1. A pixel circuit, comprising a drive module, a data write module, an auxiliary module, a compensation module, a storage module, a coupling module, and a light-emitting module, wherein
the data write module is configured to write a data-voltage-related voltage to a control terminal of the drive module through the auxiliary module;
the compensation module is connected between a first terminal of the drive module and the control terminal of the drive module and is configured to compensate for a threshold voltage of the drive module;
the coupling module is connected to the compensation module and is configured to adjust a voltage at the control terminal of the drive module according to a received jump voltage through the compensation module;
the storage module is connected to the control terminal of the drive module and is configured to store the voltage at the control terminal of the drive module; and
the drive module is configured to provide a drive signal to the light-emitting module according to the voltage at the control terminal to drive the light-emitting module to emit light.
