Description

Electronic device including a waterproof structure

[0001] Embodiments of the present disclosure relate to an electronic device including a waterproof structure.

[0002] As the functional gap between manufacturers narrows, electronic devices are becoming increasingly slimmer to satisfy consumer purchasing desires. They are also being developed to increase rigidity, enhance design aspects, and differentiate their functional elements. Electronic devices may include a waterproof structure to block the ingress of external moisture or foreign substances. Such a waterproof structure needs to be designed with at least one of the following in mind: reduction of the black matrix (BM) area of ​​the display, easy maintenance, cost reduction, reduction of assembly steps, or reinforcement of rigidity.

[0003] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.

[0004] The electronic device may include a housing comprising a support member (or extension member) extending into an internal space, and a display supported by the support member and positioned to be visible from the outside. The display may include an extension (COP, chip on plastic) that extends from the display panel and is positioned in a manner that bends toward the back of the display. The display may include a display driver IC (DDI) positioned on the extension. The extension is electrically connected to a flexible printed circuit board (FPCB) comprising a plurality of electrical elements, and the flexible printed circuit board may be electrically connected to a printed circuit board (e.g., main board) of the electronic device.

[0005] The electronic device may include at least one waterproof member (e.g., waterproof tape) disposed between the display and the support member. The at least one waterproof member may provide a waterproof space by including a first waterproof member disposed between the support member and a molding member (e.g., a heat-curing molding member) applied to at least a portion of the extension, a second waterproof member disposed between the back of the display and the support member, and a third waterproof member connecting the first waterproof member and the second waterproof member. The display control circuit and the flexible substrate may be protected from external moisture and / or foreign substances by being accommodated in the waterproof space.

[0006] The first waterproof member and the second waterproof member cannot be integrally formed due to the step difference between the extension and molding member and the back surface of the display. Therefore, the first and second waterproof members can be connected through a liquid third waterproof member (CIPG, cured in place gasket) that is injected through a through hole from the back surface of the support member and cured.

[0007] However, the application of such a third waterproof member causes an increase in assembly labor and manufacturing costs, and the liquid third waterproof member that has entered the back of the display may be visible from the display outside the electronic device due to deformation that occurs during the curing process. In addition, a problem may arise where part of the molding member is torn off by the tape-shaped first waterproof member during the maintenance process of separating the display from the housing.

[0008] Various embodiments of the present disclosure can provide an electronic device including a waterproof structure that can reduce assembly time and manufacturing costs.

[0009] According to various embodiments, an electronic device including a waterproof structure that can help reduce display defects can be provided.

[0010] According to various embodiments, an electronic device including a waterproof structure that can aid in easy maintenance can be provided.

[0011] However, the problems intended to be solved in this disclosure are not limited to those mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.

[0012] According to various embodiments, an electronic device may include a housing comprising a support member and a display disposed to be supported by the support member. The display may include a display panel, an extension extending from the display panel and folded to the back of the display through bending, and a molding member disposed to cover at least a portion of the extension. The molding member may include a first portion disposed on the extension, a second portion extending from one end of the first portion to the back of the display, and a third portion extending from the other end of the first portion to the back of the display, wherein each of the second portion and the third portion includes an inclined surface that gradually decreases as it moves away from the first portion, and the molding member may include a side wall having a specific height extending from the inclined surface to the back of the display.

[0013] An electronic device according to exemplary embodiments of the present disclosure provides a waterproof structure that forms a waterproof space using only a first waterproof liquid member, which covers at least a portion of an extension of a display and includes an inclined surface that gradually decreases as it proceeds toward the end, and a second waterproof member disposed between the back surface of the display and the support member, and a second waterproof member. This allows for a reduction in assembly time and manufacturing costs, helps reduce display defects, and facilitates easy maintenance.

[0014] In addition, various effects that can be identified directly or indirectly through this document may be provided.

