This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2017-0162729, filed on Nov. 30, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein its entirety.
The present disclosure relates to a wearable electronic device including a fingerprint sensor.
Electronic devices, such as mobile devices which include smartphones are storing increasing amount of a user's personal information. Accordingly, it has become increasingly important to authenticate the user to avoid unauthorized access and misuse of a person's private information.
The above information is presented as background information only to assist with an understanding of the present 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 present disclosure.
User authentication technologies include a fingerprint recognition technology. The electronic device including a fingerprint sensor, to which a fingerprint recognition technology is applied, may authenticate a user by comparing collected fingerprint information with fingerprint information registered through a fingerprint registering process when the user is authenticated.
However, in a wearable electronic device such as a wearable watch, the front part of the wearable electronic device is thicker compared to a smartphone device. Accordingly, it is more difficult to recognize a fingerprint using a structure where a fingerprint sensor is disposed under a display. For example, in the wearable electronic device, it is difficult to receive refracted light necessary for sensing a fingerprint. This can be due to crosstalk, such as internal diffused reflection, due to the thickness of the front part of the wearable electronic device. Further, in the wearable electronic device, it is difficult to collect light that is necessary for sensing a fingerprint because the distance between the surface of the front part and the fingerprint sensor is relatively large, and interference caused by the display.
Aspects of the present disclosure may address at least the above-mentioned problems and/or disadvantages and may provide at least the advantages described below. Accordingly, an aspect of the present disclosure may provide an electronic device including a fingerprint sensor that may support an improved fingerprint sensing function even in a structure of a wearable electronic device having a relatively thick front part.
In accordance with an aspect of the present disclosure, there is provided an electronic device including a transparent member, a display, wherein at least part of the display is disposed under the transparent member, wherein the display includes an active area, in which a plurality of pixels capable of outputting light to display contents, a biometric sensor, wherein at least part of the biometric sensor is disposed in a first area outside the active area, and a reflector positioned to direct light reflected by an external object in contact with at least a partial area of the transparent member to the biometric sensor through at least a portion of the transparent member, wherein at least some of the plurality of pixels are positioned to irradiate the external object, thereby resulting in the light reflected by the external object.
In accordance with another aspect of the present disclosure, there is provided a wearable electronic device comprising a front plate having a specific transparency, a display under the front plate, a housing, at least a portion of which surrounds an edge of the front plate, a support member on which the front plate and the display are positioned, a rear plate on which the support member is positioned and coupled to the housing, and a fingerprint sensor, wherein at least part of the fingerprint sensor is disposed on a side of the front plate and under an edge of the housing and configured to receive light related to a fingerprint of a finger in contact with a specific area of the front plate to and receive fingerprint information from the fingerprint.
According to embodiments of the present disclosure, even a wearable electronic device including a relatively thick front part may provide an excellent fingerprint sensing function.
In addition, the present disclosure may provide various effects that are directly or indirectly recognized.
Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses certain embodiments of the present disclosure.
The above and other aspects, features, and advantages of certain embodiments of the present disclosure will be more apparent from the following description taken in conjunction with the accompanying drawings, in which:
With regard to description of drawings, the same or similar components may be marked by the same or similar reference numerals.
Hereinafter, certain embodiments of the present disclosure will be described with reference to the accompanying drawings. Accordingly, those of ordinary skill in the art will recognize that modification, equivalent, and/or alternative on the certain embodiments described herein can be variously made without departing from the scope and spirit of the present disclosure.

For example, the wearable electronic device 300 may sense a fingerprint by using an RGB camera of a relatively low resolution because the camera for sensing a fingerprint is disposed on a side of the front plate 301, instead of the lower side of the display 320. Further, the wearable electronic device 300 according to certain embodiments may secure proper focal distance that is necessary for the fingerprint sensor 380 to receive light by using reflection sensor 390. For example, the distance between the fingerprint sensor 380 and the reflector 390 of the wearable electronic device 300 may be equal, substantially equal, or within 10 percent of the focal distance of the fingerprint sensor 380.

The upper positioning part 531 may include a vessel form, the bottom of which is flat as a whole. The fingerprint sensor 580 may be fixed to an area of the upper positioning part 531, which corresponds to the sensor disposition recess 501c. The first reflection member 590a may be disposed in a first reflection member area 535a of the upper positioning part 531, which corresponds to the reflection member disposition recess 501d. The first reflection member area 535a may have a surface form having a specific inclination such that the first reflection member 590a is fixed while being inclined at a specific inclination.
The fingerprint sensor 580 may include a sensor part 581 and a sensor wiring part 582. The fingerprint sensor 580 may be disposed under the housing 506 and in an area of the side surface of the front plate 501, which corresponds to the sensor disposition recess 501c. The fingerprint sensor 580 (or a light receiving part) may be disposed to face the first reflector 590a while crossing a transverse direction of the front plate 501. According to various embodiments, the display 520 may include an active area in which pixels are disposed, and an inactive area disposed on an outskirt of the active area, and not visible when viewed from directly above the electronic device 500. The fingerprint sensor 580 may be disposed in a first area (or a first area of a specific location of the inactive area) except for the active area of the display 520.
The reflector 590a may be disposed on one side of the upper positioning part 531 of the support member 530 (e.g., one side of an area corresponding to the reflection. member disposition recess 501d). The reflector 590a, for example, may have front and rear surfaces thereof are flat and be configured to reflect light on the front surface thereof. The first reflector 590a is configured to be focused on a central portion of the front plate 501. The first reflector 590a, may be position to direct light from the central portion of the front plate 501 (e.g., optical path 598 is changed to optical path 599) to the fingerprint sensor 580 disposed on an opposite side with respect to the central area 501a of the front plate 501. In this regard, the first reflector 590a may be positioned in the first reflector area 535a having a specific inclination. According to certain embodiments, the first fingerprint member 590a may be disposed in a second area (or a second area of a specific location of an inactive area of the display 520) outside of the active area of the display 520.

