Embodiment Construction

[0020] In order to facilitate the understanding of the structure of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.

[0021] refer to figure 1 , is a structural schematic diagram of an existing OLED polarizer, such as figure 1 As shown, the substrates of current OLED polarizers all include upper and lower protective layers, and polarizers are arranged between the two protective layers, and two upper and lower adhesive layers are formed under the polarizers. type film. Depend on figure 1 It can be seen that the entire polarizer is attached to the OLED to generate polarized light and enhance the overall clarity of the OLED. However, the ability of the existing polarizers to block water vapor and oxygen is relatively weak, and it has been unable to achieve the effect of perfect packaging OLED. Moreover, the reflectivity of existing polarizers is generally high, which easily causes glare in sunlight. ...

Abstract

The invention provides a flexible OLED polarizer, comprising a lower adhesive layer, alternating layers, a release film layer and an upper adhesive layer formed on the flexible OLED sequentially from bottom to top, and the alternating layers include alternately formed on the lower adhesive layer above the scattering layer and the barrier layer. The invention solves the problem that the existing polarizers have high reflectivity and is easy to dazzle, and further strengthens the ability to block water vapor and oxygen, so as to better improve the packaging effect.

Description

technical field [0001] The invention relates to an OLED polarizer, 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. [0004] Therefore, we need a specially improved flexible OLED polarizer to solve the problems of high reflectivity and weak ability to block water vapor and oxygen...
