Supplement resetting module, gate driver circuit and display device

A gate driver circuit, comprising multiple levels of shift register units and 2N clock signal lines, wherein

• the shift register unit at each level comprises an output resetting end and a pull-up node resetting end;
• the multiple levels of shift register units comprise display shift register units and resetting shift register units, and at least the shift register units at the latter N levels are the resetting shift register units, where N is a natural number greater than 0;
• among at least the multiple levels of shift register units including the display shift register units and a first-level resetting shift register unit of the resetting shift register units at the latter N levels, an output resetting end of a current-level shift register unit is directly connected to a pull-up node resetting end of a previous-level shift register unit;
• the gate driver circuit further comprises a first supplement resetting module, and at least the first-level resetting shift register unit of the resetting shift register units at the latter N levels corresponds to the first supplement resetting module;
• the first supplement resetting module comprises a first pull-up control unit, a first pull-down control unit, a first clock signal input end, a predetermined level input end, a first control signal input end, a second control signal input end and a first signal output end;
• a control end of the first pull-up control unit is connected to the first clock signal input end, an output end of the first pull-up control unit is connected to the first signal output end, and in the case of an effective signal is applied to the first clock signal input end, the first pull-up control unit is configured to enable the first clock signal input end to be electrically connected to the first signal output end;
• a first control end of the first pull-down control unit is directly connected to the first control signal input end, a second control end of the first pull-down control unit is directly connected to the second control signal input end, an input end of the first pull-down control unit is connected to the predetermined level input end, an output end of the first pull-down control unit is connected to the first signal output end, and in the case that an effective signal is applied to any of the first control signal input end and the second control signal input end, the first pull-down control unit is configured to enable the predetermined level input end to be electrically connected to the first signal output end;
• the first control signal input end of the first supplement resetting module is connected to an input end of the resetting shift register unit corresponding to the first supplement resetting module, the second control signal input end of the first supplement resetting module is connected to an output end of the resetting shift register unit corresponding to the first supplement resetting module, and the first signal output end of the first supplement resetting module is connected to an output resetting end of the resetting shift register unit corresponding to the first supplement resetting module;
• and
• in the case that an effective signal is outputted from the resetting shift register unit corresponding to the first supplement resetting module, a clock signal from the first clock signal input end of the first supplement resetting module is an ineffective signal.
