Abstract:
An LCD device according to the present invention has: an LCD panel; an operation and correction circuit configured to perform a correction operation with respect to an input gray-scale data of a target frame image by using an arithmetic expression to generate an output gray-scale data; a data line driver configured to drive the LCD panel in accordance with the output gray-scale data; and a correction data calculation circuit configured to generate a correction data that specifies a relationship between the input gray-scale data and the output gray-scale data of the target frame image, depending on the input gray-scale data of the target frame image or an input gray-scale data of a precedent frame image followed by the target frame image. The operation and correction circuit determines coefficients of the arithmetic expression from the correction data.
