Electroluminescent display and method for production
The present invention relates to an electroluminescent display. The display includes a front conductive layer, a first dielectric layer, a light emitting layer, a second dielectric layer, and a rear conductive layer. The rear conductive layer defines a continuous void, where the void separates the rear conductive layer into a first area to be energized to electroluminate and a second area that is not energized.
1. An electroluminescent display comprising:
a front conductive layer;
a first dielectric layer;
a light emitting layer;
a second dielectric layer; and
a rear conductive layer defining a continuous void, wherein the void separates the rear conductive layer into a first area to be energized to electroluminate and a second area that is not energized.
2. The electroluminescent display of claim 1 , wherein the rear conductive layer is formed of aluminum foil.
3. The electroluminescent display of claim 1 , wherein the continuous void is die-cut from the rear conductive layer.
4. The electroluminescent display of claim 1 , wherein the rear conductive layer is applied to a substrate.
5. The electroluminescent display of claim 4 , wherein the substrate is a packaging material.
6. The electroluminescent display of claim 5 , wherein the packaging material is paperboard.
7. The electroluminescent display of claim 1 , wherein the light emitting layer is formed of phosphor.
8. The electroluminescent display of claim 1 , wherein the front conductive layer is made of a material that is light-transmissive.
