  • Patent number: 8703280
    Abstract: Provided is a high-shielding reflective film, and its manufacturing method. This film is fabricated from an optical reflective film and a polarizer. The optical reflective film and the polarizer are combined by a means of a specific scheme. The optical reflective film is formed by stacking multiple layers of dielectric optical interference films with different materials. The optical reflective film particularly applies a principle of optical interference to reflect the most of the incident light, and allow some transmission. The polarizer is to absorb half of the incident light, and allow the other half to pass through. Since the characteristics of reflection between the reflective film and the polarizer are different, the reflectance difference therefor may increase. By which, the high-shielding reflective film achieves a one-way mirror with anti-peep effect since it substantially increases the reflectance difference among the incident lights from the various directions.
