Abstract
The present disclosure relates to a bidirectional shift register unit, a bidirectional shift register, and a display panel, wherein the bidirectional shift register unit includes: an pull-up circuit is configured to transform first clock signals into scanning signals outputting at a current level, an pull-up control circuit is configured with a forward pull-up sub-circuit and a backward pull-up sub-circuit respectively configured to pull up a potential of a control end of the pull-up circuit when a forward scanning process or a backward scanning process is conducted, a pull-down circuit and a pull-down maintaining circuit are respectively configured to pull down and continuously pull down the potential of the control end of the pull-up circuit and the scanning signals outputting at the current level during a pull-down phase. As such, a bidirectional scanning process may be achieved.
