Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0114] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0115] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0116] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0117] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0118] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0132] For example, at least one film layer in the light-emitting functional layer 21 is broken at the blocking structure 14C, so that the broken film layer in the light-emitting functional layer 21 is a discontinuous structure at the blocking structure 14C. Even if the light-emitting functional layer 21 is partially attached to the sidewall of the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device, the lateral flow of charge in the light-emitting device 20 (lateral leakage) can be avoided or improved. For example, the flow of charge between the light-emitting functional layer 21 and the isolation structure 15 can be avoided or improved, thereby preventing the lateral flow or escape of charge in the light-emitting functional layer 21 through the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device 20 (lateral leakage). This can improve the luminous efficiency of the light-emitting device 20 and improve the display quality of the display panel.

[0133] In this embodiment, a blocking structure 14C is provided between the isolation structure 15 located on one side of the light-emitting device 20 and the center of the light-emitting device 20, and at least one film layer in the light-emitting functional layer 21 is broken at the blocking structure 14C. On the one hand, this makes the broken film layer in the light-emitting functional layer 21 a discontinuous structure at the blocking structure 14C. Even if the light-emitting functional layer 21 partially overlaps the sidewall of the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device, it can avoid or improve the lateral flow of charge in the light-emitting device 20. For example, it can avoid or improve the flow of charge between the light-emitting functional layer 21 and the isolation structure 15, thereby preventing the charge from flowing laterally or escaping in the light-emitting functional layer 21 through the blocking structure 14C on the side of the isolation structure 15 away from the center of the light-emitting device 20, thereby improving the luminous efficiency of the light-emitting device 20 and enhancing the display quality of the display panel. On the other hand, no blocking structure 14C is provided between the isolation structure 15 located on one side of the light-emitting device 20 and the center of the light-emitting device 20. The second electrode 22 of the light-emitting device 20 can be connected to the isolation structure 15 on the side without the blocking structure 14C. When the isolation structure 15 is a conductive structure, it is convenient to provide an electrical signal to the second electrode 22 through the isolation structure 15 on the side without the blocking structure 14C.

[0134] In some embodiments, the two adjacent and oppositely arranged isolation structures 15 on both sides of the light-emitting device 20 respectively include a first isolation sidewall 15a and a second isolation sidewall 15b. On the plane parallel to the array substrate 10, the blocking structure 14C is located between the first isolation sidewall 15a and the center of the light-emitting device 20; the second electrode 22 of the light-emitting device 20 is attached to the second isolation sidewall 15b.

[0135] For example, such as Figure 3 , Figure 6 and Figure 8 As shown, the light-emitting device 20 has two opposing isolation structures 15 on both sides. The two side walls of the two isolation structures 15 facing the light-emitting device 20 are respectively the first isolation side wall 15a and the second isolation side wall 15b, that is, Figure 1 As shown, a blocking structure 14C is provided between one of the first isolation sidewall 15a and the second isolation sidewall 15b and the center (or central region, or light-emitting region) of the light-emitting device 20, while no blocking structure 14C is provided between the other of the first isolation sidewall 15a and the center (or central region, or light-emitting region) of the light-emitting device 20. Figures 1 to 9 An example is provided where a blocking structure 14C is provided between the first isolation sidewall 15a and the center (or central region, or light-emitting region) of the light-emitting device 20.

[0136] For example, such as Figure 3 , Figure 6 and Figure 8 As shown, the first isolation structure 15K1 includes a first isolation sidewall 15a facing the light-emitting device 20, and the second isolation structure 15K2 includes a second isolation sidewall 15b facing the light-emitting device 20.

[0137] For example, such as Figure 3 , Figure 6 and Figure 8 As shown by the elliptical dashed line 101, the second electrode 22 of the light-emitting device 20 is attached to the second isolation sidewall 15b. When the second isolation structure 15K2 is a conductive structure, it is convenient to provide an electrical signal to the second electrode 22 through the second isolation structure 15K2.

[0138] Optionally, in some embodiments, all film layers in the light-emitting functional layer 21 are disconnected at the blocking structure 14C.

[0139] For example, all film layers in the light-emitting functional layer 21 are disconnected at the blocking structure 14C, which can better prevent or improve the lateral flow of charge in the light-emitting device 20. For example, it can better prevent or improve the flow of electrical signals between the light-emitting functional layer 21 and the isolation structure 15, thereby preventing the charge from flowing laterally or escaping (lateral leakage) in the light-emitting functional layer 21 through the first isolation sidewall 15a. This can improve the luminous efficiency of the light-emitting device 20 and enhance the display quality of the display panel.

[0140] Optionally, in some embodiments, all film layers in the light-emitting functional layer 21 and the second electrode 22 are disconnected at the blocking structure 14C.

