Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] Compared to traditional liquid crystal display (LCD) screens, organic light emitting diode (OLED) display technology has been increasingly used in various electronic devices due to its advantages such as self-luminescence, wide viewing angle, high contrast, low power consumption, and fast response speed. However, with the rapid development of high-resolution and high-quality display products, many technical problems have arisen. People have put forward higher requirements for the power consumption, color deviation, brightness, stability and other performance of OLED display products. Summary of the Invention

[0003] In view of this, the present invention provides a display panel and a display device.

[0004] The present invention discloses a display panel, comprising: a display area, the display area comprising a plurality of first signal lines, at least one first signal line being connected to a first connecting line; the first connecting line comprising a first conductive wire and a second conductive wire being connected to each other, the second conductive wire being arranged in a different layer from the first conductive wire; one end of the first conductive wire being connected to the first signal line, the other end of the first conductive wire being connected to the second conductive wire, the first conductive wire and the first signal line being arranged in a different layer; at least part of the first conductive wire comprising at least one first portion extending along a first direction and at least one second portion extending along a second direction, the first portion and the second portion being arranged in the same layer; wherein the first direction intersects with the second direction.

[0005] Based on the same inventive concept, the present invention also discloses a display device, which includes the above-mentioned display panel.

[0006] Compared with related technologies, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0007] In the display panel provided by this embodiment, at least one first signal line in the display area is connected to the first connecting line, and the first connecting line is provided to include a first conductive wire and a second conductive wire that are connected to each other. The second conductive wire and the first conductive wire are provided in different layers, that is, a first connecting line itself can be provided in two different film layer structures, which can avoid as much as possible the setting of the first connecting line from affecting the film layer wiring structure originally existing in the display area. The first conductive wire and the first signal line are provided in different layers, and need to be connected through a first via at the connection between the first conductive wire and the first signal line. The other end of the first conductive wire is connected to the second conductive wire, and the second conductive wire and the first conductive wire are located in different film layers, and also need to be connected through a second via at the connection between the first conductive wire and the second conductive wire, that is, for the same first connecting wire, at least two wire-changing holes are required to realize the connection between the first connecting wire and the first signal line to complete the transmission of the driving signal. In this embodiment, the first conductive line is arranged so that the entire line can be located in the same film layer, but the first conductive line located in the same film layer can include at least one first portion and at least one second portion extending in different directions. By setting the first conductive line to include both the first portion extending in the first direction and the second portion extending in the second direction, the winding of the first conductive line can be made more flexible, so that the positions of the first via and the second via at the different-layer connection can be adjusted by the first conductive line extending in different directions, and thus the position of the line-changing hole in the display area can be avoided as much as possible from the opening area of ​​the sub-pixel, so that the subsequent light-emitting functional layer in the sub-pixel opening area above the first signal line and the first connecting line can be as flat as possible, or when the opening area of ​​the sub-pixel cannot be avoided, the number of corresponding line-changing holes within the opening area of ​​a sub-pixel can be reduced as much as possible, so as to improve the color deviation problem of the display panel, enhance the display quality, and improve the user experience by optimizing the winding layout of the first connecting line connected to the first signal line.

[0008] Of course, any product implementing the present invention does not necessarily need to achieve all of the above-mentioned technical effects at the same time.

Therefore, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents.

[0033] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Figure 2 yes Figure 1 A schematic diagram of a partially enlarged structure of the M1 region in FIG. 1 (It can be understood that in order to clearly illustrate the structure of this embodiment, Figure 2 The display panel 000 of this embodiment includes:

[0035] Display area AA, display area AA includes a plurality of first signal lines 10, at least one first signal line 10 is connected to the first connection line 20;

[0036] The first connecting line 20 includes a first conductive line 20A and a second conductive line 20B connected to each other, and the second conductive line 20B and the first conductive line 20A are arranged in different layers; one end of the first conductive line 20A is connected to the first signal line 10, and the other end of the first conductive line 20A is connected to the second conductive line 20B, and the first conductive line 20A and the first signal line 10 are arranged in different layers;

[0037] At least part of the first conductive line 20A includes at least one first portion 20A1 extending along a first direction Y and at least one second portion 20A2 extending along a second direction X. The first portion 20A1 and the second portion 20A2 are disposed in the same layer. The first direction Y intersects the second direction X.

[0038] Specifically, the display panel 000 provided in this embodiment can be an organic light emitting diode display panel, and the display panel 000 includes a display area AA. The optional display area AA can include multiple sub-pixels (not shown in the figure), and the sub-pixels can be provided with organic light emitting diodes. The display area AA of this embodiment includes multiple first signal lines 10. It can be understood that the first signal line 10 in this embodiment can be any one or more of the drive signal lines such as scan lines, data lines, power lines, etc. that drive the sub-pixels to emit light. In some other optional embodiments, the display panel 000 of this embodiment can also be a liquid crystal display panel, a micro LED (micro light emitting diode) or a mini LED (sub-millimeter light emitting diode) display panel. The sub-pixels of the display area AA can include light-emitting devices such as micro LED or mini LED. This embodiment does not limit the type of the display panel 000. The structure of the display area AA can be set according to the type of the display panel 000. The design structure of the sub-pixels of the specific display area AA can be understood by referring to the structure of the display panel in the relevant technology.

[0039] In the display panel 000 provided in this embodiment, at least one first signal line 10 of the display area AA is connected to the first connecting line 20. Optionally, the first connecting line 20 may also be located in the display area AA. The first connecting line 20 may be used to connect the first signal line 10 of the display area AA with other signal input terminals in the display panel 000 (such as conductive pads in the non-display area of ​​the display panel 000, not shown in the figure), and is used to transmit the driving signal from the signal input terminal to the first signal line 10 of the display area AA through the first connecting line 20, thereby realizing the display function of the display panel 000.

