[0087] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent identical or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0088] Although relative terms such as "upper" and "lower" are used in this specification to describe the relationship of one illustrated component to another, these terms are used herein for convenience only, such as in accordance with the orientation of the illustrations in the accompanying drawings. It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.

[0089] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0090] In this application, unless otherwise specified or limited, the term "connected" should be understood broadly. For example, "connected" can mean fixed, removable, or integrated; it can be directly connected or indirectly connected through an intermediary. "And / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0091] The inventors have discovered that the main reason why narrow-framed display panels are prone to generating GDS (Growing Dark Spot) in the display area AA is that the edge strength of the narrow-framed display panel is insufficient, and cracks formed by stress after collision continue to extend toward the display area AA. In addition, since the film layer of the driving substrate 2 in the non-display area NA is made of inorganic material, the texture of inorganic material is relatively brittle and more prone to cracking, causing water / oxygen in the air to erode the luminescent material through the cracks, forming a continuously growing GDS (Growing Dark Spot).

[0092] An example embodiment of the present disclosure provides a display panel, as shown in Figures 1 to 20, the display panel has a display area AA and a non-display area NA adjacent to the display area AA, the non-display area NA may include an isolation area GL, the display panel may include a base substrate 1 and a functional layer group 5; the functional layer group 5 is provided on one side of the base substrate 1, and at least one circle of isolation structure 51 is provided on the functional layer group 5, the isolation structure 51 is located in the isolation area GL, the isolation structure 51 may include a plurality of isolation rings 511, and the orthographic projection of the isolation ring 511 on the base substrate 1 is set as a ring.

[0093] In the display panel disclosed herein, after the edge of the display panel is hit, the multiple isolation rings 511 of at least one circle of isolation structure 51 can disperse the collision force multiple times, making it less likely for the display panel to crack, preventing water / oxygen in the air from corroding the luminescent material through the cracks, and preventing the formation of continuously growing black spots.

[0094] 1 , the display panel may include a display area AA for displaying an image and a non-display area NA for not displaying an image. Display and touch functions may be implemented in the display area AA. The non-display area NA can be arranged to surround the display area AA, that is, the non-display area NA is surrounded by the periphery of the display area AA; the non-display area NA may include a circuit area XL, a packaging dam area FZB and an isolation area GL; the circuit area XL is connected to the side of the edge line 11 of the display area AA close to the base substrate 1, that is, the circuit area XL is connected to the periphery of the display area AA, so that the circuit area XL is surrounded by the periphery of the display area AA; the packaging dam area FZB is connected to the side of the edge line 11 of the circuit area XL close to the base substrate 1, that is, the packaging dam area FZB is connected to the periphery of the circuit area XL, so that the packaging dam area FZB is surrounded by the periphery of the circuit area XL; the isolation area GL is connected to the side of the edge line 11 of the packaging dam area FZB close to the base substrate 1, that is, the isolation area GL is connected to the periphery of the packaging dam area FZB, so that the isolation area GL is surrounded by the periphery of the packaging dam area FZB; the isolation structure 51 is provided in the isolation area GL.

[0095] In addition, in some other example embodiments of the present disclosure, a PCD (Panel Crack Detection) trace may be provided between the package dam area FZB and the isolation area GL. The PCD trace surrounds the four edges of the package dam area FZB to form a conductor loop. The PCD trace may be used to test whether the crack extends beyond the isolation area GL.

[0096] 2 , in some example embodiments of the present disclosure, a center hole area ZXK is provided on the display panel, and the display area AA may be arranged around the center hole area ZXK. Specifically, the non-display area NA is arranged around the periphery of the center hole area ZXK, and the display area AA is arranged around the periphery of the non-display area NA, so that the non-display area NA is located between the center hole area ZXK and the display area AA. No image is displayed in the center hole area ZXK, and a through hole may be opened in the center hole area ZXK, so that the edge line 11 of the base substrate 1 may be located not only at the outermost side of the display panel, but also inside the display panel, and a camera or other sensor, etc. may be installed in the through hole.

[0097] In this case, the non-display area NA may include the encapsulation dam area FZB and the isolation area GL. The encapsulation dam area FZB is connected to the side of the display area AA near the center hole area ZXK, that is, the display area AA is connected to the periphery of the encapsulation dam area FZB, so that the display area AA is surrounded by the periphery of the encapsulation dam area FZB. The isolation area GL is connected to the side of the encapsulation dam area FZB near the center hole area ZXK, that is, the encapsulation dam area FZB is connected to the periphery of the isolation area GL, so that the encapsulation dam area FZB is surrounded by the periphery of the isolation area GL. In other words, the center hole area ZXK, the isolation area GL, the encapsulation dam area FZB, and the display area AA are connected in sequence from the inside out. The isolation structure 51 is provided in the isolation area GL.

[0098] In addition, it should be noted that when a non-display area NA is provided on the periphery of the display area AA, a center hole area ZXK and a non-display area NA may also be provided inside the display area AA, that is, the structures in FIG. 1 and FIG. 2 may be combined in one example embodiment.

[0099] Of course, the non-display area NA may also include other functional areas, which will not be described one by one here.

[0100] The display panel can be an OLED (Organic Electroluminescence Display) display panel, a QLED (Quantum Dot Light Emitting Diodes) display panel, etc. The display panel has a light-emitting side and a non-light-emitting side, and the light-emitting side and the non-light-emitting side are arranged opposite to each other. The light-emitting side can display a picture, and the side that displays the picture is the display surface.

[0101] The following description will be made using an OLED display panel as an example.

[0102] In this example embodiment, referring to FIG3 and FIG4 , the line area XL and the packaging dam area FZB are omitted in the figures, so that the display area AA is disconnected from the isolation area GL. Therefore, the boundary line that disconnects the display area AA from the isolation area GL is represented by a double-dotted line. The display panel may include a base substrate 1. The material of the base substrate 1 may include an inorganic material. For example, the inorganic material may be glass, quartz, or metal. The material of the base substrate 1 may also include an organic material. For example, the organic material may be a resin material such as polyimide, polycarbonate, polyacrylate, polyetherimide, polyethersulfone, polyethylene terephthalate, and polyethylene naphthalate. The base substrate 1 may be formed of multiple material layers. For example, the base substrate 1 may include multiple base material layers. The material of the base material layer may be any of the above-mentioned materials. Of course, the base substrate 1 may also be set as a single layer and may be any of the above-mentioned materials.

