16. The display device according to claim 15, wherein the organic light-emitting sub-pixel comprises a data writing transistor, a driving transistor, a compensation transistor, a storage capacitor and an organic light-emitting diode;
wherein a first terminal of the data writing transistor is connected to the digital-to-analog converter through a data line for receiving the data compensation analog voltage or the original data analog voltage output by the digital-to-analog converter;
a control terminal of the data writing transistor is connected to a gate driver through a first scan line for receiving a first scan signal provided by the first scan line;
a second terminal of the data writing transistor, a first terminal of the storage capacitor and a control terminal of the driving transistor are connected to a first node;
a second terminal of the storage capacitor and a first terminal of the driving transistor are connected to a first power signal terminal for receiving the first power signal provided by the first power signal terminal;
a second terminal of the driving transistor, a first pole of the organic light-emitting diode and a first terminal of the compensation transistor are connected to a second node;
a second pole of the organic light-emitting diode is connected to a second power supply signal terminal for receiving a second power supply signal provided by the second power supply signal terminal;
a control terminal of the compensation transistor is connected to the gate driver through a second scan line for receiving a second scan signal provided by the second scan line, and a second terminal of the compensation transistor is connected to the analog-to-digital converter through a compensation line; and
wherein the analog-to-digital converter is configured to acquire an actual driving analog voltage at the second node through the compensation line when the data writing transistor and the compensation transistor are respectively turned on in response to the first scan signal and the second scan signal, and perform analog-to-digital conversion on the actual driving analog voltage to convert the actual driving analog voltage into the actual driving digital voltage.
