    Abstract: A driver integrated circuit (IC) chip includes gamma voltage generators, a line selector, and a data driver. The gamma voltage generators generate gamma voltage sets based on a reference voltage set. The line selector controls the connection between a plurality of voltage line sets for providing the reference voltage set and the gamma voltage generators based on a selection signal. The data driver converts input image data to data signals based on the gamma voltage sets.
