Abstract
Description
TECHNICAL FIELD
[0001] The disclosure relates to an electronic device including a light emitting structure. BACKGROUND
[0002] Recently, electronic devices in the form of a watch have been equipped with various sensors capable of measuring biological information of a user. For example, an optical sensor including at least one light emitting element and at least one light receiving element can be included as one of the various sensors. The optical sensor can measure biological information of a user by using light in a specific wavelength range.
[0003] The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. SUMMARY
[0004] TECHNICAL PROBLEM The required light wavelength range varies according to biological information. Since a small electronic device such as a watch has a light source that emits light only in a specific wavelength range, many light sources having various wavelength ranges can be required to measure various biological information. However, as the number of light sources increases, a position deviation of the emitted light increases, and a position at which light reaches a biological feature sample (for example, skin) varies according to the wavelength range, which can cause a difference between light paths. For example, the electronic device can be equipped with an optical focusing element to reduce the difference between the light paths. However, since the optical focusing element has a large volume, the optical focusing element can not be suitable for a small electronic device.
[0005] Aspects of the disclosure are to address at least the above-mentioned problems and / or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device including at least one light emitting structure including a plurality of light sources configured to emit light of different wavelength ranges.
[0006] Additional aspects will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following description and / or can be learned by practice of the embodiments.
[0007] SOLUTION TO PROBLEM According to an aspect of the disclosure, an electronic device is provided. The electronic device includes a housing including a first surface, a second surface opposite the first surface, and a side surface surrounding the first surface and the second surface, a substrate disposed in the housing, at least one light emitting structure disposed on the substrate to be directed to the second surface and formed in a bar shape, and a plurality of light sources configured to emit light of different wavelength ranges and disposed on the at least one light emitting structure formed in a bar shape at a specified interval, wherein the at least one light emitting structure is electrically connected to the substrate by soldering in a state in which at least one of the at least one light emitting structure is inclined at a specific angle.
[0008] Advantages of the Invention According to an aspect of the disclosure, at least one light emitting structure including a plurality of light sources configured to emit light of different wavelength ranges is configured at a specific angle and electrically connected to a substrate by soldering in a state in which the at least one light emitting structure is configured at the specific angle, so that the electronic device can allow the plurality of light sources included in the at least one light emitting structure to emit light of different wavelength ranges at the specific angle. The plurality of light sources included in the at least one light emitting structure configured at the specific angle emit light of different wavelength ranges so that positions at which light of respective wavelength ranges reaches a biometric sample (e.g., skin) can be similar to each other. Accordingly, the electronic device can reliably acquire various biometric information. In addition, instead of an optical focusing element having a large volume, the electronic device includes at least one light emitting structure including a plurality of light sources configured to emit light of different wavelength ranges, which can help to reduce the size of the electronic device and reduce process difficulty.

However, the disclosure is not limited thereto. For example, at least one light absorbing structure (e.g., the first light absorbing structure (820), the second light absorbing structure (830),..., and the n-th light absorbing structure (840)) can be additionally included in the structure shown in Figure 7 .

[0135] Figure 9 is a view for explaining a structure in which at least one insulator is additionally disposed in the structure shown in Figure 6a and Figure 6b . In the following description with reference to
[0136] In the following description with reference to Figure 9 , only a configuration different from the configuration described with reference to Figure 6a and Figure 6b will be described.
[0137] With reference to reference numeral <910> in Figure 9 according to an embodiment, an electronic device (e.g., the electronic device (101) in Figure 1 or the electronic device (200) in Figure 2 to Figure 4 ) can include at least one insulator disposed on at least a portion of a first surface (e.g., the first surface (5201) of the first light emitting structure (520), the first surface (5401) of the second light emitting structure (540),..., and the first surface (5701) of the n-th light emitting structure (570)) of each light emitting structure (e.g., the first light emitting structure (520), the second light emitting structure (540),..., and the n-th light emitting structure (570)).

