[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] See also Figure 1 and Figure 2 , Figure 1 This is a schematic structural diagram of an embodiment of a touch display panel of the present application. Figure 2 for Figure 1 The touch display panel includes a touch layer 10 and an array layer 12 which are stacked.

[0016] Specifically, Figure 1 As shown, the touch layer 10 includes a plurality of first channels 100 arranged side by side, and in the extension direction of the first channels 100 , two opposite ends of the first channels 100 are respectively connected to a first touch lead 102 .

[0017] Alternatively, if Figure 1 As shown, a plurality of first channels 100 may be arranged side by side along a first direction X, the extension direction of each first channel 100 is parallel to the second direction Y, and the first direction X intersects the second direction Y. Preferably, the first direction X is perpendicular to the second direction Y.

[0018] Alternatively, if Figure 1 As shown, in the second direction Y, each first channel 100 includes a plurality of first electrodes 1000 connected in sequence, and the first electrodes 1000 may be in a block shape, etc. The above “in the extension direction of the first channel 100, the two opposite ends of the first channel 100 are respectively connected to a first touch lead 102” can be understood as: the two first electrodes 1000 at the outermost sides of the first channel 100 in the second direction Y are respectively independently connected to a first touch lead 102; that is, at this time, one first channel 100 is electrically connected to two first touch leads 102. For example, Figure 1 The first touch lead connected to the first electrode 1000 at the uppermost end of the first channel 100 is labeled 102a. Figure 1 The first touch lead connected to the first electrode 1000 at the lower end of the first channel 100 is labeled 102 b to distinguish the two first touch leads 102 .

[0019] Alternatively, if Figure 1 As shown, the touch layer 10 may further include a plurality of second channels 104 arranged side by side along the second direction Y, and the extension direction of each second channel 104 is parallel to the first direction X; and in the first direction X, each second channel 104 includes a plurality of second electrodes 1040 connected in sequence, and the second electrodes 1040 may be in a block shape, etc. Further, one end of the second channel 104 is connected to the second touch lead 106; that is, at this time, one second channel 104 is electrically connected to one second touch lead 106.

[0020] Alternatively, the first channel 100 may be a sensing channel, and the second channel 104 may be a driving channel; of course, in other embodiments, the first channel 100 may be a driving channel, and the second channel 104 may be a sensing channel, and the present application does not impose too many limitations on this.

[0021] The array layer 12 is stacked with the touch layer 10, including a plurality of first bonding components 120 arranged side by side, and two first touch leads 102 connected to the same first channel 100 are connected through conductive holes ( Figure 1 The black solid dots in the middle are connected to the same first bonding component 120. It should be noted that Figure 1 For the sake of clarity, the array layer 12 and the touch layer 10 are drawn in one layer. It can be known that in an actual touch display panel, the array layer 12 is stacked below the touch layer 10 .

[0022] It can be seen that the first channel 100 in the touch layer 10 provided in the present application is respectively connected to two ends in the extension direction with a first touch lead 102. This design method can reduce the resistance voltage drop on the first channel 100, which is beneficial to improving the touch accuracy; further, on this basis, the two first touch leads 102 connected to the same first channel 100 are connected to the same first bonding component 120 in the array layer 12 therebelow through conductive holes. This design method can reduce the number of first bonding components 120 required for the first channel 100, which is beneficial to reducing the border width occupied by the touch layer 10 when bonding.

[0023] In some embodiments, Figure 1 As shown, when the touch layer 10 includes the second channel 104, the array layer 12 may further include a plurality of second bonding components 122 arranged side by side, and the second touch lead 106 passes through the conductive hole ( Figure 1 The black solid dots in the middle are connected to the second bonding component 122. Further, the array layer 12 includes a bonding area 124, which is used to connect with the same flexible circuit board; wherein the bonding area 124 includes a plurality of first bonding components 120, a plurality of second bonding components 122 and a plurality of third bonding components (not shown in the figure), and the third bonding components are connected to the pixel driving circuit (not shown in the figure) in the array layer 12.

