The embodiment of the application provides an array substrate and a display panel, and the detailed description is given below. The following description of the embodiments is not intended to limit the preferred embodiments.
Referring to fig. 1, a first embodiment of the present application provides an array substrate 100, which includes a plurality of first signal lines 11, a plurality of GOA units 12, a plurality of repair lines 13, and at least one driver 14.
Each first signal line 11 is connected to a Scan line Scan.
The signal output terminal OUT of each GOA unit 12 is correspondingly connected to a first signal line 11.
The repair line 13 is used for connecting the first signal line 11 corresponding to the failed GOA unit 12. The repair line 13 is arranged in a different layer from the first signal line 11. The repair line 13 is disposed to intersect the first signal line 11.
The driver 14 is connected to the plurality of repair lines 13.
In the array substrate 100 of the first embodiment of the present application, the signal output terminal OUT of each GOA unit 12 is correspondingly connected to a first signal line 11. The repair line 13 is used for connecting the first signal line 11 corresponding to the failed GOA unit 12; the driver 14 provides the repair line 13 with a corresponding GOA signal. The first embodiment is provided with a repair line 13 and a driver 14 connected to the repair line 13, and uses the repair line 13 to connect to the first signal line 11 corresponding to the failed GOA unit 12, so as to solve the problem of abnormal display caused by the failure of the GOA unit 12.
It should be explained that a failed GOA unit means that the GOA unit does not send out a GOA signal or that the sent GOA signal is abnormal.
Alternatively, referring to fig. 1 and 2, the first signal line 11 includes a signal main line 111 and a signal sub line 112 connected to one side of the signal main line 111. The signal main line 111 is connected to the GOA unit 12 and the Scan line Scan.
The repair line 13 includes a repair main line 131 and a repair sub-line 132 connected to the repair main line 131. The repair main line 131 is disposed to intersect the signal main line 111. Repair sub-line 132 is used to connect with signal sub-line 112.
Optionally, the extension direction of the repair main line 131 is perpendicular to the extension direction of the signal main line 111. In some embodiments, the extension direction of the repair main line 131 and the extension direction of the signal main line 111 may not be perpendicular.
The first embodiment adopts the repair sub-line 132 and the signal sub-line 112 as repair connection lines, so as to avoid secondary abnormality caused by laser damage to the signal main line 111 and the repair main line 131.
In some embodiments, the repair line 13 may include only the repair main line 131, and the first signal line 11 may include only the signal main line 111. The arrangement is such that the repair portion will be at the intersection area of the repair line 13 and the first signal line 11.
Alternatively, in the first embodiment, a signal main line 111 is connected to a plurality of signal sub-lines 112 arranged at intervals. In one first signal line 11, each signal sub-line 112 corresponds to a repair sub-line 132 of one repair line 131.
Optionally, a repair main line 131 is connected to a plurality of repair sub-lines 132 that are disposed at intervals. In one repair line 13, each repair sub-line 132 corresponds to a signal sub-line 112 of the first signal line 11.
In the array substrate 100 of the first embodiment, a repair sub-line 132 and a signal sub-line 112 corresponding thereto form a repair unit XF, as shown in fig. 2; by adopting the repairing mode that each first signal line 11 corresponds to a plurality of repairing units XF, once repairing of one repairing unit XF fails, the repairing main line 131 and the signal main line 111 can still normally transmit signals, so that repairing can be performed by adopting another repairing unit XF, and the repairing success rate is improved.
Optionally, in the front view pattern (fig. 1) of the array substrate 100, the free ends of the repair sub-lines 132 are spaced apart from the free ends of the signal sub-lines 112.
The front view pattern of the array substrate 100 is a front projection pattern of the plane of the array substrate 100. The free end refers to the end to which no component is attached.
Optionally, in the front view pattern of the array substrate 100, the extending direction of the repair sub-line 132 coincides with the extending direction of the signal sub-line 112. The free end of the repair sub-line 132 is disposed opposite the free end of the signal sub-line 112. The arrangement saves the repair distance and reduces the repair difficulty.
Optionally, the array substrate 100 further includes a second signal line 15 and a third signal line 16.
The signal output terminal OUT of the n-th GOA cell 12 is connected to the signal input terminal IN of the n+k-th GOA cell 12. The signal output terminal OUT of the n+kth row GOA unit 12 is connected to the signal RESET terminal RESET of the n+kth row GOA unit 12 and the signal input terminal IN of the n+2kth row GOA unit 12, n and k being positive integers.
