Description

[0001] This application is a divisional application of the invention application with the application date of July 24, 2024, application number 202421766374.X, and invention title "Electrode Layer Assembly, Display Screen and Electronic Product". Technical Field

[0002] One or more embodiments of this specification relate to the field of near-field communication technology, and particularly to an electrode layer assembly, a display screen and an electronic product. Background Art

[0003] Near Field Communication (NFC) is a short-range high-frequency radio technology. By transmitting or receiving electromagnetic wave signals through an NFC antenna, non-contact identification and interconnection are achieved, and it is increasingly widely used in fields such as payment and security.

[0004] When applying NFC technology to various electronic products, there is often mutual interference between the NFC antenna and the original functional modules in the electronic product, such as the display screen, which affects the performance of each other. For example, the signal of the NFC antenna can cause abnormal display of the display screen, and the display screen can also interfere with the NFC antenna's reception or transmission of signals, resulting in a decline in NFC communication performance.

[0005] In this regard, in related technologies, a stacking form is usually adopted, and the NFC antenna is arranged on the back of the electronic product, that is, below the display screen, so as to keep a certain interval between the NFC antenna and the display screen to avoid mutual interference; however, such a stacking scheme will limit the appearance form and size of the product, which is not conducive to the thinning of electronic products. Utility Model Content

[0006] In order to balance the performance and appearance size of electronic products, one or more embodiments of this specification provide an electrode layer assembly, a display screen and an electronic product.

[0007] In a first aspect, one or more embodiments of this specification provide an electrode layer assembly integrated with an NFC antenna;

[0016] In one possible implementation, the multiple sub - electrodes include a plurality of ITO electrodes arranged in a dot matrix on the substrate;

[0017] The conductive wire is disposed within the gaps between the multiple ITO electrodes.

[0018] In one possible implementation, the substrate includes a glass substrate or a polymer compound substrate.

Since an electrode layer originally needs to be provided in an electronic product to implement related electrical control functions (such as display control, touch, etc.), setting the NFC antenna in the electrode layer of the electronic product can save the space occupied by separately setting the NFC antenna in the electronic product, and there is no need to space the NFC antenna and related components in the electronic product at a certain distance to avoid interference, thereby reducing the thickness and other appearance dimensions of the electronic product, which is beneficial to the thin and light design of the electronic product.

[0032] This embodiment can be widely applied to different display screens or electronic products.

[0040] The present application will be further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more definite.

[0041] The special term "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not have to be construed as superior or better than other embodiments. Although various aspects of the embodiments are shown in the drawings, unless otherwise specified, the drawings do not have to be drawn to scale.

[0042] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0043] In order to balance the performance and appearance size of electronic products, one or more embodiments of this specification provide an electrode layer assembly integrated with an NFC antenna. This electrode layer assembly can be an electrode layer for different control functions in an electronic product. For example, it can be an electrode layer for display control in a display module, or a touch electrode layer in a touch module.

[0044] Figure 1 Schematic diagram of an electrode layer assembly integrated with an NFC antenna provided for one or more embodiments of this specification.

[0045] Refer to Figure 1, the electrode layer assembly 10 includes a substrate 11, and a plurality of sub - electrodes 12 and an NFC antenna 13 disposed on the substrate.

[0046] Among them, the NFC antenna 13 is a coil - type antenna formed by surrounding at least one conductive wire, and the conductive wire is located in the gap between the plurality of sub - electrodes 12.

[0047] It can be seen that the electrode layer assembly provided by the embodiments of this specification can actually be regarded as a solution for implementing an NFC antenna based on an electrode layer. Integrating the NFC antenna into the electrode layer of an electronic product, that is, combining the NFC antenna and the electrode layer into one, so that the electrode layer assembly has both NFC communication function and conductive function. Since an electrode layer originally needs to be provided in an electronic product to implement related electrical control functions (such as display control, touch, etc.), setting the NFC antenna in the electrode layer of the electronic product can enable the electronic product to save the space occupied by separately setting the NFC antenna, and there is no need to space the NFC antenna and related components in the electronic product at a certain distance to avoid interference. The NFC function can be realized without increasing the size of the electronic product, which is beneficial to the thinning of the electronic product.

[0048] Optionally, in the electrode layer assembly 10, the material of the substrate 11 can be glass or a polymer compound (or plastic, resin), such as Polyethylene Terephthalate (PET), Polycarbonate (PC), etc.

