Patent ID: 8711078

Claim:
A liquid crystal display comprising: a liquid crystal panel; and a timing controller which receives previous image data and current image data, corrects or does not correct the current image data according to a reference bit of conversion image data generated using the previous image data, and outputs a display image signal to the liquid crystal panel, wherein the display image signal is generated using a correction value which corresponds to the conversion image data and the current image data, wherein the correction value corresponding to the conversion image data and the current image data is stored in a lookup table(LUT) at a coordinate corresponding to a combination of the conversion image data and the current image data, the current image data which is not listed in the LUT is corrected to a correction value by interpolation, and wherein each of the current image data and the previous image data is divided into a plurality of groups, each group having one or more bits, and any one of the groups comprises one or more original reference bits which are converted into the reference bit.
