DETAILED DESCRIPTION

[0010] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0011] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0012] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "an", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0013] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0014] An embodiment of the present invention provides a display panel, such as Figure 1 As shown, Figure 1 This is a schematic structural diagram of a display panel provided by an embodiment of the present invention. The display panel includes a display area AA and a non-display area NA. The non-display area NA surrounds the display area AA.

[0015] The display panel further includes a substrate 1 .

[0016] The display panel further includes touch electrodes 2 and touch lines 3. The touch electrodes 2 are at least located in the display area AA, and the touch lines 3 are electrically connected to the touch electrodes 2 and are located in the non-display area NA.

[0017] Regarding the film position of the touch electrode 2, in one configuration, as shown in FIG. Figure 2A and Figure 2B As shown, Figure 2A A schematic diagram of a film layer structure of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 2B This is a schematic diagram of another film layer structure of a display panel provided by an embodiment of the present invention. One side of substrate 1 includes a stacked array layer 01, a light-emitting device layer 02, and a touch layer 03. Array layer 01 includes pixel circuits (not shown), light-emitting device layer 02 includes light-emitting elements 04, and touch layer 03 includes touch electrodes 2.

[0018] Regarding the specific structure of the touch electrode 2, in one configuration, Figure 1 、 Figure 3 and Figure 4 , Figure 3 for Figure 1 A schematic diagram of an enlarged structure of area A in the middle, Figure 4 for Figure 1 Another enlarged structural diagram of the middle area A shows that the touch electrode 2 is a grid structure, the mesh of which exposes the light-emitting element 04 to avoid blocking the light emitted by the light-emitting element 04. The grid shape of the touch electrode 2 may be related to the shape and arrangement of the light-emitting element 04.

[0019] For more details, see Figure 1 The touch electrodes 2 include first touch electrodes 21 and second touch electrodes 22. Adjacent first touch electrodes 21 arranged along a first direction x are electrically connected via first connecting portions 71. Adjacent second touch electrodes 22 arranged along a second direction x are electrically connected via second connecting portions 72. The second connecting portions 72 are insulated from and intersect with the first connecting portions 71. The first direction x intersects the second direction y.

[0020] The first touch structure T1 is composed of a plurality of first touch electrodes 21 arranged along a first direction x and connected sequentially by first connecting portions 71. The second touch structure T2 is composed of a plurality of second touch electrodes 22 arranged along a second direction y and connected sequentially by second connecting portions 72. One of the first touch structure T1 and the second touch structure T2 is a touch sensing structure, and the other is a touch driving structure, which work together to implement the touch function.

[0021] Combine Figure 2A and Figure 2B The touch layer 03 includes a touch bridge layer TM1 and a touch metal layer TM2. The touch bridge layer TM1 is located on the side of the touch metal layer TM2 close to the substrate 1. The touch electrode 2 is located on the touch metal layer TM2. One of the first connecting portion 71 and the second connecting portion 72 is located on the touch bridge layer TM1, and the other is located on the touch metal layer TM2. Figure 2A and Figure 2B The illustration is made by taking an example where the first connection portion 71 is located in the touch bridge layer TM1 and the second connection portion 72 is located in the touch metal layer TM2 .

[0022] Accordingly, the touch wires 3 may specifically include a first touch wire 31 electrically connected to the first touch electrode 21 and a second touch wire 32 electrically connected to the second touch electrode 22 .

[0023] The display panel further includes a shielding structure 4 and a shielding trace 5 .

[0024] The shielding structure 4 is located between the substrate 1 and the touch electrodes 2, for example, between the touch metal layer TM2 and the array layer 01. The shielding structure 4 overlaps the touch electrodes 2 in a direction perpendicular to the plane of the substrate 1.

[0025] See also Figure 3 and Figure 4 The shielding structure 4 may also be a grid structure, with the mesh of the shielding structure 4 exposing the light-emitting element 04. In a direction perpendicular to the plane of the substrate 1, the grid lines of the shielding structure 4 overlap with the grid lines of the touch electrodes 2. The width of the grid lines in the shielding structure 4 may be the same as or different from the width of the grid lines in the touch electrodes 2. In an embodiment of the present invention, to achieve a better shielding effect, the width of the grid lines in the shielding structure 4 may be set to be greater than the width of the grid lines in the touch electrodes 2.

[0026] The shielding trace 5 includes a first shielding line 6 . The first shielding line 6 is located in the non-display area NA and at least partially surrounds the display area AA. The first shielding line 6 is electrically connected to the shielding structure 4 .

[0027] In an embodiment of the present invention, the touch electrode 2 can be used to detect touch operations of touch tools such as an active pen, and can also detect touch operations of user fingers. In one driving mode, the touch operations of the touch tool and the touch operations of the user's fingers are detected in a time-sharing manner.

[0028] In the technical solution provided by the embodiments of the present invention, a shielding structure 4 is provided below the touch electrode 2. Shielding structure 4 can be used to shield the display signal and display noise, thereby reducing interference from the display noise with the touch function signal. For example, shielding structure 4 can reduce interference from the display signal and display noise with the touch signal on the touch electrode 2. Alternatively, when a touch tool such as an active pen is used to control the display panel, the touch tool communicates with the touch electrode 2, and shielding structure 4 can also reduce interference from the display signal and display noise with the signal transmitted by the touch tool.

