DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Antennas are an important component of smart terminals, and the communication function of smart terminals is realized through antennas. When installing antennas, a certain clearance area must be secured to prevent other components from affecting the communication effect of the antenna. The large number of antennas required for 5G communication technology runs counter to the light, thin, small and beautiful design required for smart terminals such as smartphones. The clearance area of ​​the internal antenna of a mobile phone is insufficient, and mobile phone communication, especially high-frequency communication, is easily interfered with, which affects the communication effect. Therefore, it is a difficult task to arrange many antennas in a small mobile phone in order to improve the communication efficiency of smart terminals such as mobile phones.

[0010] Based on this, the embodiments of the present application provide a display panel and a display device that can solve the technical problem of lack of space for placing an antenna inside a smart terminal device.

[0011] 1 to 7, the display panel 100 has a first display region PL and a second display region BE, the second display region BE includes a first region BE1 and a second region BE2 provided adjacent to each other, a first antenna 120 is provided in the first region BE1, and a second antenna 130 is provided in the second region BE2. The display panel 100 further includes touch electrodes provided in the first display region PL and the second region BE2.

[0012] Specifically, depending on the shape of the display panel 100, the relative positions of the first display area PL and the second display area BE and their respective shapes also differ.

[0013] Exemplarily, the first display region PL may be rectangular, circular, elliptical, etc., and the second display region BE may be provided on the outer periphery of the first display region PL, or may be provided inside the first display region PL, and may be selected as necessary. When the second display region BE is provided on the outer periphery of the first display region PL, the second display region BE may be provided around the entire first display region PL, or may be provided around a part of the outer periphery of the first display region PL. Optionally, when the first display region PL is rectangular, the second display region BE may be provided on one side or multiple sides of the first display region PL.

[0014] Optionally, the first display area PL may be provided on a flat surface or a curved surface, and the second display area BE may be provided on a flat surface or a curved surface, and the specific shapes of the first display area PL and the second display area BE may be selected according to actual needs.

[0015] In some embodiments, as shown in Fig. 1, the first display area PL and the second display area BE may both be curved, and when a corresponding display panel 100 is applied to the display device, the display device is a curved display device or a flexible display device. In some embodiments, as shown in Fig. 2, the first display area PL and the second display area BE may both be flat, and when a corresponding display panel 100 is applied to the display device, the display device is a flat display device. In some embodiments, as shown in Fig. 4, the first display area PL is flat, and the second display area BE is curved, for example, the edge of the first display area PL is formed by folding, so that the objective of the present invention can still be achieved.

[0016] Optionally, the first display area PL may be foldable or non-foldable, and FIG. 3 shows an example in which the first display area PL of the display panel 100 is foldable.

[0017] The display panel 100 may be an organic light emitting diode (OLED) display panel 100 or a liquid crystal display (LCD) panel 100.

[0018] The first antenna 120 may be a patterned structure, and the second antenna 130 may be a patterned structure, and the patterns of the first antenna 120 and the second antenna 130 may be set according to actual needs, but the present application is not limited thereto.

[0019] The touch electrode 110a is provided in the second area BE2, that is, the second area BE2 has a touch function. The touch mode of the second area BE2 can be a self-capacitance mode or a mutual capacitance mode, and different touch modes correspond to different structure modes of the touch electrode 110a.

[0020] Referring to FIG. 6, in some embodiments, the touch mode of the second area BE2 is a mutual capacitance mode, in which case the touch electrodes 110a may be electrode blocks provided on multiple identical layers and distributed in an array, and the touch electrodes 110a in the same matrix row or the same matrix column may be electrically connected to each other.

[0021] In some other embodiments, the touch mode of the second region BE2 is a self-capacitance mode, in which case 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 extending along the row direction and the other extending along the column direction, and a capacitance may be generated at the intersection of the two.

[0022] 6, the second antenna 130 and the touch electrode 110a are provided in the second region BE2 of the second display region BE at the same time, that is, the second region BE2 has an antenna function and a touch function. The first region BE1 of the second display region BE has only the first antenna 120, and thus the first region BE1 has only an antenna function and no touch function, reducing the risk of the first region BE1 being touched incorrectly and affecting the antenna function of the first region BE1, and the first region BE1 has a sufficient space for the layout of the first antenna 120.

