摘要： The present disclosure provides a pixel circuit. The pixel circuit may compensate the threshold voltage of the driving unit, such that the driving current provided by the driving unit to the light emitting device is only relevant to the difference between the voltage acting on the signal input terminal acting of the driving unit and the voltage of the data signal, which thereby eliminates the influence caused by the variation of the threshold voltage of the driving unit and improves the uniformity of an displayed image. In addition, the present disclosure also relates to a driving method of the pixel circuit, as well as a display substrate and a display apparatus both including the pixel circuit.
