Figure 2 A schematic diagram of the local structure of a grid electrode in an embodiment of the present application is shown. Figure 3 Shows Figure 1 An enlarged schematic diagram of point A.

[0050] See also Figure 1-Figure 3According to the first aspect of the present application, an embodiment of the present application provides a grid break portion D1, a plurality of first conductive wires 110 and a plurality of second conductive wires 120 are cross-connected to form a closed grid structure, and in some of the first conductive wires 110 and some of the second conductive wires 120, the extension lines of the first conductive wires 110 and the second conductive wires 120 intersect at a virtual vertex portion, and the grid break portion D1 is arranged at the virtual vertex portion, and the grid break portion D1 includes two third conductive wires 130 arranged at intervals, and the two third conductive wires 130 are located on both sides of the virtual vertex portion, wherein the two ends of each third conductive wire 130 are respectively connected to the first conductive wire 110 and the adjacent second conductive wire 120, and are pre-intersected at one end of the virtual vertex portion.

[0051] It can be understood that the grid break portion D1 is used to disconnect two adjacent closed grid structures. If the grid break portion D1 is applied to the grid electrode 100, the grid break portion D1 on the grid electrode 100 can be used to reduce the color difference between the area where the grid electrode 100 is located and the area between the two adjacent grid electrodes 100, thereby improving the color difference problem; in addition, compared with the break formed by direct cutting, the grid break portion D1 of the present application is formed between two adjacent closed grid structures, and does not affect the connectivity of the closed grid structure adjacent to the grid break portion D1. In this way, the impact on the internal connectivity of the grid electrode 100 can be greatly reduced, thereby reducing the impact of the break formed by direct cutting on the electrical properties such as the overall channel impedance.

[0052] In some embodiments, the first conductive line 110 and the second conductive line 120 connected to the same third conductive line 130 are arranged at an angle ɑ, where 60°≤ɑ≤130°.

[0053] Illustratively, α is 60°, 70°, 80°, 90°, 100°, 110°, 120°, or 130°.

[0054] Set ɑ within a suitable range, such as 60°≤ɑ≤130°. This can effectively avoid moiré patterns.

[0055] In some embodiments, the distance between two third conductive lines 130 in the same mesh break portion D1 is D, and 3 μm≤D≤30 μm.

[0056] Illustratively, D is 3 μm, 6 μm, 9 μm, 12 μm, 15 μm, 18 μm, 21 μm, 24 μm, 27 μm or 30 μm.

[0057] The grid electrode 100 is arranged along the first direction F 1 Extended, and the first direction F 1 With the second direction F 2Taking the example of being perpendicular to each other, the distance between the two third conductive lines 130 in the same grid break portion D1 is the distance between the two third conductive lines 130 in the same grid break portion D1 along the second direction F 2 spacing.

[0058] If the spacing between the two third conductive lines 130 of the same grid break portion D1 is too large, it will occupy too much area of ​​the grid electrode 100, which is not conducive to improving the channel mark, that is, improving a color difference problem; if the spacing between the two third conductive lines 130 of the same grid break portion D1 is too small, it will increase the difficulty of manufacturing the process; for this reason, it is necessary to set D within an appropriate range, such as setting it to: 3μm≤D≤30μm, so that the problem of channel marks can be effectively improved while reducing the difficulty of manufacturing the grid electrode 100.

[0059] According to the second aspect of the present application, an embodiment of the present application provides a grid electrode 100, on which a plurality of closed grid structures arranged in rows and columns and a plurality of grid break portions D1 of any of the above-mentioned embodiments are provided, a plurality of first conductive wires 110 and a plurality of second conductive wires 120 are cross-connected to form a plurality of closed grid structures, and all the grid break portions D1 on the grid electrode 100 divide the grid electrode 100 into a plurality of sub-electrodes 1001 that are parallel to each other and conductive to each other or staggered and conductive to each other.

[0060] For example, a plurality of closed grid structures are arranged along a first direction F 1 Arranged in a row, along the second direction F 2 Arranged in rows, first direction F 1 With the second direction F 2 The two grid electrodes 100 intersect with each other and are perpendicular to the thickness direction of the grid electrode 100 .

[0061] Optionally, the first direction F 1 With the second direction F 2 Perpendicular to each other.

