Abstract
The present invention discloses a control circuit for a gate driver circuit, an operating method thereof and a display device comprising the control circuit, the control circuit includes: a detection circuit, a power supply and a charge pump circuit, wherein, the detection circuit is used to generate a digital control signal corresponding to an ambient temperature based on the ambient temperature of the gate driver circuit, the power supply is used to supply an initial voltage to a pump charge circuit and the pump charge circuit is used to adjust the initial voltage based on the digital control signal to generate a driving voltage, and output the driving voltage to the gate driver circuit. By enabling the driving voltage to be dynamically adjustable, the power consumption of the gate driver circuit is reduced, and the life of the thin film transistor in the gate driver circuit is lengthened.
