According to the specific structure of the touch substrate 1 above, in the touch substrate 1 according to the embodiments of the present disclosure, the width of the second part 1101b perpendicular to the extending direction of the second part 1101b is larger than the width of the first part 1101a perpendicular to the extending direction of the first part 1101a, and / or the width of the second part 1101b perpendicular to the extending direction of the second part 1101b is larger than the width of the third part 1101c perpendicular to the extending direction of the third part 1101c, so as to widen the width of the corner part at the corner where the second part 1101b is located, thereby reducing the risk of disconnection of the touch signal line 110 at the corner.

The second part 110 is divided into (parts B2 and B2), and each set contains multiple corner portions of the second part 110 1b is arranged at intervals along the first direction, and the first direction is the first portion 110 It intersects with both the extension direction of 1a and the extension direction of the second portion 1101b.

[0044] Exemplary, the first direction is perpendicular to the direction of extension of the second portion 1101b.

[0045] For example, the angle between the first direction and the direction of extension of the first portion 1101a is 45 It is below °.

[0046] In the touch substrate 1 according to the above embodiment, a plurality of the corner portions included in each set The two parts 1101b are arranged at intervals along the first direction, and the first direction is the The extension direction of the first portion 1101a intersects with the extension direction of the second portion 1101b. By setting it so that the width of the second portion 1101b is widened, the first portion 110 In a direction perpendicular to the extension direction of 1a, the entire corner portion included in the touch signal line 110 The width can be ensured to remain unchanged, and therefore, the touch substrate 1 according to the above embodiment is This reduces the risk of breakage of the touch signal line 110 at the corner, and also reduces the risk of breakage of the touch base This avoids increasing the frame width occupied by the entire corner portion of board 1, and contributes to narrowing the frame of the touch substrate 1. It is advantageous.

[0047] In some embodiments, in the same set of corner portions, the first direction and the previous The angle a1 between the extension direction of one portion and the surrounding area is set such that 30° ≤ a1 ≤ 80°.

[0048] The above setting method increases the frame width occupied by the entire corner portion of the touch board 1. In addition to avoiding the corners, the width of the second portion 1101b is further maximized, and the corners are touched This further reduces the risk of disconnection of the signal line 110.

[0049] In some embodiments, the extending direction of the second portion is not perpendicular to the first direction, but the same The angle between the first and second parts, and the third and second parts, which belong to one touch signal line. The angles between them are all set to be obtuse angles.

[0050] In the same touch signal line, the angle between the first portion and the second portion, and the The angles between part 3 and part 2 are all obtuse angles.

[0051] The above setting method reduces the risk of breakage of the touch signal line 110 at the corner. At the same time, this reduces the frame width occupied by the entire corner portion of the touch substrate 1. This is advantageous for narrowing the frame of the touch substrate 1.

[0052] In some embodiments, there are multiple second parts 1101b belonging to a set of corner sections. The minimum interval between them is the interval between the multiple first parts 1101a in the corner portion of the set. Larger and / or between the multiple third parts 1101c in the corner portion of the set It is larger than the interval.

[0053] The above setting method increases the frame width occupied by the entire corner portion of the touch board 1. In addition to avoiding the corners, the width of the second portion 1101b is further maximized, and the corners are This further reduces the risk of disconnection of the signal line 110. The formula further improves the risk of a short circuit occurring between adjacent second parts 1101b. It reduces the level.

[0055] In some embodiments, the third portion is positioned closer to the touch area than the first portion. Set to this.

[0056] The above setting method reduces the difficulty of laying out the touch signal lines, and the touch This is advantageous not only for ensuring connection performance between the signal line and the touch electrode, but also This reduces the risk of a break in the touch signal line 110 at the corner, and also reduces the risk of a break in the touch signal line 110. This is advantageous in reducing the frame width occupied by the entire corner portion of the substrate 1, and touch This is advantageous for narrowing the frame of substrate 1.

[0057] In some embodiments, the width of the second portion perpendicular to the extending direction of the second portion is the The width of the first portion perpendicular to the extension direction of the portion is 1.5 to 4 times the width of the first portion.

[0058] The above setting method reduces the risk of breakage of the touch signal line 110 at the corner. At the same time, this reduces the frame width occupied by the entire corner portion of the touch substrate 1. This is more advantageous and beneficial for narrowing the frame of the touch substrate 1.

[0059] In some embodiments, the touch signal line 110 is provided with a first conductive layer and a second conductive layer in a different layer. The material includes two conductive layers, and both the first conductive layer and the second conductive layer include the corner portion. The second portion 1101b in the first conductive layer is the second portion in the second conductive layer It is joined to part 1101b.

[0060] For example, the orthogonal projection of the first conductive layer on the base of the touch substrate 1 is shown on the base. The orthogonal projection of the second conductive layer overlaps at least partially. Exemplarily, the first Other than the second portion 1101b between the conductive layer and the second conductive layer are bonded. ru.

[0061] Exemplary, an insulating layer is provided between the first conductive layer and the second conductive layer, and the insulating layer is They are manufactured using inorganic materials such as silicon nitride.

[0062] For example, the orthogonal projection of a corner portion included in the first conductive layer on the base is It overlaps with the orthogonal projection of the corner portion included in the second conductive layer in the -.

[0063] For example, both the first conductive layer and the second conductive layer are manufactured using a metallic material.

[0064] The second portion 1101b is relatively wide in a direction perpendicular to its own extension direction. Because it has width, the second portion 1101b of the first conductive layer is placed in the second conductive layer By setting the first conductive layer to bond to the second portion 1101b, The second lead wire layer can be made to communicate more effectively, and the touch signal line 110 can be touched This allows for better uniformity of the signal and improved reliability of the signal line itself.

[0065] Furthermore, in order to ensure uniformity of the transmission signal of the touch signal line 110, the touch board 1 The load on each touch signal line 110 must be uniform, and therefore the touch signal line 110 During the design process, it became necessary to design related resistance compensation units, and in this way, each The effect of having uniform resistance in the signal line 110 is achieved more effectively. And the layout space Given the limited timeframe and the effectiveness of compensation, the design of compensation routing is feasible during the process. To perform relevant compensation using the minimum possible linewidth and to ensure the connectivity of signal channels Furthermore, a double-layer metal wiring parallel design is employed to reduce the risk of signal channel interruption.

[0066] As shown in Figure 4, in some embodiments, the touch substrate further comprises the first conductive The touch insulating layer is provided between the first conductive layer and the second conductive layer, and the touch insulating layer is the first The via hole 12 is included, and the orthogonal projection of the first via hole 12 onto the base of the touch substrate 1. This is the orthogonal projection and overlay of the second portion 1101b in the first conductive layer on the base. - Wrapped and the positive of the second portion 1101b in the second conductive layer on the base The projection overlaps with the second portion 1101b in the first conductive layer and the second conductive layer The second portion 1101b in the electrolayer is connected by the first via hole 12. .

[0067] As shown in Figure 4, in some embodiments, the first via hole 12 in the base The extension direction of the orthogonal projection is the same as the extension direction of the second portion 1101b.

[0068] For example, the second portion 11 of the first conductive layer on the base of the touch substrate 1 The orthogonal projection of 01b is of the second portion 1101b in the second conductive layer on the base.
