(KO) 투과도 가변 필름
Abstract: front page image
(EN)The present application relates to a variable transmittance film and a use thereof. A variable transmittance device of the present application can switch between a clear state and a dark state, and can secure excellent bilateral symmetry by reducing the difference between contrast ratios of left and right viewing angles. This variable transmittance film of the present application can be applied for various uses including various architectural or automotive materials for which adjustment of the transmittance is necessary, or eyewear such as goggles for an augmented reality experience or sports, sunglasses or helmets, etc.
(FR)La présente invention concerne un film à transmittance variable et son utilisation. Un dispositif à transmittance variable de la présente invention peut basculer entre un état clair et un état sombre, et peut assurer une excellente symétrie bilatérale par réduction de la différence entre des rapports de contraste d’angles de visualisation gauche et droit. Ce film à transmittance variable de la présente invention peut être appliqué pour différentes utilisations comprenant différents matériaux architecturaux ou automobiles pour lesquelles l'ajustement de la transmittance est nécessaire, ou des lunettes telles qu’un masque pour une expérience de réalité augmentée ou des sports, des lunettes de soleil ou des casques, etc.
(KO)본 출원은 투과율 가변 필름 및 이의 용도에 관한 것이다. 본 출원의 투과율 가변 장치는 클리어 상태 및 다크 상태의 사이를 스위칭할 수 있고, 좌우 시야각에서의 콘트라스트 비의 차이를 감소시킴으로써 우수한 좌우 대칭성을 확보할 수 있다. 이러한 본 출원의 투과율 가변 필름은 투과율의 조절이 필요한 다양한 건축용 또는 차량용 소재나, 증강 현실 체험용 또는 스포츠용 고글, 선글라스 또는 헬멧 등의 아이웨이(eyewear)를 포함하는 다양한 용도에 적용될 수 있다.
