Patent number: 8704733Abstract: A method and system for use in conjunction with a push-pull liquid crystal modulator system for creating circularly polarized light of alternating handedness is provided. The method and system comprise a pair of surface mode liquid crystal cells and a driver electrically coupled to the cells. The driver is configured to move an electrical charge using a quenching pulse comprising a relatively brief voltage spike at a beginning of a waveform period. Multiple additional improvements are provided, including reducing the thickness of the LC gap (the distance between cell electrode plates), creating a charge connection or wiring connection to the cell electrodes, employing anti-reflection coating technology, thinner ITO and ITO index matched to the LC material, bonding all possible air to material surfaces, using superior glass, employing more efficient polarizers, and reducing projector blanking time.Type: GrantFiled: June 11, 2012Date of Patent: April 22, 2014Assignee: RealD Inc.Inventors: Matt Cowan, Josh Greer, Lenny Lipton, Joseph Chiu

Patent number: 8692738Abstract: An apparatus for displaying virtual objects within a physical set or scene. The apparatus includes a set assembly including at least one physical object, e.g., a background prop. A virtual object display assembly is provided with: a display element with a screen operable to display an image of an object; a beam splitter positioned at an angle between the screen and the set assembly; and a mask display element positioned within the set assembly at an image plane associated with the displayed image. The mask display element operates, when the display element operates to display the displayed image, to display a mask corresponding to the displayed image. The beam splitter is transmissive and reflective of light. The mask display element is positioned between the beam splitter and the physical object, and the displayed mask occludes a portion of the physical object and casts a shadow within the set assembly.Type: GrantFiled: June 10, 2011Date of Patent: April 8, 2014Assignee: Disney Enterprises, Inc.Inventors: Quinn Smithwick, Lanny S. Smoot, Daniel Reetz

Publication number: 20140062839Abstract: The general field of the invention is that of hybrid viewing devices comprising several screens of different nature. The device according to the invention comprises a stack comprising three superimposed viewing screens of the same dimensions and means for generating and processing images, the first viewing screen being a transparent emissive matrix screen, the second viewing screen being a matrix screen with controlled transparency, the third viewing screen being a transparent emissive matrix screen, the second viewing screen being disposed between the first viewing screen and the third viewing screen so as to be able to block all or part of the image displayed by the first viewing screen and/or the third viewing screen, the stack of three screens thus being arranged so as to be able to display an image on its first face and an image on its second face, the two images being able to be identical.Type: ApplicationFiled: August 30, 2013Publication date: March 6, 2014Inventors: Johanna DOMINICI, Sebastian Ellero, Laurent Laluque

Patent number: 8651684Abstract: A rear parallax emitter is disclosed for use, for example, in a display. The display includes a light modulator as well as the rear parallax emitter. The light modulator comprises a plurality of pixels viewable at a viewing position. The rear parallax emitter comprises a plurality of sets of light emitting regions (LERs) and has an area substantially coextensive with the light modulator and spaced a prescribed uniform distance from the display opposite from a viewing position. Each set of LERs is independently controllable to transmit a light color that differs from a light color transmitted by another set of LERs.Type: GrantFiled: July 28, 2011Date of Patent: February 18, 2014Assignee: UniPixel Displays, Inc.Inventor: Michael Mehrle
