    Abstract: A display apparatus includes a timing controller, a data driver and a display panel. The data driver generates a positive polarity data voltage and a negative polarity data voltage based on image data compensated by the timing controller. The display panel includes a first pixel driven based on the positive polarity voltage and a second pixel driven based on the negative polarity voltage. The display panel receives a storage voltage applied to the first pixel and the second pixel. The timing controller compensates the image data when a variation on a level of the storage voltage occurs. The compensation shifts a level of the first data voltage from a first normal level to a first compensation level in a direction, and shifts a level of the second data voltage from a second normal level to a second compensation level in the same direction.