[0141] For example, all film layers in the light-emitting functional layer 21 and the second electrode 22 are disconnected at the blocking structure 14C. On the one hand, this can further prevent or improve the lateral flow of charge in the light-emitting device 20. For example, it can better prevent or improve the lateral flow or escape of charge in the light-emitting functional layer 21 through the first isolation sidewall 15a, thereby improving the luminous efficiency of the light-emitting device 20 and enhancing the display quality of the display panel. On the other hand, it can also prevent or improve other forms of lateral charge flow. For example, the second isolation structure 15K2 provides an electrical signal to the second electrode 22, and can also prevent the electrical signal from being transmitted from the first electrode portion 221 (the portion of the second electrode 22 located on the side of the blocking structure 14C away from the first isolation sidewall 15a) to the second electrode portion 222 (the portion of the second electrode 22 located on the side of the blocking structure 14C away from the second isolation sidewall 15b) and then flowing out through the first isolation structure 15K1 (without reaching the light-emitting layer), thereby improving the luminous efficiency of the light-emitting device 20 and enhancing the display quality of the display panel.

[0142] In some embodiments, the light-emitting functional layer 21 includes a first light-emitting functional part 211 and a second light-emitting functional part 212. The first light-emitting functional part 211 is located on the side of the blocking structure 14C away from the first isolation sidewall 15a, and the second light-emitting functional part 212 is located on the side of the isolation structure 15 away from the second isolation sidewall 15b. The first light-emitting functional part 211 in at least a portion of the light-emitting device 20 is spaced apart from the second isolation sidewall 15b, and the second electrode 22 covers the edge of the first light-emitting functional part 211 away from the first isolation sidewall 15a.

[0143] For example, in the direction of the first isolation sidewall 15a toward the light-emitting device 20, the first light-emitting functional part 211 and the second light-emitting functional part 212 are located on both sides of the blocking structure 14C, and the first light-emitting functional part 211 covers the center of the light-emitting device.

[0144] For example, such as Figure 3 , Figure 6 and Figure 8 As shown by the elliptical dashed line 101, at least a portion of the first light-emitting functional part 211 in the light-emitting device 20 is spaced apart from the second isolation sidewall 15b. The second electrode 22 covers the edge of the first light-emitting functional part 211 away from the first isolation sidewall 15a, which facilitates the second electrode 22 to overlap with the second isolation sidewall 15b, prevents the first light-emitting functional part 211 from separating the second electrode 22 from the second isolation sidewall 15b, and increases the area of ​​the second electrode 22 overlapping with the second isolation sidewall 15b, reducing the contact resistance between the second electrode 22 and the second isolation sidewall 15b, and preventing uneven display.

[0145] In some embodiments, at least a portion of the second light-emitting functional part 212 in the light-emitting device 20 is attached to the first isolation sidewall 15a.

[0146] For example, in some embodiments, during the fabrication of the display panel 100, during the formation of the light-emitting functional layer 21, in order to ensure that the first light-emitting functional part 211 in the light-emitting device 20 is spaced apart from the second isolation sidewall 15b, or to ensure that the second electrode 22 is directly attached to the second isolation sidewall 15b, it is necessary to control the evaporation angle of the light-emitting functional layer 21. For example, the evaporation angle is towards the first isolation sidewall 15a, resulting in at least a portion of the second light-emitting functional part 212 in the light-emitting device 20 being attached to the first isolation sidewall 15a. However, the second light-emitting functional part 212 being attached to the first isolation sidewall 15a will cause some charge to flow laterally in the light-emitting functional layer 21 and be lost. For example, the charge provided to the second electrode 22 by the second isolation structure 15K2 may not reach the light-emitting functional layer but flow directly to the first isolation structure 15K1, resulting in charge loss, reducing the luminous efficiency of the light-emitting device 20, and thus causing a decrease in the image quality of the display panel. The blocking structure 14C of this application can prevent or improve the lateral flow of charge in the light-emitting functional layer 21, thereby improving the luminous efficiency of the light-emitting device 20 and enhancing the display quality of the display panel.

[0147] Optionally, in some embodiments, the orthographic projection of the second light-emitting functional part 212 on the array substrate 10 covers the orthographic projection of the edge of the second electrode 22 near the first isolation sidewall 15a on the array substrate 10.

[0148] For example, such as Figure 3 , Figure 6 and Figure 8 As shown by the dashed rectangle 102, during the fabrication of the display panel 100, in the formation of the second electrode 22, to ensure that the second electrode 22 directly contacts the second isolation sidewall 15b, the formation angle of the second electrode 22 needs to be controlled. For example, during the vapor deposition process to form the second electrode 22, the vapor deposition angle is controlled to face the second isolation sidewall 15b. This results in the second electrode 22 not directly contacting the first isolation sidewall 15a. Consequently, at least a portion of the second light-emitting functional part 212 of the light-emitting device 20 contacts the first isolation sidewall 15a, while the second electrode 22 does not. This can easily lead to lateral charge flow in the light-emitting functional layer 21, resulting in charge loss and reduced luminous efficiency of the light-emitting device 20, thus degrading the display panel's image quality. The blocking structure 14C of this application can avoid or improve the lateral charge flow in the light-emitting functional layer 21, thereby improving the luminous efficiency of the light-emitting device 20 and enhancing the display panel's image quality.

