Abstract: Chemically-welded optical devices and associated methods for chemically welding optical devices are disclosed herein. Such optical devices may be used in display systems, and may include subcomponents comprising one or more optical films employed for polarization manipulation, as well as a substrate for protecting the optical film(s). An optical film may be chemically welded directly to the substrate using a solvent, and any additional optical films may be chemically welded to a prior optical film previously welded to the substrate. The chemical welding process of the present disclosure may include applying the solvent on the optical film in order to partially dissolve the surface of the optical film prior to adhesion to the substrate. Macromolecules on the dissolved surface of the optical film may be in a loosened state and may be realigned when the solvent evaporates.

Abstract: A method and system for presenting both autostereoscopic images and planar images in a single display is disclosed. The design comprises processing the planar images received in the form of planar image data. The processing comprises at least one from a group comprising selectively employing bleed-through processing to enhance the planar image data when viewed through a lens sheet comprising slanted lenticules, selectively introducing blurring into the planar image data, and selectively employing anti-alias processing to the planar image data. Certain super pixels may be computed that differ from standard pixels, and lenticules in the data sheet may be slanted at desired angles. The physical lenticules may cause bleed-through that may be processed. Resolution may be computed after processing, and the resolution implemented for display. Mode switching between planar and autostereoscopic imaging may be provided in the form of Metadata or visible flags.

Abstract: A polarizing beam splitter assembly for directing image light on an input path into multiple exit light paths comprises multiple prisms with edges that meet to form a seam. The polarizing beam splitter assembly includes a diffracting element prior to the seam in the input light path. The diffracting element comprises a geometry that performs at least one of blocking a portion of the image light and scattering a portion of the image light.

Abstract: A 3D image pixel in a spatially multiplexed stereo 3D display includes a first left-eye subpixel and a second left-eye subpixel that are both driven when displaying the left-eye image. The 3D image pixel also includes a first right-eye subpixel and a second right-eye subpixel that are both driven when displaying the right-eye image. The subpixels may all have a square shape. Single color emitters in the subpixels of the same eye may be driven by the same electronics. A 3D image pixel in a second spatially multiplexed stereo 3D display includes a left-eye pixel driven when displaying the left-eye image and a right-eye pixel driven when displaying the right-eye image. The pixels may all have a rectangular shape, and the horizontal measurement of the pixels may be greater than the vertical measurement of the pixels.

Abstract: A polarization conversion system separates light from an unpolarized image source into a first state of polarization (SOP) and an orthogonal second SOP, and directs the polarized light on first and second light paths. The SOP of light on only one of the light paths is transformed to an orthogonal state such that both light paths have the same SOP. A polarization modulator temporally modulates the light on the first and second light paths to first and second output states of polarization. First and second projection lenses direct light on the first and second light paths toward a projection screen to form substantially overlapping polarization encoded images. The polarization modulator may be located before or after the projection lenses. The polarization-encoded images may be viewed using eyewear with appropriate polarization filters.

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 deflected 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 from the side of the waveguide and hence defines the relative positions of system elements and ray paths. A directional backlight with small footprint and low thickness may be provided.