[0139] According to an embodiment Figure 9 The reference numeral <950> in FIG. 1A is a view when the substrate (601), the at least one insulator, and the first light emitting structure (520) are viewed in one direction. The first insulator (920) disposed on at least a portion of the first surface (5201) of the first light emitting structure (520) can include a plurality of first insulators. The plurality of first insulators can include a 1-1st insulator (9201), a 1-2nd insulator (9202), a 1-3rd insulator (9203), a 1-4th insulator (9204), a 1-5th insulator (9205), a 1-6th insulator (9206), a 1-7th insulator (9207), a 1-8th insulator (9208), and a 1-9th insulator (9209).
[0140] In an embodiment, the plurality of first insulators can be respectively disposed between a plurality of light sources to insulate the plurality of light sources included in the first light emitting structure (520). For example, the 1-1st insulator (9201) can be disposed between a first side surface (5203) of the first light emitting structure (520) and a 1-1st light source (521). The 1-2nd insulator (9202) can be disposed between the 1-1st light source (521) and a 1-2nd light source (523). The 1-3rd insulator (9203) can be disposed between the 1-2nd light source (523) and a 1-3rd light source (525). The 1-4th insulator (9204) can be disposed between the 1-3rd light source (525) and a 1-4th light source (527). The 1-5th insulator (9205) can be disposed between the 1-4th light source (527) and a 1-5th light source (529). The 1-6th insulator (9206) can be disposed between the 1-5th light source (529) and a 1-6th light source (531). The 1-7th insulator (9207) can be disposed between the 1-6th light source (531) and a 1-7th light source (533).

The 1-9th insulator (9209) can be disposed between the 1-8th light source (535) and a second side surface (5204) of the first light emitting structure (520).
[0141] In an embodiment, a first insulator (920) can be disposed on at least a portion of a first surface (5201) of a first light emitting structure (520), a second insulator (930) can be disposed on at least a portion of a first surface (5401) of a second light emitting structure (540), an nth insulator (940) can be disposed on at least a portion of a first surface (5701) of an nth light emitting structure (570), and then the first light emitting structure (520), the second light emitting structure (540), and the nth light emitting structure (570) can be electrically connected to the substrate (601) through an electrical connection structure such as a soldering member (615; 620; 625; 630; 635; 640).
[0142] Referring to Figure 9 , a configuration in which at least one insulator (e.g., a first insulator (920), a second insulator (930), and an nth insulator (940)) is disposed on a first surface (e.g., a first surface (5201) of a first light emitting structure (520), a first surface (5401) of a second light emitting structure (540), and a first surface (5701) of an nth light emitting structure (570)) of each light emitting structure has been described. However, the present disclosure is not limited thereto. For example, instead of the configuration in which at least one insulator (e.g., a first insulator (920), a second insulator (930), and an nth insulator (940)) is disposed on a first surface of each light emitting structure, at least one insulator can be disposed on a second surface (e.g., a second surface (5202) of a first light emitting structure (520), a second surface (5402) of a second light emitting structure (540), and a second surface (5702) of an nth light emitting structure (570)) of each light emitting structure.
[0143] As described above with reference to Figure 9 , the insulator (920; 930; 940) is disposed between a plurality of light sources included in each light emitting structure, so that the plurality of light sources can be insulated, a short circuit can be prevented, the light emitting structure can be firmly fixed to the substrate (601), and structural rigidity can be improved.
[0144] Figure 10 is a diagram for explaining a method of measuring a plurality of pieces of biological information of a user by using a plurality of light sources included in at least one light emitting structure according to an embodiment of the present disclosure.
[0145] Referring to Figure 6a , Figure 6b and Figure 7 to Figure 9 , a configuration in which at least one light emitting structure (e.g., a first light emitting structure (520) in a first biometric sensor (430)) of a first biometric sensor (e.g., a first biometric sensor (430)) is disposed on a first surface (e.g., a first surface (5201) of a first light emitting structure (520)) of a substrate (e.g., a substrate (601)) has been described. Figure 4 Figure 6a The first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570) are in an untilted state (e.g., perpendicular to the substrate). Figure 6a In the state of the substrate (601), at least one light-emitting structure is welded (e.g., by welding components (e.g., by...) Figure 6a and Figure 6b Welding of the first welded component (615), the second welded component (620), the third welded component (625), the fourth welded component (630), the fifth welded component (635) and / or the sixth welded component (640)) or wires (e.g., Figure 7 The first conductor (720), the second conductor (730), and / or the third conductor (740) are electrically connected to the substrate (601). However, this disclosure is not limited thereto.
