DETAILED DESCRIPTION

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0068] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.

[0069] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0070] In the description of this application, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0071] It should be noted that, in the absence of conflict, different features in the embodiments of the present application can be combined with each other.

[0072] The display panel in the related art includes a substrate, a conductive layer located on one side of the substrate, a pixel defining layer located on the side of the conductive layer away from the substrate, and a light-emitting unit located in the pixel opening of the pixel defining layer. The light-emitting unit includes a light-emitting functional part, and the light-emitting functional part includes a multi-layer stacked film layer.

[0073] After long-term research, the inventors found that in the related technology, when the display panel is subjected to external loads, such as when it is folded inward, the film layer of the light-emitting functional part will be subjected to the stress of the conductive traces in the conductive layer, which will make the film layers of the light-emitting functional part easily separate from each other, and then cause the corresponding light-emitting units to produce black spots, which ultimately affects the display effect of the display panel.

[0074] In order to solve the above-mentioned technical problems, the inventors have innovatively designed the following technical solutions, and the specific implementation solutions of this application will be described in detail below with reference to the accompanying drawings. It should be noted that the defects existing in the solutions in the above-mentioned prior art are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above-mentioned technical problems and the solutions proposed in this embodiment below for the above-mentioned problems should all be the contributions made by the inventors to this application in the process of invention and creation, and should not be understood as technical contents known to those skilled in the art.

[0075] See Figure 1 and Figure 2 This embodiment provides a display panel, which includes a substrate 1, a conductive layer 2, a pixel defining layer 4 and a light-emitting unit 5.

[0076] The conductive layer 2 is located on one side of the substrate 1 . The conductive layer 2 includes a first conductive trace 3 . There may be multiple first conductive traces 3 .

[0077] The pixel defining layer 4 is located on the side of the conductive layer 2 away from the substrate 1 . The pixel defining layer 4 includes a pixel opening 41 . The edge of the orthographic projection of the pixel opening 41 on the substrate 1 is staggered with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 .

[0078] At least a portion of the light emitting unit 5 is located within the pixel opening 41 .

[0079] After further research by the inventors, it was found that the side of the light-emitting functional portion 52 of the light-emitting unit 5 close to the edge of the pixel opening 41 is uneven, and the stress of the light-emitting functional portion 52 at the edge of the pixel opening 41 is more concentrated, that is, the stress exerted on the light-emitting functional portion 52 of the light-emitting unit 5 at the edge of the pixel opening 41 is greater than the stress exerted on the light-emitting functional portion 52 at other positions of the pixel opening 41 and on the side of the pixel defining layer 4 away from the substrate 1.

[0080] In the related art, the edges of the positive projections of the first conductive trace 3 and the pixel opening 41 on the substrate 1 are at least partially parallel, and at least partially overlap. In this way, when the display panel is bent, the edge of the first conductive trace 3 exerts greater stress on the light-emitting functional part 52 located at the edge of the pixel opening 41, making it easier for the film layers in the light-emitting functional part 52 to separate from each other at the edge of the pixel opening 41.

[0081] In this embodiment, the edge of the orthographic projection of the pixel opening 41 on the substrate 1 is set to be staggered with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the edge of the orthographic projection of the pixel opening 41 on the substrate 1 does not overlap with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the edge of the orthographic projection of the pixel opening 41 on the substrate 1 and the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 are arranged at intervals.

[0082] In this way, when the display panel is bent, the stress generated by the edge of the first conductive trace 3 is not easily directly applied to the film layer of the light-emitting functional part 52 at the edge of the pixel opening 41, thereby reducing the stress on the film layer of the light-emitting functional part 52 at the edge of the pixel opening 41, making it difficult for the film layers of the light-emitting functional part 52 to separate from each other at the edge of the pixel opening 41, and further making it difficult for the corresponding light-emitting unit 5 to produce black spots, which can ultimately improve the display effect of the display panel.

