19. A driving method of an MLED display panel, wherein the driving method is configured to drive an MLED display panel comprising a plurality of pixel driving circuits, wherein at least one of the pixel driving circuits comprises a first transistor, a second transistor, a capacitor, and a first light emitting assembly, wherein,
a first end of the first transistor is electrically connected to a first end of the second transistor and one end of the capacitor, respectively, to form a first internal node;
a second end of the first transistor is electrically connected to a third end of the second transistor and the other end of the capacitor, respectively, to form a second internal node;
a second end of the second transistor is electrically connected to one end of the first light emitting module; and
a third end of the first transistor is electrically connected to a first power supply voltage, and the other end of the first light emitting module is electrically connected to a second power supply voltage, and
wherein at least one of the pixel driving circuits further comprises a second light emitting assembly, wherein one end of the second light emitting assembly is electrically connected to the first power supply voltage, and the other end of the second light emitting assembly is electrically connected to the third end of the first transistor,
the driving method comprises:
setting a first power supply voltage to a high level and a second power supply voltage to a low level in a first display period; and
setting the first power supply voltage to the low level and the second power supply voltage to the high level in a second display period.