[0146] For example, refer to Figure 10 When the first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570) of the first biometric sensor (430) are tilted at a specific angle, the first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570) can be electrically connected to the substrate (601) by welding (or wires).
[0147] In an embodiment, the electronic device (200) may include a rear surface panel (1010) (e.g., Figure 4 The rear panel (493) is in contact with the user's body (e.g., wrist) when the electronic device (200) is worn (or attached to) a part of the user's body (e.g., wrist).
[0148] In an embodiment, at least one of the first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570) can be electrically connected to the substrate (601) by welding (or wires) in a state where at least one light-emitting structure is tilted at a specific angle, such that light emitted from the plurality of light sources included in each light-emitting structure (e.g., the first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570)) reaches the light-irradiated area (1020) (e.g., the skin of a part of the user's body (e.g., the wrist)) (e.g., the light emitted from each light source is focused on the light-irradiated area (1020)).
[0149] In an embodiment, the specific angle at which at least one of the first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570) is tilted can be set based on the distance between each light-emitting structure and the light-irradiated area (1020).
[0150] However, the disclosure is not limited thereto. A specific angle at which at least one of the first light emitting structure (520), the second light emitting structure (540), and the nth light emitting structure (570) is inclined can be set in consideration of a distance between each light emitting structure and the light irradiation area (1020) and a configuration in which light is reflected by the back surface plate (1010) between each light emitting structure and the light irradiation area (1020).
[0151] For example, in consideration of a distance between the first light emitting structure (520) and the light irradiation area (1020) and a configuration in which light is reflected by the back surface plate (1010) between the first light emitting structure (520) and the light irradiation area (1020), the first light emitting structure (520) can be inclined at a specific angle (e.g., about 0.1 to 10 degrees), as at (1030). Also, in consideration of a distance between the second light emitting structure (540) and the light irradiation area (1020) and a configuration in which light is reflected by the back surface plate (1010) between the second light emitting structure (540) and the light irradiation area (1020), the second light emitting structure (540) can be maintained in a non-inclined state (e.g., a state perpendicular to the substrate (601)). Also, in consideration of a distance between the nth light emitting structure (570) and the light irradiation area (1020) and a configuration in which light is reflected by the back surface plate (1010) between the nth light emitting structure (570) and the light irradiation area (1020), the nth light emitting structure (570) can be inclined at a specific angle (e.g., about 0.1 to 10 degrees), as at (1040). That is, soldering (or wire) can be performed such that the first light emitting structure (520), the second light emitting structure (540), and the nth light emitting structure (570) can be electrically connected to the substrate (601) in a state in which the first light emitting structure (520) and the nth light emitting structure (570) are inclined at a specific angle (e.g., about 0.1 to 10 degrees) and the second light emitting structure (540) is not inclined at a specific angle (e.g., a state perpendicular to the substrate (601)).
[0152] In an embodiment, when an input (or a signal) for measuring a biological signal is detected, the light sources included in the first light emitting structure (520), the light sources included in the second light emitting structure (540), and the light sources included in the nth light emitting structure (570) can sequentially emit light of different wavelength ranges through different light paths. For example, the processor (120) can allow the plurality of light sources included in the first light emitting structure (520) tilted at (1030) at a certain angle (e.g., about 0.1 to 10 degrees) to sequentially emit light at the certain angle. The plurality of light sources included in the first light emitting structure (520) can sequentially emit light of different wavelength ranges through different light paths. The light sequentially emitted in different wavelength ranges through different light paths can reach the light irradiation area (1020). The processor (120) can allow the plurality of light sources included in the second light emitting structure (540) disposed at a certain angle in a state of being perpendicular to the substrate (601) to sequentially emit light at the certain angle in a state of being perpendicular to the substrate (601). The plurality of light sources included in the second light emitting structure (540) can sequentially emit light of different wavelength ranges through different light paths (e.g., different from the light paths of the plurality of light sources included in the first light emitting structure (520)). The light sequentially emitted in different wavelength ranges through different light paths can reach the light irradiation area (1020). The processor (120) can allow the plurality of light sources included in the nth light emitting structure (570) tilted at (1040) at a certain angle (e.g., about 0.1 to 10 degrees) to sequentially emit light at the certain angle. The plurality of light sources included in the nth light emitting structure (570) can sequentially emit light of different wavelength ranges through different light paths (e.g., different from the light paths of the plurality of light sources included in the first light emitting structure (520) and the second light emitting structure (540)). The light sequentially emitted in different wavelength ranges through different light paths can reach the light irradiation area (1020).
