[0057] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0059] In an organic display panel, a light-emitting functional layer is usually provided, and a plurality of light-emitting structures are provided in the light-emitting functional layer. Among them, the light-emitting structure is usually prepared by evaporation. Furthermore, in order to reduce the preparation cost of the light-emitting structure, in some embodiments, the display panel is also provided with an isolation structure. The existence of the isolation structure can make the light-emitting material not need a fine metal mask plate during the preparation of the light-emitting structure, but the light-emitting material at some positions is removed by evaporation of the entire surface and then etching. This can reduce the cost of structures such as the mask plate required in the preparation of the light-emitting structure.

[0060] However, in the display panel mentioned above, the presence of the isolation structure will cause the transmittance of at least part of the display panel to be too low, which cannot meet the needs of using the transparent display panel and the needs of photosensitive functions such as under-screen camera.

[0061] In view of this, on the one hand, see Figures 1 to 3 An embodiment of the present application provides a display panel, which includes a substrate 10, an isolation structure 20 and a light-emitting functional layer 30. The isolation structure 20 is arranged on one side of the substrate 10. The isolation structure 20 encloses a plurality of opening structures 22, and light-transmitting openings 23 are formed between the isolation structures 20. The light-transmitting openings 23 are spaced apart from the opening structures 22.

[0062] The substrate 10 mainly plays a supporting and bearing role, and other film layers are stacked on the substrate 10 in sequence. The stacking arrangement mentioned here means that the other film layers are arranged in sequence along the thickness direction Z of the substrate 10. Among them, the substrate 10 may include multiple film layer structures, and the specific film layer structure composition of the substrate 10 is not limited in the embodiment of the present application. And the thickness direction Z of other film layers located on one side of the substrate 10 is usually consistent with the thickness direction Z of the substrate 10 itself. Therefore, for the convenience of expression, the thickness direction Z of the substrate 10 or the thickness direction Z of other film layers mentioned later in the embodiment of the present application are all illustrated in the same direction.

[0063] The light-emitting functional layer 30 and the isolation structure 20 are located on the same side of the substrate 10. The light-emitting functional layer 30 includes a plurality of light-emitting structures 31, which are the main devices for realizing light-emitting display. Among them, the light-emitting structure 31 includes but is not limited to a red light-emitting structure 31 for emitting red light, a green light-emitting structure 31 for emitting green light, and a blue light-emitting structure 31 for emitting blue light. Each light-emitting structure 31 may include a stacked hole injection layer (Hole Inject Layer, HIL), a hole transport layer (Hole Transport Layer, HTL), a light-emitting layer, an electron injection layer (Electron Inject Layer, EIL) and an electron transport layer (Electron Transport Layer, ETL).

[0064] Optionally, the display panel further includes a first electrode layer 40 and a second electrode layer 50 located on both sides of the light-emitting functional layer 30 in the thickness direction Z, the first electrode layer 40 is located on the side of the light-emitting functional layer 30 away from the substrate 10, the second electrode layer 50 is located on the side of the light-emitting functional layer 30 facing the substrate 10, the first electrode layer 40 is provided with a first electrode 41, the second electrode layer 50 is provided with a second electrode 51, the number of the second electrodes 51 is multiple, the multiple second electrodes 51 are arranged corresponding to the light-emitting structure 31, and the first electrode 41 and the second electrode 51 jointly drive and control whether the light-emitting structure 31 emits light. Exemplarily, the first electrode 41 is a cathode, and the second electrode 51 is an anode.

[0065] The isolation structure 20 can enclose a plurality of opening structures 22, and a plurality of light-emitting structures 31 are disposed in the plurality of opening structures 22, that is, the orthographic projection of the light-emitting structure 31 on the substrate 10 is arranged corresponding to the orthographic projection of the opening structure 22 on the substrate 10, and the orthographic projection of the light-emitting structure 31 on the substrate 10 is at least partially located within the orthographic projection of the opening structure 22 on the substrate 10. When a plurality of opening structures 22 are disposed in a single isolation unit 21, the plurality of light-emitting structures 31 may be disposed in the plurality of opening structures 22 in the same isolation unit 21, or the plurality of light-emitting structures 31 may be disposed in the opening structures 22 in different isolation units 21, and the embodiment of the present application does not limit this.

