Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light Emitting Diode (OLED) display technology is regarded as the most promising new flat panel display technology for the next generation. Compared with liquid crystal display technology, OLED display technology has the advantages of low energy consumption, low cost, self-luminescence, wide viewing angle and fast response speed. However, the current OLED display panel still has the problem of display abnormality. Summary of the invention

[0003] Based on this, it is necessary to provide a display panel and a display device that can improve display defects.

[0004] In a first aspect, an embodiment of the present application provides a display panel, including:

[0005] substrate;

[0006] A first conductive portion is disposed on the substrate, wherein a surface of the first conductive portion away from the substrate includes a first connection area, and the first conductive portion includes a first side portion and a second side portion;

[0007] A first insulating layer is provided on the substrate and covers a part of the first conductive part away from the substrate, the first insulating layer is provided with a first via hole, and the first via hole exposes the first connection area; the outer edge of the first via hole close to the substrate includes a first sub-side close to the first side portion and a second sub-side close to the second side portion; the orthographic projection of the first sub-side on the substrate is located within the orthographic projection of the first conductive part on the substrate;

[0008] The second conductive portion includes a main body portion and a first connecting portion connected to the main body portion, the main body portion is disposed on a side of the first insulating layer away from the substrate, at least a portion of the first connecting portion is disposed in the first via hole and is connected to the first connecting area; an orthographic projection of the first sub-side on the substrate is disposed between an orthographic projection of the second sub-side on the substrate and an orthographic projection of the main body portion on the substrate;

[0009] The orthographic projection of the second sub-side on the substrate is outside the orthographic projection of the first conductive portion on the substrate; or the orthographic projection of the second sub-side on the substrate overlaps with the orthographic projection of the first conductive portion on the substrate, and the minimum distance between the first sub-side and the first side is greater than the minimum distance between the second sub-side and the second side.

[0010] In the display panel provided by the embodiment of the present application, the orthographic projection of the first sub-side on the substrate is located between the orthographic projection of the second sub-side on the substrate and the orthographic projection of the main body on the substrate, which is equivalent to: in the direction parallel to the surface of the substrate, the first sub-side is located between the second sub-side and the main body, that is, the first sub-side is the side of the first via on the signal transmission direction side, and the second sub-side is the side of the first via on the non-signal transmission direction side. The orthographic projection of the first sub-side on the substrate is located within the orthographic projection of the first conductive part on the substrate, which is equivalent to: the first conductive part has an edge wrapping around the first sub-side. When the orthographic projection of the second sub-side on the substrate is located outside the orthographic projection of the first conductive part on the substrate, the first conductive part does not wrap around the second sub-side. When the orthographic projection of the second sub-side on the substrate overlaps with the orthographic projection of the first conductive part on the substrate, the minimum distance between the first sub-side and the first side portion is greater than the minimum distance between the second sub-side and the second side portion, that is, the edge wrapping value of the first sub-side is greater than the edge wrapping value of the second sub-side. In this way, it is equivalent to making the edging value on the signal transmission direction side greater than the edging value on the non-signal transmission direction side. In this way, the risk of the second conductive part being easily broken at the first sub-edge can be improved, thereby ensuring the signal transmission performance of the second conductive part and reducing the possibility of display abnormalities on the display panel.

DETAILED DESCRIPTION

[0106] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0107] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0108] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0109] In the relevant display panel, there is a problem of display abnormality. After research, the inventor found that when the electrode is connected to the conductive part below through the via hole, the conductive part does not wrap the edge of the signal transmission side of the via hole sufficiently (or does not wrap the edge), causing the edge of the conductive part to be lifted in the via hole, and the electrode on the conductive part and the electrode on the side wall of the via hole are broken, which affects the transmission of the signal and causes the display abnormality problem.

[0110] In view of at least one of the above problems, the embodiments of the present application provide a display panel and a display device, wherein the orthographic projection of the first sub-side on the substrate is located between the orthographic projection of the second sub-side on the substrate and the orthographic projection of the main body on the substrate, which is equivalent to: in the direction parallel to the surface of the substrate, the first sub-side is located between the second sub-side and the main body, that is, the first sub-side is the side of the first via on the signal transmission direction side, and the second sub-side is the side of the first via on the non-signal transmission direction side. The orthographic projection of the first sub-side on the substrate is located within the orthographic projection of the first conductive part on the substrate, which is equivalent to: the first conductive part has an edge wrapping around the first sub-side. When the orthographic projection of the second sub-side on the substrate is located outside the orthographic projection of the first conductive part on the substrate, the first conductive part does not wrap around the second sub-side. When the orthographic projection of the second sub-side on the substrate overlaps with the orthographic projection of the first conductive part on the substrate, the minimum distance between the first sub-side and the first side portion is greater than the minimum distance between the second sub-side and the second side portion, that is, the edge wrapping value of the first sub-side is greater than the edge wrapping value of the second sub-side. In this way, it is equivalent to making the edge value of the signal transmission direction side greater than the edge value of the non-signal transmission direction side, so that the risk of the second conductive part being easily broken at the first sub-side can be improved, thereby ensuring the signal transmission performance of the second conductive part and reducing the possibility of display abnormalities of the display panel. For example, the edge value of the second sub-side is small or there is no edge, reducing the size of the first conductive part is conducive to improving pixel resolution.

