Abstract
A driving apparatus for a liquid crystal display (LCD) is provided. The driving apparatus includes a plurality of data driving ICs and a control board. The data driving ICs are used for receiving and transmitting a clock signal, a plurality of data signals and a first reference voltage from the 1st data driving IC to the last data driving IC in series. The control board is used for providing the clock signal, the data signals and the first reference voltage, and changing the first reference voltage received by each data driving IC according to a variation of the clock signal and the data signals transmitted between the data driving ICs, so that the operation frequency of the data driving ICs is unrestricted.
