Patent ID: 8605138

Claim:
A method of driving an image display device, the method comprising: inserting a reset frame displaying black data between neighboring data frames alternately displaying left-eye data and right-eye data; reflecting gray-scale information of an (n−2)th data frame in a reset frame corresponding to an (n−1)th frame through a predetermined data calculating operation; detecting a data variation between the (n−1)th reset frame and an nth data frame, reading a compensation value corresponding to the detection result from a lookup table, and modulating input data of the nth data frame using the read compensation value; and inverting the polarity of the modulated data according to N frame inversion (N is a multiple of 4) and applying the data having the inverted polarity to a display panel, wherein the gray-scale information reflected in the (n−1)th reset frame is calculated as a gray-scale value corresponding to 1/k (k is a positive integer greater than 2) or 1/j (j is a positive integer greater than 4) of the input gray-scale value of the (n−2)th data frame in the data calculating operation, and wherein each of the 1/k and the 1/j defines a data accessible region in the lookup table.
