With the continuous development of technology, the conductive grid has the advantages of low impedance, bending resistance and the like, is applied to various fields, particularly the touch field, and brings brand new experience for notebook computers, tablet computers, learning machines or vehicle-mounted display screens and the like.
In the design process of the conductive grid, related circuits are required to be designed based on the conductive grid so as to realize related functions, a conductive grid area for transmitting signals is generally designed as a signal channel area (channel area), and a conductive grid area for not communicating signals is designed as a virtual wiring area (dummy area), wherein the signal channel areas are generally insulated and separated through the virtual wiring area. Due to factors such as a preparation process, product design and the like, some differences exist between the signal channel region and the virtual wiring region, and the differences appear in appearance, so that color difference problems can occur, and particularly contour traces, namely channel traces, of the signal channel region and the virtual wiring region on the conductive grid can be seen.
According to research, in the related art, a dense breaking mode is generally adopted on the virtual wire-walking area to break, so that the electric partition attribute of the virtual wire-walking area is good, however, the breaking points on the virtual wire-walking area are too many, and further the problem of larger chromatic aberration, particularly the problem of channel marks, exists between the signal channel area of the conductive grid and the virtual wire-walking area.
Based on this, the application designs a conductive grid 10, which aims to solve the problem that the color difference between the signal channel area 200 and the virtual wiring area 100 of the conductive grid 10 is larger.
Fig. 1-5 show schematic partial structures of conductive grids 10 in various embodiments of the present application.
Referring to fig. 1-5, an embodiment of the present application provides a conductive mesh 10, where the conductive mesh 10 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 connected in a crossing manner to form a continuous mesh, and the first conductive lines 110 and the second conductive lines 120 intersect at an apex 101.
The continuous grid comprises a virtual wiring area 100 and a signal channel area 200, and adjacent signal channel areas 200 are separated by the virtual wiring area 100.
Specifically, on the signal channel region 200, the plurality of first conductive lines 110 and the plurality of second conductive lines 120 are cross-connected to form a plurality of closed mesh structures 201.
A virtual breaking line L2 extending along the longitudinal extension direction of the virtual wire-running area 100 is disposed between the virtual wire-running area 100 and the adjacent signal channel area 200, so that an entire breaking structure extending along the longitudinal extension direction of the virtual wire-running area 100 is formed between the virtual wire-running area 100 and the adjacent signal channel area 200.
The virtual routing area 100 is provided with a plurality of breaking portions D0, and specifically, the breaking portions D0 are located between two adjacent vertex portions 101. For convenience of illustrating the position of the breaking portion D0, fig. 1 to 5 show a plurality of position marks B in one-to-one correspondence with the breaking portion D0, and the position of the corresponding breaking portion D0 can be understood from the position marks B.
The plurality of breaking portions D0 divide the virtual routing area 100 into a plurality of mutually insulated sub-partition units 1001, wherein at least two vertex portions 101 are included in the sub-partition units 1001.
Because the plurality of sub-partition units 1001 are insulated from each other, the requirement of the electrical partition performance of the virtual wire area 100 can be met, and because the sub-partition units 1001 at least comprise two vertex parts 101, the virtual wire area 100 is not densely interrupted by the plurality of disconnecting parts D0, and thus, the color difference problem, especially the problem of channel marks, between the signal channel area 200 and the virtual wire area 100 of the conductive grid 10 can be advantageously improved under the condition that the electrical partition performance of the virtual wire area 100 is met. In addition, the scheme is suitable for the virtual wiring area 100 with any size, the setting compatibility of the disconnection part D0 is stronger, and the improvement of the chromatic aberration problem can be realized.
It should be noted that the sub-partition unit 1001 may be divided according to the distribution direction of the plurality of breaking portions D0, where the sub-partition unit 1001 includes at least two of the breaking portions 101", the sub-partition unit 1001 includes at least two of the breaking portions 101 that are electrically connected to each other, or the sub-partition unit 1001 includes at least two of the breaking portions 101 that are electrically disconnected from each other, and in the present application, it is allowed that the sub-partition unit 1001 includes at least two of the breaking portions 101 that are electrically disconnected from each other, i.e., preferably, all or most of the breaking portions 101 in the sub-partition unit 1001 are electrically connected to each other, so as to reduce the arrangement of the breaking portions 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.
