Description
CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0019181, filed on Feb. 19, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.


BACKGROUND
Field

The disclosure relates to an electronic device including an electronic component disposed through a display.


Description of Related Art

The development of electronic devices, for example, portable electronic devices, has been applied to various fields that are highly associated with our lives. Such electronic devices are released in various sizes according to their functions and user preferences, and may include a large screen display for securing wide visibility and improving convenience of operation. In addition, even if electronic devices have the same size, technical improvements in which the display area of one electronic device can be relatively expanded than that of the other electronic device are being sought.


An electronic device may include a display that can be visible from the outside through at least a portion of a front plate (e.g., a transparent window, a cover member, or a front cover). In order to meet the needs of a large screen, the area of the display is gradually expanding, whereby the display can be exposed through substantially the entire area of the front plate. In response to this expansion of the display area, various electronic components, the arrangement structure of various electronic components disposed to detect an external environment through the front plate, for example, at least one camera device or various sensors (e.g., an illuminance sensor, an iris sensor, or an infrared ray) may also be transformed. For example, such electronic components may be limited in extending the display area when they are disposed in a black matrix (BM) area other than the display area of the front plate.


In order to expand the display area and to facilitate the arrangement of the electronic components, the display may include openings (e.g., punch holes or perforation holes) formed at positions facing the electronic components. The electronic component is disposed near the rear surface of the front plate in such a manner that the electronic component at least partially penetrates the opening, and functions of the electronic component may be performed. In particular, in the case of a camera device among the electronic components, a barrel is disposed in a state in which at least a portion of the barrel at least partially penetrates the opening of the display, and therefore the display may be hit by the displacement of the barrel according to an external impact of the electronic device. This may cause malfunction of the electronic device.


The above information is presented as background information only to assist with an understanding of the 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 regard to the disclosure.


SUMMARY

Embodiments of the disclosure provides an electronic device that includes an electronic component disposed through a display.


Another embodiment of the disclosure provides an electronic device that includes a display laminated structure in which breakage by an electronic component being displaced by an external impact can be prevented and/or reduced.


In accordance with an example aspect of the disclosure, an electronic device includes: a front plate; a display visible from outside the electronic device through at least a portion of the front plate and disposed in an internal space of the electronic device, the display including a plurality of layers and a first opening; an image sensor disposed in the internal space and configured to be visible through the first opening; and an adhesive layer including a second opening overlapping the first opening between the front plate and the display, the second opening being smaller than the first opening wherein an edge of the first opening is not visible when the display is viewed from above.


In accordance with another example aspect of the disclosure, an electronic device includes: a front plate; a display visible from outside the electronic device through at least a portion of the front plate and disposed in an internal space of the electronic device, the display including a plurality of layers and at least one first opening; at least one electronic component comprising electronic circuitry configured to detect an external environment through the at least one first opening and being disposed in the internal space; and an adhesive layer including at least one second opening overlapping the first opening between the front plate and the display, the second opening being smaller than the first opening wherein an edge of the first opening is not visible when the display is viewed from above.

The housing 110 may refer to a structure that forms a part of the first surface 110A, the second surface 110B, and the lateral surface 110C. The first surface 110A may be formed of a front plate 102 (e.g., a glass plate or polymer plate coated with a variety of coating layers) at least a part of which is substantially transparent. The second surface 110B may be formed of a rear plate 111 which is substantially opaque. The rear plate 111 may be formed of, for example, coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or any combination thereof. The lateral surface 110C may be formed of a lateral bezel structure (or “lateral member”) 118 which is combined with the front plate 102 and the rear plate 111 and includes a metal and/or polymer. The rear plate 111 and the lateral bezel structure 118 may be integrally formed and may be of the same material (e.g., a metallic material such as aluminum).


