3M™ Dual Brightness Enhancement Film (DBEF)



3M Dual Brightness Enhancement Film (DBEF) is a thin multi layer polarizer that provides both ant-glare as well as increased brightness to your screen. DBEF uses a process called polarization recycling that reflects unused light into the backlight and converts some of it back into useable light.

We slit in rolls or die-cut to your exact specifications.
