Abstract
The present application discloses a noise reduction voltage regulation circuit, a display panel and a noise reduction method. The noise reduction voltage regulation circuit includes a time domain selection module and a noise regulation module. The time domain selection module is connected to the Q point of the gate drive unit of the n+1th level and the n‑1th level, and the input end of the noise regulation module is connected to the Q point of the nth level gate drive unit; the time domain selection module generates a time domain selection voltage according to the voltage of the Q point of the upper and lower level gate drive units of the nth level gate drive unit and a first reference voltage, and the noise regulation module generates a noise reduction voltage according to the time domain selection voltage and the voltage of the Q point of the nth level gate drive unit, and outputs it to the input end of all gate drive units of the gate drive circuit. The present application realizes real-time regulation of the noise reduction voltage through the voltage of the Q point of the upper and lower level gate drive units of the nth level gate drive unit of the time domain selection module, so as to avoid lowering the noise reduction voltage when noise is not detected, resulting in power waste.
