Title (EN) VARIABLE TRANSMITTANCE FILM
(FR) FILM À TRANSMITTANCE VARIABLE
(KO) 투과도 가변 필름
Abstract:
(EN) The present application relates to a variable transmittance film and a use thereof, and liquid crystal alignment films comprising splay-aligned liquid crystal molecules are applied to the variable transmittance film of the present application, thereby enabling the pretilt of a liquid crystal interface to be adjusted, and liquid crystal layers or the liquid crystal interface to be vertically and horizontally aligned according to the average tilt angle of the liquid crystal alignment films, thereby ensuring uniformity of operation and quick response speed. In addition, the liquid crystal alignment films are applied to the variable transmittance film of the present application, such that the alignment of liquid crystal molecules are adjusted without using a pretilt control method using an existing rubbing method, thereby enabling the variable transmittance film to be implemented in various modes by a simple coating-drying-hardening method excluding a rubbing step.
(FR) La présente invention concerne un film à transmittance variable et son utilisation, et des films d'alignement de cristaux liquides comprenant des molécules de cristaux liquides à alignement splay sont appliqués au film à transmittance variable de la présente invention, ce qui permet de régler l'inclinaison préalable d'une interface à cristaux liquides, et les couches de cristaux liquides ou l'interface de cristaux liquides sont alignées verticalement et horizontalement en fonction de l'angle d'inclinaison moyen des films d'alignement de cristaux liquides, ce qui permet d'assurer une uniformité de fonctionnement et une vitesse de réponse rapide. De plus, les films d'alignement de cristaux liquides sont appliqués au film à transmittance variable de la présente invention, de telle sorte que l'alignement de molécules de cristaux liquides est ajusté sans utiliser un procédé de commande de pré-inclinaison à l'aide d'un procédé de frottement existant, ce qui permet de mettre en oeuvre le film à transmittance variable dans divers modes par un procédé simple de durcissement-séchage-durcissement excluant une étape de frottement.
(KO) 본 출원은 투과도 가변 필름 및 이의 용도에 관한 것으로, 본 출원의 투과도 가변 필름은 스플레이 배향된 액정 분자를 포함하는 액정 배향막을 적용함으로써 액정 계면의 프리틸트를 조절할 수 있으며, 상기 액정 배향막의 평균 경사각에 따라 액정층 또는 액정 계면의 수직 배향 및 수평 배향이 가능하여, 구동의 균일성 및 빠른 응답 속도를 확보할 수 있다. 또한, 본 출원의 투과도 가변 필름은 액정 배향막을 적용함으로써 기존의 러빙 방식을 이용한 프리틸트 제어 방식이 아닌 액정 분자의 배열을 조절함으로써 러빙 공정을 제외한 단순한 코팅-건조-경화 방법으로 다양한 모드로 구현 가능하다.
