Patent number: 9733427Abstract: A method for manufacturing a display includes providing a plurality of light guiding fibers or other elements extending out from a display screen. The light guiding elements are in a matrix to form a first light guiding body forming a strip along the edges of each individual display screen. The first light guiding bodies form a compensating portion of an image compensating apparatus, a cross-sectional area of each light guiding element increasing from light-collecting end (closest to the display screen) to opposite light-releasing end. The compensating portion includes a light incident surface and a light emitting surface.Type: GrantFiled: October 14, 2016Date of Patent: August 15, 2017Assignee: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: I-Wei Wu

Patent number: 9535217Abstract: Multimode beam combiners include at least one gradient-step index optical fiber in which a refractive index difference at a core/cladding interface is selected to provide a numerical aperture so as to provide stable, uniform beam output. One or more such fibers is formed into a tapered bundle than can be shaped to provide a selected illuminated aperture. The fibers in the bundle can be separated by respective tapered claddings so as to be optically coupled or uncoupled. Illumination systems can include a plurality of such fibers coupled to a plurality of laser diodes or other light sources.Type: GrantFiled: May 1, 2015Date of Patent: January 3, 2017Assignee: nLIGHT, Inc.Inventors: Jason N. Farmer, Ronii C. Mehl, Robert G. Waarts

Patent number: 9519153Abstract: Disclosed is an optical valve or light valve for providing large area collimated illumination from localized light sources, and system and method thereof for 2D, 3D, and/or autosteroscopic displays. An optical valve may include a stepped structure, in which the steps include separated extraction features which may be optically hidden to light propagating in a first direction. Light propagating in a second direction may be refracted, diffracted, or reflected by the features to provide illumination beams exiting from the top surface of the optical valve. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays as well as improved 2D display functionality.Type: GrantFiled: November 18, 2011Date of Patent: December 13, 2016Assignee: RealD Inc.Inventors: Michael G. Robinson, Graham John Woodgate, Jonathan Harrold

Patent number: 9494733Abstract: An apparatus for compensating an image of a display includes a light incident surface, a light emitting surface, and a plurality of light guiding channels. An area of the light emitting surface is greater than an area of the light incident surface. The plurality of light guiding channels are independent from each other, each light guiding channel extends from the light incident surface to the light emitting surface. A cross section area of the light guiding channel increases along a direction from the first light incident surface to the first light emitting surface. Light from the light incident surface is extended to the light emitting surface by the light guiding channels. The present invention further discloses a method for manufacturing the same.Type: GrantFiled: January 25, 2014Date of Patent: November 15, 2016Assignee: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: I-Wei Wu
