[0043] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0044] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] When preparing the light-emitting functional layer of the display panel, it is necessary to pre-set a planarization layer on the substrate, then set a pixel definition layer on the planarization layer, and pattern the pixel definition layer to prepare pixel openings, and set an isolation structure, a light-emitting functional layer and a conductive layer (such as an anode) covering the light-emitting functional layer on the pixel definition layer.

[0046] The applicant further studied the process of the pixel definition layer and found that gas will be generated in the flattened pixel definition layer of organic material. In order to discharge the gas, a vent hole is usually set on the pixel definition layer located in the frame area. The vent hole extends along the thickness of the display panel, and the side wall of the vent hole is perpendicular or approximately perpendicular to the flattened layer. In this way, the continuity of the conductive layer deposited subsequently is poor. When the light-emitting functional layer and the conductive layer are patterned, etching (such as dry etching) is easy to damage the pixel definition layer in the area around the vent hole, resulting in the exposed conductive layer (such as the shielding layer provided at the same layer as the anode) covered by it (such as exposing the side). In this way, the exposed conductive layer is easily damaged during wet etching. When the display panel is equipped with a touch layer, the damaged conductive layer cannot play the preset role (such as shielding the signal), resulting in the GIP circuit (gate drive circuit) located below the conductive layer interfering with the touch signal of the touch layer located above the conductive layer, causing abnormal control of the touch layer.

[0047] Based on this, on one hand, the present application provides a display panel and a method for manufacturing the same, and a display device to solve the above problems. See the following embodiments for details.

[0048] like Figure 2A As shown, the display panel 1 includes a substrate 10, a first conductive layer 50, a first insulating layer 60 and a filling portion 110. The first conductive layer 50 is disposed on the substrate 10, and the first conductive layer 50 is provided with a first opening 51. At least part of the first insulating layer 60 is located on a side of the first conductive layer 50 away from the substrate 10, and the first insulating layer is provided with a second opening; the orthographic projection of the first opening on the substrate 10 overlaps with the orthographic projection of the second opening on the substrate 10. At least part of the filling portion is located in the second opening.

[0049] The first insulating layer is provided with a second opening connected to the first opening. At the same time, the first opening and the second opening can be used as vents to discharge the gas generated by the organic layer between the first insulating layer 60 and the substrate 10 during the process of preparing the light-emitting device 70. At least part of the filling portion is filled in the second opening 62, thereby protecting the second opening 62 and preventing the first conductive layer 50 at the first opening 51 from being damaged in subsequent processes.

[0050] Specifically, Figure 1 FIG. 1 is a schematic diagram of the structure of a display panel 1 according to an embodiment of the present application.

[0051] The display panel 1 includes a display area AA and a non-display area NA. For example, the non-display area NA surrounds at least a portion of the display area AA.

[0052] The display panel 1 has a display area AA and a non-display area NA connected to the display area AA. A plurality of light-emitting devices 70 are provided in the display area AA, and each light-emitting device 70 can emit light independently, thereby forming a display image in the display area AA. A gate drive circuit and a plurality of signal lines are provided in the non-display area NA, and the signal lines are electrically connected to the gate drive circuit. The output end of the gate drive circuit is connected to the pixel circuit in the display area AA, and the pixel circuit is electrically connected to the light-emitting device 70 located in the display area AA. Electronic devices such as flexible printed circuits (FPC) and driver chips (ICs) can provide clock signals, power signals, etc. to the gate drive circuit through signal lines, and can also send data signals to the display area AA through data lines according to display requirements. The pixel circuit of the display area AA can light up the corresponding light-emitting device 70 according to the data signal, thereby realizing the control of the display screen.

