[0031] The embodiments described below relate to the technical field of bioinformatics measurement devices (e.g., blood pressure measurement devices), and detailed descriptions of things known to those skilled in the art will be omitted.

[0032] Figure 1 This is a block diagram illustrating a bioinformatics measurement device according to an example embodiment.

[0033] Biometric information may include biological and medical information that can be obtained from the object (OBJ) to be measured, and may include, for example, blood pressure, blood glucose, body fat, blood oxygen saturation, vascular elasticity, blood flow rate, or arterial stiffness. The object may be a part of the human body from which biometric information can be easily measured (such as, for example, the area of ​​the wrist adjacent to the radial artery or the upper area of ​​the wrist through which capillary or venous blood flows, or a distal body part with high-density blood vessels (such as fingers, toes, etc.)).

[0034] Reference Figure 1The bioinformatics measurement device 1000 may include a light-emitting pixel array 100 for emitting light onto an object OBJ, a light-emitting pixel controller 200 for driving the light-emitting pixel array 100, a light-receiving pixel array 300 for detecting light returning after being scattered, reflected, or transmitted through the object OBJ, a light-receiving pixel controller 400 for driving the light-receiving pixel array 300, and a biosignal processor 500 for measuring bioinformatics from signals detected by the light-receiving pixel array 300.

[0035] The light-emitting pixel array 100 may be an array of light-emitting pixels that emit light onto the object OBJ, and may include a plurality of light-emitting pixels 111, 121, etc. arranged in a two-dimensional manner. The light-emitting pixel array 100 may include a plurality of light-emitting pixel rows 110, 120 and 130 containing a plurality of light-emitting pixels 111 to 116, 121 to 126, 131 to 136, etc. Figure 1 The diagram shows a light-emitting pixel array 100 comprising three rows of light-emitting pixels 110, 120, and 130 containing multiple light-emitting pixels 111, 121, etc. Figure 1 The first row of light-emitting pixels to the third row of light-emitting pixels 110, 120 and 130 may each include six light-emitting pixels 111, 121 and so on, and for example, the first row of light-emitting pixels 110 may include 1-1 light-emitting pixels 111 to 1-6 light-emitting pixels 116.

[0036] Each of the light-emitting pixels 111, 121, etc., may include a light-emitting element and a light-emitting pixel circuit for driving the light-emitting element. The light-emitting element included in each of the light-emitting pixels 111, 121, etc., may be a light source (such as a light-emitting diode (LED), a laser diode (LD), an organic light-emitting diode (OLED), etc.), and will be referred to below. Figure 2A Describe the structure of the light-emitting pixel circuit.

[0037] The light-emitting pixel array 100 may include light-emitting pixels 111, 121, etc., which emit two or more different wavelengths of light penetrating to different depths in the object OBJ. For example, the first light-emitting pixel 111, the third light-emitting pixel 113, and the fifth light-emitting pixel 115 included in the first light-emitting pixel row 110 may emit light of a first wavelength, and other pixels included in the first light-emitting pixel row 110 (i.e., the second light-emitting pixel 112, the fourth light-emitting pixel 114, and the sixth light-emitting pixel 116) may emit light of a second wavelength. The first wavelength of light may be long-wavelength light with a high penetration depth into the object OBJ (e.g., light in the infrared wavelength range (e.g., 750 nm to 2500 nm)). The second wavelength of light may be short-wavelength light with a smaller penetration depth into the object OBJ than the first wavelength of light (e.g., light in the green wavelength range (e.g., 500 nm to 565 nm)).

[0038] In addition to the structure shown above, the light-emitting pixel array 100 may also include various combinations of light-emitting pixels 111, 121, etc., and may be configured such that a row of light-emitting pixels 110, 120, or 130 includes light-emitting pixels emitting three or four different wavelengths. In another example, each pixel row may be configured to emit light of a different wavelength. In this case, the first row of light-emitting pixels 110 may emit infrared light, the second row of light-emitting pixels 120 may emit green light, and the third row of light-emitting pixels 130 may emit blue light.

[0039] The light-emitting pixel controller 200 can supply power to the light-emitting pixel array 100 and can generate and transmit signals (such as scan line signals, data line signals, and refresh signals) for driving the light-emitting pixel array 100. The light-emitting pixel controller 200 can independently control the on / off operation and light emission amount of each of the light-emitting pixels 111, 121, etc.

