In addition, in this way, the first electrode and the second electrode can be directly powered by using the circuit component inside the shell, and independent power supply is not needed, which is beneficial to reducing development difficulty and cost. Furthermore, the first electrode is arranged on the display screen, so that the appearance design of the electrocardio detection device is not influenced, and the electrocardio detection device is more attractive.

In a first aspect, the application provides an electrocardiograph detection device, which comprises a shell, a circuit component, a first electrode and a second electrode, wherein the circuit component is arranged inside the shell, the shell can comprise a display screen and a back shell, the display screen is arranged on a first surface of the shell, the back shell is arranged on a second surface of the shell, and the first surface and the second surface are two surfaces which are arranged oppositely. The first electrode is arranged on the display screen, the second electrode is arranged on the back shell, and the first electrode and the second electrode are respectively and electrically connected with the circuit component. Therefore, when the user wears the electrocardio detection device, the first skin measuring point positioned on one side of the heart is pressed on the first electrode, the first electrode can collect the first electric signal of the first skin measuring point and transmit the first electric signal to the circuit component, the second electrode can contact the second skin measuring point positioned on the other side of the heart to collect the second electric signal of the second skin measuring point and transmit the second electric signal to the circuit component, and then the circuit component carries out electrocardio detection on the user according to the first electric signal and the second electric signal.

In the above design, the first electrode and the second electrode are arranged on the two oppositely arranged surfaces, when the user presses the first electrode, the second electrode can be attached to the skin of the user, so that the two electrodes can collect stable electric signals, and therefore the electric signals at the two ends of the heart of the user can be collected through the first electrode and the second electrode respectively, and the electrocardio detection device can achieve the electrocardio detection function well. And the first electrode and the second electrode can also be directly powered by using circuit components inside the shell, so that independent power supply is not required. Furthermore, the first electrode is arranged on the display screen, so that the influence of the electrocardio detection function on the appearance design of the electrocardio detection device can be lightened, and the electrocardio detection device is more attractive.

In one possible design, the first electrode comprises a transparent conductive layer, which covers the display screen, or which covers a local area of the display screen. Wherein, the light transmittance of the transparent conductive layer can be more than 50%. Through the design, even if the first electrode is arranged on the screen, the influence of the first electrode on the display function of the display screen is small, so that the appearance color value of the electrocardio detection device is improved, and the degree of freedom of appearance design is increased.

In a possible design, when the transparent conductive layer covers a local area of the display screen, the circuit component can also display the area where the transparent conductive layer is located on the display screen after detecting that the user triggers the electrocardiographic detection function, so that the user can conveniently obtain the position where the transparent first electrode is located, and the first skin measurement point is accurately pressed on the first electrode.

In one possible design, the transparent conductive layer is formed from an indium tin oxide, aluminum-doped zinc oxide, fluorine-doped tin oxide, or molybdenum coating. With this design, the conductive performance of the transparent conductive layer made of the above material can be significantly improved as compared with a case where a metal sheet or conductive ceramic is used as an electrode.

In one possible design, the thickness of the transparent conductive layer is no greater than 5 microns. Through the design, the sheet resistance of the transparent conducting layer can be controlled to be 50000 ohms or below, so that the conducting performance of the transparent conducting layer is better, and the first electrode is facilitated to accurately acquire the electric signal of the first skin measuring point.

In one possible design, the first electrode may further include one or more of a transition layer, a protective layer, and a low resistance ultra-hard layer. When the first electrode simultaneously comprises the transition layer, the transparent conducting layer, the protective layer and the low-resistance superhard layer, the transition layer is positioned between the transparent conducting layer and the display screen, and the protective layer is positioned between the transparent conducting layer and the low-resistance superhard layer. Through this design, first electrode not only can have better electric conductive property, and the wear resistance and the hardness of first electrode also can obtain promoting.

In one possible design, when the first electrode further comprises a protective layer, the thickness of the protective layer is not more than 1 micrometer. Through this design, even the electric conductivity of protective layer is relatively poor, also can reduce the protective layer to the influence of the electric conductivity of first electrode.

