1. A scanning driving circuit, the scanning driving circuit comprising a first driving circuit and a second driving circuit, each of the first driving circuit and each of the second driving circuit comprising a plurality of driving unit in cascade connections, and each of the driving unit comprising:

  • a forward and reverse scanning module to output a forward scanning signal, a reverse scanning signal and an optional signal;

    a pull-down maintain module connected to the forward and reverse scanning module and to receive the optional signal from the forward and reverse scanning module and output a pull down signal according to the optional signal;

    a control module connected to the forward and reverse scanning module and the pull-down maintain module, and to receive the forward scanning signal and the reverse scanning signal from the forward and reverse scanning module and the pull down signal from the pull-down maintain module then output a high electrical level or a low electrical level scanning driving signal;

    a scanning line to transmit the scanning driving signal to the pixel unit; and

    a reset module connected to the pull-down maintain module and the control module to reset the electrical potential of the scanning line.
