Abstract
The present disclosure relates to a directional pixel for a high-angular resolution, wide field of view, multiple view display. The design teaches a directional pixel comprising a substrate, one or more pixel driving circuits, one or more nano- or micro-scale subpixels, and one or more directional optical guiding surfaces, wherein each of said one or more subpixels is comprised of a light emitting device emitting a light beam and an optical microcavity housing said light emitting device. The optical microcavity is comprised of a plurality of reflective surfaces to specifically manipulate and tune said light beam, wherein one or more of said reflective surfaces is a light propagating reflective surface which propagates said light beam out of said microcavity, and said light propagating reflective surface is connected to said one or more directional optical guiding surfaces to direct said light beam at a specific angle. A high-angular resolution, multiple-view light-field display is created by deploying a plurality of directional pixels into a directional pixel array system.
