[0019] The following describes in detail the features and exemplary examples of each aspect of the present application. In the following detailed description, many specific details are described in order to provide a comprehensive understanding of the present application. However, it is apparent to those skilled in the art that the present application may be practiced without the need for some of these specific details. The following description of the embodiments is merely provided to illustrate examples of the present application and to provide a better understanding of the present application.

[0020] It should be noted that, in this specification, relational terms such as first and second are merely intended to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that such an actual relationship or order exists between these entities or operations. Also, the terms "comprise," "have," "comprise," or any other variation thereof are intended to cover a non-exclusive inclusion, and a process, method, article, or device that includes a set of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article, or device. Absent more limitations, an element limited by the phrase "comprises" does not exclude the presence of other identical elements in the process, method, article, or equipment that includes the element.

[0021] The inventors have found that the reason why the display device is prone to have a mutual interference problem between signals in the frame is that in the conventional display panel, the touch wiring of the touch layer is prone to interference between the non-display area and the signal line in the substrate, since there is no metal layer as a shield barrier between the non-display area and the signal line in the substrate. Based on the research into the above problem, the inventors provide a display panel and a manufacturing method thereof, and a display device for reducing the signal interference problem in the non-display area.

[0022] For a better understanding of the present application, a display panel, a manufacturing method thereof, and a display device according to embodiments of the present application will be described in detail below with reference to FIGS.

[0023] 1 and 2, an embodiment of the present application provides a display panel 1 including a display area AA and a non-display area NA surrounding at least a part of the display area AA. The display panel 1 includes a substrate 11, a light-emitting unit 13, a shield structure, and a conductive layer 15.

[0024] The light-emitting units 13 are formed on one side of the substrate 11 and are located within the display area AA, and the conductive layer 15 is formed on the side of the light-emitting units 13 facing away from the substrate 11. The shielding structure is provided between the conductive layer 15 and the substrate 11 and is at least partially located within the non-display area NA, such that the orthogonal projection of the shielding structure on the substrate 11 overlaps with the orthogonal projection of the conductive layer 15 on the substrate 11.

[0025] The display panel 1 of the present application includes a display area AA and a non-display area NA. The display area AA is an area for realizing the display function in the display panel 1. The non-display area NA is provided surrounding the periphery of the display area AA. The non-display area NA is used for arranging structures such as a driving chip and a driving circuit.

[0026] The display panel 1 includes a substrate 11, and film layers or device structures such as the light-emitting units 13, the shielding structure, and the conductive layer 15 are formed on the same side of the substrate 11. Here, the substrate 11 may include a plurality of film layer structures stacked together, and the specific configuration manner of the film layers in the substrate 11 is not limited by the embodiment of the present application. For example, the substrate 11 may include a plurality of conductor layers and semiconductor layers, and an insulating layer located between adjacent conductor layers and semiconductor layers, and a conductor structure is provided in the conductor layer, and an active structure is provided in the semiconductor layer. Furthermore, the substrate includes a circuit structure, and the circuit structure may include a pixel circuit in the display area, a scanning circuit in the non-display area, or other types of circuits, and the embodiment of the present application is not limited by the embodiment of the present application.

[0027] A thin film transistor may be provided within the substrate 11 to form a pixel circuit for driving the light emission of the light emitting unit 13, and the thin film transistor includes a conductor structure located within a portion of the conductor layer and an active structure located within the semiconductor layer.

[0028] In the related art, some structures in the conductive layer 15 and some conductor structures in the substrate 11, such as the signal lines 111, are provided facing each other in the non-display area NA, and therefore interference between them is likely to occur. In view of this, an embodiment of the present application adds a shielding structure in the display panel 1, which is provided between the conductive layer 15 and the substrate 11 and is at least partially located in the non-display area NA, and the presence of the shielding structure provides a signal shielding effect for the part of the structure of the conductive layer 15 located in the non-display area NA and the signal lines 111 in the substrate 11, thereby reducing the risk of signal interference, thereby protecting the conductor structures and the conductive layer 15 in the substrate 11 and improving the yield and usage reliability of the display panel 1.

