ABSTRACT:
The present invention provides a face emission printing system including an array of face emission electroluminescent devices coupled to an optical structure. The face emission EL printhead is comprised of a substrate; and a plurality of layer stack supported on the substrate, each of the layer stack including a thin film active layer which generates light in response to conduction of electrical current, a first thin film electrode layer and a second thin film electrode layer, where at least one of said electrode layers being spaced apart from said active layer by a thin film dielectric layer. The first thin film electrode layer is transparent and light is emitted through the surface of the first thin film electrode layer. The layer stacks are preferably staggered and the optical structure is preferably a micro lens are optical concentrator formed integral to the emitting surface of the plurality of layer stacks.
