Abstract: A display apparatus includes a display panel including a plurality of pixels, and a driver which receives input image data, generates final image data by compensating the input image data to increase luminances of pixels disposed in at least one edge portion of the display panel among the plurality of pixels, and drives the display panel based on the final image data. The input image data for a pixel of the pixels is compensated based on a compensation constant determined according to a position of the pixel when the input image data for the pixel represents a gray level higher than or equal to a first reference gray level, and is compensated based on a reduced compensation constant that is reduced from the determined compensation constant when the input image data for the pixel represents the gray level lower than the first reference gray level.

Abstract: A display device includes a display panel comprising a plurality of pixels, a data driver configured to generate data voltages based on a gamma reference voltage, and to provide the data voltages to the plurality of pixels, a gate driver configured to provide gate signals to the plurality of pixels, and a controller configured to control the data driver and the gate driver. The controller is configured to initialize the gamma reference voltage when a blank period starts in a frame period comprising an active period and the blank period, and to change the gamma reference voltage when a duration of the blank period reaches at least one threshold time.
