Patent number: 8384639Abstract: A drive circuit of a liquid crystal display device performs line inversion drive based on a correction video signal V. A look-up table (12) includes two types of tables having stored therein correction values for use in overshoot drive. Based on a current-frame video signal X, a previous-frame video signal Y stored in a frame memory (11), and a polarity-reversing signal REV, a correction process portion (13) reads a correction value from the look-up table (12), and outputs the correction value being read as the correction video signal V. In such a manner, a correcting circuit (10) is used to control the degree of overshoot in accordance with the polarity-reversing signal REV. Thus, it is possible to suitably control the change in pixel brightness regardless of the polarity of the applied voltage, thereby preventing any fringes from being generated while displaying moving images.Type: GrantFiled: October 25, 2006Date of Patent: February 26, 2013Assignee: Sharp Kabushiki KaishaInventors: Kozo Takahashi, Asahi Yamato, Kiyoshi Nakagawa, Takaaki Kawai

Patent number: 7978164Abstract: A control section (6) merely passes an incoming image data signal DAT onto a source driving section for display driving during the display of a still image. During the display of a moving image, the control section (6) converts, using a computing section (61) and a look-up table (5), a grayscale level signal in the incoming image data signal DAT to a grayscale level signal that is obtainable without using those application voltages at which the response speed of liquid crystal is slow. The control section (6) then outputs the resultant grayscale level signal to the source driving section for display driving.Type: GrantFiled: March 24, 2006Date of Patent: July 12, 2011Assignee: Sharp Kabushiki KaishaInventors: Yuki Kawashima, Asahi Yamato, Kohzoh Takahashi, Kiyoshi Nakagawa, Toshihiro Yanagi
