[0044] To make the above objects, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.
[0045] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one, or at least two. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the associated objects before and after are in an "or" relationship.
[0046] In a first aspect of the present application, a touch panel is proposed. The touch panel includes a touch area, and a first border area and a second border area that are oppositely arranged on both sides of the touch area along the row direction.
[0047] Referring to Figure 1 , Figure 1 , a schematic diagram of the positional relationship between a touch area and a border area is shown. The touch area refers to an area where a user can perform corresponding touch functions through touch operations. The border area is located around the touch area and is used to set corresponding traces. As Figure 1 shown, the area framed by the solid line is the touch area, and the touch area can be Figure 1The rectangle shown may also be of other shapes. The areas outlined by the dashed lines are border areas: a first border area and a second border area. The direction of the arrow is the row direction, and this row direction may be parallel to one side of the touch area. Along the row direction, the first border area and the second border area are located on opposite sides of the touch area, that is, the first border area, the touch area, and the second border area are arranged in sequence along the row direction. The border areas may be in contact with the touch area or may be separated from each other.
[0048] The touch panel includes: a substrate, and a plurality of first touch electrodes and a plurality of second touch electrodes provided on one side of the substrate. The first touch electrodes and the second touch electrodes are arranged separately from each other. The plurality of first touch electrodes are arranged in multiple rows, and two adjacent first touch electrodes in the same row are connected by a first connection portion. The plurality of second touch electrodes are arranged in multiple columns, and two adjacent second touch electrodes in the same column are connected by a second connection portion. The first connection portion and the second connection portion intersect with each other and are arranged in different layers.
[0049] Specifically, in this touch panel, the touch layer is located on one side of the substrate. The touch layer includes a plurality of touch electrode units arranged in an array. The touch electrode units are generally divided into two categories, namely driving electrodes Tx and sensing electrodes Rx, which are equivalent to the first touch electrodes and the second touch electrodes in the embodiments of the present application. In this embodiment, it may be that the first touch electrode is the driving electrode Tx and the second touch electrode is the sensing electrode Rx, or it may be that the first touch electrode is the sensing electrode Rx and the second touch electrode is the driving electrode Tx. It is not limited in this embodiment.
[0050] Referring to Figure 2 , Figure 2 shows a schematic diagram of the arrangement of touch electrodes. Figure 2 is a top view of the touch layer. As Figure 2 shown, a plurality of first touch electrodes 100 are arranged in multiple rows along the row direction, and two adjacent first touch electrodes 100 in the same row are connected by a first connection portion 101. A plurality of second touch electrodes 200 are arranged in multiple columns along the column direction, and two adjacent second touch electrodes 200 in the same column are connected by a second connection portion 201. The first touch electrodes 100 form a first touch layer, and the second touch electrodes 200 form a second touch layer, corresponding to the Figure 10The first touch layer 4 and the second touch layer 6 introduced above are arranged in different layers. The first touch electrode 100 and the second touch electrode 200 are separated from each other, not connected and insulated from each other. That is, in the orthographic projection on the substrate, the orthographic projection of the first touch electrode 100 does not overlap with the orthographic projection of the second touch electrode 200. The first touch electrode and the second touch electrode are arranged in a staggered manner. That is, viewed along the row direction, there is a row of second touch electrodes 200 between adjacent two rows of first touch electrodes 100; viewed along the column direction, there is a column of first touch electrodes 100 between adjacent two columns of second touch electrodes 200. The first connection portion 101 and the second connection portion 201 cross each other and are arranged in different layers, not in contact or connection. As Figure 2 shown, the second connection portion 201 can be located above the first connection portion 101, or the first connection portion 101 can be located above the second connection portion 201.