[0029] Furthermore, an embodiment of the present invention also provides a first shielding wire 6 for providing a shielding signal to the shielding structure 4. The first shielding wire 6 surrounds the display area AA, so that the shielding structure 4 can establish connections with the first shielding wire 6 at multiple positions. For example, in the four upper, lower, left and right frames, the shielding structure 4 is connected to the first shielding wire 6 to significantly improve the uniformity of the shielding signal in the display area AA, especially in medium and large-sized display panels, to achieve a better shielding effect and greatly improve the touch performance.

[0030] In one possible implementation, see again Figure 1 The first shielding line 6 is located on a side of the touch line 3 close to the display area AA.

[0031] The first shielding line 6 is spaced between the touch line 3 and the display area AA. On the one hand, the first shielding line 6 can be used to shield the signal or noise in the display area AA from interfering with the signal on the touch line 3. On the other hand, the first shielding line 6 is closer to the shielding structure 4, making it easier to establish a connection between the two.

[0032] In one possible embodiment, see Figure 5 and Figure 6 , the shielding structure 4 is connected to the first shielding line 6 through the first connecting line 7.

[0033] In one setup, such as Figure 5 and Figure 6 As shown, Figure 5 A schematic diagram of a connection between the shielding structure and the first shielding line provided by an embodiment of the present invention is provided. Figure 6 This is another schematic diagram of the connection between the shielding structure and the first shielding wire provided by an embodiment of the present invention. The number of first connecting wires 7 can be multiple, and there are gaps between adjacent first connecting wires 7. In this structure, multiple shielding signal access points are established between the shielding structure 4 and the first shielding wire 6, which can improve the uniformity of the shielding signal at different positions of the shielding structure 4. Figure 5 The first connecting line 7 can be provided in a different layer from the shielding structure 4 and at least one of the first shielding line 6, and the first connecting line 7 and the shielding structure 4 and / or the first shielding line 6 in a different layer are electrically connected through a via. Alternatively, see Figure 6 The first connecting line 7 can also be arranged on the same layer as the shielding structure 4 and at least one of the first shielding line 6. The first connecting line 7 is directly connected to the shielding structure 4 and / or the first shielding line 6 on the same layer to achieve electrical connection.

[0034] When the shielding structure 4 is electrically connected to the first shielding wire 6 through a plurality of first connecting wires 7, in order to further improve the uniformity of the shielding signal, refer again to Figure 5 and Figure 6 , multiple spaced shielding signal access points can be evenly spaced in the non-display area NA on one side of the display area AA. That is, among the multiple first connection lines 7 arranged in the same direction, the distances between adjacent first connection lines 7 are equal.

[0035] In one possible implementation, see again Figure 1 The touch electrodes 2 are connected to the touch lines 3 via second connection lines 8. The second connection lines 8 electrically connected to the first touch electrodes 21 extend along the first direction x, and the second connection lines 8 electrically connected to the second touch electrodes 22 extend along the second direction y.

[0036] It can be understood that the non-display area NA includes four frames: top, bottom, left and right.

[0037] See also Figure 7 and Figure 8 The non-display area NA includes a first non-display area NA1 and a second non-display area NA2 located on opposite sides of the display area AA in the first direction x. One of the first non-display area NA1 and the second non-display area NA2 is a left frame, and the other is a right frame.

[0038] The non-display area NA further includes a third non-display area NA3 and a fourth non-display area NA4 on opposite sides of the display area AA in the second direction y. In the embodiment of the present invention, the shielding trace 5 is connected to the first lead 16 in the third non-display area NA3, and the first lead 16 is also connected to the pin 17. This means that the third non-display area NA3 serves as a lower frame, and the fourth non-display area NA4 serves as an upper frame.

[0039] Regarding the connection method between the touch electrode 2 and the second connection line 8, in one connection method, as shown in FIG. Figure 7 As shown, Figure 7 This is another structural diagram of a display panel provided by an embodiment of the present invention, employing a "2T2R" touch structure. The first touch structure T1 is connected to the first touch line 31 via second connection lines 8 in the first non-display area NA1 and the second non-display area NA2, respectively. The second touch structure T2 is connected to the second touch line 32 via second connection lines 8 in the third non-display area NA3 and the fourth non-display area NA4, respectively.

[0040] Or, in another connection method, such as Figure 8 As shown, Figure 8 This is another structural diagram of a display panel provided by an embodiment of the present invention, employing a "1T1R" touch structure design. A portion of the first touch structure T1 is connected to the first touch line 31 via the second connection line 8 in the first non-display area NA1. The remaining portion of the first touch structure T1 is connected to the first touch line 31 via the second connection line 8 in the second non-display area NA2. The second touch structure T2 is connected to the second touch line 32 via the second connection line 8 in the third non-display area NA3.

[0041] In the embodiment of the present invention, the second connecting line 8 and the first connecting line 7 are provided in the same layer or in different layers.

[0042] The second connecting line 8 and the first connecting line 7 are both located in the non-display area NA. When the second connecting line 8 and the first connecting line 7 are on the same layer, the two connecting lines only occupy one metal layer. Short circuits can be avoided by avoiding each other, which can save film layers. When the second connecting line 8 and the first connecting line 7 are on different layers, the coupling between them is reduced, which can reduce the impact on the shielding signal when the touch signal jumps, thereby improving the stability of the shielding signal. Furthermore, when the second connecting line 8 and the first connecting line 7 are arranged on different layers, the second connecting line 8 and the first connecting line 7 do not overlap in a direction perpendicular to the plane of the substrate 1.

