Description

Lens assembly and electronic device including the same {LENS ASSEMBLY AND ELECTRONIC DEVICE INCLUDING THE SAME}

One embodiment of the present disclosure relates, for example, to a lens assembly and an electronic device including the same.

The development of portable electronic devices is being applied to various fields closely related to daily life. Portable electronic devices are being released in various sizes depending on the function to be implemented and/or the user's preference, and much research is being conducted to implement a large screen to ensure visibility and increase convenience of user operation. For example, in order to implement a large screen, it is advantageous for electronic devices to have as wide a display area exposed to the outside as possible, and for this purpose, members (e.g. bezels) surrounding the display and/or parts arranged overlapping with the display ( It may be important to miniaturize the size or structure (e.g. camera). The smaller the size or structure of the member surrounding the display (e.g., bezel) and/or the part (e.g., camera) arranged overlapping with the display, the smaller the electronic device will be, even if it includes a display of the same size, with a larger screen ( large screen) can be implemented. According to one embodiment, the smaller the size of the lens barrel of the camera module or the camera housing surrounding the camera module is, the easier it will be to implement a large screen on the display.

Recently, the use of selfies using cameras in portable electronic devices is increasing. Accordingly, electronic devices that were previously sufficient for wide-angle (e.g., 90 degrees or less) shooting have recently been required to be capable of ultra-wide-angle (e.g., greater than 90 degrees) shooting, reflecting consumer needs. However, generally speaking, the wider the angle of view, the larger the size of the lens barrel or camera housing surrounding the camera module is. Therefore, the technical challenge of implementing a wide angle of view may have a trade-off relationship with the technical challenge of implementing a large screen. You can.

Although design is in progress to minimize the outer diameter of the camera module (e.g., minimizing the thickness of the lens barrel) in order to minimize the area of the camera exposed to the outside through the front plate (e.g., window) of the electronics, Design may have limitations.

The above information may be provided as background technology for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing can be applied as prior art to the present disclosure.

According to one embodiment, the camera module 200 may have an optical axis (O-I) from the subject (or external object) side (O, object side) to the image side (I, image side). In explaining the configuration of each lens below, for example, the object side may indicate the direction in which the object is located, and the image side may indicate the direction in which the image (I) is formed. The direction in which the image plane is located can be indicated. In addition, the "surface facing the subject" of the lens, for example, refers to the front of the lens in the drawing according to an embodiment of the present disclosure as the surface on the side where the subject O is based on the optical axis O-I. In addition, the “surface facing the image side” refers to the side where the imaging surface is located based on the optical axis (O-I) and can represent the back of the lens in the drawing. Here, the imaging surface may be, for example, a portion where an imaging device or image sensor is placed and an image is formed. According to one embodiment, looking toward the subject (O) along the optical axis (O-I) based on at least one lens among the plurality of lenses included in the camera module 200 is defined as facing in the first direction. Looking toward the image side (I) along the optical axis (O-I) can be defined as facing the second direction. According to one embodiment, when a lens (e.g., the first lens L1) includes a surface facing the subject side O, the surface facing the subject O is said to face the first direction. You can. And when a certain lens (eg, the first lens L1) includes a surface facing the image side (I), the surface facing the image side (I) can be said to face the second direction.

The plurality of lenses 210 may be arranged with the optical axis (O-I) aligned with the image sensor and/or the camera hole 101a. Here, 'the optical axis (O-I) of the plurality of lenses 210, the image sensor, and/or the camera hole 101a is aligned' means the center of the image sensor and/or the camera of the plurality of lenses 210. This may mean that the center of the hole 101a is located on each optical axis (O-I). The optical axis (O-I) alignment can be implemented by performing a vision align operation in the process of assembling the camera module 200 to the electronic device 100. Referring to the drawings of FIG. 6 and below, which will be described later, at least two lenses are shown aligned along the optical axis (O-I). However, this is only an example and does not limit the scope of the present disclosure.

With the plurality of lenses 210 aligned along the optical axis (O-I), the field of view (FOV) of the camera module 200 is the first lens 211 from the subject side (O) among the plurality of lenses 210. ) may be determined by factors such as the diameter D1 of the head portion 221, the diameter D2 of the head portion 221, and/or the diameter D0 of the camera hole 101a. In addition, the factors for determining the angle of view of the camera module 200 are the distance between the first lens 211 and the head 221 from the subject side (O), and/or the first lens 211 from the subject side (O) ) and the distance to the camera hole 101a may further be included.

For example, the electronic device 100 according to the embodiment shown in FIG. 4 is an example of a front camera, with the head portion 221 of the lens barrel 220 spaced apart from the display panel 101 by a predetermined distance. A camera module 200 whose optical axis (O-I) is aligned with the camera hole 101a of the display panel 101 may be disclosed. However, in the electronic device 100 according to the embodiment shown in FIG. 4, it may be difficult to secure a wide angle of view because the distance between the camera hole 101a and the first lens 211 from the subject side (O) is long.

In contrast, the electronic device 100 according to the embodiment shown in FIG. 5 is another example of a front camera, in which the head portion 221 of the lens barrel 220 is connected to the camera hole 101a of the display panel 101. The camera module 200 can be launched with the optical axis (O-I) aligned with the camera hole 101a of the display panel 101 in at least a partially accommodated state. The electronic device 100 according to the embodiment shown in FIG. 5 can position the head portion 221 of the lens barrel 220 inside the camera hole 101a, so that the camera hole 101a and the subject side (O ), the distance between the first lens 211 can be designed closer, making it easy to secure a relatively wide angle of view.

Referring to FIG. 5 , the head portion 221 may be formed to have a predetermined height H1 on one side of the lens barrel 220. The height H1 of the head portion 221 may be set in consideration of factors such as the depth of the camera hole 101a and the distance between the lens barrel 220 and the display panel 101. For example, the height H1 of the head 221 may be designed to be greater than the depth of the camera hole 101a, and the display panel 101 and the lens barrel 220 may be designed to have a predetermined size to prevent them from contacting each other. It may also be designed taking tolerances into account. Alternatively, according to one embodiment, a damper (not shown) may be provided between the camera module 200 and the display panel 101 to prevent impact, and the height H1 of the head portion 221 is determined by this damper. It may be designed by additionally considering the location and/or height.

However, in the embodiment shown in FIGS. 4 and 5, a plurality of lenses 211 are shown. It should be noted that the shape of each lens included in the lenses 210 and the arrangement within the lens barrel 220 may vary depending on the embodiment. For example, in the embodiments of FIGS. 4 and 5, the position of the first lens 211 from the subject side (O) may be set differently as shown, and may be located closer to or further from the camera hole 101a, It should be noted that the relative position of the camera hole 101a may change depending on the auto focusing (AF) operation of the camera module 300 during the operation of the electronic device 100.
