Shift register and method for driving the same, gate driving circuit, and display device

A shift register comprising:

• a first scan unit, wherein the first scan unit comprises a first input circuit and a first output circuit, wherein
• the first input circuit is electrically connected to an input signal terminal, a first pull-up node and a second leakage prevention node;
• and
• 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;
• a second scan unit, wherein the second scan unit comprises a second input circuit and a second output circuit, wherein
• the second input circuit is electrically connected to a third leakage prevention node and a second pull-up node;
• and
• the second output circuit is electrically connected to the second pull-up node, a third clock signal terminal and a second scan signal terminal;
• and
• a blanking input unit electrically connected to a selection control signal terminal, the input signal terminal, a fourth clock signal terminal, the first pull-up node and the second pull-up node.
