Classification: CPC G | IPC G

Claim 11:
12. A driving method of the pixel circuit of claim 1, comprising: a display stage and a sensing stage; wherein,
at the display stage, under a control of the first scan signal, the first node control sub-circuit writes a data voltage signal into the first node, under a control of the second scan signal, the second node control sub-circuit writes the reference voltage signal into the second node, and the driving sub-circuit is controlled, by potentials of the first node and the second node, to drive the light emitting device to emit light;
at the sensing stage, under the control of the first scan signal, the first node control sub-circuit writes a sensing signal into the first node, and under the control of the sensing control signal input by the sensing control line, the reading sub-circuit reads the potential of the second node and output it through a reading line.