In some embodiments, the redundancy of the virtual wire area 100 is positively related to the number of the breaks D0, and the redundancy is the number of the grid complete sides 102a of the virtual wire area 100 in the direction perpendicular to the lengthwise extending direction of the virtual wire area 100. Specifically, a plane perpendicular to the longitudinal extension direction of the virtual wire region 100 and not passing through the vertex 101 is defined as a measurement plane C, the redundancy of the virtual wire region 100 is the number of grid complete sides 102a intersecting the measurement plane C, the grid complete sides 102a are grid sides 102 located in the virtual wire region 100, and the grid sides 102 include two vertex 101 adjacent to each other along the longitudinal extension direction of the first conductive wire 110 or the second conductive wire 120, and a portion located between the two vertex 101.
The redundancy of the virtual wire area 100 is positively correlated with the number of the disconnection portions D0, that is, the greater the redundancy of the virtual wire area 100, the greater the number of the disconnection portions D0, the smaller the redundancy of the virtual wire area 100, and the fewer the number of the disconnection portions D0.
Because the grid edge 102 includes two vertex portions 101 adjacent to each other along the longitudinal extending direction of the first conductive wire 110 or the second conductive wire 120, and a portion located between the two vertex portions 101, when the redundancy of the virtual wire routing area 100 is greater, the number of grid edges 102 intersecting with the measurement surface C is greater, which means that the number of paths on the virtual wire routing area 100 through which signals can pass is greater, more breaking portions D0 can be provided on the virtual wire routing area 100 to better satisfy the requirement of the electrical isolation performance of the virtual wire routing area 100, while when the redundancy of the virtual wire routing area 100 is smaller, the number of grid edges 102 intersecting with the measurement surface C is smaller, which means that the number of paths on the virtual wire routing area 100 through which signals can pass is smaller, and the fewer breaking portions D0 can be provided on the virtual wire routing area 100, and also satisfy the requirement of the electrical isolation performance of the virtual wire routing area 100, so that a suitable number of breaking portions D0 can be provided on the virtual wire routing area 100 according to the redundancy of the virtual wire routing area 100, and the electrical isolation performance of the virtual wire routing area 100 is satisfied, and the problem of the electrical isolation performance of the grid 100 is improved, especially, and the problem of the electrical isolation performance of the grid is improved, and the electrical isolation channel is the problem of the channel 10.
In some embodiments, the redundancy of the virtual routing area 100 is positively correlated with the arrangement density of the disconnection D0.
That is, the greater the redundancy of the virtual wire region 100, the greater the arrangement density of the disconnection portions D0, and the smaller the redundancy of the virtual wire region 100, the smaller the arrangement density of the disconnection portions D0. In this way, a suitable number of the breaking portions D0 may be formed on the virtual wire-running area 100 according to the redundancy of the virtual wire-running area 100, which is beneficial to improve the color difference problem, especially the problem of the channel mark, between the signal channel area 200 of the conductive grid 10 and the virtual wire-running area 100 under the condition of meeting the electrical isolation performance of the virtual wire-running area 100. In addition, since the redundancy of the virtual trace area 100 is positively related to the arrangement density of the breaking portions D0, a plurality of breaking portions D0 can be uniformly arranged on at least a partial area of the virtual trace area 100 according to the actual situation, which is also beneficial to improving the color difference problem, especially the problem of the channel mark, between the signal channel area 200 of the conductive mesh 10 and the virtual trace area 100.
In some embodiments, the grid edges 102 within the child partition units 1001 are in electrical communication with each other. The grid edge 102 includes two vertex portions 101 adjacent to each other along the longitudinal extending direction of the first conductive line 110 or the second conductive line 120, and a portion located between the two vertex portions 101.
It can be appreciated that the sub-isolation unit 1001 has no disconnection portion D0, so that under the condition of meeting the electrical isolation performance of the virtual routing area 100, the situation that the virtual routing area 100 is provided with too many disconnection portions D0 is further reduced, which is further beneficial to improving the color difference problem, especially the problem of channel marks, between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10.
In some embodiments, at most one of the breaking portions D0 is disposed on the same grid edge 102 in the virtual routing area 100.
