Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a communicator;
a memory;
a display panel including a plurality of display modules; and
one or more processors configured to:
control the display panel to display a test image,
while the test image is being displayed, receive 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 through the communicator and receive 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, identify at least one pixel corresponding to the first area in the first display module and identify at least one pixel corresponding to the second area in the first display module other than the first area,
obtain a correction coefficient corresponding to the at least one pixel corresponding to the first area 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 obtain a correction coefficient corresponding to the at least one pixel corresponding to the second area in the first display module other than the first area,
obtain 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,
store the correction coefficients in the memory,
process an input image based on the stored correction coefficients, and
control the display panel to display the processed input image,
wherein the one or more processors are further configured to:
obtain the 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.
