[0156] The present disclosure will now be described in more detail with reference to the following examples. It should be noted that the following description of some embodiments is given here only for the purpose of illustration and description. It is not intended to be exhaustive or limited to the precise form disclosed.

[0157] With the development of science and technology, the development of smartphone display screens is also changing with each passing day. At this stage, placing the front camera in the display area (AA Hole) has become the current mainstream design. At the same time, people's requirements for touch functions are becoming higher and higher, and at the same time, the requirements for the AA Hole area are also getting higher and higher. However, due to the lack of touch pattern in the AA hole area, the touch performance here is bound to decline. The touch pattern here needs to be compensated but not over-compensated. In addition, because the packaging layer under the touch layer around the AA Hole cannot be leveled enough, there is a risk of bridge breaking when a single bridge is connected, resulting in the entire channel being broken and the touch signal transmission path being disconnected. Therefore, the biggest problem with existing touch display screens is: how to design an AA Hole bridge solution to achieve capacitance compensation without over-compensation, and to reduce the risk of bridge breaking.

[0158] The present disclosure particularly provides a touch structure and a display panel, which substantially eliminate one or more problems caused by the limitations and disadvantages of the related art. In one aspect, the present disclosure provides a touch structure. In some embodiments, a touch structure comprises: a plurality of first grid electrodes extending along a first direction and a plurality of second grid electrodes extending along a second direction intersecting the first direction, wherein the touch structure is confined to a touch area and does not exist in a window area surrounded by the touch area; wherein the plurality of first grid electrodes include at least one cross-window row separated by the window area, and the at least one cross-window row includes a first cross-window row, which includes: a first window grid block, which is adjacent to the window area and is on a first side of the window area; a first conductive plate, which is directly connected to a plurality of grid lines of the first window grid block; and a first non-window grid block, which is on a side of the first window grid block away from the window area; wherein the plurality of The second grid electrode includes at least one cross-window column separated by a window area, and the at least one cross-window column includes a first cross-window column, which includes: a second window grid block, which is located on the second side of the window area; a second conductive plate, which is directly connected to multiple grid lines of the second window grid block; and a second non-window grid block, which is located on the side of the second window grid block away from the window area; wherein the first conductive plate and the second conductive plate extend along the first part and the second part of the periphery of the window area respectively; the area of ​​the first conductive plate is positively correlated with the area of ​​the first window grid block missing relative to the first non-window grid block, and the area of ​​the second conductive plate is positively correlated with the area of ​​the second window grid block missing relative to the second non-window grid block.

[0159] Optionally, the first direction is a row direction, the second direction is a column direction, and the row direction and the column direction intersect each other. Optionally, the row direction and the column direction are perpendicular to each other.

[0160] The first grid electrode and the second grid electrode are each composed of a plurality of grid lines, and the line width thereof is generally in the range of 1 μm to 50 μm, for example, 4 μm. Therefore, it is particularly difficult to connect adjacent window grid blocks through grid lines, and often results in poor connection. The present disclosure adopts a novel and advantageous touch electrode design, avoiding the problems in related touch control structures.

[0161] Figure 1 Schematic diagram showing a touch structure in some embodiments of the present disclosure. Figure 1In some embodiments, the touch structure includes a plurality of first grid electrodes TE1 (Rx channels, i.e., receiving electrode channels) and a plurality of second grid electrodes TE2 (Tx channels, i.e., transmitting electrode channels). Optionally, the touch structure is a mutual capacitance touch structure. Optionally, the plurality of first grid electrodes TE1 are a plurality of touch scanning electrodes, and the plurality of second grid electrodes TE2 are a plurality of touch sensing electrodes. Optionally, the plurality of first grid electrodes TE1 are a plurality of touch sensing electrodes, and the plurality of second grid electrodes TE2 are a plurality of touch scanning electrodes. The touch structure is defined in the touch area TCR and does not exist in the window area WR surrounded by the touch area TCR. For example, the touch structure may be a touch structure in a display panel, wherein the touch area TCR substantially overlaps with the display area of ​​the display panel, and the window area WR is an area in the display panel having a hole for mounting an accessory such as a camera lens or a fingerprint sensor. The display panel is configured to display an image in at least a portion of the touch area TCR. In one example, in the window region WR, there are no display elements and touch structures of the display panel; in at least a portion of the display region or the touch region TCR, there are both display elements and touch structures of the display panel.

[0162] refer to Figure 1 In some embodiments, a plurality of first grid electrodes TE1 are arranged in a plurality of rows, and each first grid electrode TE1 is one of the plurality of first grid electrodes TE1; a plurality of second grid electrodes TE2 are arranged in a plurality of columns, and each second grid electrode TE2 is one of the plurality of second grid electrodes TE2. In some embodiments, at least one row of the plurality of rows of first grid electrodes TE1 spans the window region WR. For example, Figure 1 As shown, the cross-window row Rwc of the plurality of first grid electrodes TE1 crosses the window region WR. The first grid electrodes TE1 in the cross-window row Rwc are divided into two parts (a part on the left side of the window region WR and a part on the right side of the window region WR) by the window region WR. In some embodiments, at least one column of the plurality of columns of second grid electrodes TE2 passes through the window region WR. For example, Figure 1 As shown, the cross-window column Cwc of the plurality of second grid electrodes TE2 spans the window region WR. The second grid electrodes TE2 in the cross-window column Cwc are divided into two parts (a part on the upper side of the window region WR and a part on the lower side of the window region WR) by the window region WR.

[0163] Figure 2 is a schematic diagram illustrating a window area in some embodiments according to the present disclosure. Figure 3 is an enlarged view of a touch structure surrounding a window area according to some embodiments of the present disclosure. Figure 4AFIG. 1 is a further enlarged view of the touch structure surrounding the window area according to some embodiments of the present disclosure. Figure 2 In some embodiments, the window region WR generally has at least four sides, including a first side S1, a second side S2, a third side S3, and a fourth side S4. Figures 2 to 4A In some embodiments, the cross-window row Rwc of the plurality of first grid electrodes TE1 includes a first window grid block MB1 and a third window grid block MB3 located at the first side S1 and the third side S3 of the window region WR, respectively; a first conductive plate CP1 directly connected to a plurality of grid lines of the first window grid block MB1; a third conductive plate CP3 directly connected to a plurality of grid lines of the third window grid block MB3; and a third conductive bridge CB3 connecting the first conductive plate CP1 and the third conductive plate CP3. Figures 2 to 4A In some embodiments, the cross-window column Cwc of the plurality of second grid electrodes TE2 includes a second window grid block MB2 and a fourth window grid block MB4 respectively located on the second side S2 and the fourth side S4 of the window region WR; a second conductive plate CP2 directly connected to a plurality of grid lines of the second window grid block MB2; a fourth conductive plate CP4 directly connected to a plurality of grid lines of the fourth window grid block MB4; and a first conductive bridge CB1 connecting the second conductive plate CP2 and the fourth conductive plate CP4.

[0164] In the present touch structure, adjacent window grid blocks in the same row separated by the window region WR (for example, the first window grid block MB1 and the third window grid block MB3) are connected via a conductive connection bridge (for example, the third conductive bridge CB3) with the aid of conductive plates (for example, the first conductive plate CP1 and the third conductive plate CP3); adjacent window grid blocks in the same column separated by the window region WR (for example, the second window grid block MB2 and the fourth window grid block MB4) are connected via a conductive connection bridge (for example, the first conductive bridge CB1) with the aid of conductive plates (for example, the second conductive plate CP2 and the fourth conductive plate CP4).

[0165] refer to Figure 2 and Figure 4A The first conductive plate CP1, the second conductive plate CP2, the third conductive plate CP3 and the fourth conductive plate CP4 extend around the first part P1, the second part P2, the third part P3 and the fourth part P4 of the periphery of the window area WR respectively; and the first conductive bridge CB1 and the third conductive bridge CB3 extend around the first part P1 and the third part P3 of the window area WR respectively.

