  • Display
    Patent number: 8314918
    Abstract: A display includes a display device having a first polarizer and a second polarizer or a reflector, and a display layer disposed between the first polarizer and the second polarizer or the reflector. A liquid crystal layer is disposed between the display layer and one of the first polarizer and the second polarizer or reflector. The liquid crystal molecules of at least one region of the liquid crystal layer are switchable between a first state in which the display has a first display mode with a first viewing angle range and a second state in which the display has a second display mode having a second viewing angle range smaller than the first viewing angle range.

  • Display
    Patent number: 8289458
    Abstract: A display is switchable between a first display mode with a first viewing angle range, a second display mode having a second viewing angle range smaller than the first viewing angle range and a multiple view directional display mode. The display includes an image display layer and a control element that is switchable between a first state in which it cooperates with the image display layer to provide the first display mode, a second state in which it cooperates with the image display layer to provide the second display mode, and a third state in which it cooperates with the image display layer to provide the multiple view directional display mode.

  • MULTIPLE VIEW DISPLAY SYSTEM
    Publication number: 20090109126
    Abstract: An interactive multiple view display system has a multiple view display which displays images of independently selectable content so as to make them visible in respective different viewing regions. A detection arrangement detects which of a plurality of users is attempting to interact with one of the displayed images. An interaction arrangement then permits the detected user to interact with the image.
