[0055] With the continuous development of technology, conductive grids are being used in various fields due to their advantages such as low impedance and bending resistance, especially in the touch field, bringing a new experience to laptops, tablets, learning machines or car displays.

[0056] In the design process of the conductive grid, it is necessary to design related circuits based on the conductive grid to achieve related functions. Generally, the conductive grid area that transmits signals is designed as the signal channel area (channel area), and the conductive grid area where the signal is not connected is designed as the virtual routing area (dummy area). Among them, the signal channel areas are generally insulated and separated by the virtual routing area. Due to factors such as preparation process and product design, there will be some differences between the signal channel area and the virtual routing area. These differences will be reflected in the appearance of color difference problems, especially the outline traces of the signal channel area and the virtual routing area on the conductive grid, that is, the channel trace.

[0057] After research, it was found that in related technologies, a dense interruption method is usually used on the virtual routing area to make the electrical isolation property of the virtual routing area better. However, this will lead to too many interruption points on the virtual routing area, which will lead to a large color difference between the signal channel area of ​​the conductive grid and the virtual routing area, especially the problem of channel marks.

[0058] Based on this, the present application designs a conductive grid 10 to solve the problem of large color difference between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10 .

[0059] Figure 1-Figure 5 Schematic diagrams of partial structures of the conductive grid 10 in different embodiments of the present application are shown.

[0060] See also Figure 1-Figure 5 An embodiment of the present application provides a conductive grid 10, which includes a plurality of first conductive lines 110 and a plurality of second conductive lines 120. The first conductive lines 110 and the second conductive lines 120 are cross-connected to form a continuous grid, and the first conductive lines 110 and the second conductive lines 120 intersect at a vertex 101.

[0061] The continuous grid includes a virtual routing area 100 and a signal channel area 200 , and adjacent signal channel areas 200 are separated by the virtual routing area 100 .

[0062] Specifically, in the signal channel region 200 , a plurality of first conductive lines 110 and a plurality of second conductive lines 120 are cross-connected to form a plurality of closed grid structures 201 .

[0063] A virtual interruption line L2 extending along the longitudinal extension direction of the virtual routing area 100 is provided between the virtual routing area 100 and the adjacent signal channel area 200 , so that a whole interruption structure extending along the longitudinal extension direction of the virtual routing area 100 is formed between the virtual routing area 100 and the adjacent signal channel area 200 .

[0064] The virtual routing area 100 is provided with a plurality of disconnected portions D0. Specifically, the disconnected portion D0 is located between two adjacent vertex portions 101. In order to conveniently illustrate the position of the disconnected portion D0, Figure 1-Figure 5 A plurality of position marks B corresponding one to one with the disconnection portion D0 are provided, and the position of the corresponding disconnection portion D0 can be understood according to the position mark B.

[0065] The plurality of disconnected portions D0 divide the virtual routing area 100 into a plurality of mutually insulated sub-partition units 1001 , wherein each sub-partition unit 1001 includes at least two vertex portions 101 .

[0066] Since multiple sub-partition units 1001 are insulated from each other, the requirements for electrical isolation performance of the virtual routing area 100 can be met; and since the sub-partition unit 1001 includes at least two vertex parts 101, the virtual routing area 100 is not densely interrupted by multiple disconnection parts D0. In this way, while meeting the electrical isolation performance of the virtual routing area 100, it is helpful to improve the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem. In addition, this solution is applicable to virtual routing areas 100 of any size, and the setting of the disconnection part D0 is more compatible, which can achieve the improvement of the color difference problem.

[0067] It should be supplemented that the sub-partition unit 1001 can be divided according to the distribution direction of the multiple disconnected portions D0, and "the sub-partition unit 1001 includes at least two vertex portions 101" can mean that the sub-partition unit 1001 includes at least two vertex portions 101 that are conductive to each other, or that the sub-partition unit 1001 includes at least two vertex portions 101 that are not conductive to each other; in the present application, while satisfying the requirement of "the sub-partition unit 1001 includes at least two vertex portions 101 that are conductive to each other" as much as possible, it is also allowed to have "the sub-partition unit 1001 includes at least two vertex portions 101 that are not conductive to each other", that is, preferably, all or most of the vertex portions 101 in the sub-partition unit 1001 are conductive to each other, so as to reduce the setting of the disconnected portion D0 in the virtual routing area 100, thereby improving the color difference problem between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10.