[0023] It should be noted that the second area BE2 may sample the antenna signal and the touch signal simultaneously or alternately. In some embodiments, a time division multiplexing method may be used to sample the antenna signal and the touch signal in the second area BE2 to avoid mutual interference between the two signals.

[0024] Specifically, the antenna signal and the touch signal can be adopted in the same time period, and as long as the sampling pulse width is narrow enough, a certain time gap remains between two sampling values ​​of the same kind of signal. If the sampling time of another signal is exactly within the time gap, the sampling values ​​of the two kinds of signals do not overlap in time. Optionally, the antenna signal and the touch signal can be adopted in the same time period. sampling The period can be set to any value between 1 μs and 10 ms and can be selected according to specific needs. By adopting such a control method to sample the antenna signal and the touch signal, the second antenna 130 and the touch electrode 110a share the same space, and the second area BE2 has both an antenna function and a touch function, and the two alternately collect signals, so that there is no signal interference between them.

[0025] The first antenna 120 is installed in the first area BE1 of the second display area BE, and the position of the first area BE1 in the display panel 100 is set according to the actual situation, so as to realize a high screen occupancy rate of the display panel 100, and the first area BE1 is only provided with the first antenna 120, which has only a signal receiving or transmitting function and does not have a touch function, thus providing a sufficient clearance section for the first antenna 120, improving the communication efficiency of the first antenna 120, and reducing the risk of erroneous contact. In addition, since only the first antenna 120 is provided in the first area BE1 and the touch electrode 110a is not provided, unlike the second antenna 130 and the touch electrode 110a alternately collecting antenna signals and touch signals, the first antenna 120 can continuously receive and transmit information, that is, the first antenna 120 can continuously realize the function of an antenna.

[0026] Optionally, the first antenna 120 and the second antenna 130 are both millimeter-wave antennas, and the first antenna 120 can be a main antenna and the second antenna 130 can be a sub-antenna, so as to enhance the signal of the first antenna 120. When the second antenna 130 is multiplexed to the touch electrode 110a, the first antenna 120 as the main antenna can also communicate independently.

[0027] In the display panel 100 according to the embodiment of the present application, the first antenna 120 is provided in the first region BE1 of the second display region BE, the second antenna 130 is provided in the second region BE2 of the second display region BE, and the touch electrode 110a is simultaneously provided in the second region BE2, that is, the antenna is integrated in the second display region BE of the display panel 100, so that the second display region BE can realize the display function and the antenna function, and there is no need to provide an antenna region separately, which is advantageous for realizing the thinning of the display panel 100 and the installation of a high screen occupancy rate. Here, by providing only the first antenna 120 in the first region BE1, the arrangement space of the first antenna 120 can be secured, and the risk of accidentally touching the first region BE1 and affecting the function of the first antenna 120 can be reduced. A second antenna 130 and a touch electrode 110a are provided in the second region BE2, that is, the second region BE2 can realize an antenna function and a touch function, so that the touch function of the second region BE2 is not affected, and the second region BE2 can be rationally utilized to better configure antenna integration, and the communication efficiency of the display panel 100 can be improved.

[0028] The number of the first area BE1 and the second area BE2 in the second display area BE may be selected according to need, and may be one each or multiple each, or multiple first areas BE1 or multiple second areas BE2 may be distributed alternately. The shapes and sizes of the multiple first areas BE1 may be the same or different, and may be provided according to actual needs.

[0029] In some embodiments, the second display area BE is provided in a stripe shape and extends along the edge of the first display area PL.

[0030] Specifically, the second display area BE may have stripes of different shapes depending on the edge shape of the first display area PL. For example, if the edge of the first display area PL is arc-shaped, the second display area BE has arc-shaped stripes, and if the edge of the second display area PL is linear, the second display area BE has linear stripes, i.e., the second display area BE extends linearly.

[0031] Optionally, the second display area BE may be planar or curved.

[0032] By providing the second display area BE at the edge of the first display area PL, it becomes easy to integrate the first antenna 120 and the second antenna 130 within the second display area BE, and by providing the first antenna 120 and the second antenna 130 using the striped second display area BE, the second display area BE combines antenna functions and display functions, making it easy to achieve a high screen occupancy rate of the display panel.