[0040] In related technologies, if the display panel is an organic light-emitting diode display panel, the color deviation problem caused by the step difference of the film layer below the light-emitting device in the display panel is still a common problem currently faced. Since the pixel driving circuit layer is located below the OLED light-emitting device, the driving circuit layer generally includes more signal wiring, driving devices, etc., and as the resolution of the display screen increases, the number of signal wiring increases further, and the number of wiring holes that need to be set for wiring in different film layers also increases accordingly. The height difference caused by the wiring at the wiring hole position makes the subsequently prepared OLED light-emitting layer uneven, that is, the flatness of the driving circuit layer will directly affect the flatness of the OLED light-emitting device, especially the flatness of the light-emitting functional layer in the OLED, which ultimately leads to color deviation problems on the display screen, affecting the user experience.

[0041] As the resolution of the display panel 000 increases, the number of sub-pixels included in the display panel 000 also increases. In order to improve the space utilization of the display area AA of the display panel 000 and ensure the transmittance of the display area AA, the first signal lines 10 and the first connecting lines 20 located in the display area AA need to be designed with certain windings to avoid affecting the display quality. Optionally, in this embodiment, some of the first connecting lines 20 can be arranged in different layers from the first signal lines 10 ( Figure 2 The arrangement of the first signal line 10 is performed as shown in FIG. 1 , and the arrangement of the first signal line 10 is performed as shown in FIG. 1 , and the arrangement of the first signal line 10 is performed as shown in FIG. 1 .

[0042] It is understandable that when part of the first connecting line 20 can be set in a different layer from the first signal line 10, or when the first signal line 10 and the first connecting line 20 need to adopt a certain winding design in the display area AA, there is a height difference problem of the film layer at the line change hole when the two are in different layers and the line change hole of the first connecting line 20 itself, which makes the subsequent light-emitting functional layer above the first signal line 10 and the first connecting line 20 uneven. If the line change hole happens to be unevenly set at a certain sub-pixel opening position, it can easily cause color deviation problems in the display panel 000, affecting the user experience.

[0043] In order to solve the above problem, the first connecting line 20 of the present embodiment includes a first conductive line 20A and a second conductive line 20B connected to each other, and the second conductive line 20B and the first conductive line 20A are arranged in different layers ( Figure 2(illustrated by different filling patterns in the figure), that is, a first connecting line 20 itself can be set in two different film layer structures, which can avoid as much as possible that the setting of the first connecting line 20 affects the original film layer wiring structure of the display area AA. One end of the first wire 20A of the first connecting line 20 is connected to the first signal line 10. The first wire 20A and the first signal line 10 are set in different layers, that is, the first signal line 10 and the first wire 20A of the first connecting line 20 are located in different film layers, and need to be connected through a first via K1 at the connection between the first wire 20A and the first signal line 10. The other end of the first wire 20A is connected to the second wire 20B. Since the second wire 20B and the first wire 20A are located in different film layers, they also need to be connected through a second via K2 at the connection between the first wire 20A and the second wire 20B. That is, for the same first connecting line 20, at least two wire-changing holes are required to realize the connection between the first connecting line 20 and the first signal line 10 to complete the transmission of the driving signal.

[0044] In this embodiment, at least a portion of the first conductive line 20A of the first connecting line 20 includes at least one first portion 20A1 extending along a first direction Y and at least one second portion 20A2 extending along a second direction X, wherein the first direction Y intersects the second direction X. Optionally, in this embodiment, the first direction Y and the second direction X are perpendicular to each other in a direction parallel to the plane where the display panel 000 is located. In this embodiment, the first portion 20A1 and the second portion 20A2 of the first conductive line 20A are arranged in the same layer, that is, the first conductive line 20A as a whole can be located in the same film layer, but the first conductive line 20A located in the same film layer can include at least one first portion 20A1 and at least one second portion 20A2 extending in different directions. By configuring the first conductive line 20A to include both the first portion 20A1 extending in the first direction Y and the second portion 20A2 extending in the second direction X, the winding of the first conductive line 20A can be made more flexible, so that the positions of the first via K1 and the second via K2 at the different-layer connection can be adjusted by the first conductive line 20A extending in different directions, and thus the position of the line-changing hole in the display area AA can be avoided as much as possible from the opening area of ​​the sub-pixel (such as Figure 2 The area PX indicated by the dotted line in the middle) is used to make the light-emitting functional layer of the sub-pixel opening area above the first signal line 10 and the first connecting line 20 as flat as possible, or the positions of the first via K1 and the second via K2 at the different layer connection can be adjusted by extending the first wire 20A in different directions, so that the sub-pixel opening area (such as Figure 2When the area PX indicated by the dotted line is displayed, the number of corresponding line-changing holes within the opening area of ​​a sub-pixel can be reduced as much as possible, or the positions of the first via hole K1 and the second via hole K2 in the display area AA can be arranged as evenly as possible in the opening area of ​​the sub-pixel, so as to improve the color deviation problem of the display panel 000, enhance the display quality, and improve the user experience by optimizing the winding layout of the first connecting line 20 connected to the first signal line 10.

[0045] Optional, such as Figure 2 and Figure 3 As shown, Figure 3 Schematic diagram of the connection structure of the first signal line and the first connection line in the sub-pixel opening area in the related art (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 3 (The display panel is filled with transparency.) In this embodiment, the display panel is an organic light-emitting diode display panel. The sub-pixel opening area can be understood as at least the area where the sub-pixel's anode structure is located. The organic light-emitting functional layer is formed by vapor deposition above the anode structure. It is understood that this embodiment does not elaborate on the structure of the display panel. For a specific understanding of the anode structure illustrated in this embodiment, reference can be made to the structure of organic light-emitting diode display panels in related art. Therefore, the flatness of the anode structure corresponding to each sub-pixel directly affects the flatness of the evaporated organic light-emitting functional layer, and the flatness of the anode structure corresponding to the sub-pixel is in turn affected by the multiple film layers where the signal lines are located.

