Patent number: 8944604Abstract: A method is provided for projecting a three-dimensional image. The system includes a first light source, the first light source emitting light in a first direction and a second light source emitting light in a second direction. A beam splitter device is disposed adjacent each light source and an imaging device is disposed adjacent the beam splitter device. Light from the first light source and the second light source travel a common optical path to a projector lens assembly.Type: GrantFiled: November 9, 2012Date of Patent: February 3, 2015Assignee: International Business Machines CorporationInventor: Casimer M.

Patent number: 8941918Abstract: The 3D image display device disclosed herein includes an image display panel outputting image signals; and a parallax barrier arranged in front of the panel, being spaced at a particular distance, and having a plurality of transparent portions. The transparent portions of the barrier have a plurality of transverse lines, each of which forms one cycle, and the transparent portions that are adjacent to each other in the longitudinal direction in one cycle are arranged to emit images to different fields of view, respectively. The panel operates on and off by lines in the transverse direction based on views.Type: GrantFiled: December 14, 2009Date of Patent: January 27, 2015Assignee: Korea Institute of Science and TechnologyInventors: Sung Kyu Kim, Seon Kyu Yoon

Patent number: 8942427Abstract: A three-dimensional (3D) image display device may display a perceived 3D image. A location tracking unit may determine a viewing distance from a screen to a viewer. An image processing unit may calculate a 3D image pixel period based on the determined viewing distance, may determine a color of at least one of pixels and sub-pixels displaying the 3D image based on the calculated 3D image pixel period, and may control the 3D image to be displayed based on the determined color.Type: GrantFiled: July 25, 2011Date of Patent: January 27, 2015Assignee: LG Electronics Inc.Inventors: Dongha Lee, Taesoo Park, Dongman Jeong, Kyoungll Lee

Publication number: 20150015815Abstract: A stereo picture display apparatus with decreased cross talk without a decrease in an aperture ratio, includes a picture displaying panel and a patterned retardation plate disposed on a viewer side of a picture displaying panel which includes left eye pixels and right eye pixels which are alternatively disposed at an integer of 2 or more, and black matrices; the patterned retardation plate includes a support and a patterned optically anisotropic layer thereon, having a first and second retardation region, and a boundary, the first and second retardation regions being alternately disposed at a predetermined pitch width in stripe pattern. The first and second retardation regions are different in at least one of an in-plane slow axis direction and a retardation from each other. The black matrices disposed at a position corresponding to the boundary have a larger width than a width of the black matrices not disposed thereat.Type: ApplicationFiled: October 1, 2014Publication date: January 15, 2015Applicant: FUJIFILM CORPORATIONInventor: Naoyoshi YAMADA

Publication number: 20150009561Abstract: A system for stereoscopic visualization of image information includes a display device defining a display area for displaying a left and a right partial image. The display device displays the left partial image to a left eye of an observer focused on the display area in a first viewing direction using a left observation beam path and the right partial image to the right eye in a second viewing direction using a right observation beam path. The system includes a vision assist through which the left and right observation beam paths pass. The vision assist sets a beam course for the left and right viewing observation beam paths wherein, starting from the left and right eyes in a direction toward the display area, a perpendicular distance between the left and right observation beam paths decreases to a minimum at a finite distance from the display surface.Type: ApplicationFiled: September 24, 2014Publication date: January 8, 2015Inventors: Peter Pacher, Rainer Sessner