In one possible design, the first electrode includes a shielding conductive layer covering a local area of the display screen, the local area being located in a non-display area of the display screen. Through the design, even if the first electrode is in a shielding structure, the first electrode does not influence a display area of the display screen viewed by a user, and the influence of the first electrode on the display performance of the display screen is small.

In one possible design, the shielding conductive layer is formed of one or more plating films of gold, silver, aluminum, copper, chromium, nickel, titanium, molybdenum, tungsten, gold oxide, silver oxide, aluminum oxide, copper oxide, chromium oxide, nickel oxide, titanium oxide, molybdenum oxide, and tungsten oxide. In this way, the conductive performance of the shielding conductive layer made of the above-described material can be greatly improved as compared with a case where a metal sheet or a conductive ceramic is used as an electrode.

In one possible design, the thickness of the masking conductive layer is no greater than 10 microns. Through the design, the sheet resistance of the shielding conductive layer can be controlled to be 50000 ohms or below, so that the conductive performance of the shielding conductive layer is better, and the first electrode is facilitated to accurately acquire the electric signal of the first skin measuring point.

In one possible design, the first electrode further comprises one or more of a transition layer, an oxidation prevention layer, a protective layer, and a low resistance ultrahard layer. When the first electrode simultaneously comprises the transition layer, the shielding conductive layer, the anti-oxidation layer, the protective layer and the low-resistance superhard layer, the transition layer is positioned between the conductive layer and the display screen, the anti-oxidation layer is positioned between the conductive layer and the protective layer, and the protective layer is positioned between the anti-oxidation layer and the low-resistance superhard layer. Through this design, first electrode not only can have better electric conductive property, and the wear resistance and the hardness of first electrode also can obtain promoting.

In one possible design, when the first electrode further comprises a protective layer, the thickness of the protective layer is not more than 1 micrometer. Thus, even if the conductive performance of the protective layer is poor, the influence of the protective layer on the conductive performance of the first electrode can be reduced.

In one possible design, the first electrode includes conductive wires arranged in a staggered manner, and a grid area of the conductive wires covers the display screen, or a grid area of the conductive wires covers a partial area of the display screen. By this design, the first electrode can occupy a smaller area on the display screen, helping to reduce the cost of the first electrode while maintaining the conductivity of the first electrode.

In one possible design, when the conductive lines are transparent conductive lines, the width of each conductive line is greater than 1 micron. Thus, since a transparent conductive line is not originally visible, the wider the line width, the greater the conductive performance of the conductive line.

In a possible design, when the conductive lines are shielding conductive lines, the width of each conductive line is not more than 6 microns, and by the design, the texture structure of the conductive lines on the display screen can be thinned as much as possible under the condition that the conductive performance of the first electrode is guaranteed, so that the possibility that a user cannot see is improved.

In one possible design, the first conductive connecting member is a conductive adhesive or a conductive adhesive backing. Therefore, the first electrode and the circuit component can be electrically connected in a mode of pasting the first conductive connecting piece, the operation is simple, and the realization is convenient.

In one possible design, a slot is formed in the side face of the display screen, conductive materials are filled in the slot, the upper surface and the side face of the slot are open, the upper surface of the conductive materials is in contact with the lower surface of the first electrode, and the side face of the conductive materials is in contact with the first conductive connecting piece. Through the design, the first electrode can be in direct contact with the first conductive connecting piece through the side edge and the bottom surface of the first electrode can be in contact with the first conductive connecting piece through the conductive material in the groove, so that the contact area between the first electrode and the first conductive connecting piece is enlarged, and the stability of electric connection between the first electrode and the first conductive connecting piece is improved.

In a possible design, the side of display screen is equipped with the fluting, the inslot is filled with conducting material, the upper surface in groove, the equal opening in lower surface and side, conducting material's upper surface and the lower surface contact of first electrode, conducting material's side and lower surface contact with first electrically conductive connecting piece respectively, through this design, not only can increase the area of contact of first electrode and first electrically conductive connecting piece, still with the area of contact of increase conducting material and first electrically conductive connecting piece, help further improving the stability of the electricity connection between first electrode and the first electrically conductive connecting piece.

