[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0026] Figure 1 FIG. 1 is a partial schematic diagram of a display panel in the related art. Figure 1 As shown, the display panel includes a display area AA and a first non-display area NA1, and the first non-display area NA1 is the lower frame area of ​​the display panel. A data connection line 01 is arranged in the display area AA, and the data connection line 01 is introduced into the display area AA from the junction of the first non-display area NA1 and the display area AA, and is connected to the data line in the display area AA. The arrangement of the data connection line 01 in the display area AA can reduce the area occupied by the data leads arranged in a fan-out shape in the first non-display area NA1, which is conducive to narrowing the lower frame. A power signal line 02 that crosses horizontally and vertically and is interconnected is also arranged in the display area AA. The power signal line 02 is made by using the metal layer for making the data connection line 01, and the power signal line 02 that forms a mesh routing in the display area AA can reduce the voltage drop of the power signal, and can also improve and enhance the uniformity of the reflectivity in the display area AA. A positive power supply structure 03 and a negative power supply structure 04 are arranged in the first non-display area NA1. For example, the positive power supply structure 03 is used to provide the positive power supply voltage required for display, and the negative power supply structure 04 is used to provide the negative power supply voltage required for display. For example, the power signal line 02 extending in the first direction y in the middle area of ​​the display area AA is connected to the negative power structure 04, and the positive power structure 03 corresponds to the arrangement area of ​​the first line segment 011. The first line segment 011 is a partial line segment on the data connection line 01, and the first line segment 011 extends along the first direction y and is introduced into the display area AA from the junction of the first non-display area NA1 and the display area AA.

[0027] That is to say, in the display area AA, at the position adjacent to the first non-display area NA1, the area where the mesh power signal line 02 is located corresponds to the negative power structure 04, and the area where the first line segment 011 is arranged corresponds to the positive power structure 03. In the scheme of setting the mesh power signal line 02 and the corresponding negative power structure 04, the width of the positive power structure 03 in the first non-display area NA1 in the second direction x is affected by the number of data connection lines 01. The more the number of data connection lines 01, the greater the width of the positive power structure 03 in the second direction x. The longer the length of the second line segment 012 extending along the second direction x in the data connection line 01, the greater the coupling capacitance. In order to prevent the coupling capacitance from being too large, the length of the second line segment 012 is also limited, thereby limiting the number of data connection lines 01. In addition, the data line in the display area AA corresponding to the R corner of the display panel (i.e., the arc-shaped corner of the display area) is usually connected to the data terminal through the data connection line 01, and then there is no need to set the data lead near the R corner, thereby narrowing the frame. The arc angle of the R angle also affects the number of data connection lines 01. The number of data connection lines 01 affects the width of the positive power supply structure 03 in the second direction x. A smaller width of the positive power supply structure 03 in the second direction x will increase the impedance of the positive power supply structure 03, which is not conducive to the brightness uniformity of the display area.

[0028] In order to solve the problems existing in the related art, the need to set a data connection line to reduce the lower frame and reduce the impedance of the first power structure (such as the positive power structure) is considered. An embodiment of the present invention provides a display panel, and the shapes of the first power structure and the second power structure in the first non-display area are designed to increase the area of ​​the first power structure, reduce the impedance of the first power structure, and improve the brightness uniformity of the display area.

[0029] Figure 2 A partial schematic diagram of a display panel provided by an embodiment of the present invention, Figure 3 for Figure 2 A partial enlarged view of the Q1 position in the middle area. Figure 2 As shown, the display panel includes a display area AA and a first non-display area NA1 located on one side of the display area AA along a first direction y, and the first non-display area NA1 includes a first power structure 10 and a second power structure 20. A plurality of light emitting devices ( Figure 2(not shown), the light-emitting device may be an organic light-emitting device or an inorganic light-emitting device. The first power structure 10 is used to provide a positive power supply voltage to the light-emitting device in the display area AA, and the second power structure 20 is used to provide a negative power supply voltage. Taking the light-emitting device as an organic light-emitting device as an example, the light-emitting device includes a stacked anode, a light-emitting layer and a cathode. The anodes of each light-emitting device are isolated from each other, and the cathodes of each light-emitting device are connected to each other to form a common electrode. The anode of the light-emitting device receives the positive power supply voltage through the pixel circuit, and the cathode of the light-emitting device receives the negative power supply voltage.

