Abstract:
(EN) The present invention relates to a composite optical sheet and a backlight unit comprising the same. According to an embodiment of the present invention, the composite optical sheet comprises: a first base film disposed on a light source; a plurality of first prisms on the first base film; a second base film formed on a plurality of the first prisms; an adhesive layer disposed between a plurality of the first prisms and the second film; a plurality of second prisms on the second base film; a third base film formed on the second prisms; a back coating layer disposed between the second prisms and the third base film; and a plurality of third prisms disposed on the third base film. Therefore, a composite optical sheet having reduced moire and improved coverage can be provided.
(FR) La présente invention concerne une feuille optique composite et une unité de rétroéclairage la comprenant. Selon un mode de réalisation de la présente invention, la feuille optique composite comprend : un premier film de base disposé sur une source lumineuse; une pluralité de premiers prismes sur le premier film de base; un second film de base formé sur une pluralité des premiers prismes; une couche adhésive disposée entre une pluralité des premiers prismes et le second film; une pluralité de seconds prismes sur le second film de base; un troisième film de base formé sur les seconds prismes; une couche de revêtement arrière disposée entre les seconds prismes et le troisième film de base; et une pluralité de troisièmes prismes disposés sur le troisième film de base. On peut ainsi obtenir une feuille optique composite ayant un moiré réduit et un effet couvrant amélioré.
(KO) 본 발명은 복합 광학 시트 및 이를 구비하는 백라이트 유닛에 관한 것이다. 본 발명의 실시예에 따른 복합 광학 시트는, 광원 상에 배치되는 제1 베이스 필름과, 제1 베이스 필름 상의 복수의 제1 프리즘과, 복수의 제1 프리즘 상에 형성되는 제2 베이스 필름과, 복수의 제1 프리즘과 제2 베이스 필름 사이에 배치되는 점착층과, 제2 베이스 필름 상의 복수의 제2 프리즘과, 제2 프리즘 상에 형성되는 제3 베이스 필름과, 제2 프리즘과 제3 베이스 필름 사이에 배치되는 백 코팅층과, 제3 베이스 필름 상에 배치되는 복수의 제3 프리즘을 구비한다. 이에 의해, 모아레 및 은폐력이 개선된 복합 광학 시트를 제공할 수 있게 된다.