The first reflector 590a can be inclined at an angle such that a line from the top of the central portion of the front plate 501 makes an angle of incidence that result in an angle of refraction, wherein a line from the point of incidence is substantially parallel to the base of the housing.
According to an embodiment, the wearable electronic device 500 may irradiate light to a specific area (e.g., a central area) of the front plate 501 through the light irradiation area 520a of the display 520. Accordingly, the light reflected by a fingerprint 10 of a finger in contact with a surface of the front plate 501 is reflected by the first reflector 590a and the light reflected by the first reflector 590a may be directed to the fingerprint sensor 580 through a side of the front plate 501. In this process, because the light related to sensing of a fingerprint travels through the front plate 501, the fingerprint sensor 580 may sense a fingerprint with better resolution than a fingerprint sensor 580 that is disposed under the display 520.

The front plate 601 may include a central area 601a formed such that the thickness of a central portion thereof is larger than the thickness of an edge portion thereof and an edge 601b surrounding a periphery of the central area 601a, and a first reflector disposition part 601d_1 and a sensor disposition recess 601c may be provided on opposite sides of the edge 601b. The first reflector disposition part 601d_1 and the sensor disposition recess 601c may be disposed to be symmetrical, substantially symmetrical, or within 1˜10% (for example, 5%) deviation of symmetrical to each other with respect to the central area 601a. The sensor disposition recess 601c may be formed while one side of the edge 601b is removed.
The first reflector disposition part 601d_1 protrudes from a specific area of a side of the central area 601a outwards, and the sectional area of the first reflector disposition part 601d_1 gradually decreases from the upper side toward the lower side to form a specific inclined surface. The angle of the inclined surface of the first reflector disposition part 601d_1 may be configured such that light may be irradiated toward the fingerprint sensor 680 disposed on an opposite side of the front plate 601 by changing an optical path of light or directing light reflected from the center of the front plate 601 (e.g., by changing optical path 698 to optical path 699) while the attached first reflector 690a faces a central portion of the front plate 601. The first reflector 690a may be fixed to the first reflector disposition part 601d_1.
The support member 630 may include an upper positioning part 631 on which the front plate 601 and the display 620 are positioned, a lower positioning part 632 on which the battery 670 is positioned, a first wiring hole 633, through which the sensor wiring part 680 disposed in the fingerprint sensor 682 passes, and a second wiring hole 634, through which the display wiring part 621 passes. The upper positioning part 631 may include a vessel form, the bottom of which is flat as a whole. An area of one side of the upper positioning part 631, in which the fingerprint sensor 680 is disposed, may be relatively thin as compared with the other areas. A first reflector area 635a of one side of the upper positioning part 631, in which the first reflector 690a is disposed, may protrude further than the edge area thereof. For example, the first reflector area 635a may be configured such that the sectional area thereof decreases from the lower side toward the upper side. A specific interval may be provided between the first reflector area 635a and the first reflector 690a or an adhesive may be disposed between the first reflector area 635a and the first reflector 690a.
The first reflector 690a may be disposed in the first reflector disposition part 601d_1 of the front plate 601. The first reflector 690a, for example, may be configured such that front and rear surfaces thereof are flat and be configured to reflect light on the front surface thereof. The first reflector 690a may be configured such that a focus thereof faces a central portion of the front plate 601, and may be disposed such that the light received from the central portion of the front plate 601 may be directed to the fingerprint sensor 680 disposed on an opposite side of the front plate 601 with respect to the central area 601a of the front plate 601. In this regard, the first reflector 690a may be bonded and fixed to the first reflector disposition part 601d_1 having a specific inclination.
According to an embodiment, the wearable electronic device 600 may irradiate light to a specific area (e.g., a central area) of the front plate 601 through the light irradiation area 620a of the display 620. Accordingly, as the light reflected by the fingerprint 10 in contact with a surface of the front plate 601 is reflected by the first reflector 690a attached to one side of the front plate 601, the light reflected by the first reflector 690a may be directed to the fingerprint sensor 680 through a side surface of the front plate 601. In this process, because the first reflector 690a is directly bonded to the surface of the front plate 601, the first reflector 690a may refract the light that is necessary for sensing a fingerprint toward the fingerprint sensor 680 without additional refraction of the light due to an additional medium (e.g., air).

The second reflector disposition part 601d_2 may have an inclined surface, a sectional area of which gradually decreases as it goes from the upper side to the lower side, and the inclined surface may have a specific curvature. Accordingly, the second reflector disposition part 601d_2 may protrude to be rounded outwards when viewed from the outside.
The second reflector 690b may be disposed in the second reflector disposition part 601d_2 of the front plate 601. Because the second reflector disposition part 601d_2 has a specific curvature as described above, the second reflector 690b may be concave (when viewed from a central portion of the front plate 601 or convex when viewed from a direction of the rear plate 607) while having a specific curvature to correspond to the shape of the second reflector disposition part 601d_2. The second reflector 690b having a form of a concave mirror may be position to be focused at the top of the center of the front plate 601 or be disposed such that a focus thereof faces the center of the front plate 601.
In the above-mentioned wearable electronic device 600, the second reflector 690b may converge light reflected by the fingerprint 10 in contact with the front plate 601 more efficiently and direct the converged light to the fingerprint sensor disposed on a side surface of the front plate 601, which is opposite to the first side surface because the second reflector 690b is formed to be concave in a direction that faces a specific portion (e.g., a portion which the fingerprint 10 contacts or a central portion) of the front plate 601 and is fixed to the front plate 601 while directly facing the front plate 601.
