Patent number: 8947605Abstract: An autostereoscopic display in which image data, in the form of grey level information for red, green, and blue components of pixels in multiple images representing multiple perspective views of a scene, are recombined into a second set of images generally consisting of parts of all the original multiple perspective images, arranged within the second set of images in such a way that a 3D image is seen when the second set of images are displayed in sequence.Type: GrantFiled: May 25, 2012Date of Patent: February 3, 2015Assignee: Dimension Technologies, Inc.Inventor: Jesse B.

Publication number: 20150002767Abstract: An autostereoscopic display device produces 3D images for off-axis viewing. In some embodiments, the autostereoscopic display device includes a screen with a screen surface and a liquid crystal display parallel to and in front of the screen. Sets and subsets of thin parallel vertical light-emitting lines are displayed on the screen, with each subset capable of being independently turned on and off. The liquid crystal display includes pixel elements arranged into vertical columns. The light-emitting lines are located behind the pixel elements such that the eye of an observer sees all of one of the sets of thin parallel vertical light-emitting lines behind one of the sets of the vertical columns. The image displayed by the display device appears as a 3D image to the observer that adjusts as the observer's head changes positions.Type: ApplicationFiled: June 30, 2014Publication date: January 1, 2015Inventor: Jesse B. Eichenlaub

Patent number: 8355019Abstract: A 3D viewing system captures offset images from off-axis camera perspectives inclined to a normal of base plane of a scene that includes one or more objects projecting from the base plane. The offset images, which take a planar form, are displayed from a display surface at an off-axis viewing perspective that is inclined to a normal of the display surface similar to the inclination of the off-axis camera perspective to the normal of the base plane. The offset images undergo a distortion to counteract a keystone distortion associated with the off-axis viewing perspective. The base plane of the scene is oriented parallel to the display surface, and the objects projecting from the base plane appear to project from the display surface.Type: GrantFiled: November 2, 2007Date of Patent: January 15, 2013Assignee: Dimension Technologies, Inc.Inventor: Jesse B.

Patent number: 8189129Abstract: The backlight system of the invention creates illumination behind a liquid crystal or other transparent display. In one mode of operation it produces a series of precise, thin slanted lines with dark space in between which are used to make multiple perspective views, displayed simultaneously on the LCD, visible from a series of horizontally spaced viewing zones spaced in front of the display. In another mode of operation, it produces even diffuse illumination similar to that generated by conventional backlights, allowing the LCD to display conventional 2D images.Type: GrantFiled: November 6, 2009Date of Patent: May 29, 2012Assignee: Dimension Technologies, Inc.Inventor: Jesse B.

Patent number: 7417617Abstract: Images with enhanced resolution are created with a display device comprising a non-transmissive light valve including addressable pixels, a light source that directs light to the light valve, and a lens positioned between the light valve and the light source, the lens directing light from the light source to the pixels on the light valve and the light valve directing light to viewing optics. The light valve is an integrated circuit ferroelectric liquid crystal device (ICFLCD), or other light valve arrays such as a digital light processor (DLP) display, having an array of addressable pixels. Such light valves may be mounted in a head mounted display.Type: GrantFiled: April 26, 2004Date of Patent: August 26, 2008Assignee: Dimension Technologies, Inc.Inventor: Jesse B. Eichenlaub

Patent number: 6590605Abstract: An autostereoscopic display includes an image forming device and a substrate having alternating strips, where strips having a first optical property are separated by strips having a different optical property. This substrate may be composed of alternating strips of polarization film separated by clear, nonpolarizing strips. Alternately, this substrate may be composed of first alternating strips that retard a component of linearly polarized light by one-half wavelength, separated by second alternating strips that retard a component of linearly polarized light by one wavelength. A removable, separate polarizing substrate may be removably placed in front of the substrate containing the alternating strips. When the removable polarizing substrate is placed in front of the strips in a certain orientation, autostereoscopic imaging is viewed by the observer, and when this polarizing substrate is removed, 2D imaging is viewed.Type: GrantFiled: October 14, 1999Date of Patent: July 8, 2003Assignee: Dimension Technologies, Inc.Inventor: Jesse B.

The apparatus, including an illumination system, a light valve, a relay lens, a beam steering device, a plurality of projection lenses and mirrors, a focusing lens, and a screen assembly such that the mirrors focus light exiting the projection lenses and the screen assembly has a diffuser.Type: GrantFiled: January 21, 2000Date of Patent: March 18, 2003Assignee: Dimension Technologies, Inc.Inventor: Jesse B.

Patent number: 6157424Abstract: An improved 2D/3D display is disclosed. In one embodiment, the display uses both an imaging LCD and a secondary LCD. The secondary LCD is a light line forming LCD which can be placed between a light line forming system and the imaging LCD for eliminating ghost images, or can be used as the light line forming system itself. Variations of a glass sandwich employing an imaging liquid crystal layer and a line forming liquid crystal layer are disclosed. Alternatively, the secondary LCD may comprise a liquid crystal layer and a series of polarizing strips. Displays in which a 2D or 3D window can be viewed within a 3D or 2D window, respectively, are disclosed using light line forming systems and alternatively using light line forming LCD's which have the opaque stripes divided into individually controllable areas. Movement of one window within another window is disclosed. Also disclosed is a strip diffuser for improving visual characteristics in 3D mode and movable elements for alternating between 2D and 3D mode.Type: GrantFiled: March 30, 1998Date of Patent: December 5, 2000Assignee: Dimension Technologies, Inc.Inventor: Jesse B.

Patent number: 5897184Abstract: A reduced-thickness backlighter for an autostereoscopic display is disclosed having a lightguide and at least one light source parallel to an edge of the lightguide so as to be substantially coplanar with the lightguide. The lightguide is provided with a first surface which has a plurality of reflective linear regions, such as elongated grooves or glossy lines, parallel to the illuminated edge of the lightguide. Preferably the lightguide further has a second surface which has a plurality of lenticular lenses for reimaging the reflected light from the linear regions into a series of thin vertical lines outside the guide. Because of the reduced thickness of the backlighter system, autostereoscopic viewing is enabled in applications requiring thin backlighter systems. In addition to taking up less space, the reduced-thickness backlighter uses less lamps and less power.Type: GrantFiled: July 2, 1996Date of Patent: April 27, 1999Assignee: Dimension Technologies, Inc.Inventors: Jesse B Eichenlaub, Russell W Gruhlke
