[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Korean Patent Application No. 10-2018-0095174 filed on August 14, 2018, in the Korean Intellectual Property Office, and Korean Patent Application No. 10-2018-0140774 filed on November 15, 2018, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference in their entirety for all purposes. Technical Field

[0003] The present application relates to a lens assembly and a portable electronic device. Background Art

[0004] In portable electronic devices such as smartphones, camera modules are being used, and recently, there is also a need to reduce the size of camera modules to be mounted in portable electronic devices in accordance with the demand for miniaturization of portable electronic devices.

[0005] However, if the size of the camera module is only reduced, there may be a problem of deterioration in the performance of the camera module. Therefore, research is needed to reduce the size of the camera module while maintaining or improving the performance of the camera module.

[0006] The lens of the camera module is generally circular, and since the image sensor of the camera module has a rectangular shape, light refracted by the lens may not all be imaged on the image sensor.

[0007] Therefore, a method of reducing the size of a camera module by reducing the size of a lens by removing unnecessary portions from the lens may be considered.

[0008] However, in the case where only a portion of the lens is removed, unnecessary light (eg, stray light) may be introduced into a space formed between the lens barrel and the lens, thereby deteriorating the quality of a captured image.

[0009] The above information is presented as background information only to assist with understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with respect to the present disclosure. Summary of the invention

DETAILED DESCRIPTION

[0041] The following detailed description is provided to help the reader obtain a comprehensive understanding of the method, device and / or system described in this application. However, after understanding the disclosure of this application, various changes, modifications and equivalences of the method, device and / or system described in this application will be apparent. For example, the order of operations described in this application is merely an example, and except for the operations that must occur in a specific order, it is not limited to the order set forth in this application, but can make obvious changes after understanding the disclosure of this application. In addition, for greater clarity and brevity, the description of features well known in the art may be omitted.

[0042] The features described in this application may be implemented in different forms and should not be construed as being limited to the examples described in this application. More specifically, the examples described in this application are provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described in this application, which will be apparent after understanding the disclosure of this application. Hereinafter, although embodiments 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.

[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, the element may be directly “on,” “connected to,” or “coupled to” the other element, or one or more other elements may be present between the element and the other element. Conversely, when an element is described as being “directly on,” “directly connected to,” or “directly coupled to” another element, there may be no other elements between the element and the other element.

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

[0045] Although the words such as "first", "second" and "third" may be used in the present application to describe various members, components, regions, layers or parts, these members, components, regions, layers or parts are not limited by these words. More specifically, these words are only used to distinguish one member, component, region, layer or part from another member, component, region, layer or part. Therefore, without departing from the teachings of the examples described in the present application, the first member, first component, first region, first layer or first part mentioned in the example may also be referred to as the second member, second component, second region, second layer or second part, and similarly, the second member, second component, second region, second layer or second part may also be referred to as the first member, first component, first region, first layer or first part.

[0046] Spatially relative terms such as "above", "upper", "under", and "lower" may be used in this application for descriptive convenience to describe the relationship of one element relative to another element as shown in the accompanying drawings. In addition to covering the orientations depicted in the accompanying drawings, these spatially relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the accompanying drawings is flipped, the element described as "above" or "upper" relative to another element will be "under" or "under" relative to the other element. Therefore, depending on the spatial orientation of the device, the term "above" covers both "above" and "under" orientations. The device can also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used in this application should be interpreted accordingly.

[0047] The terms used in this application are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the articles "a", "an" and "the" are intended to also include plural forms. The words "include", "comprise" and "have" indicate the presence of the features, numbers, operations, components, elements and / or combinations thereof, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements and / or combinations thereof.

[0048] Variations in the shapes shown in the drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described in this application are not limited to the specific shapes shown in the drawings but include variations in shapes that occur during manufacturing.

[0049] The features of the examples described in this application can be combined in various ways that will be apparent after understanding the disclosure of this application. In addition, although the examples described in this application have multiple configurations, other configurations that will be apparent after understanding the disclosure of this application are also possible.

[0050] It should be noted that in this application, use of the wording "may" with respect to an example (eg, with respect to what an example may include or implement) means that there is at least one example in which such feature is included or implemented, but all examples are not limited thereto.

[0051] Examples of lens assemblies are described herein, in which the size of the lens assembly can be reduced while ensuring the performance of the lens assembly. The lens assembly according to the examples can be provided in a camera module mounted on a portable electronic device.