It has been found that the presence of more isolated first conductive lines 110 or second conductive lines 120 is more likely to result in channel marks due to the fact that the breaks are too dense. Based on this, the present application is provided with at most one of the breaking portions D0 on the same grid edge 102, that is, only one breaking portion D0 is provided when one grid edge 102 is provided, so that the situation that a single isolated first conductive line 110 or second conductive line 120 occurs is avoided, which is beneficial to improving the color difference problem, especially the problem of channel mark, between the signal channel region 200 and the virtual trace region 100 of the conductive grid 10.
In some embodiments, at least two of the sub-partition units 1001 are spaced between two adjacent signal channel regions 200.
Since at least two sub-partition units 1001 are spaced between two adjacent signal channel regions 200, that is, the partition between two adjacent signal channel regions 200 passes through at least two layers of partitions, that is, two sub-partition units 1001, when any one sub-partition unit 1001 of the two sub-partition units 1001 and one signal channel region 200 are turned on due to abnormality, the signal channel region 200 and the other signal channel region 200 can be electrically isolated from each other, which is beneficial to improving the electrical isolation performance of the virtual routing region 100.
In some embodiments, each sub-partition unit 1001 has a dimension H1 along the longitudinal extension direction of the virtual routing area 100, and a distance H2 between two adjacent vertex portions 101 along the longitudinal extension direction of the virtual routing area 100 is equal to or greater than H1.
Alternatively, H2 is less than or equal to H1 is less than or equal to 1.5H 2. Illustratively, H1 is equal to H2, 1.1 x H2, 1.2 x H2, 1.3 x H2, 1.4 x H2, or 1.5 x H2.
Alternatively, H2+.h1+.n.h2, n depends on the actual design of the grid pattern, such as the grid pattern design shown in fig. 1, where the grid size in the F Longitudinal direction direction is greater than the grid size in the F Wide width of direction, n may be chosen to be 1.5, and further, if the grid size in the F Longitudinal direction direction in fig. 1 is less than or equal to the grid size in the F Wide width of direction, n may be chosen to be 2 or 2.5.
If H1 is less than or equal to about H2, H1 may be considered to be equal to H2, depending on process variations, etc.
As H1 is greater than or equal to H2, it can be understood that the distance between two adjacent breaking portions D0 is larger along the longitudinal extension direction of the virtual routing area 100, which is favorable for reducing the arrangement density of the breaking portions D0, further reducing the situation that the virtual routing area 100 is densely broken by a plurality of breaking portions D0, and further being favorable for improving the chromatic aberration problem, particularly the problem of channel marks, between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100.
In some embodiments, as shown in fig. 1-4, the sub-partition unit 1001 includes at least one grid complete side 102a, where the grid complete side 102a is the grid complete side 102 located in the virtual routing area 100.
The partial sub-partition units 1001 may include at least one grid complete side 102a, or any sub-partition units 1001 may include at least one grid complete side 102a.
It can be understood that the sub-partition unit 1001 includes at least one grid complete edge 102a and two vertex portions 101 at two ends thereof, so that the virtual trace area 100 is not densely broken by the plurality of breaking portions D0, which is beneficial to improving the color difference problem, especially the problem of the channel mark, between the signal channel area 200 and the virtual trace area 100 of the conductive grid 10.
In some embodiments, at least two vertex portions 101 of each sub-partition unit 1001 are disposed at intervals along the longitudinal extension direction of the virtual routing area 100.
The sub-partition unit 1001 may be provided with two vertex portions 101, and the two vertex portions 101 may be arranged at intervals along the longitudinal extension direction of the virtual routing area 100, or the sub-partition unit 1001 may be provided with three vertex portions 101, wherein the two vertex portions 101 may be arranged at intervals along the longitudinal extension direction of the virtual routing area 100. Of course, four or more vertex portions 101 may be provided on the sub-partition unit 1001, and two vertex portions 101 may be disposed at intervals along the longitudinal extension direction of the virtual routing area 100.
In this way, at least two vertex parts 101 are arranged between two adjacent disconnection parts D0, so that the distance between two adjacent disconnection parts D0 is larger, which is favorable for reducing the arrangement density of the disconnection parts D0, further reducing the situation that the virtual wiring area 100 is densely interrupted by a plurality of disconnection parts D0, and further being favorable for improving the chromatic aberration problem, especially the problem of channel marks, between the signal channel area 200 and the virtual wiring area 100 of the conductive grid 10.
