Claim 0:
1. A drive circuit of a display panel, comprising a voltage output module, wherein the drive circuit is configured to provide a voltage signal to the display panel via the voltage output module, and the voltage output module comprises:
a voltage input terminal configured to receive the voltage signal;
a voltage output terminal electrically coupled with the display panel;
a detection module electrically coupled with the voltage input terminal and configured to determine whether a voltage value of the voltage signal received at the voltage input terminal is greater than or equal to a preset voltage threshold, wherein the detection module is configured to output a first control signal when the voltage value of the voltage signal is greater than or equal to the preset voltage threshold and output a second control signal when the voltage value of the voltage signal is less than the preset voltage threshold; and
an isolation module electrically coupled between the voltage input terminal and the voltage output terminal and electrically coupled with the detection module, wherein the isolation module is configured to receive the first control signal and conduct an electrical coupling between the voltage input terminal and the voltage output terminal in response to the first control signal, and the isolation module is further configured to receive the second control signal and break the electrical coupling between the voltage input terminal and the voltage output terminal in response to the second control signal.