[0052] In the examples described herein, the portable electronic device may refer to a portable electronic device such as a mobile communication terminal, a smart phone, a tablet computer, and the like.

[0053] Figure 1 is a perspective view of a lens assembly according to an example, and Figure 2 is a plan view of a lens according to an example.

[0054] Reference Figure 1 and Figure 2 , a lens assembly according to an example includes a lens 100 , a blocking member 200 , and a lens barrel 300 .

[0055] The lens 100 is accommodated in the lens barrel 300. For example, when a plurality of lenses are accommodated in the lens barrel 300, the plurality of lenses are arranged along the optical axis.

[0056] The lens 100 includes an optical portion 110 and a flange portion 130 .

[0057] The optical portion 110 may be a portion presenting optical properties of the lens 100. In an example, light reflected from an object may be refracted while passing through the optical portion 110.

[0058] The optical portion 110 may have positive or negative refractive power, and may have a spherical or aspherical shape.

[0059] The optical part 110 includes an object-side surface OS (eg, a surface facing the object side), and an image-side surface IS (eg, a surface facing the image side). In this example, the object-side surface is convex, and the image-side surface is concave.

[0060] The flange portion 130 may be a portion that fixes the lens 100 to another structure (eg, the lens barrel 300 or another lens).

[0061] The flange portion 130 extends around a portion of the optical portion 110 , and may be integrally formed with the optical portion 110 .

[0062] On the other hand, the lens assembly according to the example may have the characteristics of a telephoto lens, which has a relatively narrow viewing angle. In the example, the viewing angle of the lens assembly may be 40 degrees or less.

[0063] The optical portion 110 and the flange portion 130 are formed to have a non-circular shape. For example, when viewed along the optical axis direction, the optical portion 110 and the flange portion 130 have a non-circular shape (see Figure 2 ).

[0064] The optical portion 110 includes a first edge 111, a second edge 112, a third edge 113, and a fourth edge 114. The first edge 111 and the second edge 112 are positioned opposite to each other, and the third edge 113 and the fourth edge 114 are positioned opposite to each other. The third edge 113 and the fourth edge 114 connect the first edge 111 and the second edge 112 to each other, respectively.

[0065] When viewed in the optical axis direction, the first edge 111 and the second edge 112 include an arc shape, and the third edge 113 and the fourth edge 114 include a substantially linear shape (see Figure 2 ).

[0066] Since the object-side surface OS of the optical portion 110 is convex, the object sides of the third edge 113 and the fourth edge 114 of the optical portion 110 have an arc shape when viewed in a direction perpendicular to the optical axis direction (see FIG. Figure 6 ).

[0067] Reference Figure 2The flange portion 130 includes a first flange portion 131 and a second flange portion 132 . The first flange portion 131 extends from the first edge 111 of the optical portion 110 , and the second flange portion 132 extends from the second edge 112 of the optical portion 110 .

[0068] The first edge 111 of the optical portion 110 may refer to a portion adjacent to the first flange portion 131 , and the second edge 112 of the optical portion 110 may refer to a portion adjacent to the second flange portion 132 .

[0069] The third edge 113 of the optical portion 110 may refer to one side of the optical portion 110 where the flange portion 130 is not formed, and the fourth edge 114 of the optical portion 110 may refer to the other side of the optical portion 110 where the flange portion 130 is not formed.

[0070] The lens 100 is formed of a plastic material and is injection molded by a mold. In this case, the lens 100 according to the example is not formed by cutting a portion of the lens after injection molding, but is formed to have the above-mentioned shape during injection molding.

[0071] Since the lens generally has a substantially circular shape and the image sensor of the camera module has a rectangular shape, light refracted by the circular lens is not entirely imaged on the image sensor.

[0072] Therefore, unnecessary portions are removed from the optical portion of the lens to reduce the size of the lens, thereby reducing the size of the camera module.

[0073] For example, if a portion of the lens is removed after injection molding, the lens may be deformed due to the force applied to the lens during the removal process. In the case where the lens is deformed, the optical performance of the lens is inevitably changed.

[0074] However, in the case of the lens 100 according to the example of the present disclosure, since the optical portion 110 and the flange portion 130 of the lens 100 are formed to have a non-circular shape when performing the injection process, the size of the lens 100 can be reduced and the performance of the lens 100 can also be ensured.

[0075] Figure 3 and 4 is a perspective view of a lens and a blocking member according to an example, Figure 5 is a plan view of a lens and a blocking member according to an example, Figure 6 is a side view of a lens and a blocking member according to an example.