In one embodiment, the transparent area may be formed to have a transmittance in the range of about 5% to about 20%. This transparent area may include an area that overlaps with the effective area (e.g., field of view area) of the camera module (205) through which light passes to form an image and generate an image by being formed by an image sensor. For example, the transparent area of ​​the display (400) may include an area with a lower pixel density than the surrounding area. For example, the transparent area may replace the opening. For example, the camera module (205) may include an under-display camera (UDC). In another embodiment, some sensor modules (204) may be positioned to perform their functions without being visually exposed through the front plate (202) within the internal space of the electronic device. For example, in this case, the perforated opening may be unnecessary for the area of ​​the display (400) facing the sensor modules.

[0049] FIG. 3 is an exploded perspective view of the electronic device of FIG. 2 according to various embodiments of the present disclosure.

The interface may, for example, electrically or physically connect the electronic device (200) to an external electronic device and may include a USB connector, an SD card / MMC connector, or an audio connector.

[0054] The battery (243) is a device for supplying power to at least one component of the electronic device (120) and may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell. At least a portion of the battery (243) may be positioned side-by-side so as to be substantially coplanar with, for example, the substrate (240) and / or the sub-substrate (241). The battery (243) may be embedded inside the electronic device (200). In some embodiments, the battery (243) may be detachably positioned from the electronic device (200).

[0055] According to various embodiments, the electronic device (200) may include at least one electrical connection device (245) for electrically connecting a substrate (240) and a sub-substrate (241), and / or a substrate (240) and a module assembly (242). In one embodiment, the at least one electrical connection device (245) may include a flexible printed circuit board (FPCB).

[0056] According to various embodiments, the electronic device (200) may include a waterproof structure comprising at least one waterproof member (481, 482) disposed between the display (400) and the support member (2181). In one embodiment, the electronic device (200) may include a waterproof space (e.g., waterproof space (4801) of FIG. 5a) provided between the display (400) and the support member (2181) through the at least one waterproof member (481, 482). In one embodiment, at least one waterproof member (481, 482) may include a first waterproof member (481) in liquid form that is placed between a molding member (e.g., a molding member (450) in FIG. 5a) that at least partially covers an extension (e.g., an extension (4311) in FIG. 5a) (COP, chip on plastic) of a display (400) and a first surface (2181a) of a support member (2181), and a second waterproof member (482) in the form of a tape that is connected to the first waterproof member (481) and placed between the back surface of the display (400) and the support member (2181). In one embodiment, the molding member (450) may include an inclined surface (e.g., the inclined surface (451) of FIG. 5c) that gradually decreases in thickness as it proceeds toward both ends to overcome the step difference between the molding member (450) and the back surface of the display (400) and to facilitate connecting the first and second waterproof members (481, 482). Accordingly, the first waterproof member (481) can be naturally connected to the second waterproof member (482) by being arranged to extend from the molding member (450) through the inclined surface (451). In one embodiment, the molding member (450) may include a side wall (e.g., the side wall (4511) of FIG. 5d) that extends from the end of the inclined surface (451) and has a specific height from the back surface of the display (400) in order to reduce the phenomenon in which the end of the inclined surface (451) of the molding member (450) peels off together when the display (400) is separated during maintenance.

[0057] An electronic device (200) according to exemplary embodiments of the present disclosure provides a waterproof structure that forms a waterproof space (4801) using only a first waterproof member (481) in liquid form that is applied between a molding member (450) and a support member (2181) and hardens after application, and a second waterproof member (482) disposed between the back surface of the display (400) and the support member (2181), thereby reducing assembly time and manufacturing costs compared to a conventional waterproof structure in which a waterproof space is provided using three or more waterproof members. Furthermore, when the display (400) is coupled to the first surface (2181a) of the support member (2181) and injected through a through hole from the second surface (2181b) and then cured, the existing third waterproof member, such as a CIPG (cured in place gasket) connecting the first and second waterproof members, is deformed during the curing process, causing a display defect visible through the display (400), whereas the first and second waterproof members (481, 482) according to the exemplary embodiment of the present disclosure are both placed between the display (400) and the first surface (2181a) of the support member (2181) and are connected through an inclined surface (4511), so the third waterproof member is not required and can be advantageous for maintenance.

