An embedded light source is formed on the driver pad array in an emitter material layer, and the embedded light source emits light in a first color. A conductive material layer over the embedded light source forms a p-n junction between the emitter material layer and the conductive material layer. A color conversion layer can then convert a portion of the first color to at least a second color. Further, micro lens optics can be implemented to direct the light that is emitted through the color conversion layer.Type: ApplicationFiled: February 15, 2012Publication date: August 15, 2013Inventors: Rod G. Fleck, David D. Bohn, Andreas G. Nowatzyk
