[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0040] Figure 1 The following is a schematic diagram of the structure of a display panel provided by the prior art. Figure 1 As shown, the display panel includes a main screen 101, a sub-screen 102 and a driving chip 103. The main screen 101 is circular in shape, and the sub-screen 102 is strip-shaped and arranged around the main screen 101. The main screen 101 is arranged between the sub-screen 102 and the driving chip 103. When the driving chip 103 provides a driving signal for the sub-screen 102, the driving signal line for transmitting the driving signal passes through the main screen 101 and extends to the sub-screen 102 to provide the driving signal for the sub-screen 102. The main screen 101 is not only set as a driving signal line for transmitting the driving signal itself, but also set as a driving signal line for transmitting the driving signal for the sub-screen 102, and other wirings, so that the main screen 101 needs to be set with more signal lines. When the area of ​​the main screen 101 is fixed, it is not conducive to the wiring of the display panel; in addition, with the continuous development of technology, the requirements for display panels are getting higher and higher, such as display panels with high resolution, but the higher the resolution of the product, the more signal lines it needs, which is not conducive to the wiring of the display panel when the area of ​​the main screen 101 is fixed.

[0041] In view of the above technical problem, an embodiment of the present invention provides a display panel. Figure 2 A schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Figure 3 FIG. 1 is a schematic diagram of a cross-sectional structure of a display panel provided by an embodiment of the present invention. Figure 2 and Figure 3 As shown, the display panel includes a first area A and a second area B; a first pixel P1 is disposed in the first area A, and the first pixel P1 is electrically connected to a first signal line 121 located in the first area A, and a second pixel P2 is disposed in the second area B;

[0042] The display panel also includes:

[0043] Base 110;

[0044] The first conductive layer 130 is arranged on one side of the substrate 110 and is located in the second area B. The first conductive layer 130 includes a plurality of first partition structures 131 and at least one first connecting line 132. The first partition structure 131 and the first connecting line 132 are arranged on the same layer. The first partition structure 131 has a plurality of first isolation openings. The second pixel P2 is located in the first isolation opening. The first connecting line 132 is electrically connected to the first signal line 121.

[0045] Specifically, the substrate 110 may include a flexible substrate. Exemplarily, the material of the flexible substrate may be polyimide. By setting the substrate 110 to include a flexible substrate, it is beneficial to bend the display panel, so that it is convenient to set the shape of the first area A and the second area B according to the application scenario of the display panel. For example, when the display panel is applied to an electronic watch, the first area A may be circular, as the main screen of the electronic watch, and the second area B may be annular, as the secondary screen of the electronic watch. Alternatively, the second area B may be circular, as the main screen of the electronic watch, and the first area A may be annular, as the secondary screen of the electronic watch, and both the main screen and the secondary screen may be displayed synchronously; the substrate 110 may also include a driving circuit layer, the driving circuit layer is located on the substrate, and the driving circuit layer is used to form a pixel driving circuit, and the pixel driving circuit is electrically connected to the pixel, so as to drive the light-emitting layer of the pixel to emit light. Exemplarily, the pixel driving circuit formed by the driving circuit layer located in the first area A is electrically connected to the first pixel P1, and is used to drive the first pixel P1 to emit light. The pixel driving circuit formed by the driving circuit layer located in the second area B is electrically connected to the second pixel P2, and is used to drive the second pixel P2 to emit light. The driving circuit layer is provided with multiple conductive layers. In the first area A, the first signal line 121 is provided in at least one conductive layer. The first signal line 121 can be directly electrically connected to the first pixel P1, and can also be indirectly electrically connected to the first pixel P1; thereby providing a corresponding signal to the first pixel P1 through the first signal line 121 to control its light emission. Exemplarily, the first signal line 121 may include a data signal line, a power signal line, and an initialization signal line. In this case, the first signal line 121 may be directly electrically connected to the first pixel P1 to provide the first pixel P1 with a data signal, a power signal, and an initialization signal. The first signal line 121 may also include a gate drive signal line. In this case, the first signal line 121 may be electrically connected to the first pixel P1 through a gate drive circuit to provide a gate drive signal to the first pixel P1. In addition, the second area B may also include a signal line, which is also provided in the driving circuit layer and is electrically connected to the second pixel P2 to provide a signal to the second pixel P2. Exemplarily, the structures of the first pixel P1 and the second pixel P2 may be the same, and the signal line in the second region B is of the same type as the first signal line 121 in the first region A and may be disposed in the same layer.