The second signal line 15 is connected to the first signal line 11 and the signal input terminal IN of the GOA unit 12. The third signal line 16 is connected to the first signal line 11 and the signal RESET terminal RESET of the GOA unit 12.
Wherein the first signal line 11 is provided with a disconnection region DK adjacent to the signal output terminal OUT of the GOA unit 12. The disconnection region DK is used to disconnect the output path of the failed GOA unit 12.
When the GOA unit 12 fails, the repair of the line is required in the corresponding repair unit XF to ensure continuity of GOA signal transmission. In order to avoid the repaired GOA pathway from being interfered by the failed GOA unit 12, a cutting process may be performed in the disconnection region DK of the first signal line 11 to disconnect the GOA signal pathway of the failed GOA unit 12.
It should be noted that, even if the GOA signal path of the failed GOA unit 12 is disconnected, the second signal line 15 and the third signal line 16 are still respectively connected to the first signal line 11, so as to ensure the normal output of the GOA signal of each stage.
Optionally, the array substrate 100 includes a substrate Jb, a first metal layer Fj, a first insulating layer Fy, a second metal layer Sj, and a second insulating layer Sy, where the first metal layer Fj, the first insulating layer Fy, the second metal layer Sj, and the second insulating layer Sy are sequentially disposed on the substrate Jb.
The first metal layer Fj includes a repair line 13 and a Scan line Scan. The second metal layer Sj includes a first signal line 11, a second signal line 15, and a third signal line 16.
In some embodiments, the repair line 13 may be at the second metal layer Sj, and the first signal line 11 may be at the first metal layer Fj.
In some embodiments, the second signal line 15 and the third signal line 16 may be formed at the first metal layer Fj or the second metal layer Sj, respectively.
Optionally, the array substrate 100 of the first embodiment includes a display area AA and a non-display area NA disposed at one side of the display area AA.
The multiple GOA units 12 are disposed on the non-display area NA. A plurality of repair lines 13 are disposed in the non-display area NA. The plurality of first signal lines 11 are also disposed in the non-display area NA.
Wherein the second metal layer Sj further includes a data line. The Scan lines Scan and the data lines are disposed in the display area AA. It should be noted that the display area AA of the array substrate 100 refers to an area for corresponding to a display function.
Referring to fig. 3, when the GOA unit 12 fails in the array substrate 100 of the first embodiment, the first embodiment is illustrated by taking the GOA unit 12 failure as an example, but is not limited thereto.
The repair process of the array substrate 100 of the first embodiment is: finding a failed GOA unit 12, and finding a first signal line 11 connected to the failed GOA unit 12; subsequently, a repair unit XF is selected to repair, so that the repair sub-line 132 and the signal sub-line 112 are electrically connected; finally, the connection path of the first signal line 11 to which the GOA unit 12 is connected is disconnected, that is, a cutting operation is performed in the disconnection region DK of the first signal line 11.
Alternatively, the repairing of the repairing unit XF and the cutting process in the disconnection area DK may be performed in a laser manner.
Referring to fig. 4, after the repair is completed, the repair line 13 outputs a normal Gn level signal and level transmission through the driver 14.
Referring to fig. 5 and 6, the array substrate 200 of the second embodiment is different from the array substrate 100 of the first embodiment in that: the repair sub-line 132 at least partially overlaps the signal sub-line 112. This arrangement allows the repair points to be placed at the overlap of the repair sub-line 132 and the signal sub-line 112, thereby further shortening the repair distance and reducing the repair difficulty.
The array substrate 200 of the second embodiment is identical or similar to the array substrate 100 of the first embodiment, and specific reference may be made to the content of the array substrate 100 of the first embodiment. The repair process of the array substrate 200 of the second embodiment is the same as or similar to the repair process of the array substrate 100 of the first embodiment, and specific reference may be made to the description of the repair process of the array substrate 100 of the first embodiment.
Referring to fig. 7, the array substrate 300 of the third embodiment is different from the array substrate 100 of the first embodiment in that: the array substrate 300 includes a display area AA, a first non-display area NA1 disposed at a first side of the display area AA, and a second non-display area NA2 disposed at a second side of the display area AA. The first side and the second side are disposed opposite.
The plurality of GOA units 12 includes a plurality of first GOA units 12a and a plurality of second GOA units 12b. The plurality of first GOA units 12a are disposed in the first non-display area NA1. The plurality of second GOA units 12b are disposed in the second non-display area NA2.