[0083] Based on the above design, this embodiment sets the edge of the positive projection of the pixel opening 41 on the substrate 1 to be staggered with the edge of the positive projection of the first conductive trace 3 on the substrate 1, so that the film layers of the light-emitting functional part 52 are not easily separated from each other at the edge of the pixel opening 41, thereby making it less likely that the corresponding light-emitting unit 5 will produce black spots, thereby improving the display effect of the display panel.

[0084] For some possible implementations, see Figure 3 and Figure 4 The display panel further includes a plurality of support columns 6 spaced apart on a side of the pixel defining layer 4 away from the substrate 1 , and the edges of the orthographic projections of the support columns 6 on the substrate 1 are staggered with the edges of the orthographic projections of the first conductive traces 3 on the substrate 1 .

[0085] Optionally, a distance H1 between the side of the support column 6 away from the substrate 1 and the substrate 1 is greater than a distance H2 between the side of the pixel defining layer 4 away from the substrate 1 and the substrate 1. The support column 6 can be used to support the mask during the manufacturing process of the display panel. Therefore, it is not necessary to set a support column 6 on the side of the pixel defining layer 4 away from the substrate 1 next to each light-emitting unit 5. Support columns 6 only need to be set on the side of the pixel defining layer 4 away from the substrate 1 next to certain light-emitting units 5.

[0086] After further research, the inventors found that the side of the light-emitting functional part 52 of the light-emitting unit 5 close to the edge of the support column 6 is uneven, and the stress of the light-emitting functional part 52 at the edge of the support column 6 is more concentrated, that is, the stress exerted on the light-emitting functional part 52 of the light-emitting unit 5 at the edge of the support column 6 is greater than the stress exerted on the light-emitting functional part 52 on the side of the pixel defining layer 4 away from the substrate 1.

[0087] In the related art, the edges of the positive projections of the first conductive trace 3 and the support column 6 on the substrate 1 are at least partially parallel, and at least partially overlap. When the display panel is bent, the edge of the first conductive trace 3 exerts greater stress on the light-emitting functional part 52 located at the edge of the support column 6, making it easier for the film layers in the light-emitting functional part 52 of the light-emitting unit 5 to separate from each other at the edge of the support column 6.

[0088] If the orthographic projection of the support column 6 on the substrate 1 is set to be staggered with the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the orthographic projection of the support column 6 on the substrate 1 and the orthographic projection of the first conductive trace 3 on the substrate 1 do not overlap, then as the pixel density of the screen becomes higher and higher, the first conductive trace 3 will become more and more dense, making it difficult to set the orthographic projection of the support column 6 on the substrate 1 to be staggered with the orthographic projection of the first conductive trace 3 on the substrate 1.

[0089] In this embodiment, the edge of the orthographic projection of the support column 6 on the substrate 1 is set to be staggered with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the edge of the orthographic projection of the support column 6 on the substrate 1 does not overlap with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the edge of the orthographic projection of the support column 6 on the substrate 1 and the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 are arranged at intervals.

[0090] In this way, when the display panel is bent, the stress generated by the edge of the first conductive trace 3 is not easily directly applied to the film layer of the light-emitting functional part 52 at the edge of the support column 6, thereby reducing the stress on the film layer of the light-emitting functional part 52 located at the edge of the support column 6, making it difficult for the film layers of the light-emitting functional part 52 to separate from each other at the edge of the pixel opening 41, and further making it difficult for the corresponding light-emitting unit 5 to produce black spots, which can ultimately improve the display effect of the display panel.

[0091] In addition, this embodiment does not completely avoid the first conductive trace 3 from the support column 6, that is, the orthographic projections of the first conductive trace 3 and the support column 6 on the substrate 1 can be allowed to at least partially overlap. It is only necessary to avoid the edges of the orthographic projection of the support column 6 on the substrate 1 and the edges of the orthographic projection of the first conductive trace 3 on the substrate 1. This can increase the space for setting the support column 6, reduce the difficulty of setting the relative positions of the first conductive trace 3 and the support column 6, and improve the feasibility of the solution.

