Features, objects and advantages of the present application will be clearer from the detailed description of following reference drawings of non-limited embodiments. 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 devices in apparatuses with wireless communication functions are continually increasing, and types and numbers of modules used to achieve wireless communication in the apparatuses are also increasing. For example, in the era of 5th generation mobile communications, spectrum of wireless communication cover both the millimeter wave band and the non-millimeter wave band. Therefore, a wireless communication apparatus with <NUM> millimeter wave functions, such as a mobile phone, not only may be provided with a first type antenna that can be used for the millimeter wave band, but also may be provided with a wireless communication module that can be used for the non-millimeter wave band (such as those used for <NUM>, <NUM>, a wireless local area network (WLAN), Bluetooth (BT), a global navigation satellite system (GNSS), etc). At the same time, near field communication (NFC) is also becoming increasingly popular, and therefore, more and more mobile phones have NFC coils provided therein.

However, the higher the screen-to-body ratio of the display device in the wireless communication apparatus is, the more likely it is to limit the positions where the wireless communication modules can be positioned, and the wireless communication modules tend to be more likely to be obscured in use (for example, the apparatus is being held by hand or placed on a metal table), which results in that the performance of wireless communication module deteriorates significantly, and which affects the users' wireless experience. In view of the above, it is contemplated that the wireless communication modules are integrated in the display device of the wireless communication apparatus, for example, in a design of Antenna-on-Display (AoD), which has become a possible direction of development for wireless communication modules in wireless communication apparatuses.

In some embodiments, with reference to <FIG>, a wireless communication apparatus <NUM> being a cell phone is taken as an example. The wireless communication modules integrated in a display device <NUM> of the cell phone may include a <NUM> millimeter-wave antenna <NUM>, a WiFi/BT antenna <NUM>, a LTE (long term evolution) antenna <NUM>, an NFC coil <NUM> and a <NUM> non-millimeter-wave antenna <NUM>. Generally, the <NUM> millimeter-wave antenna <NUM>, the WiFi/BT antenna <NUM>, the LTE antenna <NUM>, the NFC coil <NUM> and the <NUM> non-millimeter-wave antenna <NUM> are independently arranged in the display device <NUM>. However, an internal space of the display device <NUM> is limited. How to dispose the wireless communication modules in the limited space while ensuring desired optical and touch-control effects of the display panel have become an urgent technical problem to be solved.

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

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

As illustrated in <FIG>, the display panel provided by an embodiment of the present application includes a wireless communication structure. There are various ways of arranging the wireless communication structure. As illustrated in <FIG>, the wireless communication structure provided by an embodiment 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> includes a millimeter-wave antenna unit <NUM> configured to transmit and/or receive wireless signals in millimeter-wave band. The millimeter-wave antenna unit <NUM> is connected to the coil body <NUM> of at least one loop structure <NUM>.

The millimeter-wave antenna unit <NUM> configured to transmit and/or receive wireless signals in millimeter-wave band refers to the millimeter-wave antenna unit <NUM> configured to transmit and/or receive wireless signals in millimeter-wave band, that is, the "transmit and/or receive" herein refers to transmit and/or receive. The millimeter-wave antenna unit <NUM> includes a millimeter-wave feeding portion and a millimeter radiating portion. Optionally, the millimeter-wave feeding portion and/or the millimeter radiating portion are connected to the coil body <NUM> of at least one loop structure <NUM>.

In the wireless communication structure provided by an embodiment of the present application, the wireless communication structure includes at least one loop structure <NUM> and the antenna <NUM>. The loop structure <NUM> is configured to transmit and/or receive signals on the coil body <NUM> through the first connection end <NUM> and the second connection end <NUM>. The antenna <NUM> includes the millimeter-wave antenna unit <NUM> configured to transmit and/or receive wireless signals in millimeter-wave band. The millimeter-wave antenna unit <NUM> is connected to the coil body <NUM> of at least one loop structure <NUM>, which can not only reduce an overall area occupied by the loop structure <NUM> and the antenna <NUM>, so that a plurality of wireless communication modules can be arranged in a limited space. In addition, at least one loop structure <NUM> and the millimeter-wave antenna unit <NUM> of the antenna <NUM> are connected to each other, which can ensure a desired optical performance of the display screen and simplify patterning process of the antenna, thereby improving the manufacturing efficiency and reducing the manufacturing cost of the wireless communication module.

As an optional embodiment, with further reference to <FIG>, when the wireless communication structure is used for the display panel, the display panel further includes a touch-control layer <NUM> including a metal wiring in a grid pattern, which are illustrated as light-colored grid lines in <FIG>. When the loop structure <NUM> and the antenna <NUM> are arranged in the touch-control layer <NUM>, a part of the metal wiring for connecting at least one loop structure <NUM> and the millimeter-wave antenna unit <NUM> do not need to be cut in a connection direction, so the number of cutting points of the metal wiring in a grid pattern can be reduced. The issues of increased touch-control blind spots, deterioration of touch-control performance and degraded experience caused by the wireless communication structure being arranged in the touch layer <NUM> can be improved, so as to ensure a desired touch-control performance of the display screen. In addition, a connection part between at least one loop structure <NUM> and the millimeter-wave antenna unit <NUM> does not need to be cut in the connection direction, so that patterns of the metal wiring in a grid pattern in different areas tend to be uniform, and thus an optical effect of the display panel can be improved.

The coil body <NUM> is a loop coil, which may be arranged 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 coils, a GNSS coil, a WLAN coil, a BT coil, and a frequency modulation (FM) coil and the like. The NFC coil, the WPC coil, the LTE coil, the GNSS coil, the WLAN coil, the BT coil, the FM coil and the like can each be arranged as a loop coil, so as to facilitate the connection of the millimeter-wave antenna unit <NUM> therewith.

