Abstract

A liquid lens module according to an embodiment can comprise: a liquid lens including M (wherein M is a positive integer of 2 or more) individual electrode sectors and N (wherein N is a positive integer of 1 or more) shared electrode sectors; an upper cover including first to M-th individual terminal parts electrically connected to the first to M-th individual electrode sectors, respectively, andexposed in a first direction perpendicular to an optical axis of an image sensor; and a lower cover, which encompasses the liquid lens together with the upper cover and includes first to nth (wherein1 <= n <= N) shared terminal parts electrically connected to the first to Nth shared electrode sectors, respectively, and exposed in the first direction.

Description

technical field [0001] Embodiments relate to a liquid lens module, a lens assembly including the liquid lens module, and a camera module including the lens assembly. Background technique [0002] People who use portable devices require optical devices to be high-resolution, compact, and have various photographing functions. For example, these various photographing functions may be at least one of an optical zoom in / out function, an auto focus (AF) function, or hand shake compensation or an optical image stabilizer (OIS) function. [0003] In the conventional technology, in order to realize the various photographing functions described above, a method of combining a plurality of lenses and directly moving the combined lens is used. However, in the case where the number of lenses increases, the size of the optical device may increase. [0004] Auto focus and hand shake compensation functions are performed by moving or tilting a plurality of lenses fixed to the lens holder an...
