Title (EN) TRANSMITTANCE VARIABLE DEVICE
(FR) DISPOSITIF À TRANSMITTANCE VARIABLE
(KO) 투과율 가변 장치
Abstract:
(EN) The present application relates to a transmittance variable device and a use thereof. The transmittance variable device of the present application can switch between a transparent state and an opaque state and can exhibit a high transmittance in the transparent state and a high blocking rate in the opaque state while exhibiting an excellent contrast ratio even at an inclined angle. The transmittance variable device of the present application can be applied to various uses that require transmittance adjustment including various architectural or automotive materials, or eyewear such as goggles for an augmented reality experience or sports, sunglasses, or helmets.
(FR) La présente invention concerne un dispositif à transmittance variable et son utilisation. Le dispositif à transmittance variable de la présente invention peut commuter entre un état transparent et un état opaque et peut présenter une transmittance élevée à l'état transparent et un taux de blocage élevé dans l'état opaque tout en présentant un excellent rapport de contraste même à un angle incliné. Le dispositif à transmittance variable de la présente invention peut être appliqué à diverses utilisations qui nécessitent un ajustement de transmittance comprenant divers matériaux architecturaux ou automobiles, ou des lunettes telles que des lunettes pour une expérience de réalité augmentée ou des sports, des lunettes de soleil ou des casques.
(KO) 본 출원은 투과율 가변 장치 및 이의 용도에 관한 것이다. 본 출원의 투과율 가변 장치는 클리어 상태 및 블랙 상태의 사이를 스위칭할 수 있고, 클리어 상태에서의 높은 투과율과 블랙 상태에서의 높은 차단율을 나타내며, 경사각에서도 우수한 콘트라스트비를 나타낼 수 있다. 이러한 본 출원의 투과율 가변 장치는, 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.
