1. A display panel, comprising:
a base layer;
a plurality of dams, disposed on the base layer; and
a plurality of sub-pixels, disposed on the base layer in the dams and being in a one-to-one correspondence with the dams, wherein geometric figures of any two sub-pixels are congruent geometric figures;
in a first direction, a geometric figure obtained after any one of the sub-pixels is translated coincides with a geometric figure of a next sub-pixel adjacent to the sub-pixel;
in a second direction perpendicular to the first direction, a geometric figure obtained after any one of the sub-pixels is rotated by 180° coincides with a geometric figure of a next sub-pixel adjacent to the sub-pixel; and
each of the sub-pixels comprises a plurality of display regions, and a shape of an arrangement for the display regions in any one of the sub-pixels is same as a shape of a geometric figure of the sub-pixel in which the display regions are located;
wherein the sub-pixels comprise:
a plurality of first sub-pixels, each of the first sub-pixels comprising three first display regions;
a plurality of second sub-pixels, each of the second sub-pixels comprising three second display regions; and
a plurality of third sub-pixels, each of the third sub-pixels comprising three third display regions; and
colors of the first display regions, the second display regions, and the third display regions are different from each other;
wherein the geometric figure of each of the sub-pixels comprises a “└” shape with equal sides or a “┐” shape with equal sides.