[0046] like Figure 3 As shown, taking the first signal line 10' as a data line as an example, in the related art, the anode structure 30' (including the opening area PX' of the sub-pixel) includes at least three line-changing holes below, wherein the first line-changing hole K1' can be understood as a connection hole for the first signal line 10' of the data line to connect to the pixel circuit ( Figure 3 The block diagram 00' represents a partial structure of the pixel circuit. The pixel circuit represented by the block diagram 00' needs to be connected to the first signal line 10' through the first line-changing hole K1' to realize signal transmission. The second line-changing hole K2' can be understood as the first signal line 10' of the data line starting to connect along Figure 3 The connecting hole of the first connecting line 20' extending in the second direction X', the third line-changing hole K3' can be understood as a connecting hole extending along the second direction X'. Figure 3 A portion of the first connecting line 20' extending in the second direction X' begins to connect along Figure 3 The connecting hole of the first connecting line 20' extending in the first direction Y' is Figure 3 A portion of the first connecting line 20' extending in the second direction X' and along Figure 3 A portion of the first connecting line 20' extending in the first direction Y' is provided in a different layer. Figure 3It can be seen that since the partial section of the first connecting line 20' located on the same layer only includes a structure extending in one direction, three line change holes (the first line change hole K1', the second line change hole K2', and the third line change hole K3') are created, which are unevenly distributed below the anode structure 30', causing color deviation problems.

[0047] The embodiment provides Figure 2 In the structure, taking the first signal line 10 as a data line as an example, the first conductor 20A located in the same film layer of the first connecting line 20 in this embodiment includes at least one first portion 20A1 and at least one second portion 20A2 extending in different directions. Optionally, the first conductor 20A includes a first portion 20A1 and a second portion 20A2 connected to each other. One end of the first portion 20A1 is electrically connected to the first signal line 10 through a first via K1, and one end of the second portion 20A2 is electrically connected to the second conductor through a second via K2. Since the first portion 20A1 extends along the first direction Y, it can be extended to the original Figure 3 At the position of the first line-changing hole K1' in the embodiment, the first via K1 of the embodiment can be set Figure 3 In the illustrated related art, at the position of the first line-changing hole K1' where the first signal line 10 is connected to the pixel circuit, by setting the first conductor 20A to include both a first portion 20A1 extending along the first direction Y and a second portion 20A2 extending along the second direction X, the winding of the first conductor 20A is made more flexible, and at least two line-changing holes can be included under the anode structure 30, wherein the position of the first via hole K1 can be understood as the position of the connection hole where the first signal line 10 of the data line is connected to the pixel circuit, and can be understood as the position of the connection hole between the first signal line 10 and the first conductor 20A of the first connection line 20, and can also be understood as the line-changing hole where the pixel circuit represented by the block diagram 00 is connected to the first signal line 10 at least partially overlaps with the first via hole K1, and the position of the second via hole K2 can be understood as the position of the connection hole where the first conductor 20A of the first connection line 20 of the data line starts to connect to the second conductor 20B of the first connection line 20. The first conductor 20A passes through the first portion 20A1 extending along the first direction Y and the second portion 20A2 extending along the second direction X, eliminating the connection hole originally located in the related art. Figure 3 The line-changing hole at the position of the second line-changing hole K2' is moved to the position of the first line-changing hole K1' where the first signal line 10 is connected to the pixel circuit in the related art, so that there are only two line-changing holes under one anode structure 30, and they are evenly arranged under the anode structure 30, thereby improving the problem of display color deviation.

[0048] In some optional implementations, please refer to Figure 4 , Figure 4This is another planar structural schematic diagram of the display panel provided in an embodiment of the present invention. In this embodiment, the display panel 000 also includes a binding area BA, the binding area BA includes a plurality of first conductive pads 401, and the first signal line 10 is electrically connected to the first conductive pad 401 through at least one first connecting line 20.

[0049] This embodiment explains that the non-display area of ​​the display panel 000 also includes a binding area BA, which can be used to set a plurality of conductive pads, which can be used to subsequently bind and electrically connect with a driver chip or a flexible circuit board to provide a display driving signal for the display panel 000 through the driver chip or the flexible circuit board. Optionally, the binding area BA includes a plurality of first conductive pads 401, such as Figure 4 As shown, along the first direction Y, the binding area BA is located on one side of the display area AA. A fan-out area FA is located between the binding area BA and the display area AA. Optionally, the fan-out area FA can be used to provide a first fan-out lead 501 that electrically connects the first signal line 10 of the display area AA to the first conductive pad 401 of the binding area BA. In the display panel 000 of this embodiment, along the second direction X, the display area AA includes a first display area AA1 and second display areas AA2 located on opposite sides of the first display area AA1. The second display area AA2 can be understood as the display areas located on both sides of the edge of the display panel 000 in the second direction X, and the first display area AA1 can be understood as the area closer to the center of the display area AA in the second direction X. A plurality of first signal lines 10 extending along the first direction Y in the display panel 000 are arranged in the second display area AA2. The first signal lines 10 are electrically connected to the first conductive pad 401 in the binding area BA through at least one first connecting line 20 and a first fan-out lead 501, thereby realizing signal transmission between the first signal line 10 and the first conductive pad 401. The first connecting line 20 is located in the display area AA, and the first fan-out lead 501 is located in the fan-out area FA.

[0050] In this embodiment, when the first signal line 10 in the second display area AA2 located near the two side edges of the display panel 000 in the second direction X is electrically connected to the first conductive pads 401 located on the two opposite sides of the binding area BA in the second direction X, the electrical connection between the two is achieved through the first connecting line 20 and the first fan-out lead 501, and the first fan-out lead 501 is set in the fan-out area FA, and the first connecting line 20 is located in the display area AA. By setting the first connecting line 20 within the range of the display area AA, it can be avoided that the first connecting line 20 occupies the space of the fan-out area FA. Figure 4As shown, the first connecting line 20 can gradually extend in the direction close to the first display area AA1 within the display area AA, and then after being connected to the first fan-out lead 501 of the fan-out area FA, the first fan-out lead 501 can be made as far away from the second display area AA2 as possible in the second direction X, which is beneficial to reducing the width W1 of the fan-out area FA in the second direction X, and further reducing the lower frame of the display panel 000.

[0051] It can be understood that the design structure of the present embodiment in which the first connecting line 20 electrically connecting the first signal line 10 of the display area AA and the first conductive pad 401 of the binding area BA is arranged in the display area AA can meet the high-resolution requirement of the display panel 000. Even if the number of the first signal lines 10 is greater, the first connecting line 20 does not need to occupy the space of the fan-out area FA, and therefore the width W1 of the fan-out area FA in the second direction X can still be further compressed, which can meet the high-resolution requirement while ensuring the display performance and achieving a narrower frame.