In one embodiment, the conductive sheet (443) may include Cu, Al, Mg, SUS, or CLAD (e.g., a laminated member in which SUS and Al are alternately arranged). In another embodiment, the display (400) may include a detection member (444) (e.g., a digitizer) for detecting input via an electromagnetic induction type electronic pen. In one embodiment, the detection member (444) may be positioned between the polymer member (441) and the functional member (442). In another embodiment, the detection member (444) may be positioned between the display panel (431) and the polymer member (441).In one embodiment, at least one of the auxiliary material layers (440) may be omitted.

[0062] According to various embodiments, the display (400) may include an extension (e.g., a bending part) (4311) that extends from the display panel (431) and is bent toward the back of the display (400).

In some embodiments, the extension (4311) may include a COF (chip on film) structure in which a control circuit (4311a) is mounted on a separate connecting film (not shown) that connects the extension (4311) and a flexible substrate (e.g., the flexible substrate (4312) of FIG. 5a).

[0063] FIG. 5a is a drawing showing the back side of a display according to various embodiments of the present disclosure. FIG. 5b is an enlarged view of area 5b of FIG. 5a according to various embodiments of the present disclosure.

[0064] A display (400) according to exemplary embodiments of the present disclosure may include an unbreakable (UB) type OLED display (e.g., a curved display or a flexible display). However, it is not limited thereto, and the display (400) may include an on-cell touch AMOLED (active matrix organic light-emitting diode) type flat display.

[0065] Referring to FIG. 5a and FIG. 5b, the display (400) may be formed in a rectangular shape. In one embodiment, the display (400) may include a first edge (401) (e.g., a first edge), a second edge (402) (e.g., a second edge) extending perpendicularly from the first edge (401), a third edge (403) (e.g., a third edge) extending from the second edge (402) in a direction parallel to the first edge (401), and a fourth edge (404) (e.g., a fourth edge) extending from the third edge (403) to the first edge (401).

[0066] According to various embodiments, the display (400) may include an extension (4311) that is disposed in a manner that folds from a display panel (e.g., the display panel (431) of FIG. 4) to at least a portion of the back surface (405) of the display (400) at a first edge (401). In one embodiment, the display (400) may include a display control circuit (4311a) disposed in at least a portion of the extension (4311). In one embodiment, the display (400) may include a flexible substrate (4312) that is electrically connected to the extension (4311) and includes a plurality of electrical elements (4312a) and a connector (4312b). In one embodiment, the flexible substrate may be electrically connected to a substrate (e.g., the sub-substrate (240) of FIG. 3) of an electronic device (e.g., the electronic device (200) of FIG. 3) through the connector (4312b). In one embodiment, the display control circuit (4311a) may include a DDI (display driver IC) or TDDI (touch display driver IC) disposed in an extension (4311) having an electrical wiring structure. In one embodiment, the electronic device (e.g., the electronic device (200) of FIG. 3) may include a sensor module (460) disposed on the back (405) of the display (400) and electrically connected (e.g., connected) to a flexible substrate (4312). In one embodiment, the sensor module (460) may include a fingerprint sensor and / or an ultrasonic sensor that detects biometric information of a user who comes into contact with or approaches the surface of the display (400) from outside the electronic device (e.g., the electronic device (200) of FIG. 3). In one embodiment, a plurality of electrical elements (4312a) may include passive elements such as a touch IC, a flash memory for the display, an ESD protection diode, a pressure sensor, a fingerprint sensor, or a decap.In some embodiments, the extension (4311) may extend from any one of the second edge (402), the third edge (403), or the fourth edge (404) of the display.