[0111] Specifically, refer to Figure 1-Figure 22 As shown, an embodiment of the present application provides a display panel 10, which may be an organic light emitting diode display (Organic Light Emitting Diode, OLED) or a quantum dot electroluminescent display (Quantum Dot Light Emitting Diodes, QLED).

[0112] Specifically, the display panel 10 includes a substrate 11, a first conductive portion 12, a first insulating layer 13, and a second conductive portion 14. The first conductive portion 12 is disposed on the substrate 11, and the surface of the first conductive portion 12 away from the substrate 11 includes a first connection area 12a, and the first conductive portion 12 includes a first side portion 121 and a second side portion 122. The first insulating layer 13 is disposed on the substrate 11 and covers a portion of the first conductive portion 12 away from the substrate 11. The first insulating layer 13 is provided with a first via 13a, and the first via 13a exposes the first connection area 12a; the outer edge of the first via 13a on the side close to the substrate 11 includes a first sub-side 13a1 close to the first side portion 121 and a second sub-side 13a2 close to the second side portion 122. The outer edge of the first via 13a on the side close to the substrate 11 may be equivalent to the contour of the first insulating layer 13 facing and surrounding the side wall of the first via 13a close to the substrate 11.

[0113] The orthographic projection of the first sub-side 13a1 on the substrate 11 is located within the orthographic projection of the first conductive part 12 on the substrate 11, which is equivalent to: the first conductive part 12 has an edge around the first sub-side 13a1. The second conductive part 14 includes a main body 141 and a first connecting part 142 connected to the main body 141. The main body 141 is arranged on the side of the first insulating layer 13 away from the substrate 11. At least part of the first connecting part 142 is located in the first via 13a and connected to the first connecting area 12a. Here, the main body 141 is equivalent to the functional area of ​​the second conductive part 14. The electrical signal is transmitted from the first connecting area 12a of the first conductive part 12 to the first connecting part 142, and then to the main body 141. The orthographic projection of the first sub-side 13a1 on the substrate 11 is located between the orthographic projection of the second sub-side 13a2 on the substrate 11 and the orthographic projection of the main body 141 on the substrate 11. This is equivalent to: in a direction parallel to the surface of the substrate 11, the first sub-side 13a1 is located between the second sub-side 13a2 and the main body 141, that is, the first sub-side 13a1 is the side of the first via 13a on the signal transmission direction side, and the second sub-side 13a2 is the side of the first via 13a on the non-signal transmission direction side. Figure 2 and Figure 3B In the figure, the one-way arrow indicates the direction of signal transmission. Figure 3B Can be along Figure 3A Cross-sectional view along the A1A2 direction.

[0114] Among them, the orthographic projection of the second sub-edge 13a2 on the substrate 11 is located outside the orthographic projection of the first conductive portion 12 on the substrate 11; or, the orthographic projection of the second sub-edge 13a2 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, and the minimum distance between the first sub-edge 13a1 and the first side portion 121 is greater than the minimum distance between the second sub-edge 13a2 and the second side portion 122.

[0115] It is understandable that the substrate 11 may be a flexible substrate 11, such as a polyimide (PI) substrate 11, a polyethylene terephthalate (PET) substrate 11 or a polymethyl methacrylate (PMMA) substrate 11. The substrate 11 may also be a rigid substrate 11, such as glass.

[0116] The display panel 10 provided in the embodiment of the present application is as follows: Fig.12 As shown, when the orthographic projection of the second sub-side 13a2 on the substrate 11 is outside the orthographic projection of the first conductive portion 12 on the substrate 11, the first conductive portion 12 does not surround the second sub-side 13a2. For example, the distance (for example, the minimum distance) between the second sub-side 13a2 and the second side portion 122 may be less than or equal to 0.5 micrometers, for example, 0, 0.1 micrometers, 0.2 micrometers, 0.3 micrometers, 0.4 micrometers, and 0.5 micrometers.

[0117] like Figure 3A and 3B As shown, when the orthographic projection of the second sub-side 13a2 on the substrate 11 overlaps with the orthographic projection of the first conductive part 12 on the substrate 11, the minimum distance a between the first sub-side 13a1 and the first side 121 is greater than the minimum distance b between the second sub-side 13a2 and the second side 122, that is, the edge value of the first sub-side 13a1 is greater than the edge value of the second sub-side 13a2. In this way, it is equivalent to making the edge value of the signal transmission direction side greater than the edge value of the non-signal transmission direction side, so that the risk of the second conductive part 14 being easily broken at the first sub-side 13a1 can be improved, thereby ensuring the signal transmission performance of the second conductive part 14 and reducing the possibility of display abnormalities in the display panel 10.

