Abstract

In embodiments of imaging structure emitter configurations, 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. The embedded light sources are configured in multiple rows for scanning by an imaging unit to generate a scanned image for display.
