The flat panel displays such as (OLED, OrganicLight-EmittingDiode) display gradually replace cathode-ray imaging
Manage (CRT, CathodeRayTube) display.Wherein, OLED have self-luminous, driving voltage is low, luminous efficiency is high, response when
Between short, clarity and contrast be high, nearly 180 ° of visual angles, use temperature range are wide, it can be achieved that Flexible Displays and large area is panchromatic shows
Many advantages, such as showing, and be widely used in mobile phone screen, computer monitor, full-color TV etc., it is known as being most to have by industry
The display device of development potentiality.
OLED has anode, organic luminous layer and the cathode being sequentially formed on substrate.Restrict OLED industry development most
Big problem and the greatest drawback of OLED are that the service life of OLED is shorter, and the reason for causing the OLED service life shorter mainly constitutes OLED device
The electrode and luminescent layer organic material of part in atmosphere pollutant, steam and oxygen it is all very sensitive, containing water
Vapour, oxygen environment in be easy to happen electrochemical corrosion, OLED device is damaged.Therefore, it is necessary to be carried out to OLED effective
Encapsulation prevents steam, oxygen from entering inside OLED.
OLED encapsulation mainly includes following methods: desiccant encapsulation, UV glue encapsulate (also known as Damonly encapsulation), UV
Glue and filling glue encapsulation (also known as Dam&Fill encapsulation), glass cement encapsulation (also known as Frit encapsulation) etc..Wherein, UV glue encapsulation technology
Be OLED encapsulation earliest be also most common technology, have a characteristic that without using solvent or use a small amount of solvent, reduce
Pollution of the solvent to environment；Energy consumption is few, low-temperature curable, suitable for the material sensitive to UV；Curing rate is fast, high-efficient, can
It is used in high-speed production lines, curing apparatus occupied area is small etc..But sealant used in the encapsulation of UV glue is organic material
Material, molecular gap is larger after solidification, using traditional OLED encapsulation method, due to sealant have bonding agent solidification defect, porosity,
Reasons, steam and oxygen are easier to infiltrate through inner seal region through gap with the binding force of substrate, encapsulation cover plate is weak etc.,
It comparatively fast degenerates so as to cause the performance of OLED device, the lost of life.
Therefore, by effectively being encapsulated to OLED, guarantee good leakproofness inside OLED device, be reduced as far as
The contact of OLED device and oxygen, steam in external environment, it is stable for the performance of OLED device and extension OLED to use the longevity
It orders most important.Some OLED usually pass through glue and connect the junction of cover board and substrate, and sealing effect is not Er Qielian very well
The intensity for meeting place is also poor.