[0029] It should be noted that the embodiments of the present application do not limit the specific type of the conductor layer 15. Alternatively, the structure in the conductor layer 15 may be used to transmit touch signals, or the structure in the conductor layer 15 may be used to transmit other signals, as long as the conductor layer 15 is located on the side of the light-emitting unit 13 away from the substrate 11.

[0030] In some embodiments, the shielding structure includes an isolation structure 12 formed on one side of a substrate, the isolation structure 12 including a first portion 121 located in a display area AA and a second portion 122 located in a non-display area NA, the first portion 121 surroundingly forms a first opening 1211, and the light-emitting unit 13 is located in the first opening 1211. An orthogonal projection of the second portion 122 on the substrate 11 overlaps with an orthogonal projection of the conductive layer 15 on the substrate 11.

[0031] The isolation structure 12 is formed on one side of the substrate 11 and includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NA, the first portion 121 is surrounded to form a first opening 1211, and the second portion 122 is surrounded to form a second opening 1221, the first opening 1211 is for accommodating the light-emitting unit 13, and the first opening 1211 can prevent the isolation structure 12 from blocking the light emission of the light-emitting unit 13.

[0032] In the embodiment of the present application, the second portion 122 of the isolation structure 12 is located in the non-display area NA, and the orthogonal projection of the second portion 122 on the substrate 11 is arranged to overlap with the orthogonal projection of the conductive layer 15 on the substrate 11. In such a design, the presence of the second portion 122 realizes mutual shielding between the portion of the conductive layer 15 located in the non-display area NA and the signal line 111 located in the non-display area NA of the substrate 11, thereby reducing mutual interference between the signals of the portion of the conductive layer 15 located in the non-display area NA and the signals in the signal line 111, and improving the usage reliability of the display panel 1.

[0033] Further optionally, in the non-display area NA, the orthogonal projection of the second portion 122 on the substrate 11 completely covers the orthogonal projection of the conductive layer 15 on the substrate 11 .

[0034] In the embodiments of the present application, the dimensions and shape of second portion 122 depend on the structure of the portion of conductor layer 15 located in non-display area NA, and by adjusting the dimensions and shape of second portion 122, the orthogonal projection on substrate 11 is made to completely cover the orthogonal projection of conductive layer 15 on substrate 11, thereby improving the shielding effect of second portion 122 between the portion of conductive layer 15 located in non-display area NA and signal line 111 located within the non-display area NA of substrate 11.

[0035] Alternatively, the first and second parts of the isolation structure may not be completely the same, but may be made of at least a part of the film layer material of the first and second parts, and may be made of the same layer, for example, the isolation structure may include a first layer and a second layer stacked on each other, and only the first layer or the second layer of the first and second parts may be made the same. In this way, the manufacturing process is simplified, and the manufacturing of the shielding structure can be completed using conventional processes.

[0036] Of course, the first portion and the second portion may be provided as a completely identical film layer structure, and the present application does not specifically limit this.

[0037] The second part may be a one-sided structure in the non-display area and is arranged to surround the display area, in this way forming a shielding structure all around the display area to avoid mutual interference between the conductive layer and the circuit structure.

[0038] The second portion having a one-sided structure means that at least a part of the film layer structure does not have a second opening in the non-display area.

[0039] In some embodiments, the light-emitting unit 13 may include a first electrode 131, a light-emitting functional layer 132 and a second electrode 133 stacked along a direction away from the substrate 11, and the shielding structure includes a shielding layer 14, which is manufactured in the same layer as the second electrode 133.

[0040] The shield layer 14 and the second electrode 133 are manufactured in the same layer, i.e., the shield layer 14 and the second electrode 133 are located in the same film layer, and further, both are manufactured together in the same process so that the same conductive material is contained within both.

[0041] In another embodiment, the shield layer 14 is manufactured in the same layer as the first electrode 131, i.e., the shield layer 14 and the first electrode 131 are located in the same film layer, and further both are manufactured together in the same process so that they both contain the same conductive material.

[0042] The second electrode 133 is located in the display area AA, and works together with the first electrode 131 to drive the light emitting functional layer 132 to achieve the light emitting function, thereby meeting the display demand of the display panel 1. The shield layer 14 is manufactured in the same layer as the second electrode 133, and is provided in the non-display area NA, so that the presence of the shield layer 14 realizes mutual shielding between the portion of the conductive layer 15 located in the non-display area NA and the signal line 111 located in the non-display area NA of the substrate 11, thereby reducing mutual interference between the signals of the portion of the conductive layer 15 located in the non-display area NA and the signals in some of the conductor structures in the substrate 11, and improving the use reliability of the display panel 1.

