Most of them use 3M’s multi-layer technology for this polarized light management in which illumination from the backlight is recycled for greater efficiency and performance. All the films substantially boost display brightness and can be used in conjunction with other Vikuiti products such as Vikuiti Brightness Enhancement Film BEF and Enhanced Specular Reflector ESR . Vikuiti DBEF-E Film This version of Vikuiti DBEF film has an embossed front surface. This embossed surface keeps the film from wetting out or optically coupling to the rear polarizer of liquid crystal panels. Vikuiti DBEF II Film This version of Vikuiti DBEF film has a matte surface on both sides. The matte surface keeps the film from wetting out or optically coupling to the rear polarizer of liquid crystal panels. Vikuiti DBEF-D400 Film This version of Vikuiti DBEF film has outer skins of diffuse polycarbonate. These skins improve the film’s thermal and mechanical properties. Vikuiti DBEF-D550 Film This version of Vikuiti DBEF-D550 film has outer skins of diffuse polycarbonate somewhat thicker than the D400 product. These skins improve the film’s thermal and mechanical properties. 3 Innovation The figures below illustrate the basic construction of the films.

General Converting, Assembly, and Handling Recommendations During converting operations, both the front and rear protective liners should remain on the film. Die cutting is the recommended form of converting and will result in the cleanest edges, although shear cutting and laser cutting may also be acceptable. Whatever method utilized, you should insure that the part has clean, crisp edges without any raggedness or other damage. The part should be precisely cut to provide a close fit in the cavity, yet not so close to experience binding or warping problems from thermal expansion. The part should be left free-floating in the cavity to avoid warping or buckling. If necessary, the part may be tacked down along one edge or two adjacent corners with a double-coated tape, such as Tape # Designs incorporating mounting tabs, or holes mated to mounting pins, are also popular. Remove both protective liners, if the film has them, by tacking near an edge or corner with a piece of aggressive tape and pull gently. If two pieces of 3M Vikuiti Prismatic Film BEF II, BEF III, TBEF are to be incorporated, they should be converted with the grooves of the prism structure of the first sheet at a 90-degree angle to the grooves direction of the second sheet. Be aware that handling any polymer film can generate electrostatic charges, which can attract dust and debris. Remove any loose debris from the film by using compressed air. Avoid fingerprints and debris by wearing clean latex gloves and holding the product at the edges. Keep the area very clean to lessen the likelihood of debris contamination. Maintaining class 1000 clean room conditions is recommended. Using anti-static measures, such as ionized air blowers, whenever possible is recommended. As always, protect the film, especially the edges, from any undue shock or stress. Storage
