Embodiment Construction
[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0036] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0037] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and oth...

The present application belongs to the field of electrowetting technology, and provides a liquid lens and an optical system. By setting the first transparent electrode plate and the second transparent electrode plate oppositely, the first transparent electrode plate includes at least one first conductive region, and the second transparent electrode plate The electrode plate includes at least one second conductive area, and each first conductive area is arranged opposite to a second conductive area to form a pair of conductive areas; the elastic transparent film is arranged between the first transparent electrode plate and the second transparent electrode plate The spacer area makes the elastic transparent film form a first cavity, and fills the first cavity with a transparent conductive liquid; so that when a voltage is applied between at least one pair of conductive regions, the transparent conductive liquid deforms, making the surface of the elastic transparent film Deformation occurs to form a free-form surface or an aspheric surface, and a liquid lens with a free-form surface or aspheric surface can be realized through electrowetting technology, so that the optical system applied to the liquid lens has a simplified structure and clear imaging edges.
Description
technical field [0001] The present application belongs to the technical field of electrowetting (Electrowetting, EW), and in particular relates to a liquid lens and an optical system. Background technique [0002] Electrowetting refers to changing the wettability of the droplet on the insulating substrate by changing the voltage between the droplet and the insulating substrate, that is, changing the contact angle of the droplet on the insulating substrate to cause deformation and displacement of the droplet . Based on the electrowetting effect of liquid droplets, electrowetting technology is widely used in the fields of display, fluid manipulation, lab-on-chip (Lab-On-Chip), micro-zoom lens and printing. [0003] At present, the surface type of liquid lenses based on electrowetting technology can only be spherical. Spherical lenses tend to cause bloated optical system structure and blurred imaging edges. Contents of the invention [0004] The purpose of this application ...
