Patent ID: 8643582

Claim:
A driving apparatus of a liquid crystal display, the driving apparatus comprising: a plurality of data driving integrated circuits, wherein a clock signal, a plurality of data signals and a first reference voltage are transmitted to the data driving integrated circuits from the 1st data driving integrated circuit to the last data driving integrated circuit in series; and a control board for providing the clock signal, the data signals and the first reference voltage, wherein the control board changes the first reference voltage received by each of the data driving integrated circuits in operation according to a variation of the clock signal and the data signals transmitted between the data driving integrated circuits, wherein an attenuation status of the first reference voltage transmitted between the data driving integrated circuits is substantially identical to an attenuation status of the clock signal and the data signals transmitted between the data driving integrated circuits, wherein an operation frequency of each of the data driving integrated circuits is not restricted by an attenuation of the clock signal and the data signals transmitted between the data driving integrated circuits.
