1. A display panel, comprising:
a first display area and a second display area;
pixel circuits comprising first pixel circuits and second pixel circuits, at least one of the first pixel circuits being connected to at least one of light-emitting elements in the first display area, and at least one of the second pixel circuits being connected to at least one of light-emitting elements in the second display area; and
first pixel units and second pixel units, at least one of the first pixel units comprising a first pixel circuit and at least one light-emitting element connected to the first pixel circuit, and at least one of the second pixel units comprising a second pixel circuit and at least one light-emitting element connected to the second pixel circuit;
wherein at least one of the first pixel units comprises the light-emitting element emitting light of a first color, at least one of the second pixel units comprises the light-emitting element emitting light of a first color, and the first color is different from the second color,
wherein at least one of the first pixel units is configured to receive a first power supply signal V1 and a second power supply signal V2, V1>V2; and
at least one of the second pixel units is configured to receive a third power supply signal V3 and a fourth power supply signal V4, V3>V4;
wherein |V1−V2|≠|V3−V4|;
in the first display area, a first power supply signal and a second power supply signal received by a light-emitting element emitting light of a first color are V11 and V12, respectively;
and a first power supply signal and a second power supply signal received by a light-emitting element emitting light of a second color are V21 and V22, respectively; and
in the second display area, a third power supply signal and a fourth power supply signal received by a light-emitting element emitting light of a first color are V13 and V14, respectively;
and a third power supply signal and a fourth power supply signal received by a light-emitting element emitting light of a second color are V23 and V24, respectively;
wherein |V13−V11|+|V14−V12|/|V23−V21|+|V24−V22|.
