Abstract

Image projection utilizing light-emitting diodes on a silicon (LEDoS) substrate is described herein. LEDoS devices selectively activate LED pixels to produce light. Light can excite color conversion materials of the LEDoS devices to form color images. Images can be projected onto a projection surface.