[0118] It should also be noted that, in the embodiment of the present application, by making the edge value of the first conductive part 12 to the first sub-side 13a1 greater than the edge value of the first conductive part 12 to the second sub-side 13a2, it is equivalent to increasing the edge value of the signal transmission direction side of the first via 13a on the basis of the relevant technology, without increasing the edge value of the second sub-side 13a2 side of the first via 13a. In this way, only a small area needs to be added to the original first conductive part 12 to solve the display abnormality problem, thereby saving the space in the horizontal direction of the display panel 10, which is conducive to high-resolution (PPI) design. The first sub-side 13a1 may be parallel or non-parallel to the first side 121. The second sub-side 13a2 may be parallel or non-parallel to the second side 122. The first sub-side 13a1 may include a straight side, a curved side, or a folded line side. The first side 121 may include a straight side, a curved side, or a folded line side. The second sub-side 13a2 may include a straight side, a curved side, or a folded line side. The second side 122 may include a straight side, a curved side, or a folded line side.

[0119] In one embodiment, if Figure 3A and Figure 4A , Figure 4B As shown, the first conductive portion 12 further includes a third side portion 123, and the first side portion 121, the third side portion 123 and the second side portion 122 are arranged in sequence along the circumference (e.g., the circumference direction) of the first conductive portion 12. The outer edge of the first via 13a on the side close to the substrate 11 also includes a third sub-side 13a3 close to the third side portion 123. The third sub-side 13a3 and the third side portion 123 may be parallel or non-parallel. The third sub-side 13a3 may include a straight side, a curved side, or a zigzag side. The third side portion 123 may include a straight side, a curved side, or a zigzag side.

[0120] In one example, if Fig.13 As shown, the orthographic projection of the third sub-side 13a3 on the substrate 11 is outside the orthographic projection of the first conductive portion 12 on the substrate 11, that is, the first conductive portion 12 does not surround the third sub-side 13a3, so as to reduce the size of the first conductive portion 12, which is beneficial to improve the pixel resolution. For example, the distance (for example, the minimum distance) between the third sub-side 13a3 and the third side portion 123 can be less than or equal to 0.5 microns, for example, 0, 0.1 microns, 0.2 microns, 0.3 microns, 0.4 microns, 0.5 microns.

[0121] In another example, combining Fig.10 As shown, the orthographic projection of the third sub-side 13a3 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, and the minimum distance a between the first sub-side 13a1 and the first side portion 121 is greater than or equal to the minimum distance c between the third sub-side 13a3 and the third side portion 123. That is, the edge value of the first sub-side 13a1 is greater than or equal to the edge value of the third sub-side 13a3.

[0122] For example, the minimum distance a between the first sub-side 13a1 and the first side portion 121 is equal to the minimum distance c between the third sub-side 13a3 and the third side portion 123, that is, the edge value of the first sub-side 13a1 is equal to the edge value of the third sub-side 13a3. In this way, the first connecting portion 142 is not easy to break at the third sub-side 13a3, ensuring that the first connecting portion 142 located on the side wall of the first via hole 13a and the first connecting portion 142 located on the first connection area 12a have a larger connection area, which is conducive to reducing the connection resistance.

[0123] For example, the minimum distance a between the first sub-side 13a1 and the first side portion 121 is greater than the minimum distance c between the third sub-side 13a3 and the third side portion 123, that is, the edge value of the first sub-side 13a1 is greater than the edge value of the third sub-side 13a3. The edge value of the third sub-side 13a3 is smaller, so as to reduce the size of the first conductive portion 12, which is beneficial to improve the pixel resolution.

[0124] In one embodiment, the minimum distance b between the second sub-side 13a2 and the second side portion 122 is equal to the minimum distance c between the third sub-side 13a3 and the third side portion 123. That is, the edge value of the second sub-side 13a2 is equal to the edge value of the third sub-side 13a3. In this way, the edge value of the third sub-side 13a3 is smaller, so as to reduce the size of the first conductive portion 12, which is beneficial to improve the pixel resolution.

[0125] It is understandable that the minimum distance b between the second sub-side 13a2 and the second side portion 122 may be different from the minimum distance c between the third sub-side 13a3 and the third side portion 123. For example, b may be greater than c. For example, b may be less than c.

[0126] In one embodiment, the first conductive portion 12 further includes a fourth side 124, and the first side 121, the third side 123, the second side 122 and the fourth side 124 are arranged in sequence along the circumference of the first conductive portion 12. The outer edge of the first via 13a on the side close to the substrate 11 also includes a fourth sub-side 13a4 close to the fourth side 124. The fourth sub-side 13a4 and the fourth side 124 may be parallel or non-parallel. The fourth sub-side 13a4 may include a straight side, a curved side or a zigzag side. The fourth side 124 may include a straight side, a curved side or a zigzag side.

