  • Patent number: 8384639
    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.

  • Patent number: 8237753
    Abstract: A gradation conversion unit 23 performs, on an input image, gradation conversion in which a predetermined gain is applied to a gradation smaller than a boundary gradation CVth and a characteristic becomes a spline curve for a gradation larger than the boundary gradation. To determine a characteristic of the gradation conversion unit 23, an image analysis unit 22 obtains the boundary gradation CVth and a maximum gradation CVmax based on the input image, and determines a linear gain shift coefficient LGs so that the brightness decreasing rate of the maximum gradation CVmax when brightness control of a backlight 30 is performed becomes a limit value or less. In such a manner, power consumption of the backlight is reduced while suppressing deterioration in picture quality.

  • Patent number: 8120563
    Abstract: A display ON sequence for preventing problems in a display at the starting time of a liquid crystal display device is prevented from having malfunctions, which might otherwise be caused in a scanning line drive circuit by applying a voltage to scanning signal lines. In the display ON sequence at the starting time of the liquid crystal display device of an active matrix type, all the scanning signal lines of a liquid crystal panel are brought into a selected state thereby to release the electric charges in the liquid crystal capacity and the auxiliary capacity in each pixel forming portion through data signal lines. After this, the scanning signal lines are stepwise brought into an unselected state by dividing them several times, before their sequential selections (or scans) for the display are started.

Gate-bus lines are provided at both top and bottom sides of each row. Two sub-pixels are formed at a region surrounded by two adjacent source-bus lines and two adjacent gate-bus lines. At the odd-numbered rows, for the left-side sub-pixel of those two sub-pixels, a scanning signal is supplied from the top-side gate-bus line, while a video signal is supplied from the left-side source-bus line. For the right-side sub-pixel, on the contrary, a scanning signal is supplied from the bottom-side gate-bus line, while a video signal is supplied from the right-side source-bus line. At the even-numbered rows, the gate-bus line from which a scanning signal is supplied is reversed to the case of the odd-numbered rows. The gate-bus lines are sequentially selected one by one, and all the video signal polarities are made the same during each horizontal scanning period.

  • Publication number: 20110193888
    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.