[0066] Furthermore, the isolation structure 20 can also enclose a light-transmitting opening 23. Unlike the opening structure 22, there is no light-emitting structure 31 at the position corresponding to the light-transmitting opening 23, that is, the orthographic projection of the light-emitting structure 31 on the substrate 10 can be staggered with the orthographic projection of the light-transmitting opening 23 on the substrate 10. There is no corresponding material for forming the isolation structure 20 at the position of the light-transmitting opening 23, so at the position corresponding to the light-transmitting opening 23, the isolation structure 20 will not have an adverse effect on the transmittance of the display panel, thereby ensuring that the display panel can have a higher transmittance at the position corresponding to the light-transmitting opening 23.

[0067] It should be noted that the specific distribution positions of the light-transmitting openings 23 on the display panel are not limited in the embodiments of the present application. For example, the light-transmitting openings 23 may be distributed at various positions of the display panel to meet the needs of a transparent display panel; or the light-transmitting openings 23 may be distributed only at corresponding positions of the display panel for arranging photosensitive elements such as under-screen cameras to improve the photosensitive accuracy of the display panel.

[0068] In addition, the embodiment of the present application does not limit the specific shape and size of the light-transmitting opening 23 and the isolation structure 20, as well as the specific positional relationship between the two. For example, the isolation structure 20 can be a mesh structure, and the light-transmitting opening 23 can be set at the straight line segment position of the mesh structure, or can also be set at the corner position of the mesh structure.

[0069] In some embodiments, Figure 1 As shown, the isolation structure 20 includes a plurality of isolation segments 26 whose extension directions intersect each other, and a connecting portion 27 for connecting adjacent isolation segments 26 , and the light-transmitting opening 23 is arranged through the connecting portion 27 along the thickness direction of the substrate 10 .

[0070] The isolation structure 20 includes a plurality of isolation segments 26, and at least some of the different isolation segments 26 have different extension directions, wherein each isolation segment 26 may be a straight segment structure, or each isolation segment 26 may be a curved segment 61 structure, or some isolation segments 26 may be a straight segment structure, and some isolation segments 26 may be a curved segment 61 structure. When the isolation segment 26 is a curved or other non-linear structure, the extension direction of the isolation segment 26 is the direction of the line connecting its head end and tail end.

[0071] The connecting portion 27 is used to connect adjacent isolation segments 26, and the adjacent isolation segments 26 can be used to enclose and form the same opening structure 22. The connecting portion 27 can be made of the same material as the isolation segments 26 and formed together in the same preparation process. The specific size and shape of the connecting portion 27 are not limited in the embodiments of the present application, as long as the connecting portion 27 can connect the adjacent isolation segments 26 together.

[0072] Furthermore, in the embodiment of the present application, by setting the light-transmitting opening 23 at the position of the connecting portion 27, it helps to increase the distance between the center of the light-transmitting opening 23 and the center of the adjacent opening structure 22, thereby reducing the influence of the light-transmitting opening 23 on the opening structure 22. Of course, in other embodiments, the light-transmitting opening 23 can also be set at the isolation section 26, and the embodiment of the present application is not limited to this.

[0073] In some embodiments, the orthographic projection outer contour of the light-transmitting opening 23 on the substrate 10 is the same as the orthographic projection outer contour of the connecting portion 27 on the substrate 10 .

[0074] In the embodiment of the present application, the outer contour of the orthographic projection of the light-transmitting opening 23 on the substrate 10 is set to be the same as the shape of the outer contour of the orthographic projection of the connecting portion 27 on the substrate 10, so that the outer contour of the light-transmitting opening 23 can be adapted to the outer contour of the connecting portion 27, which helps to adjust the size of the light-transmitting opening 23 and is beneficial to improving the transmittance of the display panel.

[0075] The embodiment of the present application does not specifically limit the orthographic projection shape of the light-transmitting opening 23 on the substrate 10 and the orthographic projection shape of the connecting portion 27 on the substrate 10. Optionally, the orthographic projection of the light-transmitting opening 23 on the substrate 10 may be a circular structure. Further optionally, the orthographic projection of the connecting portion 27 on the substrate 10 may be a circular ring structure.

[0076] The above-mentioned embodiment scheme is applicable to transparent display products and products with fingerprint recognition function, especially to transparent display products with high PPI (Pixels Per Inch, also called pixel density unit) and products with fingerprint recognition function.

