Abstract
A scan driver drives a display device having a plurality of gate lines transferring scan signals, and a plurality of source lines transferring data signals. The scan driver includes a shift register and a multiple signal applying unit. The shift register includes a plurality of cascade-connected stages, each stage having an output terminal electrically connected to a respective one of the plurality of gate lines. The multiple signal applying unit applies a sub scan signal and a main scan signal. The sub scan signal and the main scan signal sequentially activate each of the plurality of gate lines. Therefore, the scan lines receive the scan signal twice, so that the liquid crystal capacitors electrically connected to the gate lines receive the data voltage twice. As a result, even though the time for charging the liquid crystal capacitors may be reduced, the liquid crystal capacitors may be fully charged to enhance display quality.