[0051] As Figure 2 shown, in the related art, the electrode array often adopts a centered filling method, and the size of the touch area is often not exactly equal to the size of the electrode array. When the area of the touch area is larger than the area of the electrode array, there are likely to be areas on the left and right sides of the touch area that are not filled by the electrode units (the first touch electrode or the second touch electrode) (such as Figure 2 the area where the ellipse drawn by the dotted line shown is located), and the touch effect in this edge area is not good. To solve this problem, the embodiments of the present application propose to improve the touch layer structure from two aspects: on the one hand, the touch electrodes are arranged close to the edge (that is, the centered filling method is not adopted), and on the other hand, a corresponding compensation structure is added in the area of the vacant electrode. The specific improvement methods are as follows:
[0052] Among them, multiple first touch electrodes in the same row include a first sub-touch electrode and a second sub-touch electrode. One of the first sub-touch electrode and the second sub-touch electrode is arranged close to the first border area, and the other is arranged close to the second border area. The multiple second touch electrodes include a third sub-touch electrode and a fourth sub-touch electrode. The third sub-touch electrode is arranged adjacent to the first sub-touch electrode, and the fourth sub-touch electrode is arranged adjacent to the second sub-touch electrode; and in the orthographic projection on the substrate, the area of the first sub-touch electrode is larger than the area of the second sub-touch electrode, and the area of the third sub-touch electrode is larger than the area of the fourth sub-touch electrode.
[0053] Referring to Figure 3 , Figure 3 shows a schematic layout diagram of the first touch electrode and the second touch electrode. As Figure 3As shown, multiple first touch electrodes 100 in the same row include a first sub-touch electrode 100a and a second sub-touch electrode 100b. Among them, the first sub-touch electrode 100a represents that on the basis of the second sub-touch electrode 100b, that is, the original touch electrode (such as Figure 2 the touch electrode shape shown), a compensation structure (such as Figure 3 the rectangular block structure shown) is added to the touch electrode. One of the first sub-touch electrode 100a and the second sub-touch electrode 100b is arranged close to the first border area, and the other is arranged close to the second border area. That is to say, the first sub-touch electrode 100a and the second sub-touch electrode 100b are the two first touch electrodes at both ends of each row of first touch electrodes. Moreover, one of the two first touch electrodes is arranged close to the first border area, indicating contact with the side edge of the touch area close to the first border area, and the other is arranged close to the second border area, indicating contact with the side edge of the touch area close to the second border area. Therefore, both ends of each row of first touch electrodes in the row direction can be in contact with the two side edge lines of the touch area.
[0054] Correspondingly, as Figure 3 shown, multiple second touch electrodes 200 include a third sub-touch electrode 200a and a fourth sub-touch electrode 200b. Among them, the third sub-touch electrode 200a represents that on the basis of the fourth sub-touch electrode 200b, that is, the original touch electrode (such as Figure 2 the touch electrode shape shown), a compensation structure (such as Figure 3 the rectangular block structure shown) is added to the touch electrode. Among them, the third sub-touch electrode 200a is arranged adjacent to the first sub-touch electrode 100a, and the fourth sub-touch electrode 200b is arranged adjacent to the second sub-touch electrode 100b. As Figure 3 shown, from the row direction, the first sub-touch electrode 100a and the second sub-touch electrode 100b are the two first touch electrodes at both ends of each row of first touch electrodes, and the third sub-touch electrode 200a and the fourth sub-touch electrode 200b are the two second touch electrodes within both ends of each row of second touch electrodes; from the column direction, among multiple columns of second touch electrodes, the third sub-touch electrode 200a and the fourth sub-touch electrode 200b are located in the outermost two columns of second touch electrodes closest to the first border area and the second border area. That is, in each row of second touch electrodes, one of the third sub-touch electrode 200a and the fourth sub-touch electrode 200b is arranged close to the first border area, indicating contact with the side edge of the touch area close to the first border area, and the other is arranged close to the second border area, indicating contact with the side edge of the touch area close to the second border area. Therefore, both ends of each row of second touch electrodes in the row direction can be in contact with the two side edge lines of the touch area.
[0055] According to Figure 2and Figure 3 It can be seen that, aiming at the problem that the pattern integrity in the existing touch panel is less than 100%, resulting in poor touch performance in the edge area of the unfilled electrode, the embodiment of the present application proposes not to adopt the centered filling method, but to add a compensation structure to the first touch electrode and the second touch electrode respectively in the touch electrode layer of the touch panel, so as to obtain the first touch sub-electrode in the first touch electrode and the third touch sub-electrode in the second touch electrode (in the orthographic projection on the substrate, the area of the first sub-touch electrode is larger than that of the second sub-touch electrode, and the area of the third sub-touch electrode is larger than that of the fourth sub-touch electrode). For multiple rows of the first touch electrodes and multiple rows of the second touch electrodes, one end is arranged close to the edge (that is, close to the edge of the touch area), and the other end can also be arranged close to the edge due to the added compensation structure (that is, close to the edge of the touch area). That is, one of the first sub-touch electrode and the second sub-touch electrode is arranged close to the first border area, and the other is arranged close to the second border area; one of the third sub-touch electrode and the fourth sub-touch electrode is arranged close to the first border area, and the other is arranged close to the second border area. Thus, by adding a corresponding compensation structure in the area where the touch electrode is not set, the pattern is completely filled in every corner of the touch area of the touch panel, and the problem of poor touch performance in the edge area of the panel is solved.
