Abstract

The luminosity of electroluminescent display pixels arranged at intersection regions between row and column electrodes is controlled so as to compensate for the effect of interelectrode coupling by reducing the voltage differentials applied between the row electrode being addressed and the column electrodes relative to those coresponding to initial pixel luminosity data contained in an incoming data stream, as a direct function of total row luminosity information extracted from that segment of the incoming data stream which pertains to the respective row.
