Shift register and corresponding driving method, gate driving circuit and display device

A shift register, comprising:

• an input and reset circuit connected to an input terminal, a pull-up node and a reset terminal, and configured to set a potential at the pull-up node to an operating potential when a potential at the input terminal is the operating potential, and set the potential at the pull-up node to a reset potential when a potential at the reset terminal is the operating potential;
• a first output circuit connected to the pull-up node, a first control signal terminal and a first output terminal, and configured to output a first gate driving signal at the first output terminal when the potential at the pull-up node and a potential at the first control signal terminal are the operating potential;
• a second output circuit connected to the pull-up node, a second control signal terminal and a second output terminal, and configured to output a second gate driving signal at the second output terminal when the potential at the pull-up node and a potential at the second control signal terminal are the operating potential;
• a first pull-down circuit connected to a first pull-down node, the pull-up node, the first output terminal and the second output terminal, and configured to set the potentials at the pull-up node, the first output terminal and the second output terminal to the reset potential when a potential at the first pull-down node is the operating potential;
• a second pull-down circuit connected to a second pull-down node, the pull-up node, the first output terminal and the second output terminal, and configured to set the potentials at the pull-up node, the first output terminal and the second output terminal to the reset potential when a potential at the second pull-down node is the operating potential;
