[0053] This disclosure will now be described in more detail with reference to the following embodiments. It should be noted that the following description of some embodiments presented herein is for illustrative and descriptive purposes only. It is not exhaustive or limited to the precise forms disclosed.

[0054] This disclosure provides, in particular, a touch structure, a display panel, a display device, and a method of manufacturing the touch structure, which substantially eliminates one or more problems caused by the limitations and disadvantages of the prior art. In one aspect, the invention provides a touch structure. In some embodiments, the touch structure includes a plurality of first touch electrodes arranged in multiple rows and a plurality of second touch electrodes arranged in multiple columns. In some embodiments, the multiple rows of the plurality of first touch electrodes extend to a first edge of the touch structure. Each of the multiple rows includes a plurality of non-edge first electrode blocks and a first edge electrode block, the plurality of first edge electrode blocks being arranged along the first edge. Optionally, the plurality of non-edge first electrode blocks have the same shape; the first edge electrode block includes a first main edge portion and a first side edge portion, respectively, along the first edge. Optionally, each of the plurality of non-edge first electrode blocks includes a first main portion and a first side portion, respectively, along a first virtual line parallel to the first edge. Optionally, the boundaries of the first main portion and the first side portion are disconnected from each other along the first virtual line. Optionally, the first main edge portion and the first side edge portion are directly and physically connected to each other. Optionally, the first major edge portion and the first major portion have the same shape. Optionally, except for the portion along the first edge, the outer electrode edge of the first major edge portion is the same as the outer electrode edge of the first major portion. Optionally, the first side edge portion and the first side portion have at least partially different shapes and at least partially different outer contours.

[0055] Figure 1 This is a schematic diagram illustrating the structure of a touch structure according to some embodiments of the present disclosure. (Refer to...) Figure 1 In some embodiments, the touch structure includes a plurality of first touch electrodes TE1 and a plurality of second touch electrodes TE2. The plurality of first touch electrodes TE1 are arranged in multiple rows, each row comprising a plurality of first touch electrodes TE1. Adjacent rows are isolated from each other. The plurality of second touch electrodes TE2 are arranged in multiple columns, each column comprising a plurality of second touch electrodes TE2. Adjacent columns are isolated from each other. Optionally, the touch structure is a mutual capacitance touch structure. Optionally, the plurality of first touch electrodes TE1 are multiple touch scanning electrodes, and the plurality of second touch electrodes TE2 are multiple touch sensing electrodes. Optionally, the plurality of first touch electrodes TE1 are multiple touch sensing electrodes, and the plurality of second touch electrodes TE2 are multiple touch scanning electrodes. The touch electrodes of the touch structure extend to a first edge Ed1, and the touch area terminates outside the first edge.

[0056] In some embodiments, multiple first touch electrodes TE1 of multiple rows extend to the first edge Ed1 of the touch structure. Figure 2 for Figure 1 A magnified view of the first magnified area. Figure 3 for Figure 1 A schematic diagram of the structure of the first touch electrode in the corresponding row of the first enlarged area. (Refer to...) Figures 1 to 3 Each row in the multi-row configuration includes multiple non-edge first electrode blocks NEB1 and first edge electrode blocks EB1. Optionally, the first edge electrode blocks EB1 are arranged along the first edge Ed1. Optionally, the multiple non-edge first electrode blocks NEB1 have the same shape.

[0057] refer to Figure 3 The first edge electrode block EB1 includes a first main edge portion Me1 and a first side edge portion Se1 along the first edge Ed1, respectively; a corresponding one of the plurality of non-edge first electrode blocks NEB1 includes a first main portion Mp1 and a first side portion Sp1 along a first virtual line Vl1 parallel to the first edge Ed1, respectively. In one example, the first main edge portion Me1 corresponds to the first main portion Mp1, and the first side edge portion Se1 corresponds to the first side portion Sp1.

