description	The present disclosure relates to a video wall. The video wall according to an embodiment of the present disclosure comprises: a plurality of displays; an image divider configured to divide an input image into a plurality of images; and at least one controller, wherein in response to a video being repeatedly played back, the at least one controller is configured to calculate an accumulated luminance value for each block on the plurality of displays during a first period when the video is repeatedly played back and calculate a luminance compensation value for each block based on the calculated accumulated luminance, and the plurality of displays display the video based on the luminance compensation value during a second period following the first period. Accordingly, an afterimage occurring due to the repeatedly played video may be reduced.
