Abstract
A direct projection light field display comprising an array of projectors for direct projection of a light field. The overall design and incorporation of additional optics achieve the optimal light distribution and small pixel size to produce a high definition, 3D display. The architecture of the direct projection light field display has low a brightness requirement for each projector, resulting in an increased projector density, decreased system, and a decreased power requirement, while producing a high-definition light field.