[0153] In an embodiment, the light sources included in the first light emitting structure (520), the light sources included in the second light emitting structure (540), and the light sources included in the nth light emitting structure (570) can sequentially emit light of different wavelength ranges through different light paths, thereby acquiring various biological information.

For example, the first light emitting structure (1121), the second light emitting structure (1123), the third light emitting structure (1125), and the fourth light emitting structure (1127) can be disposed in parallel on the substrate (601). The first monitoring circuit (1111) and the second monitoring circuit (1151) can be disposed at the periphery of the substrate (601) and in a direction orthogonal to the light emitting structures. The first monitoring circuit (1111) can identify the intensity (or amount) and wavelength range of light emitted in sequence from a plurality of light sources included in at least two of the first light emitting structure (1121), the second light emitting structure (1123), the third light emitting structure (1125), and the fourth light emitting structure (1127). The second monitoring circuit (1151) can identify the intensity (or amount) and wavelength range of light emitted in sequence from a plurality of light sources included in at least two of the remaining light emitting structures among the first light emitting structure (1121), the second light emitting structure (1123), the third light emitting structure (1125), and the fourth light emitting structure (1127).
[0160] Referring to reference numeral <1170> according to an embodiment, the first light emitting structure (1121), the second light emitting structure (1123), the third light emitting structure (1125), the fourth light emitting structure (1127), the first monitoring circuit (1111), the second monitoring circuit (1151), and the third monitoring circuit (1171) can be disposed on the substrate (601). For example, the first light emitting structure (1121), the second light emitting structure (1123), the third light emitting structure (1125), and the fourth light emitting structure (1127) can be disposed in parallel on the substrate (601). When the substrate (601) is viewed from the front, the first monitoring circuit (1111) can be disposed above the first light emitting structure (1121), the second monitoring circuit (1151) can be disposed between the second light emitting structure (1123) and the third light emitting structure (1125), and the third monitoring circuit (1171) can be disposed below the fourth light emitting structure (1127). In this case, the first monitoring circuit (1111) can identify the intensity (or amount) and wavelength range of light emitted in sequence from a plurality of light sources included in the first light emitting structure (1121). The second monitoring circuit (1151) can identify the intensity (or amount) and wavelength range of light emitted in sequence from a plurality of light sources included in the second light emitting structure (1123) and the third light emitting structure (1125). The third monitoring circuit (1171) can identify the intensity (or amount) and wavelength range of light emitted in sequence from a plurality of light sources included in the fourth light emitting structure (1127).
[0161] In an embodiment, at least one monitoring circuit (e.g., the first monitoring circuit (1111), the second monitoring circuit (1151), and / or the third monitoring circuit (1171)) can identify whether the plurality of light sources included in the light emitting structure (1121; 1123; 1125; 1127) emit light having a specified intensity (or power) and a specified wavelength range, and transmit the identified information (e.g., data related to whether the light is output at a specified intensity (or power) and a specified wavelength) to the processor (e.g., the processor (120) in Figure 1 ). The processor (120) can control the intensity (or amount) and the wavelength range of the emitted light by adjusting the gain based on the information transmitted through the at least one monitoring circuit (e.g., the first monitoring circuit (1111), the second monitoring circuit (1151), and / or the third monitoring circuit (1171)).
[0162] In an embodiment, the electronic device (200) can include a light detection circuit (not shown). The light detection circuit can receive light emitted from the plurality of light sources included in the light emitting structure (1121; 1123; 1125; 1127). For example, the light detection circuit can sequentially receive light sequentially emitted from the plurality of light sources. For example, the plurality of light sources having different wavelength ranges can sequentially emit light to the light irradiation area (e.g., the light irradiation area (1020) in Figure 10 ) under the control of the processor (120). The light detection circuit can sequentially receive light sequentially emitted from the plurality of light sources and reflected by the light irradiation area (1020). The processor (120) can measure (or acquire or identify) a plurality of pieces of biometric information based on the amount (or intensity) and the wavelength range of the light received by the light detection circuit.