[0043] In one possible implementation, see again Figure 7 and Figure 8 , there are m first connecting lines 7 between adjacent second connecting lines 8, where m is an integer greater than or equal to 1.

[0044] For example, when the touch structure adopts the "2T2R" design, see Figure 7 The shielding structure 4 is connected to the first shielding line 6 through multiple first connecting lines 7 in the first non-display area NA1, the second non-display area NA2, the third non-display area NA3 and the fourth non-display area NA4, and in these four non-display areas, m first connecting lines 7 are included between adjacent second connecting lines 8.

[0045] When the touch structure adopts the "1T1R" design, see Figure 8 The shielding structure 4 is connected to the first shielding lines 6 via a plurality of first connection lines 7 in at least the first non-display area NA1, the second non-display area NA2, and the third non-display area NA3. Furthermore, in each of these three non-display areas, m first connection lines 7 are included between adjacent second connection lines 8. Furthermore, the shielding structure 4 may also be connected to the first shielding lines 6 via a plurality of first connection lines 7 in the fourth non-display area NA4. The number and spacing of the first connection lines 7 in the fourth non-display area NA4 may be consistent with the number and spacing of the first connection lines 7 in the third non-display area NA3.

[0046] When m first connection lines 7 are included between adjacent second connection lines 8, it means that the shielding signal access points and the touch signal access points are periodically distributed. The distribution design of the shielding signal access points is more regular, which helps to improve the uniformity of the shielding signal in the display area AA.

[0047] In a feasible embodiment, m≥2, that is, at least two first connecting lines 7 are arranged between adjacent second connecting lines 8. In this way, the number of first connecting lines 7 is large, the shielding structure 4 can be connected to the first shielding line 6 at more positions, and the uniformity of the shielding signal in the display area AA is better.

[0048] When m≥2, further, as Figure 9 As shown, Figure 9 This is another structural diagram of a display panel provided by an embodiment of the present invention. A first distance k1 is defined between a second connecting line 8 and an adjacent first connecting line 7. Among the m first connecting lines 7 between adjacent second connecting lines 8, a second distance k2 is defined between adjacent first connecting lines 7. The first distance k1 is greater than the second distance k2.

[0049] The first connection line 7 is used to transmit touch signals, and the second connection line 8 is used to transmit shielding signals. The two signals are different. Increasing the distance between the second connection line 8 and the first connection line 7 will help reduce the coupling between the two. Even if the two are on the same layer, there will be no significant coupling.

[0050] In the embodiment of the present invention, the first shielding line 6 may adopt a double-layer wiring design so that the first shielding line 6 has a smaller load, thereby reducing the attenuation and delay of the shielding signal during transmission.

[0051] When the first shielding line 6 is a double-layer wiring, in a feasible embodiment, as Figure 10 and Figure 11 As shown, Figure 10 A schematic diagram of a partial structure of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 11 This is another partial structural schematic diagram of the display panel provided in an embodiment of the present invention. The first shielding line 6 includes a first sub-shielding line 9 and a second sub-shielding line 10 that are arranged in different layers and are electrically connected. In a direction perpendicular to the plane where the substrate 1 is located, the first sub-shielding line 9 and the second sub-shielding line 10 overlap.

[0052] The second connecting line 8 and the first sub-shielding line 9 are located on the first metal layer m1, and the second sub-shielding line 10 is located on the second metal layer m2. Furthermore, the first sub-shielding line 9 includes a plurality of spaced first line segments 11, each of which is electrically connected to the second sub-shielding line 10. Second connecting lines 8 are located between adjacent first line segments 11.

[0053] As previously described, the first shielding line 6 located between the touch line 3 and the display area AA can shield the display signal and display noise from interfering with the touch line 3 signal. When the first shielding line 6 is located inside the touch line 3, the second connecting line 8 will overlap with the first shielding line 6. To this end, when the second connecting line 8 and the first sub-shielding line 9 are arranged on the same layer, the first sub-shielding line 9 can be designed to include multiple spaced first line segments 11, allowing the second connecting line 8 to extend from the spaces between adjacent first line segments 11 to connect with the outer touch line 3, thereby ensuring that the first sub-shielding line 9 avoids the second connecting line 8.

[0054] Further, see Figure 11 , the first connecting line 7 can be located in the first metal layer m1, and the first connecting line 7 is directly connected to the first line segment 11. Alternatively, see Figure 10 The first connection line 7 can also be located in the second metal layer m2, and the first connection line 7 is directly connected to the second sub-shielding line 10. When the first connection line 7 is located in the second metal layer m2, the first connection line 7 and the second connection line 8 are arranged in different layers, and the coupling between the two is smaller.

[0055] In one configuration, combining FIG2 and Figure 10The first metal layer m1 can be the touch bridge layer TM1, and the second metal layer m2 can be the touch metal layer TM2. That is, the second sub-shielding line 10 is on the same layer as the touch electrode 2, and the first sub-shielding line 9 is on the same layer as the bridge in the touch structure, thereby achieving rational utilization of the metal layers.

[0056] In one possible implementation, Figure 12 As shown, Figure 12 This is another partial structural diagram of a display panel provided by an embodiment of the present invention. The first connecting line 7 and the shielding structure 4 are located in the first metal layer m1 , and the shielding structure 4 , the first connecting line 7 and the first line segment 11 are connected to each other.