[0046] The first partition structure 131 is located around the second pixel P2 and is electrically connected to the second pixel P2 for providing a power signal to the second pixel P2. Figure 4 FIG. 1 is a schematic diagram of a partial cross-sectional structure of a first partition structure provided by an embodiment of the present invention. Figure 4 As shown, the first partition structure 131 includes a connecting portion 1311 and a hanging portion 1312; the connecting portion 1311 is arranged on one side of the substrate 110, and the hanging portion 1312 is arranged on the side of the connecting portion 1311 away from the substrate 110, and the orthographic projection of the hanging portion 1312 on the substrate 110 is larger than the orthographic projection of the connecting portion 1311 on the substrate 110, thereby forming a hanging structure on the connecting portion 1311. The connecting portion 1311 can be a conductive structure. When electrically connected to the second pixel P2, it can be electrically connected to the second pixel P2 through the connecting portion 1311. This structural design can improve the resolution without using a precision mask when evaporating the organic light-emitting layer.

[0047] In some embodiments, the display panel further includes a pixel definition layer 122, the pixel definition layer 122 is located on one side of the substrate 110, and the first conductive layer 130 is located on the side of the pixel definition layer 122 away from the substrate 110; in the process of manufacturing the display panel, the connection portion 1311 can be arranged on the pixel definition layer 122 and located around the pixel opening area E. A light-emitting device is arranged in the pixel opening area E, that is, a pixel is located in the pixel opening area E, and the pixel includes a first pixel P1 and a second pixel P2. It is worth noting that the pixel can be a red pixel, a green pixel and a blue pixel, and of course it can also be other colors. Along the direction Z perpendicular to the substrate, the light-emitting device includes a stacked anode 123, a light-emitting layer 124 and a cathode 125. When manufacturing the light-emitting device, different evaporation angles can be matched to achieve that the light-emitting layer 124 is not overlapped with the connection portion 1311, and the cathode 125 is overlapped with the connection portion 1311, so as to achieve that the connection portion 1311 is electrically connected to the cathode 125 of the corresponding second pixel P2, so as to provide a power signal for the second pixel P2. It is worth noting that the connection portion 1311 in this embodiment can be a laminated structure, for example, a Mo metal layer and an Al metal layer stacked. The first conductive layer 130 also includes a first connection line 132, and the material of the first connection line 132 is the same as that of the first partition structure 131. That is, when the first partition structure 131 is formed, the first connection line 132 can be formed simultaneously; for example, the first connection line 132 can be a single-layer structure, that is, it can be formed simultaneously with the formation of any conductive film layer of the first partition structure 131; it can also be a laminated structure, that is, it is formed simultaneously in the process of forming the connection portion 1311 and the suspension portion 1312. In a preferred embodiment, the first connection line 132 is made of the same material as the connection portion 1311, that is, the first connection line 132 is formed simultaneously when the connection portion 1311 is formed. The first connection line 132 can be electrically connected to the first signal line 121 of the first area A, so that the first signal line 121 of the first area A can obtain the corresponding signal through the first connection line 132. When the display panel includes a driving unit, the driving unit may be disposed on a side of the second area B away from the first area A. In this case, the driving unit may provide a corresponding signal to the first pixel P1 of the first area A through the first connection line 132 .

