Abstract
In embodiments of an imaging structure with embedded light sources, an imaging structure includes a silicon backplane with a driver pad array. The embedded light sources are formed on the driver pad array in an emitter material layer, and the embedded light sources can be individually controlled at the driver pad array to generate and emit light. A conductive material layer over the embedded light sources forms a p-n junction between the emitter material layer and the conductive material layer. Micro lens optics can be positioned over the conductive material layer to direct the light that is emitted from the embedded light sources. Further, the micro lens optics may be implemented as parabolic optics to concentrate the light that is emitted from the embedded light sources.
