Patent number: 10712572Abstract: A light field camera capturing one or more light field frames including intensity and angle information of received light. The light field camera includes an array of pixels, a liquid crystal layer overlaying the array of pixels, and a controller. The controller controls, at each time instant, one or more voltages applied to the liquid crystal layer. The controller adjusts, based on the one or more voltages, the liquid crystal layer to control amounts of light at one or more angles transmitted through the liquid crystal layer and captured by the array of pixels as a light field frame. The controller can determine depth information based on the captured one or more light field frames.Type: GrantFiled: August 7, 2017Date of Patent: July 14, 2020Assignee: Facebook Technologies, LLCInventors: Xinqiao Liu, Yijing Fu, Lu Lu

Patent number: 10705383Abstract: An image display device includes a display panel, a plurality of light emitting elements, a reflective sheet, and a first optical sheet. The display panel displays an image on a front face of the display panel. The light emitting elements are disposed along one edge of the display panel. The reflective sheet is disposed opposite a rear face of the display panel. The reflective sheet reflects light from the light emitting elements toward the rear face of the display panel. The first optical sheet is disposed between the display panel and the reflective sheet. The first optical sheet has a plurality of protrusions on a face of the first optical sheet that is opposite the reflective sheet. The protrusions have ridgelines extending along a direction that is different from a direction in which the one edge of the display panel extends.Type: GrantFiled: April 26, 2019Date of Patent: July 7, 2020Assignee: FUNAI ELECTRIC CO., LTD.Inventor: Akihisa Ogawa

Patent number: 10670920Abstract: Unidirectional grating-based backlighting includes a light guide and a diffraction grating at a surface of the light guide. The light guide is to guide a light beam and the diffraction grating is configured to couple out a portion of the guided light beam using diffractive coupling and to direct the coupled-out portion away from the light guide as a primary light beam at a principal angular direction. The diffraction grating is to further produce a secondary light beam directed into the light guide at an opposite one of the principal angular direction. The unidirectional grating-based backlighting further includes an angularly selective reflective layer within the light guide adjacent to the light guide surface that is configured to reflectively redirect the diffractively produced, secondary light beam out of the light guide in the direction of the primary light beam.Type: GrantFiled: September 7, 2017Date of Patent: June 2, 2020Assignee: LEIA INC.Inventor: David A. Fattal
