A display apparatus includes a display panel, a data driver and a driving controller. The display panel includes a plurality of display blocks. The data driver is configured to output data voltages to the display panel. The driving controller is configured to control the data driver. The driving controller is configured to calculate differences between loads of a previous frame and loads of a present frame for the display blocks for each colors, to determine whether an image is a static image or not based on the differences between the loads of the previous frame and the loads of the present frame for the display blocks for the each colors, and to reduce luminance of the image when the image is determined as the static image.

Display apparatus, method of driving display panel using the same and electronic apparatus including the same

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.

Display device, method of controlling luminance of display device and electronic device

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.

Display device, method of driving the same, and electronic apparatus including the same

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.

A display device includes a display panel which displays an image, an image sticking compensator which receives image data, compensates for the image data based on lifespan data to generate lifespan compensation data, and a panel driver which provides data signals corresponding to the lifespan compensation data to the display panel. The image sticking compensator includes a compensator which receives the first cumulative data, generates the lifespan data based on the first cumulative data, compensates for the image data based on the lifespan data to generate the lifespan compensation data, a memory controller which receives the second cumulative data and the lifespan data from the compensator, a volatile memory which stores the second cumulative data from the memory controller, a main nonvolatile memory which stores the second cumulative data from the memory controller, and a sub-nonvolatile memory which stores the lifespan data from the memory controller.