The ECG electrodes in the embodiments of the present application refer to: electrodes for measuring changes in electrical signals on the surface of the living being due to the heartbeat. When the ECG electrodes are used for measuring electric signals, the plurality of ECG electrodes and bioelectric currents on the left side and the right side of the heart need to form a closed loop, so that the electric signals at different positions of the body surface of a living being are detected according to the plurality of ECG electrodes, amplified by an amplifier and traced by a recorder, and an electrocardiogram can be obtained.

However, in this embodiment, since the crown button is disposed at a side of the wearable watch, when the user presses the electrode on the crown button, the electrode on the back case is likely to be in poor contact with the wrist due to the influence of the finger pushing force, so that the electrocardiographic detection device cannot acquire a stable electrical signal, which affects the accuracy of electrocardiographic detection. In order to solve this problem, in another alternative embodiment, one electrode may be designed on the front side of the band of the wearable watch, and the other electrode may be designed on the back side of the band of the wearable watch. When carrying out the electrocardio and detecting, the user can press the opposite side finger on the positive electrode of watchband, so, receives the influence of finger thrust to make the electrode and the wrist contact ground at the watchband back inseparabler to stable signal of telecommunication can both be gathered to two electrodes. However, in order to improve the user experience, most of wearable watches at the present stage are provided with a detachable watchband, and are usually provided with a plurality of colors, in this case, two electrodes are designed on the watchband, and it is obviously necessary to independently supply power to the two electrodes on each watchband, which not only increases the cost, but also increases the difficulty of development. And, set up independent power supply in the watchband still can make the thickness of watchband increase, influence user's wearing experience and impression.

In view of this, the application provides an electrocardio detection device, this electrocardio detection device sets up first electrode on the display screen of casing, sets up the second electrode on the dorsal scale that the display screen is relative, so, when the user pressed first electrode, the second electrode also can paste user's skin closely to stable signal of telecommunication can both be gathered to two electrodes, so, gather the signal of telecommunication at user's heart both ends respectively through first electrode and second electrode, make electrocardio detection device can be better realization electrocardio detection function. In addition, in the mode, the first electrode and the second electrode can directly use the circuit part inside the shell for power supply without independent power supply, development difficulty and cost are reduced, and wearing experience of a user is improved. Furthermore, the first electrode is arranged on the display screen, so that the appearance design of the electrocardio detection device is not influenced, and the electrocardio detection device is more attractive.

The second electrode on the back shell can contact with a second skin measurement point of the user when the user wears the electrocardiograph detection device. In the embodiment of the application, when carrying out the electrocardio and detecting, the user can press first skin measuring point on first electrode, this kind of pressure can make the contact of second electrode and user's second skin measuring point more inseparable, under this condition, not only first electrode can accurately gather the first signal of telecommunication of first skin measuring point and transmit circuit component, the second electrode also can accurately gather the second signal of telecommunication of second skin measuring point and transmit circuit component, and then carry out the electrocardio by circuit component according to first signal of telecommunication and second signal of telecommunication and detect the user.

Illustratively, when the electrocardiographic detection device is a wearable watch, the first skin measurement point may be a finger of a left hand of the user and the second skin measurement point may be a wrist of a right hand of the user. Alternatively, the first skin measurement point may be a right hand finger of the user and the second skin measurement point may be a left hand wrist of the user. By adopting the design, the first electrode and the second electrode can collect stable electric signals, the accuracy of the electrocardio detection device for collecting the electric signals is improved, and the circuit part in the shell can be directly used for supplying power without independent power supply. And, through setting up first electrode on the display screen, can also thin out the influence that adds the electrocardio and detect the function and to the appearance design of wearable wrist-watch, help making wearable wrist-watch more pleasing to the eye.

