Background

The polaroid is called as a polaroid, the imaging of the liquid crystal display is dependent on polarized light, all liquid crystals have front and rear polaroids which are tightly attached to liquid crystal glass to form the liquid crystal plate with the total thickness of about 1mm, and the polaroid is a lens which is generally recognized as being most suitable for driving. The light is partially polarized when reflected by the surface of the object to produce glare. The reverse effect of glare-enhancing brightness, weakening color saturation; the outline of the object becomes fuzzy, and the eyes are tired and uncomfortable. The iodine-based polarizer is manufactured according to the polarization principle of light, has the special function of effectively eliminating glare, is easy to obtain the optical characteristics of high transmittance and high polarization degree, and has poor high-temperature and high-humidity resistance. The dye-based polarizer is not easy to obtain the optical characteristics of high transmittance and high polarization degree, but has better high temperature and high humidity resistance, and the basic structure of the polarizer comprises: the most central PVA (polyvinyl alcohol), two layers of TAC (cellulose triacetate), PSA film (pressure sensitive adhesive), Release film (Release film) and Protective film (Protective film). The polarizing film is made of a PVA layer, but the PVA layer is very easy to hydrolyze, and in order to protect the physical characteristics of the polarizing film, a (TAC) film with high light transmittance, good water resistance and certain mechanical strength is compounded on each of two sides of the PVA for protection, so that the original polarizer plate is formed. In the production of common TN type LCD polaroids, according to different use requirements, one side of a polaroid original plate is coated with PSA with a certain thickness, and an isolating film for protecting the PSA is compounded; and a protective film, a reflective film and a semi-transparent and semi-reflective adhesive layer film are respectively compounded on the other side according to the product type, so that a finished polaroid product is formed.
