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: An image processing method includes receiving an RGB data, converting the RGB data to an HSV data configured to include hue, saturation, and value compensating for the HSV data on a basis of a hue data of the HSV data, and converting the compensated HSV data to a compensated RGB data. The compensating of the HSV data includes reading out a compensation data corresponding to the hue data from a look-up table and compensating for the HSV data using the compensation data. The data are compensated on the basis of the hue in the HSV color space and the saturation and value are preserved, and thus the image, e.g., the memory color like the skin color, may be prevented from being distorted.