[0043] In some alternative embodiments, the orthogonal projection of the shield layer 14 on the substrate 11 is provided to overlap with the orthogonal projection of the conductive layer 15 on the substrate 11. Further alternatively, in the non-display area NA, the orthogonal projection of the shield layer 14 on the substrate 11 completely covers the orthogonal projection of the conductive layer 15 on the substrate 11.

[0044] In the embodiments of the present application, the dimensions and shape of shielding layer 14 depend on the structure of the portion of conductive layer 15 located in non-display area NA, and by adjusting the dimensions and shape of shielding layer 14, the orthogonal projection on substrate 11 is made to completely cover the orthogonal projection of conductive layer 15 on substrate 11, thereby improving the shielding effect of shielding layer 14 between the portion of conductive layer 15 located in non-display area NA and signal line 111 located within the non-display area NA of substrate 11.

[0045] In some embodiments, the shielding structure includes an isolation structure 12 and a shielding layer 14 formed on one side of the substrate 11, the isolation structure 12 includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NA, the first portion 121 is surrounded to form a first opening 1211, and the second portion 122 is surrounded to form a second opening 1221. The light-emitting unit 13 is located in the first opening 1211, the shielding layer 14 includes a first sub-portion 141 located in the second opening 1221, and the first sub-portion 141 is electrically connected to the second opening 1221.

[0046] The isolation structure 12 includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NA, and the first portion 121 and the second portion 122 respectively surround each other to form a first opening 1211 and a second opening 1221. At least one light-emitting unit 13 may be formed in each first opening 1211, and a second electrode 133 of the light-emitting unit 13 is electrically connected to the first portion 121 to realize synchronous power supply to the second electrode 133.

[0047] At least a portion of shield layer 14 is formed in second opening 1221 and is electrically connected to second portion 122. This allows second portion 122 in non-display area NA and shield layer 14 to form a continuous film layer, thereby achieving mutual shielding between the portion of conductive layer 15 located in non-display area NA and signal line 111 in non-display area NA of substrate 11, reducing mutual interference between signals of the portion of conductive layer 15 located in non-display area NA and signals in signal line 111 in substrate 11, and improving the yield of display panel 1.

[0048] At the same time, the second portion 122 in the non-display area NA surrounds and forms a second opening 1221, and at least a part of the shield layer 14 is located in the second opening 1221, thereby realizing the shield layer 14 and the isolation structure 12 being alternately arranged along a direction parallel to the substrate 11, thereby reducing the problem that a large area of ​​metal is easily peeled off after coming into contact with the lower film layer, and also preventing static electricity to protect the signal line 111 in the substrate 11, thereby reducing the problem of the signal line 111 in the substrate 11 turning black, breaking, disconnecting, etc. due to static electricity, which causes problems such as circuit disconnection and short circuit.

[0049] Furthermore, in the isolation structure 12, the first portion 121 and the second portion 122 may be connected to each other so as to realize synchronous power supply between the first portion 121 and the second portion 122. By supplying DC power into the isolation structure 12, it is possible to realize synchronous power supply within the second portion 122 and the shielding layer 14, and synchronous power supply between the first portion 121 and the second electrode 133, and by passing DC power through the second portion 122 and the shielding layer 14, it is possible to realize a good shielding effect.

[0050] Specifically, the first portion 121 and the second portion 122 can be patterned simultaneously to form a network structure, or the first portion 121 and the second portion 122 can be a unitary structure.

[0051] Specifically, the orthogonal projection of the first sub-portion 141 on the second opening 1221 can cover the second opening 1221. Thus, the positions between the second openings 1221 are shielded by the second portion 122, and the positions within the second openings 1221 are shielded by the first sub-portion 141, achieving a sealed shielding effect.

[0052] In addition, in some embodiments, in addition to the first sub-portion 141, the shielding layer 14 further includes a second sub-portion 142 located on a side of the second portion 122 facing away from the substrate 11. That is, during the manufacturing process of the shielding layer 14, some material falls into the second opening 1221 to form the first sub-portion 141, and some material falls on the side of the second portion 122 facing away from the substrate 11 to form the second sub-portion 142.

