Abstract
A pixel circuit, a driving method and a display device are provided. The pixel circuit includes a light-emitting element, a driving circuit, a driving node control circuit and a first write-in circuit; the driving circuit is configured to generate a driving current for driving the light-emitting element under the control of a potential at a driving node; the first write-in circuit is configured to write a first data voltage into a control node under the control of a write-in control signal; and the driving node control circuit is configured to control the driving node to be electrically coupled to or electrically decoupled from a first voltage end under the control of a potential at the control node.
