Abstract
The present disclosure provides a pixel driving circuit, a pixel driving method, and a display panel. The pixel driving circuit includes a light emitting element electrically connected between a first node and a second node; a driving transistor connected in series between the second node and the light emitting element; and an auxiliary transistor connected in series between a third node and the light emitting element, where the auxiliary transistor is configured to generate an auxiliary current to jointly drive the light emitting element with a driving current generated by the driving transistor.
