Disclosed are a drive circuit, a driving method therefor, and a display device. The drive circuit is configured to drive a device to be driven to work; the drive circuit and said device are connected in series between a first working voltage end (VL1) and a second working voltage end (VL2); the drive circuit is configured to control formation of a current path between the first working voltage end (VL1) and the second working voltage end (VL2); the drive circuit comprises a drive sub-circuit, a writing sub-circuit, a compensation sub-circuit, and a gray-scale control sub-circuit, wherein the compensation sub-circuit is separately connected to the first working voltage end (VL1), a first scan signal end (G_A), a first node (N1), and a third node (N3) and is configured to compensate for the first node (N1) under control of the first scan signal end (G_A) and the first working voltage end (VL1).
