Abstract
A shift register includes a first scan unit including a first input circuit and a first output circuit, and a second scan unit including a second input circuit, a second output circuit, and a fourth transistor. The first input circuit is electrically connected to an input signal terminal and a first pull-up node. The first output circuit is electrically connected to the first pull-up node, a first clock signal terminal, a second clock signal terminal, a shift signal terminal, and a first scan signal terminal. The second input circuit is electrically connected to the input signal terminal and a second pull-up node. The second output circuit is electrically connected to the second pull-up node, a third clock signal terminal, and a second scan signal terminal. The fourth transistor is electrically connected to the second pull-up node, a sub-clock signal terminal, and a dummy shift signal terminal.
