DETAILED DESCRIPTION
[0052] The features and principles of the present invention are described in detail below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the protection scope of the present invention.
[0053] In order to solve the technical problem in the prior art that the health monitoring module is set in the non-display area of the screen, which is not conducive to full-screen design, a display device and a data monitoring method are provided in the embodiments of the present invention, which can realize full-screen design while realizing real-time monitoring of the user's health indicators and other monitoring data.
[0054] The following is an exemplary description of an embodiment of the display device provided by the present invention.
[0055] like Figures 1 to 6 As shown, the display device provided by the embodiment of the present invention includes:
[0056] A display module 100, wherein a display area of the display module 100 is provided with a plurality of pixel units, and each of the pixel units is provided with a corresponding plurality of light-emitting units;
[0057] The touch module 200 is disposed on one side of the display module 100 and corresponds to the entire display area, and is used to sense touch information of a finger, wherein the touch information includes a touch position;
[0058] The control module 300 is connected to the touch module 200 and the display module 100, and is used to control the light-emitting unit in the pixel unit at the touch position to emit light, or control the pixel unit at the touch position to display according to the touch information;
[0059] The light sensing module 400 is disposed on one side of the display module 100 and corresponds to the entire display area, and is used to sense the light emitted by the light emitting unit at the touch position and convert it into an electrical signal;
[0060] The data processor 500 is used to process the electrical signal of the light sensing module 400 to obtain monitoring data, and display the monitoring data through the display module 100 .
[0061] In the above scheme, a light sensing module 400 is provided in full screen corresponding to the entire display area of the display module 100, and the light-emitting unit in the display module 100 is used as the sensing light source of the light sensing module 400 (that is, the light sensing module 400 can sense the light emitted by the light-emitting unit of the display module 100), and the touch module 200 is used to obtain touch information such as the touch position of the finger. In this way, when the user touches a certain position of the screen with his finger during use, the touch module can feed back the touch information to the control module 300, and the control module 300 drives the light-emitting unit in the pixel unit at the finger touch position to emit light. The light sensing module 400 senses the light emitted by the light-emitting unit at the finger touch position, converts it into an electrical signal, and sends it to the data processor 500. The data processor 500 processes the received electrical signal to obtain monitoring data. When the user moves the finger away from the screen, the touch module feeds back the touch information of the finger moving away to the control module 300. The control module 300 stops the light-emitting unit corresponding to the finger touch position from emitting light through the driving chip, and restores the previous display screen of the pixel unit at the finger touch position, thereby not affecting the normal display of the screen.
[0062] It can be seen that the display device and data monitoring method provided by the present invention, since the light sensing module 400 is set corresponding to the entire display area, and the touch module 200 set corresponding to the entire display area is used to obtain finger touch information, and the light-emitting unit of the entire display module 100 is used as the sensing light source of the light sensing module 400, the purpose of real-time monitoring of the user's health indicators and other monitoring data can be achieved, and the light sensing module, touch module and light-emitting unit can all be designed as full-screen, and there is no need to separately package them in the non-display area of the screen. Compared with the prior art method of separately packaging the health monitoring module and sticking it on the non-display area of the screen, a full-screen design can be achieved.
[0063] It should be noted that, in the above scheme, the display module 100 can be an OLED (Organic Light-Emitting Diode) display module, wherein the light-emitting unit may include a cathode, an anode and a light-emitting layer located between the cathode and the anode, and the light-emitting layer generally includes a hole injection layer, a hole transport layer, an organic light-emitting layer, an electron transport layer and an electron injection layer, etc. The control module 300 can drive the light-emitting layer to emit light by controlling the electric field between the cathode and the anode.
[0064] In the above solution, the control module 300 can drive the light-emitting unit in the pixel unit at the finger touch position to only emit light through the driving chip 310, or drive the pixel unit at the finger touch position to display normally through the driving chip.
[0065] Of course, it is understandable that the display module 100 is not limited to the OLED display module, but can also be other types of display modules. For example, the display module 100 can also be a QLED (Quantum Dot Light Emitting Diodes) display module or an AMOLED display module.
