  • Liquid crystal display device
    Patent number: 6747641
    Abstract: In a liquid crystal display device that achieves display by using an active-matrix liquid crystal panel, for a predetermined time after the driving of the liquid crystal panel is stopped, a voltage is kept applied only to the opposing electrode through which all the liquid crystal layers constituting the liquid crystal panel are driven. This helps shorten the time required for the electric charge accumulated in the liquid crystal panel to be discharged and thereby prevent degradation of display quality and deterioration of the liquid crystal panel through simple control.
    Type: Grant
    Filed: August 1, 2001
    Date of Patent: June 8, 2004
    Assignee: Sharp Kabushiki Kaisha
    Inventors: Moritaka Nakamura, Manabu Tanaka, Yugo Kasai
