摘要:
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.
