20 Claims

1. A gate driver circuit, applicable to a display panel, wherein the display panel comprises a plurality of rows of pixels: the gate driver circuit comprising at least one gate driver sub-circuit: wherein the gate driver sub-circuit comprises:

at least two shift register groups, wherein each shift register group comprises a plurality of shift register units, first output terminals and first input terminals of the plurality of shift register units in each shift register group are sequentially cascaded, and first output terminals and first reset terminals of the plurality of shift register units in the at least two shift register groups are sequentially cascaded:

at least two first dummy units, wherein the at least two first dummy units are respectively coupled to a same input enable terminal and the at least two shift register groups, and the at least two first dummy units are configured to transmit input signals to the at least two shift register groups based on an input enable signal provided by the input enable terminal, such that each shift register unit transmits the input signal to the first input terminal of another cascaded shift register unit and transmits a reset signal to the first reset terminal of another cascaded shift register unit via the first output terminal; and

at least two second dummy units, wherein the at least two second dummy units are coupled to the at least two shift register groups and configured to transmit reset signals to the at least two shift register groups based on input signals transmitted by the first output terminals of the plurality of shift register units in the at least two shift register groups:

wherein the first output terminal of each shift register unit is further coupled to at least one row of pixels, and each shift register unit is configured to drive, based on the received signal, the at least one row of pixels to emit light.
