Abstract
An electroluminescent device used as an illumination source in a scanner, including a plurality of electroluminescent elements, each having a transparent electrode with a top surface, a radiation generating stack under the transparent electrode, and a second electrode under said radiation generating stack. A voltage source having a plurality of phase characteristics is coupled across the electrodes of each of the electroluminescent elements to apply a voltage to each of the electroluminescent elements.