[0049] The sub - electrode 12 can be a metal electrode, an Indium tin oxide (ITO) electrode, etc.; among them, the metal electrode used as the sub - electrode 12 can be made of metals such as copper and silver.

[0050] The conductive wire of the NFC antenna 13 can be an ITO wire, conductive ink, a metal wire, etc.; among them, the metal wire used as the NFC antenna 13 can be made of metals such as copper and silver.

[0051] Among them, the sub - electrode 12 and the NFC antenna 13 can be made of the same material, such as both made of ITO material. In some possible implementation manners, the sub - electrodes on the electrode layer assembly 10 can be ITO electrodes arranged in a dot - matrix pattern. As Figure 1 shown, the NFC antenna 13 can also be made of ITO material and is disposed in the gap between the dot - matrix ITO electrodes through processes such as sputtering and etching.

[0052] In addition, the sub - electrode 12 and the NFC antenna 13 can also be made of different materials, such as the sub - electrode 12 being an ITO electrode and the NFC antenna 13 using a metal wire.

[0053] In the specific preparation process of the above-mentioned electrode layer assembly 10, the sub-electrode 12 and the NFC antenna 13 can be integrally formed. For example, if both are made of ITO material, the preparation process is roughly as follows: A layer of ITO film is set on the substrate 11 through processes such as magnetron sputtering and coating, and then it is etched on the ITO film according to the composite pattern formed by the sub-electrode 12 and the NFC 13 through processes such as yellow light process, and then the electrode layer assembly 12 is obtained. Of course, the sub-electrode can also be prepared on the substrate first, and then the NFC antenna is prepared. That is, the specific preparation process of the electrode layer assembly provided in this embodiment can be determined in combination with actual conditions.

[0054] In this embodiment, shielding treatment can also be performed between the sub-electrode 12 and the NFC antenna 13 to avoid mutual interference between the two and improve their performance.

[0055] In a possible implementation, a grounded shielding wire can be provided between the conductive wire of the NFC antenna 13 and the sub-electrode 12.

[0056] Figure 2 is shown Figure 1 A partial enlarged schematic diagram of area A of the electrode layer assembly 10 in the figure. Refer to Figure 2 , shielding wires 14 can be provided on both sides of the conductive wire of the NFC antenna 13, and the shielding wires 14 can be parallel to the conductive wire of the NFC antenna 13.

[0057] The above-mentioned shielding wire 14 can specifically adopt materials such as ITO, metal, and conductive ink.

[0058] Of course, in other embodiments, shielding between the NFC antenna and the sub-electrode can also be achieved through other common shielding methods, and this embodiment will not list them one by one.

[0059] As can be seen from the above description, in this embodiment, the NFC antenna is integrated on the electrode layer commonly used in electronic products, and grounding and shielding treatments are performed between the NFC antenna and the original sub-electrode on the electrode layer to ensure that the two do not interfere with each other, realizing a good NFC antenna integration solution. There is no need to keep a certain distance between the NFC antenna and other components in the electronic product to avoid interference, which can make the appearance and size of the corresponding electronic product more flexible.

[0060] In a possible implementation, any point on the conductive wire of the NFC antenna 13 can be used as the grounding point; when applied to a specific module or electronic product, the grounding point can be connected to the common ground of the corresponding module or electronic product through a lead wire.

[0061] Figure 1In the illustrated embodiment, the conductive wire forming the NFC antenna 13 is an uninterrupted and complete conductive wire. In other possible implementation manners, the NFC antenna 13 may also be composed of a plurality of conductive wires, which will be elaborated in detail below in conjunction with Figure 2 for elaboration.

[0062] In different application scenarios, the shapes, sizes, and arrangement manners of the sub-electrodes 12 in the electrode layer are diverse. In addition to Figure 1 the dot matrix arrangement shown, where the area of each sub-electrode is relatively small, the sub-electrodes may also be large-area blocks, strips, etc., as shown in Figure 3 shown; this results in the NFC antenna 13 located in the same layer as the sub-electrodes may intersect with the sub-electrodes in some areas, as shown in Figure 3 the intersection area B shown.