[0067] According to various embodiments, an electronic device (e.g., the electronic device (200) of FIG. 1) may include a molding member (450) (e.g., a molding member, a protective member, a protective layer, a coating layer, a filling member, or a buffer member) positioned to surround at least an extension (4311) at the first edge (401) of the display (400). In one embodiment, the molding member (450) may be formed by curing a molding liquid of a resin material injected through a molding injector. In one embodiment, the molding member (450) may be formed through a photocurable resin in which the liquid molding liquid is cured by ultraviolet light. In one embodiment, the molding member (450) in which the molding liquid is cured may protect the extension (4311) by having a specified molding modulus value. Additionally, the molding member (450) may be used as an attachment area for a waterproof member (e.g., a first waterproof member (481)). This can help reduce the black matrix (BM) area of ​​the display (400) and enable the realization of a large screen of the display (400) compared to a conventional attachment structure in which a waterproof member is placed between the display (400) and the front cover (202). In one embodiment, the molding member (450) may be positioned to cover at least a portion of the extension (4311) and / or the back (405) of the display (400), excluding the control circuit (4311a). In some embodiments, the molding member (450) may be positioned to cover up to the control circuit (4311a). In one embodiment, the molding member (450) may perform a cushioning function against external impact by having a molding modulus value of about 10 MPa or more.

[0068] According to various embodiments, the molding member (450) may be positioned along the first edge (401) of the display (400). In one embodiment, the molding member (450) may include a first portion (450a) that overlaps with at least an extension (4311) when the face (e.g., back) of the display (400) is viewed from above, a second portion (450b) that extends from one end of the first portion (450a) to a portion of the back surface (405) of the display (400), and a third portion (450c) that extends from the other end of the first portion (450a) to a portion of the back surface (405) of the display (400). In some embodiments, the second portion (405b) may extend to at least a portion of the back surface (405) of the display (400) corresponding to the second edge (402). In some embodiments, the third portion (450c) may extend to at least a portion of the back surface (405) of the display (400) corresponding to the fourth edge (404) of the display (400). In one embodiment, the second portion (450b) and the third portion (450c) may each include an inclined surface (451) that gradually decreases (e.g., gradually decreases in thickness) as it moves away from the first portion (450a).

[0069] According to various embodiments, an electronic device (e.g., the electronic device (200) of FIG. 1) may include at least one waterproof member (481, 482) (e.g., at least one adhesive member). In one embodiment, the at least one waterproof member (481, 482) may include a first waterproof member (481) disposed between a molding member (450) and a support member (e.g., the support member (2181) of FIG. 3) and between the back surface of the display and the support member, and a second waterproof member (482) disposed between the back surface (405) of the display (400) and the support member (2181). In one embodiment, the first waterproof member (481) may be arranged such that one end extends from the first part (450a) through the second part (450b) to the back surface of the display (400), and the other end extends from the first part (450a) through the third part (450c) to the back surface (405) of the display (400). In one embodiment, the first waterproof member (481) may include a bonding member (e.g., bonding liquid) that is cured by natural curing, photocuring (e.g., UV irradiation), or thermal curing after application. In one embodiment, the step difference between the extension portion (4311) and the back surface (405) of the display (400) is formed in the second portion (450b) and the third portion (450c) of the molding member (450), and can be removed through the inclined surface (451) of the molding member (450) formed inclinedly from the outer surface of the molding member (450) corresponding to the first portion (450a) to the back surface (405) of the display (400). Through this inclined structure of the molding member (450), the first waterproof member (481) can be naturally extended from the molding member (450) to the back surface (405) of the display (400) without a peeling section through which moisture and / or foreign substances can enter.

[0070] According to various embodiments, the second waterproof member (482) may be disposed on the back surface (405) of the display (400) corresponding to at least a portion of the second edge (402), at least a portion of the third edge (403), and at least a portion of the fourth edge (404), and both ends may be connected to each end of the first waterproof member (481). In one embodiment, the second waterproof member (482) may be disposed on the back surface (405) of the display (400) corresponding to at least a portion of the first edge (401). In one embodiment, the second waterproof member (482) may include a tape member (e.g., adhesive tape or waterproof tape) attached to the back surface (405) of the display (400).

