1. A pixel circuit comprising:
a drive module;
a data write module, wherein the data write module is configured to, in a data write and threshold compensation stage, write a voltage related to a data voltage to a control terminal of the drive module;
a first compensation module, wherein a second terminal of the first compensation module is connected to a first terminal of the drive module and the first compensation module is configured to, in the data write and threshold compensation stage, perform a threshold compensation on the drive module;
a second compensation module, wherein a first terminal of the second compensation module is connected to the control terminal of the drive module and a second terminal of the second compensation module is connected to a first terminal of the first compensation module;
a light-emitting module,
a storage module, wherein the storage module is configured to store the voltage of the control terminal of the drive module; and
a coupling module, wherein the coupling module is configured to, in a compensation adjustment stage, couple a jump voltage or a fixed voltage to at least one of the second terminal of the second compensation module or an internal node of the second compensation module and the drive module is configured to provide a drive signal to the light-emitting module according to the voltage of the control terminal to drive the light-emitting module to emit light.
