AI Technical Summary

Problems solved by technology

OLEDs have very high barrier requirements for water and oxygen. The current epoxy resin sealing technology cannot meet the required requirements, which limits the service life of OLEDs.
Also, this epoxy sealing technique cannot be used on flexible flat panel displays due to the hardness of glass or metal

Description

technical field [0001] The invention relates to the technical field of optoelectronics, in particular to a thin film package, an optoelectronic device and a packaging method thereof. Background technique [0002] Optoelectronic technology uses the characteristics of photons and electrons to realize the conversion, transmission and processing of information and energy through a certain medium. It has a wide range of applications and has penetrated into various fields of modern technology and life. The core of optoelectronic technology is optoelectronic devices, which are devices that can convert signals and energy between optoelectronics, electro-optics, and electro-optics. In optoelectronic devices, especially organic electroluminescent devices (OLEDs), the organic functional layers in their components are very sensitive to water, oxygen, etc., and easily react with water or oxygen to form black spots that do not emit light. Encapsulation techniques are therefore required t...
