Transparent contacts for organic devices

An organic light emitting device structure comprising:

• a substrate layer comprising a first transparent electrically conductive coating deposited on a surface;
• a first light emitting device deposited on the first transparent electrically conductive coating;
• a second transparent electrically conductive coating deposited on the surface of the first device not in contact with the first coating;
• a second light emitting device deposited on the surface of the second coating;
• a third transparent electrically conductive coating deposited on the surface of the second device not in contact with the second coating;
• a third light emitting device deposited on the surface of the third coating, wherein the first, second, and third light emitting devices each include an organic emission layer for emitting light of a desired color, respectively;
• and
• a fourth transparent electrically conductive coating deposited on the surface of the third device not in contact with the third coating.
