Problems solved by technology

However, due to the structural configuration of the camera module, it is difficult to completely prevent the intrusion of foreign matter, and it is almost impossible to fundamentally prevent internal foreign matter generated during the execution of the autofocus function from moving toward the IR cut filter, and countermeasures are urgently needed

Abstract

A camera module includes a PCB (Printed Circuit Board) mounted with an image sensor, and a holder member arranged at an upper surface of the PCB and mounted with a plurality of magnets. The camera module also includes a bobbin movably mounted from an inner side of the holder member to a direction of an optical axis and installed at a periphery with a coil unit to enable an electromagnetic interaction with the magnets, and a lug protrusively formed from a floor surface of bobbin to a direction of external diameter of bobbin to overlap with the floor surface of the holder member for a predetermined section.

Description

technical field [0001] Teachings according to example embodiments of the present disclosure generally relate to a camera module. Background technique [0002] In general, the camera module may include an optical system formed with an image sensor, a PCB (Printed Circuit Board) mounted with the image sensor configured to transmit electrical signals, an IR (infrared) cut filter configured to cut light in an infrared region, and At least one lens configured to transmit an image to the image sensor. In this case, the optical system may be mounted with an actuator module configured to perform an auto focus function and a hand shake correction function. [0003] Internal foreign matter generated by the movement of the actuator module and external contaminants such as dust generated during the assembly process may enter the camera module. These foreign substances often fall on the upper surface of the IR cut filter, resulting in poor-quality images, and various measures are being...
