[0002] Display devices using organic light-emitting diode (OLED) technology have advantages such as good display effect, good heat dissipation, low cost, and small thickness.

[0003] However, the performance of OLED display devices needs further improvement. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, this application provides a display panel including a substrate, an isolation structure, a plurality of light-emitting units, and a first encapsulation layer. The isolation structure is disposed on one side of the substrate along its thickness direction and defines a plurality of isolation openings. The light-emitting units are disposed on one side of the substrate along its thickness direction and are located on the side where the isolation structure is located. The light-emitting units are disposed in at least a portion of the isolation openings. The first encapsulation layer is located on the side of the light-emitting units facing away from the substrate, and the first encapsulation layer includes a plurality of encapsulation portions. At least one encapsulation portion has its apex angle of its orthographic projection onto the substrate located within the orthographic projections of adjacent encapsulation portions onto the substrate.

[0007] Through the above technical solution, to prevent the apex corner of the package from breaking or detaching during the manufacturing process of the display panel, the apex corner of at least one package's orthographic projection on the substrate is located within the orthographic projections of multiple adjacent package portions on the substrate. This helps to mitigate the risk of the apex corner of the package breaking or detaching during the manufacturing process of the display panel.

[0080] Please refer to the following: Figure 1 , Figure 2 and Figure 3 This application provides a display panel 100, which can be an organic light-emitting diode (OLED) display panel 100 or a micro light-emitting diode (Micro LED / μLED) display panel 100.

[0081] The display panel 100 includes a substrate 10, which includes a display area AA and a non-display area NA, with the non-display area NA surrounding at least a portion of the display area AA.

[0082] The display panel 100 also includes a plurality of light-emitting units, which are located along the thickness direction of the substrate 10 (e.g., ...). Figure 3 On one side (in the Z direction), multiple light-emitting units can be fabricated in batches according to the process flow. For example, the multiple light-emitting units may include a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit, which can emit light of different colors. For example, the first light-emitting unit can emit red light, the second light-emitting unit can emit green light, and the third light-emitting unit can emit blue light.

[0084] In some embodiments, the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit can be patterned using a photomask.

[0085] In some embodiments, the display panel 100 further includes a pixel defined layer (PDL) 30 and an isolation structure 40. The isolation structure 40 and the pixel defined layer 30 are disposed on the same side of the substrate 10 along the thickness direction, and the isolation structure 40 is disposed on the side of the pixel defined layer 30 facing away from the substrate 10, defining a plurality of isolation openings. The orthographic projection of the light-emitting unit onto the substrate 10 can be located within the orthographic projection of the corresponding isolation opening onto the substrate 10. Optionally, the pixel defined layer 30 and the isolation structure 40 can be located in the display area AA. It is understood that the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit can be patterned using the isolation structure 40 instead of a photomask. The pixel defined layer 30 has pixel openings located within the isolation openings.

[0086] The multiple isolation openings may include a first isolation opening 401, a second isolation opening 402 and a third isolation opening 403, with the first light-emitting unit corresponding to the first isolation opening 401, the second light-emitting unit corresponding to the second isolation opening 402 and the third light-emitting unit corresponding to the third isolation opening 403.

[0087] The display panel 100 also includes a first electrode layer, a portion of which is located between the pixel definition layer 30 and the substrate 10.

[0088] It is understood that the first electrode 20 of the light-emitting unit is located on the side of the pixel definition layer 30 facing the substrate 10. The light-emitting unit includes a light-emitting layer 50 and a second electrode 60 located on the side of the light-emitting layer 50 away from the substrate 10. The light-emitting layer 50 and the second electrode 60 of the light-emitting unit are located in the isolation opening, and the light-emitting layer 50 is located between the first electrode 20 and the second electrode 60.

[0089] Optionally, the first electrode 20 can be an anode, and the second electrode 60 can be a cathode.

[0090] It is understood that the light-emitting layer 50 of the first light-emitting unit is the first light-emitting layer 51, the light-emitting layer 50 of the second light-emitting unit is the second light-emitting layer 52, and the light-emitting layer 50 of the third light-emitting unit is the third light-emitting layer 53.

[0091] It should be noted that the composition and preparation of the isolation structure 40 are specified in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, and PCT / CN2024 / 09907. 2. Further descriptions are provided in CN117979755A, CN117998900A, CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, and CN117500332A for reference.