[0149] In some embodiments, the isolation structure 15 includes a support portion 152 and a crown portion 153 sequentially stacked on the array substrate 10, wherein the orthographic projection of the support portion 152 on the array substrate 10 is located within the orthographic projection of the crown portion 153 on the array substrate 10; the first isolation sidewall 15a and the second isolation sidewall 15b are both sidewalls of the support portion 152 of the corresponding isolation structure 15.

[0150] Optionally, the support portion 152 and the crown portion 153 are integrally formed.

[0151] Alternatively, the support portion 152 and the crown portion 153 may be made of different materials.

[0152] Optionally, the support portion 152 includes a conductive material.

[0153] For example, the isolation structure 15 includes a support portion 152 and a crown portion 153 sequentially stacked on the array substrate 10, with the orthographic projection of the support portion 152 on the array substrate 10 located within the orthographic projection of the crown portion 153 on the array substrate 10. Thus, the portion of the isolation structure 15 at least away from the substrate 11 is configured with a shape that is wider at the top and narrower at the bottom, allowing the isolation structure 15 to block other film layers such as the light-emitting functional layer 21 or hole transport layer HTL of adjacent light-emitting devices 20. This saves on expensive fine metal mask (FMM), thereby reducing the manufacturing cost of the display panel. At the same time, without the use of a fine metal mask (FMM), the light-emitting area of ​​the sub-pixels is not limited by the opening of the fine metal mask, allowing the light-emitting area of ​​the sub-pixels to be made smaller, and a greater number of sub-pixels can be formed in the display panel, thereby improving the resolution of the display panel.

[0154] For example, the support portion 152 and the crown portion 153 can be a multi-layered stacked structure, which facilitates the use of different materials for each. For example, the support portion 152 is designed to be a conductive material, and the crown portion 153 is designed to be an insulating material. For example, the support portion 152 is designed to be a conductive material, and the crown portion 153 is designed to be a conductive material, but the etching rate of the support portion 152 is greater than the etching rate of the crown portion 153. For example, the support portion 152 and the crown portion 153 can be configured as an integral structure to increase the robustness of the isolation structure 15.

[0155] For example, the support portion 152 includes at least one metal layer. In one example, the support portion 152 includes one metal layer. Further, the material of the support portion 152 includes at least one of a metal and a metal oxide. Exemplarily, the metal may be silver, copper, titanium, aluminum, etc. The metal oxide may be tin oxide, zinc oxide, cadmium oxide, indium oxide, indium tin oxide, zinc indium oxide, zinc gallium oxide, zinc aluminum oxide, titanium tantalum oxide, etc.

[0156] For example, the crown 153 may be made of titanium or molybdenum.

[0157] For example, Figure 1 The diagram illustrates that the isolation structure 15 includes a pad 151, a support 152, and a crown 153. The pad 151, support 152, and crown 153 can be formed into shapes such as "I" or "T". The material of the pad 151 includes titanium or molybdenum, but is not limited to these.

[0158] For example, Figure 1 The diagram illustrates that the isolation structure 15 is a stacked structure of a pad 151, a support 152, and a crown 153. For example, the stacked structure of the isolation structure 15 can be titanium / aluminum / titanium or molybdenum / aluminum / molybdenum, with the pad 151 made of titanium or molybdenum, the support 152 made of aluminum, and the crown 153 made of titanium or molybdenum. By setting the stacked three metal layers, the resistance of the isolation structure 15 can be reduced, thereby reducing the power consumption of the display panel 100.

[0159] For example, such as Figures 1 to 8 As shown, the first isolation sidewall 15a and the second isolation sidewall 15b are both sidewalls of the support portion 152 of the corresponding isolation structure 15, that is, the first isolation sidewall 15a is the sidewall of the support portion 152 of the first isolation structure 15K1 (e.g. Figure 1 As shown in the first support sidewall 152a), the second isolation sidewall 15b is the sidewall of the support part 152 of the second isolation structure 15K2 (as shown in the first support sidewall 152a). Figure 1 (As shown in the side wall 152b of the second support portion). When the support portion 152 is made of conductive material, the second electrode 22 is attached to the side wall (side wall 152b) of the support portion 152 of the second isolation structure 15K2, and the second isolation structure 15K2 can provide an electrical signal to the second electrode 22.

[0160] Please see Figures 1 to 3 .