[0166] See also Figure 1, the touch structure of the present disclosure also includes a first non-window grid block NWB1 and a second non-window grid block NWB2. The multiple grid line patterns of the first non-window grid block NWB1 and the second non-window grid block NWB2 are not missing due to the setting of the window area WR, that is, the first window grid block NWB1 is on the side of the first window grid block MB1 and the third window grid block MB3 away from the window area WR; and the second window grid block NWB2 is on the side of the second window grid block MB2 and the fourth window grid block MB4 away from the window area WR. The area of ​​the first non-window grid block NWB1 and the area of ​​the second non-window grid block NWB2 are generally equal. As Figure 1 As shown, in this embodiment, the first non-window grid block NWB1 and the second non-window grid block NWB2 mainly include a central sheet grid sub-block and a plurality of finger grid sub-blocks arranged around the sheet grid sub-block. Due to the existence of the window area WR, the grid lines of the first window grid block MB1, the second window grid block MB2, the third window grid block MB3 and the fourth window grid block MB4 will be missing. The present disclosure will set a compensation mechanism of the touch structure around the window area WR to compensate for the pattern missing of these window grid blocks while establishing the touch signal transmission path in the row direction and column direction of the window area WR.

[0167] The window area WR will occupy different grid blocks due to different setting positions and sizes, so the grid line patterns of the window grid blocks adjacent to the window area will also be different.

[0168] like Figure 1 As shown, in this embodiment, the window region WR is inside four adjacent grid blocks, and the window region WR only occupies one row of first grid electrodes TE1 and one column of second grid electrodes TE2. That is, the window region WR only has a cross-window row Rwc in one row of first grid electrodes TE1 and only has a cross-window column Cwc in one column of second grid electrodes TE2. In this case, the grid lines of the window grid block adjacent to the window region WR belong to the central sheet-shaped grid sub-block part, rather than the finger-shaped grid sub-block part as the outer edge.

[0169] Furthermore, if Figures 2 to 4A As shown, the first conductive plate CP1 is used to connect the first window grid block MB1, and the second conductive plate CP2 is used to connect the second grid block MB2. Figure 3 and Figure 4AAs shown, the first conductive plate CP1 is directly connected to multiple grid lines of the first window grid block MB1, and the second conductive plate CP2 is directly connected to multiple grid lines of the second window grid block MB2. The length L1 of the first conductive plate CP1 extending along the periphery of the window area WR is greater than the length L2 of the second conductive plate CP2 extending along the periphery of the window area WR. In the case where the window grid block units of the first grid electrode TE1 and the second grid electrode TE2 are substantially the same as shown in the figure, the first conductive plate CP1 needs to compensate for the larger grid line loss, and therefore, the area of ​​the first conductive plate CP1 should be greater than the area of ​​the second conductive plate CP2. Figure 2 As shown in A to FIG. 4, when the first conductive plate CP1 and the second conductive plate CP2 are both arc-shaped structures (for example, fan rings), the area of ​​the first window grid block MB1 is greater than 1 / 2 of the area of ​​the first non-window grid block NWB1, and the area of ​​the second grid window block MB2 is greater than 1 / 2 of the area of ​​the second non-window grid block NWB2, the width of the first conductive plate CP1 along the vertical direction of the interface between the first conductive plate CP1 and the first window grid block MB1 can be set to be greater than the width of the second conductive plate CP2 along the vertical direction of the interface between the second conductive plate CP2 and the second window grid block MB2, so as to compensate the self-capacitance of the grid block with a larger grid line pattern missing by a larger conductive plate. When the first conductive plate CP1 and the second conductive plate CP2 are fan rings, the length L1 of the first conductive plate CP1 extending along the periphery of the window area WR can be the length of the fan ring of the first conductive plate CP1 close to the window area WR. Similarly, the length L2 of the second conductive plate CP2 extending along the periphery of the window area WR can also be the length of the fan ring of the second conductive plate CP2 close to the window area WR.

[0170] In one embodiment, when the area of ​​the first window grid block is smaller than 1 / 2 of the area of ​​the first non-window grid block, and the area of ​​the second grid window block is smaller than 1 / 2 of the area of ​​the second non-window grid block; and the length of the first conductive plate close to the window area is smaller than the length of the second conductive plate close to the window area, since the first window grid block lacks more metal grid patterns relative to the first non-window grid block, the width of the first conductive plate along the direction perpendicular to the interface between the first conductive plate and the first window grid block can be set to be greater than the width of the second conductive plate along the direction perpendicular to the interface between the second conductive plate and the second window grid block.

[0171] In one embodiment, when the area of ​​the first window grid block is less than 1 / 2 of the area of ​​the first non-window grid block and the area of ​​the second grid window block is greater than 1 / 2 of the area of ​​the second non-window grid block, since the first window grid block lacks more metal grid patterns relative to the non-window grid block, the width of the first conductive plate along the direction perpendicular to the interface between the first conductive plate and the first window grid block can be set to be greater than the width of the second conductive plate along the direction perpendicular to the interface between the second conductive plate and the second window grid block.

[0172] Furthermore, if Figure 3 and Figure 4A As shown, the touch control structure of the embodiment of the present disclosure further includes a second conductive bridge CB2, which connects the first end of the second conductive plate CP2 and the first end of the fourth conductive plate CP4. That is, the first end of the second conductive plate CP2 is connected to one end of the first conductive bridge CB1, and the second end is connected to the first end of the second conductive bridge CB2. The second conductive plate CP2 is connected to the fourth conductive plate CP4 through both the first conductive bridge CB1 and the second conductive bridge CB2, thereby using a dual channel of two conductive bridges in the cross-window column Cwc to reduce the risk of circuit breakage. In addition, as shown in FIG. Figure 3 and 4A As shown, the touch structure of the disclosed embodiment further includes a third auxiliary conductive bridge CB32, which directly connects the first conductive plate CP1 and the third conductive plate CP3 together, thereby realizing dual channels of two conductive bridges in the cross-window row Rwc, thereby reducing the risk of circuit breaking.

[0173] like Figure 4B As shown, the touch structure of the embodiment of the present disclosure forms dual Tx channels and dual Rx channels in the row direction and the column direction in the window region WR, respectively, thereby reducing the risk of circuit breaking.

[0174] like Figure 2 A and Figure 4A In this embodiment, since a large area of ​​grid line patterns is missing, a relatively large first conductive plate CP1, a second conductive plate CP2, a third conductive plate CP3 and a fourth conductive plate CP4 are used for the first window grid block MB1, the second window grid block MB2, the third window grid block MB3 and the fourth window grid block MB4, respectively, wherein the first conductive plate CP1 and the third conductive plate CP3 have a larger width than the second conductive plate CP2 and the fourth conductive plate CP4. In order to prevent the capacitance compensation from being too large, in the embodiment of the present disclosure, the first conductive bridge CB1 and the second conductive bridge CB2 are arranged in a layer different from the first conductive plate CP1 and the second conductive plate CP3 to avoid the generation of mutual capacitance between the first conductive bridge CB1 and the first conductive plate CP1 and between the second conductive bridge CB2 and the third conductive plate CP3. For example Figure 4AAs shown, a first via hole V1, a second via hole V2, a third via hole V3 and a fourth via hole V4 are formed at the connection between the second conductive plate CP2 and the fourth conductive plate CP4 and the first conductive bridge CB1 and the second conductive bridge CB2, respectively. Figure 4C The edge shown Figure 3 In addition, by arranging the metal patterns of the first conductive plate CP1 and the first conductive bridge CB1 in different layers, short circuits caused by residual metal particles in the exposure, development, and etching processes during the formation of these metal patterns can also be avoided.

[0175] In order to reduce the process complexity, other layers can be arranged in the same layer, for example Figure 4A As shown in FIG. 1 , the third conductive bridge CB3 corresponding to the second conductive plate CP2 with a smaller width can be set to be in the same layer as the second conductive plate CP2. At this time, mutual capacitance will be generated between the second conductive plate CP2 and the third conductive bridge CB3. In order to prevent the capacitance compensation from being too large, a second dummy plate DP2 (such as Figure 4B Similarly, a fourth dummy board DP4 is provided between the fourth conductive plate CP4 and the third auxiliary conductive bridge CB32. In one embodiment, the second dummy board DP2 may be provided to fill the space between the third conductive bridge CB3 and the second conductive plate CP2 as much as possible, so as to reduce the in-plane capacitance of the same layer while preventing interference and achieving a light shielding effect.

