Description

Technical Field

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

[0002] Electronic devices with display panels have been popularized in all aspects of life and work. In various electronic devices, especially in mobile terminal products, in order to meet the requirements of users for the display area, the frame of the display panel is continuously compressed to pursue a high screen-to-body ratio. Currently, the display areas of common display panels are all regular rectangles. However, with the development of display technologies, people's requirements for display devices are getting higher and higher. To meet some functional requirements of display devices, in some cases, it is necessary to use an irregular rectangular special-shaped display screen, such as a full-screen display panel with a notch area or a chamfered structure at the panel edge, which has become the mainstream of current special-shaped display panels.

[0003] However, in the designs of some special-shaped display panels proposed in the prior art, it is easy to cause the frame of the panel not to be effectively compressed, thereby affecting the display effect.

[0004] Therefore, providing a display panel and a display device that can effectively compress the width of the frame and achieve a better narrow-frame design whether in a panel structure of a regular shape or in a special-shaped panel structure of an irregular shape is a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0005] In view of this, the present invention provides a display panel and a display device to solve the problem that in the design of the display panel in the prior art, especially for the display panel with a special-shaped structure, the frame cannot be effectively compressed, thereby affecting the display effect.

[0006] The present invention discloses a display panel, including: a display area and a non-display area at least partially surrounding the display area, the non-display area including a bonding area; along a first direction, the bonding area is located on one side of the display area; the display area includes a plurality of first data lines extending along the first direction; the bonding area includes a plurality of first conductive pads, and the first data lines are electrically connected to the first conductive pads through at least one first connection line, the first connection line being located in the display area; the first connection line at least includes a first sub-segment; among the plurality of first sub-segments, the distance between two adjacent first sub-segments is a first distance, and the distance between another two adjacent first sub-segments is a second distance, and the first distance is greater than the second distance.

[0007] Based on the same inventive concept, the present invention also discloses a display device, which includes the above-mentioned display panel.

[0008] Compared with the prior art, the display panel and the display device provided by the present invention achieve at least the following beneficial effects:

[0009] The display panel provided by the present invention includes a display area and a non-display area disposed at least partially around the display area. The display area can be used to set a plurality of sub-pixels, and the sub-pixels are used to achieve the display effect of the display panel. The display area includes a plurality of first data lines extending in a first direction. The non-display area can include a bonding area, and the bonding area includes a plurality of first conductive pads for subsequent bonding electrical connection with a driving chip or a flexible circuit board, so as to provide a driving signal for display for signal traces in the display panel through the driving chip or the flexible circuit board, etc. The first data line is electrically connected to the first conductive pad through at least one first connection line to achieve signal transmission between the first data line and the first conductive pad. The present invention arranges the first connection line in the display area, which can avoid the first connection line occupying the space of the non-display area, especially the lower border of the panel. After the first connection line is connected to the first data line in the display area, the routing path can gradually extend in the direction of approaching the middle area of the display area within the display area range, and then when reaching the edge position of the display area, the fan-out routing connected by the first connection line is as far as possible from the edge area of the display area where the original first data line is located in a second direction, that is, closer to the middle area of the display area, which is beneficial to reducing the width of the lower border area of the non-display area in the second direction, and further can further reduce the lower border of the display panel. The present invention further arranges that the first connection line at least includes a first sub-segment, and the non-equidistant design is adopted between different adjacent two first sub-segments. Further, the routing path of the first connection line in the display area can be flexibly set, so as to be applicable to display areas of different shapes. At the same time, through the flexible routing of the first connection line in the display area, some structures originally used to achieve the display function in the display area can be avoided, such as the original signal traces in the display area, etc., to avoid affecting the display effect of each sub-pixel in the display area. The display panel can also be a display panel with a special-shaped structure including a notch. The non-equidistant design between different adjacent two first sub-segments can make the distance between two adjacent first sub-segments at the notch position large, and the distance between two adjacent first sub-segments at the non-notch position small. By flexibly setting the routing path of the first connection line in the display area, the first connection line can avoid routing in the area where the notch is located, avoiding the need to design a complex winding structure around the notch for the first connection line in the display area in the prior art when the display panel is a special-shaped display panel, which is beneficial to improving the spatial layout effect of the display panel.

