Description

Technical Field

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

[0002] Compared to LCD technology, OLED (Organic Light-Emitting Diode) display technology boasts numerous advantages, including high contrast, wide color gamut, low power consumption, thinner and lighter structures, and flexibility. Currently, OLED display technology is widely used in mobile phones, computers, televisions, and other fields. In traditional display panel manufacturing, a fine metal mask (FMM) is typically used to pattern the light-emitting pixels. FMM technology is mature and has extensive mass production experience. However, FMM technology also suffers from limitations in precision, high development costs, and long development cycles. Fine metal maskless technology eliminates the limitations of traditional OLED processes on display size, resolution, and other screen performance aspects, offering advantages such as high performance, full-size display, and agile delivery.

[0089] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0090] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly or indirectly fixed to or set on that other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the purpose of description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this patent. The terms "first" and "second" are used only for the purpose of description and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly specified.

[0091] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0092] Please see Figure 1 As shown, this application embodiment first provides a display panel 100, which includes a substrate 1 and a plurality of pixel groups disposed on one side of the substrate 1. Each pixel group includes a plurality of light-emitting devices 3 of different colors, and in each pixel group, the number of light-emitting devices 3 of each color is at least one.

[0093] Please refer to the following: Figure 1 and Figure 2 As shown, the display panel 100 also includes an isolation structure 2 disposed on one side of the substrate 1. The isolation structure 2 defines a plurality of spaced-apart isolation openings 20, and at least a portion of each light-emitting device 3 is disposed within the isolation opening 20. Please refer to [reference needed]. Figure 2 and Figure 9As shown, the encapsulation structure 4 includes a first encapsulation layer 41, which includes a plurality of encapsulation parts 411, each of which is provided with a light-emitting device 3 and an isolation opening 20.

[0094] Specifically, please refer to Figure 2 As shown, each encapsulation portion 411 includes an encapsulation body portion 412 located within the isolation opening 20 and on the side of the light-emitting device 3 facing away from the substrate 1, and an encapsulation edge portion 413 located on the side of the isolation structure 2 facing away from the substrate 1. Of course, the encapsulation body portion 412 and the encapsulation edge portion 413 of each encapsulation portion 411 are connected to each other on the side of the isolation structure 2, so that the encapsulation portion 411 is a continuously arranged encapsulation layer, thereby encapsulating and protecting the light-emitting device 3 within the isolation opening 20.

[0095] Each film layer structure of the light-emitting device 3 and the first encapsulation layer 41 are fabricated through an etching process, which includes at least one of wet etching and dry etching processes. During the etching process of each light-emitting device 3 and its corresponding encapsulation portion 411, the encapsulation edge portion 413 located on the side of the isolation structure 2 facing away from the substrate 1 is prone to warping and deformation. This reduces the connection force between the encapsulation portion 411 and the side of the isolation structure 2, affecting the reliability of the connection between the encapsulation portion 411 and the side of the isolation structure 2. Furthermore, the light-emitting devices 3 of different colors and their corresponding encapsulation portions 411 have a sequential etching order. Therefore, for the light-emitting device 3 and its corresponding encapsulation portion 411 fabricated earlier, after one or more subsequent etching processes, the degree of warping and deformation of the encapsulation edge portion 413 will be further aggravated.

[0096] If the encapsulation part 411 peels off from the side of the isolation structure 2, a moisture intrusion path is formed towards the light-emitting device 3. This can easily lead to the failure of the light-emitting device 3 and the generation of dark spots in the display.

[0097] Based on this, this application provides a display panel 100, which aims to reduce or even avoid deformation of the packaging edge portion 413 of the packaging portion 411, ensure the connection reliability between the packaging portion 411 and the side of the isolation structure 2, and thereby improve the packaging reliability of the light-emitting device 3.

[0098] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, for each pixel group, the orthographic projections of at least two adjacent package edges 413 on the substrate 1 are either spaced apart or adjacent; in other words, the orthographic projections of at least two adjacent package edges 413 on the surface of the isolation structure 2 facing away from the substrate 1 are non-overlapping. In each pixel group, the orthographic projections of at least two adjacent package edges 413 on the substrate 1 are spaced apart (e.g., ...). Figure 3(as shown), or they meet at points that are close to each other (as shown). Figure 4 (As shown).

