Liquid lens and manufacturing method thereof

Abstract

The invention provides a liquid lens and a manufacturing method thereof. The liquid lens comprises a shell that comprises a first window and a second window; first liquid that is a conductor; second liquid that is an insulator, wherein the first liquid is insoluble in the second liquid; and a substrate connected with the second window, wherein the first liquid and the second liquid are arranged inthe shell, and the second liquid is arranged on the substrate. Through communicating a power source, the shell, the first liquid and the substrate, the first liquid generates an electric wetting effect on touch surfaces with the substrate and the second liquid, the interface curvature between the first liquid and the second liquid is changed, the diopter and focal length of the liquid lens are changed, and thus the effective clear aperture is changed, the miniaturization of the lens module can be achieved, and simultaneous regulation of the focal length and the effective clear aperture of thelens module can be achieved, the application scene is enlarged and the applicability of the application components is improved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a liquid lens and a manufacturing method thereof. Background technique [0002] At present, consumer electronic products such as mobile phones have an optical imaging system. The optical imaging system is mainly a lens module composed of solid lenses. The lens module uses a mechanical motor to adjust the distance between the solid lenses to achieve focusing, which is limited. Due to the size of the mechanical motor and lens module, the lens module has disadvantages such as difficult miniaturization of the imaging system, high power consumption, fixed optical aperture, and crosstalk due to mechanical noise. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a liquid lens and a manufacturing method thereof, which are used to solve the problem of inconvenient miniaturization of the le...
