[0003] This application relates to the field of displays, specifically to a display panel and a display device. Background Technology

[0004] Organic light-emitting diodes (OLEDs) and flat panel displays based on light-emitting diode (LED) technologies are widely used in consumer electronics products such as mobile phones, televisions, laptops, and desktop computers due to their advantages such as high image quality, energy saving, thin body, and wide application range, becoming the mainstream display devices. In the traditional display panel manufacturing process, 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 has problems such as limited precision, high development costs, and long development cycles. Fine metal mask-less technology eliminates the limitations of traditional OLED processes on display size, resolution, and other screen performance characteristics, offering advantages such as high performance, full-size display, and agile delivery.

[0034] This application provides a display panel, a display device, and a method for manufacturing the display panel. The embodiments of the display panel, display device, and method for manufacturing the display panel will be described below with reference to the accompanying drawings.

[0035] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0036] Please refer to Figures 1 to 3 together. Figure 1 is a partial cross-sectional view of a display panel provided in an embodiment of this application; Figure 2 is a cross-sectional view of Figure 1 at point AA in one example; Figure 3 is a partially enlarged structural schematic diagram of Figure 2.

[0037] As shown in Figures 1 to 3, a first aspect of this application provides a display panel, which includes: a substrate 100, an isolation structure 200, a light-emitting layer 300, and a first encapsulation layer 400; the isolation structure 200 is located on one side of the substrate 100, and defines an isolation opening 210. The isolation structure 200 includes an isolation segment 220, which is disposed within at least one isolation opening 210 and divides the isolation opening 210 into at least two sub-openings 210a; the light-emitting layer 300 is located on one side of the substrate 100, and includes a plurality of light-emitting units 310, at least some of which are located within the isolation opening 210a. Within 0, at least one light-emitting unit 310 includes at least two sub-units 310a spaced apart, at least a portion of the sub-units 310a being located within a sub-opening 210a. The sub-units 310a include a first sub-electrode 301a, a light-emitting substructure 302a, and a second sub-electrode 303a stacked in a direction away from the substrate 100. The first encapsulation layer 400 includes an encapsulation portion 410 for encapsulating the light-emitting unit 310. The first sub-electrodes 301a of the plurality of sub-units 310a of the same light-emitting unit 310 are electrically connected to each other, and at least a portion of the isolation segment 220 is located within the orthogonal projection of the encapsulation portion 410 on the substrate 100.

[0038] According to an embodiment of this application, the display panel includes a substrate 100, an isolation structure 200, a light-emitting layer 300, and a first encapsulation layer 400. The isolation structure 200 defines an isolation opening 210, and an isolation segment 220 is provided within the isolation opening 210, which divides the isolation opening 210 into two or more sub-openings 210a. At least a portion of the light-emitting unit 310 of the light-emitting layer 300 is located within the isolation opening 210. The light-emitting unit 310 includes two or more sub-units 310a spaced apart, with at least a portion of each sub-unit 310a located within a sub-opening 210a. The isolation segment 220 is located between adjacent sub-units 310a. Each sub-unit 310a includes a first sub-electrode 301a, a light-emitting substructure 302a, and a second sub-electrode 303a, which drive the light-emitting substructure 302a to emit light. The encapsulation portion 410 of the first encapsulation layer 400 provides encapsulation protection to the light-emitting unit 310. Multiple first sub-electrodes 301a of the same light-emitting unit 310 are electrically connected to each other, so that multiple sub-units 310a of the same light-emitting unit 310 can be driven by the same pixel circuit 110, which simplifies the structure of the pixel circuit 110. At least a portion of the isolation segment 220 is located within the orthographic projection of the encapsulation portion 410 on the substrate 100, that is, the encapsulation portion 410 also covers the isolation segment 220 located between two adjacent sub-openings 210a, which can increase the distribution area of ​​the encapsulation portion 410, improve the encapsulation effect, and thus improve the yield and performance of the display panel.

[0039] Furthermore, in this embodiment, the same light-emitting unit 310 is divided into two or more sub-units 310a. When one sub-unit 310a malfunctions, the remaining sub-units 310a can still continue to emit light, thereby avoiding display defects caused by the same light-emitting unit 310 not lighting up at all, and improving the display effect of the display panel.

[0040] Optionally, the display panel further includes a pixel definition layer, which includes a pixel defining portion 320 and a pixel opening 330 formed by the pixel defining portion 320. The pixel opening 330 is connected to the isolation opening 210, and at least some of the light-emitting units 310 can be located within the pixel opening 330 within the isolation opening 210, so that the light-emitting units 310 can emit light through the isolation opening 210. Optionally, the isolation structure 200 can be located on the side of the pixel defining portion 320 away from the substrate 100, or the pixel defining portion 320 can be provided with a clearance opening, and the isolation structure 200 can be located within the clearance opening. Optionally, the pixel opening 330 includes a pixel sub-opening 330a corresponding to the sub-opening 210a, and the pixel sub-opening 330a is connected to the sub-opening 210a.

[0041] Optional. The light-emitting unit 310 includes a first electrode 301, a light-emitting structure 302, and a second electrode 303. When the light-emitting unit 310 includes multiple sub-units 310a, the first sub-electrodes 301a of the multiple sub-units 310a constitute the first electrode 301 of the light-emitting unit 310, the light-emitting sub-structures 302a of the multiple sub-units 310a constitute the light-emitting structure 302 of the light-emitting unit 310, and the second sub-electrodes 303a of the multiple sub-units 310a constitute the second electrode 303 of the light-emitting unit 310.

[0042] There are various ways to configure the isolation structure 200. The isolation structure 200 can be a single-layer film structure, and its cross-section can be an inverted trapezoid, that is, the cross-section of the isolation structure 200 gradually decreases along the direction close to the substrate 100, so as to form a concave side of the isolation structure 200 facing the isolation opening 210. The concave side is used to block the formation of independent light-emitting substructures 302a by the light-emitting material. In this case, the isolation opening 210 and the sub-opening 210a are defined by a single-layer film structure.

[0043] In some alternative embodiments, the isolation structure 200 includes a first sub-layer 201 and a second sub-layer 202 located on the side of the first sub-layer 201 facing away from the substrate 100. The first sub-layer 201 lies within the orthographic projection of the second sub-layer 202 onto the substrate 100. The second sub-layer 202 protrudes relative to the first sub-layer 201 toward the isolation opening 210, forming a recess on the side of the second sub-layer 202 toward the substrate 100. This recess is used to block the formation of mutually independent light-emitting substructures 302a by the light-emitting material. When the isolation structure 200 includes multiple film layers including the first sub-layer 201 and the second sub-layer 202, the multiple isolation openings 210 and sub-openings 210a are defined by the same film layer. For example, both the sub-openings 210a and the isolation openings 210 are defined by the second sub-layer 202, meaning that the orthographic projection of the edge of the second sub-layer 202 onto the substrate 100 completely coincides with the orthographic projection of the edge of the isolation opening 210 onto the substrate 100. In other embodiments, both the opening and the isolation opening 210 may be defined by the first sublayer 201.