[0127] In one example, if Fig.14As shown, the orthographic projection of the fourth sub-side 13a4 on the substrate 11 is outside the orthographic projection of the first conductive portion 12 on the substrate 11, that is, the first conductive portion 12 does not surround the fourth sub-side 13a4, so as to reduce the size of the first conductive portion 12, which is beneficial to improve the pixel resolution. For example, the distance (for example, the minimum distance) between the fourth sub-side 13a4 and the fourth side portion 124 can be less than or equal to 0.5 microns, for example, 0.1 microns, 0.2 microns, 0.3 microns, 0.4 microns, 0.5 microns.

[0128] For example, the first conductive portion 12 does not wrap around one or more of the second sub-side 13a2, the third sub-side 13a3, and the fourth sub-side 13a4. Figure 12-14 , Fig.18 , Fig.19 , Fig. 20 , Fig.21 shown.

[0129] In another example, combining Fig.10 As shown, the orthographic projection of the fourth sub-side 13a4 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, and the minimum distance a between the first sub-side 13a1 and the first side portion 121 is greater than or equal to the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. That is, the edge value of the first sub-side 13a1 is greater than or equal to the edge value of the fourth sub-side 13a4.

[0130] For example, the minimum distance a between the first sub-side 13a1 and the first side portion 121 is equal to the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. That is, the edge value of the first sub-side 13a1 is equal to the edge value of the fourth sub-side 13a4. In this way, the first connecting portion 142 is not easy to break at the fourth sub-side 13a4, ensuring that the first connecting portion 142 located on the side wall of the first via 13a and the first connecting portion 142 located on the first connecting region 12a have a larger connection area, which is conducive to reducing the connection resistance.

[0131] In one embodiment, the minimum distance b between the second sub-side 13a2 and the second side portion 122 is equal to the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. That is, the edge value of the second sub-side 13a2 is equal to the edge value of the fourth sub-side 13a4. In this way, the edge value of the fourth sub-side 13a4 is smaller, so as to reduce the size of the first conductive portion 12, which is beneficial to improve the pixel resolution.

[0132] It is understandable that the minimum distance b between the second sub-side 13a2 and the second side portion 122 may be different from the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. For example, b may be greater than d. For example, b may be less than d.

[0133] For example, the minimum distance c between the third sub-side 13a3 and the third side portion 123 and the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124 may be equal or unequal. For example, d may be greater than c. For example, d may be less than c.

[0134] In one embodiment, referring to Figure 5 As shown, the display panel 10 further includes a second insulating layer 15, a third conductive portion 16 and a second connecting portion 17. The second insulating layer 15 is disposed between the film layer where the first conductive portion 12 is located and the substrate 11; the second insulating layer 15 is provided with a second via hole 15a, and the orthographic projection of the first via hole 13a on the substrate 11 is located outside the orthographic projection of the second via hole 15a on the substrate 11, that is, in the thickness direction Z of the display panel 10, the first via hole 13a and the second via hole 15a do not overlap. The orthographic projection of the first via hole 13a on the substrate 11 does not overlap with the orthographic projection of the second via hole 15a on the substrate 11, or the minimum distance between the orthographic projection of the first via hole 13a on the substrate 11 and the orthographic projection of the second via hole 15a on the substrate 11 is greater than 3 microns, for example, greater than 5 microns, for example, 3 microns, 4 microns, 5 microns, 6 microns, and the required edge value of the third sub-side 13a3 and / or the edge value of the fourth sub-side 13a4 is small, which can ensure the reliability of signal transmission and help improve pixel resolution. Figure 5 Can be along Figure 4A The distance between the first via hole 13a and the second via hole 15a is relatively large, which can reduce the influence of the first conductive part 12 on the edge value of each side of the first via hole.

[0135] The third conductive portion 16 is located between the substrate 11 and the second insulating layer 15 . The surface of the third conductive portion 16 away from the substrate 11 includes a second connection region 16 a . The second via hole 15 a exposes the second connection region 16 a .

[0136] The second connection portion 17 is connected to the first conductive portion 12, and the second connection portion 17 is arranged in the same layer as the first conductive portion 12. At least part of the second connection portion 17 is located in the second via 15a and is connected to the second connection area 16a. Multiple structures arranged in the same layer can be obtained by patterning the same film layer, thereby simplifying the process. It is understandable that other film layers can be arranged between the film layer where the third conductive portion 16 is located and the film layer where the first conductive portion 12 is located, and the embodiment of the present application is not limited here.

[0137] It should be noted that the film layer above the via hole area will have fluctuations. The above arrangement prevents the first via hole 13a and the second via hole 15a from overlapping, which can reduce the fluctuation of the second conductive portion 14 at the first via hole 13a, and is beneficial to the production of subsequent film layers.