In the embodiment of the present application, "the first electrode is disposed on the display screen" is only an optional implementation manner, and in other optional implementation manners, the first electrode may also be disposed on other transparent objects, for example, a Cover Glass (CG), ruby, sapphire, crystal, transparent plastic, or diamond, which is attached above the display screen. For example, in one case, the electrocardiograph detection device may be a ring, the first electrode is provided on a gem surface of the ring, the second electrode is provided on a surface of the ring holder which is in contact with the skin of the finger, and the first electrode and the second electrode are electrically connected to a circuit component provided inside the ring holder. When carrying out the electrocardio and detecting, the user can press the opposite side finger on the precious stone face of ring, and this pressure can make the contact of second electrode and finger skin more inseparable, so, ring and hold in the palm the inside circuit part and can carry out the electrocardio according to the first signal of telecommunication that first electrode gathered and the second signal of telecommunication that the second electrode gathered and detect. The ring and other daily worn articles are used as the electrocardio detection device, so that the electrocardio detection can be carried out at any time even if the user does not carry other devices, and the user experience is better.

In an optional embodiment, the electrocardiograph detection device may further include a third electrode, and the third electrode may also be disposed on the back shell, for example, the third electrode and the second electrode may be packaged as a whole, or the third electrode and the second electrode may also be separately disposed. When carrying out the electrocardio and examining time, the noise signal that the second skin measuring point can be gathered to the third electrode and the transmission gives circuit part, so, circuit part can use the noise signal that the third electrode was gathered earlier to carry out noise compensation to the second signal of telecommunication that the second electrode was gathered and the first signal of telecommunication that the first electrode was gathered, uses the second signal of telecommunication and the first signal of telecommunication after the noise compensation again to draw the heart electrograph to reduce the interference of noise to electrocardio detection, improve electrocardio detection's accuracy.

In the embodiments of the present application, there are many possible structures of the first electrode, and several possible structures of the first electrode are described in the first to third embodiments, respectively.

Example one

Fig. 3 schematically illustrates a structure of the first electrode provided in the first embodiment of the present application, and as shown in fig. 3, the first electrode may cover the entire display screen. In this case, the first electrode may be a transparent structure with a light transmittance of more than 50%, so as to minimize the influence of the first electrode on the display function of the display screen, improve the appearance color value of the electrocardiograph detection device, and increase the degree of freedom of appearance design. In an alternative example, in order to better improve the viewing experience of the user, the light transmittance of the first electrode may also be set to be more than 75%.

In an embodiment of the present application, the first electrode may include a transparent conductive layer. The transparent conductive layer may be formed by coating one or more transparent materials selected from indium tin oxide, aluminum-doped zinc oxide, fluorine-doped tin oxide, and molybdenum, and the coating process is not limited to a physical method or a chemical method, and may be performed by one or more methods selected from magnetron sputtering, chemical vapor deposition, sol-gel method, hydrothermal method, coating method, spray pyrolysis method, and evaporation method. For example, in order to improve the scratch resistance of the first electrode, a transparent conductive layer may also be formed by sputtering a transparent material (e.g., indium tin oxide) and a superhard coating target material at the same time, so as to improve the scratch resistance of the transparent conductive layer by the uniform composite characteristic of the film layer.

In an alternative embodiment, the thickness of the transparent conductive layer may be not greater than 5 μm, so that the sheet resistance of the transparent conductive layer can be not greater than 50000 ohms by forming the transparent conductive film with the thickness by the transparent material, and compared with a scheme using a metal sheet or conductive ceramic as an electrode, the thickness and the conductivity of the transparent conductive layer can support the first electrode to accurately acquire the electric signal of the first skin measuring point. Illustratively, in order to further improve the stability of the electrical conductivity of the transparent conductive layer, in a preferred example, the thickness of the transparent conductive layer is not more than 3 micrometers, so as to control the sheet resistance of the transparent conductive film to be less than 100 ohms, in this way, the electrical conductivity of the transparent conductive layer is greatly improved, thereby helping to improve the accuracy and stability of the first electrode for acquiring the electrical signal of the first skin measurement point.

