Patent ID: 8405590

Claim:
A liquid crystal display comprising: a plurality of pixels; an image signal modifier that generates a preliminary signal based on a previous image signal and a current image signal and generates a modified image signal based on the preliminary signal and a next image signal; and a data driver that changes the modified image signal from the image signal modifier into a data voltage and supplies it to the pixels, wherein the modified image signal has at least two different values depending on a magnitude of the next image signal, wherein when the preliminary signal is less than a first predetermined value, and the next image signal is more than a second predetermined value and less than a third predetermined value, the modified image signal has a first modification value, and when the preliminary signal is less than the first predetermined value, and the next image signal is more than the third predetermined value, the modified image signal has a second modification value that is different from the first modification value, wherein the first predetermined value is an upper threshold of the preliminary signal, the second predetermined value is a lower threshold of the next image signal, and the third predetermined value is a reference value of the next image signal.
