3M™ Dual Brightness Enhancement Film (DBEF) is a family of polymer-based multilayer optical films that have polycarbonate laminated to both sides that manage the polarization output of light from LCD backlights. It is a reflective polarizer film that improves polarization efficiency by transmitting one polarization state and reflecting the other, recycling light back into the system, which increases brightness over a wide viewing angle. The increase in efficiency enabled by 3M polarization control can be used to offset key variables like energy consumption and thermal load in LCD applications.

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).