[0077] In some embodiments, Figure 2 and Figure 3 As shown, the isolation structure 20 includes a plurality of isolation units 21 , and the isolation units 21 are enclosed to form an opening structure 22 , and at least some of the connected isolation units 21 are spaced apart to form a light-transmitting opening 23 .

[0078] The isolation structure 20 includes a plurality of isolation units 21 arranged at intervals. The structures of different isolation units 21 may be the same or different. The isolation units 21 are enclosed to form an opening structure 22, wherein one isolation unit 21 may be provided with only one opening structure 22, or one isolation unit 21 may be provided with multiple opening structures 22 at the same time. The embodiments of the present application do not limit this.

[0079] In the embodiment of the present application, the isolation structure 20 is provided to include a plurality of isolation units 21 arranged at intervals, so as to form a light-transmitting opening 23 between adjacent isolation units 21. This helps to further increase the size of the light-transmitting opening 23 in the display panel, thereby improving the overall transmittance of the display panel, and has strong practicality.

[0080] At the same time, the embodiment of the present application can meet the stretching needs of the display panel. Specifically, since the isolation units 21 are arranged at intervals from each other, when the display panel needs to be stretched, the relative distance between different isolation units 21 can be increased under the action of external forces and other factors, and the light-emitting structure 31 is only arranged corresponding to the opening structure 22 of the isolation unit 21, and there is no light-emitting structure 31 between adjacent isolation units 21. Therefore, when the position of the isolation unit 21 changes, the light-emitting structure 31 can move with the isolation unit 21, and the distance between different light-emitting structures 31 located at different isolation units 21 can be increased, thereby realizing the adjustment of the relative position between different light-emitting structures 31 and meeting the stretching needs.

[0081] In some embodiments, the isolation unit 21 is provided with a plurality of opening structures 22. That is, a plurality of light emitting structures 31 may be provided corresponding to the same isolation unit 21. Optionally, at least some of the light emitting structures 31 of different colors are located in the plurality of opening structures 22 of the same isolation unit 21.

[0082] In some embodiments, at least some of the light emitting structures 31 are arranged side by side in the first direction X, at least some of the isolation units 21 are arranged side by side in the first direction X, and at least some of the isolation units 21 are arranged side by side in the first direction X.

[0083] In order to improve the display effect of the display panel, the light-emitting structures 31 are usually arranged according to a specific rule to improve the display uniformity of the display panel. Furthermore, at least some of the light-emitting structures 31 are arranged side by side in the first direction X. Specifically, "at least some of the light-emitting structures 31 are arranged side by side in the first direction X" means that at least some of the light-emitting structures 31 are arranged at intervals from each other, and the center lines of some of the light-emitting structures 31 are parallel to the first direction X. Among them, light-emitting structures 31 of the same color can be arranged side by side in the first direction X, or light-emitting structures 31 of different colors can be arranged side by side in the first direction X, and the embodiments of the present application are not limited to this.

[0084] Combined with the above content, it can be known that the existence of the isolation structure 20 can make the formation of the light-emitting structure 31 not need the help of a fine metal mask during the preparation process of the light-emitting structure 31, but the light-emitting material at some positions is removed by evaporation of the entire surface and then etching. Therefore, the existence of the isolation structure 20 will have a great impact on the preparation of the light-emitting structure 31, and will also have a certain impact on the relative position of the light-emitting structure 31.

[0085] On this basis, the embodiment of the present application sets the isolation structure 20 so that at least part of the isolation units 21 are arranged side by side in the first direction X, so that the arrangement of the isolation units 21 can follow the arrangement of at least part of the light-emitting structure 31, so that the layout of the isolation units 21 is more regular. Then, during the preparation process of the light-emitting structure 31, it is helpful to control at least part of the light-emitting structure 31 to be arranged side by side in the first direction X, so as to improve the display uniformity of the display panel. In addition, multiple isolation units 21 are arranged side by side in the first direction X, which can ensure that multiple isolation units 21 can be spaced to form light-transmitting openings 23 in the first direction X, so as to improve the light-transmitting display effect. And it can also meet the stretching needs of the display panel in the first direction X, so as to achieve the stretching effect.

[0086] In addition, in the embodiment of the present application, since the plurality of isolation units 21 are spaced apart from each other, the isolation unit 21 also has the function of isolating the water and oxygen from invading the light-emitting structure 31 from the side, thereby being able to perform a packaging and protection function for the light-emitting structure 31 together with the packaging layer, thereby improving the packaging effect of the light-emitting structure 31.

