[0040] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced without some of these specific details. The description of the embodiments below is only intended to provide a better understanding of the present application by showing examples of the present application. In the drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessarily obscuring the present application; and, for clarity, the dimensions of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0041] In addition, for the sake of understanding and easy description, the dimensions and thicknesses of each configuration shown in the drawings are arbitrarily shown, but the concept of the present application is not limited thereto. In the drawings, for clarity, the thicknesses of layers, films, panels, and regions, etc. are enlarged. In the drawings, for better understanding and easy description, the thicknesses of some layers and regions are enlarged.

[0042] It can be understood that when an element such as a layer, a film, a region, or a substrate is described as being "on" another element, the element can be directly on the other element, or there may also be an intermediate element. In contrast, when an element is described as being "directly on" another element, there is no intermediate element. In addition, throughout the specification, the phrase "on" the target element means being positioned above or below the target element, and does not necessarily mean being positioned "on the upper side" based on the direction of gravity.

[0043] In addition, unless explicitly stated to the contrary, the word "comprising" will be understood to implicitly include the stated elements, but not to exclude any other elements.

[0044] An antenna is an important component in a smart terminal, and the communication function of the smart terminal is realized through the antenna. When setting up the antenna, a certain clearance area needs to be ensured to avoid other components affecting the communication effect of the antenna. However, the number of antennas required for 5G communication technology is relatively large, which runs counter to the increasingly demanding design of smart terminals such as smartphones for being light, thin, small and beautiful. The clearance area for the internal antenna of the mobile phone is insufficient, and the mobile phone communication, especially high-frequency communication, is easily interfered, affecting the communication effect. Therefore, how to arrange more antennas in a smaller mobile phone to improve the communication efficiency of smart terminals such as mobile phones is a difficult point.

[0045] Based on this, the embodiments of the present application provide a display panel and a display device, which can solve the technical problem of insufficient space for placing antennas inside smart terminal devices.

[0046] Such as Figures 1 to 4 respectively show the structural schematic diagrams of different display panels provided by the embodiments of the present application. Such as Figure 5 shows Figure 4 the front view of the display panel in Figure 6 shows a partial structural schematic diagram of a display panel provided by an embodiment of the present application. Figure 7 shows a partial structural schematic diagram of another display panel provided by an embodiment of the present application.

[0047] According to the display panel 100 provided by the embodiment of the present application, it has a first display area PL and a second display area BE. The second display area BE includes a first area BE1 and a second area BE2 arranged adjacent to each other. A first antenna 120 is provided in the first area BE1, and a second antenna 130 is provided in the second area BE2. The display panel 100 further includes touch electrodes provided in the first display area PL and the second area BE2.

[0048] Specifically, according to the different shapes of the display panel 100, the relative positions and respective shapes of the first display area PL and the second display area BE are also different.

[0049] Exemplarily, the first display area PL can be rectangular, circular or oval, etc. The second display area BE can be arranged on the periphery of the first display area PL or inside the first display area PL, and can be selected according to needs. When the second display area BE is arranged on the periphery of the first display area PL, the second display area BE can surround all of the first display area PL or surround a part of the periphery of the first display area PL. Optionally, when the first display area PL is rectangular, the second display area BE can be arranged on one side or multiple sides of the first display area PL.

[0050] Optionally, the first display area PL can be planar or curved, and the second display area BE can also be planar or curved. The specific shapes of the first display area PL and the second display area BE can be selected according to actual requirements.

[0051] In some embodiments, as Figure 1 shown, both the first display area PL and the second display area BE can be curved. When the corresponding display panel 100 is applied to a display device, the display device is a curved display device or a flexible display device. In other embodiments, as Figure 2 shown, both the first display area PL and the second display area BE can be planar. When the corresponding display panel 100 is applied to a display device, the display device is a flat display device. In some embodiments, as Figure 4 shown, the first display area PL is planar and the second display area BE is curved, for example, formed by bending the edge of the first display area PL. With such a setting, the inventive purpose of the present application can still be achieved.

