Title (EN) OPTICAL FILM HAVING AN ATYPICAL PATTERN, METHOD FOR MANUFACTURING SAME, AND BACKLIGHT ASSEMBLY TO WHICH THE OPTICAL FILM IS APPLIED

Abstract: front page image
(EN)The present invention relates to an optical film having an atypical pattern, to a method for manufacturing same, and to a backlight assembly to which the backlight assembly is applied. The optical film of the present invention comprises: a base layer transmitting light incident from outside; and a pattern layer formed on one or both sides of the base layer, and having a surface structured of a continuously formed polygonal optical pattern having an asymmetrical size and arrangement. Thus, hot-spots and bright lines occurring at a light source and a light incident portion may be prevented. Not only can the pattern density of the optical pattern be maximized to improve brightness, but strong bright points may be effectively scattered and distributed through the atypical pattern to provide the effect of improved shielding ability, thereby contributing to a reduction in the number of expensive optical films used in a backlight assembly and an improvement in brightness values.
(FR)La présente invention concerne un film optique ayant un motif atypique, son procédé de fabrication et un ensemble de rétroéclairage auquel l'ensemble de rétroéclairage est appliqué. Le film optique de la présente invention comprend : une couche de base transmettant une lumière incidente depuis l'extérieur ; une couche de motif formée sur un ou les deux côtés de la couche de base et ayant une surface structurée d'un motif optique polygonal formé de manière continue ayant une dimension et un agencement asymétriques. Ainsi, des taches chaudes et des lignes brillantes se produisant à une source lumineuse et à une partie incidente de lumière peuvent être empêchées. La densité de motif du motif optique peut non seulement être rendue maximale pour améliorer la brillance, mais encore des points brillants forts peuvent être diffusés et distribués de manière efficace à travers le motif atypique pour fournir l'effet d'aptitude à la protection amélioré, contribuant ainsi à une réduction du nombre de films optiques coûteux utilisés dans un ensemble de rétroéclairage et une amélioration de valeurs de brillance.
(KO)본 발명은 비정형 패턴을 갖는 광학필름, 그 제조방법 및 상기 광학필름이 적용된 백라이트 어셈블리에 관한 것으로, 본 발명의 광학필름은 외부로부터 입사되는 광을 투과시키는 기재층과, 상기 기재층의 일면 또는 양면에 형성되며, 크기 또는 배열이 불규칙한 다각형 광학패턴이 연속적으로 형성되어 구조화된 표면을 갖는 패턴층을 포함함으로써, 광원과 입광부에서 발생하는 핫스팟(Hot-spot) 및 휘선을 억제하고, 광학필름의 패턴 밀집도를 최대화하여 휘도를 향상시킬 뿐 아니라, 비정형 패턴을 통해 강한 휘점을 효과적으로 산란 분포시켜 차폐력이 향상되는 효과가 나타나게 되어 결과적으로 백라이트 어셈블리에 사용되는 고가의 광학필름의 개수를 줄이고 휘도값 향상에도 기여할 수 있다.