[0066] In addition, it should be noted that in the above scheme, the touch module 200 may include a touch layer 201 and a touch chip 202. The touch layer 201 may be adhered to or directly formed on the light-emitting side of the display module 100 to generate a capacitance change at the finger touch position. The touch chip 202 is used to read the capacitance change of the touch layer and convert it into touch information to feed back to the control module 300.
[0067] In addition, in the display device provided in the embodiment of the present invention, exemplarily, each of the pixel units includes a plurality of sub-pixels capable of emitting light of different colors, for example, the plurality of sub-pixels include a first sub-pixel, a second sub-pixel, a third sub-pixel, etc., and a light-emitting unit is provided corresponding to each of the sub-pixels, and the light-emitting unit corresponding to each sub-pixel may be a first light-emitting unit emitting light of a first color, a second light-emitting unit emitting light of a second color, and a third light-emitting unit emitting light of a third color, etc. For example, each of the pixel units may include red, green, and blue (RGB) three-color sub-pixels, or may also include red, green, blue, and white (RGBW) four-color sub-pixels, and a light-emitting unit is provided corresponding to each sub-pixel.
[0068] Preferably, the control module 300 can control the light-emitting unit in the pixel unit to emit light or control the pixel unit to display through the driving chip 301. The control module 300 specifically includes:
[0069] A first driving unit, configured to drive a first light-emitting unit corresponding to a sub-pixel emitting a first color light in the pixel unit at the touch position to emit light according to the touch information;
[0070] The second driving unit is used to control the light-emitting units corresponding to the sub-pixels other than the sub-pixel emitting the first color light in the pixel unit at the touch position not to emit light according to the touch information.
[0071] By adopting the above scheme, the light sensing module 400 can exemplarily sense the first color light, that is, by sensing the first color light emitted by the first light-emitting unit in the pixel unit, to obtain a sensing signal. Therefore, when the user touches a certain position of the screen with his finger during use, the touch module can feed back the finger touch information to the control module 300. The control module 300 drives the first light-emitting unit in the pixel unit at the finger touch position to emit the first color light, and drives other color lights in the pixel unit at the finger touch position to turn off. In this way, only the first color light can be emitted at the finger touch position, preventing the reflected light of other color lights from interfering with the light sensing module 400 sensing the first color light, thereby increasing the accuracy of data monitoring.
[0072] Exemplarily, the first color light is green light, and the intensity of the light emitted by the first light emitting unit is a fixed intensity.
[0073] By adopting the above scheme, the light that can be sensed by the light sensing module 400 is green light, and the control module 300 drives the first light-emitting unit at the finger touch position to emit green light of preferably fixed intensity, and the light sensing module 400 can only receive the green light of the fixed intensity. In this way, the user's heart rate and other factors will cause the green light of fixed intensity to change, so that the light sensing module 400 reads the signal change of the green light and obtains the induced electrical signal to ensure the accuracy of the monitoring data.
[0074] It should be noted that, in the above solution, the intensity of the first color light in at least one pixel unit at the finger touch position is a fixed intensity.
[0075] In addition, it should be understood that in actual applications, when other data needs to be monitored, the light sensing module 400 can be designed according to actual needs as a light sensing module 400 that can sense other colors of light. Accordingly, the control module 300 can drive the light-emitting unit of the color light that the light sensing module 400 can sense at the finger touch position to emit light, and drive other colors of light to be turned off.
[0076] For example, Figure 6 As shown, the light sensing module 400 includes:
[0077] A plurality of light sensors 401, each of the light sensors 401 is arranged corresponding to at least one pixel unit 101;
[0078] And, a first receiving module is used to receive control parameters to control the light sensor 401 at the touch position to turn on or off, and the control parameters include: control parameters generated by the control module 300 according to the touch information, or control parameters input by the user.