[0044] Optionally, the isolation opening 210 and the light-emitting unit 310 are correspondingly arranged. The same isolation opening 210 corresponds to multiple sub-units 310a of the same light-emitting unit 310. The light-emitting sub-structures 302a of the multiple sub-units 310a of the same light-emitting unit 310 are located in the multiple sub-openings 210a of the same isolation opening 210, and one sub-opening 210a is used to accommodate one light-emitting sub-structure 302a. The isolation segment 220 refers to the partial isolation structure 200 located within the same isolation opening 210 and between two adjacent sub-openings 210a.

[0045] Optionally, the display panel further includes a second encapsulation layer 510, located on the side of the first encapsulation layer 400 facing away from the substrate 100. Optionally, the display panel further includes a third encapsulation layer 520, located on the side of the second encapsulation layer 510 facing away from the substrate 100. Adding the third encapsulation layer 520 further improves the sealing effect. Optionally, the material of the second encapsulation layer 510 includes an organic material, which improves the flatness of the second encapsulation layer 510. Optionally, the material of the third encapsulation layer 520 includes an inorganic material, which improves the density of the third encapsulation layer 520 and enhances the encapsulation effect. Optionally, the material of the first encapsulation layer 400 includes an inorganic material, resulting in good density and encapsulation effect of the encapsulation layer.

[0046] In some optional embodiments, referring to Figures 1 through 5, the encapsulation portion 410 includes sub-encapsulation portions 410a for encapsulating sub-units 310a, with at least two adjacent sub-encapsulation portions 410a interconnected. This eliminates gaps between adjacent sub-encapsulation portions 410a, improving the relative positional stability between them and increasing the yield of the sub-encapsulation portions 410a. The adjacent sub-encapsulation portions 410a can cover the isolation segment 220 located between them, increasing the distribution area and encapsulation effect of the sub-encapsulation portions 410a.

[0047] The two interconnected sub-package portions 410a can be any sub-package portion 410a. In some optional embodiments, among the plurality of sub-package portions 410a corresponding to the same light-emitting unit 310, at least two adjacent sub-package portions 410a are interconnected. The plurality of sub-package portions 410a corresponding to the same light-emitting unit 310 refers to the plurality of sub-package portions 410a used to encapsulate the plurality of sub-units 310a in the same light-emitting unit 310.

[0048] In these optional embodiments, the same light-emitting unit 310 includes multiple sub-units 310a, and each sub-unit 310a is provided with a corresponding sub-encapsulation part 410a. The multiple sub-units 310a corresponding to the same light-emitting unit 310 are close to each other. Therefore, in this embodiment, the sub-encapsulation parts 410a that are close to each other are connected to each other, which can simplify the structure and fabrication of the encapsulation part 410.

[0049] Optionally, multiple sub-encapsulation portions 410a corresponding to the same light-emitting unit 310 are interconnected into an integral structure, that is, the light-emitting unit 310 corresponds to one encapsulation portion 410, which can further simplify the structure of the encapsulation portion 410, so that multiple isolation segments 220 corresponding to the same light-emitting unit 310 can be covered by the encapsulation portion 410, and the isolation segments 220 within the same isolation opening 210 can be covered by the encapsulation portion 410, which can further increase the distribution area of ​​the encapsulation portion 410 and improve the encapsulation effect.

[0050] Optionally, the orthographic projection of the isolation segment 220 onto the substrate 100 is located within the orthographic projection of the sub-package portion 410a onto the substrate 100, thereby increasing the distribution area of ​​the package portion 410 and improving the packaging effect.

[0051] In some optional embodiments, referring to Figures 1 and 2, the minimum distance between the sub-openings 210a corresponding to two adjacent and interconnected sub-encapsulation portions 410a within the same light-emitting unit 310 and their corresponding orthogonal projections onto the substrate 100 is the first spacing d1, and the minimum distance between the orthogonal projections of two adjacent isolation openings 210 onto the substrate 100 is the second spacing d2, wherein the first spacing d1 is smaller than the second spacing d2.

[0052] The orthographic projection of the sub-opening 210a onto the substrate 100 is formed by the orthographic projection of the inner wall surface of the isolation structure 200 toward the sub-opening 210a onto the substrate 100. For example, the orthographic projection of the sub-opening 210a onto the substrate 100 is formed by the orthographic projection of the second sub-layer 202 of the isolation structure 200 toward the inner wall surface of the sub-opening 210a onto the substrate 100. Similarly, the orthographic projection of the isolation opening 210 onto the substrate 100 is formed by the orthographic projection of the inner wall surface of the isolation structure 200 toward the isolation opening 210 onto the substrate 100. For example, the orthographic projection of the isolation opening 210 onto the substrate 100 is formed by the orthographic projection of the second sub-layer 202 of the isolation structure 200 toward the inner wall surface of the isolation opening 210 onto the substrate 100.

[0053] In these optional embodiments, the first spacing d1 is smaller, making it easier for adjacent sub-package portions 410a to connect to each other at the position corresponding to the first spacing d1, simplifying the manufacturing process. It also results in a smaller distance between adjacent sub-units 310a within the same light-emitting unit 310, ensuring the light emission effect of the light-emitting unit 310. The second spacing d2 is larger, which can improve the problem of easy crosstalk between different light-emitting units 310 corresponding to the isolation opening 210.

[0054] Optionally, the first spacing d1 is the minimum spacing between two adjacent sub-encapsulation portions 410a in their side-by-side arrangement direction. For example, when they are arranged side-by-side in the first direction X, the first spacing d1 is the minimum spacing between the two adjacent sub-encapsulation portions 410a in the first direction X. Similarly, the second spacing d2 is the minimum spacing between two adjacent isolation openings 210 in their side-by-side arrangement direction. For example, when two adjacent isolation openings 210 are arranged side-by-side along the first direction X, the second spacing d2 is the minimum spacing between the two adjacent isolation openings 210 in the first direction X. In some embodiments of this application, two adjacent sub-encapsulation portions 410a and two adjacent isolation openings 210 are arranged along a third direction P, and the third direction P intersects with the first direction X.

