1. a shift register is characterized in that, described shift register comprises multistage, { S n, n=1,2 ..., N, N are a positive integer, wherein each described level comprises:

  • One first input end (IN1) is in order to receive the signal in one first clock signal (CK1) and one second clock signal (XCK1);

    One second input end (IN2), when receiving described the first clock signal (CK1) when described first input end, receive one the 3rd clock signal (CK2), when described first input end receives described the second clock signal (XCK1), receive one the 4th clock signal (XCK2);

    One the 3rd input end (IN3) is in order to receive a supply voltage (VSS);

    One four-input terminal (IN4);

    One the 5th input end (IN5);

    One the 6th input end (IN6);

    One the 7th input end (IN7);

    One the 8th input end (IN8);

    One first output terminal (OUT1) is in order to export an output signal (O n);

    One second output terminal (OUT2) is in order to export a drop-down signal (K n);

    One pull-up circuit is electrically coupled between described first input end (IN1) and described the first output terminal (OUT1);

    Draw control circuit to be electrically coupled between described the 5th input end (IN5) and the described pull-up circuit on one;

    The described pull-up circuit of one first pull-down circuit electric property coupling;

    Described the second input end of one first pull-down control circuit electric property coupling (IN2), described the second output terminal (OUT2) and described the first pull-down circuit;

    The one second described four-input terminal of pull-down circuit electric property coupling (IN4), described the first pull-down control circuit and described pull-up circuit;

    AndDescribed the 6th input end of one the 3rd pull-down circuit electric property coupling (IN6), described the second pull-down circuit and described pull-up circuit,Wherein because described these multistage { S nSerial electric property coupling, therefore n level S nIn four-input terminal (IN4) electric property coupling n-1 level S N-1The second output terminal (OUT2), in order to therefrom to receive corresponding drop-down output signal (K N-1), or electric property coupling n+1 level S N+1, in order to therefrom to receive corresponding drop-down output signal (K N+1);

    Described n level S nIn the described n-1 level of the 5th input end (IN5) electric property coupling S N-1The first output terminal, in order to therefrom to receive corresponding output signal (O N-1);

    Described n level S nIn the described n+1 level of the 6th input end (IN6) electric property coupling S N+1The first output terminal, in order to therefrom to receive corresponding output signal (O N+1);

    Described n level S nIn the 7th input end (IN7) electric property coupling n+2 level S N+2The first output terminal, in order to therefrom to receive corresponding output signal (O N+2);

    Described n level S nIn the 8th input end (IN8) electric property coupling n-2 level S N-2The first output terminal, in order to therefrom to receive corresponding output signal (O N-2).