[0053] Furthermore, if Figure 2A and Figure 2BAs shown in , the first opening 51 in the first conductive layer 50 and the second opening 62 in the first insulating layer 60 are both located in the non-display area NA. The orthographic projection of the second opening 62 on the substrate 10 is located within the orthographic projection of the first opening 51 on the substrate 10, and the orthographic projection area of ​​the second opening 62 on the substrate 10 is smaller than the orthographic projection area of ​​the first opening 51 on the substrate 10. The first insulating layer 60 covers the side wall of the first conductive layer 50 facing the first opening 51. For example, the first insulating layer 60 includes an inorganic material.

[0054] The display panel 1 further includes a touch layer 100, which is disposed on a side of the first insulating layer 60 away from the substrate 10. The touch layer 100 includes at least one touch line 101 located in the non-display area NA, and the orthographic projection of the touch line 101 on the substrate 10 at least partially overlaps with the orthographic projection of the first conductive layer 50 on the substrate 10. The touch line 101 can be used to transmit a touch signal.

[0055] The substrate 10 can be a flexible substrate or a flexible substrate, and its material can be selected from polyimide (PI), polyethylene naphthalate (PEN) or polyethylene terephthalate (PET), etc. The material can also be a mixture of the above materials, or the substrate 10 can be a hard substrate 10, which can be selected from glass material.

[0056] For example, the display panel further includes: a driving layer 20 , which is disposed between the substrate 10 and the first insulating layer 60 , and at least a portion of the driving layer 20 is located in the non-display area NA.

[0057] The driving layer 20 includes a gate driving circuit located in the non-display area NA, and the gate driving circuit includes a scanning circuit 22 and / or a light-emitting control circuit 21. The scanning circuit 22 can be located on a side of the light-emitting control circuit 21 away from or close to the display area AA. The light-emitting control circuit 21 is spaced apart from the scanning circuit 22. The scanning circuit 22 (also called a scan circuit) is electrically connected to a pixel driving circuit located in the display area AA. The light-emitting control circuit 21 (also called an EM circuit) is electrically connected to a corresponding pixel driving circuit. In this embodiment, the gate driving circuit is arranged on opposite sides of the display area AA. In other embodiments, the gate driving circuit may be arranged only on one side of the display area AA.

[0058] For example, the orthographic projection of the touch line 101 on the substrate 10 covers at least part of the orthographic projection of the gate drive circuit on the substrate 10. For example, the overlapping area of ​​the orthographic projection of the touch line 101 on the substrate 10 and the orthographic projection of the gate drive circuit on the substrate 10 overlaps with the orthographic projection of the first conductive layer 50 on the substrate 10. The first conductive layer 50 can be used as a shielding layer to shield the signal interference between the touch line 101 and the gate drive circuit. For example, the first conductive layer 50 is connected to the power supply voltage or the DC voltage.

[0059] Further, the touch layer 100 includes at least two touch lines 101, and the orthographic projection of at least part of the touch lines 101 on the driving layer 20 covers at least part of the scanning circuit 22, and the orthographic projection of at least part of the touch lines 101 on the driving layer 20 covers at least part of the light-emitting control circuit 21. The orthographic projection of the second opening 62 and / or the first opening on the substrate 10 partially overlaps with the orthographic projection of the gap between two adjacent touch lines 101 on the substrate 10, for example, the orthographic projection of the second opening 62 and / or the first opening on the substrate 10 is located between the orthographic projections of the gap between two adjacent touch lines 101 on the substrate 10. The orthographic projection of the gap between the scanning circuit 22 and the light-emitting control circuit 21 on the substrate 10 overlaps with the orthographic projection of the second opening 62 and / or the first opening on the substrate 10. In this way, the setting of the second opening and the first opening can reduce the influence of the setting of the second opening and the first opening on the shielding effect between the shielding touch line 101 and the gate driving circuit.

[0060] For example, the filling portion 110 fills the second opening 62, and the surface of the filling portion 110 away from the substrate 10 is flush with the surface of the first insulating layer 60 away from the substrate 10 (i.e., located in the same plane). The material of the filling portion 110 may include an organic material, such as an organic glue. By providing the filling portion 110 to protect the second opening 62, the first insulating layer 60 around the second opening 62 will not be damaged in subsequent processes, thereby preventing the first conductive layer 50 from being exposed in the second opening 62, thereby preventing the signal transmitted in the gate drive circuit from interfering with the touch signal transmitted by the touch wiring 101 in the touch layer 100, and improving the stability and accuracy of the touch layer 100.

