[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] An OCA adhesive structure for a circular wearable product, referring to Figure 1 and Figure 2 The OCA adhesive body 10 includes a bonding portion 11 and a tearing portion 12. The bonding portion 11 is used for bonding and fixing the display screen and the cover plate, and the tearing portion 12 is used for tearing off the bonding portion 11 after bonding.

[0026] Reference Figure 2 The size of the fitting part 11 is adapted to the size of the display screen, and the fitting part 11 is circular. The fitting part 11 is covered with OCA optical glue, and the OCA optical glue is solid. The tearing part 12 is arranged along the outer circumferential direction of the fitting part 11, and the tearing part 12 and the fitting part 11 are integrally formed. The tearing part 12 is not covered with OCA optical glue, and the OCA glue body 10 is polygonal. The fitting part 11 and the tearing part 12 together form a polygonal OCA glue body 10. The entire periphery of the tearing part 12 is polygonal, and the fitting part 11 is an inscribed circle of the tearing part 12. The tearing part 12 arranged in a polygonal shape facilitates the tearing off of the fitting part 11 after bonding.