Optionally, the loop structure <NUM> includes at least one of the NFC coil and the WPC coil. The loop structure <NUM> including the NFC coil and/or the WPC coil is typically large in size. For example, the loop structure <NUM> including the NFC coil and/or the WPC coil is arranged close to and around the edges of the display panel, so as to facilitate the series connection of the millimeter-wave antenna unit <NUM> in the loop structure <NUM> including the NFC coil and/or the WPC coil. In addition, the millimeter-wave antenna unit <NUM> can be arranged closer to the edges of the display panel, so that the deterioration of the optical and touch-control effects of the display panel caused by the millimeter-wave antenna unit <NUM> can be insignificant, and the feeding path of the millimeter-wave antenna unit <NUM> can be shorter. Therefore, feeding loss can be lower, so as to achieve a desired radiation performance of the millimeter-wave antenna unit <NUM>.

Reference is made to <FIG>, which is 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>, the antenna <NUM> includes a plurality of millimeter-wave antenna units <NUM>. At least two of the millimeter-wave antenna units <NUM> form a millimeter-wave antenna array <NUM>. At least one millimeter-wave antenna unit <NUM> in the millimeter-wave antenna array <NUM> is connected to the coil body <NUM>. In <FIG>, the position of the millimeter-wave antenna array <NUM> is indicated by a dashed-dotted line. The dashed-line frame does not limit the structure of the wireless communication structure of the embodiments of the present application.

As shown in <FIG>, each millimeter-wave antenna unit <NUM> in the millimeter-wave antenna array <NUM> is connected to the coil body <NUM>. The coil body <NUM> connected to the millimeter-wave antenna array <NUM> includes a first connection segment <NUM>, a second connection segment <NUM> and a third connection segment <NUM>. The first connection segment <NUM> is connected between the first connection end <NUM> and the millimeter-wave antenna array <NUM>. The second connection segment <NUM> is connected between the millimeter-wave antenna array <NUM> and the second connection end <NUM>. The third connection segment <NUM> is connected between two adjacent millimeter-wave antenna units <NUM> in a same millimeter-wave antenna array <NUM>. Through the first connection segment <NUM> and the second connection segment <NUM>, the millimeter-wave antenna array <NUM> can be connected between the first connection end <NUM> and the second connection end <NUM>. The third connection segment <NUM> is connected between two adjacent millimeter-wave antenna units <NUM> in a same millimeter-wave antenna array <NUM>, which can reduce the overall area occupied by the loop structure <NUM> and the antenna <NUM>, and can further simplify a pattern of the loop structure <NUM> and the antenna <NUM>.

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

Optionally, as shown in <FIG>, the antenna <NUM> includes a plurality of millimeter-wave antenna arrays <NUM>. The first connection segment <NUM> is connected between one of the millimeter-wave antenna arrays <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 millimeter-wave antenna arrays <NUM>, and the second sub-segment 132b is connected between another millimeter-wave antenna array <NUM> and the second connection end <NUM>. The first sub-segment 132a is configured to realize the connection between the two adjacent millimeter-wave antenna arrays <NUM>, and the second sub-segment 132b is configured to realize the connection between the millimeter-wave antenna array <NUM> and the second connection end <NUM>. As such, the second connection segment <NUM> is divided into a plurality of segments. A part of the second connection segment <NUM> (for example, the first sub-segment 132a) is for connecting the two adjacent millimeter-wave antenna arrays <NUM>, and a part of the second connection segment <NUM> (for example, the second sub-segment 132b) is for connecting the millimeter-wave antenna array <NUM> and the second connection end <NUM>.

As shown in <FIG>, the antenna <NUM> includes three millimeter-wave antenna arrays <NUM>. Two of the millimeter-wave antenna arrays <NUM> are arranged as opposite to each other along a first direction X, that is, the two millimeter-wave antenna arrays <NUM> are correspondingly arranged on the two opposite edges of the display panel along the first direction X, and the two millimeter-wave antenna arrays <NUM> are not necessarily to be directly opposite to each other. The other millimeter-wave antenna array <NUM> is arranged as opposite to the first connection end <NUM> and the second connection end <NUM> along a second direction Y, so that the first connection end <NUM>, the second connection end <NUM> and the three millimeter-wave antenna arrays <NUM> are distributed around the circumference of the display panel in a spaced manner, and the millimeter-wave antenna arrays <NUM> are distributed in different positions of the display panel. When a user uses different gestures to operate the display panel, there is always a millimeter-wave antenna array <NUM> that is in a position that is not blocked by the user, so the stability of the millimeter-wave antenna array <NUM> for transmitting and/or receiving wireless signals can be improved, and a desired user wireless experience can be ensured.

In some other optional embodiments, as shown in <FIG>, the first connection end <NUM> and the second connection end <NUM> may be arranged in a spaced manner from a millimeter-wave antenna array <NUM> along the first direction X, that is, the first connection end <NUM> and the second connection end <NUM> are arranged by the side of one of the millimeter-wave antenna arrays <NUM>.

Optionally, the shape of the millimeter-wave antenna unit <NUM> may be set in various manners. For example, the shape of the millimeter-wave antenna unit <NUM> may be a square, a diamond, or the like.

In any of the above embodiments, the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> can be arranged in various manners. For example, the first connection segment <NUM> may include one wire, or the first connection segment <NUM> may include a plurality of wires arranged side by side, or the first connection segment <NUM> may include a plurality of wires arranged side by side and a bridge wire connecting the plurality of wires arranged side by side. Similarly, the second connection segment <NUM> and/or the third connection segment <NUM> may comprise one wire, or the second connection segment <NUM> and/or the third connection segment <NUM> may include a plurality of wires arranged side by side, or the second connection segment <NUM> and/or the third connection segment <NUM> may include a plurality of wires arranged side by side and a bridge wire connecting the plurality of wires arranged side by side.

