Introduction to APF (Advanced Polarizing Film)
3M’s APF (Advanced Polarizing Film) is an on-glass reflective polarizer that recycles unused light within the backlight system, boosting brightness, improving energy efficiency, and enabling thinner LCD module designs. Compared to traditional DBEF solutions, APF stands out for its superior wide-angle performance, higher integration, and better suitability for thin, high-efficiency display applications.
