Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to an array substrate and a display panel. Background Art

[0002] During the preparation of display devices, due to the limitations of the preparation process and equipment, some wiring may be broken or foreign objects may come into contact with the wiring, resulting in poor wiring. In the preparation process of existing display devices, a detection stage for each layer of metal is set up to detect and repair each layer of metal. Specifically, taking the data line as an example, when the data line is broken or foreign objects fall on the data line, the preparation process of existing display devices will use tungsten powder or silver to set a U-shaped line after laser cutting, and then connect the U-shaped line to the data line to achieve repair. However, this process requires the use of a long-line machine to make tungsten powder or silver cross-line U-shaped long lines, resulting in low efficiency and high cost. At the same time, since this repair method requires long lines on the film, it is impossible to long lines after the display panel is prepared, and it is also impossible to repair.

[0035] In view of the technical problem that the existing display device repair method requires the use of a long-line machine for long-line repair, resulting in low repair efficiency, the embodiments of the present application provide an array substrate and a display panel for alleviating the above technical problem.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the present application provides an array substrate, and the array substrate 1 includes:

[0037] Substrate 11;

[0038] The gate layer 14 is disposed on one side of the substrate 11; the gate layer 14 includes a gate 141 and a common wiring 143;

[0039] A source-drain electrode layer 16 is disposed on a side of the gate layer 14 away from the substrate 11 , and the source-drain electrode layer 16 includes a source electrode 161 , a drain electrode 162 and a data line 163 ;

[0040] Among them, the gate layer 14 also includes a connecting line 144, and the connecting line 144 includes a first connecting line 144a and a second connecting line 144b. The first connecting line 144a connects the common line 143 located on both sides of the corresponding area of ​​the data line 163, and the second connecting line 144b connects the common line 143 located on both sides of the corresponding area of ​​the data line 163. There is a gap between the first connecting line 144a and the second connecting line 144b, and the first connecting line 144a and the second connecting line 144b are electrically connected through the common line 143.

[0041] An embodiment of the present application provides an array substrate, which sets connecting lines so that the first connecting line and the second connecting line are respectively connected to the common lines on both sides of the data line. When the data line is broken or sticks to foreign objects, since the setting directions of the data line and the first connecting line and the second connecting line intersect, the data line and the first connecting line and the second connecting line can be connected at the overlapping part. The data lines on both sides of the break or sticking to foreign objects can be conducted through the first connecting line, the common line and the second connecting line, so that the data line can be repaired without long wiring, thereby improving the efficiency of the repair. Since there is no need to run long wiring, after the display panel is prepared, the data line can still be repaired by welding the first connecting line and the second connecting line.

[0042] It should be noted that in Figure 1 The top-gate structure is used to illustrate the type of thin film transistor. Figure 2 The type of thin film transistor is illustrated by a bottom gate structure, that is, the embodiment of the present application does not limit the type of thin film transistor, and the thin film transistor can be a top gate structure or a bottom gate structure.

[0043] In one embodiment, a plurality of the first connecting lines are arranged at intervals between adjacent sub-pixels, and a plurality of the second connecting lines are arranged at intervals between adjacent sub-pixels. By repairing the first connecting lines and the second connecting lines in units of sub-pixels, when problems such as disconnection or attachment of foreign matter to the data line occur, the first connecting lines and the second connecting lines can be used to repair the problem.

[0044] In order to solve the problem that the data line is broken or the position of foreign matter attached to the data line is not fixed, resulting in low efficiency of data line repair. Figure 3 As shown, the array substrate includes a plurality of sub-pixels 21 arranged in an array, the sub-pixels 21 include a main sub-pixel 211 and a subsidiary sub-pixel 212 located on both sides of a corresponding region of a gate 141, and the spacing between the first connecting wire 144a and the second connecting wire 144b is smaller than the smallest one of the main sub-pixel 211 and the subsidiary sub-pixel 212. By making the spacing between the first connecting wire and the second connecting wire smaller than the smallest one of the main sub-pixel and the subsidiary sub-pixel, the first connecting wire and the second connecting wire use a single region of a sub-pixel as the minimum unit, and when a data line is disconnected or foreign matter is attached, the data line can be repaired through a single region of each sub-pixel, and the minimum repair unit is small, so that most of the problems such as disconnection or foreign matter attachment of the data line can be repaired, and there is no need to perform additional long wiring at the position where the data line is disconnected or foreign matter is attached, thereby improving the repair efficiency of the data line.