As shown in <FIG>, the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> includes one wire. Alternatively, as shown in <FIG>, the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> includes two or more wires.

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 that the corresponding currents are concentrated in 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 will increase. In addition, due to the skin effect mentioned above, an inductance faced by the high-frequency signal will also increase, which further increases the inductive reactance.

To sum up, when a frequency of a signal increases, flowing of a current corresponding to the signal on the conductor will be blocked. Therefore, under conditions of a same conductor, a current corresponding to a high-frequency signal is more liable to be blocked than a current corresponding to a low-frequency signal. In addition, when a width of the conductor is reduced, the inductance of the conductor will increase, and therefore, the inductive reactance will further increase, so that flowing of the current corresponding to the high-frequency signal will be further blocked. Therefore, by adjusting the size of the conductor, currents corresponding to signals of different frequencies 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 conditions of a same conductor, the millimeter-wave currents corresponding to the frequency band of the wireless signals in the millimeter-wave band are more likely to be blocked and less likely 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.

The line width of at least part of at least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> is less than the width of the millimeter-wave antenna unit <NUM>. Optionally, the millimeter-wave antenna unit <NUM> includes a millimeter-wave wire. The line width of at least part of at least one of the first connection segment <NUM>, the second connection segment <NUM> and the third connection segment <NUM> is not greater than the width of the millimeter-wave wire in the millimeter-wave antenna unit <NUM>.

For example, the line width of at least part of the first connection segment <NUM> is not greater than the width of the millimeter-wave antenna unit. When the millimeter-wave antenna unit <NUM> is in a block shape, the millimeter-wave antenna unit <NUM> can be understood as including one millimeter-wave wire. When the millimeter-wave antenna unit <NUM> includes a plurality of millimeter-wave wires, the line width of at least part of the first connection segment <NUM> being less than the width of the millimeter-wave antenna unit <NUM> means that the line width of at least part of the first connection segment <NUM> is less than the sum of the widths of the plurality of millimeter-wave wires in the millimeter-wave antenna unit <NUM>.

In an embodiment of the present application, when the line width of at least part of the first connection segment <NUM> is not greater than the width of the millimeter-wave wire in the millimeter-wave antenna unit <NUM>, the line width of the first connection segment <NUM> is small, so the first connection segment <NUM> has a high impedance. As described above, the wireless signals in millimeter-wave band transmitted and/or received by the millimeter-wave antenna unit <NUM> are in a high frequency band, so that the millimeter-wave currents corresponding to the frequency band of the wireless signals in millimeter-wave band transmitted and/or received by the millimeter-wave antenna unit <NUM> cannot pass through the first connection segment <NUM>. Therefore, the first connection segment <NUM> has a desired filtering and blocking effect on the millimeter-wave currents. However, the first connection segment <NUM> can have a desired passing effect on non-millimeter-wave current corresponding to the non-millimeter-wave frequency bands in the era of the 5th generation mobile communications (<NUM>) and its previous generations mobile communications, WLAN or Bluetooth, and the first connection segment <NUM> can also have a desired passing effect on non-millimeter-wave current corresponding to the NFC frequency band. Therefore, in an embodiment of the present application, the current of the loop structure <NUM> can desirably pass through the first connection segment <NUM>, while the millimeter-wave currents are significantly blocked by the first connection segment <NUM>.

The millimeter-wave currents refer to the currents corresponding to the frequency band of the wireless signals in millimeter-wave band transmitted and/or received by the millimeter-wave antenna unit <NUM>. The wireless signal currents refer to the currents corresponding to the frequency band of the wireless signals transmitted and/or received by the loop structure <NUM>.

The configuration of the line width of at least part of the second connection segment <NUM> and/or the third connection segment <NUM> being not greater than the width of the millimeter-wave antenna unit <NUM> and its beneficial effects are the same as above, and will not be repeated here.

Optionally, the line widths of the first connection segment <NUM>, the second connection segment <NUM>, and the third connection segment <NUM> are each set to be not greater than the line width of the millimeter-wave wire. The 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 as to desirably ensure the independence of each millimeter-wave antenna unit <NUM> in the millimeter-wave antenna array <NUM>, and ensure a desired performance of the millimeter-wave antenna array <NUM>.

Optionally, when the line width of at least part of the third connection segment <NUM> is not greater than the width of the millimeter-wave antenna unit <NUM>, as shown in <FIG>, when the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> includes one wire, the line width of one wire 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> in the same extension direction as the third connection segment <NUM>. As shown in <FIG>, when the third connection segment <NUM> between two adjacent millimeter-wave antenna units <NUM> includes a plurality of wires, the sum of the line widths of the plurality of 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> in the same extension direction as the third connection segment <NUM>. As shown in <FIG>, when the first direction X is perpendicular to the second direction Y, and the third connection segment <NUM> extends along the second direction Y, a line width direction of the third connection segment <NUM> is the first direction X, and the width direction of the millimeter-wave wire is also the first direction X. In some other embodiments, when the third connection segment <NUM> extends along the first direction X, the line width direction of the third connection segment <NUM> is the second direction Y.

In an embodiment of the present application, when the sum of the line widths of the 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> in the same extension direction as the third connection segment <NUM>, that is, the width of the third connection segment <NUM> is small, the third connection segment <NUM> has a high impedance. Therefore, the third connection segment <NUM> has a desired filtering and blocking effect on the currents in the millimeter-wave band. However, the third connection segment <NUM> can have a desired passing effect on non-millimeter-wave current corresponding to the non-millimeter-wave frequency bands in the era of the 5th generation mobile communications (<NUM>) and its previous generations mobile communications, WLAN, BT or GNSS, and the third connection segment <NUM> can also have a desired passing effect on non-millimeter-wave currents corresponding to the NFC frequency band. Therefore, in an embodiment of the present application, the current of the loop structure <NUM> can desirably pass through the third connection segment <NUM>, while the millimeter-wave currents are significantly blocked by the third connection segment <NUM>. However, the millimeter-wave currents can desirably flow in the millimeter-wave antenna unit <NUM>, which can desirably ensure the independence of each millimeter-wave antenna unit <NUM> in the millimeter-wave antenna array <NUM> and ensure a desired performance of the millimeter-wave antenna array <NUM>.

