[0033] To better understand this application, the following will be combined with... Figures 1 to 14 The display panel and display device according to embodiments of this application will be described in detail.

[0034] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of this application; Figure 2 yes Figure 1 A partially enlarged structural diagram. Figure 3 yes Figure 2 A partial sectional view.

[0035] like Figures 1 to 3 As shown, an embodiment of the first aspect of this application provides a display panel, including: a support layer 100 comprising a conductive material; an antenna layer 200 disposed on one side of the support layer 100 in the thickness direction Z of the display panel, the antenna layer 200 including an antenna element 210; wherein the support layer 100 includes a through gap 101, and the projection of the antenna element 210 in the thickness direction Z and the projection of the gap 101 in the thickness direction Z at least partially overlap.

[0036] In the display panel provided in this application, the display panel includes a support layer 100 and an antenna layer 200. The support layer 100 supports other film layers of the display panel, and the antenna layer 200 enables wireless signal transmission of the display panel. The support layer 100 includes a conductive material. Coupling capacitance 420 may be generated between the support layer 100 and the antenna element 210 in the antenna layer 200, affecting the wireless signal transmission of the antenna element 210. In the embodiments of this application, a gap 101 is provided on the support layer 100, and the projection of the gap 101 along the thickness direction Z and the projection of the antenna element 210 along the thickness direction Z at least partially overlap. This reduces the overlap area between the conductive material on the support layer 100 and the antenna element 210, thereby reducing the coupling capacitance 420 and improving the antenna performance.

[0037] There are various ways to set up the support layer 100. For example, the support layer 100 can be a steel sheet structure. The material of the support layer 100 includes conductive materials such as steel, so that the support layer 100 has good rigidity and strength and can improve the support.

[0038] Optional, such as Figure 3 As shown, the display panel also includes a buffer layer 300, which can be disposed between the support layer 100 and the antenna layer 200 to increase the spacing between the support layer 100 and the antenna layer 200, further reducing the coupling capacitance 420 and improving antenna performance. Optionally, the material of the buffer layer 300 may include foam, giving the buffer layer 300 the advantages of being lightweight, low-cost, and having good buffering performance.

[0039] Optional, such as Figure 3As shown, the display panel also includes a driving circuit layer 400, which may be located between the buffer layer 300 and the antenna layer 200. Alternatively, the antenna layer 200 may be located within the driving circuit layer 400. Optionally, the driving circuit layer 400 includes a driving circuit for driving the light-emitting unit 630 of the display panel to emit light. For example, the driving circuit layer 400 includes a substrate 401 and a first conductive layer 402, a second conductive layer 403, and a third conductive layer 404 sequentially stacked on one side of the substrate 401. The driving circuit layer 400 also includes a transistor 410 and a capacitor 420. The transistor 410 includes an active portion 411, a gate 412, a source 413, and a drain 414. The capacitor 420 includes a first electrode 421 and a second electrode 422. The first electrode 421 and the gate 412 may be located on the first conductive layer 402, the second electrode 422 may be located on the second conductive layer 403, and the source 413 and the drain 414 may be located on the third conductive layer 404.

[0040] Antenna element 210 may be located within at least one of the first conductive layer 402, the second conductive layer 403, and the third conductive layer 404. Alternatively, antenna layer 200 may be located on the side of drive circuit layer 400 opposite to buffer layer 300.

[0041] Optional, such as Figure 3 As shown, a planarization layer 500 may also be provided on the side of the third conductive layer 404 opposite to the second conductive layer 403 to improve the flatness of the film.

[0042] Optional, such as Figure 3 As shown, the display panel may further include a pixel definition layer 600, which is located between the driving circuit layer 400 and the antenna layer 200. Optionally, the pixel definition layer 600 is located on the side of the planarization layer 500 opposite to the third conductive layer 404. The pixel definition layer 600 may include a pixel defining portion 610 and a pixel opening 620, the pixel opening 620 for accommodating the light-emitting unit 630, and the pixel defining portion 610 for improving the problem of light emission crosstalk between different light-emitting units 630.

