Abstract:
The invention provides a GOA circuit, comprising a plurality of cascaded GOA units. 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 41 st  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 41 st  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.

Claim (Index 1):
A gate driver on array (GOA) circuit, which comprises: a plurality of cascaded GOA units, with each GOA unit comprising: a pull up control module, an output module, a pull down module and a pull down maintenance module;\n for an positive integer N, except the first to the fourth GOA units and the last fourth to the last GOA units, in the N-th GOA unit: the pull up control module receiving a cascade-propagate signal from (N\u22124)-th GOA unit and a high voltage signal, connected to a first node, for pulling up voltage at the first node to the high voltage signal based on the cascade-propagate signal from (N\u22124)-th GOA unit; the output module receiving clock signal and connected to the first node, for outputting a scan signal and a cascade-propagate signal under control by the voltage of the first node; the pull down module comprising a 41 st  TFT, the 41 st  TFT having a gate connected to receive 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; the pull down maintenance module receiving the scan signal and a low voltage signal, connected to the first node, for maintaining the scan signal and the voltage of the first node at the low voltage signal after the pull down module pulling down the voltage of the first node; the circuit start signal being a pulse signal, and the circuit start signal having a low voltage level lower than or equal to 0V and higher than the low voltage signal.
