Abstract: A multiview backlight includes a first array active emitters configured to provide a first plurality of directional light beams and a second array of active emitters configured to provide a second plurality of directional light beams. The second array of active emitters is interleaved between active emitters of the first array of active emitters. Further, directional light beams of each of the first and second directional light beam pluralities have directions corresponding to view directions of a multiview display. A multiview display further includes an array of light valves configured to modulate the directional light beams to display a multiview image. An image resolution of the multiview image is configured to be dynamically selectable according to operational mode.

Abstract: A multiview backlight and mode-switchable backlight employ a planar backlight to emit scattered light and light-blocking layer having a plurality of apertures to provide a plurality of directional light beams from the scattered light. The mode-switchable backlight further includes another planar backlight configured to provide diffuse light in a two-dimensional (2D) operational mode, the plurality of directional light beams being provided in a three-dimensional (3D) mode. A 2D/3D mode-switchable display includes the mode-switchable backlight and a light valve array. A method of backlight operation includes directing scattered light from a planar backlight toward a light-blocking layer having a plurality of apertures and providing a plurality of directional light beams using an aperture of the aperture plurality.

Abstract: A multilayer static multiview display and method of multilayer multiview display operation provide a plurality of multiview images using diffractive scattering of light from guided light beams having different radial directions. The static multiview display includes a first multiview display layer configured to emit directional light beams representing a first multiview image by diffractive scattering light from a radial pattern of guided light beams within the first multiview display layer. The static multiview display further includes a second multiview display layer configured to emit directional light beams representing a second static multiview image by diffractive scattering light from a radial pattern of guided light beams within the second multiview display layer. The provided plurality of multiview images may include a composite color multiview image, a static multiview image, or an animated or quasi-static multiview image.

Abstract: Multiview backlighting having a color-tailored emission pattern provides directional light beams corresponding to a plurality of different views of a multiview image. A multiview backlight includes a light guide configured to guide light as guided light and a color-tailored multibeam element. The color-tailored multibeam element is configured to provide emitted light having the color-tailored emission pattern from the guided light. The emitted light includes a plurality of directional light beams having different principal angular directions corresponding to respective different view directions of a multiview display. The color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display.

Abstract: Multiview displays include a backlight and a screen used to form a plurality of multiview pixels. Each multiview pixel includes a plurality of sets of light valves. The backlight includes a light source optically coupled to a plate light guide configured with a plurality of multibeam elements. Each multibeam element corresponds to a set of light valves and is spatially offset with respect to a center of the set of light valves toward a center of the multiview pixel. The plurality of multibeam elements are also configured to couple out light from the plate light guide with different angles and angular offsets such that at least a portion of the coupled-out light beams interleave and propagate in different view directions of the multiview display.
