Figure 1 shows a state before the first member (10) and the second member (20) are fastened, and Figure 2 shows a state after the first member (10) and the second member (20) are fastened.

[0023] Referring to FIGS. 1 and 2, an electronic device according to one embodiment (e.g., electronic device (100) of FIG. 10) may include a first member (10), a second member (20), a fingerprint sensor (50), and an elastic member (30).

[0024] In one embodiment, the first member (10) may include a support portion (13), a first fastening portion (11), and a second fastening portion (12). The support portion (13) may have a substantially plate shape, but is not limited thereto. The support portion (13) may support a fingerprint sensor (50). For example, a support surface (10A) of the support portion (13) may support the fingerprint sensor (50). The support surface (10A) may face the second member (20). The first fastening portion (11) and the second fastening portion (12) may be formed at opposite ends of the support portion (13). For example, the first fastening portion (11) and the second fastening portion (12) may extend from opposite ends of the support portion (13) toward the second member (20), respectively. A fingerprint sensor (50) may be positioned between the first fastening portion (11) and the second fastening portion (12). The first fastening portion (11) and the second fastening portion (12) may be detachably coupled to the second member (20). In one embodiment, the first member (10) may be formed of, but is not limited to, metal and / or plastic. For example, the first member (10) may be formed of a material having rigidity that allows mechanical assembly. For example, the first member (10) may be formed of, but is not limited to, rubber or silicone.

[0025] In one embodiment, the second member (20) may include a first side (20A), a second side (20B), a first fastening portion (21), and a second fastening portion (22). The first side (20A) of the second member (20) may partially form an exterior of the electronic device (e.g., the first side (100A) or the third side (100C) of FIG. 10). The second side (20B) of the second member (20) may be opposite the first side (20A). The second side (20B) may face the second side (50B) of the fingerprint sensor (50). The first side (20A) and the second side (20B) of the second member (20) may be referred to as the third side and the fourth side, respectively.

[0026] In one embodiment, the first fastening portion (21) and the second fastening portion (22) may be formed on the second surface (20B) of the second member (20). The first fastening portion (21) and the second fastening portion (22) may be detachably coupled to the first member (10). In one embodiment, an empty space (40) around the fingerprint sensor (50) may be formed between the first member (10) and the second member (20).

[0027] In one embodiment, the second member (20) may be detachably coupled to the first member (10). For example, the first member (10) and the second member (20) may be coupled via first fastening portions (11, 21) and second fastening portions (12, 22) that are detachably coupled to each other. The first fastening portions (11, 21) and the second fastening portions (12, 22) may include, for example, hooks that are snap-fit ​​coupled. However, the present invention is not limited thereto, and the first fastening portions (11, 21) and the second fastening portions (12, 22) may include various fastening structures that are detachably coupled to each other. For example, the first fastening parts (11, 21) and the second fastening parts (12, 22) may be configured to enable screw fastening, such as the first fastening parts (11-1, 21-1) and the second fastening parts (12-1, 22-1) of FIG. 4.

[0028] In one embodiment, the second member (20) may be formed of, but is not limited to, metal and / or plastic. For example, the second member (20) may be configured to have rigidity that allows mechanical assembly and to allow ultrasonic waves to pass through. For example, the second member (20) may be configured as a part of a housing of the electronic device (e.g., the housing (110) of FIG. 10). For example, the second member (20) may be the frame (90) of FIG. 11 or the display assembly (14) of FIG. 14.

[0029] In one embodiment, the fingerprint sensor (50) may be disposed on the first member (10). For example, the fingerprint sensor (50) may be disposed on the support surface (10A) of the support portion (13). In one embodiment, the fingerprint sensor (50) may be supported by the first member (10). For example, the fingerprint sensor (50) may be supported by the support surface (10A) of the first member (10).

[0030] In one embodiment, the fingerprint sensor (50) may include a first side (50A) and a second side (50B). The first side (50A) may be supported by the first member (10). The second side (50B) may be opposite the first side (50A). The second side (50B) may face the elastic member (30) and the second member (20).

[0031] In one embodiment, the elastic member (30) may include an upper surface (30A) facing the second member (20) and a lower surface (30B) opposite the upper surface (30A) and facing the fingerprint sensor (50) and the first member (10). The elastic member (30) may be disposed on the fingerprint sensor (50). For example, the elastic member (30) may be disposed on the second surface (50B) of the fingerprint sensor (50). The lower surface (30B) of the elastic member (30) may be supported by the fingerprint sensor (50).

