Before explaining the technical solutions provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically explains the problems existing in the prior art:
as described above, in order to ensure normal display of the display panel, before the display panel leaves a factory or during subsequent maintenance, the breakpoint on the signal line needs to be detected, and the detected breakpoint is repaired, so as to ensure the display effect of the display panel and avoid the problem of uneven display caused by the existence of the breakpoint. Illustratively, the display panel may include an Active-matrix organic light-emitting diode (AMOLED) display panel.
In order to improve the signal response speed and reduce the voltage drop (IR-drop), some signal lines in the display panel are arranged in a net shape, and these signal lines arranged in a net shape may be referred to as net-shaped signal lines. As shown in fig. 1, for the mesh signal line, the signal line may include a plurality of first traces L1 extending along a first direction and a plurality of second traces L2 extending along a second direction, the first traces L1 and the second traces L2 being electrically connected to each other, the first direction intersecting the second direction. Specifically, there are a plurality of intersections x between the plurality of first tracks L1 and the plurality of second tracks L2, and at each intersection x, the first track L1 and the second track L2 are electrically connected. For example, the first trace L1 and the second trace L2 are on the same film layer, that is, the first trace L1 and the second trace L2 may be patterned on the same film layer (e.g., a metal film layer). Since the first trace L1 and the second trace L2 are located at the same film layer, at each intersection x, the first trace L1 and the second trace L2 are electrically connected.
The system and the method for detecting the breakpoint of the signal line provided by the embodiment of the application can be applied to the mesh signal line, that is, can detect the breakpoint on the mesh signal line shown in fig. 1. The mesh signal line may be a mesh metal signal line, or may be a trace made of other materials, which is not limited in this embodiment.
In some embodiments, the mesh signal line may be, for example, a reference voltage Vref signal line for transmitting a reset voltage or a positive voltage VDD signal line for transmitting a positive voltage, and of course, the mesh signal line may also be a signal line for transmitting other signals, which is not limited in this embodiment.
The system and the method for detecting a breakpoint of a signal line and the electronic device provided in the embodiments of the present application are introduced below.
The technical idea of the embodiment of the application is as follows: when no breakpoint exists on the wiring to be tested, no current flows through the adjacent reference wiring, so that the adjacent reference wiring does not generate torque; when the wiring to be tested has a breakpoint, the adjacent reference wiring has current flowing through it, so that under the action of magnetic field, the adjacent reference wiring can produce torque, so that it can detect that on the wiring to be tested there is a breakpoint. Further, based on the concept that the positions of the breakpoints are different and the magnitude of the torque on the reference wiring is different, the position of the first breakpoint on the wiring to be detected is accurately determined according to the first torque by detecting the first torque of the preset position point on the reference wiring, so that the positions of the breakpoints are accurately positioned.
For easy understanding, the technical idea/solution of the embodiment of the present application is first briefly described below with reference to fig. 2, fig. 3, and fig. 4.
As shown in fig. 2, in the first wires L1 and the second wires L2, the first end of the wire a to be tested is electrically connected to the first electrode of the power module 101, and the second end of the wire a to be tested and the second end of the reference wire B are both electrically connected to the second electrode of the power module 101. The trace a to be tested may be any one of the first traces L1 and the second traces L2, and the reference trace B is a trace adjacent to the trace a to be tested and having the same extending direction as the trace a to be tested. It should be noted that the reference trace in the embodiment of the present application is not limited to only the reference trace B, and the reference trace may include one trace or multiple traces that are adjacent to the trace a to be tested and have the same extending direction as the trace a to be tested. In the embodiment of the present application, the first electrode may be a positive electrode, and the second electrode may be a negative electrode. The second end of the reference trace may be the end connected to the negative pole of the power module 101.
