3M™ Advanced Polarizing Film (3M APF) is a family of on-glass reflective polarizer films, laminated to the rear absorbing polarizer.
3M™ Advanced Polarizing Film (3M APF) is a family of multi-layer optical films with reflective polarizers designed to be laminated within the backlight of a display. Through polarization recycling, 3M APF reflects on polarization of light into the backlight where it is repolarized and recycled, providing increased brightness with a wide viewing angle.
