Abstract: A display device includes: a display panel, which displays an image; a panel driver, which drives the display panel; and a driving controller, which controls a drive of the panel driver. The driving controller includes a compensation determination block and a data compensation block. The compensation determination block is activated after a still image is displayed for a predetermined time or more and generates a compensation value based on a final afterimage component calculated using an afterimage algorithm obtained by a combination of a first afterimage calculation equation and a second afterimage calculation equation. The data compensation block receives an image signal with respect to a target image and reflects the compensation value to the image signal to generate a compensation image signal.

Abstract: A display apparatus includes a display panel, a driving controller and a data driver. The display panel is configured to display an image. The driving controller is configured to generate a compensated image data for compensating a decrease of a luminance of an edge portion of the display panel based on input image data. The data driver is configured to output a data voltage to the display panel based on the compensated image data. The driving controller is configured to generate the compensated image data by comparing a maximum value among subpixel grayscale values of the input image data to which a luminance compensating coefficient is applied and a maximum grayscale value of the input image data. The luminance compensating coefficient is configured to be determined according to a location in the display panel.
