Claim 17:
18. A method for driving a display panel, the display panel including a plurality of sub-pixels; each sub-pixel including a respective pixel driving circuit; the pixel driving circuit including a driving sub-circuit, a signal writing sub-circuit, a compensation sub-circuit, a light-emitting control sub-circuit and an initialization sub-circuit; the signal writing sub-circuit being coupled to a data signal terminal, a first control signal terminal and the driving sub-circuit; the light-emitting control sub-circuit being coupled to a light-emitting control terminal and the driving sub-circuit, and the light-emitting control sub-circuit being configured to be further coupled to a light-emitting device; the initialization sub-circuit being coupled to the data signal terminal, a second control signal terminal and the compensation sub-circuit; the compensation sub-circuit being further coupled to the driving sub-circuit and the first control signal terminal;
the method for driving the display panel having a plurality of control cycles; each control cycle including a first stage, a second stage and a third stage;
the display panel further including switch controller groups, a source driver, a plurality of scanning signal lines, a plurality of first data signal lines and a plurality of second data signal lines; each switch controller group including a first switch and a second switch; the compensation sub-circuit being further coupled to a third control signal terminal;
the method for driving the display panel in a control cycle of the control cycles comprising:
in a first stage, inputting turn-on signals to the first control signal terminal and the second control signal terminal;
in a first sub-stage of the first stage, controlling, by the source driver, the first switch to be turned off and the second switch to be turned on, and providing, by the source driver, an initial voltage to a second end of the first switch and a second end of the second switch; and
in a second sub-stage of the first stage, controlling, by the source driver, the first switch to be turned on and the second switch to be turned off, and providing, by the source driver, the data voltage to the second end of the first switch and the second end of the second switch;
in a second stage, inputting turn-on signals to the first control signal terminal and the third control signal terminal;
in a first sub-stage of the second stage, controlling, by the source driver, the first switch to be turned off and the second switch to be turned on, and providing, by the source driver, the data voltage to the second end of the first switch and the second end of the second switch; and
in a second sub-stage of the second stage, controlling, by the source driver, the first switch to be turned on and the second switch to be turned off, and providing, by the source driver, the initial voltage to the second end of the first switch and the second end of the second switch; and
in a third stage, inputting the turn-on signal to the third control signal terminal;
in a first sub-stage of the third stage, controlling, by the source driver, the first switch to be turned off and the second switch to be turned on, and providing, by the source driver, the initial voltage to the second end of the first switch and the second end of the second switch; and
in a second sub-stage of the third stage, controlling, by the source driver, the first switch to be turned on and the second switch to be turned off, and providing, by the source driver, the data voltage to the second end of the first switch and the second end of the second switch.
