Patent number: 9446578Abstract: A method of flexographically printing a uniform pattern on a substrate where the ink deposited on the substrate is deposited in the intended location and not in unintended locations. A flexo-master comprises a pattern formed by a plurality of lines including at least one junction, and printing the pattern including the at least one junction in ink on a substrate forming a printed pattern, wherein the printed junction has a different shape than the at least one junction on the flexo-master. In addition to the junction formation, a discontinuous line on the flexo-master may be used to print a continuous line, a single line may be used to print two lines, and two or more lines may be used to print a single line. The flexo-master pattern lines may additionally have a fill pattern comprising various geometries that are used to uniformly print the pattern on the substrate.Type: GrantFiled: June 11, 2013Date of Patent: September 20, 2016Assignee: EASTMAN KODAK COMPANYInventors: Dan Van Ostrand, Kevin Derichs

Publication number: 20150023052Abstract: A multi-display system includes a single, two-sided backlight assembly between the display panels. The two-sided backlight assembly is able to emit light in two light paths generally 180 degrees apart—one light path passes through one of the display panels and another light pass through the other of the display panels. That is, the two-sided light guide assembly emits light out two sides and generally in opposite directions. The two-sided backlight assembly uses lights such as light emitting diodes (LEDs) mounted on the side of a light guide thereby permitting the backlight assembly to be relatively thin. Because a single, thin, two-sided backlight assembly is used, the overall depth of the multi-display system is less than would be the case if two separate backlight assemblies were used.Type: ApplicationFiled: July 18, 2013Publication date: January 22, 2015Inventor: Dan VAN OSTRAND

Publication number: 20090262129Abstract: In a display system, a color gamut of the displayed images is extended by adding one or more primary colors lying outside a tristimulus color space triangle to a Red, Green, Blue (RGB) system, modulating light emitted by both light sources lying inside the tristimulus color space triangle and light sources lying outside the tristimulus color space triangle, and adding a non-tristimulus vertex to construct an extended-gamut polygon. The display system adds one or more primary colors to the RGB system, which lie outside the tristimulus color space triangle but within a CIE (International Commission on Illumination) color space.Type: ApplicationFiled: April 9, 2009Publication date: October 22, 2009Applicant: Uni-Pixel Displays, Inc.Inventors: Martin G. Selbrede, Lynn Essman, Dan Van Ostrand

Publication number: 20090142020Abstract: The application of optical micro structures improve the quality of light available to the viewer of an optical display system, or any display which works on the concept of moving one surface into direct contact or close proximity of a light guide to extract light through frustrated total internal reflection. Certain ones of the microstructures can act to assist in overcoming suction between the surface and the light guide.Type: ApplicationFiled: December 30, 2008Publication date: June 4, 2009Applicant: Uni-Pixel Displays, Inc.Inventors: Dan Van Ostrand, Carey King, Garth Gobeli

Patent number: 7486854Abstract: The application of microstructures which improve the quality of light available to the viewer of an optical display system, or any display which works on the concept of moving one surface into direct contact or close proximity of a light guide to extract light through frustrated total internal reflection. Optical microstructures are introduced on one or both of the surfaces of the active layer to enhance its performance. Since the active layer has both an input and an output function, means for enhancing both are presented. The input function to the active layer occurs on the internal surface, so this is where the present invention adds a collector-coupler, a means for facilitating the migration of light from the waveguide into the active layer.Type: GrantFiled: January 24, 2006Date of Patent: February 3, 2009Assignee: Uni-Pixel Displays, Inc.Inventors: Dan Van Ostrand, Carey King, Garth Gobell

Patent number: 7449759Abstract: An electromechanical dynamic force profile articulating mechanism for recovering or emulating true parallel plate capacitor actuation behaviors from deformable membranes used in MEMS systems. The curved deformation of flexible membranes causes their MEMS behavior to deviate from known interactions between rigid plates that maintain geometric parallelism during ponderomotive actuation.Type: GrantFiled: August 30, 2005Date of Patent: November 11, 2008Assignee: Uni-Pixel Displays, Inc.Inventors: Martin G.

Patent number: 7042618Abstract: A circuit for implementing a registration-free, contiguous conductive plane. A circuit may include a plurality of conductive structures in a first plane. The circuit may further include a contiguous conductive equipotential surface in a second plane parallel to the first plane. The circuit may further include activation means configured to adjust an electric field between the first and second planes thereby activating one or more structures in the first plane by increasing a potential difference between the first and second planes to a threshold level deemed to constitute an active state. The circuit may further include deactivation means configured to adjust the electric field between the first and second planes thereby deactivating one or more structures in the first plane by decreasing the potential difference between the first and second planes below a threshold level deemed to constitute a deactivation state.Type: GrantFiled: February 26, 2003Date of Patent: May 9, 2006Assignee: Uni-Pixel Displays, Inc.Inventors: Martin G.
