Abstract
Provided are a pixel circuit and a drive method thereof, a display panel and a display device. The pixel circuit includes: a drive transistor, a storage capacitor, a data writing module, a threshold compensation module, and an organic light emitting element. The data writing module is electrically connected to a gate of the drive transistor and a first plate of the storage capacitor, and is configured to write a data signal to the gate of the drive transistor and the first plate of the storage capacitor at a data writing phase. The threshold compensation module is electrically connected to a second plate of the storage capacitor, and is configured to adjust a potential of the second plate of the storage capacitor to a first potential at the data writing phase, and adjust the potential of the second plate of the storage capacitor to a second potential.
