DETAILED DESCRIPTION

[0040] Hereinafter, although examples of the present disclosure will be described in detail with reference to the accompanying drawings, it should be noted that the examples are not limited thereto.

[0041] The following specific embodiments are provided to help the reader gain a comprehensive understanding of the methods, devices, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to the order set forth herein, but may be changed as will be apparent after understanding the present disclosure, except for operations that must occur in a certain order. In addition, descriptions of features known in the art may be omitted for clarity and brevity.

[0042] The features described herein may be implemented in different forms and are not to be construed as being limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent after understanding the present disclosure.

[0043] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, or “coupled to” another element, it may be directly “on”, directly “connected to”, or directly “coupled to” the other element, or one or more other elements may be present between them. Conversely, when an element is described as being “directly” “on”, “directly connected to”, or “directly coupled to” another element, there are no other elements present between them.

[0044] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more of the associated listed items; similarly, "at least one of..." includes any one of the associated listed items and any combination of any two or more of the associated listed items.

[0045] Although terms such as "first", "second", and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Instead, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, the first member, first component, first region, first layer, or first portion mentioned in the examples described herein may also be referred to as the second member, second component, second region, second layer, or second portion without departing from the teachings of the examples.

[0046] For ease of description, spatially relative terms such as "above", "upper", "below", "lower", etc. may be used herein to describe the relationship of one element to another element as shown in the drawings. In addition to the orientation depicted in the drawings, such spatially relative terms are intended to also include different orientations of the device in use or operation. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Therefore, the term "above" includes both the orientation of the above and below, depending on the spatial orientation of the device. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0047] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. The words "a", "an" and "the" are intended to include plural forms as well, unless the context clearly indicates otherwise. The terms "include", "comprises" and "have" specify the presence of stated features, quantities, operations, components, elements and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0048] Due to manufacturing techniques and / or tolerances, the shapes shown in the drawings may vary. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include shape variations that occur during manufacturing.

[0049] Herein, it is noted that the use of the term “may” with respect to an example, such as with respect to what an example may include or implement, means that there is at least one example that includes or implements this feature, and all examples are not limited thereto.

[0050] As will be apparent after understanding the present disclosure, the features of the examples described herein may be combined in various ways. In addition, although the examples described herein have multiple configurations, other configurations are also possible, as will be apparent after understanding the present disclosure.

[0051] Furthermore, throughout the specification, the word “in a plan view” means observing an object from above, and the word “in a cross-sectional view” means observing a section formed by vertically cutting the object from the side.

[0052] Hereinafter, various embodiments and modified examples will be described in detail with reference to the accompanying drawings. The height described below means the distance from the reference point defined in the optical axis direction, and the height needs to be understood to be different from the thickness. The description of the height may mean a relative position based on the optical axis direction (the z-axis direction in the figure). That is, the description "A is higher than B" needs to be understood to mean that A is positioned closer to the light incident direction than the distance of B from the light incident direction.

[0053] Figure 1 is a perspective view showing the appearance of a camera module according to an embodiment, and Figure 2 It is schematically shown Figure 1 An exploded perspective view of the camera module shown in FIG.

[0054] refer to Figure 1 and Figure 2 , a camera module 1000 according to one embodiment may include a lens barrel 100 , a lens driving part 200 , a housing 300 , a cover 400 , a sub housing 500 , and a substrate part 600 .

[0055] The lens barrel 100 may have a hollow cylindrical shape to accommodate a plurality of lenses for capturing an image of an object. The plurality of lenses may be aligned in the optical axis direction (z-axis direction) and mounted in the lens barrel 100. The plurality of lenses may be arranged to determine the state of the required number of lenses according to the design of the lens barrel 100. The individual lenses may have the same or different optical properties (such as refractive index).

[0056] The lens driving part 200 may provide driving power required to operate the lens barrel 100. The lens driving part 200 may include an auto focus (AF) driving part configured to adjust focus, and an optical image stabilization (OIS) driving part configured to correct hand shake or vibration.

[0057] For example, the lens driving part 200 can adjust the focus by moving the lens barrel 100 in the optical axis direction (z-axis direction) using the AF driving part. The lens driving part 200 can correct shaking when capturing an image by moving the lens barrel 100 in a direction perpendicular to the optical axis direction (z-axis direction) using the OIS driving part.

