Abstract: A pixel circuit, a driving method thereof and related device are disclosed. The pixel circuit comprises a drive transistor, a reset module, a compensation module, a data write module, a light emitting control module and a light emitting device. The reset module is configured to provide a reference signal to a gate electrode of the drive transistor. The compensation module is configured to store a threshold voltage of the drive transistor. The data write module is configured to write a data signal onto the gate electrode of the drive transistor. The light emitting control module is configured to control the drive transistor to drive the light emitting device to emit light. With the pixel circuit above, a drive current for the light emitting device to emit light is only relevant to a voltage of the data signal and a voltage of the reference signal, and irrelevant to the threshold voltage of the drive transistor and a voltage of a first power supply, so that the threshold voltage of the drive transistor and IR drop of the first power supply will not affect the current flowing through the light emitting device, and thus image brightness uniformity of a display area of a display device can be improved.
