[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] Figure 1 FIG. 1 is a schematic diagram of the structure of an array substrate provided in an embodiment of the present application. Figure 1 As shown, the array substrate includes a pad end and a pad distal end that are arranged opposite to each other in a first direction x. The array substrate includes: a substrate 100; a plurality of data lines located on the substrate 100, the data lines extending along the first direction x, the plurality of data lines arranged sequentially along a second direction y, the second direction y intersecting the first direction x; and at least one repair line W located on a side of the data line close to the pad distal end, the orthographic projection of each repair line W on the substrate 100 intersecting with the orthographic projection of at least part of the data lines on the substrate 100.

[0030] Specifically, see Figure 1The pad end of the array substrate is connected to the driver integrated circuit (IC) 200 to introduce the signal of the external circuit into the array substrate. A plurality of data lines are arranged on the substrate 100 of the array substrate for transmitting data signals. For example, the plurality of data lines include D m-4 , D m-3 , D m-2 , D m-1 , D m , D m+1 , D m+2 , D m+3 and D m+4 , are arranged in sequence along the second direction y, and extend along the first direction x, and are connected to a plurality of pixel units arranged in the display panel. Each data line transmits a data signal to each pixel unit connected thereto to control the brightness of the pixel unit.

[0031] Since the data signal is a unilateral driving signal, when the data line has a circuit break, the data signal on the path from the circuit break position to the far end of the pad cannot be transmitted normally, resulting in the brightness control of some pixel units connected to it being affected, thereby causing abnormal display. When the data line has a short circuit, the brightness control of each pixel unit connected to the data line is affected, resulting in abnormal display. At present, for the short circuit abnormality, the fuse method is generally used for repair, that is, the short circuit position is melted by heat energy to eliminate the short circuit fault. However, this repair method is complicated to operate, not easy to succeed, and cannot repair the circuit break. Therefore, the present application sets at least one repair line W on the side of the data line close to the far end of the pad, so that the positive projection of each repair line W on the substrate 100 intersects with the positive projection of at least part of the data line on the substrate 100, and the short circuit abnormality and the circuit break abnormality of the data line can be repaired. For example, at least one repair line W includes a first repair line WW1 and a second repair line WW2, and the positive projection of the first repair line WW1 on the substrate 100 and the positive projection of the data line D m-4 and D m-3 The orthographic projection on the substrate 100 intersects, and the orthographic projection of the second repair line WW2 on the substrate 100 intersects with the data line D m-4 , D m-3 , D m-2 , D m-1 and D m The positive projections on the substrate 100 intersect. It should be noted that, Figure 1 What is shown is only an example provided in this embodiment. The array substrate may include one or more repair lines W. According to actual needs, the orthographic projection of each repair line W on the substrate 100 may intersect with the orthographic projection of any one or more data lines on the substrate 100. This application does not impose any restrictions on this.

[0032] Exemplarily, the principle of the array substrate provided in this embodiment to repair the abnormal data line can be: when the data line has a circuit break abnormality, the abnormal data line is welded with the repair line W in the area where the orthographic projection of the abnormal data line on the substrate 100 and the orthographic projection of the repair line W on the substrate 100 intersect, and the repair line W is welded with the normal data line to connect the abnormal data line with the normal data line. After the abnormal data line is welded with the normal data line, the data signal transmitted by the normal data line is connected to the path from the far end of the pad to the circuit break position, thereby realizing the repair of the abnormal data line and avoiding the obvious light and dark line defect phenomenon. When the data line has a short circuit abnormality, the data lines at both ends of the short circuit position are cut off, causing the data line to be circuit broken, and the abnormal data line can be repaired by the above-mentioned repair method.

[0033] The technical solution of this embodiment is to set at least one repair line W on the side of the data line close to the far end of the pad, so that the positive projection of each repair line W on the substrate 100 intersects with the positive projection of at least part of the data line on the substrate 100, so that when the data line is short-circuited or disconnected, the normal data line is connected to the abnormal data line by using the repair line W. In this way, the area on the abnormal data line that cannot transmit signals normally can access the normal data signal, avoiding the obvious bright and dark line defect phenomenon, realizing the repair of the short-circuit abnormality and disconnection abnormality of the data line, and further improving the yield of the display panel.

[0034] Figure 2 FIG. 1 is a schematic diagram of the structure of an array substrate provided by another embodiment of the present application. Figure 2 As shown, the at least one repair line W includes a repair line W3 , and the orthographic projection of the repair line W3 on the substrate 100 intersects with the orthographic projections of all the data lines on the substrate 100 .

