Abstract: An image characteristic judgement circuit analyzes input image data and obtains first brightness data indicating brightness of a backlight within a single vertical period and image characteristic data corresponding to the first brightness data. In at least one embodiment, an image data conversion circuit performs conversion to the input image data according to the image characteristic data and outputs the image data after the conversion to a liquid crystal panel. A period-by-period brightness calculation circuit obtains, based on the first brightness data, second brightness data indicating brightness of the backlight within each of a plurality of periods into which the single vertical period is divided. A brightness setting circuit 18 controls the brightness of the backlight using the second brightness data. Flickers in a screen are reduced by changing the brightness of the backlight within a single vertical period in this manner.

Abstract: 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.