[0010] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned technical effects.

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.

Accordingly, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in the embodiments of the present invention can be combined with each other without conflict.

[0028] It should be noted that like reference numerals and letters indicate like items in the following figures, and thus, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0029] Please refer to Figure 1 , Figure 1 which is a schematic plan view of a display panel provided by an embodiment of the present invention. The display panel 000 provided in this embodiment includes: a display area AA and a non-display area NA at least partially surrounding the display area AA. The non-display area NA includes a bonding area BA. Along the first direction Y, the bonding area BA is located on one side of the display area AA. The display area AA includes a plurality of first data lines S1 extending along the first direction Y.

[0030] The bonding area BA includes a plurality of first conductive pads 101. The first data line S1 is electrically connected to the first conductive pad 101 through at least one first connection line 20. The first connection line 20 is located in the display area AA.

[0031] The first connection line 20 includes at least a first sub-segment 20A.

[0032] Among the plurality of first sub-segments 20A, the distance between two adjacent first sub-segments 20A is a first distance D1, and the distance between another two adjacent first sub-segments 20A is a second distance D2. The first distance D1 is greater than the second distance D2.

[0033] Specifically, the display panel 000 provided in this embodiment includes a display area AA and a non-display area NA disposed at least partially around the display area AA. The display area AA can be used to set a plurality of sub-pixels, and the sub-pixels are used to achieve the display effect of the display panel. For example, when the display panel is an organic light-emitting diode display panel, each sub-pixel in the display area AA can include an organic light-emitting diode and a pixel circuit electrically connected thereto; when the display panel is a liquid crystal display panel, each sub-pixel in the display area AA can include a driving transistor, a pixel electrode, etc.; when the display panel 000 is a Micro LED or Mini LED display panel, each sub-pixel in the display area AA can include a light-emitting device such as a Micro LED or a Mini LED. The type of the display panel 000 is not limited in this embodiment, and the structure of the display area AA can be set according to the type of the display panel 000, which will not be elaborated herein. The specific design structure of the sub-pixels in the display area AA can be understood by referring to the structure of the display panel in the related art. The display area AA includes a plurality of first data lines S1 extending along the first direction Y. It can be understood that the first direction Y can be understood as Figure 1 the longitudinal direction in, and the first data line S1 can be understood as part of the data lines in the display area AA of the display panel 000, such as the data lines located in Figure 1 the two side edge regions in the horizontal direction of the display area AA in, and the first data line S1 is used to provide data driving signals for each sub-pixel in this edge region. The non-display area AA can be used to set the driving circuit, driving signal lines, etc. included in the display panel 000, and the driving circuit provides driving signals for signal traces such as scan lines and data lines provided in the display area AA. The non-display area NA can include a bonding area BA. Along the first direction Y, the bonding area BA is located on one side of the display area AA, that is, the bonding area NA can be understood as being located in Figure 1At the lower border of the display panel 000. The bonding area BA of this embodiment includes a plurality of first conductive pads 101. It can be understood that the bonding area BA may also include other conductive pads (not shown in the figure), which are used together with the first conductive pads 101 for subsequent bonding and electrical connection with the driving chip or the flexible circuit board, so as to realize providing driving signals for display and other functions for the signal traces in the display panel 000 through the driving chip or the flexible circuit board. The first data line S1 is electrically connected to the first conductive pad 101 through at least one first connection line 20, realizing signal transmission between the first data line S1 and the first conductive pad 101. In this embodiment, the first connection line 20 is arranged in the display area AA. The first data line S1 is electrically connected to the first conductive pad 101 through at least one first connection line 20 located in the display area AA. It can be understood that the first data line S1 is connected to the first connection line 20 in the display area AA. The first connection line 20 routes within the display area AA to the edge position of the display area AA, and then is connected to the first conductive pad 101 of the bonding area BA through the fan-out trace 30 located in the non-display area NA.

[0034] Optionally, the non-display area NA of this embodiment may further include a fan-out area FA. The fan-out area FA is located between the bonding area BA and the display area AA. The fan-out trace 30 is located in the fan-out area FA. The first connection line 20 is connected to the first conductive pad 101 through at least one fan-out trace 30, realizing the transmission of driving signals between the driving chip or the flexible circuit board bonded in the bonding area BA and the first data line S1 in the display area AA.

