Abstract: Eletroluminescent elements with doubled-sided luminous surface and feasible processes for making such elements are disclosed. Double-sided illuminating EL lamps comprise a common layer in the preferred multilayer structure are proposed, and the use of common layer in such double-sided illuminating EL lamps have the advantages of fewer layers, smaller thickness, less weights, fewer manufacturing steps and less cost without sacrificing any functional feature or performance. Such double-sided illuminating EL lamps may be fabricated by paste-coating or ink-printing method with a sequential-process or split-process, and these EL lamps provide two illuminating surfaces that can emit light simultaneously or independently depending on the design of EL structure and driver's circuit.
