Claim Text:
1. A display device comprising: a panel in which a pixel is formed in each of a plurality of intersection areas between a plurality of data lines and a plurality of gate lines; two or more data driver integrated circuits (ICs) supplying data voltages to the plurality of data lines; a gate driver outputting a scan signal to the plurality of gate lines; a timing controller driving the data driver ICs and the gate driver; and a plurality of gamma voltage generators generating gamma voltages respectively provided to the data driver ICs, wherein each of the data driver ICs generates data voltages by using gamma voltages generated by itself and gamma voltages shared from another data driver IC of the two or more data driver ICs, wherein the two or more data driver ICs include a first data driver IC and a second data driver IC, and the plurality of gamma voltage generators include a first gamma voltage generator and a second gamma voltage generator, and wherein a first digital to analog converter (DAC) included in the first data driver IC generates the data voltages by using gamma voltages of a first color and a first portion of gamma voltages of a second color generated by the first gamma voltage generator included in the first data driver IC, and a second portion of gamma voltages of the second color and gamma voltages of a third color transferred to the first data driver IC from the second data driver IC.