[0062] The multiple closed grid structures include multiple first closed grid structures 101 and multiple second closed grid structures 102 , and the grid break portion D1 is formed between two adjacent second closed grid structures 102 .

[0063] The first conductive lines 110 and the second conductive lines 120 intersect each other at a vertex portion 103 . The first closed grid structure 101 is provided with four vertex portions 103 , and the second closed grid structure 102 is provided with two or three vertex portions 103 .

[0064] The cross-sectional shape of the first closed grid structure 101 can be a polygon such as a triangle, quadrilateral, pentagon or hexagon. For example, the cross-sectional shape of the first closed grid structure 101 is a rhombus. The cross-sectional shape of the first closed grid structure 101 can also be an arc ring or other shapes.

[0065] All the grid break portions D1 on the grid electrode 100 divide the grid electrode 100 into a plurality of sub-electrodes 1001 that are electrically connected to each other. The plurality of sub-electrodes 1001 may be arranged in parallel or staggered with each other.

[0066] It can be that the grid electrode 100 is arranged along the first direction F 1 The sub-electrode 1001 is extended along the first direction F 1 Alternatively, the grid electrode 100 is arranged along the second direction F 2 The sub-electrode 1001 is extended along the second direction F 2 Extended setting; no specific limitation is given here.

[0067] It can be understood that the sub-electrode 1001 is provided with a plurality of closed grid structures arranged along the longitudinal extension direction of the grid electrode 100, and the plurality of closed grid structures on the sub-electrode 1001 include a first closed grid structure 101 and / or a second closed grid structure 102. It can be that the sub-electrode 1001 is provided with a plurality of first closed grid structures 101, or it can be that the sub-electrode 1001 is provided with a plurality of second closed grid structures 102; it can also be that the sub-electrode 1001 is provided with a first closed grid structure 101 and a second closed grid structure 102, and no specific limitation is made here.

[0068] Since all the grid break portions D1 on the grid electrode 100 divide the grid electrode 100 into mutually conductive sub-electrodes 1001, in two adjacent sub-electrodes 1001, the grid break portions D1 on the grid electrode 100 are used to disconnect two adjacent second closed grid structures 102. If the grid electrode 100 is applied to the touch layer 10, the break portion D1 on the touch layer 10 located between the two adjacent grid electrodes 100 and used to disconnect the two adjacent grid electrodes 100 (combined with Figure 1 and Figure 4It is understood that the fracture is the disconnection portion D2 described below), and the multiple grid fracture portions D1 on the grid electrode 100 can better reduce the color difference between the area where the grid electrode 100 is located on the touch layer 10 and the area between two adjacent grid electrodes 100, and then the multiple grid fracture portions D1 can be used to improve the color difference problem of the touch layer 10, and the grid electrode 100 can also be divided into multiple sub-electrodes 1001 electrically connected to each other. In addition, compared with the fracture formed by direct cutting, the grid fracture portion D1 of the present application is formed between two adjacent second closed grid structures 102, which does not affect the connectivity of the second closed grid structure 102. In this way, the impact on the internal connectivity of the grid electrode 100 can be greatly reduced, and the impact of the fracture formed by direct cutting on the overall channel impedance and other electrical properties can be reduced.

[0069] In some embodiments, the grid break portion D1 is extended along the longitudinal extension direction of the grid electrode 100 .

[0070] It can be understood that the grid break portion D1 is formed between two adjacent sub-electrodes 1001. Preferably, the break direction of the grid break portion D1 (ie, the direction of the third wire) is parallel to the longitudinal extension direction of the grid electrode 100.

[0071] In this way, the signal transmitted on the grid electrode 100 can be well extended from one end of the grid electrode 100 to the other end along the longitudinal extension direction of the grid electrode 100, reducing the signal turning and further reducing the impact on electrical properties such as the overall channel impedance.

[0072] In some embodiments, the first conductive line 110 and the second conductive line 120 intersecting each other intersect at a vertex 103 . The sub-electrodes 1001 are extended along the longitudinal extension direction of the grid electrode 100 , and any two adjacent sub-electrodes 1001 are connected through at least one vertex 103 .

