For 8- and 4-wire touch screens, the point at which the contact is made can be determined by
measuring a voltage driven between the bus bars on the X-axis layer through either or both of
the Y lines, and by then measuring a voltage driven between the bus bars on the Y-axis layer
through either or both of the X lines. By comparing these voltages to values determined
during calibration, the location of the touch can be determined.