[0052] Optionally, the first display area PL can be foldable or non-foldable. As Figure 3 shown, an example of the first display area PL of the display panel 100 being foldable is shown.

[0053] The display panel 100 can be an Organic Light Emitting Diode (OLED) display panel 100 or a Liquid Crystal Display (LCD) panel 100.

[0054] The first antenna 120 can be a patterned structure, and the second antenna 130 can also be a patterned structure. The patterns of the first antenna 120 and the second antenna 130 can be set according to actual requirements, and the present application does not limit this.

[0055] Touch electrodes 110a are arranged in the second area BE2, that is, the second area BE2 is set to have touch functionality. The touch form of the second area BE2 can be a self-capacitance form or a mutual-capacitance form. Different touch forms correspond to different structural forms of the touch electrodes 110a.

[0056] In some optional embodiments, the touch form of the second area BE2 is a mutual-capacitance form. At this time, the touch electrodes 110a can be a plurality of electrode blocks arranged in the same layer and distributed in an array, and the touch electrodes 110a in the same matrix row or the same matrix column are electrically connected to each other.

[0057] In some other alternative embodiments, the touch form of the second region BE2 is a self-capacitance form. At this time, the touch electrode 110a includes a touch driving electrode and a touch sensing electrode that are insulated from each other. One of the touch driving electrode and the touch sensing electrode extends in the row direction, and the other extends in the column direction. Capacitance can be generated at the intersection of the two.

[0058] In the second region BE2 of the second display area BE, the second antenna 130 and the touch electrode 110a are provided simultaneously. That is, while the second region BE2 has the antenna function, it also has the touch function. In the first region BE1 of the second display area BE, only the first antenna 120 is provided. In this way, the first region BE1 only has the antenna function and does not have the touch function, which can reduce the risk of false touch on the first region BE1 affecting the antenna function of the first region BE1, and also enables the first region BE1 to have sufficient space for arranging the first antenna 120.

[0059] It should be noted that when the second region BE2 samples the antenna signal and the touch signal, it can be sampled simultaneously or alternately. In some embodiments, in order to avoid mutual interference between the two signals, time-division multiplexing can be used to sample the antenna signal and the touch signal in the second region BE2.

[0060] Specifically, the antenna signal and the touch signal can be sampled according to the same time period. As long as the sampling pulse width is narrow enough, there will be a certain time gap between two sampling values of the same signal. If the sampling moment of the other signal happens to be within this time gap, the sampling values of the two signals will not overlap in time. Optionally, the sampling period of the antenna signal and the touch signal can be set to any value between 1 μs and 10 ms, and can be selected according to specific requirements. By using this control method to sample the antenna signal and the touch signal, the second antenna 130 and the touch electrode 110a can share the same space. While enabling the second region BE2 to have both the antenna function and the touch function, since the two signals are sampled alternately, they will not interfere with each other.

[0061] The first antenna 120 is disposed in the first area BE1 of the second display area BE. The position of the first area BE1 on the display panel 100 can be set according to actual conditions to achieve a higher screen-to-body ratio of the display panel 100. Moreover, only the first antenna 120 is disposed in the first area BE1, so that it only has the function of receiving or transmitting signals and does not have a touch function. With such a setting, a sufficient clearance area is provided for the first antenna 120, which can improve the communication efficiency of the first antenna 120 and reduce the risk of accidental touch. In addition, since only the first antenna 120 is disposed in the first area BE1 and no touch electrode 110a is provided, different from the second antenna 130 and the touch electrode 110a that alternately collect antenna signals and touch signals, the first antenna 120 can continuously receive and transmit information, that is, the first antenna 120 can continuously perform the function of an antenna.

[0062] Optionally, both the first antenna 120 and the second antenna 130 can be millimeter-wave antennas; the first antenna 120 can be a main antenna, and the second antenna 130 can be an auxiliary antenna to enhance the signal of the first antenna 120; when the second antenna 130 is multiplexed as the touch electrode 110a, the first antenna 120, i.e., the main antenna, can also communicate independently.