[0073] In this way, while using multiple grid break portions D1 to improve the color difference problem of the touch layer 10, the grid electrode 100 can also be divided into multiple sub-electrodes 1001 that are electrically connected to each other, which can reduce the impact on the electrical properties such as the overall channel impedance of the grid electrode 100, and can also improve the redundancy of the grid electrode 100, reducing the probability of some sub-electrodes 1001 being unable to pass through adjacent sub-electrodes 1001, thereby reducing the occurrence of touch failure.

[0074] In some embodiments, the sub-electrodes 1001 are extended along the longitudinal extension direction of the grid electrode 100 , and in two adjacent sub-electrodes 1001 , two adjacent grid break portions D1 are staggered along the longitudinal extension direction of the grid electrode 100 .

[0075] With such an arrangement, two adjacent sub-electrodes 1001 can be connected via at least one vertex portion 103, and while the color difference problem of the touch layer 10 can be improved by utilizing the plurality of grid break portions D1, the grid electrode 100 can also be divided into a plurality of sub-electrodes 1001 electrically connected to each other, thereby reducing the impact on the electrical properties such as the overall channel impedance of the grid electrode 100 and improving the redundancy of the grid electrode 100.

[0076] In some embodiments, the multiple sub-electrodes 1001 include two edge region sub-electrodes 10011 and multiple middle region sub-electrodes 10012, the multiple middle region sub-electrodes 10012 are located between the two edge region sub-electrodes 10011, and the grid break portion D1 is arranged on the multiple middle region sub-electrodes 10012, or between the middle region sub-electrode 10012 and the adjacent edge region sub-electrode 10011.

[0077] The middle region sub-electrode 10012 refers to a sub-electrode 1001 located between two edge region sub-electrodes 10011 among the plurality of sub-electrodes 1001 ; the two edge region sub-electrodes 10011 refer to two sub-electrodes 1001 located on both sides of the plurality of middle region sub-electrodes 10012 .

[0078] The grid electrode 100 and the sub-electrode 1001 are both along the first direction F 1 Extended, and the first direction F 1 With the second direction F 2 Taking the example of being perpendicular to each other, the two edge region sub-electrodes 10011 are respectively along the second direction F 2 Located on both sides of the plurality of middle region sub-electrodes 10012. Preferably, the channel redundancy of all middle region sub-electrodes 10012 is consistent, and the channel redundancy can be obtained by drawing a measurement line in a direction perpendicular to the channel direction and calculating the minimum number of grid lines intersecting the measurement line and terminating at two grid vertices.

[0079] In this way, the redundancy of the sub-electrodes 10011 in the edge region of the grid electrode 100 can be improved, thereby reducing the probability of poor touch control of the grid electrode 100 .

[0080] In some embodiments, the longitudinal extension direction of the first conductive line 110 and the longitudinal extension direction of the second conductive line 120 intersect each other, intersect the longitudinal extension direction of the grid electrode 100 , and are perpendicular to the thickness direction of the grid electrode 100 .

[0081] In this way, the first conductive line 110 and the second conductive line 120 can intersect to form a first closed grid structure 101 with a diamond cross-section, and the multiple first closed grid structures 101 arranged along the longitudinal extension direction of the grid electrode 100 can constitute the sub-electrode 1001 of the grid electrode 100, so that in the process of the signal moving from one end of the grid electrode 100 to the other end along the longitudinal extension direction of the grid electrode 100, it can pass through the first conductive line 110 and / or the second conductive line 120 of the sub-electrode 1001, thereby improving the redundancy of the grid electrode 100.

[0082] In some embodiments, the first conductive line 110 and the second conductive line 120 intersecting each other may intersect at a vertex portion 103 , and at least one vertex portion 103 is provided between two adjacent grid break portions D1 along the longitudinal extension direction of the first conductive line 110 .

[0083] Alternatively, the first conductive line 110 and the second conductive line 120 intersecting each other intersect at a vertex portion 103 , and at least one vertex portion 103 is provided between two adjacent mesh break portions D1 along the longitudinal extension direction of the second conductive line 120 .

[0084] It is also possible that the first conductive line 110 and the second conductive line 120 intersecting each other intersect at a vertex 103, at least one vertex 103 is provided between two adjacent grid break portions D1 along the longitudinal extension direction of the first conductive line 110, and at least one vertex 103 is provided between two adjacent grid break portions D1 along the longitudinal extension direction of the second conductive line 120.

