Detailed Embodiments

[0039] The following will elaborate on the solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0040] In the following description, specific details such as specific system structures, interfaces, and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the present invention.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] The terms "first", "second", and "third" in the present invention are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined. All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0043] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0044] Currently, for data lines that are broken in the overlapping area with the gate line, the laser chemical vapor deposition method (Laser Chemical Vapor Deposition, Laser CVD) is mainly used for repair. The array substrate includes a substrate, a gate line located on the substrate, a data line intersecting with the gate line, and a common electrode located above the data line and insulated from the data line. When the data line is broken in the overlapping area with the gate line, repair can only be carried out before no other layer is provided on the layer where the data line is located. First, the data signals on both sides of the broken position of the data line are cut off to avoid signal interference between the gate line and the common electrode, and then the Laser CVD method is used to deposit a metal wire to connect the broken data line.

[0045] However, when other layers are provided on the layer where the data line is located, the data line cannot be repaired after being covered by the other layers.

[0046] Based on the current existing problems, the inventors propose a display panel and its array substrate, so that the broken data line can be repaired in the processes before the light-shielding film, thereby reducing the defect rate of the display panel.

[0047] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the display panel provided by the present invention.

[0048] In this embodiment, the display panel 100 is a liquid crystal panel. The display panel 100 includes a first substrate, a second substrate, and a liquid crystal layer 3. The first substrate and the second substrate are disposed opposite to each other, and the first substrate and the second substrate sandwich the liquid crystal layer 3 located in the spaced-apart space between the first substrate and the second substrate.

[0049] The liquid crystal layer 3 includes liquid crystal 31, and the liquid crystal 31 plays a role similar to a light valve in the display, and can control the brightness and darkness of the transmitted light, thereby achieving the effect of information display.

[0050] One of the first substrate and the second substrate is an array substrate 1, and the other is a color filter substrate 2. In this embodiment, the first substrate is the array substrate 1, and the second substrate is the color filter substrate 2.

[0051] Please refer to Figures 2 to 5 , Figure 2 which is a schematic structural diagram of the array substrate in an embodiment provided by the present invention; Figure 3 is Figure 2 a cross-sectional schematic diagram taken along line A-A of the array substrate provided by Figure 4 which is a schematic structural diagram of the array substrate in another embodiment provided by the present invention; Figure 5 which is a schematic structural diagram of the array substrate in yet another embodiment provided by the present invention.

[0052] The array substrate 1 provided in this embodiment includes a substrate 11, a gate line 12, a data line 13, a common electrode 14, and a repair line 15. Among them, the gate line 12 and the data line 13 are arranged to intersect each other and are not on the same layer, and the gate line 12 and the data line 13 are provided on one side surface of the substrate 11. The common electrode 14 is provided on one side surface of the substrate 11, and the common electrode 14 is arranged in a staggered manner with the gate line 12. The repair line 15 is insulated from the common electrode 14, and is on the same layer as the data line 13 and is arranged at intervals. The color array substrate 1 may further include other functional layers, which are the same as or similar to those in the prior art, and are not limited herein.

[0053] In one embodiment, the substrate 11 may be a transparent material with excellent mechanical properties, heat resistance, and chemical corrosion resistance. For example, alkali-free borosilicate glass.

[0054] The gate lines 12 and the data lines 13 are disposed on the same side of the substrate 11, and are insulated from each other and disposed in different layers. Specifically, the layer where the gate lines 12 are located can be disposed on the surface of the layer where the data lines 13 are located away from the substrate 11; the layer where the gate lines 12 are located can also be disposed between the layer where the data lines 13 are located and the substrate 11. The orthographic projections of the gate lines 12 and the data lines 13 on the substrate 11 intersect each other. The gate lines 12 and the data lines 13 are disposed crosswise to form a plurality of pixel regions 17. In this embodiment, the setting direction of the gate lines 12 is perpendicular to the setting direction of the data lines 13.

