Patent number: 8698718Abstract: A display device is provided that comprises a liquid crystal display panel for displaying an image by spatial light modulation, and circuitry for switching liquid crystal in the panel between having a first configuration in a first mode to cause an image displayed using the panel to be discernible from a wide range of viewing angles, and having a second configuration in a second mode to cause an image displayed using the panel to be discernible substantially only from within a narrow range of viewing angles. Several types of display panel to achieve such in-panel switching between public and private viewing modes are disclosed.Type: GrantFiled: September 22, 2011Date of Patent: April 15, 2014Assignee: Sharp Kabushiki KaishaInventors: Paul Antony Gass, Diana Ulrich Kean, Nathan Smith, Thomas Mathew Wynne-Powell, Allan Evans, Benjamin John Broughton

Publication number: 20110122329Abstract: A display for providing several viewing modes of different angular viewing characteristics comprises a display device and a passive optical device (9) of a parallax optic of fixed optical characteristics. The display device comprises a light emitting or modulating layer (7) between first and second electrode arrangements (5, 10, 11). The first electrode arrangement (5) comprises a plurality of pixel electrodes defining pixels of the display device. The second electrode arrangement comprises a plurality of counter electrodes (10, 11) arranged so that each of the pixel electrodes (5) faces a portion of each of the counter electrodes. The counter electrodes are controllable so as to select which portion of each pixel is active. This provides, in cooperation with the optical device (9) the plurality of display viewing modes.Type: ApplicationFiled: February 20, 2009Publication date: May 26, 2011Applicant: SHARP KABUSHIKI KAISHAInventors: Benjamin John Broughton, Allan Evans, Michel Sagardoyburu, Nathan James Smith, Lesley Anne Parry-Jones, Diana Ulrich Kean

Patent number: 7154653Abstract: A parallax barrier comprises evenly spaced groups of slits. Each group comprises two or more slits which are evenly spaced and the groups are spaced with a period which is greater than the product of the number of slits in each group and the slit period in each group. Such a barrier may be used with a spatial light modulator having columns of pixels whose structure cooperates with the barrier structure to provide a wider angle between views in a multiple view display, such as an autostereoscopic 3D display or a display providing two or more different views to two or more observers.Type: GrantFiled: March 18, 2004Date of Patent: December 26, 2006Assignee: Sharp Kabushiki KaishaInventors: Diana Ulrich Kean, David James Montgomery, Jonathan Mather, Grant Bourhill, Graham R.