[0055] Optionally, the minimum distance between the orthographic projections of the isolation openings 210 corresponding to two adjacent light-emitting units 310 of different colors onto the substrate 100 is the second spacing d2. A larger second spacing d2 means a larger spacing between the isolation openings 210 corresponding to different color light-emitting units 310, which can improve the problem of easy crosstalk between light emitted from different color light-emitting units 310.

[0056] Multiple isolation openings 210 are arrayed along a first direction X and a second direction Y. The multiple isolation openings 210 can be arranged in various ways. Optionally, the multiple isolation openings 210 include a first isolation opening 211, a second isolation opening 212, and a third isolation opening 213. Multiple light-emitting units 310 include a first light-emitting unit 311 corresponding to the first isolation opening 211, a second light-emitting unit 312 corresponding to the second isolation opening 212, and a third light-emitting unit 313 corresponding to the third isolation opening 213. The first light-emitting unit 311 corresponding to the first isolation opening 211 means that at least a portion of the first light-emitting unit 311 is located within the first isolation opening 211. Similarly, at least a portion of the second light-emitting unit 312 is located within the second isolation opening 212, and at least a portion of the third light-emitting unit 313 is located within the third isolation opening 213. The second spacing d2 can be the minimum spacing between adjacent first isolation openings 211 and second isolation openings 212, or the second spacing d2 can be the minimum spacing between adjacent first isolation openings 211 and third isolation openings 213, or the second spacing d2 can be the minimum spacing between adjacent second isolation openings 212 and third isolation openings 213.

[0057] Optionally, the isolation structure 200 further includes an isolation portion 230 located between two adjacent light-emitting units 310. The isolation portion 230 is located between adjacent isolation openings 210. The width of the isolation portion 230 is greater than the width of the isolation segment 220, so that the spacing between different light-emitting units 310 can be greater than the spacing between sub-units 310a within the light-emitting unit 310. The width of the isolation portion 230 can be understood as the minimum distance between two adjacent isolation openings 210.

[0058] In this embodiment, the isolation portion 230 is located between two adjacent isolation openings 210, and the isolation portion 230 is used to define the isolation openings 210. The isolation segment 220 is located within the isolation opening 210, and the isolation segment 220 is used to divide the isolation opening 210 into two or more sub-openings 210a. The width of the isolation portion 230 is greater than the width of the isolation segment 220, that is, the distance between two adjacent isolation openings 210 is greater than the distance between two adjacent sub-openings 210a within the isolation opening 210, thereby enabling the spacing between adjacent light-emitting units 310 to be greater than the spacing between two adjacent sub-units 310a within the light-emitting unit 310. This improves the light emission effect of the same light-emitting unit 310 while reducing the crosstalk between adjacent light-emitting units 310.

[0059] Optionally, the isolation portion 230 may be located between adjacent first isolation openings 211 and second isolation openings 212, between adjacent first isolation openings 211 and third isolation openings 213, or between adjacent second isolation openings 212 and third isolation openings 213.

[0060] The width direction of the isolation section 230 refers to the direction in which one of the two isolation openings 210 located on both sides of the isolation section 230 points to the other, that is, the side-by-side arrangement direction of the two isolation openings 210 located on both sides of the isolation section 230. The width direction of the isolation segment 220 refers to the direction in which one of the two sub-openings 210a located on both sides of the isolation segment 220 points to the other, that is, the side-by-side arrangement direction of the two sub-openings 210a located on both sides of the isolation segment 220.

[0061] In some optional embodiments, referring to Figures 5 and 6 together, at least two adjacent sub-encapsulation portions 410a are spaced apart in the orthographic projection of the substrate 100. In the same light-emitting unit 310, the minimum distance between the orthographic projections of the sub-openings 210a corresponding to two adjacent and spaced sub-encapsulation portions 410a on the substrate 100 is a third spacing d3, and the minimum distance between the orthographic projections of two adjacent isolation openings 210 on the substrate 100 is a second spacing d2. The third spacing d3 is smaller than the second spacing d2. Optionally, the third spacing d3 is the spacing between two adjacent sub-openings 210a in their side-by-side arrangement direction.

[0062] In these optional embodiments, in the same light-emitting unit 310, the sub-encapsulation portions 410a corresponding to some sub-units 310a are arranged at intervals, and the third spacing d3 is smaller than the second spacing d2. That is, the distance between two adjacent sub-openings 210a corresponding to the same light-emitting unit 310 is smaller than the distance between two adjacent isolation openings 210. This makes the distance between multiple sub-units 310a corresponding to the same light-emitting unit 310 smaller and the spacing between different light-emitting units 310 larger. On the basis of improving the easy crosstalk between the light emitted by two adjacent light-emitting units 310, the light emission effect of the same light-emitting unit 310 is guaranteed.

[0063] And / or, the minimum distance between the sub-openings 210a corresponding to two adjacent and interconnected sub-encapsulation portions 410a within the same light-emitting unit 310 and their projections onto the substrate 100 is the first spacing d1, and the first spacing d1 is less than the third spacing d3.

[0064] In these alternative embodiments, the first spacing d1 is smaller, making it easier for the sub-package portions 410a to connect with each other at this position, and the third spacing d3 is larger, making it easier for adjacent sub-package portions 410a to be spaced apart at this position, which can simplify the manufacturing process.

[0065] In some optional embodiments, at least one light-emitting unit 310 has multiple sub-package portions 410a arranged at intervals in the orthographic projection of the substrate 100. This allows the multiple sub-units 310a corresponding to the multiple light-emitting units 310 to be packaged independently, so that when the packaging of one sub-unit 310a fails, it will not affect the packaging effect of other sub-units 310a, thereby further improving the yield of the display panel.

[0066] Optionally, when the first isolation opening 211 includes at least two sub-openings 210a, and the packaging portions 410 corresponding to the at least two sub-openings 210a are spaced apart, the third spacing d3 can be the spacing between two adjacent sub-openings 210a in the first isolation opening 211. When the second isolation opening 212 includes at least two sub-openings 210a, and the packaging portions 410 corresponding to the at least two sub-openings 210a are spaced apart, the third spacing d3 can be the spacing between two adjacent sub-openings 210a in the second isolation opening 212. When the third isolation opening 213 includes at least two sub-openings 210a, and the packaging portions 410 corresponding to the at least two sub-openings 210a are spaced apart, the third spacing d3 can be the spacing between two adjacent sub-openings 210a in the third isolation opening 213.

[0067] In some optional embodiments, please refer to the above, the isolation structure 200 includes an isolation portion 230 located between two adjacent isolation openings 210, and the orthographic projection of the isolation portion 230 located between two adjacent light-emitting units 310 of the same color on the substrate 100 is located within the orthographic projection of the encapsulation portion 410 corresponding to the two light-emitting units 310 on the substrate 100.

