Abstract
A data driver includes a gamma unit, a digital-to-analog converter, and an output buffer. The gamma unit receives at least one reference voltage, and generates a first gamma reference voltage corresponding to a first sub-pixel and a second gamma reference voltage corresponding to a second sub-pixel using the received at least one reference voltage. The digital-to-analog converter receives the first and second gamma reference voltages from the gamma unit, and generates a first gamma data value corresponding to the first sub-pixel using the first gamma reference voltage and a second gamma data value corresponding to the second sub-pixel using the second gamma reference voltage. The output buffer outputs a first frame including the first gamma data value and a second frame including the second gamma data value. The output buffer outputs the first and second frames in a repeated manner for every predetermined number of frames.