[0043] Optionally, a first electrode 710 layer is disposed on the planarization layer 500. The first electrode 710 layer includes a plurality of spaced-apart first electrodes 710, located on the side of the light-emitting unit 630 facing the support layer 100. Optionally, a second electrode 720 layer can be disposed on the side of the pixel definition layer 600 and the light-emitting unit 630 away from the support layer 100. The second electrode 720 layer includes second electrodes 720, which can be surface electrodes. The second electrode 720 and the first electrode 710 jointly drive the light-emitting unit 630 to emit light. One of the first electrode 710 and the second electrode 720 is an anode, and the other is a cathode. In this embodiment, the first electrode 710 is used as the anode and the second electrode 720 is used as the cathode for illustration. The first electrode 710 is electrically connected to one of the source electrode 413 and the drain electrode 414.

[0044] Optionally, the display panel also includes an encapsulation layer 800, which is located between the pixel definition layer 600 and the antenna layer 200. For example, the encapsulation layer 800 is located on the side of the second electrode 720 layer facing away from the pixel definition layer 600, and the antenna layer 200 is located on the side of the encapsulation layer 800 facing away from the second electrode 720. The antenna layer 200 is located on the encapsulation layer 800 to mitigate the impact of the antenna layer 200 on the encapsulation effect.

[0045] Optionally, the display panel also includes a touch layer, and the antenna layer 200 and the touch layer can be reused. Alternatively, the antenna layer 200 and the touch layer can be stacked on top of each other. When the antenna layer 200 and the touch layer are stacked on top of each other, the antenna layer 200 can be located on the side of the touch layer facing or away from the encapsulation layer 800. Optionally, the touch layer includes touch electrodes for implementing the touch function of the display panel.

[0046] Optionally, when the touch layer and antenna layer 200 are reused, the touch electrodes and antenna elements 210 can be spaced apart and insulated from each other. Optionally, both the touch layer and antenna layer 200 are located within a grid-like conductive layer, which includes multiple intersecting traces. Part of the traces forms the antenna element 210, and another part of the traces forms the touch electrode.

[0047] There are various ways to configure the antenna element 210. For example, the antenna element 210 includes a radiating section 211 and a feeding section 212, which are electrically connected to each other. The feeding section 212 is used to transmit signals to the radiating section 211, and the radiating section 211 is used to receive or transmit wireless signals.

[0048] When the antenna element 210 includes a radiating portion 211 and a feeding portion 212, the projections of the radiating portion 211 and / or the feeding portion 212 in the thickness direction Z and the projection of the gap 101 in the thickness direction Z at least partially overlap. This reduces the parasitic capacitance 420 between the radiating portion 211 and / or the feeding portion 212 and the support layer 100, thereby improving antenna performance.

[0049] Optionally, the projection of the connection point between the radiating section 211 and the feed section 212 in the thickness direction Z at least partially overlaps with the projection of the gap 101 in the thickness direction Z. The current intensity at the connection point between the radiating section 211 and the feed section 212 may be relatively strong. This overlap with the gap 101 can better reduce the parasitic capacitance 420 and improve antenna performance.

[0050] There are various ways to set the support layer 100. In some optional embodiments, the support layer 100 includes a first region 110 and a second region 120 that are sequentially divided along the first direction Y. The support layer 100 includes a first portion 130 located in the first region 110. A gap 101 is formed on the side of the first portion 130 facing the second region 120. The projection of the feed portion 212 along the thickness direction Z and the projection of the first portion 130 along the thickness direction Z at least partially overlap.

