| 1. A method of receiving data signals over data lines at a plurality of data driver circuits, the method comprising:
organizing said data lines into groups, each group including N input data lines, wherein N is a non-zero, positive integer,
and each group being associated with one of the plurality of data driver circuits;
associating M reference lines with each group of N input data lines, wherein M is a non-zero, positive integer and N>M; and
receiving, at each of the plurality of data driver circuits, N data signals on said N input data lines and M reference signals
on said M reference lines; and
determining, at each of the plurality of data driver circuits, data values on said N data lines according to differences between
currents on said N input data lines and currents on said M reference lines, respectively.