[0048] The first connection line 132 is arranged in the same layer as the first partition structure 131, and the first connection line 132 does not need to be completely arranged in the corresponding film layer in the substrate 110, so that when the available wiring area of ​​the second area B is fixed, the wiring difficulty can be reduced, which is beneficial to the wiring of the display panel. Especially in a display panel with a higher resolution, the display panel requires more wiring, which is more conducive to wiring design. For example, Figure 5A schematic diagram of a planar structure of another display panel provided in an embodiment of the present invention. When the display panel is used for an electronic watch, the first area A can be the main screen, and the second area B can be the secondary screen. In this case, the first area A can be circular, and the second area B can be strip-shaped, and is arranged around the first area A to form a non-closed ring. The drive unit is arranged on the side of the second area B away from the first area A. The drive unit can be connected to the first signal line 121 through the first connecting line 132 of the secondary screen, so that the drive unit provides the first signal line 121 of the main screen with a corresponding signal through the first connecting line 132. On the basis of ensuring that the first pixel P1 obtains the corresponding signal, it is effectively avoided that all the wiring is arranged in the substrate of the secondary screen, thereby reducing the wiring requirements in the substrate of the secondary screen and reducing the wiring difficulty of the display panel. Alternatively, the first area A can be the secondary screen, and the second area B can be the main screen. In this case, the second area B can be circular, and the first area A can be strip-shaped, and is arranged around the second area B to form a non-closed ring. The drive unit can be arranged on the side of the second area B away from the first area A. The driving unit can be connected to the first signal line 121 through the first connecting line 132 of the main screen, so that the driving unit provides a corresponding signal to the first signal line 121 of the secondary screen through the first connecting line 132. The above structural design effectively reduces the wiring requirements of the substrate of the main screen and reduces the wiring difficulty of the display panel.

[0049] In the technical solution of this embodiment, a first connecting line is arranged on the first conductive layer, and the first connecting line is electrically connected to the first signal line. The driving unit of the display panel is arranged on a side of the second area away from the first area, and the driving unit provides a corresponding signal to the first pixel through the first connecting line to ensure that the first pixel displays normally. When the available area for wiring in the second area is constant, the difficulty of wiring is reduced, which is beneficial to the wiring of the display panel.

[0050] Based on the above technical solutions, Figure 6 A schematic diagram of a planar structure of a first conductive layer in a second region provided by an embodiment of the present invention, Figure 7 A schematic diagram of a planar structure of another display panel provided by an embodiment of the present invention. Figure 6 and Figure 7, the width of the second area B is smaller than the width of the first area A, the second area B serves as a secondary screen, and the second area B faces the driving unit, that is, is close to the driving unit, so that the length of the first connecting line 132 is relatively small. When the driving unit provides a corresponding signal to the first pixel P1 through the first connecting line 132, relative to the technical solution that the driving unit is arranged on the side of the first area away from the second area, and the connecting line is arranged in the first area to provide the corresponding signal to the second area, the impedance voltage drop of the signal on the line can be basically kept unchanged, thereby ensuring the accuracy of the first pixel acquiring the signal. At the same time, the driving unit can be directly electrically connected to the signal line of the second area to provide a signal to the second pixel. The above structural design can minimize the length of the signal passing through the line, thereby reducing the impedance voltage drop of the signal on the line, improving the accuracy of the signal acquired by the second pixel, and thus improving the display uniformity of the first area and the second area as a whole.

[0051] Continue to refer Figure 6 The first partition structure 131 is arranged around the second pixel P2, a plurality of first connection lines 132 are arranged, and at least one first connection line 132 is arranged between two adjacent first partition structures 131. In a preferred embodiment, in order to ensure the display effect, one first connection line 132 is arranged between two adjacent first partition structures 131.

[0052] Specifically, Figure 6 exemplarily shows that a first connection line 132 is provided between two adjacent first partition structures 131, which can ensure the distance between adjacent first connection lines 132, thereby reducing signal interference between different first connection lines 132, which is beneficial to improving the reliability of the display panel. In other embodiments, multiple first connection lines 132 can also be provided between two adjacent first partition structures 131.