[0092] The display panel 100 further includes a first encapsulation layer 70, which is disposed on the side of the pixel definition layer 30 opposite to the substrate 10 and located on the side of the light-emitting unit opposite to the substrate 10. The first encapsulation layer 70 is adjacent to the light-emitting unit. The first encapsulation layer 70 includes a plurality of encapsulation portions, which cover corresponding isolation openings and light-emitting units. In other words, the orthographic projection of the isolation opening on the substrate 10 lies within the orthographic projection of the corresponding encapsulation portion on the substrate 10, and the orthographic projection of the light-emitting unit on the substrate 10 lies within the orthographic projection of the corresponding encapsulation portion on the substrate 10.

[0093] The multiple encapsulation portions may include a first encapsulation portion 71, a second encapsulation portion 72, and a third encapsulation portion 73. The first encapsulation portion 71 corresponds to the first light-emitting unit and is also formed by patterning. The second encapsulation portion 72 corresponds to the second light-emitting unit and is also formed by patterning. The third encapsulation portion 73 corresponds to the third light-emitting unit and is also formed by patterning. Furthermore, the fabrication order of the first encapsulation portion 71, the second encapsulation portion 72, and the third encapsulation portion 73 is consistent with the fabrication order of the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit.

[0094] Please continue reading. Figure 1 , Figure 2 and Figure 3 The inventors discovered that the first encapsulation layer 70 is typically used to encapsulate the light-emitting unit after its formation, and the multiple encapsulation portions of the first encapsulation layer 70 can encapsulate different light-emitting units. The edges of the encapsulation portions typically have apex corners 7011. During the manufacturing process of the display panel 100, the edges of the encapsulation portions, especially the apex corners 7011, are prone to breakage or even detachment, resulting in reduced encapsulation reliability of the first encapsulation layer 70 and affecting the performance of the display panel 100 and the display device.

[0095] Optionally, the package portion may have an extension 701, which is located on the side of the isolation structure 40 away from the substrate 10, and the orthographic projection of the extension 701 on the substrate 10 is within the orthographic projection of the isolation structure 40 on the substrate 10. That is, the apex 7011 of the orthographic projection of the package portion on the substrate 10 is within the orthographic projection of the extension 701 on the substrate.

[0096] It is understood that the apex corner 7011 of the package portion is located at the edge of the extension portion 701, and the apex corner 7011 of the package portion as an orthographic projection on the substrate 10 is the same as the orthographic projection of the apex corner 7011 of the package portion on the substrate 10.

[0097] Please refer to the following: Figure 4 and Figure 5 To address the aforementioned technical problems, this application provides a display panel 100. In this display panel 100, the first encapsulation layer 70 includes multiple encapsulation portions, each of which may include an extension 701 located on the side of the isolation structure 40 facing away from the substrate 10. In this way, the encapsulation portions can fully cover the light-emitting units, improving the encapsulation effect of the encapsulation portions on the light-emitting units.

[0098] Optionally, the light-emitting units are disposed in at least a portion of the isolation openings. In some examples, there is a one-to-one correspondence between the light-emitting units and the isolation openings. In other examples, the number of isolation openings is greater than the number of light-emitting units, and the light-emitting layer 50 and the second electrode 60 in the partial isolation openings are not energized. That is, the light-emitting layer 50 and the second electrode 60 in the partial isolation openings are virtual structures and do not emit light.

[0099] Furthermore, the edge of the extension 701 has at least one apex corner 7011, that is, the encapsulation portion has at least one apex corner 7011. The apex corner 7011 of the orthographic projection of at least one encapsulation portion on the substrate 10 is located within the orthographic projection of adjacent encapsulation portions on the substrate 10, which helps to mitigate the breakage and detachment of the apex corner 7011 of the extension encapsulation portion during the fabrication of the display panel 100. Optionally, the number of apex corners 7011 of the encapsulation portion can be one, two, three, four, etc.

