    Abstract: A display device includes pixels, an image converter which generates a second image by correcting grayscales of a first logo in a first image for the pixels, and a data driver which provides data signals corresponding to the second image to the pixels. The image converter detects the first logo based on value and saturation of the first image, generates first map data corresponding to the first logo, and specifies pixels corresponding to the first logo based on the first map 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.
