Patent number: 8154686Abstract: A directional backlight, a multiple view display and a multi-direction display A multiple view display (18) comprises a directional display device (19) for displaying a first image or sequence of images so as to be mainly visible from a first range of directions relative to the device and for simultaneously displaying a second image or sequence of images so as to be mainly visible from a second range of directions relative to the device different from the first range. The display (18) further comprises a directional backlight (20) for directing light through the display device (19) at least mainly in the first and second ranges. Since the directional backlight (20) directs light through the display device (19) at least mainly in the first and second ranges, the display provides users located in the first and second ranges with images of greater intensity than a conventional display.Type: GrantFiled: January 21, 2005Date of Patent: April 10, 2012Assignee: Sharp Kabushiki KaishaInventors: Jonathan Mather, Neil Barratt, Diana U. Kean, Emma J. Walton, Grant Bourhill, Thomas Wynne Powell

Patent number: 8144079Abstract: Techniques are disclosed for reducing the visibility of crosstalk between images in a multiple view display for simultaneously displaying two or more images independently of each other for viewing in different directions by different viewers. A multiple view display typically comprises a liquid crystal panel (20) and a parallax barrier (21) forming a dual view display for two viewers. The panel (20) comprises an array of pixels of elongate shape and arranged so as to be elongate in the horizontal direction of the normal image orientation on the panel (20). Crosstalk compensation may be provided in a display controller for the display.Type: GrantFiled: January 25, 2006Date of Patent: March 27, 2012Assignee: Sharp Kabushiki KaishaInventors: Jonathan Mather, David J. Montgomery, Graham R. Jones, Diana U. Kean

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: 7782409Abstract: A multiple view display comprises a display device such as a liquid crystal device, a parallax optic such as a parallax barrier, and a controller. The device comprises rows and columns of pixels and the controller supplies image data for a first view to first ones of the pixels and second ones of the pixels such that the first and second pixels alternate in the rows and in the columns. The parallax optic comprises rows and columns of parallax elements with the arrangement of pixels and parallax elements being such that each element co-operates with a respective pair of first and second pixels adjacent each other in the same row to form first and second viewing regions. Each row of parallax elements is off-set in the row direction by half the horizontal barrier pitch. Such an arrangement allows wider angles between the viewing regions to be achieved.Type: GrantFiled: December 5, 2003Date of Patent: August 24, 2010Assignee: Sharp Kabushiki KaishaInventors: Diana U. Kean, David James Montgomery, Grant Bourhill, Jonathan Mather

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
