Abstract
A pixel driving circuit and a method for driving the same, a display panel, and a display apparatus are disclosed. The pixel driving circuit includes: a driving transistor, an organic light emitting diode, a light emitting control sub-circuit, a first scanning sub-circuit, a second scanning sub-circuit, a first storage sub-circuit, and a second storage sub-circuit. The light emitting control sub-circuit is configured to transmit a first voltage at a first voltage terminal to a second node under control of a light emitting control terminal. The first scanning sub-circuit is configured to cause a voltage at a first node to be equal to a voltage at the second node under control of a scanning signal terminal. The second scanning sub-circuit is configured to transmit a reference voltage at a reference voltage terminal to a third node under control of the scanning signal terminal. The first storage sub-circuit is configured to be charged or discharged under control of the second node and a data signal terminal. The second storage sub-circuit is configured to be charged or discharged under control of the first node and the third node.
