1. A display driver integrated circuit (IC), comprising:
a data line driver configured to drive a first data line connected with a first pixel of a display in response to output image data; and
a dithering circuit configured to receive a brightness value of the display, to calculate a first reference grayscale value corresponding to the brightness value using a first group of threshold grayscale values, to receive input image data with a first grayscale value, which corresponds to the first pixel, to compare the first grayscale value and the first reference grayscale value, and to generate the output image data having not the first grayscale value but an output grayscale value when the first grayscale value is smaller than the first reference grayscale value.