[0056] In a possible implementation manner, the shapes of the orthographic projections of the first sub-touch electrode and the second sub-touch electrode on the substrate are different, and the shapes of the third sub-touch electrode and the fourth sub-touch electrode are different.
[0057] Due to the fact that in the centered filling method of the electrode, it is difficult for the electrode pattern to fill the touch area by 100%, so that there are no touch electrodes in some areas (the edge areas on both the left and right sides) of the touch area, and thus the touch effect is not good. The embodiment of the present application proposes to add a compensation structure to some of the electrode units. The first touch sub-electrode 100a represents the touch electrode after adding a compensation structure (such as the rectangular block structure shown in Figure 2 ) on the basis of the second touch sub-electrode 100b, that is, the original touch electrode (such as the touch electrode shape shown in Figure 3 ); the third touch sub-electrode 200a represents the touch electrode after adding a compensation structure (such as the rectangular block structure shown in Figure 2 ) on the basis of the fourth touch sub-electrode 200b, that is, the original touch electrode (such as the touch electrode shape shown in Figure 3The touch electrodes after the rectangular block structure shown). Therefore, in the orthographic projection on the substrate, the area of the first sub-touch electrode 100a is larger than that of the second sub-touch electrode 100b, and the area of the third sub-touch electrode 200a is larger than that of the fourth sub-touch electrode 200b. Moreover, since the compensation structure is directly added on the basis of the original regular-shaped touch electrode shape, the orthographic projection shapes of the first sub-touch electrode 100a and the second sub-touch electrode 100b on the substrate are different, and the shapes of the third sub-touch electrode 200a and the fourth sub-touch electrode 200b are different.
[0058] In a possible implementation manner, the shapes of the orthographic projections of the second sub-touch electrode and the fourth sub-touch electrode on the substrate include: triangle, rectangle, and rhombus.
[0059] Generally, the touch area is rectangular. In order to fill the electrode pattern as much as possible in the touch area and make the electrode array composed of the first touch electrode and the second touch electrode conform to the rectangular shape of the touch area, the shapes of the first touch electrode and the second touch electrode can include Figure 2 the rhombus shown, and triangle. Exemplarily, the shapes of the first touch electrode and the second touch electrode located at the outermost edge position of the electrode array are isosceles triangles, and the first touch electrode and the second touch electrode located in the middle position of the electrode array are a combined pattern of two isosceles triangles, such as a rhombus. In this way, the overall shape of the composed electrode array is a rectangle that is the same as or similar to the shape of the touch area. The rectangle shown by the dotted line in Figure 2 can be used as an electrode unit, and the touch electrode array of the touch layer is regarded as a combination of multiple such electrode units. The structure of each electrode unit is as shown in Figure 2 In the orthographic projection on the substrate, it is a square pattern. The two diagonals of the square pattern intersect to divide and obtain four triangular regions; each electrode unit includes a driving electrode and a sensing electrode, and a metal bridge structure (the first connection part and the second connection part) located at the intersection of the diagonals; among them, the driving electrode is located in two opposite triangular regions of the four triangular regions, and the sensing electrode is located in the other pair of opposite triangular regions of the four triangular regions; the metal bridge structure is used to connect the driving electrodes located in the opposite two triangular regions, and to connect the sensing electrodes located in the other pair of opposite two triangular regions.
[0060] This application proposes to improve the touch layer structure by arranging the touch electrodes on the side (that is, not using the method of centering and filling). In this idea, there are mainly two cases: Case 1 is to arrange the touch electrode array as a whole on the left or right side in the touch area; Case 2 is to arrange multiple rows of touch electrodes on the left in the touch area, and arrange multiple other rows of touch electrodes on the right in the touch area. Hereinafter, these two cases will be described separately.
[0061] Case 1: The touch electrode array is arranged entirely on the left or right side within the touch area.
