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 including: a display panel including a route region located in the display region; and a drive controller configured to generate image data such that a reference point of the image is shifted along a shift route, the route region includes a center point, first to fourth points, and first to fourth sides, the shift route includes a first route that includes: a first sub-route along which the reference point moves from the center point to the first point; a second sub-route along which the reference point moves from the first point to the third point; a third sub-route along which the reference point moves from the third point to the second point; a fourth sub-route along which the reference point moves from the second point to the fourth point; and a fifth sub-route along which the reference point moves from the fourth point to an end point.

Display device and an 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.

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

A display device includes a display panel divided into panel blocks including pixels, and a display panel driver which drives the display panel, sets a time point to which a set time elapses from a time point when input image data is determined to be a still image as an operation time point, decreases a luminance gain from the operation time point, determines the set time based on accumulated deterioration amounts of the panel blocks, and applies the luminance gain to the input image data.

Display device

A display device includes a display panel and a display image shift controller. The display panel includes a display area in which a display image is displayed and a shift area located within the display area. The display image shift controller generates a route shift signal, where a reference point of the display image is shifted in the shift area based on the route shift signal. The route shift signal includes first and second routes corresponding to a path through which the reference point of the display image is shifted. The first route includes a first sub-route and a second sub-route. The second route includes a third sub-route and a fourth sub-route. The first, second, third, and fourth sub-routes are different from each other.