[0030] Figure 4 It is a structural schematic diagram of the two film layers where the first power structure is located at the position of region Q1. Figures 2 to 4 From the perspective of FIG. 1 , the first power structure 10 includes a first subsection 11 and a second subsection 12. The first subsection 11 and the second subsection 12 are arranged in different layers and are electrically connected. The second subsection 12 includes a first subsection 121 and a second subsection 122 connected to each other. The first subsection 11 is located on the third metal layer M3 on the substrate, and the second subsection 12 is located on the fourth metal layer M4 on the substrate. Figure 3 It can be seen from the schematic top view that the first sub-portion 121 overlaps with the first sub-portion 11 in a direction perpendicular to the plane of the substrate. Figure 2 From the perspective of the embodiment, the second sub-portion 122 is located on the side of the first sub-portion 121 away from the display area AA. The length of the second sub-portion 122 in the second direction x is greater than the length of the first sub-portion 121 in the second direction x, and the second direction x intersects the first direction y. In other words, the second sub-portion 12 protrudes outwardly along the second direction x relative to the first sub-portion 11.

[0031] In the embodiment of the present invention, the first power structure 10 includes a first subsection 11 and a second subsection 12 which are arranged in different layers and are electrically connected. The first subsection 121 in the second subsection 12 overlaps with the first subsection 11. The second subsection 122 in the second subsection 12 is located on a side of the first subsection 121 away from the display area AA, and the length of the second subsection 122 in the second direction x is greater than the length of the first subsection 121 in the second direction x. The shape of the second subsection 12 is designed, and the length of the second subsection 122 in the second subsection 12 in the second direction x is set to be larger, which increases the area of ​​the second subsection 12 in the first power structure 10, can reduce the impedance of the first power structure 10, and improve the brightness uniformity of the display area.

[0032] like Figure 2As shown, the display area AA includes a data connection line 31, a second power signal line 32, and a second auxiliary power line 33; the second power signal line 32 extends along the first direction y, the second auxiliary power line 33 extends along the second direction x, the second power signal line 32 crosses and is electrically connected with the second auxiliary power line 33; one end of the data connection line 31 is electrically connected to a data line (not shown) in the display area AA, and the other end is connected to a data terminal in the non-display area, and the data terminal is connected to a display driver chip, and the data terminal provides a data signal to the data line through the data connection line 31. The data connection line 31 includes at least one first line segment 311 extending along the first direction y and at least one second line segment 312 extending along the second direction x; the first line segment 311 and the second power signal line 32 are located in the same layer, and the second line segment 312 and the second auxiliary power line 33 are located in the same layer.

[0033] The display area AA includes a first area Z1 and a second area Z2 adjacent to the first non-display area NA1, a plurality of first line segments 311 are arranged continuously along the second direction x in the first area Z1, and a plurality of second power signal lines 32 are arranged continuously along the second direction x in the second area Z2. The first line segments 311 in the first area Z1 are introduced into the display area AA from the boundary position of the first non-display area NA1 and the display area AA. In the first direction y, the first power structure 10 at least partially overlaps with the first area Z1, and the second power structure 20 at least partially overlaps with the second area Z2.

[0034] Figure 2 , the first power structure 10 corresponds to the arrangement area of ​​the first line segment 311 in the data connection line 31, and the second power structure 20 corresponds to the arrangement area of ​​the second power signal line 32. Figure 3 The enlarged view in the middle shows that the second power structure 20 at the middle position is connected to the second power signal line 32 in the display area AA along the first connecting line 41.

