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 is connected to at least one of light-emitting elements in the first display area, and at least one of the second pixel circuits is 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 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−V3|+|V2−V4|≠0;
in the first display area, at least one of first pixel circuits is connected to m1 light-emitting elements, and in the second display area, at least one of second pixel circuits is connected to m2 light-emitting elements, m1>1, m2>1, and m1<m2, and
wherein at least one of the followings is satisfied:
|V3−V1|/|V1|<(m2−m1)/m1;
|V2−V4|/|V2|<(m2−m1)/m1; or
(|V3−V4|−|V1−V2|)/|V1−V2|<(m2−m1)/m1.
