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 method of mounting screen material may include a screen mounted to a frame at multiple mounting points. One embodiment may include mounting patches attached along the perimeter of the screen. These mounting patches may be strain relieved in order to enable rolling the screen without sacrificing the in-plane rigidity of the patches when the screen is mounted to a frame. Stated differently, the strain relieved patches may reduce the strain on the screen in the circumstance the screen is rolled onto a core. The mounting patches may be strain relieved by locating notches or slits in the mounting patch.

Abstract: A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. Several modes of operation may be provided including an advanced 2D mode, and an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters. Another embodiment may be an optical structure for a multi-functional LCD display with wide color gamut and high stereo contrast. The optical structure may also be used to produce more saturated colors for a wider display color gamut and also may be used to produce a brighter backlight structure through light recycling of the wider bandwidth light back into the optical structure.

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 from 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: The present invention is a method of processing a sequence of frames from digital motion picture cameras to allow remapping of the time-base of the input frames to a new and possibly variable time-base in the output frame sequence. This invention provides a method that makes small adjustments to the user's specified positions to achieve optimal integer mapping from input frames to output frames in the integrated function. The present invention provides for an algorithm for frame rate resampling providing a method for determining the mapping of input frames to output frames and a method for smoothly ramping the mapping of input frames to output frames based on interactive user input and a method for optimizing the alignment of input frames to output frames such that during areas of constant speed the alignment is optimally centered on the frames and a method for computing the weighting function for averaging input frames to output frames and a method for handling negative values in the weighting function in regions of bright highlights.

Abstract: Disclosed is an apparatus and method of tiling and stitching together multi-projector images. The projection system enhances brightness, enables polarization based stereoscopic imagery and matches brightness for all viewers that view the images from the projection system. The projection system includes two or more projectors and projects two dimension and three dimensional images onto projection screens, such as gain screens.

Abstract: 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.

Abstract: Disclosed embodiments include stereoscopic systems having at least one compensator operable to reduce the sensitivity of polarization control over incidence angle of image source optics and analyzer optics. In an exemplary embodiment, the disclosed compensator is operable to compensate polarization changes induced by optics at either or both the image source subsystem and the analyzer subsystem, in which the polarization changes would be operable to cause leakage at the analyzer subsystem if uncompensated. As such, the disclosed compensators and compensation techniques are operable to reduce leakage at the analyzer subsystem even if the disclosed compensator may be located at the analyzer subsystem.