[0062] In a possible embodiment, the touch area is divided into two regions along the row direction: a first region and a second region;
[0063] In the first region and the second region, the first sub-touch electrode and the third sub-touch electrode are both arranged close to the first border area, and the second sub-touch electrode and the fourth sub-touch electrode are both arranged close to the second border area.
[0064] Alternatively, in the first region and the second region, the first sub-touch electrode and the third sub-touch electrode are both arranged close to the second border area, and the second sub-touch electrode and the fourth sub-touch electrode are both arranged close to the first border area.
[0065] Specifically, referring to Figure 4 , Figure 4 shows a schematic diagram of the arrangement of the touch electrodes in Case 1. As shown in Figure 4 , the touch area is divided into a first region and a second region along the row direction, which can make the areas of the first region and the second region equal. For example, the touch screen is divided into an upper half screen and a lower half screen. The first region and the second region are compensated on the same side, that is, the arrangement methods of the touch electrodes in the first region and the second region are the same. The touch electrode array is arranged on the left side (i.e., the side where the second sub-touch electrode and the fourth sub-touch electrode are close to the first border area). According to the original shape of the touch electrode array, there will be a vacant area on the right side. In this application, a compensation structure is added to the corresponding touch electrodes on the right side, so that the first sub-touch electrode and the third sub-touch electrode are arranged on the right side (close to the second border area). Since a corresponding compensation structure is added in the area where there are no touch electrodes (the edge area of the touch area close to the second border area), each corner in the touch area of the touch panel is completely filled with a pattern, solving the problem of poor touch performance in the edge area of the panel.
[0066] Case 2: Multiple rows of touch electrodes are arranged on the left within the touch area, and multiple other rows of touch electrodes are arranged on the right within the touch area.
[0067] In a possible embodiment, the touch area is divided into two regions along the row direction: a first region and a second region;
[0068] In the first region, the first sub-touch electrode and the third sub-touch electrode are arranged close to the second border area, and the second sub-touch electrode and the fourth sub-touch electrode are arranged close to the first border area;
[0069] In the second region, the second sub-touch electrode and the fourth sub-touch electrode are disposed close to the second border region, and the first sub-touch electrode and the third sub-touch electrode are disposed close to the first border region.
[0070] Alternatively, in the first area, the first sub-touch electrode and the third sub-touch electrode are arranged close to the first border area, and the second sub-touch electrode and the fourth sub-touch electrode are arranged close to the second border area; in the second area, the second sub-touch electrode and the fourth sub-touch electrode are arranged close to the first border area, and the first sub-touch electrode and the third sub-touch electrode are arranged close to the second border area.
[0071] Specifically, refer to Figure 5 , Figure 5 FIG. 2 shows a schematic diagram of the arrangement of touch electrodes in case 2, such as Figure 5 As shown, the touch area is divided into the first area and the second area along the row direction, so that the area of the first area and the second area can be equal, for example, the touch screen is divided into the upper half screen and the lower half screen. The first area and the second area are compensated on different sides, that is, the touch electrodes of the first area and the second area are arranged differently. The upper and lower half screens are staggered and filled, which is particularly suitable for the case of upper and lower folding screens. For example, the lower half screen pattern is filled on the left, and the upper half screen pattern is filled on the right.
[0072] For the first area, the touch electrode array is arranged on the left side (that is, the second sub-touch electrode and the fourth sub-touch electrode are close to the side of the first border area). According to the original touch electrode array, a vacant area will be generated on the right side. This application adds a compensation structure to the corresponding touch electrodes on the right side, so that the first sub-touch electrode and the third sub-touch electrode are arranged on the right side (close to the side of the second border area).
[0073] For the second area, the touch electrode array is arranged on the right side (that is, the second sub-touch electrode and the fourth sub-touch electrode are close to the side of the second border area). According to the original touch electrode array, a vacant area will be generated on the left side. This application adds a compensation structure to the corresponding touch electrodes on the left side, so that the first sub-touch electrode and the third sub-touch electrode are arranged on the left side (close to the side of the second border area).
[0074] In this embodiment, since a corresponding compensation structure is added in the area where touch electrodes are not set (the edge area close to the second border area in the first area of the upper half screen, and the edge area close to the first border area in the second area of the lower half screen), each corner in the touch area of the touch panel is completely filled with a pattern, thereby solving the problem of poor touch performance in the edge area of the panel.