[0058] Figure 4 It shows Figure 3 The boundary of the corresponding part of the electrode in the reference. Figure 4 Along the first virtual line Vl1, the boundaries of the first main portion Mp1 and the first side portion Sp1 are disconnected from each other. However, along the first edge Ed1, the boundaries of the first side edge portion Se1 and the first main edge portion Me1 are connected to each other. Figure 2 and Figure 3 As shown, the first main edge portion Me1 and the first side edge portion Se1 are directly physically connected. Optionally, the first main edge portion Me1 and the first main portion Mp1 have the same shape.

[0059] Figure 5 for Figure 3 The corresponding portion of the middle electrode has an outer electrode edge. An outer electrode edge refers to the actual physical edge within the electrode block. For example, the first major portion Mp1 lacks an outer electrode edge along... Figure 4 The outer electrode edge of the first virtual line Vl1 in the first main portion Mp1 lacks the actual physical edge in the electrode block along the first virtual line Vl1. (Reference) Figure 5 In some embodiments, except for the portion along the first edge Ed1, the outer electrode edge of the first major edge portion Me1 is the same as the outer electrode edge of the first major portion Mp1.

[0060] Reference Figures 2 to 5 The first side edge portion Se1 and the first side portion Sp1 have at least partially different shapes and at least partially different external contours. Figure 6 To explain Figure 3 A schematic diagram of the boundary of the corresponding part of the middle electrode, refer to... Figure 6 In some embodiments, the first side edge portion Se1 includes a first outer sub-portion Se1-1 and a first bridge sub-portion Se1-2, respectively, along the first edge Ed1. (See reference...) Figure 6 and Figure 4 The first bridge portion Se1-2 physically connects the first outer portion Se1-1 directly to the first main edge portion Me1. The first side portion Sp1 includes a first sub-portion Sp1-1 and a second sub-portion Sp1-2 along the first virtual line Vl1. (See reference...) Figure 6 and Figure 5 Except for the portion along the first edge Ed1, the outer electrode edge of the first outer sub-part Se1-1 is the same as the outer electrode edge of the first sub-part Sp1-1. The first sub-part Sp1-1 has the same shape as the first outer sub-part Se1-1. The first bridge sub-part Se1-2 and the second sub-part Sp1-2 have different shapes and different outer contours. (Refer to...) Figure 6 and Figure 4 Along the first virtual line Vl1, the boundaries of the second sub-part Sp1-2 and the first main part Sp1 are disconnected from each other.

[0061] like Figures 1 to 6 As shown, in some embodiments, the first main portion Sp1 and the first main edge portion Me1 have a first translational symmetry, and the first outer sub-part Se1-1 and the first sub-part Sp1-1 have a second translational symmetry. Optionally, the first translational symmetry and the second translational symmetry are the same.

[0062] like Figure 3 As shown, in some embodiments, the first side portion Sp1 is at least a portion of the protrusion of a corresponding one of a plurality of non-edge first electrode blocks NEB1; the first side edge portion Se1 is the protrusion of the first edge electrode block EB1.

[0063] If the touch structure is designed uniformly throughout the entire structure, some electrode blocks may not be able to connect along the edges of the touch structure. Figure 7 A schematic diagram illustrating the structure of a touch structure according to some embodiments of the present disclosure. (Refer to...) Figure 7Along the first edge Ed1 of the touch structure, the touch structure also includes residual electrode blocks RBa and RBb, which are not connected to the first edge electrode block EB1, respectively. The presence of residual electrode blocks such as RBa and RBb in the touch structure results in a reduction in the adjacent electrode interfaces between multiple first touch electrodes and multiple second touch electrodes along an edge such as the first edge Ed1. Without compensation, the reduced adjacent electrode interfaces lead to a reduction in mutual capacitance along these edges, resulting in non-uniform mutual capacitance and touch performance issues. The first edge Ed1 can be any edge of the touch structure, such as an edge along the side of the touch structure, an edge along a corner of the touch structure, or an edge along an internal window region of the touch structure. The internal window region can be a region in which a hole is punched through the touch structure.

