With the continuous improvement of material life, people are more and more concerned about their own health. In order to facilitate users to understand their own health conditions, many electronic devices are equipped with health sensors to allow the users to better monitor their own health conditions.
In the related art, the health sensor is separately arranged outside the touch and display module (also called a touch screen) of the electronic device. Taking the smart phone illustrated in
In addition to the health sensor, in order to ensure the safety of the device, in the related arts, under-screen fingerprint sensors may be regularly distributed below the touch and display module to form a fingerprint recognition region 13 as illustrated in
In view of this, the present disclosure proposes an optical fingerprint module, integrating the health sensor and the fingerprint sensor into the same module, thereby avoiding the problem of occupying the layout space by arranging the health sensor.

The signal processing unit 22 is connected to the light sensing unit and is configured to process the light signal(s) collected by the light sensing unit to generate the fingerprint signal(s) and/or the health signal(s).
The control unit 23 is connected to the signal processing unit and is configured to generate fingerprint information for fingerprint recognition based on the fingerprint signal(s) output by the signal processing unit and generate health parameter information based on the health signal(s) output by the signal processing unit.
In the present disclosure, both the light sensing unit 21 and the signal processing unit 22 may have various structures, as long as the operation of collecting the light signals and processing the light signals can be realized, which are not limited in the present disclosure.
In some embodiments, the light sensing unit 21 may include a fingerprint sensor 211 and a health sensor 212 as illustrated in
Since in practical applications, the health testing can be performed by red light or green light, the health sensor may include a red light sensor 2121 and/or a green light sensor 2122. The red light sensor 2121 is configured to collect red light for the health testing. The green light sensor 2122 is configured to collect green light for the health testing. Correspondingly, the health signal processing circuitry 222 may include a red light signal processing circuitry 2221 and/or a green light signal processing circuitry 2222. The red light signal processing circuitry 2221 is connected to the red light sensor 2121 and is configured to process the red light collected by the red light sensor 2121 to obtain the red light signal. The green light signal processing circuitry 2222 is connected to the green light sensor 2122 and is configured to process the green light collected by the green light sensor 2122 to obtain the green light signal. Correspondingly, the control unit 23 is connected to the fingerprint signal processing circuitry 221 and is configured to generate the fingerprint information for the fingerprint recognition based on the fingerprint signal output by the fingerprint signal processing circuitry 221. The control unit is also connected to the red light signal processing circuitry 2221 and/or the green light signal processing circuitry 2222 and is configured to generate the health parameter information based on the red light signal output by the red light signal processing circuitry 2221 and/or generate the health parameter information based on the green light signal output by the green light signal processing circuitry 2222. Logical diagrams are illustrated as
In some embodiments, the fingerprint sensor 211 may be reused as the red light sensor 2121 and/or the green light sensor 2122 as described above. That is, the fingerprint sensor 211 may be also functioned as the red light sensor 2121 and/or the green light sensor 2122. In some embodiments, the light sensing unit 21 may include only the fingerprint sensor 211, and the signal processing unit may include both the fingerprint signal processing circuitry 221 and the red light signal processing circuitry 2221, both the fingerprint signal processing circuitry 221 and the green light signal processing circuitry 2222, or all of the fingerprint signal processing circuitry 221, the red light signal processing circuitry 2221 and the green light signal processing circuitry 2222. Correspondingly, the optical fingerprint module may further include a first circuit gating switch 241. The logical diagrams of the above three cases are illustrated as

In some embodiments, when the logical diagram is illustrated as
In some embodiments, the fingerprint sensor is reused as (or also functioned as) a red light sensor and/or a green light sensor. Therefore, there is no need to additionally arrange a health sensor in the electronic device having the optical fingerprint module, thereby solving a problem that the ratio of the area of the screen to the area of the front panel of the electronic device is reduced by separately arranging the health sensor, reducing the number of sensors to be deployed, and reducing hardware costs.
