ABSTRACT:
A method for driving a liquid crystal display is provided. In the method, a first pre-charge voltage and a second pre-charge voltage are generated from an external voltage source separated from a data driving integrated circuit. A data line is pre-charged with the first pre-charge voltage during a first period. The data line is charged to reach a target value of a first data signal during a second period. The data line is pre-charged with the second pre-charge voltage during a third period. The data line is charged to reach a target value of a second data signal during a fourth period. A liquid crystal display device is capable of reducing the heating value of a driver that drives the data line.