In an alternative embodiment, the first electrode may further include one or more of a transition layer, a protective layer, and a low resistance ultra-hard layer. When the first electrode simultaneously comprises the transition layer, the transparent conducting layer, the protective layer and the low-resistance superhard layer, then:

the transition layer can be arranged between the transparent conducting layer and the display screen, and the transition layer is used for improving the combination rate of the transparent conducting layer and the display screen. Wherein the transition layer can be made of silicon dioxide SiO₂The coating film may be formed of silicon dioxide SiO₂And titanium oxide TiO₂And forming a composite coating.

The protective layer can be arranged above the conductive layer and used for isolating the first skin measuring point from the transparent conductive layer so as to prevent the first skin measuring point from directly pressing on the transparent conductive layer and reduce the probability of abrasion of the transparent conductive layer. Wherein the protective layer may be made of silicon nitride Si₃N₄Or a coating of silicon carbide SiC, or a diamond-like film, a ceramic film, SiO₂A film, etc., canSo as to mean a composite film system of two or more of the above. In the embodiment of the application, because the conductivity of the protective layer is poor, the thickness of the protective layer can be set to be less than 1 micrometer, so as to reduce the influence of the protective layer on the conductivity of the first electrode. Alternatively, in an alternative example, the protective layer may be provided with a thickness of less than 500nm, in which case the protective layer is actually a very thin film, so that the electrical signal of the first skin measurement point can well penetrate through the film to the transparent conductive layer, which helps the transparent conductive layer to better acquire the electrical signal of the first skin measurement point.

The low resistance superhard layer can set up in the top of protective layer, and the hardness of low resistance superhard layer can be greater than 4H, so, through the hardness that improves first electrode, help avoiding first skin measuring point to press the structure of first electrode when pressing first electrode and cause the destruction. The low-resistance superhard layer can be formed by one or more composite coating films of a titanium aluminum nitride TiAlN coating, an aluminum titanium nitride AlTiN coating or other superhard conductive coatings, and the coatings have conductivity, so the low-resistance superhard layer can also improve the conductivity of the protective layer.

In the embodiment of the present application, when the first electrode only includes the transparent conductive layer, the transparent conductive layer may be directly plated on the display screen, and when the first electrode further includes other coating layers, the layers may be sequentially stacked in the above manner to form the first electrode. In the embodiment of the application, the transmittance of the transparent first electrode is over 50%, so that the first electrode can be invisible visually, and the visual experience of a user watching a display screen and the visual experience of the user are not affected basically.

Example two

Fig. 4A and 4B exemplarily show two kinds of schematic structural diagrams of the first electrode provided in the second embodiment of the present application, in this embodiment, the first electrode may cover a local area of the display screen, for example, may cover a peripheral area of the display screen (as shown in fig. 4A), and may also cover a central area of the display screen (as shown in fig. 4B). In the embodiment of the present application, in order to make the first skin measurement point and the first electrode contact well, the area of the first electrode is large enough, for example, not less than 30 mm square. Thus, if the first electrode has the structure illustrated in fig. 4A, the area of the peripheral annular region where the first electrode is located is greater than or equal to 30 square millimeters. If the first electrode has the structure shown in fig. 4B, the area of the central circular region where the first electrode is located is greater than or equal to 30 square millimeters.

In an optional implementation manner, the first electrode may be a transparent structure with a light transmittance greater than 50%, and each hierarchical structure of the first electrode may refer to embodiment one, which is not described herein again. In this case, the local area may be located in any area on the display screen, such as a display area or a non-display area, since the first electrode itself is not visible for the purpose. Illustratively, since the first electrode covers a local area of the display screen, and the user does not know the specific position of the first electrode, in order to avoid affecting the electrocardiographic detection process, the circuit component may further display the area where the first electrode is located on the display screen to the user when detecting that the user triggers the electrocardiographic detection function, so that the user can accurately press the first skin measurement point on the first electrode.