[0176] like Figure 4A As shown, the touch control structure of the embodiment of the present disclosure further includes a first dummy board DP1 and a third dummy board DP3. On the orthographic projection of the touch control structure, the first dummy board DP1 is between the first conductive board CP1 and the first conductive bridge CB1, and the third dummy board DP3 is between the third conductive board CP2 and the second conductive bridge CB2. The first dummy board DP1 and the third dummy board DP3 can prevent signal interference between the various metal patterns and play a light shielding role.

[0177] In addition, if Figure 4AAs shown, the touch structure of the present disclosure also includes a guard ring PR, which surrounds the periphery of the window area, which can be used to shield light and prevent light from entering the display panel from the window area WR. Various formats can be implemented to manufacture the protective environment PR. In one example, the guard ring PR has an overall structure (e.g., a complete ring structure) that substantially surrounds the periphery of the window area WR. In another example, the guard ring PR may also include a plurality of light-shielding ring blocks that are spaced apart from each other and surround a plurality of portions of the periphery of the window area WR, that is, a plurality of light-shielding ring blocks have small ports between them, so that static electricity can be released. The first conductive plate CP1, the second conductive plate CP2, the third conductive plate CP3 and the fourth conductive plate CP4 are, for example, arc-shaped, respectively, and extend approximately around the first part P1, the second part P2, the third part P3 and the fourth part P4 of the window area in the orthographic projection direction; the first conductive bridge CB1, the second conductive bridge CB2, the third conductive bridge CB3 and the third auxiliary conductive bridge CB32 are, for example, arc-shaped, respectively, and further, for example, fan rings, respectively, and also extend approximately around the first part P1, the second part P2, the third part P3 and the fourth part P4 of the window area; the first dummy plate DP1, the second dummy plate DP2, the third dummy plate DP3 and the fourth dummy plate DP4 are, for example, arc-shaped, respectively, and also extend approximately around the first part P1, the second part P2, the third part P3 and the fourth part P4 of the window area. These arc-shaped metal patterns can be concentric or non-concentric. The present disclosure does not limit this.

[0178] like Figure 4A As shown, in the window area WR, the touch structure includes a plurality of metal patterns such as a guard ring PR, a first conductive bridge CB1, a second conductive bridge CB2, a third conductive bridge CB3 and a third auxiliary conductive bridge CB32, a first dummy board DP1, a second dummy board DP2, a third dummy board DP3 and a fourth dummy board DP4, a first conductive board CP1, a second conductive board CP2, a third conductive board CP3 and a fourth conductive board CP4 from the inside to the outside. In this embodiment, these metal patterns can be set as fan rings, and further, these fan rings can even be set to be concentric (for example, the center of a circle when the orthographic projection of the window area WR is a circle), so that these metal patterns can be closely laid out, and capacitance compensation can be easily achieved and over-compensation can be prevented.

[0179] Specifically, Figure 4CAs shown, the touch control structure of the embodiment of the present disclosure includes a buffer layer BUF, a touch insulating layer TI on the buffer layer BUF, a second window grid block MB2 and a first window grid block MB1 located on a side of the touch insulating layer TI away from the buffer layer BUF, and a protective layer OC located on a side of the touch insulating layer TI away from the buffer layer BUF and covering the first window grid block MB1, the second window grid block MB2, the first conductive plate CP1, the second conductive plate CP2 and the third conductive bridge CB3. Figure 4C As shown, the touch structure of the embodiment of the present disclosure includes two metal layers, a first metal layer TMA, which includes a guard ring PR and a first conductive bridge CB1; a second metal layer TMB, which includes a second conductive plate CP2 and a first conductive plate CP1; and the first conductive bridge CB1 and the second conductive plate CP2 are directly connected together through a first via V1.

[0180] As mentioned above, in Figures 1 to 4C In the embodiment shown, except for the first conductive bridge CB1, the second conductive bridge CB2 and the guard ring PR, the other metal patterns are all on the touch insulation layer TI, that is, on the second metal layer TMB. In order to reduce impedance and improve touch detection reliability, the resistance of the second metal layer TMB can be selected to be smaller than the resistance of the first metal layer TMA.

[0181] The above embodiment provides a relatively simple structure, in which the window area WR is opened in the middle of four window grid blocks, so there is only one cross-window row Rwc and one cross-column row Cwc in the entire touch structure. However, the present disclosure is not limited thereto.

[0182] Figure 5 , Fig. 6A and Figure 6B FIG. 2 shows a touch control structure of an embodiment of the present disclosure. Figure 5 As shown, the window region WR of the touch structure spans across two adjacent rows of first grid electrodes TE1 and spans across a column of second grid electrodes TE2. That is, the touch structure of this embodiment includes a first cross-window row Rwc1, a second cross-window row Rwc2, and a cross-window column Cwc.

[0183] like Figure 5 As shown, most of the window region WR is in the first cross-window row Rwc1 and the cross-window column Cwc, while a small part is in the second cross-window row Rwc2.

[0184] Similar to Figure 2 A to Figure 4C In the embodiment shown, Figure 6BIn the illustrated embodiment, the touch structure includes a first window grid block MB1, a first conductive plate CP1 directly connected to the first window grid block MB1, a third window grid block MB3, a third conductive plate CP3 directly connected to the third window grid block MB3, a second window grid block MB2, and a second conductive plate CP2 directly connected to the second window grid block MB2. The first window grid block MB1, the second window grid block MB2, and the third window grid block MB3 have large pattern deletions due to the window region WR, so for the first window grid block MB1, the second window grid block MB2, and the third window grid block MB3, large first conductive plates CP1, second conductive plates CP2, and third conductive plates CP3 are used to compensate for the pattern deletions. Furthermore, relative to the second window grid block MB2, the pattern deletions of the first window grid block MB1 and the third window grid block MB3 are larger, so the widths of the first conductive plate CP1 and the third conductive plate CP3 used to compensate for the pattern deletions are greater than the width of the second conductive plate CP2. Similar to Figure 4A In the illustrated embodiment, the first conductive plate CP1, the second conductive plate CP2 and the third conductive plate CP3 may be arranged in an arc shape, further may be arranged in a fan ring shape, and further may be arranged in a concentric fan ring shape.

[0185] and Figures 2 to 4A Similar to the embodiment shown, Figure 6B The touch control structure shown also includes a third conductive bridge CB3 connecting the first conductive plate CP1 and the third conductive plate CP3; a first conductive bridge CB1 and a second conductive bridge CB2 respectively leading out the first end and the second end of the second conductive plate CP2 to be electrically connected to the grid line on the opposite side of the window area WR in the cross-window column Cwc. The first conductive bridge CB1 and the second conductive bridge CB2 constitute a dual Tx channel of the second conductive plate CP2, which can easily avoid the risk of circuit breakage. Figures 2 to 4A Similar to the embodiment shown, Figure 6B In the touch structure of the illustrated embodiment, the first conductive bridge CB1 and the second conductive bridge CB2 are arranged in different layers from the first conductive plate CP1, the second conductive plate CP2 and the third conductive plate CP3 to avoid excessive capacitance compensation caused by mutual capacitance with the first conductive plate CP1 and the second conductive plate CP2.

