The display panel includes a touch module 200, and the touch module 200 is disposed in the non-display area NA. 210 , the signal line may be touch wiring 210. In some other embodiments, the signal line may be another signal line, such as a ground line.

[0014] The winding area is located between the display area AA and the outer edge of the non-display area. The width of the winding area refers to the distance between the farthest part of the signal line from the display area AA and the display area AA, that is, the width of the winding area refers to the maximum distance between the signal line and the display area AA. When the winding area is formed by the touch wiring 210, the width of the winding area refers to the maximum distance between the orthogonal projection of the touch wiring 210 on the substrate and the display area AA. When the winding area is formed by the array wiring, the width of the winding area refers to the maximum distance between the orthogonal projection of the array wiring on the substrate and the display area AA. When the winding area is formed by both the touch wiring 210 and the array wiring, the width of the winding area refers to the maximum distance between the orthogonal projection of the signal line (including the touch wiring and the array wiring) on ​​the substrate and the display area AA.

[0015] In the display panel according to the embodiment of the present application, the display panel includes a substrate 100 and an antenna module 300 disposed on the substrate 100. At least one antenna module on the substrate 300The orthogonal projection of the antenna module 300 is provided in a winding region formed in the non-display area NA, and it is not necessary to secure a separate installation space for the antenna module 300, and it is possible to reduce the space occupied by the antenna module 300 and further reduce the size of the non-display area NA. When the display panel is used in a display device, it is possible to reduce the size of the frame of the display device and improve the screen occupancy rate.

[0016] In some optional embodiments, referring to FIGS. 1 to 3 , the display panel further includes a touch module 200 arranged on one side of the substrate 100, the touch module 200 includes a plurality of touch wirings 210 located in the non-display area NA, the winding area includes a touch winding area formed by wiring the touch wirings 210 in the non-display area NA, and a positive projection of at least one antenna module 300 on the substrate is located in the touch winding area.

[0017] Here, the distance from the edge of the touch winding area away from the display area AA to the display area AA is the same, i.e., the touch winding area is provided with an equal width. The width of the touch winding area refers to the distance from the part of the touch wiring 210 farthest from the display area AA to the display area AA, i.e., the width of the touch winding area refers to the maximum distance between the touch wiring 210 and the display area AA.

[0018] Optionally, the antenna module 300 is provided on the substrate 100. The touch module 200 and the antenna module 300 are provided on the substrate 100, which does not mean that the touch module 200 and the antenna module 300 are directly provided on the surface of the substrate 100, but means that another film layer may be provided between the touch module 200 and the substrate 100, or another film layer may be provided between the antenna module 300 and the substrate 100.

[0019] In the display panel according to the embodiment of the present application, the display panel includes a substrate 100, and a touch module 200 and an antenna module 300 disposed on the substrate. The orthogonal projection of at least one antenna module 300 on the substrate is located within a touch winding area formed in the non-display area NA by the touch wiring 210, which does not require a separate installation space for the antenna module 300, and can reduce the space occupied by the antenna module 300 and the touch module 200 together, and further reduce the size of the non-display area NA.

[0020] Optionally, the orthogonal projection of at least one antenna module 300 on the substrate is located within an array winding area in which the array wiring is formed in the non-display area NA, so that there is no need to secure additional installation space for the antenna module 300, and the space occupied by both the antenna module 300 and the array wiring can be reduced, and the size of the non-display area NA can be reduced. When the display panel is used in a display device, the size of the frame in the display device can be reduced, and the screen occupancy rate can be improved.

[0021] In some embodiments, the touch module 200 further includes an electrode block 220 located in the display area AA, and the orthogonal projection of at least one antenna module 300 on the substrate 100 is located between the orthogonal projections of two adjacent touch wirings 210 on the substrate 100, and / or the orthogonal projection of at least one antenna module 300 on the substrate 100 is located between the orthogonal projections of the electrode block 220 and the touch wiring 210 on the substrate.

[0022] 1 and 2, the orthogonal projection of at least one antenna module 300 on the substrate 100 may be located in an included angle region between the orthogonal projection of the electrode block 220 on the substrate 100 and the orthogonal projection of some of the touch wirings 210 on the substrate 100, or the orthogonal projection of at least one antenna module 300 on the substrate 100 may be located between the orthogonal projection of two adjacent touch wirings 210 on the substrate 100, in which case, the orthogonal projection of at least one antenna module 300 on the substrate 100 and the orthogonal projection of at least some of the touch wirings 210 on the substrate 100 are distributed at intervals along the circumferential direction of the display area AA. That is, the orthogonal projection of at least one antenna module 300 on the substrate 100 and the orthogonal projection of at least some of the touch wirings 210 on the substrate 100 are distributed at intervals along the extension direction of the edge of the display area AA.