[0058] The housing 300 can accommodate the lens barrel 100 and the lens driving part 200 in its internal space. The housing 300 can have a polyhedral shape having a cross section approximately quadrilateral and a predetermined height. However, the present disclosure is not limited thereto. For example, the housing 300 can have a box shape having openings on the upper side and the lower side.

[0059] The cover 400 may be coupled to the housing 300 to surround the outer surface of the housing 300. The cover 400 may protect internal configuration components in the camera module 1000. In addition, the cover 400 may be used to block electromagnetic waves. For example, the cover 400 may block electromagnetic waves so that electromagnetic waves generated in the camera module 1000 do not affect other electronic components in the electronic device.

[0060] The image sensor module may include an image sensor 700 , a main substrate 610 on which the image sensor 700 is mounted, an optical filter 750 located above the image sensor 700 , and a sub housing 500 on which the optical filter 750 is mounted.

[0061] The substrate portion 600 may transmit an electrical signal generated from the image sensor 700 to a device such as a camera phone. The substrate portion 600 may include a main substrate 610, a connection substrate 630, and a connector 650.

[0062] The main substrate 610 may be electrically connected to the lens driving part 200. The main substrate 610 may be a printed circuit board (PCB) or a flexible printed circuit board (FPCB). The connector 650 may be electrically connected to the main substrate 610. The connector 650 may include a port 651 that may be electrically connected to an external device. The connection substrate 630 may electrically connect the main substrate 610 and the connector 650. The connection substrate 630 may include an FPCB.

[0063] The image sensor 700 may be mounted on the main substrate 610. The image sensor 700 may be electrically connected to the main substrate 610. The image sensor 700 may be positioned below the lens barrel 100 in the optical axis direction (z-axis direction). The image sensor 700 may be positioned in the sub housing 500.

[0064] The filter 750 may be located between the lens barrel 100 and the image sensor 700. The filter 750 may prevent a light beam having a specific frequency band in a light beam passing through the lens from entering the image sensor 700. The filter 750 may include an infrared cutoff filter. The filter 750 may be arranged to be parallel to a direction perpendicular to the optical axis direction (z-axis direction). The filter 750 may be installed in the sub-housing 500.

[0065] When light passes through the lens and the filter 750 and enters the image sensor 700, an image may be formed on the image sensor 700. The image sensor 700 may convert the light emitted to the effective image area into an electrical signal. For example, the image sensor 700 may be, but is not limited to, any one of a charge coupled device (CCD), a metal oxide semiconductor (MOS), a CPD, and a CID.

[0066] In the following, according to this embodiment, reference will be made to Figure 1 , Figure 2 and Figure 3 The sub housing 500 of the camera module 1000 is described in more detail.

[0067] Figure 3 It is shown Figure 2 A perspective view of a sub-housing of a camera module shown in FIG. Figure 4 It is along Figure 3 A cross-sectional view taken along line IV-IV' in FIG. Figure 5 It is along Figure 3 A cross-sectional view taken along line V-V'.

[0068] The sub-housing 500 may be located between the lens barrel 100 and the main substrate 610. The opening portion OP may be located at a central portion of the sub-housing 500. The image sensor 700 may overlap the opening portion OP in the sub-housing 500 in the optical axis direction. The opening portion OP of the sub-housing 500 may have a quadrilateral planar shape.

[0069] The sub-housing 500 may include a mounting area 510 where the optical filter 750 is mounted, and an edge area 530 located around the mounting area 510 .

[0070] The mounting area 510 may include a mounting portion 511 on which the optical filter 750 is mounted, a middle portion 513 extending outward from the mounting portion 511 , and a protruding portion 515 located on an outer side of the middle portion 513 .

[0071] The filter 750 may be seated on the seating portion 511. The seating portion 511 may be formed around the opening portion OP. For example, the opening portion OP may have a quadrangular shape. The seating portion 511 may have a quadrangular frame shape formed around the opening portion OP.

