The gate-driving unit circuit includes an input sub-circuit coupled to an input terminal and a pull-up node, and configured to charge a pull-up node to a turn-on voltage level. Additionally, the gate-driving unit circuit includes a pre-pull-down sub-circuit coupled to a pull-down node, a pre-pull-down node, and a reference voltage terminal, and configured to pull down voltage levels at the pull-down node and the pre-pull-down node to a turn-off voltage level before the pull-up node is charged to the turn-on voltage level. Therefore, potential charging delay in the pull-down node caused by a transistor threshold voltage shift is avoided. The gate-driving unit circuit further includes a pull-down sub-circuit, a pull-down control sub-circuit, a noise-reduction sub-circuit, a reset sub-circuit, and an output sub-circuit to couple with the input sub-circuit and the pre-pull-down sub-circuit to output a gate-driving signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gate-driving unit circuit having pre-pull down sub-circuit, gate driver on array circuit, driving method, and display apparatus thereof","description":"The present application discloses a gate-driving unit circuit.