[0057] Along the arrangement direction of the multiple first line segments 11, the length of the first connecting line 7 is equal to the length of the first line segment 11. Specifically, in the first non-display area NA1 and the second non-display area NA2, the length of the first connecting line 7 is equal to the length of the first line segment 11 in the second direction y; in the third non-display area NA3 and the fourth non-display area NA4, the length of the first connecting line 7 is equal to the length of the first line segment 11 in the first direction x. This maximizes the connection area between the first connecting line 7 and the shielding structure 4 while ensuring that the first connecting line 7 avoids the second connecting line 8, thereby optimizing the transmission of the shielding signal.

[0058] Furthermore, in a direction perpendicular to the plane of the display panel, at least a portion of the first connecting line 7 does not overlap with either the touch electrode 2 or the second sub-shielding line 10. When the length of the first connecting line 7 and the first line segment 11 are on the same layer and are equal in length, the connected first connecting line 7 and first line segment 11 form a planar metal. Within this planar metal, at least the portion that overlaps with the second sub-shielding line 10 can be classified as the first line segment 11, and the remaining portion can be classified as the first connecting line 7. In other words, at least a portion of the first connecting line 7 does not overlap with either the touch electrode 2 or the second sub-shielding line 10.

[0059] In the embodiment of the present invention, the touch line 3 may also adopt a double-layer wiring design so that the touch line 3 has a smaller load, thereby reducing the attenuation and delay of the touch signal during the transmission process.

[0060] In one possible implementation, see again Figure 10 and Figure 11 The touch line 3 includes a first sub-touch line 12 and a second sub-touch line 13 that are electrically connected to each other and are located in different layers. The first sub-touch line 12 and the second sub-touch line 13 overlap in a direction perpendicular to the plane of the substrate 1. The first sub-touch line 12 is located in the first metal layer m1, and the second sub-touch line 13 is located in the second metal layer m2.

[0061] That is, the double-layer wiring of the touch line 3 and the double-layer wiring of the shielding line are located in the same two metal layers. In this case, the two types of double-layer wiring occupy a relatively small number of film layers.

[0062] In one possible embodiment, see Figure 10 and Figure 13 The first connecting line 7 and the second connecting line 8 are on different layers to reduce coupling between them and improve the stability of the shielding signal. Furthermore, the first connecting line 7 and the first shielding line 6 are at least partially on the same layer, and the second connecting line 8 and the touch line 3 are at least partially on the same layer, reducing the number of film layers required for these traces and optimizing the film layer design.

[0063] It should be noted that “the first connecting wire 7 and the first shielding wire 6 are at least partially in the same layer” includes at least the following three situations: 1. Figure 13 , the first connecting line 7 and the first shielding line 6 are both single-layer routing and the two are on the same layer; 2. See Figure 10 , the first shielding line 6 is a double-layer wiring, and the first connecting line 7 is on the same layer as one layer of the double-layer wiring; third, the first connecting line 7 and the first shielding line 6 are both double-layer wiring and the two layers of wiring are on the same layer.

[0064] Similarly, “the second connecting line 8 and the touch line 3 are at least partially in the same layer” includes at least the following three situations: 1. See Figure 13 , the second connecting line 8 and the touch line 3 are both single-layer routing and the two are on the same layer; 2. See Figure 10 , the touch line 3 is a double-layer wiring, and the second connecting line 8 is on the same layer as one layer of the double-layer wiring; third, the second connecting line 8 and the touch line 3 are both double-layer wiring and the two layers of wiring are on the same layer.

[0065] In one possible implementation, see again Figure 10 The first shielding wire 6 and the touch wire 3 can both adopt a double-layer wiring design, and the double-layer wiring is electrically connected through vias 14. This double-layer structure can provide a smaller load on both the first shielding wire 6 and the touch wire 3, reducing the voltage drop and delay of the shielding signal and the touch signal during transmission.

[0066] Furthermore, the first connection line 7 and the second connection line 8 can be single-layer wiring, the first connection line 7 and one of the double-layer wirings of the first shielding line 6 are on the same layer, and the second connection line 8 and one of the double-layer wirings of the touch line 3 are on the same layer. Figure 10 The first connecting line 7 and the second sub-shielding line 10 are on the same layer, and the second connecting line 8 and the first sub-touch line 12 are on the same layer.

[0067] In one possible implementation, Figure 13 As shown, Figure 13This is another partial structural diagram of the display panel provided by an embodiment of the present invention. In the non-display area NA on one side of the display area AA, the length of the first connection line 7 along the direction intersecting with the arrangement direction of the second connection lines 8 is greater than the distance between two adjacent second connection lines 8.

[0068] For example, when the touch structure adopts the "2T2R" design, in the first non-display area NA1 and the second non-display area NA2, along the second direction y, the length of the first connecting line 7 is greater than the distance between the two adjacent second connecting lines 8, and in the third non-display area NA3 and the fourth non-display area NA4, along the first direction x, the length of the first connecting line 7 is greater than the distance between the two adjacent second connecting lines 8.

[0069] In this structure, the first connection lines 7 are longer in the direction extending from the non-display area. In one configuration, at least two first connection lines 7 are provided in each of the first non-display area NA1, the second non-display area NA2, the third non-display area NA3, and the fourth non-display area NA4, with spaces between adjacent first connection lines 7. Alternatively, in another configuration, one first connection line 7 is provided in each of the first non-display area NA1, the second non-display area NA2, the third non-display area NA3, and the fourth non-display area NA4, and these four first connection lines 7 are connected end to end in sequence to form a continuous line.

