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.
We combine functional layers to create one powerful solution.
*Cross section representation not to scale
Films with polarization control from 3M transmit the polarization of light that an LCD uses and reflect the polarization state it doesn‘t back into the backlight where it bounces and returns. Some of this light has changed polarization and is transmitted to the LCD, resulting in less wasted light and a more efficient display.
3M™ Dual Brightness Enhancement Film is a loose film versus solutions that are directly laminated to an LCD panel.
Did you know select 3M™ Dual Brightness Enhancement Film products are made with recycled plastics? That means more sustainable screens are possible when you choose 3M.
