1. A line scanning unit, comprising:
an input module, configured to pull-up a voltage of a first node to be at high potential according to a (N−1)th transmission signal; the N being an integer greater than 1;
an output module, configured to receive a first clock signal and output an output signal via a signal output terminal in response to the voltage of the first node being at high potential;
a pull-down maintenance control module, configured to pull-up a voltage of a second node to be at high potential;
a maintaining module, configured to pull-down a voltage of the signal output terminal and the voltage of the first node to be at low potential in response to the voltage of the second node being at high potential;
a pull-down module, configured to pull-down the voltage of the second node to be at low potential;
a first reset module, configured to pull-down the voltage of the first node to be at low potential according to a (N+2)th transmission signal;
a second reset module, configured to pull-down the voltage of the first node, the voltage of the second node, and the voltage of the signal output terminal to be at low potential according to a second clock signal.
