Abstract
A compensation method a pixel circuit and a display panel are provided. In the compensation method, a gate potential and a source potential of a driving transistor in a writing stage are obtained and a compensation coefficient of the pixel circuit is determined, and then a light-emitting current flowing through the driving transistor in a light-emitting stage is determined based on the compensation coefficient, the gate potential and the source potential of the driving transistor in the writing stage. The compensation coefficient can adjust transmission loss of the gate potential and the source potential of the driving transistor in the writing stage, so as to ensure that the light-emitting current flowing through the driving transistor in the light-emitting stage is desired, without causing the phenomenon of shift in brightness.