[0099] like Figure 3 and Figure 4 As shown, in each pixel group, the distance between the orthographic projections of at least two adjacent encapsulation edges 413 on the side of the isolation structure 2 facing away from the substrate 1 is H, then H≥0.

[0100] In this embodiment, within the length range of the surface of the isolation structure 2 facing away from the substrate 1, the orthographic projections of two adjacent package edges 413 on the surface of the isolation structure 2 facing away from the substrate 1 are spaced apart or connected. This helps to reduce the degree of deformation of the package edges 413 in its own etching process and subsequent processes. In turn, it helps to reduce the peeling tendency between the package portion 411 and the side of the isolation structure 2, ensure the packaging reliability of the light-emitting device 3, and reduce or even avoid display dark spots.

[0101] Please see Figure 2 As shown, the light-emitting device 3 includes a first electrode 31, a light-emitting functional layer 32, and a second electrode 33 stacked sequentially. The first electrode 31 is disposed on one side of the substrate 1, and the light-emitting functional layer 32 and the second electrode 33 are stacked sequentially on the side away from the substrate 1. The encapsulation portion 411 is disposed on the side of the second electrode 33 away from the substrate 1.

[0102] The first electrode 31 can be an anode, and the second electrode 33 can be a cathode. Depending on the specific material of the light-emitting functional layer 32, the light-emitting device 3 can emit different colors.

[0103] Please continue reading. Figure 2 As shown, the display panel 100 also includes a pixel definition layer 11, which has a plurality of pixel openings 10. An isolation structure 2 is disposed on one side of the pixel definition layer 11, and the pixel openings 10 and the isolation openings 20 are connected in the thickness direction of the substrate 1. Please refer to [reference needed]. Figure 1 and Figure 2 As shown.

[0104] In one embodiment, the first electrode 31 is located on the side of the pixel definition layer 11 closest to the substrate 1, and a portion of the first electrode 31 is exposed within the pixel opening 10. Alternatively, the pixel definition layer 11 is located on the side of the first electrode 31 facing the second electrode 33 and exposes a portion of the first electrode 31. The edge of the light-emitting functional layer 32 is located on the side of the pixel definition layer 11 opposite to the substrate 1.

[0105] In addition, the substrate 1 includes multiple wiring layers and multiple insulating layers (not shown), with the insulating layers disposed between adjacent wiring layers. The multiple wiring layers constitute a pixel driving circuit and are connected to the first electrode 31 and the second electrode 33 to provide the voltage required for light emission to the light-emitting device 3.

[0106] Specifically, please refer to Figure 2 As shown, the isolation structure 2 includes a first isolation portion 21 and a second isolation portion 22. The first isolation portion 21 is disposed on one side of the substrate 1, and the second isolation portion 22 is disposed on the side of the first isolation portion 21 facing away from the substrate 1. The orthographic projection of the first isolation portion 21 on the substrate 1 lies within the orthographic projection of the second isolation portion 22 on the substrate 1. Optionally, the edge of the orthographic projection of the first isolation portion 21 on the substrate 1 is spaced apart from the edge of the orthographic projection of the second isolation portion 22 on the substrate 1. With this isolation structure 2, adjacent light-emitting devices 3 and packaging portions 411 can be separated during the manufacturing process of the light-emitting device 3 and the packaging portion 411. Please refer to the reference. Figure 1 and Figure 2 As shown, Figure 1 From a top-down view, the isolation opening 20 is shown in the area defined by the edge of the second isolation section 22.

[0107] In one embodiment, at least the first isolation portion 21 comprises a metallic material. The second electrode 33 of each light-emitting device 3 overlaps with the side of the first isolation portion 21. Thus, electrical connection is achieved between each second electrode 33 and the first isolation portion 21, and each second electrode 33 has a common potential.

[0108] Optionally, the material of the first isolation section 21 may include aluminum or copper.

[0109] In one embodiment, the second isolation portion 22 may include a metallic material. Optionally, the material of the second isolation portion 22 may include titanium or molybdenum.

[0110] In one embodiment, the isolation structure 2 may further include a third isolation portion (not shown), which is disposed on one side of the substrate 1, and the first isolation portion 21 is disposed on the side of the third isolation portion opposite to the substrate 1. The third isolation portion is mainly used to connect the first isolation portion 21 to the substrate 1. Optionally, the orthographic projection of the first isolation portion 21 on the substrate 1 is located within the orthographic projection of the third isolation portion on the substrate 1. Further optionally, the edge of the orthographic projection of the first isolation portion 21 on the substrate 1 is spaced apart from the edge of the orthographic projection of the third isolation portion on the substrate 1.

