More Information
Summary:The embodiments of the present disclosure provide a gate driving circuit, an array substrate, a display panel and a driving method. The gate driving circuit comprises: at least a Gate driver on Array (GOA) unit GOAn and a GOA unit GOAn+m, an output terminal of GOAn being connected to an input terminal of GOAn+m, an output terminal of GOAn+m is connected to a reset terminal of GOAn; and an electrical leakage compensation module having two input terminals connected to output terminals of GOAn and GOAn+m, respectively, a control terminal connected to a signal line, and an output terminal connected to a Pull-Up (PU) node of GOAn+m, and configured to compensate for a voltage at the PU node of GOAn+m in response to receipt of the electrical leakage compensation signal VLHB. According to the embodiments of the present disclosure, an electrical leakage compensation module is added between two cascaded GOA units for compensating for a voltage decrease due to electrical leakage by charging the GOA unit at the next stage.
