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 plurality of shift registers, may be used to store grayscale levels of adjacent pixels which are compared and if a ratio between these grayscale levels exceeds a desire value then at least one of the grayscale levels is modified.
