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.
Claims17
A light field display comprising:
- an array of light projectors, each projector emitting light from a pixel along a ray path;
- a first lens system comprising:
- a first lens subsystem comprising a collimating array;
- and
- a second lens subsystem comprising a diffusing array, and
- a second lens system comprising a display lens,
- wherein light output from the display lens forms the light field.