[0070] This structure allows for a larger connection area between the shielding metal 4 and the first shielding line 6, resulting in better shielding signal uniformity. Furthermore, in this structure, the shielding structure 4, first connecting line 7, and first shielding line 6 can be arranged on the same layer and connected, for example, all three being located in the touch bridge layer TM1 or in the anode layer of the light-emitting device layer 02. Furthermore, the touch electrode 2, second connecting line 8, and touch line 3 can be arranged on the same layer and connected, for example, all three being located in the touch metal layer TM2, to simplify wiring.

[0071] In one possible embodiment, combining Figure 13 and Figure 14 , Figure 14 for Figure 13 In a cross-sectional view taken along the A1-A2 direction, at least a portion of the first connecting line 7 is located on the side of the first connecting line 7 away from the substrate 1. In a direction perpendicular to the plane of the substrate 1, the first connecting line 7 overlaps with the touch line 3, thereby shielding the display signal and display noise below from affecting the touch signal on the touch line 3.

[0072] Further, combined with Figure 1The touch electrodes 2 include first touch electrodes 21 and second touch electrodes 22. Adjacent first touch electrodes 21 arranged along a first direction x are electrically connected via first connecting portions 71. Adjacent second touch electrodes 22 arranged along a second direction x are electrically connected via second connecting portions 72. The second connecting portions 72 are insulated from and intersect with the first connecting portions 71. The first direction x intersects the second direction y.

[0073] The touch wire 3 and the touch electrode 2 are in the same layer. The second connection wire 8 is also in the same layer as the touch electrode 2. The three are directly connected to each other without drilling, which increases the connection reliability.

[0074] In one possible implementation, Figure 15 As shown, Figure 15 This is another partial structural diagram of the display panel provided in an embodiment of the present invention. The first connecting line 7 can also be patterned. Some hollows 15 are provided on the first connecting line 7. To better ensure the shielding effect of the first connecting line 7 on the touch line 3, the hollows 15 may not overlap with the touch line 3 in a direction perpendicular to the plane of the substrate 1.

[0075] In one possible implementation, Figure 16 As shown, Figure 16 Another structural schematic diagram of a display panel provided in an embodiment of the present invention, the non-display area NA includes a first non-display area NA1 and a second non-display area NA2 located on opposite sides of the display area AA in the first direction x, and a third non-display area NA3 and a fourth non-display area NA4 located on opposite sides of the display area AA in the second direction y, and the first direction x intersects with the second direction y.

[0076] The touch electrodes 2 include first touch electrodes 21 and second touch electrodes 22. Adjacent first touch electrodes 21 arranged along a first direction x are electrically connected via first connecting portions 71. Adjacent second touch electrodes 22 arranged along a second direction x are electrically connected via second connecting portions 72, which are insulated from each other and cross-connected with the first connecting portions 71.

[0077] The first touch electrodes 21 are electrically connected to the touch lines 3 in the first non-display area NA1 through the second connection lines 8 , and the second touch electrodes 22 are electrically connected to the touch lines 3 in the third non-display area NA3 through the second connection lines 8 .

[0078] The first shielding line 6 is located on a side of the touch line 3 close to the display area AA. The touch line 3 and the first shielding line 6 are in the same layer, and the second connection line 8 and the first shielding line 6 are in different layers.

[0079] In which, along the first direction x, the total width of the first shielding line 6 and the first connecting line 7 in the first non-display area NA1 is smaller than the total width of the first shielding line 6 and the first connecting line 7 in the third non-display area NA3; and / or, along the second direction y, the total width of the first shielding line 6 and the first connecting line 7 in the third non-display area NA3 is smaller than the total width of the first shielding line 6 and the first connecting line 7 in the fourth non-display area NA4.

[0080] Taking the first non-display area NA1 and the second non-display area NA2 as an example, the first touch line 31 connected to the first touch electrode 21 is located in the first non-display area NA1. Since the first touch line 31 is on the same layer as the first shielding line 6 and the first connecting line 7, the width of the first connecting line 7 in the first non-display area NA1 and the second non-display area NA2 can be designed differently, that is, the total width of the first shielding line 6 and the first connecting line 7 can be designed differently. By setting the total width of the first shielding line 6 and the first connecting line 7 in the first non-display area NA1 to be smaller, some space can be freed up to accommodate the first touch line 31.

[0081] In one possible implementation, Figure 17 As shown, Figure 17 This is another schematic diagram of the structure of a display panel provided by an embodiment of the present invention. The non-display area NA includes a third non-display area NA3 and a fourth non-display area NA4 on opposite sides of the display area AA in the second direction y. Shielding trace 5 is connected to first lead 16 in the third non-display area NA3, and first lead 16 is also connected to pin 17. This means that the third non-display area NA3 serves as the lower frame, and the fourth non-display area NA4 serves as the upper frame.

[0082] The first shielding line 6 has a first break 18 in the fourth non-display area NA4 .

[0083] At this time, the first shielding line 6 is a non-closed structure, and the first shielding line 6 is disconnected at the upper frame. The disconnection position can refer to the main transmission point position of the whole machine antenna, thereby preventing the formation of a closed loop to interfere with the whole machine radio frequency.

