[0065] 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.

[0066] 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.

[0067] As users' demand for larger display sizes increases, the problem of narrowing the display panel border size has become particularly prominent. In related technologies, multiple circuit structures are usually required to be arranged at the display panel border position to meet the normal operation needs of the display panel. However, the existence of these circuit structures makes it difficult to reduce the border size of the display panel. Forcibly reducing the border size will cause the display panel to display abnormally or reduce the display quality.

[0068] In view of this, first of all, please refer to Figure 1 and Figure 2 The embodiment of the present application provides a display panel, the display panel has a first area A1 and a second area A2 arranged around the first area A1, the display panel includes a substrate 10, an isolation structure 20, a light-emitting functional layer 30, a light-emitting control circuit D1 and a blocking portion 40, the isolation structure 20 is arranged on one side of the substrate 10, and the isolation structure 20 encloses a plurality of opening structures 21 arranged at intervals, the light-emitting functional layer 30 is arranged on one side of the substrate 10 and located in the first area A1, the light-emitting functional layer 30 includes a plurality of light-emitting structures 31 arranged in the plurality of opening structures 21, and there is at least one light-emitting structure 31 in one opening structure 21. For example, there is one light-emitting structure 31 in one opening structure 21, or there are multiple light-emitting structures 31 with the same light-emitting color in one opening structure 21.

[0069] The light-emitting control circuit D1 is located in the second area A2, the blocking portion 40 is disposed in the second area A2, and at least a portion of the blocking portion 40 is located on the side of the light-emitting control circuit D1 away from the substrate 10 to block part of the film structure from flowing to the side of the blocking portion 40 away from the first area A1.

[0070] The display panel has at least two areas, a first area A1 and a second area A2. The first area A1 is a display area in the display panel for achieving a display effect. The second area A2 is arranged on the outer peripheral side of the first area A1, and is mainly used to arrange the light-emitting control circuit and the gate drive circuit in the display panel. The second area A2 is a non-display area, and the second area A2 includes a frame area. The embodiment of the present application does not limit the size and shape of the first area A1 and the second area A2. For example, the first area A1 can be a square structure, and the second area A2 can be a square ring structure. Or the first area A1 can be a circular structure, and the second area A2 can be a circular ring structure.

[0071] 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.

[0072] 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 is located in the first area A1 and includes a plurality of light-emitting structures 31. The light-emitting structure 31 is the main device 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).

[0073] Further optionally, the display panel may further include a first electrode 51 and a second electrode 52 located on both sides of the light emitting structure 31 along the thickness direction Z, the first electrode 51 is located on the side of the light emitting structure 31 away from the substrate 10, and the second electrode 52 is located on the side of the light emitting structure 31 facing the substrate 10. There are multiple second electrodes 52, and the multiple second electrodes 52 are arranged corresponding to the light emitting structure 31. The first electrode 51 and the second electrode 52 jointly drive and control whether the light emitting structure 31 emits light. Exemplarily, the first electrode 51 is a cathode and the second electrode 52 is an anode.

[0074] The isolation structure 20 can enclose a plurality of opening structures 21. For example, the orthographic projection of the isolation structure 20 on the substrate 10 can be a mesh structure. The plurality of light-emitting structures 31 are arranged in the plurality of opening structures 21, 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 21 on the substrate 10, and the orthographic projection of the light-emitting structure 31 on the substrate 10 is at least partially located in the orthographic projection of the opening structure 21 on the substrate 10. Furthermore, in the preparation process of the light-emitting functional layer 30, due to the existence of the isolation structure 20, the fine metal mask can be eliminated.

[0075] Specifically, taking the preparation of the red light-emitting structure 31 before the preparation of the green light-emitting structure 31 as an example, since the fine metal mask is eliminated, the red light-emitting material corresponding to the red light-emitting structure 31 will first fall into each opening structure 21, and then the red light-emitting material in a part of the opening structure 21 will be selectively etched away, and the red light-emitting material in a part of the opening structure 21 will be retained to form the red light-emitting structure 31. After that, the green light-emitting material corresponding to the green light-emitting structure 31 will fall into each opening structure 21, and then the green light-emitting material in a part of the opening structure 21 will be selectively etched away, and the green light-emitting material in a part of the opening structure 21 will be retained to form the green light-emitting structure 31.