[0111] In one embodiment, the third isolation portion may include a metallic material. Optionally, the material of the third isolation portion may include molybdenum or titanium.

[0112] Please see Figure 2As shown, the package portion 411 is in contact with the side of the second isolation portion 22. A gap 27 is formed between the package edge portion 413 and the side surface of the second isolation portion 22 facing away from the substrate 1.

[0113] The material of the first encapsulation layer 41 may include inorganic materials.

[0114] Please refer to the following: Figure 9 As shown, in one embodiment, the encapsulation structure 4 further includes a second encapsulation layer 42. The material of the second encapsulation layer 42 may include an organic encapsulation material. The second encapsulation layer 42 is disposed on the side of the first encapsulation layer 41 facing away from the substrate 1 to enclose and protect the first encapsulation layer 41. The second encapsulation layer 42 may be fabricated using a self-leveling method such as inkjet printing. Figure 9 As shown, at least a portion of the second encapsulation layer 42 fills the gap 27 between the encapsulation edge portion 413 and the side surface of the second isolation portion 22 facing away from the substrate 1.

[0115] Please continue reading. Figure 9 As shown, in one embodiment, the encapsulation structure 4 further includes a third encapsulation layer 43. The material of the third encapsulation layer 43 may include inorganic materials. The third encapsulation layer 43 is disposed on the side of the second encapsulation layer 42 facing away from the substrate 1, and is used to further encapsulate the second encapsulation layer 42 and the first encapsulation layer 41 within it.

[0116] It should be noted that the encapsulation edge portion 413 of each encapsulation portion 411 is arranged continuously around its encapsulation body portion 412. From the cross-sectional view of the display panel 100, as shown... Figure 2 As shown, the isolation structure 2 has encapsulation edge portions 413 with different encapsulation portions 411 on both sides, and each encapsulation portion 411 has encapsulation edge portions 413 corresponding to the isolation structure 2 on both sides. The "at least two adjacent encapsulation edge portions 413" mentioned above refers to two encapsulation edge portions 413 on the side that are close to each other of at least two adjacent encapsulation portions 411.

[0117] In one embodiment, in each pixel group, at least two adjacent package edge portions 413 have their orthographic projections on the substrate 1 spaced apart. That is, the distance H between the orthographic projections of at least two adjacent package edge portions 413 on the substrate 1 is greater than 0. Figure 2 As shown.

[0118] In one alternative embodiment, the distance H between the orthographic projections of at least two adjacent package edges 413 onto the substrate 1 is greater than or equal to 2 micrometers.

[0119] In one alternative embodiment, the distance H between the orthographic projections of at least two adjacent package edges 413 onto the substrate 1 is greater than or equal to 4 micrometers.

[0120] In one alternative embodiment, the distance H between the orthographic projections of at least two adjacent package edges 413 onto the substrate 1 is greater than or equal to 6 micrometers.

[0121] The purpose of this arrangement is twofold. First, for the first package portion 411 formed later, before etching, the film layer will completely cover the package edge portion 413 formed earlier. The edge of the film layer corresponding to the package edge portion 413 will form a bending step. There is a distance H between the orthographic projections of two adjacent package edge portions 413 on the substrate 1, so that the package edge portion 413 formed later can avoid the step of the film layer as much as possible, ensuring that the thickness of the package edge portion 413 formed later is consistent and relatively flat, which is beneficial to reducing the warping tendency in the etching process. Second, the distance H between the orthographic projections of two adjacent package edge portions 413 on the substrate 1 can make each package edge portion 413 have a length range that avoids causing warping deformation.

[0122] Based on the etching process of the light-emitting device 3 and its corresponding packaging portion 411, the length L of each packaging edge portion 413 is less than or equal to the length D of the end of the isolation structure 2 facing away from the substrate 1. Please refer to [link to relevant documentation]. Figure 1 , Figure 3 and Figure 4 As shown. That is, the packaging edge 413 of each packaging portion 411 does not extend into an adjacent isolation opening 20.