[0161] In some implementations, such as Figures 1 to 3 As shown, the display panel 100 also includes a first insulating layer 14J disposed between the array substrate 10 and the isolation structure 15; the blocking structure 14C includes at least one groove 14C1 located in the first insulating layer 14J.

[0162] For example, at least one groove 14C1 located in the first insulating layer 14J can be provided as a blocking structure 14C, so that at least one film layer in the light-emitting functional layer 21 is disconnected at the groove 14C1, which can avoid or improve the lateral flow of charge in the light-emitting functional layer 21, thereby improving the luminous efficiency of the light-emitting device 20 and enhancing the display quality of the display panel.

[0163] Alternatively, in some implementations, such as Figures 1 to 3As shown, along the direction of the first isolation sidewall 15a toward the corresponding light-emitting device 20, the cross-section of the groove 14C1 is at least rectangular and trapezoidal.

[0164] For example, in the direction opposite to the first isolation sidewall 15a and the second isolation sidewall 15b, the cross section of the groove 14C1 is at least rectangular and trapezoidal, which can make the light-emitting functional layer 21 more disconnected at the groove 14C1.

[0165] For example, Figure 1 The diagram illustrates that the cross-section of the groove 14C1 is rectangular along the direction from the first isolation sidewall 15a toward the corresponding light-emitting device 20; Figure 2 The diagram illustrates that the cross-section of the groove 14C1 is trapezoidal along the direction from the first isolation sidewall 15a toward the corresponding light-emitting device 20.

[0166] Alternatively, in some implementations, such as Figures 1 to 3 As shown, the sidewall of the groove 14C1 includes a first groove sidewall 14C11 facing an adjacent light-emitting device 20 and a second groove sidewall 14C12 away from an adjacent light-emitting device 20.

[0167] Alternatively, in some implementations, such as Figures 1 to 3 As shown, at least one of the first groove sidewall 14C11 and the second groove sidewall 14C12 forms an angle of less than or equal to 90 degrees with the bottom surface of the groove 14C1.

[0168] For example, such as Figure 1 The diagram illustrates that the angle between the sidewall 14C11 of the first groove and the bottom surface of the groove 14C1 is the first groove angle α1, which is less than or equal to 90 degrees. For example, the first groove angle α1 can be any value among 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0169] For example, such as Figure 1 The diagram illustrates that the included angle between the sidewall 14C12 of the second groove and the bottom surface of the groove 14C1 is the included angle α2 of the second groove. The included angle α2 of the second groove is less than or equal to 90 degrees. For example, the included angle α1 of the first groove can be any value among 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0170] For example, the angle between at least one of the first groove sidewall 14C11 and the second groove sidewall 14C12 and the bottom surface of the groove 14C1 is less than or equal to 90 degrees, which allows the light-emitting functional layer 21 to be better disconnected in the groove 14C1.

[0171] In some implementations, such as Figures 1 to 3 As shown, in the direction along the first isolation sidewall 15a toward the corresponding light-emitting device 20, the size of the groove 14C1 is smaller than the size of the isolation structure 15.

[0172] For example, such as Figure 1 As shown, in the direction along the first isolation sidewall 15a toward the corresponding light-emitting device 20, the size of the groove 14C1 (the width of the groove 14C1 at the end near the substrate 11) is the groove width d2, and the size (width) of the isolation structure 15 is the first width d1. The groove width d2 is smaller than the first width d1, which can prevent the blocking structure 14C from occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting area of ​​the light-emitting device 20, or beneficial to increasing the resolution of the display panel.

[0173] Alternatively, in some implementations, such as Figures 1 to 3 As shown, in the direction perpendicular to the plane of the array substrate 10, the size of the groove 14C1 is smaller than the size of the isolation structure 15.

[0174] For example, such as Figure 1 As shown, in the direction perpendicular to the plane of the array substrate 10, the size of the groove 14C1 is the groove height h2, and the size (height) of the isolation structure 15 is the first height h1. The groove height h2 is smaller than the first height h1. The smaller groove height h2 makes it easier to manufacture the groove 14C1 with a groove width d2 smaller than the first width d1. This can prevent the blocking structure 14C from occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting area of ​​the light-emitting device 20 or improving the resolution of the display panel.

[0175] Optionally, in a direction perpendicular to the plane of the array substrate 10, the groove 14C1 does not penetrate the first insulating layer 14J.

[0176] For example, such as Figure 1 As shown, in the direction perpendicular to the plane of the array substrate 10, the groove 14C1 does not penetrate the first insulating layer 14J. In the display panel 100, in the direction perpendicular to the plane of the array substrate 10, the first insulating layer 14J also serves to insulate and isolate the film layers on both sides. Since the groove 14C1 does not penetrate the first insulating layer 14J, it can completely prevent the light-emitting functional layer 21 or / and the second electrode 22 from contacting the film layer of the first insulating layer 14J on the side near the lower substrate 11.

