Detailed Implementation

[0091] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0092] In the description of this application, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed when in use. They 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. Therefore, they should not be construed as limitations on this application.

[0093] Increasing the density of light-emitting devices (i.e., pixel density) in display panels is a crucial way to improve display quality. However, current display panels manufactured using Fine Metal Mask (FMM) technology are limited by technological constraints, preventing further increases in the density of light-emitting devices. Through long-term research, the inventors discovered that to address the technical challenge of limiting the density of light-emitting devices, an isolation structure can be incorporated into some display panels. During the full-layer deposition of the light-emitting material layer and electrodes, the material layer and electrodes can be separated at the isolation structure location. Through multiple deposition and etching processes, light-emitting devices of different colors can be formed in different isolation openings. This process is also known as light-emitting device patterning.

[0094] Patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 100935, PCT / CN2024 / 102785, PCT / CN2024 / 099419, PCT / CN2024 / 099072, and CN116685174A describe relevant technical solutions for isolation structures (or partition structures or isolation pillars) and encapsulation layers, the contents of which are incorporated herein by reference.

[0095] In the aforementioned display panel, the connection between the electrodes and the isolation structure directly affects the display effect of the display panel. For example, poor connection between the electrodes and the isolation structure can lead to abnormal display of the light-emitting device, thereby affecting the display effect of the display panel.

[0096] To address the aforementioned problems, the inventors have innovatively designed the following technical solutions, which will be described in detail below with reference to the accompanying drawings. It should be noted that the deficiencies in the existing solutions are the result of the inventors' practical experience and careful research. Therefore, the discovery process of the aforementioned technical problems and the solutions proposed in this embodiment below are contributions made by the inventors to this application during the invention process, and should not be construed as technical content known to those skilled in the art.

[0097] Please refer to Figures 1 and 2. Figure 1 illustrates a schematic diagram of the positional relationship between the isolation structure and the isolation openings in the display panel provided in this embodiment. Figure 2 illustrates a cross-sectional schematic diagram at position AA in Figure 1. In this embodiment, the display panel 1 includes a substrate 11 and an isolation structure 12. The isolation structure 12 is located on the substrate 11 and includes a plurality of isolation openings 1201. The plurality of isolation openings 1201 are arranged into a plurality of isolation opening columns 1211 arranged in a second direction (X direction in the figure). Each isolation opening column 1211 extends along a first direction (Y direction in the figure), wherein the first direction and the second direction intersect.

[0098] The outline of the orthographic projection of the isolation opening 1201 on the substrate 11 includes a first outline 201 extending along a first direction and located on one side of the isolation opening 1201, and a second outline 202 extending along the first direction on the opposite side of the side where the first outline 201 is located. That is, both the first outline 201 and the second outline 202 extend along the first direction and are located on opposite sides of the isolation opening 1201.

[0099] In the same isolation opening column 1211, the first contour lines 201 of different isolation openings 1201 are flush and the second contour lines 202 of different isolation openings 1201 are flush.

[0100] In this embodiment, the display panel 1 further includes a light-emitting device 13 and a packaging unit 141, wherein at least a portion of the light-emitting device 13 is located within the isolation opening 1201, and the packaging unit 141 is used to package the light-emitting device 13 in the isolation opening 1201.

[0101] In the above structure, when the isolation structure 12 is side-etched using an etching solution, when the etching solution overflows from a certain isolation opening 1201, it can be transferred to the adjacent isolation opening 1201. Since the first contour lines 201 of different isolation openings 1201 in the isolation opening row 1211 are flush and the second contour lines 202 of different isolation openings 1201 are flush, the overflowing etching solution is more easily transferred to the adjacent isolation opening 1201 along the first direction. A channel for rapid flow of etching solution can be formed in the first direction (Y direction in the figure). This avoids the problem of etching solution accumulating or accumulating in certain positions, thereby making the side-etching amount of the isolation structure 12 uniform at different positions, ensuring product quality and yield, and improving the display effect of the display panel 1.

[0102] Furthermore, in this embodiment, referring to Figure 1 again, the plurality of isolation openings 1201 are also arranged into a plurality of isolation opening rows 1212 arranged in a first direction (Y direction in the figure), and each isolation opening row 1212 extends along a second direction (X direction in the figure). For example, the first direction and the second direction can be perpendicular to each other, that is, the isolation opening rows 1212 and the isolation opening columns 1211 are perpendicular to each other.

