A pixel driving circuit, a pixel driving method and a display apparatus. The pixel driving circuit comprises a pixel sub-circuit and a power source control sub-circuit. The pixel sub-circuit comprises a first connection terminal (P1), a second connection terminal (P2) and a light-emitting element, and is configured to receive a first voltage and a second voltage from the first connection terminal (P1) and the second connection terminal (P2), respectively, so as to drive the light emission of the light-emitting element. The power source control sub-circuit is respectively connected to the first connection terminal (P1), the second connection terminal (P2), a first power source terminal (VDD) and a second power source terminal (VSS). The power source control sub-circuit is configured to: in a first state, control the first power source terminal (VDD) and the second power source terminal (VSS) to respectively provide the first voltage and the second voltage to the first connection terminal (P1) and second connection terminal (P2) of the pixel sub-circuit and to store energy; and in a second state, release the energy to the first connection terminal (P1) and second connection terminal (P2) of the pixel sub-circuit to drive the light emission of the light-emitting element. By means of arranging a power source control sub-circuit, current through time of wiring between a high-voltage power source and a low-voltage power source can be reduced, the electrical energy loss of the wiring is reduced, and electrical energy is saved.