[0186] Figure 8B Shows Figure 6B FIG. 1 is an enlarged schematic diagram of the upper portion of the touch structure shown in FIG. Figure 6BAs shown, in the touch structure of the present disclosure, for different first window grid blocks MB1, second window grid blocks MB2 and third window grid blocks MB3, relatively large first conductive plates CP1, second conductive plates CP2 and third conductive plates CP3 directly connected thereto are respectively provided. Among them, the width of the first conductive plate CP1 used to compensate for the larger pattern loss in the third direction D3 is greater than the width of the second conductive plate CP2 used to compensate for the smaller pattern loss in the fourth direction D4. For the second conductive plate CP2, its two ends are respectively connected to the first conductive bridge CB1 and the second conductive bridge CB2, and the first conductive bridge CB1 and the second conductive bridge CB2 as dual Tx channels can reduce the risk of circuit breakage. In addition, as Fig.9A and Fig. 9B It can also be seen that the first conductive bridge CB1 and the second conductive bridge CB2 are arranged in the first metal layer TMA as a TMA dual Tx channel, and the second window grid block MB2 disconnected in the cross-window column Cwc is connected to the fourth window grid block MB4 opposite to the second grid electrode TE2 in the same column. Specifically, the dual Tx channel of the second metal layer TMA as the first conductive bridge CB1 and the second conductive bridge CB2 leads the second conductive plate CP2 to the second metal layer TMA through the first via hole V1 and the second via hole V2 in the touch insulation layer TI. Specifically, as Fig.9A and 9B , Fig.10 As shown, relative to the first conductive plate CP1, the second conductive plate CP2, the third conductive plate CP3, the first dummy plate DP1, the second dummy plate DP2, the third dummy plate DP3, and the third conductive bridge CB3 arranged in the second metal layer TMB, the first conductive bridge CB1, the second conductive bridge CB2, and the guard ring PR are located in the first metal layer TMA away from the surface of the protective layer OC relative to the second metal layer TMB, that is, through the first via hole V1 and the second via hole V2 at two opposite ends of the second conductive plate CP2, the two ends of the second conductive plate CP2 are respectively led to the first metal layer TMA to avoid over-compensation of capacitance caused by mutual capacitance with the first conductive plate CP1 and the third conductive plate CP3. For details, please refer to the following Fig. 6A Intercepted by the AA' line Fig.10 In addition, by connecting the disconnected second grid electrodes TE2 at both ends of the cross-window column Cwc together through a dual Tx channel, the risk of circuit breaking can be reduced.

[0187] Furthermore, if Figure 6BAs shown, the first conductive bridge CB1 includes a first connecting portion CB12 and a first trunk portion CB11, the first connecting portion CB12 is directly connected to the first end of the second conductive plate CP2, the first trunk portion CB11 is directly connected to the first connecting portion CB12 and extends along a first portion S1 of the periphery of the window region WR and is closer to the window region WR relative to the first conductive plate CP1; the second conductive bridge CB2 includes a second connecting portion CB22 and a second trunk portion CB21, the second connecting portion CB22 is directly connected to the second end of the second conductive plate CP2, the second trunk portion CB21 is directly connected to the second connecting portion CB22 and extends along a first portion S1 of the periphery of the window region WR The third portion S3 extends and is closer to the window region WR relative to the third conductive plate CP3; the third conductive bridge CB3 includes a third connection portion CB31, a fourth connection portion CB33 and a third main portion CB32 between the third connection portion CB31 and the fourth connection portion CB33, the third connection portion CB31 and the fourth connection portion CB33 are directly connected to the first end of the first conductive plate CP1 and the first end of the third conductive plate CP3 respectively, the third main portion CB32 is directly connected to the third connection portion CB31 and the fourth connection portion CB33 and extends along the second portion S2 of the periphery of the window region WR and is closer to the window region WR relative to the second conductive plate CP2. Further, as Figure 6B As shown, the first main trunk portion CB11 , the second main trunk portion CB21 and the third main trunk portion CB32 are all fan rings, and the orthographic projections of the first main trunk portion CB11 , the second main trunk portion CB21 and the third main trunk portion CB32 do not overlap.

[0188] Furthermore, if Fig. 6A and Figure 6B As shown, on the fourth side S4, i.e., in the lower part of the window region WR, due to the existence of the window region WR, relative to the window grid blocks of the first grid electrode TE1 and the second grid electrode TE2 not covered by the window region WR, the fourth window grid block MB4 lacks most of the grid lines, the fifth window grid block MB5 lacks a small part of the grid lines, and the sixth window grid block MB6 lacks a small part of the grid lines.

[0189] In order to compensate for the missing grid lines of the fourth window grid block MB4 , the fifth window grid block MB5 , and the sixth window grid block MB6 , the touch control structure of the embodiment of the present disclosure includes conductive plates positively correlated with the areas of the missing grid lines in these missing parts.

[0190] Specifically, Fig. 6A , Figure 6B , Figure 8CAs shown, the fourth window grid block MB4 is approximately located at the fourth side S4 of the window region WR opposite to the second side S2, and is divided into multiple independent parts by the window region WR. For example, the fourth window grid block MB4 includes at least one first window grid sub-block MB41, at least one second window grid sub-block MB42, MB44 and at least one third window grid sub-block MB43, MB45, MB46. The first window grid sub-block MB41 is adjacent to the window region WR and is located between at least one second window grid sub-block MB42, MB44 and at least one third window grid sub-block MB43, MB45, MB46. At least one second window grid sub-block MB42, MB44 is closer to the first window grid sub-block MB41. The first window grid block MB1 is closer to the third window grid block MB3, and at least one third window grid block MB43, MB45, and MB46 is closer to the third window grid block MB3 relative to the first window grid block MB41; for the first window grid block MB41, a first conductive sub-plate CP41 is provided, which is directly connected to a plurality of grid lines of the first window grid sub-block MB41 of the fourth window grid block MB4, and extends along the fourth portion P4 of the periphery of the window region WR; in order to connect the window grid blocks at both ends of the cross-window column Cwc, for the fourth window grid block MB4, two touch signal transmission channels are also provided: a fourth conductive bridge CB4 and a fifth conductive bridge CB5, to respectively establish connections with the first conductive bridge CB1 and the second conductive bridge CB2. Specifically, the fourth conductive bridge CB4 is directly connected to the first end of the first conductive sub-plate CP41, and the fifth conductive bridge CB5 is directly connected to the second end of the first conductive sub-plate CP41.

[0191] For at least one second window grid sub-block MB42, MB44, corresponding second conductive sub-plates CP42, CP44 are respectively provided, which are respectively directly connected to a plurality of grid lines of at least one second window grid sub-block MB42, MB44 of the fourth window grid block MB4, and extend along the fourth portion P4 of the periphery of the window region WR. In order to establish a connection with the first conductive bridge CB1, a sixth conductive bridge CB6 is further provided on one side of the farthest second conductive sub-plate CP44 farthest from the first conductive sub-plate CP41 among the at least one second conductive sub-plate CP42, CP44, which is close to the first window grid block MB1, and which is directly connected to the farthest second conductive sub-plate CP44.

[0192] like Figure 6B The touch control structure of the embodiment shown includes three third window grid sub-blocks MB43, MB45, and MB46, but the present disclosure is not limited thereto, which depends on the location where the window area WR is set. Figure 7 The touch control structure of the embodiment shown includes only one window grid sub-block MB43. Figure 6BIn the touch structure shown in FIG. 1 , for the third window grid sub-blocks MB3, MB45, and MB46, third conductive sub-plates CP43, CP45, and CP46 are provided, which are directly connected to a plurality of grid lines of the third window grid sub-blocks MB43, MB45, and MB46 of the fourth window grid block MB4, respectively, and extend along the fourth portion P4 of the periphery of the window region WR. In order to establish a connection with the second conductive bridge CB2, a seventh conductive bridge CB7 is further provided on one side of the third conductive sub-plate CP3 close to the third window grid sub-blocks MB43, MB45, and MB46, which is connected to the third conductive sub-plates CP43, CP45, and CP46, for example, in the example shown in FIG. Figure 6B In the illustrated embodiment, the seventh conductive bridge CB7 is directly connected to the farthest third conductive sub-plate CP46 which is the farthest from the first conductive sub-plate CP41 among the third conductive sub-plates CP43 , CP45 , and CP46 .

[0193] In this embodiment, a first conductive sub-plate CP41, at least one second conductive sub-plate CP42, CP44 and at least one third conductive sub-plate CP43, CP45, CP46 are provided for compensating for the missing metal grid pattern for the fourth window grid block MB4 in the cross-window column Cwc, which is missing most of the metal grid pattern. In order to construct a touch signal transmission path with the second window grid block MB2 in the cross-window column Cwc, the first conductive sub-plate CP41, at least one second conductive sub-plate CP42, CP44 and at least one third conductive sub-plate CP43, CP45, CP46 are connected to the second conductive plate CP2 of the second window grid block MB2 through the fourth conductive bridge CB4, the fifth conductive bridge CB5, the sixth conductive bridge CB6 and the seventh conductive bridge CB7, thereby forming a touch signal transmission path across the window column Cwc.

