    Abstract: A directional display may include a waveguide. The waveguide may include light extraction features arranged to direct light from an array of light sources by total internal reflection to an array of viewing windows and a reflector arranged to direct light from the waveguide by transmission through extraction features of the waveguide to the same array of viewing windows. A further spatially multiplexed display device comprising a spatial light modulator and parallax element is arranged to cooperate with the illumination from the waveguide. An efficient and bright autostereoscopic display system with low cross talk and high resolution can be achieved.

    Abstract: A spatially multiplexed autostereoscopic display is arranged to provide landscape and portrait operation. Multiple optical windows may be provided by spatial and temporal multiplexing techniques. A fast response lens array pair is aligned with a fast response spatial light modulator, and synchronized to provide first and second sets of images with first and second respective directionalities to provide first and second sets of respective optical windows. The first and second sets of optical windows may each comprise two or more optical windows in each viewing lobe. The optical windows may be arranged with an inclination to the vertical of 25 degrees to 65 degrees. An observer tracking system may be arranged to direct left and right eye image data to the left and right eyes of an observer, respectively, for landscape and portrait orientations of the display.

    Abstract: Disclosed is a light guiding valve apparatus including a light valve, a two dimensional light emitting element array and an input side arranged to reduce light reflection for providing large area directional illumination from localized light emitting elements with low cross talk. A waveguide includes a stepped structure, in which the steps may include extraction features hidden to guided light propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Stray light falling onto a light input side of the waveguide is at least partially absorbed.

    Abstract: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources and hence defines the relative positions of system elements and ray paths. Lateral non-uniformities of output image are improved by means of adjustment of input aperture shape and reflective aperture shape. Cross talk in autostereoscopic and privacy displays may further be improved by light blocking layers arranged on the input end of the waveguide.

    Abstract: A directional backlight may include a light guiding apparatus including at least one transparent optical waveguide for providing large area collimated illumination from localized light sources. The waveguide is arranged in a first part and a second part with a light injection aperture between the respective parts.
