[0017] As the need for larger display size increases, the problem of the frame size of the display panel becoming narrower becomes more prominent. In the related art, it is usually necessary to arrange a plurality of types of circuit configurations at the frame position of the display panel so as to satisfy the requirement for the display panel to operate normally. Due to the existence of these circuit structures, it is difficult to reduce the frame size of the display panel, and if the frame size is forcibly reduced, there are problems such as display abnormalities occurring in the display panel and a deterioration in display image quality.

[0018] 1 to 3, in a first aspect, an embodiment of the present application provides a display panel, the display panel having a first region A1, the display panel includes a substrate 10, an isolation structure 20, a light-emitting functional layer, and a first signal line 60, the isolation structure 20 is provided on one side of the substrate 10, the isolation structure 20 is surrounded by a plurality of aperture structures 21 spaced apart from each other, the light-emitting functional layer is provided on one side of the substrate 10 and is located at least in the first region A1, the light-emitting functional layer includes a plurality of light-emitting structures 31 respectively provided in the plurality of aperture structures 21, and there is at least one light-emitting structure 31 in one aperture structure 21. For example, there is one light-emitting structure 31 in one aperture structure 21, or there are a plurality of light-emitting structures 31 of the same light-emitting color in one aperture structure 21.

[0019] The first signal line 60 is disposed on one side of the isolation structure 20 along a first direction X, and the first signal line 60 is electrically connected to the isolation structure 20, and the first direction X is parallel to the plane on which the substrate 10 is disposed.

[0020] The display panel further includes a second region A2 in addition to the first region A1, the first region A1 being a display region for realizing a display effect in the display panel, the second region A2 being provided around the outer periphery of the first region A1 and mainly used for arranging the driving circuit in the display panel, and the second region A2 being a non-display region. The size and shape of the first region A1 and the second region A2 are not limited in the embodiment of the present application. For example, the first region A1 may have a rectangular structure, and the second region A2 may have a square ring structure.

[0021] The substrate 10 mainly serves as a support, and the other film layers are sequentially stacked on the substrate 10, and the term "stacked" here refers to the other film layers being sequentially stacked along the thickness direction Z of the substrate 10. Here, the substrate 10 may include a plurality of film layer structures, and the specific film layer structure of the substrate 10 is not limited in the embodiments of the present application. Note that the thickness direction Z of the other film layers located on one side of the substrate 10 is usually consistent with the thickness direction Z of the substrate 10 itself, so for convenience of explanation, the thickness direction Z of the substrate 10 or the thickness direction Z of the other film layers in the following embodiments of the present application are all shown in the same direction.

[0022] The light-emitting functional layer and the isolation structure 20 are located on the same side of the substrate 10, the light-emitting functional layer is located in the first region A1 and includes a plurality of light-emitting structures 31, and the light-emitting structures 31 are main devices for realizing light-emitting display. Here, the light-emitting structures 31 include, but are 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 hole injection layer (HIL), a hole transport layer (HTL), a light-emitting layer, an electron injection layer (EIL), and an electron transport layer (ETL) that are stacked.

[0023] Optionally, the display panel may further include a first electrode layer 40 located on a side of the light-emitting functional layer away from the substrate 10. In addition, the display panel further includes a second electrode layer 50 located on a side of the light-emitting functional layer 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 plural, the plural second electrodes 51 are provided corresponding to the light-emitting structures 31, and the first electrode 41 and the second electrode 51 jointly drive and control whether the light-emitting structures 31 emit light. Exemplarily, the first electrode 41 is a cathode, and the second electrode 51 is an anode.

[0024] The isolation structure 20 can be surrounded to form a plurality of opening structures 21, and for example, the orthogonal projection of the isolation structure 20 on the substrate 10 has a mesh structure. The plurality of light emitting structures 31 are respectively disposed within the plurality of opening structures 21, that is, the orthogonal projection of the light emitting structure 31 on the substrate 10 is disposed corresponding to the orthogonal projection of the opening structure 21 on the substrate 10, and the orthogonal projection of the light emitting structure 31 on the substrate 10 is at least partially located within the orthogonal projection of the opening structure 21 on the substrate 10. Furthermore, in the manufacturing process of the light emitting functional layer, the presence of the isolation structure 20 can cancel out a precise metal mask.

[0025] Specifically, taking the red light-emitting structure 31 as an example, in order to cancel the precise metal mask, the red light-emitting material corresponding to the red light-emitting structure 31 first falls into each opening structure 21, and then the red light-emitting material in some of the opening structures 21 is selectively etched away, and the red light-emitting material in some of the opening structures 21 is reserved to form the red light-emitting structure 31. Then, the green light-emitting material corresponding to the green light-emitting structure 31 falls into each opening structure 21, and then the green light-emitting material in some of the opening structures 21 is selectively etched away, and the green light-emitting material in some of the opening structures 21 is reserved to form the green light-emitting structure 31.

[0026] Similarly, due to the presence of the isolation structure 20, the first electrode layer 40 may include a plurality of first electrodes 41 each arranged in the opening structure 21, i.e., the multiple first electrodes 41 may be arranged corresponding to the multiple light-emitting structures 31 to realize driving control for the light-emitting structures 31.

[0027] Further optionally, the first electrode 41 may be provided in electrical communication with the isolation structure 20, i.e., a conductive material may be included within the isolation structure 20, and the first electrode 41 and the conductive material within the isolation structure 20 may be in communication with each other. In such a design, a power signal corresponding to the first electrode 41 may be transmitted through the isolation structure 20 into the first electrode 41 as required for the transmission of the power signal.

[0028] In addition, the conductive material for electrically connecting with the first electrodes 41 in the isolation structure 20 may be provided continuously, i.e., the effect of each first electrode 41 transmitting the same power signal through the isolation structure 20 can be realized. Alternatively, the conductive material for electrically connecting with the first electrodes 41 in the isolation structure 20 may be provided discontinuously or insulated from each other, i.e., at least some different first electrodes 41 may receive or transmit power signals of different voltage values ​​through the isolation structure 20, thereby realizing independent or partition control of the light emitting structures 31, which is not limited in the embodiments of the present application.

[0029] The display panel further includes a first signal line 60 for transmitting a specific signal. In the related art, a partial structure of the first signal line 60 located in the second region A2 needs to be provided in a ring-shaped structure surrounding the outer periphery of the first region A1 so that the signal in the first signal line 60 can be transmitted to different positions in the first region A1 and can help reduce voltage drop. However, such a design causes the first signal line 60 to occupy an excessive size at the frame position of the display panel, which is disadvantageous in realizing the effect of a narrow frame.

[0030] In the embodiment of the present application, the first signal line 60 is located on one side of the first region A1 along the first direction X without surrounding the first region A1, and transmits signals to different positions in the first region A1 via the isolation structure 20. Specifically, the isolation structure 20 is stretched across each position in the first region A1, and a conductive material for transmitting a specific signal is provided within the isolation structure 20.

[0031] Therefore, the first signal line 60 does not need to be provided so as to surround each first region A1, but only needs to be provided on one side of the isolation structure 20 along the first direction X and electrically connected to the isolation structure 20. In this way, the power signal located in the first signal line 60 can be transmitted to different positions in each first region A1 through the isolation structure 20, thereby satisfying the need for signal transmission. In addition, since the first signal line 60 is located on one side of the isolation structure 20 along the first direction X and does not have a ring structure, it contributes to reducing the frame size of the display panel and improves the display effect.

[0032] In addition, the specific wiring form of the first signal lines 60 is not limited to the embodiment of the present application. According to the actual situation, the first signal lines 60 may be completely located on one side of the isolation structure 20 along the first direction X, or a small number of the first signal lines 60 may be located on the other side of the isolation structure 20 along a different direction, as long as most of the first signal lines 60 are located on the same side of the isolation structure 20.

[0033] In some embodiments, as shown in Figures 1 to 3, the isolation structure 20 includes a first isolation portion 22 and a second isolation portion 23 that are stacked sequentially along a direction away from the substrate 10, and the orthogonal projection of the first isolation portion 22 on the substrate 10 is located within the orthogonal projection of the second isolation portion 23 on the substrate 10.

[0034] The specific size and shape of the first isolation portion 22 and the second isolation portion 23 are not limited in the embodiments of the present application. For example, the vertical section of the isolation structure 20 may be T-shaped. This design helps prevent the luminescent material and the electrode material from extending along the sidewall of the first isolation portion 22 to the sidewall of the second isolation portion 23 during the manufacturing process of the light emitting functional layer and the first electrode layer 40, and realizes the manufacture and mutual isolation of the light emitting structures 31 and the first electrodes 41 in different opening structures 21 without the need for a precise metal mask.

[0035] The material compositions of the first isolation portion 22 and the second isolation portion 23 are not limited in the embodiments of the present application. Both the first isolation portion 22 and the second isolation portion 23 may include a conductive material, or the first isolation portion 22 may include a conductive material and the second isolation portion 23 may include an insulating material, as long as the first electrode 41 can realize signal transmission through the isolation structure 20.

[0036] Also, at least a portion of the first signal line 60 is located within the second region A2, and the first signal line 60 may be located entirely within the second region A2, or the first signal line 60 may extend partially within the first region A1. Similarly, the isolation structure 20 may be located entirely within the first region A1, or the isolation structure 20 may extend partially within the second region A2, and the embodiments of the present application are not limited thereto.

