ABSTRACT:
A shift register has shift register units. The nthshift register unit includes first to third level control units and first and second driving units. The first and second level control units respectively provide a first clock signal and a first voltage to an output terminal. The first driving unit and the first level control unit are coupled to a first node, and a voltage on the first node is a first control signal. The first driving unit turns on and off the first level control unit in response to an input signal and second and third control signals. The second driving unit turns on and off the second level control unit in response to the first control signal. The third level control unit provides the first voltage to the output terminal in response to a front edge of the first control signal of the (n+2)thshift register unit.