[0165] In an embodiment, the first biometric sensor (1201) can include a sensor configured to measure (or acquire or identify) a plurality of pieces of biometric information by at least one light emitting structure (e.g., the light emitting structure (1121; 1123; 1125; 1127) in Figure 5 , Figure 6a , Figure 6b and Figure 7 to Figure 11 described above with reference to Figure 5The first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570) in the middle, and at least one monitoring circuit (e.g., Figure 11 The first monitoring circuit (1111), the second monitoring circuit (1151) and / or the third monitoring circuit (1171) and / or the light detection circuit (e.g., Figure 14 The first light detection circuit (1430) and the second light detection circuit (1435) are used to acquire (or receive) light. In an embodiment, the plurality of light sources included in at least one light-emitting structure may include laser diodes.

However, this disclosure is not limited thereto.
[0167] In this embodiment, the first biometric sensor (1201) and the second biometric sensor (1203) may be disposed on a substrate (e.g., Figure 6a The first biometric sensor (1201) and the second biometric sensor (1203) can be disposed on the same plane of the substrate (601).
[0168] In an embodiment, the electronic device (200) may include a rear surface panel (1010) (e.g., Figure 4 The rear panel (493) is in contact with the user's body (e.g., wrist) when the electronic device (200) is worn (or attached to) a part of the user's body (e.g., wrist).
[0169] In an embodiment, when an input (or signal) for measuring a biosignal is detected, the processor (e.g., Figure 1 The processor (120) in the first biometric sensor (1201) can be controlled to emit light (651; 653; 655) from at least one light-emitting structure (e.g., ) included in the first biometric sensor (1201). Figure 5 The first light-emitting structure (520), the second light-emitting structure (540), ... and the nth light-emitting structure (570) in the first biometric sensor (1201) emit light from multiple light sources. The light is emitted from at least one light-emitting structure (e.g., ...) included in the first biometric sensor (1201). Figure 5The light (651; 653; 655) emitted in sequence by the plurality of light sources in the first light emitting structure (520), the second light emitting structure (540), and the nth light emitting structure (570) in the first biological feature sensor (1201) can be acquired (or received) by the monitoring circuit (e.g., the first monitoring circuit (1410) and the second monitoring circuit (1415)) and / or the light detection circuit (e.g., the first light detection circuit (1430) and the second light detection circuit (1435)). The processor (120) can generate a spectrum for each wavelength range based on the light acquired (or received) by the monitoring circuit (e.g., the first monitoring circuit (1410) and the second monitoring circuit (1415)) and / or the light detection circuit (e.g., the first light detection circuit (1430) and the second light detection circuit (1435)). The processor (120) can measure (or acquire) at least one piece of first biological information based on the generated spectrum for each wavelength range.
[0170] In an embodiment, when an input (or a signal) for measuring a biological signal is detected, the processor (120) can control such that light (1215; 1245) is emitted from the light emitting sensor (1210; 1240) included in the second biological feature sensor (1203). The light (1215; 1245) emitted from the light emitting sensor (1210; 1240) of the second biological feature sensor (1203) can be reflected by the light irradiation area (1020) (e.g., the skin of a part (e.g., a wrist) of the user's body). The light receiving sensor (1205; 1235) can receive the light reflected from the light irradiation area (1020). The processor (120) can measure (or acquire) at least one piece of second biological information of the user based on the light received by the light receiving sensor (1205; 1235).
[0171] Reference Figure 12a The configuration in which the first biological feature sensor (1201) and the second biological feature sensor (1203) are disposed on the same plane of the substrate (601) has been described. However, the present disclosure is not limited thereto. In this regard, various embodiments will be described below with reference to Figure 12b
[0172] Figure 12b is a diagram illustrating a state in which a plurality of biological feature sensors are disposed according to an embodiment of the present disclosure.