[0052] It should be noted that the film layer where the first connecting line 20 is located in this embodiment can be provided with a conductive film layer in the display panel 000, so as to avoid the first connecting line 20 affecting the film layer structure of the display panel 000 itself. Optionally, when the display panel 000 is an organic light-emitting diode display panel, the film layer where the first connecting line 20 is located can be provided between the film layer where the anode structure is located and the film layer where the driving transistor is located, or can also be provided in other conductive film layers below the anode structure. This embodiment does not limit this, and during specific implementation, it can be designed according to actual needs.

[0053] In some optional implementations, please continue to refer to Figure 1 and Figure 2 In this embodiment, in the thickness direction of the display panel 000 , at least a portion of the first portion 20A1 overlaps with the first signal line 10 .

[0054] This embodiment explains that when the first signal line 10 is extended along the first direction Y, since one end of the first portion 20A1 of the first conductive wire 20A is connected to the first signal line 10, the first conductive wire 20A and the first signal line 10 are arranged in different layers, the first portion 20A1 of the first conductive wire 20A extends along the first direction Y, and the second portion 20A2 of the first conductive wire 20A extends along the second direction X, that is, the first portion 20A1 located in different film layers and the first signal line 10 have the same extension direction and can be arranged in the thickness direction of the display panel 000. At least a portion of the first portion 20A1 overlaps with the first signal line 10, thereby reducing the space occupied by the first conductive wire 20A of the first connecting line 20 in the display area AA.

[0055] In some optional implementations, please refer to Figure 1 and Figure 5 , Figure 5 yes Figure 1 Another partially enlarged structural diagram of the M1 region (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 5 In this embodiment, the second conductive line 20B is provided on the same layer as the first signal line 10 ( Figure 5 In the figure, the filling pattern of the second conductive line 20B is the same as the filling pattern of the first signal line 10, indicating that they are arranged on the same layer).

[0056] This embodiment explains that the display panel 000 may include multiple metal layers, such as the gate of the driving transistor, the first metal layer where the scan line is located, the second metal layer where the source and drain of the driving transistor are located, the capacitor metal layer where the capacitor structure and the reference voltage line are located, the third metal layer where the power signal line is located, and the fourth metal layer where the data line is located (it can be understood that the design of the above-mentioned film layer structure is only an example, and when implemented specifically, it includes but is not limited to the above-mentioned design structure). When the first signal line 10 of this embodiment is a data line, the first signal line 10 can be located in the fourth metal layer. At this time, the first wire 20A of the different layer from the first signal line 10 can be set in the third metal layer to avoid the line change hole at the connection between the first signal line 10 and the first wire 20A being too deep, which is beneficial to improving process efficiency. In addition, the second portion 20A2 extending along the second direction X in the first wire 20A located in the third metal layer can also overlap with the scan line located in the first metal layer, or the second portion 20A2 extending along the second direction X in the first wire 20A located in the third metal layer can also overlap with the reference voltage line located in the capacitor metal layer, which is beneficial to improving the transmittance of the display panel. Since the second conductive line 20B is disposed on a different layer from the first conductive line 20A, the film layer of the second conductive line 20B needs to avoid the third metal layer. If the second conductive line 20B is disposed on the second metal layer or the capacitor metal layer, it may interfere with other signal traces originally included in the second metal layer or the capacitor metal layer, affecting the transmission of the drive signal of the display panel 000 itself. Therefore, in this embodiment, the second conductive line 20B is disposed on the same layer as the first signal line 10. This not only allows the second conductive line 20B and the first conductive line 20A to be disposed on different layers, thereby ensuring the winding structure of the first connecting line 20, but also allows the second conductive line 20B extending along the first direction Y to avoid the film layer where the first conductive line 20A is located and avoid signal traces extending along the first direction Y in other metal film layers of the display panel, thereby preventing interference between different signals from affecting signal transmission.

[0057] In this embodiment, when the second conductive line 20B is disposed in the same layer as the first signal line 10, since the second conductive line 20B and the first signal line 10 extend in the same direction, the second conductive line 20B and the first signal line 10 do not overlap in the thickness direction of the display panel 000. To improve the transmittance of the display panel 000, this embodiment arranges the first conductive line 20A to be entirely located in the same film layer, and the first conductive line 20A located in the same film layer may include at least one first portion 20A1 and at least one second portion 20A2 extending in different directions, making the winding of the first conductive line 20A more flexible. By adjusting the positions of the first via K1 and the second via K2 at the different-layer connection through the first conductive line 20A extending in different directions, the number of corresponding via holes within the opening area of ​​a sub-pixel can be minimized, thereby further improving the transmittance of the display panel 000.

[0058] In some optional implementations, please refer to Figure 1 、 Figure 3 and Figure 6 , Figure 6 yes Figure 1 Another partially enlarged structural diagram of the M1 region (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 6 In this embodiment, the first conductor 20A of the first connecting line 20 includes two first portions 20A1 and one second portion 20A2, and both ends of the second portion 20A2 are connected to the two first portions 20A1 respectively;

[0059] One end of one first portion 20A1 is electrically connected to the first signal line 10 through the first via K1 , and one end of the other first portion 20A1 is electrically connected to the second conductive line 20B through the second via K2 .

