  • Pixel circuit, pixel driving method, display substrate, and display device
    Patent number: 12700359
    Abstract: A pixel circuit, a pixel driving method, a display substrate, and a display device are provided. The pixel circuit includes a driving circuit, a first reset circuit, a first node control circuit, a first light-emitting control circuit and a light-emitting element. The first reset circuit writes a first initial voltage to a first electrode of the light-emitting element under control of a potential of the first node. The first node control circuit controls the potential of the first node according to a data voltage and a threshold voltage of the driving transistor included in the driving circuit. The first light-emitting control circuit controls connection between a second end of the driving circuit and the first electrode of the light-emitting element under control of a light-emitting control signal. The driving circuit is configured to generate a driving current.