[0040] The light-receiving pixel array 300 is an array of light-receiving pixels that detect light returned from the object OBJ and generate electrical signals, and may include multiple light-receiving pixels 311, 312, etc. arranged in a two-dimensional manner. The light-receiving pixel array 300 may include multiple rows of light-receiving pixels 310, 320, and 330 containing multiple light-receiving pixels 311, 321, etc. Figure 1 An optical receiving pixel array 300 is shown, comprising three rows of optical receiving pixels 310, 320, and 330, including multiple optical receiving pixels 311, 321, etc. The first to third rows of optical receiving pixels 310, 320, and 330 may each include six optical receiving pixels 311 to 316, 321 to 326, 331 to 336, etc. For example, the first row of optical receiving pixels 310 may include 1-1 optical receiving pixels 311 to 1-6 optical receiving pixels 316.

[0041] Light receiving pixels 311, 321, etc., may each include a photoelectric conversion element for converting light into an electrical signal and a light receiving pixel circuit for driving the photoelectric conversion element. The photoelectric conversion element included in each of the light receiving pixels 311, 321, etc., can be implemented as a photodiode, phototransistor, photogate, pinned photodiode, etc. A color filter for selectively transmitting or removing light of a specific wavelength can be disposed on the upper part of each of the light receiving pixels 311, 321, etc. Reference will be made below. Figure 4 Describe the structure of the light-receiving pixel circuit.

[0042] One or more rows of light-receiving pixels 310, 320, and 330 may be arranged between rows of light-emitting pixels 110, 120, and 130. For example, Figure 1 As shown, the first light-receiving pixel row 310 can be disposed between the first light-emitting pixel row 110 and the second light-emitting pixel row 120. Although Figure 1 A row of light-receiving pixels is shown positioned between rows of light-emitting pixels 110, 120, and 130, but two or more rows of light-receiving pixels (e.g., two to two thousand rows of light-receiving pixels) may be positioned between rows of light-emitting pixels 110, 120, and 130.

[0043] also, Figure 1 An example is shown with one row of emitting pixels arranged between rows of light-receiving pixels 310, 320 and 330, but two or more rows of emitting pixels (e.g., two to two thousand) may be arranged between rows of light-receiving pixels 310, 320 and 330.

[0044] The light-receiving pixel controller 400 can supply power to the light-receiving pixel array 300 and can generate and transmit light-receiving pixel driving signals (such as timing signals, transmit signals TG, reset signals RG, selection signals SEL, etc.) for driving the light-receiving pixel array 300. The light-receiving pixel controller 400 can drive the light-receiving pixel array 300 using a rolling shutter method or a global shutter method. In the rolling shutter method, light-receiving pixel rows 310, 320, and 330 are exposed and read out sequentially, while in the global shutter method, light-receiving pixel rows 310, 320, and 330 are exposed and read out simultaneously.

[0045] The biosignal processor 500 can use data output from the light-receiving pixel array 300 to measure biological information. The output data from the light-receiving pixel array 300 received by the biosignal processor 500 can be data related to the intensity of light detected by light-receiving pixels 311, 321, etc., and the biosignal processor 500 can analyze / extract biological information by analyzing the received data.

[0046] The biosignal processor 500 may include components for processing light-sensing data from a conventional image sensor, such as a complementary metal-oxide-semiconductor (CMOS) image sensor. For example, the biosignal processor 500 may include a data output interface 510 that receives analog light-receiving pixel signals from light-receiving pixels 311, 321, etc., converts the received signals into digital signals, temporarily stores the digital signals, amplifies the digital signals, and outputs the amplified digital signals externally. Specifically, the data output interface 510 may include an analog-to-digital converter (ADC) that compares the amplitude of the correlated double-sampled analog signals from the light-receiving pixels 311, 321, etc., with the amplitude of a ramp signal to generate a comparison signal corresponding to the amplitude difference of each signal, and converts the analog signals into digital signals by counting the comparison signals. The data output interface 510 may include a memory for storing the digital signals and a buffer including an amplifier for sensing and amplifying the digital signals.