In some embodiments, two fingerprint sensors can be reused respectively as the red light sensor 2121 and the green light sensor 2122. In this case, the light sensing unit 21 may include a first fingerprint sensor 2111 and a second fingerprint sensor 2112. The signal processing unit 22 may include a first fingerprint signal processing circuitry 2211, a red light signal processing circuitry 2221, a second fingerprint signal processing circuitry 2212 and a green light signal processing circuitry 2222. Correspondingly, a second circuit gating switch 242 and a third circuit gating switch 243 may be also included. Details are illustrated in
In the above embodiments of collecting the red light signals and the green light signals, the red light signal and the green light signal may be separately obtained for the health testing, and the red light signal or the green light signal which has a higher stability can be further used as the health signal to generate the health parameter information. It can be understood that, the red light and the green light may be interfered differently in different environments, which will affect the results of the health testing. It can be seen that with the method, selection may be performed on the red light signal and the green light signal to determine the a signal that is less interfered for the health testing, thereby improving the accuracy of the health testing.
The health testing may be made usually by sending a beam of light to the human body and evaluating the health of the human body based on changes in the returned beam of light. Therefore, the optical fingerprint module may also include a health signal emitting end. For example, the optical fingerprint module may include a red light emitting end and/or a green light emitting end. The red light emitting end is configured to emit the red light for the health testing, and the green light emitting end is configured to emit the green light for the health testing.
The light signals collected by the present disclosure for the health testing may be monochromatic light, such as the red light and the green light as described above, and the health sensor may be a red light sensor or a green light sensor accordingly. In addition to monochromatic light, the light signals can also be infrared light, and the health sensor can be an infrared sensor correspondingly. Certainly, when the health sensor is an infrared sensor, since the fingerprint sensor is configured to collect visible light, the fingerprint sensor cannot be reused as a health sensor.
The health parameter information obtained by the optical fingerprint module of the present disclosure may include any of the following: heart rate, blood oxygen and blood pressure. Certainly, the above is only an example and illustrative. It should be understood that any parameter that can reflect the state of health can be used as the health parameter information of the present disclosure. The specific health parameter information obtained is related to the processing method of the health signal, which is not limited in the present disclosure.
The control unit in the present disclosure may be an MCU (Microcontroller Unit), a DSP (digital signal processor), or a CPU (central processing unit). Certainly, the above is only an example and illustrative. It should be understood that the hardware that can generate the health parameter information based on the health signal and can generate the fingerprint information for the fingerprint recognition based on the fingerprint signal can be used as the aforementioned control unit, which is not limited in the present disclosure
It can be seen from the above technical solutions that the optical fingerprint module according to embodiments of the present disclosure has both the health testing function and the fingerprint recognition function. Therefore, when this optical fingerprint module is integrated to an electronic device, there is no need to arrange a separate health sensor, thereby solving the problem existing in the related arts that the ratio of the area of the screen to the area of the front panel of the electronic device is reduced or the mechanical strength of the backplane of the electronic device is reduced by separately arranging the health sensor.
In addition, with the above-mentioned optical fingerprint module, since there is no need to arrange the health sensor separately, the space of the main circuit board of electronic device that is occupied by the health sensor may be reduced, such that developers can flexibly arrange various components at desired positions on the main circuit board, and development difficulty may be reduced.
Further, the health sensor according to the present disclosure can include both the red light sensor and the green light sensor. In this case, a signal that is less interfered may be selected from the signal collected by the red light sensor and the signal collected by the green light sensor can be selected to generate the health parameter information, thereby improving the accuracy of the health testing.
A sensing side of the touch layer 102 faces towards the glass cover layer 101.
A light-emitting side of the display layer 103 faces towards a non-sensing side of the touch layer 102.
The health testing and fingerprint recognition layer 104 includes the optical fingerprint module as described above, and a light-incoming side of the health testing and fingerprint recognition layer 104 faces towards the non-light-emitting side of the display layer 103.
The glass cover layer 101 may be made of a transparent glass material for protecting the touch and display module. The sensing side of the touch layer 102 can generate a touch signal based on a user's touch position. The method for generating the touch signal can be a sensing method of a capacitive screen or a sensing method of a resistive screen, which is not limited herein. The display layer 103 is also called a light-emitting layer and can display a corresponding image based on a control signal. The light sensing unit of the optical fingerprint module may be arranged on the light-incoming side of the health testing and fingerprint recognition layer 104 to collect the light signals.