[0037] In some embodiments, the display panel further includes a first electrode layer 40 located on the side of the light-emitting functional layer facing away from the substrate 10, the first electrode layer 40 including a plurality of first electrodes 41 arranged within a plurality of aperture structures 21, and the first electrodes 41 are arranged in electrical connection with the first signal line 60 via the isolation structure 20.

[0038] In the embodiment of the present application, the first signal line 60 is not directly connected to the first electrodes 41, but transmits a power signal to each of the first electrodes 41 through the isolation structure 20. Specifically, the isolation structure 20 itself is provided corresponding to each of the first electrodes 41, and signal transmission between the two can be realized. Therefore, the first signal line 60 does not need to be extended to the position of each of the first electrodes 41, that is, the first signal line 60 does not need to be provided so as to surround each of the first electrodes 41, but only needs to be provided on one side of the isolation structure 20 along the first direction X and electrically connected to the isolation structure 20. In this way, the power signal located in the first signal line 60 can be transmitted to each of the first electrodes 41 through the isolation structure 20, thereby satisfying the demand for signal transmission. In addition, since the first signal line 60 is located on one side of the isolation structure 20 along the first direction X and is not a ring structure, it contributes to reducing the frame size of the display panel and improves the display effect.

[0039] In some embodiments, the first isolation portion 22 comprises a conductive material, and the first electrode 41 is provided in electrical connection with the first isolation portion 22 .

[0040] The first signal line 60 can realize the transmission of a power signal to the first electrode 41 via the first isolation portion 22, where the first electrode 41 may be in direct contact with the first isolation portion 22, or the first electrode 41 may be electrically connected to the first isolation portion 22 via another conductive structure, and the embodiments of the present application are not limited thereto.

[0041] In the embodiment of the present application, by disposing a conductive material in the first isolation portion 22, the first signal line 60 can realize the transmission of a power signal to the first electrode 41 through the first isolation portion 22, thereby satisfying the demand for signal transmission. Furthermore, by providing an extension path for 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 the first signal line 60 only needs to be provided on one side of the isolation structure 20 along the first direction X, without the need to provide the first signal line 60 so as to surround the first area A1, thereby reducing the frame size of the display panel.

[0042] The positional relationship between the first signal line 60 and the first isolation portion 22 is not limited in this embodiment of the present application. In some examples, at least a portion of the first signal line 60 may contact the first isolation portion 22, i.e., the power signal in at least a portion of the first signal line 60 may be directly transmitted into the first isolation portion 22. Furthermore, when the isolation structure 20 further includes another conductive structure electrically connected to the first isolation portion 22, the first signal line 60 may contact the other conductive structure.

[0043] In some embodiments, referring to FIG. 4 , the isolation structure 20 further includes a third isolation portion 24 located on the side of the first isolation portion 22 facing the substrate 10, the third isolation portion 24 including a conductive material and being electrically connected to the first isolation portion 22.

[0044] The isolation structure 20 includes at least a first isolation portion 22, a second isolation portion 23, and a third isolation portion 24, and the size and shape of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24 are not limited in the embodiment of the present application. Exemplarily, the orthogonal projection of the first isolation portion 22 on the substrate 10 is located within the orthogonal projection of the third isolation portion 24 on the substrate 10, that is, the vertical cross-sectional shapes of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24 are U-shaped.

[0045] Similar to the first isolation portion 22, the third isolation portion 24 also includes a conductive material, and the first electrode 41 can be in direct contact with the third isolation portion 24 to realize an electrical connection with the first isolation portion 22 through the third isolation portion 24. Optionally, the first electrode 41 is overlappingly connected to the third isolation portion 24. Furthermore, the first electrode 41 may 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 41 and the isolation structure 20.

[0046] In some embodiments, the second standoff 23 comprises a conductive material.

[0047] Similar to the first isolation portion 22, the second isolation portion 23 also includes a conductive material, i.e., the second isolation portion 23 may be used to realize a signal transmission function, in which the first isolation portion 22 and the second isolation portion 23 may be electrically connected to each other, i.e., the second isolation portion 23 may be used to transmit a power signal, or the first isolation portion 22 and the second isolation portion 23 may be insulated from each other, i.e., the second isolation portion 23 may not be used to transmit a power signal, and the embodiments of the present application are not limited thereto.

[0048] Further optionally, the first isolation portion 22 is provided in electrical connection with the second isolation portion 23 , and at least a portion of the first signal line 60 is provided in contact with the second isolation portion 23 .

[0049] In this case, the first isolation part 22 may be provided in direct contact with the second isolation part 23, and in this case, the same electrical signal is transmitted to the first isolation part 22 and the second isolation part 23. In this case, the first signal line 60 and the second isolation part 23 can be contact-connected, and the power signal in the first signal line 60 is transmitted to the first isolation part 22 via the second isolation part 23, and then transmitted to the first electrode 41 via the first isolation part 22, thereby satisfying the demand for transmitting the power signal.

[0050] In some embodiments, referring to FIG. 5, the isolation structure 20 further includes a first insulating portion 25 disposed between the first isolation portion 22 and the second isolation portion 23 .

[0051] The size of the first insulating portion 25 relative to the first isolation portion 22 and the second isolation portion 23 is not limited in the embodiment of the present application. Exemplarily, the orthogonal projection of the first isolation portion 22 on the substrate 10 is located within the orthogonal projection of the first insulating portion 25 on the substrate 10, and the orthogonal projection of the first insulating portion 25 on the substrate 10 is located within the orthogonal projection of the second isolation portion 23 on the substrate 10. This further reduces the risk that the light emitting material and the electrode material extend from the sidewall of the first isolation portion 22 to the sidewall of the second isolation portion 23, which helps to improve the reliability of the manufacturing of the display panel.

[0052] Due to the presence of the first insulating portion 25, the first isolation portion 22 and the second isolation portion 23 are in an insulated state, and the power signal in the first isolation portion 22 is not transmitted to the second isolation portion 23. Based on this, the display panel can transmit other different types of signals through the second isolation 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 isolation portion 23 may be used for touch signals.

[0053] In some embodiments, the etch selectivity of the first isolation portion 22 relative to the second isolation portion 23 is greater than one.

[0054] An etching selectivity ratio refers to the relative etching rate of one material to another material under the same etching conditions. Since the etching selectivity ratio of first isolation portion 22 to second isolation portion 23 is greater than 1, the etching rate corresponding to first isolation portion 22 is greater than the etching rate of second isolation portion 23 under the same etching conditions.

[0055] Based on this, the first isolation portion 22 and the second isolation portion 23 can be manufactured and formed by the same etching process, thereby reducing the manufacturing process of the display panel and improving manufacturing efficiency. After manufacturing is completed, the orthogonal projection of the first isolation portion 22 on the substrate 10 can be positioned within the orthogonal projection of the second isolation portion 23 on the substrate 10, making it more practical.

[0056] In some embodiments, as shown in FIGS. 2 and 3, the display panel further has a second region A2, the second region A2 is arranged to surround the periphery of the first region A1, the display panel further includes a driving chip IC arranged in the second region A2 and located on one side of the isolation structure 20 along the first direction X, and the first signal line 60 is electrically connected to the driving chip IC.

[0057] The driving chip IC is a driving control element, and can realize the control of the first electrode 41. Moreover, the driving chip IC is located in the second region A2, and is located on one side of the isolation structure 20 along the first direction X. Based on this, in order to realize the electrical connection between the driving chip IC and the first electrode 41, the embodiment of the present application adds a first signal line 60 between the driving chip IC and the isolation structure 20, and the first signal line 60 is located between the driving chip IC and the isolation structure 20 along the first direction X, the driving chip IC transmits a corresponding power signal to the first signal line 60, and then transmits it to the isolation structure 20 through the first signal line 60, and finally the isolation structure 20 transmits the power signal to the first electrode 41 to realize the driving control of the first electrode 41.

[0058] 6, in some embodiments, the second region A2 includes a first sub-region A21 and a second sub-region A22 located between the driving chip IC and the isolation structure 20, and the first sub-region A21 and the second sub-region A22 are arranged side by side in the second direction Y, and the first direction X crosses the second direction Y. Here, the first signal line 60 located in the first sub-region A21 and the first signal line 60 located in the second sub-region A22 are insulated from each other.

[0059] The first sub-region A21 and the second sub-region A22 are both located between the driving chip IC and the isolation structure 20, and the specific positional relationship between the first sub-region A21 and the second sub-region A22 is not limited to the embodiment of the present application, as long as the first sub-region A21 and the second sub-region A22 are arranged side by side in the second direction Y. Optionally, the first direction X is perpendicular to the second direction Y.

[0060] A first signal line 60 is provided in both the first sub-region A21 and the second sub-region A22, and only one first signal line 60 may be provided in the first sub-region A21, or multiple first signal lines 60 may be provided in the first sub-region A21. Similarly, only one first signal line 60 may be provided in the second sub-region A22, or multiple first signal lines 60 may be provided in the second sub-region A22.

[0061] As can be seen from the above, the first signal line 60 is electrically connected to the isolation structure 20 so as to realize electrical connection with the first electrode 41 via the isolation structure 20. Based on this, the first signal line 60 located in the first sub-region A21 and the first signal line 60 located in the second sub-region A22 are insulated from each other, that is, the partial structure of the isolation structure 20 for electrically connecting with the first signal line 60 in the first sub-region A21 and the partial structure of the isolation structure 20 for electrically connecting with the first signal line 60 in the second sub-region A22 are insulated from each other, and thus the first signal line 60 located in the first sub-region A21 and the first signal line 60 located in the second sub-region A22 can separately control different first electrodes 41, which helps to improve the control accuracy.

