A polymer electroluminescent display is provided which comprises a number of individual light-emitting elements in a selected formation and adapted for excitation from a voltage supply. The formation, which is formed on a substrate, includes copper conductors etched onto the substrate. a plurality of polymer dielectrics with relatively high dielectric constant are screen printed over the conductors, with each dielectric corresponding to an individual light-emitting element. A plurality of light-emitting polymer phosphors are screen printed over the dielectrics with each phosphor corresponding to an individual light-emitting element. A polymer indium oxide light-transmissive conductor is screen printed over each phosphor. A polymer dielectric with a relatively low dielectric constant separates each of the individual light-emitting elements from each other and alleviates cross-talk between the individual light-emitting elements. A conductive silver polymer ink is printed over the light-transmissive conductor with portions of the silver polymer defining window openings for enabling viewing of the phosphor through the light-transmissive layer when the phosphor is excited. Voltage excitation by a dynamic voltage supply across a selected copper conductor and the silver polymer will cause light emission by the light-emitting element at the excited location.

A polymer electroluminescent display which comprises: a number of individual light-emitting elements in a selected formation and adapted for excitation-from a voltage supply; said elements being formed on a substrate and said display comprising a first electrical conductor overlying the substrate; a first polymer dielectric located complementary with the first electrical conductor and separating each of the individual light-emitting elements from each other, said first dielectric polymer having a relatively low dielectric constant; a second polymer dielectric having a dielectric constant that is substantially higher than the dielectric constant of said first polymer dielectric; a light-emitting phosphor polymer overlying said second dielectric; a second electrical conductor overlying the phosphor and defining a window for enabling viewing of the phosphor; whereby voltage excitation by the voltage supply across the first electrical conductor and the second electrical conductor will cause light emission by the excited phosphor polymer.
