    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.

  • Patent number: 10288253
    Abstract: This invention relates generally to a light panel light source shade in the form of a masking tape or sheet. Ideally the masks may be printed directly on a surface design layer for use with the light panel. The invention is for use in the field of decorative 5 lighting. The problem of the alternating bright and dark areas on an illuminated face of a pane of a light panel is that they produce an unpleasant mottled surface brightness around the perimeter or across a face of the pane of a light panel. A light pane light source shade is developed to produce a uniform intensity of light across the face of the light panel.