[0055] In one embodiment, please refer to Figure 2 and Figure 3 , the common electrode 14 and the gate lines 12 can be disposed in the same layer and at intervals, or the common electrode 14 and the gate lines 12 can be disposed in different layers. For example, the common electrode 14 can be disposed between the layer where the gate lines 12 are located and the substrate 11; the common electrode 14 can also be disposed on the surface of the layer where the gate lines 12 are located away from the substrate 11. Among them, the common electrode 14 and the gate lines 12 are insulated from each other. In this embodiment, the common electrode 14 and the gate lines 12 are disposed in the same layer and made of the same material and at intervals. In this way, when manufacturing the array substrate 1, no additional manufacturing process needs to be added, and only the transfer pattern needs to be changed, and the patterns of the common electrode 14 and the gate lines 12 can be formed through one lithography process, which can save the manufacturing cost and increase the added value of the product. Specifically, an insulating layer 18 is disposed between the layer where the common electrode 14 and the gate lines 12 are located and the layer where the data lines 13 and the repair lines 15 are located. The insulating layer 18 is disposed in the gap between the common electrode 14 and the gate lines 12 and between the gate lines 12, the common electrode 14 and the data lines 13 and the repair lines 15 respectively, so as to insulate the gate lines 12 from the data lines 13 and the repair lines 15, and insulate the common electrode 14 from the data lines 13 and the repair lines 15.

[0056] In one embodiment, as Figure 2As shown, the common electrode 14 includes a first electrode 141 and an electrode connection line 142. Among them, the first electrode 141 and the electrode connection line 142 are connected to each other and integrally formed. The first electrode 141 is located within the pixel region 17 defined by the gate line 12 and the data line 13. The orthographic projection of the first electrode 141 on the substrate 11 does not overlap with the orthographic projections of the gate line 12 and the data line 13 on the substrate 11. The electrode connection line 142 is used to connect the first electrodes 141 provided in two adjacent pixel regions 17. Specifically, the electrode connection line 142 is used to connect the first electrodes 141 provided in the pixel regions 17 on both sides of the data line 13. Among them, the orthographic projection of the electrode connection line 142 on the substrate 11 intersects with the orthographic projection of the data line 13 on the substrate 11. That is to say, the orthographic projection of the electrode connection line 142 on the substrate 11 and the orthographic projection of the data line 13 on the substrate 11 have an overlapping area. When the data line 13 breaks in the overlapping area with the gate line 12, the electrode connection line 142 closest to both ends of the break position can be welded to the data line 13 in the overlapping area to form a welding point 16 in the overlapping area.

[0057] In an embodiment, the first electrode 141 includes an opening area 1411 and a non-opening area 1412. Specifically, the non-opening area 1412 is at least provided on one side of the opening area 1411. In this embodiment, the non-opening area 1412 surrounds the opening area 1411 to form a shape. The opening area 1411 serves as the installation area for the pixel electrode. In order not to affect the installation of the pixel electrode, the orthographic projection of the repair line 13 on the substrate 11 partially overlaps with the orthographic projection of the non-opening area 1412 on the substrate 11.

[0058] In this embodiment, the orthographic projection of the electrode connection line 142 on the substrate 11 is perpendicular to the orthographic projection of the data line 13 on the substrate 11. In an embodiment, the width of the electrode connection line 142 is smaller than the width of the gate line 12.

[0059] In this embodiment, each overlapping area between the orthographic projection of the data line 13 on the substrate 11 and the orthographic projection of the gate line 12 on the substrate 11 corresponds to a repair line 15 respectively. The repair line 15 is provided on one side of the data line 13 and close to the data line 13. The repair line 15 is on the same layer as the data line 13 and is spaced apart. And the data line 13 and the data repair line 15 are provided on the side of the common electrode 14 and the gate line 12 away from the substrate 11. The repair line 15 intersects with the gate line 12 and is insulated from the common electrode 14 and the gate line 12. Among them, the repair line 15 and the data line 13 can be non-parallel, and the repair line 15 and the data line 13 can also be parallel to each other. In this embodiment, the repair line 15 and the data line 13 are parallel to each other. The material of the repair line 15 is a conductive material. In an embodiment, the material of the repair line 15 is a metal material. Specifically, the material of the repair line 15 is at least one of molybdenum, titanium, silver, aluminum, copper, and nickel.

[0060] Specifically, the orthographic projection of the repair line 15 on the substrate 11 at least partially overlaps with the orthographic projections of two adjacent common electrodes 14 on the substrate 11.