[0063] In the display panel 100 provided by the embodiment of the present application, by disposing the first antenna 120 in the first area BE1 of the second display area BE and the second antenna 130 in the second area BE2 of the second display area BE, and the second area BE2 is simultaneously provided with the touch electrode 110a, that is, the antennas are integrated in the second display area BE of the display panel 100. The second display area BE can not only realize the display function but also realize the antenna function, without the need to separately set an antenna area, which is beneficial to realizing the thinning and high screen-to-body ratio setting of the display panel 100. Among them, only the first antenna 120 is disposed in the first area BE1, ensuring the layout space of the first antenna 120 and reducing the risk of affecting the function of the first antenna 120 due to accidental touch of the first area BE1. And the second area BE2 is provided with both the second antenna 130 and the touch electrode 110a, that is, the second area BE2 can not only realize the antenna function but also realize the touch function. While not affecting the touch function of the second area BE2, the second area BE2 is reasonably utilized for better antenna integration setting to improve the communication efficiency of the display panel 100.

[0064] The number of the first area BE1 and the second area BE2 in the second display area BE is not limited. They can be one respectively, or multiple respectively. Multiple first area BE1s or multiple second area BE2s are distributed alternately. The shapes and sizes of multiple first area BE1s can be the same or different, and are set according to actual needs.

[0065] In some alternative embodiments, the second display area BE is arranged in a strip shape and extends along the edge of the first display area PL.

[0066] Specifically, according to the different shapes of the edge of the first display area PL, the second display area BE can be in strip shapes of different shapes. For example, if the edge of the first display area PL is arc-shaped, the second display area BE is in an arc-shaped strip; if the edge of the second display area PL is linear, the second display area BE is in a straight strip, that is, the second display area BE extends linearly.

[0067] Optionally, the second display area BE can be flat or curved.

[0068] It can be understood that arranging the second display area BE at the edge of the first display area PL facilitates the integration of the first antenna 120 and the second antenna 130 in the second display area BE, and arranging the first antenna 120 and the second antenna 130 by using the strip-shaped second display area BE enables the second display area BE to have both an antenna function and a display function, facilitating the realization of a high screen-to-body ratio of the display panel.

[0069] In some embodiments, in the extension direction X of the second display area BE, the first area BE1 is located at the middle position of the corresponding second display area BE, and the second areas BE2 are respectively arranged on both sides of the first area BE1.

[0070] Exemplarily, one first area BE1 can be arranged, and two second areas BE2 are respectively arranged on both sides of the first area BE1 along the extension direction X. Two first areas BE1 can also be arranged, and three second areas BE2 are arranged. The two first areas BE1 and the three second areas BE2 are distributed alternately along the extension direction X. Of course, more first areas BE1 and second areas BE2 can also be arranged, which can be selected according to specific setting requirements.

[0071] With such an arrangement, the two ends of the second display area BE along the extension direction X are the second areas BE2. The implementation manner in which the two ends of the second display area BE in the extension direction X are set as the second areas BE2 is more convenient for the operator to perform touch operations on the second display area BE.

[0072] In some alternative implementation manners, the extension length of the second display area BE is L1, and the length of the first area BE1 along the extension direction X of the second display area BE is L2, where 30% ≤ L2 / L1 ≤ 50%.

[0073] Specifically, the second display area BE has a first area BE1 and two second areas BE2 located at both ends of the first area BE1 along the extension direction X. Since the first area BE1 only has an antenna function and does not have a touch function or touch-related components, while the second area BE2 has a touch function, and since no touch operation is required for the first area BE1, the first area BE1 is set at a position closer to the middle of the second display area BE, further reducing the risk of accidental touch on the first area BE1. At the same time, the second area BE2 is set at both ends of the second display area BE along its own extension direction X. Since the second area BE2 has a touch function, it is more convenient for the operator to perform touch operations on the second area BE2.

