Pixel driving circuit,with two display modes driving method thereof, and display device
A pixel driving circuit includes a first power signal terminal, a second power signal terminal, a drive transistor, a light-emitting element, and a storage element. A gate of the drive transistor is connected to a first node, a first electrode of the drive transistor is connected to a second node, and a second electrode of the drive transistor is connected to a third node. A positive electrode of the light-emitting element is connected to a fourth node, and a negative electrode is connected to the second power signal terminal. A first terminal of the storage element is connected to a fixed potential, and a second terminal of the storage element is connected to the first node. In a same time frame of a display, a driving process using the pixel driving circuit includes a non-light-emitting phase and a light-emitting phase.
