Abstract: A display device includes an afterimage compensator generating output grayscales by applying at least one of first and second weights to input grayscales when the input grayscales correspond to a still image, and pixels displaying an image based on the output grayscales. The afterimage compensator applies the first weight having an initial value greater than 1 to the input grayscales of a first group, and converges the first weight to 1, and applies the second weight having initial values less than 1 to the input grayscales of a second group, and converges the second weights to 1.

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.

Abstract: A display apparatus includes a display panel, a driving controller and a data driver. The driving controller processes input image data according to a variable input frequency and generates a data signal having a varied frame length. The data driver converts the data signal into a data voltage and outputs the data voltage to the display panel. The driving controller determines a variable frequency mode and generates an asymmetric data signal including a positive data signal and a negative data signal which are asymmetric with respect to a common voltage for a same grayscale value in the variable frequency mode.
