Specifically, the display panel may include a substrate on which each pixel is disposed, and the middle area a3 may be a hollow area of the substrate. In a specific implementation process, the connection lines may be connected in a winding manner to connect the scanning signal lines 03 in the first sub-region a1 with the scanning signal lines 03 in the second sub-region a2 in a one-to-one correspondence manner on the sides of the first sub-region a1, the second sub-region a2, and the second display region B close to the middle region A3, as shown by the connection lines indicated by dashed lines in fig. 4.

Optionally, the display panel provided in the embodiment of the present invention may have a structure with multiple metal layers, and components essential to the display panel and position structures of the components are all understood by those skilled in the art, and are not described herein again.
In the following description of the embodiments of the present invention, a three-metal layer structure of an OLED display panel is mainly taken as an example for detailed description, and the display panel includes a first metal layer, a second metal layer and a third metal layer from bottom to top. Each row of pixel circuits 01 may be provided in the same metal layer or in different metal layers. For example, the gate is on the first metal layer, the capacitor connected to the gate is on the second metal layer, and the drain is on the third metal layer, however, other setting manners may be provided in the specific implementation process, and a person skilled in the art may select the setting manner according to the actual situation, and the specific setting manner of the pixel circuit 01 is not specifically limited in the embodiment of the present invention.
Correspondingly, each row of the scanning signal lines 03 may be on the same metal layer or on different metal layers, and the embodiment of the present invention is not limited specifically.
The following exemplifies several possible wiring schemes of the present invention:
the 1 st: the scanning signal line 03 and the connection line are located on the same metal layer.
For example, referring to fig. 5, assuming that the scanning signal lines 03 are all in the first metal layer, a connection line metal 1 may be disposed directly on the first metal layer, and metal 1 may be routed to connect the disconnected scanning signal lines 03 in each row at the periphery of the middle area a 3.
The 2 nd: the scan signal line 03 and the connection line are not entirely located in the same metal layer.
When the scanning signal line 03 and the connection line which need to be electrically connected are located on different metal layers, the two lines can be connected in a punching mode or a jumper mode.
For example, referring to fig. 6, the scan signal lines 03 are all located in a first metal layer, a portion of the connection line metal 1 is located in the first metal layer, and another portion of the connection line metal2 is located in a second metal layer, and metal 1 and metal2 for connecting the same row of scan signals are electrically connected through a via 04 between the first metal layer and the second metal layer. In the specific implementation process, the hole can be directly punched from the first metal layer to the second metal layer, and the metal filling is performed on the via hole 04 by using the metal melted in the punching process, so that the metal 1 and the metal2 are electrically connected.
For another example, referring to fig. 7, the scan signal line 03 is located in the first metal layer, and a portion of the connection line metal 1 is located in the first metal layer; the other part of the connecting wire metal2 is located in the second metal layer, and metal 1 and metal2 are electrically connected through the jumper wire metal 3 located in the third metal layer, so that metal 1 is connected with the scanning signal line 03 of the first metal layer.
By the mode, the manufacturing process can be simplified, the manufacturing cost is saved, and the design of the position structure of the original part of the display panel is not influenced.
Alternatively, the connection lines located in the first metal layer and the connection lines located in the second metal layer are alternately arranged in a column direction, as shown in fig. 8. The connection between the connection line metal2 of the second metal layer and the scan signal line 03 of the first metal layer can be implemented by referring to the above-mentioned schemes, and details are not repeated here, and the connection between the metal2 and the scan signal line 03 is implemented by the jumper metal 3 of the third metal layer in the manner shown in fig. 8.
This embodiment can make the wiring more compact and reduce the width occupied by the intermediate area a3, which is a non-display area, on the display panel. For example, the minimum line distance between two adjacent signal lines in the same metal layer is 3um, the line width is 2um, and if there are 50 signal lines, the width of the frame is 50 × 2+3 × 49 — 247um, if the above-mentioned double-layer arrangement scheme of the embodiment of the present invention is adopted, the minimum line distance between two adjacent signal lines may be reduced to 1um, and the width of the frame is only 50 × 2+49 — 1 — 149 um.