[0035] The display panel provided by the embodiment of the present invention is provided with a data connection line 31 in the display area AA. The data connection line 31 is used to connect the data lines in the display area AA, which can reduce the occupied area of ​​the data leads (data leads are used to connect the data lines and data terminals) arranged in a fan-out shape in the first non-display area NA1, which is conducive to narrowing the lower frame. The second power signal line 32 and the second auxiliary power line 33 are made by using the film layer made of the data connection line 31, so that the second power signal line 32 and the second auxiliary power line 33 are crossed and electrically connected to form a mesh routing, which can not only reduce the voltage drop of the transmission power signal, but also improve the uniformity of the metal line layout in the plane, ensure that the reflectivity in the display area AA is relatively uniform, and improve the display effect. A second power structure 20 connected to the second power signal line 32 is provided in the first non-display area NA1 to provide a signal to the second power signal line 32.

[0036] like Figures 2 to 4 As shown, the second power structure 20 includes a third subsection 21, the third subsection 21 is in the same layer as the first subsection 11, and the first subsection 11 and the third subsection 21 are arranged along the second direction x; along the first direction y, the third subsection 21 is located on the side of the second subsection 122 close to the display area AA. And the third subsection 21 and the second subsection 122 at least partially overlap in the first direction y. The width of the second subsection 122 in the second subsection 12 of the first power structure 10 in the second direction x is set to be greater than the width of the first subsection 121 in the second direction x, and the third subsection 21 of the second power structure 20 is located on the side of the second subsection 122 close to the display area AA. It is equivalent to enlarging the area of ​​the second subsection 122 so that it overlaps with the third subsection 21 of the second power structure 20 in the first direction y. By changing the shape of the second subsection 12 in the first power structure 10 to increase the area of ​​the second subsection 12, the corresponding relationship between the third subsection 21 in the second power structure 20 and the display area AA may not be changed, and the corresponding connection relationship between the second power structure 20 and the arrangement area of ​​the second power signal line 32 is not affected. The second subsection 122 in the second subsection 12 overlaps with the third subsection 21 in the first direction y, which can increase the area of ​​the second subsection 12 in the first power structure 10, thereby reducing the impedance of the first power structure 10 and improving the brightness uniformity of the display area.

[0037] like Figure 3 and Figure 4 As shown, the second power structure 20 includes a fourth division 22, and the fourth division 22 and the third division 21 are arranged in different layers and electrically connected, and the length of the fourth division 22 in the second direction x is less than the length of the third division 21 in the second direction x. The fourth division 22 and the second division 12 are in the same layer, and the fourth division 22 and the second division 12 are arranged along the second direction x. It can be seen from the top view that the fourth division 22 overlaps with the third division 21 to form an L-shaped structure, and the first division 11 and the second division 12 overlap to form an L-shaped structure. The second division 12 and the third division 21 overlap in the first direction y, so that the first power structure 10 and the second power structure 20 are staggered and stuck to each other, and the area of ​​the second division 12 in the first power structure 10 can be increased without reducing the length occupied by the second power structure 20 in the second direction x. In this way, the impedance of the first power structure 10 can be reduced and the brightness uniformity of the display area can be improved.

[0038] In some embodiments, Figure 5Another structural schematic diagram of the two film layers where the first power structure is located in the embodiment of the present invention. The third subsection 21 includes a third subsection 211 and a fourth subsection 212 that are connected to each other. Along the first direction y, the fourth subsection 212 is located on the side of the third subsection 211 away from the display area AA; the length of the fourth subsection 212 in the second direction x is less than the length of the third subsection 211 in the second direction x. In the direction perpendicular to the plane where the substrate is located, the fourth subsection 212 overlaps and is electrically connected to the fourth subsection 22. Such a setting can increase the area of ​​the third subsection 21, which is beneficial to reducing the impedance of the second power structure 20.