[0053] When there are multiple first signal lines 121, there are multiple first connection lines 132, which are respectively connected to the first signal lines 121 to provide corresponding signals for different first signal lines 121. The first partition structure 131 can be electrically connected to the cathode contact to provide a power signal for the second pixel P2. The first connection line 132 is arranged between the first partition structures 131, so that the first connection line 132 extends between different second pixels P2, so as to prevent the first connection line 132 from affecting the light-emitting effect of the second pixel P2.

[0054] Continue to refer Figure 6 Optionally, the second pixels P2 are arranged in an array; the first connecting line 132 extends in a direction X from the second area B to the first area A.

[0055] Specifically, when the second pixels P2 are arranged in an array, the first connection line 132 can extend along the direction X from the second area B to the first area A. For example, the first connection line 132 is arranged between different columns of second pixels P2 along the direction X from the second area B to the first area A. The first connection line 132 can be prevented from covering the second pixels P2, thereby ensuring the light emitting effect of the second pixels P2. In addition, the first connection line 132 can extend in a straight line, which is conducive to reducing the length of the first connection line 132, and can better keep the impedance voltage drop of the first signal on the line unchanged, thereby ensuring the accuracy of the first signal acquired by the first pixel P1.

[0056] It should be noted that Figure 6 exemplarily shows that the extension direction of the first connection line 132 is perpendicular to the row direction of the second pixel P2 and is a straight line, so as to reduce the length of the first connection line 132 as much as possible, that is, effectively reduce the impedance voltage drop on the first connection line 132. In other embodiments, the extension direction of the first connection line 132 and the row direction of the second pixel P2 may have different angles, which are not limited here. In addition, Figure 6 exemplarily shows that the first connection line 132 is a straight line. In other embodiments, the first connection line 132 can also be set as a curve as needed, which is not limited here.

[0057] Continue to refer Figure 6 Optionally, along the direction X pointing from the second area B to the first area A, each first partition structure 131 is electrically connected to a row of second pixels P2.

[0058] Specifically, when the first connection line 132 extends along the direction X from the second area B to the first area A, the first connection line 132 is arranged between different rows of second pixels P2 along the direction X from the second area B to the first area A. At this time, the first partition structure 131 can be electrically connected to a row of second pixels P2 to avoid short circuit between the first partition structure 131 and the first connection line 132. At the same time, along the direction X from the second area B to the first area A, each first partition structure 131 is electrically connected to a row of second pixels P2, which can reduce the arrangement of power signal lines and is conducive to simplifying the wiring of the display panel. In other embodiments, the first partition structure 131 can be electrically connected to multiple rows of second pixels P2, that is, multiple rows of first isolation openings are provided in one partition structure 131, and the second pixels P2 are located in the first isolation openings.

[0059] In the above technical solution, the first connection line 132 and the first partition structure 131 are made of the same material, so that the first connection line 132 and the first partition structure 131 can be formed in the same process, which is beneficial to simplifying the manufacturing process of the display panel.

[0060] like Figure 7As shown, the display panel also includes a fan-out area C, which is arranged on a side of the second area B away from the first area A; the fan-out area C is provided with a first fan-out line 140 and a second fan-out line 150, and the first fan-out line 140 is electrically connected to the first connecting line 132; the second area B also includes a second signal line 160, and the second fan-out line 150 is electrically connected to the second signal line 160.

[0061] Specifically, the driving circuit layer is provided with multiple conductive layers. In the second area B, the second signal line 160 is provided in at least one conductive layer. The second signal line 160 is electrically connected to the second pixel P2, and is used to provide a corresponding signal to the second pixel P2. Exemplarily, the second signal line 160 may include a data signal line, a power signal line and an initialization signal line, in which case the second signal line 160 may be electrically connected to the second pixel P2, and is used to provide a data signal, a power signal and an initialization signal to the second pixel P2. The second signal line 160 may also include a gate drive signal line, in which case the second signal line 160 may be electrically connected to the second pixel P2 through a gate drive circuit, and is used to provide a gate drive signal to the second pixel P2.