[0062] 6, the isolation structure 20 includes a first isolation structure 26 and a second isolation structure 27 that are arranged in an insulated manner, and the first isolation structure 26 and the second isolation structure 27 are located in different sub-regions of the first region A1. The first isolation structure 26 and the second isolation structure 27 have different resistances within the same orthogonal projection area, and different first signal lines 60 are arranged to be electrically connected to the first isolation structure 26 and the second isolation structure 27, respectively.

[0063] The first isolation structure 26 and the second isolation structure 27 are provided insulated from each other, and the embodiment of the present application is not limited to the size and shape of the first isolation structure 26 and the second isolation structure 27. For example, the first isolation structure 26 may have a structure such as a stripe shape or a net shape, and the second isolation structure 27 has the same structure.

[0064] Due to factors such as the extension length and shape difference between the first isolation structure 26 and the second isolation structure 27, the electrical resistance corresponding to the first isolation structure 26 is different from the electrical resistance corresponding to the second isolation structure 27. Based on this, when power signals of the same voltage are input to the first isolation structure 26 and the second isolation structure 27, the power signals received by the different first electrodes 41 corresponding to the first isolation structure 26 and the second isolation structure 27 will differ in magnitude, which is likely to cause problems such as display unevenness on the display panel and is detrimental to the display effect.

[0065] Based on this, the embodiment of the present application installs different first signal lines 60 electrically connected to the first isolation structure 26 and the second isolation structure 27, respectively, and the driving chip IC can control the different first signal lines 60 according to the magnitude of resistance of the first isolation structure 26 and the second isolation structure 27 to input different voltages to the first isolation structure 26 and the second isolation structure 27, respectively, so that the different first electrodes 41 corresponding to the first isolation structure 26 and the second isolation structure 27 can receive accurate voltage signals, thereby improving the control accuracy of the first electrodes 41 and improving the display uniformity.

[0066] The resistance relationship between the first isolation structure 26 and the second isolation structure 27 is not limited to this embodiment of the present application. Optionally, the first isolation structure 26 and the second isolation structure 27 have different orthogonal projection areas on the substrate 10, and the resistance values ​​therebetween are different. Specifically, in general, the larger the orthogonal projection area on the substrate 10, the larger the corresponding resistance value, and the smaller the orthogonal projection area on the substrate 10, the smaller the corresponding resistance value.

[0067] In some other embodiments, the first isolation structure 26 and the second isolation structure 27 have different cross-sectional sizes, resulting in different resistances between them. Specifically, a larger cross-sectional size typically results in a lower resistance, and a smaller cross-sectional size typically results in a higher resistance.

[0068] In addition, the insulation manner between the first isolation structure 26 and the second isolation structure 27 is not limited to the embodiment of the present application. Optionally, the first isolation structure 26 is spaced apart from the second isolation structure 27. Further optionally, the isolation structure 20 further includes an insulating structure 28 located between the first isolation structure 26 and the second isolation structure 27.

[0069] In some embodiments, as shown in FIG. 3, the display panel further includes a first sealing layer 71 provided on a side of the first electrode layer 40 facing away from the substrate 10, and the first sealing layer 71 includes a plurality of first sealing portions 711 each provided within the opening structure 21.

[0070] The first encapsulation layer 71 is located on the side of the first electrode layer 40 away from the substrate 10, i.e., on the light output side of the light emitting structure 31. The first encapsulation layer 71 may play a role of encapsulation protection for the light emitting structure 31. Due to the presence of the isolation structure 20, the manufactured first encapsulation layer 71 may have a plurality of first encapsulation parts 711 corresponding to the light emitting structures 31 and located in the opening structure 21, and each first encapsulation part 711 plays an independent encapsulation role for each light emitting structure 31, thereby improving the encapsulation protection effect for the light emitting structures 31.

[0071] The embodiment of the present application is not limited to a material composition of the first sealing layer 71. Exemplarily, the first sealing layer 71 includes an inorganic material.

[0072] In some embodiments, the display panel further includes a second sealing layer 72 located on the side of the first sealing layer 71 facing away from the substrate 10, and a third sealing layer 73 located on the side of the second sealing layer 72 facing away from the substrate 10.

[0073] The first sealing layer 71, the second sealing layer 72 and the third sealing layer 73 can jointly form a thin film sealing structure, which can further reduce the risk of moisture, oxygen, etc. invading the light emitting structure 31, and improve the reliability of the display panel. The material composition of the second sealing layer 72 and the third sealing layer 73 is not limited to the embodiment of the present application. Optionally, the first sealing layer 71 and the third sealing layer 73 both include inorganic materials, and the second sealing layer 72 includes organic materials, so that the first sealing layer 71 and the second sealing layer 72 can play a positional limiting role for the second sealing layer 72 to a certain extent, and can improve the reliability of the structure.

[0074] Unlike the first encapsulation layer 71, the second encapsulation layer 72 and the third encapsulation layer 73 may be full-surface structures, i.e., the orthogonal projection of the second encapsulation layer 72 on the substrate 10 and the second encapsulation layer 72 may simultaneously cover the orthogonal projection of the multiple light-emitting structures 31 on the substrate 10.

[0075] In some embodiments, referring to FIGS. 2, 3 and 7, the display panel further includes a blocking portion 90 arranged in the second region A2, and the blocking portion 90 is arranged such that a normal projection of the structure on the substrate 10 located on both sides of the first region A1 along the second direction Y does not overlap with a normal projection of the first signal line 60 on the substrate 10, and the first direction X intersects with the second direction Y.

[0076] The blocking portion 90 is located in the second region A2, and is usually located at the edge position of the display panel. As can be seen from the above, the second sealing layer 72 contains an organic material, and the organic material contained in the second sealing layer 72 usually has a certain fluidity. In order to reduce the risk of the organic material in the second sealing layer 72 overflowing, the blocking portion 90 is usually provided at the edge position of the display panel. The presence of the blocking portion 90 can reduce the risk of overflow and improve the reliability of the display panel.

[0077] For example, the second region A2 includes left and right frames and a lower frame, and when the first signal line 60 is located in the lower frame and is not provided in the left and right frames, the second region A2 is provided so that the orthogonal projection of the blocking portion 90 located in the left and right frames on the substrate 10 does not overlap with the orthogonal projection of the first signal line 60 on the substrate 10.

[0078] Furthermore, since the first signal line 60 is located on one side of the isolation structure 20 only along the first direction X and is not provided so as to surround the periphery of the isolation structure 20, the first signal line 60 does not exist in some positions in the second region A2, for example, in local regions in the second region A2 located on both sides of the first region A1 along the second direction Y. Based on this, the orthogonal projection on the substrate 10 of the structure in which the blocking portion 90 is located on both sides of the first region A1 along the second direction Y is distributed in a position shifted from the orthogonal projection on the substrate 10 of the first signal line 60, that is, the first signal line 60 does not affect the layout design of the blocking portion 90, which helps to reduce the risk of physical interference between them.

[0079] In some embodiments, the first sealing layer 71 and the blocking portion 90 are provided so that their orthogonal projections on the substrate 10 do not overlap.

[0080] Due to the presence of the isolation structure 20, the first sealing portion 711 in the first sealing layer 71 falls into the opening structure 21 and is provided corresponding to the light emitting structure 31. Therefore, most of the first sealing layer 71 is located in the first region A1, and the first sealing layer 71 is located near the boundary between the first region A1 and the second region A2. Since the second sealing layer 72 usually covers the first region A1 or more and enters the second region A2, the influence of the positional restriction of the first sealing layer 71 on the second sealing layer 72 in the second region A2 is reduced.

[0081] Based on this, the second sealing layer 72 needs to achieve positional restriction via a structure other than the first sealing layer 71 in the display panel; however, since the blocking portion 90 and the first sealing layer 71 are arranged so as not to overlap on the substrate 10, the presence of the blocking portion 90 serves to restrict the position of the second sealing layer 72, thereby reducing the risk of the second sealing layer 72 overflowing.

[0082] In some embodiments, as shown in FIG. 7, the third sealing layer 73 is located on the side of the blocking portion 90 away from the substrate 10 and covers at least a portion of the structure of the blocking portion 90 .

[0083] Unlike the first sealing layer 71, the third sealing layer 73 may have an entire structure, and the third sealing layer 73 may be partially located in the second region A2. Based on this, in the embodiment of the present application, the third sealing layer 73 covers at least a part of the structure of the blocking portion 90, so that the third sealing layer 73 can cooperate with the blocking portion 90 to perform a position limiting function for the second sealing layer 72.

[0084] 8, in some embodiments, the display panel further includes a gate electrode driving circuit located in the second region A2, and at least a portion of the blocking portion 90 is located on a side of the gate electrode driving circuit away from the substrate 10. Here, the gate electrode driving circuit may include a light emission control circuit D2.

[0085] The display panel includes multiple other film layer structures, some of which have a certain fluidity due to factors such as material composition. In order to achieve an effective blocking effect on such film layer structures, the display panel in the embodiment of the present application is further provided with a blocking section 90, which is located in the second area A2 and mainly serves to block the flow of some of the film layers away from the first area A1 of the blocking section 90, thereby improving the reliability of the internal structure of the display panel.

