Abstract
An Organic Light Emitting Diode (OLED) encapsulation method and structure are disclosed. The encapsulation method provides a thin film of lipophilicity in a fill region of an encapsulation cover. The lipophilicity of the thin film may attract the thermally curable fill adhesive of low viscosity, and therefore the fill adhesive in the fill region may spread to the corners of the fill region. After the encapsulation cover and an OLED substrate assembly are joined, the fill adhesive may completely fill up the space surrounded a dam adhesive between the encapsulation cover and the OLED substrate assembly, thereby preventing empty pockets formed at the corners and guaranteeing the encapsulation effect to the OLED device.
