1. A tiled display device comprising:
a first display device and a second display device, the first display device and the second display device each including a display area including pixels and a non-display area adjacent to the display area;
a coupling area disposed between the first display device and the second display device;
a viewing distance detector detecting a viewing distance between the tiled display device and a user; and
a luminance compensator that compensates luminance of the pixels adjacent to the coupling area based on a size of the coupling area and the viewing distance, wherein
the luminance compensator calculates a visibility index based on the size of the coupling area and the viewing distance, and
the luminance compensator determines a luminance compensation amount for optimizing the visibility index relative to a reference index at which the coupling area is not recognized by the user,
in case that the luminance compensation amount has a specific value, the luminance compensator calculates a visibility index that changes depending on the viewing distance,
the luminance compensator determines a range of the viewing distance in which the visibility index satisfies the reference index, the luminance compensator determines the luminance compensation amount based on a selection of the user within the range of the viewing distance in which the visibility index satisfies the reference index, and
the luminance compensator increases a number of the pixels of which the luminance is to be compensated in case that a luminance compensation amount increases.