[0194] In this embodiment, at least a first conductive sub-plate CP41 is provided for the fourth window grid block MB4, which is approximately located on the fourth side S4 of the window region WR opposite to the second side S2, and is directly connected to most of the grid lines of the fourth window grid block MB4; at least one second conductive sub-plate CP42, CP44, which is approximately located on the fourth side S4 of the window region WR close to the first side S1, and is directly connected only to the grid lines of the finger-shaped grid sub-blocks of the fourth window grid block MB4; at least one third conductive sub-plate CP43, CP45, CP46, which is approximately located on the fourth side S4 of the window region WR close to the third side S3, and is similar to at least one second conductive sub-plate CP2, CP4, and is directly connected to the grid lines of the finger-shaped grid sub-blocks of the fourth window grid block MB4, respectively.

[0195] like Fig. 6A and Figure 6BAs shown, due to the existence of the window area WR, the fourth window grid block MB4 is missing most of the grid lines, that is, the area of ​​the fourth window grid block MB4 is less than 1 / 2 of the area of ​​the second non-window grid block NWB2. Therefore, in order to compensate for these missing grid lines, when the fourth window grid block MB4 has a limited extension length along the periphery of the window area WR, the first conductive sub-plate CP41 is set as a wider metal pattern, that is, for the missing grid lines, a larger compensation pattern is set for the fourth window grid block MB4 to compensate for the missing grid lines. For the missing grid lines of the finger-shaped grid sub-blocks of the fourth window grid block MB4, the entire second conductive sub-plates CP42 and CP4, and the third conductive sub-plates CP43, CP45, and CP46 are also set as compensation metal patterns.

[0196] like Fig. 6A and Figure 6B As shown, on the fourth side S4 of the window area WR, the touch structure also includes a fourth conductive bridge CB4 and a fifth conductive bridge CB5 directly connected to the two ends of the first conductive sub-plate CP41, and then finally connected to the first conductive bridge CB1 and the second conductive bridge CB2 through other metal patterns to form a dual Tx channel on the cross-window column Cwc to reduce the risk of short circuit.

[0197] Specifically, Figure 6B As shown, the farthest second conductive sub-plate CP44 is connected to the second end of the first conductive bridge CB1 through the sixth conductive bridge CB6. For example, the sixth conductive bridge CB6 and the first conductive bridge CB1 can be directly connected together through the third via V3 formed in the touch insulating layer TI; the farthest third conductive sub-plate CP46 is connected to the second end of the second conductive bridge CB2 through the seventh conductive bridge CB7. For example, the seventh conductive bridge CB7 and the second conductive bridge CB2 can be directly connected together through the fourth via V4 formed in the touch insulating layer TI.

[0198] For example, Figure 6BAs shown, the first end of the sixth conductive bridge CB6 is connected to the second end of the farthest second conductive sub-board CP44; the first end of the seventh conductive bridge CB7 is connected to the second end of the farthest third conductive sub-board CP46; the second end of the sixth conductive bridge CB6 is connected to the second end of the first conductive bridge CB1 through the third via V3 extending through the touch insulating layer TI; the second end of the seventh conductive bridge CB7 is connected to the second end of the second conductive bridge CB2 through the fourth via V4 extending through the touch insulating layer TI. Further, in this embodiment, the orthographic projection of the third via V3 on the touch insulating layer TI overlaps with the orthographic projection of the second end of the first conductive bridge CB1 on the touch insulating layer TI; the orthographic projection of the fourth via V4 on the touch insulating layer TI overlaps with the orthographic projection of the second end of the second conductive bridge CB2 on the touch insulating layer TI; the sixth conductive bridge CB6 and the seventh conductive bridge CB7 are in the second metal layer TMB. In this embodiment, when constructing the dual Tx channels forming the touch signal path outside the window area WR, as shown in FIG. Figure 6B As shown, the first trunk CB11 of the first conductive bridge CB1 extends along the first side S1 of the window region WR and is closer to the window region WR than the first conductive plate CP1. In the Tx channel, the first conductive bridge CB1 is located in the first metal layer TMA, and the second end of the first trunk CB11 touches the third via hole V3 of the insulating layer TI (see Fig. 9C and along Fig. 6A BB' intercepted Fig.11 ) is connected to the second end of the sixth conductive bridge CB6. In this embodiment, the sixth conductive bridge CB6 is in the second metal layer TMB, so Fig. 9C and Fig.11 As shown, the Tx channel switches from the first metal layer TMA to the second metal layer TMB at the third via hole V3; similarly, as Figure 6B As shown, the second trunk CB21 of the second conductive bridge CB2 extends along the third side S3 of the window region WR and is closer to the window region WR than the third conductive plate CP3. On the Tx channel, the second conductive bridge CB2 is located in the first metal layer TMA, and the second end of the second trunk CB21 thereof passes through the fourth via hole V4 (see FIG. Fig.9D ) is connected to the second end of the seventh conductive bridge CB7. In this embodiment, the seventh conductive bridge CB7 is in the second metal layer TMB, so Fig.9D As shown, the Tx channel is switched from the first metal layer TMA to the second metal layer TMB at the fourth via hole V4.

[0199] Furthermore, if Fig.12As shown, in this embodiment, the touch structure may also include a third auxiliary conductive bridge CB32, which includes a first auxiliary connection part CB321, a second auxiliary connection part CB323 and a first auxiliary trunk part CB322 connected between the first auxiliary connection part CB321 and the second auxiliary connection part CB323, the first auxiliary trunk part CB322 extending along the fourth portion P4 of the periphery of the window area WR and closer to the window area WR relative to the first conductive sub-plate CP41; the first end of the first auxiliary connection part CB321 is directly connected to the second end of the first conductive plate CP1 by extending through the fifth via V5 in the touch insulating layer TI, and the second end of the first auxiliary connection part CB321 is directly connected to the first end of the first auxiliary trunk part CB322; and the first end of the second auxiliary connection part CB323 is directly connected to the second end of the third conductive plate CP3 by extending through the sixth via V6 in the touch insulating layer TI, and the second end of the second auxiliary connection part CB323 is directly connected to the second end of the first auxiliary trunk part CB322; and the third auxiliary conductive bridge CB32 is in the first metal layer TMA. As shown in FIG. Fig.12 As shown, the third auxiliary conductive bridge CB32 directly connects the second end of the first conductive plate CP1 and the second end of the third conductive plate CP3 together, thereby forming a dual Rx channel in the row direction together with the third conductive bridge CB3, thereby constructing a dual-channel touch signal transmission path, thereby reducing the risk of circuit breaking.

[0200] and Fig.12 The embodiment shown is different. Fig.13 In the illustrated embodiment, in the cross-window column Cwc, the third via V3' for transforming the Tx channel from the first metal layer TMA to the second metal layer TMB is arranged at the first end of the sixth conductive bridge CB6', i.e., the end connected to the farthest second conductive sub-board CP44. At this time, the orthographic projection of the third via V3' on the touch insulating layer is far away from the window area WR relative to the first main body CB11 of the first conductive bridge CB1, and the sixth conductive bridge CB6' is arranged in the first metal layer TMA.

[0201] Specifically, Fig.13As shown, the first end of the sixth conductive bridge CB6' is connected to the second end of the farthest second conductive sub-board CP44 through the third via V3' extending through the touch insulating layer TI; the first end of the seventh conductive bridge CP7' is connected to the second end of the farthest third conductive sub-board CP46 through the fourth via V4' extending through the touch insulating layer TI; the second end of the sixth conductive bridge CB6' is connected to the second end of the first conductive bridge CB1; the second end of the seventh conductive bridge CB7' is connected to the second end of the second conductive bridge CB2. In this embodiment, the orthographic projection of the third via V3' on the touch insulating layer TI overlaps with the orthographic projection of the second end of the farthest second conductive sub-board CP44 on the touch insulating layer TI; the orthographic projection of the fourth via V4' on the touch insulating layer TI overlaps with the orthographic projection of the second end of the farthest third conductive sub-board CP46 on the touch insulating layer TI; at this time, the sixth conductive bridge CB6' and the seventh conductive bridge CB7' are in the first metal layer TMA.

