Claim Text:
1. A method of driving a display panel, the method comprising: generating compensated grayscale data by increasing grayscale data corresponding to an N-th gate line of a plurality of gate lines of the display panel, wherein N is a natural number; generating, by a data driver, a data voltage based on the compensated grayscale data, and outputting the data voltage to the display panel including a plurality of pixel electrodes and a plurality of data lines, wherein each of the plurality of data lines is alternately connected to the plurality of pixel electrodes in a first pixel column and the plurality of pixel electrodes in a second pixel column; generating, by a storage voltage generator, a storage voltage having a first level and a second level, wherein the second level is lower than the first level; and applying, by the storage voltage generator, the storage voltage to a storage electrode of the display panel, wherein the storage voltage is applied to the display panel based on a gate signal from a gate line of the plurality of gate lines, and wherein the grayscale data corresponding to the plurality of data lines except for the grayscale data corresponding to an M-th data line of the plurality of data lines are increased when a display error is detected at the grayscale data corresponding to the M-th data line, wherein M is a natural number.