[0092] Preferably, the orthographic projection of the support column 6 on the substrate 1 is outside the orthographic projection of the light emitting unit 5 on the substrate 1. In this way, the support column 6 is not likely to affect the normal display of the light emitting unit 5.

[0093] Preferably, see Figure 4 and Figure 5 The light emitting unit 5 includes a first electrode 51 , a light emitting functional portion 52 , and a second electrode 53 stacked in sequence in a direction away from the substrate 1 , and the pixel opening 41 exposes a portion of the first electrode 51 .

[0094] Optionally, the light-emitting functional portion 52 includes a hole injection layer 521, a hole transport layer 522, a light-emitting layer 523, an electron transport layer 524 and an electron injection layer 525 stacked in sequence in a direction away from the substrate 1, and at least two layers of the hole injection layer 521, the hole transport layer 522, the electron transport layer 524 and the electron injection layer 525 cover the support column 6.

[0095] The hole injection layer 521, the hole transport layer 522, the electron transport layer 524 and the electron injection layer 525 in this embodiment all cover the support column 6. Through the scheme in the above embodiment, the hole injection layer 521, the hole transport layer 522, the electron transport layer 524 and the electron injection layer 525 are not easily separated, so that the corresponding light-emitting unit 5 is not prone to black spots.

[0096] For some possible implementations, see Figure 6-Figure 8 The display panel 7 includes a bending zone WZ, and an edge of an orthographic projection of the pixel opening 41 located in the bending zone WZ on the substrate 1 is staggered from an edge of an orthographic projection of the first conductive trace 3 on the substrate 1 .

[0097] Optionally, an edge of an orthographic projection of the support pillar 6 located in the bending zone WZ on the substrate 1 is staggered from an edge of an orthographic projection of the first conductive trace 3 on the substrate 1 .

[0098] Normally, in a folding screen, the display panel 7 is bent to a greater extent, and the area in the folding screen that is bent is the bending zone WZ.

[0099] In this embodiment, only the edge of the pixel opening 41 of the display panel 7 in the bending zone WZ and the orthographic projection of the support column 6 on the substrate 1 can be set to be staggered with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1. In this way, the difficulty of preparing the display panel 7 can be reduced.

[0100] Specifically, the edge of the orthographic projection of the pixel opening 41 located in the bending zone WZ on the substrate 1 is located on a side of the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 away from the center of the pixel opening 41 .

[0101] Preferably, the edge of the orthographic projection of the support pillar 6 located in the bending zone WZ on the substrate 1 is located on a side of the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 away from the center of the pixel opening 41 .

[0102] In short, no matter how the relative positions of the pixel opening 41, the support column 6 and the first conductive trace 3 are arranged, it is necessary to ensure that the edges of the positive projections of the pixel opening 41 and the support column 6 located in the bending zone WZ on the substrate 1 are staggered with the edges of the positive projections of the first conductive trace 3 on the substrate 1.

[0103] For some possible implementations, see again Figure 6 and Figure 7 The minimum distance N1 between the edge of the orthographic projection of the pixel opening 41 in the bending zone WZ on the substrate 1 and the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 is greater than or equal to 0.5 μm and less than or equal to 10 μm.

[0104] For example, the minimum distance N1 can be 0.5μm, 1μm, 2μm, 3μm, 4μm, 5μm, 6μm, 7μm, 8μm, 9μm, or 10μm. If the minimum distance N1 is set too small, the edge of the first conductive trace 3 may affect the film layer of the light-emitting functional portion 52 located at the edge of the pixel opening 41, increasing the risk of the film layer of the light-emitting functional portion 52 separating at the edge of the pixel opening 41. If the minimum distance N1 is set too large, it will increase the difficulty of designing the relative position of the first conductive trace 3 and the pixel opening 41. Therefore, a reasonable setting of the minimum distance N1 can prevent the film layer of the light-emitting functional portion 52 from separating from each other at the edge of the pixel opening 41 and make it easier to design the relative position of the first conductive trace 3 and the pixel opening 41.