[0071] According to various embodiments, the second waterproof member (482) may include a first receiving groove (4821) (e.g., a first slit or a first slot) formed at one end and a second receiving groove (4822) (a second slit or a second slot) formed at the other end. In one embodiment, the first receiving groove (4821) and the second receiving groove (4822) may help in close contact between the first waterproof member (481) and the second waterproof member (482) by receiving at least a portion of the first and other ends of the first waterproof member (481). Additionally, the first receiving groove (4821) and the second receiving groove (4822) may help reduce the phenomenon where, when a liquid first waterproof member (481) (e.g., a bonding liquid) is applied, it expands or overflows into an unintended area of ​​the back surface (405) of the display (400) and, after curing, becomes visible through the display (400). In some embodiments, the liquid first waterproof member (481) may be replaced at least partially with waterproof tape.

[0072] According to various embodiments, an electronic device (e.g., the electronic device (200) of FIG. 3) may include a closed-loop waterproof space (4801) provided between the back surface (405) of the display (400) and a support member (e.g., the support member (2181) of FIG. 3) through a first waterproof member (481) and a second waterproof member (482). In one embodiment, the waterproof space (4801) may protect a control circuit (4311a) placed on an extension (4311) and a plurality of electronic elements (4312a) placed on a flexible substrate (4312) from external moisture and / or foreign substances.

[0073] FIG. 5c is an enlarged view of the area 5c of FIG. 5b according to various embodiments of the present disclosure. FIG. 5d is a partial cross-sectional view of a display shown along line 5d-5d of FIG. 5c according to various embodiments of the present disclosure.

[0074] Referring to FIGS. 5c and 5d, the molding member (450) may include a side wall (4511) that extends from the end of the inclined surface (451) and has a specific height (h) from the back surface (405) of the display (400). In one embodiment, if the end of the inclined surface (451) of the molding member (450) is sharply finished on the back surface (405) of the display (400), the end of the molding member (450) may be unintentionally peeled off together with the first waterproof member (481) when the display (400) is separated from the support member (e.g., the support member (2181) of FIG. 3) for maintenance. Thus, the side wall (4511) can help reduce the unintentional peeling of the molding member (450) caused by the separation of the display (400) during maintenance. In one embodiment, the side wall (4511) may be formed substantially perpendicular to the back surface (405) of the display (400). In some embodiments, the side wall (4511) may be formed to be inclined at a specific angle that is not perpendicular to the back surface (405) of the display (400). In one embodiment, the height (h) of the side wall (4511) may be set to at least 0.05 mm. In one embodiment, it is obvious to those skilled in the art that the stepped area formed between the inclined surface (451) of the molding member (450) and the back surface (405) of the display (400) by the side wall (4511) may be filled by the application of a liquid first waterproof member (481). In one embodiment, the side wall (4511) may be defined as a side wall in the direction toward the second edge (402) of the display (400) in the second part (450b). In one embodiment, the height (h) of the side wall (4511) may be defined as the lowest height from the back of the display among the side walls of the second part (450b) including the inclined surface (4511) in the second part (450b). In one embodiment, the side wall of the third part (450c) of the molding member (450) may also be defined in substantially the same way as the second part (450b).For example, the side wall of the third part (450c) can be defined as a side wall facing the fourth edge (404) of the display (400).

[0075] According to various embodiments, the first waterproof member (481) may pass over the inclined surface (451) of the molding member (450) and extend to at least a portion of the back surface (405) of the display (400). Accordingly, the larger the section (S) of the inclined surface (451) through which the first waterproof member passes, the more the design constraints of the first waterproof member (481) (e.g., the non-overlapping structure of the adhesive member (P) and the first waterproof member (481) to be described later in the second part (450b) and the third part (450c)) may be reduced. In this regard, the second part (450b) and / or the third part (450c) may be formed so that the ends narrow to expand the section (S) through which the first waterproof member (481) passes. When the molding liquid is applied to the molding mold (e.g., the upper mold (530) in FIG. 6a) at the narrowed molding end (451a), the molding liquid is not fully injected into the cavity corresponding to the molding end, so a molding defect may occur in which part of the designed molding end (451a) is not formed.

