Polarizing plates are divided into two types: iodine-based and dye-based based on materials. The polarizing effect of iodine-based polarizing plates is better, but the degree of polarization decreases greatly under high temperature and high humidity conditions.

Flat panel displays are commonly used in PC (notebook and liquid crystal display) and non-PC fields ( Portable communication products, home video and audio products and industrial use products). As small as the electronic watch, mobile phone, tablet, and computer we carry in our hands...More

Flat panel displays are commonly used in PCs (notebooks and LCD monitors) and non-PCs ( Portable communication products, home video and audio products and industrial use products). As small as electronic watches, mobile phones, tablets, electronic computers, notebook computers, desktop LCD monitors, digital cameras, portable DVD; as large as industrial automation control panels, measuring instruments, televisions, and public inquiry systems, etc., all use polarizers of different grades.