[0047] Furthermore, the biosignal processor 500 can generate timing signals and drive signals to enable the luminescent pixel array 100 and the light-receiving pixel array 300 to interact with each other, and send the generated timing signals and drive signals to the luminescent pixel controller 200 and the light-receiving pixel controller 400. For example, the biosignal processor 500 can generate timing signals based on a master clock signal received from a processor (e.g., a central processing unit (CPU) and / or a clock signal generated by a separate clock generator), and send the generated timing signals to the luminescent pixel controller 200 and the light-receiving pixel controller 400. The timing signals can be pixel clocks used as a reference for a series of operations performed in the bioinformatics measurement device 1000 (such as the luminescence operation of the luminescent pixel array 100, the photoelectric conversion operation of the light-receiving pixel array 300, the analog-to-digital conversion operation of the data output interface 510, etc.).

[0048] Figure 2A It is shown Figure 1 An example illustration of a light-emitting pixel with a 4T-2C structure. Figure 2B This is a diagram illustrating an example of a 2T-1C pixel driving circuit applied to a general display device.

[0049] Reference Figure 2A Each of the light-emitting pixels 111, 121, etc., may include a light-emitting element ED and pixel circuitry. The pixel circuitry may include a switching transistor TRs, a transmission transistor TRt, a refresh transistor TRr, a drive transistor TRd, a memory capacitor Cm, and a storage capacitor Cst.

[0050] The switching transistors TRs can be connected to the scan line SL and the data line DL, and send the data signal input through the data line DL to the memory according to the scan signal input through the scan line SL.

[0051] The memory capacitor Cm can be connected to the switching transistor TRs, the transmission transistor TRt, and the drive voltage line PL. The memory capacitor Cm can store, through the switching transistor TRs, a voltage Vcm corresponding to the difference between the voltage on the data line DL and the drive voltage VDD. The memory capacitor voltage Vcm can be a value corresponding to the data signal input through the data line DL.

[0052] The transfer transistor TRt can be connected to the drive voltage line PL and the storage capacitor Cst, and can provide a voltage corresponding to the storage capacitor voltage Vcm to the refresh transistor TRr.

[0053] The refresh transistor TRr can be connected to the refresh line RL, the transfer transistor TRt, and the storage capacitor Cst, and can supply the voltage transmitted from the transfer transistor TRt to the storage capacitor Cst according to the refresh signal input through the refresh line RL. As mentioned above, the voltage provided by the transfer transistor TRt is a value corresponding to the storage capacitor voltage Vcm, therefore the refresh transistor TRr can supply the storage capacitor voltage Vcm to the storage capacitor Cst.

[0054] The storage capacitor Cst can be connected to the refresh transistor TRr, the drive transistor TRd, and the drive voltage line PL, and can store a voltage Vcst corresponding to the difference between the voltage provided by the refresh transistor TRr and the drive voltage VDD. The voltage Vcst of the storage capacitor can be charged by the memory capacitor Cm. Since the voltage Vcst of the storage capacitor determines the amplitude of the voltage to be applied to the light-emitting element ED (i.e., the on / off operation of the light-emitting element and the amount of light emitted), the storage capacitor stores the light-emitting pixel signal.

[0055] The driving transistor TRd can be connected to the storage capacitor Cst and the driving voltage line PL, and can provide the driving current corresponding to the voltage stored in the storage capacitor Cst to the light-emitting element ED.

[0056] Figure 2A The difference between the light-emitting pixel driving circuit and the 2T-1C active matrix pixel driving circuit is that... Figure 2A The light-emitting pixel driving circuit includes a refresh line RL, a refresh transistor TRr, a transfer transistor TRt, and a memory capacitor Cm.

[0057] exist Figure 2B In the 2T-1C luminescent pixel circuit, the signal sent to the pixel via the data line DL is directly stored in the storage capacitor Cst through the switching transistor TRs, without passing through the memory capacitor Cm. Figure 2A The signal of the data line DL is not directly stored in the storage capacitor Cst, but is stored in the memory capacitor Cm, and is then sent to the storage capacitor Cst in response to the signal of the refresh line RL.

[0058] also, Figure 2B The light-emitting pixel circuit and Figure 2A The difference in the light-emitting pixel circuit is that the storage capacitor voltage Vcst is refreshed by the signal of the scan line SL, while Figure 2A The storage capacitor voltage Vcst in the light-emitting pixel circuit is refreshed by a signal on the refresh line RL, which is set independently of the scan line RL. Therefore, including Figure 2BThe light-emitting pixel rows in the light-emitting pixel array of the light-emitting pixel circuit, corresponding to the signals of scan lines SL, are sequentially refreshed, while including Figure 2A The light-emitting pixel circuit Figure 1 All luminous pixels 111, 121, etc., included in the luminous pixel array can be refreshed simultaneously. In other words, in Figure 1 In the luminous pixel array 100, luminous pixels 111, 121, etc. included in different rows of luminous pixels can be refreshed simultaneously using refresh lines RL.