[0103] 3 and 4 , a functional layer group 5 is provided on one side of a base substrate 1. The functional layer group 5 may include a driving substrate 2 and a light-emitting substrate 3. The driving substrate 2 is provided on one side of the base substrate 1, and the light-emitting substrate 3 is provided on a side of the driving substrate 2 facing away from the base substrate 1. The driving substrate 2 may include a plurality of driving circuits arranged in an array, and the light-emitting substrate 3 may include a plurality of light-emitting devices arranged in an array. The driving circuits may drive the light-emitting devices to emit light.

[0104] Specifically, as shown in Figures 3 and 4, a light shielding layer 21 can be provided on one side of the base substrate 1. Light incident from the base substrate 1 into the active layer generates photogenerated carriers in the active layer, which in turn significantly affects the characteristics of the thin-film transistor and ultimately the image quality of the display device. The light shielding layer 21 can block the light incident from the base substrate 1, thereby preventing it from affecting the characteristics of the thin-film transistor and thus the image quality of the display device. Depending on the type of thin-film transistor, the light shielding layer 21 may be omitted.

[0105] A barrier layer 28 may be provided on the side of the light-shielding layer 21 facing away from the base substrate 1, and a buffer layer 22 may be provided on the side of the barrier layer 28 facing away from the base substrate 1. The buffer layer 22 serves to block water vapor and impurity ions in the base substrate 1 (especially the organic material), and serves to add hydrogen ions to the active layer formed subsequently. The buffer layer 22 is made of an insulating material, which can insulate and isolate the light-shielding layer 21 from the active layer. The buffer layer 22 may include silicon nitride, silicon oxide, or silicon oxynitride. Depending on the type of base substrate 1 or process conditions, the buffer layer 22 may be omitted. The barrier layer 28 and the buffer layer 22 may both extend to the non-display area NA.

[0106] An active layer is provided on the side of the buffer layer 22 facing away from the base substrate 1. The active layer may include a channel portion 231 and conductor portions provided at both ends of the channel portion 231. One of the two conductor portions is a source connection portion 232, and the other is a drain connection portion 233. A gate insulating layer 24 is provided on the side of the active layer facing away from the base substrate 1. A gate layer 25 is provided on the side of the gate insulating layer 24 facing away from the base substrate 1. The gate layer 25 may include a gate electrode 251 and a gate line (not shown).

The first connecting conductor layer 27 may include a source electrode 271, a drain electrode 272, and a data line (not shown). The data line may be connected to the source electrode 271, or a portion of the data line may serve as the source electrode 271. The source electrode 271 is connected to the source connection portion 232 through a via in the interlayer dielectric layer 26, and the drain electrode 272 is connected to the drain connection portion 233 through a via in the interlayer dielectric layer 26. The interlayer dielectric layer 26 may extend to the non-display area NA.

Of course, a third connecting conductor layer, a fourth connecting conductor layer, and so on may also be provided as needed. The passivation layer may extend to the non-display area NA.

[0109] 3 and 4 , a planarization layer 29 is provided on the side of the first connection conductor layer 27 facing away from the substrate 1. A via is provided on the planarization layer 29, and the via is connected to the drain 272. The channel portion 231, the gate 251, the source 271, and the drain 272 form a thin film transistor.

[0110] It should be noted that the thin film transistors described in this specification are top-gate thin film transistors. In other exemplary embodiments of the present disclosure, the thin film transistors may also be bottom-gate or dual-gate thin film transistors, and their specific structures are not described in detail here. Moreover, when using thin film transistors with opposite polarities or when the current direction changes during circuit operation, the functions of the "source 271" and "drain 272" are sometimes interchangeable. Therefore, in this specification, the "source 271" and "drain 272" may be interchangeable.

[0111] 3 and 4 , a light-emitting substrate 3 is provided on the side of the planarization layer 29 facing away from the base substrate 1 . The light-emitting substrate 3 may include a first electrode 31 , a pixel definition layer 32 , a light-emitting layer group 33 and a second electrode 34 .

[0112] Specifically, a first electrode 31 is provided on the side of the planarization layer 29 facing away from the base substrate 1. The first electrode 31 is connected to the drain 272 of the driving backplane through a hole. The driving signal is provided to the first electrode 31 through the drain 272. The first electrode 31 can be an anode (pixel electrode).

[0113] A pixel definition layer 32 is provided on the side of the first electrode 31 facing away from the base substrate 1 . An opening is provided on the pixel definition layer 32 , which is connected to the first electrode 31 , so that at least part of the first electrode 31 is not covered by the pixel definition layer 32 .

[0114] A light-emitting layer group 33 is disposed on the side of the pixel definition layer 32 facing away from the substrate 1, with at least a portion of the light-emitting layer group 33 located within the opening. A second electrode 34 is disposed on the side of the light-emitting layer group 33 facing away from the substrate 1. The second electrode 34 can be a cathode (common electrode). Each light-emitting layer group 33 within an opening emits light, forming a sub-pixel 35. The orthographic projection of the sub-pixel 35 on the substrate 1 is the same as the orthographic projection of the light-emitting layer group 33 within the opening on the substrate 1. The display panel can include multiple sub-pixels 35.

[0115] The light-emitting layer group 33 may include a hole injection layer, a hole transport layer, an organic light-emitting layer, an electron transport layer, and an electron injection layer stacked in sequence. The hole injection layer is in contact with the first electrode 31, and the electron injection layer is in contact with the second electrode 34. Of course, in other exemplary embodiments of the present disclosure, the light-emitting layer group 33 may include only the hole transport layer, the light-emitting layer, and the electron transport layer. The light-emitting layer group 33 may also have other structures, and its specific structure can be set as needed.

[0116] Holes are injected into the organic light-emitting layer from the first electrode 31 side, and electrons are injected into the organic light-emitting layer from the second electrode 34 side. Eventually, the holes and electrons recombine in the organic light-emitting layer to generate excitons. When the generated excitons relax from the excited state to the ground state, the OLED emits visible light.

[0117] In this exemplary embodiment, as shown in FIG3 and FIG4 , the display panel may further include an encapsulation layer group 4, which is disposed on the side of the functional layer group 5 facing away from the base substrate 1. For example, the encapsulation layer group 4 may include a first inorganic layer 41, an organic layer 42, and a second inorganic layer 43. The first inorganic layer 41 is disposed on the side of the second electrode 34 facing away from the base substrate 1. The first inorganic layer 41 may be made of silicon nitride (SiNx) or silicon oxynitride (SiNO), etc., and may be formed on the side of the second electrode 34 facing away from the base substrate 1 by chemical vapor deposition (CVD). The organic layer 42 is disposed on the side of the first inorganic layer 41 facing away from the base substrate 1, and may be made of an organic material such as acrylic or epoxy. The second inorganic layer 43 is disposed on the side of the organic layer 42 facing away from the base substrate 1. The second inorganic layer 43 can be made of silicon nitride (SiNx) or silicon oxynitride (SiNO), etc. The second inorganic layer 43 can be formed by chemical vapor deposition (CVD) on the side of the organic layer 42 facing away from the base substrate 1. The encapsulation layer group 4 can encapsulate the light-emitting layer group 33 to isolate it from corrosion caused by water / oxygen in the air.