[0177] Please see Figures 4 to 6 .

[0178] In some implementations, such as Figures 4 to 6As shown, the display panel 100 also includes a first insulating layer 14J disposed between the array substrate 10 and the isolation structure 15; the blocking structure 14C includes at least one protrusion structure 14D1 located on the side of the first insulating layer 14J away from the array substrate 10.

[0179] For example, at least one protrusion structure 14D1 located on the side of the first insulating layer 14J away from the array substrate 10 can be provided as a blocking structure 14C, so that at least one film layer in the light-emitting functional layer 21 is broken at the groove 14C1, which can avoid or improve the lateral flow of charge in the light-emitting functional layer 21, thereby improving the luminous efficiency of the light-emitting device 20 and improving the display quality of the display panel.

[0180] Alternatively, in some implementations, such as Figures 4 to 6 As shown, along the direction of the first isolation sidewall 15a toward the light-emitting device 20, the cross-section of the protrusion structure 14D1 is rectangular or inverted trapezoidal.

[0181] For example, the cross-section of the protrusion structure 14D1 is rectangular or inverted trapezoidal along the direction of the first isolation sidewall 15a toward the light-emitting device 20, which allows the light-emitting functional layer 21 to be better disconnected at the protrusion structure 14D1.

[0182] For example, Figure 4 The diagram illustrates that the cross-section of the protruding structure 14D1 is rectangular along the direction from the first isolation sidewall 15a toward the light-emitting device 20; Figure 5 The diagram illustrates that the cross-section of the protruding structure 14D1 is inverted trapezoidal along the direction from the first isolation sidewall 15a toward the light-emitting device 20.

[0183] Alternatively, in some implementations, such as Figures 4 to 6 As shown, the sidewall of the protrusion structure 14D1 includes a first protrusion sidewall 14D11 facing an adjacent light-emitting device 20 and a second protrusion sidewall 14D12 away from an adjacent light-emitting device 20.

[0184] Alternatively, in some implementations, such as Figures 4 to 6 As shown, at least one of the first protruding sidewall 14D11 and the second protruding sidewall 14D12 forms an angle of less than or equal to 90 degrees with the surface of the first insulating layer 14J away from the array substrate 10.

[0185] For example, such as Figure 4The angle between the first protruding sidewall 14D11 and the surface of the first insulating layer 14J away from the array substrate 10 is shown as the first protrusion angle β1. The first protrusion angle β1 is less than or equal to 90 degrees. For example, the first protrusion angle β1 is any value among 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0186] For example, such as Figure 5 The angle between the second protrusion sidewall 14D12 and the surface of the first insulating layer 14J away from the array substrate 10 is shown as the second protrusion angle β2. The second protrusion angle β2 is less than or equal to 90 degrees. For example, the second protrusion angle β2 is any value among 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0187] For example, the angle between at least one of the first protruding sidewall 14D11 and the second protruding sidewall 14D12 and the surface of the first insulating layer 14J away from the array substrate 10 is less than or equal to 90 degrees, which can make the light-emitting functional layer 21 better disconnected in the protruding structure 14D1.

[0188] In some implementations, such as Figures 4 to 6 As shown, in the direction parallel to the plane of the array substrate 10, the size of the protrusion structure 14D1 is smaller than the size of the isolation structure 15.

[0189] For example, such as Figure 4 As shown, in the direction parallel to the plane of the array substrate 10, and in the direction along the first isolation sidewall 15a toward the corresponding light-emitting device 20, the size of the protrusion structure 14D1 (the width of the end of the protrusion structure 14D1 away from the substrate 11) is the protrusion width d3, and the size (width) of the isolation structure 15 is the first width d1. The protrusion width d3 is smaller than the first width d1, which can prevent the blocking structure 14C from occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting area of ​​the light-emitting device 20, or beneficial to increasing the resolution of the display panel.

[0190] Alternatively, in some implementations, such as Figures 4 to 6 As shown, in the direction perpendicular to the plane of the array substrate 10, the size of the protrusion structure 14D1 is smaller than the size of the isolation structure 15.

[0191] For example, such as Figure 4As shown, in the direction perpendicular to the plane of the array substrate 10, the size of the protrusion structure 14D1 is the protrusion height h3, and the size (height) of the isolation structure 15 is the first height h1. The protrusion height h3 is smaller than the first height h1. The smaller the protrusion height h3, the easier it is to manufacture the protrusion structure 14D1 with a protrusion width d3 smaller than the first width d1. This can avoid the blocking structure 14C occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting area of ​​the light-emitting device 20, or to improving the resolution of the display panel.

[0192] Alternatively, in some implementations, such as Figures 4 to 6 As shown, the protrusion structure 14D1 and the first insulating layer 14J are an integral structure and can be formed in the same process, which simplifies the manufacturing process.

[0193] Please see Figure 7 and Figure 8 .

