An embodiment of the present application provides a display panel, referring to fig. 1, showing a film layer structure 500 of an overlapping region, referring to the film layer structure 500 of the overlapping region, the display panel includes: a first metal layer 100, an insulating layer 200, a second metal layer 300, and a reflective layer 400.
The insulating layer 200 is located at one side of the first metal layer 100.
The second metal layer 300 is located on a side of the insulating layer 200 away from the first metal layer 100, and there are at least two overlapping areas between the orthographic projection of the second metal layer 300 on the insulating layer 200 and the orthographic projection of the first metal layer 100 on the insulating layer 200; the overlap region includes at least one solder joint region 510.
The reflective layer 400 is located on a side of the second metal layer 300 away from the first metal layer 100, and the reflective layer 400 is used to reflect laser light incident from the first metal layer 100 during the process of connecting the first metal layer 100 and the second metal layer 300 at the solder joint region 510 to form a solder joint structure.
The inventor of the present application considers that the existing laser welding often causes the defect of other film structures when the laser passes through the second metal layer 300 to other film structures of the display panel, and the laser beam is injected into the other film layers to cause the low utilization rate of the laser, so that the welding quality of the welding spot quality cannot be ensured, and the problem of incomplete repair or low repair efficiency of the display panel is caused.
Based on the above consideration, the reflective layer 400 in the embodiment of the present application can reflect the laser emitted from the first metal layer 100, so as to increase the utilization efficiency of the welding spot to the laser energy during Repair, ensure the welding quality of the welding spot structure formed by connecting the first metal layer 100 and the second metal layer 300, avoid the problem of incomplete Repair or low Repair efficiency of the display panel, and improve the production yield of the display panel.
Meanwhile, the reflection layer 400 of the embodiment of the application reflects laser, avoids bad occurrence of products caused by laser transmission to other structures of the display panel, namely reduces other bad caused by welding, and ensures the production yield of the display panel.
Optionally, referring to fig. 2, the overlap region of the embodiments of the present application includes at least one solder joint region 510. The first metal layer 100 and the second metal layer 300 are sintered and connected in a pad region 510 (shown as a dotted line in the drawing) to form a welded structure, so that the first metal layer 100 and the second metal layer 300 are electrically connected, and an electrical signal of the second metal layer 300 can be output to the first metal layer 100.
In some embodiments, the reflective layer 400 is part of an anode layer of a display panel.
Optionally, when preparing the anode layer structure of the light-emitting layer, a MASK is used to etch the anode layer to obtain the anode structure. The anode layer can reflect laser, so that a part of the anode layer which needs to be etched in an original overlapping area is reserved in the process of preparing the anode layer, and the part of the anode layer is used as the reflecting layer 400, so that the problems of improving the laser utilization rate and preventing other bad occurrence can be realized by directly utilizing the anode layer without additionally arranging the reflecting layer 400, and the process is simple.
In some embodiments, the second metal layer 300 includes a plurality of data signal lines 310 arranged at intervals.
Alternatively, the data signal line 310 is broken, and the data signal cannot be output to the data signal line 310, resulting in a bright line when the display panel is black.
Optionally, the break of the data signal line 310 is located between two adjacent overlapping regions, and the welding spot region 510 of the two adjacent overlapping regions is laser welded, so that the data signal can be output from the two adjacent overlapping regions to the break through the first metal layer 100, thereby avoiding bright lines when the display panel is black.
Alternatively, the first metal layer 100 is a bottom metal, and may be made of the same material as the data signal line 310 or another metal conductive material.
Alternatively, the insulating layer 200 may be a semiconductor dielectric material such as oxynitride, and may be an inorganic layer.
Alternatively, the thicknesses of the first metal layer 100, the insulating layer 200, the second metal layer 300, and the reflective layer 400 in the direction perpendicular to the substrate of the display panel are all 0-1 μm.
The embodiment of the application uses the high reflectivity of the anode layer to reflect the laser which is transmitted through the data signal line 310 again, so as to improve the absorption efficiency of the welding spot area 510 to the laser energy, improve the welding speed, and reduce the thermal influence range.
In some embodiments, referring to fig. 3, the first metal layer 100 includes a first metal structure 110 and a second metal structure 120. There is an overlap region of each data signal line 310 with the first metal structure 110, and there is an overlap region of each data signal line 310 with the second metal structure 120. The first metal structure 110 and the second metal structure 120 are located outside the display area 600, so that damage to the display area 600 caused by welding the first metal structure 110 and the second metal structure 120 can be avoided.
Specifically, the structure of the display panel of the embodiment shown in fig. 3 to 5 is a view angle structure diagram from the laser welding side.
Alternatively, as shown in fig. 3, a portion of the anode layer at the periphery of the display region 600 serves as the reflective layer 400.
In some embodiments, referring to fig. 3, as an example, portions of the first metal structure 110 corresponding to respective overlapping regions are electrically connected; in the second metal structure 120, portions corresponding to the overlapping regions are electrically connected.
Alternatively, as shown in fig. 3, the first metal structure 110 and the second metal structure 120 are two structures arranged at intervals, and the first metal structure 110 and the second metal structure 120 are two complete continuous structures, that is, the first metal structure 110 and the second metal structure 120 can be only welded once and electrically connected to the same data signal line 310, thereby repairing the break on the data signal line 310.
Alternatively, referring to fig. 3, the first and second metal structures 110 and 120 are each disposed along a first direction, and the data signal lines 310 are disposed along a second direction, the first and second directions being perpendicular.

Referring to fig. 4, the left side of the display panel is a left screen, the right side is a right screen, and two first sub-metal structures 111 and two second sub-metal structures 121 are respectively located on the left screen and the right screen. When the bright line appears on the left screen, two overlapping areas at the data signal line 310 corresponding to the bright line appear on the left screen are required to be welded, and when the bright line appears on the right screen, two overlapping areas at the data signal line 310 corresponding to the bright line appear on the right screen are required to be welded. Thus, the whole display panel can be divided into two blocks, and the repair can be carried out twice.

Referring to fig. 5, the left side of the display panel is a left screen, the middle is a middle screen, the right side is a right screen, and three first sub-metal structures 111 and three second sub-metal structures 121 are respectively located on the left screen, the middle screen and the right screen. When the bright line appears on the left screen, two overlapping areas at the data signal line 310 corresponding to the bright line appear on the left screen are required to be welded; when the bright line appears on the middle screen, two overlapping areas at the data signal line 310 corresponding to the bright line appear on the middle screen are required to be welded; when the bright line appears on the right screen, two overlapping areas at the data signal line 310 corresponding to the bright line appears on the right screen need to be welded.