[0024] It can be seen that in the present application, while reducing the number of first bonding components 120 required for the touch layer 10, the first bonding components 120 and the second bonding components 122 of the touch layer 10 and the third bonding components corresponding to the pixel driving circuit are uniformly arranged in a bonding area 124, so that the same flexible circuit board can be bonded to the bonding area 124, thereby reducing the number of flexible circuit boards and reducing the bonding cost.

[0025] Optionally, the array layer 12 may include multiple metal layers, and the first bonding component 120, the second bonding component 122, and the third bonding component may be located at any metal layer. Figure 2 As shown, the touch display panel provided in the present application may also include other structures; for example, a substrate 14, located on the side of the array layer 12 away from the touch layer 10; for another example, a cover plate 16, located on the side of the touch layer 10 away from the array layer 12; for another example, an encapsulation layer 18, located between the touch layer 10 and the array layer 12, and in this case, the conductive hole can penetrate the encapsulation layer 18.

[0026] In some embodiments, Figure 1As shown, the first bonding component 120 includes a first bonding lead 1200 and a first bonding terminal 1202 connected to each other, and two first touch leads 102 connected to the same first channel 100 are connected to the same first bonding lead 1200 through a conductive hole. The structure of the first bonding component 120 is simple, and the wiring cost is low, which reduces the probability of redundant bonding leads occupying the frame width. Of course, in other embodiments, the first bonding component 120 may also include two first bonding leads 1200 connected to each other and a first bonding terminal 1202 connected to both first bonding leads 1200. In this case, the two first touch leads 102 connected to the same first channel 100 can be connected to one first bonding lead 1200 through a conductive hole.

[0027] Further, if Figure 1 As shown, in the extension direction of the first bonding lead 1200, the first bonding lead 1200 includes a first connection portion P1 and a second connection portion P2 that are spaced apart, and the second connection portion P2 is located between the first connection portion P1 and the first bonding terminal 1202; wherein the two first touch leads 102 connected to the same first channel 100 are respectively connected to the first connection portion P1 and the second connection portion P2 through corresponding conductive holes. That is, the two first touch leads 102 connected to the same first channel 100 are respectively connected to different positions of the first bonding lead 1200 through different conductive holes. In some embodiments, compared with the method in which the two first touch leads 102 connected to the same first channel 100 are connected to the same position of the first bonding lead 1200 through the same conductive hole, Figure 1 The above method can reduce the wiring difficulty of the first touch leads 102 in the touch layer 10 and reduce the probability of overlapping between the plurality of first touch leads 102 .

[0028] On this basis, in some embodiments, please continue to refer to Figure 1 In the first parallel direction L1 of the plurality of first bonding leads 1200 where the plurality of adjacent first connection parts P1 are located, the plurality of adjacent first connection parts P1 are arranged flush with each other. This design method can reduce the difficulty of wiring.

[0029] Alternatively, if Figure 1As shown, the first bonding lead 1200 includes a first extension portion 12000 and a second extension portion 12002 that are bent, and the end of the second extension portion 12002 that is away from the first extension portion 12000 is connected to the first bonding terminal 1202. That is, the first bonding lead 1200 is L-shaped at this time. When the first connection portion P1 is located on the first extension portion 12000, the first parallel direction L1 can be understood as the first parallel direction of the adjacent plurality of first extension portions 12000. Preferably, the first parallel direction L1 of the plurality of first extension portions 12000 is parallel to the second direction Y. The structural design of the first bonding lead 1200 is relatively simple, and the process is easy to prepare and form.

[0030] Optionally, the first connection portion P1 is one end portion of the first bonding lead 1200, for example, Figure 1 The end of the first extension part 12000 away from the second extension part 12002 forms the first connection part P1. This design method can reduce the amount of redundant first bonding wires 1200 introduced, and reduce the wiring cost of the first bonding wires 1200.