[0033] 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 at least two second areas BE2 are provided on both sides of the first area BE1, respectively.

[0034] Exemplarily, one first region BE1 and two second regions BE2 may be provided, and the two second regions BE2 may be located on both sides of the first region BE1 along the extension direction X. Two first regions BE1 may be provided, and three second regions BE2 may be provided, and the two first regions BE1 and the three second regions BE2 may be alternately distributed along the extension direction X. Of course, more first regions BE1 and second regions BE2 may be provided, and may be selected according to specific installation needs.

[0035] In this way, by making both ends of the second display area BE in the extending direction X into the second area BE2, it becomes easier for the operator to perform a touch operation on the second display area BE.

[0036] In some alternative embodiments, 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%.

[0037] Specifically, referring to FIG. 4, the second display area BE has one first area BE1 and two second areas BE2 located at both ends of the first area BE1 along the extension direction X. The first area BE1 has only an antenna function, and is not provided with a touch function or a touch-related device, while the second area BE2 has a touch function. Since there is no need to touch the first area BE1, the first area BE1 is provided at a position close to the middle of the second display area BE, which can further reduce the risk of accidentally touching the first area BE1. At the same time, the second area BE2 is provided at both ends of the second display area BE along its extension direction X, and the second area BE2 has a touch function, which makes it easier for an operator to touch the second area BE2.

[0038] For example, the first region BE1 is located in the middle of the second display region BE in the extension direction X, and the second regions BE2 at both ends have the same extension length in the extension direction X.

[0039] L2 / L1 may be 30%, 35%, 40%, 45%, or 50%, and may be, for example, a first region BE1 and second regions BE2 at both ends to divide the second display region BE into thirds. In this way, a sufficient space in the first region BE1 for providing the first antenna 120 in the second display region BE is ensured, reducing the risk that the operator will accidentally touch the first region BE1, and at the same time, when the second region BE2 has a touch function, it is possible to make it easier for the operator to touch the second region BE2 of the second display region BE.

[0040] The first antenna 120, the second antenna 130 and the touch electrode 110a may be provided in the same layer or in different layers, which may be selected according to specific needs. For example, the first antenna 120 and the second antenna 130 may be provided in the same layer, and the touch electrode 110a may be provided in a different layer.

[0041] In some embodiments, the second antenna 130 and the touch electrode 110a are provided in the same layer.

[0042] Specifically, referring to Figures 6 and 7, the display panel 100 includes a substrate 140 and a touch layer 110 provided on one side of the substrate 140, where the substrate 140 may include a light-emitting structure, a touch electrode 110a is provided on the touch layer 110, and a second antenna 130 is also provided on the touch layer 110; referring to Figures 9 and 10, an embodiment is shown in which the touch electrode 110a and the second antenna 130 are provided in the same layer.

[0043] According to the touch mode of the second area BE2, the display panel 100 may include one or more touch layers 110, the touch electrode 110a in the second area BE2 may be provided in two or more touch layers 110, and the second antenna 130 may be provided in any one of the film layers of the touch layer 110 and spaced apart from the touch electrode 110a or lead of the film layer, thereby reducing signal interference between them.

[0044] By providing the second antenna 130 and the touch electrode 110a in the same layer, and using the gap between the corresponding touch electrodes 110a in the touch layer 110 to install the second antenna 130, the touch function of the second area BE2 can be realized, or an electrical signal and an antenna function can be provided to realize the touch function, and at the same time, there is no need to install a film layer separately for the second antenna 130, and the thickness of the display panel 100 can be effectively reduced.

[0045] For example, when the touch mode of the second area BE2 is a self-capacitance mode, the touch layer 110 includes a touch driving electrode layer and a touch sensing electrode layer that are insulated from each other, and the second antenna 130 may be provided in the touch driving electrode layer or in the touch sensing electrode layer.

[0046] Optionally, the touch mode of the second area BE2 may be a mutual capacitance mode, in which case the touch layer 110 may include a touch electrode layer and a bridge layer, and the touch electrode 110a is provided in the touch electrode layer, in which case the second antenna 130 may be provided in the touch electrode layer.

