Liquid lens, use method of liquid lens and preparation method of liquid lens

Abstract

The invention provides a liquid lens, a use method of the liquid lens and a preparation method of the liquid lens. The liquid lens at least comprises a substrate layer, a first bendable conductive film layer, a second bendable conductive film layer and a conductive liquid; the substrate layer made of a light-transmitting material; the first bendable conductive film layer is arranged on the surfaceof the substrate layer; a distance is formed between the second bendable conductive film layer and the first bendable conductive film layer; the conductive liquid is located between the first bendable conductive film layer and the second bendable conductive film layer; one of the first bendable conductive film layer and the second bendable conductive film layer is insulated from the conductive liquid, and the other one of the first bendable conductive film layer and the second bendable conductive film layer is electrically connected with the conductive liquid; the first bendable conductive film layer and the second bendable conductive film layer have the advantages of being easy to bend and process, and therefore the zooming range of the liquid lens can be enlarged.

Description

technical field [0001] The invention relates to the field of a liquid lens, in particular to a liquid lens, a method for using the liquid lens and a preparation method thereof. Background technique [0002] With the explosion of science and technology in the information age, people's demand for image collection is also increasing. The lens of the camera is particularly critical to the final image acquisition results. From the initial solid lens with a fixed focal length that cannot be focused, to the use of optical-mechanical structure zooming, the quality of image acquisition has been greatly improved. The optical-mechanical structure zoom method can perform lens zooming, but the optical-mechanical structure zoom lens has problems such as slow zooming speed, large lens size, and limited zoom range. These problems seriously restrict the use of the optical-mechanical structure zoom lens and affect the optical-mechanical structure. The scope of application of the zoom lens. ...