[0123] It should be noted that: 1. In this application, the encapsulation edge portion 413 and the isolation structure 2 for length comparison refer to the encapsulation edge portion 413 and the isolation structure 2 corresponding in the thickness direction of the substrate 1; 2. The length direction is perpendicular to the thickness direction of the substrate 1 and parallel to the side surface of the substrate 1 where the light-emitting device 3 is located; 3. On the side surface of the substrate 1 where the light-emitting device 3 is located, the length direction is not a uniquely determined direction. However, when comparing the lengths of the encapsulation edge portion 413 and the isolation structure 2, they should be based on the same length direction. For example, when the isolation opening 20 is rectangular, the length direction can refer to the direction along the long side of the rectangle or the direction along the short side of the rectangle. When the isolation opening 20 is circular, the length direction can refer to the radial direction. For isolation openings 20 of other shapes, the length direction can be determined based on a suitable position. Different positions of the isolation structure 2 may have different lengths D.

[0124] When the length D of the end of the isolation structure 2 away from the substrate 1 is small in a certain direction, the length L of the two packaging edge portions 413 on the side of the isolation structure 2 away from the substrate 1 can be small. In this case, the risk of deformation of the two packaging edge portions 413 is low.

[0125] When the length D of the end of the isolation structure 2 away from the substrate 1 is large in a certain direction, the length L of the two packaging edge portions 413 on the side of the isolation structure 2 away from the substrate 1 should be appropriately reduced so that the orthographic projections of the two adjacent packaging edge portions 413 on the side of the isolation structure 2 away from the substrate 1 do not overlap (meaning they are spaced apart or their edges are just touching), so as to reduce the risk of deformation of the two packaging edge portions 413.

[0126] Based on the above, the length D of the isolation structure 2 may vary at different locations, and the area of ​​the isolation opening 20 or the pixel opening 10 may also vary. Based on process requirements and to ensure the packaging reliability of each packaging section 411, the length L of the packaging edge 413 of each packaging section 411 is greater than or equal to 2 micrometers.

[0127] The purpose of this setting is to provide further information. Figure 2 As shown, if the length L of the packaging edge portion 413 of the packaging portion 411 is small, the length of the gap 27 will also be small in its own etching process and subsequent etching processes, especially in the wet etching process. The etching solution can easily invade through the gap 27 between the adjacent surfaces of the packaging edge portion 413 and the second isolation portion 22. For example, excessive invasion between the sides of the packaging portion 411 and the second isolation portion 22 can cause the packaging portion 411 to peel off. Therefore, having an appropriate length for the packaging edge portion 413 can reduce and mitigate unnecessary invasion of the etching solution.

[0128] In one alternative embodiment, the length L of the packaging edge portion 413 of each packaging portion 411 is greater than or equal to 3 micrometers.

[0129] In one alternative embodiment, the length L of the packaging edge portion 413 of each packaging portion 411 is greater than or equal to 4 micrometers.

[0130] In one optional embodiment, the distance H between the orthographic projections of two adjacent package edges 413 on the substrate 1 is less than or equal to the length L of either of the two package edges 413. This is to ensure that the length L of the package edge 413 of each package portion 411 is maintained by limiting the distance H between the orthographic projections of two adjacent package edges 413 on the substrate 1. The orthographic projections of two adjacent package edges 413 on the substrate 1 do not need to be excessively spaced.

[0131] In an optional embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 8 micrometers to 24 micrometers.

[0132] For example, in some locations or orientations, the length D of the end of the isolation structure 2 away from the substrate 1 is 8 micrometers to 20 micrometers, further such as 12 micrometers to 19 micrometers, and even further such as 14 micrometers to 18 micrometers; in other locations or orientations, the length D of the end of the isolation structure 2 away from the substrate 1 is 10 micrometers to 24 micrometers, further such as 14 micrometers to 24 micrometers, and even further such as 18 micrometers to 24 micrometers.

[0133] In an optional embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 10 micrometers to 24 micrometers.

[0134] In an optional embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 14 micrometers to 24 micrometers.

[0135] In an optional embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 10 micrometers to 23 micrometers.

[0136] In an optional embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 14 micrometers to 23 micrometers.

[0137] In an optional embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 16 micrometers to 23 micrometers.

[0138] In an optional embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 18 micrometers to 24 micrometers.