[0194] In some implementations, such as Figure 7 and Figure 8 As shown, the display panel 100 also includes a first insulating layer 14J disposed between the array substrate 10 and the isolation structure 15. The first insulating layer 14J includes a first insulating structure 14J1 and a plurality of first openings 14J2 surrounded by the first insulating structure 14J1. The light-emitting device 20 is at least partially housed in the corresponding first opening 14J2. The sidewall of the first insulating structure 14J1 includes a first opening sidewall 14J11 close to the side of the first isolation sidewall 15a and facing the light-emitting device 20. The blocking structure 14C is the first opening sidewall 14J11. The angle between the bottom surface of the first opening sidewall 14J11 and the first opening 14J2 is less than or equal to 90 degrees.

[0195] For example, such as Figure 7 As shown, the sidewall of the first insulating structure 14J1 includes a first opening sidewall 14J11 that is close to the first isolation sidewall 15a and faces the light-emitting device 20. The angle between the first opening sidewall 14J11 and the bottom surface of the first opening 14J2 is the first opening angle θ1. The first opening angle θ1 is less than or equal to 90 degrees, which allows the light-emitting functional layer 21 to be better disconnected at the first opening sidewall 14J11.

[0196] For example, such as Figure 7 As shown, the first opening angle θ1 is less than or equal to 90 degrees. For example, the first opening angle θ1 is any value among 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0197] Alternatively, in some implementations, such as Figure 7As shown, the sidewall of the first insulating structure 14J1 includes a second opening sidewall 14J12 that is close to the side of the second isolation sidewall 15b and faces the first opening 14J2. The angle between the second opening sidewall 14J12 and the bottom surface of the first opening 14J2 is greater than 90 degrees.

[0198] For example, such as Figure 7 As shown, the sidewall of the first insulating structure 14J1 includes a second opening sidewall 14J12 that is close to the second isolation sidewall 15b and faces the first opening 14J2. The angle between the second opening sidewall 14J12 and the bottom surface of the first opening 14J2 is the second opening angle θ2. The angle between the second opening sidewall 14J12 and the bottom surface of the first opening 14J2 is greater than 90 degrees, which allows the light-emitting functional layer 21 to extend continuously at the second opening sidewall 14J12, thereby preventing the second electrode 22 from breaking at the second opening sidewall 14J12.

[0199] For example, such as Figure 7 As shown, the second opening angle θ2 is greater than 90 degrees. For example, the second opening angle θ2 is any value among 100 degrees, 110 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, 150 degrees, and 160 degrees.

[0200] Optionally, the angle between the second opening sidewall 14J12 and the bottom surface of the first opening 14J2 is greater than or equal to 130 degrees.

[0201] For example, if the included angle θ2 of the second opening is greater than or equal to 130 degrees, the light-emitting functional layer 21 can be extended continuously at the sidewall 14J12 of the second opening, thereby better avoiding the breakage of the second electrode 22 at the sidewall 14J12 of the second opening.

[0202] Please see Figures 1 to 3 , Figures 4 to 6 ,or Figure 7 and Figure 8 .

[0203] In some implementations, such as Figures 1 to 3 , Figures 4 to 6 ,or Figure 7 and Figure 8 As shown, the first insulating layer 14J is a pixel definition layer 14, which includes a pixel definition structure 141 and a plurality of pixel openings 142 surrounding the pixel definition structure 141. The pixel definition structure 141 covers the edge of the corresponding first electrode 131, and the pixel openings 142 expose at least part of the first electrode 131. The isolation structure 15 is disposed on the side of the corresponding pixel definition structure 141 away from the array substrate 10.

[0204] For example, in some other implementations, the pixel definition structure 141 does not cover the edge of the corresponding first electrode 131.

[0205] For example, in some implementations, such as Figure 7 As shown, the first insulating layer 14J is the pixel definition layer 14, the first insulating structure 14J1 is the pixel definition structure 141, the first opening 14J2 is the pixel opening 142, and the first opening sidewall 14J11 is the sidewall of the pixel definition structure 141 near the first isolation sidewall 15a and facing the center of the light-emitting device 20 (e.g., Figure 7 The first pixel defining sidewall 1411), and the second opening sidewall 14J12 are the sidewalls of the pixel defining structure 141 near the second isolation sidewall 15b and facing the center of the light-emitting device 20 (e.g., the first pixel defining sidewall 1411), are the sidewalls of the pixel defining structure 141 that are close to the second isolation sidewall 15b and face the center of the light-emitting device 20 (e.g., the second Figure 7 The second pixel in the middle defines the sidewall 1412).

[0206] In some embodiments, the first isolation sidewalls 15a of different isolation structures 15 arranged in the same direction face the same direction.

[0207] Optionally, in some embodiments, the second isolation sidewalls 15b of the different isolation structures 15 arranged in the same direction face the same direction.

