Patent ID: 8305324

Claim:
A scan driver driving a display device having a plurality of gate lines transferring scan signals, and a plurality of source lines transferring data signals, the scan driver comprising: a shift register including a plurality of cascade-connected stages, each stage of the shift register having an output terminal immediately connected to a respective one of the plurality of gate lines; and a multiple signal applying unit which applies a sub scan signal and a main scan signal to the plurality of gate lines through the shift register, the sub scan signal and the main scan signal sequentially activating the plurality of gate lines, wherein the multiple signal applying unit comprises an ending part including at least ‘I’ number of stages, and a first stage of the ending part is cascade-connected to a last stage of the shift register, wherein ‘I’ represents a natural number equal to or greater than two, wherein the at least ‘I’ number of stages of the ending part are sequentially disposed in proximity to one another, wherein all of the at least ‘I’ number of stages of the ending part are separated from the plurality of gate lines, so that none of the at least ‘I’ number of stages of the ending part is connected to the plurality of gate lines, and wherein an output of a stage of the at least ‘I’ number of stages of the ending part is inputted to a successive stage of the at least ‘I’ number of stages of the ending part.