[0035] The structure of arranging the first connection line 20 in the display area AA in this embodiment can avoid the first connection line 20 occupying the space of the non-display area NA, especially the lower border in the figure, as Figure 1 shown. After the first connection line 20 is connected to the first data line S1 in the display area AA, the routing path can be gradually extended in the direction approaching the middle area of the display area AA within the display area AA, and then routed to the edge position of the display area AA, so that the fan-out trace 30 connected to the first connection line 20 is as far as possible from the edge area of the display area AA where the original first data line S1 is located in the second direction X (the first direction Y and the second direction X intersect in the direction parallel to the plane where the display panel 000 is located. Optionally, in this embodiment of Figure 1 the present invention, only the example where the first direction Y and the second direction X are perpendicular to each other in the direction parallel to the plane where the display panel 000 is located is taken for illustration). That is, it is closer to the middle area of the display area AA, which is beneficial to reducing the width of the lower border area of the non-display area NA in the second direction X, and further can further reduce the lower border of the display panel 000.

[0036] It can be understood that the design structure in which the first connection line 20 of this embodiment is disposed in the display area AA can meet the requirements of the high resolution of the display panel 000. Even if the number of data lines included in the display panel 000 is larger, the first connection line 20 is routed in the display area AA and does not need to occupy the space of the non-display area NA. Therefore, the width of the non-display area NA in the second direction X can still be further compressed, which can meet the requirements of high resolution while ensuring the display performance and achieving a narrower border.

[0037] In this embodiment, it is further set that the first connection line 20 at least includes a first sub-segment 20A. Optionally, the first sub-segment 20A can be a part of the first connection line 20 extending along the first direction Y (as Figure 1 shown), or can be a part of the first connection line 20 extending along the second direction X (not shown in the figure), and this embodiment does not make a limitation thereto. Among the multiple first sub-segments 20A, the distance between two adjacent first sub-segments 20A is a first distance D1, and the distance between another two adjacent first sub-segments 20A is a second distance D2. The first distance D1 is greater than the second distance D2. By setting different distances between two adjacent first sub-segments 20A, that is, the non-equidistant design between different adjacent first sub-segments 20A, the routing path of the first connection line 20 in the display area AA can be flexibly set. While adapting to display areas AA of different shapes, the flexible routing of the first connection line 20 in the display area AA can also avoid some structures originally used to implement the display function in the display area AA, such as avoiding the original signal routing in the display area AA, so as not to affect the display effect of each sub-pixel in the display area AA.

[0038] In this embodiment Figure 1 Taking the display area AA of the display panel 000 as a regular rectangular shape as an example for illustration, the effect of reducing the lower border of the display panel 000 is achieved through the design that the first connection line 20 is disposed in the display area AA and routed flexibly. It can be understood that in some other alternative embodiments, the display panel 000 can also be a display panel with a special-shaped structure, that is, the display area AA of the display panel 000 can be an irregular and non-rectangular structure. Such as Figure 2 shown Figure 2 is another schematic plan view of the display panel provided by the embodiment of the present invention. In this embodiment Figure 2The display area AA of the illustrated display panel 000 may be a special-shaped structure, such as including a groove K (notch) at the bottom frame position of the display panel 000. In this case, when the first connecting line 20 is routed in the display area AA, by setting a plurality of first sub-segments 20A, the distance between two adjacent first sub-segments 20A is a first distance D1, and the distance between two other adjacent first sub-segments 20A is a second distance D2. The first distance D1 is greater than the second distance D2, so that the distances between different adjacent first sub-segments 20A are different, that is, the distances between different adjacent first sub-segments 20A are designed to be unequal, such as the distance between two adjacent first sub-segments 20A at the groove K position is large, and the distance between two adjacent first sub-segments 20A at the non-groove K position is small. By flexibly setting the routing path of the first connecting line 20 in the display area AA, the first connecting line 20 is routed away from the area where the groove K is located, thereby avoiding the need to design a complex winding structure around the groove K for the first connecting line 20 in the display area AA when the display panel 000 is a special-shaped display panel in the prior art, which affects the spatial layout of the display panel. Therefore, the design structure of the embodiment in which the spacing between two adjacent first sub-segments 20A is unequal can solve the problem of wiring requiring winding in irregularly shaped special-shaped display panels, and is more suitable for special-shaped display panels in the automotive field.

