Abstract:
The embodiments of the present invention provide a driving circuit and a driving method, a GOA unit, a GOA circuit and a display device, to improve the response speed of the circuit and reduce the leakage current. This driving circuit comprises: at least one pull-up/pull-down unit each configured to pull up or pull down a voltage of a controlled node; each pull-up/pull-down unit comprises at least one double-gate transistor, the double-gate transistor is used to accelerate the charge or discharge of the node when being turned on, or is used to reduce the leakage current passing the node when being turned off. The embodiments of the present invention are suitable to be applied to the display production.
