Signs including electroluminescent lamps are described. In accordance with one embodiment of the present invention, electroluminescent lamps are coupled to a sign by first forming a rear electrode on a front surface of the sign. After forming the rear electrode on the sign, a dielectric layer is screen printed over the rear electrode, and a phosphor layer is screen printed over the dielectric layer. A layer of indium tin oxide ink is then screen printed to the phosphor layer to form an EL lamp. |
