The keeper's note
A multi-planar plenoptic display combining several light-emitting and light-modulating planes for a novel glasses-free 3D display.
Abstract
A multi-planar plenoptic display assembly is provided that includes multiple spatially-varying light emitting and light modulating planes. The display assembly includes at least one light emitting device and may include, but does not require, a modulating device used in conjunction accordingto display methods taught herein to display light field data. A display assembly controller may be used to render a light field with depth into a multi-planar plenoptic display assembly by assigning decomposed portions of the light field to the display assembly for display or presentation by differing ones of the emitting elements and by operating a modulating device to provide a parallax barrier. In one embodiment, a dynamic parallax barrier and a number of bi-state screens. Another embodiment uses a beam splitter to co-locate two pairs of autostereoscopic displays each including a projector projecting 3D content, a parallax barrier, and an emissive/projector element.