[0100] It is understood that the apex corner 7011 of the encapsulation portion can protect the apex corner 7011 of other adjacent encapsulation portions, or the apex corner 7011 of the encapsulation portion can be protected by the apex corner 7011 of other adjacent encapsulation portions. In this way, the display panel 100 provided in this application can protect the apex corner 7011 of the encapsulation portion to a certain extent, avoiding breakage or detachment of the apex corner 7011 of the edge of the extension portion 701 during the manufacturing process of the display panel 100, which is beneficial to improving the reliability of the encapsulation and thus improving the performance.

[0101] Therefore, the display panel 100 provided in this application embodiment can improve the performance of the display device.

[0102] Please continue reading. Figure 4 Optionally, the encapsulation portion includes a first encapsulation portion 71 and a second encapsulation portion 72, and the light-emitting unit includes a first light-emitting unit and a second light-emitting unit with different light-emitting colors. The orthographic projection of the first light-emitting unit on the substrate 10 lies within the orthographic projection of the corresponding first encapsulation portion 71 on the substrate 10, and the orthographic projection of the second light-emitting unit on the substrate 10 lies within the orthographic projection of the corresponding second encapsulation portion 72 on the substrate 10. At least one apex corner 7011 of the orthographic projection of the first encapsulation portion 71 on the substrate 10 lies within the orthographic projection of adjacent second encapsulation portions 72 on the substrate 10. This makes the apex corner 7011 of the first encapsulation portion 71 less prone to breakage and detachment, thereby improving encapsulation reliability.

[0103] Optionally, at least one apex 7011 of the orthographic projection of the first package portion 71 on the substrate 10 overlaps with at least one apex 7011 of the orthographic projection of the second package portion 72 on the substrate 10. In this way, the apex 7011 of the second package portion 72 is less likely to break or fall off.

[0104] In addition, the second encapsulation part 72 can provide mutual protection with the first encapsulation part 71, making it less likely for the top corner 7011 of the first encapsulation part 71 and the top corner 7011 of the second encapsulation part 72 to break or fall off.

[0105] Optionally, the encapsulation unit further includes a third encapsulation unit 73, and the light-emitting unit further includes a third light-emitting unit. The light-emitting color of the third light-emitting unit is different from the light-emitting color of the first light-emitting unit and the light-emitting color of the second light-emitting unit. The orthographic projection of the third light-emitting unit on the substrate 10 is located within the orthographic projection of the corresponding third encapsulation unit 73 on the substrate 10. At least one apex 7011 of the orthographic projection of the third encapsulation unit 73 on the substrate 10 is located within the orthographic projection of the adjacent plurality of second encapsulation units 72 on the substrate 10. This makes the apex 7011 of the third encapsulation unit 73 less prone to breakage and detachment, thereby improving the encapsulation reliability.

[0106] Optionally, at least one apex 7011 of the orthographic projection of the third package portion 73 on the substrate 10 overlaps with at least one apex 7011 of the orthographic projection of the second package portion 72 on the substrate 10. In this way, the apex 7011 of the second package portion 72 is less likely to break or fall off.

[0107] In addition, the third encapsulation part 73 can provide mutual protection with the first encapsulation part 71, making it less likely for the top corner 7011 of the first encapsulation part 71 and the top corner 7011 of the third encapsulation part 73 to break or fall off.

[0108] Please continue reading. Figure 4In some embodiments, there are multiple second light-emitting units, which are arranged at intervals around the first light-emitting unit. That is, the second encapsulation portion 72 may be arranged around the first encapsulation portion 71.

[0109] In this design, the orthographic projection of a first package portion 71 onto the substrate 10 has N vertices 7011. The N vertices 7011 of the orthographic projection of the same first package portion 71 onto the substrate 10 are located within the orthographic projections of N adjacent second package portions 72 onto the substrate 10, where N is an integer greater than or equal to 3. That is, the vertices 7011 of the first package portion 71 correspond one-to-one with the adjacent second package portion 72. This makes the vertices 7011 of the first package portion 71 less prone to breakage and detachment, thereby improving package reliability. For example, the orthographic projection of each vertices 7011 of the first package portion 71 onto the substrate 10 overlaps with the orthographic projection of the vertices 7011 of the second package portion 72 onto the substrate 10.

[0110] In this way, the second encapsulation part 72 can provide mutual protection with the first encapsulation part 71, making it less likely for the top corner 7011 of the first encapsulation part 71 and the top corner 7011 of the second encapsulation part 72 to break or fall off.

