Each GOA unit comprises: a pull up control module, an output module, a pull down module and a pull down maintenance module; for N-th GOA unit: the 41st TFT of pull down module having a gate receiving a scan signal from (N+4)-th GOA unit, a source connected to a circuit start signal, and a drain connected to the first node, and the circuit start signal having a low voltage level lower than or equal to 0V and higher than the low voltage signal; so that when the scan signal from (N+4)-th GOA unit changing from high voltage to low voltage, the gate-source voltage difference of the 41st TFT being negative to effectively reduce the current leakage and prevent the current leakage from affecting the first node voltage, improve circuit stability, facilitate cost reduction and narrow border."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"GOA circuit having negative gate-source voltage difference of TFT of pull down module","description":"The invention provides a GOA circuit, comprising a plurality of cascaded GOA units.