[0051] In these optional embodiments, the support layer 100 includes a first region 110 and a second region 120. The first region 110 can be used to support the film structure in the region where the feed section 212 is located, and the second region 120 can be used to support the film structure in the region where the radiating section 211 is located. A gap 101 is formed on the side of the first portion 130 facing the second region 120, making it easy for the connection position of the feed section 212 and the radiating section 211 to overlap with the gap 101. The projection of the feed section 212 along the thickness direction Z and the projection of the first portion 130 along the thickness direction Z at least partially overlap, so that the support layer 100 can serve as a ground layer for the feed section 212, improving antenna performance.

[0052] Optionally, the second region 120 can be left empty, that is, the conductive material of the support layer 100 is disposed in the first region 110 to form the first portion 130, and the support layer 100 does not form a solid structure in the second region 120.

[0053] Alternatively, in some other optional embodiments, the projection of the radiating portion 211 along the thickness direction Z is located within the projection of the second region 120 along the thickness direction Z, and the support layer 100 further includes a second portion 140 located in the second region 120, the second portion 140 and the first portion 130 being spaced apart to form a gap 101.

[0054] In these optional embodiments, the gap 101 is formed by a first portion 130 and a second portion 140 spaced apart, which simplifies the arrangement of the gap 101 and allows the gap 101 to be positioned close to the connection point between the radiating portion 211 and the feed portion 212. The radiating portion 211 is located in the second region 120, and the second portion 140 within the second region 120 can provide support to the film layer in the region where the radiating portion 211 is located.

[0055] Optionally, there can be multiple antenna elements 210. When the second portion 140 and the first portion 130 are spaced apart to form a gap 101, the projections of the multiple antenna elements 210 in the thickness direction Z at least partially overlap with the projection of the gap 101 in the thickness direction Z. This simplifies the arrangement of the support layer 100.

[0056] Optionally, the radiating part 211 and the feeding part 212 are spaced apart along the first direction Y, and the multiple antenna elements 210 can be spaced apart along the second direction X, with the first direction Y, the second direction X and the thickness direction Z intersecting each other.

[0057] In some alternative embodiments, such as Figure 4 As shown, the first portion 130 has a first sidewall 131 facing the second portion 140. The first sidewall 131 is recessed in a direction away from the second portion 140 to form a first groove 132. A plurality of feed portions 212 are spaced apart along the second direction X. The first groove 132 is located between two adjacent feed portions 212.

[0058] In these optional embodiments, a first groove 132 is provided on the first portion 130. When a parasitic current is generated between the feed portion 212 and the first portion 130, since the first groove 132 is provided between two adjacent feed portions 212, the induced current needs to flow around the groove. This significantly increases the path of the induced current flow between the feed portion 212 and the first portion 130, thereby reducing the intensity of the corresponding induced current flow between two adjacent feed portions 212, improving the isolation between different antenna elements 210, and thus improving the radiation performance of the antenna element 210.

[0059] There are various ways to arrange the shape of the first groove 132. For example, the first part 130 includes at least two first wall parts 133. The ends of the two first wall parts 133 away from the second part 140 are connected to each other to form the first groove 132. That is, the projection shape of the first groove 132 along the thickness direction Z is triangular.

[0060] Or, such as Figure 4As shown, the first portion 130 includes two first wall portions 133 spaced apart, and a first bottom portion 134 connected between the first wall portions 133. The first bottom portion 134 and the first wall portions 133 enclose a first groove 132. That is, the projection shape of the first groove 132 along the thickness direction Z is rectangular.

[0061] Optionally, the first groove 132 is disposed through the first portion 130 to further reduce parasitic current and improve antenna performance.

[0062] In some alternative embodiments, such as Figure 6 and Figure 7 As shown, the second portion 140 has a second sidewall 141 facing the first portion 130. The second sidewall 141 is recessed in a direction away from the first portion 130 to form a second groove 142. The projection of the second groove 142 in the thickness direction Z and the projection of the radiating portion 211 in the thickness direction Z at least partially overlap.