[0064] To enhance the uniformity of mutual capacitance and touch performance of the entire touch structure, the first edge electrode block EB1 in this disclosure is formed with a structure different from that of the plurality of non-edge first electrode blocks NEB1, thereby preventing the presence of residual electrode blocks along the edge. In the touch structure of the present invention, substantially more uniform mutual capacitance and touch performance along the edge can be obtained.

[0065] Refer again Figures 1 to 6 In some embodiments, the first edge electrode block EB1 further includes a second side edge portion Se2. The first side edge portion Se1, the first main edge portion EB1, and the second side edge portion Se2 are arranged sequentially along the first edge Ed1. Similarly, a corresponding one of a plurality of non-edge first electrode blocks NEB1 further includes a second side portion Sp2. The first side portion Sp1, the first main portion Mp1, and the second side portion Sp2 are arranged sequentially along a first virtual line Vl1. Along the first virtual line Vl1, the boundaries of the first main portion Mp1 and the first side portion Sp1 are disconnected from each other, and the boundaries of the first main portion Mp1 and the second side portion Sp2 are disconnected from each other. The first main edge portion Me1 and the first side edge portion Se1 are directly and physically connected to each other; and the first main edge portion Me1 and the second side edge portion Se2 are directly and physically connected to each other. The first side edge portion Se1 and the first side portion Sp1 have at least partially different shapes and at least partially different external contours; and the second side edge portion Se2 and the second side portion Sp2 have at least partially different shapes and at least partially different external contours.

[0066] refer to Figure 6 In some embodiments, the first side edge portion Se1 includes a first outer sub-portion Se1-1 and a first bridge portion Se1-2, respectively, along the first edge Ed1; the second side edge portion Se2 includes a second outer sub-portion Se2-1 and a second bridge portion Se2-2, respectively, along the first edge Ed1. (See reference...) Figure 6 and Figure 4 The first bridge portion Se1-2 physically connects the first outer sub-portion Se1-1 directly to the first main edge portion Me1; and the second bridge portion Se2-2 physically connects the second outer sub-portion Se2-1 directly to the first main edge portion Me1. The first side portion Sp1 includes a first sub-portion Sp1-1 and a second sub-portion Sp1-2 along the first virtual line Vl1; the second side portion Sp2 includes a third sub-portion Sp2-1 and a fourth sub-portion Sp2-2 along the first virtual line Vl1. (Reference) Figure 6 and Figure 5 Except for the portion along the first edge Ed1, the outer electrode edge of the first outer sub-part Se1-1 is the same as the outer electrode edge of the first sub-part Sp1-1; and except for the portion along the first edge Ed1, the outer electrode edge of the second outer sub-part Se2-1 is the same as the outer electrode edge of the third sub-part Sp2-1. The first sub-part Sp1-1 and the first outer sub-part Se1-1 have the same shape; the third sub-part Sp2-1 and the second outer sub-part Se2-1 have the same shape. The first bridge sub-part Se1-2 and the second sub-part Sp1-2 have different shapes and different outer contours; the second bridge sub-part Se2-2 and the fourth sub-part Sp2-2 have different shapes and different outer contours. (Refer to...) Figure 6 and Figure 4 Along the first virtual line Vl1, the boundaries of the second sub-part Sp1-2 and the first main part Sp1 are disconnected from each other; and along the first virtual line, the boundaries of the fourth sub-part Sp2-2 and the first main part Sp1 are disconnected from each other.

[0067] like Figures 1 to 6 As shown, in some embodiments, the first main portion Sp1 and the first main edge portion Me1 have a first translational symmetry, the first outer sub-part Se1-1 and the first sub-part Sp1-1 have a second translational symmetry, and the second outer sub-part Se2-1 and the third sub-part Sp2-1 have a third translational symmetry. Optionally, the first, second, and third translational symmetries are identical.

