1. A driving circuit, comprising a pixel circuit and a demultiplexing circuit, wherein:
the pixel circuit includes at least a driving transistor, a light-emitting device, and a data writing module;
the driving transistor is connected between a first power signal terminal and the light-emitting device in series, to generate a driving current;
the data writing module is connected between the driving transistor and the demultiplexing circuit in series, to provide a data signal to the driving transistor;
an output terminal of the demultiplexing circuit is connected to an input terminal of the data writing module through a data line; and
the demultiplexing circuit is configured to write the data signal to the data line at the same time when the driving transistor is performing a threshold compensation.
