Provided are an OLED encapsulation structure and an OLED encapsulation method; said OLED encapsulation structure comprises an encapsulation cover panel (1), a substrate (2), an OLED device (21), a desiccant (11) located at the periphery of the OLED device (21) and disposed on the encapsulation cover panel (1), and a sealant (12) located at the periphery of the desiccant (11) and bonded to the encapsulation cover panel (1) and the substrate (2); a circular groove (103) is disposed at the periphery of the region of the encapsulation cover panel (1) corresponding to the OLED device (21); the periphery of said groove (103) is provided with a plurality of circular raised/recessed structures (101); the desiccant (11) is arranged inside the groove (103); the sealant (12) is arranged between the raised/recessed structures (101) and the substrate (2). The OLED encapsulation structure has improved bonding strength between the encapsulation cover panel and the substrate, has a reduced distance between the encapsulation cover panel and the substrate, and effectively blocks the penetration of moisture and oxygen. |
