Abstract

The application provides a liquid lens and a camera module. Two layers of conductive liquid and insulating liquid are filled in the closed cavity to form two interfaces, and the two ends of the closed cavity are respectively provided with common electrodes, and a plurality of driving electrodes are respectively provided on the peripheral sides of the closed cavity. A plurality of driving electrodes are arranged in two groups at intervals along the axial direction of the closed cavity, and the curvature of the corresponding interface can be adjusted respectively by adjusting the electric field between each group of driving electrodes and the adjacent common electrodes, thereby achieving large-scale focusing; and Adjusting the electric field between a driving electrode and the adjacent common electrode can adjust the curvature of the area corresponding to the driving electrode on the adjacent interface, and then can adjust the electric field between each driving electrode and the adjacent common electrode, which can change the light intensity of the adjacent interface. The deflection angle of the optical axis of the liquid lens is further adjusted to realize the anti-shake function.

Description

Liquid lens and camera module technical field

[0001] The application belongs to the technical field of lenses, and more specifically, relates to a liquid lens and a camera module. Background technique The liquid lens is to adjust the curvature of the interface between the two liquids by changing the electric field, to change the focal length, and then realize the Focus now. Since the liquid lens can realize the focusing function, the structure of the voice coil motor can be omitted during use, and the structure can be simplified. Therefore, more and more attention is paid to the liquid lens at present. However, current liquid lenses do not have When using the anti-shake performance, it is often necessary to set an additional anti-shake structure, which increases the complexity and volume of the lens. SUMMARY OF THE INVENTION The purpose of the embodiment of the application is to provide a kind of liquid lens, to solve the liquid lens existing in the related art ...
