Abstract:
1. A display device, comprising: a display 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 driver configured to drive said display panel in accordance with said output gray-scale data; and a correction data calculation circuit configured to generate a correction data that specifies a relationship between said input gray-scale data and said output gray-scale data of said target frame image, depending on said input gray scale data of said target frame image or an input gray-scale data of a precedent frame image followed by said target frame image, wherein said operation and correction circuit determines coefficients of said arithmetic expression from said correction data, and wherein said arithmetic expression is switched between a plurality of arithmetic expressions in response to said input gray-scale data and said correction data.
