Abstract
The present invention discloses a pixel circuit and a driving method thereof, a display panel, and a display device, so as to improve brightness uniformity. The pixel circuit in the present invention comprises a control sub-circuit, a compensation sub-circuit, a driving transistor and a light emitting device. The present invention enables the driving current that drives the light emitting device to emit light to be uncorrelated with the threshold voltage of the driving transistor, so as to improve display uniformity of the panel.