[0118] As shown in Figure 5, at least two encapsulation dams are provided in the encapsulation dam region FZB. These dams can be arranged in a ring shape, enclosing the circuit region XL. The two encapsulation dams can be a first encapsulation dam 44 and a second encapsulation dam 45. The first encapsulation dam 44 is provided on the side of the second encapsulation dam 45 closer to the circuit region XL, and the height of the first encapsulation dam 44 is less than that of the second encapsulation dam 45. The first inorganic layer 41 extends to the side of the first encapsulation dam 44 closer to the display region AA, the organic layer 42 extends to the side of the second encapsulation dam 45 closer to the display region AA, and the second inorganic layer 43 also extends to the side of the second encapsulation dam 45 closer to the display region AA. The at least two encapsulation dams define the extent of the encapsulation layer group 4. The width of the encapsulation dam region FZB can be less than or equal to 80 microns. For example, the width of the encapsulation dam region FZB can be 60 microns, 62 microns, 65 microns, 67 microns, 70 microns, 73 microns, 75 microns, 78 microns, and so on. Since the package dam region FZB is provided in a ring shape, the width of the package dam region FZB refers to the ring width of the package dam region FZB.

[0119] The driver substrate 2 may be provided with a GOA circuit 201 (Gate Driver On Array, row scanning circuit) in the circuit area XL. The GOA circuit 201 is electrically connected to the thin-film transistors, enabling electrical signal transmission between the thin-film transistors. The width of the circuit area XL is positively correlated with the number of scan rows included in the display panel. If the display panel includes a large number of scan rows, more GOA circuits 201 are required to provide horizontal scanning output, resulting in a wider circuit area XL. Because the circuit area XL is arranged in a ring shape, the width of the circuit area XL refers to the width of the ring of the circuit area XL.

[0120] The width of the isolation region GL may be greater than or equal to 40 micrometers and less than or equal to 70 micrometers. For example, the width of the isolation region GL may be 43 micrometers, 45 micrometers, 48 ​​micrometers, 50 micrometers, 52 micrometers, 55 micrometers, 57 micrometers, 60 micrometers, 63 micrometers, 65 micrometers, 68 micrometers, etc. Since the isolation region GL is provided in a ring shape, the width of the isolation region GL refers to the ring width of the isolation region GL.

[0121] Both the package dam area FZB and the isolation area GL relate to the width of the display device's outer frame. While ensuring process feasibility, functionality, and reliability, the narrower the width, the better. The above numerical range represents the width achievable under current process conditions. With further improvements in process equipment, this range could be further reduced.

[0122] The isolation structure 51 is located in the non-display area NA. Specifically, the isolation structure 51 is located in the isolation area GL.

[0123] In this exemplary embodiment, at least one circle of isolation structure 51 is provided on the functional layer group 5 . For example, one circle, two circles, or multiple circles of isolation structure 51 may be provided on the functional layer group 5 .

[0124] Specifically, as shown in Figures 3 and 4, the isolation structure 51 can be provided on at least a portion of the insulating layer extending from the drive substrate 2 to the non-display area NA. For example, the isolation structure 51 can be provided on the blocking layer 28, the buffer layer 22, the gate insulating layer 24 and the interlayer dielectric layer 26. When the insulating layers extending from the driving substrate 2 to the non-display area NA are all inorganic film layers, the isolation structure 51 is formed on these inorganic film layers; when the insulating layers extending from the driving substrate 2 to the non-display area NA include both inorganic film layers and organic film layers, the isolation structure 51 is formed on these inorganic film layers and organic film layers; when the organic film layer is arranged on the side of the multi-layer inorganic film layer close to the base substrate 1 or on the side away from the base substrate 1, the isolation structure 51 may not be formed on the organic film layer; when the organic film layer is arranged between two inorganic film layers, in order to facilitate the preparation process and reduce costs, the isolation structure 51 can be formed on the organic film layer; and the isolation structure 51 can occupy the entire thickness of the inorganic film layer closest to the base substrate 1, or it can occupy a part of the thickness of the inorganic film layer closest to the base substrate 1; therefore, under normal circumstances, the isolation structure 51 is formed on all inorganic film layers, and the isolation structure 51 makes it difficult for the inorganic film layer of the inorganic material to crack, and water / oxygen in the air will not corrode the luminescent material through the cracks, and will not form growing black spots that continue to grow.

[0125] The isolation structure 51 can be planarized by the planarization layer 29 , facilitating the arrangement of subsequent film layers.

[0126] Of course, in other exemplary embodiments of the present disclosure, when the insulating layer extending from the drive substrate 2 to the non-display area NA is different, the film layer forming the isolation structure 51 may also be different, which will not be described here. Furthermore, when the insulating layer extending from the light-emitting substrate 3 to the non-display area NA includes an inorganic film layer, the isolation structure 51 may also be provided on the inorganic film layer extending from the light-emitting substrate 3 to the non-display area NA.

[0127] 6 and 17 to 27, the line area XL and the package dam area FZB are omitted in FIG6 and 18 to 23. The isolation structure 51 may include a plurality of isolation rings 511, and the orthographic projection of the isolation ring 511 on the base substrate 1 is set to be annular. It should be noted that the ring not only includes circular rings, but also includes various regular or irregular non-circular rings. As long as a closed structure is formed, it is considered to be annular. As shown in FIG7, after the display panel is hit, the plurality of isolation rings 511 of at least one circle of the isolation structure 51 can disperse the collision force multiple times, making it less likely for the display panel to crack, preventing water / oxygen in the air from corroding the luminescent material through the cracks, and preventing the formation of continuously growing black spots.

[0128] Specifically, as shown in Figures 7 and 8, the isolation ring 511 may include a first curved portion 5111 and a second curved portion 5112. The first curved portion 5111 has a first endpoint A and a second endpoint B that are oppositely disposed. The line connecting the first endpoint A and the second endpoint B is parallel to the edge line 11 of the substrate 1 closest to the first curved portion 5111. This ensures that the extension direction of the first curved portion 5111 is parallel to the edge line 11 of the substrate 1 closest to the first curved portion 5111. Generally, collision forces are transmitted from the edge of the display panel. The first curved portion 5111 can disperse the collision forces into smaller components in multiple directions, thereby preventing a large collision force from concentrating in one location and direction. This makes the display panel less prone to cracks, prevents water and oxygen in the air from eroding the luminescent material through the cracks, and prevents the formation of continuously growing black spots.

