Abstract: An optical stack includes an optical film and an optical adhesive disposed on the optical film. The optical adhesive has a major structured surface facing away from the optical film that includes a plurality of channels formed therein. The channels define a plurality of substantially flat land regions therebetween. The land regions include at least about 50% of a total surface area of the major structured surface. When the optical stack is placed on a support surface with the major structured surface of the optical adhesive contacting the support surface, the optical stack bonds to the support surface and may be removed from, or slidingly repositioned on, the support surface without damage to the optical adhesive or the support surface, and upon application of at least one of heat and pressure, the optical stack substantially permanently bonds to the support surface and the plurality of channels substantially disappear.

Abstract: Optical stacks are described. In particular, optical stacks including reflecting-absorbing polarizers and quarter-wave plates are disclosed. The optical core of the optical stack—which includes a reflecting-absorbing polarizer with at least one skin layer including polarizing dye—may be co-extruded or co-stretched.

Abstract: An optical stack includes an optical film (200) and an optical adhesive (500) disposed on the optical film. The optical adhesive has a major structured surface facing away from the optical film that includes a plurality of channels formed therein. The channels define a plurality of substantially flat land regions therebetween. The land regions include at least about 50% of a total surface area of the major structured surface. When the optical stack is placed on a support surface with the major structured surface of the optical adhesive contacting the support surface, the optical stack bonds to the support surface and may be removed from, or slidingly repositioned on, the support surface without damage to the optical adhesive or the support surface, and upon application of at least one of heat and pressure, the optical stack substantially permanently bonds to the support surface and the plurality of channels substantially disappear.

Abstract: The present invention relates to protection films comprising an optical film suitably sized for an illuminated display device, the optical film having perimeter surface portions defining a central region. The protection film further comprises a pressure sensitive adhesive layer at the perimeter surface portions of the optical film. The optical film and/or pressure sensitive adhesive layer has been adapted such that the at least the central region of the optical film contacts the illuminated display device or the central region of the optical film is bonded to the illuminated display device by means of a self-wetting layer. The protection film may be preassembled or may be provided as a kit, the kit comprising an optical film and a double-faced pressure sensitive tape.

Abstract: for receiving an illuminated display device such as a tablet are described. The cases comprise a (e.g. light-collimating) optical film integrated with the case. The illuminated display device is intended to be operated while contained within (rather than being removed from) the case. The illuminated display surface can be viewed through the (e.g. light-collimating) optical film when an illuminated display device is provided within the case.