[0059] Figure 3 It is used to describe Figure 1 A diagram illustrating the refresh operation of the luminescent pixel array.

[0060] Figure 3 Show Figure 1 The pixel circuits of four adjacent light-emitting pixels 111, 112, 121 and 122 among the light-emitting pixels. Figure 3 The light-emitting pixels 111, 112, 121, and 122 shown may include those referenced above. Figure 2A The 4T-2C structure is described.

[0061] Reference Figure 3 The first light-emitting pixel column 101 includes light-emitting pixels 111 (1-1) and 121 (2-1), which can share a first refresh line RL1. Similarly, the second light-emitting pixel column 102 includes light-emitting pixels 112 (1-2) and 122 (2-2), which can share a second refresh line RL2. The first refresh line RL1 and the second refresh line RL2 can be connected to a common refresh line GRL. That is, when the light-emitting pixel controller 200 applies a refresh signal through the common refresh line GRL, all light-emitting pixels 111, 112, 121, and 122 can be refreshed simultaneously.

[0062] Table 1 below shows how the voltages of the storage capacitor Cst and the memory capacitor Cm change via the refresh signal.

[0063] Table 1

[0064]

[0065] Refer to Table 1 for a description of the process before applying the refresh signal (t=0). Figure 3The states of the light-emitting pixels 111, 112, 121, and 122 are defined. The storage capacitor voltages Vcst11, Vcst12, Vcst21, and Vcst22 are V11t0, V12t0, V21t0, and V22t0, respectively. The storage capacitor voltages Vcm11, Vcm12, Vcm21, and Vcm22 are charged to V11t1, V12t1, V21t1, and V22t1, respectively. Each light-emitting element ED is driven by a current corresponding to each of the storage capacitor voltages Vcst11, Vcst12, Vcst21, and Vcst22.

[0066] When a refresh signal is applied, the refresh transistors TRr included in the light-emitting pixels 111, 112, 121, and 122 are simultaneously turned on (switched closed), causing the storage capacitor voltages Vcst11, Vcst12, Vcst21, and Vcst22 to be updated to the memory capacitor voltages Vcm11, Vcm12, Vcm21, and Vcm22, respectively. For example, the current light-emitting pixel signal stored in the storage capacitor Cst can be changed to the next light-emitting pixel signal stored in the memory capacitor Cm. That is, the storage capacitor voltages Vcst11, Vcst12, Vcst21, and Vcst22 are changed from V11t0, V12t0, V21t0, and V22t0 to V11t1, V12t1, V21t1, and V22t1, which are the memory capacitor voltages Vcm11, Vcm12, Vcm21, and Vcm22, respectively.

[0067] After the refresh operation is completed, the refresh signal can be blocked to turn off the refresh transistor TRr (switch off), and the memory capacitor voltages Vcm11, Vcm12, Vcm21, and Vcm22 can be updated. For each pixel row, the memory capacitor voltages Vcm11, Vcm12, Vcm21, and Vcm22 can be updated sequentially via data line DL1 and scan line SL1 (e.g., sequential refresh or sequential update). Referring to Table 1, the memory capacitor voltages Vcm11, Vcm12, Vcm21, and Vcm22 can be updated from V11t1, V12t1, V21t1, and V22t1 to V11t2, V12t2, V21t2, and V22t2, respectively. While the storage capacitor voltages Vcm11, Vcm12, Vcm21, and Vcm22 are updated, the storage capacitor voltages Vcst11, Vcst12, Vcst21, and Vcst22 may remain unchanged, and each light-emitting element ED may be driven by a current corresponding to each storage capacitor voltage Vcst11, Vcst12, Vcst21, and Vcst22 (i.e., V11t1, V12t1, V21t1, and V22t1).

[0068] Subsequently, when the refresh signal is applied again, the storage capacitor voltages Vcst11, Vcst12, Vcst21, and Vcst22 can be updated from V11t1, V12t1, V21t1, and V22t1 to V11t2, V12t2, V21t2, and V22t2, respectively, and the simultaneous update of the storage capacitor Cst and the sequential update of the memory capacitor Cm can be repeated.