[0039] It can be understood that, in this embodiment, there is no specific limitation on the film layer for making the first connecting line 20. Partial sections of the first connecting line 20 can be made of the film layer included in the panel itself, and the first connecting line 20 can also be made of a separate film layer in the panel. This embodiment does not limit it, and it only needs to satisfy the requirement of not short-circuiting with the signal routing existing in the display area AA. For details, please refer to the structure of the first connecting line 20 in the display area AA in the relevant technology for understanding.

[0040] It should be noted that the figure of this embodiment only illustrates the structure of the display panel. During specific implementation, the display panel 000 may also include other structures capable of realizing the display function, such as a scanning drive circuit and a peripheral wiring located in the non-display area NA, or may also include sub-pixels located in the display area AA, etc., which will not be elaborated in this embodiment. For details, please refer to the structure of the display panel in the relevant technology for understanding.

[0041] In some optional embodiments, please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 3 is another planar structural diagram of a display panel provided by an embodiment of the present invention. In this embodiment, the first connecting line 20 further includes a second sub-segment 20B, and the extension direction of the second sub-segment 20B intersects with the extension direction of the first sub-segment 20A.

[0042] The distance D0 between two adjacent second sub-segments 20B is equal.

[0043] This embodiment explains that the first connection line 20 for electrically connecting the first data line S1 in the display area AA and the first conductive pad 101 in the bonding area BA may include multiple sub-segments. For example, it may not only include the first sub-segment 20A but also the second sub-segment 20B, and the extending directions of the first sub-segment 20A and the second sub-segment 20B intersect. Optionally, in the figure, it is exemplified that the extending direction of the second sub-segment 20B is perpendicular to the extending direction of the first sub-segment 20A. For example, Figure 1 and Figure 2 as shown, the first sub-segment 20A may extend along the first direction Y, then the second sub-segment 20B may extend along the second direction X; as Figure 3 shown, the first sub-segment 20A may extend along the second direction X, then the second sub-segment 20B may extend along the first direction Y. In this embodiment, among the multiple sub-segments of the first connection line 20 extending in different directions, the distance between two adjacent sub-segments in at least one direction is designed with unequal intervals, and the distance between two adjacent sub-segments in another direction is designed with equal intervals. Specifically, for example, Figure 1 and Figure 2 as shown, the first sub-segment 20A extends along the first direction Y, and the second sub-segment 20B extends along the second direction X. The distances between different adjacent first sub-segments 20A are designed with unequal intervals, and the distances between different adjacent second sub-segments 20B are designed with equal intervals. This can make the extending direction of the second sub-segment 20B of the first connection line 20 the same as the extending direction of the scan line or other signal traces in the display panel 000. And when each sub-pixel row is arranged in sequence along the first direction Y, the distances between different adjacent second sub-segments 20B are equal, which can make the position of the second sub-segment 20B as consistent as possible with the scan line. When the second sub-segment 20B and the scan line are arranged in different layers, the second sub-segment 20B can be arranged at the position where the scan line originally was, avoiding the second sub-segment 20B occupying the opening area of the sub-pixels in the display panel 000 and occupying the actual display area of the sub-pixels, thus affecting the display effect. For example, Figure 3As shown, the first sub-segment 20A extends along the second direction X, and the second sub-segment 20B extends along the first direction Y. The distances between different adjacent first sub-segments 20A are designed to be non-uniform, and the distances between different adjacent second sub-segments 20B are designed to be uniform. This can make the extending direction of the second sub-segment 20B of the first connection line 20 the same as the extending direction of the data line or other signal traces in the display panel 000. And when the sub-pixel columns are arranged in sequence along the second direction X, the distances between different adjacent second sub-segments 20B are uniform, which can make the positions of the second sub-segment 20B and the data line as consistent as possible. When the second sub-segment 20B and the data line are arranged in different layers, the second sub-segment 20B can be arranged at the position where the data line originally was, avoiding the second sub-segment 20B occupying the opening area of the sub-pixels in the display panel 000 and occupying the actual display area of the sub-pixels, thus affecting the display effect.