[0047] With the above arrangement, both the touch function and the antenna function of the second area BE2 can be realized, and the thickness of the display panel 100 can be reduced.

[0048] In an embodiment in which the second antenna 130 and the touch electrode 110a are provided in the same layer, the first antenna 120, the second antenna 130 and the touch electrode 110a may be provided in the same layer or in different layers, either of which can realize the antenna function of the first area BE1.

[0049] In some embodiments, the first antenna 120 and the touch electrode 110a are disposed in the same layer, that is, the first antenna 120, the second antenna 130 and the touch electrode 110a are all disposed in the touch layer 110, so that the thickness of the display panel 100 can be further reduced.

[0050] Specifically, the touch electrode 110a is provided in the first display area PL and the second area BE2, and the first antenna 120 and the second antenna 130 are provided in the second display area BE, and the film layer of the second display area BE may be molded together with the film layer corresponding to the first display area PL. In this way, the thickness of the display panel 100 can be further reduced.

[0051] In some other embodiments, the display panel 100 includes a touch layer 110 and an antenna layer stacked together, the touch electrode 110a is disposed on the touch layer, and the second antenna 130 is disposed on the antenna layer.

[0052] That is, the touch electrode 110a and the second antenna 130 are provided on different layers, and may be located on adjacent film layers, or may be spaced apart by one or more film layers.

[0053] By providing the touch electrode 110a and the second antenna 130 on different film layers, the difficulty of processing the display panel 100 can be reduced, and the risk of short-circuiting between the second antenna 130 and the touch electrode 110a can be reduced.

[0054] In some embodiments, as shown in FIG. 8, the first antenna 120 includes at least one first antenna unit 121, and the second antenna 130 includes one or more second antenna units 131.

[0055] Optionally, the second antenna unit 131 in the second area BE2 and the touch electrode 110a may be structurally multiplexed, or both structures may be provided separately.

[0056] Specifically, the first antenna 120 may be connected to a first antenna terminal 173 via a first wiring 171 .

[0057] In some embodiments, at least some of the touch electrodes 110a in the second area BE2 are multiplexed to the second antenna unit 131.

[0058] The structure of the touch electrode 110a multiplexed to the second antenna unit 131 may be connected to the second antenna terminal 174 through the second wiring 172. The touch signal and the antenna signal in the second region BE2 can be sampled separately by time division multiplexing, so that the multiplexed structure of the touch electrode 110a and the second antenna unit 131 does not cause signal interference, and the multiplexed structure of both can further simplify the structure of the display panel 100. Optionally, the display panel 100 further includes a touch binding terminal, and the touch electrode 110a is connected to the touch binding terminal through a touch wiring, and a detailed description is omitted.

[0059] In some other embodiments, as shown in FIGS. 9 and 10 , the second antenna 130 includes a second antenna unit 131, and the second antenna unit 131 is spaced apart from the touch electrode 110a. Specifically, the second antenna unit 131 is spaced apart from and insulated from the conductive material constituting the touch electrode 110a.

[0060] For example, the touch method of the display panel 100 is a mutual capacitance method, and the touch electrodes 110a are distributed in an array on the same layer, and the touch electrodes 110a in the same matrix row or the same matrix column are electrically connected to each other. The second antenna unit 131 or the second antenna units 131 are electrically connected to each other to form an antenna pattern and realize the corresponding antenna function. When the second antenna unit 131 is spaced apart from the touch electrode 110a, the two are not mutually conductive and do not cause signal interference with each other. In this way, the second region BE2 can be realized to have both the touch function and the antenna function, and the thickness of the display panel 100 can be further reduced.

[0061] The second antenna unit 131 may be provided between two adjacent touch electrodes 110a, the second antenna unit 131 may be provided to surround the touch electrode 110a, or the touch electrode 110a may be provided to surround the second antenna unit 131.

[0062] In some alternative embodiments, with continued reference to FIGS. 9 and 10, at least a portion of the touch electrodes 110a are arranged to surround the second antenna unit 131.