[0031] Further, if Figure 1 As shown in the figure, the orthographic projection of the first touch lead 102 connected to the first connection part P1 through the conductive hole on the array layer 12 includes a first part 1020a, the first part 1020a is adjacent to the first connection part P1, and the first part 1020a is located outside the first bonding lead 1200 and is located on the same straight line as the part of the first bonding lead 1200 where the first connection part P1 is located.

[0032] For example, Figure 1 As shown in the figure, the "first touch lead 102 connected to the first connection part P1 through the conductive hole" can be understood as the first touch lead marked as 102a connected to the uppermost end of the first channel 100; the "part of the first bonding lead 1200 where the first connection part P1 is located" can be understood as the first extension part 12000; that is, the orthographic projection of the first touch lead marked as 102a on the array layer 12 includes the first part 1020a, and the first part 1020a and the first extension part 12000 connected to it through the conductive hole are located on the same straight line.

[0033] In the above design, there is no intersection between the first portion 1020 a and the surrounding first bonding wires 1200 , which can reduce the cross-coupling capacitance between the first portion 1020 a and the underlying first bonding wires 1200 , thereby improving the touch accuracy of the touch layer 10 .

[0034] Or, if Figure 3 As shown, Figure 3 for Figure 1In the first parallel direction L1 of the plurality of first bonding leads 1200 where the plurality of adjacent first connecting portions P1 are located, the plurality of adjacent first connecting portions P1 are staggered.

[0035] For example, Figure 3 As shown, “a first side-by-side direction L1 of a plurality of first bonding leads 1200 where a plurality of first connection portions P1 are located” may be understood as: a first side-by-side direction L1 of a plurality of first extension portions 12000 including the first connection portions P1.

[0036] Since the size of the conductive hole is generally larger, for example, the size of the conductive hole is larger than the wire diameter of the first bonding lead 1200, the above-mentioned staggered arrangement can reduce the width occupied by the multiple first extension portions 12000 in the first parallel direction L1 compared to the side-by-side arrangement, which is conducive to a narrow frame.

[0037] Alternatively, if Figure 3 As shown, the first connection portion P1 is one end portion of the first bonding lead 1200; for example, Figure 3 The end of the first extension portion 12000 away from the second extension portion 12002 forms a first connection portion P1. In the first parallel direction L1, the adjacent multiple first connection portions P1 are arranged along the first oblique line M1, and the extension direction of the first oblique line M1 intersects with the first parallel direction L1; for example, the angle between the extension direction of the first oblique line M1 and the first parallel direction L1 is an acute angle, for example, the angle is 30°, 45°, or 60°. This design method can reduce the width occupied by the multiple first extension portions 12000 in the first parallel direction L1 while reducing the wiring difficulty.

[0038] Alternatively, please continue to Figure 3 The orthographic projection of the first touch lead 102 connected to the first connection portion P1 through the conductive hole on the array layer includes a first portion 1020a, the first portion 1020a is adjacent to the first connection portion P1, and the first portion 1020a and the portion of the first bonding lead 1200 where the first connection portion P1 is located intersect each other.

[0039] For example, Figure 3 As shown in the figure, the "first touch lead 102 connected to the first connection part P1 through the conductive hole" can be understood as the first touch lead marked as 102a connected to the uppermost end of the first channel 100; the "part of the first bonding lead 1200 where the first connection part P1 is located" can be understood as the first extension part 12000; that is, the orthographic projection of the first touch lead marked as 102a on the array layer 12 includes the first part 1020a, and the first part 1020a and the adjacent first extension part 12000 connected to it through the conductive hole intersect with each other.

[0040] The above design can reduce the wiring length required for the first touch lead 102 connected to the first connection portion P1 through the conductive hole, thereby reducing the wiring cost.

[0041] In some embodiments, for the second connection portion P2, Figure 3 As shown, in the second parallel direction L2 of the plurality of first bonding wires 1200 where the plurality of adjacent second connection portions P2 are located, the plurality of adjacent second connection portions P2 are arranged flush with each other.