[0111] In some embodiments, a plurality of second light-emitting units are arranged at intervals around a third light-emitting unit, that is, the second encapsulation portion 72 may be arranged around the first encapsulation portion 71.

[0112] In this design, the orthographic projection of a third package portion onto the substrate has N vertices, and the N vertices of the orthographic projection of the same third package portion onto the substrate are located within the orthographic projections of the N adjacent second package portions onto the substrate. That is, the vertices 7011 of the third package portion 73 correspond one-to-one with the adjacent second package portions 72. This makes the vertices 7011 of the third package portion 73 less prone to breakage and detachment, thereby improving package reliability.

[0113] For example, the orthographic projection of each apex 7011 of the third package 73 on the substrate 10 overlaps with the orthographic projection of the apex 7011 of the second package 72 on the substrate 10.

[0114] In this way, the second encapsulation part 72 and the third encapsulation part 73 can protect each other, making it less likely for the top corner 7011 of the third encapsulation part 73 and the top corner 7011 of the second encapsulation part 72 to break or fall off.

[0115] Please continue reading. Figure 4 In some embodiments, at least one apex corner 7011 of the second package portion 72 is projected onto the substrate 10 within the projection of the first package portion 71 onto the substrate 10.

[0116] Optionally, at least one apex corner 7011 of the second package portion 72 is projected onto the substrate 10 within the projection of the third package portion 73 onto the substrate 10.

[0117] Optionally, the orthographic projection of each apex 7011 of the second package 72 onto the substrate 10 lies within the orthographic projection of the apex 7011 of the first package 71 or the apex 7011 of the third package 73 onto the substrate 10. It is understood that the first package 71 and the third package 73 surround the second package 72, with a portion of the apex 7011 of the second package 72 overlapping with the apex 7011 of the first package 71, and the remaining portion overlapping with the apex 7011 of the third package 73. Therefore, the second package 72 can provide mutual protection with the first package 71, and simultaneously, the second package 72 can provide mutual protection with the third package 73.

[0118] Optionally, there are multiple first light-emitting units and multiple third light-emitting units, with the multiple first light-emitting units and multiple third light-emitting units arranged alternately around the second light-emitting unit. That is, multiple first encapsulation portions 71 and multiple third encapsulation portions 73 are arranged alternately around the second encapsulation portion 72. When there are multiple apex corners 7011 of the second encapsulation portion 72, the orthographic projection of one of two adjacent apex corners 7011 of the second encapsulation portion 72 on the substrate 10 overlaps with the orthographic projection of the apex corner 7011 of the first encapsulation portion 71 on the substrate 10, and the orthographic projection of the other of two adjacent apex corners 7011 of the second encapsulation portion 72 on the substrate 10 overlaps with the orthographic projection of the apex corner 7011 of the third encapsulation portion 73 on the substrate 10.

[0119] Please continue reading. Figure 5 First direction (e.g.) Figure 5 (in the X direction) and the second direction (such as) Figure 5 The Y direction in the first direction is parallel to the substrate 10, and the second direction is perpendicular to the second direction.

[0120] Optionally, along the first direction, the first light-emitting unit and the third light-emitting unit are arranged alternately, and the second light-emitting unit is located between adjacent first and third light-emitting units. That is, along the first direction, the first encapsulation portion and the third encapsulation portion are arranged alternately. Specifically, along the first direction, the first encapsulation portion 71 and the third encapsulation portion 73 are arranged alternately, and the second encapsulation portion 72 is located between the first encapsulation portion 71 and the third encapsulation portion 73. It is understood that the orthographic projection of the second encapsulation portion 72 on the substrate 10 can overlap with the orthographic projections of the first encapsulation portion 71 and the third encapsulation portion 73 on the substrate 10, which can improve the encapsulation reliability of the first encapsulation layer 70.

[0121] Optionally, along the second direction, the first light-emitting unit and the third light-emitting unit are arranged alternately, and the orthographic projection of the first encapsulation portion 71 on the substrate 10 overlaps with the orthographic projection of the third encapsulation portion 73 on the substrate 10. That is, along the second direction, the first encapsulation portion 71 and the third encapsulation portion 73 are arranged alternately, and the orthographic projection of the first encapsulation portion 71 on the substrate 10 overlaps with the orthographic projection of the third encapsulation portion 73 on the substrate in sequence. This can further improve the encapsulation reliability of the first encapsulation layer 70.