[0139] In one specific embodiment, the length D of the end of the isolation structure 2 facing away from the substrate 1 in any direction is 8 micrometers, 9 micrometers, 10 micrometers, 11 micrometers, 12 micrometers, 13 micrometers, 14 micrometers, 15 micrometers, 16 micrometers, 17 micrometers, 18 micrometers, 19 micrometers, 20 micrometers, 21 micrometers, 21.5 micrometers, 22 micrometers, 23 micrometers, 24 micrometers, etc.

[0140] In one optional embodiment, the distance H between the orthographic projections of at least two adjacent package edges 413 on the substrate 1 is 0 micrometers, 0.5 micrometers, 1 micrometer, 1.5 micrometers, 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, 6 micrometers, 6.5 micrometers, 7 micrometers, 7.5 micrometers, 8 micrometers, 8.5 micrometers, 9 micrometers, 9.5 micrometers, and 10 micrometers.

[0141] In one optional embodiment, the length L of the packaging edge portion 413 of each packaging portion 411 is 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, 6 micrometers, 6.5 micrometers, 7 micrometers, 7.5 micrometers, 8 micrometers, 8.5 micrometers, 9 micrometers, 9.5 micrometers, 10 micrometers, etc.

[0142] In one alternative embodiment, the difference in length L between two adjacent package edges 413 is less than or equal to 3 micrometers. In other words, the length L of the package edges 413 between different package portions 411 can be substantially similar, so that each package edge 413 has a suitable range of length L.

[0143] Further optionally, the difference in length L between two adjacent package edges 413 is less than or equal to 2 micrometers.

[0144] In some specific embodiments, the difference in length L between two adjacent package edges 413 is less than or equal to 3 micrometers, 2.5 micrometers, 2 micrometers, 1.5 micrometers, 1.5 micrometers, 1 micrometer, 0.5 micrometers, etc.

[0145] The purpose of this design is that each package edge 413 has a suitable length L range, which reduces the risk of warping during etching. On the other hand, since the lengths of each package edge 413 are similar, their ability to withstand water pressure and wind pressure during etching is roughly the same or similar. Therefore, the manufacturing processes of the package parts 411 corresponding to different colored light-emitting devices 3 can be roughly the same or similar. In other words, the applicability of the same or similar etching processes is wider, which provides convenience for the etching process.

[0146] In some specific embodiments, the length L of two adjacent package edges 413 is equal.

[0147] Please refer to the following: Figure 1 , Figures 6 to 8 As shown, depending on the arrangement of the light-emitting devices 3 in the pixel group, the position of the encapsulation edge portion 413 on the isolation structure 2 is different. In the display panel 100, the isolation opening 20 and the light-emitting devices 3 are arranged in a two-dimensional array. In different directions, the length D of the end of the isolation structure 2 away from the substrate 1 may be the same or different, and the length L of the encapsulation edge portion 413 in different directions may be the same or different.

[0148] Please see Figure 1 , Figure 6 and Figure 7 As shown, the isolation opening 20 is arranged on one side surface of the substrate 1 along a first direction X and a second direction Y that are perpendicular to each other. The length D1 of the end of the isolation structure 2 facing away from the substrate 1 in the first direction X is greater than the length D2 in the second direction Y. In particular, at least in the first direction X, the orthographic projections of two adjacent package edges 413 on the substrate 1 are spaced apart or connected.

[0149] Thus, since the adjacent isolation openings 20 are further apart in the first direction X, and the length D of the end of the isolation structure 2 away from the substrate 1 in the first direction X is greater, the orthographic projections of two adjacent package edges 413 on the substrate 1 in the first direction X must not overlap.

[0150] In one optional embodiment, if the length D of the end of the isolation structure 2 facing away from the substrate 1 in the first direction X is greater than or equal to 16 micrometers, then the orthographic projections of two adjacent package edges 413 on the substrate 1 in the first direction X must not overlap.

[0151] Optionally, in the second direction Y, the orthographic projections of two adjacent package edges 413 onto the substrate 1 are spaced apart, connected, or at least partially overlapping. Please refer to [reference needed]. Figure 1 and Figure 5 As shown. In an optional embodiment, the length D2 of the end of the isolation structure 2 facing away from the substrate 1 in the second direction Y is less than or equal to 16 micrometers. Then, in the second direction Y, the orthographic projections of two adjacent package edges 413 on the substrate 1 are spaced apart, connected, or at least partially overlapping.

