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: The present disclosure provides a display device with a display panel and driver. The driver includes a logo compensator to generate a logo map data with respect to a logo area through which the logo image is displayed and compensates for a brightness of the logo area using the logo map data. The logo compensator includes an extractor, a logo calculator, a logo determination unit, and a brightness compensation block. The extractor extracts logo area data. The logo calculator calculates the logo map data with first data corresponding to a first image recognized as the logo image and second data corresponding to a second image recognized as a logo background image. The logo determination unit sets a boundary area and determining whether a first area corresponding to the first image overlaps the boundary area to output determination data. The brightness compensation block compensates for the brightness of the logo area.