[0105] Preferably, the minimum distance N2 between the edge of the orthographic projection of the support pillar 6 in the bending zone WZ and the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 is greater than or equal to 0.5 μm and less than or equal to 10 μm.

[0106] For example, the minimum distance N2 can be 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, or 10 μm. If the minimum distance N2 is set too small, the edge of the first conductive trace 3 may affect the film layer of the light-emitting functional portion 52 located at the edge of the support pillar 6, increasing the risk of the film layer of the light-emitting functional portion 52 separating at the edge of the support pillar 6. If the minimum distance N2 is set too large, it will increase the difficulty of designing the relative position of the first conductive trace 3 and the support pillar 6. Therefore, a reasonable setting of the minimum distance N2 can prevent the film layer of the light-emitting functional portion 52 from separating at the edge of the support pillar 6 and make it easier to design the relative position of the first conductive trace 3 and the support pillar 6.

[0107] Preferably, see Figure 6-Figure 9 The orthographic projection of the pixel opening 41 located in the bending zone WZ on the substrate 1 includes a first edge 411, the first edge 411 is staggered with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1, and the first edge 411 is parallel to the bending axis 8 of the bending zone WZ.

[0108] When the display panel is folded, the display panel will be folded along the bending axis 8 of the bending zone WZ. For example, if the screen is folded along the row direction of the screen, the bending axis 8 of the display panel extends along the row direction of the screen, and the first edge 411 extends along the row direction of the screen.

[0109] When the display panel is bent, the edge of the first conductive trace 3 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the first edge 411. In this embodiment, only the first edge 411 can be arranged to be offset from the edge of the orthographic projection of the first conductive trace 3 on the substrate 1. That is, when manufacturing the display panel, only the first edge 411 of the pixel opening 41 can be arranged to avoid the edge of the first conductive trace 3. This makes it easier to adjust the relative position between the first conductive trace 3 and the pixel opening 41 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0110] Preferably, see again Figure 6-Figure 9 The positive projection of the support column 6 located in the bending zone WZ on the substrate 1 includes a second edge 61, the second edge 61 is staggered with the edge of the positive projection of the first conductive trace 3 on the substrate 1, and the second edge 61 is parallel to the bending axis 8 of the bending zone WZ.

[0111] When the display panel is bent, the edge of the first conductive trace 3 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the second edge 61. In this embodiment, only the second edge 61 can be arranged to be offset from the edge of the orthographic projection of the first conductive trace 3 on the substrate 1. That is, when manufacturing the display panel, only the second edge 61 of the support pillar 6 can be arranged to avoid the edge of the first conductive trace 3. This makes it easier to adjust the relative position between the first conductive trace 3 and the support pillar 6 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0112] Preferably, the orthographic projection of the first conductive trace 3 in the bending zone WZ on the substrate 1 includes a third edge 31 , the first edge 411 is staggered from the third edge 31 , and the third edge 31 is parallel to the bending axis 8 of the bending zone WZ.

[0113] The third edge 31 does not only refer to an edge of the positive projection of the first conductive trace 3 on the substrate 1. Among the edges of the positive projection of all the first conductive traces 3 on the substrate 1 in the bending zone WZ, as long as the edges are parallel to the bending axis 8 of the bending zone WZ can be regarded as the third edge 31.

[0114] When the display panel is bent, the third edge 31 of the first conductive trace 3 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the first edge 411. In this embodiment, only the first edge 411 can be offset from the third edge 31. That is, when manufacturing the display panel, only the first edge 411 of the pixel opening 41 can be aligned away from the third edge 31 of the first conductive trace 3. This makes it easier to adjust the relative position between the first conductive trace 3 and the pixel opening 41 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0115] Preferably, the second edge 61 is staggered from the third edge 31 .