[0079] With the above solution, in the display module 100, the pixel units 101 are distributed in an array, and the light sensors 401 are preferably also distributed in an array, and one light sensor 401 can be arranged corresponding to at least one pixel unit 101, for example, Figure 6 As shown in the figure, one light sensor 401 is arranged corresponding to four pixel units 101 located around it. Of course, in practical applications, the number of pixel units 101 to which one light sensor 401 can correspond is not limited; and in the above scheme, the opening or closing of the light sensor 401 can be controlled by the control module 300 (such as Figure 6 As shown, a control switch 600 is provided between the control module 300 and each light sensor 401. The control module 300 controls the light sensor 401 to turn on or off according to the touch information of the touch module 200. Specifically, when the user touches a certain position of the screen with his finger during use, the touch module 200 can feed back the finger touch information to the control module 300, and the control module 300 drives the light sensor 401 at the finger touch position to turn on; when the finger moves away from the screen, the touch module 200 feeds back the touch information of the finger moving away to the control module 300, and the control module 300 drives the light sensor 401 at the finger touch position to turn off. In this way, the light sensing module does not need to be in the on state all the time, which can reduce power consumption.
[0080] Of course, it is understandable that the light sensor 401 may be uncontrolled by the control module 300 and always in working state, but this will increase power consumption; alternatively, the light sensor 401 may be controlled to turn on or off by control parameters input by the user.
[0081] In addition, if Figures 2 to 5 As shown, exemplarily, the display module 100 may include:
[0082] Base substrate (not shown in the figure);
[0083] A driving circuit layer 110 formed on the base substrate;
[0084] The light emitting unit 120 is disposed on the driving circuit layer 110;
[0085] and, an encapsulation layer 130 encapsulating the light emitting unit 120;
[0086] The touch layer 201 of the touch module 200 is disposed on the packaging layer 130 ;
[0087] The optical sensor 401 is integrated with the driving circuit layer 120 , or the optical sensor 401 is attached to a side of the base substrate away from the light emitting unit 120 .
[0088] With the above scheme, the data monitoring principle of the display device provided in the embodiment of the present invention adopts reflective light sensing, that is, the first color light emitted by the light-emitting unit is emitted to the user's finger through the display surface of the display screen, and the light sensing module 400 senses the first color light reflected back by the user's finger, thereby obtaining monitoring data. Therefore, the light sensing module 400 can be integrated in the driving circuit layer on the substrate (such as Figures 2 to 4 ), or it can be attached to the back of the screen of the entire display module 100 (as shown in Figure 5 shown).
[0089] In addition, for example, Figure 3 and Figure 4 As shown, a light-transmitting hole 402 or a lens structure 403 is provided on the substrate at a position directly opposite to each of the light sensors 401 .
[0090] By adopting the above solution, no special design is required between the light sensing module 400 and the light emitting layer of the light emitting unit (such as Figure 2 and Figure 5 As shown), a light-transmitting hole 402 may also be added (as shown Figure 3 ) or lens structure 403 (as shown Figure 4 to eliminate the interference of stray light.
[0091] In addition, it should be noted that the display device provided in the embodiment of the present invention does not limit the specific structure and size of the light sensor 401. There may be only one light sensor 401 or multiple light sensors 401 within the contact area between the finger and the screen. In addition, the total area of the pixel unit 101 emitting green light of a fixed intensity preferably does not exceed the contact area between the finger and the screen, so that the display screen viewed by the user during use will not be affected by the pixel unit 101 only emitting light at the finger touch position.
[0092] In addition, it should be noted that when using a display device such as a mobile phone, the user's finger is in contact with the screen for a large part of the time, but the contact position will change over time. Therefore, in the display device provided in the embodiment of the present invention, the final monitored data result is obtained by fitting multiple sets of data. Specifically, the data processor 500 includes:
[0093] A second receiving module, used to receive an electrical signal from the light sensing module 400, wherein the electrical signal includes a waveform curve of light intensity sensed by the light sensing module 400 in different time periods;
[0094] The data integration module is used to integrate the light intensity waveform curves sensed by the light sensing module 400 in different time periods according to the electrical signal to obtain the monitoring data.
[0095] Using the above solution, if Figure 7 and Figure 8 As shown, during use by the user, the data processor 500 will obtain a series of monitoring data in different time periods. The data processor 500 performs fitting and calculation based on these original series of monitoring data in different time periods to obtain the final required monitoring data.
[0096] Generally speaking, Figure 7 As shown in the figure, the monitoring data monitored in each time period can obtain a corresponding light intensity waveform curve. The frequency and intensity of the light intensity waveform curves at different times are not completely consistent. Therefore, for the light intensity waveform curve in each time period, as long as the waveform between the first light intensity extreme point (the lowest light intensity point) and the last light intensity extreme point (the highest light intensity point) is intercepted, and then the waveforms in all time periods are spliced and integrated together in chronological order, a complete light intensity waveform curve can be obtained ( Figure 8 Through this complete light waveform curve, the user's health indicators (such as heart rate, etc.) monitoring data can be obtained.