[0087] It should be noted that all isolation units 21 may be arranged side by side in the first direction X, or only some isolation units 21 may be arranged side by side in the first direction X, and other isolation units 21 may be arranged side by side in other directions. This embodiment of the present application is not limited to this.

[0088] In some embodiments, the light-emitting functional layer 30 includes a plurality of repeating units D, the repeating unit D includes a plurality of light-emitting structures 31 , and at least some of the light-emitting structures 31 in the same repeating unit D are arranged side by side in the first direction X.

[0089] A plurality of repeating units D are shifted and repeated to form a pixel arrangement structure of the display panel, and the number, type and relative position relationship of the light emitting structures 31 in each repeating unit D are the same. In the same repeating unit D, the light emitting structures 31 of the same color may be arranged side by side in the first direction X, or the light emitting structures 31 of different colors may be arranged side by side in the first direction X.

[0090] The composition and arrangement of the light-emitting structure 31 in the repeating unit D are not limited in the present embodiment. It should be noted that: Figure 2 The multiple light emitting structures 31 in the dotted frame refer to the multiple light emitting structures 31 in the same repeating unit D, but Figure 2 It does not constitute a restriction on the composition and arrangement rule of the light-emitting structure 31 in the repeating unit D. The specific structure of the repeating unit D needs to be determined according to actual use requirements, and the embodiments of the present application do not impose any restriction on this.

[0091] Furthermore, since at least part of the light-emitting structures 31 and at least part of the isolation units 21 in the same repeating unit D are arranged along the first direction X, when designing the isolation structure 20 and the light-emitting structure 31, different light-emitting structures 31 in the same repeating unit D can be arranged in different isolation units 21, and at least part of the adjacent isolation units 21 can be arranged side by side along the first direction X, so as to ensure that at least part of the light-emitting structures 31 in the same repeating unit D are arranged side by side in the first direction X when the light-emitting structure 31 is prepared later.

[0092] Of course, in some other embodiments, the light-emitting functional layer 30 includes a repeating unit D, the repeating unit D includes a plurality of light-emitting structures 31 , and at least part of the repeating units D are arranged side by side in the first direction X.

[0093] In this way, when designing the isolation structure 20 and the light-emitting structure 31, different light-emitting structures 31 in different repeating units D can be arranged in different isolation units 21, and at least part of the adjacent isolation units 21 can be arranged side by side along the first direction X, so that when the light-emitting structure 31 is subsequently prepared, it can be ensured that at least part of the repeated units D formed can be arranged side by side in the first direction X.

[0094] Further optionally, each light-emitting structure 31 in the same repeating unit D is located in a plurality of opening structures 22 in the same isolation unit 21 .

[0095] Since a single isolation unit 21 is a continuous structure and is difficult to deform, during the stretching process of the display panel, the multiple light-emitting structures 31 located in the same isolation unit 21 can maintain a fixed relative position. On this basis, in the embodiment of the present application, each light-emitting structure 31 in the same repeating unit D is located in a plurality of opening structures 22 in the same isolation unit 21, so as to ensure that the relative position relationship between each light-emitting structure 31 in the repeating unit D can be kept fixed during the stretching process of the display panel, so that the light-emitting effect of each repeating unit D can remain unchanged, reduce the risk of color deviation of a single repeating unit D, and improve the light-emitting reliability of the repeating unit D.

[0096] In some embodiments, see Figure 4 , some of the isolation units 21 are arranged side by side in the second direction Y, and the first direction X intersects the second direction Y. Exemplarily, the first direction X is perpendicular to the second direction Y.

[0097] In the embodiment of the present application, different isolation units 21 can be arranged side by side along the first direction X and the second direction Y. In this way, the display panel has light-transmitting openings 23 at different positions in the first direction X and the second direction Y, which helps to improve the overall transmittance of the display panel and further meet the light-transmitting display or light-sensing requirements of the display panel. In addition, this design can meet the stretching deformation of the display panel at least in the first direction X and the second direction Y, so as to further increase the size of the display panel and have stronger stretching applicability.

[0098] It should be noted that, in addition to the first direction X and the second direction Y, some isolation units 21 may also be arranged side by side along other directions, depending on factors such as the stretching requirements of the display panel and the arrangement requirements of the light-emitting structure 31 in the light-emitting functional layer 30, and the embodiments of the present application are not limited to this.