[0069] In summary, since the storage capacitor Cst stores the current light-emitting pixel signal applied to the light-emitting element ED, the storage capacitor voltage Vcst can be referred to as the nth light-emitting pixel signal, and since the memory capacitor Cm stores the next light-emitting pixel signal, the memory capacitor voltage Vcm can be referred to as the (n+1)th light-emitting pixel signal, where n can be a positive integer.

[0070] Figure 4 Show Figure 1 An example of a light-receiving pixel with a 4T structure.

[0071] Reference Figure 4 Each of the light-receiving pixels 311, 321, etc., may include a photodiode PD and pixel circuitry. Pixel circuitry may include a floating diffuser FD, a transmission transistor TX, a reset transistor RX, a drive transistor DX, and a selection transistor SX.

[0072] The floating diffuser FD is the connection between the transfer transistor TX, the reset transistor RX, and the drive transistor DX, and can be the part that accumulates the charge converted by the photodiode PD and converts the charge into voltage. The transfer transistor TX can be turned on to transfer the charge converted by the photodiode PD to the floating diffuser FD. The reset transistor RX is turned on to make the voltage of the floating diffuser FD equal to the power supply voltage VDD, and to remove the charge accumulated in the floating diffuser FD. The drive transistor DX can amplify the signal (i.e., voltage) caused by the charge accumulated in the floating diffuser FD. The select transistor SX can be turned on to output the voltage (i.e., the light receiving pixel signal) amplified by the drive transistor DX (e.g., via node PN) to the column line COL. Among the signals used to control the on / off state of transistors TX, RX, and SX, the signal used to control the transfer transistor TX is called the transfer signal TG, the signal used to control the reset transistor RX is called the reset signal RG, and the signal used to control the select transistor SX is called the select signal SEL.

[0073] When operating the light-receiving pixel array 300 using the rolling shutter method, it can be used Figure 4The light-receiving pixel circuit is described, and different structures of light-receiving pixel circuits can be applied when the light-receiving pixel array 300 is intended to be operated via a global shutter method. Since various structures of light-receiving pixel circuits driven by the global shutter method are known, their detailed descriptions are omitted here.

[0074] Figure 5 This illustrates a combined pixel circuit where light-emitting pixels and light-receiving pixels are combined.

[0075] Figure 5 Show Figure 1 A pixel circuit is formed by combining a 1-1 light-emitting pixel 111 and a 1-1 light-receiving pixel 311 adjacent to the 1-1 light-emitting pixel 111. The 1-1 light-emitting pixel 111 may include... Figure 2A The pixel circuit, and the 1-1 light receiving pixel 311 may include Figure 4 Pixel circuit.

[0076] In one embodiment, at least one of the light-emitting pixels and at least one of the light-receiving pixels may share a driving voltage line. Figure 5 The 1-1 light-emitting pixel 111 and the 1-1 light-receiving pixel 311 can share the driving voltage line PL. For example, the driving transistor TRd of the 1-1 light-emitting pixel 111 and the reset transistor RX of the 1-1 light-receiving pixel 311 can be connected to the same driving voltage line PL.

[0077] Figure 1 The bioinformatics measurement device 1000 has the same number of light-emitting pixels 111, 112, etc. as the number of light-receiving pixels 311, 312, etc., but the number of light-emitting pixels 111, 112, etc. may be different from the number of light-receiving pixels 311, 312, etc. For example, the number of light-receiving pixels 311, 312, etc. may be greater than the number of light-emitting pixels 111, 112, etc.

[0079] In the following text, reference will be made to Figures 6A to 9 Description of use Figure 1 Examples of methods for measuring various types of biological information, including photoplethysmography (PPG) signals and blood pressure, using the Bioinformatics Measurement Device 1000.

[0080] Figure 6A This is a diagram showing a pixel array including infrared emitting pixels and green emitting pixels. Figure 6B This is a diagram showing the state in which some infrared emitting pixels are turned on. Figure 6C It is an illustration showing the state of some green glowing pixels being turned on, and Figure 6D This is a diagram showing the state in which some green emitting pixels and some infrared emitting pixels are turned on.

