1. A display device comprising:
a light source array comprising a plurality of light sources;
a spatial light modulator configured to modulate light from the light source array to form image light;
a focusing optical system configured to focus the image light formed by the spatial light modulator at a first position or a second position in an eye box;
a micro mirror array arranged in an optical path formed in the focusing optical system and comprising a plurality of mirror cells including a first mirror cell and a second mirror cell; and
a processor configured to:
selectively drive a first light source or a second light source among the plurality of light sources;
control the spatial light modulator to modulate the light from the first light source or the second light source to form the image light;
based on the first light source being driven, control the first mirror cell corresponding to the first light source to be in an ON state in which light incident on the first mirror cell is reflected in a first direction toward the first position that is inside of the eye box, and control the second mirror cell to be in an OFF state in which light incident on the second mirror is reflected in a second direction toward a third position that is outside of the eye box, and
based on the second light source being driven, control the second mirror cell corresponding to the second light source to be in an ON state in which light incident on the second mirror cell is reflected in a third direction toward the second position that is inside of the eye box, and control the first mirror cell to be in an OFF state in which light incident on the first mirror is reflected in a fourth direction toward a fourth position that is outside of the eye box.
