ABSTRACT:
A control circuit for a common line is provided. The control circuit is connected to each of common lines of a liquid crystal display. The control circuit modulates the voltage of each individual common line. The control circuit controls the switching time of the common line according to a pass pulse, and switches the voltage of the common line according to two switching signals. The two switching signals have opposite logic levels in the same frame time.