[0074] Exemplarily, the first area BE1 is located exactly in the middle of the second display area BE along the extension direction X, and the second areas BE2 at both ends have the same extension length along the extension direction X.

[0075] L2 / L1 can be 30%, 35%, 40%, 45% or 50%, etc. Exemplarily, the first area BE1 and the second areas BE2 at both ends can be set to trisect the second display area BE. Such a setting can ensure that there is enough space for the first area BE1 where the first antenna 120 is arranged in the second display area BE, reduce the risk of accidental touch on the first area BE1 by the operator, and at the same time, when the second area BE2 has a touch function, it is further convenient for the operator to perform touch operations on the second area BE2 of the second display area BE.

[0076] The first antenna 120, the second antenna 130 and the touch electrode 110a can be arranged on the same layer or on different layers, and can be selected according to specific requirements. Exemplarily, the first antenna 120 and the second antenna 130 can be arranged on the same layer, while being on a different layer from the touch electrode 110a.

[0077] Figure 7 shows a cross-sectional structural schematic diagram along the A-A direction in an embodiment Figure 4 along the A-A direction.

[0078] In some alternative embodiments, the second antenna 130 and the touch electrode 110a are arranged on the same layer.

[0079] Specifically, the display panel 100 includes a substrate 140 and a touch layer 110 provided on one side of the substrate 140. The substrate 140 may include a light-emitting structure. The touch electrode 110a is provided on the touch layer 110, and the second antenna 130 is also provided on the touch layer 110.

[0080] According to different touch forms of the second area BE2, the display panel 100 may include one or more touch layers 110. The touch electrodes 110a in the second area BE2 may be disposed in two or more touch layers 110. The second antenna 130 may be disposed in any one film layer of the touch layer 110 and is spaced apart from the touch electrodes 110a or leads of the film layer to reduce signal interference therebetween.

[0081] It can be understood that by arranging the second antenna 130 in the same layer as the touch electrodes 110a, the second antenna 130 can be arranged by using the gaps between the corresponding touch electrodes 110a in the touch layer 110. While realizing the touch function of the second area BE2 or providing electrical signals and antenna functions for realizing the touch function, there is no need to separately provide a film layer for the second antenna 130, effectively reducing the thickness of the display panel 100.

[0082] Exemplarily, when the touch form of the second area BE2 is the self - capacitance form, the touch layer 110 includes a touch driving electrode layer and a touch sensing electrode layer which are insulated from each other. The second antenna 130 may be disposed in the touch driving electrode layer or may be disposed in the touch sensing electrode layer.

[0083] Optionally, the touch form of the second area BE2 may also be the mutual - capacitance form. At this time, the touch layer 110 may include a touch electrode layer and a bridging layer, wherein the touch electrodes 110a are disposed in the touch electrode layer. At this time, the second antenna 130 may be disposed in the touch electrode layer.

[0084] Through the above - mentioned arrangements, the touch function and antenna function of the second area BE2 can be realized, and at the same time, the thickness of the display panel 100 is reduced.

[0085] In an embodiment where the second antenna 130 is disposed in the same layer as the touch electrodes 110a, the first antenna 120 and the second antenna 130 and the touch electrodes 110a may be disposed in the same layer or in different layers, and the antenna function of the first area BE1 can be realized.

[0086] In some alternative embodiments, the first antenna 120 is also disposed in the same layer as the touch electrodes 110a. That is to say, the first antenna 120, the second antenna 130, and the touch electrodes 110a are all disposed in the touch layer 110, further reducing the thickness of the display panel 100.

[0087] Specifically, the touch electrodes 110a are disposed in the first display area PL and in the second area BE2, and the first antenna 120 and the second antenna 130 are disposed in the second display area BE. Then, the film layer of the second display area BE and the film layer corresponding to the first display area PL can be formed together. Such an arrangement can further reduce the thickness of the display panel 100.

