    Abstract: Disclosed is an imaging directional backlight including an array of light sources, and a control system arranged to provide variable distribution of luminous fluxes, scaled inversely by the width associated with the respective light sources in the lateral direction, across the array of light sources. The luminous intensity distribution of output optical windows may be controlled to provide desirable luminance distributions in the window plane of an autostereoscopic display, a directional display operating in wide angle 2D mode, privacy mode and low power consumption mode. Image quality may be improved and power consumption reduced.

    Abstract: Disclosed is an imaging directional backlight that cooperates with a spatial light modulator to direct light into a first viewing window for one set of image pixels and into a second viewing window for a second set of image pixels. The waveguide may comprise a stepped structure, where the steps further comprise extraction features 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. Such an apparatus may be used to achieve an autostereoscopic display with a flat structure, not requiring fast response speed spatial light modulators.

    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 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.

    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 screen repair patch and a screen flaw repair method. The screen repair patch includes an optical layer, a substrate layer, and an adhesion layer. The optical layer and a screen to be repaired have the same or similar optical performance. The substrate layer has a thickness of 10 to 250 microns. The adhesion layer has a thickness of 5 to 200 microns. In the screen flaw repair method, a repair patch is cut off from a region on a patch sheet corresponding to the position of a flaw of a screen, and the repair patch is attached to the corresponding position of the flaw of the screen by using a joining direction of the screen as an affixing direction of the repair patch. The screen repair patch and the screen flaw repair method of the present disclosure uses a patch that can be easily affixed and removed and can repair a flaw on site to maintain original optical efficiency and uniformity of a screen and are applied to a polarization-preserving screen to maintain high polarization contrast, so as to extend the service life of the screen.
