Embodiments of the present disclosure provide a pixel circuit and a drive method thereof, an array substrate, and a display panel. The pixel circuit includes a drive transistor, a data write circuit, a light emission control circuit, a compensation circuit, a reset circuit, and a light emitting device. A first control electrode of the drive transistor is coupled to a first node, a second control electrode of the drive transistor is coupled to a second node, a first electrode of the drive transistor is coupled to a first voltage signal terminal, and a second electrode of the drive transistor is coupled to a third node and may provide a drive current. The light emitting device is coupled between the light emission control circuit and a second voltage signal terminal and may emit light based on the drive current.