[0129] The second arc-shaped portion 5112 has a third endpoint C and a fourth endpoint D that are relatively arranged. The connecting line between the third endpoint C and the fourth endpoint D is parallel to the edge line 11 of the base substrate 1 that is closest to the second arc-shaped portion 5112, so that the extension direction of the second arc-shaped portion 5112 is parallel to the edge line 11 of the base substrate 1 that is closest to the second arc-shaped portion 5112. In other words, the extension direction of the second arc-shaped portion 5112 is consistent with the extension direction of the first arc-shaped portion 5111.

[0130] It should be noted that, when the isolation structure 51 is arranged in the circular isolation area GL, for example, as shown in Figure 17, when the isolation structure 51 is arranged around the periphery of the circular center hole area ZXK, the edge line of the center hole area ZXK is the edge line 11 of the substrate 1, and the connecting line between the first endpoint A and the second endpoint B is parallel to the tangent of the edge line 11 of the substrate 1 closest to the first arc portion 5111. Similarly, the connecting line between the third endpoint C and the fourth endpoint D is parallel to the tangent of the edge line 11 of the substrate 1 closest to the second arc portion 5112.

[0131] Moreover, the second arc-shaped portion 5112 is connected to the first arc-shaped portion 5111; specifically, as shown in Figure 9, the second arc-shaped portion 5112 can be directly connected to the first arc-shaped portion 5111, that is, the third endpoint C is connected to the first endpoint A, so that the third endpoint C and the first endpoint A form an endpoint; the fourth endpoint D is connected to the second endpoint B, so that the fourth endpoint D and the second endpoint B form an endpoint.

[0132] In this way, a part of the force component dispersed by the first arc-shaped portion 5111 will be transmitted to the end of the second arc-shaped portion 5112 connected thereto, and the end of the second arc-shaped portion 5112 will disperse the force component again and absorb it to a certain extent; another part of the force component dispersed by the first arc-shaped portion 5111 will be transmitted to the middle part of the second arc-shaped portion 5112, and the middle part of the second arc-shaped portion 5112 will disperse the force component again and absorb it to a certain extent.

[0133] Moreover, the second arc portion 5112 is arranged opposite to the first arc portion 5111, and the bending direction of the second arc portion 5112 is opposite to that of the first arc portion 5111. For example, referring to Figures 7 and 8, the first arc portion 5111 is arranged on the side of the second arc portion 5112 away from the display area AA, so that the first arc portion 5111 is closer to the edge line 11 of the display panel than the second arc portion 5112; the first arc portion 5111 can protrude toward the side close to the display area AA, so that when the first arc portion 5111 is set to a circular arc shape, the center of the first arc portion 5111 is located on the side of the first arc portion 5111 close to the edge line 11 of the display panel; the second arc portion 5112 can protrude toward the side close to the edge line 11 of the display panel, so that when the second arc portion 5112 is set to a circular arc shape, the center of the second arc portion 5112 is located on the side of the second arc portion 5112 close to the display area AA.

[0134] Of course, in some other example embodiments of the present disclosure, as shown in FIG9 , the first arc portion 5111 may protrude toward the side close to the edge line 11 of the display panel, so that when the first arc portion 5111 is set to a circular arc shape, the center of the first arc portion 5111 is located on the side of the first arc portion 5111 close to the display area AA; and the second arc portion 5112 may protrude toward the side close to the display area AA, so that when the second arc portion 5112 is set to a circular arc shape, the center of the second arc portion 5112 is located on the side of the second arc portion 5112 close to the edge line 11 of the display panel.

[0135] Such a configuration makes the dispersion direction of the component force of the second arc portion 5112 opposite to the dispersion direction of the collision force of the first arc portion 5111, further reducing the impact of the collision force on the display panel, so that the display panel will not produce cracks, preventing water / oxygen in the air from corroding the luminescent material through the cracks, and preventing the formation of continuously growing black spots.

[0136] Of course, in some other exemplary embodiments of the present disclosure, as shown in FIG7 and FIG8 , the isolation ring 511 may further include a first connecting portion 5113 and a second connecting portion 5114; the first connecting portion 5113 is connected between the first endpoint A and the third endpoint C; and the second connecting portion 5114 is connected between the second endpoint B and the fourth endpoint D. The first connecting portion 5113 and the second connecting portion 5114 indirectly connect the second arc-shaped portion 5112 to the first arc-shaped portion 5111.

[0137] With such a configuration, a portion of the force component dispersed by the first arc-shaped portion 5111 will be transmitted to the first connecting portion 5113 and the second connecting portion 5114 connected thereto. The first connecting portion 5113 and the second connecting portion 5114 will disperse and absorb the force component to a certain extent, and then transmit the force component to the second arc-shaped portion 5112 for dispersion and absorption to a certain extent, thereby further reducing the impact of the collision force on the display panel, preventing cracks from occurring in the display panel, and preventing water / oxygen in the air from corroding the luminescent material through the cracks, and preventing the formation of continuously growing black spots.

[0138] Specifically, the first connection portion 5113 can be set to an arc or a ring, and the second connection portion 5114 can also be set to an arc or a ring. For example, with reference to Figures 7, 10 and 11, the first connection portion 5113 can be set to a circular arc, an elliptical arc, a circular ring, an elliptical ring, etc., and the second connection portion 5114 can also be set to a circular arc, an elliptical arc, a circular ring, an elliptical ring, etc. The arc-shaped or ring-shaped first connection portion 5113 and the second connection portion 5114 can more effectively disperse and absorb the component forces, so that the impact of the collision force on the display panel is almost reduced to zero. The shape of the first connection portion 5113 and the shape of the second connection portion 5114 can be the same or different. Of course, in some other example embodiments of the present disclosure, with reference to Figure 12, the first connection portion 5113 can be set to a straight line, and the second connection portion 5114 can also be set to a straight line.

[0139] The radius of curvature of the first arc portion 5111 may be equal to the radius of curvature of the second arc portion 5112, and the radius of curvature of the first connecting portion 5113 may be equal to the radius of curvature of the second connecting portion 5114. The radius of curvature of the first arc portion 5111 is greater than the radius of curvature of the first connecting portion 5113, that is, the radii of curvature of the first arc portion 5111 and the second arc portion 5112 are greater than the radii of curvature of the first connecting portion 5113 and the second connecting portion 5114. This makes the curvature of the first arc portion 5111 and the second arc portion 5112 relatively gentle, and the angle of dispersion of the collision force is larger, which is more conducive to dispersing the collision force.

