Abstract:
1. A liquid crystal display comprising: a liquid crystal panel assembly including a plurality of pixels; a gray signal modifier classifying a plurality of pairs of current gray signals and previous gray signals into at least two groups based on characteristics of a difference between the current gray signals and the previous gray signals and modifying the current gray signals based on a corresponding group of the at least two groups to generate a plurality of modified gray signals; wherein the gray signal modifier comprises: a data driver converting the modified gray signals into corresponding image signals and providing the corresponding image signals to the pixels; wherein the current gray signals and the previous gray signals have most significant bits (“MSBs”) and least significant bits (“LSBs”); and wherein the modified gray signals for the pairs where the LSBs of the current gray signals and the LSBs of the previous gray signals are zero are predetermined, and the variables are determined in accordance with the predetermined modified gray signals.