[0097] It should be noted that the length of the time period can be set by the display device at the system end when it leaves the factory, or some alternative schemes can be made for the user to select and set.
[0098] It should be noted that, in actual applications, the data processor 500 may not be limited to this method for processing the electrical signal data, but may also adopt other methods. For example, when obtaining the light intensity waveform curve of each time period (position 1, position 2, position 3...position n), a sub-indicator A1, A2, A3...An in each time period may be calculated (for example, the sub-indicator may be the average light intensity value in each time period), and then the sub-indicators in each time period may be statistically calculated to obtain the user's health indicators (such as heart rate, etc.) monitoring data.
[0099] In addition, an embodiment of the present invention further provides a data monitoring method, which is applied to the display device provided in the embodiment of the present invention, and the method includes:
[0100] Step S1, the touch module 200 senses touch information of a finger;
[0101] Step S2, the control module 300 controls the light-emitting unit in the pixel unit 101 at the touch position to emit light, or controls the pixel unit 101 at the touch position to display, according to the touch information;
[0102] Step S3, the light sensing module 400 senses the light emitted by the light emitting unit at the touch position and converts it into an electrical signal;
[0103] Step S4 : the data processor 500 processes the electrical signal of the light sensing module 400 to obtain monitoring data, and displays the monitoring data through the display module 100 .
[0104] In the above scheme, a light sensing module 400 is provided in full screen corresponding to the entire display area of the display module 100, and the light-emitting unit in the display module 100 is used as the sensing light source of the light sensing module 400 (that is, the light sensing module 400 can sense the light emitted by the light-emitting unit of the display module 100), and the touch module 200 is used to obtain touch information such as the touch position and touch time of the finger. In this way, when the user touches a certain position of the screen with his finger during use, the touch module can feed back the touch information to the control module 300, and the control module 300 drives the light-emitting unit in the pixel unit 101 at the finger touch position to generate a light source. When the unit emits light, the light sensing module 400 will sense the light emitted by the light-emitting unit at the finger touch position, and convert it into an electrical signal, and send it to the data processor 500. The data processor 500 processes the received electrical signal to obtain monitoring data; when the user's finger moves away from the screen, the touch module will feed back the touch information of the finger moving away to the control module 300, and the control module 300 will stop the light-emitting unit corresponding to the finger touch position through the driving chip, and restore the previous display screen of the pixel unit 101 at the finger touch position, so as not to affect the normal display of the screen. It can be seen that the data monitoring method provided by the present invention can achieve the purpose of real-time monitoring of the user's health indicators and other monitoring data, and compared with the prior art, it can achieve a full-screen design of the display device.
[0105] Exemplarily, in the method, step S2 specifically includes:
[0106] The control module 300 drives the first light-emitting layer corresponding to the sub-pixel emitting the first color light in the pixel unit 101 at the touch position to emit light according to the touch information; and controls the light-emitting units corresponding to other sub-pixels in the pixel unit 101 at the touch position except the sub-pixel emitting the first color light not to emit light.
[0107] By adopting the above scheme, the light sensing module 400 can exemplarily sense the first color light, that is, by sensing the first color light emitted by the first light-emitting unit in the pixel unit 101, a sensing signal is obtained. Therefore, when the user touches a certain position of the screen with his finger during use, the touch module can feed back the finger touch information to the control module 300. The control module 300 drives the first light-emitting unit in the pixel unit 101 at the finger touch position to emit the first color light, and drives other color lights in the pixel unit 101 at the finger touch position to turn off. In this way, only the first color light can be emitted at the finger touch position, preventing the reflected light of other color lights from interfering with the light sensing module 400 sensing the first color light, thereby increasing the accuracy of data monitoring.
[0108] Exemplarily, the first color light is green light, and the intensity of the light emitted by the first light emitting unit is a fixed intensity.
