  • Method for stacking surface structured optical films
    Patent number: 6846089
    Abstract: A display includes an optical film that has a surface structure, such as a prismatically structured surface for 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.
    Type: Grant
