Description
Technical field
The present invention relates to a kind of OLED polaroids, and in particular to a kind of flexibility OLED polaroids.
Background technology
At present, polaroid as the necessary part in organic light emitting diode display by called optical imaging.Polaroid makes
Derived from right polarization of light light, to increase the clarity of OLED display.
It is easily dazzling in the sun and can be caused due to light reflection can but the reflectivity of existing polaroid is all universal higher
The property read is very poor.Especially when applying common rotatory polarization piece on flexible OLED, existing common rotatory polarization piece is to steam and oxygen
Blocking capability it is very weak, and OLED is very sensitive to steam and oxygen, once penetrating into, may corrode organic function layer and electricity
Pole material, seriously affects the service life of device.
It would therefore be desirable to a kind of flexible OLED polaroids being especially improved, with solve existing polaroid reflectivity it is higher,
The problem of stopping steam and weaker oxygen ability.
The content of the invention
The defects of to overcome present in the prior art, now provide a kind of flexibility OLED polaroids, do not influencing flexible OLED
On the premise of light transmission, solve existing polaroid reflectivity it is higher easily it is dazzling, and stop steam and oxygen ability it is weaker
The problems such as.
To achieve the above object, a kind of flexibility OLED polaroids, including：
Lower adhering agent layer, alternating layer, release film layer and the upper adhering agent layer being sequentially formed on flexible OLED, its
In, alternating layer includes being alternately formed in the scattering layer and barrier layer on lower adhering agent layer.
Flexibility OLED polaroids of the invention further improvement lies in that, scattering layer and barrier layer are formed at by alternate cycle
On lower adhering agent layer, and the scattering layer in each alternate cycle is located on barrier layer.
Flexibility OLED polaroids of the invention further improvement lies in that, alternate cycle is more than or equal to two and is less than or waits
In ten positive integer.
Flexibility OLED polaroids of the invention further improvement lies in that, further include：The line being arranged on adhering agent layer
Polaroid, including protective layer and be arranged in protective layer polarisation；Wherein, the refractive index of scattering layer is more than line polarisation piece
Mean refractive index.
Flexibility OLED polaroids of the invention further improvement lies in that, forming the scattering material of scattering layer includes：SiNx or
TiO2。
Flexibility OLED polaroids of the invention further improvement lies in that, further include：The line being arranged on adhering agent layer
Polaroid, including protective layer and be arranged in protective layer polarisation.
Flexibility OLED polaroids of the invention further improvement lies in that, the mean refractive index of line polarisation piece is 1.48.
Flexibility OLED polaroids of the invention further improvement lies in that, the refractive index of barrier layer is in 1.40 to 1.50 scopes
It is interior.
Flexibility OLED polaroids of the invention further improvement lies in that, forming the barrier material of barrier layer includes：SiO2。
The beneficial effect of flexibility OLED polaroids of the invention is：Pass through the scattering layer and barrier layer being periodically alternatively formed
Strengthen polaroid and stop the ability of steam and oxygen, and preferably play effect anti-dazzle under sunlight, further improve encapsulation effect
Fruit.

Embodiment
For the benefit of to the understanding of structure of the invention, illustrate with reference to the accompanying drawings and embodiments.
Reference Fig. 1, is the structure diagram of existing OLED polaroids, as shown in Figure 1, current OLED polaroids substrates
All include two protective layers up and down, polarisation is provided between two protective layers, two stickers up and down are then formed under polarisation
Layer, release film layer is set between two adhering agent layers.As shown in Figure 1, whole polaroid is attached on OLED, is produced with this
Polarised light, strengthens the clarity of OLED entirety.But the ability of existing polaroid barrier steam and oxygen is relatively
It is weak, it cannot reach the effect for improving encapsulation OLED very well.Also, the reflectivity of existing polaroid is generally higher, in sunlight
Under be easy to cause it is dazzling.
With reference to Fig. 2, for the structure diagram of flexibility OLED polaroids of the invention, as shown in Fig. 2, to disclose one kind soft by the present invention
Property OLED polaroids, including：Lower adhering agent layer, alternating layer 1, the release film layer being formed at from the bottom to top successively on flexible OLED
And upper adhering agent layer.The main scattering layer 10 and barrier layer 12 by being alternately formed on lower adhering agent layer of this alternating layer 1
Form.Wherein, scattering layer 10 and barrier layer 12 are alternatively formed with some cycles, alternate periodicity more than or equal to
Two and the positive integer less than or equal to ten in the range of, also, within each cycle, scattering layer 10 is located on barrier layer 12.
Reference Fig. 3, is the effect diagram of scattering layer in flexibility OLED polaroids of the invention, as shown in figure 3, adding friendship
It is more than before not adding alternating layer 1 originally possessed mean refractive index in polaroid for the refractive index of the scattering layer 10 in layer 1
(about 1.48), scattering layer 10 can be by SiNx or TiO2Formed Deng material.The refractive index of barrier layer 12 was not with originally adding friendship
Mean refractive index for polaroid before layer 1 is close, and more barrier layers 12 then can be by SiO2Formed Deng material.When oled light from
When the relatively low barrier layer 12 of relative index of refraction injects refractive index higher scattering layer 10, the problem of just will not producing total reflection, with
The ability of this enhancing OLED scattering light extractions, achievees the purpose that to reduce polaroid reflectivity.And the propagation of changing section light whereby
Direction, so as to achieve the purpose that anti-glazing, can also see screen clearly in the sun.
Further, since the refractive index of barrier layer 12 and original mean refractive index phase for not adding polaroid before alternating layer 1
Closely, in this way, both can reach the effect for improving encapsulation, optical effect will not be produced.And further, barrier layer can be obstructed effectively
Steam and oxygen, prevent steam and oxygen from penetrating into inside OLED, avoid steam and oxygen corrosion OLED organic function layer and
Electrode material, improves device lifetime, so as to improve the sealing performance of flexible OLED.
The present invention is described in detail above in association with attached drawing embodiment, those skilled in the art can be according to upper
State and bright many variations example is made to the present invention.Thus, some details in embodiment should not form limitation of the invention, this
Invention will be used as protection domain using the scope that the appended claims define.