[0068] In some embodiments, the redundancy of the virtual routing area 100 is positively correlated with the number of disconnected portions D0, and the redundancy is the number of complete mesh edges 102a of the virtual routing area 100 in a direction perpendicular to the longitudinal extension direction of the virtual routing area 100. Specifically, a plane perpendicular to the longitudinal extension direction of the virtual routing area 100 and not passing through the vertex portion 101 is defined as the measurement plane C, and the redundancy of the virtual routing area 100 is the number of complete mesh edges 102a intersecting the measurement plane C. The complete mesh edge 102a is a mesh edge 102 located in the virtual routing area 100, and the mesh edge 102 includes two vertex portions 101 adjacent to each other along the longitudinal extension direction of the first conductive line 110 or the second conductive line 120, and a portion located between the two vertex portions 101.

[0069] The redundancy of the virtual routing area 100 is positively correlated with the number of disconnected portions D0 , that is, the greater the redundancy of the virtual routing area 100 , the greater the number of disconnected portions D0 , and the smaller the redundancy of the virtual routing area 100 , the smaller the number of disconnected portions D0 .

[0070] Since the grid edge 102 includes two adjacent vertices 101 along the longitudinal extension direction of the first conductive line 110 or the second conductive line 120, and a portion located between the two vertices 101, when the redundancy of the virtual routing area 100 is large, the number of grid edges 102 intersecting with the measuring surface C is large, which means that there are more paths for signals to pass through on the virtual routing area 100, and more disconnection portions D0 can be set on the virtual routing area 100 to better meet the requirements of the electrical isolation performance of the virtual routing area 100; and when the redundancy of the virtual routing area 100 is small, the number of grid edges 102 intersecting with the measuring surface C is large. If the number of grid edges 102 intersecting the measuring surface C is small, it means that there are fewer paths for signals to pass through on the virtual routing area 100, and fewer disconnected portions D0 can be set on the virtual routing area 100, which can also meet the electrical isolation performance requirements of the virtual routing area 100; in this way, a suitable number of disconnected portions D0 can be opened on the virtual routing area 100 according to the redundancy of the virtual routing area 100, which is beneficial to improve the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem, while meeting the electrical isolation performance of the virtual routing area 100.

[0071] In some embodiments, the redundancy of the dummy routing area 100 is positively correlated with the arrangement density of the disconnected portions D0 .

[0072] That is to say, the greater the redundancy of the virtual routing area 100, the greater the arrangement density of the disconnection portion D0, and the smaller the redundancy of the virtual routing area 100, the smaller the arrangement density of the disconnection portion D0. In this way, a suitable number of disconnection portions D0 can be opened on the virtual routing area 100 according to the redundancy of the virtual routing area 100, which is conducive to improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem, while satisfying the electrical isolation performance of the virtual routing area 100. In addition, since the redundancy of the virtual routing area 100 is positively correlated with the arrangement density of the disconnection portion D0, a plurality of disconnection portions D0 can be evenly arranged on at least a part of the area of ​​the virtual routing area 100 according to actual conditions, which is also conducive to improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0073] In some embodiments, the grid edges 102 in the sub-partition unit 1001 are electrically connected to each other, wherein the grid edge 102 includes two adjacent vertices 101 along the longitudinal extension direction of the first conductive line 110 or the second conductive line 120 , and a portion between the two vertices 101 .

[0074] It can be understood that there is no disconnection portion D0 in the sub-partition unit 1001. In this way, while satisfying the electrical isolation performance of the virtual routing area 100, the situation where too many disconnection portions D0 are opened in the virtual routing area 100 can be further reduced, which is beneficial to improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0075] In some embodiments, at most one disconnected portion D0 is disposed on the same grid edge 102 in the virtual routing area 100 .