[0039] In one embodiment, if Figure 2 As shown, the display panel includes two first power structures 10, and along the second direction x, the two first power structures 10 are respectively located on both sides of the second power structure 20. The two first power structures 10 refer to two first power structures 10 that are located at different positions and are not directly connected. In fact, the two first power structures 10 are respectively electrically connected to the first power trace 50, and the two first power structures 10 are electrically connected. The display area AA includes a center line X extending along the first direction y, and the extension line of the center line X overlaps with the second power structure 20; the shape of the display area AA is symmetrical about the center line X. The third subsection 21 includes a first end and a second end in the second direction x; Figure 2 The first end and the second end are not marked. The first end and the second end can be understood as the two ends of the third division 21 in the second direction x. Along the first direction y, the first end is located on the side of the second sub-division 122 in one first power structure 10 close to the display area AA, and the second end is located on the side of the second sub-division 122 in another first power structure 10 close to the display area AA. That is, the length of the fourth division 22 in the second power structure 20 in the second direction x is reduced, so that the third division 21 and the fourth division 22 form a T-shaped structure, and the two second sub-divisions 122 in the first power structure 10 on both sides of the second power structure 20 can overlap with the ends of the third division 21 in the first direction y respectively. In this way, the impedance of the first power structure 10 can be reduced to a large extent, and the brightness uniformity of the display area can be improved.

[0040] In addition, if Figure 2 As shown, two edge second power structures 23 are further provided in the first non-display area NA1. The edge second power structures 23 are located at the ends of the first non-display area NA1 in the second direction x. The edge second power structures 23 transmit the same signal as the second power structure 20 at the center.

[0041] In some embodiments, Figure 2As shown, along the second direction x, the length of the fourth sub-portion 22 is less than the length of the second sub-portion 122. Since the fourth sub-portion 22 in the second power structure 20 and the second sub-portion 122 in the first power structure 10 are located in the same film layer, within the limited space of the first non-display area NA1, the length of the fourth sub-portion 22 in the second direction x is reduced, and the length of the second sub-portion 122 can be increased, thereby increasing the area of ​​the second sub-portion 12 in the first power structure 10, thereby reducing the impedance of the first power structure 10.

[0042] Combination Figure 2 and Figure 3 From the perspective of FIG. 1 , the display area AA includes a second power signal line 32 extending along the first direction y, and the first non-display area NA1 includes a plurality of first connection lines 41 extending along the first direction y. One end of the first connection line 41 is connected to the second power structure 20, and the other end is connected to the second power signal line 32. The first connection line 41 and the fourth subsection 22 are located in the same layer. Figure 3 It can be seen that one end of a portion of the first connecting line 41 is connected to the third sub-portion 21 , and one end of a portion of the first connecting line 41 is connected to the fourth sub-portion 22 . Figure 3 The black solid circle in the middle indicates the via connection position between the first connection line 41 and the third division 21. In the embodiment of the present invention, the length of the fourth division 22 in the second power structure 20 in the second direction x is set to be less than the length of the third division 21 in the second direction x. By reducing the length of the fourth division 22 in the second direction x, the area of ​​the second division 12 in the first power structure 10 can be increased in the same film layer of the fourth division 22, and the impedance of the first power structure 10 can be reduced by increasing the area of ​​the second division 12. At the same time, it is ensured that the length of the third division 21 in the second power structure 20 in the second direction x is still long enough, and the first connection line 41 extending along the first direction y can still be used to connect the second power structure 20 and the second power signal line 32 located in the display area AA, so as to ensure the electrical reliability of the second power structure 20.

[0043] Figure 6 for Figure 3 A schematic diagram of a cross section at the midline AA′. Figure 6 The same fill pattern indicates the same film layer. Figure 6 The substrate 00 is shown schematically. Figure 6 It can be seen that the first power supply wiring 50 and the third section 21 of the second power supply structure 20 are located in the same film layer, and the first connecting line 41 and the second section 12 of the first power supply structure 10 are located in the same film layer. Figure 6 It is illustrated that the first connection line 41 is connected to the third section 21 through a via hole penetrating the insulating layer.

