Abstract
The invention is directed to a new packaging method in which several optical films are bundled together before insertion into the display frame. This bundling makes handling of the films easier, reduces the number of steps required for assembly of the display device, reduces the chance of damaging the films and increases yields. At least two of the films in the stack are bonded together using a zero-gap bond. The zero-gap bond lies outside the viewing area of the film.