Optionally, the sum of the line widths of the wires in the second 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> in the same extension direction as the second connection segment <NUM>. As shown in <FIG>, when the second connection segment <NUM> extends along the first direction X, the line width direction of the second connection segment <NUM> is the second direction Y, and when the second connection segment <NUM> extends along the second direction Y, the line width direction of the second connection segment <NUM> is the first direction X.

As mentioned above, the line width of the second connection segment <NUM> is small, which can desirably block the millimeter-wave currents, and desirably allow the currents corresponding to the non-millimeter-wave band and the NFC frequency band to pass through. As such, the second connection segment <NUM> can desirably block the currents corresponding to the millimeter-wave band and ensure a desired performance of the millimeter-wave antenna array <NUM> and a desired performance of the millimeter-wave antenna unit <NUM>, without much affecting the currents corresponding to other non-millimeter-wave band and the NFC frequency band.

Optionally, the sum of the line widths of the wires in 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 unit <NUM> in the same extension direction as the first connection segment <NUM>. As shown in <FIG>, when the first connection segment <NUM> extends along the first direction X, the line width direction of the first connection segment <NUM> is the second direction Y, and when the first connection segment <NUM> extends along the second direction Y, the line width direction of the first connection segment <NUM> is the first direction X.

As mentioned above, the line width of the first connection segment <NUM> is small, which can desirably block the millimeter-wave currents, and desirably allow the currents corresponding to the non-millimeter-wave band and the NFC frequency band to pass through. As such, the first connection segment <NUM> can desirably block the currents corresponding to the millimeter-wave band and ensure a desired performance of the millimeter-wave antenna array <NUM> and a desired performance of the millimeter-wave antenna unit <NUM>, without much affecting the currents corresponding to other non-millimeter-wave band and the NFC frequency band.

In addition, in an embodiment of the present application, the antenna <NUM> includes a plurality of millimeter-wave antenna units <NUM>. The plurality of 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 a large radiation path loss, and can achieve an effect of beam scanning to cover a wide space so as to reduce wireless communication blind spots and achieve a desired user wireless experience.

There are various manners of setting the shape of the third connection segment <NUM>. The third connection segment <NUM> may be in the shape of a straight line, that is, the third connection segment <NUM> extends in a same direction. Alternatively, the third connection segment <NUM> may be in the shape of a polyline, 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> is formed by a combination of at least two of a straight line, a polyline, and an arc.

Optionally, when the millimeter-wave antenna array <NUM> includes a plurality of millimeter-wave antenna units <NUM>, in the direction from the first connection end <NUM> to the second connection end <NUM>, the first connection segment <NUM> is connected to a first antenna unit among the plurality of millimeter-wave antenna units <NUM>, or the second connection segment <NUM> is connected to a last antenna unit among the plurality of millimeter-wave antenna units <NUM>.

For example, as shown in <FIG>, the millimeter-wave antenna array <NUM> includes four millimeter-wave antenna units <NUM>. The four millimeter-wave antenna units <NUM> are respectively the first antenna unit, a second antenna unit, a third antenna unit and a fourth antenna unit along their arrangement direction (the second direction Y). On an extension path from the first connection end <NUM> to the second connection end <NUM>, the first antenna unit is positioned on a side, in the four millimeter-wave antenna units <NUM>, close to the first connection end <NUM>, and the fourth antenna unit is positioned on a side, in the four millimeter-wave antenna units <NUM>, close to the second connection end <NUM>. As such, and the first connection segment <NUM> is connected between the first antenna unit and the first connection end <NUM>. The fourth antenna unit is the last antenna unit, and the second connection segment <NUM> is connected between the fourth antenna unit and the second connection end <NUM>.

Optionally, the third connection segment <NUM> is connected between the first antenna unit and the second antenna unit, the third connection segment <NUM> is connected between the second antenna unit and the third antenna unit, and the third connection segment <NUM> is connected between the third antenna unit and the fourth antenna unit.

In some optional embodiments as shown in <FIG>, the antenna <NUM> further includes a non-millimeter-wave antenna <NUM> for transmitting and/or receiving wireless signals in non-millimeter-wave band. The non-millimeter-wave antenna <NUM> is connected to the coil body <NUM>. In an embodiment of the present application, the millimeter-wave antenna unit <NUM> and the non-millimeter-wave antenna <NUM> are connected to the coil body <NUM>, which can further improve a light-emitting effect of the display panel. When the antenna <NUM> and the loop structure <NUM> are arranged in the touch-control layer <NUM>, the number of cutting points can be further reduced and a touch effect can be improved.

Optionally, at least one millimeter-wave antenna unit <NUM> is reused as a part of the non-millimeter-wave antenna <NUM>.

The at least one millimeter-wave antenna unit <NUM> being reused as a part of the non-millimeter-wave antenna <NUM> may be implemented in a manner in which one millimeter-wave antenna unit <NUM> is reused as a part of the non-millimeter-wave antenna <NUM>, or at least two adjacent millimeter-wave antenna units <NUM> are connected through the third connection segment <NUM> and reused as a part of the non-millimeter-wave antenna <NUM>. At least two adjacent millimeter-wave antenna units <NUM> being connected through the third connection segment <NUM> and reused as a part of the non-millimeter-wave antenna <NUM> means that the at least two adjacent millimeter-wave antenna units <NUM>, when connected through the third connection segment <NUM>, can have the function of the non-millimeter-wave antenna <NUM> and be configured for transmitting and/or receiving wireless signals in non-millimeter-wave band.

