Patent number: 11181731Abstract: Systems and methods are described for a wide field of view (WFOV) optical doublet system. The system includes a first lens. The first lens has a first surface facing a viewer side of the system and a second surface facing away from the viewer side. The first lens has a positive refractive power. The system includes a second lens. The second lens has a first surface facing the first lens and a second surface facing away from the first lens. The second lens has a positive refractive power. The system includes a display panel. The display panel has a display surface facing the second surface of the second lens. The first lens, the second lens, and the display panel are configured in order from the viewer side along an optical axis of the system. Only one surface of either the first lens or the second lens is a diffractive surface and only two surfaces are Fresnel surfaces.Type: GrantFiled: January 2, 2018Date of Patent: November 23, 2021Assignee: KOPIN CORPORATIONInventors: Rodney Bumgardner, Raymond T.

Patent number: 7242383Abstract: An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system that has a display computer that generates images to be displayed on the liquid crystal display and connected to the active matrix liquid crystal display. A data link transmits data at a rate of speed of greater than 200 Mbytes per second in series for at least a portion between the display computer and the active matrix liquid crystal display. In a preferred embodiment, the display system has a randomizing device that alternates the amplifier through which an analog video signal passes.Type: GrantFiled: May 10, 1999Date of Patent: July 10, 2007Assignee: Kopin CorporationInventors: Matthew Zavracky, Jeffrey Jacobsen, Frederick P. Herrmann, Wen-Foo Chern, Hiap L. Ong, John C. C. Fan, Bor-Yeu Tsaur, Alan Richard, Ronald P. Gale, Jason Lo, Stephen A. Pombo, Rodney Bumgardner

Publication number: 20070018919Abstract: An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system. The image is written to the the display therein causing the liquid crystal to move to a specific image position. A light source is flashed to illuminate the display. The pixel electrodes are set to a specific value to cause the liquid crystal to move towards a desired position. The process of writing, flashing, and setting the electrode intensity value to reorient the liquid crystal to produce an image is repeated.Type: ApplicationFiled: June 26, 2006Publication date: January 25, 2007Inventors: Matthew Zavracky, Frederick Herrmann, Wen-Foo Chern, Alan Richard, Ronald Gale, Jason Lo, David Ellertson, Kuojinng Tsai, John Fan, Bor-Yeu Tsaur, Stephen Pombo, Rodney Bumgardner, Duy-Phach Vu

Publication number: 20060168859Abstract: A binocular display device or module includes a pair of display panels that are custom aligned with respective viewing optics. The binocular display device has a first lens assembly for viewing the first display panel and a second lens assembly for viewing the second display panel. Alignment fixtures within the binocular display device are used to physically align and fix the optics with the display panels using an alignment system. The alignment system includes a camera system for viewing the first display panel of the binocular display device through the first lens assembly, and the second display panel through the second lens assembly. Display panel alignment indicia can be located on the first and second display panels. A viewing screen system can be included for viewing images of the display panel alignment indicia on the first and second display panels which are provided by the camera system.Type: ApplicationFiled: November 23, 2005Publication date: August 3, 2006Inventors: Stephen Pombo, Bor-Yeu Tsaur, Rodney Bumgardner

Publication number: 20050270437Abstract: Alignment of an imaging area of a display with a user's eye provides optimum image quality for the user. Typically, a display is formed of a display panel encased within a carrier. The carrier is used to mechanically align the display panel within a device housing. However, the display panel must first be aligned within the carrier and the carrier and display combination aligned within a device housing. By utilizing the display panel without the carrier, one alignment step is removed from the installation process. Placing the display panel within a housing having an alignment device ensures proper alignment of an imaging area of the display panel with an opening of the housing.Type: ApplicationFiled: July 21, 2005Publication date: December 8, 2005Inventors: Matthew Zavracky, Rodney Bumgardner, Lawrence Cuprys
