龍幕采用镍、银、钛、金、铟、铜、铝等多种贵金属，并采用磁场控制的方式让金属离子均匀的溅射到光学级的PET基材上，沉积成金属镀膜层。以持久反射隔热的出色性能而著称。具有高清晰、高隔热、高稳定、低内反光、色泽纯正、使用寿命长等众多特点。

The dragon screen uses a variety of precious metals such as nickel, silver, titanium, gold, indium, copper, aluminum and other precious metals, and uses the magnetic field control method to make the metal ions uniformly sputtering to the optical grade pet substrate, depositing a metal coating layer. Noted for the excellent performance of persistent reflection heat insulation. It has many characteristics such as high clearness, high heat insulation, high stability,  never fading, long service life, etc.