[0202] Furthermore, if Fig.13 As shown, the touch structure also includes a third auxiliary conductive bridge CB32', which includes a first auxiliary connection part CB321', a second auxiliary connection part CB323' and a first auxiliary trunk part CB322' connected between the first auxiliary connection part CB321' and the second auxiliary connection part CB323', the first auxiliary trunk part CB322' extends along the fourth portion P4 of the periphery of the window area WR and is closer to the window area WR relative to the first conductive sub-plate CP41; the first end of the first auxiliary connection part CB321' is directly connected to the second end of the first conductive plate CP1, the second end of the first auxiliary connection part CB321' is directly connected to the first end of the first auxiliary trunk part CB322', the first end of the second auxiliary connection part CB323' is directly connected to the second end of the third conductive plate CP3, and the second end of the second auxiliary connection part CB323' is directly connected to the second end of the first auxiliary trunk part CB322'; and the third auxiliary conductive bridge CB32' is in the second metal layer TMB. Fig.13 As shown, the third auxiliary conductive bridge CB32' directly connects the second end of the first conductive plate CP1 and the second end of the third conductive plate CP3 together, thereby forming a dual Rx channel in the row direction together with the third conductive bridge CB3, thereby constructing a dual-channel touch signal transmission path, thereby reducing the risk of circuit breaking.

[0203] As described above, the first conductive bridge CB1 and the second conductive bridge CB2 are arranged in the first metal layer TMA below the touch insulating layer TI to avoid over-compensation of capacitance, wherein the first via hole V1 and the second via hole V2 formed in the touch insulating layer TI are used to form a signal path for the second conductive plate CP2 on the cross window column Cwc. Figure 6B and Figure 8CAs shown, due to the existence of the window area WR, the capacitance compensation of the fourth side S4 is relatively complicated. This is because Figure 6B and Figure 8C In the embodiment shown in FIG. 1 , the fourth side S4 of the window region WR occupies a position where a row of first grid electrodes TE1 and a column of second grid electrodes TE2 intersect. Figure 6B As shown, the fourth side S4 of the periphery of the window region WR alternately contacts the grid lines of the first grid electrode TE1 and the second grid electrode TE2, so correspondingly, it is necessary to set alternate compensation conductive plates for the missing grid lines of the first grid electrode TE1 and compensation conductive plates for the missing grid lines of the second grid electrode TE2. In this case, it is difficult to repeatedly form the first via hole V1, the second via hole V2, the third via hole V3 and the fourth via hole V4 similar to the first conductive bridge CB1 and the second conductive bridge CB2. Therefore, on the fourth side S4 of the window region WR, the various compensation metal patterns included in the touch control structure for compensating for the missing grid lines of the first grid electrode TE1 and the second grid electrode TE2 can all be set in the second metal layer TMB.

[0204] Specifically, 9A to 9E As shown, the metal patterns provided for the missing grid lines of the first grid electrode TE1 and the second grid electrode TE2 are all provided in the first metal layer TMB.

[0205] Reference Fig. 6A , Figure 6B , Figure 8C , 9A to 9E As shown, at least one cross-window row of the touch structure of the present disclosure also includes a second cross-window row Rwc2, which is adjacent to the first cross-window row Rwc1, and the second cross-window row Rwc2 includes: a fifth window grid block MB5, which is adjacent to the window area WR and is located on the same side as the second window grid sub-blocks MB42 and MB44, and includes at least one fifth window grid sub-block. In this embodiment, these fifth window grid sub-blocks are finger-shaped grid sub-blocks and cross with the second window sub-blocks MB42 and MB44 and are alternately located on the fourth side S4 of the window area; at least one fifth window grid sub-block is arranged in a one-to-one correspondence with the at least one fifth window grid sub-block. Conductive sub-plates CP51 and CP52 are directly connected to multiple grid lines of multiple finger-shaped grid sub-blocks of the fifth window grid block MB5, and extend along the fourth portion P4 of the periphery of the window region WR. Accordingly, at least one fifth conductive sub-plate CP51 and CP52 and at least one second conductive sub-plate CP42 and CP44 are arranged to extend alternately along the fourth portion P4 of the periphery of the window region WR. A sixth window grid block MB6 is adjacent to the window region WR and is located on the same side as the third window grid sub-blocks MB43, MB45, and MB46. When the touch structure includes multiple third window grid sub-blocks (such as Figure 6B As shown, the touch structure includes three third window grid sub-blocks MB43, MB45, and MB46, and the multiple finger-shaped grid sub-blocks included in the sixth window grid block MB6 are alternately located on the fourth side S4 of the window area WR in the same way as the multiple third window grid sub-blocks; at least one sixth conductive sub-plate CP61, CP62, and CP63, which are directly connected to the multiple grid lines of the multiple finger-shaped grid sub-blocks of the sixth window grid block MB6 and extend along the fourth part P4 of the periphery of the window area WR, and the fifth window grid block MB5 and the sixth window grid block MB6 are directly connected through the electrode bridge EB41 on the side of the window area WR away from the first cross-window row Rwc1.

[0206] Specifically, Figure 6B and Figure 8C As shown, in the extension direction of the fourth portion P4 along the periphery of the window area WR, the fifth conductive sub-plate CP52 is between the second conductive sub-plate CP42 and the first conductive sub-plate CP41, and the fifth conductive sub-plate CP51 is between the second conductive sub-plate CP42 and the second conductive sub-plate CP44; and the sixth conductive sub-plate CP63 is between the first conductive sub-plate CP41 and the third conductive sub-plate CP43, the sixth conductive sub-plate CP62 is between the third conductive sub-plate CP43 and the third conductive sub-plate CP45, and the sixth conductive sub-plate CP61 is between the third conductive sub-plate CP45 and the third conductive sub-plate CP46. Figure 6B In the illustrated embodiment, the touch structure includes only two second conductive sub-plates CP42 and CP44 on one side of the first conductive sub-plate CP41 close to the first conductive plate CP1. For the sake of convenience, the second conductive sub-plate CP42 close to the first conductive sub-plate CP41 may be referred to as the nearest second conductive sub-plate CP42, and the second conductive sub-plate CP44 far away from the first conductive sub-plate CP41 and closer to the first conductive plate CP1 relative to the nearest second conductive sub-plate CP42 may be referred to as the farthest second conductive sub-plate CP44; similarly, for the third conductive sub-plates CP43, CP45, and CP46, the third conductive sub-plate CP43 close to the first conductive sub-plate CP41 may be referred to as the nearest third conductive sub-plate CP43, and the third conductive sub-plate CP46 farthest from the first conductive sub-plate CP41 and closest to the third conductive plate CP3 relative to the nearest third conductive sub-plate CP43 may be referred to as the farthest third conductive sub-plate CP46.

[0207] As shown in the figure, the metal mesh patterns connected to the fifth conductive sub-plates CP52, CP51 and the sixth conductive sub-plates CP63, CP62, CP61 are respectively finger-shaped mesh sub-blocks. That is, the finger-shaped mesh sub-blocks on the fifth window mesh block MB5 and the sixth mesh block MB6 only lack a small part of the mesh pattern. Figure 6BIt can be seen that the fifth conductive sub-plates CP52 and CP51 for compensating the missing pattern of the fifth window grid block MB5 are relatively small, and the sixth conductive sub-plates CP61, CP62, and CP63 for compensating the missing pattern of the sixth window grid block MB6 are also relatively small. Figure 6B As shown, the width of each of at least one fifth conductive sub-plate CP51, CP52 along the direction perpendicular to the interface between the fifth conductive sub-plate and the corresponding finger-shaped grid sub-block is substantially equal to the width of each of at least one sixth conductive sub-plate CP61, CP62, CP63 along the direction perpendicular to the interface between the sixth conductive sub-plate and the corresponding finger-shaped grid sub-block. In this way, the manufacturing process can be simplified, and it can be easily determined whether the compensation is appropriate.

