1. A driver apparatus for an electroluminescent display comprising a plurality of rows to be scanned and a plurality of columns which intersect said rows to form a plurality of pixels, said driver apparatus comprising:

  • addressable row drivers applying an output voltage to the rows, the value of which is greater than the threshold voltage for the electroluminescent display and less than that required to provide the maximum desired luminance for a pixel; and

    bipolar column drivers supplying an output voltage to the columns, the output voltage being either a positive or negative voltage depending on the desired luminance of the pixels.
