Abstract
A shift register includes a first switch and a second switch coupled to a first node, a pull-down circuit selectively connecting the first node to a voltage end according to a potential of a second node, a control circuit, and an input stage circuit which may receive a previous-stage shift register output signal, a next-stage shift register output signal, and at least one scanning order logic signal. The first switch receives clock signals. A first output end of the input stage circuit outputs the previous-stage shift register output signal or the next-stage shift register output signal to a control end of the second switch based on the scanning order logic signal. The previous-stage shift register output signal or the next-stage shift register output signal triggers a second output end of the input stage circuit to output the scanning order logic signal to an input end of the control circuit.
