[0002] Polarizing film bending is a specific manufacturing process, which is mainly used to bend the plane polarizing film into the desired shape by heating and shaping. Polarizing film (also known as polarizer, polarizing film) is an optical element that can convert natural light into polarized light. It controls the direction and transmission of light waves by selectively allowing light waves of a specific polarization direction to pass through, while blocking or weakening light waves of other polarization directions. Polarizing film is usually composed of a multilayer film composite, and its core film material is polyvinyl alcohol film (PVA), which is responsible for realizing the polarization function. Polarizing film is widely used in liquid crystal display panels, polarized sunglasses, filters for photographic equipment and other fields. It is an indispensable material for improving display effects, protecting eyes, and controlling light quantity.
