Problems solved by technology

[0003] However, the reflectivity of existing polarizers is generally high, it is easy to dazzle in the sun and the readability is extremely poor due to light reflection
Especially when ordinary circular polarizers are used on flexible OLEDs, the existing ordinary circular polarizers have a weak barrier ability to water vapor and oxygen, while OLEDs are very sensitive to water vapor and oxygen, and once infiltrated, it may corrode organic functional layers and Electrode material, which seriously affects the life of the device

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0018] Such as figure 1 As shown, a flexible OLED polarizer includes a polarizer base layer 1, alternating layers 2 are respectively arranged on the upper and lower sides of the polarizer base layer 1, and a scattering layer 3, a barrier layer 4 and a protective layer 5 are arranged outside the alternate layer 2 in sequence. The layers are bonded by an adhesive, the surface of the scattering layer 3 has a micro-concave-convex structure, and the scattering material of the scattering layer 3 is titanium dioxide.

[0019] In this embodiment, the adhesive is pressure-sensitive adhesive, which has a good adhesive effect and will not affect the function of the flexible polarizer.

[0020] In this embodiment, the barrier material of the barrier layer 4 is silicon dioxide, and silicon dioxide is used as the barrier material, which has a good barrier effect....

Abstract

The invention relates to the technical field of polarizers, in particular to a flexible OLED polarizer. The flexible OLED polarizer comprises a polarizer base layer and is characterized in that an alternating layer is arranged on each of the upper side and lower side of the polarizer base layer, a scattering layer, a barrier layer and a protecting layer are sequentially arranged outside each alternating layer, the layers above are adhered through adhesives, the surface of each scattering layer is provided with a micro concave-convex structure, and the scattering material of the scattering layer is titanium dioxide. The flexible OLED polarizer has the advantages that the adhesives are pressure-sensitive adhesives which are good in adhering effect and do not affect the function of the flexible polarizer, a barrier material is silicon dioxide which is good in barrier effect, and the each protecting layer is 0.01-0.03mm in thickness; by the structure, a good protecting effect is achieved while polarizer thickness is not increased.

Description

technical field [0001] The invention relates to the technical field of polarizers, in particular to a flexible OLED polarizer. Background technique [0002] Currently, polarizers are well known as an essential part of OLED displays. Polarizers polarize natural light to increase the clarity of OLED displays. [0003] However, the reflectivity of existing polarizers is generally high, which is easy to be dazzled in sunlight and has extremely poor readability due to light reflection. Especially when ordinary circular polarizers are used on flexible OLEDs, the existing ordinary circular polarizers have a weak barrier to water vapor and oxygen, while OLEDs are very sensitive to water vapor and oxygen, and once infiltrated, it may corrode organic functional layers and The electrode material seriously affects the life of the device. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies in the prior art and provide a flexible OLE...
