1. A display device comprising:
a processor outputting an input frame;
a stereo frame generator generating a first frame and a second frame based on the input frame;
a first sub-display device displaying a first image based on the first frame; and
a second sub-display device displaying a second image based on the second frame,
wherein a first color gamut of the first frame is different from a second color gamut of the second frame, and
wherein the stereo frame generator includes:
an image separation unit generating a first separation frame that includes first grayscales for a first color of the input frame and generating a second separation frame that includes second grayscales for a second color of the input frame and third grayscales for a third color of the input frame, and
wherein the image separation unit assign arbitrary values to the second grayscales for the second color and the third grayscales for the third color of the first separation frame, and
wherein the image separation unit assign arbitrary values to the first grayscales for the first color of the second separation frame.
