When the NFC technology is applied to various electronic products, the NFC antenna and the original functional modules in the electronic products, such as a display screen, are often mutually interfered, and the performance of the functional modules is affected. For example, the signal from the NFC antenna may cause the display screen to display abnormally, and the display screen may interfere with the NFC antenna to receive or transmit the signal, resulting in a decrease in NFC communication performance.

In the related art, in this regard, a stacking manner is generally adopted, and the NFC antenna is disposed on the back of the electronic product, that is, below the display screen, so that a certain interval is kept between the NFC antenna and the display screen, so as to avoid mutual interference; such stacking scheme can limit the appearance and size of the product, which is unfavorable for the light and thin electronic product.

Detailed Description

The application is further described in detail below by means of the figures and examples. The features and advantages of the present application will become more apparent from the description.

The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

In addition, the technical features described below in the different embodiments of the present application may be combined with each other as long as they do not collide with each other.

In order to achieve both performance and external dimensions of the electronic product, one or more embodiments of the present disclosure provide an electrode layer assembly of an integrated NFC antenna. The electrode layer assembly can be an electrode layer for different control functions in an electronic product, for example, the electrode layer for performing display control in a display module, and also can be a touch electrode layer in a touch module.

Fig. 1 is a schematic structural diagram of an electrode layer assembly of an integrated NFC antenna according to one or more embodiments of the present disclosure.

Referring to fig. 1, the electrode layer assembly 10 includes a substrate 11, and a plurality of sub-electrodes 12 and NFC antennas 13 disposed on the substrate.

The NFC antenna 13 is a coil antenna formed by winding at least one conductive wire, and the conductive wire is located in the gaps of the plurality of sub-electrodes 12.

It can be seen that the electrode layer assembly provided in the embodiments of the present disclosure may be actually considered as an implementation scheme of an NFC antenna based on an electrode layer, and the NFC antenna is integrated in the electrode layer of an electronic product, that is, the NFC antenna and the electrode layer are combined into one, so that the electrode layer assembly has an NFC communication function and a conductive function. Because the electrode layer is required to be arranged in the electronic product originally to realize the related electric control function (such as display control, touch control and the like), the NFC antenna is arranged in the electrode layer of the electronic product, so that the electronic product can save the space occupied by independently arranging the NFC antenna, and the NFC antenna and related components in the electronic product are not required to be separated by a certain distance to avoid interference, the NFC function is realized on the premise of not increasing the size of the electronic product, and the thinning of the electronic product is facilitated.

Alternatively, in the electrode layer assembly 10, the substrate 11 may be made of glass, or may be made of a polymer compound (or plastic, resin), such as polyethylene terephthalate (Polyethylene Terephthalate, PET), polycarbonate (PC), or the like.

The sub-electrode 12 may be a metal electrode, an Indium Tin Oxide (ITO) electrode, or the like; the metal electrode used as the sub-electrode 12 may be made of a metal material such as copper or silver.

The conductive wire of the NFC antenna 13 may be an ITO wire, conductive ink, or a metal wire; the metal wire used as the NFC antenna 13 may be made of a metal material such as copper or silver.

The sub-electrodes 12 and the NFC antenna 13 may be made of the same material, for example, ITO. In some possible implementations, the sub-electrodes on the electrode layer assembly 10 may be ITO electrodes arranged in a lattice, as shown in fig. 1, and the NFC antenna 13 may also be made of ITO material, and disposed in the gaps of the lattice ITO electrodes through sputtering, etching, and other processes.

In addition, the sub-electrode 12 and the NFC antenna 13 may be made of different materials, for example, the sub-electrode 12 is an ITO electrode, and the NFC antenna 13 is a metal wire.

In a specific preparation process of the electrode layer assembly 10, the sub-electrode 12 and the NFC antenna 13 may be integrally formed, for example, both are made of ITO, and the preparation process is approximately as follows: an ITO film is provided on the substrate 11 by a magnetron sputtering, coating, or the like, and then etched on the ITO film by a yellow light process or the like according to a composite pattern formed by the sub-electrodes 12 and the NFC13, to obtain the electrode layer assembly 12. Naturally, the sub-electrode may be first prepared on the substrate, and then the NFC antenna may be prepared. That is, the specific manufacturing process of the electrode layer assembly provided in this embodiment may be determined in combination with actual conditions.