In some embodiments, the width of the virtual trace area 100 is a dimension of the virtual trace area 100 along a direction perpendicular to the lengthwise extending direction of the virtual trace area 100 and perpendicular to the thickness direction of the virtual trace area 100.
In fig. 1, the longitudinal extending direction of the virtual trace area 100 is denoted as F Longitudinal direction, and the width direction of the virtual trace area 100 is denoted as F Wide width of.
Alternatively, the breaking portion D0 is disposed to extend lengthwise from one end to the other end in the width direction of the virtual trace area 100.
In general, the smaller the width of the virtual wire area 100, the fewer paths the virtual wire area 100 can pass through, that is, the smaller the redundancy of the virtual wire area 100, at this time, under the condition that the electrical isolation performance of the virtual wire area 100 is met, fewer breaking portions D0 may be formed on the virtual wire area 100, for example, the dimension of the sub-isolating unit 1001 along the lengthwise extending direction of the virtual wire area 100 is set to be larger, which is further beneficial to forming fewer breaking portions D0 on the virtual wire area 100, so as to improve the color difference problem, especially the problem of the channel mark, between the signal channel area 200 of the conductive grid 10 and the virtual wire area 100 while the electrical isolation performance of the virtual wire area 100 is met.
As shown in fig. 1, in some embodiments, the plurality of breaking portions D0 are arranged to form a plurality of first breaking portion groups D1 disposed along the longitudinal extending direction of the virtual wire area 100, and a plurality of second breaking portion groups D2, each second breaking portion group D2 is located between two adjacent first breaking portion groups D1, and the breaking portions D0 of each first breaking portion group D1 are disposed at intervals along a direction perpendicular to the longitudinal extending direction of the virtual wire area 100 and perpendicular to the thickness direction of the virtual wire area 100. The breaking portions D0 of each second breaking portion set D2 are disposed along the longitudinal extending direction of the virtual routing area 100.
In this embodiment, along the longitudinal extending direction of the virtual routing area 100, the distance between two adjacent vertex portions 101 is H2, and the distance between adjacent breaking portions D0 in the adjacent first breaking portion group D1 is greater than or equal to H2.
In this embodiment, the redundancy of the virtual routing area 100 is greater than or equal to 3.
Fig. 1 shows an example of redundancy of 6 of the virtual routing area 100, and in the embodiment shown in fig. 1, each first disconnection group D1 includes six disconnection portions D0, which can be correspondingly understood in combination with the position marks B corresponding to the plurality of disconnection portions D0 of the first disconnection group D1. The second breaking group D2 includes one breaking portion D0, and similarly, the corresponding understanding can be performed in combination with the position mark B corresponding to the breaking portion D0 of the second breaking group D2.
Since the distance between the adjacent breaking portions D0 in the adjacent first breaking portion groups D1 is greater than or equal to H2, the first breaking portion groups D1 are distributed along the width direction of the virtual routing area 100, the distance between the adjacent two first breaking portion groups D1 is greater, and the number of breaking portions D0 in the second breaking portion groups D2 between the adjacent two first breaking portion groups D1 is smaller, the situation that a plurality of breaking portions D0 are densely distributed on the virtual routing area 100 can be reduced, and further, the color difference problem, particularly the channel mark problem, between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10 can be improved.
In this embodiment, at least one grid edge 102 is spaced between adjacent first break groups D1.
Because the distance between the adjacent first disconnection groups D1 is larger, the dispersion degree of the plurality of first disconnection groups D1 on the virtual routing area 100 can be improved, the situation that a plurality of disconnection parts D0 are densely arranged on the virtual routing area 100 can be reduced, and the color difference problem, particularly the channel mark problem, between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10 can be improved.
In some embodiments, the plurality of breaking portions D0 of the same first breaking portion group D1 are symmetrically arranged with respect to the first symmetry center line L1, and the breaking portions D0 of the second breaking portion group D2 are arranged along the first symmetry center line L1. The second breaking group D2 may be offset by a point with respect to the first symmetry center line L1 according to the actual situation.
In other embodiments, two adjacent second break groups D2 are arranged offset along a direction perpendicular to the longitudinal extension direction of the virtual trace area 100 and perpendicular to the thickness direction of the virtual trace area 100.
