  Typical construction of Vikuiti BEFRP film showing theprismatic structure overlaid onto the reflective polarizer (VikuitiDBEF film) substrate, effectively combining the functions oftwo films (Vikuiti DBEF and BEF films) into a single film.  Vikuiti ™ BEFRP 90/24 Film Product configuration  Acrylic resin Vikuiti ™ DBEF Film layer24 µ m90˚ HandHeld devices  vkut ™ Brght ehmt Fm—Rt Porzr (BeFRP) 90/24  a my o prouttht or both ghtg  porztomgmt  g, th fm Tpc Ctct  Vikuiti ™ BEFRP 90/24 Film offers the latest innovation inlight efficiency. It’s the first product to combine the twotechnologies of light angle and polarization management intoa single, thin film. This provides the equivalent brightnessand functionality of two separate prism films. It can alsoimprove the viewing angle. Vikuiti BEFRP 90/24 film deliversmany other benefits such as having to use fewer films in thedisplay and reflective moiré is reduced. Displays can be madethinner; and assembly costs can be cut because only onefilm is handled, rather than two. Vikuiti BEFRP 90/24 film isthinner than two separate films, and so is easier to integrateinto design and manufacturing processes.  For ordering information, please call: 1-800-553-9215 For more information, visit us at: www.vkut.om Important Notice to Purchaser Th oowg  m  u o  wrrt, xpr or mp,ug y mp wrrt o mrhtbty or ft or prtur purpo. 3M warrants that, at the time of shipment, product will meet 3M’s publishedspecification or that specification agreed in writing between 3M and purchaser.Should product not meet specifications at time of shipment, 3M will replace orrefund the purchase price of such quantity of the product found not to meetspecifications.

ToTal sysTem CosT reduCed wiTh VikuiTi BeFrP Film When considering all costs, including procurement,inventorying, administrative, and assembly, VikuitiBEFRP film, in either the “economy” or “performance”configurations, will generally cost less than separatelayers of Vikuiti DBEF and TBEF film, or two layers of Vikuiti TBEF film, and will be significantly thinner withpractically the same or better optical performance. enVironmenTal TesTing  All versions have been tested at low temperature (-40˚Cfor 1000 hours), high temperature (85˚C for 1000 hours),and high humidity/high temperature (65˚C at 95% RH for1000 hours) without any appreciable change in physicalappearance or optical performance.   - F Tf F F   0102030405060708090-100-80-60-40-20020406080100  vikuiti ™  esR + TBeF + TBeF + dBeF-P Film vikuiti ™  esR + TBeF + BeFRP 90/24 Film   F Tf F F Film desCriPTion  Vt ™ BeFrP F The srcinal version for the highest gain in thisfamily of products.  Vt ™ BeFrP2 F Uses improved DBEF substrate for 35 µmthinner version, and better color rendition.
