The "GB/T 33049-2016 Method for Determination of Optical inspection film coating adhesion for polarizers" standard specifies the method for determining the adhesion of polarizers for liquid crystal displays and related Optical inspection film coatings. The standard is suitable for evaluating the adhesion strength between Optical inspection film coatings and substrates to ensure the Stability and Reliability of coatings during use. The test method mainly refers to the cross-cut test standard in "GB/T 9286". This standard provides an important technical basis for polarizer manufacturing and quality control, which helps to improve the durability and performance of products.