[0138] Optionally, the second side 122, the third side 123 or the fourth side 124 (for example, one of the second side 122, the third side 123 or the fourth side 124) is connected to the second connection portion 17. Compared with the manner in which multiple sides (such as at least two of the second side 122, the third side 123 and the fourth side 124) are connected to the second connection portion 17, the above arrangement can reduce the arrangement area of ​​the second connection portion 17, which is conducive to high PPI design.

[0139] It is understandable that at least two of the second side portion 122 , the third side portion 123 and the fourth side portion 124 may be connected to the second connecting portion 17 .

[0140] Optional, such as Figure 4A and Figure 4B As shown, the fourth side portion 124 is connected to the second connection portion 17. The orthographic projection of the main body portion 141 on the substrate 11, the orthographic projection of the first side portion 121 on the substrate 11, and the orthographic projection of the second side portion 122 on the substrate 11 are arranged in sequence along the first direction X, and the orthographic projection of the third side portion 123 on the substrate 11, the orthographic projection of the fourth side portion 124 on the substrate 11, and the orthographic projection of the second connection portion 17 on the substrate 11 are arranged in sequence along the second direction Y, and the first direction X and the second direction Y intersect, for example, are perpendicular.

[0141] Or, if Figure 6 As shown, the second side portion 122 is connected to the second connecting portion 17. The orthographic projection of the main body portion 141 on the substrate 11, the orthographic projection of the first side portion 121 on the substrate 11, the orthographic projection of the second side portion 122 on the substrate 11, and the orthographic projection of the second connecting portion 17 on the substrate 11 are sequentially arranged along the first direction X, and the third side portion 123 and the fourth side portion 124 are arranged along the second direction Y, and the first direction X and the second direction Y intersect, for example, are perpendicular.

[0142] The above settings can enable designers to perform layout design according to actual conditions, which is beneficial to improving space utilization and performing high PPI design. It is understandable that the above two different layout methods can be applied to the layout design of the same display panel 10.

[0143] In one embodiment, if Figure 6 As shown, the first conductive part 12 further includes a third side 123, and the first side 121, the third side 123 and the second side 122 are arranged in sequence along the circumference of the first conductive part 12. The outer edge of the first via 13a close to the substrate 11 also includes a third sub-side 13a3 close to the third side 123.

[0144] In one example, the orthographic projection of the third sub-edge 13a3 on the substrate 11 is outside the orthographic projection of the first conductive portion 12 on the substrate 11, that is, the first conductive portion 12 does not surround the third sub-edge 13a3, so as to reduce the size of the first conductive portion 12, which is beneficial to improve pixel resolution.

[0145] In another example, combining Fig.10 As shown, the orthographic projection of the third sub-side 13a3 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, and the minimum distance b between the second sub-side 13a2 and the second side portion 122 is less than or equal to the minimum distance c between the third sub-side 13a3 and the third side portion 123. That is, the edge value of the second sub-side 13a2 is less than or equal to the edge value of the third sub-side 13a3.

[0146] For example, the minimum distance b between the second sub-side 13a2 and the second side portion 122 is equal to the minimum distance c between the third sub-side 13a3 and the third side portion 123. That is, the edge value of the second sub-side 13a2 is equal to the edge value of the third sub-side 13a3. The edge value of the third sub-side 13a3 is smaller, so as to reduce the size of the first conductive portion 12, which is beneficial to improve the pixel resolution.

[0147] For example, the minimum distance b between the second sub-side 13a2 and the second side portion 122 is smaller than the minimum distance c between the third sub-side 13a3 and the third side portion 123. That is, the edge value of the second sub-side 13a2 is smaller than the edge value of the third sub-side 13a3. In this way, the first connection portion 142 is not easily broken at the third sub-side 13a3, ensuring that the first connection portion 142 located on the side wall of the first via hole 13a and the first connection portion 142 located on the first connection area 12a have a larger connection area, which is conducive to reducing the connection resistance.

[0148] In one embodiment, the orthographic projection of the third sub-side 13a3 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, and the minimum distance a between the first sub-side 13a1 and the first side portion 121 is equal to the minimum distance c between the third sub-side 13a3 and the third side portion 123. That is, the edge value of the third sub-side 13a3 is equal to the edge value of the first sub-side 13a1. In this way, the first connecting portion 142 is not easy to break at the third sub-side 13a3, ensuring that the first connecting portion 142 located on the side wall of the first via 13a and the first connecting portion 142 located on the first connecting area 12a have a larger connection area, which is conducive to reducing the connection resistance.

[0149] It is understandable that the minimum distance a between the first sub-side 13a1 and the first side portion 121 and the minimum distance c between the third sub-side 13a3 and the third side portion 123 may not be equal. For example, a may be greater than c.

[0150] In one embodiment, the first conductive portion 12 further includes a fourth side portion 124, and the first side portion 121, the third side portion 123, the second side portion 122 and the fourth side portion 124 are sequentially arranged along the circumference of the first conductive portion 12. The outer edge of the first via 13a on the side close to the substrate 11 further includes a fourth sub-side 13a4 close to the fourth side portion 124.