[0042] For example, Figure 3 As shown, the second connection portion P2 may be located on the second extension portion 12002 of the first bonding lead 1200, and the second parallel direction L2 may be understood as the second parallel direction L2 of the adjacent plurality of second extension portions 12002. The flush arrangement of the adjacent plurality of second connection portions P2 may reduce wiring difficulty.

[0043] Alternatively, if Figure 3 As shown, the second connection portion P2 is located between the two ends of the first bonding lead 1200, and the orthographic projection of the first touch lead 102 connected to the second connection portion P2 through the conductive hole on the array layer includes a second portion 1020b, and the second portion 1020b is adjacent to the second connection portion P2, and the second portion 1020b covers the portion of the first bonding lead 1200 where the second connection portion P2 is located; for example, the second portion 1020b and the portion of the first bonding lead 1200 where the second connection portion P2 is located are located on the same straight line.

[0044] Specifically, Figure 3 As shown, the second connection portion P2 can be located on the second extension portion 12002 of the first bonding lead 1200; at this time, the first touch lead 102 connected to the second connection portion P2 through the conductive hole can be understood as the first touch lead labeled 102b; and the second portion 1020b can cover at least part of the second extension portion 12002.

[0045] In the above design, the second portion 1020b is equivalent to being parallel to at least a portion of the second extension portion 12002 and their orthographic projections overlap with each other, so as to reduce wiring difficulty and wiring cost.

[0046] Alternatively, see Figure 4 , Figure 4 for Figure 1 In the second parallel direction L2 of the plurality of first bonding leads 1200 where the plurality of adjacent second connection portions P2 are located, the plurality of adjacent second connection portions P2 are staggered.

[0047] For example, Figure 4 As shown, when the second connection portion P2 is located on the second extension portion 12002, "the second parallel direction L2 of the plurality of first bonding leads 1200 where the plurality of second connection portions P2 are located" can be understood as: the second parallel direction L2 of the plurality of second extension portions 12002 including the second connection portion P2. Of course, in other embodiments, such as Figure 1 As shown in , the second connection portion P2 may also be located on the first extension portion 12000. In this case, "the second parallel direction L2 of the plurality of first bonding leads 1200 where the plurality of second connection portions P2 are located" can be understood as: the first parallel direction L1 of the plurality of first extension portions 12000 including the second connection portion P2, that is, Figure 1 The first parallel direction L1 and the second parallel direction L2 are parallel to each other.

[0048] Since the size of the conductive hole is generally larger, for example, the size of the conductive hole is larger than the wire diameter of the first bonding lead 1200, the above-mentioned staggered setting method can reduce the width occupied by multiple second extension portions 12002 in the second parallel direction L2 compared to the side-by-side setting method, thereby reducing the space occupied by the wiring.

[0049] Alternatively, if Figure 4 As shown, the second connection portion P2 is between the two ends of the first bonding lead, and in the second parallel direction L2, the adjacent multiple second connection portions P2 are arranged along the second oblique line M2, and the extension direction of the second oblique line M2 intersects with the second parallel direction L2; for example, the extension direction of the second oblique line M2 and the second parallel direction L2 form an acute angle, such as 30°, 45°, or 60°. This design method can reduce the width occupied by the multiple first bonding leads 1200 in the second parallel direction L2 while reducing the wiring difficulty.

[0050] Alternatively, if Figure 4 As shown, the orthographic projection of the first touch lead 102 connected to the second connection portion P2 through a conductive hole on the array layer includes a second portion 1020b, which is adjacent to the second connection portion P2 and covers the portion of the first bonding lead 1200 where the second connection portion P2 is located.

