Background technique
The rapid development of display screen industry therewith, it is past that Organic Light Emitting Diode (abbreviation OLED) technology is that display screen is intended to
Narrow frame and the optimal selection that screen direction is developed comprehensively.The circularly polarized light that relatively traditional LED, OLED is generated can have no loss
By polaroid, light efficiency improves 100%, realizes lower power consumption and higher image definition and contrast.OLED can roll over
Folded bending, nearly 180 ° of visual angles have the advantages such as Flexible Displays and large area total colouring, almost can be applied to any display neck
Domain.
Present flexible screen is using being arranged film or graphene above OLED device to seal to OLED device
The technology of dress prevents steam and between oxygen passes through to improve the airtightness between film or graphene and the substrate of bottom
Gap, which penetrates into, corrodes luminescent layer organic material inside OLED device, it is necessary to be arranged among film or graphene and bottom substrate
UV glue, then UV irradiation makes its solidification sealing.
However the development of current OLED technology receives that the OLED organic luminescent coating service life is shorter and OLED encapsulating material
The limitation of the problems such as bending cracking.Because luminescent layer organic material is easy to chemically react with steam and oxygen in OLED,
Once airtightness is bad, luminescent layer organic material will fail in OLED.
Be currently used for OLED encapsulation glue selection less varieties, technique is single and performance is undesirable.UV glue OLED screen body
Using film or graphene, they are all the materials of the very strong polyhedral structure of orientation, with common acrylic ester type
Light-cured resin lacks affinity, can not form effective adhesive force.With OLED display technology make rapid progress development,
Its shape, thickness and colour system is all complicated constantly, and UV glue is caused to be more and more obvious using middle bonding agent solidification defect, solidification
Unevenly, porous and cured layer and the barrier layer OLED adhesive force are weak etc., so that steam and oxygen are easier to penetrate into through gap
To the inner seal region OLED, corrodes luminescent layer organic material, lead to OLED performance fast degradation, the lost of life.Currently, OLED
Screen develops to foldable rollable state, must just use and be cracked with outstanding flexibility, lower shrinkage, resist bending
OLED encapsulating material, however usually acrylic ester type light-cured resin strand gap is big, hardness is big, shrinks big and anti-tidal rip
Oxygen performance is poor, can not just be intended to foldable rollable direction suitable for OLED screen curtain and develop.