[0063] Specifically, the second antenna units 131 are distributed in a row or a column, or the second antenna units 131 are distributed in a matrix, and at least some of the touch electrodes 110a are arranged to surround the second antenna units 131, that is, the second antenna units 131 are arranged inside the corresponding touch electrodes 110a.

[0064] Some of the touch electrodes 110a are arranged to surround the second antenna unit 131, thereby reducing the thickness of the display panel 100 and ensuring the touch sensitivity of the second area BE2 without interfering with the distribution pattern of the touch electrodes 110a.

[0065] The first antenna 120 and the second antenna 130 may be a long wave antenna, a medium wave antenna, a short wave antenna, a very short wave antenna or a microwave antenna, etc., respectively, and can be selected according to actual needs.

[0066] In some embodiments, the first antenna 120 and the second antenna 130 are both millimeter wave antennas, the first antenna 120 being a main antenna and the second antenna 130 being a sub-antenna for enhancing the signal of the first antenna.

[0067] Specifically, the functions realized by the first antenna 120 and the second antenna 130 are the same, and the second antenna 130 can enhance the efficiency of signal transmission of the first antenna 120, so that the corresponding antenna function has a better effect.

[0068] In some other 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 be one 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.

[0069] In some embodiments, the first antenna 120 is an NFC antenna, i.e., the first antenna 120 enables the near field communication function of the display device.

[0070] The type of the second antenna 130 may be the same as that of the first antenna 120, or may be different, and may be set according to actual needs.

[0071] In some embodiments, the second antenna 130 is an NFC antenna, that is, the second antenna 130 can enhance the near field communication signal of the display panel 100, and improve the efficiency of the near field communication of the display panel 100.

[0072] In some embodiments, the display panel 100 further includes an antenna layer, and the first antenna 120 and / or the second antenna 130 are disposed on the antenna layer.

[0073] That is, at least one of the first antenna 120 and the second antenna 130 is provided on the antenna layer and the other is provided on another film layer, or both the first antenna 120 and the second antenna 130 are provided on the antenna layer.

[0074] The antenna layer may be one layer or multiple layers, and when the antenna layer is one layer, the first antenna 120 and the second antenna 130 may both be provided in the antenna layer, or one of them may be provided in the antenna layer. When the antenna layer is multiple layers, the first antenna 120 and the second antenna 130 may be provided in different antenna layers, or may be provided in the same antenna layer.

[0075] By providing the antenna layer, the corresponding first antenna 120 and / or second antenna 130 can be easily installed, and the processing difficulty of the display panel 100 can be reduced.

[0076] In some embodiments, as shown in FIGS. 4 and 11 , the display panel 100 includes a substrate 140, an emissive layer and a polarizing layer 150 disposed in sequence on one side of the substrate 140, and the first antenna 120 is disposed on the polarizing layer 150.

[0077] That is, by integrating the first antenna 120 in the polarizing layer 150, there is no need to provide a separate film layer, and the thickness of the display panel 100 can be further reduced. Furthermore, by providing the first antenna 120 in the polarizing layer 150, signal interference between the first antenna 120 and related components of other film layers can be reduced, and the communication efficiency of the display panel 100 can be improved.

[0078] In an embodiment in which the first antenna 120 is disposed on the polarizing layer 150, the second antenna 130 may be disposed on the polarizing layer 150, or on another film layer, according to actual needs.

[0079] In some embodiments, the second antenna 130 is disposed on the polarizing layer 150. In this manner, the first antenna 120 and the second antenna 130 are integrated in the same film layer, which can further reduce the thickness of the display panel 100.

[0080] In some embodiments, with continued reference to Figures 4 and 11, the display panel 100 includes a substrate 140 and an emissive layer and an encapsulating layer 160 disposed in sequence on one side of the substrate 140, and the first antenna 120 is disposed on the encapsulating layer 160.

[0081] That is, in addition to integrating the first antenna 120 in the polarizing layer 150, the first antenna 120 may also be integrated in the encapsulation layer 160, which does not require a separate film layer and still reduces the thickness of the display panel 100. In addition, by providing the first antenna 120 in the encapsulation layer 160, it is still possible to reduce signal interference between the first antenna 120 and related components of other film layers, and improve the communication efficiency of the display panel 100.
