Each stage of shift register circuit includes a first switch, an input circuit, a pull-down circuit, and a pull-down voltage regulator circuit. The first switch is used to output a scan signal according to a voltage level of a node and a clock signal. The input circuit is used to pull up the voltage level of the node according to a signal from a previous M-th stage of shift register circuit. The pull-down circuit is used to pull down the voltage level of the node according to the clock signal and a signal from a following L-th shift register circuit and reduce current leakage at the node. The pull-down voltage regulator circuit is used to pull down the voltage levels of the node and the scan signal according to the voltage level of the node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shift register and method of driving shift register","description":"A shift register includes a plurality of stages of shift register circuit.