[0084] In one possible implementation, Figure 18 As shown, Figure 18 This is another structural schematic diagram of a display panel provided in an embodiment of the present invention. The shielding trace 5 also includes a second shielding line 19. The second shielding line 19 is located in the non-display area NA and at least partially surrounds the display area AA. The second shielding line 19 is electrically connected to the first shielding line 6.

[0085] The shielding line 5 in this structure includes at least two shielding lines, namely a first shielding line 6 and a second shielding line 19 . This can reduce the overall impedance of the shielding line 5 and optimize the transmission of the shielding signal.

[0086] In one possible implementation, see again Figure 18 The non-display area NA also includes a third non-display area NA3 and a fourth non-display area NA4 on opposite sides of the display area AA in the second direction y. Shielding trace 5 is connected to first lead 16 in the third non-display area NA3, and first lead 16 is also connected to pin 17. This means that the third non-display area NA3 serves as the lower frame, and the fourth non-display area NA4 serves as the upper frame.

[0087] The second shielding line 19 is connected to the first shielding line 6 at least in the fourth non-display area NA4 .

[0088] Compared with the lower frame, the upper frame has less wiring. The second shielding line 19 is selected to be connected to the first shielding line 6 at least in the upper frame, which can facilitate the connection and wiring between the two.

[0089] Furthermore, the second shielding line 19 may also be provided with a second break 20 in the fourth non-display area NA4 , and both ends of the second shielding line 19 at the second break 20 are respectively connected to both ends of the first shielding line 6 at the first break 18 .

[0090] In one possible implementation, see again Figure 18 The first shielding line 6 is located on the side of the touch line 3 close to the display area AA, and the second shielding line 19 is located on the side of the touch line 3 away from the display area AA. For example, a grounding line for electrostatic protection is usually provided at the edge of the display panel, and the second shielding line 19 can be located between the touch line 3 and the grounding line.

[0091] The light-emitting device layer includes a cathode. When routing the touch lines 3 on the display panel, it is desirable to position them above the cathodes, as much as possible, to leverage the shielding effect provided by the cathodes. This means that the touch lines 3 should not be routed too far from the display area AA. Therefore, when the first shielding lines 6 are positioned between the touch lines 3 and the display area AA, the width of the first shielding lines 6 may be limited.

[0092] To this end, in an embodiment of the present invention, second shielding lines 19 are disposed around the periphery of touch lines 3. This allows the width of second shielding lines 19 to be unrestricted by the wiring position of touch lines 3. Second shielding lines 19 can have a larger width, reducing the overall load on shielding traces 5. In an embodiment of the present invention, at least some segments of second shielding lines 19 have a greater width than the width of first shielding lines 6.

[0093] Further, combined with Figure 18 and Figure 19 , Figure 19 This is another partial structural diagram of a display panel provided by an embodiment of the present invention. The second shielding line 19 includes a plurality of shielding line segments 40 connected in sequence.

[0094] The shielding line segment 40 includes a first shielding line segment 41 and a second shielding line segment 42. The second shielding line segment 42 is located on a side of the first shielding line segment 41 away from the third non-display area NA3. The width of the second shielding line segment 42 in the first direction x is greater than the width of the first shielding line segment 41 in the first direction x.

[0095] In the left and right frames, the further away from the bottom frame, the fewer touch lines 3 are arranged along the first direction x. Accordingly, the further away from the bottom frame, the more space there is for routing the second shielding line 19. To this end, the width of the second shielding line 19 can be designed differently at different locations, making the second shielding line segment 42 farther away from the bottom frame wider. This wider second shielding line segment 42 can then reduce the overall load on the shielding trace 5.

[0096] Further, see Figure 19 At least part of the touch lines 3 includes a plurality of touch line segments 43 , and the distance between the touch line segments 43 and the touch electrodes 2 decreases in a direction away from the third non-display area NA3 .

[0097] Along the direction away from the third non-display area NA3 , the widths of the plurality of shielding line segments 40 in the second direction y gradually increase.

[0098] As previously mentioned, the number of touch lines 3 decreases as the distance from the bottom frame decreases. In the above structure, the touch lines 3 in the left and right frames are designed as zigzag lines. Within a single touch line 3, the distance between the touch line 3 and the display area AA decreases as it moves from the bottom frame toward the top frame. This frees up space outside the touch line 3 for routing the second shielding line 19. Furthermore, within this space, the width of the shielding line segments 40 in the second shielding line 19 increases, optimizing the load design of the second shielding line 19.

[0099] In one possible implementation, Figure 20 As shown, Figure 20 This is another structural diagram of a display panel provided by an embodiment of the present invention. The touch electrodes 2 include drive electrodes 44 and sensing electrodes 45. Correspondingly, the touch lines 3 include drive lines 46 electrically connected to the drive electrodes 44 and sensing lines 47 electrically connected to the sensing electrodes 45.

[0100] In the embodiment of the present invention, one of the first touch electrode 21 and the second touch electrode 22 is a driving electrode 44, and the other is a sensing electrode 45. Figure 20 In the embodiment, the first touch electrodes 21 are driving electrodes 44 and the second touch electrodes 22 are sensing electrodes 45. Accordingly, the first touch lines 31 are driving lines 46 and the second touch lines 32 are sensing lines 47.

[0101] The non-display area NA further includes first protection lines 48 , and at least one first protection line 48 is adjacent to the sensing line 47 .