[0045] It should be noted that in Figure 2In the figure, the horizontal direction is the length direction of the main sub-pixel and the auxiliary sub-pixel, and the vertical direction is the width direction of the main sub-pixel and the auxiliary sub-pixel.

[0046] Specifically, the first connecting line and the second connecting line are arranged on the main sub-pixel, and the first connecting line and the second connecting line are arranged on the sub-pixel. Then, when a break occurs on the data line or foreign matter is attached to the data line at a position corresponding to the main sub-pixel and the sub-pixel, the data line can be repaired, so that the minimum repair unit of the data line is smaller.

[0047] In one embodiment, the common wiring on one side of the auxiliary sub-pixel includes three equally divided parts, and the endpoints of the first connecting wiring and the second connecting wiring are respectively located at two connecting nodes of the three parts of the common wiring. By making the endpoints of the first connecting wiring and the second connecting wiring divide the common wiring into three equally divided parts, the spacing between the first connecting wiring and the second connecting wiring is larger, which increases the possibility of disconnection on the data line or the position where foreign matter is attached to the data line is located between the first connecting wiring and the second connecting wiring, thereby improving the yield of the display panel.

[0048] In order to solve the technical problem that the abnormal conduction of the data line requires a long line, resulting in low efficiency in repairing the data line. Figure 3 , Figure 4 As shown, when the abnormal conduction area of ​​the data line 163 is located between the first connecting line 144a and the second connecting line 144b, the first connecting line 144a is disconnected from the common line 143 away from the second connecting line 144b, and the second connecting line 144b is disconnected from the common line 143 away from the first connecting line 144a. The data line 163 is disconnected in the area between the first connecting line 144a and the second connecting line 144b, and the data line 163 located on the left side of the disconnection is connected to the first connecting line 144a, and the data line 163 located on the right side of the disconnection is connected to the second connecting line 144b. By disconnecting the first connecting line and the second connecting line from the common line, the first connecting line, the second connecting line and the common line between the first connecting line and the second connecting line form a loop, and then the data line is disconnected in the abnormal conduction area, so that the data lines on both sides of the abnormal conduction area can be connected to the first connecting line and the second connecting line respectively, and the data lines on both sides of the abnormal conduction area are connected through the loop formed by the first connecting line, the second connecting line and the common line between the first connecting line and the second connecting line, avoiding the abnormal conduction area, thereby realizing the repair of the data line, and no long line is required in this process, which improves the repair efficiency of the data line and reduces the cost.

[0049] Specifically, in Figure 4 In the figure, the reference numeral 33 indicates an abnormal area on the data line. The state of the data line in the abnormal area includes a state where the data line cannot transmit signals normally, such as a broken data line, a data line in contact with a foreign object, etc. The reference numeral 31 indicates an opening of the common line. The reference numeral 32 indicates an area where the data line is connected to the first connection line and the second connection line. In this area, the data line and the first connection line and the second connection line can be directly welded or connected by tungsten powder or silver.

[0050] In one embodiment, the data line includes an opening and routing lines located on both sides of the opening, the opening is located in a region between the first connecting routing line and the second connecting routing line, and the abnormal conduction region of the data line is located in one of the data lines on both sides of the opening. By forming an opening on the data line, the data line is disconnected in a region between the first connecting routing line and the second connecting routing line, and then the data lines on both sides are connected through the first connecting routing line and the second connecting routing line, thereby eliminating the influence of the abnormal conduction region on the data line, and completing the repair of the data line.

[0051] After the data line is interrupted, the abnormal conductive area still remains on the data line, which may cause signal abnormality. In one embodiment, Figure 4 As shown, the data line 163 includes a first opening 163b, a second opening 163d, a first routing portion 163a, a second routing portion 163e and an abnormal routing portion 163c, the first opening 163b and the second opening 163d are located on both sides of the abnormal routing portion 163c, the first opening 163b is located on both sides of the first routing portion 163a and the abnormal routing portion 163c, the first opening 163b disconnects the first routing portion 163a and the abnormal routing portion 163c, the second opening 163d is located on both sides of the second routing portion 163e and the abnormal routing portion 163c, the second opening 163d disconnects the second routing portion 163e and the abnormal routing portion 163c. By setting the first opening and the second opening, the abnormal conductive area can be disconnected. No matter there is a problem such as open circuit, short circuit or poor contact in the abnormal conductive area, it can be disconnected, and the signal on the abnormal routing portion will not be transmitted to other routings, thereby avoiding the signal of the abnormal conductive area affecting the signals of other routings, and the first routing portion can be connected to the first connecting routing, and the second routing portion can be connected to the second connecting routing, and the data signal is transmitted through the first routing portion, the first connecting routing, the common routing, the second connecting routing and the second routing portion.