[0076] In addition to the above-mentioned film layers, the display panel also includes a variety of other film layer structures, some of which have a certain fluidity due to factors such as material composition. In order to achieve an effective cutoff effect on such film layer structures, the display panel in the embodiment of the present application is also provided with a blocking portion 40. The blocking portion 40 is located in the second area A2, and mainly serves to block and reduce the probability of some film layers flowing to the side of the blocking portion 40 away from the first area A1, thereby improving the reliability of the internal structure of the display panel.

[0077] Generally, the film structure with fluidity itself has a certain thickness, and the closer to the edge of the display panel, the thickness of the film structure will gradually decrease. On this basis, if the blocking portion 40 is set at a position closer to the first area A1, the size of the blocking portion 40 in the thickness direction Z needs to be set larger to meet the blocking needs, but this is not conducive to the overall thickness design of the display panel. In view of this, the blocking portion 40 is usually located at a position far from the first area A1. Further, in the related art, the blocking portion 40 will be located on the side of the light emitting control circuit D1 away from the first area A1.

[0078] The light emitting control circuit D1 is located in the second area A2 , and the blocking portion 40 is located on a side of the light emitting control circuit D1 away from the first area A1 , that is, the blocking portion 40 and the light emitting control circuit D1 are spaced apart in a direction parallel to the plane of the substrate 10 .

[0079] In the embodiment of the present application, since the isolation structure 20 encloses and forms a plurality of opening structures 21, and at least part of the opening structures 21 can be used to accommodate a film structure with fluidity, the existence of the isolation structure 20 can reduce the thickness of part of the film in the second area A2. On this basis, the embodiment of the present application can move the blocking part 40 appropriately toward the direction close to the first area A1 without increasing the height of the blocking part 40, so that at least part of it is located on the side of the light-emitting control circuit D1 away from the substrate 10, which helps to improve the problem of the excessive size of the display panel frame due to the excessive distance between the blocking part 40 and the first area A1, that is, it helps to reduce the frame size of the display panel and improve the display effect.

[0080] It should be noted that the blocking portion 40 may be completely located on the side of the light emitting control circuit D1 away from the substrate 10; or the blocking portion 40 may be partially located on the side of the light emitting control circuit D1 away from the substrate 10, and partially located on the side of the light emitting control circuit D1 close to the first area A1; or the blocking portion 40 may be partially located on the side of the light emitting control circuit D1 away from the substrate 10, and partially located on the side of the light emitting control circuit D1 away from the first area A1, and the embodiment of the present application does not limit this. Among them, since the light emitting control circuit D1 itself has a certain thickness dimension, the presence of the light emitting control circuit D1 helps to reduce the height dimension of at least part of the structure of the blocking portion 40 located on the side of the light emitting control circuit D1 away from the substrate 10, thereby reducing the material cost corresponding to the blocking portion 40, which has strong practicality.

[0081] In some embodiments, Figure 1 and Figure 2 As shown, the display panel further includes a first encapsulation layer 71 disposed on the side of the light-emitting functional layer 30 facing away from the substrate 10 . The first encapsulation layer 71 includes an organic material and is partially located in the opening structure 21 .

[0082] The first encapsulation layer 71 is located on the side of the light-emitting functional layer 30 away from the substrate 10, that is, on the side of the light-emitting surface of the light-emitting structure 31. The first encapsulation layer 71 is partially located in the first area A1 and partially located in the second area A2. The first encapsulation layer 71 is mainly used to encapsulate and protect the light-emitting structure 31, reduce the risk of water and oxygen intruding into the light-emitting structure 31, and improve the light-emitting reliability of the display panel.

[0083] The first encapsulation layer 71 includes organic materials and has a certain fluidity. However, since the first encapsulation layer 71 can be partially located in the opening structure 21, the opening structure 21 can play a certain overflow accommodating role for the first encapsulation layer 71, thereby reducing the thickness of the first encapsulation layer 71 in the second area A2, and then reducing the distance between the blocking portion 40 and the first area A1, so that it is at least partially located on the side of the light-emitting control circuit D1 away from the substrate 10, which helps to achieve a narrow-frame display effect of the display panel.

[0084] In some embodiments, the display panel further includes a second encapsulation layer 72 disposed between the first encapsulation layer 71 and the light-emitting functional layer 30 , and a third encapsulation layer 73 located on the side of the first encapsulation layer 71 away from the substrate 10 , and the second encapsulation layer 72 and the third encapsulation layer 73 include inorganic materials.