[0068] In these alternative embodiments, the isolation portion 230 is covered by the encapsulation portion 410, which can further increase the distribution area and encapsulation effect of the encapsulation portion 410, thereby improving the yield of the display panel.

[0069] In some optional embodiments, as shown in FIG7, at least two adjacent light-emitting units 310 with the same emission color have their corresponding encapsulation portions 410 interconnected. The light-emitting units 310 with the same emission color and their corresponding encapsulation portions 410 can be fabricated in the same process step. By interconnecting at least two adjacent light-emitting units 310 with the same emission color, the encapsulation portions 410 can be interconnected by retaining a portion of the encapsulation portion 410, thereby increasing the distribution area of ​​the encapsulation portion 410 and simplifying the fabrication process of the encapsulation portion 410.

[0070] In some optional embodiments, at least two adjacent light-emitting units 310 with the same light-emitting color are connected to each other as a single structure.

[0071] In these alternative embodiments, at least two adjacent packaging portions 410 are connected to each other as an integral structure, which can improve the structural strength of the packaging portion 410, thereby improving the yield and sealing effect of the packaging portion 410.

[0072] In some optional embodiments, referring to Figures 3 and 8 together, two adjacent sub-package portions 410a corresponding to an isolation opening 210 are connected to each other to form a continuous region LD. The continuous region LD is located on the side of the isolation segment 220 in the isolation opening 210 that is away from the substrate 100. The orthographic projection of the continuous region LD on the substrate 100 is located within the orthographic projection of the isolation segment 220 on the substrate 100.

[0073] In these optional embodiments, when two adjacent sub-package portions 410a are connected to each other to form a single structure, a continuous region LD can be formed. The continuous region LD is correspondingly disposed on the isolation segment 220 between the corresponding sub-openings 210a of the two adjacent sub-package portions 410a. The orthographic projection of the continuous region LD onto the substrate 100 is located within the orthographic projection of the isolation segment 220 onto the substrate 100, so that the isolation segment 220 can provide support to the continuous region LD.

[0074] Optionally, as shown in Figure 3, the continuous region LD and the isolation segment 220 can be spaced apart from each other. Alternatively, as shown in Figure 8, a redundant unit 340 can be provided between the continuous region LD and the isolation segment 220. During the fabrication of the light-emitting unit 310, some of the light-emitting material and / or the material of the second sub-electrode 303a are not etched and remain between the continuous region LD and the isolation segment 220 to support the continuous region LD. Optionally, the redundant unit 340 includes two sub-layers, one of which is made of the same material as the light-emitting sub-structure 302a, and the other sub-layer is made of the same material as the second sub-electrode 303a.

[0075] In some optional embodiments, as shown in Figures 1 to 7, the projected areas of multiple sub-openings 210a of the same isolation opening 210 on the substrate 100 are the same. The identical areas of the multiple sub-openings 210a allow for the same effective light-emitting area of ​​the multiple sub-units 310a corresponding to the same light-emitting unit 310.

[0076] Optionally, the multiple sub-openings 210a of the same isolation opening 210 have the same orthographic projection shape on the substrate 100. This simplifies the distribution pattern of the isolation structure 200 and facilitates the fabrication and molding of the isolation structure 200.

[0077] Optionally, the two or more light-emitting substructures 302a corresponding to the same light-emitting unit 310 have the same projected area on the substrate 100, so that the effective light-emitting area of ​​multiple sub-units 310a corresponding to the same light-emitting unit 310 can be the same.

[0078] Optionally, two or more light-emitting substructures 302a corresponding to the same light-emitting unit 310 have the same orthographic projection shape on the substrate 100. This simplifies the distribution pattern of the light-emitting units 310 and facilitates the fabrication of the isolation structure 200.

[0079] In some alternative embodiments, as shown in Figures 7 and 9, at least two sub-openings 210a are polygonal in their orthographic projection onto the substrate 100, and the long sides of the orthographic projections of the at least two sub-openings 210a onto the substrate 100 extend in the same direction.

[0080] In these alternative embodiments, the isolation structure 200 has a larger connection area with the second sub-electrode 303a on the long side corresponding to the sub-opening 210a.

[0081] In the fabrication process of the second sub-electrode 303a, a linear evaporation source is typically used to scan the display substrate. The evaporation yield of the second sub-electrode 303a is better in the scanning direction, resulting in a better connection yield between the second sub-electrode 303a and the isolation structure 200. When the evaporation source scans in a direction perpendicular to the long side extension direction, by ensuring that the long sides of at least two sub-openings 210a projected onto the substrate 100 extend in the same direction, the connection yield between the second sub-electrode 303a on the long side of the multiple sub-openings 210a and the isolation structure 200 is better, thereby improving the overall connection yield between the second sub-electrode 303a and the isolation structure 200.

[0082] In some optional embodiments, as shown in Figures 9 and 10, the display panel includes a scan signal line 10 extending along a preset direction. The long side of the sub-opening 210a projected onto the substrate 100 extends along the preset direction, or the long side of the sub-opening 210a projected onto the substrate 100 extends along a direction perpendicular to the preset direction. Optionally, the display panel also includes a data signal line 20, the extension direction of which is perpendicular to the preset direction. Optionally, the preset direction can be a first direction X, and the extension direction of the data signal line 20 can be a second direction Y.

[0083] In these optional embodiments, the scanning direction and the preset direction can be parallel or perpendicular. When the long side corresponding to the sub-opening 210a extends along the preset direction, the scanning direction can be made perpendicular to the preset direction, thereby improving the connection yield between the second sub-electrode 303a and the isolation structure 200. When the long side corresponding to the sub-opening 210a extends along a direction perpendicular to the preset direction, the scanning direction can be made parallel to the preset direction, thereby improving the connection yield between the second sub-electrode 303a and the isolation structure 200.

[0084] In some optional embodiments, as shown in Figures 9 and 10, the display panel includes a display area AA and a bonding area BA arranged along a preset direction. The long side of the sub-opening 210a projected onto the substrate 100 extends along the preset direction, or the long side of the sub-opening 210a projected onto the substrate 100 extends along a direction perpendicular to the preset direction. Optionally, the preset direction can be a first direction X or a second direction Y. This can also improve the connection yield between the second sub-electrode 303a and the isolation structure 200.

[0085] In some alternative embodiments, as shown in Figures 11 and 12, the encapsulation portion 410 includes a sub-encapsulation portion 410a for encapsulating the sub-unit 310a, and at least two adjacent sub-encapsulation portions 410a overlap in the orthographic projection portion of the substrate 100 to form an overlapping region JD, the overlapping region JD being located within the orthographic projection of the isolation segment 220 on the substrate 100.