[0086] Generally, the film layer structure having fluidity has a certain thickness size, and the thickness of the film layer structure of this type decreases gradually as it approaches the edge position of the display panel. Based on this, if the blocking part 90 is located close to the first area A1, it is necessary to increase the size of the blocking part 90 in the thickness direction Z to meet the blocking needs, which is disadvantageous to the thickness design of the entire display panel. Therefore, the blocking part 90 is usually located far from the first area A1, and further, in the related art, the blocking part 90 is located on the side away from the first area A1 of the light emission control circuit D2.

[0087] The gate electrode driving circuit is located in the second region A2, and the blocking portion 90 is located on the side of the gate electrode driving circuit away from the first region A1, i.e., the blocking portion 90 and the gate electrode driving circuit are arranged parallel to each other and spaced apart in the planar direction in which the substrate 10 is located.

[0088] In the embodiment of the present application, the isolation structure 20 is surrounded to form a plurality of opening structures 21, and at least some of the opening structures 21 can accommodate a film layer structure having fluidity, so that the presence of the isolation structure 20 can reduce the thickness size of some of the film layers in the second region A2. Based on this, in the embodiment of the present application, the blocking portion 90 can be appropriately moved in a direction approaching the first region A1 without excessively increasing the height of the blocking portion 90, and at least a part of it can be positioned on the side away from the substrate 10 of the gate electrode driving circuit, thereby solving the problem that the distance between the blocking portion 90 and the first region A1 is too large, resulting in an excessively large frame size of the display panel, i.e., helping to reduce the frame size of the display panel and improve the display effect.

[0089] Furthermore, at least a part of the blocking portion 90 may be selectively located on the side away from the substrate 10 of the light-emission control circuit D2.

[0090] In addition, the blocking portion 90 may be located completely on the side away from the substrate 10 of the light-emitting control circuit D2, or a part of the blocking portion 90 may be located on the side away from the substrate 10 of the light-emitting control circuit D2 and another part may be located on the side away from the first region A1 of the light-emitting control circuit D2, or a part of the blocking portion 90 may be located on the side away from the substrate 10 of the light-emitting control circuit D2 and another part may be located on the side away from the first region A1 of the light-emitting control circuit D2, and the embodiment of the present application is not limited thereto. Here, since the light-emitting control circuit D2 itself has a certain thickness size, the presence of the light-emitting control circuit D2 contributes to reducing the height size of at least a part of the structure of the blocking portion 90 located on the side away from the substrate 10 of the light-emitting control circuit D2, thereby reducing the material cost corresponding to the blocking portion 90 and providing higher practicality.

[0091] In some embodiments, the display panel further includes a second encapsulation layer 72 disposed on a side of the light-emitting functional layer away from the substrate 10, the second encapsulation layer 72 including an organic material. Furthermore, the second encapsulation layer 72 may be partially located within the aperture structure 21.

[0092] The second sealing layer 72 is located on the side of the light-emitting functional layer away from the substrate 10, i.e., on the light-emitting surface side of the light-emitting structure 31. A part of the second sealing layer 72 is located in the first region A1, and the other part is located in the second region A2. The second sealing layer 72 mainly serves to seal and protect the light-emitting structure 31, reducing the risk of moisture, oxygen, etc. entering the light-emitting structure 31 and improving the light-emitting reliability of the display panel.

[0093] The second sealing layer 72 contains an organic material and has a certain fluidity, but the second sealing layer 72 can be partially located within the opening structure 21, so that the opening structure 21 can have a certain overflow accommodation effect on the second sealing layer 72, thereby reducing the thickness size of the second sealing layer 72 in the second region A2, and thus reducing the distance between the blocking portion 90 and the first region A1, and at least a part of it can be located on the side away from the substrate 10 of the light-emitting control circuit D2, which is helpful in realizing the narrow-bezel display effect of the display panel.

[0094] In some embodiments, as shown in FIG. 8, the display panel further includes a first sealing layer 71 disposed between the second sealing layer 72 and the light-emitting functional layer, and a third sealing layer 73 located on the side of the second sealing layer 72 away from the substrate 10, and the first sealing layer 71 and the third sealing layer 73 include inorganic materials.

[0095] The first sealing layer 71 and the third sealing layer 73 are located on both sides of the second sealing layer 72 in the thickness direction Z, and the first sealing layer 71, the second sealing layer 72 and the third sealing layer 73 jointly form a thin film sealing structure to improve the sealing and protecting effect on the light emitting functional layer. Here, the first sealing layer 71 and the third sealing layer 73 both contain inorganic materials, and the first sealing layer 71 and the third sealing layer 73 can perform a certain position limiting and blocking function for the second sealing layer 72.

[0096] Further optionally, the first sealing layer 71 includes a plurality of first sealing portions 711 each disposed within the opening structure 21, and the first sealing portions 711 and the blocking portion 90 are disposed parallel to each other with a gap therebetween in the direction in which the substrate 10 is located.

[0097] Due to the presence of the isolation structure 20, the sealing material for forming the first sealing portion 711 also falls into the opening structure 21, thereby forming a plurality of first sealing portions 711 corresponding to the opening structure 21, where the different first sealing portions 711 are spaced apart from each other.

[0098] In the embodiment of the present application, the presence of the blocking portion 90 serves to prevent overflow into the second sealing layer 72, thereby reducing the risk of the second sealing layer 72 extending away from the first region A1 of the blocking portion 90 and improving the sealing reliability of the display panel.

[0099] In some embodiments, the third sealing layer 73 is partially located on the side of the blocking portion 90 away from the substrate 10, i.e., the third sealing layer 73 extends from the first region A1 to the second region A2 and can cover at least a portion of the structure of the blocking portion 90.

[0100] In such a design, the blocking portion 90 cooperates with the third sealing layer 73 to jointly perform the role of limiting the position and blocking the second sealing layer 72, further reducing the risk of the second sealing layer 72 extending away from the first region A1, and improving the sealing reliability of the display panel.

[0101] In some embodiments, as shown in FIG. 8, the gate electrode driving circuit further includes a scanning driving circuit D1 located between the light emitting control circuit D2 and the first region A1, and the blocking portion 90 is located on the side of the scanning driving circuit D1 away from the first region A1, or the blocking portion 90 is located on the side of the scanning driving circuit D1 away from the substrate 10.

[0102] The scanning driving circuit D1 and the light emitting control circuit D2 may both include a multi-stage shift register cascade-connected to each other, and the multi-stage shift register can sequentially scan the pixel circuits of each row located in the first area A1 and sequentially output an on level to meet display needs.

[0103] The scanning drive circuit D1 and the light emission control circuit D2 are both located in the second region A2, and the scanning drive circuit D1 is located on the side closer to the first region A1 of the light emission control circuit D2. Here, based on the short distance between the scanning drive circuit D1 and the first region A1, in order to ensure the blocking effect of the blocking unit 90 against the overflow to the first sealing layer 71, in the embodiment of the present application, the blocking unit 90 is further provided on the side where the scanning drive circuit D1 is away from the first region A1, that is, the distance between the blocking unit 90 and the first region A1 is greater than the distance between the scanning drive circuit D1 and the first region A1. As a result, a certain distance size can be secured between the blocking unit 90 and the first region A1, and therefore the blocking effect of the blocking unit 90 against the overflow to the first sealing layer 71 can be improved without increasing the height size of the blocking unit 90.

[0104] Alternatively, when the opening structure 21 can accommodate a large amount of organic material in the first sealing layer 71, the blocking portion 90 can be located on the side of the scanning driving circuit D1 away from the substrate 10, so as to further realize a narrower bezel of the display panel and improve the display effect.

[0105] In some embodiments, the orthogonal projection of the substrate and the orthogonal projection of the light emission control circuit D2 on the substrate at least partially overlap, or the orthogonal projection of the blocking portion 90 on the substrate and the orthogonal projection of the light emission control circuit D2 on the substrate are offset from and adjacent to each other.

[0106] In some embodiments, as shown in FIG. 8, the display panel further includes a second insulating portion 91 disposed between the light emission control circuit D2 and at least a portion of the blocking portion 90. In the embodiment shown in FIG.

[0107] The second insulating portion 91 may cover at least a portion of the structure of the light-emission control circuit D2. For example, the orthogonal projection of the second insulating portion 91 on the substrate covers the orthogonal projection of the light-emission control circuit D2 on the substrate. As a result, after the manufacture of the light-emission control circuit D2 is completed, the second insulating portion 91 serves to isolate the light-emission control circuit D2 from the air, and during the manufacturing process of subsequent metal layers, etc., the second insulating portion 91 serves to protect the light-emission control circuit D2, thereby reducing the risk of over-etching of the light-emission control circuit D2 and improving reliability.

[0108] Furthermore, the second insulating section 91 can improve the operational reliability of the light-emission control circuit D2 by insulating and separating the blocking section 90 from the light-emission control circuit D2. As can be seen from the above, the blocking section 90 may be located completely on the side of the light-emission control circuit D2 that is away from the substrate 10, or a part of the blocking section 90 may be located on the side of the light-emission control circuit D2 that is away from the substrate 10, and the other part may be located on the side of the light-emission control circuit D2 that is away from the first region A1. In view of this, the second insulating section 91 may be located completely on the side of the light-emission control circuit D2 that is away from the substrate 10, or a part of the second insulating section 91 may be located on the side of the light-emission control circuit D2 that is away from the substrate 10, and the other part may be located on the side of the light-emission control circuit D2 that is away from the first region A1.

