The main material of photon curtain is PET, which is different from PVC used in traditional curtains. Photonic curtain has four layers: reflective layer, imaging layer, microlens combination layer and optical light distribution layer. The function of photon curtain is to improve the reflectivity of projected light, and its gain can reach 2. 1, which is higher than that of traditional curtain, and the natural color performance will be more realistic. The contrast effect of brightness is better than that of white plastic curtain, the viewing angle is larger than that of light-proof curtain, and the light uniformity is the same as that of soft white curtain.