[0085] The second encapsulation layer 72 and the third encapsulation layer 73 are respectively located on both sides of the first encapsulation layer 71 in the thickness direction Z. The first encapsulation layer 71, the second encapsulation layer 72 and the third encapsulation layer 73 together form a thin film encapsulation structure, thereby improving the encapsulation protection effect of the light-emitting functional layer 30. Among them, the second encapsulation layer 72 and the third encapsulation layer 73 both include inorganic materials, and the second encapsulation layer 72 and the third encapsulation layer 73 can play a certain role in limiting and blocking the first encapsulation layer 71.

[0086] Further optionally, the second encapsulation layer 72 includes a plurality of second encapsulation portions 721 disposed in the opening structure 21 , and the second encapsulation portions 721 and the blocking portions 40 are spaced apart from each other in a direction parallel to the substrate 10 .

[0087] Due to the existence of the isolation structure 20 , the packaging material used to form the second packaging layer 72 will also fall into the opening structure 21 , thereby forming a plurality of second packaging parts 721 arranged corresponding to the opening structure 21 , wherein different second packaging parts 721 are arranged at intervals from each other.

[0088] In the embodiment of the present application, due to the existence of the blocking portion 40, the blocking portion 40 can block overflow of the first encapsulation layer 71, thereby reducing the risk of the first encapsulation layer 71 extending to the side of the blocking portion 40 away from the first area A1, thereby improving the packaging reliability of the display panel.

[0089] In some embodiments, the third encapsulation layer 73 is partially located on a side of the barrier 40 facing away from the substrate 10 , that is, the third encapsulation layer 73 may extend from the first area A1 to the second area A2 and cover at least a portion of the barrier 40 .

[0090] Under this design, the blocking portion 40 can cooperate with the third encapsulation layer 73 to jointly limit and block the first encapsulation layer 71, further reducing the risk of the first encapsulation layer 71 extending to the side of the blocking portion 40 away from the first area A1, thereby improving the packaging reliability of the display panel.

[0091] In some embodiments, Figure 2 As shown, the display panel further includes a gate driving circuit D2 located between the light emitting control circuit D1 and the first area A1 , and the blocking portion 40 is located on a side of the gate driving circuit D2 away from the first area A1 .

[0092] The gate driving circuit D2 may include a multi-stage shift register cascaded with each other, and the multi-stage shift register may sequentially output a conduction level to sequentially scan each row of pixel circuits located in the first area A1 to meet display requirements.

[0093] The gate driving circuit D2 and the light emitting control circuit D1 are both located in the second area A2, and the gate driving circuit D2 is located on the side of the light emitting control circuit D1 close to the first area A1. The distance between the gate driving circuit D2 and the first area A1 is relatively close. On this basis, in order to ensure the blocking overflow effect of the blocking portion 40 on the first encapsulation layer 71, the embodiment of the present application also sets the blocking portion 40 on the side of the gate driving circuit D2 away from the first area A1, that is, the distance between the blocking portion 40 and the first area A1 is greater than the distance between the gate driving circuit D2 and the first area A1. In this way, it can be ensured that there can be a certain distance dimension between the blocking portion 40 and the first area A1, thereby improving the blocking overflow effect of the blocking portion 40 on the first encapsulation layer 71 without increasing the height dimension of the blocking portion 40.

[0094] In some embodiments, the display panel further includes a first insulating portion 90 disposed between the light emitting control circuit D1 and at least a portion of the blocking portion 40 .

[0095] The first insulating part 90 can cover at least part of the structure of the light emitting control circuit D1. For example, the orthographic projection of the first insulating part 90 on the substrate covers the orthographic projection of the light emitting control circuit D1 on the substrate. Therefore, after the light emitting control circuit D1 is prepared, the first insulating part 90 can isolate the light emitting control circuit D1 from the air. In addition, during the subsequent preparation process of the metal layer, the first insulating part 90 can also protect the light emitting control circuit D1, reduce the risk of over-engraving of the light emitting control circuit D1, and improve reliability.

