1. An electronic apparatus comprising:
a first display;
a second display;
a lens array provided between the first display and the second display;
a first polarization modulation array provided between the first display and the lens array;
a second polarization modulation array provided between the lens array and the second display;
a memory configured to store at least one instruction; and
at least one processor configured to execute the at least one instruction to:
identify a first area in the second display, the first area having a luminance lower than a reference luminance;
identify, to control a first luminance of the first area in the second display to be the reference luminance, a first polarization angle variation corresponding to a first area in the first polarization modulation array and a second polarization angle variation corresponding to a first area in the second polarization modulation array;
control the first polarization modulation array based on the first polarization angle variation; and
control the second polarization modulation array based on the second polarization angle variation.