[0086] In these alternative embodiments, by having two adjacent sub-package portions 410a overlap each other, the distribution area of ​​the sub-package portions 410a can be further increased, thereby improving the packaging effect of the sub-package portions 410a. The two sub-package portions 410a overlap above the isolation segment 220, and the orthographic projection of the overlapping area JD onto the substrate 100 lies within the orthographic projection of the isolation segment 220 onto the substrate 100. This allows the overlapping area JD to be located on the side of the isolation segment 220 away from the substrate 100, thereby mitigating the impact of the sub-package portion 410a extending to the adjacent sub-opening 210a on light emission.

[0087] Optionally, among the plurality of sub-package portions 410a corresponding to the same light-emitting unit 310, at least two adjacent sub-package portions 410a overlap in the orthographic projection portion of the substrate 100. This increases the distribution area of ​​the plurality of sub-package portions 410a corresponding to the same light-emitting unit 310.

[0088] Optionally, as shown in FIG13, the encapsulation portions 410 corresponding to at least two adjacent light-emitting units 310 with different light-emitting colors overlap in the orthographic projection portion of the substrate 100. The light-emitting units 310 with different colors and their corresponding encapsulation portions 410 can be fabricated in different process steps. Therefore, by controlling the encapsulation portions 410 fabricated in different process steps, the encapsulation portions 410 corresponding to at least two adjacent light-emitting units 310 with different light-emitting colors can overlap in the orthographic projection portion of the substrate 100.

[0089] In some optional embodiments, as shown in FIG2, the encapsulation portion 410 includes a first segment 401 and a second segment 402 connected to each other. The first segment 401 is located at the isolation opening 210, and the second segment 402 is located on the side of the isolation structure 200 away from the substrate 100. The orthographic projection of the second segment 402 on the substrate 100 has a first width W. The first width W of the second segment 402 of the encapsulation portion 410 corresponding to at least two light-emitting units 310 with different light-emitting colors is different, and / or the first width W of the second segment 402 of the encapsulation portion 410 corresponding to at least two light-emitting units 310 with the same light-emitting color is the same.

[0090] The second segment 402 refers to the portion of the package 410 located on the side of the isolation structure 200 facing away from the substrate 100. The width of the second segment 402 can be understood as the extension dimension of the second segment 402 in the direction from the isolation opening 210 corresponding to the second segment 402 to the adjacent isolation opening 210. The isolation opening 210 corresponding to the second segment 402 refers to the isolation opening 210 where the first segment 401, which is connected to the second segment 402, is located.

[0091] In these optional embodiments, light-emitting units 310 of different colors and their corresponding encapsulation portions 410 can be fabricated in different process steps. When fabricating encapsulation portions 410 corresponding to light-emitting units 310 of different colors, the first width W of the second segment 402 of the encapsulation portion 410 corresponding to the light-emitting units 310 of different colors can be different to simplify the fabrication process. Light-emitting units 310 of the same color are fabricated in the same process step. Therefore, and / or, at least two light-emitting units 310 of the same color and their corresponding encapsulation portions 410 have the same first width W of the second segment 402, making the light emission effect of the light-emitting units 310 of the same color more consistent.

[0092] Optionally, when the plurality of light-emitting units 310 include a first light-emitting unit 311, a second light-emitting unit 312, and a third light-emitting unit 313, the first width W includes a first sub-width W1 corresponding to the first light-emitting unit 311, a second sub-width W2 corresponding to the second light-emitting unit 312, and a third sub-width W3 corresponding to the third light-emitting unit 313. The first sub-width W1 corresponding to the plurality of first light-emitting units 311 can be the same, the second sub-width W2 corresponding to the plurality of second light-emitting units 312 can be the same, and the third sub-width W3 corresponding to the plurality of third light-emitting units 313 can be the same. The first sub-width W1, the second sub-width W2, and the third sub-width W3 can be different.

[0093] Please refer to the above. Multiple isolation openings 210 include a first isolation opening 211, a second isolation opening 212, and a third isolation opening 213. Multiple light-emitting units 310 include a first light-emitting unit 311, a second light-emitting unit 312, and a third light-emitting unit 313. There are various arrangements of the first isolation openings 211, the second isolation opening 212, and the third isolation opening 213. For example, as shown in Figures 1, 4 to 6, 11, and 13 to 14, the first isolation openings 211 and 212 are alternately arranged along the first direction X to form a first row of openings. Multiple third isolation openings 213 are sequentially arranged along the first direction X to form a second row of openings. The first and second rows of openings are alternately arranged along the second direction Y, and the first and second directions X intersect.

[0094] Optionally, referring to Figure 1, the orthographic projection of the third isolation opening 213 onto the substrate 100 lies within the virtual quadrilateral S1. Two first isolation openings 211 and two second isolation openings 212 are alternately distributed around the periphery of the third isolation opening 213. The centroids of the orthographic projections of the two first isolation openings 211 onto the substrate 100 are located at two opposite vertices of the virtual quadrilateral S1, and the centroids of the orthographic projections of the two second isolation openings 212 onto the substrate 100 are located at another pair of opposite vertices of the virtual quadrilateral S1. The centroid can be understood as the geometric center of a shape. The geometric center generally describes the central position of an object with a certain degree of symmetry, such as the intersection of the two diagonals of a quadrilateral. For an object with a geometric center, when undergoing symmetrical transformations that coincide with itself, its axis of rotation, axis of symmetry, and pivot point must all pass through the geometric center.

[0095] Optionally, as shown in Figures 1, 4 to 6, 11, and 13 to 14, when the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213 are arranged in the manner described above, at least one third isolation opening 213 may include two sub-openings 210a arranged along the extension direction of any one of the diagonals L1 of the virtual quadrilateral S1.

[0096] In these optional embodiments, each of the four vertices of the virtual quadrilateral S1 is provided with an isolation opening 210. The spacing between the virtual quadrilateral S1 along the first direction X and the second direction Y is small. By dividing the third isolation opening 213 into two sub-openings 210a arranged along the diagonal L1 extension direction, the distribution area of ​​the three sub-openings 210a can be appropriately increased, thereby increasing the distribution area of ​​the sub-units 310a and improving the effective light-emitting area.

[0097] The extension direction of diagonal L1 intersects the first direction X and the second direction Y. Optionally, the angle between the extension direction of diagonal L1 and the first direction X and / or the second direction Y is 30 degrees to 50 degrees, for example, the angle between the extension direction of diagonal L1 and the first direction X and / or the second direction Y is 30 degrees, 35 degrees, 40 degrees, 45 degrees, 48 ​​degrees, 50 degrees, etc. When the angle between the extension direction of diagonal L1 and the first direction X and / or the second direction Y is within the above range of 30 degrees to 50 degrees, it can improve the effect of excessively large or small angles on the distribution area of ​​the sub-opening 210a.