[0063] For the above situation, the intersection between the sub-electrode 12 and the NFC antenna in the intersection area B can be achieved without electrical connection in the direction perpendicular to the substrate through a bridging method. Specifically, when preparing the conductive wire of the NFC antenna 13, it can be disconnected at the intersection area B, that is, a plurality of conductive wires are formed; in this intersection area B, an insulating pad 131 and a connecting portion 132 are sequentially stacked on the upper layer of the sub-electrode 12. The connecting portion 132 serves as a "bridge" to connect the two conductive wires on both sides of the intersection area B. At the same time, since the insulating pad 131 is located between the connecting portion 132 and the sub-electrode 12, the insulation between the sub-electrode 12 and the NFC antenna 13 in the intersection area B is achieved. In this way, although when viewed from the direction perpendicular to the substrate, the NFC antenna 13 and the sub-electrode 12 still intersect at the intersection area B, there is no electrical connection, ensuring the independent operation of the two without mutual influence.

[0064] In other possible implementation manners, the connection between two adjacent conductive wires of the NFC antenna 13 can also be achieved through a via hole at the intersection area B, while being insulated from the sub-electrode 12. For details, reference can be made to the related technology, and this embodiment will not be elaborated further.

[0065] In addition, if in actual application, according to the control requirements of the electrode layer, it is necessary to connect two or more sub-electrodes, and the connecting wire will intersect with the NFC antenna, the bridging or via hole method described above can also be used to prevent the connecting wire between the sub-electrodes from having an electrical connection with the NFC antenna.

[0066] From the above elaboration, based on the inventive concept of this embodiment, the NFC antenna can be integrated on the electrode layer with any sub-electrode layout manner, combining with the NFC antenna into one without affecting the original functions of the electrode layer, which is beneficial to the thinning of related modules or electronic products.

[0067] In a possible implementation, in the above electrode layer assembly 10, the conductive wires forming the NFC antenna 13 are arranged in a surrounding manner within a preset NFC induction area of the substrate 11; the preset NFC induction area is an effective induction area designed according to the NFC function configuration requirements of relevant modules or electronic products. In different application scenarios, the size and position of the preset NFC induction area relative to the substrate may be different.

[0068] For example, the preset NFC induction area may be the entire area of the substrate, and the conductive wires of the NFC antenna 13 may be arranged in a surrounding manner along the edge of the substrate as shown in Figure 1 the figure. Another example is that the preset NFC induction area may also be the upper half area C of the substrate, as shown in Figure 4 the figure, and the conductive wires of the NFC antenna 13 may be arranged in a surrounding manner along the edge of the upper half area C.

[0069] As can be seen from the above description, by adopting this embodiment, the size and position of the NFC induction area can be set arbitrarily according to requirements, so as to ensure the radiation range of the NFC antenna and improve the performance of the NFC antenna.

[0070] In a possible implementation, the above electrode layer assembly 10 may be a display control electrode layer of a display screen; correspondingly, the sub - electrodes 12 may be connected to the display main board of the display screen through a flexible printed circuit (FPC) or the like.

[0071] In a possible implementation, the above electrode layer assembly 10 may also be a touch control electrode layer of a touch control module; correspondingly, the sub - electrodes 12 may be connected to the touch control main board of the touch control module through an FPC board or the like.

[0072] In addition, in this embodiment, both ends of the conductive wires forming the NFC antenna 13 may be respectively connected to an NFC control board to implement the NFC function. Its working process is as follows: when acting as an information receiving party, the NFC antenna senses an external NFC signal (electromagnetic wave signal) and converts it into an electrical signal for transmission to the NFC control board. The NFC control board determines the information contained in the received NFC signal through analog - to - digital conversion, digital signal processing and identification, etc.; conversely, when acting as an information sending party, the NFC control board converts the information to be sent through digital - to - analog conversion to form a corresponding electrical signal for transmission to the NFC antenna, and then the electrical signal is converted into an electromagnetic wave signal by the NFC antenna and radiated out.

[0073] It can be seen that the electrode layer assembly integrating the NFC antenna provided in this embodiment has a wide range of applications and can be an effective solution for realizing the appearance and function optimization of various electronic products.

[0074] Based on the same inventive concept, one or more embodiments of this specification also provide a display screen. As Figure 5 shown, the display screen 200 may include a display module 210 and a display main board 220, and the two may be connected through a PFC board or the like. The display main board 220 is used to perform display control on the display module 210 to make it display corresponding images.

[0075] Among them, the display module 210 may include upper and lower electrode layers. Any one of the electrode layers may adopt the electrode layer assembly 10 integrated with the NFC antenna described in the foregoing embodiments. At the same time, the display screen 200 further includes an NFC control board 230, which is connected to the NFC antenna integrated in the electrode layer, so that the display screen 200 has both display and NFC functions.

