US Patent 11341898 Pixel driving circuit, pixel driving method and display device

A pixel driving circuit, a pixel driving method and a display device are provided. The pixel driving circuit includes a pixel sub-circuit and a power supply control sub-circuit, the pixel sub-circuit includes a first connection terminal, a second connection terminal and a light-emitting element, and is configured to respectively receive a first voltage and a second voltage to drive the light-emitting element to emit light. The power supply control sub-circuit is configured to, in a first state, control the first power supply terminal to provide the first voltage to the first connection terminal of the pixel sub-circuit, control the second power supply terminal to provide the second voltage to the second connection terminal of the pixel sub-circuit, and store energy; and in a second state, release the energy to the first connection terminal and the second connection terminal of the pixel sub-circuit to drive the light-emitting element to emit light.