[0208] For example, in some embodiments, isolation structures 15 are provided on both sides of multiple light-emitting devices 20. At least some of the isolation structures 15 are arranged in the same direction. The first isolation sidewalls 15a of the different isolation structures 15 arranged in the same direction face the same direction, and the second isolation sidewalls 15b of the different isolation structures 15 arranged in the same direction face the same direction. In the manufacturing process, it is convenient to control the formation process of the light-emitting functional layer 21 and the second electrode 22, such as controlling a uniform evaporation angle, thereby simplifying the production process.

[0209] Optionally, in a direction parallel to the plane of the array substrate 10, the extending direction of the blocking structure 14C is parallel to the extending direction of the first isolation sidewall 15a.

[0210] For example, in some embodiments, the extension direction of the blocking structure 14C is parallel to the extension direction of the first isolation sidewall 15a in a direction parallel to the plane of the array substrate 10, or the extension direction of the blocking structure 14C is parallel to the extension direction of the first isolation structure 15K1. In the extension direction of the blocking structure 14C, the disconnection of the light-emitting functional layer 21 at each part can be precisely controlled.

[0211] In some implementations, please refer to Figures 1 to 8 and combined Figure 9 As shown, at least a portion of the isolation structure 15 encloses an isolation opening 15K, and at least a portion of the light-emitting devices 20 are disposed within the corresponding isolation opening 15K.

[0212] For example, at least part of the isolation structure 15 encloses an isolation opening 15K, which is used to accommodate the light-emitting device 20.

[0213] For example, the isolation opening 15K is connected to the corresponding pixel opening 142.

[0214] Optionally, in some embodiments, the two isolation structures 15 disposed on both sides of the light-emitting device 20 are a first isolation structure 15K1 and a second isolation structure 15K2, respectively. A blocking structure 14C is disposed between one of the first isolation structure 15K1 and the second isolation structure 15K2 and the center of the light-emitting device 20, and at least one film layer in the light-emitting functional layer 21 is disconnected at the blocking structure 14C.

[0215] For example, Figures 1 to 9 For example, a blocking structure 14C is provided between the first isolation structure 15K1 and the center (or central region, or light-emitting region) of the light-emitting device 20. The blocking structure 14C has the structure and function described above, and will not be repeated here.

[0216] Optionally, in some embodiments, the plurality of isolation structures 15 further include a third isolation structure 15K3 and a fourth isolation structure 15K4. The third isolation structure 15K3 is connected to one end of the first isolation structure 15K1 and one end of the second isolation structure 15K2; the fourth isolation structure 15K4 is connected to the other end of the first isolation structure 15K1 and the other end of the second isolation structure 15K2; the first isolation structure 15K1, the third isolation structure 15K3, the second isolation structure 15K2 and the fourth isolation structure 15K4 are connected in sequence and arranged around the light-emitting device 20.

[0217] For example, in some implementations, such as Figure 9 As shown, the first isolation structure 15K1, the third isolation structure 15K3, the second isolation structure 15K2 and the fourth isolation structure 15K4 are connected in sequence and arranged around the light-emitting device 20. At this time, the multiple isolation structures 15 form a ring around the light-emitting device 20.

[0218] Alternatively, in some implementations, such as Figure 9 As shown, the first isolation structure 15K1 and the second isolation structure 15K2 are arranged opposite each other in the first direction X, and the third isolation structure 15K3 and the fourth isolation structure 15K4 are arranged opposite each other in the second direction Y. The first direction X and the second direction Y intersect.

[0219] Optionally, in some implementations, the first direction X is perpendicular to the second direction Y.

[0220] Optionally, in some embodiments, the first isolation structure 15K1, the third isolation structure 15K3, the second isolation structure 15K2 and the fourth isolation structure 15K4 are sequentially connected to form a ring structure.

[0221] Optionally, in some embodiments, a blocking structure 14C is provided between one of the third isolation structure 15K3 and the fourth isolation structure 15K4 and the center of the corresponding light-emitting device 20.

[0222] For example, in some embodiments, a blocking structure 14C is provided between one of the third isolation structure 15K3 and the fourth isolation structure 15K4 and the center of the corresponding light-emitting device 20, while no blocking structure 14C is provided between the other of the third isolation structure 15K3 and the center of the corresponding light-emitting device 20. This embodiment is the same as or similar to the first isolation structure 15K1 and the second isolation structure 15K2 in structure and function, and will not be described again here.

[0223] Optionally, in some embodiments, a blocking structure 14C is provided between the third isolation structure 15K3 and the fourth isolation structure 15K4 and the center of the corresponding light-emitting device 20.

