Abstract:
The present disclosure provides a driving method of a gate driving circuit. The driving method includes: outputting, by a plurality of shift register units of a shift register, signals sequentially, the plurality of shift register units being cascaded; determining, by a detection module, whether the plurality of shift register units has an abnormality according to one or more signals outputted from at least a part of the plurality of shift register units, and issuing a scan control command when it is determined that the plurality of shift register units has the abnormality; and controlling, by a scan control module, the shift register to perform forward scanning and reverse scanning under the scan control command.
