Abstract
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.