[0044] Optionally, as Figure 2 shown, when the display panel 000 of this embodiment is provided with a groove K at the lower border, then when the non-uniform design is selected for different adjacent two first sub-segments 20A, the first sub-segment 20A extends along the first direction Y, that is, the extending direction of the first sub-segment 20A is Figure 2 the longitudinal direction in

[0045] In some alternative embodiments, please refer to Figure 4 and Figure 5 , Figure 4 which is another schematic plan view of the display panel provided by the embodiment of the present invention. Figure 5 which is another schematic plan view of the display panel provided by the embodiment of the present invention. In this embodiment, the first connection line 20 further includes a second sub-segment 20B, and the second sub-segment 20B extends along the second direction X; wherein, in the direction parallel to the plane where the display panel 000 is located, the first direction Y and the second direction X intersect; in the figure of this embodiment, an example is given with the first direction Y and the second direction X being perpendicular to each other in the direction parallel to the plane where the display panel 000 is located for illustration;

[0046] Among multiple second sub-segments 20B, the distance between two adjacent second sub-segments 20B is the third distance D3, and the distance between another two adjacent second sub-segments 20B is the fourth distance D4, and the third distance D3 is greater than the fourth distance D4.

[0047] This embodiment explains that the first connection line 20 for electrically connecting the first data line S1 in the display area AA and the first conductive pad 101 in the bonding area BA may include a plurality of sub-segments extending in different directions. Optionally, the plurality of sub-segments extending in different directions may form the first connection line 20 including a plurality of bending structures (only one bending structure of the first connection line 20 is schematically shown in the figure). Specifically, the first connection line 20 may include a first sub-segment 20A extending along the first direction Y, and further include a second sub-segment 20B extending along the second direction X. The extending directions of the first sub-segment 20A and the second sub-segment 20B intersect. Optionally, in the figure, the example is given with the extending direction of the second sub-segment 20B being perpendicular to the extending direction of the first sub-segment 20A. In this embodiment, not only is the distance between adjacent two first sub-segments 20A among the plurality of first sub-segments 20A set as the first distance D1, and the distance between another adjacent two first sub-segments 20A is the second distance D2, with the first distance D1 being greater than the second distance D2, but also the distance between adjacent two second sub-segments 20B among the plurality of second sub-segments 20B is set as the third distance D3, and the distance between another adjacent two second sub-segments 20B is the fourth distance D4, with the third distance D3 being greater than the fourth distance D4. That is, among the sub-segments of the first connection line 20 extending in different directions, the non-equidistant design is adopted between different adjacent two first sub-segments 20A, and also between different adjacent two second sub-segments 20B. For example, the distance between adjacent two first sub-segments 20A at the groove K position is large, and the distance between adjacent two first sub-segments 20A at the non-groove K position is small. By flexibly setting the routing path of the first sub-segment 20A of the first connection line 20 in the display area AA, the first connection line 20 can avoid routing through the area where the groove K is located. Also, through the non-equidistant designed second sub-segment 20B, the second sub-segment 20B extending along the second direction X can be flexibly set to avoid the second sub-segment 20B occupying the opening area of the sub-pixels in the display panel 000 and the actual display area of the sub-pixels, and can also avoid the second sub-segment 20B overlapping with the conductive structure in the display panel 000 to generate a coupling effect, which affects the display effect, and thus is beneficial to improving the display quality of the entire display panel.

[0048] In some alternative embodiments, please refer to Figure 6 and Figure 7 , Figure 6 which is another schematic plan view of the display panel provided by the embodiment of the present invention. Figure 7Another schematic plan view of the display panel provided by an embodiment of the present invention. In 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; wherein, in a direction parallel to the plane of the display panel 000, the first direction Y and the second direction X intersect; in the drawings of this embodiment, only the example where the first direction Y and the second direction X are perpendicular to each other in a direction parallel to the plane of the display panel 000 is used for illustration;

[0049] Along the direction from the second display area AA2 to the first display area AA1, the distance between adjacent two first sub-segments 20A gradually increases.