In a direction perpendicular to the plane of the first trace L1 and the second trace L2, a magnetic field is applied. As shown in fig. 2, when there is no breakpoint on the trace a to be tested, the current will reach the second electrode of the power module 101 through the shortest path (i.e. the trace a to be tested), and in this case, no current flows on the adjacent reference trace B, so the reference trace B will not generate torque. As shown in fig. 3, when there is a breakpoint on the trace a to be tested, the current will reach the second electrode of the power module 101 through the adjacent reference trace B, in which case the current flows through the reference trace B. According to the left-hand rule, under the action of the vertical magnetic field, the reference trace B generates a horizontal force to the right, which causes the reference trace B to generate a torque. Therefore, whether the wire A to be tested has a breakpoint can be determined by detecting whether the reference wire B has torque. For example, when the torque on the reference trace B is detected, it is determined that there is a break point on the trace a to be tested.
In addition, as shown in fig. 4, when the position of the breakpoint on the trace a to be tested is at d1, the length of the wire through which the current flows on the reference trace B is l 1; when the position of the breakpoint on the trace a to be tested is at d2, the length of the wire through which the current flows on the reference trace B is l 2. That is, when the positions of the breakpoints on the trace a to be tested are different, the lengths of the wires through which the current flows on the reference trace B are different. And because the torque generated by the reference wiring B is in positive correlation with the length of the wire through which the current flows on the reference wiring B, when the lengths of the wires through which the current flows on the reference wiring B are different, namely, the positions of breakpoints on the wiring A to be detected are different, the torque generated by the reference wiring B is different. Therefore, based on the concept that the positions of the breakpoints on the to-be-detected wiring A are different and the torque on the reference wiring B is different, the position of the first breakpoint on the to-be-detected wiring A can be determined according to the first torque by detecting the first torque of the preset position point on the reference wiring B, and the position of the breakpoint is accurately positioned.
In order to briefly explain the technical concept/technical solution of the embodiment of the present application, the system and method for detecting a breakpoint of a signal line and an electronic device provided in the embodiment of the present application are specifically explained in sequence.
First, a method for detecting a breakpoint of a signal line according to an embodiment of the present application will be described below.
Fig. 5 is a flowchart illustrating a breakpoint detection method for a signal line according to an embodiment of the present application.
As shown in fig. 5, the method may include the steps of:
and S101, applying a magnetic field perpendicular to the plane of the signal line to the signal line.
As shown in fig. 6, a magnetic field perpendicular to the plane of the signal line 10 is applied to the signal line 10. The plane of the signal line 10 is the plane of the first traces L1 and the second traces L2.
It should be noted that the direction of the magnetic field may be perpendicular to the plane of the signal line 10 and downward, and the symbol is
Figure BDA0003139038650000081
It may be that the symbol is "" which is perpendicular to the plane of the signal line 10.
S102, obtaining a first torque of a preset position point on the reference trace.
In this embodiment, the predetermined position point may be a position point located on the reference trace and having a predetermined distance from the second end (the end-most) of the reference trace, and in some specific embodiments, the predetermined position point may be, for example, the second end (the end-most) of the reference trace, the first end of the reference trace is an end of the reference trace close to the first end of the trace to be detected, and the second end of the reference trace is an end of the reference trace close to the second end of the trace to be detected. It should be noted that the specific length of the preset distance may be flexibly adjusted according to the actual situation, which is not limited in the embodiment of the present application.
As shown in fig. 6, the predetermined position point may be the second end of the reference trace B (point a), or may be a position point (point B) located at the reference trace B and spaced apart from the second end of the reference trace B by a predetermined distance.
In some embodiments, the first torque at the preset position point may be obtained by the torque detection module 102 disposed at the preset position point. For example, the torque detection module 102 may include a sensor for measuring torque, referred to as a torque measurement sensor. For example, the first torque at point a on the reference trace B can be measured by a torque sensor disposed at point a on the reference trace B.
It should be noted that the first torque of the preset position point is the torque of the preset position point, and the "first" in the "first torque" is only for convenience of description and distinction and does not have any special meaning.
S103, under the condition that the first torque is larger than 0, determining the position of the first breakpoint on the to-be-tested wire corresponding to the first torque according to the first torque and the corresponding relation between the preset torque and the position of the breakpoint on the to-be-tested wire.
