  • Position detection system, display panel, and display device
    Patent number: 8823684
    Abstract: Disclosed are: a position detection system having improved flexibility in selection of line sensors; and others. In the position detection system (PM) of the present invention, a phosphor (11) which can excite invisible light (UV light) that is light emitted from an LED (23) is arranged on an optical path between the LED (23) and a light receiving element (26).
    Type: Grant
    Filed: June 29, 2010
    Date of Patent: September 2, 2014
    Assignee: Sharp Kabushiki Kaisha
    Inventors: Atsuhito Murai, Takehiro Murao, Seishi Kosegawa, Yukihiko Nishiyama, Hideki Kitagawa

  • OPTICAL SENSOR CIRCUIT, TWO-DIMENSIONAL COORDINATE DETECTION APPARATUS, INFORMATION PROCESSING APPARATUS, AND METHOD OF REFRESH-DRIVING OPTICAL SENSOR ELEMENT
    Publication number: 20120250033
    Abstract: An optical sensor circuit in accordance with the present invention detects, based on a change in the amount of light received when a pointer (P) is placed in a coordinate detection area (2) through which light from a light source (3) passes, coordinates of a position of the pointer (3) in the coordinate detection area (2).

  • OPTICAL SENSOR CIRCUIT, DISPLAY PANEL, DISPLAY DEVICE, AND METHOD FOR DRIVING AN OPTICAL SENSOR CIRCUIT
    Publication number: 20120241768
    Abstract: An optical sensor circuit (20) includes a transistor (20c) and a transistor (20d). The transistor (20c) is connected in series with the transistor (20d). The transistor (20d) is configured to receive light. A black matrix is provided so as to face the transistor (20c). A voltage generated at a connecting point (i.e., node (netB)) of the transistor (20d) and the transistor (20c) varies depending on intensity of light received via the transistor (20d).

  • Touch panel, display device and touch panel manufacturing method
    Patent number: 8243032
    Abstract: A touch panel includes an insulating substrate, a transparent touch electrode provided on the insulating substrate, and a frame portion connected to a periphery of the touch electrode. The touch panel detects a touched position on the touch electrode based on an electric signal through the frame portion. The frame portion is provided between the insulating substrate and the touch electrode.