[0050] This embodiment explains that the display area AA of the display panel 000 along the second direction X (i.e., the horizontal direction shown in the figure) may include a first display area AA1 and second display areas AA2 located on opposite sides of the first display area AA1. Then, the first display area AA1 can be understood as the relatively middle display area of the display area AA in the second direction X, and the second display area AA2 can be understood as the relatively edge display area of the display area AA in the second direction X. Optionally, generally, the first data line S1 is located in the second display area AA2, that is, the first data line S1 arranged in the second display area AA2 is connected to the first conductive pad 101 in the bonding area BA through the first connecting line 20 routed in the display area AA, which can make the routing direction of the first connecting line 20 approach the first display area AA, that is, the middle display area, and reduce the width of the bonding area BA in the second direction X, which is beneficial to compressing the width of the lower border in the second direction X. In this embodiment, the first sub-segment 20A of the first connecting line 20 extends along the first direction Y. While the distances between different adjacent two first sub-segments 20A are non-equidistant, it is further set that along the direction from the second display area AA2 to the first display area AA1, the distance between adjacent two first sub-segments 20A shows a gradually increasing trend, that is, the closer to the second display area AA2, the smaller the distance between adjacent two first sub-segments 20A, and the closer to the first display area AA1, the larger the distance between adjacent two first sub-segments 20A. Since there are more fan-out leads and other structures between the bonding area BA and the first display area AA in the middle area, that is, the wiring layout in the fan-out area FA (the range shown as FA1 in the figure) between the first display area AA1 and the bonding area BA is more complex. Therefore, by designing that the closer to the first display area AA1, the larger the distance between adjacent two first sub-segments 20A, the number of wirings in the fan-out area FA (the range shown as FA1 in the figure) between the first display area AA1 and the bonding area BA can be reduced, and thus the wiring difficulty at the lower border of the non-display area NA can be effectively reduced.

[0051] Such as Figure 7As shown, when the display area AA of the display panel 000 is a special-shaped structure, for example, a groove K is included at the lower border position of the display panel 000. At this time, when the first connection line 20 routes in the display area AA, by setting multiple first sub-segments 20A, the distance between two adjacent first sub-segments 20A is the first distance D1, and the distance between another two adjacent first sub-segments 20A is the second distance D2. The first distance D1 is greater than the second distance D2, and along the direction from the second display area AA2 to the first display area AA1, the distance between two adjacent first sub-segments 20A, that is, the closer to the first display area AA1, the greater the distance between two adjacent first sub-segments 20A. This can make two adjacent first sub-segments 20A with a larger distance avoid the area where the groove K is located, and two adjacent first sub-segments 20A with a larger distance can provide a larger opening space for the groove K, which is applicable to special-shaped display panels with irregular shapes, such as special-shaped display panels in the vehicle-mounted field.

[0052] It can be understood that when, in this embodiment, the distance between two adjacent first sub-segments 20A gradually increases along the direction from the second display area AA2 to the first display area AA1, there is no specific limitation on the increasing rule. It can be an irregular increase or a regular increase, as long as it satisfies that the closer to the second display area AA2, the smaller the distance between two adjacent first sub-segments 20A, and the closer to the first display area AA1, the greater the distance between two adjacent first sub-segments 20A.

[0053] Optionally, as Figure 6 and Figure 7 shown, along the direction from the second display area AA2 to the first display area AA1, the distance between two adjacent first sub-segments 20A increases in a geometric progression. As Figure 6 shown, along the second direction X, the distance between two adjacent first sub-segments 20A closest to the edge of the display panel is m1d. Then, when approaching the first display area AA1 in sequence, the distances between two adjacent first sub-segments 20A are m2d, m3d, m4d... respectively, where m2 / m1 = m3 / m2 = m4 / m3..., and m1, m2, m3, m4... are all positive integers; assuming that along the second direction X, the distance between two adjacent first sub-segments 20A closest to the edge of the display panel is d, then when approaching the first display area AA1 in sequence, the distances between two adjacent first sub-segments 20A are 2d, 4d, 8d... respectively; assuming that along the second direction X, the distance between two adjacent first sub-segments 20A closest to the edge of the display panel is 2d, then when approaching the first display area AA1 in sequence, the distances between two adjacent first sub-segments 20A are 4d, 8d, 16d... respectively. In order to achieve a regular and gradual increase in the distance between two adjacent first sub-segments 20A along the direction from the second display area AA2 to the first display area AA1, which is beneficial to improving display uniformity.

