Claim 19:
20. A display device comprising:
a memory storing one or more instructions, and
a processor configured to execute the one or more instructions to:
selectively drive a first light source or a second light source among a plurality of light sources;
control a spatial light modulator to modulate the light from the first light source or the second light source to form an image light;
based on the first light source being driven, control a first mirror cell corresponding to the first light source, among a plurality of mirror cells of a micro mirror array, to be in an ON state in which light incident on the first mirror cell is reflected in a first direction toward a first position that is inside of an eye box, and control a second mirror cell, among a plurality of mirror cells, to be in an OFF state in which light incident on the second mirror is reflected in a second direction toward a second 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 a third 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,
wherein the micro mirror array being arranged in an optical path formed in a focusing optical system that focuses the image light formed by the spatial light modulator at the first position or the third position in the eye box.