[0109] By adopting the above scheme, the light that can be sensed by the light sensing module 400 is green light, and the control module 300 drives the first light-emitting unit at the finger touch position to emit green light of preferably fixed intensity, and the light sensing module 400 can only receive the green light of the fixed intensity. In this way, the user's heart rate and other factors will cause the green light of fixed intensity to change, so that the light sensing module 400 reads the signal change of the green light and obtains the induced electrical signal to ensure the accuracy of the monitoring data.
[0110] It should be noted that, in the above solution, the intensity of the first color light in at least one pixel unit 101 at the finger touch position is a fixed intensity.
[0111] In addition, it should be understood that in actual applications, when other data needs to be monitored, the light sensing module 400 can be designed according to actual needs as a light sensing module 400 that can sense other colors of light. Accordingly, the control module 300 can drive the light-emitting unit of the color light that the light sensing module 400 can sense at the finger touch position to emit light, and drive other colors of light to be turned off.
[0112] Exemplarily, in step S3, the light sensing module 400 receives control parameters to control the light sensor 401 at the touch position to turn on or off, and the control parameters include: control parameters generated by the control module 300 according to the touch information, or control parameters input by the user.
[0113] With the above solution, in the display module 100, the pixel units 101 are distributed in an array, and the light sensors 401 are preferably also distributed in an array, and one light sensor 401 can be arranged corresponding to at least one pixel unit 101, for example, Figure 6As shown in , one light sensor 401 is set corresponding to four pixel units 101 located around it. Of course, in practical applications, the number of pixel units 101 that one light sensor 401 can correspond to is not limited; and in the above scheme, the opening or closing of the light sensor 401 can be controlled by the control module 300, and the control module 300 controls the opening or closing of the light sensor 401 according to the touch information of the touch module 200. Specifically, when the user touches a certain position of the screen with his finger during use, the touch module can feed back the finger touch information to the control module 300, and the control module 300 drives the light sensor 401 at the finger touch position to turn on; when the finger moves away from the screen, the touch module feeds back the touch information of the finger moving away to the control module 300, and the control module 300 drives the light sensor 401 at the finger touch position to turn off. In this way, the light sensing module does not have to be in the on state all the time, which can reduce power consumption.
[0114] Of course, it is understandable that the light sensor 401 may be uncontrolled by the control module 300 and always in working state, but this will increase power consumption; alternatively, the light sensor 401 may be controlled to turn on or off by control parameters input by the user.
[0115] Exemplarily, the step S4 specifically includes:
[0116] The data processor 500 receives the electrical signal of the light sensing module 400, wherein the electrical signal includes the light intensity waveform curve sensed by the light sensing module 400 in different time periods; and according to the electrical signal, integrates the light intensity waveform curve sensed by the light sensing module 400 in different time periods to obtain the monitoring data.
[0117] Using the above solution, if Figure 7 and Figure 8 As shown, during use by the user, the data processor 500 will obtain a series of monitoring data in different time periods. The data processor 500 performs fitting and calculation based on these original series of monitoring data in different time periods to obtain the final required monitoring data.
[0118] Generally speaking, the monitoring data monitored in each time period can obtain a corresponding light intensity waveform curve. The frequency and intensity of the light intensity waveform curve at different times will not be completely consistent. Therefore, for the light intensity waveform curve in each time period, as long as the waveform between the first light intensity extreme point (the lowest light intensity point) and the last light intensity extreme point (the highest light intensity point) is intercepted, and then the waveforms in all time periods are spliced and integrated together in chronological order, a complete light intensity waveform curve can be obtained. Through this complete light waveform curve, the user's health indicators (such as heart rate, etc.) monitoring data can be obtained.
[0119] It should be noted that the length of the time period can be set by the display device at the system end when it leaves the factory, or some alternative schemes can be made for the user to select and set.
[0120] It should be noted that, in actual applications, the data processor 500 may not be limited to this method for processing the electrical signal data, but may also adopt other methods. For example, when obtaining the light intensity waveform curve of each time period (position 1, position 2, position 3...position n), a sub-indicator A1, A2, A3...An in each time period may be calculated (for example, the sub-indicator may be the average light intensity value in each time period), and then the sub-indicators in each time period may be statistically calculated to obtain the user's health indicators (such as heart rate, etc.) monitoring data.
[0121] The above is a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
