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.

Abstract: A display apparatus includes a display panel, a driving controller, a gate driver and a data driver. The driving controller is configured to insert a compensation image to first image data including a normal image to generate second image data. The gate driver is configured to shift an output time of a gate signal and to output the gate signal having a shifted output time to the display panel. The data driver is configured to generate a data voltage based on the second image data and to output the data voltage to the display panel. A gate shift amount when the compensation image is applied is substantially the same as a gate shift amount immediately before the compensation image is applied.
