Title (EN) OPTICAL SHEET STRUCTURE
(FR) STRUCTURE DE FEUILLE OPTIQUE
(KO) 광학시트 구조물
Abstract: front page image
(EN)Disclosed is an optical sheet structure whereby more than a certain level of robustness can be ensured by maintaining the adhesive force between optical sheets while minimising reduction in the optical characteristics of light passing through. The optical sheet structure comprises: a first optical sheet comprising an upper surface in which an optical structure is formed so as to have an area where the upper end part is at different heights; an adhesive layer which is formed on some of the area of the upper surface of the first optical sheet; and a second optical sheet which is disposed on the adhesive layer. The adhesive layer can be formed in the shape of a plurality of dots, in the shape of a plurality of belts or in the shape of a mesh having open areas so as to allow partial adhesion.
(FR)L'invention concerne une structure de feuille optique grâce à laquelle plus d'un certain niveau de robustesse peut être assuré par maintien de la force d'adhérence entre des feuilles optiques tout en réduisant au minimum la réduction des caractéristiques optiques de la lumière passant au travers. La structure de feuille optique comprend: une première feuille optique comprenant une surface supérieure au niveau de laquelle une structure optique est formée de manière à présenter une surface au niveau de laquelle la partie d'extrémité supérieure est à différentes hauteurs; une couche adhésive qui est formée sur une partie de la surface de la surface supérieure de la première feuille optique; et une seconde feuille optique qui est disposée sur la couche adhésive. La couche adhésive peut se présenter sous la forme d'une pluralité de points, sous la forme d'une pluralité de bandes ou sous la forme d'une maille présentant des zones ouvertes de manière à permettre une adhésion partielle.
(KO)통과하는 빛의 광학 특성 저하를 최소화하면서 광학시트간 접착력을 유지하여 일정 수준 이상의 견고함을 확보할 수 있는 광학시트 구조물이 개시된다. 상기 광학시트 구조물은, 상단부의 높이가 상호 상이한 영역을 갖도록 광학 구조가 형성된 상면을 포함하는 제1 광학시트와, 상기 제1 광학시트 상면의 일부 영역에 형성된 접착층 및 상기 접착층 상에 배치되는 제2 광학시트를 포함한다. 상기 접착층은 부분접합이 가능하도록 복수의 도트형상, 복수의 띠형상 또는 오픈 영역을 갖는 매쉬 형상으로 형성될 수 있다.