[0035] Specifically, a repair line W3 is set so that its orthographic projection on the substrate 100 intersects with the orthographic projections of all data lines on the substrate 100. When multiple data lines are abnormal, the multiple data lines can be repaired one by one through the repair line W3. During the repair process, the repair line W3 needs to be cut off at a suitable position to avoid signal crosstalk between multiple abnormal data lines.

[0036] For example, Figure 3 FIG. 2 is a schematic diagram of the structure of an array substrate provided by another embodiment of the present application. Figure 3 As shown, data line D m-1 and D m If an abnormality occurs in both data lines D m-1 With D m-4 , D m With D m+3Connect them together and on the data line D m-1 Connection point with repair line W3 and data line D m The repair line W3 is cut off between the connection points of the data line D m-1 and D m The repair also avoids the data line D m-1 and D m signal crosstalk between them.

[0037] In this embodiment, by setting a repair line W3 so that its orthographic projection on the substrate 100 intersects with the orthographic projections of all data lines on the substrate 100, all data lines can be repaired, which is further beneficial to improving the yield of the display panel.

[0038] In one embodiment, the array substrate includes a pixel circuit area and an edge area surrounding the pixel circuit area, and the repair line W3 is located in the edge area.

[0039] Specifically, the pixel circuit area is the area on the array substrate where the pixel circuit responsible for driving the pixel unit is located. The pixel circuit usually includes electronic components such as transistors, capacitors and light-emitting units, which are used to control the brightness and color of the pixel unit. The edge area surrounds the pixel circuit area and includes an interface for connecting to an external circuit. The repair line W3 is located in the edge area, which can reduce interference with the pixel layout. When an abnormality occurs in the data line, the repair line W3 in the edge area can be used for rapid repair without replacing the entire substrate, which can save time and cost, improve production efficiency, and further improve the yield of the display panel.

[0040] Figure 4 FIG. 1 is a schematic diagram of the structure of a display panel provided in an embodiment of the present application. Figure 4 As shown, the display panel includes the array substrate mentioned in any of the above embodiments and multiple sub-pixel columns, each sub-pixel column includes multiple sub-pixels arranged sequentially along a first direction x, the sub-pixels are located on the array substrate, and the sub-pixels in the same sub-pixel column are connected to the same data line.

[0041] Specifically, the data line is responsible for transmitting display data to each sub-pixel, so that the sub-pixel can display the corresponding color or brightness according to the received data signal. Figure 4 In the display panel, each sub-pixel includes a switch transistor, which is used to control the brightness or state of the sub-pixel. Each data line in the array substrate is connected to the source of the switch transistor of the sub-pixel connected thereto. Each data line provides a pixel voltage to the source of each switch transistor connected thereto to control the brightness or state of the sub-pixel.

[0042] This embodiment provides a display panel, in which the sub-pixels of each sub-pixel column are connected to the same data line, so that display data can be effectively controlled and transmitted, thereby realizing image display. This optimized pixel arrangement structure is conducive to improving the performance and image quality of the display panel.

[0043] Figure 5 FIG. 1 is a schematic diagram of the structure of a display panel provided by another embodiment of the present application. Figure 5 As shown, the plurality of data lines include a first data line D m-1 and the second data line D m-4 ; The first data line D m-1 With a first breakpoint b1, a first data line D m-1 The method comprises a first sub-data line located between a first breakpoint b1 and a pad end, and a second sub-data line located between the first breakpoint b1 and a far end of the pad; the plurality of sub-pixel columns comprise a first sub-pixel column and a second sub-pixel column; the sub-pixels located between the first breakpoint b1 and the pad end in the first sub-pixel column are connected to the first sub-data line, and the sub-pixels located between the first breakpoint b1 and the far end of the pad in the first sub-pixel column are connected to the second sub-data line; the second sub-data line and the second data line D m-4 are connected to the repair line W3, the second data line D m-4 The sub-pixels in the second sub-pixel column are connected.

[0044] Specifically, the first data line D m-1 The first data signal is transmitted along the pad end to the pad far end. m-1 When a circuit break occurs at the first breakpoint b1, the first sub-data line between the first breakpoint b1 and the pad end can transmit the first data signal normally, and the sub-pixels in the first sub-pixel column between the first breakpoint b1 and the pad end receive the first data signal to emit light for display. However, the second sub-data line between the first breakpoint b1 and the far end of the pad cannot transmit the first data signal. The second data line D m-4 The second data signal is transmitted along the pad end to the pad distal end to the sub-pixel in the second sub-pixel column. m-4 are connected to the repair line W3, so that the second sub-data line receives the second data line D m-4 The second data signal transmitted is transmitted to the sub-pixel located between the first breakpoint b1 and the far end of the pad in the first sub-pixel column, thereby m-1 Repair completed.

