Abstract: A scan driver sequentially activates scan lines of a display apparatus having m-number of scan lines. The scan driver includes a pull-up driving section and a pull-down driving section. The pull-up driving section includes a pull-up transistor that is electrically connected to an ith scan line to activate the ith scan line to be in a high level state. The pull-down driving section includes a pull-down transistor that is electrically connected to the ith scan line to inactivate the ith scan line to be in a low level state when (i+1)th scan line is activated. A gate electrode of the pull-up transistor is electrically separated from the ith scan line. The above ‘m’ is an integer greater than 1, and ‘i’ is an integer no greater than ‘m’. Therefore, display defects may be minimized, and detecting a cause of the display defect may be simplified to enhance productivity.

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.
