Technical Field

The present disclosure relates to an electronic device including a camera module.

Background

With the development of related art, various electronic devices such as mobile electronic devices have been developed and popularized. Recently, such electronic devices tend to have a touch-sensitive display with a large-sized screen, and also have at least one camera module. Typically, such camera modules may be arranged around a display in an electronic device. This is very important for providing both camera functionality and display area.

The above information is provided merely as background information to aid in understanding the present disclosure. There is no determination, nor is there any assertion, as to whether any of the above may be prior art to the present disclosure.

Technical problem

It is desirable to design an electronic device that increases the display area to consume as high a proportion of the limited size of the electronic device as possible while also providing the user with camera functionality. Typically, an electronic device includes a display that is externally viewed through at least a portion of a front panel (e.g., a window or a bezel). In order to meet the demand for a large-sized screen, the display is preferably large-sized so as to be exposed through substantially the entire area of the front plate. In response to the trend of the display area increasing, the arrangement of various electronic components (e.g., at least one camera module) provided through the front panel is also changed accordingly. This is because if the camera module is disposed outside the display region? In a Black Matrix (BM) region of the front plate, the presence of the black matrix reduces the size of the display region.

In order to increase a display area and smoothly arrange electronic components, the front plate may include a camera exposure area (e.g., an opening, a punch hole, or a perforation) formed at a position corresponding to the camera module. Through the camera exposure area, the camera module may receive light from the outside and perform a camera function.

In general, the size of the camera exposure area may be determined according to the outer diameter of the lens barrel of the camera module. The lens barrel is a component of a camera module for receiving and supporting a plurality of lenses. However, the lens barrel may be limited in reducing the overall outer diameter due to the limitation of the structural design for supporting the lens.

According to some embodiments, the lens barrel 420 may be disposed to penetrate the first through hole 301 of the support member 311 and the second through hole 331 of the display 330 and to be close to the lower surface of the front plate 320. According to an embodiment, the plurality of lenses 430 may be supported at their positions by the structural shape of the inner space 4002 of the lens barrel 420. According to an embodiment, among the plurality of lenses 430, the first lens 431 disposed closest to the front plate 320 may be disposed to face a camera exposure area (e.g., the camera exposure area 321 in fig. 3) of the front plate 320 through an opening 4201 formed in the lens barrel 420. According to an embodiment, the size of the camera exposure area 321 of the front plate 320 may be determined depending on the outer diameter of the lens barrel 420 supporting the first lens 431. According to an embodiment, when the camera module 400 (e.g., a Fixed Focus (FF) camera) performs an operation of focusing an image, a relative distance between the lens barrel 420 and the front plate 320 may be fixed. According to an embodiment, when the camera module 400 (e.g., an Auto Focus (AF) camera) performs an operation of focusing an image, a relative distance between the lens barrel 420 and the front plate 320 may vary. For example, the camera module 400 may include a driving motor (e.g., a Voice Coil Motor (VCM), not shown) for moving the lens barrel 420, and the relative distance between the lens barrel 420 and the front plate 320 may be varied by the driving motor.

Accordingly, even if the first lens 431 having the same effective area (e.g., effective diameter or lens portion) is used, since the lens barrel 420 has a relatively small outer diameter, the size of the camera exposure area 321 can be reduced. This may help to increase the size of the display area.

Hereinafter, the structural relationship between the lens barrel 420 and the first lens 431 will be described in detail.

Fig. 5 is an enlarged view illustrating an area B of the camera module 400 illustrated in fig. 4, and fig. 6 is a schematic view illustrating a camera exposure area 321 of the electronic device 100 including the camera module 400 according to some examples of the present disclosure.

The first lens 431 includes a lens portion 4311, a connection portion 4312, and a flange portion 4313. The connection portion 4312 is inclined. For the reasons described above, the flange portion 4313 is lower than the lens portion 4311 and is outward from the lens portion 4311. This makes the diameter D1 of the first lens 431 larger than the diameter of the head portion 421 of the lens barrel that accommodates the lens portion 4311.