Optionally, the non-millimeter-wave antenna <NUM> includes a first portion <NUM> and a second portion <NUM>. The first portion <NUM> is a radiating portion. The second portion <NUM> is a feeding portion. One millimeter-wave antenna unit <NUM> may be reused as a part of the first portion <NUM>. For example, one millimeter-wave antenna unit <NUM> and a part of the coil body <NUM> are connected to each other and reused as a part of the first portion <NUM>. Alternatively, two or more millimeter-wave antenna units <NUM> may be connected to one another and reused as the first portion <NUM>, and the first portion <NUM> is connected to the second portion <NUM>.

When at least one millimeter-wave antenna unit <NUM> is reused as at least a part of the non-millimeter-wave antenna <NUM>, the at least one millimeter-wave antenna unit <NUM> may be connected to the feeding portion of the non-millimeter-wave antenna <NUM>, that is, the at least one millimeter-wave antenna unit <NUM> may be connected to the second portion <NUM> of the non-millimeter-wave antenna <NUM>. For example, the at least one millimeter-wave antenna unit <NUM> may be connected to the second portion <NUM> of the non-millimeter-wave antenna <NUM> through a part of the coil body <NUM>, so that the at least one millimeter-wave antenna unit <NUM> can be connected to a radio frequency integrated circuit of the non-millimeter-wave antenna <NUM>, so as to realize the function of the non-millimeter-wave antenna <NUM>.

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

In these optional embodiments, the reusing of the non-millimeter-wave antenna <NUM>, the millimeter-wave antenna unit <NUM> and at least a part of the loop structure <NUM> can further simplify the area occupied by the various antennas and simplify the layout patterns of the various antennas. Therefore, the number of cutting spots in metal wiring in a grid pattern can be reduced, and a desired display performance and touch-control performance of the display panel can be ensured.

Optionally, as shown in <FIG>, the coil body <NUM> includes a blocking portion <NUM>, and the blocking portion <NUM> is configured to allow wireless signal currents transmitted and/or received by the loop structure <NUM> to pass through and significantly block non-millimeter-wave currents transmitted and/or received by the non-millimeter-wave antenna <NUM> and millimeter-wave currents transmitted and/or received by the millimeter-wave antenna unit <NUM>. Therefore, by providing the blocking portion <NUM>, the non-millimeter-wave currents can be blocked, and the performance of the non-millimeter-wave antenna <NUM> can be designed and ensured in a better controllable manner.

For example, when the loop structure <NUM> is an NFC coil, the blocking portion <NUM> is configured to allow wireless signal currents corresponding to the NFC frequency band to pass through. When the loop structure <NUM> is a WPC, the blocking portion <NUM> is configured to allow wireless signal currents corresponding to the WPC frequency band to pass through.

There are various manners of arranging the blocking portion <NUM>. For example, the blocking portion <NUM> can be arranged by changing the width of at least a part of the coil body <NUM>, that is, the blocking portion <NUM> can be arranged by changing the thickness of the coil body <NUM>, so as to block the currents corresponding to the non-millimeter-wave band. The user can set the positions, the widths, the lengths, the shapes, the film layer positions and the number of the blocking portions <NUM> according to the frequency band of the wireless signals in non-millimeter-wave band transmitted and/or received by the non-millimeter-wave antenna <NUM> and the frequency band of the wireless signals transmitted and/or received by the loop structure <NUM> in actual use, so as to block non-millimeter-wave currents and achieve the design of a target operating frequency in the non-millimeter-wave band.

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

In some optional embodiments, as shown in <FIG>, the width of the blocking portion <NUM> may not be greater than the width of the other portion of the coil body <NUM>.

There are various positions for disposing the blocking portion <NUM>. The 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>. For example, when the blocking portion <NUM> is arranged on the first sub-segment 132a shown in <FIG>, the millimeter-wave antenna units <NUM> of the millimeter-wave antenna array <NUM> between the first sub-segment 132a and the first connection end <NUM> are reused as the non-millimeter-wave antenna <NUM>. The feeding portion (i.e., the second portion <NUM>) of the non-millimeter-wave antenna <NUM> is arranged between the first sub-segment 132a and the first connection end <NUM>. As such, the current of the non-millimeter-wave antenna <NUM> can flow toward the blocking portion <NUM>, or the current of the non-millimeter-wave antenna <NUM> can flow toward the first connection end <NUM>, thereby forming a dual-frequency band non-millimeter-wave antenna <NUM>.

In some other optional embodiments, the coil body <NUM> includes two or more blocking portions <NUM>. For example, as shown in <FIG>, the coil body <NUM> includes two blocking portions <NUM>. One of the blocking portions <NUM> is positioned on the first sub-segment 132a, and the other blocking portion <NUM> is positioned on the first connection segment <NUM> between the second portion <NUM> and the first connection end <NUM>. As such, the current of the non-millimeter-wave antenna <NUM> can flow toward the blocking portion <NUM> positioned on the first sub-segment 132a, or the current of the non-millimeter-wave antenna <NUM> can flow toward the blocking portion <NUM> positioned on the first connection segment <NUM>, thereby forming a dual-frequency band non-millimeter-wave antenna <NUM>. In addition, by appropriately setting the position of the blocking portion <NUM>, the frequency band of the non-millimeter-wave antenna <NUM> can be controlled, so as to achieve the purpose of more accurately controlling the frequency band of the wireless signals transmitted and/or received by the non-millimeter-wave antenna <NUM>.