[0051] Optionally, the second portion 1020b and the portion of the first bonding wire 1200 where the second connection portion P2 is located are located on the same straight line. Figure 4 As shown, when the second connection portion P2 is located on the second extension portion 12002 of the first bonding lead 1200 , the second portion 1020 b may be parallel to the second extension portion 12002 where the adjacent second connection portion P2 is located, and cover a portion of the second extension portion 12002 .

[0052] Alternatively, the second portion 1020b and the portion of the first bonding wire 1200 where the second connection portion P2 is located intersect each other. Figure 1 As shown, when the second connection portion P2 is located on the first extension portion 12002 of the first bonding wire 1200, the second portion 1020b may intersect with the first extension portion 12000 where the adjacent second connection portion P2 is located.

[0053] In conclusion, the above-mentioned parallel or cross design methods can reduce wiring cost and wiring difficulty.

[0054] In a specific application scenario, such as Figure 1 As shown, the first connection portion P1 and the second connection portion are both located on the first extension portion 12000, and the first connection portion P1 is located at the end of the first extension portion 12000; at this time, the first side-by-side setting direction L1 and the second side-by-side setting direction L2 are parallel to each other; the adjacent multiple first connection portions P1 are aligned with each other in the first side-by-side setting direction L1 of the multiple first extension portions 12000, and the adjacent multiple second connection portions P2 are staggered with each other in the first side-by-side setting direction L1 of the multiple first extension portions 12000.

[0055] In another specific application scenario, such as Figure 3 As shown, the first connection part P1 is located at the end of the first extension part 12000, and the second connection part P2 is located on the second extension part 12002; at this time, the first side-by-side setting direction L1 and the second side-by-side setting direction L2 intersect with each other; the adjacent multiple first connection parts P1 are staggered with each other in the first side-by-side setting direction L1 of the multiple first extension parts 12000, and the adjacent multiple second connection parts P2 are aligned with each other in the second side-by-side setting direction L2 of the multiple second extension parts 12002.

[0056] In another specific application scenario, such as Figure 4 As shown, the first connection part P1 is located at the end of the first extension part 12000, and the second connection part P2 is located on the second extension part 12002; at this time, the first side-by-side arrangement direction L1 and the second side-by-side arrangement direction L2 intersect with each other; the adjacent multiple first connection parts P1 are staggered with each other in the first side-by-side arrangement direction L1 of the multiple first extension parts 12000, and the adjacent multiple second connection parts P2 are staggered with each other in the second side-by-side arrangement direction L2 of the multiple second extension parts 12002.

[0057] In another specific application scenario, such as Figure 5 As shown, Figure 5 for Figure 1A schematic diagram of another embodiment of the first bonding component and the first touch lead. The first connection portion P1 is located at the end of the first extension portion 12000, and the second connection portion P2 is located on the second extension portion 12002; at this time, the first parallel arrangement direction L1 and the second parallel arrangement direction L2 intersect each other; the adjacent plurality of first connection portions P1 are arranged flush with each other in the first parallel arrangement direction L1 of the plurality of first extension portions 12000, and the adjacent plurality of second connection portions P2 are arranged flush with each other in the second parallel arrangement direction L2 of the plurality of second extension portions 12002.

[0058] In addition, although Figure 1 , Figure 3 , Figure 4 , Figure 5 The first connection portion P1 is connected to the first touch lead 102a through a conductive hole, and the second connection portion P2 is connected to the first touch lead 102b through a conductive hole. Figure 6 As shown, Figure 6 for Figure 1 Schematic diagram of the structure of another embodiment of the first bonding component and the first touch lead, the first connecting portion P1 can also be connected to the first touch lead labeled 102b through a conductive hole, and the second connecting portion P2 can also be connected to the first touch lead labeled 102a through a conductive hole.

[0059] Also, please refer again to Figure 1 The second bonding component 122 includes a second bonding lead 1220 and a second bonding terminal 1222 connected to each other, and the second touch lead 106 connected to the second channel 104 is connected to the second bonding lead 1220 through a conductive hole. The second bonding component 122 has a simple structure and a low wiring cost.