[0032] In one embodiment, the elastic member (30) may be in direct contact with the second member (20). For example, the upper surface (30A) of the elastic member (30) may be in direct contact with the second surface (20B) of the second member (20). The elastic member (30) may be in tight contact with the second member (20).

[0033] In one embodiment, the elastic member (30) may be disposed between the second member (20) and the fingerprint sensor (50) to provide elastic force to the second member (20). For example, the elastic member (30) interposed between the second member (20) and the fingerprint sensor (50) may be compressed as the first member (10) is coupled to the second member (20). As the elastic member (30) is compressed, the elastic member (30) may provide elastic force to the second member (20). In one embodiment, the elastic member (30) may have a first volume before the first member (10) and the second member (20) are coupled, and may have a second volume that is smaller than the first volume after the first member (10) and the second member (20) are coupled.

[0034] In one embodiment, the elastic force provided by the elastic member (30) to the second member (20) can improve the contact quality of the interface (e.g., the upper surface (30A)) between the elastic member (30) and the second member (20), thereby improving the performance of the fingerprint sensor (50) that transmits and receives ultrasonic waves through the interface. In addition, the elastic force provided by the elastic member (30) can prevent the fastening between the first member (10) and the second member (20) from being loosened, and can prevent the fingerprint sensor (50) mounted on the first member (10) from moving.

[0035] In one embodiment, the elastic member (30) may be configured to allow ultrasonic waves to pass through. For example, the elastic member (30) may be formed of a solid through which ultrasonic waves are transmitted. For example, the elastic member (30) may include natural rubber or a synthetic rubber including a resin (e.g., urethane). In another example, the elastic member (30) may be formed by curing a silicone elastic coating agent. However, the present invention is not limited to the above-described examples.

[0036] In one embodiment, the fingerprint sensor (50) may be configured to transmit or generate ultrasonic waves. Additionally, the fingerprint sensor (50) may be configured to receive or detect ultrasonic waves. For example, the fingerprint sensor (50) may include, but is not limited to, a piezoelectric element for generating and detecting ultrasonic waves.

[0037] In one embodiment, the fingerprint sensor (50) can transmit ultrasonic waves to an external object (e.g., a user's finger) that is in contact with or adjacent to the first surface (20A) of the second member (20). The ultrasonic waves transmitted from the fingerprint sensor (50) can pass through the elastic member (30) and the second member (20) and reach the external object. The fingerprint sensor (50) can receive ultrasonic waves reflected from the external object through the second member (20) and the elastic member (30). According to one embodiment, the electronic device can obtain fingerprint information (e.g., a fingerprint image) based on the ultrasonic waves transmitted and received by the fingerprint sensor (50).

[0038] In a comparative embodiment, the fingerprint sensor (50) may be attached to a counterpart with which the user's finger comes into contact via an adhesive. For example, the fingerprint sensor (50) of the comparative embodiment may be temporarily attached to the counterpart after being applied with a heat-curable resin (e.g., epoxy) and then using a light-curable adhesive (e.g., ultraviolet (UV) adhesive). Then, by performing a bubble removal and autoclaving process, the fingerprint sensor (50) may be completely attached to the counterpart. However, these processes have the problem that reworking after curing is difficult and includes multiple steps, which increases the process cost. In addition, since it is difficult to remove the fingerprint sensor (50) attached via an adhesive from the counterpart, the repair and replacement cost of the fingerprint sensor (50) may increase.

[0039] In contrast, according to one embodiment, the fingerprint sensor (50) can be assembled through a detachable mechanical fastening structure (e.g., first fastening parts (11, 21) and second fastening parts (12, 22)). This simplifies the process of assembling the fingerprint sensor (50) to the second member (20), and reduces the material cost required for the assembly process. In addition, since the fingerprint sensor (50) can be easily removed from the second member (20), the convenience of repair and replacement of the fingerprint sensor (50) is increased, and the cost thereof can be reduced.

[0040] FIG. 3 is a drawing illustrating an exemplary fingerprint sensor and a flexible printed circuit board according to one embodiment. Hereinafter, redundant descriptions of components having the same reference numerals may be omitted. In FIG. 3, the elastic member (30) and the second member (20) are omitted for convenience of explanation.

[0041] Referring to FIG. 3, a first surface (50A) of a fingerprint sensor (50) according to one embodiment may include a periphery defining an area of ​​the first surface (50A). The periphery of the first surface (50A) may include a first part (51), a second part (52), a third part (53), and a fourth part (54). The first part (51) may be adjacent to a first fastening portion (11). A second part (52) facing the first part (51) may be adjacent to a second fastening portion (12). For example, the first part (51) may be positioned between the first fastening portion (11) and the second part (52), and the second part (52) may be positioned between the second fastening portion (12) and the first part (51). The third part (53) can extend from one end of the first part (51) to one end of the second part (52). The fourth part (54) facing the third part (53) can extend from the other end of the first part (51) to the other end of the second part (52).

