摘要： 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.

摘要： Provided is a display device. The display device includes: a gamma mapping unit; a compensating signal generation unit including a limit gray scale determination unit outputting a white limit gray scale value; and a hue control compensation unit including a main color compensation unit and a white compensation unit. The white compensation unit decreases a gray scale value of the white image signal based on the white limit gray scale value to generate the white compensated signal and the main color compensation unit compensates the red, green and blue image signals based on the white limit gray scale value to generate the red, green and blue compensated signals, when gray scale value of the white image signal is larger than the white limit gray scale value.
