A process for producing a conformal electroluminescent system. An electrically conductive base backplane film layer is applied upon a substrate. A dielectric film layer is applied upon the backplane film layer, then a phosphor film layer is applied upon the dielectric film layer. An electrode film layer is applied upon the phosphor film layer using a substantially transparent, electrically conductive material. An electrically conductive bus bar may be applied upon the electrode film layer. Preferably, the backplane film layer, dielectric film layer, phosphor film layer, electrode film layer and bus bar are aqueous-based and are applied by spray conformal coating. The electroluminescent phosphor is excitable by an electrical field established across the phosphor film layer such that the device emits electroluminescent light upon application of an electrical charge between the backplane film layer and at least one of the electrode film layer and the bus bar. |