[0023] There are several installation methods of the antenna module 300, and referring to Fig. 2, the antenna module 300 includes a radiation electrode 310, a ground end 320 and a transmission end 330 provided on the radiation electrode 310, the transmission end 330 and the radiation electrode 310 are electrically connected to each other, and the transmission end 330 is used for transmitting signals. Optionally, two ground ends 320 are provided on the same antenna module 300, and the two ground ends 320 are provided on both sides of the transmission end 330, respectively.

[0024] Optionally, the display panel may further include a ground wire 900, and the antenna module 300 may be connected to the ground wire 900. For example, the ground end 320 of the antenna module 300 is connected to the ground wire 900. Optionally, the ground wire 900 is arranged to surround the display area AA. Optionally, the ground ends 320 of the multiple antenna modules 300 are connected to the same ground wire 900. Optionally, the orthogonal projection of the antenna module 300 on the substrate 100 is located between the ground wire 900 and the display area AA, that is, the antenna module 300 is located within a winding area formed by the ground wire 900 to surround the display area AA.

[0025] In some optional embodiments, referring to Figures 1 to 4, the display panel further includes a touch pad 400 located in the non-display area NA, the touch wiring 210 includes a first connection segment 211, a second connection segment 213, and a wiring segment 212 located between the first connection segment 211 and the second connection segment 213, the electrode block 220 includes a touch electrode block 221, the first connection segment 211 is connected to the touch electrode block 221, and the second connection segment 213 is connected to the touch pad 400.

[0026] Next, referring to Figures 2 to 4, in some optional embodiments, the orthogonal projections of at least a portion of the antenna modules 300 on the substrate 100 are located between the orthogonal projections of two adjacent first connection segments 211 and / or second connection segments 213 on the substrate 100.

[0027] Two adjacent first connection segments 211 and / or two adjacent second connection segments 213 mean two adjacent first connection segments 211, or two adjacent second connection segments 213, or two adjacent first connection segments 211 and two adjacent second connection segments 213.

[0028] In these optional embodiments, a corner area is generally formed between the first connection segment 211 and the wiring segment 212, and corner areas are also formed between the wiring segment 212 and the second connection segment 213. The size of the corner area is large, and by installing the antenna module 300 in this area, the impact of the antenna module 300 on the touch wiring routing can be reduced.

[0029] In some optional embodiments, the orthogonal projection of at least one antenna module 300 on the substrate 100 is located between the display area AA and the orthogonal projection of the wiring segment 212 on the substrate 100, i.e., the orthogonal projection of at least one antenna module 300 on the substrate is located in the touch winding area, thereby further reducing the frame area size of the display panel.

[0030] In some selectable embodiments, the electrode block 220 further includes at least one spacer electrode block 222 located between the touch electrode blocks 221 corresponding to at least some of the adjacent two first connection segments 211, and the orthogonal projection of at least some of the antenna modules 300 on the substrate 100 is located on the non-display area AA side of the at least one spacer electrode block 222. The touch electrode blocks 221 corresponding to the adjacent two first connection segments 211 refer to the touch electrode blocks 221 connected to each of the adjacent two first connection segments 211.

[0031] In these selectable embodiments, by adjusting the routing of the touch wiring 210, at least one spacer electrode block 222 can be formed between the touch electrode blocks 221 corresponding to two adjacent first connection segments 211. Since the touch wiring 210 is not provided on the spacer electrode block 222 on the side where the two adjacent first connection segments 211 are located, the space corresponding to the two adjacent first connection segments 211 of the spacer electrode block 222 is large, and a sufficient arrangement space can be provided for the antenna module 300.

[0032] In some optional embodiments, the orthogonal projection of at least a portion of the antenna module 300 on the substrate 100 is located between the orthogonal projection of at least one spacer electrode block 222 on the substrate 100 and the orthogonal projection of the wiring segment 212 on the substrate 100, so that the installation of the antenna module 300 does not affect the wiring of the wiring segment 212.

[0033] Optionally, the multiple first connection segments 211 are spaced apart from each other along the circumferential direction to surround the display area AA. A gap for installing the antenna module 300 can be formed between two adjacent first connection segments 211 in the circumferential direction.

[0034] Optionally, still referring to Figures 1 to 4, the touch pad 400 is provided on one side of the display area AA in the first direction Y, and the multiple touch pads 400 are provided side by side in the second direction X. Thus, the multiple second connection segments 213 are provided side by side in the second direction X, and the multiple second connection segments 213 are located on one side of the display area AA in the first direction Y.