[0109] When the blocking portion 90 is located on the side away from the substrate 10 of the light-emitting control circuit D2, the second insulating portion 91 can increase the distance between the blocking portion 90 and the substrate 10, thereby reducing the height size required for the blocking portion 90 and the corresponding material costs, and making it more practical.

[0110] In some selectable embodiments, the orthogonal projection of the blocking portion 90 on the substrate 10 is located within the orthogonal projection of the second insulating portion 91 on the substrate 10. This further improves the insulating effect of the second insulating portion 91 between the blocking portion 90 and the light-emission control circuit D2, thereby improving reliability. In addition, the presence of the second insulating portion 91 allows the distance between the blocking portion 90 and the substrate 10 to be increased, thereby reducing the height of the blocking portion 90 and reducing the material cost corresponding to the blocking portion 90.

[0111] Further optionally, the orthogonal projection of the blocking portion 90 on the substrate 10 is located within the orthogonal projection of the light emission control circuit D2 on the substrate 10.

[0112] 9, in some embodiments, the second insulating portion 91 extends from the first region A1 into the second region A2, and the orthogonal projection of the second insulating portion 91 on the substrate 10 covers the orthogonal projection of the light emission control circuit D2 on the substrate 10. That is, the second insulating portion 91 is located in a partial structure in the first region A1, and the second insulating portion 91 is integrally connected to a partial structure located in the second region A2.

[0113] In the practice of the present application, the second insulating portion 91 extends from the first region A1 into the second region A2, so that the second insulating portion 91 can not only provide insulation between different conductive structures in the first region A1, but also provide a cover protection for the light-emitting control circuit D2 in the second region A2, thereby improving the reliability of the display panel. Optionally, the second insulating portion 91 can also be a planarizing layer for other purposes, which can provide a planarized surface, thereby reducing the difficulty of subsequent manufacturing of the display panel and improving the manufacturing precision of the display panel, and thus having higher practicality.

[0114] In some embodiments, referring to FIG. 10, the blocking portion 90 includes a plurality of blocking posts 92 spaced apart, at least some of the blocking posts 92 being located on the side of the light emission control circuit D2 away from the substrate 10.

[0115] From the above, the presence of the isolation structure 20 allows the distance between the blocking portion 90 and the first region A1 to be appropriately small, and at least a part of the blocking portion 90 is located on the side of the light-emitting control circuit D2 that is away from the substrate 10. Based on this, and on the premise of meeting the need for a narrow frame of the display panel, the blocking portion 90 is provided with a plurality of blocking pillars 92 spaced apart from each other, and each blocking pillar 92 serves to prevent overflow from the first sealing layer 71, thereby further reducing the tendency of the first sealing layer 71 to move away from the substrate 10 of the blocking portion 90, and improving the sealing reliability.

[0116] In addition, the positional relationship between each blocking column 92 and the light-emission control circuit D2 is not limited to the embodiment of the present application. For example, at least some of the blocking columns 92 may be located on the side of the light-emission control circuit D2 that is farther from the substrate 10, or some of the blocking columns 92 may be located on the side of the light-emission control circuit D2 that is farther from the first area A1, or some of the blocking columns 92 may be located on the side close to the first area A1 of the light-emission control circuit D2.

[0117] In some selectable embodiments, each blocking post 92 is located on the side of the light-emitting control circuit D2 that is farther from the substrate 10, which is advantageous for improving the pitch between the blocking posts 92 and the substrate 10 in the thickness direction Z, so as to reduce the overall height of the blocking portion 90, thereby reducing the material cost corresponding to the blocking posts 92 and having higher practicality. Of course, in some other embodiments, only a part of the blocking posts 92 may be located on the side of the light-emitting control circuit D2 that is farther from the substrate 10.

[0118] In addition, the number of blocking posts 92 is not limited in the embodiment of the present application. Optionally, the number of blocking posts 92 is greater than 2. Exemplarily, the number of blocking posts 92 is 3, 4, 5, etc.

[0119] In some embodiments, referring to FIG. 7, the display panel further includes an emission control circuit D2 located in the second region A2, and the emission control circuit D2 and the blocking unit 90 are both located on the substrate 10, and the emission control circuit D2 and the blocking unit 90 are arranged adjacent to each other, that is, there is no first signal line 60 between the emission control circuit D2 and the blocking unit 90.

[0120] 11, in some embodiments, the display panel further includes a light-emitting control circuit D2 located in the second area A2, and at least a portion of the blocking portion 90 is located on a side of the light-emitting control circuit D2 that is away from the substrate 10. For example, the entire blocking portion 90 is located on a side of the light-emitting control circuit D2 that is away from the substrate 10, or a portion of the blocking portion 90 is located on a side of the light-emitting control circuit D2 that is away from the substrate 10, and the other portion of the blocking portion 90 is located on the substrate 10. There may be a plurality of blocking portions 90, and at least a portion of the blocking portion 90 closest to the first area A1 is located on a side of the light-emitting control circuit D2 that is away from the substrate 10.

[0121] The light-emitting control circuit D2 is located in the second area A2, and the light-emitting control circuit D2 may include a multi-stage shift register cascaded to each other, and the multi-stage shift register can sequentially scan the pixel circuits of each row located in the first area A1 and sequentially output an on level to meet display needs.

[0122] In the related art, taking into consideration the fluidity of the second sealing layer 72, the blocking portion 90 usually needs to be spaced farther from the first region A1 so that the blocking portion 90 of a certain height size can provide an effective blocking effect on the second sealing layer 72. Therefore, the blocking portion 90 is usually located on the side away from the first region A1 of the scanning driving circuit D1, which similarly affects the frame size of the display panel and is detrimental to the display effect.

[0123] In the embodiment of the present application, due to the presence of the isolation structure 20, a portion of the second sealing layer 72 falls into the opening structure 21, so that the opening structure 21 can have a certain overflow effect on the second sealing layer 72. On this basis, even if the distance between the blocking portion 90 and the first area A1 in the first direction X is reduced, the blocking portion 90 can still have an effective blocking effect on the second sealing layer 72 and reduce the risk of overflow. Therefore, in the embodiment of the present application, the blocking portion 90 is provided so that at least a portion of it is located on the side away from the substrate 10 of the light-emission control circuit D2.

[0124] In such a design, the blocking portion 90 can effectively block the second sealing layer 72, reduce the risk of overflow of the second sealing layer 72, and improve the reliability of the sealing. At the same time, it contributes to reducing the distance between the blocking portion 90 and the first area A1, thereby reducing the impact of the blocking portion 90 on the frame size and further improving the narrow frame effect.

[0125] In some embodiments, the display panel further includes a second insulating part 91 located between the blocking part 90 and the light emission control circuit D2. The second insulating part 91 may cover at least a part of the structure of the light emission control circuit D2, so that after the manufacture of the light emission control circuit D2 is completed, the second insulating part 91 serves to isolate the light emission control circuit D2 from the air, and serves to protect the light emission control circuit D2 during the subsequent manufacturing process of metal layers, etc., thereby reducing the risk of over-etching the light emission control circuit D2 and improving reliability.

[0126] Furthermore, in the embodiment of the present application, the second insulating section 91 insulates and separates the blocking section 90 from the light-emission control circuit D2, thereby improving the operational reliability of the light-emission control circuit D2. Here, the second insulating section 91 may be located completely on the side of the light-emission control circuit D2 that is away from the substrate 10, or the second insulating section 91 may be located partially on the side of the light-emission control circuit D2 that is away from the first region A1.

[0127] In addition, when the blocking portion 90 is located on the side away from the substrate 10 of the light-emitting control circuit D2, the second insulating portion 91 can increase the distance between the blocking portion 90 and the substrate 10, thereby reducing the height size required for the blocking portion 90 and the corresponding material costs, and making it more practical.

[0128] In some embodiments, the display panel further includes a pixel definition layer 80 on the substrate 10 side of the isolation structure 20, the pixel definition layer 80 including a pixel defining portion 81 and a pixel aperture 82 surrounded by the pixel defining portion 81, and the light-emitting structure 31 is at least partially located within the pixel aperture 82.

[0129] The pixel definition layer 80 includes a pixel definition portion 81 and a pixel opening 82, and the pixel opening 82 is provided corresponding to the opening structure 21. For example, the orthogonal projection of the pixel opening 82 on the substrate 10 may be located within the orthogonal projection of the opening structure 21 on the substrate 10, and partial structures in the light-emitting structure 31 and the first electrode 41 may be located within the pixel opening 82.

[0130] 10 , the display panel further includes a pixel defining layer 80, and the isolation structure 20 is disposed on a side of the pixel defining layer 80 facing away from the substrate 10 or in an aperture in the pixel defining layer 80, which may be a through-hole or a blind hole in the pixel defining layer 80. The pixel defining layer 80 includes a pixel defining portion 81 and a pixel aperture 82 surrounded by the pixel defining portion 81, and the light emitting structure 31 is at least partially located within the pixel aperture 82.

[0131] The pixel definition layer 80 includes a pixel definition portion 81 and a pixel opening 82, and the pixel opening 82 is provided corresponding to the opening structure 21. For example, the orthogonal projection of the pixel opening 82 on the substrate 10 may be located within the orthogonal projection of the opening structure 21 on the substrate 10, and partial structures in the light-emitting structure 31 and the first electrode 41 may be located within the pixel opening 82.

