Gate driving circuit, and array substrate and display panel using the same

An array substrate including a gate driving circuit, the gate driving circuit comprising a plurality of gate driving units, wherein each gate driving unit outputs a gate signal through a gate line coupled thereto, and each gate driving unit includes:

• an actuating unit configured to transmit an actuation signal;
• an energy storage unit coupled to an output end of the actuating unit to receive the actuation signal, and configured to execute a charging process under the action of the actuation signal and output a driving voltage;
• a pull-up unit coupled between the output end of the energy storage unit and the gate line to receive the driving voltage, and configured to pull up a gate signal on the gate line under the action of the driving voltage and a time pulse signal;
• a first pull-down unit coupled to the energy storage unit and the gate line, and configured to pull the driving voltage and the gate signal down to a first reference voltage under the action of a first control signal;
• a second pull-down unit coupled to the energy storage unit and the gate line, and configured to pull the driving voltage and the gate signal down to the first reference voltage under the action of a second control signal;
• and
• a third pull-down unit coupled to the energy storage unit, and configured to pull the driving voltage down, under the action of a third control signal, to a second reference voltage lower than the first reference voltage.