[0116] When the display panel is bent, the third edge 31 of the first conductive trace 3 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the second edge 61. In this embodiment, only the second edge 61 can be offset from the third edge 31. That is, when manufacturing the display panel, only the second edge 61 of the support pillar 6 can be aligned away from the third edge 31 of the first conductive trace 3. This makes it easier to adjust the relative position between the first conductive trace 3 and the support pillar 6 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0117] Preferably, the minimum distance W1 between the first edge 411 and the third edge 31 is greater than or equal to 0.5 μm and less than or equal to 10 μm.

[0118] For example, the minimum distance W1 can be 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, or 10 μm. If the minimum distance W1 is set too small, the third edge 31 may affect the film layer of the light-emitting functional portion 52 located at the first edge 411, increasing the risk of the film layer of the light-emitting functional portion 52 separating at the first edge 411. If the minimum distance W1 is set too large, it will increase the difficulty in designing the relative position between the first conductive trace 3 and the pixel opening 41. Therefore, a reasonable setting of the minimum distance W1 can prevent the film layer of the light-emitting functional portion 52 from separating at the first edge 411 and make it easier to design the relative position between the first conductive trace 3 and the pixel opening 41.

[0119] Preferably, a minimum distance D1 between the second edge 61 and an edge of an orthographic projection of the first conductive trace 3 on the substrate 1 is greater than or equal to 0.5 μm and less than or equal to 10 μm.

[0120] For example, the minimum distance D1 can be 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, or 10 μm. If the minimum distance D1 is set too small, the third edge 31 may affect the film layer of the light-emitting functional portion 52 located at the second edge 61, increasing the risk of the film layer of the light-emitting functional portion 52 separating at the second edge 61. If the minimum distance D1 is set too large, it will increase the difficulty in designing the relative position between the first conductive trace 3 and the support pillar 6. Therefore, a reasonable setting of the minimum distance D1 can prevent the film layer of the light-emitting functional portion 52 from separating at the second edge 61 and make it easier to design the relative position between the first conductive trace 3 and the support pillar 6.

[0121] For some possible implementations, see again Figure 7-Figure 8The conductive layer 2 includes multiple conductive sublayers stacked in sequence between the substrate 1 and the pixel defining layer 4 in a direction away from the substrate 1 , and the first conductive trace 3 is located in a conductive sublayer closest to the pixel defining layer 4 .

[0122] The conductive sublayer can be a metal layer, and the material of the pixel defining layer 4 includes organic material. The modulus or stiffness of the organic material is much lower than that of the metal layer, which makes the conductive traces in the conductive sublayer closest to the pixel defining layer 4 exert greater stress on the film layer of the light-emitting functional part 52.

[0123] In this embodiment, only the relative positions of the first conductive trace 3 in the conductive sublayer closest to the pixel defining layer 4 and the pixel opening 41 and the support column 6 can be designed as in the above embodiment. In this way, the relative positions between the multiple conductive sublayers and the pixel opening 41 and the support column 6 can be more easily set without making the film layer of the light-emitting functional part 52 difficult to separate.

[0124] Preferably, see again Figure 7-Figure 8 The multilayer conductive sublayer includes a first conductive sublayer 9, a second conductive sublayer 10, a third conductive sublayer 11 and a fourth conductive sublayer 12 stacked in sequence in a direction away from the substrate 1, and the first conductive trace 3 is located in the fourth conductive sublayer 12.

[0125] In this embodiment, the fourth conductive sublayer 12 is closest to the pixel defining layer 4. When the display panel is bent, the first conductive trace 3 in the fourth conductive sublayer 12 located in the bending zone WZ has the greatest impact on the film layer of the light-emitting functional part 52. By designing the first conductive trace 3 in the fourth conductive sublayer 12 according to the above embodiment, the film layer of the light-emitting functional part 52 is not easily separated.