[0132] In some embodiments, portions of pixel defining layer 80 are located on the side of blocking portion 90 away from substrate 10 .

[0133] For the above reasons, due to the presence of isolation structure 20, first sealing layer 71 is stopped near the boundary between first region A1 and second region A2, and therefore first sealing layer 71 cannot provide an effective blocking effect for second sealing layer 72 in second region A2. Based on this, a part of pixel definition layer 80 is provided to cover blocking portion 90, i.e., pixel definition portion 81 plays a role in blocking and limiting the position of second sealing layer 72 in second region A2, thereby ensuring the reliability of the internal structure of the display panel.

[0134] In some embodiments, the pixel definition layer 80 extends from the first region A1 to the second region A2, i.e. the substructure in which the pixel definition layer 80 is located in the first region A1 is integrally connected to the substructure in which the pixel definition layer 80 is located in the second region A2.

[0135] In some embodiments, the orthogonal projection of the emission control circuit D2 on the substrate 10 is located within the orthogonal projection of the pixel definition layer 80 on the substrate 10, and / or the orthogonal projection of the blocking portion 90 on the substrate 10 is located within the orthogonal projection of the outer edge of the pixel definition layer 80 on the substrate 10.

[0136] In the related art, the partial structure of the pixel definition layer 80 located in the first region A1 and the partial structure located in the second region A2 are separated from each other. In the embodiment of the present application, the pixel definition layer 80 is provided to extend from the first region A1 to the second region A2, that is, the pixel definition layer 80 has a full-surface structure and can be located between the first region A1 and the second region A2. With such a design, the pixel definition layer 80 can better cover the underlying conductor structures such as the light-emitting control circuit D2, and the reliability of the manufacturing of the display panel can be improved.

[0137] Furthermore, the pixel defining layer 80 comprises an inorganic material.

[0138] Compared with organic materials, the self-characteristics of inorganic materials can act to inhibit a certain flow in the first sealing layer 71, so that the pixel definition layer 80 containing an inorganic material can act to delay overflow of the first sealing layer 71, and the blocking portion 90 can be disposed closer to the first area A1, thereby improving the narrow frame effect of the display panel. Exemplarily, the pixel definition layer 80 may include a silicon nitride material.

[0139] In a second aspect, as shown in Fig. 8, an embodiment of the present application provides a display panel, the display panel has a first region A1 and a second region A2 surrounding the first region A1, the display panel includes a substrate 10, an isolation structure 20, a light-emitting functional layer, a gate electrode driving circuit, and a blocking section 90, the isolation structure 20 is provided on one side of the substrate 10, the isolation structure 20 forms a plurality of aperture structures 21 spaced apart from each other, the light-emitting functional layer is provided on one side of the substrate 10 and is located in the first region A1, the light-emitting functional layer includes a plurality of light-emitting structures 31 respectively provided in the plurality of aperture structures 21, and there is at least one light-emitting structure 31 in one aperture structure 21. For example, there is one light-emitting structure 31 in one aperture structure 21, or there are a plurality of light-emitting structures 31 of the same emission color in one aperture structure 21.

[0140] The gate electrode driving circuit is located in the second region A2, the blocking portion 90 is provided in the second region A2, and at least a part of the blocking portion 90 is located on the side of the gate electrode driving circuit away from the substrate 10. Here, the gate electrode driving circuit may include a light emission control circuit D2. An orthogonal projection of at least a part of the blocking portion 90 on the substrate 10 overlaps with an orthogonal projection of the gate electrode driving circuit on the substrate.

[0141] The display panel has at least two regions: a first region A1 which is a display region for realizing a display effect in the display panel, and a second region A2 which is surrounded on the outer periphery of the first region A1 and is mainly used for arranging a driving circuit in the display panel, and the second region A2 is a non-display region. The size and shape of the first region A1 and the second region A2 are not limited in the embodiment of the present application. For example, the first region A1 may have a square structure, and the second region A2 may have a square structure with rounded corners.

[0142] The substrate 10 mainly plays a supporting role, and the other film layers are sequentially stacked on the substrate 10, and the term "stacked" refers to the other film layers being sequentially stacked along the thickness direction Z of the substrate 10. The substrate 10 may include a plurality of film layer structures, and the specific film layer structure of the substrate 10 is not limited to the embodiments of the present application. Note that the thickness direction Z of the other film layers located on the substrate 10 side is usually consistent with the thickness direction Z of the substrate 10 itself, so for convenience of explanation, the thickness direction Z of the substrate 10 or the thickness direction Z of the other film layers in the following embodiments of the present application are all shown in the same direction.

[0143] The light-emitting functional layer and the isolation structure 20 are located on the same side of the substrate 10, the light-emitting functional layer is located in the first region A1 and includes a plurality of light-emitting structures 31, and the light-emitting structures 31 are main devices for realizing light-emitting display. Here, the light-emitting structures 31 include, but are 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 hole injection layer (HIL), a hole transport layer (HTL), a light-emitting layer, an electron injection layer (EIL), and an electron transport layer (ETL) that are stacked.

[0144] Optionally, the display panel may further include a first electrode layer 40 located on a side of the light-emitting functional layer away from the substrate 10. In addition, the display panel further includes a second electrode layer 50 located on a side of the light-emitting functional layer 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 plural, the plural second electrodes 51 are provided corresponding to the light-emitting structures 31, and the first electrode 41 and the second electrode 51 jointly drive and control whether the light-emitting structures 31 emit light. Exemplarily, the first electrode 41 is a cathode, and the second electrode 51 is an anode.

[0145] The isolation structure 20 can be surrounded to form a plurality of opening structures 21, and for example, the isolation structure 20 has a net-like structure in the orthogonal projection on the substrate 10. The plurality of light-emitting structures 31 are respectively provided within the plurality of opening structures 21, that is, the orthogonal projection of the light-emitting structure 31 on the substrate 10 is provided corresponding to the orthogonal projection of the opening structure 21 on the substrate 10, and the orthogonal projection of the light-emitting structure 31 on the substrate 10 is at least partially located within the orthogonal projection of the opening structure 21 on the substrate 10. Furthermore, in the manufacturing process of the light-emitting functional layer, the presence of the isolation structure 20 can cancel a precise metal mask.

[0146] Specifically, taking the red light-emitting structure 31 as an example, in order to cancel the precise metal mask, the red light-emitting material corresponding to the red light-emitting structure 31 first falls into each opening structure 21, and then the red light-emitting material in some of the opening structures 21 is selectively etched away, and the red light-emitting material in some of the opening structures 21 is reserved to form the red light-emitting structure 31. Then, the green light-emitting material corresponding to the green light-emitting structure 31 falls into each opening structure 21, and then the green light-emitting material in some of the opening structures 21 is selectively etched away, and the green light-emitting material in some of the opening structures 21 is reserved to form the green light-emitting structure 31.

[0147] Similarly, due to the presence of the isolation structure 20, the first electrode layer 40 may include a plurality of first electrodes 41 each arranged in the opening structure 21, i.e., the multiple first electrodes 41 may be arranged corresponding to the multiple light-emitting structures 31 to realize driving control for the light-emitting structures 31.

[0148] The display panel includes multiple other film layer structures, some of which have a certain fluidity due to factors such as material composition. In order to achieve an effective blocking effect on such film layer structures, the display panel in the embodiment of the present application is further provided with a blocking section 90, which is located in the second area A2 and mainly serves to block the flow of some of the film layers away from the first area A1 of the blocking section 90, thereby improving the reliability of the internal structure of the display panel.

[0149] Generally, the film layer structure having fluidity has a certain thickness size, and the thickness of the film layer structure of this type decreases gradually as it approaches the edge position of the display panel. Based on this, if the blocking part 90 is located close to the first area A1, it is necessary to increase the size of the blocking part 90 in the thickness direction Z to meet the blocking needs, which is disadvantageous to the thickness design of the entire display panel. Therefore, the blocking part 90 is usually located far from the first area A1, and further, in the related art, the blocking part 90 is located on the side away from the first area A1 of the light emission control circuit D2.

[0150] The gate electrode driving circuit is located in the second region A2, and the blocking portion 90 is located on the side of the gate electrode driving circuit away from the first region A1, i.e., the blocking portion 90 and the gate electrode driving circuit are provided in parallel with a gap in the planar direction in which the substrate 10 is located. The orthogonal projection of the blocking portion 90 on the substrate 10 is provided adjacent to the orthogonal projection of the gate electrode driving circuit on the substrate 10.

[0151] In the embodiment of the present application, the isolation structure 20 is surrounded to form a plurality of opening structures 21, and at least some of the opening structures 21 can accommodate a film layer structure having fluidity, so that the presence of the isolation structure 20 can reduce the thickness size of some of the film layers in the second region A2. Based on this, in the embodiment of the present application, the blocking portion 90 can be appropriately moved in a direction approaching the first region A1 without excessively increasing the height of the blocking portion 90, and at least a part of it can be positioned on the side away from the substrate 10 of the gate electrode driving circuit, thereby solving the problem that the distance between the blocking portion 90 and the first region A1 is too large, resulting in an excessively large frame size of the display panel, i.e., helping to reduce the frame size of the display panel and improve the display effect.

