Abstract
A shift register unit is provided to include a shift register circuit having a display input circuit and at least two driving output circuits for sequentially outputting display driving pulses; each driving output circuit is configured to write a signal from a driving clock signal input terminal to a driving signal output terminal under a control of an active-level signal at a pull-up node; the shift register circuit further includes a first and/or a second pull-up voltage-stabilizing circuit; the first pull-up voltage-stabilizing circuit is connected to the pull-up node and at least configured to maintain a voltage at the pull-up node unchanged during a first driving output circuit outputs the display driving pulse; and the second pull-up voltage-stabilizing circuit is connected to the pull-up node and at least configured to maintain the voltage at the pull-up node unchanged during a last driving output circuit outputs the display driving pulse.
