Problems solved by technology

However, the lens moving device consumes a lot of power, and requires driving members such as magnets and coils to move the lens module. In addition, in order to move the lens module, an additional space corresponding to the moving range of the lens module needs to be provided, which results in the camera module and the optical device. Increased overall thickness

Embodiment Construction

[0022] Hereinafter, embodiments for achieving the above objects will be described with reference to the accompanying drawings.

[0023] In the following description of the embodiments, it should be understood that when each element is referred to as being "on" or "under" another element, that element may be "directly on" or "under" another element, or may be "indirectly". ” formed such that intervening elements are also present. In addition, when an element is referred to as "on" or "under", meanings of "under the element" and "on the element" may be included based on the element.

[0024] Using electricity to change the surface tension of a liquid is called "electrowetting". When a voltage is applied, the liquid is attracted to the metal plate and becomes flattened, increasing the wetted area. A liquid lens using the electrowetting phenomenon can reduce the size of a camera module compared to a configuration in which the focal length is adjusted by moving the lens, and cons...

Abstract

An embodiment provides a liquid lens comprising: a conductive first plate having a cavity for accommodating a non-conductive first liquid and a conductive second liquid; an electrode arranged on the first plate; a non-conductive second plate arranged on the electrode; a third plate arranged at the bottom part of the first plate; and an insulation layer arranged between the first plate and the electrode, and arranged between the second liquid and the first plate.

Description

technical field [0001] Embodiments relate to a camera module, and more particularly, to a camera module including a liquid lens and an optical device. Background technique [0002] People who use portable devices need high-resolution, compact optical devices with various shooting functions, such as autofocus (AutoFocus, AF) function or hand shake compensation, or optical image stabilization (OIS), which is a shooting function This can be achieved by directly moving the combined multiple shots. However, in the case where the number of lenses increases, the size of the optical device may increase. [0003] The autofocus and hand shake compensation functions can be realized by tilting or moving a lens module including a plurality of lenses, and the lens module is fixed on the lens in a state where the optical axes of the plurality of lenses are aligned along the direction of the optical axis or in the direction perpendicular to the optical axis. on the stand. The lens module...