[0062] The display panel may further include a driving unit, the driving unit is located on a side of the fan-out area C away from the second area B, one end of the first fan-out line 140 and the second fan-out line 150 are electrically connected to the driving unit, and the other end of the first fan-out line 140 is electrically connected to the first connection line 132, which is used to provide a corresponding signal to the first signal line 121 through the first fan-out line 140 and the first connection line 132, so that the first pixel P1 emits light according to the corresponding signal. The other end of the second fan-out line 150 is electrically connected to the second signal line 160, which is used to provide the corresponding signal provided by the driving unit to the second signal line 160 through the second fan-out line 150, so that the second pixel P2 emits light according to the corresponding signal.

[0063] Figure 8 The embodiment of the present invention provides Figure 7 The partially enlarged schematic diagram of the display panel shown in FIG. Figure 8 As shown, the second region B includes a first sub-region B1; the first sub-region B1 is adjacent to the fan-out region C; the first partition structure 131 and the first connection line 132 are disposed in the first sub-region B1;

[0064] Specifically, the second area B can be divided into a first sub-area B1 according to the position of the fan-out area C, so that the first sub-area B1 is adjacent to the fan-out area C. At the same time, the first partition structure 131 and the first connecting line 132 are arranged in the first sub-area B1, so that after the first connecting line 132 is electrically connected to the first fan-out line 140, it can pass through the first sub-area B1 and be electrically connected to the first signal line 121. The length of the first connecting line 132 can be reduced as much as possible, and the impedance voltage drop of the corresponding signal on the line can be better maintained unchanged, thereby ensuring the accuracy of the first pixel P1 obtaining the corresponding signal.

[0065] In some embodiments, the second region B is disposed around the first region A, and the first sub-region B1 is located between the first region A and the fan-out region C.

[0066] Continue to refer Figure 7 and Figure 8 The second area B also includes two second sub-areas B2; the two second sub-areas B2 are located on both sides of the first sub-area B1.

[0067] Specifically, the second sub-area B2 is also provided with a second pixel P2, and a second signal line 160 for providing a signal to the second pixel P2. The driving unit provides a corresponding signal to the second signal line 160 in the second sub-area B2 through the second fan-out line 150, and can control the second sub-area B2 to realize display. The two second sub-areas B2 are located on both sides of the first sub-area B1, so that the lengths of the signal lines in the two second sub-areas B2 can be as similar as possible, and the consistency of the impedance voltage drop of the signal lines in the two second sub-areas B2 can be improved, which is conducive to further improving the display uniformity of the second area B. Exemplarily, when the first sub-area B1 has a symmetry axis extending along the column direction X of the second pixel P2, the two second sub-areas B2 can be arranged about the symmetry axis so that the lengths of the signal lines in the two second sub-areas B2 are the same, which is conducive to further improving the display uniformity of the second area B.

[0068] On the basis of the above technical solutions, the first partition structure 131 is also arranged in the second sub-area B2.

[0069] Specifically, when the first partition structure 131 is disposed in the second sub-region B2, it can be electrically connected to the second pixel P2 in the second sub-region B2, and is used to provide a power signal for the second pixel P2 in the second sub-region B2. By disposing the first partition structure 131 in the second sub-region B2, the consistency between the first sub-region B1 and the second sub-region B2 can be improved, which is beneficial to improving the uniformity of the reflection of the second region B, thereby facilitating the reduction of the mura phenomenon in the second region B, and further improving the display uniformity of the display panel.

[0070] Continue to refer Figures 6 to 8The first conductive layer 130 further includes a second connection line 133 disposed on the same layer as the first partition structure (not shown in the figure), and the second connection line 133 is located in the second sub-area B2.

[0071] Specifically, the second connection line 133 can be formed in the same process as the first partition structure 131 and the first connection line 132. By providing the second connection line 133 in the second sub-area B1, the consistency of the first sub-area B1 and the second sub-area B2 can be further improved, which is beneficial to improving the reflection uniformity of the second area B, thereby facilitating reducing the mura phenomenon of the second area B, and further improving the display uniformity of the display panel.

