Polyvinyl alcohol film for diffuser

Abstract

The invention relates to a polyvinyl alcohol membrane for the polarizing film, which is used to solve the problem of high-performance PVA film. The composition and weight of shares of the polyvinyl alcohol membrane: 10-30 units of PVA polymer, 5-25 units of plasticizer, 1-5 units of surfactant, 50 - 200 units of solvent. The PVA membrane has a high strength, good extension, which can be widely applied to liquid crystal display (LCD).

Description

technical field

[0001] The invention relates to a polyvinyl alcohol film, in particular to a polyvinyl alcohol film for a polarizer. Background technique

[0002] Polarizer is an important part of liquid crystal display (LCD). Due to its unique optical properties, it is also a sheet material similar to plastic sheet, which is easy to process and use. Therefore, it is used in daily necessities, industrial transportation, national defense and It has a wide range of applications in cutting-edge science and technology.

[0003] At present, the largest use of polarizers is for various types of liquid crystal display devices (LCDs). The application fields of this LCD have also expanded from small machines such as desktop calculators and watches in the early days to notebook computers and LCD monitors in recent years. devices, LCD color projectors, car navigation systems, LCD TVs, mobile phones, and measuring instruments used indoors and outdoors. If the polarizer has a defect, t...