In another alternative embodiment, the first electrode may be a shielding structure having a light transmittance of not more than 50%, such as an opaque structure or a semi-transparent structure. In this case, the local area needs to be located in the non-display area on the display screen, so that even if the first electrode is in a shielding structure, the first electrode does not affect the user to view the display area of the display screen, and the first electrode has a small influence on the display performance of the display screen.

In the embodiment of the present application, when the first electrode is a shielding structure, the first electrode may include a shielding conductive layer. The shielding conductive layer may be formed of one or more plating films of low-resistance materials such as gold, silver, aluminum, copper, chromium, nickel, titanium, molybdenum, tungsten, gold oxide, silver oxide, aluminum oxide, copper oxide, chromium oxide, nickel oxide, titanium oxide, molybdenum oxide, and tungsten oxide, or may be formed of other metal or metal oxide plating films, and the plating process is not limited to a physical method or a chemical method, and may be performed by one or more methods selected from a magnetron sputtering method, a chemical vapor deposition method, an electroplating method, a sol-gel method, a hydrothermal method, a coating method, a spray pyrolysis method, and an evaporation method, for example.

In an alternative embodiment, the thickness of the shielding conductive layer may be set between 0.2um and 10um, so that the sheet resistance of the shielding conductive layer is not greater than 50000 ohms by forming the shielding conductive film with the thickness by using the low-resistance material, and the conductivity of the shielding conductive layer with the thickness and the material can support the first electrode to accurately acquire the electrical signal of the first skin measurement point. Illustratively, in order to further improve the stability of the electrical conductivity of the transparent conductive layer, in a preferred example, the thickness of the shielding conductive layer is not more than 5 micrometers, so as to control the sheet resistance of the shielding conductive film to be less than 100 ohms, in this way, the electrical conductivity of the shielding conductive layer is greatly improved, thereby further improving the accuracy and stability of the first electrode for acquiring the electrical signal of the first skin measurement point.

In an optional embodiment, when the first electrode is a shielding structure, the first electrode may further include one or more of a transition layer, an oxidation prevention layer, a protective layer, and a low-resistance ultra-hard layer. When the first electrode simultaneously comprises the transition layer, the anti-oxidation layer, the shielding conductive layer, the protective layer and the low-resistance superhard layer, then:

a transition layer may be disposed between the shielding conductive layer and the display screen, the transition layer for improving a bonding rate of the conductive layer and the display screen. Wherein the transition layer can be made of silicon dioxide SiO₂The coating film may be formed of silicon dioxide SiO₂And titanium oxide TiO₂And forming a composite coating.

The anti-oxidation layer can be arranged above the shielding conductive layer, because the shielding conductive layer is mostly formed by a metal coating film, the metal is easy to oxidize, the conductive performance of the oxidized metal oxide is not good as that of the metal, and in this case, in order to effectively prevent the oxidation of the shielding conductive layer and maintain the conductive performance of the shielding conductive layer, the anti-oxidation layer can be arranged above the shielding conductive layer so as to reduce the oxidation probability of the shielding conductive layer.

The protective layer can be arranged above the anti-oxidation layer and is used for separating the first skin measuring point from the shielding conductive layer so as to prevent the first skin measuring point from being directly pressed on the shielding conductive layer and reduce the probability of abrasion of the shielding conductive layer. Wherein the protective layer may be made of silicon nitride Si₃N₄Or a coating of silicon carbide SiC, or a diamond-like film, a ceramic film, SiO₂The term "membrane" may also refer to a composite membrane system of two or more of the above. In the embodiment of the application, because the conductivity of the protective layer is poor, the thickness of the protective layer can be set to be less than 1 micrometer, so as to reduce the influence of the protective layer on the conductivity of the first electrode. Alternatively, in an alternative example, the thickness of the protective layer may be less than 500nm, in which case the protective layer is actually a very thin film, so that the electrical signal of the first skin measurement point can well penetrate through the film to the shielding conductive layer, which helps the shielding conductive layer to better acquire the electrical signal of the first skin measurement point.

