A pixel driving circuit and a driving method therefor, a pixel unit, and a display apparatus. The pixel driving circuit comprises a first transistor (T1), a second transistor (T2), a third transistor (T3), a fourth transistor (T4), a fifth transistor (T5), a sixth transistor (T6), a storage capacitor (Cst). The circuit is switched on or off and charged or discharged by means of the first transistor to the sixth transistor (T1-T6) and the storage capacitor (Cst), and accordingly, a light-emitting device (D) can be prevented from being affected by a threshold voltage, and the influence to the driving current flowing through the light-emitting device (D) can also be reduced when nonlinear changes occur in an ohmic voltage drop of a first voltage end (Vdd) and a gate-source voltage of the fifth transistor (T5). |