[0076] Through research, it is found that due to the over-dense interruption, more isolated first conductive lines 110 or second conductive lines 120 will appear, and these isolated conductive lines are more likely to produce channel marks. Based on this, the present application has at most one disconnection portion D0 on the same grid edge 102, that is, only one disconnection portion D0 is provided on a grid edge 102, so as to avoid the occurrence of a single isolated first conductive line 110 or second conductive line 120, which is conducive to improving the color difference problem between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10, especially the channel mark problem.

[0077] In some embodiments, at least two of the sub-partitioning units 1001 are spaced between two adjacent signal channel areas 200 .

[0078] Since there are at least two sub-partition units 1001 between two adjacent signal channel areas 200, that is, the partition between two adjacent signal channel areas 200 has passed through at least two layers of partition, namely, two sub-partition units 1001. Therefore, when any sub-partition unit 1001 of the two sub-partition units 1001 and the signal channel area 200 on one side are abnormally connected, the signal channel area 200 and the signal channel area 200 on the other side can still be electrically isolated from each other, which is beneficial to improving the electrical isolation performance of the virtual routing area 100.

[0079] In some embodiments, the dimension of each sub-partition unit 1001 along the longitudinal extension direction of the virtual routing area 100 is H1, and the distance between two adjacent apex portions 101 along the longitudinal extension direction of the virtual routing area 100 is H2, and H1≥H2.

[0080] Optionally, H2≤H1≤1.5*H2. For example, H1 is equal to H2, 1.1*H2, 1.2*H2, 1.3*H2, 1.4*H2 or 1.5*H2.

[0081] Alternatively, H2≤H1≤n*H2, where n depends on the actual design of the grid pattern, e.g. Figure 1 The grid pattern design shown in the figure has a F 纵 The mesh size in the direction is larger than F宽 The grid size in the direction, then n can be selected to be 1.5. In addition, if Figure 1 Medium F 纵 The grid size in the direction is less than or equal to F 宽 If n is the grid size in the direction, then n can be chosen to be 2 or 2.5.

[0082] It should be noted that, depending on process deviations, if H1 is less than and approximately equal to H2, H1 can also be considered to be equal to H2.

[0083] Since H1≥H2, it can be understood that along the longitudinal extension direction of the virtual routing area 100, the distance between two adjacent disconnected portions D0 is relatively large, which is beneficial to reducing the arrangement density of the disconnected portions D0, thereby reducing the situation where the virtual routing area 100 is densely interrupted by multiple disconnected portions D0, and thus is beneficial to improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0084] In some embodiments, Figure 1-Figure 4 As shown, the sub-partition unit 1001 includes at least one complete grid edge 102 a , wherein the complete grid edge 102 a is a grid edge 102 located in the virtual routing area 100 .

[0085] It may be that some of the sub-partition units 1001 include at least one complete mesh edge 102 a , or it may be that any of the sub-partition units 1001 includes at least one complete mesh edge 102 a .

[0086] It can be understood that the sub-partition unit 1001 includes at least one complete grid edge 102a and two vertex portions 101 at both ends thereof, so that the virtual routing area 100 is not densely interrupted by multiple disconnected portions D0, which is beneficial to improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0087] In some embodiments, in each sub-partition unit 1001 , at least two apex portions 101 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100 .

[0088] It can be that the sub-partition unit 1001 is provided with two apex portions 101, and the two apex portions 101 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100; it can also be that the sub-partition unit 1001 is provided with three apex portions 101, of which two apex portions 101 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100. Of course, it can also be that the sub-partition unit 1001 is provided with four or more apex portions 101, of which two apex portions 101 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100.

[0089] In this way, at least two vertex portions 101 can be provided between two adjacent disconnected portions D0, so that the distance between the two adjacent disconnected portions D0 is larger, which is beneficial to reducing the arrangement density of the disconnected portions D0, thereby reducing the situation where the virtual routing area 100 is densely interrupted by multiple disconnected portions D0, and thus is beneficial to improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0090] In some embodiments, the width of the virtual routing area 100 is a dimension of the virtual routing area 100 along a direction perpendicular to the longitudinal extension direction of the virtual routing area 100 and perpendicular to the thickness direction of the virtual routing area 100 .

[0091] Figure 1 In the figure, the longitudinal extension direction of the virtual routing area 100 is marked as F 纵 , the width direction of the virtual routing area 100 is marked as F 宽 .