[0151] Please refer to the following: Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 In some embodiments, the extension 701 of the fourth encapsulation portion 74 is located on the side of the extension 701 of the first encapsulation portion 71 facing away from or towards the substrate 10; and / or, the extension 701 of the fourth encapsulation portion 74 is located on the side of the extension 701 of the second encapsulation portion 72 facing away from or towards the substrate 10; and / or, the extension 701 of the fourth encapsulation portion 74 is located on the side of the extension 701 of the third encapsulation portion 73 facing away from or towards the substrate 10. The extension 701 of the fourth encapsulation portion 74 can interact with the extensions 701 of the first encapsulation portion 71, the second encapsulation portion 72, and the third encapsulation portion 73, respectively, to improve the situation where the apex corner 7011 of the extension 701 breaks or falls off.

[0152] Optionally, the extension 701 of the fourth packaging portion 74 is located on the side of the extension 701 of the first packaging portion 71 away from the substrate 10, the extension 701 of the fourth packaging portion 74 is located on the side of the extension 701 of the second packaging portion 72 away from or towards the substrate 10, and the extension 701 of the fourth packaging portion 74 is located on the side of the extension 701 of the third packaging portion 73 towards the substrate 10.

[0153] The first encapsulation part 71, the second encapsulation part 72, and the third encapsulation part 73 are formed sequentially.

[0154] It is understood that the fourth package portion 74 may include a first portion, a second portion, and a third portion. The first portion may be formed together with the first package portion 71, the second portion may be formed together with the second package portion 72, and the third portion may be formed together with the third package portion 73. The first portion of the fourth package portion 74 is located on the side of the second package portion 72 and the third package portion 73 facing the substrate 10. The second portion of the fourth package portion 74 is located on the side of the first package portion 71 away from the substrate 10. The second portion of the fourth package portion 74 may also be located on the side of the third package portion 73 facing the substrate 10. The third portion of the fourth package portion 74 is located on the side of the second package portion 72 and the first package portion 71 away from the substrate 10.

[0155] Optionally, the extension 701 of the fourth packaging portion 74 is located on the side of the extension 701 of the first packaging portion 71 facing away from the substrate 10, the extension 701 of the fourth packaging portion 74 is located on the side of the extension 701 of the second packaging portion 72 facing away from the substrate 10, and the extension 701 of the fourth packaging portion 74 is located on the side of the extension 701 of the third packaging portion 73 facing away from the substrate 10. In this way, the extension 701 of the fourth packaging portion 74 can protect the extensions 701 of the first packaging portion 71, the second packaging portion 72, and the third packaging portion 73, respectively.

[0156] The fourth encapsulation part 74 can be prepared after the first encapsulation part 71, the second encapsulation part 72, and the third encapsulation part 73 have been formed.

[0157] Please refer to the following: Figure 10 , Figure 12 and Figure 13 Multiple fourth encapsulation portions 74 are spaced apart around the second encapsulation portion 72. The orthographic projection of each apex 7011 of the second encapsulation portion 72 onto the substrate 10 can overlap with the orthographic projection of the apex 7011 of the fourth encapsulation portion 74 onto the substrate 10. Therefore, the fourth encapsulation portions 74 and the second encapsulation portions 72 can provide mutual protection.

[0158] Please refer to the following: Figure 10 , Figure 14 and Figure 15 Multiple fourth encapsulation portions 74 are spaced apart around the third encapsulation portion 73. The orthographic projection of each apex 7011 of the third encapsulation portion 73 onto the substrate 10 can overlap with the orthographic projection of the apex 7011 of the fourth encapsulation portion 74 onto the substrate 10. Therefore, the fourth encapsulation portions 74 and the third encapsulation portions 73 can provide mutual protection.

[0159] Please refer to the following: Figure 10 , Figure 16 and Figure 17 Multiple fourth encapsulation portions 74 are spaced apart around the first encapsulation portion 71. The orthographic projection of each apex 7011 of the first encapsulation portion 71 onto the substrate 10 can overlap with the orthographic projection of the apex 7011 of the fourth encapsulation portion 74 onto the substrate 10. Therefore, the fourth encapsulation portions 74 and the first encapsulation portion 71 can provide mutual protection.