[0098] Optionally, when at least one third isolation opening 213 includes two sub-openings 210a arranged along a diagonal L1, at least one third light-emitting unit 313 may include sub-units 310a arranged along a diagonal L1, at least a portion of the sub-units 310a of the third light-emitting unit 313 are located within the sub-openings 210a of the third isolation opening 213, the encapsulation portion 410 includes a third sub-encapsulation portion 413 for encapsulating the sub-units 310a of the third light-emitting unit 313, the isolation segment 220 includes a third isolation segment 223 located within the third isolation opening 213, the third isolation segment 223 divides the third isolation opening 213 into a plurality of sub-openings 210a, and the orthographic projection of the third isolation segment 223 on the substrate 100 is located within the orthographic projection of the third sub-encapsulation portion 413 on the substrate 100.

[0099] In these optional embodiments, a third isolation segment 223 is provided within the third isolation opening 213. The third isolation segment 223 can divide the third isolation opening 213 into two sub-openings 210a. The orthographic projection of the third isolation segment 223 on the substrate 100 is located within the orthographic projection of the third sub-encapsulation portion 413 on the substrate 100. That is, the third sub-encapsulation portion 413 also covers the third isolation segment 223 located between two adjacent sub-openings 210a. This can increase the distribution area of ​​the third sub-encapsulation portion 413, improve the encapsulation effect, and thus improve the yield and performance of the display panel.

[0100] Optionally, multiple third sub-package portions 413 corresponding to the same third light-emitting unit 313 are interconnected. This eliminates gaps between adjacent third sub-package portions 413, improves the relative positional stability between adjacent third sub-package portions 413, increases the yield of the third sub-package portions 413, and allows adjacent third sub-package portions 413 to cover the third isolation segment 223 located between them, thereby increasing the distribution area and packaging effect of the third sub-package portions 413.

[0101] In some optional embodiments, as shown in Figures 4 and 5, at least one of the first isolation opening 211 and the second isolation opening 212 includes two sub-openings 210a arranged along the first direction X, and / or, at least one of the first isolation opening 211 and the second isolation opening 212 includes two sub-openings 210a arranged along the second direction Y.

[0102] In these optional embodiments, the spacing between the first isolation opening 211 and the second isolation opening 212 adjacent along the first direction X and / or the second direction Y is large. The first isolation opening 211 and / or the second isolation opening 212 may include two sub-openings 210a. These two sub-openings 210a can be arranged along the first direction X or the second direction Y, which can appropriately increase the distribution area of ​​the sub-openings 210a, thereby increasing the effective light-emitting area.

[0103] This application embodiment illustrates that both the first isolation opening 211 and the second isolation opening 212 include two sub-openings 210a. When the first isolation opening 211 includes two sub-openings 210a, the corresponding first light-emitting unit 311 includes two sub-units 310a. When the second isolation opening 212 includes two sub-openings 210a, the corresponding second light-emitting unit 312 includes two sub-units 310a.

[0104] Optionally, the first light-emitting unit 311 includes two sub-units 310a, the encapsulation part 410 includes a first sub-encapsulation part 411 for encapsulating the sub-units 310a of the first light-emitting unit 311, and the isolation segment 220 includes a first isolation segment 221 located within the first isolation opening 211. The first isolation segment 221 is used to divide the first isolation opening 211 into two sub-openings 210a. The orthographic projection of the first isolation segment 221 on the substrate 100 is located within the orthographic projection of the first sub-encapsulation part 411 on the substrate 100.

[0105] In these optional embodiments, the orthographic projection of the first isolation segment 221 onto the substrate 100 is located within the orthographic projection of the first sub-package portion 411 onto the substrate 100. That is, the first sub-package portion 411 also covers the first isolation segment 221 located between two adjacent sub-openings 210a, which can increase the distribution area of ​​the first sub-package portion 411, improve the packaging effect, and thus improve the yield and performance of the display panel.

[0106] Optionally, the two first sub-package portions 411 corresponding to the same first light-emitting unit 311 are connected to each other as an integral structure. This eliminates gaps between adjacent first sub-package portions 411, improves the relative positional stability between adjacent first sub-package portions 411, increases the yield of the first sub-package portions 411, and allows adjacent first sub-package portions 411 to cover the first isolation segment 221 located between the two first sub-package portions 411, thereby increasing the distribution area and packaging effect of the first sub-package portions 411.

[0107] Optionally, the second light-emitting unit 312 includes two sub-units 310a, the encapsulation portion 410 includes a second sub-encapsulation portion 412 for encapsulating the sub-units 310a of the second light-emitting unit 312, and the isolation segment 220 includes a second isolation segment 222 located within the second isolation opening 212. The second isolation segment 222 is used to divide the second isolation opening 212 into two sub-openings 210a. The orthographic projection of the second isolation segment 222 on the substrate 100 is located within the orthographic projection of the second sub-encapsulation portion 412 on the substrate 100.

[0108] In these optional embodiments, the orthographic projection of the second isolation segment 222 onto the substrate 100 is located within the orthographic projection of the second sub-package portion 412 onto the substrate 100. That is, the second sub-package portion 412 also covers the second isolation segment 222 located between two adjacent sub-openings 210a, which can increase the distribution area of ​​the second sub-package portion 412, improve the packaging effect, and thereby improve the yield and performance of the display panel.

[0109] Optionally, the two second sub-package portions 412 corresponding to the same second light-emitting unit 312 are connected to each other as a single structure. This eliminates gaps between adjacent second sub-package portions 412, improves the relative positional stability between adjacent second sub-package portions 412, increases the yield of the second sub-package portions 412, and allows adjacent second sub-package portions 412 to cover the second isolation segment 222 located between the two second sub-package portions 412, thereby increasing the distribution area and packaging effect of the second sub-package portions 412.

[0110] In some optional embodiments, the two sub-openings 210a corresponding to the first isolation opening 211 are arranged along the first direction X, and the two sub-openings 210a corresponding to the second isolation opening 212 are also arranged along the first direction X. That is, the arrangement direction of the two sub-openings 210a corresponding to the first isolation opening 211 is the same as the arrangement direction of the two sub-openings 210a corresponding to the second isolation opening 212. This simplifies the distribution pattern of the sub-openings 210a of the multiple isolation openings 210 and makes the light emission effect of the first light-emitting unit 311 and the light emission effect of the second light-emitting unit 312 more consistent, thereby improving the display effect of the display panel.