[0092] Optionally, the disconnection portion D0 is longitudinally extended from one end to the other end along the width direction of the virtual routing area 100 .

[0093] Generally, the smaller the width of the virtual routing area 100, the fewer paths available for signals to pass through the virtual routing area 100, that is, the smaller the redundancy of the virtual routing area 100. At this time, while satisfying the electrical isolation performance of the virtual routing area 100, fewer disconnected portions D0 can be opened in the virtual routing area 100, such as making the size of the sub-partition unit 1001 along the longitudinal extension direction of the virtual routing area 100 larger, which is conducive to opening fewer disconnected portions D0 in the virtual routing area 100, so as to improve the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem, while satisfying the electrical isolation performance of the virtual routing area 100.

[0094] like Figure 1 As shown, in some embodiments, a plurality of disconnection portions D0 are arranged to form a plurality of first disconnection portion groups D1 arranged along the longitudinal extension direction of the virtual wiring area 100, and a plurality of second disconnection portion groups D2, each second disconnection portion group D2 is located between two adjacent first disconnection portion groups D1, and the disconnection portions D0 of each first disconnection portion group D1 are arranged at intervals along a direction perpendicular to the longitudinal extension direction of the virtual wiring area 100 and perpendicular to the thickness direction of the virtual wiring area 100. The disconnection portions D0 of each second disconnection portion group D2 are arranged along the longitudinal extension direction of the virtual wiring area 100.

[0095] In this embodiment, along the longitudinal extension direction of the virtual routing area 100 , the distance between two adjacent apex portions 101 is H2 , and the distance between adjacent disconnected portions D0 in the adjacent first disconnected portion group D1 is greater than or equal to H2 .

[0096] In this embodiment, the redundancy of the virtual routing area 100 is greater than or equal to 3.

[0097] Figure 1 An example is given where the redundancy of the virtual routing area 100 is 6, such as Figure 1 In the illustrated embodiment, each first disconnection section group D1 includes six disconnection sections D0, which can be understood in conjunction with the position marks B corresponding to the multiple disconnection sections D0 of the first disconnection section group D1. The second disconnection section group D2 includes one disconnection section D0, which can also be understood in conjunction with the position marks B corresponding to the disconnection sections D0 of the second disconnection section group D2.

[0098] Since the spacing between adjacent disconnected portions D0 in adjacent first disconnected portion groups D1 is greater than or equal to H2, the first disconnected portion group D1 is equivalent to being arranged along the width direction of the virtual routing area 100, and the spacing between two adjacent first disconnected portion groups D1 is larger, and the number of disconnected portions D0 in the second disconnected portion group D2 between two adjacent first disconnected portion groups D1 is smaller, which can reduce the situation where multiple disconnected portions D0 are densely arranged on the virtual routing area 100, thereby improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0099] In this embodiment, adjacent first disconnected portion groups D1 are separated by at least one grid edge 102 .

[0100] Since the spacing between adjacent first disconnection portion groups D1 is large, the dispersion of multiple first disconnection portion groups D1 on the virtual routing area 100 can be improved, thereby reducing the situation where multiple disconnection portions D0 are densely arranged on the virtual routing area 100, thereby improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0101] In some embodiments, the multiple disconnecting parts D0 of the same first disconnecting part group D1 are symmetrically arranged with the first symmetric center line L1 as a reference object, and the disconnecting parts D0 of the second disconnecting part group D2 are arranged along the first symmetric center line L1. The second disconnecting part group D2 can be offset slightly relative to the first symmetric center line L1 according to actual conditions.

[0102] In some other embodiments, along a direction perpendicular to the longitudinal extension direction of the virtual wiring area 100 and perpendicular to the thickness direction of the virtual wiring area 100 , two adjacent groups of second disconnecting portions D2 are staggered.

[0103] In this way, to a certain extent, the regularity of the arrangement of the multiple disconnected portions D0 on the virtual routing area 100 can be reduced, that is, it appears more disordered, so as to reduce the obviousness of the disconnected portions D0, which is beneficial to improve the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0104] In this embodiment, multiple disconnect portions D0 of the same first disconnect portion group D1 are symmetrically arranged with the first symmetry center line L1 as a reference object, and along a direction perpendicular to the longitudinal extension direction of the virtual routing area 100 and perpendicular to the thickness direction of the virtual routing area 100, two adjacent groups of second disconnect portion groups D2 are located on opposite sides of the first symmetry center line L1.

