Abstract
A shift register includes a plurality of serially-coupled shift register units each including a first node, a second node, an input circuit, a pull-up circuit and a pull-down circuit. The shift register unit receives an input voltage at an input end, and provides an output voltage at an output end. The input circuit controls the signal transmission path between a first clock signal and the first node according to the input voltage. The pull-up circuit controls the signal transmission path between a second clock signal and the output end according to the voltage level of the first node. The voltage level of the first node or the output end is maintained according to the voltage level of the second node. The voltage level of the second node is maintained according to the first clock signal, the second clock signal and the voltage level of the first node.
