    • The present invention relates to a liquid lens which can be focused by an electrical signal and/or fluid pressure. The liquid lens of the present invention comprises: a receptacle which has a cavity with a hemispherical side cross-section, and which receives, in the cavity, an insulating liquid droplet and a conductive liquid droplet which are not mixed with each other and which have the same density; a lower substrate coupled to the lower surface of the receptacle to close the lower surface of the cavity; and an upper substrate coupled to the upper surface of the receptacle to close the upper surface of the cavity, wherein said receptacle includes: an outer wall in which the cavity is formed; a first electrode which is formed at the inner surface of the outer wall, and one end of which is connected to an external power source; a first insulating film which is laminated on the surface of the first electrode, and contacts said conductive liquid droplet and the insulating liquid droplet; and a second electrode which is laminated on a portion of the surface of the first insulating film, and one end of which contacts said conductive liquid droplet and the other end of which is connected to said external power source. The present invention improves the structure of the cavity of the receptacle to achieve efficient focusing using a low driving voltage.
    • 液体透镜本发明涉及一种可以通过电信号和/或流体压力聚焦的液体透镜。 本发明的液体透镜包括:接收器,其具有半球形侧截面的空腔,并且在空腔中接收彼此不混合的绝缘液滴和导电液滴,并且所述接收器具有 密度相同; 耦合到所述容器的所述下表面以闭合所述腔的所述下表面的下基板; 以及耦合到所述容器的上表面以封闭所述腔体的上表面的上基底,其中所述容器包括:外壁,所述腔体形成在所述外壁中; 第一电极,其形成在外壁的内表面,并且其一端连接到外部电源; 第一绝缘膜,其层叠在所述第一电极的表面上,并与所述导电液滴和所述绝缘液滴接触; 以及第二电极,层叠在第一绝缘膜的表面的一部分上,并且其一端接触所述导电液滴并且另一端连接到所述外部电源。 本发明改进了插座的空腔的结构,以使用低驱动电压实现有效聚焦。
