Title (EN) OPTICAL DEVICE DRIVING METHOD
(FR) PROCÉDÉ DE COMMANDE DE DISPOSITIF OPTIQUE
(KO) 광학 소자의 구동 방법
Abstract:
(EN) The present application relates to a method for driving an optical device, the optical device, a transmissivity changing apparatus, and use thereof. One embodiment of the present application may provide a driving method which, even when a cell gap of a GH cell becomes thick, prevents a back flow phenomenon which may be caused by a bulk liquid crystal compound (bulk liquid crystal host), and ensures a fast response speed and an excellent driving characteristic.
(FR) La présente invention concerne un procédé de commande d'un dispositif optique, le dispositif optique, un appareil de changement de transmissivité et leur utilisation. Un mode de réalisation de la présente invention peut fournir un procédé de commande qui, même lorsqu'un espace d'une cellule de type hôte-invité (GH) devient épais, empêche un phénomène de reflux qui peut être provoqué par un composé cristal liquide en masse (hôte à cristaux liquides en masse), et assure une vitesse de réponse rapide et une excellente caractéristique de commande.
(KO) 본 출원은 광학 소자의 구동 방법, 상기 광학 소자, 투과율 가변 장치 및 이의 용도에 관한 것이다. 일 예시에서 본 출원은, GH셀의 셀갭(cell gap)이 두꺼워지는 경우에도 벌크 액정 화합물(Bulk Liquid Crystal Host)에 의한 백플로우(back flow) 현상을 억제하고, 빠른 응답 속도와 우수한 구동 특성이 확보되는 구동 방식이 제공될 수 있다.