[0126] Preferably, the display panel further includes a first organic layer 13 and a second organic layer 14 . The first organic layer 13 is located between the third conductive sublayer 11 and the fourth conductive sublayer 12 . The second organic layer 14 is located between the fourth conductive sublayer 12 and the pixel defining layer 4 .

[0127] The materials of the first organic layer 13 and the second organic layer 14 both include organic materials. When the display panel is bent, the stress generated by the conductive traces in the third conductive sublayer 11 will also affect the film layer in the light-emitting functional part 52. Therefore, the conductive traces in the third conductive sublayer 11 in the bending zone WZ can also be designed similarly to the first conductive traces 3 in the above embodiment.

[0128] Since the insulating layer between the first conductive sublayer 9 and the second conductive sublayer 10, and the insulating layer between the second conductive sublayer 10 and the third conductive sublayer 11 both include inorganic materials, and the first conductive sublayer 9 and the second conductive sublayer 10 are farther away from the light-emitting functional part 52, when the display panel is bent, the stress exerted on the light-emitting functional part 52 by the conductive traces in the first conductive sublayer 9 and the second conductive sublayer 10 located in the bending zone WZ is relatively small. Therefore, the conductive traces in the first conductive sublayer 9 and the second conductive sublayer 10 located in the bending zone WZ may not be designed similarly to the first conductive trace 3 in the above embodiment, thereby reducing the difficulty of designing the relative positions between the conductive traces in the first conductive sublayer 9 and the second conductive sublayer 10 and the pixel opening 41 and the support column 6.

[0129] Specifically, see Figure 7-10 The third conductive sublayer 11 includes a second conductive trace 111 , and the first edge 411 is staggered from the edge of the orthographic projection of the second conductive trace 111 on the substrate 1 .

[0130] When the display panel is bent, the edge of the second conductive trace 111 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the first edge 411. In this embodiment, only the first edge 411 can be arranged to be offset from the edge of the orthographic projection of the second conductive trace 111 on the substrate 1. That is, when manufacturing the display panel, only the first edge 411 of the pixel opening 41 can be arranged to avoid the edge of the second conductive trace 111. This makes it easier to adjust the relative position between the second conductive trace 111 and the pixel opening 41 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0131] Preferably, the second edge 61 is staggered from the edge of the orthographic projection of the second conductive trace 111 on the substrate 1 .

[0132] When the display panel is bent, the edge of the second conductive trace 111 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the second edge 61. In this embodiment, only the second edge 61 can be positioned to be offset from the edge of the orthographic projection of the second conductive trace 111 on the substrate 1. That is, when manufacturing the display panel, only the second edge 61 of the support pillar 6 can be positioned away from the edge of the second conductive trace 111. This makes it easier to adjust the relative position between the second conductive trace 111 and the support pillar 6 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0133] Preferably, the orthographic projection of the second conductive trace 111 in the bending zone WZ on the substrate 1 includes a fourth edge 1111 , the first edge 411 is staggered from the fourth edge 1111 , and the fourth edge 1111 is parallel to the bending axis 8 of the bending zone WZ.

[0134] The fourth edge 1111 does not only refer to an edge of the positive projection of the second conductive trace 111 on the substrate 1. Among all the edges of the positive projection of the second conductive trace 111 on the substrate 1 in the bending zone WZ, as long as the edges are parallel to the bending axis 8 of the bending zone WZ can be regarded as the fourth edge 1111.

[0135] When the display panel is bent, the fourth edge 1111 of the second conductive trace 111 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the first edge 411. In this embodiment, only the first edge 411 can be offset from the fourth edge 1111. That is, when manufacturing the display panel, only the first edge 411 of the pixel opening 41 can be aligned away from the fourth edge 1111 of the second conductive trace 111. This makes it easier to adjust the relative position between the second conductive trace 111 and the pixel opening 41 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0136] Preferably, the second edge 61 and the fourth edge 1111 are staggered.