[0061] For example, the display panel 1 further includes a first organic layer 40, which is disposed between the driving layer 20 and the first conductive layer 50. The first organic layer 40 may be a planarization layer. The first opening and the second opening may serve as vents to discharge gas generated by the first organic layer between the first insulating layer 60 and the substrate 10 during the preparation of the light-emitting device 70.

[0062] A first organic layer 40 and / or a planarization layer 30 for planarizing the surface of the driving layer 20 is provided on the side of the driving layer 20 away from the substrate 10. The first organic layer 40 and / or the planarization layer 30 covers the display area AA, and at least a portion of the first organic layer 40 and / or the planarization layer 30 extends from the display area AA to cover the driving layer 20 located in the non-display area NA.

[0063] Specifically, the first conductive layer 50 is disposed on the side of the first organic layer 40 and / or the planarization layer 30 away from the substrate 10, and the first conductive layer 50 can be connected to a power supply voltage or a DC voltage. The gate drive circuit and the touch layer 100 are respectively on the upper and lower sides of the first conductive layer 50, and the first conductive layer 50 can be used as a shielding layer to isolate the gate drive circuit from the touch layer 100, so as to prevent the touch signal transmitted in the touch layer 100 from crosstalking with the signal transmitted in the gate drive circuit, thereby preventing the occurrence of abnormal touch.

[0064] The driving layer 20 may include a pixel driving circuit located in the display area AA, and the gate driving circuit is electrically connected to the pixel driving circuit. The pixel driving circuit is electrically connected to the light-emitting device 70 in the display function layer to control the on / off state and the light-emitting brightness of the light-emitting device 70 based on the instruction. The pixel driving circuit may be composed of a combination of a plurality of transistors TFT, capacitors, etc., and its topology is a 7T1C circuit, a 7T2C circuit, an 8T1C circuit or an 8T2C circuit, etc., which is not limited here, so as to realize driving the light-emitting device 70.

[0065] In an embodiment of the present invention, the first insulating layer 60 is a pixel defining layer 60 (the pixel defining layer 60 described below is the first insulating layer 60), and the pixel defining layer 60 is arranged on the side of the planarization layer 30 away from the substrate 10, and at least a portion of the pixel defining layer 60 is located on the side of the first conductive layer 50 away from the substrate 10.

[0066] For example, the display panel further includes a light emitting device 70, the first insulating layer 60 is provided with a pixel opening 61, and at least a portion of the light emitting device 70 is located in the pixel opening 61. Specifically, in the display area AA, a plurality of pixel openings 61 are provided in the pixel defining layer 60, and at least a portion of the light emitting device 70 is located in the corresponding pixel opening 61. The material of the pixel defining layer 60 includes an inorganic material.

[0067] Furthermore, if Figure 3As shown in the figure, the light-emitting device 70 is located in the display area AA and is electrically connected to the corresponding pixel driving circuit. The light-emitting device 70 includes a first electrode 71, a light-emitting functional layer 72 and a second electrode 73 which are stacked in sequence along a direction Z away from the substrate 10. The first electrode 71 is located in the display area AA and is also arranged on the side of the planarization layer 30 away from the substrate 10. The first electrode 71 is arranged in the same layer as the first conductive layer 50, that is, the first electrode 71 and the first conductive layer 50 can be prepared by the same film layer process, and the materials are also the same to simplify the process. At least part of the first electrode 71 is located between the pixel defining layer 60 and the planarization layer 30, and the pixel opening 61 exposes at least part of the first electrode 71. The light-emitting functional layer 72 is arranged on the side of the first electrode 71 away from the substrate 10, and covers the exposed surface of the first electrode 71 in the corresponding pixel opening 61. The second electrode 73 is stacked and arranged on the side of the light-emitting functional layer 72 away from the substrate 10.

