Abstract
Provided are a shift register unit, a shift register, a display panel and a driving method thereof. The shift register unit includes: an input circuit electrically coupled to an input terminal, a first voltage terminal and a pull-up node; an output circuit electrically coupled to the pull-up node, a first clock terminal, a first scan control terminal, a first output terminal and a second output terminal; and a scan control circuit electrically coupled to the second output terminal, a second voltage terminal and a second scan control terminal. The input circuit is configured to write a first voltage provided by the first voltage terminal into the pull-up node in response to a start signal inputted to the input terminal. The output circuit is configured to output a first clock signal from the first clock terminal via the first output terminal, when the pull-up node is at the first voltage.