The front plate 102 may include two first regions 110D disposed at long edges thereof, respectively, and bent and extended seamlessly from the first surface 110A toward the rear plate 111. Similarly, the rear plate 111 may include two second regions 110E disposed at long edges thereof, respectively, and bent and extended seamlessly from the second surface 110B toward the front plate 102. The front plate 102 (or the rear plate 111) may include only one of the first regions 110D (or of the second regions 110E). The first regions 110D or the second regions 110E may be omitted in part. When viewed from a lateral side of the mobile electronic device 100, the lateral bezel structure 118 may have a first thickness (or width) on a lateral side where the first region 110D or the second region 110E is not included, and may have a second thickness, being less than the first thickness, on another lateral side where the first region 110D or the second region 110E is included.

For example, the first opening OP1, the second opening OP2, or the third opening OP3 may be arranged to have a concentric circle when the camera exposure area of the front plate 320 (e.g., the camera exposure area 3211 of FIG. 4) is formed in a circular shape. In this case, it may be arranged to have concentric circles.


According to various embodiments, the camera module 500 (e.g., an image sensor) may include a camera housing 510, a barrel 520 that at least partially protrudes from the camera housing 510, and lens groups 530 disposed in the barrel 520 at regular intervals. According to an embodiment, the camera module 500 may include at least one image sensor member disposed in the internal space of the camera housing 510 to be aligned with the lens groups 320. According to an embodiment, the camera module 500 is disposed such that at least a portion of the barrel 520 contacts or approaches the rear surface 321 of the front plate 320 through the opening OP of the display device 400.


According to various embodiments, the electronic device 300 may include a print area 322 formed on the front plate 320 between the rear surface 321 of the front plate 320 and the adhesive layer 420. According to an embodiment, the print area 322 is formed to have a width that overlaps at least the edge of the opening OP and extends up to at least a portion of the barrel 520 when the front plate 320 is viewed from above. For example, the print area 322 may be formed up to the at least a portion of the barrel 520, but may extend to a position that does not overlap the lens groups 530 to form an angle of view of the camera module 500.


According to various embodiments, the first opening OP1, the second opening OP2, or the third opening OP3 may be formed to have a different distance from the edge of the barrel 520. For example, the second opening OP2 may have a distance d2 between the edge of the second opening OP2 and the edge of the barrel 520 which is shorter than a distance d1 between the edge of the first opening OP1 and the edge of the barrel 520. According to an embodiment, the first opening OP1 may have the distance d1 between the edge of the first opening OP1 and the edge of the barrel 520 which is shorter than a distance d3 between the edge of the third opening OP3 and the edge of the barrel 520. According to an embodiment, when the front plate 320 is viewed from above, the first opening OP1 may be disposed not to be visible by the second opening OP2, and the third opening OP3 may be disposed not to be visible by the first opening OP1. Thus, when the front plate is viewed from above, the first opening OP1, the second opening OP2, or the third opening OP3 may have the same center and shape and have different sizes thereof. For example, the opening OP may be formed to gradually increase in size in order of the second opening OP2, the first opening OP1, and the third opening OP3.


Therefore, when the camera module 500 is randomly displaced by an external impact (e.g., a drop) of the electronic device 300, the barrel 520 may be preferentially brought into contact with the adhesive layer 420, whereby the impact to be transmitted to the display 430 may be preferentially absorbed through the adhesive layer 420.



FIG. 6 is a layout view obtained when the display device 300 is viewed in the rear direction ({circle around (1)} direction) of the front plate 320 from the internal space 3001 of the electronic device 300. The display device 400 may include the support member 440, the display 430 of which the edge is visible through at least a portion of the support member 440, and the adhesive layer 420 of which the edge is visible through at least a portion of the display 430. According to an embodiment, the print area 322 formed on the rear surface 321 of the front plate 320 can be seen through the second opening (e.g., the second opening OP2 of FIG. 5) formed by the adhesive layer 420, and the camera exposure area (e.g., the camera exposure area 3211 of FIG. 4) of the front plate 320 may be determined by the print area 322.