[0085] In this way, it is possible to avoid the situation where two grid break portions D1 are arranged adjacent to each other in the closed grid structure (the second closed grid structure 102) adjacent to the grid break portion D1. In other words, if two grid break portions D1 are provided on the closed grid structure (the second closed grid structure 102) adjacent to the grid break portion D1, the two grid break portions D1 are arranged relative to each other, thereby reducing the situation where two adjacent sub-electrodes 1001 cannot be electrically connected to each other, thereby improving the redundancy of the grid electrode 100, reducing the probability of poor touch of the grid electrode 100, and reducing the influence of the grid break portion D1 on the electrical properties such as the overall channel impedance.

[0086] In some embodiments, the first conductive lines 110 and the second conductive lines 120 intersecting each other intersect at a vertex 103, and all the grid break portions D1 on the grid electrode 100 are arranged in multiple rows, and at least one vertex 103 is provided between at least two adjacent grid break portions D1 in the same row. The row direction of the grid break portions D1 is parallel to the longitudinal extension direction of the grid electrode 100.

[0087] In this way, two adjacent rows of sub-electrodes 1001 can be connected to each other through the vertex portion 103 located between two adjacent grid break portions D1 and thus be conductive, which is beneficial to improving the redundancy of the grid electrode 100 and avoiding poor touch control.

[0088] In other embodiments, all the grid break portions D1 on the grid electrode 100 are arranged in multiple columns, and at least one vertex portion 103 is provided between at least two adjacent grid break portions D1 in the same column. The column direction of the grid break portions D1 is perpendicular to the longitudinal extension direction of the grid electrode 100 and perpendicular to the thickness direction of the grid electrode 100.

[0089] Two adjacent rows of sub-electrodes 1001 can be connected to each other and conducted through the vertex portion 103 located between two adjacent grid break portions D1, so that at least one position in each column of the grid electrode 100 is not provided with a grid break portion D1, which is beneficial to improving the redundancy of the grid electrode 100 and also beneficial to avoiding poor touch.

[0090] In some other embodiments, all the grid break portions D1 on the grid electrode 100 are arranged into multiple rows, and at least one vertex portion 103 is provided between at least one adjacent two grid break portions D1 in the same row. All the grid break portions D1 on the grid electrode 100 are arranged into multiple columns, and at least one vertex portion 103 is provided between at least one adjacent two grid break portions D1 in the same column. The row direction of the grid break portions D1 is parallel to the longitudinal extension direction of the grid electrode 100, and the column direction of the grid break portions D1 is perpendicular to the longitudinal extension direction of the grid electrode 100 and perpendicular to the thickness direction of the grid electrode 100.

[0091] That is to say, all the mesh cutouts D1 on the mesh electrode 100 are arranged in rows and columns.

[0092] In this way, the redundancy of the grid electrode 100 can be improved, and poor touch control can be avoided.

[0093] In some embodiments, the number of mesh cutouts D1 in the same column is greater than or equal to half the number of rows of mesh cutouts D1 .

[0094] In this way, on the one hand, the number of grid break portions D1 can be increased, so that the arrangement density of the grid break portions D1 of the grid electrode 100 (the arrangement density of the grid break portions D1 of the grid electrode 100 is the number of grid break portions D1 per unit area of ​​the grid electrode 100) can be close to the arrangement density of the disconnected portions D2 of the grid electrode 100, which is beneficial to better improve the color difference problem; on the other hand, two adjacent rows of sub-electrodes 1001 can be connected to each other through the vertex portion 103 located between two adjacent grid break portions D1, so that the redundancy of the grid electrode 100 is at least 2, which is also beneficial to avoid poor touch.

[0095] In some embodiments, the arrangement density of the grid break portions D1 of the grid electrode 100 is equal to the break arrangement density of the area between two adjacent grid electrodes, or the difference between the arrangement density of the grid break portions D1 of the grid electrode 100 and the break arrangement density of the area between two adjacent grid electrodes is within an appearance threshold range, which is determined by the color difference between the grid electrode and the area between two adjacent grid electrodes.

[0096] In some embodiments, Figure 6-Figure 8 and Figure 9-14 As shown, the orthographic projection pattern of the grid electrode 100 in the target plane is constructed as a symmetrical pattern, the symmetrical pattern has a central axis Z parallel to the longitudinal extension direction of the grid electrode 100, and the target plane is perpendicular to the thickness direction of the grid electrode 100. All grid fracture portions D1 on the grid electrode 100 are symmetrically arranged with the central axis Z as a reference object.

