Abstract: A tiled display device includes a plurality of display panels coupled to each other, where each of the plurality of display panels includes an edge region adjacent to a boundary line between the plurality of display panels, and a panel driver which multiplies input gray levels of input image data for the plurality of display panels by an adaptive gain, generates boundary compensated image data by adding boundary compensation gray levels to the input gray levels multiplied by the adaptive gain for the edge region, and drives the plurality of display panels based on the boundary compensated image data. The adaptive gain is gradually decreased over a plurality of frame periods in a case where a sum of each of the input gray levels for the edge region and a corresponding one of the boundary compensation gray levels exceeds a maximum gray level.

Abstract: A display device includes a display panel including a plurality of pixels and that displays an image in a display area, and a driving controller which receives an image signal, drives the plurality of pixels, where the driving controller includes a compensation unit, and the plurality of pixels include a first pixel disposed in a central area of the display area and a second pixel spaced apart from the central area by a preset distance, the compensation unit outputs compensation data for controlling luminance of the image, and the display panel displays the image, in which a first luminance of the first pixel is less than a second luminance of the second pixel with respect to a same luminance value, based on the compensation data.

Abstract: A method of displaying an image on a display panel includes displaying an image of a grayscale value A, imaging the image of the grayscale value A with a camera, displaying an image of a grayscale value B, imaging the image of the grayscale value B with the camera, determining a compensation parameter P of the grayscale value A for each pixel in the display panel using the imaged data of the grayscale value A, determining a representative value Q of probability distribution of the compensation parameters of the grayscale value A from the image of the grayscale value A, determining a representative value R of probability distribution of compensation parameters of the grayscale value B from the image of the grayscale value B and compensating an input image data for each pixel using the value P, the value Q and the value R.
