3M Brightness Enhancement Films (BEF)
3M Brightness Enhancement Film II (BEF II) is a second-generation micro-replicated enhancement film that utilizes a prismatic structure to provide up to a 60% brightness gain. BEF II recycles diffuse light into the backlight and directs the light through the LCD, thereby providing increased brightness toward the viewer.
A single sheet provides up to 60% increase in brightness and two sheets crossed at 90° can provide up to 120% brightness increase. This increased brightness can be translated into power savings.
- Ideal for LCD displays in notebooks
