Embodiment 1

[0029] combine figure 2 and image 3 As shown, the substrate in this embodiment includes at least two insulated signal lines, and at least two of the signal lines are intersected, and a signal line overlapping region 100 is formed at the intersection. It should be noted that, usually, an insulating layer is provided between signal lines of different layers to realize insulation. The intersection here refers to the intersection of the orthographic projection of the signal lines on the plane where the substrate is located, and the overlapping area of ​​the signal lines corresponds to the intersection area of ​​the orthographic projection of the signal lines on the plane where the substrate is located.

[0030] The substrate also includes a first area, the signal line includes a first signal line 20 located in the first area, the substrate also includes an electrode line 10, and a jumper 1 is provided to electrically connect the electrode line 10 and the first signal line 20. ...

Embodiment 2

[0058] For ease of description and understanding, in this embodiment, the technical solution of the present invention is also described in detail by taking the thin film transistor array substrate as an example.

[0059] In the first embodiment, jumpers are set to include the first substructure located in the non-display area (that is, the first area), and a certain distance is separated between two adjacent first substructures, and the signal line overlapping area is located in the adjacent Between the two first substructures, a part of the isolation area is located in the area between the signal line overlapping area and the corresponding first substructure, that is, neither the signal line overlapping area nor the isolation area is laid Jumper, so that when the electrostatic breakdown occurs in the overlapping area of ​​the signal line, laser cutting repair can be performed in the partition area, which overcomes the problem that the jumper is easy to weld with the signal lin...

Embodiment 3

[0066] In the above two embodiments, jumpers are not laid in the signal line overlapping area, that is, neither the signal line overlapping area nor the partition area around the signal line overlapping area is laid with signal lines, so that when the signal lines overlap When electrostatic breakdown occurs in the overlapping area, laser cutting repair can be performed in the partition area, so as to overcome the problem that the jumper wire is easily fused with the signal line and cannot be repaired.

[0067] The difference from the above two embodiments is that the combination Figure 8-Figure 10 As shown, in this embodiment, jumpers are laid on the signal line overlapping area 100 of the substrate, and jumpers are not laid on the isolation area 200 around the signal line overlapping area 100 .

[0068] Then, the jumper 1 in this embodiment includes a third substructure 15 and a fourth substructure 16 , the third substructure 15 is laid on the periphery of the isolation area...

Abstract

The invention relates to the technical field of electronic devices, and discloses a substrate, a manufacture method thereof, and an electronic device. The substrate comprises a signal wire overlapping area, wherein the periphery of the signal wire overlapping area is provided with a partitioning area, a wire jumper is laid in at least parts of area, except the partitioning area, and therefore, laser cutting repair can be carried out in the partitioning area when the signal wire overlapping area is subjected to electrostatic breakdown. Because no wire jumpers are laid in the partitioning area, the problem that the wire jumper can not be repaired since the wire jumper is likely to be subjected to fusion welding with the signal wire can be solved, the repair rate of a product is improved, and production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a substrate, a manufacturing method thereof, and an electronic device. Background technique [0002] In the production process of the thin film transistor array substrate, static electricity is inevitably generated, and most of the electrostatic breakdown occurs in the overlapping area of ​​peripheral signal lines and jumpers. Among them, the jumper 1' is usually made of a transparent conductive layer, laid on the entire array substrate, and used to electrically connect the signal line and the electrode line, for example: the common electrode line 10 and the common signal line 20, so that the signal line Signal transmission to electrode wires, see figure 1 shown. If the electrostatic breakdown occurs in the test line, short circuit ring, maintenance line, etc., it can be repaired by cutting off the short circuit position through laser cutting. However, if the electr...