[0099] In some embodiments, the light-emitting functional layer 30 includes a plurality of repeating units D, the repeating unit D includes a plurality of light-emitting structures 31 , and at least some of the light-emitting structures 31 in the same repeating unit D are arranged side by side in the second direction Y.

[0100] Since at least part of the light-emitting structures 31 and part of the isolation units 21 in the same repeating unit D are arranged along the second direction Y, when designing the isolation structure 20 and the light-emitting structure 31, different light-emitting structures 31 in the same repeating unit D can be arranged in different isolation units 21, and at least part of the adjacent isolation units 21 can be arranged side by side along the second direction Y, so as to ensure that at least part of the light-emitting structures 31 in the same repeating unit D are arranged side by side in the second direction Y when the light-emitting structure 31 is prepared later.

[0101] In some embodiments, the light-emitting functional layer 30 includes a plurality of repeating units D, the repeating units D include a plurality of light-emitting structures 31 , and at least some of the repeating units D are arranged side by side in the second direction Y.

[0102] In this way, when designing the isolation structure 20 and the light-emitting structure 31, different light-emitting structures 31 in different repeating units D can be arranged in different isolation units 21, and at least part of the adjacent isolation units 21 can be arranged side by side along the second direction Y, so that when the light-emitting structure 31 is subsequently prepared, it can be ensured that at least part of the repeated units D formed can be arranged side by side in the second direction Y.

[0103] In some embodiments, see Figure 5 , any different light emitting structures 31 are arranged in different isolation units 21, that is, each isolation unit 21 is provided with only one opening structure 22. Exemplarily, the orthographic projection of the isolation unit 21 on the substrate 10 is a ring-shaped structure.

[0104] This design allows a light-transmitting opening 23 to exist between any adjacent light-emitting structures 31, thereby further increasing the size ratio of the light-transmitting opening 23 in the display panel, thereby further improving the light-transmitting display effect, or further improving the photosensitivity of the display panel. In addition, during the stretching process of the display panel, the relative distance between any light-emitting structures 31 can be increased, thereby helping to further increase the overall size of the display panel after stretching, increase the deformation of the display panel, and have greater flexibility.

[0105] In some embodiments, Figures 2 to 5 As shown, the display panel further includes a first signal line 60 disposed on one side of the substrate 10 . The first signal line 60 includes a curve segment 61 . The orthographic projection of the curve segment 61 on the substrate 10 at least partially overlaps with the orthographic projection of the light-transmitting opening 23 on the substrate 10 .

[0106] The first signal line 60 and the isolation structure 20 are located on the same side of the substrate 10. The first signal line 60 can be located on the side of the isolation structure 20 facing the substrate 10, or the first signal line 60 can also be arranged on the same layer as part of the structure in the isolation structure 20, and the embodiment of the present application does not limit this. And the embodiment of the present application does not limit the type and overall extension direction of the first signal line 60. Optionally, the first signal line 60 can be a data line for transmitting a data signal; or the first signal line 60 can be a power line for transmitting a power signal to the first electrode 41 or the second electrode 51.

[0107] As can be seen from the foregoing, since the isolation units 21 are spaced apart from each other, when the display panel is stretched, the distance between adjacent isolation units 21 gradually increases, and the size of the entire display panel gradually increases. On this basis, the embodiment of the present application provides a curved segment 61 in the first signal line 60. Compared with a straight line structure, the curved segment 61 can have a larger elongation under the action of external force and other factors, thereby meeting the stretching requirements of the display panel.

[0108] Furthermore, the orthographic projection of the curved segment 61 on the substrate 10 at least partially overlaps with the orthographic projection of the light-transmitting opening 23 on the substrate 10, that is, the orthographic projection of the curved segment 61 on the substrate 10 is located between the orthographic projections of adjacent isolation units 21 on the substrate 10. This design allows the curved segment 61 to deform and gradually straighten as the distance between adjacent isolation units 21 gradually increases, thereby meeting the stretching requirements of the display panel, thereby reducing the risk of the first signal line 60 being broken due to the stretching of the display panel and improving the reliability of signal transmission inside the display panel.

[0109] The embodiment of the present application does not limit the specific shape and size of the curved segment 61. For example, the orthographic projection of the curved segment 61 on the substrate 10 may be in an "S" shape.

