Patent ID: 8470388

Claim:
A process for producing a conformal electroluminescent system, comprising the steps of: selecting a substrate; applying a base backplane film layer upon the substrate using an aqueous-based, electrically conductive backplane material; applying a dielectric film layer upon the backplane film layer using an aqueous-based dielectric material; applying a phosphor film layer upon the dielectric film layer using an aqueous-based phosphor material, the phosphor film layer being excited by an ultraviolet radiation source during application, the ultraviolet radiation source providing visual cues while the phosphor film layer is being applied, the application of the phosphor film layer being adjusted in response to the visual cues to apply a generally uniform distribution of the phosphor material upon the dielectric film layer; applying an electrode film layer upon the phosphor film layer using an aqueous-based, substantially transparent, electrically conductive electrode material, the backplane film layer, dielectric film layer, phosphor film layer, and electrode film layer each being applied by spray conformal coating; and further including the step of formulating a composition for the dielectric film layer, comprising: providing about a 2:1 solution of co-polymer and dilute ammonium hydroxide; pre-wetting a predetermined quantity of barium titanate in a predetermined quantity of ammonium hydroxide; and adding the pre-wetted barium titanate to the solution of co-polymer and dilute ammonium hydroxide to form a supersaturated suspension, wherein the phosphor film layer is excitable by an electrical field established across the phosphor film layer upon application of an electrical charge between the backplane film layer and the electrode film layer such that the phosphor film layer emits electroluminescent light.