In the embodiment of the present application, when the first electrode only includes the shielding conductive layer, the shielding conductive layer may be directly plated on the display screen, and when the first electrode further includes other coating layers, the first electrode may be formed by sequentially stacking the layers in the above manner.

EXAMPLE III

Fig. 5 schematically illustrates a structure of a first electrode provided in a third embodiment of the present application, in which the first electrode may be a mesh structure formed by conductive wires arranged in an interlaced manner, and the conductive wires arranged in the interlaced manner may cross to flow, so that the first electrode achieves a conductive function. The area where the grid structure is located may cover the entire display screen (as shown in a of fig. 5), or may cover a local area of the display screen, for example, a peripheral area of the display screen (as shown in b of fig. 5), or may cover a central area of the display screen (as shown in c of fig. 5). In order to allow good contact between the first skin measurement point and the first electrode when the area of the mesh structure covers a local area of the display screen, the area of the mesh structure is large enough, for example not less than 30 mm square.

In the embodiment of the present application, the mesh structure may have a specific texture circuit, and the texture circuit may be a regular geometric pattern or an irregular pattern. The mesh structure can be realized by using processes such as exposure and development, laser etching, transfer printing and the like, for example:

in one mode, a conductive film may be coated on a substrate, and then a mesh structure may be fabricated on the conductive film according to a specific texture circuit by etching or laser etching; alternatively, the first and second electrodes may be,

in another mode, the steps of gluing, exposing, developing and the like can be firstly carried out on the substrate, so that a texture circuit required by the mesh structure is photoetched, then the whole surface of the conductive film is covered on the substrate, and finally the redundant conductive film on the glue is removed while the glue is removed, so that the conductive film left on the texture circuit forms the mesh structure; alternatively, the first and second electrodes may be,

in still another way, the conductive paste may be sprayed into the specific texture using a transfer printing method or a spraying method to form a mesh structure.

In this embodiment, the conductive line may be a transparent conductive line (the material of the conductive line may refer to the first embodiment), or may be a shielding conductive line (i.e., an opaque conductive line or a semitransparent conductive line, and the material of the conductive line may refer to the second embodiment), in which case:

if the conductive line is a transparent conductive line, the line width of the conductive line can be set to be not less than 1 micron, and the wider line width can increase the conductivity of the conductive line because the transparent conductive line is invisible; alternatively, the first and second electrodes may be,

if the conductive line is a shielding conductive line, the line width of the conductive line is not more than 6 microns, so that the texture structure of the conductive line on the display screen is lightened as much as possible under the condition that the conductive performance of the first electrode is guaranteed, and the possibility that a user cannot see the conductive line is improved.

For example, in order to improve the scratch resistance of the first electrode, a protective layer may be further coated on the mesh structure, and the composition of the protective layer may refer to the description in the first embodiment or the second embodiment, and will not be described herein again.

The first to third embodiments describe specific structures of the first electrode, and the manner of electrically connecting the first electrode and the circuit component will be described in detail below. For the way of electrically connecting the second electrode and the circuit component, for example, the second electrode and the circuit component may be connected by a conductive wire, or a groove may be formed between the second electrode and the circuit component, and a conductive material is filled in the groove to conduct a circuit between the second electrode and the circuit component, which is not described in detail in this application.

Fig. 6 is a schematic diagram illustrating an electrical connection structure of the first electrode and the circuit component, as shown in fig. 6, the housing may further include a mounting middle frame, and the electrocardiograph detecting device may further include a first conductive connecting member, wherein the first conductive connecting member is used for mounting a side edge of the display screen on the mounting middle frame. Wherein the first end (T1) of the first conductive connection is in contact with the first electrode and the second end (T2) of the first conductive connection is connected to a circuit component (not shown in fig. 6), such that the first electrode is connectable to the circuit component via the first conductive connection. With this configuration, during electrocardiographic sensing, the first electrical signal from the first electrode can be transmitted along the first conductive connection from the terminal T1 to the terminal T2, and then from the terminal T2 to the circuit component. Alternatively, when power is supplied to the first electrode, the power output from the circuit component may be transmitted along the first conductive connection from terminal T2 to terminal T1 and then supplied to the first electrode from terminal T1. Through this kind of embodiment, first electrically conductive connecting piece can realize the electricity between first electrode and the circuit part when fixing the display screen at the assembly center, and two kinds of functions of fixed and electrically conductive can be realized simultaneously to first electrically conductive connecting piece promptly to can save part quantity, make electrocardio detection device's structure simpler.

