20130088487 | AUTOSTEREOSCOPIC DISPLAY WITH PLANAR PASS-THROUGH - A method and system for presenting both autostereoscopic images and planar images in a single display is disclosed. The design comprises processing the planar images received in the form of planar image data. The processing comprises at least one from a group comprising selectively employing bleed-through processing to enhance the planar image data when viewed through a lens sheet comprising slanted lenticules, selectively introducing blurring into the planar image data, and selectively employing anti-alias processing to the planar image data. Certain super pixels may be computed that differ from standard pixels, and lenticules in the data sheet may be slanted at desired angles. The physical lenticules may cause bleed-through that may be processed. Resolution may be computed after processing, and the resolution implemented for display. Mode switching between planar and autostereoscopic imaging may be provided in the form of Metadata or visible flags. | 04-11-2013 |
20130088655 | Stereoscopic display system with active switchable retarder - Disclosed herein are displays and related methods for providing stereoscopic imagery, wherein an air gap may be provided between components of the display to allow a reduction in the amount of bonding material used to bond a stereoscopic display panel with a polarization control panel (PCP) element comprising an active switchable retarder. In some embodiments, the PCP element is at least the size of the display panel such that the entirety of the display panel is covered by the PCP element, and thus there would be neither tight tolerance horizontal nor vertical alignment requirements between the PCP element and the display panel. Structural support of the components of the display may be provided by bonding around the edges of the rigid or semi-rigid stereoscopic display panel and PCP element. For example, the air gap may be created with uniform spacers between the stereoscopic display panel and the PCP element. | 04-11-2013 |
20130089744 | Chemically-welded optical devices - Chemically-welded optical devices and associated methods for chemically welding optical devices are disclosed herein. Such optical devices may be used in display systems, and may include subcomponents comprising one or more optical films employed for polarization manipulation, as well as a substrate for protecting the optical film(s). An optical film may be chemically welded directly to the substrate using a solvent, and any additional optical films may be chemically welded to a prior optical film previously welded to the substrate. The chemical welding process of the present disclosure may include applying the solvent on the optical film in order to partially dissolve the surface of the optical film prior to adhesion to the substrate. Macromolecules on the dissolved surface of the optical film may be in a loosened state and may be realigned when the solvent evaporates. | 04-11-2013 |
20130093646 | Electronic display tiling apparatus and propagation based method thereof - 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. | 04-18-2013 |
20130100414 | Waveplate compensation in projection polarization conversion systems - Three dimensional projection systems may be single projector or multiple projector systems. These 3D projection systems may include a one or more polarization conversion systems (PCS). Each PCS may be designed for relatively small throw ratios and thus, may be designed to accommodate the small throw ratios. Each PCS may include a polarizing beam splitter, a first optical stack, a reflector and a second quarter wave retarder. The first optical stack may include a rotator, a polarizer, a polarization switch and a first quarter wave retarder. Each PCS may receive light from a respective projector, and the PBS in each PCS may direct the light toward the first optical stacks. The light may be converted to a different polarization state as it passes through the first optical stack. The converted light may then be re-directed by a reflecting element to a second quarter wave retarder. The second quarter wave retarder may convert linearly polarized light to circularly polarized light. | 04-25-2013 |
20130113788 | Imaging path speckle mitigation - Disclosed herein are optical projection systems and related methods for projecting imagery employing shifting image position in-time to mitigate speckle. Exemplary optical systems may include a projector having a light source, a relay lens and at least one projection lens for projecting images. The relay lens or the projection lens may have at least one lens element that may be translated in-time substantially orthogonal to the optical axis of the optical system. Alternatively, the projection lens in its entirety may be shifted in-time to reduce speckle. Further, in stereoscopic embodiments, two projection lenses may be employed, wherein at least one element in each projection lens is moveable to shift the image in-time to reduce speckle. Moreover, electronic compensation, such as electronic addressing or image warping, for the image shifting may be employed to shift the image in a direction opposite to the speckle-reducing shift in position. | 05-09-2013 |
20130135589 | Laser beam scanned display apparatus and method thereof - Generally, near seamless electronics displays may be employed in cinema and exhibition applications. Laser scanned displays may be enabled such that the display may display three dimensional (“3D”) content. A first method to enable a laser scanned display for 3D content may employ polarization, with or without polarization conversion and another method may employ multiple colors. Additionally, the envelope function that may be employed across the display may be achieved by changing laser power as a beam is scanned on the screen or by changing the dwell time of the laser beam on the pixels. One method of minimizing the effects of seams in the screen may be to reduce the screen resolution near the seams by screen design and/or laser beam dwell time or illumination energy. | 05-30-2013 |