When there is no torque on the reference trace, i.e. the first torque is equal to 0, it can be considered that there is no breakpoint on the trace to be tested. Namely, the position of the first breakpoint on the to-be-measured route is determined only under the condition that the first torque is larger than 0.
As mentioned above, there is a relationship between the torque generated by the reference trace and the position of the breakpoint on the trace to be tested, so that the corresponding relationship between the torque generated by the reference trace and the position of the breakpoint on the trace to be tested can be predetermined, and then the position of the first breakpoint on the trace to be tested corresponding to the first torque is determined according to the obtained first torque and the corresponding relationship.
In some specific embodiments, S103 may specifically include: inputting the first torque into a pre-trained machine learning model to obtain the position of a first breakpoint on a to-be-detected route output by the machine learning model; the machine learning model is obtained by learning the corresponding relation between the torque of the preset position point on the reference wire and the position of the breakpoint on the wire to be tested.
Specifically, before S103, a machine learning model may be first constructed based on a machine learning algorithm or a neural network algorithm; then training the machine learning model by using a preset number of sample data with known actual results to obtain a trained machine learning model; the sample data can be the torque of a preset position point on a reference wiring carrying label information, and the label information can comprise the actual position of a breakpoint on the wiring to be detected. Namely, the machine learning model is trained by utilizing the torque of the preset position point on the reference wiring of the actual position of the breakpoint on the plurality of known wires to be tested, so as to obtain the trained machine learning model.
In S103, a first torque of a preset position point on the reference trace is input to the trained machine learning model, so as to obtain a position of a first breakpoint on the to-be-detected trace corresponding to the first torque.
In the embodiment of the present application, the machine learning model may include, but is not limited to, a machine learning model constructed by at least one of the following machine learning algorithms:
linear Regression algorithms, Logistic Regression (Logistic Regression) algorithms, k-nearest neighbor (KNN) algorithms, decision tree algorithms, naive bayes algorithms, Support Vector Machine (SVM) algorithms, combinatorial algorithms (Ensemble methods), and neural network algorithms. Of course, the machine learning algorithm may also be other algorithms not listed above, and the embodiment of the present application does not limit this.
Therefore, the position of the first breakpoint on the to-be-detected route can be quickly obtained only by inputting the first torque into the trained machine learning model after the first torque is obtained by pre-training the machine learning model, and the method has the advantages of small operand and high prediction speed.
In other embodiments, the correspondence between the torque of the preset position point on the preset reference trace and the position of the break point on the trace to be tested may include: and taking the torque of a preset position point on the reference wire as an independent variable and the position of a breakpoint on the wire to be tested as a function relation of a dependent variable.
With continued reference to fig. 6, the plurality of first traces L1 and the plurality of second traces L2 cross each other to form a plurality of unit cells. Along the extending direction of the reference trace B (current column direction), the length of the wire on the reference trace B through which current flows is 3 unit cells. According to the ampere force formula: f ═ ILBsin α and the torque formula N · m ═ F × L1, where α is 90 °, F is the ampere force, I is the current, B is the magnetic field strength, L is the wire length, and L1 is the moment arm length, it can be seen that, for each unit length of wire, the wire length L and the moment arm length L1 are both the length of one unit cell, and the ampere force F, the current I, and the magnetic field strength B are all the same, so the torque generated by each unit length of wire is the same. Assuming that the torque generated by the wire of each unit cell length is Δ N, and the torque at the current position point on the reference route is the sum of the torques generated by the wires through which current flows on the reference route, the torque at the point a is 3 Δ N, and the torque at the point b is 1.5 Δ N. The distance between the preset position point and the breakpoint in the extending direction of the reference wiring B (namely the length of the different cells) can be obtained according to the torque of the preset position point (such as the point a and the point B).
Illustratively, the expression of the functional relationship is as follows:

wherein (x)1,y1) Indicating the position, x, of a breakpoint on the trace to be measured1Is the abscissa, y, of the breakpoint on the trace to be measured1Is the ordinate, x, of the break point on the running line to be measured1Known as x1Equal to the abscissa of the trace to be tested; y is0A vertical coordinate representing a preset position point on the reference walking line; n m represents the torque of a preset position point on the reference route; Δ N represents the torque produced by a wire of one cell length; Δ L represents the length of one cell.