[0208] like Fig. 6A and Figure 6B As shown, due to the existence of the window area WR, the fourth window grid block MB4 is missing most of the grid lines, that is, only the first window grid sub-block MB41, the second window grid sub-block MB42, MB44, the third window grid sub-block MB43, MB45, MB46 of the fourth window grid block of the finger-shaped grid sub-block are left. Therefore, in order to compensate for the larger pattern loss, a wider first conductive sub-plate CP41 is set for the first window grid sub-block MB41. For example, when the first conductive sub-plate CP41 is a fan ring, its width along the direction perpendicular to the interface between the first conductive sub-plate CP41 and the first window grid sub-block MB41 can be set to between 140μm and 160μm, for example, 150μm.

[0209] like Figure 6B As shown, the first end of the first conductive sub-plate CP41 is connected to the second end of the first conductive bridge CB1 opposite to the first end through the fourth conductive bridge CB4, the second conductive sub-plate CP42, CP44 and the sixth conductive bridge CB6; the second end of the first conductive sub-plate CP41 is connected to the second end of the second conductive bridge CB2 opposite to the first end through the fifth conductive bridge CB5, the third conductive sub-plate CP43, CP45, CP46 and the seventh conductive bridge CB7. Based on this, in the cross-window column Cwc, the dual-channel first conductive bridge CB1 and the second conductive bridge CB2, the dual-channel fourth conductive bridge CB4 and the fifth conductive bridge CB5, the dual-channel sixth conductive bridge CB6 and the seventh conductive bridge CB7 constitute a dual Tx channel in the cross-window column Cwc, thereby greatly avoiding the risk of circuit breakage. The above structure constitutes the fourth conductive structure for the fourth window grid block MB4, which constructs a touch signal transmission path between the second window grid block MB2 and the fourth conductive grid block MB4 in the direction of the cross-window column Cwc.

[0210] like Figure 6BAs shown in FIG. 1 , in addition to forming a guard ring PR near one side of the window region WR, each metal pattern of the touch structure at the lower part of the window region WR (i.e., in the second cross-window row Rwc2) is in the second metal layer TMB. For example, both the Rx channel of the first grid electrode TE1 and the Tx channel of the second grid electrode TE2 are arranged in the second metal layer TMB, while the other dummy plates (in Figure 4B In this area, since the window grid block structure connected to each conductive plate used to compensate for the missing grid line is relatively complex, it is difficult to set vias as in the case of the relatively simple conductive plate structure of the first cross-window row Rwc1. Figure 6B As shown, when each conductive plate is provided for the second cross-window row Rwc2 to compensate for the missing grid lines, the first conductive bridge CB1 and the second conductive bridge CB2 are guided to the sixth conductive bridge CB6 and the seventh conductive bridge CB7 through the third via V3 and the fourth via V4 respectively.

[0211] Specifically, the fifth conductive sub-plate CP52, CP51, the sixth conductive sub-plate CP61, CP62, CP63, the first conductive sub-plate CP41, the second conductive sub-plate CP42, CP44, the third conductive sub-plate CP43, CP45, CP46, the fourth conductive bridge CB4, the fifth conductive bridge CB5, the sixth conductive bridge CB6 and the seventh conductive bridge CB7 are in the same layer (for example, the second metal layer TMB) as the first conductive plate CP1, the second conductive plate CP2 and the third conductive plate CP3; the sixth conductive bridge CB6 is connected to the second end of the first conductive bridge CB1 through the third via V3 extending through the touch insulating layer TI; the seventh conductive bridge CB7 is connected to the second end of the second conductive bridge CB2 through the fourth via V4 extending through the touch insulating layer TI.

[0212] like Figure 6B As shown, since the fourth window grid block MB4 lacks most of the grid patterns, in order to compensate for the missing grid patterns, the fourth conductive structure set for the fourth window grid block MB4 includes a first conductive sub-plate CP41, a second conductive sub-plate CP42, CP44, a third conductive sub-plate CP43, CP45, and CP46, and these conductive sub-plates are directly connected to multiple grid lines of the fourth window grid block MB4.

[0213] However, the present disclosure is not limited thereto, and depending on the different locations of the window region WR, simply providing a conductive plate directly connected to multiple grid lines of the window grid block may not be sufficient to compensate for the missing grid pattern. Figure 7In the setting of the window area WR shown, the touch structure includes only one third window grid sub-block MB43 on the fourth side S4 of the window area. In this case, the fourth conductive structure may also include at least one auxiliary conductive sub-plate CP45', CP46', which is not connected to the metal pattern of the fourth window grid block MB4, but is connected to the first conductive sub-plate CP41, the second conductive sub-plate CP42, CP44, and the third conductive sub-plate CP43, and also extends along the fourth part P4 of the periphery of the window area WR, and is used to assist the first conductive sub-plate CP41, the second conductive sub-plate CP42, CP44, and the third conductive sub-plate CP43 to compensate for the missing grid pattern and construct a touch signal transmission path in the column direction.

[0214] Specifically, Figure 7 As shown, the auxiliary conductive sub-plates CP45' and CP46' can be fan-arcs like the first conductive sub-plate CP41, the second conductive sub-plate CP42, CP44, and the third conductive sub-plate CP43. At the same time, in order to further simplify the preparation process and effectively calculate the compensation capacitance, the auxiliary conductive sub-plates CP45' and CP46' can be set as concentric fan-arcs with the first conductive sub-plate CP41, the second conductive sub-plate CP42, CP44, and the third conductive sub-plate CP43, that is, the center of the window area WR can be used as the center of each fan-arc. Furthermore, the widths of these fan-arcs can be set to be the same. As shown in FIG. Figure 7 As shown, in this embodiment, the auxiliary conductive sub-plates CP45', CP46' and the third conductive sub-plate CP43 are arranged on the same side, which mainly depends on the setting position of the window area WR. In this case, at the position where the auxiliary conductive sub-plates CP45', CP46' are arranged, there is no grid line of the fourth window grid block MB4, that is, the fourth window grid block MB4 is completely occupied by the window area WR at this position. However, as understood by those skilled in the art, the present disclosure is not limited to this. For example, when the window area WR moves toward the first window grid block MB1, the fourth window grid sub-block MB44 may be completely occupied by the window area WR.

For example, a circular ring with a cutout may be formed to release static electricity.

[0217] In the present disclosure, a dummy board in a "floating state" means that the dummy board is not connected or in contact with other components, and is disposed between two conductive boards or between a conductive board and a conductive bridge in the present disclosure to avoid excessive mutual capacitance between the two, resulting in transition compensation, etc. In addition, it can also play a role in shading.

[0218] In order to prevent signal interference between metal patterns and prevent the influence of light on the touch structure, such as Figure 6BAs shown, the touch structure may further include an eighth dummy board DP81, DP82, the eighth dummy board DP81, DP82 is in a floating state, and its orthographic projection on the touch insulating layer TI is located between the orthographic projection of the second conductive sub-board CP42, CPP44 on the touch insulating layer TI and the orthographic projection of the guard ring PR on the touch insulating layer TI; similarly, the touch structure may include a ninth dummy board DP9, DP10, DP11, the ninth dummy board DP9, DP10, DP11 is in a floating state, and its orthographic projection on the touch insulating layer TI is located between the orthographic projection of the third conductive sub-board CP43, CP45, CP46 on the touch insulating layer TI and the orthographic projection of the guard ring PR on the touch insulating layer TI.

In one embodiment, the guard ring PR is in the same layer as the first conductive bridge CB1 and the second conductive bridge CB2, that is, in the first metal layer TMA.

[0219] In addition, if Figure 7 As shown, for the auxiliary conductive sub-plates CP45' and CP46', the touch control structure of the present disclosure further includes tenth dummy plates DP10' and DP11'. Figure 7 The eighth dummy boards DP81 and DP82 are similar to the ninth dummy board DP9 , and the tenth dummy boards DP10 ′ and DP11 ′ are also arranged in the second metal layer TMB, which also play the role of preventing signal interference and shielding light.

[0220] exist Figure 6B and Figure 7 In the embodiment shown, as described above, the structure of the touch structure on the fourth side S4 is relatively complex because the window area WR spans two cross-window rows (ie, the first cross-window row Rwc1 and the second cross-window row Rwc2). Figure 6B and Figure 7 As shown, the fourth side S4 of the periphery of the window region WR alternately contacts multiple grid lines of the first grid electrode TE1 and the second grid electrode TE2, so correspondingly, compensation conductive plates for the missing grid lines of the first grid electrode TE1 and compensation conductive plates for the missing grid lines of the second grid electrode TE2 need to be alternately arranged.