[0140] Of course, in some other example embodiments of the present disclosure, the radius of curvature of the first arc portion 5111 may be different from the radius of curvature of the second arc portion 5112, the radius of curvature of the first connection portion 5113 may be different from the radius of curvature of the second connection portion 5114, and the radius of curvature of the first arc portion 5111 and the second arc portion 5112 may be equal to the radius of curvature of the first connection portion 5113 and the second connection portion 5114.

[0141] Specifically, the radius of curvature of the first connecting portion 5113 and the radius of curvature of the second connecting portion 5114 are greater than or equal to 7.5 microns. For example, the radius of curvature of the first connecting portion 5113 and the radius of curvature of the second connecting portion 5114 can be 8 microns, 8.5 microns, 9 microns, 9.5 microns, 10 microns, etc.; so that the radius of curvature of the first arc portion 5111 and the radius of curvature of the second arc portion 5112 are also greater than or equal to 7.5 microns. For example, the radius of curvature of the first arc portion 5111 and the radius of curvature of the second arc portion 5112 can be 8 microns, 8.5 microns, 9 microns, 9.5 microns, 10 microns, etc.

[0142] It should be noted that since the first arc-shaped portion 5111, the second arc-shaped portion 5112, the first connecting portion 5113 and the second connecting portion 5114 all have a certain thickness, the curvature radius of the two side surfaces in the thickness direction is different, and the curvature radius of the inner side surface is smaller than the curvature radius of the outer side surface. The above-mentioned curvature radii all refer to smaller curvature radii.

[0143] Furthermore, the extended length of the first curved portion 5111 can be equal to the extended length of the second curved portion 5112, the extended length of the first connecting portion 5113 can be equal to the extended length of the second connecting portion 5114, and the extended lengths of the first curved portion 5111 and the second curved portion 5112 can be greater than the extended lengths of the first connecting portion 5113 and the second connecting portion 5114. Since the first curved portion 5111 directly receives the collision force, setting the extended length of the first curved portion 5111 longer allows the first curved portion 5111 to have better cushioning performance and absorb more collision force.

[0144] The minimum distance between the first connecting portion 5113 and the second connecting portion 5114 is greater than or equal to the minimum distance between the first curved portion 5111 and the second curved portion 5112, and the maximum distance between the first connecting portion 5113 and the second connecting portion 5114 is greater than or equal to the maximum distance between the first curved portion 5111 and the second curved portion 5112. This configuration allows the isolation ring 511 to be formed into an elongated strip, allowing for more turns of the isolation structure 51 to be disposed within an isolation region GL of the same width.

[0145] Specifically, the minimum spacing between the first arc portion 5111 and the second arc portion 5112 is greater than or equal to 5 microns. For example, the minimum spacing between the first arc portion 5111 and the second arc portion 5112 can be 5.5 microns, 6 microns, 6.5 microns, 7 microns, 7.5 microns, 8 microns, etc.; so that the minimum spacing between the first connection portion 5113 and the second connection portion 5114 is also greater than or equal to 5 microns. For example, the minimum spacing between the first connection portion 5113 and the second connection portion 5114 can be 5.5 microns, 6 microns, 6.5 microns, 7 microns, 7.5 microns, 8 microns, etc.

[0146] The width of the first arc portion 5111, the second arc portion 5112, the first connecting portion 5113 and the second connecting portion 5114 is greater than or equal to 5 microns. For example, the width of the first arc portion 5111, the second arc portion 5112, the first connecting portion 5113 and the second connecting portion 5114 can be 5.5 microns, 6 microns, 6.5 microns, 7 microns, 7.5 microns, 8 microns, etc.

[0147] It should be noted that the above numerical range is for illustration only and is a numerical range with a high cost performance that can be achieved under current process conditions. The above numerical range can be adjusted according to needs and improvements in process equipment.

[0148] As shown in Figure 4, the isolation ring 511 can be a protruding structure formed on the insulating film layer of the functional layer group 5 extending to the non-display area NA, that is, the first arc portion 5111, the second arc portion 5112, the first connecting portion 5113 and the second connecting portion 5114 can be a protruding structure formed on the functional layer group 5, that is, the insulating film layer extending from the functional layer group 5 to the isolation area GL is etched to form the first arc portion 5111, the second arc portion 5112, the first connecting portion 5113 and the second connecting portion 5114, so that the other parts except the first arc portion 5111, the second arc portion 5112, the first connecting portion 5113 and the second connecting portion 5114 form a recessed structure 512, and the buffer structure 513 is filled in the recessed structure 512. Specifically, a part of the planarization layer 29 can be formed in the recessed structure 512, and the material of the planarization layer 29 is a buffer material. Of course, the recessed structure 512 may also be filled with a buffer material. The buffer material may be a substance with a buffering effect, such as acrylic glue (Touch Organic, TOC), UV curing glue, and other organic materials.

[0149] Of course, in some other exemplary embodiments of the present disclosure, as shown in FIG3 , the isolation ring 511 may be a groove formed in the insulating film extending from the functional layer group 5 to the non-display area NA. That is, the first curved portion 5111, the second curved portion 5112, the first connecting portion 5113, and the second connecting portion 5114 may be grooves provided on the functional layer group 5. Specifically, the insulating film extending from the functional layer group 5 to the isolation area GL is etched to form the first curved portion 5111, the second curved portion 5112, the first connecting portion 5113, and the second connecting portion 5114, so that the remaining portions except the first curved portion 5111, the second curved portion 5112, the first connecting portion 5113, and the second connecting portion 5114 form protrusions. The buffer structure 513 is filled within the isolation ring 511, that is, the buffer structure 513 is filled within the groove. Specifically, the buffer structure 513 may be a portion of the planarization layer 29 formed within the isolation ring 511. The planarization layer 29 is made of a buffer material. Of course, the groove may also be filled with a buffer material alone. The buffer material may be a substance with a buffering effect, such as acrylic glue (Touch Organic, TOC), UV curing glue, and other organic materials.

[0150] The specific material of the buffer structure 513 is not particularly limited; generally, the buffer structure 513 can be made of a material with an elastic modulus less than that of the insulating film extending from the functional layer group 5 to the isolation region GL. The buffer structure 513 can absorb some of the impact force, preventing the display panel from cracking due to the impact. It also prevents water and oxygen in the air from corroding the luminescent material through the cracks, preventing the formation of growing dark spots.

