Patent Description:
Handheld wireless communication devices (e.g. cell phones, smart watches, etc.) are becoming increasingly functional, and market requirements for device appearance and wireless communication performance are also becoming more and more demanding. In the era of the 5th generation mobile communications (<NUM>), since both millimeter-waves (mm-waves) and non-millimeter waves (non-millimeter-waves) are involved, types and numbers of antennas in a handheld wireless communication device are increasing. In addition, functions of near field communication (NFC) are becoming increasingly popular, so NFC coils also have been provided in more and more handheld wireless communication devices.

Meanwhile, screen-to-body ratios of the handheld wireless communication devices are becoming higher and higher. Therefore, since overall sizes of the devices cannot be significantly increased, arranging wireless communication modules in display panels is a critical technology trend in foreseeable future. However, internal spaces of the display panels are limited and have optical requirements, so how to arrange the wireless communication modules in the display panels has become an important technical problem to be solved urgently.

<CIT> provides a multi-band frame antenna used for LTE, MIMO, and other frequency bands. The frame antenna includes a conductive block and a metallic frame with no gaps or discontinuities. The conductive block functions as a system ground and has at least one electronic component mounted on the surface. The outer perimeter of the metallic frame surrounds the conductive block, and there is a gap between the metallic frame and the conductive block. One or more antenna feeds are routed across the gap, between the metallic frame and the conductive block. One or more connections can be made across the gap, and at least one electronic element connects the conductive block to the metallic frame.

<CIT> provides an apparatus including: a first conductive antenna track, extending between a first end and a second end and defining a loop shape, the first conductive antenna track including a first feed point adjacent to the first end and configured to couple to radio frequency circuitry; and a second conductive antenna track coupled to the first conductive antenna track at a first location in proximity to the first feed point, and at a second location between the first end and the second end of the first conductive antenna track, to form a first closed loop configured to resonate in a first operational frequency band.

An antenna device and an electronic device having the antenna device are provided. The antenna device includes a conductive film member including mesh grid areas formed by transparent wires and electrodes, and a radiation pattern path formed between the mesh grid areas. The electronic device includes a display including a touch panel, wherein the touch panel includes a conductive film member including mesh grid areas formed by transparent wires and electrodes, and a radiation pattern path formed between the mesh grid areas.

International patent application <CIT> provides an antenna system, including a first antenna, a second antenna, a ground plane, and a resonant isolator located proximate to the first antenna and the second antenna. The resonant isolator is coupled to the ground plane at or proximate to one current null point created by a first antenna and at or proximate to a second current null point created by a second antenna, and is configured to isolate the first antenna from the second antenna at a resonance. In some cases, the resonant isolator may include at least two conductive portions that may be substantially parallel to one another. The resonant isolator may also include an active tuning element that may change the resonance at which the resonant isolator de-couples the two antennas. In some cases, each of the antennas may be a capacitively-coupled compound loop antenna.

Features, objects and advantages of the present application will be clearer from the detailed description of following reference drawings of non-limited embodiments, wherein the same or similar reference numerals and/or letters mean the same or similar features.

Features and exemplary embodiments of various aspects of the present application are described in detail below. In the following detailed description, numerous specific details are presented to provide a thorough understanding of the present application. However, it will be apparent for those skilled in the art that the present application may be implemented without some of these specific details. The following description of the embodiments is merely for providing a better understanding of the present application by illustrating examples of the present application. In the drawings and the following description, at least some of well know structures and techniques have not been shown to avoid unnecessary obscurity of the present application. In addition, size of some structures may be exaggerates for clarity. Furthermore, the features, structures, or characteristics described below may be combined in one or more embodiments by any suitable manner.

With the development of display technology and wireless communication technology, screen-to-body ratios of display apparatuses in devices with wireless communication functions are continually increasing, and types and numbers of transmission modules used to achieve wireless communication in the devices are also increasing. For example, in the era of 5th generation mobile communications, spectrum of wireless communication covers both millimeter waves and non-millimeter waves. Therefore, a wireless communication device with <NUM> mm-wave functions, such as a mobile phone, not only may have provided therein a first type antenna that can be used for millimeter waves, but also usually may have provided therein wireless communication modules that can be used for non-millimeter waves (such as those used for <NUM>, <NUM>, WLAN (wireless local area network), BT (Bluetooth), GNSS (global navigation satellite system), etc.). At the same time, NFC (Near Field Communication) is also becoming increasingly popular, and therefore, more and more mobile phones also have NFC coils provided therein.

However, the higher the screen-to-body ratio of the display apparatus in the wireless communication device is, the more liable it is to limit the positions where the wireless communication modules can be positioned, and the more liable it is to block the wireless communication modules when the device is being used (for example, the device is being held by hand or placed on a metal table), which results in significant degradation of antenna performance and affects user's wireless experience. In view of the above, it is contemplated that the wireless communication modules are integrated in the display apparatus of the electronic device, for example, in a design manner of Antenna-on-Display (AoD), which has become a possible direction of development for antenna designs in electronic devices.

In some embodiments, with reference to <FIG>, take the wireless communication device <NUM> being a mobile phone as an example, wireless communication modules integrated in a display apparatus <NUM> of a mobile phone may include a <NUM> millimeter-wave antenna <NUM>, a WiFiBT antenna <NUM>, a Long Term Evolution (LTE) antenna <NUM>, an NFC coil <NUM>, and a <NUM> non-millimeter-wave antenna <NUM>. Typically, the <NUM> millimeter-wave antenna <NUM>, the WiFiBT antenna <NUM>, the LTE antenna <NUM>, the NFC coil <NUM> and the <NUM> non-millimeter-wave antenna <NUM> are arranged in the display apparatus <NUM> independently from one another. However, an internal space of the display apparatus <NUM> is limited, and how to arrange the wireless communication modules in the limited space and ensure desired optical and touch effects of the display panel has become a technical problem to be solved urgently.

In order to solve the problem above, the present application is presented. For a better understanding of the present application, the wireless communication structure, the display panel and the wireless communication device of embodiments of the present application are described in detail below with reference to <FIG>.

Reference is made to <FIG>, which is a schematic structural view of a display panel according to a first embodiment of the present application.

As shown in <FIG>, the display panel provided by an embodiment of the present application includes a wireless communication structure. The wireless communication structure may be configured in various manners. As shown in <FIG>, the wireless communication structure provided by an embodiment of the first aspect of the present application includes a loop structure <NUM> and antenna <NUM>. The loop structure <NUM> includes a first connection end <NUM>, a second connection end <NUM>, and a coil body <NUM>. At least a part of the coil body <NUM> is connected between the first connection end <NUM> and the second connection end <NUM>. The antenna <NUM> is connected to the coil body <NUM>.

In the wireless communication structure provided by an embodiment of the present application, the wireless communication structure includes the loop structure <NUM> and the antenna <NUM>. The loop structure <NUM> includes the first connection end <NUM>, the second connection end <NUM> and the coil body <NUM>, and is configured to transmit and/or receive wireless signals on the coil body <NUM> through the first connection end <NUM> and the second connection end <NUM>. Since the antenna <NUM> is connected to the coil body <NUM> of the loop structure <NUM>, at least a part of the coil body <NUM> may transmit and/or receive wireless signals of the loop structure <NUM> and wireless signals of the antenna <NUM> at the same time. An overall area occupied by the loop structure <NUM> and the antenna <NUM> can be reduced, so that two or more antennas <NUM> may be arranged in a limited space, and thus the influence on the optical performance of the display screen can be reduced, so that a desired optical performance of the display screen is ensured. Besides, a patterning process of the antenna <NUM> is simplified, thereby improving the manufacturing efficiency of the antenna <NUM> and reducing the manufacturing cost.

Optionally, the antenna includes a feeding portion and a radiating portion, either of which may be connected to the coil body <NUM>. Alternatively, both the feeding portion and the radiating portion are connected to the coil body <NUM>. In an embodiment of the present application, the radiating portion of the antenna <NUM> being connected to the coil body <NUM> is taken as an example for illustration.

As an optional embodiment, with further reference to <FIG>, when the wireless communication structure is used in a display panel, the display panel further includes a touch layer <NUM>. The touch layer <NUM> is a film layer including a touch structure. The loop structure <NUM> and the antenna <NUM> being arranged on the touch layer <NUM> may specifically mean that the touch structure, the loop structure <NUM> and the antenna <NUM> are arranged on a same film layer. The touch layer <NUM> includes mesh-shaped metal wires, which are illustrated as light-colored mesh-shaped lines in <FIG>. When the loop structure <NUM> and the antenna <NUM> are arranged in the touch layer <NUM>, at least one loop structure <NUM> is connected to the antenna <NUM>. This can reduce the number of cutting points of the mesh-shaped metal wires, thus improving degradation of touch performance and experience due to expansion of touch blind areas caused by the disposition of the antenna <NUM> in the touch layer <NUM>, that is, a desired touch performance of the display screen can be ensured. Additionally, at least one loop structure <NUM> is connected to the antenna <NUM>, which can reduce the number of cutting points of the mesh-shaped metal wires, so that patterns formed by mesh-shaped metal wires in different areas tend to be uniform, which can also improve optical effect of the display panel.

