Abstract

The embodiments of the present disclosure disclose a pixel driving circuit, a pixel driving method and a display apparatus. A pixel driving circuit for driving a light emitting element, comprising: a first control sub-circuit providing a data signal terminal signal to a first node based on a first signal control terminal signal; a second control sub-circuit providing a first power source terminal signal to a fourth node based on a third signal control terminal signal, and a signal of the fourth node to a second node based on a second signal control terminal signal; a third control sub-circuit providing a second power source terminal signal to a third node based on a fourth signal control terminal signal; an energy storage sub-circuit storing a potential difference between the first node and the second node; and a driving sub-circuit transmitting a driving current for driving the light-emitting element.
