Abstract
Description
Electronic device comprising a light-emitting structure
[0001] Embodiments of the present disclosure relate to electronic devices including light-emitting structures.
[0002] Recently, wristwatch-style electronic devices are being equipped with various sensors capable of measuring a user's biometric information. For example, one such sensor may be an optical sensor comprising at least one light-emitting element and a light-receiving element. The optical sensor can measure a user's biometric information using light of a specific wavelength.
[0003] The above information may be provided solely as background information to aid in understanding the present disclosure. No determination is made, and no assertion is made, as to whether any of the above is applicable to prior art in connection with the present disclosure.
[0004] The required wavelength of light may vary depending on the biometric information. Miniaturized electronic devices, such as wristwatches, are equipped with light sources that emit light of only a specific wavelength range. Therefore, many light sources with various wavelengths may be required to measure various biometric information. However, as the number of light sources increases, the location of the emitted light varies, and thus the location at which it reaches the biometric specimen (e.g., skin) may vary depending on the wavelength range, resulting in differences in the light path. For example, to reduce the difference in the light path, electronic devices may be equipped with a light focusing element. However, light focusing elements are bulky and may not be suitable for miniaturized electronic devices.
[0005] Aspects of the present disclosure may address at least the problems and / or disadvantages mentioned above, and provide at least the advantages described below. An electronic device according to one embodiment of the present disclosure may include at least one light-emitting structure including a plurality of light sources that emit light of different wavelengths.
[0006] Additional aspects of the present disclosure will be described in part below, and in part will be obvious from the description, or may be learned by practice of the disclosed embodiments.
[0007] According to one embodiment of the present disclosure, an electronic device may include a housing including a first surface, a second surface opposite to the first surface, and a side surface surrounding the first surface and the second surface. According to one embodiment, the electronic device may include a substrate disposed inside the housing. According to one embodiment, the electronic device may include at least one light-emitting structure formed in a bar shape and disposed on the substrate so as to face the second surface. According to one embodiment, the electronic device may include a plurality of light sources arranged at a specified interval on the at least one light-emitting structure formed in the bar shape and emitting light of different wavelengths. According to one embodiment, the at least one light-emitting structure may be electrically connected to the substrate through soldering while at least one of the at least one light-emitting structure is inclined at a specific angle.
[0008] According to one embodiment of the present disclosure, at least one light-emitting structure including a plurality of light sources emitting light of different wavelengths is set at a specific angle, and each of the at least one light-emitting structure set at the specific angle can be electrically connected to a substrate through soldering. As the at least one light-emitting structure is electrically connected to the substrate through soldering while being set at the specific angle, the electronic device can cause the plurality of light sources included in the at least one light-emitting structure to emit light of different wavelengths at the set specific angle. As the plurality of light sources included in the at least one light-emitting structure set at the specific angle emit light of different wavelengths, the electronic device can make the positions where they come into contact with a biometric specimen (e.g., skin) of each wavelength similar. Accordingly, the electronic device can obtain various reliable biometric information. In addition, since the electronic device includes at least one light-emitting structure including a plurality of light sources emitting light of different wavelengths instead of a bulky light focusing element, it not only contributes to miniaturization of the electronic device but also reduces the difficulty of the process.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).
[0051] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate.

