DISPLAY SUBSTRATE AND DISPLAY APPARATUS

Disclosed is a display substrate. The display substrate comprises an array layer. The array layer comprises a plurality of pixels and a plurality of pixel driving circuits corresponding to the plurality of pixels. Each pixel driving circuit comprises a driving sub-circuit and a storage sub-circuit. The storage sub-circuit comprises a first capacitor and a second capacitor, which are connected in series. A first electrode plate of the first capacitor is coupled to a first node, and a second electrode plate of the first capacitor is coupled to a second node. A third electrode plate of the second capacitor is coupled to the second node, and a fourth electrode plate of the second capacitor is coupled to a first voltage signal end. The driving sub-circuit is coupled to the first node, the second node, and a third node. The driving sub-circuit is configured to generate a driving current under the control of the storage sub-circuit. The third node is used for transmitting the driving current to a light-emitting devi