[0152] Furthermore, at least a part of the blocking portion 90 is selectively located on the side away from the substrate 10 of the light-emission control circuit D2.

[0153] In addition, the blocking portion 90 may be located completely on the side away from the substrate 10 of the light-emitting control circuit D2, or a part of the blocking portion 90 may be located on the side away from the substrate 10 of the light-emitting control circuit D2 and another part may be located on the side away from the first region A1 of the light-emitting control circuit D2, or a part of the blocking portion 90 may be located on the side away from the substrate 10 of the light-emitting control circuit D2 and another part may be located on the side away from the first region A1 of the light-emitting control circuit D2, and the embodiment of the present application is not limited thereto. Here, since the light-emitting control circuit D2 itself has a certain thickness size, the presence of the light-emitting control circuit D2 contributes to reducing the height size of at least a part of the structure of the blocking portion 90 located on the side away from the substrate 10 of the light-emitting control circuit D2, thereby reducing the material cost corresponding to the blocking portion 90 and providing higher practicality.

[0154] In some embodiments, the display panel further includes a second encapsulation layer 72 disposed on a side of the light-emitting functional layer away from the substrate 10 , the second encapsulation layer 72 including an organic material, and a portion located within the aperture structure 21 .

[0155] The second sealing layer 72 is located on the side of the light-emitting functional layer away from the substrate 10, i.e., on the light-emitting surface side of the light-emitting structure 31. A part of the second sealing layer 72 is located in the first region A1, and the other part is located in the second region A2. The second sealing layer 72 mainly serves to seal and protect the light-emitting structure 31, reducing the risk of moisture, oxygen, etc. entering the light-emitting structure 31 and improving the light-emitting reliability of the display panel.

[0156] The second sealing layer 72 contains an organic material and has a certain fluidity, but the second sealing layer 72 can be partially located within the opening structure 21, so that the opening structure 21 can have a certain overflow accommodation effect on the second sealing layer 72, thereby reducing the thickness size of the second sealing layer 72 in the second region A2, and thus reducing the distance between the blocking portion 90 and the first region A1, and at least a part of it can be located on the side away from the substrate 10 of the light-emitting control circuit D2, which is helpful in realizing the narrow-bezel display effect of the display panel.

[0157] In some embodiments, the display panel further includes a first sealing layer 71 disposed between the second sealing layer 72 and the light-emitting functional layer, and a third sealing layer 73 located on the side of the second sealing layer 72 away from the substrate 10, and the first sealing layer 71 and the third sealing layer 73 include inorganic materials.

[0158] The first sealing layer 71 and the third sealing layer 73 are located on both sides of the second sealing layer 72 in the thickness direction Z, and the first sealing layer 71, the second sealing layer 72 and the third sealing layer 73 jointly form a thin film sealing structure to improve the sealing and protecting effect on the light emitting functional layer. Here, the first sealing layer 71 and the third sealing layer 73 both contain inorganic materials, and the first sealing layer 71 and the third sealing layer 73 can perform a certain position limiting and blocking function for the second sealing layer 72.

[0159] Further optionally, the first sealing layer 71 includes a plurality of first sealing portions 711 each disposed within the opening structure 21, and the first sealing portions 711 and the blocking portion 90 are disposed parallel to each other with a gap therebetween in the direction in which the substrate 10 is located.

[0160] Due to the presence of the isolation structure 20, the sealing material for forming the first sealing portion 711 also falls into the opening structure 21, thereby forming a plurality of first sealing portions 711 corresponding to the opening structure 21, where the different first sealing portions 711 are spaced apart from each other.

[0161] In the embodiment of the present application, the presence of the blocking portion 90 serves to prevent overflow into the second sealing layer 72, thereby reducing the risk of the second sealing layer 72 extending away from the first region A1 of the blocking portion 90 and improving the sealing reliability of the display panel.

[0162] In some embodiments, the third sealing layer 73 is partially located on the side of the blocking portion 90 away from the substrate 10, i.e., the third sealing layer 73 extends from the first region A1 to the second region A2 and can cover at least a portion of the structure of the blocking portion 90.

[0163] In such a design, the blocking portion 90 cooperates with the third sealing layer 73 to jointly perform the role of limiting the position and blocking the second sealing layer 72, further reducing the risk of the second sealing layer 72 extending away from the first region A1, and improving the sealing reliability of the display panel.

[0164] In some embodiments, as shown in FIG. 2, the display panel further includes a scanning drive circuit D1 located between the light emitting control circuit D2 and the first region A1, and the blocking portion 90 is located on the side of the scanning drive circuit D1 away from the first region A1.

[0165] The scanning driving circuit D1 may include a multi-stage shift register cascaded to each other, and the multi-stage shift register can sequentially scan the pixel circuits of each row located in the first area A1 and sequentially output an on level to meet display needs.

[0166] The scanning drive circuit D1 and the light emission control circuit D2 are both located in the second region A2, and the scanning drive circuit D1 is located on the side closer to the first region A1 of the light emission control circuit D2. Here, based on the short distance between the scanning drive circuit D1 and the first region A1, in order to ensure the blocking effect of the blocking unit 90 against the overflow to the first sealing layer 71, in the embodiment of the present application, the blocking unit 90 is further provided on the side where the scanning drive circuit D1 is away from the first region A1, that is, the distance between the blocking unit 90 and the first region A1 is greater than the distance between the scanning drive circuit D1 and the first region A1. As a result, a certain distance size can be secured between the blocking unit 90 and the first region A1, and therefore the blocking effect of the blocking unit 90 against the overflow to the first sealing layer 71 can be improved without increasing the height size of the blocking unit 90.

[0167] In some embodiments, the display panel further includes a second insulating portion 91 disposed between the light emission control circuit D2 and at least a portion of the blocking portion 90.

[0168] The second insulating portion 91 may cover at least a portion of the structure of the light-emission control circuit D2. For example, the orthogonal projection of the second insulating portion 91 on the substrate covers the orthogonal projection of the light-emission control circuit D2 on the substrate. As a result, after the manufacture of the light-emission control circuit D2 is completed, the second insulating portion 91 serves to isolate the light-emission control circuit D2 from the air, and during the manufacturing process of subsequent metal layers, etc., the second insulating portion 91 serves to protect the light-emission control circuit D2, thereby reducing the risk of over-etching of the light-emission control circuit D2 and improving reliability.

[0169] Furthermore, the second insulating section 91 can improve the operational reliability of the light-emission control circuit D2 by insulating and separating the blocking section 90 from the light-emission control circuit D2. As can be seen from the above, the blocking section 90 may be located completely on the side of the light-emission control circuit D2 that is away from the substrate 10, or a part of the blocking section 90 may be located on the side of the light-emission control circuit D2 that is away from the substrate 10, and the other part may be located on the side of the light-emission control circuit D2 that is away from the first region A1. In view of this, the second insulating section 91 may be located completely on the side of the light-emission control circuit D2 that is away from the substrate 10, or a part of the second insulating section 91 may be located on the side of the light-emission control circuit D2 that is away from the substrate 10, and the other part may be located on the side of the light-emission control circuit D2 that is away from the first region A1.

[0170] When the blocking portion 90 is located on the side away from the substrate 10 of the light-emitting control circuit D2, the second insulating portion 91 can increase the distance between the blocking portion 90 and the substrate 10, thereby reducing the height size required for the blocking portion 90 and the corresponding material costs, and making it more practical.

[0171] In some selectable embodiments, the orthogonal projection of the blocking portion 90 on the substrate 10 is located within the orthogonal projection of the second insulating portion 91 on the substrate 10. This further improves the insulating effect of the second insulating portion 91 between the blocking portion 90 and the light-emission control circuit D2, thereby improving reliability. In addition, the presence of the second insulating portion 91 allows the distance between the blocking portion 90 and the substrate 10 to be increased, thereby reducing the height of the blocking portion 90 and reducing the material cost corresponding to the blocking portion 90.

[0172] Further optionally, the orthogonal projection of the blocking portion 90 on the substrate 10 is located within the orthogonal projection of the light emission control circuit D2 on the substrate 10.

[0173] 9, in some embodiments, the second insulating portion 91 extends from the first region A1 into the second region A2, and the orthogonal projection of the second insulating portion 91 on the substrate 10 covers the orthogonal projection of the light emission control circuit D2 on the substrate 10. That is, the second insulating portion 91 is located in a partial structure in the first region A1, and the second insulating portion 91 is integrally connected to a partial structure located in the second region A2.

[0174] In the practice of the present application, the second insulating portion 91 extends from the first region A1 into the second region A2, so that the second insulating portion 91 can not only provide insulation between different conductive structures in the first region A1, but also provide a cover protection for the light-emitting control circuit D2 in the second region A2, thereby improving the reliability of the display panel. Optionally, the second insulating portion 91 can also be a planarizing layer for other purposes, which can provide a planarized surface, thereby reducing the difficulty of subsequent manufacturing of the display panel and improving the manufacturing precision of the display panel, and thus having higher practicality.

[0175] In some embodiments, the display panel further includes a first signal line 60 located in the second region A2 and a first electrode 41 located on the side of the light-emitting structure 31 away from the substrate, and the first signal line 60 is electrically connected to the first electrode 41 via the isolation structure 20.