[0035] Optionally, the non-display area NA includes a first sub-area NA1 and a second sub-area NA2 arranged opposite each other along a first direction Y, the touch pad 400 and the second connecting segment 213 are located in the second sub-area NA2, and the multiple second connecting segments 213 are arranged side by side in the second direction X, thereby forming regular gaps between adjacent second connecting segments 213.

[0036] Optionally, there are a plurality of touch electrode blocks 221, and each touch electrode block 221 is connected to a first connection segment 211. Each touch electrode block 221 is located at a different position in the display area AA, and a plurality of first connection segments 211 are distributed at intervals on the periphery of the display area AA to connect each touch electrode block 221. As shown in FIG. 1, in the direction from the second sub-area NA2 to the first sub-area NA1, the number of touch wirings 210 gradually decreases, and the number of wiring segments 212 gradually decreases, so that the gap between two adjacent first connection segments 211 gradually increases. At least one antenna module 300 is provided corresponding to the gap between two adjacent first connection segments 211 with a large gap, thereby reducing the influence of the antenna module 300 on the routing of the touch wiring 210.

[0037] 1 and 4, the wiring segments 212 are provided to surround the display area AA. The lengths of the wiring segments 212 are different. For example, when the distance between the first connection segment 211 and the second connection segment 213 is short, the distance between the wiring segments 212 is short. Since the touch pad 400 is provided in the second sub-area NA2, the number of wiring segments 212 increases toward the second sub-area NA2. Therefore, the number of wiring segments 212 and the first connection segments 211 decreases on the side away from the second sub-area NA2. As a result, a gap may exist between the adjacent first connection segments 211 or between the display area AA and the wiring segments 212.

[0038] In some alternative embodiments, still referring to Fig. 1, the non-display area NA includes a first sub-area NA1 and a second sub-area NA2 arranged opposite to each other in a first direction Y, the second connecting segment 213 is located in the second sub-area NA2, and the antenna module 300 is located in the first sub-area NA1. In Fig. 1, the first sub-area NA1 and the second sub-area NA2 are shown in a rectangular dashed line frame, but the dashed line does not limit the structure of the embodiment of the present application, and the dashed line only indicates the location of the first sub-area NA1 and the second sub-area NA2, and the first sub-area NA1 and the second sub-area NA2 are the non-display area NA within the dashed line rectangular frame.

[0039] In these alternative embodiments, when the second connection segment 213 is located in the second sub-region NA2, the closer to the second sub-region NA2, the denser the wiring segments 212 are, and the smaller the gap between the wiring segments 212 and the display region AA is. The farther from the second sub-region NA2, the sparser the wiring segments 212 are, and the larger the gap between the wiring segments 212 and the display region AA is, and the larger the interval between two adjacent first connection segments 211 is. If the antenna module 300 is installed in the first sub-region NA1, more installation space can be secured for the antenna module 300, which facilitates the arrangement of the antenna module 300, and the density of the metal wiring in the first sub-region NA1 and the metal wiring in the second sub-region NA2 can be more consistent, improving the consistency of the wiring density in the display panel.

[0040] There are multiple installation forms for the first sub-region NA1. For example, the first sub-region NA1 is an elongated structure extending along the second direction X, i.e., the first sub-region NA1 is located on one side of the display area AA in the first direction Y, and the antenna module 300 is provided on one side of the display area AA in the first direction Y.

[0041] In some alternative embodiments, still referring to FIG. 1, the first sub-area NA1 includes a first segment NA11 and a second segment NA12 that intersect, the first segment NA11 being located on one side of the display area AA in a first direction Y, and the second segment NA12 being located on at least one side of the display area AA in a second direction X. The antenna module 300 is located in the first segment NA11 and / or the second segment NA12. In FIG. 1, only one second segment NA12 is shown. Optionally, two second segments NA12 are located on both sides of the display area AA in the second direction X.

[0042] Optionally, the antenna module 300 is located on the side of the first segment NA11 close to the second segment NA12, and / or the antenna module 300 is located on the side of the second segment NA12 close to the first segment NA11. That is, the antenna module 300 is provided adjacent to a corner region of the non-display area NA. In these optional embodiments, the first sub-area NA1 is located in a corner region of the display panel. Generally, the density of the touch wiring 210 is low in this area, and the gap between the wiring segment 212 and the display area AA is large, so that more installation space can be secured for the antenna module 300.

[0043] Optionally, the number of first sub-regions NA1 is two, the two first sub-regions NA1 are distributed at intervals along the second direction X, and the second segments NA12 of the two first sub-regions NA1 are provided on both sides of the display area AA in the second direction X, respectively.

[0044] In these optional embodiments, the arrangement of the antenna modules 300 can be made more uniform, while the consistency of the wiring density in the display panel can be better improved, and the gaps between the touch wirings 210 and between the touch wirings 210 and the display area AA can be better utilized.

