Abstract
A display substrate includes a plurality of circuit units. Each circuit unit includes a pixel driving circuit. The pixel driving circuit at least includes a first transistor, a second transistor, a third transistor, a fourth transistor, a ninth transistor, a first storage capacitor and a second storage capacitor. A second electrode of the first transistor is connected to a first electrode of the second transistor, the gate electrode of the third transistor, and a first end of the first storage capacitor, respectively. A second electrode of the fourth transistor is connected to a second electrode of the ninth transistor, a second end of the first storage capacitor, and a second end of the second storage capacitor, respectively.
