Patent number: 8162524Abstract: A light mixing system includes a transparent waveguide having a reflectorized edge, a light input edge and a light output edge opposite the reflectorized edge. The light input edge receives light of different colors from two or more light sources. The received light of different colors is totally internally reflected from opposite major surfaces of the waveguide. Formed inside the waveguide are a plurality of cavities bounded by walls substantially parallel to the edges and substantially orthogonal to the major surfaces of the waveguide. Interaction of the received light of different colors with one or more of the cavities and the reflectorized edge mixes the light of different colors before exiting the light output edge.Type: GrantFiled: July 20, 2011Date of Patent: April 24, 2012Assignee: Rambus Inc.Inventors: Daniel K.

Patent number: 7450799Abstract: Enhancement of the contrast ratio of optical flat panel displays by integrating an array of corner-cube retroreflectors into the front face of the optical display, said integration involving mutual adaptation of both the display and the corner-cube retroreflector geometry to unite the two disparate optical systems. The light emission from the display passes through the truncated vertex of the corner-cubes to the observer. The display directs its emitted light through the vertex apertures (either as a natural behavior, or by interposing a registered array of light concentrators between the display and the corner-cube array). The improvement in contrast ratio arises due to the corner-cube retroreflectors' ability to direct incident ambient light directly back to its source, rather than the viewer's eyes. Ambient light reflections are not attenuated but maximized; this maximization is directed away from the viewer, causing the array to appear dark even in direct sunlight.Type: GrantFiled: June 20, 2007Date of Patent: November 11, 2008Assignee: Uni-Pixel Displays, Inc.Inventors: Martin G. Selbrede, Garth Gobeli, B. Tod Cox, Daniel K. Van Ostrand, Martin A. Kykta

Publication number: 20080062161Abstract: A method includes obtaining a measurement of a property of a light source, scanning light from the light source onto a surface, such that the light interacts with the surface, detecting light from the surface to create a picture element, and correcting the picture element with the measurement of the property. An apparatus includes a scanned beam display, the scanned beam display is configured to receive a signal and to scan the signal for viewing by a user. The signal is to contain picture element information. The picture element information includes information for a plurality of colors, wherein information for at least one color is corrected to substantially remove a perturbation to the picture element information, such that an image containing the picture element information will be substantially unchanged by the perturbation.Type: ApplicationFiled: July 19, 2007Publication date: March 13, 2008Applicant: Microvision, Inc.Inventors: Margaret Brown, Voytek Andron, David Skurnik, Eric Altendorf, Martin Kykta, Mark Holton, Clarence Tegreene, Christopher Wiklof