[0076] Figure 7 is a perspective view of a blocking member according to an example, Figure 8 is a first side view of a blocking member according to an example, and Fig. 9 is a second side view of a blocking member according to an example.

[0077] The blocking member 200 is disposed in front of the lens 100 (eg, toward the object side), and is coupled to the lens barrel 300 and / or the lens 100 .

[0078] The blocking member 200 may be provided separately from the lens barrel 300 , or may be formed integrally with the lens barrel 300 .

[0079] The blocking member 200 has a substantially quadrilateral frame shape, and has an opening 210 provided in a central portion thereof so that light may be incident on the lens 100 .

[0080] The blocking member 200 includes a first portion 211, a second portion 212, a third portion 213, and a fourth portion 214. The first portion 211 and the second portion 212 are disposed opposite to each other, and the third portion 213 and the fourth portion 214 are disposed opposite to each other. The third portion 213 and the fourth portion 214 connect the first portion 211 and the second portion 212 to each other, respectively.

[0081] A space surrounded by the first to fourth portions 211 to 214 forms an opening 210. The opening 210 has a non-circular shape similar to that of the optical portion 110.

[0082] The blocking member 200 is in contact with the flange portion 130 , and is not in contact with the optical portion 110 .

[0083] The first portion 211 of the blocking member 200 is disposed at a position corresponding to the first flange portion 131 of the lens 100 , and the second portion 212 of the blocking member 200 is disposed at a position corresponding to the second flange portion 132 of the lens 100 .

[0084] The first portion 211 of the blocking member 200 contacts the first flange portion 131 of the lens 100 , and the second portion 212 of the blocking member 200 contacts the second flange portion 132 of the lens 100 .

[0085] The third portion 213 of the blocking member 200 is disposed at a position where at least a portion thereof corresponds to the third edge 113 of the optical portion 110 of the lens 100 , and the fourth portion 214 of the blocking member 200 is disposed at a position where at least a portion thereof corresponds to the fourth edge 114 of the optical portion 110 of the lens 100 .

[0086] The third portion 213 of the blocking member 200 does not contact the third edge 113 of the optical portion 110 of the lens 100, and the fourth portion 214 of the blocking member 200 does not contact the fourth edge 114 of the optical portion 110 of the lens 100. For example, the third portion 213 of the blocking member 200 may be spaced apart from the third edge 113 of the optical portion 110 of the lens 100, and the fourth portion 214 of the blocking member 200 may be spaced apart from the fourth edge 114 of the optical portion 110 of the lens 100.

[0087] In this example, at least a portion of the third portion 213 of the blocking member 200 is disposed to cover the third edge 113 of the optical portion 110 of the lens 100 in the optical axis direction. At least a portion of the fourth portion 214 of the blocking member 200 is disposed to cover the fourth edge 114 of the optical portion 110 of the lens 100 in the optical axis direction.

[0088] At least a portion of the blocking member 200 facing the optical part 110 in the optical axis direction includes an arc shape.

[0089] Since the object side of the third edge 113 of the optical portion 110 of the lens 100 has an arc shape, the third portion 213 of the blocking member 200 also has an arc shape. For example, the image side of the third portion 213 of the blocking member 200 has an arc shape corresponding to the object side of the third edge 113 of the optical portion 110. On the other hand, the object side of the third portion 213 of the blocking member 200 may also have an arc shape.

[0090] Since the object side of the fourth edge 114 of the optical portion 110 of the lens 100 has an arc shape, the fourth portion 214 of the blocking member 200 also has an arc shape. For example, the image side of the fourth portion 214 of the blocking member 200 has an arc shape corresponding to the object side of the fourth edge 114 of the optical portion 110. On the other hand, the object side of the fourth portion 214 of the blocking member 200 may also have an arc shape.

[0091] At least a portion of the blocking member 200 facing the optical part 110 in the optical axis direction is positioned higher than a portion of the blocking member 200 facing the flange part 130 in the optical axis direction.

[0092] For example, in the optical axis direction, boundaries between the third and fourth edges 113 and 114 of the optical portion 110 and the blocking member 200 are positioned higher than boundaries between the first and second edges 111 and 112 of the optical portion 110 and the blocking member 200 .

[0093] For example, when a virtual straight line L1 (hereinafter, referred to as a first straight line) that passes through the optical axis and connects the lower surface of the first portion 211 and the lower surface of the second portion 212 at the shortest distance is defined as the first straight line, and a virtual straight line L2 (hereinafter, referred to as a second straight line) that passes through the optical axis and connects the lower surface of the third portion 213 and the lower surface of the fourth portion 214 at the shortest distance is defined as the second straight line, the first straight line L1 and the second straight line L2 are located on different planes. For example, the second straight line L2 is located higher than the first straight line L1 in the optical axis direction (see Figure 7 ).