[0052] Specifically, there is an overlapping area between the first routing portion and the first connecting routing, and there is an overlapping area between the second routing portion and the second connecting routing. The first routing portion and the first connecting routing can be connected through the overlapping area, and the second routing portion and the second connecting routing can be connected through the overlapping area, thereby realizing the transmission of data line signals.

[0053] The existing data line repair process needs to use tungsten powder or silver to repair the long line, which leads to low efficiency. In one embodiment, Figure 3 , Figure 4 As shown, the projection of the data line 163 on the substrate and the projection of the first connecting line 144a on the substrate have a first overlapping area 171, and the projection of the data line 163 on the substrate and the projection of the second connecting line 144b on the substrate have a second overlapping area 172. In the first overlapping area 171, the data line 163 is welded to the first connecting line 144a or connected by metal, and in the second overlapping area 172, the data line 163 is welded to the second connecting line 144b or connected by metal. In the present application, by setting the first connecting line and the second connecting line, the first connecting line and the second connecting line intersect with the data line. When repairing the data line, a via is directly formed in the area where the first connecting line and the second connecting line overlap with the data line, and then the first connecting line and the second connecting line are directly connected to the data line to repair the data line without using tungsten powder or silver for long lines, thereby improving the repair efficiency of the data line and reducing costs.

[0054] Specifically, when the array substrate is in the stage of testing each layer, tungsten powder or silver can be applied to the overlapping position of the data line and the first connecting line and the second connecting line, and then welding can be performed to improve the repair effect. Alternatively, the first connecting line, the second connecting line and the data line can be directly repaired.

[0055] In one embodiment, if Figure 1 As shown, the array substrate 1 further includes an interlayer insulating layer 15, and the interlayer insulating layer 15 is arranged between the gate layer 14 and the source-drain electrode layer 16. In the first overlapping region and the second overlapping region, the interlayer insulating layer is formed with a first via hole and a second via hole, and at least one of the first via hole and the second via hole is provided with a metal material. By providing the metal material in the first via hole and the second via hole, when the first connecting wire and the second connecting wire are connected to the data wire, the metal material improves the connection effect between the first connecting wire and the second connecting wire and the data wire, thereby improving the yield of the display panel.

[0056] It should be noted that, in the embodiment of the present application, since only a part of the data line is abnormal, in the driving circuit of the present application, the states of some common lines and data lines are as follows: Figure 2 As shown, the data line transmits signals normally, the common line does not need to be cut off, and the first connecting line and the second connecting line are not connected to the data line. In this state, since the signals of the common lines are the same, the first connecting line and the second connecting line will not affect the signals of the common lines.

[0057] It should be noted that when there is no abnormality in the data line, the design of the common line and the data line in the array substrate is as described above. In the area where the data line is abnormal, the status of the common line and the data line is as follows: Figure 4 As shown, at this time, the common line will be cut off by the opening, the data line will be cut off by the opening, and the first connection line and the second connection line will be connected to the data line. In this state, each common line is cut off, but the signal can still reach the common line, and it will not affect the common line. The common line is spaced from the first connection line and the second connection line, so that the signal of the data line will not generate crosstalk with the signal of the common line, so that the signal is transmitted normally.

[0058] It should be noted that Figure 2 Only the structural design of one sub-pixel is shown in the figure, but in practice, each sub-pixel will have a driving circuit design.

[0059] In one embodiment, if Figure 1 As shown, the array substrate 1 further includes an active layer 12 and a gate insulating layer 13 , and the gate insulating layer is arranged between the active layer and the gate layer.

[0060] In one embodiment, if Figure 3 As shown, the gate layer 14 further includes a scan line 142 .

