Abstract

The invention discloses a composition for packaging an optoelectronic device, a packaging structure and the optoelectronic device. The composition comprises 10%-70% of a photocurable monomer, 10%-70%of a monofunctional or trifunctional silicon-containing monomer; and 0.5%-10% of an initiator, using a silicon-containing monomer, on one hand, due to the fact that the deformation capacity of a Si-O-Si chain segment of the silicon-containing monomer is high, when the composition is impacted by force, the silicon-containing monomer can play a role in stress dispersion, internal stress is reduced,and the mechanical property of the organic packaging composition is improved; on the other hand, the thermal performance and the hydrophobic performance of the organic packaging composition can be effectively improved, and the service life of the device can be effectively prolonged when the organic packaging composition is used for thin film packaging of photoelectronic devices.

Description

technical field [0001] The invention belongs to the technical field of organic thin films, and in particular relates to a composition for packaging an optoelectronic device, a packaging structure and an optoelectronic device. Background technique [0002] With the development of science and technology, the upgrading of electronic products is also changing with each passing day, and many display devices have also changed from bulky and rigid to light and thin, foldable and bendable. Part of the performance and life of the display device is determined by its own characteristics, and the other part is guaranteed and extended by the external packaging protection. In the traditional packaging technology, the substrates used are rigid materials (such as: steel plate, acrylic, glass, ceramics and other hard materials), which lack flexibility and cannot fully meet the market demand. [0003] In Barix's Thin Film Encapsulation Technology (TFE), the inorganic barrier film will have d...
