Abstract: The present invention provides a pixel circuit, a driving method thereof and a display device. The pixel circuit comprises a drive module, an energy storage module, an electroluminescent module, a data voltage writing module, a threshold compensation module and a reset module, and also comprises an operating voltage input terminal, a data voltage input terminal and a plurality of control signal input terminal. The threshold compensation module is capable of introducing the voltage on the compensation voltage input terminal so as to set the voltage on the control terminal of the drive module to be a sum of the threshold voltage of the drive module and the operating voltage, thus the driving current flowing through the electroluminescent units is not affected by the threshold voltage of corresponding drive modules, such that the problem of uneven display brightness caused by the threshold voltage drift of driving transistors can be solved.