[0072] Optionally, the second connection line 133 is made of the same material as the first connection line 132;

[0073] Specifically, the structure of the second connecting line 133 can be the same as the material of the first connecting line 132, so as to further improve the consistency between the first sub-area B1 and the second sub-area B2, and improve the reflection uniformity of the second area B, which is beneficial to reduce the mura phenomenon of the second area B and further improve the display uniformity of the display panel.

[0074] In a preferred embodiment, the first area A is a circular main screen area, the second area B is an annular secondary screen area, and the extension direction of the first connection line 132 and the second connection line 133 is toward the center of the circular main screen area.

[0075] Optionally, the second region B includes a first power signal line VSS1 , and the first isolation structure 131 is electrically connected to the first power signal line VSS1 .

[0076] Specifically, one end of the first power signal line VSS1 is electrically connected to the driving unit, and the other end is electrically connected to the second pixel P2 of the second area B through the first partition structure 131, and the driving unit provides the first power signal to the second pixel P2 of the second area B through the first power signal line VSS1. Exemplarily, the second pixel P2 includes a cathode, the first partition structure 131 is electrically connected to the cathode, and the first power signal line VSS1 provides the first power signal to the cathode.

[0077] On the basis of the above technical solutions, the first signal line 121 includes a second power signal line VSS2 , and the second power signal line VSS2 is electrically connected to the first power signal line VSS1 through the first connection line 132 .

[0078] Specifically, one end of the second power signal line VSS2 can be electrically connected to the first pixel P1, and the other end of the second power signal line VSS2 can be electrically connected to the first power signal line VSS1 through the first connecting line 132, thereby sharing a power signal, which is conducive to simultaneously controlling the display of the first area A and the second area B.

[0079] On the basis of the above technical solutions, the structures of the second pixels P2 in the first sub-area B1 and the second sub-area B2 are the same.

[0080] Specifically, when the structures of the second pixels P2 of the first sub-area B1 and the second sub-area B2 are the same, it may include that the film layer structures used to form the second pixels P2 in the first sub-area B1 and the second sub-area B2 are the same, and it may also include that the arrangements of the second pixels P2 in the first sub-area B1 and the second sub-area B2 are the same. Exemplarily, it may include that the pixel arrangements of the second pixels P2 of the first sub-area B1 and the second sub-area B2 are the same, and it may also include that the positional relationship and pattern of each film layer of different second pixels P2 are the same. By setting the structures of the second pixels P2 of the first sub-area B1 and the second sub-area B2 to be the same, the consistency between the first sub-area B1 and the second sub-area B2 can be further improved, which is beneficial to improving the uniformity of the reflection of the second area B, thereby facilitating reducing the mura phenomenon of the second area B, and further improving the display uniformity of the display panel.

[0081] Continue to refer Figure 7 and Figure 8 , the first signal line 121 further includes a driving signal line S1 and a data signal line D1; the first connection line 132 includes a first sub-connection line 1321 and a second sub-connection line 1322; the first sub-connection line 1321 is electrically connected to the driving signal line S1, and the second sub-connection line 1322 is electrically connected to the data signal line D1;

[0082] Specifically, the first area A may include a display area and a non-display area, and the first pixel P1 is arranged in the display area. The non-display area is also arranged in the gate drive circuit and is electrically connected to the first pixel P1, and is used to provide a gate drive signal for the first pixel P1. The drive signal line S1 may include an initialization signal line and a gate drive signal line, and the initial signal line may be electrically connected to the first pixel P1, and is used to provide an initialization signal for the first pixel P1. The gate drive signal line may be electrically connected to the gate drive circuit, and is used to provide a gate drive signal to the gate drive circuit, so that the gate drive circuit forms a scan signal according to the gate drive signal, and outputs it to the first pixel P1, and provides a scan signal for the first pixel P1. The data signal line D1 may be electrically connected to the first pixel P1, and is used to provide a data signal for the first pixel P1. The number of the first sub-connection lines 1321 is equal to the number of the drive signal lines S1, and they are electrically connected accordingly, and the number of the second sub-connection lines 1322 is equal to the number of the data signal lines D1, and they are electrically connected accordingly, so that the first signal line 121 can obtain the corresponding signal through the first connection line 132.

