Patent ID: 7106291

Claim:
A method of driving a liquid crystal display having a plurality of liquid crystal cells arranged in a matrix type, said method comprising the steps of: providing a gate driver for receiving a gate voltage from a pulse voltage generator, a gate start pulse and a gate output enable signal to generate at least one gate pulse having a desired falling slope; applying video signals to a plurality of data lines connected to the liquid crystal cells; and sequentially applying the at least one gate pulse having the desired falling slope to a plurality of gate lines connected to the liquid crystal cells in a direction crossing the data lines, wherein the pulse voltage generator is directly connected to a first switching device of the gate driver, and wherein the pulse voltage generator includes: first and second resistors connected, in series, between an input terminal supplied with a gate shift clock signal and a ground voltage source, a first transistor commonly connected to the first and second resistors; third and fourth resistors connected,in series, between the first transistor and a first voltage source; a second transistor commonly connected to the third and fourth resistors; a third transistor connected to the first transistor; fifth and sixth resistors connected, in series, between the third transistor and the first voltage source; an eighth resistor commonly connected to the fifth and sixth resistors; a seventh resistor connected between a fourth transistor and the second transistor; a ninth resistor provided between the second transistor and the ground voltage source; and an output terminal connected to the ninth resistor.