[0103] It should be noted that there is no difference between the isolation opening column 1211 and the isolation opening row 1212. The isolation opening column 1211 and the isolation opening row 1212 simply represent the arrangement of the isolation openings 1201 in different directions, that is, they are used to distinguish the arrangement of the isolation openings 1201 in different directions. For example, in other embodiments, the isolation openings 1201 can also form the isolation opening row 1212 when arranged along the first direction, and the isolation openings 1201 can also form the isolation opening column 1211 when arranged along the second direction.

[0104] Referring again to Figure 1, the outline of the isolation opening 1201 projected onto the substrate 11 includes a third outline 203 extending along the second direction (X direction in the figure) and located on one side of the isolation opening 1201, and a fourth outline 204 extending along the second direction on the opposite side of the side where the third outline 203 is located. That is, both the third outline 203 and the fourth outline 204 extend along the second direction and are located on opposite sides of the isolation opening 1201.

[0105] In the same row of isolation openings 1212, the third contour line 203 of at least some of the isolation openings 1201 is flush with the fourth contour line 204 of at least some of the isolation openings 1201. Optionally, in the same row of isolation openings 1212, the third contour line 203 of all the isolation openings 1201 is flush with the fourth contour line 204 of all the isolation openings 1201.

[0106] When the isolation structure 12 is side-etched using an etching solution, when the etching solution overflows from a certain isolation opening 1201, it can be transferred to adjacent isolation openings 1201. Since the third contour lines 203 and the fourth contour lines 204 of different isolation openings 1201 in the isolation opening row 1212 are flush, the overflowing etching solution is more easily transferred to adjacent isolation openings 1201 along the second direction, forming a fast flow channel for the etching solution in the second direction (X direction in the figure). That is, in this embodiment, a fast flow channel for the etching solution can be formed in the first direction and / or the second direction, which can accelerate the flow speed of the etching solution, prevent the etching solution from accumulating or accumulating at certain locations, so that the isolation structures 12 at different locations are subjected to the etching solution for the same amount of time, and the side-etching amount of the isolation structures 12 at different locations is uniform, ensuring product quality and yield.

[0107] In this embodiment, "alignment of different contour lines" means that the alignment error between different contour lines is within the range allowed by the process accuracy. That is, as long as the error between different contour lines is within the range allowed by the process accuracy, it can be determined that the different contour lines are aligned.

[0108] Referring to Figures 1 and 3, in the same isolation opening column 1211, if the distance d1 between a point on the first contour line 201 of an isolation opening 1201 and a point on the first contour line 201 of an adjacent isolation opening 1201 in the second direction (X direction in the figure) is less than or equal to 3 μm, it can be considered that the first contour lines 201 of different isolation openings 1201 in the same isolation opening column 1211 are flush. For example, the distance d1 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm or 3 μm, etc. If the distance d2 between a point on the second contour line 202 of the isolation opening 1201 and a point on the second contour line 202 of an adjacent isolation opening 1201 in the second direction is less than or equal to 3 μm, then the second contour lines 202 of different isolation openings 1201 in the same isolation opening column 1211 are considered to be flush. For example, the distance d2 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm or 3 μm, etc.

[0109] Please refer to Figures 1 and 3 again. In the same row of isolation openings 1212, if the distance d3 between a point on the third contour line 203 of an isolation opening 1201 and a point on the third contour line 203 of at least partially adjacent isolation openings 1201 in the first direction (Y direction in the figure) is less than or equal to 3 μm, it can be considered that the third contour lines 203 of at least partially isolation openings 1201 in the same row of isolation openings 1212 are flush. For example, the distance d3 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm or 3 μm, etc. If the distance between a point on the fourth contour line 204 of the isolation opening 1201 and a point on the fourth contour line 204 of at least partially adjacent isolation openings 1201 in the first direction is less than or equal to 3 μm, it can be considered that the fourth contour lines 204 of at least some isolation openings 1201 in the same isolation opening row 1212 are flush. For example, the distance d4 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm or 3 μm, etc.

