First Claim
Patent Images
1. A method for stacking optical films, comprising:
- pressing prismatic ribs of a prismatically ribbed, first optical film into a first adhesive layer on a surface of a second optical film to a depth so as to leave a gap between portions of the prismatic ribs and the first adhesive layer.

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.

11. A method for stacking optical films, comprising:
pressing active refractive surfaces of refractive features of a first optical film into a first adhesive layer on a surface of a second optical film to a predetermined depth so as to leave a gap between the first adhesive layer and portions of the active refractive surfaces, other portions of the active refractive surfaces contacting adhesive of the first adhesive layer. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