[0053] In one feasible embodiment, as shown in FIG. 4, the light-emitting unit 13 includes a first electrode 131, a light-emitting functional layer 132 and a second electrode 133 stacked along a direction away from the substrate 11, and the shielding layer 14 is manufactured in the same layer as the second electrode 133.

[0054] In the above embodiment, the shield layer 14 can be manufactured at the same time as the second electrode 133 is manufactured. That is, the second electrode 133 and the shield layer 14 are manufactured and formed of the same material and in the same process, so that the manufacturing process of the display panel 1 can be simplified and the manufacturing cost can be saved without increasing the manufacturing process of the display panel 1. In the manufacturing process of the shield layer 14, a first sub-portion 141 located in the second opening 1221 and a second sub-portion 142 located on the side of the second branch 1322 away from the second portion 122 can be formed, and the first sub-portion 141 is electrically connected to the second portion 122 and covers the second opening 1221, thereby forming a single layer sealed by the second portion 122 and the first sub-portion 141 to improve the shielding effect.

[0055] In one possible embodiment, as shown in FIG. 2 , the light emitting layer 1320 further includes an emissive material layer 1320, which is disposed in the same layer as at least a portion of the light emitting functional layer 132, and which includes a first branch 1321 located within the second opening 1221 and a second branch 1322 located on the side of the second portion 122 away from the substrate 11.

[0056] In the above embodiment, the light emitting material layer 1320 is provided in the same layer as the light emitting functional layer 132 and is manufactured in the same manufacturing process. The light emitting material layer 1320 includes a first branch 1321 located in the second opening 1221 and a second branch 1322 located on the side of the second portion 122 away from the substrate 11.

[0057] 2 and 4, in one possible embodiment, the non-display area NA further includes a leveling area NA1 located on a side of the second portion 122 away from the display area AA, and the display panel 1 further includes an encapsulating layer 16 located on a side of the shielding layer 14 and the light-emitting unit 13 away from the substrate 11, and between the substrate 11 and the conductive layer 15. Along a direction perpendicular to the plane in which the substrate 11 is located, the thickness of the encapsulating layer 16 located in the leveling area NA1 is smaller than the thickness of the portion located in the display area AA, and smaller than the thickness of the portion located between the leveling area NA1 and the display area AA.

[0058] In the above embodiment, the display panel 1 further includes a sealing layer 16, which is located between the light-emitting unit 13 and the conductive layer 15 and between the shield layer 14 and the conductive layer 15. The sealing layer 16 may include a first sealing layer 161, a second sealing layer 162 and a third sealing layer 163 stacked along a direction away from the substrate 11. The material of the first sealing layer 161 and the third sealing layer 163 may be an inorganic material, which has a strong ability to block moisture and oxygen, and the material of the second sealing layer 162 may be an organic material, which has strong fluidity.

[0059] 4, the non-display area NA further includes a leveling area NA1 in a direction away from the display area AA for achieving leveling of the second sealing layer 162. The non-display area NA may further include a barrier area NA2 located on the side of the leveling area NA1 away from the display area AA, and the barrier area NA2 includes a dam 18 for achieving a barrier against the second sealing layer 162.

[0060] Specifically, the leveling area NA1 has a dimension D along the direction from the display area AA to the non-display area NA that is greater than 50 μm, thereby providing sufficient space for leveling of the second sealing layer 162 and improving the flatness of the side of the second sealing layer 162 away from the substrate 11.

[0061] In the above embodiment, the encapsulation layer 16 can be gradually thinned in thickness from the display area AA to the leveling area NA1. Here, the thickness refers to a dimension perpendicular to the plane on which the substrate 11 is located, that is, along the thickness direction of the substrate 11. The portion of the encapsulation layer 16 located above the second portion 122 also gradually becomes thinner from the display area AA to the leveling area NA1, and in particular, the encapsulation layer 16 located above the second portion 122 located at a position away from the display area AA becomes thinner more significantly. At this time, by forming the second branch 1322 of the light emitting material layer 1320 and the second sub-portion 142 of the shield layer 14 on the side of the second portion 122 away from the substrate 11, the first encapsulation layer 161 can be continuously provided on the side of the second portion 122 away from the substrate, and the encapsulation layer 16 can contact the side away from the second opening 1221 of the isolation structure 12. This covers the surface of second portion 122 facing away from substrate 11, thereby achieving sealing, reducing the probability of second portion 122 being exposed after a sealing failure, preventing the problem of shielding failure occurring in second portion 122, and improving the reliability of the shielding effect of second portion 122.