It can be seen from the above touch display module that the health testing and fingerprint recognition layer of the touch and display module includes the optical fingerprint module described above. It can be seen that the processes of the health testing and fingerprint recognition are both performed by the touch and display module, such that the electronic device using the touch and display module does not need to arrange a separate health sensor. Compared to the electronic device that has a separately arranged health sensor outside the touch and display module, the mechanical strength of the backplane of the electronic device may be not affected and the ratio of the area of the screen to the area of the front panel may be higher in the present disclosure.
In some embodiments, the user can touch the fingerprint recognition region 113 with a finger to trigger the electronic device to perform the fingerprint recognition operation.
In actual operations, in order to accurately detect the user's fingerprints, several fingerprint sensors may be regularly distributed in the optical fingerprint module 112. In one case, at least one of the fingerprint sensors can be used as the health sensor of the optical fingerprint module. In this case, the fingerprint sensor may be reused as a health sensor, that is, the fingerprint sensor is also functioned as the health sensor and is configured to perform the fingerprint recognition and the health testing, thereby reducing the number of sensors to be deployed. In another case, a health sensor can be arranged near at least one fingerprint sensor. In this case, compared to the layout in the related arts, the position of the health sensor moves from outside the touch and display module to the fingerprint recognition region of the touch and display module, thereby avoiding separately arranging a health sensor.
In the electronic device according to embodiments of the present disclosure, the optical fingerprint module described above is assembled in the fingerprint recognition region. It can be seen that both the fingerprint sensor and the health sensor are arranged in the touch and display module, which solves the problem that the ratio of the area of the screen to the area of the front panel of the electronic device is reduced and the mechanical strength of the backplane of the electronic device is reduced due to the separately arranged health sensor.
At block 1202, a predefined health testing condition and a predefined fingerprint recognition condition are determined.
In some embodiments, after the light signals are collected by the light sensing unit in the optical fingerprint module, it can be determined whether to perform the health monitoring or the fingerprint recognition to collect corresponding light signals by the light sensing unit, based on the predefined health testing condition and the predefined fingerprint recognition condition.
At block 1204A, when the health testing condition is met, the light signals for the health testing collected by the light sensing unit is input to the signal processing unit in the optical fingerprint module, to generate the health parameter information based on the health signal output by the signal processing unit.
At block 1204B, when the fingerprint recognition condition is met, the light signals for the fingerprint recognition collected by the light sensing unit is input to the signal processing unit in the optical fingerprint module, to generate the fingerprint information for the fingerprint recognition based on the fingerprint signal output by the signal processing unit.
In practical applications, when the user's finger touches the fingerprint recognition region, the fingerprint recognition is usually performed to perform operations such as unlocking and payment. Therefore, it can be determined whether the fingerprint recognition is required by determining whether the fingerprint recognition region formed by the touch and display module of the electronic device detects a touch event or not. In this case, when a touch event that occurs in the fingerprint recognition region is detected, it is determined that the fingerprint recognition condition is met.
However, in actual situations, it is inevitable that there will be false touches. Therefore, on the premise of the aforementioned fingerprint recognition condition, that is, in the case that the touch event occurring in the fingerprint recognition region is detected, it can be further determined whether a pressing force corresponding to the touch event is not less than a preset pressure threshold. In the case that the pressing force is not less than the preset pressure threshold, it is determined that the fingerprint recognition condition is satisfied.
It should be understood that when a user desires to perform the health testing, the user usually launches an application related to the health testing in the electronic device, and activate the corresponding health testing function of the application. Therefore, in the present disclosure, a function of realizing the health testing may be set as a preset function and it may be determined whether the preset function of the electronic device is in an on state during the operation of the electronic device. In response to detecting that the preset function is in the on state, it is determined that the health detection condition is satisfied.
In practical applications, after the light used for health detection is collected, different software processing methods are adopted for the light to obtain different health parameter information. For example, the heart rate, blood oxygen, blood pressure and other parameters of the subject can be obtained by processing and analyzing the collected light.