[0060] This embodiment explains that the first conductive line 20A located in the same film layer in the first connecting line 20 includes at least one first portion 20A1 and at least one second portion 20A2 extending in different directions. Optionally, the first conductive line 20A includes two first portions 20A1 and one second portion 20A2, and both ends of one second portion 20A2 are respectively connected to the two first portions 20A1. One end of one of the two first portions 20A1 is electrically connected to the first signal line 10 through a first via K1, and one end of the other first portion 20A1 is electrically connected to the second conductive line 20B through a second via K2. Since the first portion 20A1 extends along the first direction Y, the first conductive line 20A can be extended to the original Figure 3 The first via K1' in the embodiment of the present invention, that is, the first via K1 for connecting the first wire 20A with the first signal line 10, can be set at the position of the first wire change hole K1' in the embodiment of the present invention. Figure 3The first signal line 10 in the related art is connected to the first line-changing hole K1', and the first wire 20A passes through another first portion 20A1 extending along the first direction Y to connect the first signal line 10 with the pixel circuit. Figure 3 The second via K at the position of the third wire-changing hole K3' in the middle of the first conductor 20A and the second conductor 20B is moved down to Figure 6 At the position of the second via K2 in the anode structure 30. In this embodiment, the first conductive wire 20A is set to include both two first parts 20A1 extending along the first direction Y and a second part 20A2 extending along the second direction X, so that the winding of the first conductive wire 20A is more flexible. The anode structure 30 can include only two wire-changing holes below. The position of the first via K1 can be understood as the position of the connection hole where the first signal line 10 of the data line is connected to the pixel circuit, and can also be understood as the position of the connection hole between the first signal line 10 and the first conductive wire 20A of the first connection line 20. The position of the second via K2 can be understood as the position of the connection hole where the first conductive wire 20A of the first connection line 20 of the data line starts to connect to the second conductive wire 20B of the first connection line 20. The first conductive wire 20A is eliminated by the two first parts 20A1 extending along the first direction Y and the second part 20A2 extending along the second direction X, which is originally located at the bottom of the anode structure 30 in the related art. Figure 3 The line-changing hole at the position of the second line-changing hole K2' in the related art is moved to the position of the first line-changing hole K1' where the first signal line 10 is connected to the pixel circuit, and the line-changing hole originally located at the position of the second line-changing hole K2' in the related art is cancelled. Figure 3 The third wire-changing hole K3' is located in the middle of the line-changing hole, and it is further moved down to Figure 6 The position of the second via hole K2 in the anode structure 30 can not only make only two line-changing holes under the anode structure 30, but also improve the problem of display color deviation by reducing the number of line-changing holes at the corresponding position of the anode structure 30 of a sub-pixel P. Figure 6 The positions of the first via K1 and the second via K2 in the Figure 3 The positions of the second line-changing hole K2' and the third line-changing hole K3' in the related art are both moved downward, so the line-changing holes can be moved out of the area where the anode structure 30 is located, further providing a higher possibility for ensuring the flatness of the film layer below the anode structure 30.

[0061] Optional, such as Figure 1 and Figure 2 、 Figure 6As shown, in this embodiment, the display area AA of the display panel 000 includes multiple first electrodes, which can be understood as the anode structure 30 of the sub-pixel. It is understandable that the display panel 000 in this embodiment may also include other structures, such as a cathode layer, a light-emitting functional layer, etc. This embodiment is not described in detail here. Only the example of the display area AA including multiple first electrodes, the first electrode serving as the anode structure 30, and one first electrode corresponding to one sub-pixel is used for illustration. In this embodiment, in the thickness direction of the display panel 000, the first electrode (anode structure 30) overlaps with one first via K1 and / or one second via K2.

[0062] Optionally, in a first via hole K1 and a second via hole K2 that overlap with the same first electrode (anode structure 30), the first via hole K1 and the second via hole K2 correspond to different first connection lines 20. In the thickness direction of the display panel 000, in a first via hole K1 and a second via hole K2 that overlap with the same first electrode (anode structure 30), the first via hole K1 and the second via hole K2 respectively correspond to different first connection lines 20, that is, the first via hole K1 is a connection hole between a first signal line 10 and a first connection line 20, and the second via hole K2 is a connection hole between a first wire 20A and a second wire 20B of a first connection line 20 connected to another first signal line 10. This allows the first electrode overlapping with the first via hole K1 and the second via hole K2 to correspond to one first signal line 10, thereby rationalizing the layout positions of the first electrode and the first signal line 10 of the sub-pixel.

[0063] This embodiment explains that the first conductive wire 20A located in the same film layer in the first connecting wire 20 includes at least one first portion 20A1 and at least one second portion 20A2 extending in different directions. Since the first portion 20A1 extends along the first direction Y, by setting the first conductive wire 20A to include both the first portion 20A1 extending along the first direction Y and the second portion 20A2 extending along the second direction X, the winding of the first conductive wire 20A is more flexible, so that the positions of the first via K1 and the second via K2 at the different-layer connection can be adjusted by the first conductive wire 20A extending in different directions, thereby enabling the display area A to be displayed. The position of the line-changing hole in A is to avoid the first electrode (anode structure 30) as much as possible, so that the first electrode produced later on the first signal line 10 and the first connecting line 20 is as flat as possible, or the position of the first via K1 and the second via K2 at the different-layer connection can be adjusted by the first wire 20A extending in different directions. When the area where the first electrode (anode structure 30) is located cannot be avoided, the number of corresponding line-changing vias within the range of one first electrode (anode structure 30) can be reduced as much as possible, that is, in the thickness direction of the display panel 000, the first electrode (anode structure 30) and a first via K1 (such as Figure 7 As shown, Figure 7 yes Figure 1 Another partially enlarged structural diagram of the M1 region in FIG), or the first electrode (anode structure 30) overlaps with a second via hole K2 (eg Figure 8 As shown, Figure 8 yes Figure 1 Another partially enlarged structural diagram of the M1 region in FIG), or the first electrode (anode structure 30) overlaps with a first via hole K1 and a second via hole K2 (eg Figure 2 and Figure 6 As shown), at least a portion of the first electrode area and a smaller number of line-changing vias are hidden under the first electrode, thereby improving the panel transmittance and providing the possibility for the first vias K1 and the second vias K2 in the display area AA to be arranged as evenly as possible, so as to optimize the winding of the first connecting line 20 connected to the first signal line 10, so that the setting position of the line-changing holes can be flexibly arranged, thereby improving the color deviation problem of the display panel 000, improving the display quality, and improving the user experience.

[0064] In some optional implementations, please refer to Figure 1 、 Figure 5 and Figure 9 , Figure 9 yes Figure 1 Another partially enlarged structural diagram of the M1 region (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 9 In this embodiment, in a first via hole K1 and a second via hole K2 overlapping the same first electrode (the same anode structure 30), the first via hole K1 and the second via hole K2 are located at opposite positions of the first electrode.

