    IPC: G09G3/3275

    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: An image compensator includes: a shift path updater for updating a first preliminary shift direction of a fixed image included in an image in a preset first period according a first shift scenario, and updating a second preliminary shift direction of the fixed image in a preset second period according a second shift scenario; a shift direction determiner for correcting the first preliminary shift direction and the second preliminary shift direction respectively to a first target shift direction and a second target shift direction, based on a result obtained by comparing the first preliminary shift direction and the second preliminary shift direction; a first shift controller for performing a first image shift, based on the first target shift direction; and a second shift controller for performing a second image shift, based on the second target shift direction.

    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.

    IPC: G09G3/20

    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 plurality of first pixels connected to a first scan line; a plurality of second pixels connected to a second scan line; and a plurality of third pixels connected to a third scan line, wherein, from a position in a first frame period, an image portion displayed by the first pixels, the second pixels, and the third pixels, which are connected to first data lines, is shifted in a first direction, in a second frame period next to the first frame period, wherein an image portion displayed by the first pixels and the second pixels, which are connected to second data lines, is shifted in the first direction, in the second frame period, wherein an image portion displayed by the third pixels connected to the second data lines is shifted in a direction different from the first direction, in the second frame period.