[0075] In the electrode arrangement scheme of Case 1, since the electrode arrangement methods in the first region and the second region are the same, the central symmetry axes of each column of the first touch electrodes along the column direction overlap, and the central symmetry axes of each column of the second touch electrodes along the column direction overlap. In the electrode arrangement scheme of Case 2, since the electrode arrangement methods in the first region and the second region are different, from the perspective of the column direction, there is a dislocation phenomenon between the touch electrodes in the first region and the touch electrodes in the second region. Specific descriptions are given in the following embodiments.
[0076] In a possible implementation manner, among the multiple interconnected second touch electrodes, the central axes of the multiple second touch electrodes located in the first region are parallel to the central axes of the multiple second touch electrodes located in the second region, and the perpendicular distance therebetween is a first distance, and the first distance is greater than 0.
[0077] Specifically, as Figure 5 shown, in the first region, for each column of the second touch electrodes arranged along the column direction (i.e., the multiple interconnected second touch electrodes), the central axis of the multiple second touch electrodes located in the first region (such as Figure 5 the dashed line 1) is parallel to the central axis of the multiple second touch electrodes located in the second region (such as Figure 5 the dashed line 2), and the perpendicular distance therebetween is a first distance A, and the first distance A is greater than 0.
[0078] In a possible implementation manner, the multiple first touch electrodes in the same row include a fifth sub-touch electrode, and the fifth sub-touch electrode is located between the first sub-touch electrode and the second sub-touch electrode;
[0079] After the multiple interconnected fifth sub-touch electrodes located in the first region are translated by a first distance along the row direction, they are axisymmetric with the multiple interconnected fifth sub-touch electrodes located in the first region, and the first distance is greater than 0.
[0080] Referring to Figure 6 , Figure 6 shows another schematic diagram of the arrangement of the touch electrodes. As Figure 6 shown, the multiple first touch electrodes in the same row include a fifth sub-touch electrode 100c. The fifth sub-touch electrode 100c is located between the first sub-touch electrode 100a and the second sub-touch electrode 100b, indicating the multiple connected touch electrodes at the middle position in the first touch electrodes in the same row. After the multiple interconnected fifth sub-touch electrodes located in the first region (i.e., the fifth sub-touch electrodes 100c in the same row) are translated by a first distance along the row direction, they are axisymmetric with the multiple interconnected fifth sub-touch electrodes located in the first region, as Figure 6As shown, the dashed line 3 represents a plurality of fifth sub-touch electrodes 100c in the same row within the first region, and the dashed line 4 represents a plurality of fifth sub-touch electrodes 100c in the same row within the second region. Translating the dashed line 3 along the row direction by a first distance A forms an axisymmetric relationship with the dashed line 4. Among them, the first distance A is greater than 0.
[0081] In a possible implementation manner, the first sub-touch electrode and the third sub-touch electrode are arranged on the same layer.
[0082] Specifically, in this embodiment, the first touch electrode and the second touch electrode are arranged on different layers. However, the compensation structures added for the corresponding first touch electrode or second touch electrode can all be located in the same film layer. Therefore, after adding the compensation structures, the generated first sub-touch electrode and third sub-touch electrode can be regarded as being on the same film layer, that is, the partial electrode blocks serving as compensation structures in the first sub-touch electrode and the partial electrode blocks serving as compensation structures in the third sub-touch electrode are located in the same film layer and can be arranged on the same layer.
[0083] This application proposes to add corresponding compensation structures in the area of the vacant electrodes (i.e., within the touch area), and connect the compensation structures to the corresponding touch electrodes (the orthographic projection of the compensation structure on the substrate does not overlap with the orthographic projection of the touch electrode on the substrate) to improve the touch layer structure. In this idea, a corresponding first touch electrode compensation structure is added for the first touch electrode to generate a first sub-touch electrode 100a; a corresponding second touch electrode compensation structure is added for the second touch electrode to generate a third sub-touch electrode 200a. The following embodiments specifically illustrate the relevant content of the compensation structure.
[0084] In a possible implementation manner, a plurality of the first sub-touch electrodes arranged adjacent to the same side border area and arranged in the column direction are separated from each other, and a third sub-touch electrode is arranged between two adjacent first sub-touch electrodes in the column direction.
