POWER SUPPLY CIRCUIT, DRIVING APPARATUS AND DISPLAY APPARATUS

This application discloses a power supply circuit, a driving apparatus, and a display apparatus, and relates to the field of display technologies. The power supply circuit includes: a first power supply module and a second power supply module. An output end of the first power supply module is connected to a first output end of the second power supply module, and is configured to be connected to a first input end of the driving module. An output end of the first power supply module is configured to output a first voltage signal, and a first output end of the second power supply module is configured to output a second voltage signal. A second output end of the second power supply module is configured to be connected to a second input end of the driving module, so as to output a third voltage signal. Voltage signals that are output by 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 are used to instruct the driving module to generate a gate turn-on signal. The power supply circuit in this application can increase a voltage of the gate turn-on signal generated by the driving module, so that the voltage of the gate turn-on signal can meet a high refresh frequency requirement of a display panel.