[0062] In one possible embodiment, the sealing layer 16 contacts the side of the isolation structure 12 facing the second opening 1221, so that the sealing layer 16 covers the first sub-portion 141 and is overlapped and connected to the isolation structure 12 to form a good sealing effect.

[0063] In one possible embodiment, the shielding layer 14 includes a first sub-portion 141 located within the second opening 1221 and a second sub-portion 142 located on the side of the second portion 122 facing away from the substrate 11, and the sealing layer 16 contacts the side of the second sub-portion 142 facing away from the substrate 11, thereby preventing the sealing layer 16 from floating in the air and improving the probability of moisture and oxygen entering between the sealing layer 16 and the lower film layer from the floating position, thereby improving the sealing yield, further improving the shielding effect, and reducing the probability of shielding failure after the first sub-portion 141 is eroded by moisture and oxygen.

[0064] In one possible embodiment, the conductive layer 15 includes a touch layer, which includes a touch wiring 151 located in the non-display area NA, and the orthogonal projection of the touch wiring 151 on the substrate 11 is located within the orthogonal projection of the shielding layer 14 on the substrate 11 and / or is located within the orthogonal projection of the isolation structure 12 on the substrate 11.

[0065] In the above embodiment, the conductive layer 15 may include a touch layer to realize a touch function, or may include other film layers, which are not particularly limited in the present application. The touch layer includes a touch wiring 151 located in the non-display area NA, the shield layer 14 contacts the second part 122 to form a continuous shielding surface, and the orthogonal projection of the touch wiring 151 on the substrate 11 is located within the orthogonal projection of the shield layer 14 on the substrate 11 and / or is located within the orthogonal projection of the isolation structure 12 on the substrate 11, thereby realizing shielding between the touch wiring 151 and the film layer having conductive performance in the substrate 11.

[0066] Specifically, as shown in FIG. 3, the touch layer further includes a touch electrode 152 and a connecting line 153 located in the display area AA, the touch electrode 152 may include a first touch electrode 1521 and a second touch electrode 1522, the connecting line 153 may include a first connecting line 1531 and a second connecting line 1532, and the touch layer may include a first conductive layer and a second conductive layer stacked along a direction away from the substrate 11, and the first conductive layer and the second conductive layer are insulated from each other. The first conductive layer includes a first connecting line 1531, and the second conductive layer includes a touch electrode 152 and a second connecting line 1532, the first touch electrodes 1521 are arranged in a matrix, and first touch electrodes 1521 that are at least partially adjacent along the column direction are electrically connected by the first connecting line 1531, the second touch electrodes 1522 are arranged in a matrix, and second touch electrodes 1522 that are at least partially adjacent along the row direction are electrically connected by the second connecting line 1532, and the connecting line 153 and / or the touch electrode 152 are directly connected to the touch wiring 151.

[0067] In one possible embodiment, the substrate 11 includes a metal layer, the metal layer includes a metal line located in the non-display area NA, the metal line includes a signal line 111, which is different from the signal in the touch line 151. The orthogonal projection of the touch line 151 on the metal layer at least partially overlaps with the metal line. The overlapping area is more likely to cause interference, and the shielding layer 14 and the isolation structure 12 can realize shielding for the touch line 151 and the signal in the metal line, reduce the interference, and improve the performance of the display panel 1.

[0068] In one possible embodiment, as shown in FIG. 5, the non-display area NA includes at least one second opening 1221, which is arranged to surround the display area AA.

[0069] Specifically, the non-display area NA includes only one second opening 1221, which is arranged to surround the display area AA, or the non-display area NA includes a plurality of second openings 1221, each of which is arranged to surround the display area AA, and the plurality of second openings 1221 are arranged so as to be nested in sequence (not shown).

