Abstract
A controller circuit ( ) for processing video data for an active matrix liquid crystal display device has processing circuitry for performing correction functions on the input video data (D) prior to being supplied to the drive circuit ( ) of the display device comprising gamma and color correction, and correction for reducing motion blur in the display picture. The correction circuits ( ) are organized such that correction for motion blur reduction ( ) is carried out before the gamma and color corrections ( ), which enables a beneficial decrease in semiconductor area required when implementing the circuitry in IC form through the size of field store ( ) and LUT ( ) components used for this function then being smaller. Gamma and color corrections are performed together using a single LUT. Correction for kickback may further be included, such correction preferably being arranged after the gamma and color corrections and using a separate LUT.
