Patent number: 7813042Abstract: A parallax optic comprises plural, spaced apart lenses which are separated by regions which are non-transmissive of/to visible light. In some embodiments, the spaced apart lenses of the parallax optic are discrete elements of a lens array. In other embodiments, the lens elements are formed as convex elements integral with and extending from a lenticular layer. Parallax optic devices are combined with one or more image display elements to form an image display device. For embodiments of image display devices featuring or providing two-dimensional (2D) viewability, the parallax optic is preferably near or included in the image display element. On the other hand, for embodiments of image display devices featuring or providing three-dimensional (3D) viewability, the parallax optic is situated outside the image display element.Type: GrantFiled: March 2, 2006Date of Patent: October 12, 2010Assignee: Sharp Kabushiki KaishaInventors: Jonathan Mather, Robert Winlow, Akira Nakagawa, Diana U. Kean, Grant Bourhill

Patent number: 7697080Abstract: A multiple-view directional display is provided having an image display element and a parallax optic (13). The display element (8) comprises substrates (6, 19) between which the display layer (8) is sandwiched and the parallax optic (13) is disposed within the image display element.Type: GrantFiled: February 20, 2008Date of Patent: April 13, 2010Assignee: Sharp Kabushiki KaishaInventors: Jonathan Mather, Robert Winlow, Akira Nakagawa, Diana U. Kean, Grant Bourhill

Patent number: 7633586Abstract: A display is provided for switching between a narrow or private viewing mode and a wide or public viewing mode. The display comprises a display device which is controlled to provide display of a desired image or sequence of images. This is associated with a liquid crystal device having at least one liquid crystal layer whose molecules are switchable between a first state providing a first angular viewing range and a second state providing a second angular viewing range which is within and smaller than the first angular viewing range. With the molecules in the second state, the device at least partially blocks light propagating towards part of the first angular viewing range outside the second angular viewing range. The or each liquid crystal layer is in contact with at least one alignment surface, the or each of which comprises a uniform non-patterned alignment surface.Type: GrantFiled: April 19, 2005Date of Patent: December 15, 2009Assignee: Sharp Kabushiki KaishaInventors: Robert Winlow, Zabbie J. Acosta, Martin D. Tillin, Paul Bonnett, Diana U. Kean, Grant Bourhill, Michel Sagardoyburu, Emma Jayne Walton, Koji Yabuta, Hiroshi Fukushima, Tomoo Takatani

Patent number: 7580186Abstract: A multiple view display comprises a display device which displays first and second images in a spatially multiplexed fashion across the display surface. The device cooperates with a parallax optic such as a lenticular screen so as to act as a directional display sub-system directing light from the first and second images in different viewing directions. An optical system, for example comprising a lenticular screen of diverging elements, changes the angular separation of the viewing angle directions, for example so as to increase the angular separation.Type: GrantFiled: August 27, 2004Date of Patent: August 25, 2009Assignee: Sharp Kabushiki KaishaInventors: Jonathan Mather, David J. Montgomery, Robert Winlow, Grant Bourhill, Neil W. Barrett

Publication number: 20090067156Abstract: An illumination system (32) is provided for producing output light having a variable angular illumination range for illuminating a display panel (31) in a display device (30). The illumination system (32) comprises first and second light sources (34 and 36) and is operable selectively in a first mode in which the output light comprises light derived from the first light source (34) with substantially no light derived from the second light source (36), and in a second mode in which the output light comprises light derived from at least the second light source (36). The output light derived from the first light source (34) has a first angular illumination range and the output light derived from the second light source (36) has a second angular illumination range wider than the first angular illumination range. The first mode can be used as a private mode and the second mode can be used as a public mode.Type: ApplicationFiled: January 14, 2005Publication date: March 12, 2009Applicant: SHARP KABUSHIKI KAISHAInventors: Paul Bonnett, Grant Bourhill, Allan Evans, Adrian M.S.