[0151] 13 to 16 , in some exemplary embodiments of the present disclosure, the isolation structure 51 may further include an auxiliary portion 514 disposed within the isolation ring 511 .

[0152] For example, as shown in Figure 13, the auxiliary portion 514 is set to be long and parallel to the connecting line between the first endpoint A and the second endpoint B, that is, the extending direction of the auxiliary portion 514 is substantially consistent with the extending direction of the first arc-shaped portion 5111.

[0153] The long strip-shaped auxiliary parts 514 are arranged in multiple parallel parts. For example, the auxiliary parts 514 may include a first auxiliary part, a second auxiliary part and a third auxiliary part; the first auxiliary part, the second auxiliary part and the third auxiliary part are arranged parallel to each other; the first auxiliary part is connected from the first arc part 5111 to the first connection part 5113 or the second connection part 5114; the second auxiliary part is connected from the second arc part 5112 to the first connection part 5113 or the second connection part 5114; the third auxiliary part is connected from the first connection part 5113 to the second connection part 5114.

[0154] As shown in Figure 14, the long strip-shaped auxiliary part 514 may include at least two sub-auxiliary parts 5141 set at intervals. For example, the first auxiliary part, the second auxiliary part and the third auxiliary part each include at least two sub-auxiliary parts 5141 set at intervals, that is, the first auxiliary part, the second auxiliary part and the third auxiliary part are set as at least two disconnected sub-auxiliary parts 5141.

[0155] Of course, in some other exemplary embodiments of the present disclosure, as shown in Figures 15 and 16 , the auxiliary portion 514 can be configured as a dot. For example, as shown in Figure 16 , the auxiliary portion 514 can be configured as a circle. In this case, the diameter of the auxiliary portion 514 is less than or equal to the minimum distance between the first arc-shaped portion 5111 and the second arc-shaped portion 5112, so that at least one auxiliary portion 514 can also be provided at the minimum distance between the first arc-shaped portion 5111 and the second arc-shaped portion 5112. The auxiliary portion 514 can also be configured as various regular polygons, crosses, etc., which are not described here one by one.

[0156] As shown in FIG4 , the auxiliary portion 514 may be a protruding structure formed on the insulating film layer extending from the functional layer group 5 to the non-display area NA. Specifically, the insulating film layer extending from the functional layer group 5 to the isolation area GL is etched to form the protruding auxiliary portion 514, so that the portion other than the auxiliary portion 514 forms a recessed structure 512. The recessed structure 512 surrounds the auxiliary portion 514, and a buffer structure 513 is filled within the recessed structure 512. Specifically, a portion of the planarization layer 29 may be formed within the recessed structure 512, and the material of the planarization layer 29 is a buffer material. Of course, a buffer material may also be separately filled within the recessed structure 512. The buffer material may be a substance having a buffering effect, such as acrylic glue (Touch Organic, TOC), UV curing glue, or other organic materials.

[0157] Of course, in some other example embodiments of the present disclosure, the auxiliary portion 514 can be a groove formed in the insulating film layer extending from the functional layer group 5 to the non-display area NA, that is, the insulating film layer extending from the functional layer group 5 to the isolation area GL is etched to form an auxiliary portion 514 with a groove structure, so that the other parts except the auxiliary portion 514 form a protrusion. The buffer structure 513 is filled in the auxiliary portion 514, that is, the buffer structure 513 is filled in the groove. Specifically, a portion of the planarization layer 29 can be formed in the auxiliary portion 514, and the material of the planarization layer 29 is a buffer material. Of course, the buffer material can also be filled in the auxiliary portion 514 alone. The buffer material can be a substance with a buffering effect, such as acrylic glue (Touch Organic, TOC), UV curing glue and other organic materials.

[0158] The specific material of the buffer structure 513 is not particularly limited; generally, the buffer structure 513 can be made of a material with an elastic modulus less than that of the insulating film extending from the functional layer group 5 to the isolation region GL. The buffer structure 513 can absorb some of the impact force, preventing the display panel from cracking due to the impact. It also prevents water and oxygen in the air from corroding the luminescent material through the cracks, preventing the formation of growing dark spots.

[0159] In addition, it should be noted that when the isolation ring 511 is a protruding structure, the auxiliary portion 514 is generally also a protruding structure; conversely, when the isolation ring 511 is a recessed structure, the auxiliary portion 514 is generally also a recessed structure. Of course, in other exemplary embodiments of the present disclosure, the isolation ring 511 may be a protruding structure and the auxiliary portion 514 may be a recessed structure; conversely, the isolation ring 511 may be a recessed structure and the auxiliary portion 514 may be a protruding structure.

[0160] Furthermore, when the isolation ring 511 is a protruding structure formed on the insulating film layer extending from the functional layer group 5 to the non-display area NA, and the auxiliary portion 514 is also a protruding structure formed on the insulating film layer extending from the functional layer group 5 to the non-display area NA, that is, when both the isolation ring 511 and the auxiliary portion 514 are protruding structures, the auxiliary portion 514 is spaced apart from the isolation ring 511 in the second direction Y, and the second direction Y is perpendicular to the line connecting the first endpoint A and the second endpoint B. This allows the auxiliary portion 514 to further disperse the impact force passing through the first arc-shaped portion 5111. Furthermore, the auxiliary portion 514 is spaced apart from the isolation ring 511 in the second direction Y. Even if the auxiliary portion 514 is cracked due to stress, the crack will not extend to the isolation ring 511. Alternatively, even if the isolation ring 511 is cracked due to stress, the crack will not extend to the auxiliary portion 514.

[0161] The specific structures of the isolation rings 511 are described in detail above. The layout structures of the isolation rings 511 and the isolation structure 51 are described below. The isolation rings 511 of the above structures are all applicable to the following layout structure.

[0162] In some exemplary embodiments of the present disclosure, as shown in FIG6 , the isolation structure 51 can be provided as a ring, specifically surrounding the package dam area FZB; and as shown in FIG17 , the isolation structure 51 can be provided as a ring surrounding the center hole area ZXK. Adjacent isolation rings 511 are interconnected, i.e., a ring of isolation structures 51 comprises multiple isolation rings 511 connected end-to-end to form a seamless ring structure. This ensures that no matter where the display panel is impacted, the impact force is isolated by the isolation structure 51, without affecting the display quality of the display area AA.

[0163] In some example embodiments of the present disclosure, referring to Figures 18 to 27, the isolation structure 51 is set to at least two circles. For example, the isolation structure 51 can be set to two circles, three circles or more circles around the packaging dam area FZB, and the isolation structure 51 can also be set to two circles, three circles or more circles around the center hole area ZXK.