[0045] In some optional embodiments, referring to FIGS. 1 to 4 , there are multiple installation methods of the antenna module 300 in the display panel. Optionally, at least one antenna module 300 is arranged in the layer where the touch module 200 is located, i.e., at least a part of the antenna modules 300 are arranged in the same layer as the touch module 200, so that the antenna module 300 can be manufactured together when manufacturing the touch module 200, which can simplify the manufacturing of the antenna module 300 and improve the manufacturing efficiency of the display panel.

[0046] The electrode block 220 and the touch wiring 210 in the touch module 200 may be provided in the same layer or in different layers.

[0047] Optionally, the electrode block 220 is disposed in the same layer as the touch wiring 210, and at least one antenna module 300 is disposed in the same layer as the electrode block 220 and the touch wiring 210. The antenna module 300, the electrode block 220 and the touch wiring 210 can be simultaneously manufactured in the same process step, which can further improve the manufacturing efficiency of the display panel.

[0048] Optionally, the electrode block 220 and the touch wiring 210 are provided in different layers, and the at least one antenna module 300 is provided in the same layer as at least one of the electrode block 220 and the touch wiring 210. For example, the at least one antenna module 300 may be provided in the same layer as the electrode block 220. Alternatively, the at least one antenna module 300 may be provided in the same layer as the touch wiring 210. Alternatively, at least one of the multiple antenna modules 300 is provided in the same layer as the electrode block 220, and at least the other is provided in the same layer as the touch wiring 210.

[0049] In some alternative embodiments, still referring to FIG. 3 and FIG. 4, the display panel includes an array substrate layer 110 and a light-emitting layer disposed on a substrate 100, the light-emitting layer being located on the opposite side of the substrate 100 from the array substrate layer 110. The array substrate layer 110 includes a driving circuit, the light-emitting layer includes light-emitting units 120, and the driving circuit of the array substrate layer 110 drives the light-emitting units 120 of the light-emitting layer to emit light. The display panel further includes a sealing layer 130 for sealing the light-emitting units 120, the sealing layer 130 being disposed on the opposite side of the light-emitting layer from the array substrate layer 110. The sealing layer 130 provides protection for the light-emitting layer and can prevent water vapor or oxygen from entering the light-emitting units 120 and affecting the yield of the display panel. The sealing layer 130 may be a sealing film, a sealing glass, or the like. Or, the sealing layer 130 may include a sealing cover plate 131 and an annular sealing portion 132. The display panel further includes a touch module 200 disposed on a side of the encapsulation layer 130 opposite the light emitting layer, and a polarizer disposed on a side of the touch module 200 opposite the encapsulation layer 130 .

[0050] There are several installation forms of the antenna module 300 in the display panel. Optionally, at least one antenna module 300 may be provided in at least one film layer in the display panel, and / or the antenna module 300 may be provided between any two adjacent film layers in the display panel. That is, the antenna module 300 may be provided between the substrate 100 and the array substrate layer 110, and / or the antenna module 300 may be provided between the polarizer and the layer where the touch module 200 is located, and / or the antenna module 300 may be provided between the encapsulation layer 130 and the layer where the touch module 200 is located. When the encapsulation layer 130 is an encapsulation film and includes two or more alternating organic and inorganic layers, at least one antenna module may be provided between the substrate 100 and the array substrate layer 110. 300 may be located between adjacent organic and inorganic layers within the encapsulation layer 130.

The position of the annular sealing portion 132 is shown in FIG.

[0052] In these optional embodiments, the antenna module 300 is correspondingly positioned within the annular sealing portion 132, and when the annular sealing portion 132 and the glass cover plate are connected to each other using a high-temperature process such as sintering, the impact of high temperatures on the antenna module 300 can be reduced, and the impact of the antenna module 300 on the sintering energy can also be reduced.

[0053] In other embodiments, the antenna module 300 and the touch module 200 may be located on the opposite side of the encapsulation layer 130 from the substrate 100 .

[0054] Optionally, the display panel further includes a protective layer located on the opposite side of the touch module 200 and the antenna module 300 from the substrate 100, so that the protective layer can protect the antenna module and the touch module 200.

[0058] There are multiple ways in which the antenna modules 300 can be connected in series with each other, and as described above, still referring to FIG. 5, two antenna modules 300 that are connected in series with each other may be connected in series with each other by being connected to the same antenna wiring 500, i.e., the antenna wiring 500 may be multiplexed as a series connection line 30a.

[0059] Please refer to FIG. 6, which is a partially enlarged structural schematic diagram of FIG. 1 in another embodiment of the first aspect of the present invention.
