1. a shift register cell, is characterized in that, comprising:

  • input block, output unit, pull-up unit, drop-down control unit and drop-down unit, wherein,Described input block, connect input signal end, in response to input signal, input signal is supplied to output unit by first node, described first node is the tie point of described input block and described output unit;

    Described output unit, for the voltage in response to described first node, and is supplied to lead-out terminal by the first clock signal;

    Described pull-up unit, for the voltage in response to described first node, is supplied to first node by the first clock signal;

    Described pull-up unit is the 3rd thin film transistor (TFT), and its grid is connected first node with source electrode simultaneously, drain electrode connection first clock signal;

    Described drop-down control unit, for responding the first clock signal and second clock signal, using the first clock signal and second clock signal by being supplied to drop-down unit as the Section Point of described drop-down control unit output terminal;

    And in response to the voltage of first node, power cathode voltage is supplied to Section Point, and described Section Point is the tie point of described drop-down control unit and described drop-down unit;

    Described drop-down unit, for responding the voltage of described Section Point, provides power cathode voltage to first node and lead-out terminal.
