Abstract

A gate driving circuit includes gate driving units. Each of the gate driving units includes a node voltage control module and a pull-down module. The node voltage control module includes a first module and a storage module. The first module outputs a first voltage signal at a first node in response to a pull-down control signal at a first control port. The storage module includes a first port receiving the first voltage signal, and a second terminal electrically connected to the first node. The pull-down module outputs a first working signal for controlling a plurality of sub-pixels to turn off at an output port of the gate driving unit in response to the first voltage signal. The storage module maintains the first voltage signal applied on the first node to maintain the first working signal at the output port of the gate driving unit controlled by the pull-down module.