[0054] Optionally, as Figure 6 and Figure 7 shown, along the direction from the second display area AA2 to the first display area AA1, among four adjacent first sub-segments 20A, along the direction from the second display area AA2 to the first display area AA1, the distances between two adjacent first sub-segments 20A are A, B, and C in sequence, and B - A = C - B; where A, B, and C are all positive integers. As Figure 6 shown, along the second direction X, if the distance between two adjacent first sub-segments 20A closest to the edge of the display panel is A, then when approaching the first display area AA1 in sequence, the distances between two adjacent first sub-segments 20A are B, C, D... in sequence, where B - A = C - B; assuming that along the second direction X, the distance between two adjacent first sub-segments 20A closest to the edge of the display panel is d, then when approaching the first display area AA1 in sequence, the distances between two adjacent first sub-segments 20A are 2d, 3d, 4d... in sequence; assuming that along the second direction X, the distance between two adjacent first sub-segments 20A closest to the edge of the display panel is 2d, then when approaching the first display area AA1 in sequence, the distances between two adjacent first sub-segments 20A are 4d, 6d, 8d... in order to achieve that the distances between two adjacent first sub-segments 20A gradually increase regularly along the direction from the second display area AA2 to the first display area AA1, which is beneficial to improving the display uniformity.

[0055] In some alternative embodiments, please refer to Figure 2 and Figure 8 , Figure 8 which is another schematic plan view of the display panel provided by the embodiment of the present invention. In this embodiment, the non-display area NA of the display panel 000 includes a first non-display area NA1, and the bonding area BA is located in the first non-display area NA1;

[0056] In the first non-display area NA1, the display panel 000 includes at least one special-shaped edge 01;

[0057] The display panel 000 includes at least one groove K, and the special-shaped edge 01 is recessed towards the display area AA to form the groove K;

[0058] The groove K is located between two adjacent first sub-segments 20A.

[0059] This embodiment explains that the display area AA of the display panel 000 can be an irregular structure. The non-display area NA of the display panel 000 includes a first non-display area NA1, and the bonding area BA is located in the first non-display area NA1. Then, the first non-display area NA1 can be understood as the lower border area of the display panel 000. In the first non-display area NA1, the display panel 000 includes at least one irregular edge 01. The irregular edge 01 is recessed towards the display area AA to form a notch, and this notch is the groove K of the display panel 000. When the first connection line 20 in this embodiment routes in the display area AA, by setting multiple first sub-segments 20A, the non-equidistant design is adopted between different adjacent two first sub-segments 20A, so that the groove K is located between two adjacent first sub-segments 20A with a larger distance, and the distance between two adjacent first sub-segments 20A at non-groove K positions is small. By flexibly setting the routing path of the first connection line 20 in the display area AA, the first sub-segments 20A of two adjacent first connection lines 20 avoid routing in the area where the groove K is located, avoiding the need to design a complex winding structure around the groove K for the first connection line 20 in the display area AA when the display panel 000 is an irregular display panel in the prior art, which affects the spatial layout effect of the display panel.

[0060] Optionally, in this embodiment, the display panel 000 may include two or more grooves K. For example, Figure 8 as shown Figure 8 Taking the display panel 000 including three grooves K as an example for illustration, the shapes of the three grooves K may be the same or different, which is not limited in this embodiment. Then, the non-equidistant design is adopted between different adjacent two first sub-segments 20A, and the routing path of the first sub-segment 20A can be flexibly set to satisfy that the first sub-segments 20A of two adjacent first connection lines 20 avoid routing in the areas where each groove K is located, so as to achieve a narrow border while ensuring the display effect.

[0061] In some alternative embodiments, please refer to Figure 9 , Figure 9 which is another schematic plan view of the display panel provided by the embodiment of the present invention. In this embodiment, multiple first connection lines 20 include a first sub-connection line 201 and a second sub-connection line 202. The length of the first sub-connection line 201 is greater than the length of the second sub-connection line 202, and the width of the first sub-connection line 201 is less than the width of the second sub-connection line 202.