[0096] In addition, the first insulating portion 90 can insulate the blocking portion 40 from the light emitting control circuit D1, thereby improving the operational reliability of the light emitting control circuit D1. As can be seen from the foregoing, the blocking portion 40 can be completely located on the side of the light emitting control circuit D1 away from the substrate 10, or the blocking portion 40 can also be partially located on the side of the light emitting control circuit D1 away from the substrate 10, and partially located on the side of the light emitting control circuit D1 away from the first area A1. In view of this, the first insulating portion 90 can be completely located on the side of the light emitting control circuit D1 away from the substrate 10, or the first insulating portion 90 can be partially located on the side of the light emitting control circuit D1 away from the substrate 10, and partially located on the side of the light emitting control circuit D1 away from the first area A1.

[0097] When the blocking portion 40 is located on the side of the light emitting control circuit D1 away from the substrate 10 , the first insulating portion 90 can increase the distance between the blocking portion 40 and the substrate 10 , thereby reducing the required height dimension of the blocking portion 40 and the corresponding material cost, which has strong practicality.

[0098] In some optional embodiments, the orthographic projection of the blocking portion 40 on the substrate 10 is located within the orthographic projection of the first insulating portion 90 on the substrate 10. In this way, the insulation effect of the first insulating portion 90 on the blocking portion 40 and the light-emitting control circuit D1 can be further improved, thereby improving reliability. In addition, due to the presence of the first insulating portion 90, the distance between the blocking portion 40 and the substrate 10 can be increased, thereby reducing the height of the blocking portion 40 and reducing the material cost corresponding to the blocking portion 40.

[0099] Further optionally, the orthographic projection of the blocking portion 40 on the substrate 10 is located within the orthographic projection of the light emitting control circuit D1 on the substrate 10 .

[0100] In some embodiments, see Figure 3 The first insulating portion 90 extends from the first area A1 to the second area A2, and the orthographic projection of the first insulating portion 90 on the substrate 10 covers the orthographic projection of the light emitting control circuit D1 on the substrate. That is, the partial structure of the first insulating portion 90 located in the first area A1 is connected to the partial structure of the first insulating portion 90 located in the second area A2.

[0101] In the implementation of the present application, by extending the first insulating portion 90 from the first area A1 to the second area A2, the first insulating portion can not only play the role of insulating and isolating different conductive structures in the first area A1, but also play the role of covering and protecting the light-emitting control circuit D1 in the second area, thereby improving the reliability of the display panel. Further optionally, the first insulating portion 90 can be reused as a planarization layer, which can provide a flat surface to reduce the difficulty of subsequent preparation of the display panel and improve the preparation accuracy of the display panel, which has strong practicality.

[0102] In some embodiments, see Figure 4 The blocking portion 40 includes a plurality of blocking columns 41 arranged at intervals, and at least some of the blocking columns 41 are located on a side of the light emitting control circuit D1 away from the substrate 10 .

[0103] As can be seen from the above content, due to the existence of the isolation structure 20, the distance between the blocking portion 40 and the first area A1 can be appropriately reduced, so that the blocking portion 40 is at least partially located on the side of the light emitting control circuit D1 away from the substrate 10. On this basis, under the premise of meeting the requirement of a narrow frame of the display panel, the blocking portion 40 can be provided to include a plurality of blocking columns 41 arranged at intervals, and each blocking column 41 can play a role in blocking overflow of the first encapsulation layer 71, thereby further reducing the wind direction of the first encapsulation layer 71 extending to the side of the blocking portion 40 away from the substrate 10, thereby improving the encapsulation reliability.

[0104] It should be noted that the embodiment of the present application does not limit the positional relationship between each blocking column 41 and the light emitting control circuit D1. For example, at least part of the blocking columns 41 are located on the side of the light emitting control circuit D1 away from the substrate 10, or part of the blocking columns 41 can also be located on the side of the light emitting control circuit D1 away from the first area A1, or part of the blocking columns 41 can also be located on the side of the light emitting control circuit D1 close to the first area A1.

[0105] In some optional embodiments, each blocking column 41 is located on the side of the light-emitting control circuit D1 away from the substrate 10. This helps to increase the distance between the blocking column 41 and the substrate 10 in the thickness direction Z, thereby reducing the overall height of the blocking portion 40, thereby reducing the material cost corresponding to the blocking column 41, and has strong practicality.

[0106] In addition, the embodiment of the present application does not limit the number of the blocking pillars 41. Optionally, the number of the blocking pillars 41 is greater than 2. Exemplarily, the number of the blocking pillars 41 is 3, 4, or 5.