[0068] For example, the display panel 1 further includes an isolation structure 80, which encloses a plurality of isolation openings 81, for example, the isolation openings 81 are connected to the corresponding pixel openings 61, at least a portion of the light-emitting device 70 is located in the corresponding isolation openings 81, and the second electrode 73 of the light-emitting device 70 is electrically connected to the isolation structure 80. For example, at least a portion of the isolation structure 80 is disposed in the same layer as the filling portion. Multiple structures disposed in the same layer can be obtained by patterning the same film layer to simplify the process. The isolation structure 80 may include a conductive material. The isolation structure 80 may be located on a side of the first insulating layer or the pixel defining layer away from the substrate 10, or the first insulating layer or the pixel defining layer is provided with a clearance opening, and the isolation structure 80 may be located in the clearance opening.

[0069] For example, the isolation structure 80 includes a first isolation layer 82 and a second isolation layer 83. The second isolation layer 83 is stacked on the side of the first isolation layer 82 away from the substrate 10. The first isolation layer 82 and the second isolation layer 83 surround the isolation opening 81. The first isolation layer 82 is disposed on the side of the first insulating layer 60 (e.g., a pixel defining layer) away from the substrate 10. The materials of the first isolation layer 82 and the second isolation layer 83 include conductive materials; for example, the material of the first isolation layer 82 can be aluminum, and the material of the second isolation layer 83 can be titanium. The second electrode 73 of the light-emitting device 70 extends from the surface of the light-emitting functional layer 72 away from the substrate 10 to the side wall of the first isolation layer 82, thereby causing the second electrode 73 to be electrically connected to the first isolation layer 82, and the second electrode 73 can obtain the VSS power supply signal through the first isolation layer 82. Among them, the cross-sectional profile of the first isolation layer 82 located between two adjacent isolation openings 81 in the stacking direction of the display panel 1 is trapezoidal, and the width of the first isolation layer 82 on the side close to the second isolation layer 83 is smaller than the width on the side close to the substrate 10, so as to facilitate the climbing of the second electrode 73 and reduce the difficulty of overlapping between the second electrode 73 and the first isolation layer 82.

[0070] Furthermore, the orthographic projection of the side of the first isolation layer 82 away from the substrate 10 on the substrate 10 is located within the orthographic projection range of the second isolation layer 83 on the substrate 10, and the end of the second isolation layer 83 facing the isolation opening 81 is protruded from the first isolation layer 82, so that the second isolation layer 83 can completely cover the first isolation layer 82, and thus when preparing the light-emitting functional layer 72, it can prevent the material of the light-emitting functional layer 72 from being evaporated onto the first isolation layer 82. When preparing the second electrode 73, by adjusting the evaporation angle, the coverage area of ​​the second electrode 73 can be larger than the coverage area of ​​the light-emitting functional layer 72, so that the second electrode 73 can extend from the surface of the light-emitting functional layer 72 to cover the side wall of the first isolation layer 82, thereby improving the overlap yield between the second electrode 73 and the first isolation layer 82.

[0071] Further, the isolation structure 80 also includes a third isolation layer 84, which is disposed between the substrate 10 and the first isolation layer 82. The orthographic projection of the first isolation layer 82 on the substrate 10 is located within the orthographic projection range of the third isolation layer 84 on the substrate 10. The third isolation layer 84 is disposed between the first insulating layer (e.g., a pixel defining layer) and the first isolation layer 82. The second electrode 73 is also overlapped with the third isolation layer 84. The orthographic projection of the third isolation layer 84 on the substrate 10 is located within the orthographic projection range of the second isolation layer 83 on the substrate 10. The material of the third isolation layer 84 also includes a metal material, for example: the material of the third isolation layer 84 may be molybdenum.
