Abstract
The present invention provides a method of forming an electroluminescent circuit by screen printing. The method according to the invention includes screen printing a rear electrode pattern on a substrate, which is preferably a polyester sheet, screen printing a dielectric layer over the rear electrode pattern, screen printing a front electrode pattern on the dielectric layer, and screen printing a phosphor layer over the front electrode layer. The rear electrode pattern preferably includes a solid layer disposed upon the substrate and the front electrode pattern preferably includes a plurality of opaque lines separated by spaces. In an alternative embodiment, the method according to the invention includes screen printing the phosphor layer on the substrate, screen printing the front electrode pattern on the phosphor layer, screen printing the dielectric layer over the front electrode pattern, and screen printing the rear electrode pattern over the dielectric layer.