[0072] The filter 750 may be located on the seating portion 511 such that at least a portion of the lower surface of the filter 750 may be seated on the seating portion 511. For example, the filter 750 may have a quadrilateral shape, and an edge of the lower surface of the filter 750 may be seated on the seating portion 511 having a quadrilateral frame shape.

[0073] The middle portion 513 may extend outward from the seating portion 511. For example, the middle portion 513 may extend from all sides of the seating portion 511 having a quadrangular frame shape. That is, at least one middle portion 513 may be located outside each of the four sides of the seating portion 511.

[0074] The middle portion 513 may extend outward from a portion of the seating portion 511. For example, the middle portion 513 may extend from a middle portion of each of the side portions of the seating portion 511 having a quadrangular frame shape.

[0075] Reference Figure 4 and Figure 5 , the height of the middle portion 513c (middle portion 513) may be higher than the height of the mounting portion 511. In addition, the height of the middle portion 513 may be lower than the height of the optical filter 750 mounted on the mounting portion 511. In this case, the height may be determined based on the upper surface or the upper side surface. For example, the height of the middle portion 513 may be less than the height of the upper surface of the optical filter 750 mounted on the mounting portion 511.

[0076] Reference Figure 3 , the middle portion 513 may have a quadrilateral shape. The middle portion 513 may have a tapered structure that becomes higher outward.

[0077] Reference Figure 3 and Figure 4 , the protruding portion 515 may be located outside the middle portion 513. In a plan view, the protruding portion 515 may have a shape that bulges outward. The protruding portion 515 may have a height higher than the middle portion 513. The protruding portion 515 may protrude upward, that is, protrude in the light incident direction. That is, compared to the distance from the middle portion 513 to the lens barrel 100, the protruding portion 515 may be positioned closer to the lens barrel 100 in the optical axis direction. In addition, the height of the protruding portion 515 may be higher than the height of the edge area 530. That is, compared to the distance from the edge area 530 to the lens barrel 100, the protruding portion 515 may be positioned closer to the lens barrel 100 in the optical axis direction (z-axis direction).

[0078] Reference Figures 3 to 5, the protruding portion 515 may be formed only on the outer side of some of the middle portions 513. For example, in the four middle portions 513 respectively extending from the four side portions of the seating portion 511 having a quadrilateral frame shape, the protruding portion 515 may be located outside the edge of a pair of side portions facing each other, and the protruding portion 515 may not be formed outside the edge of the other pair of side portions facing each other. That is, the protruding portion 515 may be formed on the outer side of a pair of middle portions 513a and 513c facing each other, and the protruding portion 515 may not be formed on the outer side of the other pair of middle portions 513b and 513d facing each other.

[0079] The protruding portion 515 may have an arc shape. The protruding portion 515 having an arc shape may overlap with the lens barrel 100 in the optical axis direction. Since the protruding portion 515 overlaps with the lens barrel 100 as described above, the reliability of the portion of the lens barrel 100 can be improved.

[0080] For example, the placement portion 511 may have a quadrilateral frame shape having a pair of long sides (or long side surfaces) and a pair of short sides (or short side surfaces). The protruding portion 515 may be formed on the outside of the middle portions 513a and 513c located outside the long sides, and the protruding portion 515 may not be formed on the outside of the middle portions 513b and 513d located outside the short sides. The maximum height of the protruding portion 515 may be greater than the height of the edge region 530 located outside the edge of the short side.

[0081] The edge region 530 may be located around the mounting region 510 and define the periphery of the sub-housing 500. The edge region 530 may be formed flat. The height of the edge region 530 may be higher than the height of the seating portion 511 and lower than the height of the protruding portion 515.

[0082] The edge region 530 may include a protruding portion 531 protruding outward. The protruding portion 531 may protrude in a direction perpendicular to the optical axis. The protruding portion 531 may be located only on a portion of the edge region 530. For example, the protruding portion 531 may be formed on the outside of the edge of a pair of side portions facing each other among the four side portions of the placement portion 511 having a quadrilateral frame shape. In this case, if the placement portion 511 has a quadrilateral frame shape including a pair of long sides and a pair of short sides, the protruding portion 531 may be located on the outside of the edge of the long side. The protruding portion 531 may have an arc shape.
