Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

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: Display devices with high dynamic ranges approaching the limitations of the human eye are discussed herein. High dynamic range projections systems may be 2D or 3D and devices may or may not be implemented with polarization preserving optics for high efficiency. In one embodiment, 2D HDR projection systems may compensate the modulator for varying transmission and contrast versus field of view. In another embodiment, 3D HDR projection systems may include a global or pixelated/segmented modulator. The global or pixelated/segmented modulator may be included in a stereoscopic polarization switch or in a polarization-preserving stereoscopic projection system. Additionally, a combination of global/global or pixelated/pixelated, or global/pixelated modulators may be used.

Abstract: Disclosed is a light guiding valve apparatus comprising an optical valve, a two dimensional light source array and a focusing optic for providing large area collimated illumination from localized light sources. A stepped waveguide may be a stepped structure, in which the steps may be 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. A two dimensional array of viewing windows may be produced. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays with wide viewing freedom and low cross talk and near-eye displays that are substantially transparent.

Abstract: A front projection screen is provided having a first portion of material and a second portion of material. The first and second portions of material may have an undercut edge profile, and the first and second portions of material may be perforated, such that the perforations allow the first and second portions of material to be at least somewhat acoustically transmissive while substantially maintaining optical efficiency from the front side of the front projection screen. Such optical efficiency has particular utility in stereoscopic projection applications utilizing polarized encoded light.

Abstract: A dynamic iris is located on the imaging path of an optical lens system that includes a relay lens system and at least one projection lens system. A dynamic iris modulates image frames in an image data stream, resulting in a reduction in light transmission associated with the modulated image frames. A dynamic iris may be configured to change the size of its aperture as fast as or faster than the image frame period of the image data stream, and may be located at or near the pupil of a relay lens system, a projection lens system, or both. A second dynamic iris in the imaging path further modulates the image frames, resulting in a further reduction in light transmission. A dynamic iris may modulate an image frame based on an electronic preview of the image frame or based on metadata associated with the image frame.

Abstract: Curved polarization filters and methods of manufacturing such filters are described in the present disclosure. An exemplary method includes laminating a planar polarization layer to a planar retarder layer at a predetermined orientation and bending the laminate to create a curved filter. The strain on the retarder layer results in stress-induced birefringence, and the predetermined orientation of the retarder substantially compensates for the stress-induced birefringence. In some embodiments, the predetermination is based on mathematical models. In some other embodiment, the predetermination is based on experimental data.