Optionally, the loop structure <NUM> is a looped coil, which can be configured in various manners. For example, the loop structure <NUM> includes at least one of a NFC coil, a wireless power charging (WPC) coil, a LTE coil, a global positioning GNSS coil, a WLAN coil, a frequency modulation (FM) coil, and the like. The NFC coil, the WPC coil, the LTE coil, the GNSS coil, the WLAN coil, the FM coil and the like may each be configured as a looped coil, to facilitate the connection of the antenna <NUM> therewith.

Optionally, the loop structure <NUM> includes at least one of the NFC coil and the WPC coil. Because a size of the loop structure <NUM> including the NFC coil and/or the WPC coil is generally large. For example, the loop structure <NUM> including the NFC coil and/or the WPC coil are arranged close to and around edges of the display panel to facilitate the connection of the antenna <NUM> with the loop structure100 including the NFC coil and/or the WPC coil, and the antenna <NUM> is able to be arranged closer to the edges of the display panel. As such, the degradation of the optical and touch effects of the display panel caused by the antenna <NUM> can be insignificant, and a feeding path of the antenna <NUM> can be short, so the feeding loss can be low and a desired radiation performance of antenna <NUM> is achieved.

Optionally, the loop structure <NUM> is configured to transmit and/or receive wireless signals in non-millimeter-wave band. Transmitting and/or receiving wireless signals in non-millimeter-wave band refers to receiving and/or sending wireless signals in non-millimeter-wave band, that is, to transmit and/or receive means to receive and/or send herein.

For example, the loop structure <NUM> is a coupled coil configured to transmit the wireless signals in the non-millimeter-wave band through coupling. The loop structure <NUM> is configured to transmit signals through coupling, and the antenna <NUM> is configured to transmit signals through radiation, that is, the wireless communication structure may be configured to implement two different manners of wireless signal transmission.

Optionally, the loop structure <NUM> and the antenna <NUM> are each configured for wireless communication and have a corresponding frequency band.

For example, the loop structure <NUM> is the NFC coil, of which a communication frequency band is, for example, <NUM>. Alternatively, the loop structure <NUM> is the WPC coil, and a communication frequency band of a commonly used WPC coil is, for example, higher than or equal to <NUM>. The NFC coil and the WPC coil are coupled coils used in non-mobile wireless communication (because currently the NFC coil and the WPC coil need to be geologically referenced to a counterpart communication apparatus).

The loop structure <NUM> may include a coupling portion and a feeding portion. For example, the coil body <NUM> is the coupling portion of the loop structure <NUM>. The first connection end <NUM> and the second connection end <NUM> are the feeding portion of the loop structure <NUM>. The loop structure <NUM> may be configured for short-distance point-to-point wireless communication.

Optionally, the loop structure <NUM> may further include the FM coil. A common FM frequency band is <NUM> to <NUM>, and the FM coil is applied to long-distance non-mobile wireless communication.

There are various manners to set the number of antennas <NUM>. As shown in <FIG>, the number of antennas <NUM> may be one.

Alternatively, reference is made to <FIG>, which is a schematic structural view of a display panel according to a second embodiment of the first aspect. The structure of the embodiment illustrated in <FIG> is partially the same as the structure of the embodiment illustrated in <FIG>, which will not be described in detail here, and differences therebetween will be described below. In addition, the following description herein will be directed to differences between various embodiments associated with respective drawings.

As shown in <FIG>, a plurality of antennas <NUM> may be included, and the plurality of antennas <NUM> are arranged in a spaced manner on an extending path of the coil body <NUM>.

The antenna <NUM> may be arranged in various manners. In some optional embodiments, with further reference to <FIG> and <FIG>, the antenna <NUM> includes a non-millimeter-wave antenna <NUM>. The non-millimeter-wave antenna <NUM> includes a non-millimeter-wave radiating portion <NUM> and a non-millimeter-wave feeding portion <NUM>. The non-millimeter-wave radiating portion <NUM> is connected to the coil body <NUM>.

In these optional embodiments, the non-millimeter-wave radiating portion <NUM> is connected to the coil body <NUM>, and thus the non-millimeter-wave radiating portion <NUM> and the coil body <NUM> are connected to each other, so that the number of cutting points of the mesh-shaped metal wires can be reduced. This can ensure a desired optical performance of the display screen and simplify patterning process of the antenna <NUM>, thereby improving the manufacturing efficiency of the antenna <NUM> and reducing the manufacturing cost.

For example, frequencies of non-millimeter waves commonly used in mobile wireless communication are higher than <NUM> and lower than <NUM>, that is, the non-millimeter-wave antenna <NUM> refers to an antenna configured to transmit and/or receive wireless signals having frequencies higher than <NUM> and lower than <NUM>. The coil body <NUM> is configured to transmit wireless signals through coupling, and frequencies of wireless signals transmitted by the coil body <NUM> through coupling may be lower than <NUM>.

Optionally, the non-millimeter-wave antenna <NUM> is an antenna configured for mobile wireless communication. The non-millimeter-wave antenna <NUM> herein generally refers to the non-millimeter-wave antenna <NUM> configured for mobile wireless communication and the non-millimeter-wave antenna <NUM> configured for mobile communication (including a cellular antenna, a WLAN antenna, a Bluetooth antenna, a GNSS antenna and the like for <NUM> and the previous generations).

Optionally, the non-millimeter-wave radiating portion <NUM> may have various shapes. For example, as shown in <FIG> and <FIG>, the non-millimeter-wave radiating portion <NUM> is rectangular. In other embodiments, as shown in <FIG>, the non-millimeter-wave radiating portion <NUM> may be special shaped. When the non-millimeter-wave radiating portion is connected to the coil body <NUM>, in order to control the influence of the loop structure <NUM> on the non-millimeter-wave antenna <NUM>, various configurations may be used to block non-millimeter-wave currents on the loop structure <NUM>.

An impedance of a conductor includes a resistance and a reactance.

Resistance = ρ (L/A), where ρ is a resistivity of the conductor, L is a length of the conductor, and A is a current distribution area corresponding to currents applied to the conductor. Given that intrinsic electrical and structural size parameters of the conductor are of constant values, when a signal frequency increases, a distribution area of a current in the conductor will decrease due to the skin effect (that is, the higher the frequency of the signal is, the more likely it is to concentrate the corresponding current on a thin layer near a surface of the conductor), that is, A will decrease, resulting in an increase in the resistance.

Since reactance = inductive reactance - capacitive reactance, the reactance and the inductive reactance are positively correlated. Inductive reactance = jwL, where w is an angular frequency and w=2πf, where f is a frequency, and L is an inductance; therefore, when the signal frequency increases, the inductive reactance increases. In addition, due to the skin effect mentioned above, an inductance corresponding to the high-frequency signal will also increase, which further increases the inductive reactance.

To sum up, when a frequency of a signal increases, flow of its corresponding current in the conductor will be blocked. Therefore, under same conductor conditions, a current corresponding to a high-frequency signal is more likely to be blocked than a current corresponding to a low-frequency signal. In addition, when a width of the conductor becomes smaller, the inductance of the conductor will increase, and therefore, the inductive reactance will further increase, so that flow of the current corresponding to the high-frequency signal will be further blocked. That is, by adjusting the size of the conductor, currents corresponding to different frequency signals can be desirably blocked or allowed to pass through.

When the loop structure <NUM> includes the NFC coil, a frequency band of wireless signals in millimeter-wave band transmitted and/or received by the millimeter-wave antenna unit <NUM> is higher than the NFC frequency band. Therefore, under same conductor conditions, the millimeter-wave currents corresponding to the frequencies of the wireless signals in the millimeter-wave band are more liable to be blocked and less liable to be allowed to pass through compared to the currents corresponding to the NFC frequency band. Therefore, by adjusting the size of the coil body <NUM>, the millimeter-wave currents can be desirably blocked and the currents corresponding to the NFC frequency band can be desirably allowed to pass through.

When the loop structure <NUM> includes the NFC coil and the antenna <NUM> includes the non-millimeter-wave antenna <NUM>, the frequencies of the wireless signals in the non-millimeter-wave band transmitted and/or received by the non-millimeter-wave antenna <NUM> are higher than the NFC frequency band. Therefore, under same conductor conditions, the non-millimeter-wave currents corresponding to the frequencies of the wireless signals in the non-millimeter-wave band are more liable to be blocked and less liable to be allowed to pass through compared to the currents corresponding to the NFC frequency band. Therefore, by adjusting the size of the coil body <NUM>, the non-millimeter-wave currents can be desirably blocked and the currents corresponding to the NFC frequency band can be desirably allowed to pass through.