[0076] In addition, the substrate 11 of the electrode layer assembly 10 applied to the display module 210 may adopt a transparent material, such as glass, PET, etc.; at the same time, the sub-electrodes and the NFC antenna also adopt transparent ITO materials to ensure the light transmittance and screen brightness of the display module 210.

[0077] In a possible implementation manner, for Figure 5 the shown display screen 200, the NFC control board 230 may be disposed on the back surface of the display module 210.

[0078] In practical applications, based on different display principles, the display module 210 includes different types, such as a liquid crystal (Liquid Crystal Display, LCD) display module, an organic light-emitting semiconductor (Organic Light-Emitting Diode, OLED) display module, etc.

[0079] In a possible implementation manner, as Figure 6 shown in (a) of, the LCD display module 210a mainly includes a liquid crystal layer a1 and a first electrode layer a2 and a second electrode layer a3 on its upper and lower sides. The display main board 220 is connected to the two electrode layers a2 and a3. By applying appropriate voltage signals to the two electrode layers a2 and a3, the liquid crystal molecules in the liquid crystal layer a1 are arranged in a specific direction under the action of an electric field, so as to control the light emitted by the display screen, that is, to control the display pattern. For the LCD display module 210a shown in (a) of Figure 6 , any one of its first electrode layer a2 and second electrode layer a3 may adopt the electrode layer assembly 10 described in the foregoing embodiments.

[0080] In a possible implementation manner, as Figure 6The OLED display module 210b shown in (b) mainly includes: an anode layer b1 and a cathode layer b2 connected to the display main board 220, and a plurality of functional layers composed of organic molecules located between b1 and b2, such as a hole transport layer b3, a light-emitting layer b4, an electron transport layer b5, etc. The light-emitting principle of the OLED display module 210b is as follows: Under the drive of the voltage output by the display main board, holes and electrons are respectively injected into the hole transport layer b3 and the electron transport layer b5 from the anode layer b1 and the cathode layer b2. After being transported through the two layers of b3 and b5, the holes and electrons meet in the light-emitting layer b4, generating energy excitons, thereby exciting the light-emitting molecules to generate visible light. For Figure 6 For the OLED display module 210b shown in (b) of the [Chinese text], its light-emitting surface is generally the side where the anode layer b1 is located, and the cathode layer b2 is the backlight surface. Therefore, the anode layer b1 usually adopts an ITO electrode layer with high light transmittance, and the cathode layer b2 can adopt a metal electrode layer; either the anode layer b1 or the cathode layer b2 can adopt the electrode layer assembly 10 described in the foregoing embodiment. To ensure the NFC signal induction intensity, the anode layer b1 close to the outside of the display screen can adopt the structure shown in the electrode layer assembly 10.

[0081] As can be seen from the above description, the display screen described in this embodiment can adopt a display module with any structure, and any electrode layer in the display module can adopt the electrode layer assembly integrated with the NFC antenna described above, that is, a display screen integrated with an NFC antenna or an NFC module is realized, so that the display screen has both display and NFC functions. On the premise of ensuring the display and NFC performance, the device integration degree is improved, and the appearance size design of the display screen has higher flexibility.

[0082] Based on the same inventive concept, one or more embodiments of this specification also provide an electronic product. Any electrode layer in this electronic product can adopt the electrode layer assembly integrated with the NFC antenna in the foregoing embodiment. For example, if this electronic product has a touch control module, one touch control electrode layer of this touch control module can adopt the electrode layer assembly 10 integrated with the NFC antenna described above.

[0083] In addition, this electronic product has a display screen, and this display screen can adopt the display screen 200 integrated with an NFC antenna or an NFC module described in the foregoing embodiment.

[0084] In addition, in some optional implementation manners, this electronic product may further include: a mobile communication module, an input unit, an audio processor, a power supply, etc., which can be specifically configured according to the functional requirements of the electronic product.

[0085] Optionally, the above-mentioned electronic product may be a mobile phone, a tablet computer, a smart watch, etc. By adopting the electrode layer assembly 10 integrated with the NFC antenna or the display screen 200 integrated with the NFC antenna or the NFC module, while ensuring the NFC performance, there is no need to reserve space for accommodating the NFC component in the electronic product to implement the NFC function, making the appearance and size design of the electronic product more flexible.
