1. A sealant structure, wherein the sealant structure comprises a plurality of adhesive strips, and the adhesive strips overlap end to end to form a closed loop defining a closed area;
wherein one of two adjacent adhesive strips of the adhesive strips is provided with an overlap region and a non-overlap region adjacent to the overlap region, the overlap region is disposed at at least one end of the one of the two adjacent adhesive strips, and a width of the overlap region is less than or equal to one third of a width of the non-overlap region; and
wherein in a direction of a length of the other of the two adjacent adhesive strips, an end of the other of the two adjacent adhesive strips overlapping with the overlap region of the one of the two adjacent adhesive strips protrudes from an outer edge of the non-overlap region of the one of the two adjacent adhesive strips, and the outer edge of the non-overlap region of the one of the two adjacent adhesive strips is away from the closed area;
wherein at least one of the adjacent adhesive strips is a cutout adhesive strip comprising at least one rectangular cutout defined in an inner side of the end of the cutout adhesive strip in the overlap region such that the width of the overlap region of the cutout adhesive strip is less than the width of the non-overlap region of the cutout adhesive strip, wherein the inner side of the cutout adhesive strip faces the other one of the adjacent adhesive strips.
