1. A display device comprising:
a display comprising a plurality of light emitting diodes (LEDs);
a memory storing at least one instruction; and
a processor configured to execute the at least one instruction,
wherein the processor, by executing the at least one instruction, is configured to:
obtain output data comprising second three-dimensional (3D) color information for a first color outputted by the plurality of LEDs by driving each of the plurality of LEDs based on input data including first 3D color information,
obtain first four-dimensional (4D) color information corresponding to the first 3D color information and second 4D color information corresponding to the second 3D color information,
obtain 4D correction coefficients, associated with each of the plurality of LEDs, to calibrate second color information to be output by the plurality of LEDs, based on the input data including the first 4D color information and the output data including the second 4D color information, and
based on receiving a first input to display an image, control the plurality of LEDs to output the second color information to be output by the plurality of LEDs based on the obtained 4D correction coefficients.
