Abstract: Disclosed is an imaging directional backlight polarization recovery apparatus including an imaging directional backlight with at least a polarization sensitive reflection component with optional polarization transformation and redirection elements. Viewing windows may be formed through imaging individual light sources and hence defines the relative positions of system elements and ray paths. The base imaging directional backlight systems provide substantially unpolarized light primarily for the illumination of liquid crystal displays (LCDs) resulting in at least 50% loss in light output when using a conventional sheet polarizer as input to the display. The invention herein introduces a polarization sensitive reflecting element to separate desired and undesired polarization states for the purposes of transformation and redirection of the reflected light for usable illumination. Polarization transformation and redirection can be provided by additional components such as retarder films and specular mirror surfaces.

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 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: Disclosed herein are techniques for the reduction speckle of a projection display system using novel lenslet integrators and related methods. In one embodiment, a lenslet integrator system for reducing speckle on a display screen may comprise a first lenslet array configured to receive incoming light for use in displaying an image on a display screen. Specifically, the first lenslet array has motion sufficient to reduce speckle by averaging multiple speckle patterns across its array. Such an exemplary system may also include a second lenslet array configured to receive light that is roughly focused from the moving first lenslet array, due to the motion of the first array. In addition, such systems may also include an output lens configured to receive light focused from the second lenslet array for output from the system for illumination of the display screen.

Abstract: Disclosed is a method and apparatus for substantially eliminating the appearance of seams between tiled panels of a display. Non-imaging magnification may be used to substantially eliminate the appearance of seams. Additionally, the appearance of seams between the tiled panels of a display may be substantially eliminated by employing propagation based elimination. The methods disclosed can be used to generate substantially seamless 2D and 3D displays. Additionally, a method and apparatus for achieving substantially uniform panel brightness and color correction may be addressed. The substantially seamless tiled displays may employ specific data formats for use in displaying images on the individual displays which may be tiled together to form a larger, substantially seamless tiled display and may employ other techniques not utilized in known video wall applications. These functions may include an intensity envelope in addition to substantially complying with the Digital Cinema Initiative (“DCI”) security concerns.

Abstract: A method for demultiplexing frames of compressed image data is provided. The image data includes a series of left compressed images and a series of right compressed images, the right compressed images and left compressed images compressed using a compression function. The method includes receiving the frames of compressed image data via a medium configured to transmit images in single frame format, and performing an expansion function on frames of compressed image data, the expansion function configured to select pixels from the series of left compressed images and series of right compressed images to produce replacement pixels to form a substantially decompressed set of stereo image pairs. Additionally, a system for receiving stereo pairs, multiplexing the stereo pairs for transmission across a medium including single frame formatting, and demultiplexing received data into altered stereo pairs is provided.

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.
