Display control circuit, liquid crystal display device provided therewith, and display control method

2:

• The display control circuit according to claim 1, further comprising:
• for each of the colors, overshoot tables defined by:
• a current frame gradation level to be applied in a current frame;
• a gradation level that has been written in an immediately preceding frame;
• and
• an overshoot parameter for every combination of current frame gradation level and a gradation level that has been written in an immediately preceding frame,
• wherein the overshoot driving unit reads the overshoot parameter from the overshoot table of the corresponding color to generate gradation data to be actually written for image display.

4:

• The display control circuit according to claim 3,
• wherein, for each color, the overshoot parameter is found by the calculation in a formula:
• V=P+(Q−P)×C, and
• wherein V represents the overshoot parameter, P represents a gradation level that has been written in an immediately preceding frame, Q represents a current frame gradation level to be applied in a current frame, and C represents the coefficient of the corresponding color.

6:

• A liquid crystal display device, comprising:
• the display control circuit according to claim 1;
• a liquid crystal display panel, including:
• a plurality of image signal lines that transmit a plurality of image signals corresponding to the write gradation data for image display;
• a plurality of scan signal lines that intersect with the plurality of image signal lines;
• a plurality of pixel forming areas arranged in a matrix along the plurality of image signal lines and the plurality of scan signal lines;
• and
• a common electrode that applies a common voltage to the plurality of pixel forming areas;
• an image signal driving circuit that drives the plurality of image signal lines;
• and
• a scan signal driving circuit that drives the plurality of scan signal lines.

7:

• A method of controlling display in which gradation data is generated that is to be written to a liquid crystal display panel that displays images on the basis of image signals expressing gradation levels for colors, the method comprising:
• performing white balance processing by adjusting the gradation level of each color expressed by the image signals using white balance parameters determined for each of the gradation levels of each color;
• and
• performing overshoot processing by generating the gradation data to be actually written for image display and generating a corresponding voltage applied to the liquid crystal display panel, said overshoot processing generating, for each of the colors, prescribed overshoot parameters as the actual gradation data to be written in accordance with a current frame gradation level to be applied in the current frame and a gradation level that has been written in an immediately preceding frame so as to emphasize a gradation level change,
• wherein among the respective colors, the more a maximum gradation level of of a particular color is decreased in the step of white balance processing, the greater the gradation level change for that particular color is emphasized in the step of overshoot processing.