In some embodiments, as shown in <FIG>, a width of at least a part of the non-millimeter-wave radiating portion <NUM> is different from a line width of at least a part of the coil body <NUM>, so that at least a part of the coil body <NUM> can allow the wireless signal currents transmitted and/or received by the loop structure <NUM> to pass through and block the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM>. The non-millimeter-wave currents refer to currents of the frequencies corresponding to wireless signals in non-millimeter-wave band transmitted and/or received by the non-millimeter-wave antenna <NUM>, and wireless signal currents transmitted and/or received by the loop structure <NUM> refer to currents corresponding to the frequencies of wireless signals transmitted and/or received by the loop structure <NUM>.

In these optional embodiments, the line width of at least a part of the non-millimeter-wave radiating portion <NUM> is different from the line width of at least a part of the coil body <NUM>, so that the currents for transmitting the signals of the frequency band corresponding to the non-millimeter-wave antenna <NUM> can pass through the non-millimeter-wave radiating portion <NUM>, but cannot pass through the coil body <NUM>. Therefore, signal currents of the non-millimeter-wave antenna <NUM> and the loop structure <NUM> can be isolated from each other.

That is, in these embodiments, by appropriately configuring the line width of the coil body <NUM> and the line width of the non-millimeter-wave radiating portion <NUM>, the currents corresponding to the frequencies of wireless signals transmitted and/or received by the non-millimeter-wave antenna <NUM> and the loop structure <NUM> can be isolated from each other.

Optionally, a line width of at least a part of the coil body <NUM> is not greater than a line width of the non-millimeter-wave radiating portion <NUM>.

In these optional embodiments, because the line width of at least a part of the coil body <NUM> is relatively small, at least the part of the coil body <NUM> has a relatively high impedance. Therefore, at least the part of the coil body <NUM> has a desired filtering and blocking effect on the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM>. Therefore, in an embodiment of the present application, by configuring the line width of at least a part of the coil body <NUM> as being relatively small, currents of wireless signals transmitted and/or received by the non-millimeter-wave antenna <NUM> and the loop structure <NUM> can be isolated from each other.

In some other optional embodiments, as shown in <FIG>, a first blocking portion <NUM> is arranged on the coil body <NUM>. The first blocking portion <NUM> is configured to allow the wireless signal currents transmitted and/or received by the loop structure <NUM> to pass through, and block the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM>.

In an embodiment of the present application, by providing the coil body <NUM> with the first blocking portion <NUM>, the wireless signal currents transmitted and/or received by the loop structure <NUM> can pass through the first blocking portion <NUM>, and the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM> are blocked by the first blocking portion <NUM>, which can achieve the isolation between the wireless signal currents transmitted and/or received by the non-millimeter-wave antenna <NUM> and the loop structure <NUM>.

In the embodiments mentioned above, when the first blocking portion <NUM> is configured to achieve the isolation between the currents transmitted and/or received by the non-millimeter-wave antenna <NUM> and the loop structure <NUM>, optionally, as shown in <FIG>, the number of the first blocking portion <NUM> may be one. One first blocking portion <NUM> may be arranged on a side of the non-millimeter-wave antenna <NUM> close to or away from the first connection end <NUM>.

For example, as shown in <FIG>, one first blocking portion <NUM> may be arranged between at least one non-millimeter-wave antenna <NUM> and the second connection end <NUM>. In these optional embodiments, the currents of the non-millimeter-wave feeding portion <NUM> may flow to the first blocking portion <NUM> or to the first connection end <NUM>, so that the non-millimeter-wave antenna <NUM> can transmit and/or receive non-millimeter-wave wireless signals in various frequency bands.

Alternatively, in some other embodiments, as shown in <FIG>, the number of the first blocking portions <NUM> may be two or more, and two or more first blocking portions <NUM> are arranged on both sides of the non-millimeter-wave antenna <NUM>.

In these optional embodiments, two or more first blocking portions <NUM> include a first blocking portion 141a positioned on a side of the non-millimeter-wave antenna <NUM> close to the first connection end <NUM> and a first blocking portion 141b positioned on a side of the non-millimeter-wave antenna <NUM> away from the first connection end <NUM>. The currents flowing out of the non-millimeter-wave feeding portion <NUM> can flow to the first blocking portion 141a and the first blocking portion 141b, so that the non-millimeter-wave antenna <NUM> can transmit and/or receive the wireless signals in various frequency bands. In addition, by appropriately arranging the positions of the first blocking portion 141a and the first blocking portion 141b, the frequency band corresponding to the non-millimeter-wave antenna <NUM> can be controlled, so as to achieve the purpose of precisely controlling the frequency bands of wireless signals received by the non-millimeter-wave antenna <NUM>.

In some optional embodiments, as shown in <FIG>, the number of the non-millimeter-wave antennas <NUM> is two or more, and two or more non-millimeter-wave antennas <NUM> are arranged in a spaced manner on an extending path of the coil body <NUM>.

When the number of the non-millimeter-wave antennas <NUM> is two or more, the number of the first blocking portions <NUM> may be one, two or more. The first blocking portion <NUM> may be arranged between the non-millimeter-wave antenna <NUM> and the first connection end <NUM> and/or between the non-millimeter-wave antenna <NUM> and the second connection end <NUM>, the first blocking portion <NUM> may also be arranged between non-millimeter-wave radiating portions <NUM> of two adjacent non-millimeter-wave antennas <NUM>.

Optionally, in order to achieve the isolation of the wireless signal currents transmitted and/or received by the non-millimeter-wave antenna <NUM> and the loop structure <NUM>, the line width of the first blocking portion <NUM> is different from the line width of the coil body <NUM>, so that the wireless signal currents transmitted and/or received by the loop structure <NUM> can pass through the first blocking portion <NUM>, but the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM> cannot pass through the first blocking portion <NUM>.

Optionally, as shown in <FIG>, the non-millimeter-wave radiating portion <NUM> includes a non-millimeter-wave wire, and the line width of the first blocking portion <NUM> is smaller than the width of the non-millimeter-wave wire in the non-millimeter-wave radiating portion <NUM>, so that the first blocking portion <NUM> can block the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM>. In these optional embodiments, the line width of the first blocking portion <NUM> is relatively small, so that the first blocking portion <NUM> has a relatively high impedance. Therefore, the first blocking portion <NUM> has a desired filtering and blocking effect on the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM>.

With reference to <FIG>, in some optional embodiments, the antenna <NUM> further includes a millimeter-wave antenna unit <NUM> connected to the coil body <NUM>.

In these optional embodiments, the millimeter-wave antenna unit <NUM> is connected to the coil body <NUM>, and the millimeter-wave antenna unit <NUM> and the coil body <NUM> are connected to each other. This can ensure a desired optical performance of the display screen and simplify patterning process of the antenna <NUM>, thereby improving the manufacturing efficiency of the antenna <NUM> and reducing the manufacturing cost.

When the antenna <NUM> and the loop structure <NUM> are arranged in the touch layer <NUM>, the millimeter-wave antenna unit <NUM> and the coil body <NUM> are connected to each other, which can reduce the cutting points of the mesh-shaped metal wiring and ensure a desired touch effect of the touch layer <NUM> at the same time.

Optionally, the millimeter-wave antenna unit <NUM> may have various shapes, for example, the shape of the millimeter-wave antenna unit <NUM> may be a square, a diamond, or the like.

Optionally, with reference to <FIG>, two or more millimeter-wave-antenna units <NUM> form a millimeter-wave antenna array <NUM> in combination. In an embodiment of the present application, the number of millimeter-wave antenna units <NUM> is two or more, and two or more millimeter-wave antenna units <NUM> are arranged adjacently or in an array to form the millimeter-wave antenna array <NUM>, which can improve the antenna gain and compensate for the large radiation path loss, and can achieve the effect of beam scanning to cover a wide space to reduce the wireless communication blind areas and achieve a desired user wireless experience.

Optionally, transmission frequencies of the millimeter-wave antenna array <NUM> are different form the transmission frequencies of non-millimeter-wave antenna <NUM>. For example, frequencies of millimeter waves commonly used in the mobile wireless communication are higher than <NUM>, that is, the millimeter-wave antenna array <NUM> refers to an antenna array that transmits and/or receives wireless signals with frequencies higher than <NUM>.

Optionally, the millimeter-wave antenna array <NUM> and the non-millimeter-wave antenna <NUM> are antennas configured for mobile wireless communication.