[0062] This embodiment explains that when the first connection line 20 is provided in the display area AA of the display panel 000, and the first data line S1 in the display area AA is electrically connected to the first conductive pad 101 in the bonding area BA through the first connection line 20, the thickness of the first connection line 20 with different lengths can be set differently. Specifically, multiple first connection lines 20 include a first sub-connection line 201 and a second sub-connection line 202. Optionally, the first sub-connection line 201 and the second sub-connection line 202 can be made of the same layer and the same material to reduce the number of film layers of the panel and simplify the manufacturing process. When the length of the first sub-connection line 201 is greater than the length of the second sub-connection line 202, the width of the first sub-connection line 201 can be set to be less than the width of the second sub-connection line 202( Figure 9 (represented by different thicknesses indicating different widths) in Figure 9 to balance the impedance difference between the first connection lines 20 with different lengths, and to improve the stability and uniformity of the driving signals transmitted by the first connection lines 20 with different lengths as much as possible, thereby improving the display effect of the display panel 000.

[0063] It can be understood that this embodiment only exemplifies the implementation manner of balancing impedance by adjusting the thickness of different first connection lines 20. In some other optional implementation manners, the impedance of different first connection lines 20 can also be made as uniform as possible by adjusting the length or other properties of different first connection lines 20, which will not be elaborated in this embodiment.

[0064] In some optional embodiments, please refer to Figure 10 , Figure 10 which is a schematic plan view of the display device provided by the embodiment of the present invention. The display device 111 provided in this embodiment includes the display panel 000 provided by the above embodiment of the present invention. Optionally, the display device 111 in this embodiment can also be a display device with a special-shaped structure. Figure 10 This embodiment only takes a mobile phone as an example to illustrate the display device 111. It can be understood that the display device 111 provided by the embodiment of the present invention can be other display devices 111 with a display function, such as a computer, a television, a vehicle-mounted display device, etc. The present invention does not make specific limitations on this. The display device 111 provided by the embodiment of the present invention has the beneficial effects of the display panel 000 provided by the embodiment of the present invention. For the specific description of the display panel 000, reference can be made to the above embodiments, which will not be elaborated in this embodiment.

[0065] As can be seen from the above embodiments, the display panel and the display device provided by the present invention at least achieve the following beneficial effects:

[0066] The display panel provided by the present invention includes a display area and a non-display area at least partially surrounding the display area. The display area can be used to set a plurality of sub-pixels, and the sub-pixels are used to achieve the display effect of the display panel. The display area includes a plurality of first data lines extending in a first direction. The non-display area can include a bonding area, and the bonding area includes a plurality of first conductive pads, which are used for subsequent bonding electrical connection with a driving chip or a flexible circuit board, so as to realize providing driving signals for display for signal traces in the display panel through the driving chip or the flexible circuit board, etc. The first data line is electrically connected to the first conductive pad through at least one first connection line to realize signal transmission between the first data line and the first conductive pad. In the present invention, the first connection line is arranged in the display area, which can avoid the first connection line occupying the space of the non-display area, especially the lower border area of the panel. After the first connection line is connected to the first data line in the display area, the routing path can extend gradually in the direction close to the middle area of the display area within the display area range, and then when reaching the edge position of the display area, the fan-out routing connected to the first connection line is as far as possible from the edge area of the display area where the original first data line is located in a second direction, that is, closer to the middle area of the display area, which is beneficial to reducing the width of the lower border area of the non-display area in the second direction, and further can further reduce the lower border of the display panel. The present invention further sets that the first connection line at least includes a first sub-segment, and the non-equidistant design is adopted between different adjacent two first sub-segments. Further, the routing path of the first connection line in the display area can be flexibly set, so as to be applicable to display areas of different shapes. At the same time, through the flexible routing of the first connection line in the display area, some structures originally used to realize the display function in the display area can be avoided, such as the original signal traces in the display area, etc., to avoid affecting the display effect of each sub-pixel in the display area. The display panel can also be a display panel with a special-shaped structure including a notch. The non-equidistant design between different adjacent two first sub-segments can make the distance between two adjacent first sub-segments at the notch position large, and the distance between two adjacent first sub-segments at the non-notch position small. By flexibly setting the routing path of the first connection line in the display area, the first connection line can avoid routing in the area where the notch is located, avoiding the need to design a complex winding structure around the notch for the first connection line in the display area in the prior art when the display panel is a special-shaped display panel, which is beneficial to improving the spatial layout effect of the display panel.
