Problems solved by technology

[0007] Since the desiccant particles in the solid film are partially covered by the linker, the moisture and oxygen that penetrate into the package cannot be quickly and effectively absorbed by the desiccant in the solid film
In other words, the moisture and oxygen present in the initial packaging body and the low absorption performance of the desiccant particles will still damage the organic electroluminescent element to a certain extent; moreover, the organic electroluminescent element is a thin-fi

Abstract

The invention is a kind of sealing structure of the organic electric laser element and the manufacturing craft. It uses a multi-hole drier into the sealing structure of the organic electric laser element. The drier is produced through hydraulic drier configuration, foam generating process, and solidification craft. The drier is made up of solid hardened glue with form and several drier particles or power dispersed in the glue. The glue also may contain foam generating agent. The foams in the drier can enhance the water and oxygen absorption rate and the area, enhances the absorption efficiency of water and oxygen.

Description

technical field [0001] The present invention relates to a packaging structure of an organic light emitting device (Organic Light Emitting Device, OLED or Organic Electro luminescence, OEL) and its manufacturing process, and in particular to a device with a porous desiccant Packaging structure and manufacturing process of organic electroluminescence element. Background technique [0002] The information and communication industry has become the mainstream industry today, especially the development of various portable communication display products, and the flat panel display is the communication interface between people and information, so its development is particularly important. The technologies currently applied to flat-panel displays mainly include the following: plasma display (Plasna Display Panel, PDP), liquid crystal display (Liquid Crystal Display, LCD), inorganic electroluminescent display (Electro-luminescent Display), light-emitting diode (Light Emitting Diode (...
