| 20090128746 | DISPLAY - 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. In the second state, liquid crystal molecules of the at least one region are tilted with respect to the normal axis of the display over at least a portion of the thickness of the liquid crystal layer, and lie substantially parallel to a plane defined by the normal axis of the display and the transmission axis or absorption axis of the first polarizer or one of the first and second polarizers. | 05-21-2009 |
| 20090168164 | MULTIPLE-VIEW DIRECTIONAL DISPLAY - A multiple view directional display comprises a pixellated image display layer having a plurality of first pixels (P | 07-02-2009 |
| 20110012924 | DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY PANEL - 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. | 01-20-2011 |

| 20110210829 | Method of Actively Tagging Electronic Designs and Intellectual Property Cores - In an embodiment of the invention, an active security tag is embedded within the digital logic of an electronic design for logic destined for an integrated circuit such as an FPGA. The security tag includes security tag data which permits identification of the electronic design, and facilitates efforts to enforce copyrights in the designs. The security tag also includes a transmitter designed to covertly transmit security tag data to a receiver. Other information, such as error information and status information about the integrated circuit may also be transmitted. The transmitted information is concealed from detection by being hidden within background noise signals or other signals created by normal usage of the integrated circuit. | 09-01-2011 |