[0085] Specifically, as Figures 3 to 6 shown, for the first touch electrodes in the same row, they are connected through a first connecting portion, and the first touch electrodes in different rows are not connected to each other. For a plurality of first sub-touch electrodes 100a adjacent to the same side border area (the first border area or the second border area), they are arranged in the same column in the column direction and are separated from each other. That is, when adding a compensation structure for the first touch electrode to obtain a first sub-touch electrode, a compensation structure is added separately for each first touch electrode, and the compensation structure can be Figure 6 the rectangles A1, A2, and A3 shown as such, thereby generating corresponding first sub-touch electrodes, and the plurality of first sub-touch electrodes are not connected to each other. From the column direction, a third sub-touch electrode is arranged between two adjacent first sub-touch electrodes. It should be noted that although Figure 6The position and shape of the compensation structure are outlined by solid lines, but generally, the compensation structure and the connected electrode unit are regarded as a whole, that is, it is represented as Figures 3 - 5 the shape of the first sub-touch electrode shown in
[0086] In a possible implementation manner, the touch panel further includes:
[0087] a plurality of first touch leads and a plurality of second touch leads;
[0088] Each of the first touch leads is connected to the first sub-touch electrode or the second sub-touch electrode in the corresponding row of the first touch electrodes, and the first touch lead is located in the first border area or the second border area;
[0089] Each of the second touch leads is connected to one of the second touch electrodes at both ends of the corresponding column of the second touch electrodes, and the second touch lead is located in the third border area, and the third border area is located between the first border area and the second border area.
[0090] In this embodiment, the touch panel includes a plurality of first touch leads and a plurality of second touch leads, and the first touch leads and the second touch leads can be double-layer metal wires or single-layer metal wires. In the embodiments of the present application, the proposed touch panel can be a 1T1R type touch panel, that is, the first touch lead and the second touch lead are the driving channel Tx line and the sensing channel Rx line, and there is a group of Tx line and Rx line respectively, that is, the corresponding 1T1R type touch panel. Refer to Figure 7 , Figure 7 shows a schematic diagram of the connection relationship of a touch lead. As Figure 7 shown, each first touch lead is connected to the corresponding row of first touch electrodes, specifically connected to the electrode at any one end of the first touch electrodes in that row (the first sub-touch electrode or the second sub-touch electrode). As Figure 7 shown, the three first touch leads T4, T5, and T6 in the first area are respectively connected to the first sub-touch electrodes in the corresponding rows, and the three first touch leads T1, T2, and T3 in the second area are respectively connected to the second sub-touch electrodes in the corresponding rows. The first touch leads are located in the first border area or the second border area. Exemplarily, for the first touch leads, the first touch leads connecting the first touch electrodes in the first area can be located in the first border area, and the first touch leads connecting the first touch electrodes in the second area can be located in the second border area.
[0091] Each second touch lead is connected to the corresponding column of second touch electrodes, specifically connected to the electrode at any one end of the second touch electrodes in that column. As Figure 7As shown, the second touch leads R1, R2, R3, and R4 are respectively connected to the second touch electrodes of the corresponding columns, and the second touch leads are located in the third border area as shown in Figure 7 . The third border area is located around the touch area and is between the first border area and the second border area.
[0092] In a possible implementation, multiple third sub-touch electrodes arranged in the column direction are also connected through a third connection part;
[0093] Wherein, the first sub-touch electrode adjacent to the third sub-touch electrode is located between the second connection part and the third connection part.
[0094] Specifically, as shown in Figure 6 , for the second touch electrodes in the same column, they are connected through the second connection part, and the second touch electrodes in the same row are not connected to each other. For multiple third sub-touch electrodes 200a close to the same side border area (the first border area or the second border area), they are arranged in the same column in the column direction and are connected through the second connection part. That is, when adding a compensation structure to the second touch electrode to obtain the third sub-touch electrode 200a, a compensation structure is added separately for each second touch electrode, and this compensation structure can be the rectangle shown in Figure 6 . Thus, the corresponding third sub-touch electrodes 200a are generated, and multiple third sub-touch electrodes 200a can also be connected through the third connection part 202 (when the third sub-touch electrode belongs to the driving electrode, the driving signal can be made stronger). From the column direction, a first sub-touch electrode is arranged between two adjacent third sub-touch electrodes. Therefore, the first sub-touch electrode adjacent to the third sub-touch electrode is located between the second connection part 201 and the third connection part 202.
[0095] In a possible implementation, the second sub-touch electrode in the same row as the first sub-touch electrode is connected to the first touch lead.
