Abstract:
(EN) A device and a method for cleaning a camera lens part are provided. The device according to one embodiment of the present invention comprises: a cover glass (substrate); a plurality of electrodes continuously arranged on an upper surface of the cover glass; a dielectric layer stacked on upper surfaces of the electrodes; and a hydrophobic layer stacked on an upper surface of the insulating layer and having droplets formed on the surface thereof, wherein the droplets are moved in the outward direction from the center of the cover glass through a scheme for applying different direct current voltages to a plurality of electrodes among the electrodes.
(FR) L'invention concerne un dispositif et un procédé de nettoyage d'une partie d'objectif d'appareil de prise de vues. Le dispositif selon un mode de réalisation de la présente invention comprend : un verre de recouvrement (substrat) ; une pluralité d'électrodes disposées de manière continue sur une surface supérieure du verre de recouvrement ; une couche diélectrique empilée sur les surfaces supérieures des électrodes ; et une couche hydrophobe empilée sur une surface supérieure de la couche isolante et ayant des gouttelettes formées sur sa surface, les gouttelettes étant déplacées dans la direction vers l'extérieur depuis le centre du verre de recouvrement par le biais d'un processus pour appliquer différentes tensions de courant continu à une pluralité d'électrodes parmi les électrodes.
(KO) 카메라 렌즈부를 클리닝하는 장치 및 방법이 제공된다. 본 발명의 일 실시예에 따른 커버 글래스(Cover Glass;Substrate), 상기 커버 글래스의 상면에 연속으로 배치되는 복수의 전극(Electrode), 상기 전극의 상면에 적층되는 절연 층(Dielectric Layer) 및 상기 절연 층의 상면에 적층되며, 액적(droplet)이 표면에 형성되는 소수성 층(Hydrophobic Layer)을 포함하되, 서로 다른 직류 전압을 상기 전극들 중 복수의 전극들에 인가하는 방식을 통하여 상기 액적이 상기 커버 글래스의 중앙으로부터 외측 방향으로 이동한다.
