Brightness Enhancement Films
Brightness Enhancement Films These are transparent optical films that increase LCD brightness through improved management of the existing light. 3M™ Brightness Enhancement Film (BEF) and (DBEF) are recycling, light management films, that are used to increase the brightness of backlights used in liquid crystal displays (LCD). Pronat offer 3M BEF, DBEF, ESR, Clarex difuseres, Luminit – LSD- Ligth Shape Diffusers.
BEF – Vikuiti™ Brightness Enhancement Films:
These are transparent optical films that increase LCD brightness through improved management of the existing light.
Vikuiti™ Brightness Enhancement Film III:
A micro-replicated prism film, which utilizes a random prism pattern that helps eliminate wet-out and reflective moiré while directing light toward the on-axis viewer of a liquid crystal display. A single sheet provides up to 59% increase in brightness and can be combined with many other Vikuiti™ optical films for further brightness gain.
Vikuiti BEF II:
A second-generation micro-replicated enhancement film. 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 also be translated into power savings.
DBEF – Vikuiti™ Dual Brightness Enhancement Films
A reflective polarizer film, that increases brightness over the entire LCD viewing range.
It can increase on-axis illuminance up to 60% in slab light guide displays and up to 97%
in wedge light guide displays. Vikuiti™ DBEF II is the thinnest multi-layer reflective
polarizer with two diffuse surfaces that provides brightness enhancement for wide viewing angle applications.