[0164] Adjacent isolation rings 511 of at least one circle of isolation structure 51 are interconnected. For example, adjacent isolation rings 511 of one, two, or more circles of isolation structure 51 closest to display area AA may be interconnected, or adjacent isolation rings 511 of one, two, or more circles of isolation structure 51 farthest from display area AA may be interconnected, or adjacent isolation rings 511 of one, two, or more circles of isolation structure 51 located in the middle may be interconnected. This configuration allows at least one circle of isolation structure 51 to form a ring-shaped structure without breaks. Therefore, no matter where the display panel is impacted, the impact force is isolated by the isolation structure 51. Furthermore, the at least two circles of isolation structure 51 can disperse the impact force multiple times, reducing the impact force to almost zero, and preventing cracks in the display panel.

[0165] In some exemplary embodiments of the present disclosure, as shown in Figures 18-21 , when the display panel is configured as a rectangle or various polygons, the isolation region GL disposed on the periphery of the display area AA is configured as a rectangle or various polygons in an annular shape. The isolation region GL includes a linearly extending sub-isolation region ZGL, and the isolation rings 511 within the sub-isolation region ZGL, belonging to the same isolation structure 51, can be arranged in a row. Of course, when the center hole region ZXK is configured as a rectangle or various polygons, the isolation region GL disposed between the center hole region ZXK and the display area AA is configured as a rectangle or various polygons in an annular shape.

[0166] In this case, the isolation structure 51 can be provided as at least two turns. For example, the isolation structure 51 can be provided as two, three, or more turns around the package dam area FZB. The isolation structure 51 can also be provided as two, three, or more turns around the center hole area ZXK. Referring to Figures 18-21, two adjacent isolation rings 511 belonging to the same isolation structure 51 and located in the same row are interconnected. That is, at least two isolation rings 511 in a row are sequentially connected to form a row of isolation strips 51T without breaks, so that one isolation structure 51 can include four isolation strips 51T.

[0167] Furthermore, as shown in Figures 18 and 19, the isolation rings 511 included in two adjacent circles of isolation structures 51 can be staggered. For example, a two-circle isolation structure 51 is provided. The outer circle is the first isolation structure 51a, which can include multiple first isolation rings 51a1. The inner circle is the second isolation structure 51b, which can include multiple second isolation rings 51b1. If multiple first isolation rings 51a1 in a row are connected, the second isolation ring 51b1 can be positioned opposite the connection between two adjacent first isolation rings 51a1, thereby staggering the isolation rings 511 included in the two adjacent circles of isolation structures 51. This ensures that no matter where the display panel is impacted, the impact force is isolated by the isolation structure 51. Furthermore, the connection between two adjacent first isolation rings 51a1 is a weak point, and the impact force is transmitted through the weak point to the second isolation ring 51b1, where it is further dispersed, reducing the impact force to almost zero and preventing cracks in the display panel. In this case, the first isolation structure 51a located in the outer circle may include four first isolation strips, and the second isolation structure 51b located in the inner circle may include four second isolation strips. The length of the first isolation strip may also be greater than the length of the second isolation strip directly opposite to the first isolation strip, so that the first isolation structure 51a located in the outer circle can also fill and distribute the corners of the display panel, which can better offset stress and prevent cracks.

[0168] Of course, in some other exemplary embodiments of the present disclosure, as shown in Figures 20 and 21, the isolation rings 511 included in two adjacent isolation structures 51 can also be arranged opposite each other. In this case, the first isolation structure 51a located in the outer ring can include four first isolation bars, and the second isolation structure 51b located in the inner ring can include four second isolation bars. The first isolation bars and the opposite second isolation bars can be the same length, or the length of the first isolation bar can be greater than the length of the second isolation bar directly opposite the first isolation bar, so that the first isolation structure 51a located in the outer ring can also fill and distribute the corners of the display panel, better offsetting stress and preventing cracks.

[0169] In some example embodiments of the present disclosure, the isolation structure 51 is configured to have at least two circles. For example, referring to Figures 22 and 23 , the isolation structure 51 may be configured to have two, three, or more circles around the packaging dam area FZB. Referring to Figures 24 and 25 , the isolation structure 51 may also be configured to have two, three, or more circles around the center hole area ZXK.

[0170] As shown in Figures 22-25 , the isolation rings 511 included in each circle of isolation structure 51 are spaced apart, meaning that the isolation rings 511 within a single isolation structure 51 are spaced apart so that no two adjacent isolation rings 511 are connected. The isolation rings 511 within two adjacent circles of isolation structure 51 are staggered. For illustration, the outer circle comprises the first isolation structure 51a, which includes multiple first isolation rings 51a1, with first spacers 51a2 positioned between adjacent first isolation rings 51a1. The inner circle comprises the second isolation structure 51b, which includes multiple second isolation rings 51b1, with second spacers 51b2 positioned between adjacent second isolation rings 51b1. The second isolation rings 51b1 are positioned opposite the first spacers 51a2, and vice versa. The first isolation structure 51a and the second isolation structure 51b effectively form an uninterrupted isolation zone, preventing water / oxygen from entering the display area AA from the discontinuous first spacer 51a2 and the second spacer 51b2, thereby preventing the luminescent material from being corroded by water / oxygen in the air.

[0171] Moreover, in this case, the length of the first isolation structure 51a located in the outer circle can be greater than the length of the second isolation structure 51b located in the inner circle, so that the first isolation structure 51a located in the outer circle can also be filled and distributed at the corners of the display panel, which can better offset stress and prevent cracks.

[0172] In some example embodiments of the present disclosure, referring to Figures 24 to 26, the isolation structure 51 is set to at least two circles. For example, the isolation structure 51 can be set to two circles, three circles or more circles around the packaging dam area FZB, and the isolation structure 51 can also be set to two circles, three circles or more circles around the center hole area ZXK.

[0173] The size of the isolation ring 511 can increase as the linear distance between the isolation structure 51 and the outermost edge line 11 of the base substrate 1 decreases, that is, the size of the isolation ring 511 decreases as it approaches the center of the display panel. The outermost edge line 11 of the base substrate 1 refers to the edge line 11 of the base substrate 1 surrounding the outermost periphery of the non-display area NA. As shown in Figure 13, the size of the isolation ring 511 refers to the length and width of the isolation ring 511. The length of the isolation ring 511 refers to the maximum dimension of the isolation ring 511 in the first direction X, and the width of the isolation ring 511 refers to the maximum dimension of the isolation ring 511 in the second direction Y. The first direction X is parallel to the connecting line between the first endpoint A and the second endpoint B, and the second direction Y is perpendicular to the first direction X. Therefore, the first direction X and the second direction Y rotate as the isolation ring 511 rotates.

