Patent ID: 8179345

Claim:
A source driver comprising: a first source line driver circuit that is operable to receive first color data and to control color of a first cell that corresponds to the first source line driver circuit; and a second source line driver circuit that is operable to receive second color data and to control color of a second cell that corresponds to the second source line driver circuit, wherein first through n th buffer amplifiers are installed in the first source line driver circuit, and n+1 th through 2n th buffer amplifiers are installed in the second source line driver circuit, wherein ones of the first through 2n th buffer amplifiers are turned on and remaining ones of the first through 2n th buffer amplifiers are turned off when the first color data is equivalent to the second color data, and wherein the ones of the first through 2n th buffer amplifiers that are turned on simultaneously control the colors of the cells corresponding to the first source line driver circuit and the second source line driver circuit.