[0110] In some embodiments, the isolation structure 20 includes a first isolation portion 24 and a second isolation portion 25 stacked in sequence in a direction away from the substrate 10 . The first isolation portion 24 includes a conductive structure, and the first signal line 60 is electrically connected to the first isolation portion 24 .

[0111] The isolation structure 20 includes at least a first isolation portion 24 and a second isolation portion 25, wherein the second isolation portion 25 is located on a side of the first isolation portion 24 away from the substrate 10. The embodiment of the present application does not limit the size of the first isolation portion 24 and the second isolation portion 25. Exemplarily, the orthographic projection of the first isolation portion 24 on the substrate 10 is located within the orthographic projection of the second isolation portion 25 on the substrate 10.

[0112] The first isolation portion 24 includes a conductive structure, that is, the first isolation portion 24 can be used to realize signal transmission. On this basis, the embodiment of the present application electrically connects the first signal line 60 with the first isolation portion 24, so that a specific signal in the first signal line 60 can be transmitted with the help of the first isolation portion 24. The embodiment of the present application does not limit the connection method between the first isolation portion 24 and the first signal line 60. Exemplarily, the first signal line 60 is located on the side of the first isolation portion 24 facing the substrate 10, and the first signal line 60 and the first isolation portion 24 are electrically connected to each other through a via.

[0113] In some embodiments, see Figure 6 The first signal line 60 and the first isolation portion 24 are arranged on the same layer.

[0114] As can be seen from the foregoing, adjacent isolation units 21 are spaced apart from each other, and no partial film layers such as the light emitting structure 31 are disposed between adjacent isolation units 21. On this basis, a partial supporting film layer can be filled between adjacent isolation units 21, and then the first signal line 60 is disposed on the supporting film layer, so that the first signal line 60 can be disposed on the same layer as the first isolation portion 24 and electrically connected, thereby reducing the occupation of the space of the array layer 90 below by the first signal line 60, and meeting the wiring requirements of the display panel.

[0115] In some embodiments, Figure 6 As shown, the first signal line 60 includes a plurality of conductive segments 62 disposed at intervals, and the conductive segments 62 are electrically connected to the first isolation portion 24 .

[0116] In the embodiment of the present application, the first signal line 60 can be arranged in the same layer as the first isolation portion 24 and be electrically connected, so the first signal line 60 can achieve signal transmission with the help of the first isolation portion 24. On this basis, the first signal line 60 can include a plurality of conductive segments 62 arranged at intervals, and adjacent conductive segments 62 can achieve signal transmission between each other with the help of the first isolation portion 24. Further, the conductive segment 62 can include a curved segment 61 to meet the stretching requirements of the display panel.

[0117] In some embodiments, Figure 2 and Figure 6 As shown, the display panel further includes a first electrode layer 40 disposed on a side of the light-emitting functional layer 30 away from the substrate 10 , and the first electrode layer 40 includes a plurality of first electrodes 41 disposed in a plurality of opening structures 22 .

[0118] Due to the existence of the isolation structure 20, the first electrode layer 40 can include a plurality of first electrodes 41 disposed at intervals, and each first electrode 41 is disposed corresponding to each light emitting structure 31. The first electrode 41 is correspondingly located in the opening structure 22 of the isolation unit 21, and there is no first electrode 41 between adjacent isolation units 21.

[0119] In the embodiment of the present application, the first electrode layer 40 can be transformed from a whole surface structure into a structure including a plurality of first electrodes 41 arranged at intervals through the isolation structure 20, so that during the stretching process of the display panel, different first electrodes 41 can be displaced together with the light-emitting structure 31 and the isolation unit 21, so as to achieve the stretching effect of the display panel, which has strong practicality.

[0120] In some embodiments, the isolation structure 20 includes a first isolation portion 24 and a second isolation portion 25 that are stacked, the first isolation portion 24 includes a conductive structure, and the first electrode 41 is electrically connected to the first isolation portion 24 .

[0121] The first electrode 41 may be arranged in contact with the first isolation portion 24, so that the power signal can be transmitted to the first electrode 41 by means of the first isolation portion 24, so that the first electrode 41 can play a role in driving and controlling the light-emitting structure 31. Further optionally, the first signal line 60 is a power signal line, and the first signal line 60 is electrically connected to the first isolation portion 24, and the first signal line 60 transmits the corresponding power signal to the first electrode 41 through the first isolation portion 24.