In the present disclosure, the term "effective area L1" refers to a portion of the first lens 431 facing the opening 4201 of the lens barrel 420 and receiving a large amount of external light for imaging. In addition, the term "ineffective area L2" refers to another part of the first lens 431 surrounding the effective area L1, which has a structure supported by the lens barrel 420 or engaged with the lens barrel 420 in the inner space 4002 of the lens barrel 420. In addition, the term "first outer diameter D1" refers to the maximum diameter of the first lens 431 including both the effective region L1 and the ineffective region L2. In addition, the term "second outer diameter D2" refers to the outer diameter of head portion 421 of lens barrel 420. In addition, the term "third outer diameter D3" refers to the outer diameter of the main body portion 423 of the lens barrel 420.

Referring to fig. 5 and 6, the camera module 400 may include a first lens 431, the first lens 431 being disposed to be at least partially exposed through an opening 4201 in an inner space 4002 of the lens barrel 420. According to an embodiment, when the front plate 320 is viewed from above, the first lens 431 may include an effective area L1 and an ineffective area L2. The effective area L1 (e.g., effective diameter) may include a lens portion 4311 that overlaps the opening 4201 of the lens barrel 420. The inactive area L2 may include a connection portion 4312 extending from the lens portion 4311 in a direction in which the outer diameter increases, and a flange portion 4313 extending from the connection portion 4312. The connection part 4312 may be engaged with an engagement part 4221 formed in the inner space 4002 of the lens barrel 420.

According to an embodiment, the connection portion 4312 may be formed to extend from the lens portion 4311 in a direction in which the outer diameter increases and to be inclined at an angle (θ). According to an embodiment, the inclination angle (θ) may be in a range of 15 degrees to 75 degrees. According to an embodiment, the first lens 431 may have a first outer diameter D1 including an effective region L1 and an ineffective region L2. According to an embodiment, the connection portion 4312 may be formed to have a uniform, gradually thinner, or gradually thicker thickness. In another embodiment, the connection portion 4312 may be formed such that the inner surface and the outer surface thereof have different inclination angles. According to an embodiment, the flange portion 4313 may be formed to extend outward (i.e., in a direction in which the outer diameter increases) from the connection portion 4312. This allows diameter D1 if first lens 431 is larger than head portion 421 of barrel 420. According to an embodiment, the flange portion 4313 may extend in a direction substantially perpendicular to the stacking direction of the plurality of lenses 430 (i.e., 431, 432, 433, and 434) or in a direction within 5 degrees perpendicular to the stacking direction of the plurality of lenses 430 (i.e., 431, 432, 433, and 434) (here "substantially perpendicular" is understood to be "substantially perpendicular or within 5 degrees perpendicular").

According to some embodiments, the first lens 431 may be disposed in the inner space 4002 of the lens barrel 420 such that the flange portion 4313 contacts and engages with the engagement portion 4221 of the lens barrel 420. Even if the flange portion 4313 is engaged with the engagement portion 4221, other portions of the first lens 431 (i.e., the lens portion 4311 and the connection portion 4312) may not be engaged with the lens barrel 420. This is to achieve accurate alignment of the first lens 431 in the inner space 4002 of the lens barrel 420.

According to some embodiments, lens barrel 420 may include a head portion 421 and a body portion 423. The head portion 421 has an opening 4201, and the opening 4201 is formed to allow the lens portion 4311 of the first lens 431 to be visible from the outside. A body portion 423 extends from the head portion 421. According to an embodiment, the lens portion 4311 of the first lens 431 may be disposed at a position corresponding to the head portion 421 in the inner space 4002 of the lens barrel 420. According to one embodiment, the flange portion 4313 of the first lens 431 may be disposed at a position corresponding to the body portion 423 in the inner space 4002 of the lens barrel 420.