[0061] At the same time, if Figure 2 , Figure 3 , Figure 5 As shown, an embodiment of the present application provides a display panel, the display panel includes an array substrate, and the array substrate includes:

[0062] Substrate 11;

[0063] The gate layer 14 is disposed on one side of the substrate 11; the gate layer 14 includes a gate 141 and a common wiring 143;

[0064] A source-drain electrode layer 16 is disposed on a side of the gate layer 14 away from the substrate 11 , and the source-drain electrode layer 16 includes a source electrode 161 , a drain electrode 162 and a data line 163 ;

[0065] Among them, the gate layer 14 also includes a connecting line 144, and the connecting line 144 includes a first connecting line 144a and a second connecting line 144b. The first connecting line 144a connects the common line 143 located on both sides of the corresponding area of ​​the data line 163, and the second connecting line 144b connects the common line 143 located on both sides of the corresponding area of ​​the data line 163. There is a gap between the first connecting line 144a and the second connecting line 144b, and the first connecting line 144a and the second connecting line 144b are electrically connected through the common line 143.

[0066] An embodiment of the present application provides a display panel, which includes an array substrate. The array substrate is provided with connecting lines so that the first connecting line and the second connecting line are respectively connected to the common lines on both sides of the data line. Then, when the data line is broken or sticks to foreign objects, since the setting directions of the data line and the first connecting line and the second connecting line intersect, the data line and the first connecting line and the second connecting line can be connected at the overlapping part. The data lines on both sides of the break or sticking to foreign objects can be conducted through the first connecting line, the common line and the second connecting line, so that the data line can be repaired without long wiring, thereby improving the efficiency of the repair. Moreover, since there is no need to run long wiring, after the display panel is prepared, the data line can still be repaired by welding the data line to the first connecting line and the second connecting line.

[0067] In one embodiment, if Figure 5 As shown, the display panel is a liquid crystal display panel, which further includes a planarization layer 411 , a pixel electrode layer 412 , a liquid crystal layer 43 and a color filter substrate 44 .

[0068] In one embodiment, the display panel is an organic light emitting diode display panel.

[0069] In one embodiment, when the abnormal conduction area of ​​the data line is located between the first connection line and the second connection line, the first connection line is disconnected from the common line away from the direction of the second connection line, the second connection line is disconnected from the common line away from the direction of the first connection line, the data line is disconnected in the area between the first connection line and the second connection line, and the data line located on the left side of the disconnection is connected to the first connection line, and the data line located on the right side of the disconnection is connected to the second connection line, the projection of the data line on the substrate and the projection of the first connection line have a first overlapping area, the projection of the data line on the substrate and the projection of the second connection line have a second overlapping area, in the first overlapping area, the data line is welded to the first connection line, and in the second overlapping area, the data line is welded to the second connection line. In the detection stage of the display panel, the prior art cannot be repaired because tungsten powder or silver long wire cannot be used, while the present application can directly interrupt the data line and the common line, and perform welding repair through the overlapping area between the data line and the first connection line and the second connection line, thereby overcoming the technical problem that the abnormality of the data line cannot be repaired in the detection stage of the display panel.

[0070] According to the above embodiments, it can be seen that:

[0071] An embodiment of the present application provides an array substrate and a display panel; the array substrate includes a substrate, a gate layer and a source-drain layer, the gate layer is arranged on one side of the substrate, the gate layer includes a gate and a common wiring, the source-drain layer is arranged on a side of the gate layer away from the substrate, the source-drain layer includes a source, a drain and a data line, wherein the gate layer also includes a connecting wiring, the connecting wiring includes a first connecting wiring and a second connecting wiring, the first connecting wiring connects the common wiring located on both sides of the corresponding area of ​​the data line, the second connecting wiring connects the common wiring located on both sides of the corresponding area of ​​the data line, there is a spacing between the first connecting wiring and the second connecting wiring, and the first connecting wiring and the second connecting wiring are electrically connected through the common wiring. The present application sets connecting lines so that the first connecting line and the second connecting line are respectively connected to the common lines on both sides of the data line. Then, when the data line is broken or stuck to foreign objects, since the setting directions of the data line and the first connecting line and the second connecting line intersect, the data line and the first connecting line and the second connecting line can be connected at the overlapping part. The data lines on both sides of the break or sticking to foreign objects can be conducted through the first connecting line, the common line and the second connecting line, thereby repairing the data line without long wiring, thereby improving the efficiency of repair. Moreover, since long wiring is not needed, after the display panel is prepared, the data line can still be repaired by welding the first connecting line and the second connecting line.