[0045] In this embodiment, by connecting the second sub data line and the second data line D m-4 The second sub-data line that cannot transmit data signals normally due to line breakage can be connected to the second data line D m-4The data signal in the display can avoid obvious bright and dark line defects, and repair the abnormal circuit break of the data line, which is further beneficial to improving the yield of the display panel.

[0046] Optionally, based on the above embodiments, the sub-pixels in the first sub-pixel column and the second sub-pixel column are arranged in the same manner. Preferably, the first sub-pixel column and the second sub-pixel column are arranged at intervals.

[0047] Specifically, the second sub-data line is connected to the second data line D m-4 The transmitted data signal controls the sub-pixels located between the first breakpoint b1 and the far end of the pad in the first sub-pixel column to emit light for display, so that the color and brightness of some sub-pixels in the first sub-pixel column are consistent with those of sub-pixels in the second sub-pixel column. In order to make the display area where the first sub-pixel column is located display uniformly, the arrangement of sub-pixels in the first sub-pixel column and the second sub-pixel column is set to be the same. Exemplarily, the color and layout of sub-pixels in the first sub-pixel column and the second sub-pixel column are consistent. Preferably, the first sub-pixel column and the second sub-pixel column are arranged at intervals to avoid signal crosstalk.

[0048] In this embodiment, by setting the sub-pixels in the first sub-pixel column and the second sub-pixel column to have the same arrangement, obvious display defects can be avoided, which is beneficial to improving the yield of the display panel.

[0049] Figure 6 FIG. 1 is a schematic diagram of the structure of a display panel provided by another embodiment of the present application. Figure 6 As shown, the array substrate also includes a scan line, which extends along the second direction y; the first sub-data line has a second breakpoint b2, and the first sub-data line includes an invalid data line located between the first breakpoint b1 and the second breakpoint b2, and a valid data line located between the second breakpoint b2 and the pad end, the invalid data line is electrically connected to the scan line, and the valid data line is connected to a sub-pixel in the first sub-pixel column located between the second breakpoint b2 and the pad end.

[0050] Specifically, the scan line may include one or more. Exemplarily, the array substrate includes a plurality of scan lines G1, G2, G3 and G4, and the plurality of scan lines are arranged sequentially along the first direction x. Each scan line in the array substrate is connected to the gate of the switching transistor of the sub-pixel connected thereto. When the first sub-data line is electrically connected to the scan line, the sub-pixel connected to both the first sub-data line and the scan line is short-circuited, causing display abnormality. At this time, a second breakpoint b2 is formed on the first sub-data line, and the data line between the first breakpoint b1 and the second breakpoint b2 becomes an invalid data line. The valid data line between the second breakpoint b2 and the pad end normally transmits data signals to the sub-pixels in the first sub-pixel column located between the second breakpoint b2 and the pad end.

[0051] In this embodiment, the array substrate includes a scan line, and the electrical connection between the scan line and the first sub-data line will cause a short circuit in the sub-pixel connected to the scan line in the first sub-pixel column. By forming a second breakpoint b2 on the first sub-data line, the data line between the first breakpoint b1 and the second breakpoint b2 is invalidated, and the remaining part can be repaired by the repair line W3 and then transmit the data signal, thereby realizing the repair of the short circuit abnormality of the data line, which is further beneficial to improving the yield of the display panel.

[0052] Figure 7 The figure shows a flow chart of a method for repairing a display panel provided by an embodiment of the present application. The method is applicable to the display panel mentioned in any of the above embodiments. The multiple data lines in the display panel include a first data line and a second data line. The multiple sub-pixel columns include a first sub-pixel column and a second sub-pixel column. The sub-pixels in the first sub-pixel column are connected to the first data line, and the sub-pixels in the second sub-pixel column are connected to the second data line. Figure 7 As shown, the repair method includes:

[0053] S110, when the first data line has a first breakpoint and the first data line is divided into a first sub-data line located between the first breakpoint and the pad end and a second sub-data line located between the first breakpoint and the far end of the pad, the second sub-data line and the repair line, and the second data line and the repair line are welded.

