Description

Technical Field

[0001] The utility model belongs to the technical field of lens structures, and particularly relates to an anti-fouling 3D polarizer. Background Technique

[0002] The polarized 3D technology is currently widely used in commercial cinemas and other high-end applications. In terms of technical methods, it is the same as the shutter type. The difference is that it is passive reception, so it is also called passive 3D technology. The cost of auxiliary equipment is relatively low, but the requirements for output equipment are relatively high. Therefore, it is very suitable for places such as commercial cinemas that need a large number of audiences.

[0003] Existing 3D glasses mostly use polarized lenses. During use, polarized lenses are easily affected by external oil stains and sweat, resulting in lens contamination, thus affecting their functional use. There is a way to set an anti-fouling layer of fluoride on the surface of polarized lenses. However, the existing fluoride layer will increase the reflectivity of polarized lenses, affecting the light transmittance. At the same time, the bonding strength between the fluoride layer and the polarized lens is insufficient, and the fluoride layer is prone to peeling off during long-term use, affecting its anti-fouling performance. Content of the Utility Model

[0004] In view of the above technical problems, the utility model provides an anti-fouling 3D polarizer to solve the problems that the fluoride layer of existing polarized lenses affects the light transmittance and is prone to peeling off. The anti-fouling 3D polarizer has low light reflection and a long service life.

[0005] The utility model provides an anti-fouling 3D polarizer, which includes a transparent base layer, a polarization film layer, an anti-reflection layer, a buffer layer and an anti-fouling layer. The polarization film layer is located on the surface of the transparent base layer. The anti-reflection layer is on the surface of the polarization film layer facing away from the transparent base layer. The buffer layer is located on the surface of the anti-reflection layer facing away from the polarization film layer. The anti-fouling layer is located on the surface of the buffer layer facing away from the anti-reflection layer. The buffer layer is a polyacrylate layer, the anti-reflection layer is an inorganic material layer, and the anti-fouling layer is a fluoride layer.

[0006] Further, the anti-fouling 3D polarizer is an arc-shaped sheet structure.

[0007] Further, the anti-reflection layer includes a plurality of high refractive index layers and a plurality of low refractive index layers, and the plurality of high refractive index layers and the plurality of low refractive index layers are arranged alternately one by one.

[0008] Further, the high refractive index layer is niobium oxide, and the low refractive index layer is silicon dioxide.

[0009] The anti-fouling 3D polarizer is provided with an anti-reflection layer and an anti-fouling layer. The anti-fouling layer has a good ability to resist oil adhesion, and the anti-reflection layer can play a good role in reducing the light reflectivity, so that the anti-fouling 3D polarizer has a higher light transmittance and reduces the influence of the anti-fouling layer on the light transmittance. At the same time, in order to improve the adhesion of the anti-fouling layer, a buffer layer is provided between the anti-reflection layer and the anti-fouling layer. The buffer layer is selected from polyacrylate layers, and polyacrylate has good bonding strength for both the inorganic material anti-reflection layer and the fluoride anti-fouling layer, thus avoiding the peeling off of the anti-fouling layer and improving the service life.
