1. A display device, comprising:
a display;
an illuminance sensor;
an IR sensor disposed at a lower side of the display device, the IR sensor comprising a light emitting device and a light receiving device;
a memory to store correction data set by respective reflectance; and
a processor configured to:
calculate a reflectance of a floor surface, in an environment in which the display device is arranged, based on light projected from the light emitting device to the floor surface and light incident to the light receiving device,
obtain correction data corresponding to the calculated reflectance from stored correction data in the memory,
correct an illuminance value obtained from sensing by the illuminance sensor according to a correction parameter corresponding to the calculated reflectance in the obtained correction data, and
control an operation of the display based on the corrected illuminance value.