[0221] Specifically, Figure 6BAs shown, on the side of the fourth part P4 along the periphery of the window area WR close to the first conductive plate CP1, the fourth conductive bridge CB4, the fifth conductive sub-plate CP52 and the fifth dummy plate DP52 therebetween, the second conductive sub-plate CP42 and the eighth dummy plate DP81 can be regarded as a first loop structure; the first intermediate connecting structure IM1, the fifth conductive sub-plate CP51 and the seventh dummy plate DP51 therebetween, the second conductive sub-plate CP44 and the eighth dummy plate DP82 can be regarded as a first loop structure, so the fourth conductive structure on the side close to the first conductive plate CP1 can be regarded as including two substantially identical first loop structures; on the side of the fourth part P4 along the periphery of the window area WR close to the third conductive plate CP3, the fifth conductive bridge CB5, the sixth conductive sub-plate CP63 and the sixth dummy plate DP63 therebetween, the third conductive sub-plate CP43 and the ninth dummy plate DP91 can be regarded as constituting a second loop structure; the second intermediate connecting structure IM2, the sixth conductive sub-plate CP62 and the second The eleventh dummy board DP62, the third conductive sub-board CP45 and the ninth dummy board DP92 therebetween can be regarded as constituting a second loop structure; the second intermediate connecting structure IM2, the sixth conductive sub-board CP61 and the eleventh dummy board DP61, the third conductive sub-board CP46 and the ninth dummy board DP93 therebetween can be regarded as constituting a second loop structure; therefore, on the second cross-window row Rwc, for the positions where the finger-shaped grid sub-blocks of the first electrode grid electrode TE1 and the second grid electrode TE2 intersect with each other, the touch structure includes at least two first loop structures in the direction from the first conductive sub-board CP41 to the first conductive plate CP1 along the fourth part P4 of the periphery of the window area WR; and the touch structure includes at least three second loop structures in the direction from the first conductive sub-board CP41 to the third conductive plate CP3 along the fourth part P4 of the periphery of the window area WR, so the required compensation pattern can be easily obtained, and the touch structure of the present disclosure can be prepared using a simple mask plate and process.

[0222] Similarly, if Figure 7As shown, on the side of the fourth part P4 along the periphery of the window area WR close to the first conductive plate CP1, the fourth conductive bridge CB4, the fifth conductive sub-plate CP52 and the fifth dummy plate DP52 therebetween, the second conductive sub-plate CP42 and the eighth dummy plate DP81 can be regarded as a first loop structure; the first intermediate connecting structure IM1, the fifth conductive sub-plate CP51 and the seventh dummy plate DP51 therebetween, the second conductive sub-plate CP44 and the eighth dummy plate DP82 can be regarded as a first loop structure, so the fourth conductive structure on the side close to the first conductive plate CP1 can be regarded as including two substantially identical first loop structures; on the side of the fourth part P4 along the periphery of the window area WR close to the third conductive plate CP3, the fifth conductive bridge CB5, the sixth conductive sub-plate CP63 and the sixth dummy plate DP63 therebetween, the third conductive sub-plate CP43 and the ninth dummy plate DP91 can be regarded as constituting a second loop structure; the second intermediate connecting structure IM2, the sixth conductive sub-plate CP62 and the seventh dummy plate DP51 therebetween The twelfth dummy board DP62', the auxiliary conductive sub-board CP45' and the tenth dummy board DP10 therebetween can be regarded as constituting a second loop structure; the second intermediate connecting structure IM2, the sixth conductive sub-board CP61 and the twelfth dummy board DP61', the auxiliary conductive sub-board CP46' and the tenth dummy board DP11 therebetween can be regarded as constituting a second loop structure; therefore, on the second cross-window row Rwc, for the positions where the finger-shaped grid sub-blocks of the first electrode grid electrode TE1 and the second grid electrode TE2 intersect with each other, the touch structure includes at least two first loop structures in the direction from the first conductive sub-board CP41 to the first conductive plate CP1 of the fourth part P4 along the periphery of the window area WR; and the touch structure includes at least three second loop structures in the direction from the first conductive sub-board CP41 to the third conductive plate CP3 of the fourth part P4 along the periphery of the window area WR, so the required compensation pattern can be easily obtained, and the touch structure of the present disclosure can be prepared using a simple mask plate and process.

[0223] like Figure 6BAs shown, in order to further increase the touch signal transmission path and thus fully realize compensation, the fourth conductive structure adopts a concave-convex structure on the fourth side S4 along the window area WR: the fourth conductive bridge CB4 and the fifth conductive bridge CB5 are directly connected to the two ends of the surface of the first conductive sub-plate CP41 on the side close to the window area through the fourth main stem CB42 and the fifth main stem CB52 respectively; the first intermediate connection structure IM1, the second intermediate connection structure IM2 and the third intermediate connection structure IM3 respectively include a terminal portion extending from a side close to the window area WR to a side away from the window area WR, And on the side away from the window area WR, they are respectively connected to the second conductive sub-board CP42, CP44 and the third conductive sub-board CP43, CP45, CP46; the second conductive sub-board CP42, CP44 and the third conductive sub-board CP43, CP45, CP46 again guide the fourth conductive structure to the side close to the window area WR through the conductive bridges (the sixth conductive bridge CB6 and the seventh conductive bridge CB7 respectively), thereby constructing a circular structure similar to the concave-convex structure on both sides of the first conductive sub-board CP1, so as to increase the touch signal transmission path to meet the compensation requirements. In addition, if Figure 6B As shown, the structure for compensating the missing pattern of the fifth window grid block MB5 and the sixth window grid block MB6 for the second cross-window row Rwc2 (the fifth conductive sub-plate CP51, CP52, the sixth conductive sub-plate CP61, CP62, CP63) can be set in the concave-convex structure to improve the mutual capacitance. In this process, over-compensation may occur. In this case, according to the simulation, a dummy plate (for example, the eighth dummy plate DP81, DP82, the ninth dummy plate DP91, DP92, DP3) can be set to avoid over-compensation.

[0224] Similarly, in Figure 7In the illustrated embodiment, in order to further increase the touch signal transmission path and thereby fully realize compensation, the fourth conductive structure adopts a concave-convex structure on the fourth side S4 along the window area WR: the fourth conductive bridge CB4 and the fifth conductive bridge CB5 are directly connected to the two ends of the surface of the first conductive sub-plate CP41 on the side close to the window area through the fourth main stem CB42 and the fifth main stem CB52 respectively; the first intermediate connection structure IM1, the second intermediate connection structure IM2 and the third intermediate connection structure IM3 respectively include a terminal portion extending from a side close to the window area WR to a side away from the window area WR, and at a side away from the window area WR, the terminal portion is connected to the first conductive sub-plate CP41. One side of the window area WR is respectively connected to the second conductive sub-board CP42, CP44, the third conductive sub-board CP43, the auxiliary conductive sub-board CP45', CP46'; the second conductive sub-board CP42, CP44, the third conductive sub-board CP43, the auxiliary conductive sub-board CP45', CP46' again guides the fourth conductive structure to the side close to the window area WR through the conductive bridges (the sixth conductive bridge CB6 and the seventh conductive bridge CB7 respectively), thereby constructing a circular structure similar to the concave-convex structure on both sides of the first conductive sub-board CP1, so as to increase the touch signal transmission path to meet the compensation requirements. In addition, as Figure 7 As shown, the structure for compensating the missing pattern of the fifth window grid block MB5 and the sixth window grid block MB6 for the second cross-window row Rwc2 (the fifth conductive sub-plate CP51, CP52, the sixth conductive sub-plate CP61, CP62, CP63) can be set in the concave-convex structure to improve the mutual capacitance. In this process, over-compensation may occur. In this case, according to the simulation, a dummy plate (for example, the eighth dummy plate DP81, DP82, the ninth dummy plate DP91, the tenth dummy plate DP10, DP11) can be set to avoid over-compensation.