[0076] According to an exemplary embodiment of the present disclosure, a molding mold (e.g., the upper mold (530) of FIG. 6a) comprises an air pocket connected to a cavity for forming a molding end (451a) of a molding member (450), and a molding liquid injected into the molding mold (530) can be injected through the cavity to at least a portion of the air pocket. Through this molding structure, an additional molding portion (452) connected to the molding end (451a) to be actually designed can be formed in the molding member (450), which can reduce the possibility of incomplete molding of the molding end (451a) to be molded. In some embodiments, the additional molding portion (452) formed through the air pocket may be removed.

[0077] FIGS. 6a and 6b are schematic diagrams illustrating a process in which a molding member is applied to a display according to various embodiments of the present disclosure.

[0078] Referring to FIGS. 6a and 6b, the display (400) can be fixed in an aligned manner through a molding jig (510). For example, the first edge (401) of the display (400) can be positioned between the lower mold (520) and the upper mold (530) in the molding jig (510). In one embodiment, the lower mold (520) and the upper mold (530) can be formed from a silicone material. For example, the upper mold (530) may include an inlet (531) for injecting molding liquid and an outlet (532) for discharging over-injected molding liquid. According to one embodiment, the inlet (531) and the outlet (532) can be positioned at the first edge (401) of the display (400) at a location corresponding to both ends of the extension (4311). In one embodiment, when a molding liquid is injected into the injection port (531) of the upper mold (530), the molding liquid fills a space including at least a portion of the extension (4311) of the display (400) and can be cured into a molding member (450) to cover the extension (4311) through photocuring (e.g., UV curing). In some embodiments, the injected molding liquid may be formed into a molding member through natural curing or thermal curing.

[0079] FIG. 7a is a partial perspective view of a display according to various embodiments of the present disclosure. FIG. 7b is a partial drawing of a display illustrating an arrangement structure between a molding first waterproof member and an adhesive member according to various embodiments of the present disclosure. FIG. 7c is a partial cross-sectional view of an electronic device shown along line 7c-7c of FIG. 1 according to various embodiments of the present disclosure.

[0080] In describing the display (400) of FIGS. 7a to 7c, the same reference numerals have been assigned to components identical to those of the display (400) of FIGS. 5a and 5b, and a detailed description thereof may be omitted.

[0081] Referring to FIGS. 7a through 7c, the display (400) may include a display panel (431) attached to the back surface of a front cover (202) via an adhesive member (P) (e.g., OCA, optic clear adhesive). In one embodiment, the adhesive member (P) may be applied to include a protruding portion (P') (e.g., the protruding portion (P') of FIG. 7c) that protrudes outward from the edge of the display panel (431) when the back surface of the display (400) is viewed from above, in order to tightly attach the display panel (431) to the front cover (202) and reduce unintended peeling of the edge (e.g., edge) of the display panel (431). In one embodiment, the first waterproof member (481) may be arranged to overlap with the protruding part (P') of the adhesive member (P) in an area corresponding to the second part (450b) and the third part (450c) where the cushioning effect is relatively reduced, and which includes an inclined surface (451) where the thickness of the molding member (450) gradually decreases when the surface of the display (400) is viewed from above. In one embodiment, the overlapping arrangement structure of the first waterproof member (481) and the protruding part (P') of the adhesive member (P) may cause the protruding part (P') to peel off or deform from the front cover (202) due to stress concentration caused by external impact.