[0151] In one example, the orthographic projection of the fourth sub-edge 13a4 on the substrate 11 is outside the orthographic projection of the first conductive portion 12 on the substrate 11, that is, the first conductive portion 12 does not surround the fourth sub-edge 13a4, so as to reduce the size of the first conductive portion 12, which is beneficial to improve pixel resolution.

[0152] In another example, combining Fig.10 As shown, the orthographic projection of the fourth sub-side 13a4 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, and the minimum distance b between the second sub-side 13a2 and the second side portion 122 is less than or equal to the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. That is, the edge value of the fourth sub-side 13a4 is less than or equal to the edge value of the second sub-side 13a2.

[0153] For example, the minimum distance b between the second sub-side 13a2 and the second side portion 122 is equal to the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. That is, the edge value of the fourth sub-side 13a4 is equal to the edge value of the second sub-side 13a2. In this way, the edge value of the second sub-side 13a2 is smaller, which is beneficial to saving space in the horizontal direction of the display panel 10, thereby facilitating high PPI design.

[0154] For example, the minimum distance b between the second sub-side 13a2 and the second side portion 122 is smaller than the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. That is, the edge value of the fourth sub-side 13a4 is smaller than the edge value of the second sub-side 13a2. In this way, the first connection portion 142 is not easy to break at the fourth sub-side 13a4, ensuring that the first connection portion 142 located on the side wall of the first via hole 13a and the first connection portion 142 located on the first connection area 12a have a larger connection area, which is conducive to reducing the connection resistance.

[0155] In one embodiment, the orthographic projection of the fourth sub-side 13a4 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, and the minimum distance a between the first sub-side 13a1 and the first side portion 121 is equal to the minimum distance d between the fourth sub-side 13a4 and the fourth side portion 124. In this way, the first connecting portion 142 is not easy to break at the fourth sub-side 13a4, ensuring that the first connecting portion 142 located on the side wall of the first via 13a and the first connecting portion 142 located on the first connecting region 12a have a larger connection area, which is conducive to reducing the connection resistance. In other embodiments, a may be greater than d.

[0156] In one embodiment, if Fig. 9 As shown, the display panel 10 further includes a second insulating layer 15 and a third conductive portion 16, wherein the second insulating layer 15 is disposed between the film layer where the first conductive portion 12 is located and the substrate 11; the second insulating layer 15 is provided with a second via hole 15a; the orthographic projection of the first via hole 13a on the substrate 11 overlaps with the orthographic projection of the second via hole 15a on the substrate 11, which is beneficial to improving the pixel resolution. The orthographic projection of the first via hole 13a on the substrate 11 overlaps with the orthographic projection of the second via hole 15a on the substrate 11, or the minimum distance between the orthographic projection of the first via hole 13a on the substrate 11 and the orthographic projection of the second via hole 15a on the substrate 11 is less than or equal to 3 micrometers, for example, less than or equal to 1 micrometer, for example, 0.5 micrometers, 1 micrometer, 2 micrometers, 3 micrometers, and the required edge value of the third sub-side 13a3 and / or the edge value of the fourth sub-side 13a4 is large to ensure the reliability of signal transmission. Fig. 9 Can be along Figure 7 Cross-sectional view along the C1C2 direction.

Compared with the manner in which multiple sides (such as at least two of the second side 122, the third side 123 and the fourth side 124) are connected to the second connection portion 17, the above arrangement can reduce the arrangement area of ​​the second connection portion 17, which is conducive to high PPI design.

[0171] Optionally, the third side portion 123 extends along the first direction X, and / or the fourth side portion 124 extends along the first direction X, that is, the extension directions of the third side portion 123 and the fourth side portion 124 are parallel to the first direction X.

[0172] Optional, combined Figure 12-Figure 17 As shown, the outer edge of the first via hole 13a on the side close to the substrate 11 is a circle, an ellipse, a rectangle, a rounded rectangle, a polygon with a side length greater than or equal to 5, or a rounded polygon with a side length greater than or equal to 5.

[0174] In one example, if Fig.15 As shown, the first conductive portion 12 is a polygon or a rectangle or a chamfered polygon or a chamfered long side or a rounded rectangle, and the outer edge of the first via 13a on the side close to the substrate 11 is round. The length of the first side of the first conductive portion of the polygon or rectangle or the chamfered polygon or the chamfered long side or the rounded rectangle is less than the length of the third side. The distance between the first side 121 and the second side 122 along the first direction may be greater than the distance between the third side 123 and the fourth side 124 in the second direction.

[0175] In another example, the first conductive portion 12 is a rectangle or a chamfered rectangular shape or a rounded rectangular shape, and the outer edge of the first via hole 13a on the side close to the substrate 11 is a circle or a square or a chamfered rectangular shape or a rounded square shape.

