Title
(EN) STRUCTURE OF OPTICAL SHEET FOR BACKLIGHT UNIT
(FR) STRUCTURE DE FEUILLE OPTIQUE DESTINÉE À UNE UNITÉ DE RÉTROÉCLAIRAGE
(KO) 백라이트 유닛을 위한 광학 시트의 구조
Abstract
(EN) Disclosed is a structure of an optical sheet for a backlight unit. The optical sheet for a backlight unit according to the present invention comprises: an upper optical pattern layer on which optical pattern layers having a preset shape are arranged by a predetermined space; and a lower optical pattern layer which is formed beneath the upper optical pattern layer, and on which optical pattern layers having a preset shape are arranged by a predetermined space. The line of the horizontal direction or vertical direction in which the optical patterns of the lower optical pattern layer are arranged by a predetermined space forms a preset tilting angle with respect to the corresponding line of the horizontal direction or vertical direction in which the optical patterns of the upper optical pattern layer are arranged by a predetermined space.
(FR) La présente invention concerne une structure de feuille optique destinée à une unité de rétroéclairage. La feuille optique destinée à une unité de rétroéclairage selon la présente invention comprend : une couche de motif optique supérieure sur laquelle des couches de motif optique de forme prédéfinie sont disposées au sein d'un espace prédéterminé ; et une couche de motif optique inférieure formée en dessous de la couche de motif optique supérieure, et sur laquelle des couches de motif optique de forme prédéfinie sont disposées au sein d'un espace prédéterminé. La ligne de la direction horizontale ou de la direction verticale dans laquelle les motifs optiques de la couche de motif optique inférieure sont disposés au sein d'un espace prédéterminé forment un angle d'inclinaison prédéfini par rapport à la ligne correspondante de la direction horizontale ou de la direction verticale dans laquelle les motifs optiques de la couche de motif optique supérieure sont disposés au sein d'un espace prédéfini.
(KO) 본 발명에 의한 백라이트 유닛을 위한 광학 시트의 구조가 개시된다. 본 발명에 따른 백라이트 유닛을 위한 광학 시트는 상부에 기 설정된 형태의 광학 패턴 일정한 간격으로 배치되도록 형성되는 상부 광학 패턴층; 및 상기 상부 광학 패턴층의 하부에 형성되되, 상부에 기 설정된 형태의 광학 패턴층이 일정한 간격으로 배치되도록 형성되는 하부 광학 패턴층을 포함하되, 상기 상부 광학 패턴층의 광학 패턴이 일정한 간격으로 배열되는 수평 방향 또는 수직 방향의 라인을 기준으로 이에 상응하는 상기 하부 광학 패턴층의 광학 패턴이 일정한 간격으로 배열되는 수평 방향 또는 수직 방향의 라인과 기 설정된 틸팅 각도를 갖도록 형성되는 것을 특징으로 한다.