[0054] Specifically, when the first data line has a first breakpoint, that is, the first data line has a circuit break abnormality, the appearance of the first breakpoint causes the first data line to be divided into a first sub-data line located between the first breakpoint and the pad end, and a second sub-data line located between the first breakpoint and the far end of the pad. The second sub-data line and the repair line, and the second data line and the repair line are welded, so that the second sub-data line and the second data line are connected, the second sub-data line receives the second data signal transmitted by the second data line, and transmits it to the sub-pixel located between the first breakpoint and the far end of the pad in the first sub-pixel column, thereby completing the repair of the abnormal first data line.

[0055] Figure 8 FIG. 1 is a schematic diagram of a cross-sectional structure of an array substrate provided in an embodiment of the present application. Figure 8 As shown, the array substrate includes a data line layer DL, an insulating layer INS and a repair line layer WL arranged in sequence on one side of the substrate 100. The data line layer DL and the repair line layer WL are both made of metal materials. When an abnormality occurs in the data line, the data line and the repair line W3 are welded, that is, the data line layer DL and the repair line layer WL are welded together at a preset position.

[0056] The technical solution of this embodiment is to fuse the second sub-data line and the repair line, and the second data line and the repair line, when the first data line has a first breakpoint and the first data line is divided into a first sub-data line located between the first breakpoint and the pad end and a second sub-data line located between the first breakpoint and the far end of the pad, so that when the first data line is broken, the normal second data line is connected to the abnormal first data line by the repair line. In this way, the area on the abnormal data line that cannot transmit signals normally can access normal data signals, avoiding obvious bright and dark line defects, and realizing the repair of the abnormal break of the data line, and further improving the yield of the display panel.

[0057] Fig. 9 The figure shows a flow chart of a display panel repair method provided by another embodiment of the present application. The method is applicable to the display panel mentioned in any of the above embodiments. The multiple data lines of the display panel include a first data line and a second data line. The multiple sub-pixel columns include a first sub-pixel column and a second sub-pixel column. The sub-pixels in the first sub-pixel column are connected to the first data line, and the sub-pixels in the second sub-pixel column are connected to the second data line. The array substrate also includes a scan line, and the scan line extends along the second direction. Fig. 9 As shown, the repair method includes:

[0058] S210, when the first data line and the scan line are short-circuited, the first data lines on both sides of the short-circuit point are cut off to form a first breakpoint and a second breakpoint.

[0059] Specifically, when the first data line is electrically connected to the scan line, the sub-pixel connected to both the first data line and the scan line is short-circuited, that is, the first data line and the scan line are short-circuited. In the case where the first data line and the scan line are short-circuited, the first data line on both sides of the short-circuit point is cut off, and a first breakpoint and a second breakpoint are formed on the first data line. In this way, the short-circuit phenomenon between the first data line and the scan line disappears, and at the same time, the first data line is broken, and the first data line can be connected to the normal data line through the repair line to achieve repair of the first data line.

[0060] S220, when the first data line is divided into a valid data line located between the second breakpoint and the pad end, an invalid data line located between the first breakpoint and the second breakpoint, and a second sub-data line located between the first breakpoint and the far end of the pad, the second sub-data line and the repair line, and the second data line and the repair line are welded.

[0061] Specifically, when the first data line has a first breakpoint and a second breakpoint, the first data line is divided into a valid data line between the second breakpoint and the pad end, an invalid data line between the first breakpoint and the second breakpoint, and a second sub-data line between the first breakpoint and the far end of the pad. The second sub-data line and the repair line, and the second data line and the repair line are fused so that the second sub-data line and the second data line are connected, the second sub-data line receives the second data signal transmitted by the second data line, and transmits it to the sub-pixel in the first sub-pixel column between the first breakpoint and the far end of the pad, thereby completing the repair of the abnormal first data line.

[0062] Fig.10 FIG. 2 is a schematic diagram of a cross-sectional structure of an array substrate provided by another embodiment of the present application. Fig.10 As shown, when a short circuit abnormality occurs in the data line, the data lines on both sides of the short circuit point are cut off, that is, the data line layer DL is melted at a preset position to form a breakpoint.

[0063] The technical solution of this embodiment can eliminate the short circuit phenomenon by cutting off the first data lines on both sides of the short circuit point when the first data line and the scan line are short-circuited. In this way, the first breakpoint and the second breakpoint are formed on the first data line. When the first data line is divided into a valid data line between the second breakpoint and the pad end, an invalid data line between the first breakpoint and the second breakpoint, and a second sub-data line between the first breakpoint and the far end of the pad, the second sub-data line and the repair line, and the second data line and the repair line are welded, and the first data line can be repaired by using the repair line. This arrangement realizes the repair of the short circuit anomaly of the data line, and further improves the yield of the display panel.