[0107] In some embodiments, please refer to Figure 5 The display panel further includes a first signal line 60 located in the second area A2 and a first electrode 51 located on a side of the light emitting structure 31 away from the substrate 10 . The first signal line 60 is electrically connected to the first electrode 51 through the isolation structure 20 .

[0108] Similar to the light-emitting structure 31 , the preparation of the first electrode 51 may not rely on a fine metal mask plate, that is, the display panel may include a plurality of first electrodes 51 disposed in the opening structure 21 , and the plurality of first electrodes 51 are disposed corresponding to the plurality of light-emitting structures 31 to realize driving control of the light-emitting structure 31 .

[0109] Furthermore, the first electrode 51 is electrically connected to the isolation structure 20, that is, the isolation structure 20 may include a conductive material, and the first electrode 51 and the conductive material in the isolation structure 20 can be interconnected. Under this design, the power signal corresponding to the first electrode 51 can be transmitted to the first electrode 51 by means of the isolation structure 20 to meet the transmission needs of the power signal.

[0110] It should be noted that the conductive material in the isolation structure 20 for electrically connecting with the first electrode 51 can be continuously arranged, that is, the isolation structure 20 can be used to achieve the effect of each first electrode 51 transmitting a power signal of the same voltage. Alternatively, the conductive material in the isolation structure 20 for electrically connecting with the first electrode 51 can also be intermittent or insulated from each other, that is, at least some of the different first electrodes 51 can also receive or transmit power signals of different voltages with the help of the isolation structure 20, so as to achieve independent or partitioned control of the light-emitting structure 31, and the embodiment of the present application is not limited to this.

[0111] The display panel further includes a first signal line 60, which is used to transmit a corresponding power signal to the first electrode 51. In the related art, the first signal line 60 is directly connected to the first electrode 51 to transmit the power signal to the first electrode 51. In the embodiment of the present application, the first signal line 60 is electrically connected to the first electrode 51 through the isolation structure 20, that is, the power signal can be transmitted with the help of the isolation structure 20, which helps to reduce the difficulty of the routing layout of the first signal line 60 and reduce the manufacturing cost of the display panel.

[0112] In some optional embodiments, the first signal line 60 is located along the first direction X on one side of the isolation structure 20 .

[0113] In the related art, the display panel includes only one first electrode 51 of a whole surface, and the first signal line 60 for electrically connecting with the first electrode 51 is usually located in the second area A2 and arranged in a ring structure around the outer periphery of the first electrode 51. This design makes the first electrode 51 occupy too much size at the position of the display panel frame, which is not conducive to achieving a narrow frame effect.

[0114] However, in the embodiment of the present application, the first signal line 60 is not directly connected to the first electrode 51, but the power signal is transmitted to each first electrode 51 by means of the isolation structure 20. Specifically, since the isolation structure 20 itself is set corresponding to each first electrode 51, and signal transmission can be achieved between the two. Therefore, there is no need to extend the first signal line 60 to the position of each first electrode 51, that is, the first signal line 60 does not need to be set around each first electrode 51, and it is only necessary to set the first signal line 60 on one side of the isolation structure 20 along the first direction X, and electrically connect and set it with the isolation structure 20. In this way, the power signal in the first signal line 60 can be transmitted to each first electrode 51 by means of the isolation structure 20, so as to meet the needs of signal transmission. And since the first signal line 60 is only located on one side of the isolation structure 20 along the first direction X, rather than in a ring structure, it helps to reduce the frame size of the display panel and improve the display effect.

[0115] In some embodiments, the orthographic projection of the blocking portion 40 on the substrate 10 and the orthographic projection of the first signal line 60 on the substrate are arranged to be offset.

[0116] Since the first signal line 60 is only located on one side of the isolation structure 20 along the first direction X, rather than being arranged around the circumference of the isolation structure 20, the first signal line 60 is not present at some positions in the second area A2. On this basis, the orthographic projection of the blocking portion 40 on the substrate 10 can be staggered with the orthographic projection of the first signal line 60 on the substrate 10, that is, the first signal line 60 will not affect the layout design of the blocking portion 40, which helps to reduce the risk of physical interference between the two and improve the reliability of the display panel.

[0117] In some embodiments, the display panel further includes a driver chip IC disposed in the second area A2 , the first signal line 60 is electrically connected to the driver chip IC, and the first signal line 60 is located between the driver chip IC and the isolation structure 20 .