According to some embodiments, the head portion 421 of the lens barrel 420 passes through a first through hole (e.g., the first through hole 301 in fig. 3 and 4) of a support member (e.g., the support member 311 in fig. 3 and 4), and also at least partially passes through a second through hole (e.g., the second through hole 331 in fig. 3 and 4) of a display (e.g., the display 330 in fig. 3 and 4), and is disposed close to the lower surface of the front plate 320. Accordingly, as the outer diameter (e.g., the second outer diameter D2) of the head portion 421 becomes smaller, the size of the camera exposure area 321 (e.g., the print area) formed in the front plate 320 can be reduced. According to an embodiment, in order to reduce the outer diameter of the head section 421 without reducing the size of the effective area L1 of the first lens 431 that receives external light through the opening 4201, the flange portion 4313 of the first lens 431 may be displaced downward toward the body portion 423 of the lens barrel 420 and away from the lens portion 4311 by the connection portion 4312. Accordingly, the head portion 421 may be formed to have a second outer diameter D2 smaller than the first outer diameter D1 of the first lens 431. According to an embodiment, the body portion 423 may be formed to have at least one third outer diameter D3 that is greater than the second outer diameter D2.

According to an embodiment, the third outer diameter D3 of the body portion 423 may be generally greater than the first and second outer diameters D1 and D2. This is because at least a part of the body portion 423 accommodates the flange portion 4313 of the first lens 431 in the inner space 4002 of the lens barrel 420, and because the outer diameter of at least one of the other lenses 432, 433, and 434 sequentially stacked below the first lens 431 may be substantially larger than the outer diameter of the first lens 431.

According to some embodiments, the lens barrel 420 may include a connection surface 422 connecting the head portion 421 and the body portion 423. According to an embodiment, the connection surface 422 may be formed to have a flat surface extending from the bottom of the head portion 421 in a direction substantially perpendicular to the stacking direction of the lenses 430 (i.e., 431, 432, 433, and 434). According to an embodiment, the connection surface 422 may serve as an adhesive surface and/or a receiving surface of a belt member (e.g., a PORON belt having a cushioning property) inserted when the camera module 400 is supported by a support member (e.g., the support member 311 in fig. 4). In another embodiment, a strap member may be interposed between display 330 and connection surface 422.

According to the embodiment, the first lens 431 is disposed in the inner space 4201 of the lens barrel 420 by structural changes of the lens portion 4311 and the flange portion 4313. At this time, a first perpendicular distance H1 from the top of the head portion 421 to an engagement portion 4221 of the lens barrel 420 (with which the flange portion 4313 of the first lens 431 is engaged) may be greater than a second perpendicular distance H2 from the top of the head portion 421 to the connection surface 422.

Fig. 7 is a schematic diagram comparing dimensions of lens barrel 420 'and lens barrel 420, with the lens portion and flange portion of lens barrel 420' arranged consistently (i.e., on the same line), according to some embodiments of the present disclosure.

Referring to fig. 7, even though the size of an opening 4201 formed in the head portion 421 and determining the viewing angle of the camera module 400 is not changed, the outer diameter D2 of the head portion 421 of the lens barrel 420 according to the embodiment of the present disclosure is smaller than the outer diameter D2 'of the head portion 421'. This is because, in the case of the lens barrel 420', the lens portion and the flange portion are arranged in line with each other (i.e., on the same line), and the flange portion 4313 of the first lens 431 is displaced toward the main body portion 423 by the connection portion 4312 and engaged with the lens barrel 420. When the outer diameter D2 of the head part 421 of the lens barrel 420 is reduced, the camera exposure area (e.g., the camera exposure area 321 of fig. 3) (e.g., the print area) formed in the front plate (e.g., the front plate 320 of fig. 3) may also be reduced in size. This may help to increase the size of the display area.

Fig. 8 is a sectional view partially illustrating a lens barrel 420 of a camera module 400 according to some embodiments of the present disclosure.

In fig. 8, the same reference numerals are used to denote the same elements as those of the camera module 400 shown in fig. 5, and redundant description may be omitted.

Referring to fig. 8, in an embodiment of the present disclosure, the first lens 431 may be engaged with the lens barrel 420 in the inner space 4002 of the lens barrel 420 through an inclined structure of the connection part 4314 itself without the above flange part.

