    Abstract: Provided are a pixel circuit and a drive method thereof, a display substrate, and a display device. The pixel circuit includes a current source sub-circuit and a voltage divider sub-circuit. The current source sub-circuit is configured to update a stored drive voltage based on a voltage at the data signal terminal when the gate signal terminal receives a gate drive signal, and output a drive current based on the stored drive voltage when the switch signal terminal receives a light-emitting control signal, a current value of the drive current being positively correlated to a voltage value of the drive voltage. The voltage divider sub-circuit is configured to regulate an equivalent resistance value of the voltage divider sub-circuit in an output path of the drive current based on a signal received by the voltage division control signal terminal.
