METHOD FOR STACKING SURFACE STRUCTURED OPTICAL FILMS

摘要

A display includes an optical film (218) that has a surface structure (222), such as a prismatically structured surface for increasing the brightness of the display. The structured surface is bonded to an opposing surface (228) of a second film (220) using a layer of adhesive (226), 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.
