  • Patent number: 11830404
    Abstract: A display apparatus includes a display panel, an afterimage compensator and a data driver. The display panel displays an image. The afterimage compensator writes first stress data of input image data corresponding to a first area to a first memory area in a first block size and second stress data of the input image data corresponding to a second area to a second memory area in a second block size different from the first block size and compensates a grayscale value of the input image data based on the first stress data and the second stress data. The data driver generates a data voltage based on a compensated grayscale value and outputs the data voltage to the display panel.