[0082] The first waterproof member (481) according to an exemplary embodiment of the present disclosure may help reduce deformation or peeling of the adhesive member (P) by being positioned so as not to overlap with the protruding portion (P') of the adhesive member (P) protruding outwardly from the display panel (431) at the second portion (450b) and / or third portion (450c) of the molding member (450) when the surface of the display (400) is viewed from above.

[0083] FIG. 8a is a diagram showing the configuration of a molding member according to various embodiments of the present disclosure. FIG. 8b is a partial cross-sectional view of an electronic device shown along line 8b-8b of FIG. 1 in a state where the molding member of FIG. 8a according to various embodiments of the present disclosure is applied.

[0084] Referring to FIGS. 8a and 8b, the electronic device (200) may include a side member (218) and a support member (2181) extending from the side member (218). In one embodiment, the side member (218) and / or the support member (2181) may be formed by combining (e.g., injection molding) a conductive member (218a) (e.g., metal) and a non-conductive member (e.g., polymer). In one embodiment, the electronic device (200) may include a display (400) comprising a molding member (450) positioned to cover at least a portion of the extension (4311). In one embodiment, the display (400) may be positioned to be supported by a first surface (2181a) of the support member (2181). In one embodiment, the electronic device (200) may include a first waterproof member (481) positioned between the molding member (450) and the support member (2181).

[0085] According to various embodiments, excluding the area corresponding to the first waterproof member (481), it may be advantageous for the distance (d) between the first surface (2181a) of the molding member (450) and the support member (2181) to be larger. For example, when an external force is applied to the display (400) due to an external impact such as a fall, the molding member (450) collides with the support member (2181), and this impact is transmitted to the display (400) (particularly, the extension part (4311)), thereby causing damage and / or malfunction of the display (400).

[0086] According to an exemplary embodiment of the present disclosure, the electronic device (400) may have a shock reduction structure (e.g., a first recess (455), a second recess (2181c), or at least one cushioning member (483)) for cushioning external shocks such as the drop of the electronic device (200). In one embodiment, the molding member (450) may include a first recess (455) formed lower than the outer surface of the molding member (4500) in an area corresponding to at least a portion of the first portion (450a). In this case, the first recess (455) may be formed at a position that does not overlap with the first waterproof member (481) when the surface of the display (400) is viewed from above. In one embodiment, the support member (2181) may include a second recess (2181c) formed lower than the first surface (2181a) in an area corresponding to the first recess (455) when the surface of the display (400) is viewed from above. Accordingly, at least a portion of the molding member (450) has a separation distance (d) from the support member (2181) increased by the first recess (455) and the second recess (2181c), thereby preventing mutual impact due to external shock of the electronic device (200). The possibility may be reduced. In some embodiments, the first recess (455) or the second recess (2181c) may be omitted.

[0087] According to various embodiments, the electronic device (200) may include at least one cushioning member (483) disposed between the molding member (450) and the support member (2181). In one embodiment, the at least one cushioning member (483) may be disposed so as not to overlap with the first recess (455) and the first waterproof member (481) when the surface of the display (400) is viewed from above. In one embodiment, the first recess (455) may be located between the first waterproof member (481) and the at least one cushioning member (483) when the surface of the display (400) is viewed from above. In one embodiment, the at least one cushioning member (483) may be disposed in a manner that contacts the first surface (2181a) of the molding member (450) and / or the support member (2181). In one embodiment, the at least one cushioning member (483) may include a sponge or Poron tape.

[0088] FIG. 8c is a partial cross-sectional view of an electronic device shown along line 8b-8b of FIG. 1, with the molding member of FIG. 8a applied according to various embodiments of the present disclosure.

[0089] Referring to FIG. 8c, the electronic device (200) may include an electrical structure (208) (e.g., an IF connector (208)). In one embodiment, the electrical structure (208) may be positioned to overlap at least partially with the molding member (450) when the surface of the display (400) is viewed from above. In this case, the possibility of damage to the display (400) may be increased if an external impact is applied to the electronic device due to the reduced distance between the molding member (450) and the electrical structure (208).

