Abstract

A display substrate and a driving method therefor, and a display device. The display substrate comprises a plurality of circuit units, at least one circuit unit comprising a pixel driving circuit, which at least comprises a compensation transistor (T2), a driving transistor (T3), a data writing transistor (T4), a first storage capacitor (10), and a second storage capacitor (20), wherein a gate electrode of the data writing transistor (T4) is connected to a first scan signal line (21); a gate electrode of the compensation transistor (T2) is connected to a second scan signal line (22); a first end of the first storage capacitor (10) is connected to a gate electrode of the driving transistor (T3); a first end of the second storage capacitor (20) is connected to a first electrode of the driving transistor (T3); and a second end of the first storage capacitor (10) and a second end of the second storage capacitor (20) are connected to a first power line (53).
