ABSTRACT:
An electroluminescent lamp includes a continuous electroluminescent dielectric layer and a patterned rear electrode overlying the electroluminescent dielectric layer, wherein the rear electrode includes at least two conductive segments separated by a gap. An insulating layer fills the gap and a conductive interconnect overlies the insulating layer, joining the segments. The insulating layer spaces the interconnect from the electroluminescent dielectric layer a sufficient distance to reduce the electric field in the electroluminescent dielectric layer below the point at which the lamp appears luminous.