[0160] The display panel 100 provided in this embodiment further includes a first electrode layer and a pixel definition layer 30. The first electrode layer is located on one side of the substrate 10 along the thickness direction, and the pixel definition layer 30 is located on the side of the first electrode layer away from the substrate 10. An isolation structure 40 is disposed on the side of the pixel definition layer 30 away from the substrate 10. The first electrode layer includes a plurality of spaced first electrodes 20, and the pixel definition layer 30 has a pixel opening that exposes a portion of the first electrodes 20. The light-emitting unit includes a light-emitting layer 50 and a second electrode 60 sequentially disposed along the direction away from the substrate 10. The light-emitting layers 50 of the first, second, and third light-emitting units pass through the pixel openings and are connected to the first electrodes 20. The orthographic projection of the fourth isolation opening 404 on the substrate 10 is spaced apart from the orthographic projection of the first electrode 20 on the substrate 10, meaning that the light-emitting layer 50 in the fourth isolation opening 404 is not connected to the first electrode 20.

[0161] In this way, the first, second, and third light-emitting units can all emit light. It is understood that the first, second, and third light-emitting units emit different colors. However, the light-emitting layer 50 in the fourth isolation opening 404 does not emit light. The display panel 100 of this embodiment has a light-emitting layer 50 in the fourth isolation opening 404, which facilitates the processing of the fourth encapsulation part 74, which covers the light-emitting layer 50 in the fourth isolation opening 404.

That is, the apex corner 7011 of at least one encapsulation portion can overlap with the extension 701 of an adjacent encapsulation portion, which helps to alleviate the breakage and detachment of the apex corner 7011 of the encapsulation portion during the manufacturing process of the display panel 100, which helps to improve the encapsulation reliability and thus improve the performance.

[0163] Optionally, the apex 7011 of each package portion may overlap with the extension 701 of the adjacent package portion.

[0164] Optionally, the apex angle 7011 of the orthographic projection of the first packaging portion 71 on the substrate 10 overlaps with the apex angle 7011 of the orthographic projection of the second packaging portion 72 on the substrate 10, and the apex angle 7011 of the orthographic projection of the third packaging portion 73 on the substrate 10 overlaps with the apex angle 7011 of the orthographic projection of the second packaging portion 72 on the substrate, and the orthographic projections of the first packaging portion 71 and the third packaging portion 73 on the substrate 10 are spaced apart.

[0165] Optionally, the apex angle 7011 of the orthographic projection of the first package portion 71 on the substrate 10 overlaps with the apex angle 7011 of the orthographic projection of the fourth package portion 74 on the substrate 10; the apex angle of the orthographic projection of the second package portion 72 on the substrate 10 overlaps with the apex angle 7011 of the orthographic projection of the fourth package portion 74 on the substrate 10; and the apex angle 7011 of the orthographic projection of the third package portion 73 on the substrate 10 overlaps with the apex angle 7011 of the orthographic projection of the fourth package portion 74 on the substrate 10. The orthographic projections of the first package portion 71 on the substrate 10 are spaced apart from the orthographic projections of the second package portion 72 and the third package portion 73 on the substrate 10.

[0166] Similarly, please refer to the following: Figure 4 , Figure 5, Figure 6 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the light-emitting unit includes a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit with different light-emitting colors. A first encapsulation part 71 covers the first light-emitting unit, a second encapsulation part 72 covers the second light-emitting unit, and a third encapsulation part 73 covers the third light-emitting unit.

[0167] Please refer to the following: Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 The fourth isolation opening 404 has a non-luminescent light-emitting layer 50. The orthographic projection of the fourth encapsulation part 74 on the substrate 10 is spaced apart from the orthographic projection of the light-emitting unit on the substrate 10.

[0168] Optionally, please refer to Figure 18 In some embodiments, the display panel 100 provided in this application may further include a second encapsulation layer 80 and a third encapsulation layer 90, wherein the second encapsulation layer 80 is located on the side of the first encapsulation layer 70 away from the substrate 10, and the third encapsulation layer 90 is located on the side of the second encapsulation layer 80 away from the substrate 10.
