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.

Abstract: An adaptive background multiview image display system and method provides improved multiview image quality. Systems and methods may involve generating crosstalk data that reduces crosstalk between a first view of subject image and a second view of the subject image. The subject image may be a multiview image to be overlaid on a background image. A crosstalk violation may be detected in the subject image based on the crosstalk data. At least one of a color value or a brightness value of the background image is determined according to a degree of the crosstalk violation to generate the background image. The subject image may then be overlaid on the generated background image.

Abstract: Multiview backlighting employs a plasmonic multibeam element having a color-tailored emission pattern to provide 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 plasmonic multibeam element. The plasmonic multibeam element includes a plasmonic material and is configured to provide emitted light having a 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 and the color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display.

Abstract: A bar collimator and a backlight system employ diffractive coupling to provide a collimated source of illumination to a backlight. The bar collimator includes a light guide and a diffraction grating disposed on a side of the light guide. The light guide is configured to guide light received from a light source as guided light. The diffraction grating is configured to diffractively couple out a portion of the guided light and to direct the diffractively coupled-out portion toward an input of a backlight as a collimated light having an extent corresponding to a length of the backlight input. A backlight system includes the bar collimator and further includes a light source and a backlight adjacent to the light guide of the bar collimator, the backlight being configured to receive collimated light from a diffraction grating of the bar collimator.

Abstract: A polarized backlight employs a light source configured to provide polarized light and a light guide to guide the polarized light. A polarization-preserving scattering feature optically coupled to the light guide is configured to scatter a portion of the guided polarized light out of the light guide as emitted polarized light. A polarization of the emitted polarized light is determined by a polarization of the guided polarized light.
