Claim 8:
9. 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;
an intermediate adhesive layer; and
a surface layer, wherein the surface layer is stacked with the intermediate adhesive layer 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; and
wherein the substrate layer comprises a front surface for receiving projection images and a back surface facing away from the front surface, the first substrate comprises a first protrusion at an end of the first substrate that is located at the splicing seam, the second substrate comprises a second protrusion at an end of the second substrate that is located at the splicing seam, the first protrusion and the second protrusion protrude from the back surface, the intermediate adhesive layer comprises a first intermediate adhesive layer and a second intermediate adhesive layer, the first intermediate adhesive layer is adjacent to the first protrusion and bonded to the back surface of the first substrate, the second intermediate adhesive layer is adjacent to the second protrusion and bonded to the back surface of the second substrate.