In still some optional embodiments, the 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> of the millimeter-wave antenna array <NUM> in <FIG> are reused as the non-millimeter-wave antenna <NUM>, and the blocking portion <NUM> can be provided between the plurality of antenna units <NUM> reused as the non-millimeter-wave antenna array <NUM> and the other millimeter-wave antenna units <NUM>.

Optionally, in <FIG>, for example, the blocking portions <NUM> are the first blocking portion 140a, the second blocking portion 140b and the third blocking portion 140c, respectively. The current flowing out from the second portion <NUM> of the non-millimeter-wave antenna <NUM> can flow to the first blocking portion 140a, or the current flowing out from the second portion <NUM> of the non-millimeter-wave antenna <NUM> can flow to the second blocking portion 140b.

Optionally, in <FIG>, the non-millimeter-wave antenna <NUM> is a non-millimeter-wave antenna <NUM> covering a plurality of target frequency bands, that is, the currents flowing from the second portion <NUM> to the first blocking portion 140a and the second blocking portion 140b are each a current in the frequency bands of 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 target frequency band. For example, when the current flowing out from the second portion <NUM> of the non-millimeter-wave antenna <NUM> flows to the second blocking portion 140b, the current is a current in the target frequency band of the non-millimeter-wave antenna <NUM>. An appropriate design of a wire path from the second portion <NUM> to the first blocking portion 140a can have a beneficial effect on the performance of the target frequency band of the non-millimeter-wave antenna <NUM>.

Optionally, a plurality of millimeter-wave antenna units <NUM> in the millimeter-wave antenna array <NUM> may be reused as two non-millimeter-wave antennas <NUM>. The blocking portion <NUM> may be arranged between the plurality of millimeter-wave antenna units <NUM> reused as different non-millimeter-wave antenna arrays <NUM>. For example, the millimeter-wave antenna array <NUM> in <FIG> includes <NUM> millimeter-wave antenna units <NUM>, wherein two adjacent millimeter-wave antenna units <NUM> are reused as the non-millimeter-wave antenna <NUM>, then the blocking portion <NUM> can be arranged at a middle position of <NUM> millimeter-wave antenna units <NUM>.

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

Optionally, the line width of the blocking portion <NUM> may be less than that of the other portion of the coil body <NUM>, or the line width of the blocking portion <NUM> may be greater than that of the other portion of the coil body <NUM>.

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

There are various positions for disposing the loop structure <NUM> and the antenna <NUM>. As shown in <FIG>, in some optional embodiments, the display panel further includes a touch-control layer <NUM> including a metal wiring in a grid pattern, and the loop structure <NUM> and the antenna <NUM> are positioned in the touch-control layer <NUM>.

In these optional embodiments, the loop structure <NUM> and the antenna <NUM> are arranged in the touch-control layer <NUM>, so that the loop structure <NUM> and the antenna <NUM> can reuse the metal wiring in a grid pattern without adding a new structure layer, which can reduce the overall thickness of the display panel. In addition, when at least one loop structure <NUM> and the antenna <NUM> are connected to each other, the cutting points of the metal wiring in a grid pattern can be reduced, so as to ensure a desired touch-control effect of the touch-control layer <NUM> and the optical effect of the display panel at the same time.

Optionally, when the antenna <NUM> is positioned in the touch-control layer <NUM>, as shown in <FIG>, the millimeter-wave antenna unit <NUM> includes a plurality of first wires <NUM> extending along the first direction X and a plurality of second wires <NUM> extending along the second direction Y. The first direction X is intersected with the second direction Y. For example, the first direction X and the second direction Y are perpendicular to each other, or the angle between the first direction X and the second direction Y is <NUM> degrees, <NUM> degrees, <NUM> degrees, etc., as long as the first direction X is intersected with the second direction Y.

In these optional embodiments, the millimeter-wave antenna unit <NUM> includes intersecting first wires <NUM> and second wires <NUM>, that is, the millimeter-wave antenna unit <NUM> is in a grid pattern, which can increase an area of the millimeter-wave wires in the millimeter-wave antenna unit <NUM>, thereby reducing the impedance of the millimeter-wave antenna unit <NUM>, which can reduce the energy loss of the millimeter-wave antenna unit <NUM> and the energy reflection caused by impedance mismatch, so that the millimeter-wave antenna unit <NUM> can desirably transmit and/or receive wireless signals in the millimeter-wave band. In addition, the millimeter-wave antenna unit <NUM> can directly use the metal wires in the metal wiring in a grid pattern as the first wire <NUM> and the second wire <NUM>, which can further simplify the formation of the millimeter-wave antenna unit <NUM>.

The millimeter-wave antenna unit <NUM> includes intersecting first wires <NUM> and second wires <NUM>, that is, the millimeter-wave wires include intersecting first wires <NUM> and second wires <NUM>.

Optionally, the touch-control layer <NUM> may be formed through intersection of a plurality of first touch-control lines parallel to the first wires <NUM> and a plurality of second touch-control lines parallel to the second wires <NUM>.

In some other embodiments, as shown in <FIG>, the display panel may further include an antenna layer. The loop structure <NUM> and the antenna <NUM> are positioned in the antenna layer. In these optional embodiments, an antenna layer in a non-grid pattern is additionally provided in the display panel, so that the impedance of the antenna <NUM> and the loop structure <NUM> can be reduced, and the energy loss of the antenna <NUM> and the loop structure <NUM> and the energy reflection caused by impedance mismatch can be reduced, so as to improve the performance of the antenna <NUM> and the loop structure <NUM>. Optionally, the loop structure <NUM> and the antenna <NUM> in the antenna layer may be formed by etching. In other embodiments, the antenna layer may be independently arranged and mounted on the display panel. Other embodiments may be selected to use for the formation the loop structure <NUM> and the antenna <NUM> in the antenna layer.

