Patent ID: 8354988

Claim:
A liquid crystal display device comprising: a liquid crystal display panel including first sub-pixels for charging a data of a polarity opposite to a prior horizontal period, and second sub-pixels for charging a data of a polarity identical to a prior horizontal period; a data driver for driving a plurality of data lines of the liquid crystal display panel; and a timing controller for dividing a charging period of the data into a plurality of charging periods, generating at least one compensation data for compensating a data on at least one of the plurality of charging periods, and supplying the at least one compensation data to the data driver, wherein the timing controller generates a first compensation data having a gray scale higher than a gray scale of an original data only in one of a plurality of charging periods of only the first sub-pixels, and generates a second compensation data having a gray scale lower than a gray scale of an original data only in one of a plurality of charging periods of only the second sub-pixels.
