    摘要: An electrical connection assembly for a directional display comprising a directional backlight may include stack of flat connectors and a strip comprising an end portion with an array of light sources and a base portion with an array of connectors. The end portion and base portion may be shaped so that the base portion extends outwardly from the end portion. Light sources of the directional display may be individually addressable by means of a highly compact arrangement of connections, achieving low thickness and small bezel width.

    摘要: 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.

    摘要: Disclosed is an optical inline light guiding apparatus which may include a substantially parallel planar light expansion section and a light extraction section comprising a stepped structure, in which the steps may be extraction features and guiding features. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays with wide viewing freedom, high efficiency and low cross talk and other directional display uses.

    摘要: 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. In operation, luminance streaks and bright illumination regions may be formed due to undesirable imaging characteristics from the structure of the Fresnel mirror. Fresnel mirror draft facets and reflective facet microstructures are provided that achieve reduction of visibility of light streaks and bright illumination regions.
