technical field

The present disclosure relates to a camera module.

Background technique

Recently, ultra-compact camera modules having high-level functions have been adopted in mobile communication terminals such as tablet personal computers and laptop computers, and mobile phones such as smartphones.

As mobile communication terminals are miniaturized, image quality may be degraded since the influence of hand shake may become noticeable when capturing images. Therefore, in order to obtain clear image quality, a technique for compensating for hand shake is required.

For example, when a hand shake occurs while capturing an image, a lens drive device to which Optical Image Stabilization (OIS) technology is applied can be used to compensate for the hand shake.

The lens driving device applying OIS technology can make the lens module move in the direction perpendicular to the optical axis direction. For this, a suspension wire supporting the lens module and a ball provided between the fixed part and the movable part are used.

However, since the bottom surface of the movable portion is worn by the balls, foreign matter is generated. In addition, since the balls are used, the infrared filter fixed to and mounted on the fixing part may be damaged due to external impact. Furthermore, since the fixing force of the magnets provided on the movable part is small, there is a risk that the magnets will become detached.
