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. The uncorrected system creates non-illuminated void portions when viewed off-axis preventing uniform wide angle 2D illumination modes. The system may be corrected to remove this non uniformity at wide angles through the introduction of additional sources away from the system's object plane, additional imaging surfaces, and/or by altering ray paths.

Abstract: Disclosed is a head-mounted single panel display system that uses one or more liquid crystal switches and a polarizing beam splitter to redirect images from a single microdisplay panel to the viewer's eyes. The light emanating from the display panel is first directed, using a polarizing beam splitter, into two near-identical optical imaging systems, each forming an image in the left and right eyes. For stereoscopic (3D) operation, the light is modulated such that an image is seen in only one eye at a time. By providing time sequential stereoscopic imagery at a frame rate greater than 50Hz in each eye, flicker free, full resolution 3D can be visualized.

Abstract: A method and apparatus for providing optimal correction to depth mapping between captured and displayed stereoscopic content. The solution is derived in a continuous form that can be implemented through CGI scaling techniques compatible with image rendering techniques. Similar correction can be implemented with variable depth-dependent camera separation and disparity re-mapping. The latter is applicable to correcting existing stereoscopic content.

Abstract: A system for stereoscopic display and a bendable polarization switch for use with a system for stereoscopic display provide alternately polarized left and right eye images. Viewers then wear polarization analyzing eyewear to correctly see the different images. More specifically, a bendable polarization switch may be laminated to the front of a system for stereoscopic display. The bendable polarization switch may be used with a modulator configuration that is compatible with various performance requirements in a manner that is a low-cost manufacturing friendly solution. Further, the bendable polarization switch is a robust polarization switch technology that is reliable in an environment where mechanical stresses are inevitably applied during product lifetime

Abstract: Disclosed embodiments relate to a stereoscopic projection system and methods. An exemplary disclosed projection system includes an optical component disposed between the lenses of a lens arrangement. An exemplary lens arrangement includes a first power group, a second power group, and an aperture stop. In an embodiment, the optical component is disposed between the first power group and the aperture stop. In an exemplary embodiment, the optical component is proximate to the aperture stop. By disposing the optical component closer to or proximate to the aperture stop in the lens arrangement, various benefits may be realized, including improved contrast uniformity.

Abstract: This disclosure describes stereoscopic flat panel display systems based on the polarization encoding of sequentially displayed left and right eye images. The systems comprise line-by-line addressed liquid crystal display (LCD) panels, illuminating back light units and polarization control panels (PCPs). Right and left eye images are written sequentially onto the LCD whose polarization is controlled by a substantially synchronously driven PCP. The backlight may be continuously illuminated, or modulated temporally, spatially or both, as can the PCP.

Abstract: This disclosure generally relates to stereoscopic images and stereoscopic video signals, and more specifically relates to encoding, distributing, and decoding stereoscopic images and stereoscopic video signals for use in television and high definition television systems, teleconferencing, picture phones, computer video transmission, digital cinema, as well as in other applications that include storage and/or transmission, over any suitable medium, of still or moving stereoscopic images, or combinations of moving and still stereoscopic images, in a form that is compatible with existing infrastructure, without requiring additional system functionality, while providing a means to allow higher resolution images to be distributed while maintaining compatibility with the existing infrastructure. The techniques hereof can be employed, for example, for distributing stereo 3D movies via optical disk, satellite, broadcast, cable, or internet, using current infrastructure, to consumers.

Abstract: Disclosed are various lenticular display systems that include either a color filter array (CFA) or a colored lens array that is spaced from the pixels of an underlying display panel. In an embodiment, the CFA of a lenticular display may be operable to provides a locally ‘static color’ reproduction of images as a function of viewing angle. It may also enable the resolution of the CFA to be relatively coarse. Both separating the CFA from the panel and reducing the resolution significantly may reduce the system cost and allow higher resolution to be realized.
