Abstract: A display apparatus includes a display panel, a driving controller, and a data driver. The display panel is configured to display an image based on input image data. The driving controller is configured to determine whether the input image data include a display quality deteriorating pattern. The driving controller is configured to determine a first compensation value for compensating a first area disposed at a first side of a main area of the display quality deteriorating pattern and a second compensation value for compensating a second area disposed at a second side of the main area opposite to the first side of the main area, according to a position of the main area. The data driver is configured to apply a data voltage to the display panel using the first compensation value and the second compensation value.
