Abstract
Abstract An electroluminescent apparatus comprises a substrat (12); a first conductor (14) fixed to the substrate (12) in a preselected pattern to form a first electrode; a luminescent coating (16) covering a first portion (18) of the first conductor (14) while leaving a second portion (20) of the first conductor uncovered; and a pair of second conductors (22, 24) situated adjacent to, but separated from, each other on the substrate (12), wherein one (22) of the pair of second conductors (22 and 24) contacts a selected one of the group consisting of the luminescent coating (16) and the first conductor (14), and wherein the other (24) of the pair of second conductors (22, 24) contacts the unselected one of said group. A method of forming the electroluminescent device is also described.
