5. A gate driving circuit, comprising a plurality of cascaded gate driving modules, wherein one of the gate driving modules comprises:
a gate driving sub-module comprising a first output node and a pull-down node, wherein the first output node is used to output a first driving signal; and
an in-phase output sub-module comprising a first control node, a second control node, and a second output node, wherein the first control node is electrically connected to the first output node, and the second control node is electrically connected to the pull-down node, the second output node is used to output a second driving signal, and a phase of the second driving signal is same as a phase of the first driving signal, wherein the one of the gate driving modules further comprises:
a first wire electrically connected to the gate driving sub-module for transmitting a first constant voltage low potential signal;
a second wire electrically connected to the in-phase output sub-module for transmitting a second constant voltage low potential signal;
a third wire electrically connected to the gate driving sub-module for transmitting a first constant voltage high potential signal; and
a fourth wire electrically connected to the in-phase output sub-module for transmitting a second constant voltage high potential signal.