[0096] As shown in Figure 6 , since multiple third sub-touch electrodes 200a are connected through the third connection part 202, the first sub-touch electrode between two adjacent third sub-touch electrodes 200a cannot be connected to the first touch lead (because if the first sub-touch electrode wants to be connected to the first touch lead, it needs to pass through the third connection part). Therefore, the first touch lead of the first touch electrode in this row can only be connected to the second sub-touch electrode on the opposite side.
[0097] The structures of the first touch electrode and the second touch electrode proposed above are illustrated by the following Examples 1 and 2.
[0098] Example 1
[0099] See Figure 8 , Figure 8 which shows a schematic layout diagram of the touch electrodes in Embodiment 1. As Figure 8 shown
[0100] in Embodiment 1, the first region and the second region are compensated on the same side, that is, the compensation structures are all located on the same side (such as Figure 8 the side close to the first border region shown), that is, in the first region and the second region, the first sub-touch electrodes and the third sub-touch electrodes are both arranged close to the first border region, and the second sub-touch electrodes and the fourth sub-touch electrodes are both arranged close to the second border region.
[0101] For the compensation structure of the first touch electrode, a plurality of the first sub-touch electrodes arranged close to the same side border region and arranged in the column direction are separated from each other (such as Figure 8 A1, A2, A3 shown), and a third sub-touch electrode is arranged between two adjacent first sub-touch electrodes in the column direction.
[0102] The touch panel further includes: a plurality of first touch leads and a plurality of second touch leads; in the first region, each first touch lead is connected to the first sub-touch electrode in the corresponding row of the first touch electrodes (such as Figure 8 T4, T5, T6 shown); in the second region, each first touch lead is connected to the second sub-touch electrode in the corresponding row of the first touch electrodes (such as Figure 8 T1, T2, T3 shown), and the first touch leads are located in the first border region or the second border region. Each second touch lead is connected to one of the second touch electrodes at both ends of the corresponding column of the second touch electrodes (such as Figure 8 R1, R2, R3, R4 shown), and the second touch leads are located in the third border region, and the third border region is located between the first border region and the second border region. Among them, the first sub-touch electrode adjacent to the third sub-touch electrode is located between the second connection part and the third connection part.
[0103] In this Embodiment 1, the shapes of the orthographic projections of the second sub-touch electrodes and the fourth sub-touch electrodes on the substrate are triangular. For each row of the first touch electrodes, the shape of the first touch electrode located between the first sub-touch electrode and the second sub-touch electrode is diamond-shaped; for each row of the second touch electrodes, the shape of the second touch electrode located between the third sub-touch electrode and the fourth sub-touch electrode is diamond-shaped.
[0104] Embodiment 2,
[0105] See Figure 9 ,Figure 9 The figure shows a schematic layout diagram of the touch electrodes in Embodiment 2. As Figure 9 shown, in Embodiment 2, the first region and the second region are compensated on opposite sides, that is, the compensation structures are located on different sides (such as Figure 9 a compensation structure is added on the side of the second region close to the first border region as shown, and a compensation structure is added on the side of the touch electrodes in the first region close to the second border region), that is, in the first region, the first sub-touch electrodes and the third sub-touch electrodes are arranged close to the second border region, and the second sub-touch electrodes and the fourth sub-touch electrodes are arranged close to the first border region; in the second region, the second sub-touch electrodes and the fourth sub-touch electrodes are arranged close to the second border region, and the first sub-touch electrodes and the third sub-touch electrodes are arranged close to the first border region.
[0106] Among them, there is a dislocation in the electrode layout between the first region and the second region. Specifically, among the multiple second touch electrodes connected to each other, the central axes of the multiple second touch electrodes located in the first region are parallel to the central axes of the multiple second touch electrodes located in the second region, and the perpendicular distance therebetween is a first distance, and the first distance is greater than 0. The multiple first touch electrodes in the same row include a fifth sub-touch electrode, and the fifth sub-touch electrode is located between the first sub-touch electrode and the second sub-touch electrode; after the multiple connected fifth sub-touch electrodes located in the first region are translated by the first distance along the row direction, they are axisymmetric with the multiple connected fifth sub-touch electrodes located in the first region, and the first distance is greater than 0.
[0107] For the compensation structure of the first touch electrodes, the multiple first sub-touch electrodes arranged close to the same side border region and arranged in the column direction are separated from each other (such as Figure 9 A1, A2, A3 shown), and a third sub-touch electrode is arranged between two adjacent first sub-touch electrodes in the column direction.
