Abstract
A threshold voltage detecting method is disclosed in the present application. In the threshold voltage detecting method provided in the present application, a path between a driving transistor and a detecting circuit is shut down during detecting, so that a current flowing through the driving transistor in a detecting stage only needs to charge a storage capacitor, but does not need to charge a parasitic capacitor on the detecting circuit, thereby shortening a threshold voltage detecting time of the driving transistor, and further improving threshold voltage detecting efficiency of the driving transistor.
