Abstract

The present disclosure provides a system and a method for controlling a charge pump circuit, and a display device. The system includes the charge pump circuit configured to output a driving voltage to a gate driver circuit; and a controlling device in communication with the charge pump circuit and a timer and configured to, when a working time of the gate driver circuit is equal to a predefined working time threshold, reset the working time of the gate driver circuit to an initial value, acquire a compensating voltage corresponding to the working time of the gate driver circuit in accordance with a correspondence between the working time and the compensating voltage, output a compensating voltage signal and increase the driving voltage outputted by the charge pump circuit by the compensating voltage.
