Abstract

A data driver includes a first latch that provides a first color grayscale in a first voltage range; a first level shifter that converts the first color grayscale in the first voltage range into a first color grayscale in a second voltage range greater than the first voltage range; a first decoder that generates a first gate control signal in the second voltage range based on the first color grayscale in the second voltage range; and a first digital-to-analog converter that provides a first gamma voltage of the first color grayscale based on the first gate control signal in the second voltage range.