According to some embodiments, when the front plate (e.g., the front plate 320 in fig. 4) is viewed from above, the first lens 431 may be composed of an effective region L1 (e.g., an effective diameter) and an ineffective region L2, the effective region L1 including a lens portion 4311 overlapping the opening 4201 of the lens barrel 420, the ineffective region L2 including a connection portion 4314 extending from the lens portion 4311. According to an embodiment, the connection portion 4314 may extend from the lens portion 4311 in a direction in which the outer diameter increases and be inclined toward the body portion 423.

According to some embodiments, the lens barrel 420 may include an inclined surface 4222 formed to face the inner space 4002 and correspond to the connection portion 4314 of the first lens 431. According to an embodiment, once first lens 431 is inserted toward opening 4201 in inner space 4002 of lens barrel 420, first lens 431 may be engaged with lens barrel 420 by contact between the outer surface of connection portion 4314 and inclined surface 4222 of lens barrel 420. In this case, the engagement structure between the first lens 431 and the lens barrel 420 through the connection portion 4314 may be implemented at the body portion 423 instead of the head portion 421. Accordingly, the head part 421 of the lens barrel 420 may be formed to have a second outer diameter D2 that is smaller than the first outer diameter D1 of the first lens 431 and is also reduced compared to the outer diameter D2 'of the head part 421' of fig. 7. This means that when the outer diameter D2 of the head portion 421 of the lens barrel 420 is reduced without changing the size of the opening 4201, the size of the camera exposure area (e.g., the camera exposure area 321 of fig. 3) (e.g., the print area) formed in the front plate (e.g., the front plate 320 of fig. 3) can also be reduced.

According to some embodiments of the present disclosure, an electronic device (e.g., electronic device 300 in fig. 4) may include a housing (e.g., housing 110 of fig. 1) and a camera module (e.g., camera module 400 of fig. 4) disposed in an interior space of the housing. The camera module may include a lens barrel (e.g., lens barrel 420 in fig. 4) having an opening (e.g., opening 4201 in fig. 4), and a plurality of lenses (e.g., lens 430 in fig. 4) disposed to be aligned with the image sensor in an inner space of the lens barrel (e.g., inner space 4002 in fig. 4). Among the plurality of lenses, a first lens (e.g., first lens 431 in fig. 5) disposed closest to the opening and having a first outer diameter (e.g., first outer diameter D1 in fig. 5) may include: a lens portion (e.g., lens portion 4311 in fig. 5) as an effective region (e.g., effective region L1 in fig. 5) provided so as to be exposed to the opening; a connection portion (e.g., connection portion 4312 in fig. 5) that is a part of the ineffective region (e.g., ineffective region L2 in fig. 5) extending from the lens portion in the first direction in which the outer diameter increases and inclined at a predetermined angle (e.g., angle θ in fig. 5); and a flange portion (for example, a flange portion 4313 in fig. 5) as another portion of the ineffective area extending from the connecting portion in a second direction perpendicular to the stacking direction of the plurality of lenses. The lens barrel may include: a head portion (e.g., head portion 421 in fig. 5) containing an opening and having a second outer diameter (e.g., second outer diameter D2 in fig. 5); a body portion (e.g., body portion 423 in fig. 5) that extends from the head portion, accommodates lenses other than the first lens (e.g., lenses 432, 433, and 434 in fig. 4) among the plurality of lenses, and has a third outer diameter (e.g., third outer diameter D3 in fig. 5) that is larger than the second outer diameter; and an engaging portion (e.g., an engaging portion 4221 in fig. 5) formed in the inner space of the lens barrel and engaged with the flange portion. The first outer diameter of the first lens may be larger than the second outer diameter of the head portion.

According to some embodiments, the first lens may be formed such that at least a part of the lens portion is disposed at a position corresponding to the head portion in the inner space of the lens barrel, and such that the flange portion is disposed at a position corresponding to the body portion in the inner space of the lens barrel.

According to some embodiments, the lens barrel may further include a connection surface (e.g., connection surface 422 in fig. 5) of the head portion and the body portion, and the connection surface may be formed in a second direction from the head portion to the body portion.

According to some embodiments, a first vertical distance from the top of the head portion to the engaging portion (e.g., first vertical distance H1 in fig. 5) may be greater than the height of the head portion (e.g., second vertical distance H2 in fig. 5).

