Abstract
The present disclosure provides a pixel circuit and a method for driving the same, and a display panel. The pixel circuit includes a driving sub-circuit and a light-emitting control sub-circuit. The driving sub-circuit is configured to transmit a first power voltage at a first power signal terminal to a second node. The light-emitting control sub-circuit is configured to: transmit a voltage at the second node and a second power voltage at the second power signal terminal to the first electrode of the first light-emitting element and the second electrode of the first light-emitting element respectively in a first period, to the first electrode of the second light-emitting element and the second electrode of the second light-emitting element respectively in a second period, and to the first electrode of the third light-emitting element and the second electrode of the third light-emitting element respectively in a third period.