In this way, to a certain extent, the regularity of the arrangement of the plurality of disconnection portions D0 on the virtual routing area 100, that is, the disorder of the appearance, can be reduced, so as to reduce the obvious degree of the disconnection portions D0, and further facilitate improving the color difference problem, especially the problem of the channel mark, between the signal channel area 200 of the conductive mesh 10 and the virtual routing area 100.
In the present embodiment, the plurality of breaking portions D0 of the same first breaking portion set D1 are symmetrically disposed with respect to the first symmetry center line L1, and two adjacent second breaking portion sets D2 are located at two opposite sides of the first symmetry center line L1 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.
Of course, the present application is not limited thereto, and in other embodiments, the second breaking portion set D2 may be symmetrically disposed with the first symmetry center line L1 as a reference object.
In this way, the plurality of breaking portions D0 can be arranged regularly, so as to improve the color difference problem, especially the problem of channel mark, between the signal channel region 200 and the virtual trace region 100 of the conductive mesh 10. As shown in fig. 2, in other embodiments, a plurality of breaking portions D0 are arranged to form a plurality of third breaking portion groups D3 and a plurality of fourth breaking portion groups D4, the third breaking portion groups D3 and the fourth breaking portion groups D4 are alternately arranged along the longitudinal extending direction of the virtual routing area 100, the breaking portions D0 of the third breaking portion groups D3 are alternately arranged along the first direction F1, the breaking portions D0 of the fourth breaking portion groups D4 are alternately arranged along the second direction F2, and the first direction F1 is disposed at an angle to the second direction F2 and is disposed at an angle to the longitudinal extending direction of the virtual routing area 100. The first direction F1 may be parallel to the lengthwise extending direction of the first conductive line 110, and the second direction F2 may be parallel to the lengthwise extending direction of the second conductive line 120. Alternatively, the first direction F1 is parallel to the longitudinal extending direction of the second conductive line 120, and the second direction F2 is parallel to the longitudinal extending direction of the first conductive line 110.
In the present embodiment, the redundancy of the virtual routing area 100 is equal to 2.
Because the third disconnecting portion group D3 and the fourth disconnecting portion group D4 are alternately arranged, the disconnecting portions D0 of the third disconnecting portion group D3 change the one-time interval arrangement direction relative to the disconnecting portions D0 in the adjacent fourth disconnecting portion group D4, which is favorable for a plurality of disconnecting portions D0 to be relatively dispersedly arranged on the virtual routing area 100, and is further favorable for improving the chromatic aberration problem, particularly the channel mark problem, between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10.
In this embodiment, the breaking portions D0 of the third breaking portion group D3 may be disposed on the adjacent first conductive lines 110, the breaking portions D0 of the fourth breaking portion group D4 may be disposed on the adjacent second conductive lines 120, for example, the two breaking portions D0 of the third breaking portion group D3 may be disposed on the adjacent two first conductive lines 110, the two breaking portions D0 of the fourth breaking portion group D4 may be disposed on the adjacent two second conductive lines 120, the breaking portions D0 of the third breaking portion group D3 may be disposed on the adjacent second conductive lines 120, and the breaking portions D0 of the fourth breaking portion group D4 may be disposed on the adjacent first conductive lines 110, for example, the two breaking portions D0 of the third breaking portion group D3 may be disposed on the adjacent two second conductive lines 120, and the two breaking portions D0 of the fourth breaking portion group D4 may be disposed on the adjacent two first conductive lines 110.
Specifically, in the embodiment shown in fig. 2, the first direction F1 is parallel to the lengthwise extending direction of the second conductive line 120, and the second direction F2 is parallel to the lengthwise extending direction of the first conductive line 110. The two disconnecting portions D0 of the third disconnecting portion group D3 are respectively disposed on the two adjacent first conductive wires 110, and the two disconnecting portions D0 of the fourth disconnecting portion group D4 are respectively disposed on the two adjacent second conductive wires 120
In particular, in the embodiment shown in fig. 2, the sub-partition units 1001 have a substantially triangular structure, and the whole body formed by two adjacent sub-partition units 1001 has a substantially parallelogram structure.