It should be noted that the above example is only an alternative embodiment, and the embodiment is suitable for the first electrode covering the peripheral area of the display screen or the first electrode covering the whole display screen. In another alternative embodiment, if the first electrode covers the central area of the display screen, the T1 end of the first conductive connection may be connected to the first electrode through a conductive line, so that the first electrode can be electrically connected to the circuit component through the conductive line and the first conductive connection.

In one mode, as shown in fig. 7A, the upper surface and the side surface of the groove may be opened such that the upper surface of the conductive material is in contact with the lower surface of the first electrode and the side surface of the conductive material is in contact with the first conductive connecting member. Alternatively, as shown in fig. 7B, the upper surface, the lower surface, and the side surfaces of the groove may be opened such that the upper surface of the conductive material is in contact with the lower surface of the first electrode, and the side surfaces and the lower surface of the conductive material are in contact with the first conductive connecting member, respectively. With this embodiment, the bottom surface of the first electrode may be in contact with the side edge of the first conductive connection member through the conductive material in the groove, in addition to the side edge being in direct contact with the T1 end of the first conductive connection member, so that the contact area of the first electrode and the first conductive connection member is increased, and in this case, even if the position where the first electrode is in contact with the T1 end of the conductive connection member fails, and the first electrode cannot transmit the first electrical signal to the first conductive connection member through the position, the first electrode may transmit the first electrical signal to the first conductive connection member through the conductive material, thereby contributing to improving the stability of the electrical connection between the first electrode and the first conductive connection member.

In the embodiment of the present application, if the circuit component is disposed at a deep position inside the housing, the L2 end of the first conductive connecting member may not actually contact the circuit component, and in this case, the first conductive connecting member may also connect the circuit component through another conductive connecting member. There are many possible configurations of other conductive connectors, and two other configurations of conductive connectors are exemplary described below:

The first end of the second conductive connecting piece is contacted with the second end of the first conductive connecting piece, and the second end of the second conductive connecting piece is connected with the circuit component through a conductive wire. The second conductive connecting member may be a spring (as shown in fig. 8A), a conductive foam (as shown in fig. 8B), or other conductive materials, such as a conductive adhesive bonding member, conductive ink, or the like. Therefore, the first electric signal collected by the first electrode can be transmitted to the circuit component sequentially through the first conductive connecting piece and the second conductive connecting piece, and the electric energy output by the circuit component can also be provided to the first electrode sequentially through the second conductive connecting piece and the first conductive connecting piece.

FIG. 9 is a schematic diagram illustrating another electrical connection between the first electrically conductive connector and the circuit component, and as shown in FIG. 9, the electrocardiograph sensing device may further include a third electrically conductive connector disposed inside the housing. Wherein, the inner surface of the middle assembly frame may be coated with a conductive material such as a metal, the second end of the first conductive connecting member contacts a first position (position 1) of the inner surface of the middle assembly frame, the first end of the third conductive connecting member contacts a second position (position 2) of the inner surface of the middle assembly frame, and the second end of the third conductive connecting member contacts (or is connected to) the circuit part through a conductive wire. Therefore, the first electric signal collected by the first electrode can be transmitted to the circuit component sequentially through the first conductive connecting piece, the assembling middle frame and the second conductive connecting piece, and the electric energy output by the circuit component can also be provided to the first electrode sequentially through the second conductive connecting piece, the assembling middle frame and the first conductive connecting piece. The third conductive connecting member may be a conductive elastic sheet (as shown in fig. 9), or may be other conductive materials, such as conductive foam, conductive ink, or conductive adhesive welding member.