[0097] like Figure 6-Figure 17 As shown in FIG. 1 , the position mark D0 of the grid break portion D1 on the grid electrode 100 is given, and the position mark D0 corresponds to the grid break portion D1 one by one. Figure 5 The position shown is marked D0, combined with Figure 3 The structural diagram of the mesh fracture portion D1 is shown in FIG. Figure 5 In the illustrated embodiment, a corresponding plurality of grid break portions D1 are arranged on the grid electrode 100 .

[0098] For example, according to Fig.12 The position shown is marked D0, combined with Figure 3 The structural diagram of the mesh fracture portion D1 is shown in FIG. Fig.12 In the embodiment shown, a plurality of corresponding grid break portions D1 are arranged on the grid electrode 100. Fig.12 The specific structure of the multiple grid break portions D1 on the grid electrode 100 in the embodiment shown is as follows Figure 2 shown.

[0099] In this way, all the grid break portions D1 on the grid electrode 100 can be arranged more evenly, thereby making the potential distribution in the touch channel region where the grid electrode 100 is located more uniform, thereby helping to reduce the impact on electrical properties such as overall channel impedance.

[0100] Of course, the present application is not limited thereto, and all the grid break portions D1 on the grid electrode 100 may also be arranged roughly symmetrically with the central axis Z as a reference object (eg Fig. 9 as shown).

[0101] In some embodiments, the orthographic projection pattern of the grid electrode 100 in the target plane is constructed as a symmetrical pattern, the symmetrical pattern has a central axis Z parallel to the longitudinal extension direction of the grid electrode 100, and the target plane is perpendicular to the thickness direction of the grid electrode 100. All grid fracture portions D1 on the grid electrode 100 are arranged to form a plurality of rows of grid fracture portion groups, and two rows of grid fracture portion groups located on both sides of the central axis Z and adjacent to each other are staggered along the longitudinal extension direction of the grid electrode 100.

[0102] In this way, all the grid break portions D1 on the grid electrode 100 can be arranged roughly evenly, thereby making the potential distribution in the touch channel area where the grid electrode 100 is located more uniform, thereby helping to reduce the impact on electrical properties such as overall channel impedance.

[0103] In some embodiments, all the grid break portions D1 on the grid electrode 100 are arranged to form a plurality of repeating units, and a center line connecting the plurality of grid break portions D1 in each repeating unit forms a virtual polygon.

[0104] Virtual polygons can be virtual triangles (can be combined with Fig.10 , 11 As shown), virtual quadrilateral (can be combined with Fig.13 , Fig.14 or Fig.15 as shown), virtual pentagon, virtual hexagon, virtual heptagon or virtual octagon (can be combined Fig.16 as shown) etc.

[0105] In this way, all the grid break portions D1 on the grid electrode 100 can be arranged periodically, thereby making the potential distribution in the touch channel region where the grid electrode 100 is located more uniform, thereby helping to reduce the impact on electrical properties such as overall channel impedance.

[0106] In this embodiment, the orthographic projection pattern of the grid electrode 100 in the target plane is constructed as a symmetrical pattern, the symmetrical pattern has a central axis Z parallel to the longitudinal extension direction of the grid electrode 100, and the target plane is perpendicular to the thickness direction of the grid electrode 100. Multiple repeating units are symmetrically arranged with the central axis Z as a reference object.

[0107] In this way, all the grid break portions D1 on the grid electrode 100 can be symmetrically arranged on both sides of the central axis Z, thereby making the potential distribution in the touch channel area where the grid electrode 100 is located more uniform, thereby helping to reduce the impact on electrical properties such as overall channel impedance.

[0108] In this embodiment, the orthographic projection pattern of the grid electrode 100 in the target plane is constructed as a symmetrical pattern, the symmetrical pattern has a central axis Z parallel to the longitudinal extension direction of the grid electrode 100, and the target plane is perpendicular to the thickness direction of the grid electrode 100. A plurality of repeating units are arranged in a plurality of rows, and in two adjacent rows of repeating units, two adjacent repeating units are staggered along the longitudinal extension direction of the grid electrode 100.

