Abstract
A drive circuit, a driving method therefor, and a display device. The drive circuit comprises: an initialization circuit () configured to provide a signal of an initialization signal terminal (VINIT) to a gate of a driving transistor (M) in response to a control signal; a first control circuit () configured to input the control signal to the initialization circuit () according to a signal of a first control terminal (VC) and a signal of a second control terminal (VC); a data writing circuit () configured to provide a signal of a data signal terminal (DA) to the driving transistor (M) in response to a signal of a first scanning signal terminal (GA); the driving transistor (M) configured to generate a driving current according to the signal of the data signal terminal (DA); and a light-emitting device (L) configured to emit light under the control of the driving current.
