1. A gate driving circuit comprising:

  • a plurality of cascaded shift register units; and

    a control unit,wherein every two shift register units constitute a shift register set and are connected to two gate lines through the control unit,wherein the control unit controls the shift register units of each shift register set to supply drive signals to the two gate lines, andwherein the control unit comprises;

    a plurality of pairs of thin film transistors, wherein each of the shift register units of each shift register set is connected to the two gate lines through one pair of thin film transistors of the plurality of pairs of thin film transistors; and

    a first control line and a second control line for respectively controlling each pair of thin film transistors of the plurality of pairs of thin film transistors such that each pair of thin film transistors of the plurality of pairs of thin film transistors are respectively turned on and off so that the shift register units of each shift register set selectively supply the drive signals to the two gate lines.
