Claim 9:
10. A control method for a display device including a display panel, the display panel including a plurality of display modules, the method comprising:
controlling the display panel to display a test image;
while the test image is being displayed, receiving position information and a corrected pixel value of a first area in a first display module among the plurality of display modules from an external electronic device and receiving position information and a corrected pixel value of a second area in the first display module other than the first area;
based on the received position information, identifying at least one pixel corresponding to the first area in the first display module and identifying at least one pixel corresponding to the second area in the first display module other than the first area;
obtaining a correction coefficient corresponding to the at least one pixel based on the received corrected pixel value and an output pixel value of the identified at least one pixel corresponding to the first area and obtaining a correction coefficient corresponding to the at least one pixel corresponding to the second area other than the first area;
obtaining correction coefficients corresponding to each of a plurality of remaining pixels in the first display module based on the obtained correction coefficient and a distance between the respective remaining pixels and the identified at least one pixel;
storing the correction coefficients;
processing an input image based on the stored correction coefficients; and
displaying the processed input image,
wherein the obtaining of the correction coefficients corresponding to each of the plurality of remaining pixels comprises:
obtaining correction coefficients corresponding to each of the plurality of remaining pixels based on the correction coefficient corresponding to the at least one pixel corresponding to the first area and the correction coefficient corresponding to the at least one pixel corresponding to the second area.
