  • Publication number: 20250087152
    Abstract: A display substrate includes an array substrate including pixels and pixel driving circuits. A pixel driving circuit includes a driving sub-circuit and a storage sub-circuit. The storage sub-circuit includes: a first capacitor coupled to a first node and a second node, and a second capacitor coupled to the second node and a first voltage signal terminal. The driving sub-circuit is configured to generate a driving current under control of the storage sub-circuit and transmit the driving current to a light-emitting device. In a direction perpendicular to the array layer, the first plate, the second plate, the third plate and the fourth plate have an overlapping region therebetween.