[0063] In these alternative embodiments, a second groove 142 is formed on the second portion 140. The second groove 142 is formed by a recess in the second sidewall 141, such that a gap 101 can be formed between the second groove 142 and the first portion 130. The projection of the second groove 142 in the thickness direction Z at least partially overlaps with the projection of the radiating portion 211 in the thickness direction Z, which can reduce the parasitic capacitance 420 generated between the radiating portion 211 and the second portion 140 and improve antenna performance.

[0064] Optionally, the projection of the radiating part 211 in the thickness direction Z is located within the projection of the second groove 142 in the thickness direction Z, so as to further reduce the parasitic capacitance 420 between the radiating part 211 and the second part 140 and improve the antenna performance.

[0065] Optionally, the shape of the projection of the radiating part 211 along the thickness direction Z and the shape of the projection of the second groove 142 along the thickness direction Z can be adapted to each other, so that the projection of the radiating part 211 in the thickness direction Z is located within the projection of the second groove 142 in the thickness direction Z, thereby minimizing the distribution area of ​​the second groove 142, increasing the distribution area of ​​the second portion 140, and improving the support capacity of the support layer 100.

[0066] Optionally, the shape of the second groove 142 can be configured in various ways, for example, as shown in... Figure 7 As shown, the second portion 140 includes at least two second wall portions 143. The ends of the two second wall portions 143 away from the first portion 130 are connected to each other to form a second groove 142. That is, the projection of the second groove 142 along the thickness direction Z can be part of a triangle.

[0067] Or, such as Figure 6As shown, the second portion 140 includes two second wall portions 143 spaced apart and a second bottom portion 144 connected between the second wall portions 143. The second bottom portion 144 and the second wall portion 143 enclose each other to form a second groove 142, that is, the projection of the second groove 142 along the thickness direction Z can be a part of a rectangle.

[0068] Optionally, the second groove 142 is disposed through the second portion 140. This further reduces the parasitic capacitance 420 between the radiating portion 211 and the second portion 140, thereby improving antenna performance.

[0069] Optionally, as shown in 8, the first wall portion 133 is inclined relative to the first direction Y, which can increase the extension length of the wall portion and increase the flow distance of the induced current on the wall portion.

[0070] Optional, such as Figure 4 As shown, in a cross-section parallel to the first direction Y, the relative edges of the two first wall portions 133 are symmetrically arranged. This simplifies the structure of the first groove 132 and facilitates its fabrication. And / or, the relative edges of the two second wall portions 143 are symmetrically arranged. This simplifies the structure of the second groove 142 and facilitates its fabrication.

[0071] like Figure 9 As shown, the first wall portion 133 and / or the second wall portion 143 have an arcuate edge 150. Optionally, the arcuate edge 150 is provided to protrude toward the first groove 132 or the second groove 142. In these optional embodiments, the arcuate edge 150 on the first wall portion 133 and / or the second wall portion 143 can further increase the extension length of the first wall portion 133 and / or the second wall portion 143, thereby increasing the flow distance of the induced current on the wall portion.

[0072] Alternatively, in some other alternative embodiments, such as Figure 10 As shown, the edge of the first wall portion 133 facing the first groove 132 includes a plurality of first protrusions 160, each first protrusion 160 protruding in the direction toward the first groove 132. In these optional embodiments, the first wall portion 133 is provided with a plurality of first protrusions 160, and each arcuate edge 150 may be located on each first protrusion 160. By providing a plurality of first protrusions 160, the extension length of the first wall portion 133 can be further increased, the flow distance of the induced current on the first wall portion 133 can be increased, and the isolation between different antenna elements 210 can be improved.

[0073] In other embodiments, the edge of the second wall portion 143 facing the second groove 142 may also include a plurality of second protrusions.

[0074] In some alternative embodiments, the first wall portion 133 and / or the second wall portion 143 are spaced apart by an equal distance in the second direction X. This makes the shape of the first groove 132 or the second groove 142 and the shape of the wall portion more regular, which can reduce manufacturing costs.

