The method of claim 4 wherein the depositing and patterning step includes depositing and patterning at least one layer and providing different dyes in different patterned portions corresponding to different colored light emitting pixels so that when an electrical potential is applied between the anode and cathode different colored light emitting pixels will be produced. 6. The method of claim 4 wherein the dopant layer is patterned by: ink jet printing, thermal dye diffusion printing, offset printing, or wax transfer printing. 7. The method of claim 4 wherein the dopant layer is patterned by vacuum depositing dopant material through an aperture mask.
