Claim 0:
1. A screen splicing structure, comprising:
a substrate layer comprising a first substrate and a second substrate, wherein the second substrate and the first substrate are spliced and form a splicing seam at a splicing joint, wherein the substrate layer comprises a front surface for receiving projection images and a back surface facing away from the front surface, the front surface is provided with a first optical functional material layer and an optical functional material default zone, the optical functional material default zone is arranged along the splicing seam;
an intermediate adhesive layer arranged in the optical functional material default zone; and
a surface layer comprising a bonding surface and an outer surface that face away from each other, and a side surface connecting the bonding surface with the outer surface, wherein the surface layer is stacked with the intermediate adhesive layer via the bonding surface and is bonded to the substrate layer through the intermediate adhesive layer, the surface layer covers the splicing seam, and a peeling strength between the surface layer and the substrate layer is greater than or equal to 1000 gf/inch, the outer surface is provided with a second optical functional material layer, and the second optical functional material layer has a same optical effect as the first optical functional material layer.