[0102] During touch detection, drive lines 46 provide touch signals to drive electrodes 44, forming an electric field around them. Due to the presence of capacitance, this electric field generates induced charges on the opposing sensing electrodes 45. When a finger or touching tool approaches the screen, the electric field distribution at the touch location changes, causing the amount of induced charge on sensing electrodes 45 at that location to change. This in turn transmits a touch signal via sensing lines 47 to the driver chip, allowing the driver chip to determine the touch location.

[0103] By setting a first protective line 48 at a position adjacent to at least part of the sensing line 47, the first protective line 48 can act as a shielding line to reduce electromagnetic interference, reduce signal crosstalk, etc., and ensure that the signal transmitted on the sensing line 47 is accurately and stably transmitted to the driver chip, avoiding problems such as misjudgment.

[0104] Further, see again Figure 20 At least one first shield line 48 is located between the sensing line 47 and the driving line 46. This first shield line 48 not only reduces signal crosstalk between the sensing line 47 and the driving line 46, but also absorbs some high-frequency noise signals, preventing such interference with the signals on the sensing line 47 and the driving line 46, thereby improving signal quality. Furthermore, this first shield line 48 balances the electromagnetic field distribution around the sensing line 47 and the driving line 46 to a certain extent, reducing distortion and reflection during signal transmission, ensuring signal integrity, and enhancing the touch cable 3's resistance to noise.

[0105] In one possible implementation, see again Figure 20 The non-display area NA further includes a second protective line 49 , which is located on a side of the touch line 3 away from the display area AA. The second protective line 49 can play an electrostatic protection role to prevent static electricity accumulation from affecting the touch line 3 .

[0106] The first protection line 48 and the second protection line 49 may both receive a ground signal.

[0107] In one possible embodiment, combining Figure 1 The touch electrodes 2 include first touch electrodes 21 and second touch electrodes 22. Adjacent first touch electrodes 21 arranged along the first direction x are electrically connected via first connecting portions 71. Adjacent second touch electrodes 22 arranged along the second direction x are electrically connected via second connecting portions 72, which are insulated from each other and cross-connected with the first connecting portions 71.

[0108] One of the first connecting portion 71 and the second connecting portion 72 is located at the same layer as the touch electrode 2 , and the other is located at the same layer as the shielding structure 4 .

[0109] In the above structure, shielding structure 4 utilizes the touch bridge layer TM1 for wiring. Because the touch bridge layer TM1 is generally used only for bridges, and the bridges occupy relatively little space, placing shielding structure 4 within the touch bridge layer TM1 effectively utilizes the space within the touch bridge layer TM1. Furthermore, the shielding structure 4 is located closer to the touch electrodes 2 in the touch bridge layer TM1, providing enhanced shielding effectiveness.

[0110] Or, in another possible embodiment, as Figure 22 and Figure 23 As shown, Figure 22 This is a schematic diagram of another film layer structure of a display panel provided by an embodiment of the present invention. Figure 23 This is a schematic diagram of the shielding structure, anode, and touch electrode provided in an embodiment of the present invention. The display panel further includes a light-emitting device layer 02, which is located between the substrate 1 and the touch electrode 2. The light-emitting device layer 02 includes an anode 50, a light-emitting layer 51, and a cathode layer 52.

[0111] The shielding structure 4 may also be in the same layer as the anode 50. Figure 23 The shielding structure 4 can be rounded and chamfered at the corners to form arc-shaped edges to prevent static electricity from damaging the anode 50.

[0112] The anode position corresponds to the position of the light-emitting element 04. The shielding structure 4 is placed on the same layer as the anode 50. This avoidance of the anode 50 means that the shielding structure 4 can present a grid structure that exposes the light-emitting element. Furthermore, when the shielding structure 4 is placed on the same layer as the anode 50, the shielding structure 4 is closer to the touch electrode 2, resulting in a better shielding effect.

[0113] In addition, in an embodiment of the present invention, the cathode layer 52 can also be patterned, and the cathode layer 52 includes two spaced parts, one part acts as a cathode for providing the cathode voltage required by the light-emitting element, and the other part acts as a shielding metal, and its position can correspond to the position of the shielding structure.

[0114] In one possible implementation, Figure 24 As shown, Figure 24 This is another structural diagram of a display panel provided by an embodiment of the present invention. The non-display area NA further includes a cathode bus 53 , and the cathode layer 52 is connected to the cathode bus 53 via a bonding metal 54 .

[0115] The first shielding line 6 is in the same layer as the bonding metal 54 and the anode 50 . The first shielding line 6 is located on a side of the bonding metal 54 close to the display area AA.

[0116] When the first shielding wire 6 and the overlapping metal 54 are on the same layer, the first shielding wire 6 is located on the inner side of the overlapping metal 54, which is convenient for connection with the shielding structure 4. For example, the first shielding wire 6 and the shielding structure 4 can be directly connected through the first connecting wire 7 of the same layer, and the first connecting wire 7 will not have a position conflict with the overlapping metal.

[0117] Furthermore, if Figure 25 As shown, Figure 25 This is another structural schematic diagram of the display panel provided in an embodiment of the present invention. The shielding trace 5 also includes a second shielding line 19. The second shielding line 19 is located on the side of the overlapping metal 54 away from the display area AA. The second shielding line 19 is electrically connected to the first shielding line 6 through the third connecting line 55.