[0111] In some alternative embodiments, as shown in FIG14, at least one of the first isolation opening 211 and the second isolation opening 212 includes four sub-openings 210a arranged in two rows and two columns along the third direction P and the fourth direction Q, wherein the first direction X, the second direction Y, the third direction P and the fourth direction Q intersect each other and are located in the same plane.

[0112] In these optional embodiments, the first isolation opening 211 and / or the second isolation opening 212 are divided into four sub-openings 210a, which are arranged in two rows and two columns, making the distribution of the four sub-openings 210a more regular and making it easier to make the distribution area of ​​the four sub-openings 210a more consistent.

[0113] Optionally, when the first isolation opening 211 and / or the second isolation opening 212 are divided into multiple sub-openings 210a in the manner described above, at least one of the first light-emitting unit 311 and the second light-emitting unit 312 includes four sub-units 310a arranged in two rows and two columns along the third direction P and the fourth direction Q, so that the arrangement of the first light-emitting unit 311 matches the arrangement of the first isolation opening 211, and the arrangement of the second light-emitting unit 312 matches the arrangement of the second isolation opening 212.

[0114] Optionally, the first direction X and the second direction Y are perpendicular, allowing the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213 to be arranged in a horizontal and vertical direction, resulting in a more uniform distribution of the multiple isolation openings 210.

At least a portion of the first isolation segment 221 is located within the orthographic projection of the first sub-encapsulation part 411 onto the substrate 100.

[0116] In these optional embodiments, the orthographic projection of the first isolation segment 221 onto the substrate 100 is located within the orthographic projection of the first sub-package portion 411 onto the substrate 100. That is, the first sub-package portion 411 also covers the first isolation segment 221 located between two adjacent sub-openings 210a, which can increase the distribution area of ​​the first sub-package portion 411, improve the packaging effect, and thus improve the yield and performance of the display panel.

[0117] Optionally, two first sub-package portions 411 corresponding to the same first light-emitting unit 311 are interconnected. For example, four first sub-package portions 411 corresponding to the same first light-emitting unit 311 are interconnected into a single structure. This eliminates gaps between adjacent first sub-package portions 411, improves the relative positional stability between adjacent first sub-package portions 411, increases the yield of the first sub-package portions 411, and allows adjacent first sub-package portions 411 to cover the first isolation segment 221 located between the two first sub-package portions 411, thereby increasing the distribution area and packaging effect of the first sub-package portions 411.

At least a portion of the second isolation segment 222 is located within the orthographic projection of the second sub-encapsulation part 412 onto the substrate 100.

[0119] In these optional embodiments, the orthographic projection of the second isolation segment 222 onto the substrate 100 is located within the orthographic projection of the second sub-package portion 412 onto the substrate 100. That is, the second sub-package portion 412 also covers the second isolation segment 222 located between two adjacent sub-openings 210a, which can increase the distribution area of ​​the second sub-package portion 412, improve the packaging effect, and thereby improve the yield and performance of the display panel.

[0120] Optionally, two second sub-package portions 412 corresponding to the same second light-emitting unit 312 are interconnected. For example, four second sub-package portions 412 corresponding to the same second light-emitting unit 312 are interconnected into a single structure. This eliminates gaps between adjacent second sub-package portions 412, improves the relative positional stability between adjacent second sub-package portions 412, increases the yield of the second sub-package portions 412, and allows adjacent second sub-package portions 412 to cover the second isolation segment 222 located between the two second sub-package portions 412, thereby increasing the distribution area and packaging effect of the second sub-package portions 412.

[0121] In some alternative embodiments, as shown in Figures 7 and 9, a plurality of first isolation openings 211 are arranged at intervals along the second direction Y to form a first opening column, a plurality of second isolation openings 212 are arranged at intervals along the second direction Y to form a second opening column, and a plurality of third isolation openings 213 are arranged at intervals along the second direction Y to form a third opening column.

[0124] In these optional embodiments, the first isolation opening 211 has a relatively long extension length in the second direction Y. Therefore, the first isolation segment 221 divides the first isolation opening 211 into sub-openings 210a spaced apart along the second direction Y, which can reduce the difference in the extension size of the sub-openings 210a in the first direction X and the second direction Y. In addition, the orthographic projection of the first isolation segment 221 on the substrate 100 is located within the orthographic projection of the first sub-package portion 411 on the substrate 100. That is, the first sub-package portion 411 also covers the first isolation segment 221 located between two adjacent sub-openings 210a, which can increase the distribution area of ​​the first sub-package portion 411, improve the packaging effect, and thus improve the yield and performance of the display panel.

[0125] Optionally, the first isolation segment 221 may extend along the first direction X such that the first isolation segment 221 can divide the first isolation opening 211 into two or more sub-openings 210a spaced along the second direction Y.

The isolation segment 220 includes a second isolation segment 222 located in the second isolation opening 212. The second isolation segment 222 is used to divide the second isolation opening 212 into two or more sub-openings 210a spaced apart along the second direction Y. The orthographic projection of the second isolation segment 222 on the substrate 100 is located within the orthographic projection of the second sub-encapsulation portion 412 on the substrate 100.

[0128] In these optional embodiments, the second isolation opening 212 has a relatively long extension length in the second direction Y. Therefore, the second isolation segment 222 divides the second isolation opening 212 into sub-openings 210a spaced apart along the second direction Y, which can reduce the difference in the extension size of the sub-openings 210a in the second direction Y and the second direction Y. In addition, the orthographic projection of the second isolation segment 222 on the substrate 100 is located within the orthographic projection of the second sub-encapsulation portion 412 on the substrate 100.

[0130] Optionally, the two second sub-package portions 412 corresponding to the same second light-emitting unit 312 are interconnected. This eliminates gaps between adjacent second sub-package portions 412, improves the relative positional stability between adjacent second sub-package portions 412, increases the yield of the second sub-package portions 412, and allows adjacent second sub-package portions 412 to cover the second isolation segment 222 located between the two second sub-package portions 412, thereby increasing the distribution area and packaging effect of the second sub-package portions 412.

[0131] Optionally, the extension dimension of the third isolation opening 213 in the second direction Y is greater than its extension dimension in the second direction Y. The third isolation opening 213 includes two or more sub-openings 210a distributed along the second direction Y. The third light-emitting unit 313 includes two or more sub-units 310a spaced apart along the second direction Y.

The isolation segment 220 includes a third isolation segment 223 located in the third isolation opening 213. The third isolation segment 223 is used to divide the third isolation opening 213 into two or more sub-openings 210a spaced apart along the second direction Y. The orthographic projection of the third isolation segment 223 on the substrate 100 is located within the orthographic projection of the third sub-encapsulation part 413 on the substrate 100.