[0065] This embodiment explains that the first portion 20A1 and the second portion 20A2 of the first conductive wire 20A of the first connecting wire 20 are arranged in the same layer, that is, the first conductive wire 20A as a whole can be located in the same film layer, but the first conductive wire 20A located in the same film layer includes at least one first portion 20A1 and at least one second portion 20A2 extending in different directions. By setting the first conductive wire 20A to include both the first portion 20A1 extending in the first direction Y and the second portion 20A2 extending in the second direction X, the winding of the first conductive wire 20A can be made more flexible, so that the first conductive wire 20A extending in different directions can be wound around the first conductive wire 20A. 20A is used to adjust the positions of the first via hole K1 and the second via hole K2 at the different-layer connection. Even if the first via hole K1 and the second via hole K2 cannot avoid the area where the first electrode (anode structure 30) is located, the winding method of the first connecting line 20 connected to the first signal line 10 is optimized through the first part 20A1 and the second part 20A2 with different extension directions, so that the corresponding wire-changing holes within the range of one first electrode are arranged as evenly as possible. As shown in the figure, a first via hole K1 and a second via hole K2 overlapping with the same first electrode (the same anode structure 30) are located at two relative positions of the first electrode, as shown in the figure. Figure 5 and Figure 9 As shown, in a first via hole K1 and a second via hole K2 overlapping with the same first electrode, the orthographic projection of the first via hole K1 on the plane where the display panel 000 is located and the orthographic projection of the second via hole K2 on the plane where the display panel 000 is located are respectively located at two diagonal positions of the square; or, the orthographic projection of the first via hole K1 on the plane where the display panel 000 is located and the orthographic projection of the second via hole K2 on the plane where the display panel 000 is located are respectively located at two opposite sides of the square, so that a first via hole K1 and a second via hole K2 are evenly arranged under their corresponding first electrodes, thereby improving the color deviation problem of the display panel 000 and improving the display quality of the display panel 000.

[0066] It is understandable that if Figure 5 and Figure 9 As shown, this embodiment only takes the orthographic projection shape of the main part of the first electrode (i.e., the anode structure 30) on the plane where the display panel 000 is located as a square as an example. In specific implementation, the shape of the main part of the first electrode includes but is not limited to this. In some other optional implementations, the orthographic projection shape of the main part of the first electrode (i.e., the anode structure 30) on the plane where the display panel 000 is located can also be other shapes. This embodiment only takes a square as an example to illustrate the structure when a first via K1 and a second via K2 overlapping with the same first electrode (the same anode structure 30) are located at relative positions of the first electrode.

[0067] In some optional implementations, please refer to Figure 10 and Figure 11 , Figure 10is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Figure 11 yes Figure 10 Another partially enlarged structural diagram of the M2 region (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 11 In this embodiment, the first conductive line 20A includes two first portions 20A1 and two second portions 20A2. One first portion 20A1, one second portion 20A2, another first portion 20A1, and another second portion 20A2 are connected in sequence. Figure 11 The two first portions 20A1 in the schematic diagram are respectively identified by reference numerals 20A11 and 20A12, the two second portions 20A2 are respectively identified by reference numerals 20A21 and 20A22, and the second conductive wire 20B includes a third portion 20B1 extending along the second direction X and a fourth portion 20B2 extending along the first direction Y.

[0068] A first part 20A1 (such as Figure 11 One end of the first portion (numbered 20A11 in FIG. 1 ) is electrically connected to the first signal line 10 through the third via K3, and the other second portion 20A2 (numbered 20A11 in FIG. 1 ) is electrically connected to the first signal line 10 through the third via K3. Figure 11 One end of the second portion (denoted as 20A22) is electrically connected to the third portion 20B1 through a fourth via K4;

[0069] In the thickness direction of the display panel 000, the third portion 20B1 is connected to at least a portion of the other second portion 20A2 (eg Figure 11 The second part (shown as 20A22) overlaps.

[0070] This embodiment explains that at least part of the first conductive line 20A of the first connecting line 20 includes two first portions 20A1 extending along the first direction Y and two second portions 20A2 extending along the second direction X, wherein a first portion 20A1, a second portion 20A2, another first portion 20A1, and another second portion 20A2 of the same film layer are sequentially connected, as shown in FIG. Figure 11 A first part 20A1 (such as Figure 11 One end of the first portion (numbered 20A11 in FIG. 1 ) is electrically connected to the first signal line 10 through the third via K3. A first portion 20A1 (such as FIG. 1 ) is electrically connected to the first signal line 10 through the third via K3. Figure 11 One end of the first part (numbered 20A11 in FIG) is directly connected to a second part 20A2 (such as Figure 11 One end of the second part (numbered 20A21) is connected to a second part 20A2 (such as Figure 11 One end of the second portion (numbered 20A21 in FIG) is directly connected to another first portion 20A1 (such as Figure 11One end of the first part 20A12 is connected to the other first part 20A1 (as shown in FIG. Figure 11 One end of the first portion (numbered 20A12) is directly connected to another second portion 20A2 (such as Figure 11 One end of the second portion 20A22 shown in FIG is connected, and the other second portion 20A2 (such as Figure 11 One end of the second part (numbered 20A22 in the figure) is electrically connected to the third part 20B1 of the second conductive 20B through the fourth via K4 to form a structure in which a first part 20A1, a second part 20A2, another first part 20A1, and another second part 20A2 are connected in sequence in the same film layer, and the connection between the first wire 20A and the second wire 20B arranged in different layers is realized. That is, the first wire 20A of this embodiment can be located in the same film layer as a whole, but the first wire 20A located in the same film layer can include two first parts 20A1 and two second parts 20A2 extending in different directions. By setting the first wire 20A to include both the first part 20A1 extending in the first direction Y and the second part 20A2 extending in the second direction X, the winding of the first wire 20A can be made more flexible, so that the positions of the third via K3 and the fourth via K4 at the different-layer connection can be adjusted by the first wire 20A extending in different directions, and the position of the line-changing hole in the display area AA can be avoided as much as possible from the opening area of ​​the sub-pixel (such as Figure 11 The area PX indicated by the dotted line in the middle) makes the light-emitting functional layer in the sub-pixel opening area above the first signal line 10 and the first connecting line 20 subsequently made as flat as possible, so as to better improve the color deviation problem of the display panel 000 by further optimizing the winding layout of the first connecting line 20 connected to the first signal line 10.