[0061] In one embodiment, the orthographic projection of the repair line 15 on the substrate 11 partially overlaps with the orthographic projection of the electrode connection line 142 or the first electrode 141 on the substrate 11. Specifically, the repair line 15 straddles the gate line 12, and the orthographic projections of both ends of the repair line 15 on the substrate 11 respectively have overlapping regions with the orthographic projections of the first electrode 141 or the electrode connection line 142 in the pixel regions 17 on both sides of the gate line 12 on the substrate 11. When the data line 13 breaks in the overlapping region with the gate line 12, both ends of the repair line 15 can be welded to the overlapping regions of the first electrode 141 or the electrode connection line 142 respectively to form welding points 16 in the overlapping regions.

[0062] In another embodiment, the common electrode 14 further includes a second electrode 143. The second electrode 143 is disposed within the pixel region 17, and the second electrode 143 is spaced apart from the first electrode 141 and the electrode connection line 142. The orthographic projection of the repair line 15 on the substrate 11 and the orthographic projection of the data line 13 on the substrate 11 respectively partially overlap with the orthographic projection of the second electrode 143 on the substrate 11. The second electrode 143 is insulated from the repair line 15 and the data line 13.

[0063] In a specific embodiment, as Figure 4 shown, the second electrode 143 includes an electrode body 1431 and an electrode extension line 1432 connected to the electrode body 1431. The electrode extension line 1432 is disposed on the side of the electrode body 1431 close to the data line 13. The width of the electrode extension line 1432 is smaller than the width of the gate line 12. The width of the electrode extension line 1432 can be the same as or different from the width of the electrode connection line 142. It is specifically set according to the actual situation.

[0064] The orthographic projection of the electrode extension line 1432 on the substrate 11 overlaps partially with the orthographic projection of the data line 13 on the substrate 11, and the orthographic projection of the repair line 15 on the substrate 11 overlaps partially with the orthographic projection of the electrode body 1431 on the substrate 11. Specifically, the orthographic projection of the electrode extension line 1432 on the substrate 11 and the orthographic projection of the data line 13 on the substrate 11 have an overlapping area. The orthographic projection of the repair line 15 on the substrate 11 and the orthographic projection of the electrode body 1431 in the pixel region 17 on both sides of the gate line 12 on the substrate 11 both have overlapping areas. When the data line 13 breaks in the overlapping area with the gate line 12, the electrode extension line 1432 closest to both ends of the break position can be welded to the data line 13 in the overlapping area, and both ends of the repair line 15 are respectively welded to the overlapping area of the electrode body 1431 to form a welding point 16 in the overlapping area.

[0065] In a specific embodiment, as Figure 5 shown, the second electrode 143 only includes the electrode extension line 1432. The orthographic projection of the electrode extension line 1432 on the substrate 11 and the orthographic projection of the data line 13 on the substrate 11 and the orthographic projection of the repair line 15 on the substrate 11 all have overlapping areas. When the data line 13 breaks in the overlapping area with the gate line 12, the electrode extension line 1432 closest to both ends of the break position can be welded to the data line 13 in the overlapping area, and both ends of the repair line 15 are respectively welded to the overlapping area of the electrode extension line 1432 to form a welding point 16 in the overlapping area.

[0066] The array substrate provided in this embodiment includes a substrate, a gate line, a data line, a common electrode, and a repair line. The gate line and the data line intersect and are disposed on the substrate; the common electrode is disposed on one side surface of the substrate and is misaligned with the gate line; the common electrode includes a first electrode located in each pixel region defined by the gate line and the data line and an electrode connection line connecting the first electrodes corresponding to adjacent two pixel regions. The repair line intersects with the gate line and is insulated from the common electrode and the gate line. The repair line and the data line are on the same layer and are spaced apart; wherein, the electrode connection line intersects with the data line, and the orthographic projection of the repair line on the substrate at least overlaps partially with the orthographic projections of adjacent two common electrodes on the substrate. In this application, by providing the repair line, when the data line breaks, the overlapping areas corresponding between the repair line and the common electrodes on both sides of the break position can be welded, and the overlapping areas corresponding between the data lines on both sides of the break position and the nearest common electrodes can be welded respectively, thereby realizing the repair of the data line when it is blocked and improving the success rate of repairing the array substrate.