[0044] In some embodiments, Figure 2As shown, the first non-display area NA1 includes a first power supply line 50; the first power supply line 50 is located on the side of the first power supply structure 10 and the second power supply structure 20 close to the display area AA, and the first power supply structure 10 is electrically connected to the first power supply line 50. The first power supply line 50 is wired around the lower edge of the display area AA. Specifically, the first power supply line 50 and the first subsection 11 in the first power supply structure 10 are located in the same layer, and the two are in contact and connected.

[0045] The display panel includes a plurality of second connection lines 42, combined with Figure 3 From the perspective of FIG. 1 , the second connecting line 42 extends along the first direction y. Figure 3 It can be seen from the top view that, along the direction perpendicular to the plane of the substrate, at least one second connection line 42 at least partially overlaps with the third subsection 21; one end of the second connection line 42 is connected to the second subsection 12, and the other end is connected to the first power line 50. Specifically, one end of the second connection line 42 is connected to the second subsection 122 in the second subsection 12.

[0046] Figure 7 for Figure 3 A schematic diagram of a cross section at the midline BB′. Figure 7 The same fill pattern indicates the same film layer. Figure 7 The substrate 00 is shown schematically. Figure 7 It can be seen that the second connecting line 42 is connected to the first power supply line 50 through a via penetrating the insulating layer, and the second connecting line 42 and the second division 12 in the first power supply structure 10 are located in the same film layer. The third division 21 in the second power supply structure 20 and the first power supply line 50 are located in the same layer. That is, the first power supply line 50, the first division 11 in the first power supply structure 10, and the third division 21 in the second power supply structure 20 are located in the same layer, the second division 12 in the first power supply structure 10, and the fourth division 22 in the second power supply structure 20 are located in the same layer, and the first power supply structure 10 and the second power supply structure 20 respectively include divisions located in two metal layers, so that the impedance of the two power supply structures is relatively low, which is conducive to reducing the voltage drop of the power supply signal and improving the display uniformity.

[0047] In the embodiment of the present invention, a second connection line 42 extending along the first direction y is provided, and the second connection line 42 is connected between the first power supply line 50 and the second sub-section 122 of the second sub-section 12. The first power supply line 50 and the first power supply structure 10 are connected by the second connection line 42, and a grid structure is formed in the first non-display area NA1, so that the voltage drop of the power supply voltage transmitted by the first power supply structure 10 can be further reduced, which is conducive to improving the display uniformity. In addition, the overlap area between the second connection line 42 and the third sub-section 21 is small, so that there is no large overlap between the structure transmitting the positive power supply voltage and the structure transmitting the negative power supply voltage, and the display panel has better reliability.

[0048] like Figure 4 As shown, the first connection line 41, the second connection line 42, the second subsection 12 in the first power structure 10, and the fourth subsection 22 in the second power structure 20 are located in the same film layer.

[0049] In some embodiments, Figure 6 and Figure 7 As shown, the first non-display area NA1 includes a first retaining wall 61 and a second retaining wall 62; along a direction e perpendicular to the plane where the substrate is located, the second sub-portion 122 and the first retaining wall 61 at least partially overlap. Figure 3 From the perspective of the embodiment of the present invention, the first retaining wall 61 is located on the side of the second retaining wall 62 away from the display area. The first retaining wall 61 and the second retaining wall 62 are used as encapsulation boundaries of the encapsulation layer. The encapsulation layer is used to encapsulate and protect the light-emitting device, wherein the encapsulation layer includes at least one inorganic encapsulation layer and at least one organic encapsulation layer. The second sub-portion 122 and the first retaining wall 61 are arranged to at least partially overlap, that is, the second sub-portion 122 is extended in the first direction y to the area where the first retaining wall 61 is located, thereby enabling the second sub-portion 122 to have a larger width in the first direction y, which is beneficial to reducing the impedance of the first power structure 10 and improving display uniformity.