In this embodiment, shielding treatment can be further performed between the sub-electrode 12 and the NFC antenna 13, so as to avoid mutual interference between the sub-electrode and the NFC antenna and improve performance of the sub-electrode and the NFC antenna.

In a possible implementation, a grounded shielding wire may be provided between the conductive wire forming the NFC antenna 13 and the sub-electrode 12.

Fig. 2 shows an enlarged partial schematic view of region a of the electrode layer assembly 10 of fig. 1. Referring to fig. 2, shielding wires 14 may be disposed at both sides of the conductive wire of the NFC antenna 13, and the shielding wires 14 may be parallel to the conductive wire of the NFC antenna 13.

The shielding wire 14 may be made of ITO, metal, conductive ink, or the like.

Of course, in other embodiments, the shielding between the NFC antenna and the sub-electrode may be implemented by other common shielding methods, which are not listed in this embodiment.

As can be seen from the above description, in this embodiment, the NFC antenna is integrated on the electrode layer commonly used in the electronic product, and the grounding and shielding processes are performed between the NFC antenna and the original sub-electrode on the electrode layer, so that the two are not interfered with each other, a good NFC antenna integration scheme is achieved, and the NFC antenna and other components in the electronic product do not need to be kept at a certain interval to avoid interference, so that the appearance and the size of the corresponding electronic product are more flexible.

In a possible implementation, any point on the conductive line of the NFC antenna 13 may be used as a ground point; when applied to a specific module or electronic product, the ground point can be commonly connected with the corresponding module or electronic product through a lead.

In the embodiment shown in fig. 1, the conductive line surrounding the NFC antenna 13 is an uninterrupted complete conductive line. In other possible implementations, the NFC antenna 13 may also be formed by combining a plurality of conductive wires, which is described in detail below in connection with fig. 2.

In different application scenarios, the shape, size and arrangement modes of the sub-electrodes 12 in the electrode layer are various, and besides the dot matrix arrangement shown in fig. 1 and the smaller area of each sub-electrode, the sub-electrodes may also be in the shape of blocks, strips, etc. with larger area, as shown in fig. 3; this results in an NFC antenna 13 located in the same layer as the sub-electrode, possibly intersecting the sub-electrode in a partial area, as shown in fig. 3 at an intersection area B.

For the above case, the sub-electrode 12 and the NFC antenna in the intersection region B may intersect in the direction perpendicular to the substrate but are not electrically connected by a bridge manner. Specifically, in preparing the conductive lines of the NFC antenna 13, it is possible to break them at the intersection region B, i.e., to form a plurality of conductive lines; in the intersection area B, the insulating pad 131 and the connecting portion 132 are stacked in sequence on the upper layer of the sub-electrode 12, the connecting portion 132 serves as a bridge to connect two conductive wires on two sides of the intersection area B, and meanwhile, the insulating pad 131 is located between the connecting portion 132 and the sub-electrode 12 to insulate the sub-electrode 12 and the NFC antenna 13 in the intersection area B. In this way, although the NFC antenna 13 and the sub-electrode 12 still intersect at the intersection area B when seen from the direction perpendicular to the substrate, there is no electrical connection, ensuring that the two work independently and do not affect each other.

In other possible implementations, the connection between two adjacent conductive wires of the NFC antenna 13 may also be implemented by a via at the intersection area B, and may be insulated from the sub-electrode 12, which may be specifically referred to the related art, and this embodiment will not be described in detail.

In addition, if in practical application, according to the control requirement of the electrode layer, it is necessary to connect some two or more sub-electrodes, and the connection line will generate an intersection point with the NFC antenna, or the connection line between the sub-electrodes and the NFC antenna may be prevented from being electrically connected by the bypass or via manner.

As can be seen from the above description, based on the inventive concept of the present embodiment, the NFC antenna can be integrated on the electrode layer with any sub-electrode layout mode, and the NFC antenna can be integrated with the NFC antenna without affecting the original functions of the electrode layer, which is beneficial to the light and thin of the related module or electronic product.