[0122] In some embodiments, the display panel further includes a first encapsulation layer 71 disposed on a side of the light-emitting functional layer 30 facing away from the substrate 10 , and the first encapsulation layer 71 includes first encapsulation portions 711 disposed in a plurality of opening structures 22 .

[0123] The first encapsulation layer 71 is used to encapsulate and protect the light emitting structure 31. The first encapsulation layer 71 includes a plurality of first encapsulation parts 711. The plurality of first encapsulation parts 711 are arranged corresponding to the opening structure 22, that is, the plurality of first encapsulation parts 711 can be arranged corresponding to the plurality of light emitting structures 31. This design enables the plurality of first encapsulation parts 711 in the first encapsulation layer 71 to independently encapsulate the plurality of light emitting structures 31, which helps to improve the encapsulation reliability.

[0124] At the same time, the material in the first encapsulation layer 71 will not exist between adjacent isolation units 21, so the presence of the first encapsulation layer 71 will not have a significant impact on the stretching of the display panel. The first encapsulation portion 711 is arranged corresponding to the light emitting structure 31, so the first encapsulation portion 711 can move together with the light emitting structure 31 and the isolation unit 21 to meet the stretching requirements of the display panel.

[0125] The present embodiment does not limit the material composition of the first encapsulation layer 71. Exemplarily, the first encapsulation layer 71 includes an inorganic material.

[0126] Similarly, in some embodiments, such as Figure 6 As shown, the display panel further includes a second encapsulation layer 72 disposed on a side of the first encapsulation layer 71 away from the substrate 10 , and the second encapsulation layer 72 includes second encapsulation portions 721 disposed in a plurality of opening structures 22 .

[0127] The first encapsulation layer 71 and the second encapsulation layer 72 are both used to achieve an encapsulation effect. The second encapsulation layer 72 has a similar structure to the first encapsulation layer 71. The second encapsulation layer 72 also includes a second encapsulation portion 721 corresponding to a plurality of light-emitting structures 31. Therefore, the second encapsulation portion 721 can be displaced along with the light-emitting structure 31 and the isolation unit 21 to meet the stretching requirements of the display panel. The material composition of the second encapsulation layer 72 is not limited in the embodiment of the present application. Exemplarily, the second encapsulation layer 72 includes an organic material.

[0128] In some embodiments, Figure 7 As shown, the display panel further includes a transparent portion T disposed in at least a portion of the light-transmitting opening 23 .

[0129] The transparent portion T refers to a structure formed by a material with a relatively high transmittance, wherein the transparent portion T is disposed in at least a portion of the light-transmitting opening 23, and the presence of the transparent portion T does not have too much influence on the transmittance at the light-transmitting opening 23, which helps to achieve a transparent display effect. In addition, the transparent portion T can also play a certain supporting role for the upper portion of the film layer, so as to reduce the difficulty of manufacturing the display panel and improve the manufacturing yield.

[0130] It should be noted that the material composition of the transparent portion T is limited by the manufacturing of the embodiment of the present application. Optionally, the transparent portion T may also include an elastic material, and the presence of the elastic material may meet the stretching requirements of the display panel. Optionally, the transparent portion T may include an organic material.

[0131] In some embodiments, Figure 7 As shown, the display panel also includes a third encapsulation layer 73 arranged on the side of the light-emitting functional layer 30 away from the substrate 10, and the third encapsulation layer 73 includes a third encapsulation part 731 arranged in a plurality of opening structures 22; the surface of the transparent part T away from the substrate 10 is flush with the surface of the third encapsulation part 731 away from the substrate 10.

[0132] The first encapsulation layer 71, the second encapsulation layer 72 and the third encapsulation layer 73 can together constitute a thin film encapsulation structure, and by providing multiple encapsulation film layers, the encapsulation protection effect on the light emitting structure 31 can be improved. Among them, the first encapsulation layer 71 includes multiple first encapsulation parts 711 provided corresponding to the light emitting structure 31, the second encapsulation layer 72 includes multiple second encapsulation parts 721 provided corresponding to the light emitting structure 31, and the third encapsulation layer 73 includes multiple third encapsulation parts 731 provided corresponding to the light emitting structure 31.