[0137] When the display panel is bent, the fourth edge 1111 of the second conductive trace 111 exerts greater stress on the film layer of the light-emitting functional portion 52 located at the second edge 61. In this embodiment, only the second edge 61 can be offset from the fourth edge 1111. That is, when manufacturing the display panel, only the second edge 61 of the support pillar 6 can be aligned away from the fourth edge 1111 of the second conductive trace 111. This makes it easier to adjust the relative position between the second conductive trace 111 and the support pillar 6 while preventing the film layer of the light-emitting functional portion 52 from separating.

[0138] In some possible implementations, a minimum distance W2 between the first edge 411 and the fourth edge 1111 is greater than or equal to 0.5 μm and less than or equal to 10 μm.

[0139] For example, the minimum distance W2 can be 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, or 10 μm. If the minimum distance W2 is set too small, the fourth edge 1111 may affect the film layer of the light-emitting functional portion 52 located at the first edge 411, increasing the risk of the film layer of the light-emitting functional portion 52 separating at the first edge 411. If the minimum distance W2 is set too large, it will increase the difficulty in designing the relative position between the second conductive trace 111 and the pixel opening 41. Therefore, a reasonable setting of the minimum distance W2 can prevent the film layer of the light-emitting functional portion 52 from separating at the first edge 411 and make it easier to design the relative position between the second conductive trace 111 and the pixel opening 41.

[0140] Preferably, the minimum distance D2 between the second edge 61 and the fourth edge 1111 is greater than or equal to 0.5 μm and less than or equal to 10 μm.

[0141] For example, the minimum distance D2 can be 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, or 10 μm. If the minimum distance D2 is set too small, the fourth edge 1111 may affect the film layer of the light-emitting functional portion 52 located at the second edge 61, increasing the risk of the film layer of the light-emitting functional portion 52 separating at the second edge 61. If the minimum distance D2 is set too large, it will increase the difficulty in designing the relative position between the second conductive trace 111 and the support pillar 6. Therefore, a reasonable setting of the minimum distance D2 can prevent the film layer of the light-emitting functional portion 52 from separating at the second edge 61 and make it easier to design the relative position between the second conductive trace 111 and the support pillar 6.

[0142] In summary, the third edge 31 of the first conductive trace 3 in the fourth conductive sublayer 12 applies greater stress to the light-emitting functional portion 52 located at the first edge 411 of the pixel opening 41 and the second edge 61 of the support column 6, and the fourth edge 1111 of the second conductive trace 111 in the third conductive sublayer 11 applies relatively greater stress to the light-emitting functional portion 52 located at the first edge 411 of the pixel opening 41 and the second edge 61 of the support column 6. In the present application, only the first edge 411, the second edge 61, and the third edge 31 may be staggered, and the first edge 411, the second edge 61, and the fourth edge 1111 may be staggered. In this way, while the film layer of the light-emitting functional portion 52 is not easily separated, thereby improving the display effect of the display panel, the relative positions of the first conductive trace 3, the second conductive trace 111, the pixel opening 41, and the support column 6 can be greatly reduced, thereby reducing the difficulty of manufacturing the display panel.

[0143] It is worth noting that the conductive traces in all the drawings of this application (e.g., the first conductive trace 3 and the second conductive trace 111) are only exemplary and do not represent the actual shape and direction of the corresponding conductive traces. They are only for illustrating that the edges of the corresponding conductive traces and the edges of the pixel opening 41 and the support column 6 have the above-mentioned solution of this application. Figure 7 、 Figure 9 and Figure 10 The conductive traces in the diagram correspond to the specific application scenarios of the folding screen. Therefore, Figure 7 、 Figure 9 and Figure 10 The conductive traces shown in FIG are parallel to the bending axis 8 .

[0144] For some possible implementations, see again Figure 3 and Figure 4The present application also provides a display panel, which includes a substrate 1, a conductive layer 2, a pixel defining layer 4, a light-emitting unit 5 and a support column 6.

