Gate driving circuit, and array substrate and display panel using the same
Abstract:
The present invention relates to a gate driving circuit, and a array substrate and a display using the same. The gate driving circuit comprises multiple-stage gate driving units, and each gate driving unit includes: an actuating unit configured to transmit an actuation signal; an energy storage unit configured to execute a charging process under the action of the actuation signal to output a driving voltage; a pull-up unit, a first pull-down unit, a second pull-down unit and a third pull-down unit operating under the action of the driving voltage, wherein a third pull-down unit pulls the driving voltage down to a second reference voltage to apply a reverse bias voltage to the gate-source and/or the gate-drain of transistors in the gate driving circuit, such that the threshold voltage of respective transistors under positive offset can offset reversely, thus effectively eliminating adverse effects of a threshold voltage offset phenomenon of the transistors on the gate driving circuit and improving the operation reliability of the gate driving circuit as well as the array substrate and the display panel thereof.