[0068] like Figure 3 As shown, in some embodiments, the first side portion Sp1 and the second side portion Sp2 are at least portions of the protrusions of a corresponding one of the plurality of non-edge first electrode blocks NEB1 (e.g., Figure 3 The upper and lower protrusions of one of the multiple non-edge first electrode blocks NEB1; the first side edge portion Se1 and the second side edge portion Se2 are respectively the protrusions of the first edge electrode block EB1 (e.g., Figure 3 The upper and lower protrusions of the first edge electrode block EB1 in the middle.

[0069] In some embodiments, refer again Figure 1 The plurality of columns of the plurality of second touch electrodes TE2 include a plurality of non-edge columns Cne and a column Cea adjacent to the edge, wherein the column Cea adjacent to the edge is directly adjacent to a plurality of first edge electrode blocks from a plurality of rows of the plurality of first touch electrodes TE1, respectively. The plurality of first edge electrode blocks include, as shown in the figure Figure 1 The first edge electrode block EB1 is shown. Each of the plurality of first edge electrode blocks (e.g., first edge electrode block EB1) is along the first edge Ed1. Figure 1 As shown, the adjacent edge column Cea includes multiple adjacent edge electrode blocks EAB electrically connected together; and the corresponding columns of the multiple non-edge columns Cne include multiple non-edge second electrode blocks NEB2 electrically connected together.

[0070] Figure 8 for Figure 1 A magnified view of the second magnified area. See also Figure 8 Except that the first portion P1 is directly adjacent to the first side edge portion Se1 in adjacent rows of multiple rows, the outer electrode edge of the corresponding one of the multiple adjacent edge electrode blocks EAB is the same as the outer electrode edge of the corresponding one of the multiple non-edge second electrode blocks NEB2. Optionally, the first portion P1 is a protrusion of the corresponding one of the multiple adjacent edge electrode blocks NEB2. Compared with the other protrusions of the corresponding one of the multiple adjacent edge electrode blocks NEB2, the first portion P1 is shortened.

[0071] In some embodiments, except that in adjacent rows of the plurality of rows, a first portion P1 is directly adjacent to a first side edge portion Se1, and in second adjacent rows of the plurality of rows, a second portion P2 is directly adjacent to a second side edge portion Se2, the outer electrode edge of a corresponding one of the plurality of adjacent edge electrode blocks EAB is the same as the outer electrode edge of a corresponding one of the plurality of non-edge second electrode blocks NEB2. Optionally, the first portion P1 and the second portion P2 are respectively protrusions of a corresponding one of the plurality of adjacent edge electrode blocks NEB2. Compared to the other protrusions of the corresponding one of the plurality of adjacent edge electrode blocks NEB2, the first portion P1 is shortened, and the second portion P2 is shortened.

[0072] Reference Figure 1 In some embodiments, the touch structure further includes multiple first touch signal lines SL1 connected to multiple rows respectively; and multiple second touch signal lines SL2 connected to multiple columns respectively. For example... Figure 1As shown, in some embodiments, on the left side, multiple rows of multiple first touch electrodes TE1 extend to the second edge Ed2 of the touch structure; on the right side, multiple columns of multiple first touch electrodes TE1 extend to the first edge Ed1 of the touch structure. Optionally, the second edge Ed2 is opposite to the first edge Ed1. In some embodiments, multiple first touch signal lines SL1 are respectively connected, for example, along the second edge Ed2 to the electrode blocks of the multiple first touch electrodes TE1 in the multiple rows on the left side. However, the multiple first touch signal lines SL1 are not directly connected, for example, along the first edge Ed1 to the electrode blocks of the multiple first touch electrodes TE1 in the multiple rows on the right side.

[0073] In some embodiments, the first edge electrode block EB1 is indirectly electrically connected to a corresponding one of a plurality of first touch signal lines SL1 via at least a plurality of non-edge first electrode blocks NEB1. However, the first edge electrode block EB1 is not directly connected to any one of the plurality of first touch signal lines SL1 or the plurality of second touch signal lines SL2.

