Inventors include Huang, Yao Number; Zhu, Li; and Liu, Jia.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: Disclosed are a pixel driving circuit and a driving method therefor, a display substrate, and a display device. The pixel driving circuit (1) comprises: a driving transistor (T3), a first reset subcircuit (51), a second reset subcircuit (52), a light-emitting control subcircuit (30), a data writing circuit (10), a first energy storage element (41), and a second energy storage element (42); the first reset subcircuit (51) is configured to write an initialization voltage signal to a third node (N3) in response to a first reset signal; the second reset subcircuit (52) is configured to, in response to a second reset signal, connect a gate of the driving transistor (T3) to a fourth node (N4) and reset the gate of the driving transistor (T3) and the fourth node (N4); the data writing subcircuit (10) is configured to write a data voltage signal to the second energy storage element (42) in response to a scanning signal; and the light-emitting control subcircuit (30) is configured to connect a first electrode of the driving transistor (T3) to a power supply end in response to a first light-emitting control signal, and transmit the data voltage signal to the gate of the driving transistor (T3) in response to a second light-emitting control signal.