[0050] In some embodiments, in combination Figure 3 and Figure 6 From the perspective of FIG. 1 , along the direction e perpendicular to the plane where the substrate is located, the first retaining wall 61 overlaps with the edge of the second sub-section 122 on the side away from the display area AA in the first direction y. In other words, the edge of the second sub-section 122 on the side away from the display area AA in the first direction y is covered by the first retaining wall 61. This can prevent the edge of the second sub-section 122 from being exposed to the outside and corroded, thereby ensuring the performance reliability of the first power supply structure 10.

[0051] like Figure 3 As shown, along the first direction y, the minimum distance between the second sub-section 122 and the third sub-section 21 is d, d ≥ 3 μm. In the embodiment of the present invention, the second sub-section 122 and the third sub-section 21 are arranged in different layers, so that the distance between them in the first direction y can be small. Figure 6 From the perspective of the embodiment, when the distance between the second sub-section 122 and the third sub-section 21 is small, the edges of the second sub-section 122 and the third sub-section 21 can be covered by the organic layer at the same time, ensuring that the edges of the third sub-section 21 will not be side-etched in the subsequent etching process. When d≥3μm, the coupling capacitance between the second sub-section 122 and the third sub-section 21 can be small, and the coupling capacitance between the first power structure 10 and the second power structure 20 is small, and the reliability of the power supply voltage transmitted by the two is higher.

[0052] In some embodiments, in combination Figure 2 and Figure 3From the perspective of the first non-display area NA1, the first sub-area Z3 is located in the second sub-portion 122 of the second sub-portion 12 along the first direction y. Figure 4 to understand its position) and the display area AA, along the second direction x, the first sub-area Z3 is located in the first sub-portion 121 (combined with Figure 4 In the first sub-area Z3, n first connecting lines 41 form a connecting line group ( Figure 3 (not marked in the figure), the second connecting lines 42 and the connecting line groups are alternately arranged along the second direction x. Figure 3 Take n=1 as an example, that is, in the first sub-zone Z3, the first connection lines 41 and the second connection lines 42 are alternately arranged in the second direction x.

[0053] Combination Figure 2 From the perspective of FIG. 1 , the first connecting line 41 connects the second power structure 20 and the second power signal line 32 located in the display area AA, and the pixel circuits arranged along the first direction y in the display area AA form a pixel circuit column. Two adjacent second power signal lines 32 may overlap with two adjacent pixel circuit columns, or one pixel circuit column may be spaced between two adjacent second power signal lines 32. In other words, a second power signal line 32 may be correspondingly arranged at the position where a pixel circuit column is arranged, or a second power signal line 32 may be correspondingly arranged at the position where two pixel circuit columns are arranged.

[0054] For example, in a solution where a second power signal line 32 is set corresponding to a pixel circuit column, when the first connection line 41 is set to be connected to the second power signal line 32 in the display area AA, there is a certain space between adjacent first connection lines 41. Figure 3 The second connecting line 42 is arranged on the same layer as the first connecting line 41, and the second connecting line 42 is arranged between adjacent first connecting lines 41. This can not only make full use of the film layer where the first connecting line 41 is located, but also use the second connecting line 42 to connect the first power line 50 and the first power structure 10 in the first non-display area NA1 to form a grid structure, which can further reduce the voltage drop of the power voltage transmitted by the first power structure 10.

That is, two first connection lines 41 are spaced between two adjacent second connection lines 42. The first line segment 311, the first power signal line 35, and the second power signal line 32 in the data connection line 31 are schematically shown in the display area AA. The first power signal line 35 is connected to the first power line 50, and the second power signal line 32 is connected to the second power structure 20 through the first connection line 41.

The second power signal line 32 is arranged according to the arrangement method of the first line segment 311 in the data connection line 31, which can improve the uniformity of the metal wiring in the display area AA, so that the reflectivity in the display area is uniform.

Optionally, the segment of the first data line 361 located in the display area AA and the first sub-segment 3611 located in the first non-display area NA1 are located in the same layer.

