1. A power supply circuit, comprising:
a first power supply module having an output end; and
a second power supply module having a first output end and a second output end, wherein the first output end is connected to the output end of the first power supply module,
wherein both the output end of the first power supply module and the first output end of the second power supply module are configured to be connected to a first input end of a driving module wherein the second output end of the second power supply module is configured to be connected to a second input end of the driving module,
wherein when the first power supply module works and the second power supply module sleeps, the output end of the first power supply module outputs a voltage signal to instruct the driving module to trigger the second power supply module to work,
wherein when both the first power supply module and the second power supply module work, the output end of the first power supply module, the first output end of the second power supply module, and the second output end of the second power supply module all output voltage signals to instruct the driving module to generate a gate turn-on signal configured to drive a switching transistor in a display panel to turn on, and
wherein a voltage of the voltage signal output by the output end of the first power supply module is less than a voltage of the voltage signal output by the first output end of the second power supply module.