[0105] Of course, the present application is not limited thereto, and in other embodiments, the second disconnecting portion group D2 may also be symmetrically arranged with the first symmetry center line L1 as a reference object.

[0106] In this way, the plurality of disconnected portions D0 can be arranged more regularly, thereby improving the color difference problem between the signal channel area 200 and the dummy wiring area 100 of the conductive grid 10, especially the channel mark problem. Figure 2 As shown, in other embodiments, a plurality of disconnection portions D0 are arranged to form a plurality of third disconnection portion groups D3 and a plurality of fourth disconnection portion groups D4. Along the longitudinal extension direction of the virtual routing area 100, the third disconnection portion group D3 and the fourth disconnection portion group D4 are arranged alternately. The disconnection portions D0 of the third disconnection portion group D3 are arranged at intervals along the first direction F1, and the disconnection portions D0 of the fourth disconnection portion group D4 are arranged at intervals along the second direction F2. The first direction F1 is set at an angle to the second direction F2, and both are set at an angle to the longitudinal extension direction of the virtual routing area 100. It can be that the first direction F1 is parallel to the longitudinal extension direction of the first conductive line 110, and the second direction F2 is parallel to the longitudinal extension direction of the second conductive line 120. It can also be that the first direction F1 is parallel to the longitudinal extension direction of the second conductive line 120, and the second direction F2 is parallel to the longitudinal extension direction of the first conductive line 110.

[0107] In this embodiment, the redundancy of the virtual routing area 100 is equal to 2.

[0108] Since the third disconnection portion group D3 and the fourth disconnection portion group D4 are arranged alternately, the disconnection portion D0 of the third disconnection portion group D3 changes its spacing arrangement direction relative to the disconnection portion D0 in the adjacent fourth disconnection portion group D4, which is beneficial for the multiple disconnection portions D0 to be opened more dispersedly on the virtual routing area 100, and further beneficial for improving the color difference problem between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10, especially the channel mark problem.

[0109] In this embodiment, the disconnection parts D0 of the third disconnection part group D3 may be respectively arranged on the adjacent first conductive lines 110, and the disconnection parts D0 of the fourth disconnection part group D4 may be respectively arranged on the adjacent second conductive lines 120, for example, the two disconnection parts D0 of the third disconnection part group D3 may be respectively arranged on the two adjacent first conductive lines 110, and the two disconnection parts D0 of the fourth disconnection part group D4 may be respectively arranged on the two adjacent second conductive lines 120; it may also be that the disconnection parts D0 of the third disconnection part group D3 may be respectively arranged on the adjacent second conductive lines 120, and the disconnection parts D0 of the fourth disconnection part group D4 may be respectively arranged on the adjacent first conductive lines 110, for example, the two disconnection parts D0 of the third disconnection part group D3 may be respectively arranged on the two adjacent second conductive lines 120, and the two disconnection parts D0 of the fourth disconnection part group D4 may be respectively arranged on the two adjacent first conductive lines 110.

[0110] Specific to Figure 2 In the embodiment shown, the first direction F1 is parallel to the longitudinal extension direction of the second conductive line 120, and the second direction F2 is parallel to the longitudinal extension direction of the first conductive line 110. The two disconnecting portions D0 of the third disconnecting portion group D3 are respectively arranged on two adjacent first conductive lines 110, and the two disconnecting portions D0 of the fourth disconnecting portion group D4 are respectively arranged on two adjacent second conductive lines 120.

[0111] Specific to Figure 2 In the illustrated embodiment, the sub-partition unit 1001 is roughly in a triangular structure, and the whole formed by two adjacent sub-partition units 1001 is roughly in a parallelogram structure.

