Abstract:
A shift register has an input stage circuit, a first switch, a control circuit and a pull down circuit. A first end of the first switch receives a first clock signal. A second end and a control end of the first switch are respectively coupled to an output end of the shift register and a first output end of the input stage circuit. The control circuit controls electrical connection between a first power terminal and a node according to a second clock signal and controls electrical connection between the node and a second power terminal according to a voltage level of a second output end of the input stage circuit. The pull down circuit controls electrical connection between the second output end and the second power terminal and electrical connection between the output end and the second power terminal according to a voltage level of the node.

Abstract:
A shift register has a first switch, a pull-up circuit, and a pull-down circuit. The first switch receives a first clock signal. The pull-up circuit is configured to turn on the first switch to pull up a voltage level of an output terminal of the shift register. The pull-up circuit has a second switch and a first control circuit. The first control circuit is coupled to a first system power terminal to avoid an excessive voltage difference between two nodes of the first control circuit. The pull-down circuit is configured to pull down the voltage level of the output terminal of the shift register when the first switch is turned off, and further configured to keep a voltage level of a control node of a switch coupled between the output terminal and a second system power terminal at a low voltage.
