ABSTRACT:
A shift register includes a plurality of electrically connected shift units. Each shift unit includes a pull-up circuit, a pull-up driving circuit, a pull-down circuit, and a pull-down driving circuit. The pull-up circuit outputs a first signal to an output node according to the first signal and a voltage of a driving node. The pull-up driving drives the pull-up circuit according to an output voltage of the previous shift unit. The pull-down driving circuit outputs a low level voltage to the driving node and the output node according to the first signal and a second signal. The pull-down circuit resets the pull-up driving circuit according to the voltage of the output node and outputs the low level voltage to the output node and the driving node according to a third signal and a fourth signal.