Correspondingly, S103 may specifically include: and calculating to obtain the position of a first breakpoint on the to-be-detected wiring according to the first torque of the preset position point on the reference wiring and the functional relation.
Therefore, the position of the first breakpoint on the to-be-detected walking line is calculated in real time through the obtained first torque and the predetermined functional relation, and compared with other modes, the position of the first breakpoint on the to-be-detected walking line is obtained through real-time calculation, so that the method has the advantage of high accuracy of the determined breakpoint position.
In other embodiments, a table of correspondence between the torque of the preset position point on the reference trace and the position of the breakpoint on the trace to be detected may also be pre-established, and the position of the first breakpoint on the trace to be detected corresponding to the first torque is obtained by looking up the table by using the first torque of the preset position point on the reference trace as an index key word. Of course, the position of the first breakpoint on the to-be-measured route corresponding to the first torque may also be determined in other manners, which is not limited in this application.
As shown in fig. 7, in order to avoid the problem that the position of the first breakpoint on the to-be-detected trace cannot be detected due to the existence of breakpoints in a small number of reference traces, in some embodiments, the reference trace may include a plurality of reference sub-traces, such as a reference sub-trace B1, a reference sub-trace B2, a reference sub-trace B3, and a reference sub-trace B4, and the second end of each reference sub-trace is electrically connected to the second electrode of the power module 101. Correspondingly, S102, obtaining a first torque of a preset position point on the reference trace specifically includes the following steps:
and S1021, acquiring the torque of the preset position point on each reference sub-line. With continued reference to fig. 7, taking the predetermined location point of each reference sub-trace as the second end of the reference trace as an example, the torque at point a1 of reference sub-trace B1, the torque at point a2 of reference sub-trace B2, the torque at point a3 of reference sub-trace B3, and the torque at point a4 of reference sub-trace B4 can be measured by torque detection module 102. Where a1, a2, a3, and a4 are the second end of reference sub-trace B1, the second end of reference sub-trace B2, the second end of reference sub-trace B3, and the second end of reference sub-trace B4, respectively.
S1022, determining the torque of the preset position point on the second reference sub-trace as the first torque when the torque of the preset position point on the first reference sub-trace is 0 and the torque of the preset position point on the second reference sub-trace is not 0.
In this embodiment of the application, the first reference sub-trace may be the 1 st to i th reference sub-traces among the plurality of reference sub-traces, which are arranged in order from the closest to the farthest distance from the to-be-detected trace, where i is a positive integer, and the second reference sub-trace may be one of the plurality of reference sub-traces except for the first reference sub-trace. As shown in fig. 7, according to the order from the closest to the farthest from the to-be-tested trace, the arrangement order of the reference sub-trace B1, the reference sub-trace B2, the reference sub-trace B3, and the reference sub-trace B4 is as follows: (B1 ═ B2) > (B3 ═ B4). When there is a break in reference sub-trace B1 and reference sub-trace B2, current will reach the second electrode of power module 101 through the shortest path (reference sub-trace B3 and reference sub-trace B4). In this case, the torque at the preset location point on reference sub-trace B1 and reference sub-trace B2 is 0, and the torque at the preset location point on reference sub-trace B3 and reference sub-trace B4 is not 0. Then the first reference sub-track, i.e., reference sub-track B1 and reference sub-track B2, and the second reference sub-track, i.e., one of reference sub-track B3 and reference sub-track B4. Correspondingly, in S103, the position of the first breakpoint on the to-be-tested trace corresponding to the torque of the preset position point on the second reference sub-trace can be determined according to the torque of the preset position point on the second reference sub-trace and the corresponding relationship between the preset torque and the position of the breakpoint on the to-be-tested trace.