[0088] In some other alternative embodiments, the display panel 100 includes a touch layer 110 and an antenna layer disposed in a stacked manner. The touch electrodes 110a are disposed on the touch layer, and the second antenna 130 is disposed on the antenna layer.

[0089] That is to say, the touch electrodes 110a and the second antenna 130 are disposed in different layers, and may be located in adjacent film layers, or may be separated by one or more film layers.

[0090] It can be understood that disposing the touch electrodes 110a and the second antenna 130 in different film layers can reduce the processing difficulty of the display panel 100 and reduce the risk of short circuit between the second antenna 130 and the touch electrodes 110a.

[0091] In some embodiments, as Figure 8 shown, the first antenna 120 includes a first antenna unit 121, and the second antenna 130 includes one or more second antenna units 131.

[0092] Optionally, the second antenna units 131 in the second region BE2 and the touch electrodes 110a may be structurally multiplexed, or the structures of the two may be separately provided.

[0093] Specifically, the first antenna 120 may be connected to the first antenna terminal 173 through the first trace 171.

[0094] In some embodiments, at least part of the touch electrodes 110a in the second region BE2 are multiplexed as the second antenna units 131.

[0095] The structure of the touch electrodes 110a multiplexed as the second antenna units 131 may be connected to the second antenna terminal 174 through the second trace 172. Since the touch signals and the antenna signals in the second region BE2 can be separately sampled by time-division multiplexing, the multiplexed structure of the touch electrodes 110a and the second antenna units 131 will not cause signal interference, and the multiplexed structure of the two can further simplify the structure of the display panel 100. Optionally, the display panel 100 further includes touch bonding terminals, and the touch electrodes 110a are connected to the touch bonding terminals through touch traces, which will not be elaborated herein.

[0096] In some other alternative embodiments, as Figure 9 and Figure 10 shown, the second antenna 130 includes second antenna units 131, and the second antenna units 131 are spaced apart from the touch electrodes 110a. Specifically, it means that the second antenna units 131 and the conductive material constituting the touch electrodes 110a are spaced apart and insulated from each other.

[0097] Exemplarily, the touch form of the display panel 100 is mutual capacitance type, and a plurality of touch electrodes 110a are arranged in a same-layer array, and the touch electrodes 110a in the same matrix row or the same matrix column are electrically connected to each other. One of the second antenna units 131 or a plurality of second antenna units 131 are electrically connected to form an antenna pattern to achieve corresponding antenna functions. The second antenna unit 131 and the touch electrode 110a are arranged at intervals, so that the two do not conduct electricity with each other, and thus do not generate signal interference with each other. With such an arrangement, while the second region BE2 has both touch function and antenna function, the thickness of the display panel 100 is further reduced.

[0098] It can be understood that the second antenna unit 131 can be arranged between two adjacent touch electrodes 110a, the second antenna unit 131 can be arranged around the touch electrode 110a, or the touch electrode 110a can be arranged around the second antenna unit 131.

[0099] In some optional embodiments, please continue to refer to Figure 9 and Figure 10 , at least some of the touch electrodes 110a are arranged around the second antenna unit 131.

[0100] Specifically, the second antenna unit 131 is distributed in a row or a column, or the second antenna unit 131 is distributed in a matrix, and at least some of the touch electrodes 110a are arranged around the second antenna unit 131, that is, the second antenna unit 131 is arranged inside the corresponding touch electrode 110a.

[0101] It can be understood that arranging some of the touch electrodes 110a around the second antenna unit 131 can reduce the thickness of the display panel 100 without disturbing the distribution pattern of the touch electrodes 110a, so as to ensure the touch sensitivity of the second region BE2.

[0102] The first antenna 120 and the second antenna 130 can be a long-wave antenna, a medium-wave antenna, a short-wave antenna, an ultrashort-wave antenna, a microwave antenna, etc., and can be selected according to actual needs.

[0103] In some embodiments, both the first antenna 120 and the second antenna 130 are millimeter-wave antennas, the first antenna 120 is the main antenna, and the second antenna 130 is the auxiliary antenna and is used to enhance the signal of the first antenna.

