Patent ID: 8736528

Claim:
A liquid crystal display comprising: a liquid crystal panel divided into a plurality of display regions, each of the plurality of display regions having a plurality of pixels; and a timing controller receiving a primitive image signal for displaying an image in the display regions, and correcting the primitive image signal using a plurality of dithering patterns respectively corresponding to the plurality of display regions, wherein the timing controller comprises a dithering unit correcting the primitive image signal corresponding to the display regions; the dithering unit comprises a dithering pattern selector choosing the dithering patterns respectively corresponding to the display regions and a dithering processor applying the selected dithering patterns to the display regions; and the timing controller further comprises a memory unit storing the plurality of dithering patterns and a plurality of identification values that respectively identify the dithering patterns, wherein the dithering pattern selector comprises a default value generator generating a plurality of default values respectively corresponding to the display regions and a dithering pattern determiner determining the identification values respectively corresponding to the default values and applying the dithering patterns respectively corresponding to the determined identification values to the display regions, wherein ones of the plurality of display regions that are in contact with each other on at least one side in a same column correspond to different ones of the plurality of dithering patterns, wherein the display regions include a first display region and four second display regions contacting with upper, lower, left and right sides, respectively, of the first display region, and wherein the dithering pattern corresponding to the second display region on the upper side of the first display region is the same as one of the dithering patterns respectively corresponding to the second display regions on the right and left sides of the first display region, and the dithering pattern corresponding to the second display region on the lower side of the first display region is the same as the other of the dithering patterns respectively corresponding to the second display regions on the right and left sides of the first display region.