In this way, the two adjacent sub-isolation units 1001 may be disconnected by the two disconnection portions D0 of the same third disconnection portion group D3, or disconnected by the two disconnection portions D0 of the same fourth disconnection portion group D4, so that at least two sub-isolation units 1001 are spaced between the two adjacent signal channel regions 200, which is beneficial to improving the electrical isolation performance of the virtual routing region 100, that is, when any one sub-isolation unit 1001 of the two sub-isolation units 1001 and one signal channel region 200 are conducted due to abnormality, the signal channel region 200 and the other signal channel region 200 can also be kept electrically isolated from each other.
As shown in fig. 4, in still other embodiments, the plurality of breaking portions D0 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100, and two vertex portions 101 or a grid edge 102 are spaced between any two adjacent breaking portions D0.
In the present embodiment, the redundancy of the virtual routing area 100 is equal to 1.
That is, along the longitudinal extending direction of the virtual trace area 100, a breaking portion D0 is disposed at every other complete grid edge 102a, and since the redundancy of the virtual trace area 100 is smaller, two vertex portions 101 or a grid edge 102 are disposed between any two adjacent breaking portions D0, which is beneficial to reducing the arrangement density of the breaking portions D0, so as to improve the color difference problem, especially the channel mark problem, between the signal channel area 200 of the conductive grid 10 and the virtual trace area 100 while meeting the electrical isolation performance of the virtual trace area 100.
In still other embodiments, as shown in fig. 3 and 5, the virtual routing area 100 includes a first type area 100a and a second type area 100b, where the redundancy of the first type area 100a and the second type area 100b is different, and the transverse dotted line dividing the virtual routing area in fig. 3 and 5 represents the boundary between the first type area 100a and the second type area 100 b.
Because the design of the conductive grid 10 has random amounts, the grid random can be divided into random intervals and random vertexes, distances between adjacent first conductive wires and between adjacent second conductive wires in the random intervals are different, random distribution exists in the allowed range of the vertexes of the first conductive wires and the second conductive wires in the random vertexes, the occurrence of different regional redundancy can be caused, namely, the redundancy of different areas of the virtual routing area 100 is different, so that the arrangement of the disconnection parts D0 in the corresponding areas can be set according to the redundancy of the different areas, and in this way, the arrangement of a proper number of disconnection parts D0 on the first type area 100a and the second type area 100b of the virtual routing area 100 is facilitated, under the condition that the electric partition performance of the virtual routing area 100 is met, the situation that the excessive disconnection parts D0 are arranged on the virtual routing area 100 is reduced is facilitated, and the problem of chromatic aberration, particularly the problem of channel marks, between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10 can be better improved.
As shown in fig. 3, in some embodiments, the redundancy of the first type of region 100a is 2 and the redundancy of the second type of region 100b is 1.
The plurality of breaking parts D0 are arranged to form a plurality of fifth breaking part groups D5, a plurality of sixth breaking part groups D6 and a plurality of seventh breaking part groups D7, wherein the fifth breaking part groups D5 and the sixth breaking part groups D6 are alternately arranged along the longitudinal extension direction of the virtual routing area 100 in the first type area 100a, and the breaking parts D0 of the seventh breaking part group D7 are arranged on the grid complete edge 102a in the second type area 100 b.
The fifth disconnection group D5 and the adjacent sixth disconnection group D6 are disposed at intervals in a direction perpendicular to the lengthwise extending direction of the virtual wiring region 100 and perpendicular to the thickness direction of the virtual wiring region 100. It will be appreciated that the plurality of fifth disconnect groups D5 and the plurality of sixth disconnect groups D6 are generally in an S-shaped arrangement (as can be appreciated from the arrangement of disconnects D0 shown in fig. 2).
At least two breaking portions D0 of the fifth breaking portion group D5 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100, at least two breaking portions D0 of the sixth breaking portion group D6 are arranged at intervals along the longitudinal extension direction of the virtual routing area 100, the number of breaking portions D0 of the fifth breaking portion group D5 and the sixth breaking portion group D6 is two, and the number of breaking portions D0 of the seventh breaking portion group D7 is at least four.
Since the breaking portions D0 of the seventh breaking portion group D7 are disposed on the grid complete side 102a, the occurrence of isolated first conductive lines 110 or second conductive lines 120 can be reduced, and the occurrence of dense breaking of the virtual routing area 100 can also be reduced. In this way, under the condition that the electrical isolation performance of the virtual routing area 100 is met, the situation that the virtual routing area 100 is provided with too many disconnecting parts D0 is more facilitated to be reduced, and further the chromatic aberration problem, particularly the problem of channel marks, between the signal channel area 200 of the conductive grid 10 and the virtual routing area 100 can be better improved.
