1. A shift register unit, comprising:
a sensing control circuit connected to a first sensing signal input terminal, a second sensing signal input terminal, and a sensing control node, and configured to write an active level signal provided by the second sensing signal input terminal to the sensing control node in response to control of an active level signal provided by the first sensing signal input terminal;
a first sensing input circuit connected to a first level supply terminal, a first clock control signal input terminal, the sensing control node, and a first pull-up back node, and configured to write an active level signal provided by the first level supply terminal to the first pull-up back node in response to control of an active level signal at the sensing control node and an active level signal provided by the first clock control signal input terminal;
a first display input circuit connected to a display signal input terminal, a third power supply terminal, and a first pull-up node, and configured to write an active level signal provided by the third power supply terminal to the first pull-up node in response to control of an active level signal provided by the display signal input terminal;
a first switch circuit connected in series between the first pull-up node and the first pull-up back node, connected to a switch signal input terminal, and configured to control connection and disconnection between the first pull-up node and the first pull-up back node in response to control of a signal provided by the switch signal input terminal; and
a first driving output circuit connected to the first pull-up back node, a first driving clock signal input terminal, and a first driving signal output terminal, and configured to write a signal provided by the first driving clock signal input terminal to the first driving signal output terminal in response to control of an active level signal at the first pull-up back node.
