Abstract
The present disclosure discloses a pixel circuit compensation method and device, and a display device. The method includes: when the display panel is in a preset display state, sensing a preset mobility compensation value corresponding to a driving transistor in the pixel circuit; according to the preset mobility compensation value, adjusting an initial mobility compensation value corresponding to the driving transistor to a target mobility compensation value, wherein a difference between the target mobility compensation value and the preset mobility compensation value is less than a threshold; based on the target mobility compensation value, when the display panel is in a non-display state, compensating a mobility of the driving transistor in a preset compensation manner.