[0081] Figure 6A Show Figure 1 The bioinformatics measurement device 1000 includes an example of light-emitting pixels that emit two different wavelengths of light, wherein the light-emitting pixel controller 200, the light-receiving pixel controller 400, and the biosignal processor 500 are omitted. The two different wavelengths can be, for example, infrared (IR) and green light (G). The infrared and green light-emitting pixels can be arranged in various ways. For example, as... Figure 6A As shown, infrared emitting pixels and green emitting pixels can be arranged alternately. Specifically, Figure 6A The bioinformatics measurement device 1000a may include infrared emitting pixels 111, 121, 131, etc. arranged in the first emitting pixel column 101, the third emitting pixel column 103 and the fifth emitting pixel column 105, and green emitting pixels 112, 122, 132, etc. arranged in the second emitting pixel column 102, the fourth emitting pixel column 104 and the sixth emitting pixel column 106.

[0082] Figure 6A The light-emitting pixel controller 200 can independently control each of the light-emitting pixels 111, 112, etc., and can turn all light-emitting pixels 111, 112, etc. on or off, or selectively turn on one or some light-emitting pixels as needed. For example, the light-emitting pixel controller 200 can... Figure 6B The diagram shows that only four infrared emitting pixels 111, 113, 121, and 123 among the emitting pixels 111, 112, etc., are selectively activated, or as shown in the diagram. Figure 6C The diagram shows that only four green luminous pixels 112, 114, 122, and 124 are selectively turned on.

[0083] The location of the light-emitting pixels to be turned on can be determined by considering the part of the object OBJ (such as fingers, wrists, etc.), the position of the object OBJ in contact with the bioinformatics measurement device 1000a, and the type of bioinformatics (such as blood pressure, body fat, etc.).

[0084] like Figure 6BAs shown, when infrared emitting pixels 111, 113, 121, and 123 are turned on to emit infrared light to the object OBJ, the infrared light scattered, reflected, or transmitted through the object OBJ can be sampled in the light receiving pixel array 300. Optionally, as Figure 6C As shown, when green emitting pixels 112, 114, 122 and 124 are turned on to emit green light to object OBJ, the green light returned from object OBJ can be sampled in light receiving pixel array 300.

[0085] because Figure 6A The bioinformatics measurement device 1000a includes a memory capacitor Cm and a refresh line RL, so that the light-emitting pixel signals applied to all light-emitting pixels 111, 112, etc., can be updated simultaneously. For example, Figure 6A The state of the light-emitting pixel array 100 can be obtained from Figure 6B The four infrared emitting pixels 111, 113, 121 and 123 are switched to the on state. Figure 6C The four green luminous pixels 112, 114, 122, and 124 are in the "on" state. If... Figure 6A The luminescent pixels 111, 112, etc. have such Figure 2B In the traditional 2T-1C structure shown, the luminous pixel signal is not updated simultaneously for all luminous pixels 111, 112, etc., but rather sequentially for each of the luminous pixel rows 110, 120, and 130 with a time difference. Therefore, it is possible for a situation like this to occur... Figure 6D The diagram shows the stage where infrared and green light are emitted simultaneously. In other words, it refers to the stage where the state of the light-emitting pixel array 100 is changed from... Figure 6B The state shown has switched to Figure 6C In the processing of the state shown, after the pixel signal of the first emitting pixel row 110 is updated and before the pixel signal of the second emitting pixel row 120 is updated, the emitting pixel array 100 may experience a state of simultaneously emitting infrared light and green light. When the emitting pixel array 100 emits light of two or more wavelengths simultaneously, the signal sampled by the light receiving pixel array 300 is usually a noisy signal that is difficult to use for biosignal analysis, so it is desirable that the emitting pixel array 100 does not emit light of two or more wavelengths simultaneously. As described above, since Figure 6A The light-emitting pixel array 100 includes a memory capacitor Cm and a refresh line RL, so that it will not undesirably emit two or more wavelengths of light at the same time, and the light-receiving pixel array 300 can continuously sample the effective signal.

[0086] Depend on Figure 6AThe bioinformatics measured by the bioinformatics measurement device can be PPG signals. PPG signals are signals obtained by emitting light of a specific wavelength into the human body and detecting the light's response, and can be signals indicating the ripple component generated due to heartbeats. The biosignal processor 500 can obtain PPG signals of infrared and green light using data sampled by the light-receiving pixel array 300.