When the antenna <NUM> of the wireless communication structure includes the millimeter-wave antenna array <NUM> and the non-millimeter-wave antennas <NUM>, the millimeter-wave antenna array <NUM> and the non-millimeter-wave antennas <NUM> may be arranged in various manners.

Optionally, the coil body <NUM> includes a first connection segment <NUM> and a second connection segment <NUM>. The first connection segment <NUM> is connected between the first connection end <NUM> and the antenna <NUM>. The second connection segment <NUM> is connected between the second connection end <NUM> and the antenna <NUM>. When two or more millimeter-wave antenna units <NUM> form the millimeter-wave antenna array <NUM> in combination, the coil body <NUM> further includes a third connection segment <NUM>. The third connection segment <NUM> is connected between two adjacent millimeter-wave antenna units <NUM> in a same millimeter-wave antenna array <NUM>.

The first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> may be arranged in various manners. For example, the first connection segment <NUM> may include one wire, or the first connection segment <NUM> may include multiple wires arranged side by side, or the first connection segment <NUM> may include multiple wires arranged side by side and bridge wires connecting the wires arranged side by side. Likewise, the second connection segment <NUM> and/or the third connection segment <NUM> may include a wire, or the second connection segment <NUM> and/or the third connection segment <NUM> may include multiple wires arranged side by side, or the second connection segment <NUM> and/or the third connection segment <NUM> may include multiple wires arranged side by side and bridge wires connecting the wires arranged side by side.

In some optional embodiments, as shown in <FIG>, the millimeter-wave antenna unit <NUM> and the non-millimeter-wave radiating portion <NUM> are spaced apart from each other on the extending path of the coil body <NUM>, to avoid a significant degradation of wireless communication quality because of the antennas being blocked (for example, by a human hand, a human head and metals, etc.) at the same time. This can also increase the spatial coverage of the antenna radiation beams, which reduces wireless communication blind areas. In addition, the mutual negative influences between the millimeter-wave antenna array <NUM> and the non-millimeter-wave antenna <NUM> or between multiple non-millimeter-wave antennas can be reduced to improve the quality of wireless communication.

When the loop structure <NUM> includes the NFC coil and the antenna <NUM> includes non-millimeter-wave antenna <NUM> and a millimeter-wave antenna array <NUM>, the frequencies of the millimeter-wave wireless signals transmitted and/or received by the millimeter-wave antenna array <NUM> are higher than the frequencies of the non-millimeter-wave wireless signals transmitted and/or received by the non-millimeter-wave antenna <NUM>, and the frequencies of the non-millimeter-wave wireless signals transmitted and/or received by the non-millimeter-wave antenna <NUM> are higher than the NFC frequency band. Therefore, under same conductor conditions, the millimeter-wave currents corresponding to the frequencies of the millimeter-wave wireless signals are more liable to be blocked and less liable to pass through compared to the currents corresponding to the frequencies of the non-millimeter-wave wireless signals, and the non-millimeter-wave currents corresponding to the frequencies of the non-millimeter-wave wireless signals are more liable to be blocked and less liable to pass through compared to the currents corresponding to the NFC frequency band. Therefore, by adjusting the size of the coil body <NUM>, the millimeter-wave currents can be desirably blocked and the non-millimeter-wave currents and the currents corresponding to the NFC frequency band can desirably pass through, or, by adjusting the size of the coil body <NUM>, the millimeter-wave currents and the non-millimeter-wave currents can be desirably blocked, and the currents corresponding to the NFC frequency band can desirably pass through.

When the millimeter-wave antenna unit <NUM> and the non-millimeter-wave radiating portion <NUM> are arranged on the coil body <NUM> in a spaced manner, the currents of wireless signals transmitted and/or received by the millimeter-wave antenna array <NUM> and the non-millimeter-wave antennas <NUM> can be isolated through various manners.

Optionally, the line width of at least a part of the coil body <NUM> is not greater than the width of the millimeter-wave antenna unit <NUM>. That is, the line width of at least a part of the coil body <NUM> is relatively small and the impedance of at least a part of the coil body <NUM> is relatively high. The millimeter-wave currents can be desirably blocked, so that the coil body <NUM> may have a desired filtering and blocking effect on the millimeter-wave currents transmitted and/or received by the millimeter-wave antenna array <NUM> to ensure a desired performance of the millimeter-wave antenna array <NUM>. That is, in an embodiment, by appropriately designing the line width of the coil body <NUM>, the coil body <NUM> can block the millimeter-wave currents.

Optionally, the line width of the first connection segment <NUM> is not greater than the sum of the line widths of millimeter-wave wires in the millimeter-wave antenna unit <NUM>. As shown in <FIG>, when the first connection segment <NUM> extends along a first direction X, the width direction of the first connection segment <NUM> and the millimeter-wave wire is a second direction Y; and when the first connection segment <NUM> extends along the second direction Y, the width direction of the first connection segment <NUM> and the millimeter-wave wire is the first direction X.

In an embodiment of the present application, the line width of the first connection segment <NUM> is relatively small, so that the first connection segment <NUM> has a relatively high impedance. Therefore, the first connection segment <NUM> may have a desired filtering and blocking effect on the non-millimeter-wave currents and the millimeter-wave currents. However, the first connection segment <NUM> has a desired passing effect on the currents of the NFC frequency band. Therefore, in an embodiment of the present application, the currents of the loop structure <NUM> can desirably pass through the first connection segment <NUM>, but the non-millimeter-wave currents and the millimeter-wave currents are significantly blocked by the first connection segment <NUM>.

Optionally, the line width of the first connection segment <NUM> is not greater than the sum of the line widths of the millimeter-wave wires in the millimeter-wave antenna units <NUM>. As shown in <FIG>, when the second connection segment <NUM> extends along the first direction X, the width direction of the second connection segment <NUM> and the millimeter-wave wire is the second direction Y; when the second connection segment <NUM> extends along the second direction Y, the width direction of the second connection segment <NUM> and the millimeter-wave wire is the first direction X.

As mentioned above, the line width of the second connection segment <NUM> is relatively small, so that the millimeter-wave currents can be desirably blocked and the non-millimeter-wave currents can desirably pass through, that is, the blocking of the millimeter-wave currents can be desirably achieved by the second connection segment <NUM>, which can ensure a desired performance of the millimeter-wave antenna array <NUM> and the millimeter-wave antenna unit <NUM>, and does not significantly affect other non-millimeter-wave currents and the currents of the NFC frequency band.

The number of the third connection segments <NUM> may be set in various manners. As shown in <FIG>, the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> may include one wire. Alternatively, as shown in <FIG>, the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> may include two or more wires.

Optionally, as shown in <FIG>, when the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> include one wire, the line width of one wire in the third connection segments <NUM> is not greater than the sum of the line widths of the millimeter-wave wires in the millimeter-wave antenna unit <NUM>. As shown in <FIG>, when the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> include two or more wires, the sum of the line widths of two or more wires in the third connection segment <NUM> is not greater than the sum of the line widths of the millimeter-wave wires in the millimeter-wave antenna unit <NUM>. As shown in <FIG>, when the first direction X is perpendicular to the second direction Y, the third connection segment <NUM> extends along the second direction Y, and the width direction of the third connection segment <NUM> and the millimeter-wave wire is the first direction X. In some other embodiments, when the third connection segment <NUM> extends along the first direction X, the width direction of the third connection segment <NUM> and the millimeter-wave wire is the second direction Y.

In an embodiment of the present application, the line width of the third connection segment <NUM> is relatively small, so that the third connection segments <NUM> have a relatively high impedance. Therefore, the third connection segments <NUM> may have a desired filtering and blocking effect on the millimeter-wave currents. However, the third connection segment <NUM> can have a desired passing effect on non-millimeter-wave frequencies of mobile communication in <NUM> and the previous generations, WLAN or BT and the like, and the currents of the NFC frequency band and the like. The third connection segment <NUM> may have various shapes, as shown in <FIG>, the shape of the third connection segment <NUM> may be a straight line, that is, the third connection segment <NUM> extends along one direction. Alternatively, as shown in <FIG>, the third connection segment <NUM> may be in the shape of a folded line, that is, the third connection segment <NUM> extends along a bending path. Alternatively, the third connection segment <NUM> may be in the shape of an arc. Alternatively, the third connection segment <NUM> are formed by a combination of at least two of a straight line, a folded line, and an arc.

Alternatively, a line width of at least a part of the coil body <NUM> is not greater than a line width of the non-millimeter-wave radiating portion <NUM>. That is, the line width of at least a part of at least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segments <NUM> is not greater than the width of the non-millimeter-wave radiating portion <NUM>. Optionally, the line width of at least a part of at least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segments <NUM> is not greater than the width of the non-millimeter-wave wire in the non-millimeter-wave radiating portion <NUM>.

