Definitions
- the base substrate includes a lead region and a pixel region, the first electrode is located in the lead region, and the second electrode is located in the pixel region.
- the projection of the source/drain on the substrate substrate falls within the projection of the data line lead extension on the substrate.
- FIG. 3 is a schematic structural diagram of an array substrate according to another embodiment of the present disclosure.
- 4a, 4b, 4c, 4d, 4e and 4f are schematic structural views of the array substrate of the embodiment shown in Fig. 3 at various stages of the preparation process.
- the array substrate of the embodiments of the present disclosure is applicable to all array substrates having data line leads and source/drain electrodes which are alternately disposed and connected in a via connection.
- data lines and data line leads formed of a metal material are described as an example.
- the metal forming the data lines and data line leads can be a metal element or alloy.
- the data lines and data line leads can also be formed from other conductive materials such as conductive oxides.
- the data lines and data leads may comprise a single layer, a double layer or a multilayer structure.
- a repair member is provided between the data line lead 3W and the source/drain 7.
- the repair component includes, for example, a conductive material. The repairing member is electrically connected to the data line lead 3W and overlaps at least a portion of the source/drain 7.
- the size of the overlap portion can be specifically determined according to actual needs or cost, as long as it can satisfy the electrical connection between the data line lead extension portion 4 and the source/drain 7 by laser welding, and the data line lead 3W and the source/ It is sufficient that the drains 7 are turned on.
- a gate electrode 2 As shown in FIG. 2a, a gate electrode 2, a data line lead 3W, and a data line lead extension portion 4 are formed on the base substrate 1, so that the data line lead extension portion 4 extends from the lead region of the base substrate 1 to the pixel region.
- the first via 81 in order to ensure that the first conductive layer 9 can be connected to the data line lead 3W, the first via 81 needs to pass through the first insulating layer 5 and the second insulating layer 8 at the same time. However, when the second insulating layer 8 covers only a portion of the first insulating layer 5, the first via 81 only needs to pass through the first insulating layer 5. In the context of the present disclosure, “deep” and “lighter” are only the relative results obtained after comparing the depth of the first via 81 with the depth of the second via 82.
- the repairing member may be the conductive portion 11 disposed in the same layer as the second conductive layer 10. Therefore, the material of the repair member is the material of the second conductive layer 10. The conductive portion 11 is directly electrically connected to the source/drain electrodes 7.
- source/drain electrodes 7 are formed.
- the source/drain 7 is directly electrically connected to the conductive portion 11.
- the display device of the embodiment of the present disclosure may be any product or component having a display function such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, and the like.
- a display function such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, and the like.
- the display device of the embodiment of the present disclosure when electrostatic discharge occurs in the production process, causing an open circuit between the data line lead and the source/drain, can be repaired by the repair component, so that the data line lead and the source/drain Channels are formed between the poles, thereby increasing the production yield of the array substrate and reducing the production cost.