In a possible implementation manner, in the electrode layer assembly 10, the conductive wire forming the NFC antenna 13 is disposed around the substrate 11 in a preset NFC sensing area; the preset NFC sensing area is an effective sensing area designed according to NFC function configuration requirements of related modules or electronic products. In different application scenarios, the size and the position of the preset NFC sensing area relative to the substrate may be different.

For example, the preset NFC sensing area may be the entire area of the substrate, and the conductive wire of the NFC antenna 13 may be disposed around the edge of the substrate as shown in fig. 1. As another example, the preset NFC sensing area may also be the upper half area C of the substrate, as shown in fig. 4, and the conductive wire of the NFC antenna 13 may be disposed around the edge of the upper half area C.

It can be seen from the above description that, by adopting the embodiment, the size and the position of the NFC sensing area can be set arbitrarily according to the requirement, so as to ensure the radiation range of the NFC antenna and improve the performance of the NFC antenna.

In one possible implementation, the electrode layer assembly 10 may be a display control electrode layer of a display screen; accordingly, the sub-electrodes 12 may be connected to a display main board of the display screen through a flexible circuit board (Flexible Printed Circuit, FPC) or the like.

In one possible implementation, the electrode layer assembly 10 may also be a touch electrode layer of a touch module; correspondingly, the sub-electrodes 12 may be connected to a touch motherboard of the touch module through an FPC board or the like.

In addition, in this embodiment, two ends of the conductive wire forming the NFC antenna 13 may be connected to the NFC control board respectively, so as to implement an NFC function. The working flow is as follows: when the NFC antenna is used as an information receiver, the NFC antenna senses an external NFC signal (electromagnetic wave signal) and converts the NFC signal into an electric signal to be transmitted to the NFC control board, and the NFC control board determines information contained in the received NFC signal through analog-to-digital conversion, digital signal processing identification and the like; on the contrary, when the NFC control board is used as an information sender, information to be sent is subjected to digital-to-analog conversion to form corresponding electric signals, the corresponding electric signals are transmitted to the NFC antenna, and the electric signals are converted into electromagnetic wave signals through the NFC antenna to be radiated.

Therefore, the electrode layer assembly of the integrated NFC antenna provided in this embodiment is widely applied, and can be used as an effective scheme for optimizing the appearance and functions of various electronic products.

One or more embodiments of the present specification also provide a display screen based on the same inventive concept. As shown in fig. 5, the display screen 200 may include a display module 210 and a display main board 220, which may be connected by a PFC board or the like, and the display main board 220 is used for performing display control on the display module 210 so as to display a corresponding image.

In addition, the substrate 11 of the electrode layer assembly 10 applied to the display module 210 may be made of transparent materials, such as glass, PET, etc.; meanwhile, the sub-electrodes and the NFC antenna are made of transparent ITO materials, so that the light transmittance and the screen brightness of the display module 210 are ensured.

In one possible implementation, nfc control board 230 may be disposed on the back of display module 210 for display screen 200 shown in fig. 5.

In practical applications, the display module 210 includes different types of display modules, such as a Liquid crystal (Liquid CRYSTAL DISPLAY, LCD) display module, an Organic Light-Emitting Diode (OLED) display module, and so on, based on different display principles.

In a possible implementation manner, as shown in (a) of fig. 6, 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 the upper and lower sides thereof, where the display main board 220 is connected to the two electrode layers a2 and a3, and 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 emergent light of the display screen, that is, control the display pattern. As for the LCD display module 210a shown in fig. 6 (a), any one of the first electrode layer a2 and the second electrode layer a3 may be used as the electrode layer assembly 10 described in the above embodiment.

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 transmission layer b3 and the electron transmission layer b5 from the anode layer b1 and the cathode layer b2, and the holes and the electrons meet at the light-emitting layer b4 through the transmission of the two layers b3 and b5, so that energy excitons are generated, and light-emitting molecules are excited to generate visible light. For the OLED display module 210b shown in fig. 6 (b), the light emitting surface is generally the surface on which the anode layer b1 is located, and the cathode layer b2 is a backlight surface, so that the anode layer b1 is usually an ITO electrode layer with high light transmittance, and the cathode layer b2 may be a metal electrode layer; any one of the anode layer b1 and the cathode layer b2 may employ the electrode layer assembly 10 described in the above embodiment.