For example, the line width of at least a part of the first connection segment <NUM> is not greater than the width of the non-millimeter-wave radiating portion <NUM>. When the non-millimeter-wave radiating portion <NUM> is in the shape of block, the non-millimeter-wave radiating portion <NUM> can be understood as including one non-millimeter-wave wire. When the non-millimeter-wave radiating portion <NUM> include multiple non-millimeter-wave wires, that the line width of at least a part of the first connection segment <NUM> is not greater than the width of the non-millimeter-wave radiating portion <NUM> means that the line width of at least a part of the first connection segment <NUM> is not greater than the sum of the widths of the multiple non-millimeter-wave wires in the non-millimeter-wave radiating portion <NUM>.

Optionally, the line widths of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segments133 are each set to be not greater than the line width of the non-millimeter-wave wire. In this way, the non-millimeter-wave currents can be significantly blocked by the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM>, so that the independence of each non-millimeter-wave radiating portion <NUM> in the millimeter-wave antenna array <NUM> can be desirably ensured, thereby ensuring the performance of the millimeter-wave antenna array <NUM>.

Optionally, at least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segments <NUM> can block the non-millimeter-wave currents. At least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segments <NUM> can block the millimeter-wave currents. So that neither the non-millimeter-wave currents nor the millimeter-wave currents can pass through at least a part of the coil body <NUM>. Even when the millimeter-wave antenna array <NUM> and the non-millimeter-wave radiating portion <NUM> of the non-millimeter-wave antenna <NUM> are both connected to the coil body <NUM>, the wireless signal currents of the non-millimeter-wave antenna <NUM> and the millimeter-wave antenna array <NUM> can be blocked on the loop structure <NUM>, so that a desired performance of the non-millimeter-wave antenna <NUM> and the millimeter-wave antenna array <NUM> can be designed and ensured.

In some optional embodiments, with further reference to <FIG>, the millimeter-wave antenna unit <NUM> and the non-millimeter-wave radiating portion <NUM> may be arranged on the coil body <NUM> in a spaced manner. The first blocking portion <NUM> are arranged on the coil body <NUM>, to block the non-millimeter-wave currents and the millimeter-wave currents in the coil body <NUM>.

Optionally, with reference to <FIG>, the number of antennas <NUM> is two or more, and the first connection segment <NUM> is connected between one of the antennas <NUM> ( for example, the non-millimeter-wave antenna <NUM>) and the first connection end <NUM>. The second connection segment <NUM> includes a first sub-segment 132a and a second sub-segment 132b. The first sub-segment 132a is connected between two adjacent antennas <NUM> (for example, the first sub-segment 132a is connected between the adjacent non-millimeter-wave antenna <NUM> and the millimeter-wave antenna array <NUM>). The second sub-segment 132b is connected between another antenna <NUM> (for example, the millimeter-wave antenna array <NUM>) and the second connection end <NUM>. The first sub-segment 132a is configured to implement the connection between two adjacent antennas <NUM>, and the second sub-segment 132b is configured to implement the connection between the antenna <NUM> and the second connection end <NUM>. That is, the second connection segment <NUM> is divided into multiple segments, and part of the second connection segment <NUM> (for example, the first sub-segment 132a) is configured to implement the connection between two adjacent antennas <NUM>, and part of the second connection segment <NUM> (for example, the second sub-segment 132b) is configured to implement the connection between the antenna <NUM> and the second connection end <NUM>.

As shown in <FIG>, the antennas <NUM> can be divided into three groups. Two of the three groups of antennas <NUM> are arranged opposite to each other along the first direction X, that is, the two groups of antennas <NUM> are arranged on edges of two opposite sides of the display panel along the first direction X, respectively (the two groups of antennas <NUM> are not necessarily on exactly the same position relative to the respective edges of the display panel). Another one of the three groups of antennas <NUM> are arranged opposite to the first connection end <NUM> and the second connection end <NUM> along the second direction Y, so that the first connection end <NUM>, the second connection end <NUM> and the three groups of antennas <NUM> are distributed around the periphery of the display panel in a spaced manner, and the antennas <NUM> are distributed at different positions of the display panel. When a user uses different gestures to operate the display panel, there can always be at least one antenna <NUM> in a position that is not blocked by the user, so the stability of the antennas <NUM> for transmitting and/or receiving the wireless signals can be improved, and a desired user's wireless experience can be ensured.

In some other optional embodiments, as shown in <FIG>, the first connection end <NUM>, the second connection end <NUM>, and the antennas <NUM> may be arranged along the first direction X in a spaced manner. That is the first connection end <NUM> and the second connection end <NUM> are arranged by the side of one of the antennas <NUM>.

In still some other embodiments, with further reference to <FIG>, when the antenna <NUM> of the wireless communication structure include the millimeter-wave antenna unit <NUM> and the non-millimeter-wave antenna <NUM>, at least one millimeter-wave antenna unit <NUM> is reused as at least a part of the non-millimeter-wave radiating portion <NUM>.

In these optional embodiments, wiring structure of the wireless communication structure can be further simplified, and when the wireless communication structure is arranged in the display panel, the display effect of the display panel can be improved. Additionally, at least one millimeter-wave antenna unit <NUM> and at least a part of the non-millimeter-wave radiating portion <NUM> may be reused as each other, which can reduce the distribution area of the wireless communication structure, so that more antennas <NUM> can be arranged in a small space.

That at least one millimeter-wave antenna unit <NUM> is reused as at least a part of the non-millimeter-wave radiating portion <NUM> may means that one millimeter-wave antenna unit <NUM> is reused as at least a part of the non-millimeter-wave radiating portion <NUM>, or at least two adjacent millimeter-wave antenna units <NUM> are connected by the third connection segment <NUM> and reused as at least a part of the non-millimeter-wave radiating portion <NUM>. That at least two adjacent millimeter-wave antenna units <NUM> are connected by the third connection segment <NUM> and reused as at least a part of the non-millimeter-wave antenna <NUM> means that at least two adjacent millimeter-wave antenna units <NUM>, when connected by the third connection segment <NUM>, can have the function of the non-millimeter-wave radiating portion <NUM> and be configured to transmit and/or receive the non-millimeter-wave wireless signals.

When at least one millimeter-wave antenna unit <NUM> is reused at least a part of the non-millimeter-wave radiating portion <NUM>, the at least one millimeter-wave antenna unit <NUM> can be connected to the non-millimeter-wave feeding portion <NUM>, for example, the at least one millimeter-wave antenna unit <NUM> can be connected to the non-millimeter-wave feeding portion <NUM> by a part of the coil body <NUM>. So that the at least two adjacent millimeter-wave antenna units <NUM> are able to be connected to a radio frequency integrated circuit of the non-millimeter-wave antenna <NUM>, the function of the non-millimeter-wave antenna <NUM> can be achieved.

When at least two adjacent millimeter-wave antenna units <NUM> are connected by the third connection segment <NUM> and reused as at least a part of the non-millimeter-wave radiating portion <NUM>, at least two adjacent millimeter-wave antenna units <NUM> may be connected in series or in parallel with each other and reused as at least a part of the non-millimeter-wave radiating portion <NUM>.

In these optional embodiments, the reusing of at least a part of the non-millimeter-wave antenna <NUM>, at least a part of the millimeter-wave antenna array <NUM> and at least a part of the loop structure <NUM> can further reduce the area occupied by the various type of antennas <NUM> and simplify disposition pattern of the various types of antennas <NUM>. Therefore, the cutting points of mesh-shaped metal wiring can be reduced, and desired display performance and touch performance of the display panel can be ensured.

When at least one millimeter-wave antenna unit <NUM> and at least a part of the non-millimeter-wave radiating portion <NUM> are reused as each other, the non-millimeter-wave radiating portion <NUM> and the non-millimeter-wave feeding portion <NUM> may be connected to each other in various manners.

The first connection wire <NUM> may include one or multiple wires.

Optionally, the coil body <NUM> is divided into a first connection segment <NUM>, a second connection segment <NUM> and third connection segment <NUM>. The first connection segment <NUM> is positioned between the millimeter-wave antenna unit <NUM> and the first connection end <NUM>. As shown in <FIG>, when the non-millimeter-wave radiating portion <NUM> is positioned on a side of the millimeter-wave antenna unit <NUM> close to the first connection end <NUM>, the first connection wire <NUM> may be part of the first connection segment <NUM>. In other embodiments, the second connection segment <NUM> is positioned between the millimeter-wave antenna unit <NUM> and the second connection end <NUM>, when the non-millimeter-wave radiating portion <NUM> is positioned on a side of the millimeter-wave antenna unit <NUM> close to the second connection end <NUM>, the first connection wire <NUM> may be part of the second connection segment <NUM>.

