Abstract
A display device includes a signal receiver configured to receive an image signal; a display including a plurality of modules each including a plurality of light sources, and display an image based on the received image signal; and a controller configured to perform first uniformity calibration between light sources within each individual module with regard to the modules, and second uniformity calibration between the modules, wherein the controller controls the first uniformity calibration to be applied to the image signal received in the signal receiver based on a first coefficient determined for each of the light sources within each individual module, controls the second uniformity calibration to be applied to the image signal subjected to the first uniformity calibration based on a second coefficient determined for each of the modules, and controls a calibrated image to be displayed based on the image signal subjected to the second uniformity calibration.
