Problems solved by technology

Meanwhile, in a camera device using a liquid lens, when the gap between the lens module and the lens barrel is completely sealed with an adhesive, there are problems as follows: There is no vent for internal air pressure to escape during subsequent curing, so alignment becomes distorted
[0006] In addition, if a vent hole is formed in the actively aligned bond line, the vent hole becomes a passage for foreign matter to enter the image sensor after curing of the actively aligned bond, and thus there is a problem that the vent hole needs to be blocked again
[0008] Furthermore, there is a disadvantage in that additional work for electrically connecting the liquid lens and the conductive structure, such as soldering, is required between the liquid lens and the conductive structure.

Abstract

The present embodiment relates to a camera device comprising: a substrate; an image sensor disposed on the substrate; a base disposed on the substrate; a lens holder disposed on the base; a lens module disposed in the lens holder; a liquid lens module coupled to the lens module; and an adhesive for coupling the lens holder to the base, wherein the lens holder comprises a groove formed between the base and the liquid lens module.

Description

technical field [0001] The present exemplary embodiment relates to a camera device. Background technique [0002] The following description provides background information for the present exemplary embodiments rather than describing the prior art. [0003] With the wide spread and general use of various portable terminals and the commercialization of wireless Internet services, consumers' needs for portable terminals have become diversified, and various types of additional devices are installed in the portable terminals. [0004] Among these additional devices, there are camera devices for photographing objects as photographs or moving pictures. Meanwhile, in recent camera devices, an autofocus function that automatically adjusts the focus according to the distance of the subject is applied. In addition, an image stabilization function is applied, which prevents image shake caused by the photographer's hand shaking. [0005] Recently, the development of a liquid lens that...