[0174] Because the first biometric sensor (1201) and the second biometric sensor (1203) in the electronic device according to various embodiments are substantially the same as the first biometric sensor (1201) and the second biometric sensor (1203) described above with reference to FIGS. 1 to 12B, a detailed description thereof is replaced by the description made with reference to FIGS. 1 to 12B. Figure 12b Because the first biometric sensor (1201) and the second biometric sensor (1203) in the electronic device according to various embodiments are substantially the same as the first biometric sensor (1201) and the second biometric sensor (1203) described above with reference to FIGS. 1 to 12B, a detailed description thereof is replaced by the description made with reference to FIGS. 1 to 12B. Figure 12a Because the first biometric sensor (1201) and the second biometric sensor (1203) in the electronic device according to various embodiments are substantially the same as the first biometric sensor (1201) and the second biometric sensor (1203) described above with reference to FIGS. 1 to 12B, a detailed description thereof is replaced by the description made with reference to FIGS. 1 to 12B. Figure 12a Because the first biometric sensor (1201) and the second biometric sensor (1203) in the electronic device according to various embodiments are substantially the same as the first biometric sensor (1201) and the second biometric sensor (1203) described above with reference to FIGS. 1 to 12B, a detailed description thereof is replaced by the description made with reference to FIGS. 1 to 12B.
[0175] In an embodiment, the first biometric sensor (1201) and the second biometric sensor (1203) can be disposed on a substrate (e.g., the substrate (601) in FIGS. 1 to 12B). For example, the first biometric sensor (1201) and the second biometric sensor (1203) can be disposed on different planes of the substrate (601). For example, a recess can be formed in a partial area of the substrate (601), the first biometric sensor (1201) can be disposed in the formed recess, and the second biometric sensor (1203) can be disposed in another partial area of the substrate (601). Figure 6a As another example, the first biometric sensor (1201) and the second biometric sensor (1203) can be disposed on different substrates. For example, the first biometric sensor (1201) can be disposed on the substrate (601), and the second biometric sensor (1203) can be disposed on the printed circuit board (480) illustrated in FIG. 12B. In this case, a partial area of the printed circuit board (480) overlapping the first biometric sensor (1201) can be made of a material capable of transmitting light (e.g., infrared rays or visible light). However, the present disclosure is not limited thereto. The partial area of the printed circuit board (480) overlapping the first biometric sensor (1201) can have a hole formed such that light emitted from the first biometric sensor (1201) can reach the light irradiation area (1020).

[0177] The distance between the rear surface plate (1010) (e.g., the rear plate (493) in FIGS. 1 to 12B) and the second biometric sensor (1203) can be longer than the distance between the rear surface plate (1010) and the first biometric sensor (1201). For example, the plurality of light sources included in the second biometric sensor (1203) can include laser diodes. Laser diodes have straightness and are not easy to scatter light. Accordingly, the second biometric sensor (1203) can be disposed farther from the rear surface plate (1010) than the first biometric sensor (1201). Figure 12b Figure 4

For example, the processor (120) can control the driver (1405) to adjust a current to be supplied to the plurality of light sources based on an external temperature and / or a signal of the monitoring circuit (e.g., the first monitoring circuit (1410) and the second monitoring circuit (1415)).
[0190] In an embodiment, the driver (1405) can control operations of the plurality of light sources included in the first light emitting structure (520) having different wavelength ranges under the control of the processor (120). For example, the driver (1405) can turn on or off the plurality of light sources included in the first light emitting structure (520) under the control of the processor (120). For example, the driver (1405) can control to supply a current to the first light emitting structure (520) and allow the plurality of light sources to sequentially emit light of a corresponding wavelength range under the control of the processor (120). However, the disclosure is not limited thereto. The driver (1405) can modulate a current to obtain an additional signal-to-noise ratio (SNR) under the control of the processor (120).
[0191] In an embodiment, the amplifier (1420) can convert a current generated by the monitoring circuit (e.g., the first monitoring circuit (1410) and the second monitoring circuit (1415)) into a voltage and transmit the voltage to the ADC (1425). In this case, the amplifier (1420) can adjust a gain for converting the current into the voltage in consideration of a range and / or a signal strength of the ADC (1425). However, the disclosure is not limited thereto. The amplifier (1420) can adjust a bias so that the monitoring circuit (e.g., the first monitoring circuit (1410) and the second monitoring circuit (1415)) can operate in a designated range.
