1. A display device, comprising:
a display panel that includes pixels each displaying one of a red, a green, and a blue;
a controller that generates an output grayscale value based on an input grayscale value, a remapped grayscale value corresponding to the input grayscale value, and a gain value calculated based on a measured luminance of the display panel corresponding to a specific grayscale; and
a data driver that generates a data signal based on the output grayscale value and provides the data signal to each of the pixels,
wherein
the output grayscale value is calculated by Equation 1:

OG Complex Work Unit Math
where the GRAY_OUT is the output grayscale value, the GRAY_IN is the input grayscale value, the GRAY_RE is the remapped grayscale value, and the GV is the gain value, and a grayscale range of the remapped grayscale value is included in a grayscale range of the input grayscale value.