[0074] Figure 9 This is a schematic diagram illustrating the structure of a touch structure according to some embodiments of the present disclosure. Figure 10 yes Figure 9 A magnified view of the third magnified area. (See reference) Figure 9 and Figure 10 In some embodiments, a corresponding row among the plurality of rows further includes a second edge electrode block EB2 and a first remaining electrode block RB1. The second edge electrode block EB2 and the first remaining electrode block RB1 are along a second edge Ed2. Optionally, the second edge Ed2 is the edge opposite to the first edge Ed1. Optionally, a corresponding row includes a second edge electrode block EB2 and a first remaining electrode block RB1 along the second edge Ed2 (on the left), a plurality of non-edge electrode blocks NEB in the middle of the row, and a first edge electrode block EB1 along the first edge Ed1 (on the right). The plurality of non-edge electrode blocks NEB in the middle connect the first edge electrode block EB1 and the second edge electrode block EB2 together.

[0075] refer to Figure 9 and Figure 10 In some embodiments, the second edge electrode block EB2 and the first remaining electrode block RB1 are directly connected to one of the plurality of first touch signal lines SL1, while the first remaining electrode block RB1 is isolated from the electrode blocks of any adjacent row in the plurality of rows.

[0076] See Figure 10In some embodiments, a corresponding one of the plurality of first touch signal lines SL1 includes a first branch line Bl1 and a second branch line Bl2 that are electrically connected in parallel (e.g., connected to a main line SL1 of the corresponding one of the plurality of first touch signal lines SL1). The second edge electrode block EB2 is directly connected to the first branch line Bl1, and the first residual electrode block RB1 is directly connected to the second branch line Bl2.

[0077] refer to Figure 9 The first remaining electrode block RB1 is isolated from the electrode blocks of any adjacent rows in the plurality of rows. Figure 11 for Figure 9 A schematic diagram of the structure of the first touch electrode in the corresponding row of the third enlarged area, see reference. Figure 11 The first remaining electrode block RB1 is also isolated from the second edge electrode block EB2. The first remaining electrode block RB1 and the second edge electrode block EB2 are disconnected from each other because they exist along the second edge Ed2 of the touch structure. In the corresponding one of the plurality of non-edge first electrode blocks NEB1 that is not along the second edge Ed2 or the first edge Ed1, the protrusion of the electrode block is connected to the central portion.

[0081] refer to Figure 9 and Figure 10 In some embodiments, the first remaining electrode block RB1, the second edge electrode block EB2, and the second remaining electrode block RB2 are respectively directly connected to one of the multiple first touch signal lines SL1, while the first remaining electrode block RB1 is isolated from the electrode blocks of any adjacent row in the multiple rows, and the second remaining electrode block RB2 is isolated from the electrode blocks of any adjacent row in the multiple rows.

[0082] See Figure 10 In some embodiments, a corresponding one of the plurality of first touch signal lines SL1 includes a first branch line Bl1, a second branch line Bl2, and a third branch line Bl3 that are electrically connected in parallel (e.g., connected to a main line of the corresponding one of the plurality of first touch signal lines SL1). A second edge electrode block EB2 is directly connected to the first branch line Bl1, a first residual electrode block RB1 is directly connected to the second branch line Bl2, and the second residual electrode block RB2 is directly connected to the third branch line Bl3.

