Abstract
An exemplary shift register () includes a plurality of shift register units () connected one by one. Each of the shift register units includes a first switch unit (), a second switch unit (), a third switch unit (), a fourth switch unit (), and a fifth switch unit (). A signal input terminal of each shift register unit is coupled to an output terminal of a rear-stage shift register unit. A first clock input terminal receives a first clock signal to turn on/off the first and second switch units. The third switch unit receives a second clock signal. The fourth switch unit pulls up the output voltage of the output terminal according to a controlling signal from the first switch unit. The fifth switch unit pulls down the output voltage of the output terminal according to controlling signals from the second and third switch units.
