    Abstract: A display device includes pixels; an image converter which generates a second image by correcting grayscales of a logo among a first image for the pixels; and a data driver which provides data voltages corresponding to the second image to the pixels. The image converter generates first accumulated data by accumulating first map data corresponding to a logo area larger than the logo among the first image during a plurality of frame periods, generates second accumulated data by scaling the first accumulated data every refresh cycle, generates third accumulated data by initializing values smaller than a first threshold value among the second accumulated data to be a background value, and specifies pixels corresponding to the logo based on second map data corresponding to the third accumulated data.

    Abstract: A display device includes a display panel, a controller, and a data driver. The display panel includes a plurality of pixels. The controller is configured to: receive input image data for the display panel; divide the display panel into a plurality of first pixel blocks each having a first size; divide the display panel into a plurality of second pixel blocks each having a second size different from the first size; generate, based on the input image data, a first stress map for the plurality of first pixel blocks and a second stress map for the plurality of second pixel blocks; and generate output image data by compensating the input image data based on the first stress map and the second stress map. The data driver is configured to provide data voltages to the plurality of pixels based on the output image data.

    Abstract: A display device includes: pixels arranged in a display area; a timing controller which generates image data of each frame based on an input image signal of the each frame, the timing controller including a logo controller which detects a logo image and a logo area including the logo image from the input image signal of the each frame to control luminance of the logo image; and a data driver which generates a data signal based on the image data and supplies the data signal to the pixels. The logo controller generates a first logo map based on an input image signal of a previous frame, generates a second logo map based on an input image signal of a current frame, and determines a similarity between the first logo map and the second logo map to selectively change luminance of a logo image of a next frame.