[0083] refer to Figures 11 to 13 The first remaining electrode block RB1 is isolated from the electrode blocks of any adjacent row in the multi-row array, and the second remaining electrode block RB2 is isolated from the electrode blocks of any adjacent row in the multi-row array. (Reference) Figure 11The first remaining electrode block RB1 is also isolated from the second edge electrode block EB2, and the second remaining electrode block RB2 is also isolated from the second edge electrode block EB2. The first remaining electrode block RB1 and the second edge electrode block EB2 are disconnected from each other, and the second remaining electrode block RB2 and the second edge electrode block EB2 are disconnected from each other because they exist along the second edge Ed2 of the touch structure. In the corresponding one of the plurality of non-edge first electrode blocks NEB1 that is not along the second edge Ed2 or the first edge Ed1, the protrusion of the electrode block is connected to the central portion. In one example, the second edge electrode block EB2 corresponds to the second main portion Mp2 of the corresponding one of the plurality of non-edge first electrode blocks NEB1, the first remaining electrode block RB1 corresponds to the third side portion Sp3 of the corresponding one of the plurality of non-edge first electrode blocks NEB1, and the second remaining electrode block RB2 corresponds to the fourth side portion Sp4 of the corresponding one of the plurality of non-edge first electrode blocks NEB1.

[0084] In some embodiments, a corresponding one of the plurality of non-edge first electrode blocks NEB1 includes a second main portion Mp2, a third side portion Sp3, and a fourth side portion Sp4, respectively, along a second virtual line Vl2 parallel to the second edge Ed2. Along the second virtual line Vl2, the boundaries of the second main portion Mp2 and the third side portion Sp3 are disconnected from each other; and the boundaries of the second main portion Mp2 and the fourth side portion Sp4 are disconnected from each other. Optionally, the second edge electrode block EB2 and the second main portion Mp2 have the same shape; the first remaining electrode block RB1 and the third side portion Sp3 have the same shape, and the second remaining electrode block RB2 and the fourth side portion Sp4 have the same shape.

[0086] Optionally, the second edge electrode block EB2 and the first edge electrode block EB1 are respectively the first electrode block and the last electrode block in the same row of multiple rows.

[0087] The presence of residual electrode blocks, such as a first residual electrode block RB1 and a second residual electrode block RB2, in the touch structure results in a reduction in the adjacent electrode interfaces between multiple first touch electrodes TE1 and multiple second touch electrodes TE2 along an edge, such as a second edge Ed2. Without compensation, this reduced adjacent electrode interface leads to a decrease in mutual capacitance along these edges, resulting in non-uniform mutual capacitance and touch performance issues. The second edge Ed2 can be any edge of the touch structure, such as an edge along the side of the touch structure, an edge along a corner of the touch structure, or an edge along an internal window region of the touch structure. The internal window region can be a region in which a hole is punched through the touch structure.

[0088] To enhance the uniformity of mutual capacitance and touch performance of the entire touch structure, branch lines can be formed to electrically connect the first remaining electrode block RB1 to the second edge electrode block EB2, and the second remaining electrode block RB2 to the second edge electrode block EB2. In the touch structure of the present invention, substantially more uniform mutual capacitance and touch performance along the edges can be obtained.

Figure 14 In some embodiments, the first edge electrode block EB1 includes a first main edge portion Me1 and a first side edge portion Se1, respectively, along the first edge Ed1. A plurality of first touch electrodes TE1 and a plurality of second touch electrodes TE2 are located in the same layer and each includes a main portion MP and a protruding portion PP.

Figure 14 and Figure 15 As shown, at least one of the plurality of adjacent edge electrode blocks EAB includes a corresponding main portion RMP, a truncated protrusion TP, and a plurality of non-truncated protrusions NTP. At least a few of the plurality of non-truncated protrusions NTP have substantially the same shape and size, particularly non-truncated protrusions along one side of the corresponding main portion RMP rather than at the corners of the main portion RMP. Optionally, the truncated protrusions TP also run along the side of the main portion.

[0091] The truncated protrusion TP extends along the first direction D1 from the corresponding main portion RMP of one of the multiple adjacent edge electrode blocks EAB. Several non-truncated protrusions NTP, along one side of the corresponding main portion RMP identical to the truncated protrusion TP, also extend along the first direction D1 from their respective main portions RMP.

Reference Figures 14 to 16 In some embodiments, the edge of the truncated protrusion TP is spaced apart from the first edge Ed1 by a gap G.