[0059] Combination Fig.10 From the second zone Z2 in the display area AA shown in the figure, the second zone Z2 at least partially overlaps with the second power structure 20 along the first direction y, and a second power signal line 32 is arranged in the second zone Z2. In the second zone Z2, a plurality of second power signal lines 32 are continuously arranged along the second direction x; the second power signal line 32 is connected to the second power structure 20 through a first connecting line 41. A first power signal line 35 is also arranged in the second zone Z2, and the first power signal line 35 is connected to the first power structure 10 through a second connecting line 42. Fig.10 It can be seen from the top view that along the direction perpendicular to the plane where the substrate is located, the first sub-segment 3611, the first connection line 41, and the second connection line 42 overlap with the first power supply line 50 respectively. In the first sub-area Z3, along the second direction x, the first sub-segment 3611 is adjacent to the second connection line 42 and / or the first connection line 41.

[0060] Fig.11 for Fig.10 A cross-sectional schematic diagram is shown at the position of the midline CC'. Fig.11It can be seen that along the direction e perpendicular to the plane where the substrate 00 is located, the first sub-segment 3611, the first connecting line 41, and the second connecting line 42 overlap with the first power supply line 50 respectively. The display panel includes a first metal layer M1, a second metal layer M2, a third metal layer M3, and a fourth metal layer M4 located on the substrate 00.

Among them, the first sub-data lead 71a and the second sub-data lead 71b are alternately electrically connected to the first sub-line segment 3611. Such a setting can reduce the spacing between two adjacent first data leads 71, thereby reducing the occupied area of ​​multiple data leads arranged in a fan-out shape, which is conducive to the narrowing of the lower frame of the display panel.

[0062] In the embodiment of the present invention, the third division 21 of the second power structure 20 and the first power trace 50 are located in the same layer, that is, the third division 21 and the first power trace 50 are located in the third metal layer M3. Among them, the data line 36 is located in the fourth metal layer M4. Optionally, the second power signal line 32 and the first line segment 311 in the data connection line 31 are located in the fourth metal layer M4. The data line 36, the first line segment 311 in the data connection line 31, and the second power signal line 32 having the same extension direction are made in the same layer, which can reduce the number of metal layers of the display panel, simplify the manufacturing process, and reduce the manufacturing cost.

[0063] In some embodiments, Fig.13 for Fig.10Schematic diagram of the third division. Fig.10 and Fig.13 From the perspective of the third subdivision 21, the first side 21a, the second side 21b and the third side 21c are arranged along the first direction y, and the first side 21a is located on the side of the second side 21b close to the display area AA. The third side 21c is connected to the second side 21b and is located between the first side 21a and the second subdivision 122 along the first direction y. The first side 21a and the second side 21b extend along the second direction x, and the angle formed by the first side 21a and the third side 21c is an acute angle. Such an arrangement can increase the spacing distance between the third subdivision 21 and the first subdivision 11 arranged on the same layer, and ensure that the electrical performance of the first power supply structure 10 and the second power supply structure 20 is reliable.

[0064] like Fig. 9 As shown, the data connection line 31 includes a first line segment 311 extending along a first direction y and a second line segment 312 extending along a second direction x. The data connection line 31 is electrically connected to the second data line 362 .

In addition, one end of the data connection line 31 is connected to the second data line 362, and the other end is connected to the second data lead 72. In other words, part of the second data lead 72 is electrically connected to the third data line 363, and part of the second data lead 72 is connected to the second data line 362 through the data connection line 31. The first data line 361 and the third data line 363 are directly connected to the data lead 70 respectively, and the difference is that the first data line 361 and the third data line 363 are located at different positions in the display area AA.

