Abstract
A pixel driving circuit, a driving method and an organic light-emitting display panel are provided. The pixel driving circuit includes: a first transistor, a second transistor, a third transistor, a fourth transistor and a fifth transistor, a sixth transistor, a seventh transistor and an eighth transistors, and a capacitor. A first node is present between the fourth transistor and the fifth transistor. The seventh transistor is coupled between a reference voltage line and the first node, and the eighth transistor is coupled between the reference voltage line and an anode of the light-emitting element.