[0112] In this way, two adjacent sub-partition units 1001 can be disconnected by two disconnection parts D0 of the same third disconnection part group D3, or by two disconnection parts D0 of the same fourth disconnection part group D4, so that at least two sub-partition units 1001 are spaced apart from two adjacent signal channel areas 200, which is beneficial to improving the electrical isolation performance of the virtual routing area 100, that is, when any sub-partition unit 1001 of the two sub-partition units 1001 and the signal channel area 200 on one side are abnormally conductive, the signal channel area 200 and the signal channel area 200 on the other side can still be electrically isolated from each other.

[0113] like Figure 4 As shown, in some other embodiments, a plurality of disconnected portions D0 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100 , and any two adjacent disconnected portions D0 are separated by two vertices 101 or a grid edge 102 .

[0114] In this embodiment, the redundancy of the virtual routing area 100 is equal to 1.

[0115] That is to say, along the longitudinal extension direction of the virtual routing area 100, a disconnection portion D0 is set for every other complete grid edge 102a. Since the redundancy of the virtual routing area 100 is small, two vertex portions 101 or a grid edge 102 are set between any two adjacent disconnections D0. This is beneficial for reducing the arrangement density of the disconnections D0, and can improve the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem, while meeting the electrical isolation performance of the virtual routing area 100.

[0116] like Figure 3 and Figure 5 As shown, in some other embodiments, the virtual routing area 100 includes a first type of area 100a and a second type of area 100b, and the redundancy of the first type of area 100a and the second type of area 100b is different, wherein, Figure 3 and Figure 5 The horizontal dotted line dividing the virtual routing area represents the boundary between the first type area 100a and the second type area 100b.

[0117] Since the design of the conductive grid 10 has a random amount, the grid randomness can be divided into random spacing and random vertices. In the random spacing, the distances between adjacent first conductive lines and adjacent second conductive lines are different. In the random vertices, the vertices where the first conductive line and the second conductive line intersect are randomly distributed within the allowable range. These will cause the redundancy to be different in different regions, that is, the redundancy of different regions of the virtual routing area 100 is different. Therefore, the arrangement of the disconnection parts D0 in the corresponding region can be set according to the redundancy of different regions. In this way, it is beneficial to open a suitable number of disconnection parts D0 on the first type of area 100a and the second type of area 100b of the virtual routing area 100. Under the condition of meeting the electrical isolation performance of the virtual routing area 100, it is more beneficial to reduce the situation where too many disconnection parts D0 are opened on the virtual routing area 100, thereby better improving the color difference problem between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10, especially the channel mark problem.

[0118] like Figure 3 As shown, in some embodiments, the redundancy of the first type area 100a is 2, and the redundancy of the second type area 100b is 1.

[0119] Multiple disconnection portions D0 are arranged to form multiple groups of fifth disconnection portion groups D5, multiple groups of sixth disconnection portion groups D6 and multiple groups of seventh disconnection portion groups D7. In the first type of area 100a, the fifth disconnection portion group D5 and the sixth disconnection portion group D6 are alternately arranged along the longitudinal extension direction of the virtual routing area 100; in the second type of area 100b, the disconnection portion D0 of the seventh disconnection portion group D7 is arranged on the complete edge 102a of the grid.

[0120] Along the direction perpendicular to the longitudinal extension direction of the virtual wiring area 100 and perpendicular to the thickness direction of the virtual wiring area 100, the fifth disconnection portion group D5 and the adjacent sixth disconnection portion group D6 are arranged alternately. It can be understood that the multiple groups of fifth disconnection portion groups D5 and the multiple groups of sixth disconnection portion groups D6 are arranged in an S shape (according to Figure 2 (for understanding from the arrangement of the disconnecting portion D0 shown).

[0121] At least two disconnect portions D0 of the fifth disconnect portion group D5 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100, and at least two disconnect portions D0 of the sixth disconnect portion group D6 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100. The number of disconnect portions D0 of the fifth disconnect portion group D5 and the sixth disconnect portion group D6 is two, and the number of disconnect portions D0 of the seventh disconnect portion group D7 is at least four.

[0122] Since the disconnection portion D0 of the seventh disconnection portion group D7 is disposed on the complete grid edge 102a, the occurrence of isolated first conductive lines 110 or second conductive lines 120 can be reduced, and the occurrence of dense interruptions in the virtual routing area 100 can also be reduced. In this way, while satisfying the electrical isolation performance of the virtual routing area 100, it is more conducive to reducing the occurrence of too many disconnection portions D0 in the virtual routing area 100, thereby better improving the color difference problem between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100, especially the channel mark problem.

