Abstract
A pixel circuit, a driving method and a display device are provided. The pixel circuit includes a threshold compensation unit, configured to pull voltage of first node and voltage of first level terminal uniform, pull voltage of third node and voltage of second node uniform, and make the voltage of the first node and the voltage of the third node have an equipotential change; a driving unit, configured to output driving current; a data writing unit, configured to pull the voltage of the third node and the voltage of a data signal terminal uniform; a resetting unit, configured to pull a voltage of fourth node and a voltage of a third level terminal uniform; an EL light-emitting unit, configured to display gray scales through driving current; and a feedback unit, configured to make the voltage of the third node and the voltage of the fourth node have an equipotential change.
