Patent ID: 7777707

Claim:
A computer system comprising a liquid crystal display (LCD) device and a processor, wherein the LCD device has a number of pixels, and wherein the processor is configured to determine an overdrive value for a pixel in the LCD device to change from a starting pixel value to a target pixel value by: reading data from a factored zero-diagonal n×n LCD overdrive matrix that stores data related to the overdrive values for a number of pixel starting and target values, wherein the data stored on the main diagonal of the factored zero-diagonal LCD overdrive matrix are derived from a partial derivative of a function that describes a response of the LCD device; and determining an overdrive value for a pixel by: using the data read from the factored zero-diagonal LCD overdrive matrix to determine the overdrive value if the factored zero-diagonal LCD overdrive matrix stores data for the starting and target values; or using data interpolated from the factored zero-diagonal LCD overdrive matrix to determine the overdrive value if the factored zero-diagonal LCD overdrive matrix does not store data for the starting and target values.