[0087] Figure 7A An example of the first PPG signal PPG1 of infrared light obtained from the light-receiving pixel array 300 is shown. Figure 7B An example of the second PPG signal PPG2, which is green light, is shown.

[0088] Reference Figure 7A and Figure 7B The signals IR1, G1, etc., that constitute the first PPG signal PPG1 and the second PPG signal PPG2 can be corresponding to alternating repetitions such as Figure 6B The on / off states of the infrared emitting pixels 111, 113, 121, and 123 shown are as follows: Figure 6C The signals are sampled based on the on-state of the green emitting pixels 112, 114, 122, and 124 shown. For example, Figure 7A IR1 corresponds to the situation where the infrared emitting pixel is turned on. Figure 6B The first infrared signal sampled in the state, and IR6 can correspond to the state when the infrared emitting pixel is turned on. Figure 6B The sixth infrared signal sampled under the given condition. Similarly, Figure 7B G1 corresponds to the green emitting pixel being turned on. Figure 6C The first green light signal sampled in the state, and G6 can correspond to the state when the green light-emitting pixel is turned on. Figure 6C The sixth green light signal is sampled under the condition of [condition]. The infrared light signal and the green light signal can be sampled alternately (e.g., the first infrared light signal IR1 is sampled, followed by the first green light signal G1).

[0089] The light-receiving pixel signals sampled by the light-receiving pixel array 300 may include light-receiving pixel signals from multiple light-receiving pixels 311, 312, etc., and the biosignal processor 500 can obtain a PPG signal by processing the light-receiving pixel signals in various ways. For example, the PPG signal can be obtained by averaging the light-receiving pixel signals sampled by all light-receiving pixels 311, 312, etc., by averaging the light-receiving pixel signals sampled by a specific row of light-receiving pixels (e.g., the second row of light-receiving pixels 320), or by using only the signal sampled by light-receiving pixels located at a specific position (e.g., 3-3 light-receiving pixels 333).

[0090] Figure 8It is a diagram used to describe the principle of generating the unit waveform that constitutes the PPG signal. Figure 9 This is a diagram showing a unit waveform P that constitutes a PPG signal divided into multiple component waveforms.

[0091] Reference Figure 8 and Figure 9 The unit waveform P can be composed of a propagating wave P1 originating from the heart and heading towards a distal blood vessel bifurcation (such as the iliac artery) in the body, and reflected waves P2 and P3 returning from the distal or bifurcation. Specifically, the component waveforms P1, P2, and P3 may include the propagating wave P1 caused by the contraction of the heart, a first reflected wave P2 mainly reflected from the renal artery, and a second reflected wave P3 mainly reflected from the iliac artery. The amplitude of the propagating wave P1 is highly correlated with the heart's motion, and the amplitudes of the reflected waves P2 and P3 are highly correlated with the characteristics of the blood vessels. In this way, the unit waveform P of the PPG signal is divided into component waveforms P1, P2, and P3, and blood pressure can be measured by analyzing the intensity and duration of each of the component waveforms P1, P2, and P3, the intervals between component waveforms P1, P2, and P3, the ratio of intensities, etc. For example, blood pressure can be measured by analyzing the time interval between the peak points of the propagating wave P1 and the reflected waves P2 and P3 and / or the ratio of the maximum intensity of the peak points. Specifically, it can be measured by... Figure 7A The first PPG signal PPG1 and Figure 7B The second PPG signal, PPG2, is divided into component waveforms P1, P2, and P3 for analysis. Figure 7A The first PPG signal PPG1 and Figure 7B The second PPG signal, PPG2, can be used to average the values ​​obtained from the analysis to measure blood pressure, or based on... Figure 7B The second PPG signal, PPG2, can be used from... Figure 7A The information obtained from the first PPG signal PPG1 is used to correct the value obtained by analyzing the second PPG signal PPG2, thereby improving the accuracy of blood pressure measurement.

[0092] exist Figure 6A In the embodiments described, a method for measuring PPG signals or blood pressure using green and infrared wavelengths of light has been described as an example. However, Figure 1 The bioinformatics measurement device 1000 can use light of other wavelengths (such as blue light) and can be used to measure other bioinformatics (such as blood glucose, body fat, blood oxygen saturation, vascular elasticity, blood flow rate and arterial stiffness) in addition to blood pressure.