[0118] The driver chip IC is a driving control element, and the driver chip IC can realize the control of the first electrode 51. Further, the driver chip IC is located in the second area A2 and is located on one side of the isolation structure 20 along the first direction X. On this basis, in order to realize the electrical connection between the driver chip IC and the first electrode 51, the embodiment of the present application adds a first signal line 60 between the driver chip IC and the isolation structure 20. The first signal line 60 is located between the driver chip IC and the isolation structure 20 along the first direction X. The driver chip IC transmits the corresponding power signal to the first signal line 60, and then transmits it to the isolation structure 20 with the help of the first signal line 60. Finally, the isolation structure 20 transmits the power signal to the first electrode 51 to realize the driving control of the first electrode 51.

[0119] Further, in some embodiments, see Figure 6 The second area A2 includes a first partition A21 and a second partition A22 located between the driving chip IC and the isolation structure 20 , and the first partition A21 and the second partition A22 are arranged side by side in the second direction Y.

[0120] The first signal line 60 in the first partition A21 and the first signal line 60 in the second partition A22 are insulated from each other.

[0121] The first partition A21 and the second partition A22 are both located between the driver chip IC and the isolation structure 20. The specific positional relationship between the first partition A21 and the second partition A22 is not limited in the embodiment of the present application, as long as the first partition A21 and the second partition A22 are arranged side by side in the second direction Y. Optionally, the first direction X and the second direction Y are arranged perpendicularly.

[0122] The first partition A21 and the second partition A22 are both provided with a first signal line 60. The first partition A21 may have only one first signal line 60, or the first partition A21 may have multiple first signal lines 60. Similarly, the second partition A22 may have only one first signal line 60, or the second partition A22 may have multiple first signal lines 60.

[0123] As can be seen from the foregoing, the first signal lines 60 are all electrically connected to the isolation structure 20, so as to achieve electrical connection with the first electrode 51 with the help of the isolation structure 20. On this basis, the first signal line 60 in the first partition A21 and the first signal line 60 in the second partition A22 are insulated from each other, that is, the partial structure of the isolation structure 20 used for electrical connection with the first signal line 60 in the first partition A21 and the partial structure of the isolation structure 20 used for electrical connection with the first signal line 60 in the second partition A22 are insulated from each other, so that the first signal line 60 in the first partition A21 and the first signal line 60 in the second partition A22 can respectively control different first electrodes 51, thereby helping to improve the control accuracy.

[0124] In some embodiments, see Figure 7 The isolation structure 20 includes a first isolation portion 22 and a second isolation portion 23 which are stacked in sequence in a direction away from the substrate 10 , and the orthographic projection of the first isolation portion 22 on the substrate 10 is located within the orthographic projection of the second isolation portion 23 on the substrate 10 .

[0125] The specific size and shape of the first isolation portion 22 and the second isolation portion 23 are not limited in the embodiment of the present application. For example, the longitudinal section of the isolation structure 20 can be T-shaped. This design helps in the preparation process of the light-emitting functional layer 30 and the first electrode 51 layer, making it difficult for the light-emitting material and the electrode material to extend along the side wall of the first isolation portion 22 to the side wall of the second isolation portion 23, thereby realizing the preparation and mutual separation of the light-emitting structure 31 and the first electrode 51 in different opening structures 21 without the need for a fine metal mask.

[0126] The embodiment of the present application does not limit the material composition of the first isolation portion 22 and the second isolation portion 23. The first isolation portion 22 and the second isolation portion 23 may both include conductive materials, or the first isolation portion 22 includes conductive materials, while the second isolation portion 23 includes insulating materials, as long as the first electrode 51 can achieve signal transmission with the aid of the isolation structure 20.

[0127] In addition, the first signal line 60 may be completely located in the second area A2, or the first signal line 60 may also partially extend into the first area A1. Similarly, the isolation structure 20 may be completely located in the first area A1, or the isolation structure 20 may also partially extend into the second area A2, which is not limited in the present embodiment.

[0128] In some embodiments, the first isolation portion 22 includes a conductive material, and the first electrode 51 is electrically connected to the first isolation portion 22 .

[0129] The first signal line 60 can transmit the power signal to the first electrode 51 with the help of the first isolation part 22, wherein the first electrode 51 can be in direct contact with the first isolation part 22, or the first electrode 51 can be electrically connected to the first isolation part 22 with the help of other conductive structures, and the embodiments of the present application are not limited to this.