[0070] By providing the second opening 1221 so as to surround the display area AA, the area of ​​the second opening 1221 can be increased, thereby ensuring the flatness of the film layer below the touch wiring 151 and reducing the risk of the touch wiring 151 breaking.

[0071] In one possible embodiment, as shown in Figures 5 and 6, the touch wiring 151 includes a wiring section 1510 that extends to surround a portion of the display area AA, and the orthogonal projection of the wiring section 1510 on the substrate 11 is located within the orthogonal projection of the second opening 1221 on the substrate 11.

[0072] Specifically, the edge of the display area AA may be rectangular, and the wiring section 1510 may include a portion extending along the row direction in the arrangement direction of the touch electrodes 152 and a portion extending along the column direction, with the row direction and column direction being parallel to two sides of the rectangle, respectively.

[0073] The wiring section 1510 extends to surround a part of the display area AA, that is, the extension direction of the wiring section 1510 and the second opening 1221 are the same, so that the orthogonal projection of the wiring section 1510 on the substrate 11 is located within the orthogonal projection of the second opening 1221 on the substrate 11, and the first sub-portion 141 of the shield layer 14 is provided within the second opening 1221, so that the first sub-portion 141 can shield the wiring section 1510 and the signal line 111 in the substrate 11. At the same time, the wiring section 1510 does not pass through the edge of the second opening 1221, so that the flatness of the film layer below the wiring section 1510 is improved, the risk of short circuit or disconnection of the touch wiring 151 is reduced, and the reliability and stability of the touch wiring 151 is improved. At the same time, the film layer below the wiring section 1510 is made the same, which improves the difference between different wiring sections 1510 and contributes to improving the transmission quality of the touch signal.

[0074] Specifically, the orthogonal projection of the wiring section 1510 on the substrate 11 is located within the orthogonal projection of the shielding layer 14 on the substrate 11. Specifically, the orthogonal projection of the wiring section 1510 on the substrate 11 is located within the orthogonal projection of the first sub-portion 141 on the substrate 11. As a result, the wiring section 1510 does not pass above the edge of the isolation structure 12, but passes only above the first sub-portion 141, thereby improving the flatness of the film layer below the wiring section 1510 and enabling the first sub-portion 141 to achieve a good shielding effect.

[0075] In one possible embodiment, as shown in FIG. 2 , the touch wiring 151 includes a wiring section 1510 that extends to surround a portion of the display area AA, and the orthogonal projection of the portion of the wiring section 1510 on the substrate 11 is located within the orthogonal projection of the second opening 1221 on the substrate 11, and the orthogonal projection of the portion of the wiring section 1510 on the substrate 11 is located within the orthogonal projection of the second portion 122 on the substrate 11, and the edges of the orthogonal projection of the second portion 122 on the substrate 11 do not overlap with the orthogonal projection of the wiring section 1510 on the substrate 11.

[0076] In the above embodiment, the orthogonal projection of some of the wiring sections 1510 on the substrate 11 is located within the orthogonal projection of the second opening 1221 on the substrate 11, and the orthogonal projection of some of the wiring sections 1510 on the substrate 11 is located within the orthogonal projection of the second portion 122 on the substrate 11. That is, some of the wiring sections 1510 are located above the second opening 1221, and some of the wiring sections 1510 are located above the second portion 122, and both can ensure the flatness of the film layer below the wiring sections 1510, and it is only necessary that the wiring sections 1510 are not located above the edge of the second portion 122, i.e., the edge of the second portion 122, which is a transition region between the second portion 122 and the second opening 1221, has a step, and is disadvantageous in ensuring the flatness.

[0077] In one possible embodiment, as shown in Figures 7 and 8, the non-display area NA includes a plurality of second openings 1221, and the plurality of second openings 1221 are arranged along the circumferential direction of the display area AA. The touch wiring 151 includes a first segment extending along a first direction, and the orthogonal projection of some of the plurality of second openings 1221 on the substrate 11 is rectangular, and the dimensions of some of the second openings 1221 along the first direction are the same. This ensures that the widths of the second portions 122 between the second openings 1221 through which each first segment passes are relatively consistent, ensures the consistency of the film layer below the touch wiring 151, reduces the difference between different touch wirings 151, and contributes to ensuring touch quality.

[0078] In the above embodiment, the edge of the display area AA may be a rectangle including a long side and a short side, and the first direction may be parallel to the long side direction.