[0123] like Figure 5 and Figure 6 As shown, in other embodiments, the redundancy of the first type of region 100a is 1, the redundancy of the second type of region 100b is 0, the disconnected portion D0 is provided on the complete edge 102a of the grid in the first type of region 100a, and when at least two disconnected portions D0 are provided in the first type of region 100a, two adjacent disconnected portions D0 are separated by two vertex portions 101 or a grid edge 102.

[0124] On the one hand, since the disconnection portion D0 is provided on the complete grid edge 102a in the first type of area 100a, the situation where the virtual routing area 100 is densely interrupted in the first type of area 100a can be reduced. It can also be understood that the second type of area 100b is not provided with the disconnection portion D0. This is because the redundancy of the second type of area 100b is 0, that is, there is no grid edge 102 in the second type of area 100b, and a closed conductive line cannot be formed in the second type of area 100b. Therefore, there is no need to provide a disconnection portion D0 in the second type of area 100b. On the other hand, when at least two vertices 101 are provided in the first type of area 100a, two vertices 101 or a grid edge 102 are provided between two adjacent disconnected portions D0, so that the disconnected portions D0 can be arranged more dispersedly in the first type of area 100a; in this way, while meeting the electrical isolation performance of the virtual routing area 100, the number of disconnected portions D0 can be reduced, thereby improving the color difference problem between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10, especially the channel mark problem.

[0125] An embodiment of the present application provides a touch sensor, comprising at least a first conductive grid 10a and a second conductive grid 10b which are stacked and spaced apart from each other, and at least one of the first conductive grid 10a and the second conductive grid 10b is the above-mentioned conductive grid 10. The disconnection portion D0 of one of the first conductive grid 10a and the second conductive grid 10b having a disconnection portion D0 is disposed at an overlapping intersection of conductive lines in the first conductive grid 10a and the second conductive grid 10b.

[0126] like Figure 7 As shown, the longitudinal extension direction of the disconnection portion D0 of one of the first conductive mesh 10a and the second conductive mesh 10b having the disconnection portion D0 intersects with the portion of the other of the first conductive mesh 10a and the second conductive mesh 10b corresponding to the disconnection portion D0.

[0127] Specific to Figure 7 In the illustrated embodiment, the first conductive grid 10a is located on the upper layer of the second conductive grid 10b, and a plurality of disconnected portions D0 are provided on the first conductive grid 10a. The disconnected portions D0 on the first conductive grid 10a and the portions of the second conductive grid 10b corresponding to the disconnected portions D0 are intersected. In this way, the degree of apparentness of the disconnected portions D0 is further reduced, thereby improving the problem of large color difference between the dummy routing area 100 and the signal channel area 200.

[0128] Of course, the present application is not limited thereto, and the first conductive grid 10a may be located in a lower layer of the second conductive grid 10b, or a plurality of disconnected portions D0 may be provided on both the first conductive grid 10a and the second conductive grid 10b, as long as the disconnected portions D0 on the first conductive grid 10a and the portions of the second conductive grid 10b corresponding to the disconnected portions D0 are intersected, and the disconnected portions D0 on the second conductive grid 10b and the portions of the first conductive grid 10a corresponding to the disconnected portions D0 are intersected.

[0129] In this way, the disconnected portion D0 on the first conductive grid 10a can be arranged with reference to the layout of the second conductive grid 10b, and the disconnected portion D0 on the second conductive grid 10b can be arranged with reference to the layout of the first conductive grid 10a. Both the first conductive grid 10a and the second conductive grid 10b can adopt the same series of interruption patterns, which can reduce the complexity of the system.

[0130] An embodiment of the present application also discloses a touch display, including the above-mentioned touch sensor and display unit, the touch sensor is arranged on one side of the display unit, and the touch display also includes a packaging layer covering the display unit. The touch sensor may be arranged on a side of the packaging layer away from the display unit to achieve on-screen touch; or the touch sensor may be arranged on a side of the packaging layer close to the display unit to achieve in-screen touch.

[0131] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0132] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
