1. A shift register unit, comprising:
a first shift register coupled to an input signal terminal, a first clock signal terminal and a second clock signal terminal, and configured to generate a first output signal based on a signal at the first clock signal terminal and generate a second output signal based on a signal at the second clock signal terminal under a control of a signal at the input signal terminal; and
a second shift register coupled to the input signal terminal and a third clock signal terminal, and configured to generate a third output signal based on a signal at the third clock signal terminal under the control of the signal at the input signal terminal;
wherein the first shift register comprises:
a first control circuit coupled to the input signal terminal and a reset signal terminal, and configured to control a potential at a pull-up node of the first shift register and a potential at a pull-down node of the first shift register according to a signal at the input signal terminal and a signal at the reset signal terminal;
a first output circuit coupled to the first clock signal terminal, the pull-up node of the first shift register, and the pull-down node of the first shift register, and configured to generate the first output signal based on the signal at the first clock signal terminal under a control of the potential at the pull-up node of the first shift register and the potential at the pull-down node of the first shift register; and
a second output circuit coupled to the second clock signal terminal, the pull-up node of the first shift register, and the pull-down node of the first shift register, and configured to generate the second output signal based on a signal at the second clock signal terminal under the control of the potential at the pull-up node of the first shift register and the potential at the pull-down node of the first shift register.