[0067] Please refer to Figure 6 , Figure 6 which is a schematic flow chart of the repair method of the array substrate provided by the present invention.

[0068] This embodiment provides a repair method for an array substrate, which is applicable to repairing the data lines in the above-mentioned array substrate. The repair method for the array substrate includes the following steps.

[0069] S1: Determine the break position where the data line on the array substrate is open.

[0070] Specifically, the break position can be in the overlapping area of the data line and the gate line, or on the data line between two adjacent electrode connection lines. In another embodiment, the break position can also be on the data line between two adjacent electrode extension lines.

[0071] S2: Connect the data lines on both sides of the break position through a common electrode and a repair line by means of laser welding.

[0072] Please refer to Figure 7 , Figure 7 which Figure 6 is a schematic flow chart of a specific embodiment of step S2 in the repair method of the array substrate provided.

[0073] In one embodiment, when the common electrode only includes a first electrode and an electrode connection line, the first electrode is located in each pixel area defined by the gate line and the data line. The orthographic projection of the repair line on the substrate has an overlapping area with the orthographic projections of two adjacent first electrodes or electrode connection lines on the substrate, and the orthographic projection of the electrode connection line on the substrate has an overlapping area with the orthographic projection of the data line on the substrate. The repair line is arranged on one side of the data line and close to the data line, and the repair line is parallel to the data line. Among them, the first electrode includes an opening area and a non-opening area, and the orthographic projection of the repair line on the substrate partially overlaps with the orthographic projection of the non-opening area on the substrate.

[0074] S21: In response to the orthographic projection of the repair line on the substrate partially overlapping with the orthographic projection of the electrode connection line or the first electrode on the substrate, fuse the electrode connection line between the first electrode on the side of the data line with the break position and other first electrodes.

[0075] Specifically, after detecting the break position where the data line on the array substrate is open, fuse the electrode connection line between the first electrode on the side of the data line with the break position and other first electrodes; the fusing position is on the side of the data line away from the repair line. The fusing position is on the side of the data line away from the repair line.

[0076] In a specific embodiment, the electrode connection line between the first electrode on the side of the data line with the break position and other first electrodes is respectively fused by means of laser on the surface of the substrate away from the data line. It can also be fused by other means.

[0077] S22: Weld the overlapping regions where the data lines on both sides of the fracture position are respectively corresponding to the nearest electrode connection lines and the repair lines to the overlapping regions where the first electrodes or electrode connection lines arranged on both sides of the fracture position are respectively corresponding by means of laser welding.

[0078] Specifically, determine two overlapping regions formed by the electrode connection lines closest to the fracture position on both sides of the fracture position and the data lines, and two overlapping regions formed by the repair line corresponding to the fracture position and the electrode connection lines or the first electrodes.

[0079] In a specific embodiment, the overlapping regions are respectively welded by means of laser on the surface of the substrate far from the data lines, so that the data lines on both sides of the fracture position are respectively conducted with different electrode connection lines, and the two electrode connection lines conducted with the data lines are conducted with the same repair line to realize the repair of the data lines.

[0080] In another embodiment, on the basis of the above embodiment, the common electrode further includes a second electrode, the second electrode is arranged in the pixel region, and the second electrode is arranged at an interval from the first electrode and the electrode connection lines; the second electrode includes an electrode body and an electrode extension line connected to the electrode body, and the electrode extension line is arranged on the side of the electrode body close to the data lines.

[0081] In response to the positive projection of the electrode extension line on the substrate overlapping with the positive projection of the data line on the substrate in part, and the positive projection of the repair line on the substrate overlapping with the positive projection of the electrode body on the substrate in part, then the overlapping regions where the data lines on both sides of the fracture position are respectively corresponding to the nearest electrode extension lines and the repair lines are respectively welded to the overlapping regions where the electrode bodies connected to the nearest two electrode extension lines are corresponding by means of laser welding to form welding points in the overlapping regions. Welding can also be carried out by other means.

[0082] Specifically, determine two overlapping regions formed by the electrode extension lines closest to the fracture position on both sides of the fracture position and the data lines, and two overlapping regions formed by the repair line corresponding to the fracture position and the electrode body or the electrode extension lines.