[0090] According to an exemplary embodiment of the present disclosure, the first recess (455) extends into an area corresponding to the electrical structure, thereby increasing the placement efficiency of the electrical structure (208) or inducing an increase in the distance between the electrical structure and the molding member, which can help reduce the possibility of damage to the display (400) due to external impact. For example, a portion of the first recess (455) corresponding to the electrical structure (208) may be located in a portion of the first part (450a) of the molding member (450) (e.g., area 450d in FIG. 8a). In some embodiments, the recess formed in the area corresponding to the electrical structure (208) may include one or more separate recesses separated from the first recess (455). In one embodiment, the electrical structure (208) may include at least one of an interface connector, a socket device, a microphone assembly, or a speaker assembly. In some embodiments, the electrical structure (208) may be replaced with an internal structure of the electronic device (200) (e.g., a bracket, an antenna carrier, or a shield can).

[0091] FIG. 9 is a partial cross-sectional view of an electronic device according to various embodiments of the present disclosure.

[0092] In describing the electronic device (200) of FIG. 9, the same reference numerals have been assigned to components that are substantially identical to those of the electronic device (200) of FIG. 8b, and a detailed description thereof may be omitted.

[0093] Referring to FIG. 9, the molding member (450) may include a recess (456) formed lower than the outer surface of the molding member (450) in an area overlapping with at least one cushioning member (483) when the surface of the display (400) is viewed from above. In one embodiment, at least one cushioning member (483) may be placed on the first surface (2181a) of the support member (2181) so as to have a specific gap (g) with the recess (456). In some embodiments, at least one cushioning member (483) may be attached to the recess (456) and spaced apart from the first surface (2181a) of the support member (2181) so as to have a gap (g). In one embodiment, the spaced structure between the recess (456) and at least one cushioning member (483) may help reduce the possibility of damage to the display (400) due to external impact to the electronic device (200).

[0094] FIG. 10a is a drawing illustrating the arrangement structure of molding members and waterproofing members for providing a waterproof space according to various embodiments of the present disclosure.

[0095] Referring to FIG. 10a, an electronic device (e.g., electronic device (200) of FIG. 3) may include a waterproof space (4901) (e.g., waterproof space (4801) of FIG. 5a) provided through molding members (471, 472) and waterproof members (491, 492, 493, 494) disposed on the back surface (e.g., back surface (405) of FIG. 5a) of a display (e.g., display (400) of FIG. 5a). In one embodiment, the molding members (471, 472) may include a first molding member (471) positioned along a first edge of the display (400) (e.g., the first edge (401) in FIG. 5A) and a second molding member (472) positioned along a third edge of the display (400) (e.g., the third edge (403) in FIG. 5A). In one embodiment, the waterproof members (491, 492, 493, 494) may include at least a first waterproof member (491) disposed on a first molding member (471), a second waterproof member (492) disposed on a second molding member (472), a third waterproof member (493) disposed along a second edge (e.g., the second edge (402) of FIG. 5A) on the back surface (405) of the display (400) and having both ends connected to one end of the first waterproof member (491) and one end of the second waterproof member (492), and a fourth waterproof member (494) disposed along a fourth edge (e.g., the fourth edge (404) of FIG. 5A) on the back surface (405) of the display (400) and having both ends connected to the other end of the first waterproof member (491) and the other end of the second waterproof member (492). In one embodiment, the first waterproof member (491) and the second waterproof member (492) may include a bonding or tape member arranged to extend from the outer surface of each of the first and second molding members (471, 472) to the back surface (405) of the display (400). In one embodiment, the first and second waterproof members (491, 492) may be formed of substantially the same material as the first waterproof member (481) of FIG. 5a.In one embodiment, the third waterproof member (493) and the fourth waterproof member (494) may include a tape member attached to the back surface (405) of the display (400). In one embodiment, the third and fourth waterproof members (493, 494) may be formed of substantially the same material as the second waterproof member (482) of FIG. 5a.
