Abstract:
A gate driving circuit and a display panel are disclosed. A pull-up control module and a pull-down module of each stage gate driving unit are connected to a first node. A thin film transistor in the pull-up control module and/or pull-down module that is connected to the first node is an oxide thin film transistor, such that a leakage current of the first node is reduced due to the advantage of the small off-state leakage current of the oxide thin film transistor. Therefore, the voltage level of the first node can remain stable during a pull-up stage and a touch suspension stage.