[0083] At the same time, the second area B may also include a display area and a non-display area, and the second pixel P2 is arranged in the display area. The non-display area is also arranged in the gate drive circuit and is electrically connected to the second pixel P2, and is used to provide a gate drive signal to the second pixel P2. The second area B also includes a second signal line, which is used to provide a second signal to the second pixel P2. The second signal line and the first signal line may include the same type of signal line. Exemplarily, the second signal line also includes a drive signal line and a data signal line. Among them, the drive signal line may include an initialization signal line and a gate drive signal line. Its specific connection relationship is the same as the connection relationship of the first area A, and will not be repeated here. The second signal line can be electrically connected to the drive unit, so that the drive unit can directly provide the second pixel P2 with a second signal through the second signal line.

[0084] Optionally, the first sub-connection line 1321 is disposed on both sides of the second sub-connection line 1322 .

[0085] Specifically, the non-display area of ​​the first area A can be set on at least one side of the display area, so that the gate driving circuit is set on at least one side of the display area. By setting the first sub-connection line 1321 on both sides of the second sub-connection line 1322, it is helpful to simplify the wiring setting of the corresponding electrical connection between the first sub-connection line 1321 and the driving signal line S1, and the corresponding electrical connection between the second sub-connection line 1322 and the data signal line D1.

[0086] In addition, when the number of data signal lines D1 is relatively large, the number of second sub-connection lines 1322 may be expanded along the direction from the first sub-area B1 to the second sub-area B2 to ensure that the data signal lines D1 are electrically connected to the second sub-connection lines 1322 .

[0087] In some embodiments, the first connection line 132 and the second connection line 133 are located in the display area in the second zone B. Since the first fan-out line 140 is located in the substrate 110 of the display panel, the two can be connected through a via. Similarly, the first connection line 132 and the first signal line of the first zone A are connected to the substrate 110 through a via, thereby facilitating electrical connection.

Fig. 9 and Fig.10 As shown, the display panel further includes a second conductive layer 170 disposed on one side of the substrate 110 and located in the first area A. The second conductive layer 170 includes a second partition structure 171 having a plurality of second isolation openings. The first pixel P1 is located in the second isolation opening.

[0089] Specifically, the second partition structure 171 is located around the first pixel P1 and is electrically connected to the first pixel P1 to provide a power signal to the first pixel P1. Exemplarily, the structure of the second partition structure 171 can be the same as the film structure of the first partition structure 131. The first pixel P1 includes a cathode, and the second partition structure 171 is electrically connected to the cathode of the corresponding first pixel P1 to provide a power signal to the first pixel P1. In addition, the second power signal line VSS2 can be electrically connected to the first pixel P1 through the second partition structure 171 to provide a power signal to the first pixel P1.

[0090] Optionally, the second partition structure 171 is in a grid shape and is electrically connected to all the first pixels P1 .

[0091] Specifically, the second partition structure 171 is in a grid shape. When the second partition structure 171 is electrically connected to the second power signal line VSS2, a parallel branch for transmitting the power signal can be equivalently added, thereby reducing the impedance of the power signal transmitted by the second partition structure 171, which is beneficial to reducing the impedance voltage drop of the power signal, and further improving the display uniformity of the first area A, that is, improving the display uniformity of the display panel.

[0092] Optionally, the second conductive layer 170 is disposed in the same layer as the first conductive layer 130 .

[0093] Specifically, when the second conductive layer 170 is disposed on the same layer as the first conductive layer 130, the second conductive layer 170 and the first conductive layer 130 can be formed in the same process, thereby simplifying the manufacturing process of the display panel. Exemplarily, in the manufacturing process of the display panel, after forming the first pixel P1 and the second pixel P2, a conductive layer is formed on one side of the substrate 110, and the conductive layer is patterned so that the conductive layer forms the second conductive layer 170 in the first area A and forms the first conductive layer 130 in the second area B.