[0075] In some alternative embodiments, such as Figure 9 As shown, the first wall portion 133 and / or the second wall portion 143 have an arcuate edge 150 and a straight edge 170, which are connected to each other. Optionally, when the first wall portion 133 includes the straight edge 170, the straight edge 170 is located on the side of the arcuate edge 150 facing the first bottom 134. When the second wall portion 143 includes the straight edge 170, the straight edge 170 is located on the side of the arcuate edge 150 away from the second bottom 144.

[0076] In some alternative embodiments, the first wall portion 133 and / or the second wall portion 143 may also exclude the straight edge 170, and the first wall portion 133 and / or the second wall portion 143 may be arc-shaped as a whole, which can further increase the extension length of the first wall portion 133 and / or the second wall portion 143 and increase the flow distance of the induced current on the first wall portion 133 and / or the second wall portion 143.

[0077] In some alternative embodiments, such as Figure 6 , Figure 9 and Figure 10 As shown, the first bottom 134 and / or the second bottom 144 are arranged with equal width in the second direction X. This simplifies the shape of the first bottom 134 and / or the second bottom 144.

[0078] In some other alternative embodiments, such as Figure 11 As shown, a protrusion 180 is provided on the first bottom 134. This increases the extension length of the first bottom 134, increases the flow path length of the induced current on the first bottom 134, and can better reduce the flow intensity of the induced current, thereby improving the performance of the antenna assembly 10.

[0079] Optional, such as Figure 12 As shown, the first bottom 134 has a first inner edge 135 facing the first groove 132 and a first outer edge 136 facing away from the first groove 132. The shape of the first outer edge 136 and the shape of the first inner edge 135 can be adapted to simplify the shape of the first bottom 134, facilitate the fabrication and molding of the first bottom 134, and reduce manufacturing costs. For example, when the first bottom 134 protrudes toward the second portion 140, both the first outer edge 136 and the first inner edge 135 protrude toward the second portion 140, and the first outer edge 136 and the first inner edge 135 can be equally spaced.

[0080] Or, such as Figure 11 As shown, in some alternative embodiments, the first bottom 134 is provided with a plurality of third protrusions arranged along the first direction X toward the radiation portion 211, and the third protrusions protrude in the direction toward the opening of the first groove 132. This can increase the extension length of the first inner edge 135 and increase the flow path length of the induced current on the first inner edge 135.

[0081] Optionally, the width of the first bottom 134 along the first direction Y can be set to a constant width or a variable width. Setting the first bottom 134 to a constant width can simplify the shape of the first bottom 134, while varying the width of the first bottom 134 can increase the length of the current flow path.

[0082] Optionally, the width of the first groove 132 may be at least partially different along the first direction Y; for example, the width of the first groove 132 may gradually decrease to increase the length of the current flow path. And / or, the width of the first groove 132 may be the same to simplify the shape of the first groove 132.

[0083] Referring to the above, when there are multiple antenna elements 210, the number of gaps 101 can be one. The projections of the multiple antenna elements 210 in the thickness direction Z all overlap at least partially with the projections of the gaps 101 in the thickness direction Z. This simplifies the structure of the support layer 100.

[0084] In some other alternative embodiments, such as Figure 13 and Figure 14 As shown, when there are multiple antenna elements 210, there are also multiple gaps 101. The projections of each antenna element 210 in the thickness direction Z and the projections of each gap 101 in the thickness direction Z at least partially overlap. The multiple gaps 101 are spaced apart, which can improve the structural strength of the support layer 100, so that the support layer 100 has good support performance.

[0085] Optionally, antenna element 210 can be a millimeter-wave antenna or a non-millimeter-wave antenna. The millimeter-wave antenna is used to transmit and receive millimeter-wave antenna signals, and the non-millimeter-wave antenna is used to transmit and receive non-millimeter-wave antenna signals. This embodiment of the application uses a millimeter-wave antenna element 210 as an example for illustration.
