The embodiment of the invention provides a touch substrate.
In one embodiment, the touch substrate comprises a touch identification area and a wiring area, the touch substrate comprises a substrate, and a touch electrode and a touch signal line which are positioned on the substrate, the touch electrode is arranged in the touch identification area, and the touch electrode is connected with the touch control chip through the touch signal line positioned in the wiring area.
In some embodiments, the touch substrate may be a display substrate, wherein the display substrate includes a display area (AA area) and a peripheral area, wherein the touch identification area covers the display area, and the routing area is disposed in the peripheral area.
In some embodiments, the touch module of the touch substrate specifically includes a first electrode layer, a touch insulating layer 130, and a second electrode layer, which are sequentially stacked.
The touch insulating layer 130 serves to insulate between the first electrode layer and the second electrode layer, and generally, one of the first electrode layer and the second electrode layer serves as a bridging key and the other serves as a touch electrode.
In this embodiment, the number of the touch signal lines is multiple, and each group of the touch signal lines is respectively used for transmitting the touch signals corresponding to different touch electrodes.
As shown in fig. 1, each group of touch signal lines includes a first signal line 110 and a second signal line 120 which are stacked.
In some embodiments, the first signal line 110 and the first electrode layer are disposed in the same material layer, and the second signal line 120 and the second electrode layer are disposed in the same material layer. As shown in fig. 2, the first signal line 110 and the second signal line 120 are isolated from each other by a touch insulating layer 130. It should be noted that, in fig. 1 and fig. 2, in order to clearly show the relative position and the stacking relationship of the first signal line 110 and the second signal line 120, only the line widths of the first signal line 110 and the second signal line 120 are exemplarily shown, in practice, the line widths of the first signal line 110 and the second signal line 120 may be adjusted as needed, and the state shown in fig. 1 and fig. 2 does not represent the actual line width relationship between the first signal line 110 and the second signal line 120.
It should be understood that each group of touch signal lines corresponds to one touch signal line, and therefore, the transmission of the touch signal line can be realized only by maintaining the connection state of at least one of the first signal line 110 and the second signal line 120 in the same group of touch signal lines.
As shown in fig. 1, the orthographic projection of the first signal line 110 on the substrate overlaps with the orthographic projection of the second signal line 120 of the same group on the substrate, and at least a part of the orthographic projection of the first signal line 110 on the substrate overlaps with the orthographic projection of the second signal line 120 of the other group on the substrate.
It can be understood that, in the technical solution of this embodiment, for the same group of touch signal lines, a portion of the first signal line 110 overlaps with the second signal line 120, a portion of the first signal line 110 does not overlap with the second signal line 120, and the first signal line 110 overlaps with the second signal line 120 of another group, where overlapping means that orthogonal projections of the two on the substrate overlap with each other.
In some embodiments, an orthographic projection of at least a portion of the second portion 112 of the first signal line 110 on the substrate overlaps an orthographic projection of the second signal line 120 of the next group on the substrate along the arrangement direction of the plurality of groups of touch signal lines.
In other embodiments, the overlapping manner of the first signal lines 110 and the second signal lines 120 can also be adjusted as needed, for example, a part of one first signal line 110 overlaps with the second signal line 120 of the group of touch signal lines located on the left side of the first signal line 110, and a part overlaps with the second signal line 120 of the group of touch signal lines located on the right side of the first signal line 110.
Referring to fig. 1 and 3, in some embodiments, at least a portion of the first signal line 110 includes a first portion 111, a second portion 112, and a third portion 113.
The first portion 111 of the first signal line 110 in this embodiment refers to a portion where the first signal line 110 overlaps with the second signal line 120 of the same group, that is, an orthographic projection of the second signal line 120 on the substrate covers an orthographic projection of the first portion 111 of the first signal line 110 of the same group on the substrate.
The second portion 112 of the first signal line 110 refers to a portion overlapping with other groups of the second signal lines 120, in other words, an orthogonal projection of the second signal lines 120 on the substrate covers an orthogonal projection of the second portion 112 of the first signal line 110 of a different group on the substrate.
The third portion 113 connects the second portion 112 and at least a part of the first portion 111, i.e. the third portion 113 forms a connection connecting the first portion 111 and the second portion 112 of each first signal line 110.
Referring to fig. 1 and 3, in some embodiments, the first portion 111 includes a first sub-portion 111A, and the first sub-portion 111A is connected to the second portion 112 via a third portion 113.