[0152] Alternatively, in the second direction Y, the orthographic projections of two adjacent package edges 413 onto the substrate 1 are spaced apart or connected.

[0153] Alternatively, in the second direction Y, the orthographic projections of two adjacent package edges 413 onto the substrate 1 partially overlap, and the overlap length is less than or equal to 4 micrometers.

[0154] Optionally, in the second direction Y, the orthographic projections of two adjacent package edges 413 on the substrate 1 partially overlap, and the overlap length is less than or equal to 3 micrometers.

[0155] Please see Figure 1 As shown, in each pixel group, there is one light-emitting device 3 of a different color, and in each pixel group, multiple light-emitting devices 3 of different colors are arranged sequentially along the second direction Y. In this way, three light-emitting devices 3 are arranged in a row (the row direction is the second direction Y). In the first direction X, light-emitting devices 3 of the same color in two adjacent pixel groups can be aligned, or light-emitting devices 3 of different colors in two adjacent pixel groups can be aligned.

[0156] Optionally, in this embodiment, a rectangular array arrangement adapted to the pixel group is used, and each light-emitting device 3 and isolation opening 20 can also be rectangular (meaning generally rectangular). The lengths of each light-emitting device 3 and isolation opening 20 in the first direction X and the second direction Y are different. For example, the length of each light-emitting device 3 and isolation opening 20 in the first direction X is greater than the length in the second direction Y, so that the lengths of each pixel group in the first direction X and the second direction Y will not differ too much.

[0157] Please see Figure 6 As shown, each pixel group includes a first light-emitting device 30a, two second light-emitting devices 30b, and a third light-emitting device 30c. The two second light-emitting devices 30b are arranged along a first direction X, the first light-emitting devices 30a and the third light-emitting devices 30c are arranged along the first direction X, the second light-emitting devices 30b and the first light-emitting device 30a are arranged along a second direction Y, and the second light-emitting devices 30b and the third light-emitting devices 30c are arranged along the second direction Y. In this way, the four light-emitting devices 3 are arranged in two rows and two columns (the row direction is the second direction Y, and the column direction is the first direction X).

[0158] The colors corresponding to the first light-emitting device 30a, the second light-emitting device 30b, and the third light-emitting device 30c are not limited.

[0159] In this embodiment, along the first direction X, the orthographic projection of the encapsulation edge portion 413 between two adjacent second light-emitting devices 30b on the substrate 1 is non-overlapping, and / or, the orthographic projection of the encapsulation edge portion 413 between adjacent first light-emitting devices 30a and third light-emitting devices 30c on the substrate 1 is non-overlapping.

[0160] Along the second direction Y, the orthographic projections of the encapsulation edge portion 413 between the second light-emitting device 30b and the first light-emitting device 30a onto the substrate 1 may overlap, connect, or be spaced apart, and the orthographic projections of the encapsulation edge portion 413 between the second light-emitting device 30b and the third light-emitting device 30c onto the substrate 1 may overlap, connect, or be spaced apart.

[0161] In one optional embodiment, the length D1 of the isolation structure 2 in the first direction X is 10 micrometers to 24 micrometers, the length D2 of the isolation structure 2 in the second direction Y is 8 micrometers to 20 micrometers, and the length D1 of the isolation structure 2 in the first direction X is greater than the length D2 of the isolation structure 2 in the second direction Y.

[0162] In one optional embodiment, the length D1 of the isolation structure 2 in the first direction X is 16 micrometers to 24 micrometers, and the length D2 of the isolation structure 2 in the second direction Y is 12 micrometers to 18 micrometers.

[0163] In one optional embodiment, the length D1 of the isolation structure 2 in the first direction X is 16 micrometers, 17 micrometers, 18 micrometers, 19 micrometers, 20 micrometers, 21 micrometers, 21 micrometers, 22 micrometers, 23 micrometers, 24 micrometers, etc., and the length D2 of the isolation structure 2 in the second direction Y is 12 micrometers, 13 micrometers, 14 micrometers, 15 micrometers, 16 micrometers, 17 micrometers, 18 micrometers, etc., and the length D1 of the isolation structure 2 in the first direction X is greater than the length D2 of the isolation structure 2 in the second direction Y.

