(FR) FILM OPTIQUE STRUCTURE PRESENTANT DES STRUCTURES PYRAMIDALES INTERCALEES
Abstract: front page image
(EN)Optical films are disclosed that include a substantially transparent body (35) having a first surface (34) defined by a substrate portion and a structured surface disposed over the substrate portion opposite to the first surface. The structured surface includes a plurality of smaller pyramidal structures (36) and a plurality of larger pyramidal structures (38) interspersed with the plurality of smaller pyramidal structures. Each pyramidal structure has a base including at least two first sides disposed opposite to each other and at least two second sides disposed opposite to each other. Also disclosed are optical display devices including such optical films to increase the illumination intensity.
