Abstract: 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.