[0071] Optionally, in the thickness direction of the display panel 000 in this embodiment, the third portion 20B1 and at least a portion of the other second portion 20A2 (eg Figure 11 Since the third portion 20B1 of the second wire 20B and the second portion 20A2 of the first wire 20A are both extended along the second direction X, and the second portion 20A2 (as shown in FIG. Figure 11 One end of the second portion (numbered 20A22 in the figure) needs to be electrically connected to the third portion 20B1 of the second conductive portion 20B through the fourth via K4 to achieve signal transmission between the first wire 20A and the second wire 20B of the first connecting line 20. Therefore, in this embodiment, in the thickness direction of the display panel 000, the third portion 20B1 is connected to another second portion 20A2 (such as Figure 11The overlap of the third portion 20B1 and the second portion 20A2 can reduce the space of the display panel 000 occupied by the third portion 20B1 and the second portion 20A2, which is beneficial to further improve the transmittance of the panel.

[0072] Optional, such as Figure 10 and Figure 11 It is shown that in this embodiment, the display area AA of the display panel 000 includes a plurality of first electrodes, and the first electrode can be understood as the anode structure 30 of the sub-pixel; it can be understood that the display panel 000 in this embodiment can also include other structures, such as a cathode layer, a light-emitting functional layer, etc. This embodiment will not be described in detail here, and only the example that the display area AA includes a plurality of first electrodes, the first electrode serves as the anode structure 30, and one first electrode corresponds to one sub-pixel is used for illustration. In this embodiment, in the thickness direction of the display panel 000, at least part of the first electrode (anode structure 30) does not overlap with the third via K3 (not shown in the figure), at least part of the first electrode (anode structure 30) does not overlap with the fourth via K4 (not shown in the figure), and at least part of the first electrode (anode structure 30) does not overlap with both the third via K3 and the fourth via K4 (not shown in the figure). Figure 11 shown).

[0073] This embodiment explains that the first conductive wire 20A located in the same film layer in the first connecting wire 20 includes two first parts 20A1 and two second parts 20A2 extending in different directions. Since the first part 20A1 extends along the first direction Y, by setting the first conductive wire 20A to include both the first part 20A1 extending along the first direction Y and the second part 20A2 extending along the second direction X, the winding of the first conductive wire 20A is made more flexible, so that the positions of the third via K3 and the fourth via K4 at the different-layer connection can be adjusted by the first conductive wire 20A extending in different directions, and the position of the line-changing hole in the display area AA can avoid the first electrode (anode structure 30) as much as possible, so that the first electrode corresponding to a sub-pixel above the first signal line 10 and the first connecting wire 20 made subsequently is as flat as possible, so that the setting position of the line-changing hole can be flexibly arranged by optimizing the winding of the first connecting wire 20 connected to the first signal line 10, thereby further improving the color deviation problem of the display panel 000.

[0074] Optional, such as Figure 1 and Figure 12 Show, Figure 12 yes Figure 1 Another partially enlarged structural diagram of the M1 region (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 12Transparency filling is performed in it), in this embodiment, when the first conductor 20A of the first connecting line 20 includes two first parts 20A1 and one second part 20A2, by moving the first via K1 and the second via K2 downward, the first via K1 and the second via K2 can also be made not to overlap with the first electrode (anode structure 30), so that the positions of the first via K1 and the second via K2 at the different-layer connection can be adjusted by the first conductor 20A extending in different directions, and then the position of the line-changing hole in the display area AA can avoid the first electrode (anode structure 30) as much as possible, so that the first electrode corresponding to a sub-pixel above the first signal line 10 and the first connecting line 20 made subsequently is as flat as possible, so that the setting position of the line-changing hole can be flexibly arranged by optimizing the winding of the first connecting line 20 connected to the first signal line 10, thereby further improving the color deviation problem of the display panel 000.

[0075] In some optional embodiments, the display panel 000 of this embodiment may include a plurality of sub-pixels of different colors, such as at least a red sub-pixel, a green sub-pixel, and a blue sub-pixel. In this case, the first electrode (anode structure 30) corresponding to some sub-pixels (such as the red sub-pixel) in the display panel 000 may not include a line switching hole (such as the hole for switching the first signal line 10 and the first connection line 20) below. Figure 11 As shown in FIG5 , the first electrode corresponding to the sub-pixel above the first signal line 10 and the first connection line 20 is made as flat as possible, thereby improving the color shift problem. Even if the first electrode (anode structure 30) corresponding to some sub-pixels (such as the blue sub-pixel and the green sub-pixel) includes a hole for switching between the first signal line 10 and the first connection line 20, the arrangement of the first conductive wire 20A in the above embodiment can ensure that the number of holes for switching between the first signal line 10 and the first connection line 20 included below the first electrode (anode structure 30) corresponding to a sub-pixel is as small as possible and evenly arranged (such as FIG5 ). Figure 5 As shown), it is beneficial to improve the transmittance of the sub-pixel and also helps to improve the color shift problem.

[0076] In some optional implementations, please refer to Figure 1 、 Figure 10 、 Figure 13 、 Figure 14 and Figure 15 , Figure 13 yes Figure 1 Another schematic diagram of the local magnified structure of the middle M1 region, Figure 14 yes Figure 1 Another schematic diagram of the local magnified structure of the middle M1 region, Figure 15 yes Figure 10 Another partially enlarged structural diagram of the M2 region (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 13-15In this embodiment, the display panel 000 further includes a plurality of compensation signal lines 60. The compensation signal lines 60 are provided in the same layer as the first conductive lines 20A, and the compensation signal lines 60 and the first conductive lines 20A are insulated from each other.

