Abstract
The present invention provides a voltage output device, which comprises a direct-current power supply, a reference level input terminal, a predetermined level output terminal, a voltage regulation module and a control signal generation module, the control signal generation module comprises a control signal generation unit, the voltage regulation module comprises a plurality of storage capacitors, wherein the control signal generation unit can send a charging control signal to the voltage regulation module in a charging stage of the voltage output device, and send an operation control signal to the voltage regulation module in an operating stage of the voltage output device. The present invention further provides a gate driving circuit and a display apparatus. With the voltage output device provided by the present invention, a high-level voltage that is high enough and/or a low-level voltage that is low enough can be outputted, thereby satisfying specific application requirements.
