The LCD panel needs printing ink of various colors printed on the surface, the printing ink is generally printed on the back surface of a polarizer of the LCD panel through silk screen printing, and then a layer of polarizer, a PE protective film or a PET protective film is attached to protect the silk screen printing ink. However, the protective film may cause creases and scratches during the process of turnover or transportation, the single PE or PET protective film may be torn off when assembling the finished module, resulting in direct exposure of ink to contact with the module case, which is likely to cause ink scratches, and the additional attachment of a polarizer layer with higher cost is an indispensable optical device of the liquid crystal display panel for eliminating glare and improving vision. The basic structure of the polarizer includes: the most central PVA (polyvinyl alcohol), two layers of TAC (cellulose triacetate), PSAfilm (pressure sensitive adhesive), Releasefilm (release film) and protectibefilm (protective film). The PVA layer plays a role in polarization, but is extremely easy to hydrolyze, and in order to protect the physical characteristics of the PAV 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 order to adhere a glass substrate of a liquid crystal display, a PSA with a certain thickness needs to be coated on one side of a polarizer original plate, and a release film for protecting the PSA before attachment is compounded; and a protective film for protecting the polarizer is laminated on the other side.

In the protection film of the LCD surface silk screen printing ink disclosed in the Chinese utility model patent application publication No. CN206406549U, though, this protection film can protect silk screen printing ink by outside fish tail, however, this protection film of LCD surface silk screen printing ink exists and is difficult to install, and the edge of protection film produces the mar to silk screen printing ink easily during the installation, and the radiation protection ability is poor, and the easy ageing shortcoming that drops easily of viscose.