FIG. 7 is a diagram illustrating an arrangement relationship of a camera exposure area 4003 of the example electronic device 300 according to various embodiments of the disclosure.


Referring to FIG. 7, the electronic device 300 may include the display device 400. According to an embodiment, the display device 400 (e.g., display) may include a display area 4001 (e.g., an active area), a BM area 4002 disposed to have a predetermined width along the edge of the display area 4001 (e.g., an inactive area), and the camera exposure area 4003 disposed in the display area 4001. According to an embodiment, the size of the camera exposure area 4003 may be determined through the print area 322 having a predetermined width surrounding a periphery thereof.


According to various embodiments, the camera exposure area 4003 may be determined in the longitudinal direction of the electronic device 300 in consideration of an aspect ratio. For example, the camera exposure area 4003 may consider a distance L1 up to the lower end of the display area 4001 in consideration of an aspect ratio for displaying contents mainly used in the electronic device. For example, when the overall aspect ratio is determined to be 19:9 and the main aspect ratio is 18:9, the camera exposure area 4003 may be disposed between the two aspect ratios in the longitudinal direction of the electronic device. Although not shown, the number of pixels that are not displayed according to the size of the camera exposure area 4003 may be determined. In this case, the display area around the print area 322 may be finely adjusted in size and position, whereby the display area may be an integer multiple of unit pixels, thereby minimizing and/or reducing an area that is not displayed. In another embodiment, a pixel map (e.g., on/off setting) may be adjusted symmetrically in the horizontal and vertical directions, whereby the display area around the print area 322 has a smooth curve shape such as a circle or an ellipse.



FIG. 8 is a cross-sectional view illustrating an arrangement relationship of a camera module 500 of the example electronic device 300 according to various embodiments of the disclosure.


Referring to FIG. 8, a camera exposure area (e.g., the camera exposure area 4003 of FIG. 7) may be determined in size according to the arrangement of peripheral components. For example, the camera exposure area (e.g., the camera exposure area 4003 of FIG. 7) may be determined in size in consideration of a diameter d4 of the barrel 520. For example, when the size of the barrel 520 is reduced due to a reduction of the lens groups 530, the size of the opening (e.g., the opening OP of FIG. 5) of the display device 400 may be reduced and thus, the size of the print area (e.g., the print area 322 of FIG. 7) and the size of the camera exposure area (e.g., the camera exposure area 4003 of FIG. 7) may also be reduced. In another embodiment, by narrowing a gap g between the barrel 520 and the rear surface of the front plate 320, the print area (e.g., the print area 322 of FIG. 7) and camera exposure area (the camera exposure area 4003 of FIG. 7) of the display area (e.g., the display area 4001 of FIG. 7) may be reduced in size while having the same angle of view.


According to various embodiments, a dead space around the camera exposure area (e.g., the camera exposure area 4003 in FIG. 7) may be determined by adhesion tolerances in the display fabrication process, exclusion of permeable bubble areas due to opening formation, and/or an occlusion phenomenon of the active area through the print area. For example, by reducing such a dead space, a distance d5 between the barrel 520 and the display device 400 can be reduced when the print area is determined.


According to various embodiments, when the front plate 320 includes a planar portion 3202 (e.g., a first surface 110A of FIG. 1) and a curved portion 3203 (e.g., e.g., a first area 110D of FIG. 1) extending from the planar portion 3202, the camera exposure area (e.g., the camera exposure area 4003 of FIG. 7) may be disposed in the planar portion 3202. In this case, the camera exposure area (e.g., the camera exposure area 4003 of FIG. 7) may be disposed at a position spaced apart by a predetermined distance d6 in a direction of the planar portion from a point where the curved portion 3203 starts. This separation distance d6 may be determined in consideration of a wiring structure around the camera exposure area and a crack of the display (e.g., the display 430 of FIG. 5) generated when the opening is formed.