[0118] The third connection line 55 is in the same layer as the anode 50 , and the strap metal 54 includes a plurality of spaced sub-strap metals 56 , with the third connection line 55 being located between adjacent sub-strap metals 56 .

[0119] The third connecting wire 55 is co-layered with the anode 50, saving film layers. Furthermore, the bonding metal 54 is divided into a plurality of spaced sub-bonding metals 56, allowing the third connecting wire 55 to extend between adjacent sub-bonding metals 56. This allows the bonding metal 54 and the third connecting wire 55 to avoid each other, thereby achieving reasonable routing between the bonding metal 54 and the third connecting wire 55.

[0120] Furthermore, when the second shielding line 19 is located on the side of the bonding metal 54 away from the display area AA, the second shielding line 19 can be provided in the same layer as the touch electrode 2 , that is, located in the touch metal layer TM2 .

[0121] In one possible implementation, Figure 26 As shown, Figure 26 This is another structural diagram of a display panel provided by an embodiment of the present invention. The non-display area NA further includes a cathode bus 53 , and the cathode layer 52 is connected to the cathode bus 53 via a bonding metal 54 .

[0122] The first shielding line 6 is located on the side of the lapping metal 54 away from the display area AA. The first shielding line 6 is connected to the shielding structure 4 through multiple first connecting lines 7. The first connecting line 7 is on the same layer as the lapping metal 54 and the anode 50. The lapping metal 54 includes multiple spaced sub-lapping metals 56, and the first connecting line 7 is included between adjacent sub-lapping metals 56.

[0123] The first connecting wire 7 is co-layered with the anode 50, saving film layers. Furthermore, the bonding metal 54 is divided into a plurality of spaced sub-bonding metals 56, allowing the first connecting wire 7 to extend between adjacent sub-bonding metals 56. This allows the bonding metal 54 and the first connecting wire 7 to avoid each other, thereby achieving reasonable routing between the bonding metal 54 and the first connecting wire 7.

[0124] Furthermore, when the first shielding line 6 is located on the side of the bonding metal 54 away from the display area AA, the first shielding line 6 can be provided in the same layer as the touch electrode 2 , that is, located in the touch metal layer TM2 .

[0125] In one possible implementation, Figure 27 and Figure 28 As shown, Figure 27 This is another partial structural diagram of a display panel provided by an embodiment of the present invention. Figure 28 This is another schematic diagram of a film layer structure of a display panel provided by an embodiment of the present invention. The display panel further includes an encapsulation film layer 57 . The encapsulation film layer 57 includes an inorganic encapsulation layer 58 and an organic encapsulation layer 59 . The organic encapsulation layer 59 includes a first edge 63 .

[0126] At least a portion of the first shielding line 6 is located on a side of the first edge 63 away from the display area AA.

[0127] The first shielding line 6 includes a first sub-shielding line 9 and a second sub-shielding line 10, which are electrically connected to each other and are located on different layers. A connecting via 60 is provided between the first sub-shielding line 9 and the second sub-shielding line 10. The connecting via 60 is also located on the side of the first edge 63 away from the display area AA. Furthermore, the first sub-shielding line 9 can be located on the same layer as the anode 50, thereby directly connecting to the shielding structure 4 and the first connecting line 7. The second sub-shielding line 10 can be located on the same layer as the touch electrode 2.

[0128] When at least part of the first shielding line 6 and the connecting via 60 in its double-layer wiring are located outside the first edge 63 of the organic encapsulation layer 59, it means that the first shielding line 6 and the connecting via 60 will be further outward, thereby avoiding affecting the wiring of other original lines in the non-display area NA.

[0129] Compared to the organic encapsulation layer 59, the edge of the inorganic encapsulation layer 58 is further outward, that is, closer to the edge of the display panel. Furthermore, in an embodiment of the present invention, at least a portion of the first shielding line 6 and the connecting vias 60 in the double-layer wiring thereof may be located on a side of the edge of the inorganic encapsulation layer 58 away from the display area AA.

[0130] In order to provide driving signals to the pixel circuits in the display area AA, a shift register is usually provided in the non-display area NA. Figure 29 As shown, Figure 29This is another structural schematic diagram of a display panel provided in an embodiment of the present invention. The non-display area NA also includes a first shift register 61. The first shift register 61 includes a plurality of cascaded first shift units 62. When the shielding metal 4 is connected to the first shielding line 6 through the first connecting line 7 and the first connecting line 7 is in the same layer as the anode, the first connecting line 7 is close to the array layer. In order to reduce the coupling between the first connecting line 7 and the metal wiring in the first shift unit 62, the first connecting line 7 can be located between adjacent first shift units 62. That is, after the shielding structure 4 leads out the first connecting line 7, the first connecting line 7 extends from the gap between the adjacent first shift units 62 to connect with the first shielding line 6.

[0131] In a feasible implementation, the shielding trace 5 may receive a fixed voltage, such as a ground signal, so that the shielding structure 4 can achieve a shielding function.

[0132] Based on the same inventive concept, an embodiment of the present invention further provides a display device, such as Figure 30 As shown, Figure 30 1 is a schematic structural diagram of a display device provided by an embodiment of the present invention, the display device includes the above-mentioned display panel 100. Of course, Figure 30 The display device shown is for illustrative purposes only. The display device may be any electronic device with a display function, such as a mobile phone, a tablet computer, a laptop computer, an e-reader, or a television.

[0133] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
