Process for eliminating static electricity of polaroid

Abstract

The invention discloses a process for eliminating the static electricity of a polaroid. The process comprises the following steps of: 1) selecting a quaternary ammonium salt cationic surfactant, preparing static electricity elimination liquid from the quaternary ammonium salt cationic surfactant and absolute ethyl alcohol in proportion, pouring the static electricity elimination liquid into a special container, making a mark, and avoiding contact with skin in the process, otherwise, washing the skin with clear water in time; (2) manufacturing a cleaning tool by using dust-free cloth and a special fixture, forbidding the exposure of edge opening of the fixture, so as to avoid scratches caused by direct contact between the fixture and the polaroid in a subsequent process; and (3) taking a supplied polaroid, removing inner and outer packages, flatly placing the polaroid on a working table, and confirming that a release film faces upward. The invention belongs to the technical field of displays. With the process for eliminating the static electricity of the polaroid adopted, the static electricity of the polaroid is reduced to be (-) 0.2 KV or below, and the phenomena of polaroid adhesion and polaroid connection do not occur in the polaroid machining process and before the attachment of the polaroid to a client.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a process for eliminating static electricity of a polarizer. Background technique [0002] Liquid crystal display is an active-matrix liquid crystal display driven by thin-film transistors (TFT). It mainly stimulates liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. [0003] Static electricity is extremely harmful to liquid crystal display (LCD) and other display industries. In addition to affecting the cleanliness of the product surface, it will also damage the integrated circuits in the module. As one of the main materials of LCD, polarizers are antistatic and destatic Research has never stopped.

[0003] Static electricity is extremely harmful to liquid crystal display (LCD) and other display industries. In addition to affecting the cleanliness of the product surface, it will also damage the integrated circuits in the module. As one of the main materials of LCD, polarizers are antistatic and destatic Research never stops

[0004] The basic structure of the polarizer includes: the middle PVA (polyvinyl alcohol), two layers of TAC (triacetyl cellulose), PSAfilm (pressure-sensitive adhesive), Release film (release film) and Protective film (protective film), currently The antistatic work of the polarizer is concentrated on the outer layer of TAC and the PSA pressure-sensitive adhesive layer. There is little mention of the release film and protective film as the intermediate process film, especially the release film layer, and the antistatic and antistatic properties of the polarizer The work often only focuses on the bonding process of polarizers and LCDs, and the manufacturing process of LCD modules, while ignoring the processing process of polarizers themselves, the friction of polarizer raw materials, especially sheets, during transportation, storage temperature and humidity The change of the release film and the difference in the surface resistivity of the protective film, it is easy to generate static electricity accumulation. Experiments have proved that when the static electricity of the polarizer reaches (-)0.5KV, the phenomenon of sticking and connecting sheets will occur, which will seriously affect the polarization. Film cutting, machine inspection and other processes reduce production efficiency and cause poor processing. In order to overcome the above difficulties, the purpose of the present invention is to provide a polarizer static elimination process, which reduces the static electricity of the polarizer to below (-)0.2KV, and achieves the polarizer. There will be no sticking or contiguous films during the processing and before the client is bonded