[0164] Please see Figure 7 As shown, each pixel group includes a first light-emitting device 30a, two second light-emitting devices 30b, and a third light-emitting device 30c. The first light-emitting device 30a and the two second light-emitting devices 30b are arranged along a first direction X, and the third light-emitting device 30c is arranged along a second direction Y on one side of the first light-emitting device 30a and the two light-emitting devices 30b.

[0165] Wherein, along the first direction X, at least the length D1 of the isolation structure 2 between the two third light-emitting devices 30c is greater than the length D2 of the isolation structure 2 between the third light-emitting device 30c and the second light-emitting device 30b along the second reverse direction Y, then, along the first direction X, the distance H between the orthogonal projections of two adjacent package edges 413 on the substrate 1 is greater than or equal to 0.

[0166] like Figure 8 As shown, in this embodiment, each first light-emitting device 30a is surrounded by a plurality of second light-emitting devices 30b, each second light-emitting device 30b is surrounded by a plurality of third light-emitting devices 30c and first light-emitting devices 30a alternately, and each third light-emitting device 30c is surrounded by a plurality of second light-emitting devices 30b.

[0167] Thus, there is an isolation structure 2 between adjacent first light-emitting devices 30a and third light-emitting devices 30c, an isolation structure 2 between adjacent first light-emitting devices 30a and second light-emitting devices 30b, an isolation structure 2 between adjacent second light-emitting devices 30b and third light-emitting devices 30c, and an isolation structure 2 between two adjacent second light-emitting devices 30b.

[0168] In one alternative embodiment, such as Figure 8 As shown, each first light-emitting device 30a is surrounded by four second light-emitting devices 30b, each second light-emitting device 30b is surrounded by two third light-emitting devices 30c and two first light-emitting devices 30a alternately, and each third light-emitting device 30c is surrounded by four second light-emitting devices 30b.

[0169] In one alternative embodiment, such as Figure 8As shown, along the first direction X, the first light-emitting device 30a and the third light-emitting device 30c are arranged alternately in sequence, and along the second direction Y, the first light-emitting device 30a and the third light-emitting device 30c are arranged alternately in sequence. Along the third direction Z, the second light-emitting device 30b is located between adjacent first light-emitting devices 30a and adjacent third light-emitting devices 30c, wherein the third direction Z is parallel to one surface of the substrate 1 and forms an angle with both the first direction X and the third direction Z, such as 45°. Furthermore, a plurality of second light-emitting devices 30b are arranged along the first direction X and the second direction Y.

[0170] Optionally, in the first direction X, on the isolation structure 2 between the first light-emitting device 30a and the third light-emitting device 30c, the orthographic projections of two adjacent package edges 413 on the substrate 1 are spaced apart or connected; and / or, in the first direction X, on the isolation structure 2 between two adjacent second light-emitting devices 30b, the orthographic projections of two adjacent package edges 413 on the substrate 1 are spaced apart or connected. Specific values ​​can be referred to in the foregoing embodiments, and will not be elaborated further.

[0171] Alternatively, in the second direction Y, on the isolation structure 2 between the first light-emitting device 30a and the third light-emitting device 30c, the orthographic projections of two adjacent package edges 413 on the substrate 1 are either spaced apart or connected. Specific values ​​can be found in the foregoing embodiments, and will not be elaborated further.

[0172] On the third-party side, on the isolation structure 2 between adjacent second light-emitting devices 30b, the orthographic projections of two adjacent package edges 413 on the substrate 1 are spaced apart, connected, or partially overlapping. Specific values ​​can be referred to in the foregoing embodiments, and will not be elaborated further.

[0173] In other embodiments, the multiple light-emitting devices 3 in the pixel group can be arranged in other ways. Generally, depending on the length of the isolation structure 2 at different locations, on the side of the longer isolation structure 2 facing away from the substrate 1, two adjacent encapsulation edges 413 are arranged to be spaced apart or intersecting.

[0174] Please see Figure 10 As shown, in one embodiment, this application provides a display panel 100, wherein in each pixel group, the length L of the orthographic projection of at least two adjacent encapsulation edge portions 413 on the substrate 1 is less than or equal to two-thirds of the length of the end of the isolation structure 2 away from the substrate 1.