[0192] In an embodiment, the ADC (1425) can change the voltage received from the amplifier (1420) into a digital signal so that the processor (120) can recognize the digital signal.
[0193] In an embodiment, the processor (120) can sequentially emit light from a plurality of light sources having different wavelength ranges included in each light emitting structure, and measure at least a portion of light reflected by the back surface plate (1010) and / or the light irradiation area (1020) (e.g., skin of a part (e.g., a wrist) of a user's body). The processor (120) can generate a spectrum for each wavelength range based on an amount of light absorbed calculated from the reflected light according to each wavelength range.
[0194] For example, in a case where the 1-1 light source (521) of the first light emitting structure (520) emits light of a 1-1 wavelength range (e.g., λ 1,1 ), the monitoring circuit (e.g., the first monitoring circuit (1410) and the second monitoring circuit (1415)) can acquire (or receive) at least a portion of light (1451; 1453; 1455; 1457) reflected or scattered by the back surface plate (1010). Also, in a case where the 1-1 light source of the first light emitting structure (520) emits light of a 1-1 wavelength range (e.g., λ 1,1 ), the light detection circuit (e.g., the first light detection circuit (1430) and the second light detection circuit (1435)) can acquire (or receive) light (1461; 1463; 1465; 1467) absorbed and reflected by the light irradiation area (1020) (e.g., skin of a part (e.g., a wrist) of a user's body).

The processor (120) can generate a spectrum of each wavelength range (e.g., the 1st-1 wavelength range (e.g., λ 1,1 ) to the 1st-8 wavelength range (e.g., λ 1,8 )) based on the light acquired (or received) by the monitoring circuit (e.g., the first monitoring circuit (1410) and the second monitoring circuit (1415)) and the light acquired (or received) by the light detection circuit (e.g., the first light detection circuit (1430) and the second light detection circuit (1435)).
[0198] In embodiments, the processor (120) can allow the plurality of light sources included in the other light emitting structure (e.g., the second light emitting structure (540)) to emit light (653) in the 2nd-1 wavelength range (e.g., λ 2,1 ) to the 2nd-8 wavelength range (e.g., λ 2,8 ). In addition, the processor (120) can allow the plurality of light sources included in the other light emitting structure (e.g., the n-th light emitting structure (570)) to emit light (655) in the n-th-1 wavelength range (e.g., λ n,1 ) to the n-th-8 wavelength range (e.g., λ n,8 ).

The processor (120) may also allow light detection circuitry (e.g., a first light detection circuit (1430) and a second light detection circuit (1435)) to acquire (or receive) light emitted from multiple light sources included in the second light-emitting structure (540) and / or multiple light sources included in the nth light-emitting structure (570) and absorbed and reflected by the light-illuminating region (1020). The processor (120) can generate each wavelength range (e.g., the second-to-first wavelength range (e.g., λ) based on light acquired (or received) by monitoring circuits (e.g., first monitoring circuit (1410) and second monitoring circuit (1415)) and light acquired (or received) by light detection circuits (e.g., first light detection circuit (1430) and second light detection circuit (1435)). 2,1 ) to the 2nd-8th wavelength range (e.g., λ) 2,8 ) and the (n-1)th wavelength range (e.g., λ n,1 ) to the (n-8)th wavelength range (e.g., λ n,8 The spectrum of )).
[0200] In one embodiment, the processor (120) can measure at least one piece of biological information by analyzing the spectrum of each wavelength range. (Refer to the description below.) Figure 15 The configuration for generating spectra for each wavelength range according to the embodiment is described in detail.

[0202] refer to Figure 15 The x-axis represents the wavelength range (nanometers (nm)) (1505), and the y-axis represents the absorptivity (1510).
[0203] refer to Figure 15 Electronic devices (e.g.) Figure 1 Electronic device (101) or Figure 2 to Figure 4 The processor of the electronic device (200) in the device (e.g., Figure 1 The processor (120) in the light-emitting structure (e.g., Figure 6a The first light-emitting structure (520), the second light-emitting structure (540) ... and the nth light-emitting structure (570) emit light from multiple light sources with different wavelength ranges, and the light emitted by the rear surface plate (e.g., Figure 10the back surface panel (1010) and / or the light irradiation area (e.g. Figure 10 light (and / or scattered light) reflected by the light irradiation area (1020) (e.g., the skin of a part of the user's body (e.g., a wrist)).