Optionally, as shown in <FIG>, second blocking portions <NUM> are arranged on the coil body <NUM> and configured to allowed the wireless signal currents transmitted and/or received by the loop structure <NUM> and the non-millimeter-wave currents of the wireless signals transmitted and/or received by the non-millimeter-wave antennas <NUM> to pass through, and block the millimeter-wave currents transmitted and/or received by the millimeter-wave antenna unit <NUM>, and the line width of the second blocking portion <NUM> is greater than the line width of the first blocking portion <NUM>.

In these optional embodiments, by arranging the second blocking portion <NUM> on the coil body <NUM>, millimeter-wave currents can be desirably blocked, and a desired performance of the millimeter-wave antenna unit <NUM> can be designed and ensured.

In addition, non-millimeter-wave currents can pass through the second blocking portion <NUM>. As shown in <FIG>, when two millimeter-wave antenna units <NUM> are reused as at least part of the non-millimeter-wave radiating portion <NUM>, a second blocking portion <NUM> is arranged between two millimeter-wave antenna units <NUM>, where the second blocking portion <NUM> does not block non-millimeter-wave currents.

The second blocking portion <NUM> may be configured in various manners. For example, the second blocking portion <NUM> may be configured by changing the width of at least part of the coil body <NUM> (that is, by changing the thickness of the coil body <NUM>), to achieve the goal of blocking millimeter-wave currents. The user can configure the position, width, length, shape, layer numbers and the number of the second blocking portions <NUM> according to the frequencies of the wireless signals in the non-millimeter-wave band transmitted and/or received by the non-millimeter-wave antennas <NUM> and the frequencies of the wireless signals transmitted and/or received by the loop structure <NUM> in actual use, to block the millimeter-wave currents, thus achieving the design of targeted operating frequency of the millimeter waves.

Optionally, as shown in <FIG>, in order to illustrate the positions of the second blocking portions <NUM> more clearly, the width of the second blocking portion <NUM> is set to be greater than the width of the coil body <NUM>.

The second blocking portion <NUM> may be arranged in various positions. Optionally, the number of the second blocking portions <NUM> is two or more, and two or more second blocking portions <NUM> are positioned on both sides of the millimeter-wave antenna unit <NUM> to block millimeter-wave currents, thus implementing the design of the targeted operating frequency of the millimeter waves.

When the first blocking portion <NUM> and the second blocking portion <NUM> are arranged on the coil body <NUM>, the first blocking portion <NUM> and the second blocking portion <NUM> may be arranged in various positions. For example, the first blocking portion <NUM> and/or the second blocking portion <NUM> may be arranged between adjacent millimeter-wave antenna units <NUM> in the same millimeter-wave antenna array <NUM>.

The first blocking portion <NUM> and the second blocking portion <NUM> may be arranged on any one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM>.

In some other optional embodiments, as shown in <FIG>, the first blocking portion <NUM> may be arranged on the third connection segment <NUM>.

For example, as shown in <FIG>, two or more millimeter-wave antenna units <NUM> in the millimeter-wave antenna array <NUM> are reused as the non-millimeter-wave antenna <NUM> in <FIG>, and the first blocking portion <NUM> may be arranged between the two or more millimeter-wave antenna units <NUM> in the millimeter-wave antenna array <NUM> and other millimeter-wave antenna units <NUM>.

Optionally, in <FIG>, for example, the first blocking portion <NUM> includes a first sub-blocking portion 141a, a second sub-blocking portion 141b, and a third sub-blocking portion 141c. Currents flowing out of the non-millimeter-wave feeding portion <NUM> may flow to the first sub-blocking portion 141a, or currents flowing out of the non-millimeter-wave feeding portion <NUM> may flow to the second sub-blocking portion 141b.

Optionally, the non-millimeter-wave antenna <NUM> in <FIG> is a non-millimeter-wave antenna <NUM> corresponding to multiple frequencies, that is, the currents flowing out of the non-millimeter-wave feeding portion <NUM> to the first sub-blocking portion 141a and the second sub-blocking portion 141b are currents with frequencies within the frequencies corresponding to the non-millimeter-wave antenna <NUM>.

Alternatively, the non-millimeter-wave antenna <NUM> in <FIG> is a non-millimeter-wave antenna <NUM> covering a single targeted frequency band. For example, when the currents flowing out of the non-millimeter-wave feeding portion <NUM> flow to the second sub-blocking portion 141b, the currents are currents with frequencies within the targeted frequencies corresponding to the non-millimeter-wave antenna <NUM>. Appropriately designing a wire path between the non-millimeter-wave feeding portion <NUM> and the first sub-blocking portion 141a may have beneficial effects on the performance of the targeted frequencies corresponding to the non-millimeter-wave antenna <NUM>.

For example, the millimeter-wave antenna array <NUM> in <FIG> includes four millimeter-wave antenna units <NUM>. Two adjacent millimeter-wave antenna units <NUM> are reused as the non-millimeter-wave radiating portion <NUM>, then the first blocking portion <NUM> may be arranged in the middle of the four millimeter-wave antenna units <NUM>. That is, two or more millimeter-wave antenna units <NUM> in a same millimeter-wave antenna array <NUM> are divided into two groups, and each group includes two millimeter-wave antenna units <NUM>.

In other embodiments, as shown in <FIG>, when at least one millimeter-wave antenna unit <NUM> is reused as the non-millimeter-wave radiating portion <NUM>, the first blocking portion <NUM> in the millimeter-wave antenna array <NUM> may be arranged between three millimeter-wave antenna units <NUM> and another millimeter-wave antenna unit <NUM>.

The arrangement in which the line width of the second blocking portion <NUM> is not greater than the width of the millimeter-wave antenna unit <NUM> is the same as the arrangement in which the first blocking portion <NUM> is not greater than the width of the millimeter-wave antenna unit <NUM>, which will not be repeated here.

Optionally, as shown in <FIG>, when at least one millimeter-wave antenna unit <NUM> is reused as at least a part of the non-millimeter-wave radiating portion <NUM>, the currents flowing out of the non-millimeter-wave feeding portion <NUM> may flow to the non-millimeter-wave radiating portion <NUM> formed through reusing the millimeter-wave antenna unit <NUM>, or the currents flowing out of the non-millimeter-wave feeding portion <NUM> may flow to the non-millimeter-wave radiating portion <NUM> formed through reusing the non-millimeter-wave antenna unit <NUM>. That is, the non-millimeter-wave feeding portion <NUM> may be connected to two non-millimeter-wave radiating portions <NUM>, and at least a part of one of the non-millimeter-wave radiating portions <NUM> is formed by reusing at least one millimeter-wave antenna unit <NUM>. Therefore, the non-millimeter-wave antenna <NUM> covering multiple frequency bands may be formed, that is, the non-millimeter-wave antenna <NUM> may transmit and/or receive wireless signals of different frequency bands with different non-millimeter-wave radiating portions <NUM>.

Optionally, with further reference to <FIG>, the millimeter antenna unit <NUM> and other parts of the mesh lines may also together form the non-millimeter-wave radiating portion <NUM>.

Alternatively, as shown in <FIG>, in two or more millimeter-wave antenna arrays <NUM>, at least one millimeter-wave antenna unit <NUM> in each millimeter-wave antenna array <NUM> may be reused as part of the non-millimeter-wave antenna <NUM> to increase the number of the non-millimeter-wave antennas <NUM>.

In some other optional embodiments, as shown in <FIG>, the non-millimeter-wave radiating portion <NUM> further includes a second connection wire <NUM> connecting the non-millimeter-wave feeding portion <NUM> to the millimeter-wave antenna unit <NUM>. The line width of a second connection wire <NUM> is different from the line width of the coil body <NUM>, so that the coil body <NUM> can allow the wireless signal currents transmitted and/or received by the loop structure <NUM> to pass through and block the non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM>.

In these optional embodiments, when at least a part of the non-millimeter-wave radiating portion <NUM> and at least one millimeter-wave antenna unit <NUM> are reused as each other, there is no connection between the second connection wire <NUM> and the coil body <NUM>.

The touch layer <NUM> includes the mesh-shaped metal wiring. The loop structure <NUM> and the antenna <NUM> are both positioned in the touch layer <NUM>. In these optional embodiments, the loop structure <NUM> and the antenna <NUM> are arranged in the touch layer <NUM>, so that the loop structure <NUM> and the antenna <NUM> can reuse the mesh-shaped metal wiring without adding an additional structure layer, which can reduce the overall thickness of the display panel. In addition, when the at least one loop structure <NUM> and the antenna <NUM> are connected to each other, the cutting points of the mesh-shaped metal wiring can be reduced to ensure desired touch effects of the touch layer <NUM> and the optical effects of the display panel.