[0130] In the embodiment of the present application, by providing a conductive material in the first isolation portion 22, the first signal line 60 can transmit the power signal to the first electrode 51 with the help of the first isolation portion 22, thereby meeting the signal transmission requirements. Furthermore, by providing an extension path of the first isolation portion 22 in the first area A1, the first isolation portion 22 can extend to the range of each area in the first area A1, and then the first signal line 60 only needs to be provided on one side of the isolation structure 20 along the first direction X, and the first signal line 60 does not need to be provided around the first area A1, thereby reducing the frame size of the display panel.

[0131] The embodiment of the present application does not limit the positional relationship between the first signal line 60 and the first isolation portion 22. In some embodiments, at least part of the first signal line 60 is in contact with the first isolation portion 22, that is, at least part of the power signal in the first signal line 60 can be directly transmitted to the first isolation portion 22. Further, if the isolation structure 20 also includes other conductive structures electrically connected to the first isolation portion 22, the first signal line 60 can also be in contact with the other conductive structures.

[0132] In some embodiments, see Figure 8 The isolation structure 20 further includes a third isolation portion 24 located on a side of the first isolation portion 22 facing the substrate 10 . The third isolation portion 24 includes a conductive material and is electrically connected to the first isolation portion 22 .

[0133] The isolation structure 20 includes at least a first isolation portion 22, a second isolation portion 23, and a third isolation portion 24. The embodiment of the present application does not limit the size and shape of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24. Exemplarily, the orthographic projection of the first isolation portion 22 on the substrate 10 is located within the orthographic projection of the third isolation portion 24 on the substrate 10, that is, the longitudinal cross-section of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24 is in an I-shape.

[0134] Similar to the first isolation portion 22, the third isolation portion 24 also includes a conductive material, and the first electrode 51 can directly contact the third isolation portion 24 to achieve electrical connection with the first isolation portion 22 by means of the third isolation portion 24. Optionally, the first electrode 51 is overlapped with the third isolation portion 24. Further, the first electrode 51 can be partially located on the side of the third isolation portion 24 away from the substrate 10, and the provision of the third isolation portion 24 helps to improve the reliability of the electrical connection between the first electrode 51 and the isolation structure 20.

[0135] In some embodiments, the second isolation portion 23 includes a conductive material.

[0136] Similar to the first isolation portion 22, the second isolation portion 23 also includes a conductive material, that is, the second isolation portion 23 can also be used to realize the signal transmission function, wherein the first isolation portion 22 and the second isolation portion 23 can be electrically connected to each other, that is, the second isolation portion 23 is also used to transmit the power signal, or the first isolation portion 22 and the second isolation portion 23 can also be insulated, that is, the second isolation portion 23 is not used to transmit the power signal, and the embodiments of the present application do not limit this.

[0137] Further optionally, the first isolation portion 22 is electrically connected to the second isolation portion 23 , and at least a portion of the first signal line 60 is in contact with the second isolation portion 23 .

[0138] In this case, the first isolation portion 22 can be directly in contact with the second isolation portion 23, and the same electrical signal is transmitted in the first isolation portion 22 and the second isolation portion 23. At this time, the first signal line 60 can be in contact with the second isolation portion 23, and the power signal in the first signal line 60 is transmitted to the first isolation portion 22 by means of the second isolation portion 23, and then transmitted to the first electrode 51 by means of the first isolation portion 22, thereby meeting the need for power signal transmission.

[0139] In some embodiments, see Fig. 9 The isolation structure 20 further includes a second insulating portion 25 disposed between the first isolation portion 22 and the second isolation portion 23 .

[0140] The embodiment of the present application does not limit the size of the second insulating portion 25 relative to the first isolating portion 22 and the second isolating portion 23. For example, the orthographic projection of the first isolating portion 22 on the substrate 10 is located within the orthographic projection of the second isolating portion 25 on the substrate 10, and the orthographic projection of the second isolating portion 25 on the substrate 10 is located within the orthographic projection of the second isolating portion 23 on the substrate 10. This helps to further reduce the risk of the light-emitting material and the electrode material extending from the side wall of the first isolating portion 22 to the side wall of the second isolating portion 23, thereby improving the manufacturing reliability of the display panel.

