The 3M™ Dual Brightness Enhancement Film (DBEF) family of films are all reflective polarizers, in which light of one polarization is reflected and light of the other polarization is transmitted. 3M DBEF use 3M’s multi-layer optical technology for this polarized light management in which illumination from the backlight is recycled for greater efficiency and performance. All the films increase display brightness and can be used in conjunction with other 3M products such as 3M™ Brightness Enhancement Film (BEF) and 3M™ Enhanced Specular Reflector (ESR).   Add to cart