[0104] Specifically, the functions realized by the first antenna 120 and the second antenna 130 are the same, and the second antenna 130 can increase the efficiency of signal transmission of the first antenna 120, so that the corresponding antenna function has a better effect.

[0105] In some other alternative embodiments, the first antenna 120 and the second antenna 130 may both be non-millimeter wave antennas, and the first antenna 120 and the second antenna 130 may specifically form one or two or more of a Bluetooth antenna, a wireless network communication technology (Wi-Fi) antenna, a Global Positioning System (GPS) antenna, a Near Field Communication (NFC) antenna, and a Laser-Direct-structuring (LDS) antenna.

[0106] In some alternative embodiments, the first antenna 120 is an NFC antenna. That is, the near field communication function of the display device is implemented through the first antenna 120.

[0107] The second antenna 130 may be of the same type as the first antenna 120 or different, and there is no limitation here.

[0108] In some embodiments, the second antenna 130 is an NFC antenna. That is, the near field communication signal of the display panel 100 is enhanced through the second antenna 130, and the efficiency of the near field communication of the display panel 100 is increased.

[0109] In some embodiments, the display panel 100 further includes an antenna layer, and the first antenna 120 and / or the second antenna 130 is disposed on the antenna layer.

[0110] That is to say, at least one of the first antenna 120 and the second antenna 130 is disposed on the antenna layer, and the other is disposed on other film layers, or both the first antenna 120 and the second antenna 130 are disposed on the antenna layer.

[0111] The antenna layer may be one layer or multiple layers. When the antenna layer is one layer, both the first antenna 120 and the second antenna 130 may be disposed on the antenna layer, or one of them may be disposed on the antenna layer. When the antenna layer is multiple layers, the first antenna 120 and the second antenna 130 may be disposed on different antenna layers or on the same antenna layer.

[0112] The provision of the antenna layer facilitates the provision of the corresponding first antenna 120 and / or the second antenna 130 and reduces the processing difficulty of the display panel 100.

[0113] In some embodiments, as Figure 4 and Figure 11 shown, the display panel 100 includes a substrate 140, a light-emitting layer and a polarizer layer 150 sequentially disposed on one side of the substrate 140, and the first antenna 120 is disposed on the polarizer layer 150.

[0114] That is to say, the first antenna 120 is integrated into the polarizing layer 150 without separately providing a film layer, further reducing the thickness of the display panel 100. Moreover, the solution of arranging the first antenna 120 in the polarizing layer 150 can reduce the signal interference between the first antenna 120 and the components related to other film layers, improving the communication efficiency of the display panel 100.

[0115] In the embodiment where the first antenna 120 is arranged in the polarizing layer 150, the second antenna 130 can be arranged in the polarizing layer 150 or in other film layers, without limitation here.

[0116] In some alternative embodiments, the second antenna 130 is arranged in the polarizing layer 150. In this way, the first antenna 120 and the second antenna 130 are integrated in the same film layer, further reducing the thickness of the display panel 100.

[0117] In some embodiments, please continue to refer to Figure 4 and Figure 11 , the display panel 100 includes a substrate 140, a light-emitting layer and a packaging layer 160 sequentially arranged on one side of the substrate 140, and the first antenna 120 is arranged in the packaging layer 160.

[0118] That is to say, in addition to integrating the first antenna 120 into the polarizing layer 150, the first antenna 120 can also be integrated into the packaging layer 160 without separately providing a film layer, still reducing the thickness of the display panel 100. Moreover, the solution of arranging the first antenna 120 in the packaging layer 160 can still reduce the signal interference between the first antenna 120 and the components related to other film layers, improving the communication efficiency of the display panel 100.

[0119] In some alternative embodiments, the second antenna 130 is arranged in the packaging layer 160. In this way, the film layer thickness of the display panel 100 can still be reduced.

