Patent ID: 8378949

Claim:
A driving apparatus for use in a liquid crystal display, comprising: a plurality of data driving integrated circuits, wherein a clock signal, a plurality of data signals, a first reference voltage and a second reference voltage are simultaneously transmitted to the data driving integrated circuits from the 1 st data driving integrated circuit to the last data driving integrated circuit in series, wherein the first reference voltage is different from the second reference voltage; and a control board for providing the clock signal, the data signals, the first reference voltage and the second reference voltage, wherein the control board respectively determines each of the data driving integrated circuits to only receive either the first reference voltage or the second reference voltage in operation according to a variation of the clock signal and the data signals transmitted between the data driving integrated circuits, such that an i th data driving integrated circuit and an (i+1) th data driving integrated circuit of the plurality of data driving integrated circuits respectively receive the first reference voltage and the second reference voltage simultaneously in operation when the variation of the clock signal and the data signals transmitted between the data driving integrated circuits exceeds a predetermined value, where i is a positive integer, wherein the i th data driving integrated circuit and the (i+1) th data driving integrated circuit receive the same first reference voltage or the same second reference voltage in operation when the variation does not exceed the predetermined value.