[0174] Since the closer to the center of the display panel, the smaller the length and width or diameter of the isolation area GL, the size of the isolation ring 511 is set to be smaller, so that the isolation structure 51 located in the inner circle can include more isolation rings 511, especially in the annular isolation area GL set between the center hole area ZXK and the display area AA. Since the shape of the isolation ring 511 does not quite match the annular isolation area GL, if the size of the isolation ring 511 is set to be larger, it is impossible to set more isolation rings 511, nor can more circles of isolation structures 51 be set, which can easily lead to the formation of larger spacers between the isolation rings 511, and water / oxygen can easily enter the display area AA from the spacers, causing the luminescent material to be corroded by water / oxygen in the air.

[0175] Of course, in some other exemplary embodiments of the present disclosure, the size of the isolation ring 511 may also decrease as the linear distance between the isolation structure 51 and the outermost edge line 11 of the base substrate 1 decreases. That is, the closer the isolation ring 511 is to the outermost edge line 11 of the base substrate 1, the smaller the size. This allows the isolation structure 51 closer to the outermost edge line 11 of the base substrate 1 to include more isolation rings 511, thereby ensuring the strength of the display panel, absorbing more impact force, and preventing cracks.

[0176] In some further exemplary embodiments of the present disclosure, the isolation structure 51 may include a first isolation structure 51a and a second isolation structure 51b. The first isolation structure 51a may include a first isolation ring 51a1, and the second isolation structure 51b may include a second isolation ring 51b1. The size of the second isolation ring 51b1 is larger than the size of the first isolation ring 51a1. For example, the length of the second isolation ring 51b1 may be greater than the length of the first isolation ring 51a1; the width of the second isolation ring 51b1 may be greater than the width of the first isolation ring 51a1; or the length of the second isolation ring 51b1 may be greater than the length of the first isolation ring 51a1, and the width of the second isolation ring 51b1 may be greater than the width of the first isolation ring 51a1. The first isolation structures 51a and the second isolation structures 51b are arranged alternately.

[0177] In some example embodiments of the present disclosure, the isolation structure 51 may include a first isolation structure 51a and a second isolation structure 51b. The first isolation structure 51a may include a first isolation ring 51a1, with a first spacer 51a2 disposed between two adjacent first isolation rings 51a1. Specifically, the first isolation rings 51a1 of the first isolation structure 51a are spaced apart. The sum of the lengths of the first isolation rings 51a1 in the first direction X and the lengths of the first spacer 51a2 in the first direction X is a first distance. The second isolation structure 51b may include a second isolation ring 51b1, with a second spacer 51b2 disposed between two adjacent second isolation rings 51b1. Specifically, the sum of the lengths of the second isolation rings 51b1 in the first direction X and the lengths of the second spacer 51b2 in the first direction X is a second distance. The second isolation ring 51b1 is larger than the first isolation ring 51a1.

[0178] When the isolation region GL is configured as a ring, the circumference of the ring is a common multiple of the first distance and the second distance. For example, if the first distance is 10 microns and the second distance is 15 microns, the circumference of the ring can be 30 microns, 60 microns, 90 microns, 120 microns, 150 microns, and so on.

[0179] When the isolation region GL includes a plurality of sequentially connected straight strip-shaped sub-isolation regions ZGL, the length of the sub-isolation region ZGL is a common multiple of the first distance between the first isolation structure 51a and the second distance between the second isolation structure 51b. For example, if the first distance is 10 microns and the second distance is 15 microns, the length of the sub-isolation region ZGL can be 30 microns, 60 microns, 90 microns, 120 microns, 150 microns, and so on.

[0180] Such an arrangement can ensure that adjacent isolation structures 51 are complementary at any position and do not experience a complete disconnection.

[0181] Furthermore, in the above exemplary embodiment, when two adjacent isolation rings 511 are spaced apart, the spacing between the two adjacent isolation rings 511 is the same, that is, the multiple isolation rings 511 of an isolation structure 51 can be arranged at equal intervals. Of course, as needed, the multiple isolation rings 511 of an isolation structure 51 can also be arranged at unequal intervals, or the multiple isolation rings 511 of a portion of an isolation structure 51 can be arranged at equal intervals, while the multiple isolation rings 511 of another portion of the isolation structure 51 can be arranged at unequal intervals.

[0182] In some exemplary embodiments of the present disclosure, as shown in Figures 6 and 17-27, an annular isolation trench 515 is provided on the drive substrate 2. The annular isolation trench 515 is located in the non-display area NA, specifically in the isolation area GL. It is located on the side of the isolation structure 51 closest to the display area AA. Specifically, when the isolation area GL is located outside the display area AA, the annular isolation trench 515 surrounds the package dam area FZB; when the isolation area GL is located outside the center hole area ZXK, the annular isolation trench 515 surrounds the isolation structure 51. A portion of the planarization layer 29 fills the annular isolation trench 515. The isolation trench 515 further absorbs and disperses impact forces, preventing cracks in the display panel and preventing water / oxygen in the air from eroding the luminescent material through the cracks, thereby preventing the formation of continuously growing dark spots. Furthermore, the isolation trench 515 is continuous, fully blocking impact forces passing through the isolation structure 51.

[0183] It should be noted that the size of the central hole area ZXK shown in FIG. 17 and FIG. 24 to FIG. 27 is somewhat enlarged relative to the proportion of the entire display panel, and in actual design and application, it accounts for a relatively small proportion in the display panel.

[0184] A second planarization layer 6 is further provided on the side of the encapsulation layer group 4 facing away from the base substrate 1, and a protective layer 7 is further provided on the side of the second planarization layer 6 facing away from the base substrate 1. Of course, the display panel may also include other film layers, which are not described here one by one.

[0185] Based on the same inventive concept, an exemplary embodiment of the present disclosure provides a display device, which may include any of the display panels described above. The specific structure of the display panel has been described in detail above, so it will not be repeated here.

[0186] The specific type of the display device is not particularly limited, and any type of display device commonly used in the field can be used, such as mobile devices such as mobile phones, wearable devices such as watches, VR devices, etc. Those skilled in the art can make corresponding choices based on the specific purpose of the display device, which will not be elaborated here.

[0187] It should be noted that, in addition to the display panel, the display device also includes other necessary components and components, such as the housing, circuit board, power cord, etc. Taking the display as an example, technical personnel in this field can make corresponding supplements based on the specific usage requirements of the display device, which will not be repeated here.