[0120] In the embodiment where the display panel 100 is provided with both a polarizing layer 150 and a packaging layer 160, the polarizing layer 150 is arranged on one side of the substrate 140, and the packaging layer 160 is arranged on the side of the polarizing layer 150 away from the substrate 140. At this time, the first antenna 120 and the second antenna 130 can be arranged in the packaging layer 160, can be arranged in the polarizing layer 150, or one of them is arranged in the packaging layer 160 and the other is arranged in the polarizing layer 150, without limitation here.

[0121] The polarizing layer 150 being arranged on one side of the substrate 140 does not mean that the polarizing layer 150 is directly arranged on the surface of the substrate 140. Other film layers can be arranged between the polarizing layer 150 and the substrate 140. Other film layers can also be arranged between the packaging layer 160 and the polarizing layer 150.

[0122] In some alternative embodiments, please continue to refer to Figure 4 and Figure 11 , the display panel 100 includes an array substrate 170 and a light-emitting layer sequentially disposed on one side of the substrate 140, and the first antenna 120 and / or the second antenna 130 is disposed on the array substrate 170. That is, at least one of the first antenna 120 and the second antenna 130 is integrated in the array substrate 170 of the display panel 100. With such an arrangement, the purpose of reducing the thickness of the display panel 100 can still be achieved.

[0123] In some alternative embodiments, the array substrate 170 includes a metal layer, and the first antenna 120 and / or the second antenna 130 is disposed on the metal layer. That is, at least one of the first antenna 120 and the second antenna 130 is disposed on the metal layer. It can be understood that the array substrate 170 includes at least two metal layers, and the first antenna 120 and the second antenna 130 can be disposed on the same metal layer or different metal layers.

[0124] According to the different structural forms of the display panel 100, the display panel 100 can be provided with one second display area BE or multiple second display areas BE. In the embodiment where the display panel 100 is provided with multiple second display areas BE, the multiple second display areas BE can be adjacent to each other or spaced apart. Exemplarily, two second display areas BE of the display panel 100 are disposed on opposite sides of the first display area PL, that is, the two second display areas BE are disposed in parallel.

[0125] In the embodiment where the display panel 100 is provided with multiple second display areas BE, the first antenna 120 and the second antenna 130 can be provided in each second display area BE, or the first antenna 120 and the second antenna 130 can be provided in some second display areas BE, which can be selected according to specific requirements.

[0126] In some alternative embodiments, the display panel 100 includes at least two second display areas BE, and a first area BE1 and a second area BE2 are formed in at least one of the second display areas BE.

[0127] Specifically, at least one of the second display areas BE includes a first area BE1 and a second area BE2. The first area BE1 is provided with the first antenna 120, and the second area BE2 is provided with the second antenna 130 and the touch electrode 110a. The other second display areas BE can only have a display function or can also have both a display function and a touch function.

[0128] By disposing a first antenna 120 and a second antenna 130 in at least one second display area BE, the first antenna 120 and the second antenna 130 can be disposed in multiple second display areas BE according to actual needs, providing sufficient space for the setting of the first antenna 120 and the second antenna 130, and further improving the communication efficiency of the display panel 100.

[0129] As Figure 4 shown, in some embodiments, the first display area PL is set as a flat display area, and the second display area BE is set as a bent display area.

[0130] Specifically, after the bent display area and the flat display area are integrally formed, the bent display area can be formed by bending the edge of the flat display area. By disposing the first antenna 120 and the second antenna 130 in the bent display area and using the positions of the bent display area to respectively dispose the first antenna 120 and the second antenna 130, it is not necessary to occupy the position space of the flat display area or the non-display area, which is beneficial to improving the screen occupation ratio of the display panel 100.

[0131] In some embodiments, the display panel 100 includes at least two bent display areas, and at least one of the bent display areas is set to form a first area BE1 and a second area BE2. That is to say, the first area BE1 and the second area BE2 can be formed in one bent display area or can be respectively formed in different bent display areas. In this way, it is convenient to reasonably set the positions of the first antenna 120 and the second antenna 130 according to actual needs.