[0141] Due to the existence of the first insulating portion 90, the first isolating portion 22 and the second isolating portion 23 are in an insulated state, and the power signal in the first isolating portion 22 will not be transmitted to the second isolating portion 23. On this basis, the display panel can transmit other different types of signals with the help of the second isolating portion 23, which helps to reduce the number of internal wirings of the display panel and reduce the difficulty of wiring design. Optionally, the second isolating portion 23 can be used for touch signals.

[0142] In some embodiments, an etching selectivity ratio of the first isolation portion 22 to the second isolation portion 23 is greater than 1.

[0143] The etching selectivity refers to the relative etching rate of one material compared to another material under the same etching conditions. Since the etching selectivity of the first isolation portion 22 relative to the second isolation portion 23 is greater than 1, under the same etching conditions, the etching rate corresponding to the first isolation portion 22 is greater than the etching rate of the second isolation portion 23.

[0144] On this basis, the first isolation portion 22 and the second isolation portion 23 can be arranged to be prepared and formed by the same etching process. This can not only reduce the preparation process of the display panel and improve the preparation efficiency, but also ensure that the orthographic projection of the first isolation portion 22 on the substrate 10 after preparation can be located within the orthographic projection of the second isolation portion 23 on the substrate 10, which has strong practicality.

[0145] In some embodiments, Figure 2 As shown, the display panel further includes a pixel definition layer 80, and the isolation structure 20 is disposed on the side of the pixel definition layer 80 away from the substrate 10, or the isolation structure 20 is disposed in an opening of the pixel definition layer 80, and the opening can be a through hole or a blind hole of the pixel definition layer 80. The pixel definition layer 80 includes a pixel defining portion 81 and a pixel opening 82 formed by the pixel defining portion 81, and the light emitting structure 31 is at least partially located in the pixel opening 82.

[0146] The pixel definition layer 80 includes a pixel defining portion 81 and a pixel opening 82. The pixel opening 82 is arranged corresponding to the opening structure 21. For example, the orthographic projection of the pixel opening 82 on the substrate 10 can be located within the orthographic projection of the opening structure 21 on the substrate 10, and the light-emitting structure 31 and part of the structure in the first electrode 51 can be located within the pixel opening 82.

[0147] In some embodiments, the pixel definition layer 80 is partially located on a side of the barrier 40 facing away from the substrate 10 .

[0148] As can be seen from the above content, due to the existence of the isolation structure 20, the first encapsulation layer 71 will be terminated near the junction of the first area A1 and the second area A2, so the first encapsulation layer 71 cannot effectively block the second encapsulation layer 72 in the second area A2. On this basis, the pixel definition layer 80 partially covers the blocking portion 40, that is, the pixel defining portion 81 can block and limit the second encapsulation layer 72 in the second area A2, ensuring the reliability of the internal structure of the display panel.

[0149] In some embodiments, the pixel definition layer 80 extends from the first area A1 to the second area A2 , that is, the partial structure of the pixel definition layer 80 in the first area A1 is integrally connected with the partial structure of the pixel definition layer 80 in the second area A2 .

[0150] In some embodiments, the orthographic projection of the light emitting control circuit D1 on the substrate 10 is located within the orthographic projection of the pixel definition layer 80 on the substrate 10 , and / or the orthographic projection of the blocking portion 40 on the substrate 10 is located within the orthographic projection of the pixel definition layer 80 on the substrate 10 .

[0151] In the related art, the partial structure of the pixel definition layer 80 located in the first area A1 and the partial structure located in the second area A2 are disconnected from each other. In the embodiment of the present application, the pixel definition layer 80 is arranged to extend from the first area A1 to the second area A2, that is, the pixel definition layer 80 can be a whole surface structure and located in the first area A1 and the second area A2 at the same time. This design allows the pixel definition layer 80 to better cover the conductor structure below, such as the light emitting control circuit D1, thereby improving the manufacturing reliability of the display panel.

[0152] Further, the pixel definition layer 80 includes an inorganic material.

[0153] Compared with organic materials, the inherent characteristics of inorganic materials can hinder the flow of the first encapsulation layer 71 to a certain extent. Therefore, by setting the pixel definition layer 80 to include inorganic materials, it can delay the overflow of the first encapsulation layer 71, thereby facilitating the barrier 40 to be further disposed closer to the first area A1, thereby improving the narrow frame effect of the display panel. Exemplarily, the pixel definition layer 80 can include a silicon nitride material.

[0154] Second, see Fig.10 , an embodiment of the present application provides a display device, comprising a display panel in any of the aforementioned embodiments.
