ABSTRACT:
A thin film electroluminescent edge emitter structure includes a common electrode layer and control electrodes disposed above the common electrode layer. At least one dielectric layer is disposed between the common electrode layer and control electrodes, and a phosphor layer is interposed between the one dielectric layer and common electrode layer. The common electrode layer, one dielectric layer and the phosphor layer define the light-emitting pixels of the emitter structure. Each pixel has a light-emitting face formed thereon and is operable upon application of electrical excitation to cause the radiation of light energy within its phosphor layer at least in a direction towards the pixel light-emitting face. An optical lens system associated with the pixels includes a preselected contour shaped on the light-emitting face of each pixel to define an optical lens integral therewith to project the light energy passed therethrough in a preselected direction and form a beam of light energy having a preselected beam pattern. A multi-color light emission system employed by the pixels includes a plurality of phosphor zones comprising the phosphor layer and capable of projecting different light energy through the light-emitting faces of the pixels. Also, separate edge emitter structures projecting different colors of light can be utilized in a electrophotographic printer.
