Patent ID: 8866724

Claim:
A method of driving a plurality of scan lines by providing a display panel with a plurality of scan line driving signals from a gate driver including a shift register, the method comprising: receiving a scan start signal to generate a first scan line driving signal and lowering a voltage level of the first scan line driving signal so as to inactivate a first scan line in response to a second scan line driving signal; receiving one of previous scan line driving signals to generate an Nth scan line driving signal for activating an Nth scan line, N being a natural number in a range from two to a number of scan lines except for a last scan line; lowering a voltage level of the Nth scan line driving signal so as to inactivate the Nth scan line in response to one of next scan line driving signals; generating a last scan line driving signal from a last stage in response to one of previous scan line driving signals of the last scan line driving signal; generating a dummy output signal from a dummy stage in response to the last scan line driving signal; lowering a voltage level of the last scan line driving signal so as to inactivate the last scan line in response to the dummy output signal; and directly applying the scan start signal to the dummy stage to lower a fourth voltage level of the dummy output signal in response to the scan start signal.
