Abstract
A substrate has a self-illuminatable image. The substrate, which can be paper, will first receive conductive ink. The substrate can be calendered to provide a smooth, sealed surface for the ink. On top of the conductive ink, one or more dielectric layers can be provided followed by a phosphor-containing layer. A smoothing layer can then be provided. A second layer of conductive ink is provided on the smoothing layer. The conductive layers can be applied in any desired pattern. The first underlying conductive ink layer and the second overlying conductive ink layer will match the image in certain portions. When a current is passed through the conductive inks, phosphor in the phosphor-containing layer will be excited in order to illuminate the image. After printing of the first conductive layer, the substrate can be calendered to help connect conductive particles in the ink. A one-sided or two-sided display can be provided.
