Abstract
The utility model discloses an organic light emitting diode (OLED) glass packaging device and belongs to the manufacturing technical field of organic electroluminescence devices, which comprises a glass substrate and a packaging cover arranged on the glass substrate. One side of the packaging cover, opposite to the glass substrate, is provided with a concave surface filled with a drying agent. The concave surface of the packaging cover is sequentially provided with a first groove, a second groove and a third groove from inside to outside. The first groove, the second groove and the third groove are orderly filled with packaging adhesive, the drying agent and packaging adhesive respectively. According to the technical scheme of the utility model, due to the adoption of the three grooves on the packaging cover, the phenomena that might occur during the packaging process in the prior art, such as the endosmosis of UV adhesive and the leakage of packaging adhesive, can be avoided. Meanwhile, the device is better in water and oxygen absorption capacity around the packaging cover.
Description
Technical field
The utility model belongs to has electromechanics to luminescent device manufacturing technology field, is specifically related to a kind of OLED glass packaging device.
Background technology
General encapsulation process comprises steps such as cap pre-treatment, hygroscopic agent add, coating frame glue, contraposition applying, illumination curing, sliver.Cap mainly is divided into crown cap and glass cover two big classes, crown cap handling ease and have optimized hydrone and block ability, thermal conduction characteristic and electric screen.The glass packaging lid is mainly considered the problem that whether produces microcrack, because microcrack is difficult for discovering, after being subjected to external force collision, microcrack expansion easily makes cap break.
Studies show that compositions such as airborne steam and oxygen are very big to the life-span influence of organic electroluminescence device (OLED).The cap pre-treatment mainly is to remove steam and the pollutant be adsorbed on the surface, influences device lifetime to avoid in the future desorption, and in order further to avoid because the steam desorption in cap surface or the framework must add hygroscopic agent.Recently, the trend of oriented thin-film package development.Thin-film package does not need cap and frame glue, can reduce thickness and the quality of device, and can save cost.
What development was best at present is the Barix thin-film encapsulation layer of Vitex Systems company exploitation, and it is equivalent to the effect of a glass to the permeability of moisture and oxygen.It is to be formed by stacking in a vacuum by polymer and ceramic membrane, and gross thickness only is 3 microns, and this encapsulation can directly be added in moisture and the oxygen insulation blocking that realizes on the OLED display OLED.
Good encapsulation is to obtain the stable the most basic requirement of OLED device, and how to reduce cost with the integration of panel processing procedure, is the important consideration factor that determines to use any encapsulation technology material and facility.
The utility model content
