Claim 19:
20. A driving method of a pixel circuit configured to drive the pixel circuit of claim 1, the method comprising:
the first control sub-circuit provides the signal of the first initial signal terminal or the third node to the first node under control of the first reset signal terminal and the second scanning signal terminal, and provides the signal of the second initial signal terminal to the fourth node under control of the second reset signal terminal;
the second control sub-circuit provides the signal of the third initial signal terminal or the data signal terminal to the second node under control of the third reset signal terminal and the first scanning signal terminal;
the third control sub-circuit provides a first signal to the third node in the display stage and a second signal to the third node or obtains a signal of the third node in the non-display stage under control of the third reset signal terminal;
the driving sub-circuit provides driving current to the third node under control of the first node and the second node;
the light emitting control sub-circuit provides the signal of the first power supply terminal to the second node and the signal of the third node to the fourth node under control of the light emitting signal terminal.
