Gate driving circuits, display panels, and display devices are provided. The gate driving circuit includes cascaded gate driving units, each of which includes an input unit, an output unit, a reset control unit, and a pull-down holding unit. The input unit outputs a driving signal to a first node. The output unit outputs a scanning signal in response to the driving signal. The reset control unit outputs a reset control signal to a second node during a first period. The pull-down holding unit receives the reset control signal. The pull-down holding unit outputs a first voltage signal to the first node in response to the reset control signal to reset a potential of the first node during the first period, and outputs the first voltage signal to the first node to maintain the potential of the first node during a second period.

Gate driving circuits, display panels and display devices

A gate driving circuit including cascaded gate driving units is provided. A gate driving unit includes a pull-up control module, a pull-up module electrically connected to the pull-up control module through a first node, a pull-down maintaining module electrically connected to the first node and a voltage line, and a voltage control module. An input terminal of the pull-up module loads a clock signal, and an output terminal is electrically connected to a gate line. The pull-down maintaining module is electrically connected to the pull-up module through the first node and includes an inverter module. The voltage control module is electrically connected to an output terminal of the inverter module to control a first transition edge of a signal at the output terminal of the inverter module to lag behind a second transition edge of the clock signal within a duration of a corresponding clock pulse of the clock signal.