[0077] This embodiment illustrates a design structure in which the first connecting wire 20, which electrically connects the first signal wire 10 in the display area AA to the first conductive pad 401 in the bonding area BA, is disposed in the display area AA. This structure can meet the high-resolution requirements of the display panel 000 while also ensuring display performance and achieving a narrower bezel design for the display panel 000. In this case, the film layer in which the first connecting wire 20 is located can be provided as a separate conductive film layer in the display panel 000, thereby preventing the first connecting wire 20 from affecting the film structure of the display panel 000 itself. For example, the film layer in which the first conductive wire 20A in the first connecting wire 20 is located can be provided as a separate conductive film layer in the display panel 000, thereby achieving a winding structure design for the first conductive wire 20A. Because the film layer structure in which the first conductive wire 20A is located is relatively small, this embodiment configures the display panel 000 to also include multiple compensation signal wires 60 on the same layer as the first conductive wire 20A. Although the compensation signal wires 60 and the first conductive wire 20A are disposed on the same layer, the compensation signal wires 60 and the first conductive wire 20A are insulated from each other. The optional compensation signal line 60 can be used as a virtual signal line in the display panel 000. For example, the display panel 000 also includes a power signal line 70. The power signal line 70 is used to provide a power drive signal for the pixel circuit in the display panel 000. The power signal line 70 is arranged in a different layer from the first signal line 10. For example, the power signal line 70 can be either a positive voltage power signal line or a negative voltage power signal line extending along the second direction X. The power signal line 70 extending along the second direction X is arranged in a different layer from the first signal line 10 of the data line extending along the first direction Y (distinguished by different fill patterns in the figure) to avoid cross-circuiting between the power signal line 70 and the first signal line 10. In this case, the compensation signal line 60 can be electrically connected to the power signal line 70 (for example, by using a different layer line exchange hole to achieve electrical connection) so that the positive voltage power signal is also connected to the compensation signal line 60. This is beneficial for reducing the impedance of the power signal line 70 by utilizing the redundant space of the film layer structure of the display panel 000 itself to set the compensation signal line 60, thereby improving the signal transmission capability of the power signal line 70.

[0078] Optional, such as Figure 1 and Figure 16 As shown, Figure 16 yes Figure 1 Another partially enlarged structural diagram of the M1 region (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 16(The figure shows a transparent filling in the figure). In this embodiment, the power signal line 70 as a positive voltage power signal line or a negative voltage power signal line can also be extended along the first direction Y. At this time, the compensation signal line 60 can also be set in the same layer as the second wire 20B, and the compensation signal line 60 and the second wire 20B are insulated from each other. By electrically connecting the compensation signal line 60 and the power signal line 70 set in different layers, the power signal line 70 can be set in a different layer from the first signal line 10 (distinguished by different filling patterns in the figure). If the first signal line 10 and the second wire 20B are located in the fourth metal layer, and the compensation signal line 60 is also located in the fourth metal layer, then the power signal line 70 can be located in the capacitor metal layer or the second metal layer, etc., to avoid overlapping and short-circuiting the power signal line 70 and the first signal line 10. At this time, the compensation signal line 60 can be electrically connected to the power signal line 70 (such as through a different-layer line exchange hole) so that the compensation signal line 60 in the fourth metal layer is also connected to the positive voltage power signal. This is beneficial for reducing the impedance of the power signal line 70 by setting the compensation signal line 60 by utilizing the redundant space of the film layer structure of the display panel 000 itself, which is beneficial for improving the signal transmission capability of the power signal line 70.

[0079] In some optional implementations, please refer to Figure 17 , Figure 17 1 is a schematic diagram of a planar structure of a display device provided in an embodiment of the present invention. The display device 111 provided in this embodiment includes the display panel 000 provided in the above embodiment of the present invention. Figure 17 This embodiment uses a mobile phone as an example to illustrate the display device 111. It is understood that the display device 111 provided in the embodiment of the present invention can be other display devices 111 with display functions, such as a computer, a television, and an in-vehicle display device, and the present invention does not impose specific limitations on this. The display device 1111 provided in the embodiment of the present invention has the beneficial effects of the display panel 000 provided in the embodiment of the present invention. For details, please refer to the detailed description of the display panel 000 in the above embodiments, and this embodiment will not be repeated here.

[0080] It can be seen from the above embodiments that the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0081] In the display panel provided by this embodiment, at least one first signal line in the display area is connected to the first connecting line, and the first connecting line is provided to include a first conductive wire and a second conductive wire that are connected to each other. The second conductive wire and the first conductive wire are provided in different layers, that is, a first connecting line itself can be provided in two different film layer structures, which can avoid as much as possible the setting of the first connecting line from affecting the film layer wiring structure originally existing in the display area. The first conductive wire and the first signal line are provided in different layers, and need to be connected through a first via at the connection between the first conductive wire and the first signal line. The other end of the first conductive wire is connected to the second conductive wire, and the second conductive wire and the first conductive wire are located in different film layers, and also need to be connected through a second via at the connection between the first conductive wire and the second conductive wire, that is, for the same first connecting wire, at least two wire-changing holes are required to realize the connection between the first connecting wire and the first signal line to complete the transmission of the driving signal. In this embodiment, the first conductive line is arranged so that the entire line can be located in the same film layer, but the first conductive line located in the same film layer can include at least one first portion and at least one second portion extending in different directions. By setting the first conductive line to include both the first portion extending in the first direction and the second portion extending in the second direction, the winding of the first conductive line can be made more flexible, so that the positions of the first via and the second via at the different-layer connection can be adjusted by the first conductive line extending in different directions, and thus the position of the line-changing hole in the display area can be avoided as much as possible from the opening area of ​​the sub-pixel, so that the subsequent light-emitting functional layer in the sub-pixel opening area above the first signal line and the first connecting line can be as flat as possible, or when the opening area of ​​the sub-pixel cannot be avoided, the number of corresponding line-changing holes within the opening area of ​​a sub-pixel can be reduced as much as possible, so as to improve the color deviation problem of the display panel, enhance the display quality, and improve the user experience by optimizing the winding layout of the first connecting line connected to the first signal line.