When the loop structure <NUM> and the antenna <NUM> are arranged in the antenna layer, the millimeter-wave antenna unit <NUM> may be in a block shape, so as to increase the area of the conductive material in the millimeter-wave antenna unit <NUM> and reduce the impedance of the millimeter-wave antenna unit <NUM> and the energy reflection caused by impedance mismatch, so that the millimeter-wave antenna unit <NUM> can have better performance for transmitting and/or receiving wireless signals of millimeter-waves.

When the millimeter-wave antenna unit <NUM> is in a block shape, the millimeter-wave antenna unit <NUM> may be in a shape of a square, a diamond, a circle, or the like.

Optionally, when the loop structure <NUM> and the antenna <NUM> are arranged by additionally providing the antenna layer in the display panel, and the display panel has the touch-control layer <NUM>, the antenna layer may be arranged on a side of the touch-control layer <NUM> facing a cover plate of the display panel, or the antenna layer may be arranged on a side of the touch-control layer <NUM> facing away from the cover plate of the display panel.

In some optional embodiments, as shown in <FIG>, when the coil body <NUM> includes a plurality of coils, the millimeter-wave antenna unit <NUM> is connected to at least one of the plurality of coils. The plurality of coils may be connected in series, parallel or coupled with one another. The plurality of coils may be arranged to intersect or be spaced apart from one another.

When the number of the millimeter-wave antenna unit <NUM> is one, the millimeter-wave antenna unit <NUM> may be connected to one of the coils. When the antenna <NUM> includes a plurality of millimeter-wave antenna units <NUM>, different millimeter-wave antenna units <NUM> may be connected to different coils, or different millimeter-wave antenna units <NUM> may be connected to a same coil.

Optionally, the plurality of coils include an inner coil 101a and an outer coil 101b surrounding a side of the inner coil 101a away from the center of the wireless communication structure. Each of the inner coil 101a and the outer coil 101b is connected between the first connection end <NUM> and the second connection end <NUM>. That is, the outer coil 101b is arranged closer to the edges of the wireless communication structure.

When the coil body <NUM> includes the inner coil 101a and the outer coil 101b, the millimeter-wave antenna unit <NUM> may be connected to the inner coil 101a and/or the outer coil 101b.

For example, as shown in <FIG>, the millimeter-wave antenna unit <NUM> is connected to the outer coil 101b. When the wireless communication structure is used for the display panel, the millimeter-wave antenna unit <NUM> being arranged closer to the edges of the display panel can reduce the influence of the millimeter-wave antenna unit <NUM> on the display effect of the display panel. When the antenna <NUM> is arranged in the touch-control layer <NUM>, since the user touches the edges of the display panel in a less frequency, the millimeter-wave antenna unit <NUM> being arranged close to the edges of the display panel can also reduce its influence on the touch-control effect.

Alternatively, a part of the millimeter-wave antenna array <NUM> is connected with the inner coil 101a in series, and the other part of the millimeter-wave antenna array <NUM> is connected with the outer coil 101b in series.

The millimeter-wave antenna unit <NUM> is connected to the inner coil 101a. The millimeter-wave antenna unit <NUM> may be arranged in the same layer as the inner coil 101a and the outer coil 101b. At least a part of the millimeter-wave feeding portion <NUM> is arranged in a different layer from the outer coil 101b. When the millimeter-wave antenna unit <NUM> is connected to the inner coil 101a, the millimeter-wave feeding portion <NUM> and the outer coil 101b intersect, and at least a part of the millimeter-wave feeding portion <NUM> and the outer coil 101b being arranged in different layers can ensure that the millimeter-wave feeding portion <NUM> and the outer coil 101b are insulated from each other.

Optionally, the millimeter-wave feeding portion <NUM> includes a first conduction portion <NUM>, a second conduction portion <NUM>, and a bridge segment <NUM> connected between the first conduction portion <NUM> and the second conduction portion <NUM>. The first conduction portion <NUM>, the second conduction portion <NUM>, and the outer coil 101b may be arranged in a same layer, and the bridge segment <NUM> and the outer coil 101b may be arranged in 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 entire millimeter-wave feeding portion <NUM> may be arranged in a different layer from the outer coil 101b.

Optionally, when the loop structure <NUM> and the antenna <NUM> are arranged in the touch-control layer <NUM>, the touch-control layer <NUM> includes a first touch-control electrode and a second touch-control electrode arranged in a same layer. When the connection portions between the adjacent first touch-control electrodes are arranged on the same layer as the first touch-control electrode, adjacent second touch-control electrodes need to be connected to one another through bridges, and the bridges and the second touch-control electrodes are arranged in different layers. Optionally, the bridge segment <NUM> may be arranged in a same layer as the bridge of the touch-control layer <NUM>, so as to further reduce the number of layers of the display panel and make 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 with each other in parallel. The inner coil 101a and the outer coil 101b are arranged independently from each other. Each of the inner coil 101a and the outer coil 101b is connected between the first connection end <NUM> and the second connection end <NUM>.

Optionally, as shown in <FIG>, the coil bodies <NUM> are connected with one another in series and arranged in a spiral shape.

The inner coil 101a and the outer coil 101b may be an inner coil part and an outer coil part of the spiral coil, that is, the inner coil 101a and the outer coil 101b are connected with each other in series.

When the inner coil 101a and the outer coil 101b are spiral coils, at least one of the first connection end <NUM> and the second connection end <NUM> overlaps with a part of the coil, and at least one of the first connection end <NUM> and the second connection end <NUM> may be arranged in different layers from a part of the coil body <NUM>.

