Patent number: 10152942Abstract: 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.