For example, the major axis of the ellipse corresponding to the outer edge of the first via close to the substrate is parallel to the extension direction of the first side. The distance between the first side 121 and the second side 122 along the first direction may be equal to the distance between the third side 123 and the fourth side 124 in the second direction.

[0177] In another example, the first conductive portion 12 is a square or a chamfered square or a rounded square, and the outer edge of the first via hole 13a close to the substrate 11 is an ellipse or a rectangle or a chamfered rectangular shape or a rounded rectangle.

The first via 13a is a polygon, and the polygon has a chamfer. The chamfer can be a straight chamfer (non-rounded chamfer) or a rounded chamfer. By setting a chamfer, such as a rounded corner, a right angle can be avoided, thereby reducing the risk of tip discharge.

In the related art, the minimum distance g between the first side portion 121 and the second side portion 122 is equal to the minimum distance h between the third side portion 123 and the fourth side portion 124. Based on the related art, the embodiment of the present application increases the minimum distance g between the first side portion 121 and the second side portion 122, thereby increasing the minimum distance a between the first sub-side 13a1 and the first side portion 121, so that a is greater than b, c, and d.

[0183] In another example, Fig.11As shown, the maximum dimension e of the first via 13a along the first direction X is smaller than the maximum dimension f of the first via 13a along the second direction Y; the minimum distance g between the first side 121 and the second side 122 is equal to the minimum distance h between the third side 123 and the fourth side 124. In this way, based on the relevant technology, the embodiment of the present application does not increase the area of ​​the first conductive part 12, but adjusts the inner diameter of the first via 13a, thereby increasing the minimum distance a between the first sub-side 13a1 and the first side 121, so that a is greater than b, c, and d. This setting method is conducive to achieving a high PPI design.

[0184] In one embodiment, the display panel 10 further includes a pixel defining layer 18 , which is provided with a pixel opening. The pixel defining layer 18 is located on a side of the film layer where the second conductive portion 14 is located away from the substrate 11 , and the pixel opening exposes at least a portion of the main body 141 .

It can be understood that one of the first electrode 191 and the second electrode 193 is an anode, and the other is a cathode.

[0189] Optional, reference Figure 2 As shown, the second side portion 122 corresponding to the same light-emitting unit 19 is parallel to the fifth side portion 1421 on the side of the first connecting portion 142 corresponding to the light-emitting unit 19 away from the main body 141. That is, the second side portion 122 is parallel to the fifth side portion 1421. In this way, even if the relative orientation of the main body 141 and the first connecting portion 142 is adjusted, it is possible to ensure that the outer edge of the first conductive portion 12 and the outer edge of the first connecting portion 142 remain parallel, which is conducive to having a good hemming amount in all directions of the first via 13a within the limited area of ​​the first conductive portion 12.

[0190] In one embodiment, if Fig. 22As shown, at least one light emitting unit 19 includes a first light emitting unit 19a and a second light emitting unit 19b.

[0192] For example, the orthographic projections of the first via hole and the second via hole corresponding to one of the first light-emitting unit 19a and the second light-emitting unit 19b on the substrate overlap, and the orthographic projections of the first via hole and the second via hole corresponding to the other light-emitting unit 19a on the substrate do not overlap. For example, the orthographic projections of the first via hole and the second via hole corresponding to the first light-emitting unit 19a on the substrate do not overlap, or the minimum distance between the orthographic projection of the first via hole 13a corresponding to the first light-emitting unit 19a on the substrate 11 and the orthographic projection of the second via hole 15a on the substrate 11 is less than or equal to 3 micrometers, for example, less than or equal to 1 micrometer, for example, 0.5 micrometers, 1 micrometer, 2 micrometers, 3 micrometers; the orthographic projections of the first via hole and the second via hole corresponding to the second light-emitting unit 19b on the substrate overlap, for example, the minimum distance between the orthographic projection of the first via hole 13a corresponding to the second light-emitting unit 19b on the substrate 11 and the orthographic projection of the second via hole 15a on the substrate 11 is greater than 3 micrometers, for example, greater than 5 micrometers, for example, 3 micrometers, 4 micrometers, 5 micrometers, 6 micrometers. For example, the minimum distance a between the first sub-side 13a1 corresponding to the second light-emitting unit 19b and the first side 121 is greater than, less than, or equal to the minimum distance a between the first sub-side 13a1 and the first side 121 of the first light-emitting unit 19a. For example, the minimum distance b between the second sub-side 13a2 corresponding to the second light-emitting unit 19b and the second side 122 is greater than, less than, or equal to the minimum distance b between the second sub-side 13a2 and the second side 122 of the first light-emitting unit 19a. For example, the minimum distance c between the third sub-side 13a3 corresponding to the second light-emitting unit 19b and the third side 123 is greater than, less than, or equal to the minimum distance c between the third sub-side 13a3 and the third side 123 of the first light-emitting unit 19a. For example, the minimum distance d between the fourth sub-side 13a4 corresponding to the second light-emitting unit 19b and the fourth side 124 is greater than, less than, or equal to the minimum distance d between the fourth sub-side 13a4 and the fourth side 124 of the first light-emitting unit 19a.

