Abstract: A display device according to an embodiment includes a plurality of display panels arranged adjacent to each other and each display panel including first pixels in the display panel and second pixels in the display panel and adjacent to a boundary area of the display panels, and a luminance correction unit configured to generate a correction grayscale value for the second pixel. The luminance correction unit includes an image mapping unit configured to map a captured luminance image to a unit pixel image, a de-blurring unit configured to perform a de-blurring operation on the mapped unit pixel image to calculate a correction luminance value for the second pixel, and a correction unit configured to calculate a correction grayscale value for the second pixel corresponding to the calculated correction luminance value of the second pixel.

Abstract: A controller includes a bit shifter and a stain compensator. The bit shifter may determine a bit shift value corresponding to a stain compensation value according to an area of a display panel. The bit shift value represents a quantity of integer bits and a quantity of decimal bits. At least one of the quantity of integer bits and the quantity of decimal bits corresponds to a quantity of stain compensation steps. The stain compensator may compensate a grayscale value of input image data using the stain compensation value and the bit shift value to generate compensated image data.
