If the wire is broken and not repaired, the array substrate becomes a defective product. As a result, product yields are reduced and production costs are increased accordingly. Therefore, the repair method for the array substrate and its data line disconnection needs further study.
- Various wires such as data lines, scan lines, signal lines, and the like may be included on the array substrate.
- the present disclosure will be described by taking a data line as an example, but it should be understood that the content of the present disclosure is equally applicable to other types of wires.
- Fig. 1 schematically shows the structure of an array substrate in the related art.

- the data line 20 and the first conductive light-shielding pattern 30 are electrically insulated from each other. As shown in FIG. 2B, the data line 20 and the first conductive light-shielding pattern 30 are separated by an insulating layer so that the two are not connected to each other.
- the data line 20 is disconnected and the disconnection position is between the segments of the data lines corresponding to the two overlapping regions 231 and 232 (such as at A in FIG. 2A), the first overlap region 231 may be made to correspond.
- a segment of the data line is electrically coupled to the segment of the first conductive light-shielding pattern and electrically interconnects the first conductive light-shielding pattern corresponding to the second overlap region 232 and the segment of the data line.
- the current on the wire can be transferred by means of the first conductive light-shielding pattern (see the arrow in Fig. 2A), thereby realizing the repair of the above-mentioned open circuit.
- the term “the conductive light-shielding pattern extends in the second direction” herein refers to guiding at least one continuous connecting line between the first end and the second end of the electric shading pattern in the second direction, so that The first end and the second end are electrically connected.
- specific types of substrates include, but are not limited to, a glass substrate and a polymer substrate as long as the use requirements are met.
- the substrate can be a conventional substrate known in the art.
- the material forming the wire may include a metal or a metal alloy such as a material such as copper, silver, molybdenum, aluminum, or a molybdenum-tungsten alloy.
- a metal or a metal alloy such as a material such as copper, silver, molybdenum, aluminum, or a molybdenum-tungsten alloy.

Repair, help complete the transmission of data signals, and thus improve product yield.
- the array substrate may further include a second conductive light shielding pattern 35 between the adjacent two sub-pixel units.
- 3A and 3B schematically illustrate top and cross-sectional views of an array substrate in accordance with yet another embodiment of the present disclosure.
- the second conductive light shielding pattern 35 is electrically insulated from the wires 20.
- the second conductive light-shielding pattern 35 includes two second regions 36 and 37, the orthographic projection of the two second regions on the substrate overlapping the orthographic projection of the wires on the substrate.
- An orthographic projection of the first conductive light-shielding pattern 30 on the substrate 10 and an orthographic projection of the second conductive light-shielding pattern 35 on the substrate 10 are located on the substrate 10 on the substrate 10. Both sides of the orthographic projection.
- an orthographic projection of each of the two first regions on the substrate coincides with an orthographic projection of a corresponding one of the two second regions on the substrate. More specifically, in some embodiments, each of the two first regions coincides with a corresponding one of the two second regions, that is, the first region 31 and the second region 36 coincide, first Region 32 coincides with second region 37.
- the combination of the first conductive light-shielding pattern 30 and the second conductive light-shielding pattern 35 has a closed loop shape. Thereby, the signal of the wire can be transmitted through the conductive light-shielding patterns on both sides thereof, and the reliability is higher.
- the combination of the first conductive light-shielding pattern 30 and the second conductive light-shielding pattern 35 may not be closed as long as one conductive light-shielding pattern can be used in the method of repairing the open circuit.

Thus, after the wires corresponding to the overlapping regions and the segments of the conductive light-shielding pattern are electrically connected, the signals of the wires are transmitted only through one conductive light-shielding pattern.
- the wire and the conductive light shielding pattern may be electrically connected by a method of laser melting.
- the method of repairing a wire break according to an embodiment of the present disclosure is easy to operate, has a high success rate, and is low in cost.

- the strip electrode 41 closest to the wire among the common electrodes can provide a stable voltage to the conductive light-shielding pattern, preventing the conductive light-shielding pattern from generating a floating electric field whose intensity cannot be controlled.
- the common electrode has a vertical slit structure, which facilitates the use of the conductive light-shielding pattern to repair the electrical connection between the common electrode (the remaining strip electrode) and the conductive light-shielding pattern when the wire is broken, thereby avoiding the interaction between the common electrode signal and the wire signal.
- the common electrode further includes a plurality of connections.
