A pixel circuit, a driving method thereof and an organic electroluminescent display panel are disclosed. The pixel circuit comprises a driving transistor, a data write module, a compensation control module, a storage module and a light emitting control module. By means of cooperation of the above four modules, the working current of the driving transistor that drives the light emitting device to emit light can be unrelated to the threshold voltage of the driving transistor, which can avoid drift of the threshold voltage from influencing the light emitting device, thereby enabling the working current that drives the light emitting device to emit light to remain stable, so as to improve brightness uniformity of the displayed image.