[0176] In the embodiment of the present application, the first signal line 60 is not directly connected to the first electrodes 41, but transmits a power signal to each of the first electrodes 41 through the isolation structure 20. Specifically, the isolation structure 20 itself is provided corresponding to each of the first electrodes 41, and signal transmission between the two can be realized. Therefore, the first signal line 60 does not need to be extended to the position of each of the first electrodes 41, that is, the first signal line 60 does not need to be provided so as to surround each of the first electrodes 41, but only needs to be provided on one side of the isolation structure 20 along the first direction X and electrically connected to the isolation structure 20. In this way, the power signal located in the first signal line 60 can be transmitted to each of the first electrodes 41 through the isolation structure 20, thereby satisfying the demand for signal transmission. In addition, since the first signal line 60 is located on one side of the isolation structure 20 along the first direction X and is not a ring structure, it contributes to reducing the frame size of the display panel and improves the display effect.

[0177] Furthermore, in some alternative embodiments, the first signal line 60 is located on one side of the isolation structure 20 along a first direction X, which is parallel to the plane in which the substrate 10 is located.

[0178] In addition, the specific wiring form of the first signal lines 60 is not limited to the embodiment of the present application. According to the actual situation, the first signal lines 60 may be completely located on one side of the isolation structure 20 along the first direction X, or a small number of the first signal lines 60 may be located on the other side of the isolation structure 20 along a different direction, as long as most of the first signal lines 60 are located on the same side of the isolation structure 20.

[0179] In some embodiments, referring to FIGS. 2, 3 and 7, the orthogonal projection of the blocking portion 90 on the substrate 10 and the orthogonal projection of the first signal line 60 on the substrate 10 are misaligned.

[0180] The blocking portion 90 is located in the second region A2, and is usually located at the edge position of the display panel. As can be seen from the above, the second sealing layer 72 contains an organic material, and the organic material contained in the second sealing layer 72 usually has a certain fluidity. In order to reduce the risk of the organic material in the second sealing layer 72 overflowing, the blocking portion 90 is usually provided at the edge position of the display panel. The presence of the blocking portion 90 can reduce the risk of overflow and improve the reliability of the display panel.

[0181] Furthermore, the first signal line 60 is located on one side of the isolation structure 20 only along the first direction X, and is not provided to surround the periphery of the isolation structure 20, so that the first signal line 60 does not exist in a partial position in the second region A2. Based on this, the orthogonal projection of the blocking portion 90 on the substrate 10 and the orthogonal projection of the first signal line 60 on the substrate 10 are distributed in a misaligned position, that is, the first signal line 60 does not affect the layout design of the blocking portion 90, which helps to reduce the risk of physical interference between them.

[0182] The specific arrangement of the blocking portion 90 is not limited to the embodiment of the present application. Optionally, the partial structure of the blocking portion 90 may be located on at least one side of the isolation structure 20 in the second direction Y.

[0183] In some embodiments, as shown in Figures 1 to 3, the isolation structure 20 includes a first isolation portion 22 and a second isolation portion 23 that are stacked sequentially along a direction away from the substrate 10, and the orthogonal projection of the first isolation portion 22 on the substrate 10 is located within the orthogonal projection of the second isolation portion 23 on the substrate 10.

[0184] The specific size and shape of the first isolation portion 22 and the second isolation portion 23 are not limited in the embodiments of the present application. For example, the vertical section of the isolation structure 20 may be T-shaped. This design helps prevent the luminescent material and the electrode material from extending along the sidewall of the first isolation portion 22 to the sidewall of the second isolation portion 23 during the manufacturing process of the light emitting functional layer and the first electrode layer 40, and realizes the manufacture and mutual isolation of the light emitting structures 31 and the first electrodes 41 in different opening structures 21 without the need for a precise metal mask.

[0185] The material compositions of the first isolation portion 22 and the second isolation portion 23 are not limited in the embodiments of the present application. Both the first isolation portion 22 and the second isolation portion 23 may include a conductive material, or the first isolation portion 22 may include a conductive material and the second isolation portion 23 may include an insulating material, as long as the first electrode 41 can realize signal transmission through the isolation structure 20.

[0186] Also, at least a portion of the first signal line 60 is located within the second region A2, and the first signal line 60 may be located entirely within the second region A2, or the first signal line 60 may extend partially within the first region A1. Similarly, the isolation structure 20 may be located entirely within the first region A1, or the isolation structure 20 may extend partially within the second region A2, and the embodiments of the present application are not limited thereto.

[0187] In some embodiments, the first isolation portion 22 comprises a conductive material, and the first electrode 41 is provided in electrical connection with the first isolation portion 22 .

[0188] The first signal line 60 can realize the transmission of a power signal to the first electrode 41 via the first isolation portion 22, where the first electrode 41 may be in direct contact with the first isolation portion 22, or the first electrode 41 may be electrically connected to the first isolation portion 22 via another conductive structure, and the embodiments of the present application are not limited thereto.

[0189] In the embodiment of the present application, by disposing a conductive material in the first isolation portion 22, the first signal line 60 can realize the transmission of a power signal to the first electrode 41 through the first isolation portion 22, thereby satisfying the demand for signal transmission. Furthermore, by providing an extension path for 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 the first signal line 60 only needs to be provided on one side of the isolation structure 20 along the first direction X, without the need to provide the first signal line 60 so as to surround the first area A1, thereby reducing the frame size of the display panel.

[0190] The positional relationship between the first signal line 60 and the first isolation portion 22 is not limited in this embodiment of the present application. In some examples, at least a portion of the first signal line 60 may contact the first isolation portion 22, i.e., the power signal in at least a portion of the first signal line 60 may be directly transmitted into the first isolation portion 22. Furthermore, when the isolation structure 20 further includes another conductive structure electrically connected to the first isolation portion 22, the first signal line 60 may contact the other conductive structure.

[0191] In some embodiments, referring to FIG. 4 , the isolation structure 20 further includes a third isolation portion 24 located on the side of the first isolation portion 22 facing the substrate 10, the third isolation portion 24 including a conductive material and being electrically connected to the first isolation portion 22.

[0192] The isolation structure 20 includes at least a first isolation portion 22, a second isolation portion 23, and a third isolation portion 24, and the size and shape of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24 are not limited in the embodiment of the present application. Exemplarily, the orthogonal projection of the first isolation portion 22 on the substrate 10 is located within the orthogonal projection of the third isolation portion 24 on the substrate 10, that is, the vertical cross-sectional shapes of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24 are U-shaped.

[0193] Similar to the first isolation portion 22, the third isolation portion 24 also includes a conductive material, and the first electrode 41 can be in direct contact with the third isolation portion 24 to realize an electrical connection with the first isolation portion 22 through the third isolation portion 24. Optionally, the first electrode 41 is overlappingly connected to the third isolation portion 24. Furthermore, the first electrode 41 may 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 41 and the isolation structure 20.

For example, there is one light-emitting structure 31 in one aperture structure 21, or there are a plurality of light-emitting structures 31 of the same emission color in one aperture structure 21.

[0195] The light emission control circuit D2 is located within the second region A2, the blocking section 90 is provided within the second region A2, and at least a portion of the blocking section 90 is provided adjacent to the light emission control circuit D2.

[0196] In the embodiment of the present application, the isolation structure 20 is surrounded to form a plurality of opening structures 21, and at least some of the opening structures 21 can accommodate a film layer structure having fluidity, so that the presence of the isolation structure 20 can reduce the thickness size of some of the film layers in the second region A2. Based on this, in the embodiment of the present application, the blocking portion 90 can be appropriately moved in a direction approaching the first region A1 without excessively increasing the height of the blocking portion 90, and at least a part of it can be positioned on the side away from the substrate 10 of the gate electrode driving circuit, thereby solving the problem that the distance between the blocking portion 90 and the first region A1 is too large, resulting in an excessively large frame size of the display panel, i.e., helping to reduce the frame size of the display panel and improve the display effect.

[0197] In a fourth aspect, as shown in Figures 1 to 3, an embodiment of the present application provides a display panel, the display panel has a first area A1 and a second area A2, the first area A1 includes a display area, and the second area A2 includes a lower frame area, the display panel includes a substrate 10, an isolation structure 20, a light-emitting functional layer, and a first signal line 60, the isolation structure 20 is provided on one side of the substrate 10 and is located at least in the first area A1, the isolation structure 20 forms a plurality of aperture structures 21 spaced apart from each other, the isolation structure 20 includes a conductive material, the light-emitting functional layer is provided on one side of the substrate 10 and is located in the first area A1, the light-emitting functional layer includes a plurality of light-emitting structures 31 respectively provided in the plurality of aperture structures 21, and there is at least one light-emitting structure 31 in one aperture structure 21. For example, there is one light-emitting structure 31 in one aperture structure 21, or there are a plurality of light-emitting structures 31 of the same light-emitting color in one aperture structure 21.

[0198] The first signal line 60 is located on one side of the isolation structure 20 along a first direction X, and the first signal line 60 is connected to the conductive material of the isolation structure 20, and the first direction X is a direction from the display area to the lower frame area.

[0199] In the embodiment of the present application, the first area A1 includes a display area, and the second area A2 includes a lower frame area, in which a driving chip may be provided, and the first signal line 60 is located on one side of the first area A1 along the first direction X without surrounding the first area A1, and transmits signals to different positions in the first area A1 through the isolation structure 20, thereby satisfying the need for signal transmission. In addition, since the first signal line 60 is located on one side of the isolation structure 20 along the first direction X and is not a ring structure, it contributes to reducing the frame size of the display panel and improves the display effect.
