Embodiment Construction

[0023] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a mobile terminal, an image acquisition module thereof and a liquid lens. The liquid lens comprises a closed cavity, and a first conductive liquid, an insulating liquid and asecond conductive liquid which are filled in the closed cavity, a first optical interface is formed at the boundary of the first conductive liquid and the insulating liquid; a second optical interfaceis formed at the boundary of the second conductive liquid and the insulating liquid; a first electrode and a second electrode are arranged on the outer wall of the closed cavity, the first electrodeis electrically connected with the first conductive liquid and used for adjusting the curvature of the first optical interface when powered on, and the second electrode is electrically connected withthe second conductive liquid and used for adjusting the curvature of the second optical interface when powered on. According to the mobile terminal, the image acquisition module thereof, and the liquid lens, when the voltage of the first electrode and the voltage of the second electrode are changed, the curvature of the first optical interface and the curvature of the second optical interface canbe adjusted respectively without affecting each other, the zoom range is enlarged, and the focusing performance is improved.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, in particular to the mobile terminal and its image acquisition module and liquid lens. Background technique [0002] Shooting is a common function of mobile terminals such as mobile phones and tablet computers. Users have higher and higher requirements for the quality of the captured pictures. However, the current camera zoom range is small and the zoom ratio is not large, which cannot meet the increasingly strong large magnification. Focus needs. Contents of the invention [0003] Embodiments of the present application provide a liquid lens that improves the focusing performance of an image acquisition module, and an image acquisition module and a mobile terminal including the liquid lens. [0004] On the one hand, the present application provides a liquid lens, comprising a closed cavity and a first conductive liquid, an insulating liquid and a second conductive liquid fil...