[0139] Reference numerals of FIG. 9 according to one embodiment <950> is a drawing of a substrate (601), at least one insulator, and a first light-emitting structure (520) viewed from one side. The first insulator (920) disposed on at least a portion of a first surface (5201) of the first light-emitting structure (520) may include a plurality of first insulators. The plurality of first insulators may include a first-first insulator (9201), a first-second insulator (9202), a first-third insulator (9203), a first-fourth insulator (9204), a first-fifth insulator (9205), a first-sixth insulator (9206), a first-seventh insulator (9207), a first-eighth insulator (9208), and a first-ninth insulator (9209).
[0140] In one embodiment, each of the plurality of first insulators may be disposed between the plurality of light sources included in the first light-emitting structure (520) for insulation between the plurality of light sources. For example, the 1-1 insulator (9201) may be disposed between the first side (5203) of the first light-emitting structure (520) and the 1-1 light source (521). The 1-2 insulator (9202) may be disposed between the 1-1 light source (521) and the 1-2 light source (523). The 1-3 insulator (9203) may be disposed between the 1-2 light source (523) and the 1-3 light source (525). The 1-4 insulator (9204) may be disposed between the 1-3 light source (525) and the 1-4 light source (527). The first-fifth insulator (9205) may be disposed between the first-fourth light source (527) and the first-fifth light source (529). The first-sixth insulator (9206) may be disposed between the first-fifth light source (529) and the first-sixth light source (531). The first-seventh insulator (9207) may be disposed between the first-sixth light source (531) and the first-seventh light source (533). The first-eighth insulator (9208) may be disposed between the first-seventh light source (533) and the first-eighth light source (535). The first-ninth insulator (9209) may be disposed between the first-eighth light source (535) and the second side (5204) of the first light-emitting structure (520).
[0141] In one embodiment, a first insulator (920) is disposed on at least a portion of a first surface (5201) of a first light-emitting structure (520), a second insulator (930) is disposed on at least a portion of a first surface (5401) of a second light-emitting structure (540), and an n-th insulator (940) is disposed on at least a portion of a first surface (5701) of an n-th light-emitting structure (570), and then, through electrical connection structures such as soldering members (615, 620, 625, 630, 635, 640), the first light-emitting structure (520), the second light-emitting structure (540), ..., the n-th light-emitting structure (570) can be electrically connected to the substrate (601).
[0142] In FIG. 9 according to various embodiments, at least one insulator (e.g., a first insulator (920), a second insulator (930), ..., an n-th insulator (940)) is described as being disposed on a first surface of each light-emitting structure (e.g., a first surface (5201) of a first light-emitting structure (520), a first surface (5401) of a second light-emitting structure (540), ..., a first surface (5701) of an n-th light-emitting structure (570)), but is not limited thereto. For example, instead of being disposed on the first side of each light-emitting structure, at least one insulator (e.g., the first insulator (920), the second insulator (930), ..., the n-th insulator (940)) may be disposed on the second side of each light-emitting structure (e.g., the second side (5202) of the first light-emitting structure (520), the second side (5402) of the second light-emitting structure (540), ..., the second side (5702) of the n-th light-emitting structure (570)).
[0143] As seen in FIG. 9 according to various embodiments, since an insulator (920, 930, 940) is placed between a plurality of light sources included in each light-emitting structure, not only is the plurality of light sources insulated from each other to prevent shorts, but each light-emitting structure can be firmly fixed to the substrate (601), thereby increasing structural rigidity.
[0144] FIG. 10 is a drawing for explaining a method of measuring multiple biometric information of a user through multiple light sources included in at least one light-emitting structure (520, 540, ... 570) according to one embodiment of the present disclosure.
[0145] According to various embodiments, in FIGS. 6A, 6B, and 7 to 9, at least one light-emitting structure (e.g., the first light-emitting structure (520), the second light-emitting structure (540), ..., the n-th light-emitting structure (570) of FIG. 6A) of a first biometric sensor (e.g., the first biometric sensor (430) of FIG. 4) is soldered (e.g., soldered through a soldering member (e.g., the first soldering member (615), the second soldering member (620), the third soldering member (625), the fourth soldering member (630), the fifth soldering member (635), and / or the sixth soldering member (640) of FIGS. 6A and 6B) or a wire (e.g., the first wire (720) of FIG. 7, the second Although it has been described as being electrically connected to the substrate (601) through a wire (730) and / or a third wire (740), it is not limited thereto.
[0146] For example, referring to FIG. 10, the first light-emitting structure (520), the second light-emitting structure (540), ..., the nth light-emitting structure (570) of the first biometric sensor (430) can be electrically connected to the substrate (601) through soldering (or wire) while being tilted at a specific angle.
[0147] In one embodiment, the electronic device (200) may include a back plate (1010) (e.g., back plate (493) of FIG. 4), and when the electronic device (200) is worn (or secured) to a part of the user's body (e.g., wrist), at least a portion of the back plate (1010) may be in contact with the part of the user's body (e.g., wrist).
[0148] In one embodiment, at least one of the first light-emitting structure (520), the second light-emitting structure (540), ..., the n-th light-emitting structure (570) may be electrically connected to the substrate (601) through soldering (or wire) while tilted at a specific angle so that light emitted through a plurality of light sources included in each light-emitting structure (e.g., the first light-emitting structure (520), the second light-emitting structure (540), ..., the n-th light-emitting structure (570)) reaches the light-irradiating area (1020) (e.g., the skin of a body part (e.g., the wrist) of the user) (e.g., so that light emitted through each light source is focused onto the light-irradiating area (1020).
[0149] In one embodiment, a specific angle at which at least one of the first light-emitting structure (520), the second light-emitting structure (540), ..., the nth light-emitting structure (570) is tilted can be set based on the distance between each light-emitting structure and the light irradiation area (1020).
[0150] It is not limited thereto, and the specific angle at which at least one of the first light-emitting structure (520), the second light-emitting structure (540), ..., the nth light-emitting structure (570) is tilted may be set in consideration of the distance between each light-emitting structure and the light irradiation area (1020) and the light reflected from the rear plate (1010) existing between each light-emitting structure and the light irradiation area (1020).
[0151] For example, considering the distance between the first light-emitting structure (520) and the light-emitting area (1020) and the light being reflected from the back plate (1010) existing between the first light-emitting structure (520) and the light-emitting area (1020), the first light-emitting structure (520) can be tilted at a specific angle (e.g., about 0.1 to 10 degrees) (1030). In addition, considering the distance between the second light-emitting structure (540) and the light-emitting area (1020) and the light being reflected from the back plate (1010) existing between the second light-emitting structure (540) and the light-emitting area (1020), the second light-emitting structure (540) can be maintained in an untilted state (e.g., perpendicular to the substrate (601)). In addition, considering the distance between the nth light-emitting structure (570) and the light irradiation area (1020) and the light being reflected from the back plate (1010) existing between the nth light-emitting structure (570) and the light irradiation area (1020), the nth light-emitting structure (570) can be tilted at a specific angle (e.g., about 0.1 to 10 degrees) (1040). In other words, in a state where the first light-emitting structure (520) and the nth light-emitting structure (570) are tilted at a specific angle (e.g., about 0.1 to 10 degrees), and the second light-emitting structure (540) is not tilted at a specific angle (e.g., perpendicular to the substrate (601)), the first light-emitting structure (520), the second light-emitting structure (540), ..., the nth light-emitting structure (570) can be soldered (or wired) to be electrically connected to the substrate (601).
[0152] In one embodiment, when an input (or signal) for measuring a biosignal is detected, each light source included in the first light-emitting structure (520), each light source included in the second light-emitting structure (540), and each light source included in the n-th light-emitting structure (570) may sequentially emit light of different wavelengths through different optical paths.