[0066] Combination Fig.10 and Fig.11From the perspective of FIG. 1 , the second data lead 72 includes a third sub-data lead 72a located in the first metal layer M1 and a fourth sub-data lead 72b located in the second metal layer M2; the third sub-data lead 72a and the fourth sub-data lead 72b overlap at least partially with the first sub-portion 11 in the first power structure 10, respectively. The third sub-data lead 72a and the fourth sub-data lead 72b are arranged alternately. Such an arrangement can reduce the spacing between two adjacent second data leads 72, thereby reducing the occupied area of ​​multiple data leads arranged in a fan-out shape, and further helps to narrow the lower frame of the display panel.

[0067] In some embodiments, Fig.11 As shown, the first power structure 10 includes a first subdivision 11 and a second subdivision 12 arranged in different layers. At least part of the first subdivision 11 and at least part of the second subdivision 12 are electrically connected through a plurality of vias V, and / or at least part of the first subdivision 11 and at least part of the second subdivision 12 are connected in planar contact. Fig.10 From the perspective of FIG. 1 , in the partial area of ​​the first power structure 10 close to the display area AA along the first direction y, the first sub-portion 11 and the second sub-portion 12 overlap and pass through the via hole V( Fig.10 In the first power structure 10, the first subdivision 11 and the second subdivision 12 are connected in a planar contact manner in a partial area away from the display area AA along the first direction y. The planar contact connection can increase the contact area between the first subdivision 11 and the second subdivision 12, which is beneficial to reducing the overall impedance of the first power structure 10. At the position where the first subdivision 11 and the second subdivision 12 are connected through the via V, a hollow K is also provided on the second subdivision 12. The provision of the hollow K can help to discharge gas in the process and prevent film peeling.

[0068] In some embodiments, Fig.14 A partial schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.14As shown, the first non-display area NA1 also includes a bending area Q2 and a pad area Q3; the inorganic layer on the substrate in the bending area Q2 is removed so that the bending area Q2 can be bent, and a plurality of pads 83 are provided in the pad area Q3. Along the first direction y, the pad area Q3 is located on the side of the bending area Q2 away from the display area AA. The first non-display area NA1 includes two first power structures 10, a second power structure 20 located at the center position, and two edge second power structures 23 located at the edge positions. The two first power structures 10 are electrically connected to the first power traces 50, respectively. Since the second power structure 20 is separated between the two first power structures 10, they cannot be contacted and connected. The second power structure 20 and the two edge second power structures 23 transmit the same signal, and the edge second power structure 23 is electrically connected to the second power signal line 32 in the display area AA overlapping with it in the first direction y. The first non-display area NA1 includes a first crossover 81 and a second crossover 82, wherein the first crossover 81 is connected to the first power structure 10 and extends to the pad area Q3 via the bending area Q2; the second power structure 20 and the edge second power structure 23 are respectively connected to the second crossover 82, and the second crossover 82 extends to the pad area Q3 via the bending area Q2. A first power structure 10 is connected to at least three first crossovers 81. A second power structure 20 / edge second power structure 23 is respectively connected to a second crossover 82. Optionally, the first crossover 81, the second crossover 82 and the second subsection 12 in the first power structure 10 are located in the same film layer.

[0069] In the embodiment of the present invention, the second subsection 12 in the first power structure 10 includes a first subsection 121 and a second subsection 122. The second subsection 122 is located on the side of the first subsection 121 away from the display area AA along the first direction y, and the length of the second subsection 122 in the second direction x is greater than the length of the first subsection 121 in the second direction x. Thus, the area of ​​the second subsection 12 is increased, which is conducive to reducing the impedance of the first power structure 10. At the same time, the length of the second subsection 122 in the second direction x is relatively large, so that the second subsection 122 can be adapted to be provided with three or more first cross-wires 81, which can further reduce the impedance, reduce the voltage drop of the power supply voltage transmitted by the first power structure 10, and improve the display uniformity.

[0070] In some embodiments, the width of the first jump line 81 and the second jump line 82 in the second direction x is relatively large, and exhaust holes can be set on the first jump line 81 and / or the second jump line 82 to discharge the gas generated in the process and prevent film peeling from occurring in a large area of ​​the first jump line 81 and / or the second jump line 82.