[0204] For example, in a case where the 1-1 light source (521) of the light emitting structure (520) emits light of the 1-1 wavelength range (1515) (e.g., λ 1,1 , the monitoring circuit (e.g. Figure 14 the first monitoring circuit (1410) and the second monitoring circuit (1415) in the light emitting structure (520) can acquire (or receive) at least a part of the light (e.g., Figure 14 (1451; 1453; 1455; 1457) in the light emitting structure (520). In addition, in a case where the 1-1 light source (521) of the light emitting structure (520) emits light of the 1-1 wavelength range (1515) (e.g., λ 1,1 , the light detection circuit (e.g. Figure 14 the first light detection circuit (1430) and the second light detection circuit (1435) in the light emitting structure (520) can acquire (or receive) light (e.g., Figure 14 (1461; 1463; 1465; 1467). The description will be made based on the assumption that the amount (or intensity) of the light (1451; 1453; 1455; 1457) reflected or scattered by the back surface panel (1010) is defined as M 1,1 , and the amount of the light (e.g., Figure 14 (1461; 1463; 1465; 1467) absorbed and reflected by the light irradiation area (1020) (e.g., the skin of a part of the user's body (e.g., a wrist)) is defined as R 1,1 . In this case, the processor (120) can create the 1-1 point (1541) based on R 1,1 / M 1,1
[0205] As another example, in a case where the 1-2 light source (523) of the first light emitting structure (520) emits light of the 1-2 wavelength range (1520) (e.g., λ 1,2 , the monitoring circuit (e.g. Figure 14 The first monitoring circuit (1410) and the second monitoring circuit (1415) in the light detection circuit (1400) can acquire (or receive) at least a portion of the light reflected or scattered by the rear surface plate (1010). In addition, in a case where the 1-2 light source (523) of the first light emitting structure (520) emits light of the 1-2 wavelength range (1520), the light detection circuit (for example, Figure 14 The first light detection circuit (1430) and the second light detection circuit (1435) in the light detection circuit (1400) can acquire (or receive) light absorbed and reflected by the light irradiation region (1020) (for example, the skin of a part of the user's body (for example, a wrist)). The description will be made based on the assumption that the amount of acquired (or received) light reflected or scattered by the rear surface plate (1010) is defined as M 1,2 , and the amount of light absorbed and reflected by the light irradiation region (1020) (for example, the skin of a part of the user's body (for example, a wrist)) is defined as R 1,2 In this case, the processor (120) can create the 1-2 point (1543) based on R 1,2 / M 1,2
[0206] In a case where light of the n-1 wavelength range (1525) (for example, λ n,1 ) to the n-8 wavelength range (1530) (for example, λ n,8 ) is emitted from the n-1 light source to the n-8 light source of the n light emitting structure (570) in the above-described manner, the monitoring circuit (for example, Figure 14 The first monitoring circuit (1410) and the second monitoring circuit (1415) in the light detection circuit (1400) can acquire (or receive) at least a portion of the light reflected or scattered by the rear surface plate (1010). In addition, in a case where the 1-2 light source (523) of the first light emitting structure (520) emits light of the 1-2 wavelength range, the light detection circuit (for example, Figure 14 The first light detection circuit (1430) and the second light detection circuit (1435) in the light detection circuit (1400) can acquire (or receive) light absorbed and reflected by the light irradiation region (1020) (for example, the skin of a part of the user's body (for example, a wrist)). The processor (120) can create the n-1 point (1545) to the n-8 point (1547) based on the amount of acquired (or received) light reflected or scattered by the rear surface plate (1010) and the amount of light absorbed and reflected by the light irradiation region (1020) (for example, the skin of a part of the user's body (for example, a wrist)).
[0207] In an embodiment, the spectrum of each wavelength range can be generated by connecting (or correcting) the 1-1 point (1541), the 1-2 point (1543), …, and the n-1 point (1545) to the n-8 point (1547). The processor (120) can measure at least one piece of biological information by analyzing the generated spectrum of each wavelength range.