As shown in <FIG>, an embodiment of the present application takes that the first connection end <NUM> and a part of the coil body <NUM> overlap and are arranged in different layers as an example for illustration. When the coil body <NUM> is arranged in a plurality of turns, on the extending path of the first connection end <NUM>, the first connection end <NUM> may be set to overlap with the coil body <NUM> which is arranged in the plurality of turns. As shown in <FIG>, the first connection end <NUM> is set to overlap with 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 two sides of the coil body <NUM>, respectively. The spanning segment <NUM> and the coil body <NUM> are arranged in different layers, and 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> may be arranged in the same layer as the bridge connecting the touch-control electrodes.

Optionally, as shown in <FIG>, the plurality of coils include a first coil 101e and a second coil 101f. Each of the first coil 101e and the second coil 101f is connected between the first connection end <NUM> and the second connection end <NUM>. A part of the first coil 101e is positioned on a side of the second coil 101f away from the center of the wireless communication structure, and a 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 millimeter-wave antenna unit <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. In this way, the lengths of the first coil 101e and the second coil 101f can be made similar or the same, so that the current 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 plurality of 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 arranged by the side of the direct-fed coil 101d and spaced apart from the direct-fed coil 101d. The coupled coil 101c being connected to the direct-fed coil 101d by coupling means that the coupled coil 101c does not have a direct connection relationship with other coils (including the direct-fed coil 101d) and the coupled coil 101c is for coupling with the direct-fed coil 101d to generate signals.

When the coil body <NUM> includes the coupled coil 101c and the direct-fed coil 101d, the millimeter-wave antenna unit <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 millimeter-wave antenna unit <NUM> is connected to the coupled coil 101c.

In these optional embodiments, when the wireless communication structure is used for 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 millimeter-wave antenna unit <NUM> is connected to the coupled coil 101c, so that the millimeter-wave antenna unit <NUM> is arranged closer to the edges of the display panel. For example, when the millimeter-wave antenna unit <NUM> is arranged in the touch-control layer <NUM>, the influence of the millimeter-wave antenna unit <NUM> on the touch-control effect of the touch-control layer <NUM> can be reduced. In addition, the millimeter-wave antenna unit <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 millimeter-wave antenna unit <NUM> on the display effect of the display panel.

In some other optional embodiments, as shown in <FIG>, the direct-fed coil 101d is positioned on the side of the coupled coil 101c away from the center of the wireless communication structure, and the millimeter-wave antenna unit <NUM> is connected to the direct-fed coil 101d. When the wireless communication structure is used for the display panel, the millimeter-wave antenna unit <NUM> is arranged closer to the edge of the display panel.

In addition, in an embodiment of the present application, by providing the coupled coil 101c, the performance of the loop structure <NUM> in transmitting and/or receiving wireless signals can be improved. For example, when the loop structure <NUM> is an NFC coil, the coupled coil 101c can improve the performance of the NFC coil in transmitting and/or receiving wireless signals in the NFC frequency band.

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> is positioned in the second area N, which can improve the influence of the loop structure <NUM> and the antenna <NUM> on the display effect of the display panel. And when the loop structure <NUM> and the antenna <NUM> are arranged in the touch-control layer <NUM>, the influence of the loop structure <NUM> and the antenna <NUM> on the touch-control effect can also be reduced. Optionally, the antenna <NUM> may be positioned in the second area N, or the antenna <NUM> may also be partially arranged in the first area M.

The second area N may be arranged in various manners. For example, the second area N may include a display area; and/or the second area N may include a non-display area. When the second area N includes a non-display area, the loop structure <NUM> is positioned in the non-display area, which can desirably reduce the influence of the loop structure <NUM> on the display effect and the touch-control 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 around the first area M in the second area N, which can increase an extension length of the loop structure <NUM> and 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 connection end <NUM> and the second connection end <NUM> are arranged close to each other. The coil body <NUM> extends around the first area M from the first connection end <NUM> and then is connected to the second connection end <NUM>. The distance between the first connection end <NUM> and the second connection end <NUM> is small, which not only facilitates the integration of a connector for transmitting signals from/to the first connection end <NUM> and a connector for transmitting signals from/to the second connection 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> is formed as extending along a winding path. A same coil body <NUM> includes a first extension segment 130a and a second extension segment 130b that overlap with each other in a direction approaching the edges of the wireless communication structure. In these optional embodiments, the coil body <NUM> extends along the winding path, and one part of the coil body <NUM> 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 millimeter wave antenna unit <NUM> is connected to the second extension segment 130b.

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

Optionally, when the antenna includes a plurality of millimeter-wave antenna arrays <NUM>, the wireless communication apparatus includes a plurality of second circuit boards <NUM> and a plurality of second integrated circuits <NUM>.

In some optional embodiments, the wireless communication apparatus 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>, which enables 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>, which enables the signal transmission between the second integrated circuit <NUM> and the PCB of the wireless communication apparatus.

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> is integrated with the second circuit board <NUM>, the first connection socket <NUM> is integrated with the second connection socket <NUM>, which can further simplify the structure of the wireless communication apparatus.

The third integrated circuit <NUM> is in communication with the non-millimeter-wave antenna <NUM>, so the third integrated circuit <NUM> is a non-millimeter-wave radio frequency integrated circuit. Because the non-millimeter-wave radio frequency integrated circuit and the NFC radio frequency integrated circuit have the filtering and frequency selectivity, 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 <NUM> is a non-NFC radio frequency integrated circuit.

For example, frequencies of non-millimeter waves commonly used in the mobile wireless communication are higher than <NUM>, that is to say, the millimeter wave antenna array <NUM> refers to an antenna array that transmits/receives wireless signals having frequencies higher than <NUM>.

For example, frequencies of non-millimeter waves commonly used in mobile wireless communication are higher than <NUM> and lower than <NUM>, that is to say, the non-millimeter wave antenna <NUM> refers to an antenna that transmits/receives wireless signals having frequencies higher than <NUM> and lower than <NUM>.
