A pixel driving circuit for driving a light-emitting device of a display apparatus is provided. The display apparatus includes a first input terminal and a second input terminal. The pixel driving circuit includes a first switching circuit, a second switching circuit, and a storing circuit. The first switching circuit is connected to the first input terminal and the second input terminal. The second switching circuit is connected to the light-emitting device. The storing circuit is connected to the first switching circuit and the second switching circuit respectively. The first switching circuit, in response to signal states of the first input terminal and the second input terminal, enables the storing circuit to store a voltage that produces a constant current. The second switching circuit controls the constant current flowing through the light-emitting device.