According to some embodiments, the connection portion may extend from the lens portion to be inclined at an angle in a range of 15 degrees to 75 degrees with respect to the second direction.

According to some embodiments, the housing may include at least one cover (e.g., the front plate 320 in fig. 4) including a camera exposure area (e.g., the camera exposure area 321 in fig. 3) corresponding to the lens barrel; and the electronic device may further include a display (e.g., the display 330 in fig. 4) disposed in the inner space of the housing to be seen from the outside through at least a portion of the at least one cover.

According to some embodiments, the display may include an at least partially formed through hole (e.g., the second through hole 331 in fig. 4), and the camera module may be disposed such that the head portion at least partially passes through the through hole.

According to some embodiments, the housing may comprise: at least one cover (e.g., the front plate 320 in fig. 4) including a camera exposure area (e.g., the camera exposure area 321 in fig. 3) corresponding to the lens barrel; and a side member (e.g., side member 310 in fig. 4) surrounding a periphery of the at least one cover. The at least one cover may include a front cover (e.g., front plate 320 in fig. 4) and a rear cover (e.g., rear plate 380 in fig. 4) facing in a direction opposite to the front cover. The side member may be disposed to surround a space (e.g., a space 3001 in fig. 4) between the front cover and the rear cover.

According to some embodiments, the side member may include a support member (e.g., the support member 311 in fig. 4) extending at least partially to the space and having a first through hole (e.g., the first through hole 301 in fig. 4) formed at a position corresponding to the head portion, and the camera module may be disposed between the support member and the rear cover.

According to some embodiments of the present disclosure, an electronic device (e.g., electronic device 300 in fig. 4) may include a housing (e.g., housing 110 in fig. 1), a display (e.g., display 330 in fig. 4), and a camera module (e.g., camera module 400 in fig. 4). The housing may include a front cover (e.g., front plate 320 in fig. 4), a rear cover (e.g., rear plate 380 in fig. 4) facing in a direction opposite to the front cover, and a side member (e.g., side member 310 in fig. 4) surrounding a space (e.g., space 3001 in fig. 4) between the front cover and the rear cover and including a support member (e.g., support member 311 in fig. 4) extending at least partially toward the space. The display may be disposed between the front cover and the support member to be seen from the outside through at least a portion of the front cover. The camera module may be disposed between the rear cover and the support member in the space, and may include a lens barrel (e.g., lens barrel 420 in fig. 4) having an opening (e.g., opening 4201 in fig. 4) formed toward the front cover, and a plurality of lenses (e.g., lens 430 in fig. 4) disposed to be aligned with the image sensor in an inner space (e.g., inner space 4002 in fig. 4) of the lens barrel. Among the plurality of lenses, a first lens (e.g., first lens 431 in fig. 5) disposed closest to the opening and having a first outer diameter (e.g., first outer diameter D1 in fig. 5) may include: a lens portion (e.g., lens portion 4311 in fig. 5) as an effective region (e.g., effective region L1 in fig. 5) provided so as to be exposed to the opening; a connection portion (e.g., connection portion 4312 in fig. 5) that is a part of the ineffective region (e.g., ineffective region L2 in fig. 5) extending from the lens portion in the first direction in which the outer diameter increases and inclined at a predetermined angle (e.g., angle θ in fig. 5); and a flange portion (for example, a flange portion 4313 in fig. 5) as another portion of the ineffective area extending from the connecting portion in a second direction perpendicular to the stacking direction of the plurality of lenses. The lens barrel may include: a head portion (e.g., head portion 421 in fig. 5) containing an opening and having a second outer diameter (e.g., second outer diameter D2 in fig. 5); a body portion (e.g., body portion 423 in fig. 5) that extends from the head portion, accommodates lenses other than the first lens (e.g., lenses 432, 433, and 434 in fig. 4) among the plurality of lenses, and has a third outer diameter (e.g., third outer diameter D3 in fig. 5) that is larger than the second outer diameter; and an engaging portion (e.g., an engaging portion 4221 in fig. 5) formed in the inner space of the lens barrel and engaged with the flange portion.
