Kind Code:
A3
Abstract:
In a new packaging method for light management films (216, 218, 220, 222, 224; 414) in displays (400), such as liquid crystal displays, a stack µ of two or more optical films, such as diffuser layers (216, 224), crossed prismatically structured films (218, 220) and reflective polarizers (222), is held together before insertion into the display frame (402). The stack includes at least two of the films that are adhered together using adhesive (230; 416) positioned outside the viewing area of the films. In some embodiments, the adhesive (230; 416) is provided at one or more tabs (418) provided around the periphery of the film stack µ.