The portion (81) of the flexible printed circuit board (80) may be connected to the third part (53) of the fingerprint sensor (50), but is not limited thereto. For example, the portion (81) of the flexible printed circuit board (80) may extend below a first surface (50A) of the fingerprint sensor (50) and be connected to the first surface (50A).

[0043] In one embodiment, a shielding member (82) (e.g., a shield can) may be placed on a flexible printed circuit board (80). Electronic circuits may be mounted inside the shielding member (82). On the opposite side of the shielding member (82), a plate (83) may be placed to support the flexible printed circuit board (80) to mount the electronic circuits. The shape of the flexible printed circuit board (80) is not limited by the illustrated example, and various design modifications may be possible.

Referring to FIG. 4, a first member (10) may include a first fastening portion (11-1) and a second fastening portion (12-1). A second member (20) may include a first fastening portion (21-1) and a second fastening portion (22-1) protruding from a second surface (20B). First fastening holes that are in communication with each other may be formed in the first fastening portions (11-1, 21-1), respectively. The first fastening portions (11-1, 21-1) may be coupled through first screws (61) that penetrate the first fastening holes and are fastened to the first fastening holes. Second fastening holes that are in communication with each other may be formed in the second fastening portions (12-1, 22-1), respectively. The second fastening parts (12-1, 22-1) can be joined through a second screw (62) that passes through the second fastening holes and is fastened to the second fastening holes.

[0045] FIG. 5 is a diagram illustrating a fingerprint sensor on a first member according to an exemplary embodiment. Referring to FIG. 5, the electronic device according to an exemplary embodiment may further include a first adhesive layer (41) and a second adhesive layer (45).

[0046] In one embodiment, the first adhesive layer (41) may be disposed between the fingerprint sensor (50) and the elastic member (30). For example, the first adhesive layer (41) may be disposed between the second surface (50B) of the fingerprint sensor (50) and the lower surface (30B) of the elastic member (30). The first adhesive layer (41) may attach the elastic member (30) to the fingerprint sensor (50). The first adhesive layer (41) may include, but is not limited to, a resin adhesive (e.g., epoxy) or a double-sided tape.

[0047] In one embodiment, the second adhesive layer (45) may be disposed between the first member (10) and the fingerprint sensor (50). For example, the second adhesive layer (45) may be disposed between the support surface (10A) of the first member (10) and the first surface (50A) of the fingerprint sensor (50). The second adhesive layer (45) may attach the fingerprint sensor (50) to the first member (10). The second adhesive layer (45) may include, but is not limited to, a resin adhesive (e.g., epoxy) or a double-sided tape.

[0048] Alternatively, the first fastening portion (11) and the second fastening portion (12) of the first member (10) may be replaced with the first fastening portion (11-1) and the second fastening portion (12-1) of FIG. 4.

[0049] FIG. 6 is a diagram illustrating a fingerprint sensor on a first member according to an exemplary embodiment. Referring to FIG. 6, the fingerprint sensor (50) according to an exemplary embodiment may include a third surface (50C) extending from an edge of a first surface (50A) to an edge of a second surface (50B). The third surface (50C) may be referred to as a side surface of the fingerprint sensor (50).

[0050] In one embodiment, the first member (10) may include a protrusion (15). The protrusion (15) may be formed on the support surface (10A). The protrusion (15) may at least partially surround the third side (50C) of the fingerprint sensor (50). For example, when viewed in a direction perpendicular to the support surface (10A), the protrusion (15) may at least partially surround the periphery of the third side (50C) of the fingerprint sensor (50). In one embodiment, the protrusion (15) may extend from the support surface (10A) along the third side (50C) toward the edge of the second side (50B).

[0051] In one embodiment, the protrusion (15) can prevent movement of the fingerprint sensor (50) by surrounding the fingerprint sensor (50). In addition, the protrusion (15) can reduce process deviation by guiding the position where the fingerprint sensor (50) is mounted on the first member (10).

[0052] According to one embodiment, the electronic device may further include a cushioning member (70) disposed between the fingerprint sensor (50) and the first member (10). The cushioning member (70) may include, for example, a sponge, but is not limited thereto. The cushioning member (70) may alleviate physical impact that may be applied to the fingerprint sensor (50). Alternatively, the cushioning member (70) may be replaced with the second adhesive layer (45) of FIG. 5. Alternatively, the first fastening portion (11) and the second fastening portion (12) of the first member (10) may be replaced with the first fastening portion (11-1) and the second fastening portion (12-1) of FIG. 4. Additionally, an adhesive member (for example, the first adhesive layer (41) of FIG. 5) may be further disposed between the fingerprint sensor (50) and the elastic member (30).