[0175] In this embodiment, the length L of the orthographic projection of at least two adjacent package edges 413 onto the substrate 1 is less than or equal to two-thirds of the length D of the end of the isolation structure 2 facing away from the substrate 1. The length of either of the two adjacent package edges 413 is not too large, and the overlap length h of the orthographic projection of the two adjacent package edges 413 onto the substrate 1 does not exceed one-third of the length of the end of the isolation structure 2 facing away from the substrate 1. That is, the overlap length h can also be small. This helps to reduce the degree of deformation of the package edges 413 in its own etching process and subsequent etching processes, thereby helping to reduce the peeling tendency between the package portion 411 and the side of the isolation structure 2, ensuring the packaging reliability of the light-emitting device 3, and reducing or even avoiding display dark spots.

[0176] In this embodiment, on the side of the isolation structure 2 away from the substrate 1, the two corresponding packaging edges 413 are allowed to overlap, but the overlap length h is limited.

[0177] Optionally, in one embodiment, the lengths of the orthographic projections of at least two adjacent package edges 413 onto the substrate 1 are each less than or equal to 60% of the length D of the end of the isolation structure 2 facing away from the substrate 1. In this embodiment, on the side of the isolation structure 2 facing away from the substrate 1, the corresponding two package edges 413 are allowed to overlap, but the overlap length h does not exceed 20% of the length D of the end of the isolation structure 2 facing away from the substrate 1.

[0178] Alternatively, the lengths of the orthographic projections of at least two adjacent package edges 413 onto the substrate 1 are each less than or equal to half the length of the end of the isolation structure 2 facing away from the substrate 1. In this case, the two corresponding package edges 413 on the side of the isolation structure 2 facing away from the substrate 1 do not overlap.

[0179] In this embodiment, the range of the length L of each encapsulation edge 413 can be set with reference to the aforementioned embodiments, and will not be repeated here.

[0180] In this embodiment, the arrangement of the pixel group on the substrate 1, and the arrangement of the multiple light-emitting devices 3 in each pixel group, can be set with reference to the aforementioned embodiments.

[0181] Please see Figure 11 As shown, this application provides a display panel 100, in which the length L of the orthographic projection of at least two adjacent encapsulation edge portions 413 on the substrate 1 in each pixel group is less than or equal to 15 micrometers.

[0182] In this embodiment, for each pixel group, the length of the orthographic projection of at least two adjacent package edge portions 413 on the substrate 1 is less than or equal to 15 micrometers. The length of either of the two adjacent package edge portions 413 is not too large, which helps to reduce the degree of deformation of the package edge portion 413 in its own etching process and subsequent etching processes. In turn, it helps to reduce the peeling tendency between the package portion 411 and the side of the isolation structure 2, ensure the packaging reliability of the light-emitting device 3, and reduce or even avoid display dark spots.

[0183] In one embodiment, please refer to Figure 12 As shown, in each pixel group, at least two adjacent package edge portions 413 have their orthographic projections on the substrate 1 overlapping, and the overlap length h is less than or equal to half the length L of any one of the two adjacent package edge portions 413.

[0184] In one embodiment, for each pixel group, the length L of the orthographic projection of at least two adjacent package edge portions 413 on the substrate 1 is less than or equal to 10 micrometers, and the length L of the orthographic projection of at least two adjacent package edge portions 413 on the substrate 1 is greater than or equal to 2 micrometers.

[0185] In one embodiment, for each pixel group, the length L of the orthographic projection of at least two adjacent package edge portions 413 on the substrate 1 is less than or equal to 8 micrometers, and the length L of the orthographic projection of at least two adjacent package edge portions 413 on the substrate 1 is greater than or equal to 3 micrometers.

[0186] For example, in one specific embodiment, the length L of the orthographic projection of at least two adjacent package edges 413 on the substrate 1 in each pixel group is independently 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, 6 micrometers, 6.5 micrometers, 7 micrometers, 7.5 micrometers, 8 micrometers, 8.5 micrometers, 9 micrometers, 9.5 micrometers, 10 micrometers, etc.

[0187] In this embodiment, the arrangement of the pixel group on the substrate 1, and the arrangement of the multiple light-emitting devices 3 in each pixel group, can be set with reference to the aforementioned embodiments.

[0188] Finally, this application also provides a display device, which may include the display panel described in any of the above embodiments, and has the features and effects corresponding to the display panels in the above embodiments, which will not be repeated here.
