exiting from your display. Vikuiti BEF films work by utilizing the principles of refraction and total internal reflection.
The process of refracting usable light towards the viewer and reflecting most of the remaining light back into the
display is called recycling. This form of light management can be done with a single sheet of Vikuiti BEF film or
two sheets crossed at 90 degrees to each other. Vikuiti BEF films can also be used with Vikuiti
Enhancement Films (DBEF) and Vikuiti

for some time. It features an acrylic resin prismatic structure coated on a polyester substrate. This is the highest
performance member of the family, and incorporates structural features which helps avoid wet-out, which is an
optical coupling that can mar the appearance of an LCD display. It is available in the standard 90/50 version, and
a 90/24 version for additional moiré avoidance.
utilizing a randomized prism pattern for increased wet-out and reflective moiré avoidance. It has slightly lower
performance than Vikuiti BEF II film. It is also available in an M (Matte) version. The M version softens the
brightness fall-off at the edges and may allow the elimination of a separate diffuser from the display. Essentially,
Vikuiti BEF III film is a slightly lower cost, slightly lower performance alternative to Vikuiti BEF II film.
half as thick as Vikuiti BEF III film. It is intended for those applications where the thickness of the entire
display/module must be kept to an absolute minimum. Its thin nature makes it somewhat less robust, and should
be restricted to relatively smaller displays where its reduced warp resistance and environmental stability will not
be a factor.
