The lenticular elements have optical focal axes that are slanted at an angle to the display pixel columns. Display areas of the display pixels have edges that are substantially parallel to the lenticular element axes so that pixels of different views are prevented to be projected to the same viewing zone, thereby preventing crosstalk between views and reducing light intensity variations (due to varying amount of the opaque black mask which is imaged. The light intensity output also varies across each pixel display area in a direction perpendicular to the lenticular element axes.Type: GrantFiled: December 12, 2006Date of Patent: September 21, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Hans Zuidema, Harry Kuijpers, Laurens Doornhein

Patent number: 7777950Abstract: It is made possible to provide a stereoscopic image display apparatus capable of preventing the stereoscopic display characteristics from being degraded even if the locus of light rays between the lens and the two-dimensional display device becomes long. A stereoscopic image display apparatus includes: a plane display device having a display face formed of a plurality of pixels arranged in a matrix form; an optical plate comprising a plurality of lenses which are arranged in front of the display face of the plane display device and which have a uniaxial double refractive material inserted therein, and controlling light rays from the pixels; and a sheet polarizer provided between the plane display device and the optical plate to align a polarization direction of light ray. In the double refractive material, a maximum primary axis of refractive index is parallel to ridgelines of the lenses and is inclined in a direction opposed to a viewer.Type: GrantFiled: March 19, 2008Date of Patent: August 17, 2010Assignee: Kabushiki Kaisha ToshibaInventors: Ayako Takagi, Yuzo Hirayama
