Abstract: A display device includes: a display panel including a plurality of pixels, and a panel driver configured to drive the display panel based on input image data. The panel driver determines whether a fixed image is displayed in an outermost region of the display panel based on the input image data, and decreases a luminance of the outermost region when that the fixed image is displayed in the outermost region is determined.

Abstract: A display device includes a driving controller which generates output image data based on input image data, a data driver which generates data voltages based on the output image data, and a display panel which displays an image based on the data voltages. The driving controller may generate a plurality of edge values in a first direction for a plurality of blocks based on a plurality of luminance values for the plurality of blocks that are dividing the display panel, determine a boundary area in the first direction based on a continuity of edge blocks in a second direction crossing the first direction, the edge blocks being determined based on the plurality of edge values, and generate the output image data based on the input image data and compensation data for decreasing a luminance of the image corresponding to the boundary area.

Abstract: A display apparatus includes a display panel and a display panel driver. The display panel driver drives the display panel. The display panel driver determines at least one selected from a first low luminance pattern and a second low luminance pattern, where the first lower luminance pattern includes a first low luminance area at a first end portion of the display panel in a vertical direction and a second low luminance area at a second end portion of the display panel in the vertical direction, and the second low luminance pattern includes a third low luminance area at a first end portion of the display panel in a horizontal direction and a fourth low luminance area at a second end portion of the display panel in the horizontal direction. The display panel driver determines a compensation area including a boundary between a low luminance area and a normal area.
