Abstract: A luminance correction system includes: a display device that displays an image of a first grayscale value; an image capturing device that generates a first image and a second image by capturing the displayed image; and an image separator that generates a first high-frequency image by extracting a high-frequency image from the first image, and generates a second low-frequency image by extracting a low-frequency image from the second image, wherein the display device includes: an image corrector that generates a corrected image data by analyzing the first high-frequency image and the second low-frequency image to provide an analyzation result and by correcting an image data with respect to the displayed image in accordance with the analyzation result to generate the corrected image data; and a display unit including a plurality of pixels that emit light with luminance corresponding to the corrected image data.

Abstract: A display device according to an exemplary embodiment of the present invention includes: a display unit configured to display a specific image according to first data supplied from the outside; an image compensator configured to receive a photographed image in which the specific image is photographed and generate variation information corresponding to luminance variations of pixels using the photographed image; an image corrector configured to generate second data by correcting the first data according to the variation information; and a data driver configured to generate a data signal using the first data or the second data and supply the data signal to the display unit.

Abstract: Disclosed are a curved display device and a driving method therefor. The curved display device includes: a display panel including a curved portion and a flat portion; a luminance compensator configured to determine a first luminance compensating value for the flat portion and to determine a second luminance compensating value for one or more positions of the curved portion; and a signal controller for adjusting an input image signal corresponding to the first and second luminance compensating values set by the luminance compensator so as to compensate luminance of those portions of the input image signal corresponding to both the curved portion and the flat portion of the display panel, and for transmitting the compensated image signal to the display panel.

Abstract: Provided are a display device and a driving method thereof. The display device includes a display panel, a luminance compensator, and a signal controller. The display panel includes a first curved portion having a first curvature degree and a second curved portion having a second curvature degree different from the first curvature degree. The luminance compensator sets a first luminance compensation value corresponding to the first curved portion and sets the first luminance compensation value as a second luminance compensation value corresponding to the second curved portion. The signal controller compensates an input image signal input in response to the luminance compensation value set by the luminance compensator.