[0132] In these optional embodiments, the third isolation opening 213 has a relatively long extension length in the second direction Y. Therefore, the third isolation segment 223 divides the third isolation opening 213 into sub-openings 210a spaced apart along the second direction Y, which can reduce the difference in the extension size of the sub-openings 210a in the second direction Y and the second direction Y. In addition, the orthographic projection of the third isolation segment 223 on the substrate 100 is located within the orthographic projection of the third sub-encapsulation portion 413 on the substrate 100. That is, the third sub-encapsulation portion 413 also covers the third isolation segment 223 located between two adjacent sub-openings 210a, which can increase the distribution area of ​​the third sub-encapsulation portion 413, improve the encapsulation effect, and thus improve the yield and performance of the display panel.

[0133] Optionally, the third isolation segment 223 may extend along the first direction X such that the third isolation segment 223 can divide the third isolation opening 213 into two or more sub-openings 210a spaced along the second direction Y.

[0134] Optionally, the two third sub-package portions 413 corresponding to the same third light-emitting unit 313 are interconnected. This eliminates gaps between adjacent third sub-package portions 413, improves the relative positional stability between adjacent third sub-package portions 413, increases the yield of the third sub-package portions 413, and allows adjacent third sub-package portions 413 to cover the third isolation segment 223 located between them, thereby increasing the distribution area and packaging effect of the third sub-package portions 413.

[0135] In some alternative embodiments, as shown in Figures 15 and 16, the first isolation opening 211 and the third isolation opening 213 are alternately arranged along the second direction Y to form a fourth opening column, and a plurality of second isolation openings 212 are sequentially arranged along the second direction Y to form a fifth opening column. The fourth and fifth opening columns are alternately arranged along the first direction X. One first isolation opening 211 and one third isolation opening 213 in the fourth opening column are arranged with the same second isolation opening 212 in the fifth opening column along the first direction X, and the first direction X intersects the second direction Y. When the plurality of isolation openings 210 are arranged in the above manner, the spacing between the first isolation opening 211, the second isolation opening 212 and the third isolation opening 213 can be reduced, thereby reducing the spacing between the first light-emitting unit 311, the second light-emitting unit 312 and the third light-emitting unit 313, so as to improve the display effect.

[0136] Optionally, at least one of the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213 includes two or more sub-openings 210a spaced apart; that is, an isolation segment 220 can be provided in at least one of the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213 to form a sub-opening 210a.

[0137] Optionally, the second isolation opening 212 includes two or more sub-openings 210a spaced apart along the second direction Y. Since the second isolation opening 212 is configured to correspond to the first isolation opening 211 and the third isolation opening 213, its extension dimension in the second direction Y is relatively long. By dividing the second isolation opening 212 into two sub-openings 210a distributed along the second direction Y, the dimensional difference between each sub-opening 210a in the first direction X and the second direction Y is minimized.

[0138] Alternatively, the second isolation opening 212 includes four sub-openings 210a arranged in two rows and two columns along the first direction X and the second direction Y, such that the shapes of the separated sub-openings 210a and the second isolation opening 212 are similar.

[0140] Optionally, as shown in FIG15, the first isolation opening 211 and / or the third isolation opening 213 include two or more sub-openings 210a spaced apart along the first direction X. This makes the sub-openings 210a separated by the first isolation opening 211 and / or the third isolation opening 213 have a longer dimension in the second direction Y, extending in the same direction as the long side of the second isolation opening 212, thereby improving the overlap yield of the second sub-electrode 303a and the isolation structure 200.

[0141] Alternatively, as shown in Figure 16, the first isolation opening 211 and / or the third isolation opening 213 include four sub-openings 210a arranged in two rows and two columns along the first direction X and the second direction Y.

[0147] Optionally, the two second sub-package portions 412 corresponding to the same second light-emitting unit 312 are interconnected.

The encapsulation portion 410 of the first encapsulation layer 400 can provide encapsulation protection to the light-emitting unit 310. The multiple first sub-electrodes 301a of the same light-emitting unit 310 are electrically connected to each other, so that the multiple sub-units 310a of the same light-emitting unit 310 can be driven by the same pixel circuit 110, which simplifies the structure of the pixel circuit 110. The orthographic projection of the isolation segment 220 on the substrate 100 is located within the orthographic projection of the encapsulation portion 410 on the substrate 100. That is, the encapsulation portion 410 also covers the isolation segment 220 located between two adjacent sub-units 310a, which can increase the distribution area of ​​the encapsulation portion 410, improve the encapsulation effect, and thus improve the yield and performance of the display panel.

[0160] As shown in Figures 1 to 19, an embodiment of the second aspect of this application also provides a display panel, comprising: a substrate 100; an isolation structure 200 located on one side of the substrate 100, the isolation structure 200 enclosing an isolation opening 210, the isolation structure 200 including an isolation segment 220 disposed within at least one isolation opening 210 and dividing the isolation opening 210 into at least two sub-openings 210a; and a light-emitting layer 300 located on one side of the substrate 100, the light-emitting layer 300 including light-emitting units 310, at least a portion of the light-emitting units 310 being located within the isolation opening 210, and at least one light-emitting unit 310 including two or more sub-openings spaced apart. The element 310a, at least a portion of the sub-unit 310a is located within the sub-opening 210a, the sub-unit 310a includes a first sub-electrode 301a, a light-emitting sub-structure 302a and a second sub-electrode 303a stacked in a direction away from the substrate 100; the first encapsulation layer 400 includes an encapsulation portion 410 for encapsulating the light-emitting unit 310, the encapsulation portion 410 includes a sub-encapsulation portion 410a for encapsulating the sub-unit 310a, wherein the first sub-electrodes 301a of the plurality of sub-units 310a of the same light-emitting unit 310 are electrically connected to each other, and the orthographic projection of the isolation segment 220 on the substrate 100 and the orthographic projection of the sub-encapsulation portion 410a on the substrate 100 overlap.

[0161] In the display panel provided in this embodiment, the display panel includes a substrate 100, an isolation structure 200, a light-emitting layer 300, and a first encapsulation layer 400. At least a portion of the light-emitting units 310 of the light-emitting layer 300 is located within the isolation opening 210. The light-emitting unit 310 includes two or more sub-units 310a spaced apart.

[0162] Optionally, as shown in Figure 6, at least two adjacent sub-package portions 410a are spaced apart, so that the packaging of each sub-unit 310a is independent of each other. Optionally, among the multiple sub-package portions 410a corresponding to the same light-emitting unit 310, two adjacent sub-package portions 410a are spaced apart. This makes it difficult for packaging defects to be transmitted in the packaging portion 410 corresponding to the same light-emitting unit 310, improving the packaging effect of a single light-emitting unit 310.