[0133] This design enables the first encapsulation part 711, the second encapsulation part 721 and the third encapsulation part 731 to move together with the light-emitting structure 31, so that the first encapsulation layer 71, the second encapsulation layer 72 and the third encapsulation layer 73 will not have too much influence on the stretching of the display panel, which helps to achieve the stretching needs of the display panel.

[0134] Furthermore, the embodiment of the present application also sets the surface of the third encapsulation layer 73 facing away from the substrate 10 to be flush with the surface of the transparent portion T facing away from the substrate 10, so that the third encapsulation layer 73 and the side of the transparent portion T facing away from the substrate 10 can jointly form a flat surface to facilitate the preparation of subsequent film layers, thereby reducing the difficulty of preparing the display panel.

[0135] In some embodiments, the display panel also includes a pixel definition layer 80 disposed on the side of the isolation structure 20 facing the substrate 10, the pixel definition layer 80 includes a pixel defining portion 81, and a first opening 82 and a second opening 83 enclosed by the pixel defining portion 81 and spaced apart from each other, the light-emitting structure 31 is disposed in a plurality of first openings 82, and the second opening 83 at least partially overlaps the orthographic projection of the light-transmitting opening 23 on the substrate 10.

[0136] The pixel definition layer 80 is located on the side of the isolation structure 20 facing the substrate 10. Specifically, the isolation structure 20 is located on the side of the pixel defining portion 81 away from the substrate 10. The pixel definition layer 80 is provided with a plurality of first openings 82, the second electrode 51 can be exposed to the first openings 82, and the light emitting structure 31 can be located in the first openings 82. The first openings 82 in the pixel definition layer 80 can be arranged corresponding to the opening structure 22 in the isolation structure 20, that is, the orthographic projection of the first opening 82 on the substrate 10 is located within the orthographic projection of the opening structure 22 on the substrate 10.

[0137] In addition to the first opening 82, the pixel definition layer 80 is further provided with a second opening 83, which is spaced apart from the first opening 82, and the second opening 83 is arranged so as to overlap the orthographic projection of the substrate 10 and the orthographic projection of the light-transmitting opening 23 on the substrate 10. Optionally, the orthographic projection of the light-transmitting opening 23 on the substrate 10 is located within the orthographic projection of the second opening 83 on the substrate 10. This design can further improve the transmittance of the display panel at the light-transmitting opening 23, thereby improving the transparent display effect. Further optionally, at least a partial structure of the transparent portion T can also be provided in the second opening 83.

[0138] In some embodiments, see Figure 8 The isolation structure 20 includes a first isolation portion 24 and a second isolation portion 25 located on a side of the first isolation portion 24 away from the substrate 10 . The first isolation portion 24 is at least partially located in the second opening 83 and covers at least a portion of the side wall of the pixel defining portion 81 .

[0139] The first isolation portion 24 can include a covering portion 241 , which is located on a side of the pixel defining portion 81 facing the second opening 83 in a direction parallel to the plane of the substrate 10 and can cover at least a portion of a sidewall of the pixel defining portion 81 .

[0140] In the embodiment of the present application, at least a portion of the first isolation portion 24 can extend into the second opening 83 and can cover at least a portion of the side wall of the pixel defining portion 81. This design enables the first isolation portion 24 to protect the side wall of the pixel defining portion 81 facing the second opening 83, thereby enhancing the structural reliability of the display panel.

[0141] In some embodiments, see Fig. 9 The display panel further includes an array layer 90 disposed on a side of the pixel definition layer 80 facing the substrate 10 . The array layer 90 is provided with a third opening 91 . The third opening 91 is connected to the second opening 83 .

[0142] The array layer 90 generally includes a plurality of stacked conductive layers and an insulating layer between adjacent conductive layers. A circuit structure is provided in the array layer 90 to meet the use requirements of the display panel. For example, the first signal line 60 may be located in the array layer 90 .

[0143] On this basis, the embodiment of the present application sets a third opening 9191 in the array layer 90. The third opening 919 can be set completely through the array layer 90 along the thickness direction Z, or can only penetrate part of the structure in the array layer 90. The embodiment of the present application is not limited to this. The third opening 91 is connected to the second opening 83. This design can further improve the transmittance of the display panel at the light-transmitting opening 23, thereby improving the transparent display effect. Further optionally, at least a part of the structure of the transparent portion T can be set in the third opening 91.
