摘要： Provided are a pixel circuit and a driving method therefor, a display substrate, and a display apparatus, which belong to the technical field of display. In the pixel circuit, a light-emission adjusting circuit can adjust a data signal written by a data write circuit into a first node and can adjust the potential of a second node according to the potential of the first node; and a light-emission control circuit can output a reference signal to a third node under the control of the potential of the second node. Furthermore, a light emission driving circuit needs to output a drive signal to a light-emitting element in response to the potential of the third node, so as to drive the light-emitting element to emit light. Therefore, when the pixel circuit is driven, the potentials of all signals can be flexibly set to control a moment at which the reference signal is output to the third node, so as to control the duration of the light emission driving circuit outputting the drive signal, thereby realizing control over the light emission duration of the light-emitting element. Therefore, the light-emitting element can work under a high current density with relatively good uniformity, thereby ensuring a relatively good display effect.

摘要： 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.