[0224] For example, in some embodiments, a blocking structure 14C is provided between the first isolation structure 15K1, the third isolation structure 15K3 and the fourth isolation structure 15K4 and the center of the corresponding light-emitting device 20, while no blocking structure 14C is provided between the second isolation structure 15K2 and the center of the corresponding light-emitting device 20. Both sides of the light-emitting device 20 in the first direction X and one side in the second direction Y can prevent or improve the lateral charge flow in the light-emitting functional part 21, thereby improving the luminous efficiency and the display quality of the display panel.

[0225] Secondly, please refer to Figures 1 to 3 , Figures 4 to 6 ,or Figure 7 and Figure 8This application provides a display panel 100, which includes an array substrate 10, and a plurality of light-emitting devices 20, a plurality of isolation structures 15, and a plurality of blocking structures 14C disposed on the same side of the array substrate 10. The light-emitting device 20 includes a first electrode 131, a light-emitting functional layer 21, and a second electrode 22 sequentially stacked on one side of the array substrate 10. The light-emitting functional layer 21 includes at least one film layer. At least a portion of the isolation structures 15 enclose an isolation opening 15K, and at least a portion of the light-emitting devices 20 are disposed within the corresponding isolation opening 15K. On a plane parallel to the array substrate 10, a blocking structure 14C is disposed between the isolation structure 15 on at least one side of the light-emitting device 20 and the center of the light-emitting device 20. The blocking structure 14C is partially disposed around the center of the light-emitting device 20, and at least one film layer in the light-emitting functional layer 21 is broken at the blocking structure 14C.

[0226] For example, the blocking structure 14C is partially disposed around the center of the light-emitting device 20, that is, there is no blocking structure 14C between the isolation structure 15 on at least one side of the light-emitting device 20 and the center of the light-emitting device 20.

[0227] In this embodiment, a blocking structure 14C is provided between the isolation structure 15 located on one side of the light-emitting device 20 and the center of the light-emitting device 20, and at least one film layer in the light-emitting functional layer 21 is broken at the blocking structure 14C. On the one hand, this makes the broken film layer in the light-emitting functional layer 21 a discontinuous structure at the blocking structure 14C. Even if the light-emitting functional layer 21 partially overlaps the sidewall of the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device, it can avoid or improve the lateral flow of charge in the light-emitting device 20. For example, it can avoid or improve the flow of charge between the light-emitting functional layer 21 and the isolation structure 15, thereby preventing the charge from flowing laterally or escaping in the light-emitting functional layer 21 through the blocking structure 14C on the side of the isolation structure 15 away from the center of the light-emitting device 20, thereby improving the luminous efficiency of the light-emitting device 20 and enhancing the display quality of the display panel. Secondly, no blocking structure 14C is provided between the isolation structure 15 located on one side of the light-emitting device 20 and the center of the light-emitting device 20. The second electrode 22 of the light-emitting device 20 can be connected to the isolation structure 15 on the side without the blocking structure 14C. When the isolation structure 15 is a conductive structure, it is convenient to provide an electrical signal to the second electrode 22 through the isolation structure 15 on the side without the blocking structure 14C.

[0228] In this embodiment, at least a portion of the isolation structure 15 encloses an isolation opening 15K, and at least a portion of the light-emitting devices 20 are disposed within the corresponding isolation opening 15K. This allows at least one film layer in the light-emitting functional layer 21 to be disconnected at the blocking structure 14C on multiple sides of the light-emitting device 20, or / and allows electrical signals to be provided through the isolation structure 15 on multiple sides of the light-emitting device 20 where the blocking structure 14C is not provided. This can simultaneously achieve the balanced effect of preventing the lateral flow of charge in the light-emitting functional layer 21 and improving the uniformity of the electrical signal of the second electrode 22.

[0229] In some embodiments, the plurality of isolation structures 15 forming the isolation opening 15K includes a first isolation structure 15K1 and a second isolation structure 15K2. The first isolation structure 15K1 and the second isolation structure 15K2 are disposed opposite to each other on both sides of the light-emitting device 20. The first isolation structure 15K1 includes a first isolation sidewall 15a, and the second isolation structure 15K2 includes a second isolation sidewall 15b. On a plane parallel to the array substrate 10, the blocking structure 14C is located between the first isolation sidewall 15a and the center of the light-emitting device 20. The second electrode 22 of the light-emitting device 20 is attached to the second isolation sidewall 15b.

The first light-emitting functional part 211 in at least a portion of the light-emitting device 20 is spaced apart from the second isolation sidewall 15b, and the second electrode 22 covers the edge of the first light-emitting functional part 211 away from the first isolation sidewall 15a.

[0233] Optionally, in some embodiments, at least a portion of the first light-emitting functional part 211 in the light-emitting device 20 is attached to the first isolation sidewall 15a.

[0236] Alternatively, in some embodiments, the support portion 152 and the crown portion 153 are integrally formed.

[0237] Alternatively, in some embodiments, the support portion 152 and the crown portion 153 are made of different materials.