Each of the plurality of light sources included in the first light-emitting structure (520) may sequentially emit light of different wavelengths through different optical paths, and the light of different wavelengths sequentially emitted through the different optical paths may reach the light irradiation area (1020). The processor (120) can cause the plurality of light sources included in the second light-emitting structure (540) to sequentially emit light at an angle from the substrate (601) in a vertical state.

The processor (120) can cause the plurality of light sources included in the n-th light-emitting structure (570) that is tilted (1040) at a specific angle (e.g., about 0.1 to 10 degrees) to sequentially emit light at a specific angle. Each of the plurality of light sources included in the nth light emitting structure (570) can sequentially emit light of different wavelengths through different light paths (e.g., different light paths from the plurality of light sources included in the first light emitting structure (520) and the second light emitting structure (540), and the light of different wavelengths sequentially emitted through different light paths can reach the light irradiation area (1020).
[0153] In one embodiment, each light source included in the first light-emitting structure (520), each light source included in the second light-emitting structure (540), and each light source included in the n-th light-emitting structure (570) sequentially emit light of different wavelengths through different light paths, thereby obtaining various bio-information.

The light (1215, 1245) emitted through the light-emitting sensor (1210, 1240) of the second biometric sensor (1203) can be reflected from the light-irradiating area (1020) (e.g., skin of a body part of the user (e.g., wrist)). The light-receiving sensor (1205, 1235) can receive the light reflected from the light-irradiating area (1020). The processor (120) can measure (or obtain) at least one second biometric information of the user based on the light received through the light-receiving sensor (1205, 1235).
[0171] In FIG. 12A according to various embodiments, the first biometric sensor (1201) and the second biometric sensor (1203) are described as being arranged on the same plane of the substrate (601), but this is not limited thereto. In this regard, various embodiments will be described in FIG. 12B described below.
[0172] FIG. 12b is a diagram illustrating a state in which a plurality of biometric recognition sensors are arranged according to one embodiment of the present disclosure.
[0173] Referring to FIG. 12B, an electronic device (e.g., electronic device (101) of FIG. 1, electronic device (200) of FIGS. 2 to 4) may include a first biometric sensor (1201) (e.g., first biometric sensor (430) of FIG. 4) and a second biometric sensor (1203).
[0174] The first biometric sensor (1201) and the second biometric sensor (1203) of FIG. 12B according to various embodiments are substantially the same as the first biometric sensor (1201) and the second biometric sensor (1203) of FIG. 12A described above, and thus, a detailed description thereof may be replaced with the description of FIG. 12A.
[0175] In one embodiment, the first biometric sensor (1201) and the second biometric sensor (1203) may be disposed on a substrate (e.g., substrate (601) of FIG. 6A). For example, the first biometric sensor (1201) and the second biometric sensor (1203) may be disposed on different planes of the substrate (601). For example, a groove may be formed in a portion of the substrate (601), and the first biometric sensor (1201) may be disposed in the formed groove, and the second biometric sensor (1203) may be disposed in another portion of the substrate (601).
[0176] For another example, the first biometric sensor (1201) and the second biometric sensor (1203) may each be disposed on different substrates. For example, the first biometric sensor (1201) may be disposed on the substrate (601), and the second biometric sensor (1203) may be disposed on the printed circuit board (480) illustrated in FIG. 4. In this case, a portion of the printed circuit board (480) overlapping the first biometric sensor (1201) may be formed of a material that is transparent to light (e.g., infrared ray, visible light). However, the present invention is not limited thereto, and a portion of the printed circuit board (480) overlapping the first biometric sensor (1201) may have a hole formed therein so that light emitted by the first biometric sensor (1201) may reach the light irradiation area (1020).
[0177] In FIG. 12B according to one embodiment, the distance between the back plate (1010) (e.g., the back plate (493) of FIG. 4) and the second biometric sensor (1203) may be greater than the distance between the back plate (1010) and the first biometric sensor (1201). For example, the plurality of light sources included in the second biometric sensor (1203) may include laser diodes. Since the laser diode has a straight line and the probability of light spreading is low, the second biometric sensor (1203) may be placed further from the back plate (1010) than the first biometric sensor (1201).

