1. A display panel, comprising a first display area, a second display area, and a transition display area between the first display area and the second display area, wherein:
the first display area includes a plurality of first sub-display areas, the second display area includes a plurality of second sub-display areas, and the transition display area includes at least one sub-transition area;
a first sub-display area of the plurality of first sub-display areas, a second sub-display area of the plurality of second sub-display areas and a sub-transition area each consists of two blue light-emitting elements, two red light-emitting elements, and four green light-emitting elements; and
number of pixel circuits for driving each light-emitting element in one of the at least one sub-transition area is greater than number of pixel circuits for driving each light-emitting element in one of the plurality of first sub-display areas and is smaller than number of pixel circuits for driving each light-emitting element in one of the plurality of second sub-display areas, wherein light-emitting elements in the first display area are driven by pixel circuits in the first display area, wherein:
in the second sub-display area, one pixel circuit is electrically connected exclusively to one light-emitting element of a same color;
the light-emitting elements include first light-emitting elements, second light-emitting elements and third light-emitting elements;
the sub-transition area includes at least one type of transition light-emitting elements and at least one type of non-transition light-emitting elements, the transition light-emitting elements are selected from one or two types of the first light-emitting elements, the second light-emitting elements and the third light-emitting elements, and the rest types of light-emitting elements are non-transition light-emitting elements;
an arrangement of the transition light-emitting elements includes: number of transition light-emitting elements in the sub-transition area driven by one pixel circuit is equal to number of transition light-emitting elements in the first sub-display area driven by one pixel circuit, and is greater than number of transition light-emitting elements in the second sub-display area driven by one pixel circuit; and
an arrangement of the non-transition light-emitting elements includes: number of non-transition light-emitting elements in the sub-transition area driven by one pixel circuit is smaller than number of non-transition light-emitting elements in the first sub-display area driven by one pixel circuit and is equal to number of non-transition light-emitting elements in the second sub-display area driven by one pixel circuit.
