A driving circuit includes a first signal-input terminal, a second signal-input terminal, a third signal-input terminal, a fourth signal-input terminal, a signal-output terminal, and a voltage-boosting unit including a first module, a second module, a third module, and a first capacitor. The first module transmits the signal at the third signal-input terminal to a first terminal of the first capacitor during a first time period, and blocks signal transmission during a second time period. During the first time period and the second time period, the second module transmits the signal at the third signal-input terminal to the third module to allow the signal at the fourth signal-input terminal to be transmitted to a second terminal of the first capacitor. During a third time period, the second module and the third module both block signal transmission. The first terminal of the first capacitor is connected to the signal-output terminal for output.
