, taking into consideration the capacitance that was apportioned between the first touch panel blob and the second touch panel blob.
