Abstract: The present disclosure provides a pixel circuit, a method for driving the same, a display substrate, and a display device, which belong to the field of display technologies. The pixel circuit includes a compensating circuit which can adjust an electric potential of a second control node (a gate of a transistor controlling conduction or non-conduction between a first connection node and a second connection node) based on an electric potential of a first control node, and adjust an electric potential of the second control node based on an electric potential of the second connection node. When the pixel circuit is driven, electric potential of each control signal can be controlled, such that influence of a threshold voltage of a transistor on an electric potential finally output to the second control node is relatively small, that is, influence of drifting of a threshold voltage on display uniformity is reduced. The display device according to the present disclosure achieves a good display effect.
