  • Patent number: 7880503
    Abstract: A method of driving gate lines is used to activate the gate lines by outputting output signals of stages to the gate lines. A first node is boosted up based upon a carry signal or the vertical start signal from a previous stage. A gate signal that is pulled up is outputted through an output terminal of a present stage based upon a first clock signal which is boosted up. An off-voltage is outputted through the output terminal of the present stage in response to an output signal from a next stage or the vertical start signal. The first node is discharged in response to the output signal from the next stage or a carry signal from a last stage. A positive ripple voltage at the first node is removed by providing a negative ripple voltage to the first node.
