An organic light-emitting device, comprising:
- a base substrate, an organic light-emitting element provided on the base substrate and an encapsulation structure for encapsulating the organic light-emitting element, wherein
- the encapsulation structure comprises a fluorescent material, and the organic light-emitting element emits a first light, and the fluorescent material is excited by the first light to generate a second light;
- the encapsulation structure comprises a cover plate and a filling layer filled between the cover plate and the organic light-emitting element, and the filling layer comprises the fluorescent material;
- the encapsulation structure further comprises an inorganic protection layer provided between the filling layer and the organic light-emitting element;
- and
- the organic light-emitting device further comprises a sealant between the cover plate and the base substrate, the sealant surrounds the organic light-emitting element, the filling layer and the inorganic protection layer, and an end of the inorganic protection layer contacts an inner wall, facing the organic light-emitting element, of the sealant.
A preparation method of an organic light-emitting device, comprising:
- providing a base substrate;
- forming an organic light-emitting element on the base substrate, wherein the organic light-emitting element emits a first light;
- encapsulating the organic light-emitting element by using an encapsulation structure, wherein the encapsulation structure comprises a fluorescent material, and the fluorescent material is excited by the first light to generate a second light, wherein
- the encapsulation structure comprises a cover plate and a filling layer filled between the cover plate and the organic light-emitting element;
- and
- the encapsulating the organic light-emitting element by using the encapsulation structure comprises:
- coating a sealant material at edges of the cover plate, mixing the fluorescent material with a desiccant, and coating the fluorescent material and the desiccant mixed with each other on the cover plate inside the sealant material;
- bonding the cover plate with the base substrate;
- and
- solidifying the sealant material and the desiccant to form a sealant and the filling layer.