[0193] The above settings allow designers to carry out typesetting design according to actual conditions, which is conducive to improving space utilization and carrying out high PPI design.

Exemplarily, the aperture may be 1.5μm, 2μm, 3μm, 4.2μm or 5μm, etc. The above arrangement allows the first connecting portion 142 to have a sufficient contact area with the first conductive portion 12, which is beneficial to reducing the connection resistance. It should be noted that when the shape of the first via 13a is irregular or polygonal, the aperture refers to the minimum inner diameter of the orthographic projection of the first via 13a.

[0195] Optionally, the aperture of the orthographic projection of the outer edge of the first via hole 13a on the side close to the substrate 11 on the substrate 11 is greater than or equal to 2.5 microns and less than or equal to 3 microns. For example, the aperture may be 2.5 μm, 2.6 μm, 2.7 μm, 2.8 μm, 2.9 μm or 3 μm. The above arrangement, on the one hand, can make the first connecting portion 142 and the first conductive portion 12 have sufficient contact area, and on the other hand, is conducive to achieving a high PPI design.

[0196] Optionally, the first conductive portion 12 includes a plurality of metal layers stacked in sequence along the thickness direction Z of the substrate 11 .

The data signal line 111 and the first conductive part 12 are disposed in the same layer and material and are insulated from each other. In this way, the data signal line 111 and the first conductive part 12 can be manufactured simultaneously in the same process, which is beneficial to reducing the manufacturing cost.

[0200] In this way, the fan-out traces 112 and the first conductive portion 12 can be manufactured simultaneously in the same process, which is beneficial to reducing the manufacturing cost.

Exemplarily, the difference may be 0μm, 1μm, 2μm, 3μm, 4μm, 5μm, etc.

[0204] Optionally, the minimum distance b between the second sub-side 13a2 and the second side portion 122 is greater than or equal to 0. In this way, the risk of the second conductive portion 14 being easily broken at the second sub-side 13a2 can be improved, thereby ensuring the signal transmission performance of the second conductive portion 14 and reducing the possibility of display abnormalities in the display panel 10.

The first insulating layer 13 is disposed on the substrate 11 and covers a part of the side of the first conductive portion 12 away from the substrate 11, and the first insulating layer 13 is provided with a first via 13a, and the first via 13a exposes the first connection area 12a; the outer edge of the first via 13a on the side close to the substrate 11 includes a first sub-side 13a1 close to the first side portion 121, a second sub-side 13a2 close to the second side portion 122, and a third sub-side 13a3 close to the third side portion 123; the orthographic projection of the first sub-side 13a1 on the substrate 11 is located within the orthographic projection of the first conductive portion 12 on the substrate 11. The second conductive portion 14 includes a main body portion 141 and a first connecting portion 142 connected to the main body portion 141. The main body portion 141 is arranged on a side of the insulating layer away from the substrate 11. At least a portion of the first connecting portion 142 is located in the first via hole 13a and connected to the first connecting area 12a.

[0207] Figures 10 to 21 Applicable to Figure 4A , Figure 4B , Figure 6 , Figure 7 , Fig. 8A , Figure 8B , Fig. 22 wait.

[0208] In the display panel 10 provided in the embodiment of the present application, the orthographic projection of the first sub-side 13a1 on the substrate 11 is located between the orthographic projection of the second sub-side 13a2 on the substrate 11 and the orthographic projection of the main body 141 on the substrate 11, which is equivalent to: in the direction parallel to the surface of the substrate 11, the first sub-side 13a1 is located between the second sub-side 13a2 and the main body 141, that is, the first sub-side 13a1 is the side of the first via 13a on the signal transmission direction side, and the second sub-side 13a2 and the third sub-side 13a3 are the side of the first via 13a on the non-signal transmission direction side. The orthographic projection of the first sub-side 13a1 on the substrate 11 is located within the orthographic projection of the first conductive part 12 on the substrate 11, which is equivalent to: the first conductive part 12 has an edge around the first sub-side 13a1. When the orthographic projection of the third sub-side 13a3 on the substrate 11 is located outside the orthographic projection of the first conductive part 12 on the substrate 11, the first conductive part 12 does not have an edge around the third sub-side 13a3. When the orthographic projection of the third sub-side 13a3 on the substrate 11 overlaps with the orthographic projection of the first conductive portion 12 on the substrate 11, the minimum distance between the first sub-side 13a1 and the first side portion 121 is greater than the minimum distance between the third sub-side 13a3 and the second side portion 122, that is, the edge value of the first sub-side 13a1 is greater than the edge value of the third sub-side 13a3.