[0079] In the above embodiment, the plurality of second openings 1221 are uniformly arranged in the non-display area NA, thereby reducing the difference between each of the first segments.

[0080] In the above embodiment, the area of ​​the orthogonal projection of at least a portion of the second openings 1221 on the substrate 11 is larger than the area of ​​the orthogonal projection of the first openings 1211 on the substrate 11. By setting the area of ​​the second openings 1221 to be larger, the flatness of the film layer below the touch wiring 151 can be improved, and the yield of the touch wiring 151 can be improved.

[0081] In addition, the first openings 1211 are for accommodating the light emitting units 13, and for the light emitting units 13 of different colors, the orthogonal projection areas on the substrate 11 of the first openings 1211 corresponding to the light emitting units 13 of different colors may be the same or different. The orthogonal projection areas on the substrate 11 of at least some of the second openings 1221 need to be larger than the orthogonal projection area on the substrate 11 of the largest first opening 1211, thereby improving the flatness of the film layer below the touch wiring 151.

[0082] In the above embodiment, the extension direction of a portion of the second portion 122 located between two adjacent second openings 1221 along the circumferential direction of the display area AA intersects with the extension direction of the touch wiring 151, and the orthogonal projection on the substrate 11 of a portion of the second portion 122 located between two adjacent second openings 1221 along the circumferential direction of the display area AA is a first projection, and the first projection partially overlaps with the orthogonal projection on the substrate 11 of the touch wiring 151. That is, one touch wiring 151 passes above multiple second openings 1221 along its length direction.

[0083] In one possible embodiment, as shown in Figures 2 and 4, the isolation structure 12 includes a first isolation portion 123 and a second isolation portion 124, the second isolation portion 124 is located on the side of the first isolation portion 123 away from the substrate 11, and the orthogonal projection of the second isolation portion 124 on the substrate 11 covers the orthogonal projection of the first isolation portion 123 on the substrate 11.

[0084] In the above embodiment, the first portion 121 and the second portion 122 of the isolating portion may both include a first isolating portion 123 and a second isolating portion 124 .

[0085] In the above embodiment, a step portion is formed between the first isolation portion 123 and the second isolation portion 124, which isolates the light-emitting functional layer 132 and the second electrode 133 in the display area AA, making the light-emitting functional layers 132 in adjacent light-emitting units 13 independent of each other, and making the second electrodes 133 in adjacent light-emitting units 13 independent of each other. Also, instead of insulating the light-emitting material layer 1320 and the shield layer 14 in the display area NA, the light-emitting material layer 1320 manufactured in the same layer as the light-emitting functional layer 132 can be formed at the same time as forming the light-emitting functional layer 132.

[0086] In the above embodiment, since the second electrodes 133 are independent of each other, it is difficult to supply power to each second electrode 133. Therefore, by electrically connecting at least some of the second electrodes 133 through the first part 121 of the isolation structure 12 and then supplying power synchronously, synchronous power supply to each second electrode 133 is realized, and the number of power supply lines and the manufacturing process are simplified. At the same time, the material of the second electrode 133 is often selected as magnesium silver alloy, and the material of the isolation structure 12 includes aluminum, which has a lower electrical resistance than magnesium silver alloy, so that the electrical connection method of the isolation structure 12 and the second electrode 133 has a lower electrical resistance than the conventional one-sided second electrode 133, and the power consumption of the display panel 1 can be reduced. Therefore, the difference caused by attenuation (IR-DROP) in the signal transmission process between the proximal driving end and the principle driving end due to the high electrical resistance can be reduced, which contributes to improving the uniformity of the panel display.

[0087] In the above embodiment, after being blocked by the second portion 122, the shielding layer 14 forms a first sub-portion 141 located within the second opening 1221 and a second sub-portion 142 located on the side of the second branch 1322 away from the second portion 122, and the electrical connection between the second portion 122 and the second sub-portion 142 can realize the electrical connection of multiple second sub-portions 142, thereby facilitating synchronous power supply between the second portion 122 and the second sub-portion 142, forming a sealed membrane layer, and realizing the shielding function.