[0109] In this way, the two repeating units located on both sides of the central axis Z and adjacent to each other are staggered along the longitudinal extension direction of the grid electrode 100, which is conducive to a more uniform distribution of multiple repeating units on the grid electrode 100, thereby making the potential distribution in the touch channel area where the grid electrode 100 is located more uniform, which is conducive to reducing the impact on electrical properties such as the overall channel impedance.

[0110] Of course, the present application is not limited thereto, and multiple repeating units may also be arranged according to other rules, for example, Fig.17 In two adjacent rows of repeating units, the two adjacent repeating units are symmetrically arranged, so that the potential distribution in the touch channel region where the grid electrode 100 is located can be more uniform, thereby helping to reduce the impact on electrical properties such as the overall channel impedance.

[0111] According to the third aspect of the present application, an embodiment of the present application provides a touch layer 10, comprising a plurality of grid electrodes 100 of any of the above embodiments, and a plurality of virtual routing areas 200, each virtual routing area 200 being located between two adjacent grid electrodes 100, and a plurality of disconnecting portions D2 being provided on the virtual routing area 200.

[0112] It can be understood that the plurality of disconnected portions D2 are used to prevent two adjacent grid electrodes 100 from being electrically connected to each other.

[0113] Since the grid electrode 100 is provided with a plurality of grid break portions D1 and the virtual wiring area 200 is provided with a plurality of disconnected portions D2, the color difference between the area where the grid electrode 100 is located and the area where the virtual wiring area 200 is located on the touch layer 10 can be further reduced, thereby improving the color difference problem and the channel mark problem.

[0114] In some embodiments, the number of grid break portions D1 per unit area of ​​the grid electrode 100 is a, and the number of disconnected portions D2 per unit area of ​​the virtual routing area 200 is b. Both a and b are positive integers greater than 1, and |ab|≤2.

[0115] It should be noted that a and b are obtained by rounding down.

[0116] It can be, a<b, ba≤2. It can also be, a>b, ab≤2.

[0117] Preferably, the unit area can generally be 0.5 cm 2 , 1cm 2 , 2cm 2 , 4cm 2 , 5cm 2 、8cm 2 , 10cm 2 、12cm 2 And so on, the number of grid fractures and disconnected parts per unit area can be calculated in this way, or it can be calculated based on the area of ​​the entire grid electrode, the virtual routing area and the corresponding number of grid fractures and disconnected parts, which is not specifically limited in this embodiment.

[0118] The number of grid break portions D1 per unit area of ​​the grid electrode 100 is the arrangement density of the grid break portions D1, and the number of disconnected portions D2 per unit area of ​​the virtual routing area 200 is the arrangement density of the disconnected portions D2. That is, the arrangement density of the grid break portions D1 is a, and the arrangement density of the disconnected portions D2 is b.

[0119] In this way, by reasonably designing the number of grid break portions D1, a can be made close to b, that is, the number of grid break portions D1 per unit area of ​​the grid electrode 100 can be made close to the number of disconnected portions D2 per unit area of ​​the virtual wiring area 200, thereby better reducing the color difference between the area where the grid electrode 100 is located and the area where the virtual wiring area 200 is located on the touch layer 10, thereby better improving the color difference problem and the channel mark problem.

[0120] In this embodiment, compared with no break on the touch electrode, the grid break portion D1 of the present application can control the impedance change rate of the grid electrode 100 of the present application within 20%. For example, compared with no break on the touch electrode, the grid break portion D1 of the present application can make the impedance change rate of the grid electrode 100 of the present application 10%.

[0121] An embodiment of the present application provides a display panel, comprising the touch layer 10 of any of the above embodiments.

[0122] The display panel includes the above-mentioned touch layer 10 , which can improve the color difference problem and channel mark problem of the touch layer 10 , thereby improving the display effect of the display panel.

[0123] Optionally, the display panel includes a first touch layer and a second touch layer which are stacked and spaced apart from each other, and at least one of the first touch layer and the second touch layer is the above-mentioned touch layer 10 .

[0124] Taking the case where both the first touch layer and the second touch layer are the above-mentioned touch layer 10 as an example, the grid electrode 100 of the first touch layer and the grid electrode 100 of the second touch layer are perpendicular to each other. In this way, the grid electrode 100 of the first touch layer can be used as an emitter, and the grid electrode 100 of the second touch layer can be used as a receiver, thereby forming mutual capacitive touch.

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.

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.
