Embodiment 1

[0043] see figure 1 , the present embodiment provides a polarizer 100 (hereinafter referred to as "polarizer 100") having a water-resistant nano-coating 1000, including sequentially pasted:

[0044] Water-resistant nano-coating 1000, used to resist water vapor and provide structural strength;

[0045] A first TAC film 2000 for providing protection;

[0046] PVA film 3000, used as a polarizing layer;

[0047] A second TAC film 4000 for protection;

[0048] PSA adhesive layer 5000 for providing bonding properties;

[0049] Release film 6000, used to provide isolation, filling and protection.

[0050] Wherein, the waterproof performance of the water-resistant nano-coating 1000 comes from the small gaps formed by the nano-scale particles, which make it difficult for water molecules to pass through.

[0051] Preferably, in this embodiment, the nano-particles in the water-resistant nano-coating 1000 have the same direction. Due to the improved arrangement of nanoparticles, the...

Abstract

The invention provides a polaroid with a water-proof nano-coating and a liquid crystal display provided with the same. The polaroid with the water-proof nano-coating comprises the water-proof nano-coating, a first TAC film, a PVA film, a second TAC film, a PSA adhesive layer, and a release film in sequence. The water-proof nano-coating, the first TAC film, the PVA film, the second TAC film, the PSA adhesive layer, and the release film are attached to one another. The water-proof nano-coatings is used for resisting water vapor and providing structural strength, the first TAC film is used for providing protection, the PVA film is used as a polarizer layer, the second TAC film is used for providing protection, the PSA adhesive layer is used for providing cohesive property, and the release film is used for providing isolation, padding, and protection. Because the water-proof nano-coating is arranged on the outside of the polaroid, the polaroid with the water-proof nano-coating and the liquid crystal display are not only water-proof, but also have advantages of resistance to scratching, anti-reflection, fingerprint-proofness and the like.

Description

technical field [0001] The invention relates to the technical field of polarizing devices, in particular to a polarizer and a liquid crystal display with a water-resistant nanometer coating. Background technique [0002] With the continuous development and progress of optical imaging technology, liquid crystal displays are widely used in various display fields because of their low space occupation rate and low energy consumption. The liquid crystal display controls the alignment direction of the liquid crystal molecules when the light from the light source passes through the liquid crystal layer through an electric field, and changes the transmittance to display images. The imaging of liquid crystal displays must rely on polarized light, and all liquid crystal displays are equipped with polarizers. [0003] The existing polarizer has poor water resistance, and water vapor easily enters into the polarizer and affects the polarizing PVA layer, resulting in durability failure....
