A liquid crystal display (LCD) system, comprising a matrix of pixels, analyzes a video data stream for grayscale level jumps from extreme black to moderate gray levels. Transitions in grayscale levels are restricted between adjacent pixels so as to reduce image degradation due to fringe field effects. A memory, such as a shift register, may be used to store and then grayscale levels to be written to adjacent pixels are compared and if a difference between these grayscale levels exceed a certain value then at least one of the grayscale levels is modified.