[0053] Figures 7, 8, 9a, 9b, and 9c are drawings showing exemplary elastic members (30) according to one embodiment. Figures 7, 8, 9a, 9b, and 9c illustrate the elastic member (30) before the first member (10) and the second member (20) are fastened. Figure 9b is a drawing of the elastic member (30) of Figure 9a as viewed in a first direction (D1). Figure 9c is a drawing of the elastic member (30) of Figure 9a as viewed in a second direction (D2).

[0054] Referring to FIGS. 7, 8, 9a, 9b, and 9c, along with FIGS. 1 and 2, in one embodiment, the elastic member (30) may be configured such that the contact area with the second member (20) increases as the first member (10) and the second member (20) are fastened together. For example, the upper surface (30A) of the elastic member (30) may be formed to be convex toward the second member (20). For example, the upper surface (30A) may be formed as a convex surface having a line segment (e.g., line segment (L1) or line segment (L2)) or a point (e.g., point (P)) as a vertex or peak. The line segment or the point of the upper surface (30A) forming the vertex or the peak may be located at the geometric center of the upper surface (30A), but is not limited thereto.

[0055] In one embodiment, during the process of fastening the first member (10) and the second member (20), the area where the elastic member (30) first comes into contact with the second member (20) may be a first area. Thereafter, when the first member (10) and the second member (20) are completely fastened, the elastic member (30) may come into contact with the second member (20) by a second area that is larger than the first area.

[0056] In one embodiment, during the process of fastening the first member (10) and the second member (20), the form in which the elastic member (30) first comes into contact with the second member (20) may be a point contact or a line contact. Thereafter, when the first member (10) and the second member (20) are completely fastened, the form in which the elastic member (30) comes into contact with the second member (20) may be a surface contact. Accordingly, air bubbles between the elastic member (30) and the second member (20) can be removed, and the surface contact characteristics between the upper surface (30A) of the elastic member (30) and the second surface (20B) of the second member (20) can be improved.

[0057] Referring to FIG. 7, the edge of the upper surface (30A) of the elastic member (30) may include a first part (31), a second part (32), a third part (33), and a fourth part (34). The first part (31) may be spaced apart from and parallel to the second part (32). The third part (33) may connect one end of the first part (31) and one end of the second part (32). The fourth part (34) may be spaced apart from and parallel to the third part (33). The fourth part (34) may connect the other end of the first part (31) and the other end of the second part (32).

The sixth section (326) of the second part (32) can face the third section (313) of the first part (31).

[0059] In one embodiment, the upper surface (30A) of the elastic member (30) may include a central region (71) and a peripheral region (75) that partially surrounds the central region (71). The peripheral region (75) may extend from the central region (71) to a portion of an edge of the upper surface (30A). For example, the peripheral region (75) may include a first region (751) and a second region (752). The first region (751) may extend from a first section (311) of the first part (31), along a third part (33), to a fourth section (324) of the second part (32). The second region (752) may extend from a second section (312) of the first part (31), along a fourth part (34), to a fifth section (325) of the second part (32). The first region (751) and the second region (752) may be spaced apart from each other, and a central region (71) may be formed between the first region (751) and the second region (752). The central region (71) may extend from the third section (313) of the first part (31) to the sixth section (326) of the second part (32) in a direction parallel to the third part (33) or the fourth part (34).

[0060] In one embodiment, the first distance between the central region (71) and the lower surface (30B) may be greater than the second distance between the peripheral region (75) and the lower surface (30B). The first distance and the second distance may be based on a direction perpendicular to the lower surface (30B).

[0061] In one embodiment, the second distance may be greatest at the edge between the central region (71) and the peripheral region (75), and may be smallest at the third part (33) and the fourth part (34). The second distance may gradually increase from the third part (33) to the central region (71), and may gradually increase from the fourth part (34) to the central region (71).

[0062] In one embodiment, the central region (71) may include a line segment (L1) extending from the third section (313) of the first part (31) to the sixth section (326) of the second part (32). The line segment (L1) may be spaced apart from the peripheral region (75). The line segment (L1) may be parallel to the third part (33) and the fourth part (34).

[0063] In one embodiment, the first distance may be greatest at the line segment (L1) and smallest at the edge between the central region (71) and the peripheral region (75). The first distance and the second distance may gradually increase from the third part (33) to the line segment (L1).