Optionally, when the antenna <NUM> is positioned in the touch layer <NUM>, as shown in <FIG>, the millimeter-wave antenna unit <NUM> of the millimeter-wave antenna array <NUM> includes multiple first wires <NUM> extending along the first direction X and multiple second wires <NUM> extending along the second direction Y The first direction X intersects the second direction Y.

In addition, the millimeter-wave antenna unit <NUM> may directly use metal wires in the mesh-shaped metal wiring as the first wires <NUM> and the second wires <NUM>, which can further simplify the manufacturing of the millimeter-wave antenna unit <NUM>.

That is, the outer coil 101b is arranged closer to the edges of the wireless communication structure. When the coil <NUM> includes the inner coil 101a and the outer coil 101b, the antenna <NUM> may be connected to the inner coil 101a and/or the outer coil 101b. For example, as shown in <FIG>, the antenna <NUM> is connected to the outer coil 101b, when the wireless communication structure is arranged in the display panel, the antenna <NUM> is arranged closer to the edges of the display panel, which can reduce the influence of the antenna <NUM> on the display effect of the display panel. In addition, when the antenna <NUM> is arranged in the touch layer <NUM>, since the edges of the display panel are less frequently touched by the user for control, the antenna <NUM> is arranged close to the edges of the display panel, which can reduce the influence of the antenna <NUM> on the touch effect of the display panel.

When the number of antennas <NUM> is two, some of the antennas <NUM> may be connected to the inner coil 101a, and the other antennas <NUM> may be connected to the outer coil 101b. Alternatively, part of an antenna <NUM> is connected to the inner coil 101a, and the other part of the same antenna <NUM> is connected to the outer coil 101b.

The first conductive portion <NUM>, the second conductive portion <NUM> and the outer coil 101b may be arranged on a same layer. The bridge segment <NUM> and the outer coil 101b may be arranged on the different layers, so as to ensure that the millimeter-wave feeding portion <NUM> and the outer coil 101b are insulated from each other.

In some other embodiments, the outer coil 101b and the entire millimeter-wave feeding portions <NUM> may be arranged on the different layers. Optionally, when the loop structure <NUM> and the antenna <NUM> are arranged in the touch layer <NUM>, the touch layer <NUM> includes first touch electrodes and second touch electrodes arranged on a same layer. When connection portions between adjacent first touch electrodes are arranged on the same layer, adjacent second touch electrodes need to be connected to one another by bridges. The bridges and the second touch electrodes are arranged on the different layers. Optionally, the bridge segment <NUM> and the bridge of the touch layer <NUM> may be arranged on a same layer to further reduce the number of layers of the display panel, thus making the display panel lighter and thinner.

Optionally, with further reference to <FIG> and <FIG>, the inner coil 101a and the outer coil 101b are spaced apart from each other and connected in parallel with each other. The inner coil 101a and the outer coil 101b are arranged independently of each other. Both the inner coil 101a and the outer coil 101b are connected between the first connection end <NUM> and the second connection end <NUM>. Alternatively, as shown in <FIG>, the inner coil 101a and the outer coil 101b may be an inner coil part and an outer coil part of a helical coil, respectively, that is, the inner coil 101a and the outer coil 101b are connected in series with each other. When the inner coil 101a and the outer coil 101b are arranged as a helical coil, at least one of the first connection end <NUM> and the second connection end <NUM> overlaps part of the coil, and at least one of the first connection end <NUM> and the second connection end <NUM> may be arranged on a layer different from the coil body <NUM>.

As shown in <FIG>, an embodiment of the present application takes that the first connection end <NUM> and part of the coil body <NUM> overlap and are arranged on different layers as an example for illustration. When the coil body <NUM> is configured as multiple turns, the first connection end <NUM> may overlap the multi-turn coil body <NUM> in the extending path of the first connection end <NUM>. As shown in <FIG>, the first connection end <NUM> overlaps the coil body <NUM>. Optionally, as shown in <FIG>, the first connection end <NUM> includes a first segment <NUM>, a second segment <NUM> and a spanning segment <NUM> connecting the first segment <NUM> and the second segment <NUM>. The first segment <NUM> and the second segment <NUM> are positioned on both sides of the coil body <NUM>, respectively. The spanning segment <NUM> and the coil body <NUM> are arranged on the different layers. An insulation layer is arranged between the spanning segment <NUM> and the coil body <NUM>. Optionally, when the loop structure <NUM> is arranged in the touch layer <NUM>, the spanning segment <NUM> and the bridges connecting the touch electrodes may be arranged on a same layer.

Optionally, as shown in <FIG>, the multiple coils include a first coil 101e and a second coil 101f. The first coil 101e and the second coil 101f are both connected between the first connection end <NUM> and the second connection end <NUM>. Part of the first circle 101e is positioned on a side of the second coil 101f away from the center of the wireless communication structure, and part of the second coil 101f is positioned on a side of the first coil 101e away from the center of the wireless communication structure. The antenna <NUM> may be connected to the first coil 101e and/or the second coil 101f.

As shown in <FIG>, a top portion of the first coil 101e is positioned inside a top portion of the second coil 101f, and a side portion of the first coil 101e is positioned outside a side portion of the second coil 101f. Lengths of the first coil 101e and the second coil 101f can be made similar or the same, so that currents in a same frequency band can flow on the first coil 101e and the second coil 101f.

In some optional embodiments, as shown in <FIG>, the coil body <NUM> includes multiple coils. The multiple coils include a coupled coil 101c and a direct-fed coil 101d. The direct-fed coil 101d is connected between the first connection end <NUM> and the second connection end <NUM>. The coupled coil 101c is connected to the direct-fed coil 101d through coupling, which means that there is no direct connection between the coupled coil 101c and other parts of the coil body <NUM> and the coupled coil 101c is configured to generate signals by coupling with the direct-fed coil 101d.

When the coil body <NUM> includes the coupled coil 101c and the direct-fed coil 101d, the antenna <NUM> may be connected to the coupled coil 101c and/or the direct-fed coil 101d. For example, as shown in <FIG>, the coupled coil 101c is positioned on a side of the direct-fed coil 101d away from the center of the wireless communication structure, and the antenna <NUM> is connected to the coupled coil 101c. In these optional embodiments, when the wireless communication structure is arranged in the display panel, the coupled coil 101c is positioned on a side of the direct-fed coil 101d close to the edges of the display panel, and the antenna <NUM> is connected to the coupled coil 101c, so that the antenna <NUM> is arranged closer to the edges of the display panel. For example, when the antenna <NUM> is arranged in the touch layer <NUM>, the influence of the antenna <NUM> on the touch effect of the touch layer <NUM> can be reduced. In addition, the antenna <NUM> is arranged close to the edges of the display panel instead of close to the center of the display panel, which can also reduce the influence of the antenna <NUM> on the display effect of the display panel.

In other optional embodiments, as shown in <FIG>, the direct-fed coil 101d is positioned on a side of the coupled coil 101c away from the center of the wireless communication structure, and the antenna <NUM> is connected to the direct-fed coil 101d. When the wireless communication structure is arranged in the display panel, the antenna <NUM> is arranged closer to the edges of the display panel. In addition, in an embodiment of the present application, by providing the coupled coil 101c, the performance of transmitting and/or receiving the wireless signals of the loop structure <NUM> can be further improved. For example, when the loop structure <NUM> is the NFC coil, the coupled coil 101c can enhance the performance of transmitting and/or receiving the wireless signals of the NFC coil.

In some optional embodiments, as shown in <FIG>, the display panel includes a first area M and a second area N surrounding the first area M. The loop structure <NUM> is positioned in the second area N. The second area N surrounds the first area M, so that the second area N is arranged closer to the edges of the display panel. The loop structure <NUM> and the antenna <NUM> are both positioned in the second area N, which can reduce the influence of the loop structure <NUM> and the antenna <NUM> on the display effect of the display panel. When the loop structure <NUM> and the antenna <NUM> are arranged in the touch layer <NUM>, the influence of the loop structure <NUM> and the antenna <NUM> on the touch effect can also be reduced. Optionally, the antenna <NUM> may be positioned in the second area N, or the antenna <NUM> may be partially arranged in the first area M.

The second area N may be configured in various manners. For example, the second area N may include a display area; and/or the second area N is a non-display area. When the second area N includes a non-display area, the loop structure <NUM> and the antenna <NUM> are positioned in the non-display area, which can desirably reduce the influence of the loop structure <NUM> on the display effect and the touch effect. The loop structure <NUM> may be arranged in the first area M in various manners. For example, as shown in <FIG>, the loop structure <NUM> is arranged in the second area N and around the first area M, which can increase an extension length of the loop structure <NUM> and increase the extension length of the coil body <NUM> of the loop structure <NUM>, so as to implement a designed target frequency band and enhance the wireless performance of the frequency band.

