1. A display panel, comprising:
a first display region and a second display region, wherein:
the second display region includes a plurality of light-transmitting hole combination regions, wherein:
at each light-transmitting hole combination region, at least two light-transmitting hole groups surround a central light-transmitting hole;
each light-transmitting hole group includes a plurality of light-transmitting holes;
a boundary line of each light-transmitting hole is a closed arc; and
centers of all light-transmitting holes in each light-transmitting hole group are distributed along a ring shape, wherein different light-transmitting hole groups have different ring sizes, different ring shapes corresponding to the at least two light-transmitting hole groups share a common center with a center of the central light-transmitting hole, and each of at least two ring shapes, corresponding to the at least two light-transmitting hole groups, is a circle or an ellipse;
all light-transmitting holes, except the central light-transmitting hole, in the second display region are distributed along a ring shape, and there is no light-transmitting hole between two adjacent light-transmitting hole combination regions; and
the second display region further includes a plurality of pixels and a plurality of pixel drive circuits, wherein:
pixel drive circuits in the plurality of pixel drive circuits used for driving pixels in the light-transmitting hole combination regions are first pixel drive circuits;
at least a portion of the first pixel drive circuits is at a region outside the light-transmitting hole combination regions; and
the pixels in the light-transmitting hole combination regions are exclusively disposed between the at least two light-transmitting hole groups and between the central light-transmitting hole and one of the at least two light-transmitting hole groups directly adjacent to the central light-transmitting hole in the second display region.