[0108] The touch panel further includes: a plurality of first touch leads and a plurality of second touch leads; in the first region, each first touch lead is connected to the second sub-touch electrode in the corresponding row of the first touch electrodes (such as Figure 9 T4, T5, T6 shown); in the second region, each first touch lead is connected to the first sub-touch electrode in the corresponding row of the first touch electrodes (such as Figure 9 T1, T2, T3 shown), and the first touch leads are located in the first border region or the second border region. Each second touch lead is connected to one of the second touch electrodes at both ends of the corresponding column of the second touch electrodes (such as Figure 9as shown, R1, R2, R3, R4), the second touch lead is located in the third border area, and the third border area is located between the first border area and the second border area. Among them, the first sub-touch electrode adjacent to the third sub-touch electrode is located between the second connection part and the third connection part.
[0109] In this Embodiment 2, the shapes of the positive projections of the second sub-touch electrode and the fourth sub-touch electrode on the substrate are isosceles triangles. For each row of the first touch electrodes, the shape of the first touch electrode located between the first sub-touch electrode and the second sub-touch electrode is a combined pattern of two isosceles triangles, such as a rhombus; for each row of the second touch electrodes, the shape of the second touch electrode located between the third sub-touch electrode and the fourth sub-touch electrode is a combined pattern of two isosceles triangles, such as a rhombus.
[0110] In summary, for the current filling method after the touch pattern array, it is centered filling. This method is likely to result in a situation where the pattern integrity on both the left and right sides is less than 100%, such that there are no touch electrodes in some areas (the edge areas on both sides) of the touch area, leading to poor edge touch performance. To solve this problem, the embodiments of the present application propose to improve the touch layer structure from two aspects: on the one hand, setting the touch electrodes against the edge (i.e., not using the centered filling method), and on the other hand, adding corresponding compensation structures in the areas of the vacant electrodes. For example, when the pattern is arranged closely on the right side, only by compensating the pattern on the other side (left side), a complete pattern touch state on both sides can be achieved. Specifically, in the touch electrode layer of the touch panel, compensation structures are added to the first touch electrode and the second touch electrode respectively, to obtain the first touch sub-electrode in the first touch electrode and the third touch sub-electrode in the second touch electrode (in the positive projection on the substrate, the area of the first sub-touch electrode is larger than the area of the second sub-touch electrode, and the area of the third sub-touch electrode is larger than the area of the fourth sub-touch electrode). Since corresponding compensation structures are added in the areas where there are no touch electrodes, the pattern is completely filled in every corner of the touch area of the touch panel, solving the problem of poor touch performance in the edge areas of the panel.
[0111] The second aspect of the embodiments of the present application also provides a touch device, including the touch panel described in the first aspect of the present application.
[0112] The touch device proposed by the embodiments of the present application can be any product or component with touch function, such as a display, a television, a digital camera, a mobile phone, a tablet computer, an electronic photo frame, etc.

[0115] A first barrier layer 3 is prepared on the first inorganic layer 2. Specifically, the first barrier layer 3 is spread on the first inorganic layer 2.

The first barrier layer 3 (Barrier) can be formed of inorganic insulating materials such as silicon oxide, silicon nitride, or silicon oxynitride.
[0116] A first touch layer 4 is prepared on the first barrier layer 3. Specifically, the preparation of the first touch layer 4 (TMA) includes growing the first touch layer 4 on the first barrier layer so that the electrode material of the first touch layer can be patterned, performing photolithography and patterning on the first touch layer to form the first touch electrode proposed in the first embodiment of the present application.
[0117] A first insulating layer 5 (Touchinsulator, TLD) is formed on the first touch control layer 4 .
[0118] A second touch layer 6 is prepared on the first insulating layer 5. Specifically, the preparation of the second touch layer 6 (TMB) includes performing a patterning process such as photolithography or punching on the first insulating layer, and growing the second touch layer 6 on the first insulating layer, so that the electrode material of the second touch layer can be filled in the pattern on the first insulating layer, and finally performing a photolithography and patterning process on the second touch layer to form the second touch electrode proposed in the embodiment of the first aspect of the present application.
[0119] A protective layer 7 is prepared on the second touch layer 6. Specifically, the protective layer 7 can be prepared by using a Touch of Color (TOC) process.