In some of the embodiments, along the extending direction of the second signal line 120, the first sub-portions 111A and the second portions 112 of the first signal line 110 are alternately arranged, and the adjacent first sub-portions 111A and the second portions 112 are connected by the third portion 113.
In this embodiment, each time the first signal line 110 extends for a certain length, that is, the second portion 112 with a certain length is disposed, it can also be understood that a maintenance point is formed, so that, for a short circuit problem occurring at different positions, the touch signal line can be maintained near the short circuit point 210, which is helpful for improving convenience of maintenance.
In some of the embodiments, the first portion 111 of the partial first signal line 110 further includes a second sub-portion 111B, the second sub-portion 111B is insulated from the second portion 112, and the second sub-portion 111B is insulated from the first sub-portion 111A. In some of these embodiments, the second sub-portion 111B is located between two adjacent first sub-portions 111A of the same first signal line 110; or the second sub-portion 111B is located between two adjacent second portions 112 of another first signal line 110.
In this embodiment, it can be understood that the second sub-portion 111B is a portion insulated from other portions of the first signal line 110, and the second sub-portion 111B and the corresponding second signal line 120 are overlapped to implement transmission of the touch signal.
The embodiment of the invention provides a maintenance method of a touch substrate.
As shown in fig. 4, in some embodiments, the method for repairing a touch substrate includes the following steps:
step 401: detecting a short-circuit point position between the two groups of touch signal lines;
step 402: and cutting off a first signal wire in one group of the two groups of touch signal wires and a second signal wire in the other group of the touch signal wires at two sides of the short circuit point position.
The cutting operation of the touch signal line can be realized by selecting laser cutting and other modes, and in this embodiment, the specific process of the cutting operation is not further limited.
It should be understood that the short circuit between the touch signal lines is generally caused by metal residue due to foreign matter residue and the like when the touch signal lines are patterned. Generally, the first signal line 110 and the second signal line 120 are fabricated by similar processes, and therefore, the first signal line 110 and the second signal line 120 are usually short-circuited at the same time near the position where the residue phenomenon occurs.
In the technical solution of this embodiment, there is a certain non-overlapping region between the first signal line 110 and the second signal line 120 of the same group of signal lines. Thus, if there is a short circuit between two sets of signal lines, the first signal line 110 of one set of touch signal lines and the second signal line 120 of the other set of touch signal lines can be cut off, after the touch signal lines are cut off, one set of touch signal lines can be connected through the second signal line 120, and the other set of touch signal lines can be connected through the first signal line 110. Thus, the maintenance method of the embodiment can eliminate the short-circuit fault of the touch substrate without affecting the transmission of the touch signal, and compared with the related art, the maintenance method of the embodiment has higher maintainability of the touch substrate.
In some embodiments, the step 402 comprises:
determining a maintenance point position corresponding to the short-circuit point position;
and cutting off the first signal line and the second signal line which are positioned at the maintenance point.
In the technical solution of this embodiment, the repair points 220 are two overlap points of the two sets of touch signal lines, where the first signal line 110 of one set of touch signal lines and the second signal line 120 of the other set of touch signal lines, and the two repair points 220 are respectively located at two sides of the short-circuit point 210 along the extending direction of the second signal line 120.
When the cutting operation of the touch signal lines is performed, the cutting depth is difficult to control, and therefore, all the touch signal lines at the same position are usually cut off.
As shown in fig. 1, in the case where an overlapping point of one first signal line 110 and a second signal line 120 of another group of touch signal lines is used as a repair point, when a cutting operation is performed at the repair point, the first signal line 110 of one group of touch signal lines and the second signal line 120 of another group of touch signal lines can be cut off by one cutting operation, so that the repair operation for the short-circuited touch signal lines can be conveniently and quickly completed.
It should be understood that the short circuit between the touch signal lines is generally caused by metal residue due to foreign matter residue and the like when the touch signal lines are patterned. Generally, the first signal line 110 and the second signal line 120 are fabricated by similar processes, and therefore, the first signal line 110 and the second signal line 120 are usually short-circuited at the same time near the position where the residue phenomenon occurs.
The embodiment of the invention also provides electronic equipment comprising the touch substrate.
Since the electronic device of this embodiment includes all the technical solutions of the above touch substrate embodiment, at least all the technical effects can be achieved, and details are not described here.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