[0189] In one embodiment, the processor (120) may operate the driving unit (1405) and process a digital signal received from the ADC (1425). For example, the processor (120) may control the driving unit (1405) to adjust the current supplied to the plurality of light sources based on signals from an external temperature and / or a monitoring circuit (e.g., a first monitoring circuit (1410), a second monitoring circuit (1415)).
[0190] In one embodiment, the driving unit (1405) can control the operation of each of the plurality of light sources having different wavelengths included in the first light-emitting structure (520) under the control of the processor (120). For example, the driving unit (1405) can turn on or off each of the plurality of light sources included in the first light-emitting structure (520) under the control of the processor (120). For example, the driving unit (1405) can supply current to the first light-emitting structure (520) under the control of the processor (120) to control the plurality of light sources to sequentially emit light of the corresponding wavelengths.

[0202] In FIG. 15 according to one embodiment, the x-axis may represent wavelength (nm (nanometers)) (1505), and the y-axis may represent absorption rate (1510).
[0203] Referring to FIG. 15, a processor (e.g., the processor (120) of FIG. 1) of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2 to 4) can sequentially emit light through a plurality of light sources included in each light-emitting structure (e.g., the first light-emitting structure (520), the second light-emitting structure (540), ..., the n-th light-emitting structure (570) of FIG. 6A) having different wavelength bands, and measure light reflected (and / or scattered light) from a back plate (e.g., the back plate (1010) of FIG. 10) and / or a light irradiation area (e.g., the light irradiation area (1020) of FIG. 10) (e.g., the skin of a body part of a user (e.g., the wrist)).
[0204] For example, the 1-1 wavelength band (1515) (e.g., λ) is transmitted through the 1-1 light source (521) of the light-emitting structure (520). 1,1 ) is radiated, the monitoring circuit (e.g., the first monitoring circuit (1410), the second monitoring circuit (1415) of FIG. 14) can obtain (or receive) at least some of the light reflected or scattered by the back plate (1010) or the light (e.g., 1451, 1453, 1455, 1457 of FIG. 14).

The amount (or intensity) of the light reflected by the rear plate (1010) or the scattered light (1451, 1453, 1455, 1457) is M 1,1 , and the amount of light absorbed and reflected (e.g., 1461, 1463, 1465, 1467 in Fig. 14) in the light irradiation area (1020) (e.g., skin of a part of the user's body (e.g., wrist)) is defined as R 1,1 Let us explain assuming that it is defined as R. In this case, the processor (120) is R 1,1 / M1,1 Based on this, the 1-1 point (1541) can be created.
[0205] For another example, the 1-2nd light source (523) of the light-emitting structure (520) emits light in the 1-2nd wavelength band (1520) (e.g., λ 1,2 ) is radiated, the monitoring circuit (e.g., the first monitoring circuit (1410), the second monitoring circuit (1415) of FIG. 14) can obtain (or receive) at least some of the light reflected or scattered by the rear plate (1010).

In this case, the processor (120) is R 1,2 / M 1,2 Based on this, the 1st-2nd point (1543) can be created.
[0206] In the same manner as above, the n-1 wavelength band (1525) (e.g., λ) is transmitted through the n-1 light source to the n-8 light source of the n-th light-emitting structure (570). n,1 ) to the n-8 wavelength band (1530) (e.g. λ n,8 ) is radiated, the monitoring circuit (e.g., the first monitoring circuit (1410), the second monitoring circuit (1415) of FIG. 14) can obtain (or receive) at least some of the light reflected or scattered by the back plate (1010). In addition, when light of the first-second wavelength band is radiated through the first-second light source (523) of the light-emitting structure (520), the light detection circuit (e.g., the first light detection circuit (1430), the second light detection circuit (1435) of FIG. 14) can obtain (or receive) light absorbed and reflected by the light irradiation area (1020) (e.g., the skin of a part of the user's body (e.g., the wrist)).
