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.

Abstract: A display device includes pixels, an image converter generating second image data using first image data of an N-th frame and first image data of an (N+1)th frame; and a data driver supplying a data signal corresponding to the second image data to the pixels during an (N+1)th frame period. The image converter detects a logo and a logo area using the first image data, calculates a first representative value of data corresponding to a peripheral area of the logo area among the first image data of an N-th frame and a second representative value of data corresponding to a reference area among the first image data of the (N+1)th frame, and selectively converts data for the logo among the first image data of the (N+1)th frame according to the first representative value and the second representative value to generate the second image data of the (N+1)th frame.

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.
