Claim 16:
17. A display panel, wherein the display panel comprises:
a back board;
a plurality of light boards, the plurality of light boards being disposed on the back board, the light board comprising a plurality of light beads arranged in an array, and a first substrate and a second substrate disposed in a stack; the second substrate is stacked with the first substrate on a side of the first substrate, the first substrate comprises a stacking region stacked with the second substrate and a periphery region exceeding the second substrate, periphery regions of two adjacent plurality of light boards are stacked with the plurality of light boards to form a splicing region, and a distance between two columns of the plurality of light beads on two sides of the splicing region is within a preset range,
wherein the back board comprises a plurality of first reinforcing ribs arranged at intervals in a vertical direction and a plurality of second reinforcing ribs arranged at intervals in a horizontal direction, and the first reinforcing ribs and the second reinforcing ribs are arranged perpendicular to one another on a back side of the back board; a hollow structure is formed between the first reinforcing ribs and the second reinforcing ribs that are intersecting, and edge regions in the plurality of light boards are connected to the first reinforcing ribs or the second reinforcing ribs; the second substrate in each of the plurality of light boards is arranged in the hollow structure, so that a distance between two adjacent columns of the plurality of light beads spliced at the first reinforcing ribs or the second reinforcing ribs is within a preset range, and the two adjacent columns of the plurality of light beads on two sides of the splicing region are flush with each other in a splicing direction.
