1. A display panel, comprising a display region, wherein at least a portion of the display region is a transparent display region;
wherein the transparent display region comprises a plurality of sub-regions, the plurality of sub-regions are arranged in an array and have a same shape and a same area, and a sub-region of the plurality of sub-regions comprises a first side and a second side which are adjacent to each other, wherein a first side of a sub-region also serves as a side of an adjacent sub-region in a first direction, and a second side of the sub-region also serves as a side of an adjacent sub-region in a second direction, the first direction intersects with the second direction, and the first direction intersects with the first side; and
wherein the sub-region comprises a non-light-transmissive region and a light-transmissive region, light-transmissive regions in the plurality of sub-regions have a same shape, a distance between a center of the light-transmissive region and a first side of a sub-region where the light-transmissive region is located is d1, a distance between the center of the light-transmissive region and a second side of the sub-region where the light-transmissive region is located is d2, and at least two of the plurality of sub-regions have at least one of different di or different d2;
wherein light-transmissive regions of the plurality of sub-regions have a same area;
wherein each of the plurality of sub-regions and each of the light-transmissive regions are rectangular in shape, and at least two adjacent bezel regions of the sub-region comprise the non-light-transmissive region;
wherein a first side of the light-transmissive region is adjacent to and parallel to the first side of the sub-region, the first side of the light-transmissive region has a length of d11, the first side of the sub-region has a length of d21, a second side of the light-transmissive region is adjacent to and parallel to the second side of the sub-region and has a length of d12, and the second side of the sub-region has a length of d22;
wherein d11<d21, d12<d22, d12/2≤d1≤d22−d12/2, and d11/2≤d2≤d21−d11/2; and
wherein d21−d11<0.1×d21, and d22−d12<0.1×d22;
wherein a maximum difference value between d1 in two sub-regions is d1max, a maximum difference value between d2 in two sub-regions is d2max, the light-transmissive region in the sub-region has a maximum size of D1 in the first direction, and the light-transmissive region in the sub-region has a maximum size of D2 in the second direction; and
wherein d1max<0.1×D2, and d2max<0.1×D1.