Optionally, the display panel further includes a package region, the package region includes a package metal layer, and at least a portion of the connection line is multiplexed with the package metal layer.
Specifically, each metal layer of the display panel is provided with a packaging area, and the packaging area is generally made of a metal material and is mainly used for packaging and fixing each metal layer and an insulating layer of the display panel and reflecting laser light, so that the utilization rate of the laser light is improved. For example, fig. 9 is a schematic structural diagram of the first metal layer, and the package metal 05 is disposed at the outer edge of the middle area a 3.
In view of this, in combination with the above-mentioned solution of disposing the connecting wires at the outer edge of the intermediate region A3, the connecting wires can be directly fabricated on the first metal layer by using the package metal 05 disposed at the outer edge of the intermediate region A3, as shown in fig. 10, so that the connecting wires and the package metal layer are an integral structure. Of course, if there are connection lines disposed on other metal layers, the connection lines may be made by using the package metal 05 on the other metal layers accordingly, and the embodiment of the invention is not limited in particular.
Generally, the first metal layer and the second metal layer of the existing OLED are coated with inorganic layers, so the adhesion of the encapsulation metal 05 on the first metal layer and the second metal layer is better than that of the encapsulation metal 05 on the third metal layer, so in a specific implementation process, it may be considered to preferentially use the encapsulation metal 05 on the first metal layer and/or the second metal layer on which the inorganic layers are disposed to make the connection line, and the making manner may refer to the manner shown in fig. 10, and is not described here again.
Through this mode, with the multiplexing encapsulation metal level of connecting wire, can make the connecting wire play the effect of reflection laser on the one hand, improve the laser utilization ratio, on the other hand makes the connecting wire need not additionally occupy the area of frame, further reduces the shared width of non-display area on display panel.
Optionally, in order to obtain a better display effect, in the embodiment of the present invention, each of the scanning signal lines 03 may be connected to a compensation capacitor in the first display area a, so as to compensate for the missing load in the middle area a 3.
Specifically, the compensation capacitor includes a first electrode and a second electrode, and the compensation capacitor may at least partially overlap the connection line in a direction perpendicular to the display panel. For example, the first electrode and the connecting wire may be an integral structure, and the second electrode is connected to a fixed potential 02 signal wire. The fixed potential 02 signal line may be a power voltage signal line, a reference signal line or a common voltage signal line, and the like, which is not limited in the embodiments of the present invention.
In the specific implementation process, the second electrode and the first electrode are arranged on different metal layers, and an insulating layer between the different metal layers can be directly used as a medium for supplementing the capacitor.
For example, when the connection line is located in the first metal layer, the second electrode may be disposed in the second metal layer or the third metal layer, and the second electrode is connected to the power supply voltage signal line or the reference signal line or the common voltage signal line, so that the compensation capacitor may be disposed.
Further, in combination with the scheme that the connection line multiplexes the package metal 05 layer, the second electrode can be directly manufactured by using the package metal 05 on the second metal layer or the third metal layer in the specific implementation process of the present invention. For example, as shown in fig. 11, the connecting wires may be distributed on the first metal layer and the second metal layer, and the setting of the compensation capacitor can be realized only by connecting the package metal 3 of the third metal layer with the fixed potential 02.
By the mode, the circuit load missing in the middle area A3 can be compensated, and the problem of uneven display of the display panel is further improved; meanwhile, the capacitor electrode is manufactured by multiplexing the metal layer packaging metal 05, so that the manufacturing process can be further simplified, and the manufacturing cost is saved.
Optionally, the edge profile of the middle area a3 is a circular arc. Through the mode, the display panel is more attractive in appearance, and the user experience is improved.
Optionally, the first sub-region a1 is arranged symmetrically to the second sub-region a 2. Through the mode, the display panel is more attractive in appearance, and the user experience is improved.
