Abstract

The invention provides a liquid lens and a camera module. Two layers of conductive liquid and insulating liquid are filled in a closed cavity to form two interfaces, common electrodes are arranged atthe two ends of the closed cavity respectively, a plurality of driving electrodes are arranged on the peripheral side of the closed cavity respectively, and the driving electrodes are arranged into two groups at intervals in the axial direction of the closed cavity. The curvature of the corresponding interface can be adjusted by adjusting the electric field between each group of driving electrodesand the adjacent common electrode, so that large-range focusing is realized; by adjusting the electric field between one driving electrode and the adjacent common electrode, the curvature of the area, corresponding to the driving electrode, of the adjacent interface can be adjusted, then the electric field between each driving electrode and the adjacent common electrode can be adjusted, and the deflection angle of the optical axis of the adjacent interface can be changed. Therefore, the deflection angle of the optical axis of the liquid lens is adjusted to achieve the anti-shake function.

Description

technical field [0001] The present application belongs to the field of lens technology, and more specifically relates to a liquid lens and a camera module. Background technique [0002] The liquid lens adjusts the curvature of the interface between the two liquids by changing the electric field to change the focal length, thereby achieving focus adjustment. Since the liquid lens can realize the focusing function, the structure of the voice coil motor can be eliminated during use, the structure can be simplified, and the volume of the camera module can be reduced. Therefore, more and more attention is paid to the liquid lens. However, the current liquid lens does not have anti-shake performance. When using it, an additional anti-shake structure is often required, which increases the complexity and size of the lens. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a liquid lens to solve the problems in the related ar...