As shown in fig. 5 and 6, in other embodiments, the redundancy of the first type region 100a is 1, the redundancy of the second type region 100b is 0, the breaking portion D0 is disposed on the grid complete side 102a in the first type region 100a, and in the case that at least two breaking portions D0 are disposed in the first type region 100a, two vertex portions 101 or a grid side 102 are spaced between two adjacent breaking portions D0.
On the one hand, the breaking portion D0 is disposed on the grid complete side 102a in the first type region 100a, so that the situation that the virtual routing area 100 is densely broken in the first type region 100a can be reduced, and it can be understood that the breaking portion D0 is not disposed in the second type region 100b, because the redundancy of the second type region 100b is 0, that is, the grid side 102 does not exist in the second type region 100b, and a closed conducting line cannot be formed in the second type region 100b, so that the breaking portion D0 does not need to be disposed in the second type region 100b, on the other hand, in the case that at least two vertex portions 101 are disposed in the first type region 100a, two vertex portions 101 or one grid side 102 are disposed between two adjacent breaking portions D0, so that the breaking portion D0 is relatively distributed in the first type region 100a, so that the number of breaking portions D0 can be reduced while the electrical breaking performance of the virtual routing area 100 is satisfied, and further the color difference problem, particularly the color difference problem between the signal channel area 200 and the virtual routing area 100 of the conductive grid 10 can be improved.
An embodiment of the present application provides a touch sensor, which at least includes a first conductive mesh 10a and a second conductive mesh 10b that are stacked and spaced apart from each other, and at least one of the first conductive mesh 10a and the second conductive mesh 10b is the conductive mesh 10 described above. The disconnection portion D0 of one of the first conductive mesh 10a and the second conductive mesh 10b, which is provided with the disconnection portion D0, is provided at the overlapping intersection of the conductive wires in the first conductive mesh 10a and the second conductive mesh 10 b.
As shown in fig. 7, a longitudinal extending direction of the break portion D0 provided with one of the break portions D0 of the first conductive mesh 10a and the second conductive mesh 10b is provided so as to intersect with a portion of the other of the first conductive mesh 10a and the second conductive mesh 10b corresponding to the break portion D0.
Specifically, in the embodiment shown in fig. 7, the first conductive mesh 10a is located on the upper layer of the second conductive mesh 10b, a plurality of breaking portions D0 are provided on the first conductive mesh 10a, and the breaking portions D0 on the first conductive mesh 10a and the portions of the second conductive mesh 10b corresponding to the breaking portions D0 are disposed to intersect. In this way, the apparent degree of the disconnection D0 in appearance is further reduced, thereby improving the problem of large chromatic aberration between the dummy wiring section 100 and the signal channel section 200.
Of course, the present application is not limited to this, and the first conductive mesh 10a may be positioned under the second conductive mesh 10b, and a plurality of the disconnection portions D0 may be provided on each of the first conductive mesh 10a and the second conductive mesh 10b, so long as the disconnection portion D0 on the first conductive mesh 10a and the portion of the second conductive mesh 10b corresponding to the disconnection portion D0 intersect each other, and the disconnection portion D0 on the second conductive mesh 10b and the portion of the first conductive mesh 10a corresponding to the disconnection portion D0 intersect each other.
In this way, the disconnection portion D0 on the first conductive mesh 10a may be laid out with reference to the layout of the second conductive mesh 10b, the disconnection portion D0 on the second conductive mesh 10b may be laid out with reference to the layout of the first conductive mesh 10a, and the same series of interruption modes may be adopted for both the first conductive mesh 10a and the second conductive mesh 10b, so that the complexity of the system may be reduced.
The embodiment of the application also discloses a touch display, which comprises the touch sensor and a display unit, wherein the touch sensor is arranged on one side of the display unit, and the touch display further comprises a packaging layer covered on the display unit, wherein the touch sensor is arranged on one side of the packaging layer far away from the display unit so as to realize on-screen touch, and the touch sensor is also arranged on one side of the packaging layer close to the display unit so as to realize on-screen touch.
