Multi-layer plenoptic displays that combine multiple emissive and light modulating planes

摘要

A multi-planar plenoptic display assembly with multiple spatially-varying light emitting and modulating planes. The display assembly includes at least one light emitting device and may include a modulating device used in conjunction according to 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 projector is used with bi-state screens. In another embodiment, two automultiscopic displays (either parallax barrier or lenticular lenses) are overlaid with a beam splitter. In a further embodiment, an oscillating mirror is used to temporally and optically move one automultiscopic layer (either parallax barrier or lenses) through space.

主权项

1. An automultiscopic display apparatus, comprising:
a first parallax barrier or lens system selectively operable to display parallax barrier patterns; a first planar emitting device selectively operable to emit light to the first parallax barrier or lens system; a second parallax barrier or lens system selectively operable to display parallax barrier patterns; a second planar emitting device selectively operable to emit light to the second parallax barrier or lens system; a beam splitter positioned between the first and second parallax barrier or lens systems to receive output light from the first and second parallax barrier or lens systems on first and second surfaces of the beam splitter, respectively; and a controller operating the first planar emitting devices to display a first component of a light field and the second planar emitting device to display a second component of the light field, wherein the first parallax barrier or lens system is spaced apart from the first surface of the beam splitter a first distance and the second parallax barrier or lens system is spaced apart from the second surface of the beam splitter a second distance greater than the first distance, whereby the first and second components are displayed in spaced apart planes.