Therefore, the torque of the preset position point on at least one reference sub-wiring can be ensured to be obtained when the wiring to be tested and a small number of reference sub-wirings have breakpoints by arranging a plurality of reference sub-wirings and measuring the torque of the preset position point on each reference sub-wiring, and then the position of the first breakpoint on the wiring to be tested is determined by utilizing the torque of the preset position point on the reference sub-wiring.
As shown in fig. 8, in order to further ensure that the finally determined position of the first breakpoint on the trace to be tested is more accurate, in some embodiments, for the reference trace or any one of the reference sub-traces, the preset position points may include a plurality of sub-position points, such as the sub-position point a1, the sub-position point b1, and the sub-position point c 1. Correspondingly, the positions of the breakpoints on the to-be-detected wiring can be respectively determined according to the plurality of sub-position points, and then the average value is obtained to obtain the final position of the first breakpoint on the to-be-detected wiring.
Specifically, the step S102 of obtaining a first torque of a preset position point on the reference trace may specifically include:
a first sub-torque is obtained for each sub-location point on the reference trace. As shown in fig. 8, the torque of the sub-position point a1, the torque of the sub-position point b1, and the torque of the sub-position point c1 on the reference trace can be obtained by the torque detection module 102.
In S103, for each sub-position point, a position of a second breakpoint on the to-be-tested trace corresponding to the first sub-torque of the sub-position point is determined according to the first sub-torque of the sub-position point and a corresponding relationship between the torque corresponding to the sub-position point and the position of the breakpoint on the to-be-tested trace.
It will be readily appreciated that the magnitude of the torque measured with reference to different points on the trace will be different. Therefore, in order to ensure the accuracy of the final result, a plurality of sub-position points may be corresponded to establish a corresponding relationship between a plurality of torques and the position of the breakpoint on the trace to be tested, such as establishing a corresponding relationship between the torque of the sub-position point a1 on the reference trace and the position of the breakpoint on the trace to be tested, establishing a corresponding relationship between the torque of the sub-position point b1 on the reference trace and the position of the breakpoint on the trace to be tested, and establishing a corresponding relationship between the torque of the sub-position point c1 on the reference trace and the position of the breakpoint on the trace to be tested.
When determining the position of the second breakpoint on the to-be-tested trace corresponding to the first sub-torque of the sub-position point a1 on the reference trace, the position of the second breakpoint on the to-be-tested trace corresponding to the first sub-torque of the sub-position point a1 on the reference trace may be determined based on the pre-established correspondence relationship between the torque of the sub-position point a1 on the reference trace and the position of the breakpoint on the to-be-tested trace. Similarly, when determining the position of the second breakpoint on the to-be-tested trace corresponding to the first sub-torque of the sub-position point b1 on the reference trace, the position of the second breakpoint on the to-be-tested trace corresponding to the first sub-torque of the sub-position point b1 on the reference trace may be determined based on the pre-established correspondence relationship between the torque of the sub-position point b1 on the reference trace and the position of the breakpoint on the to-be-tested trace. The same process is applied to refer to the position of the second breakpoint on the to-be-tested trace corresponding to the first sub-torque of the sub-position point c1 on the trace, and details are not repeated herein.
After the positions of the second breakpoints on the to-be-detected route corresponding to the first sub-torques of the sub-position points are obtained, the average value of the positions of the second breakpoints is calculated based on the positions of the second breakpoints obtained by the sub-position points, and the position of the first breakpoint on the to-be-detected route corresponding to the first torque is obtained. For example, the position of the second break point on the to-be-measured trace corresponding to the first sub-torque of the sub-position point a1 on the reference trace is Z1, the position of the second break point on the to-be-measured trace corresponding to the first sub-torque of the sub-position point b1 on the reference trace is Z2, and the position of the second break point on the to-be-measured trace corresponding to the first sub-torque of the sub-position point c1 on the reference trace is Z3, so that the position Z of the first break point on the to-be-measured trace is (Z1+ Z2+ Z3)/3.
Therefore, the finally determined position of the first breakpoint on the to-be-detected route is the average value obtained according to the plurality of sub-position points, so that the accuracy of the position of the first breakpoint on the to-be-detected route can be ensured.
