METHOD FOR STACKING SURFACE STRUCTURED OPTICAL FILMS
Application 3016/CHENP/2005 published 2007-07-27, filed 2005-11-16
A display includes an optical film that has a surface structure, such as aprismatically structured surface lor increasing the brightness of the display. The structured surface is bonded to an opposing surface of a second film using a layer of adhesive, by penetrating the structured surface into the adhesive layer to a depth less than a feature height of the structured surface. The bonded film structure provides additional strength to the films and reduces the possibility of film damage during display assembly.
