Description

IRIS MODULE AND CAMERA MODULE INCLUDING THE SAME The present disclosure relates to an aperture module and a camera module including the same. Recently, camera modules have been adopted as standard features in portable electronic devices, including smartphones, tablet PCs, and laptops. As competition for product differentiation in portable electronic devices intensifies, there is an increasing number of cases where the functions of standard digital cameras are applied to the cameras of portable electronic devices. Among these, there is also a growing demand to obtain bokeh effects or bright, clear photos by controlling the amount of light through variable aperture. Conventional digital cameras are equipped with mechanical apertures that operate to vary the amount of light incident according to the shooting environment. However, for camera modules applied to small devices such as portable electronic equipment, it is difficult to apply these mechanical apertures as is due to structural characteristics and spatial limitations. When the aperture module applied to such camera modules is used in large-aperture models, the impact force applied to the aperture magnet holder increases due to the increased weight of the aperture drive unit. Furthermore, when the aperture module is applied to large-aperture models, the overall length of the aperture module increases, thereby extending the distance from the support point of the external force to the point of application, resulting in a larger amount of force generated. Consequently, when an external impact is applied to the aperture module, the deformation and damage of the aperture module and the camera module containing it increase.

Figure 3 is an exploded perspective view of Figure 2. Fig. 4 is a front view of Fig. 2. Fig. 5 is an enlarged side view of the aperture module of Fig. 2.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. The present invention may be embodied in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts unrelated to the explanation have been omitted, and the same reference numerals are used for identical or similar components throughout the specification. In addition, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that all modifications, equivalents, and substitutions included within the concept and technical scope of the present invention are included. Furthermore, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, and thus the present invention is not necessarily limited to what is illustrated. Thicknesses have been enlarged in the drawings to clearly represent various layers and regions. Additionally, for convenience of explanation, the thickness of some layers and regions has been exaggerated in the drawings. Furthermore, when it is said that a part, such as a layer, membrane, region, or plate, is "on" or "on" another part, this includes not only the case where it is "directly above" the other part, but also the case where there is another part in between. Conversely, when it is said that a part is "directly above" another part, it means that there is no other part in between. Also, saying that a part is "on" or "on" a reference part means that it is located above or below the reference part, and does not necessarily mean that it is located "on" or "on" in the direction opposite to gravity. Furthermore, throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Additionally, throughout the specification, "planar" means when the subject part is viewed from above, and "cross-sectional" means when the cross-section obtained by vertically cutting the subject part is viewed from the si