It can be seen from the above technical solutions that, through the electronic device equipped with the optical fingerprint module, the light signals used to generate the health signal and the fingerprint signal are collected by the sensor arranged in the touch and display module, thereby solving the problem existing in the related arts that the ratio of the area of the screen to the area of the front panel of the electronic device is reduced and the mechanical strength of the backplane of the electronic device is affected by separately arranging the health sensor.
Further, in embodiments of the present disclosure, by determining whether the fingerprint recognition region is touched, it may be determined whether the fingerprint recognition is currently required. It should be understood that touching the fingerprint recognition region by the user means that there are unlocking and payment requirements, and fingerprint recognition is required. In the present disclosure, whether the preset function is in the on state is also used as the health detection condition. It should be understood that when the user activates the preset function for realizing the health testing, it is obviously that there is a need for the health testing. Thus, the technical solutions according to the present disclosure can perform the health testing or the fingerprint recognition based on the actual needs of the user, thereby improving user experience.
At block 1302, the red light for the health testing is collected by the light sensing unit in the optical fingerprint module, and the red light collected by the light sensing unit is inputted into the red light signal processing circuitry in the optical fingerprint module, such that the red light signal processing circuitry processes the red light to obtain the red light signal.
At step 1304, the green light for the health testing is collected by the light sensing unit in the optical fingerprint module, and the green light collected by the light sensing unit is input into the green light signal processing circuitry in the optical fingerprint module, such that the green light signal processing circuitry processes the green light to obtain the green light signal.
It should be understood that since the light may be interfered by many factors during the propagation process, the light will continuously change during the propagation process. In addition, there are certain differences in interfering different lights in different environments. That is, the stabilities of different lights are different in different environments. For example, when the human body is sweating, the sweat is easier to absorb the green light than the red light. As a result, the red light is more stable when the human body is sweating, and health testing is more accurate based on the red light. In view of this, in embodiments, the red light and the green light are collected by the optical fingerprint module, and the stability of the red light signal obtained by processing the red light is compared with the stability of the green light signal obtained by processing the green light to select the a signal having the higher stability as the health signal to generate the health parameter information.
In addition, normally, since the green light is better absorbed by the human body, changes in the human body may be easier detected based on the green light, and the health testing based on the green light may be more accurate. Therefore, in some embodiments, if the stability of the red light signal obtained by processing the red light is close to that of the green light signal obtained by processing the green light, the health testing is performed based on the green light signal obtained by processing the green light.
In some embodiments, the optical fingerprint module provided in the electronic device requires the functions of collecting the red light and the green light. Therefore, the optical fingerprint module according to the embodiments may be an optical fingerprint module being capable of collecting the red light and the green light as described above.
At block 1306, the stability of the red light signal is compared with the stability of the green light signal by the control unit in the optical fingerprint module, such that the control unit may generate the health parameter information based on a signal having the higher stability and selected from the red light signal and the green light signal.
In some embodiments, the health testing is performed with the red light and the green light. It is usually necessary to configure corresponding light emitting ends, such as the red light emitting end in the electronic device and configured to emit the red light, and the green light emitting end in the electronic device and configured to emit the green light. Certainly, since the optical fingerprint module in the electronic device can emit light itself, the red light and/or green light used for the health testing can be emitted by the optical fingerprint module.
In some embodiments, the obtained health parameter information may include any of: heart rate, blood oxygen, and blood pressure. Certainly, the above is only an example and illustrative. It should be understood that any parameter that can reflect the state of health can be used as the health parameter information of the present disclosure. The specific health parameter information obtained is related to the method for processing the health signal, which is not limited in the present disclosure.
It can be seen from the above technical solutions that by collecting the red light and the green light for the health testing through the optical fingerprint module, and comparing the red light signal obtained by processing the red light and the green light signal obtained by processing the green light, the health parameter information may be generated based on the signal having the higher stability. In other words, the accuracy of health testing may be improved in the present disclosure by selecting the better one from the red light signal and the green light signal.
