A pixel unit circuit, a compensating method thereof and a display device. The pixel unit circuit comprises a driving transistor (T1), a first transistor (T2), a second transistor (T3), a third transistor (T4), a fourth transistor (T5), a storage capacitor (C ST ) and a light-emitting device (OLED). The pixel unit circuit, the compensating method thereof and the display device may compensate the light emitting device by combining an internal compensation and an external compensation, and have advantages of both the internal compensation and the external compensation. The Mura phenomenon caused by non-uniformity in threshold voltages or drifts of threshold voltages in the N-type depletion or enhanced driving transistor TFT may be eliminated effectively by the internal compensation, which may enhance a display effect. Additionally, the pixel unit circuit, the compensating method thereof and the display device may have a function for extracting characteristics of the driving TFT and characteristics of the light emitting device, which may be applicable to the external compensation driving effectively. |