[0094] For example, the positions of the openings 210 formed in the third edge 113 and the fourth edge 114 of the optical portion 110 of the lens 100 are different from the positions of the openings 210 formed in the first edge 111 and the second edge 112 of the optical portion 110 of the lens 100. In this case, the position refers to the position in the optical axis direction.

[0095] The boundary between the optical portion 110 and the flange portion 130 of the lens 100 is formed at substantially the same position along the circumference in the optical axis direction. The boundary between the optical portion 110 and the flange portion 130 is a boundary between the first edge 111 and the first flange portion 131, and / or a boundary between the second edge 112 and the second flange portion 132.

[0096] On the other hand, since the object side of the third edge 113 of the optical portion 110 and the object side of the fourth edge 114 of the optical portion 110 both have an arc shape, the positions of the third edge 113 and the fourth edge 114 in the optical axis direction are not constant.

[0097] Therefore, if the position of the opening 210 formed by the blocking member 200 in the optical axis direction is constant, since a space is inevitably formed between the optical portion 110 of the lens 100 and the blocking member 200, unnecessary light (stray light) is introduced into the space, which adversely affects image quality.

[0098] However, in the case of the lens assembly according to the example of the present disclosure, since the position of the opening 210 formed by the blocking member 200 is formed to correspond to the arc shape of the optical portion 110 of the lens 100, unnecessary light can be prevented from entering the inside of the lens assembly.

[0099] On the other hand, the lens barrel 300 and the lens 100 are configured in such a way that their two surfaces contact each other. For example, the first flange portion 131 and the second flange portion 132 of the lens 100 are configured to contact the inner surface of the lens barrel 300, and the optical portion 110 of the lens 100 is configured not to contact the inner surface of the lens barrel 300.

[0100] For example, the third edge 113 and the fourth edge 114 of the optical portion 110 of the lens 100 are disposed to be spaced apart from the inner surface of the lens barrel 300 in a direction perpendicular to the optical axis.

[0101] Therefore, a predetermined space is formed between the third edge 113 of the optical portion 110 of the lens 100 and the lens barrel 300 , and a predetermined space is also formed between the fourth edge 114 of the optical portion 110 of the lens 100 and the lens barrel 300 .

[0102] Even in the case where the space is formed as described above, with the lens assembly according to the example of the present disclosure, unnecessary light may be prevented from entering the space between the optical portion 110 of the lens 100 and the lens barrel 300 by the blocking member 200 .

[0103] As described above in the examples, the lens assembly according to the examples can reduce the size of the lens assembly while ensuring the performance of the lens assembly.

[0104] Fig.10 1 is a perspective view showing a portable electronic device according to an example. The portable electronic device 1 may include a camera module 10. The camera module 10 may include Figure 1 The lens assembly and the image sensor 30 shown in FIG. 1 include a lens 100 , a blocking member 200 , and a lens barrel 300 .

[0105] The portable electronic device 1 may further include a display unit 20, wherein the camera module 10 is mounted together with the display unit 20 as a front camera of the portable electronic device 1, or is mounted on a side of the portable electronic device 1 other than the side having the display unit 20 as a rear camera. In one example, light incident through the lens 100 may be irradiated on the image sensor 30. The electrical signal converted by the image sensor 30 of the camera module 10 may be output as an image through the display unit 20 of the portable electronic device 1.

[0106] As set forth in the examples described herein, the performance of the lens assembly can be ensured while reducing the size of the lens assembly, thereby also allowing the size of the portable electronic device to be reduced.

[0107] Although specific examples have been shown and described above, it will be apparent after understanding the disclosure of the present application that various changes in form and detail may be made to these examples without departing from the spirit and scope of the claims and their equivalents. The examples described herein are considered to be descriptive only and not for limiting purposes. The description of the features or aspects in each example should be considered to be applicable to similar features or aspects in other examples. Suitable results may also be obtained if the described techniques are performed in a different order, and / or if the components in the described systems, architectures, devices, or circuits are combined in different ways and / or replaced or supplemented by other components or their equivalents. Therefore, the scope of the present disclosure should not be limited by this detailed description, but by the claims and their equivalents, and all variations within the scope of the claims and their equivalents should be understood to be included in the present disclosure.
