Embodiment Construction

[0009] see figure 1 and figure 2 , the present invention proposes a kind of reusable three-dimensional polarizing glasses polarizer, which comprises a first protective film 1, an anti-scratch triacetate cellulose (TAC) film 2, a phase difference film 3, an anti-scratch polarizing film 4 and a second protective film 5 . The above layers are compounded together by a compound machine.

[0010] First, the definitions of the terms and symbols in the specification of the present invention will be explained.

[0011] (1) The symbol "nx" refers to the refractive index in the direction that provides the maximum in-plane refractive index (ie, the direction of the slow axis), and the symbol "ny" refers to the direction perpendicular to the slow axis (ie, the fast axis) in the same plane. direction) in the refractive index. The symbol "nz" refers to the refractive index in the thickness direction. Moreover, for example, the expression "nx=ny" not only refers to the case where nx and...

Abstract

The invention provides a reusable three-dimensional (3D) polarized glass polarizer and glasses using the same. The polarizer comprises a protective film, a scratch resistant cellulose triacetate (TAC) film, a retardation film, a scratch resistant polarizing film and a protective film in turn. An absorption axis of the scratch resistant polarizing film and a slow axis of the retardation film form an angle between 40 and 50 degrees or an angle between 130 and 140 degrees. The reusable three-dimensional (3D) polarized glass polarizer can effectively be prevented from scratching, and the hardness effect of the scratch resistance can reach more than 2H to prolong the service life of a product.

Description

technical field [0001] The invention relates to a reusable three-dimensional (3D) polarized glasses polarizer and glasses using the polarizer. The polarizer and the glasses can effectively prevent scratches, scratches and scratches during use. Background technique [0002] The polarizer of ordinary polarized glasses and the glasses using the polarizer of the polarized glasses are very easy to use due to dust or other dirt on the surface of the polarizer, which will cause scratches on the surface of the polarizer when wiping and affect the use effect. And the glasses using the polarizer of the polarized glasses can only be used once, which greatly wastes resources and costs. And this problem has not been solved all the time. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the problem that the polarizer of the existing polarized glasses and the glasses using the polarizer are easily scratched when wiping, resulti...
