Abstract: front page image
(EN)The present invention is a method of forming an optical film (20) including the following steps: providing a first film (22) of a first material (32), extruding a second material (34) to form a second film in a molten state; maintaining the second film in a molten state; bringing the first film (22) proximate the molten second film; patterning the molten second film to form a plurality of structures (24), the structures (24) defining a plurality of cavities (26) therebetween; and solidifying the molten second film.
(FR)L'invention concerne une méthode de formation d'un film optique (20) comprenant les étapes consistant à: fournir un premier film (22) d'un premier matériau (32), extruder un second matériau (34) pour former un second film dans un état fondu; maintenir le second film dans un état fondu; amener le premier film (22) à proximité du second film fondu; créer des motifs sur le second film fondu pour former une pluralité de structures (24), les structures (24) définissant une pluralité de cavités (26) entre ces structures; et faire solidifier le second film fondu.
