    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.

    摘要: In one embodiment of the present invention, the liquid crystal display device of the invention performs an overshoot drive, including: an LCD having a liquid crystal panel for displaying video image; a frame memory installed outside of the LCD; and lookup table, the table with which third gray scale data most suitable for performing the overshoot drive to the LCD can be computed based on first gray scale data of a first frame and second gray scale data of a second frame, where the second frame is a frame right before the first frame and is stored in the frame memory in advance, wherein lookup table data is stored for each response speed characteristic of the LCD. Thus, without rewriting of lookup table data, the liquid crystal display device having the lookup table most suitable for performing the overshoot drive is realized while high display quality is maintained therein.

    摘要: 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.

    摘要: In one embodiment of the present application, an area control section receives a command specifying a video image display area or a dynamic image display area in the image data. The area control section stores a data of a previous frame screen in the frame memory only for the part which an overdrive is performed, based on the command. A control section outputs a received image data to a source drive section as it is for the image data being notified as a still image display area. For the image data being notified as a video image display area, the image data is converted based on a data stored in a Look-up Table, and performs the display which improves the response speed of the liquid crystal.