[0088] In one possible embodiment, as shown in Figures 2 and 4, the pixel definition layer 17 is further included, and a portion of the pixel definition layer 17 located in the display area AA is formed on the side of the first electrode 131 away from the substrate 11, and a portion of the pixel definition layer 17 located in the non-display area NA is in contact with the substrate 11, and the pixel definition layer 17 includes a pixel limiting portion 171 and a plurality of pixel openings 172 located in the display area AA, and the pixel openings 172 are arranged opposite the first openings 1211.

[0089] In the above embodiment, the portion of the pixel definition layer 17 located in the display area AA covers the edges of the first electrodes 131, thereby protecting the first electrodes 131, realizing mutual insulation between adjacent first electrodes 131, and reducing interference between adjacent first electrodes 131. The portion of the pixel definition layer 17 located in the display area AA includes at least a first pixel opening 172, a second pixel opening 172, and a third pixel opening 172. Specifically, when the display panel 1 includes three color light emitting units 13, the first pixel opening 172 is used to form a red light emitting unit 13, the second pixel opening 172 is used to form a green light emitting unit 13, and the third pixel opening 172 is used to form a blue light emitting unit 13. When the display panel 1 further includes a white light emitting unit 13, the pixel definition layer 17 may further include a fourth pixel opening 172 for forming the white light emitting unit 13.

[0090] The portion of the pixel definition layer 17 located in the non-display area NA contacts the substrate 11, providing a flat surface for subsequent film layers, improving the reliability of the touch wiring 151, and reducing the occurrence of defects such as circuit breaks and short circuits.

[0091] When the display panel 1 includes the isolation structure 12, the light emitting units 13 of each color are first manufactured in one layer and then patterned, so that the use of a mask can be omitted and the cost can be reduced. The light emitting units 13 of different colors are manufactured in different orders, and in the manufacturing process of the light emitting units 13 manufactured later, they can be isolated by the isolation structure 12, so that the yield of the patterning process can be improved and the impact of patterning on the yield of the light emitting units 13 can be reduced. In the manufacturing process of the light emitting unit 13 of the last color, the light emitting functional layer 132 and the second electrode 133 located in the non-display area NA are reserved to form the light emitting material layer 1320 and the shield layer 14, so that the light emitting material layer 1320 and the shield layer 14 can be manufactured according to the original manufacturing process, and there is no need to add new materials in the manufacturing process, so that the manufacturing cost can be saved.

[0092] The present application further provides a display device 2, which includes any of the display panels 1 according to the above embodiments of the present application, as shown in Fig. 9. The touch wiring 151 in the display device 2 and the portion of the signal line in the substrate 11 located in the non-display area NA can achieve a good shielding effect, thereby reducing interference therebetween and improving the yield of the display device 2.

[0093] The display device 2 may be a mobile terminal such as a mobile phone or a notebook computer, or a fixed terminal such as a television or a personal computer display, or may be a wearable device such as a wristwatch, and the present application is not particularly limited thereto.

[0094] The present application further provides a method for manufacturing a display panel including a display area and a non-display area surrounding at least a part of the display area. As shown in FIG. 10, the method includes the following steps:

[0095] A substrate 11 is provided in S100.

[0096] In S200, an isolation structure 12 is formed on one side of a substrate 11, and the isolation structure 12 includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NAAA, and the first portion 121 surrounds and forms a first opening 1211, and the second portion 122 surrounds and forms a second opening 1221.

[0097] In S300, the light emitting unit 13 is formed in the first opening.

[0098] In S400, a shield layer 14 is formed on the side of the isolation structure 12 away from the substrate 11, and at least a portion of the shield layer 14 is formed in the second opening 1221 and electrically connected to the second portion 122.

[0099] In S500, the shield layer 14, the light emitting unit 13 and the conductive layer on the side of the isolation structure 12 away from the substrate 11 are formed.

[0100] In a display panel manufactured by the manufacturing method according to the present application, second portion 122 located in the non-display area NA in the isolation structure and shield layer 14 can form a continuous film layer, realizing mutual shielding between the portion of conductive layer 15 located in the non-display area NA and signal line 111 in the non-display area NA of substrate 11, reducing mutual interference between signals in the portion of conductive layer 15 located in the non-display area NA and signals in signal line 111 in substrate 11, and improving the yield of display panel 1. This can further improve the user experience.
