Problems solved by technology

[0020] However, conventionally, when the lens driving device and the image sensor board are coupled to each other, it is difficult to handle the flexible circuit board protruding from the lens driving device and connected to the image sensor board, which causes assembly errors of the flexible circuit board and the image sensor board and increases assembly time
[0021] In addition, when the facing portions of the lens driving device and the image sensor board adhered to each other come into contact with each other due to, for example, reliability testing, this may significantly deteriorate the performance of the camera module
[0022] In addition, due to the narrow bonding area of ​​the adhesive provided between the image sensor board and the lens driving device, the lens driving device and the image sensor board may be easily separated from each other due to external impact.

Abstract

One embodiment of the camera module includes: a lens barrel including at least one lens; a bobbin for accommodating the lens barrel; and a fixing part provided between the lens barrel and the bobbin to prevent the lens barrel from contacting the coil. The bobbin is separated, wherein one surface of the bobbin in contact with the surface of the fixing portion may include a bobbin rib provided to protrude toward the lens barrel.

Description

technical field [0001] Embodiments relate to a lens driving device and a camera module including the lens driving device. Background technique [0002] The disclosure described in this section merely provides background information related to the embodiments and does not constitute related art. [0003] Recently, IT products equipped with miniature digital cameras, such as mobile phones, smartphones, tablet computers, and laptop computers, have been actively developed. [0004] In the case of a camera module mounted in a small electronic product such as a smartphone, the camera module may be frequently subjected to shocks during use, and may be slightly shaken due to, for example, a user's hand shake. In view of this, recently, there has been a need to develop a technique in which a hand-shake compensation device is additionally provided to a camera module. [0005] In order to prevent the camera module from slightly shaking due to, for example, user's hand shaking during ...