Optionally, as shown in <FIG>, the first connecting end <NUM> and the second connecting end <NUM> are arranged close to each other. The coil body <NUM> extends around the first area M from the first connecting end <NUM> and then is connected to the second connecting end <NUM>. The distance between the first connecting end <NUM> and the second connecting end <NUM> is small, which not only facilitates the integration of a connector for transmitting signals from/to the first connecting end <NUM> and a connector for transmitting signals from/to the second connecting end <NUM>, but also increases the extension length of the coil body <NUM> to implement the designed target frequency band, thereby enhancing the wireless performance of the frequency band.

In some embodiments, as shown in <FIG>, the coil body <NUM> extends along a winding path. A same coil body <NUM> includes a first extension segment 130a and a second extension segment 130b that overlap each other in a direction approaching the edges of the wireless communication structure. The direction approaching the edges of the wireless communication structure may be the direction from the center of the display panel to the edge of the display panel. In these optional embodiments, the coil body <NUM> extends along the winding path, and one part overlaps another part of the coil body <NUM> in the direction approaching the edges of the wireless communication structure, which can increase the extension length of the coil body <NUM> to implement the designed target frequency band, and improve the wireless performance of the coil body <NUM>.

Optionally, the antenna <NUM> is connected to the second extension segment 130b. When the wireless communication structure is arranged in the display panel, the second extension segment 130b is closer to the edges of the display panel than the first extension segment 130a. When the antenna <NUM> is connected to the second extension segment 130b, the antenna <NUM> is closer to the edges of the display panel, which can reduce the influence of the antenna <NUM> on the touch effect and display effect of the display panel.

Optionally, as shown in <FIG>, when the coil body <NUM> includes the inner coil 101a and the outer coil 101b, the first extension segment 130a and the second extension segment 130b may be arranged on the inner coil 101a, which can also increase the extension length of the coil body <NUM>, so as to implement the designed target frequency band and improve the wireless performance of the coil body <NUM>. Optionally, as shown in <FIG>, when the coil body <NUM> includes the inner coil 101a and the outer coil 101b, the first extension segment 130a and the second extension segment 130b may be arranged on the inner coil 101a, which can also increase the extension length of the coil body <NUM>, so as to implement the designed target frequency band and improve the wireless performance of the coil body <NUM>.

In some optional embodiments, as shown in <FIG>, at least a part of the coil body <NUM> includes a first segment 130c and a second segment 130d connected to each other, that is, at least a part of the coil body <NUM> is provided with a double-stranded wire, which can reduce the impedance of the coil body <NUM> and thus reduce energy loss and energy reflection caused by impedance mismatch, thereby improving the wireless performance of the coil body <NUM>.

Optionally, the antenna <NUM> is not aligned with the first segment 130c or the second segment 130d, that is, the antenna <NUM> is connected to the non-double-stranded wire portion of the coil body <NUM>, which can simplify the connection between the antenna <NUM> and the coil body <NUM>.

In any one of the embodiments above, the millimeter-wave antenna unit <NUM> of the millimeter-wave antenna array <NUM> may be a unit of single-polarization millimeter-wave antenna array <NUM>. Alternatively, as shown in <FIG>, the millimeter-wave antenna unit <NUM> of the millimeter-wave antenna array <NUM> is a dual-polarization millimeter-wave antenna unit <NUM>.

In any of the above embodiments, different parts of the coil body <NUM> may be arranged on a same layer, that is, the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> may be arranged on a same layer. Alternatively, different parts of the coil body <NUM> may be positioned on the different layers. For example, at least two of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> are positioned on different film layers. Different parts of at least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> may be positioned on a same layer. Alternatively, different parts of at least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> may be positioned on different layers. For example, different parts of the first connection segment <NUM> may be positioned on different layers, different parts of the second connection segment <NUM> may be positioned on different layers, and/or different parts of the third connection segment <NUM> may be positioned on different layers.

For example, the first circuit board <NUM> and the second circuit board <NUM> may be provided separately from each other. In some optional embodiments, as shown in <FIG>, the first circuit board <NUM> and the second circuit board <NUM> are integrally provided, which can simplify the structure of the display apparatus.

Optionally, the wireless communication device may further include a first integrated circuit in communication with the first connecting end <NUM> and/or the second connecting end <NUM> through the first transmission line. The first integrated circuit may be arranged in various positions. The first integrated circuit may be arranged on the first circuit board <NUM>, or the first integrated circuit may be directly arranged on a printed circuit board (PCB) of the wireless communication device.

Optionally, the wireless communication device may further include a second integrated circuit <NUM> in communication with the millimeter-wave antenna array <NUM> through the second transmission line.

In an embodiment of the present application, the first integrated circuit being arranged on the PCB of the wireless communication device and the second integrated circuit <NUM> being arranged on the second circuit board <NUM> is taken as an example for illustration.

When the loop structure <NUM> is an NFC coil, the first integrated circuit is an NFC radio frequency integrated circuit. When the second integrated circuit <NUM> is in communication with the millimeter-wave antenna array <NUM>, the second integrated circuit <NUM> is a millimeter-wave radio frequency integrated circuit. Due to the filtering and frequency selecting feature of the millimeter-wave radio frequency circuit, the NFC current and the current in other non-millimeter-wave bands are significantly blocked by the millimeter-wave radio frequency circuit, and NFC current and signals in other non-millimeter-wave band do not have significant influence on the millimeter-wave radio frequency circuit, so that a desired performance of the millimeter-wave radio frequency circuit can be ensured.

Optionally, when the number of millimeter-wave antenna arrays <NUM> is two or more, the number of the second circuit boards <NUM> and the number of the second integrated circuits <NUM> are two or more.

Two or more second circuit boards <NUM> may be provided separately from each other, and a first circuit board <NUM> may be provided integrally with any of second circuit boards <NUM>. Alternatively, two or more second circuit boards <NUM> may be integrally provided, that is, a first circuit board <NUM> may be provided integrally with two or more second circuit boards <NUM>, which can further simplify the structure of the wireless communication device.

In some optional embodiments, the wireless communication device further includes a first connection socket <NUM> and a second connection socket <NUM>. The first connection socket <NUM> is provided on the first circuit board <NUM> and is in communication with the first transmission line on the first circuit board <NUM>, and is configured to enable the communication between the first integrated circuit and the coil body <NUM> through the first connection socket <NUM>. The second connection socket <NUM> is provided on the second circuit board <NUM> and is in communication with the second integrated circuit <NUM> on the second circuit board <NUM>, and is configured to enable the signal transmission between the second integrated circuit <NUM> and the PCB of the wireless communication device.

That is, when the first integrated circuit is provided on the PCB of the wireless communication device, and the second integrated circuit <NUM> is provided on the second circuit board <NUM>, the first connection socket <NUM> is configured to enable the communication between the coil body <NUM> and the first integrated circuit, and the second connection socket <NUM> is configured to enable the communication between the second integrated circuit <NUM> and the PCB of the wireless communication device.

The first connection socket <NUM> and the second connection socket <NUM> may be arranged in various manners. For example, when the first circuit board <NUM> and the second circuit board <NUM> are provided separately from each other, the first connection socket <NUM> and the second connection socket <NUM> are provided separately from each other.

In some optional embodiments, as shown in <FIG>, when the first circuit board <NUM> and the second circuit board <NUM> are integrally provided, the first connection socket <NUM> and the second connection socket <NUM> are integrally provided, which can further simplify the structure of the wireless communication device.

In some optional embodiments, as shown in <FIG>, the antenna <NUM> further includes the non-millimeter-wave antenna <NUM>. At least one millimeter-wave antenna unit <NUM> is reused as part of the non-millimeter-wave antenna <NUM>. The wireless communication device may further include a third circuit board <NUM>.

The third integrated circuit <NUM> is in communication with the non-millimeter-wave antenna <NUM>, so that the third integrated circuit <NUM> is a non-millimeter-wave radio frequency integrated circuit. Because both the non-millimeter-wave radio frequency integrated circuit and the NFC radio frequency integrated circuit have the filtering and frequency selecting feature, signals in other non-millimeter-wave bands do not have a significant influence on the NFC radio frequency integrated circuit, or NFC signals do not have a significant influence on the radio frequency integrated circuits corresponding to other non-millimeter-wave bands, so as to ensure a desired performance of the NFC radio frequency integrated circuit or radio frequency integrated circuits corresponding to other non-millimeter-wave bands.

Similarly, the third integrated circuit <NUM> is a non-millimeter-wave radio frequency integrated circuit, the second integrated circuit <NUM> is a millimeter-wave radio frequency integrated circuit, and the first integrated circuit is a NFC radio frequency integrated circuit. Due to the filtering and frequency selecting feature of the NFC radio frequency circuit, signals in the millimeter-wave band and the non-millimeter-wave band do not have a significant influence on the performance of the NFC radio frequency integrated circuit.