[0145] The conductive layer 2 is located on one side of the substrate 1 and includes a first conductive trace 3 . The pixel defining layer 4 is located on a side of the conductive layer 2 away from the substrate 1 and includes a pixel opening 41 .

[0146] At least part of the light emitting unit 5 is located in the pixel opening 41 ; it is located on the side of the pixel defining layer 4 away from the substrate 1 , and the edge of the orthographic projection of the support column 6 on the substrate 1 is staggered with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 .

[0147] After further research, the inventors found that the side of the light-emitting functional part 52 of the light-emitting unit 5 close to the edge of the support column 6 is uneven, and the stress of the light-emitting functional part 52 at the edge of the support column 6 is more concentrated, that is, the stress exerted on the light-emitting functional part 52 of the light-emitting unit 5 at the edge of the support column 6 is greater than the stress exerted on the light-emitting functional part 52 on the side of the pixel defining layer 4 away from the substrate 1.

[0148] In the related art, the edges of the positive projections of the first conductive trace 3 and the support column 6 on the substrate 1 at least partially overlap. When the display panel is bent, the edge of the first conductive trace 3 exerts greater stress on the light-emitting functional part 52 located at the edge of the support column 6, making it easier for the film layers in the light-emitting functional part 52 of the light-emitting unit 5 to separate from each other at the edge of the support column 6.

[0149] If the orthographic projection of the support column 6 on the substrate 1 is set to be staggered with the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the orthographic projection of the support column 6 on the substrate 1 and the orthographic projection of the first conductive trace 3 on the substrate 1 do not overlap, then as the pixel density of the screen becomes higher and higher, the first conductive trace 3 will become more and more dense, making it difficult to set the orthographic projection of the support column 6 on the substrate 1 to be staggered with the orthographic projection of the first conductive trace 3 on the substrate 1.

[0150] In this embodiment, the edge of the orthographic projection of the support column 6 on the substrate 1 is set to be staggered with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the edge of the orthographic projection of the support column 6 on the substrate 1 does not overlap with the edge of the orthographic projection of the first conductive trace 3 on the substrate 1, that is, the edge of the orthographic projection of the support column 6 on the substrate 1 and the edge of the orthographic projection of the first conductive trace 3 on the substrate 1 are arranged at intervals.

[0151] In this way, when the display panel is bent, the stress generated by the edge of the first conductive trace 3 is not easily directly applied to the film layer of the light-emitting functional part 52 at the edge of the support column 6, thereby reducing the stress on the film layer of the light-emitting functional part 52 located at the edge of the support column 6, making it difficult for the film layers of the light-emitting functional part 52 to separate from each other at the edge of the pixel opening 41, and further making it difficult for the corresponding light-emitting unit 5 to produce black spots, which can ultimately improve the display effect of the display panel.

[0152] In addition, this embodiment does not completely avoid the first conductive trace 3 from the support column 6, that is, the orthographic projections of the first conductive trace 3 and the support column 6 on the substrate 1 can be allowed to at least partially overlap. It is only necessary to avoid the edges of the orthographic projection of the support column 6 on the substrate 1 and the edges of the orthographic projection of the first conductive trace 3 on the substrate 1. This can increase the space for setting the support column 6, reduce the difficulty of setting the relative positions of the first conductive trace 3 and the support column 6, and improve the feasibility of the solution.

[0153] The remaining technical solutions of the display panel in this embodiment are the same as those of the display panel in the above embodiment and will not be described again here.

[0154] In some possible implementations, the present application further provides an electronic device including the display panel described herein. The electronic device may include a device with image processing capabilities, such as a server, a personal computer, a laptop computer, a mobile phone, a tablet computer, a wearable device, or an in-vehicle display device. Because the electronic device includes the display panel described herein, the display quality of the electronic device is improved.

[0155] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0156] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