[0110] Referring to Figure 4a, in one possible implementation of this embodiment, the isolation opening column 1211 includes adjacent first isolation opening columns 12111 and second isolation opening columns 12112, and the isolation opening 1201 includes a first isolation opening 1201a, a second isolation opening 1201b, and a third isolation opening 1201c. Multiple first isolation openings 1201a are distributed along a first direction (Y direction in the figure) to form the first isolation opening column 12111. The second isolation openings 1201b and the third isolation opening 1201c are alternately arranged in the first direction (Y direction in the figure) to form the second isolation opening column 12112. The first isolation openings 1201a, second isolation openings 1201b, and third isolation openings 1201c form isolation opening units 124, and multiple isolation opening units 124 are arranged in a second direction (X direction in the figure) to form isolation opening rows 1212.

[0111] In the first isolation opening row 12111, the first contour lines 201 of different first isolation openings 1201a are flush, and the second contour lines 202 of different first isolation openings 1201a are flush.

[0112] In the second isolation opening row 12112, the first outline 201 of the second isolation opening 1201b and the first outline 201 of the third isolation opening 1201c are flush, and the second outline 202 of the second isolation opening 1201b and the second outline 202 of the third isolation opening 1201c are flush.

[0113] Optionally, in the same row of isolation openings 1212, the third contour line 203 of the first isolation opening 1201a, the third contour line 203 of the second isolation opening 1201b, and the third contour line 203 of the third isolation opening 1201c are flush, and the fourth contour line 204 of the first isolation opening 1201a, the fourth contour line 204 of the second isolation opening 1201b, and the fourth contour line 204 of the third isolation opening 1201c are flush.

[0114] Referring to Figure 4b, in another possible implementation of this embodiment, the isolation opening column 1211 includes adjacent first isolation opening columns 12111, second isolation opening columns 12112, and third isolation opening columns 12113, and the isolation opening 1201 includes first isolation opening 1201a, second isolation opening 1201b, and third isolation opening 1201c. A plurality of first isolation openings 1201a are distributed along a first direction (Y direction in the figure) to form the first isolation opening column 12111, a plurality of second isolation openings 1201b are distributed along the first direction to form the second isolation opening column 12112, and a plurality of third isolation openings 1201c are distributed along the first direction to form the third isolation opening column 12113.

[0115] In this embodiment, the first isolation opening 1201a, the second isolation opening 1201b and the third isolation opening 1201c form an isolation opening unit 124, and the plurality of isolation opening units 124 are arranged in the second direction (X direction in the figure) to form an isolation opening row 1212.

[0116] In the same first isolation opening row 12111, the first contour lines 201 of different first isolation openings 1201a are flush, and the second contour lines 202 of different first isolation openings 1201a are also flush.

[0117] In the same second isolation opening row 12112, the first contour lines 201 of different second isolation openings 1201b are flush, and the second contour lines 202 of different second isolation openings 1201b are also flush.

[0118] In the same third isolation opening column 12113, the first contour lines 201 of different third isolation openings 1201c are flush, and the second contour lines 202 of different third isolation openings 1201c are also flush.

[0119] In the same row of isolation openings 1212, the third contour line 203 of the first isolation opening 1201a, the third contour line 203 of the second isolation opening 1201b, and the third contour line 203 of the third isolation opening 1201c are flush, and the fourth contour line 204 of the first isolation opening 1201a, the fourth contour line 204 of the second isolation opening 1201b, and the fourth contour line 204 of the third isolation opening 1201c are flush.

[0120] Referring to Figure 4c, in another possible implementation of this embodiment, the isolation opening column 1211 includes adjacent first isolation opening columns 12111 and second isolation opening columns 12112, and the isolation opening 1201 includes a first isolation opening 1201a, a second isolation opening 1201b, and a third isolation opening 1201c. The first isolation openings 1201a and the second isolation openings 1201b are alternately arranged in a first direction (Y direction in the figure) to form the first isolation opening column 12111. A plurality of third isolation openings 1201c are arranged in the first direction (Y direction in the figure) to form the second isolation opening column 12112.

[0121] In this embodiment, the first isolation opening 1201a, the second isolation opening 1201b and the third isolation opening 1201c form an isolation opening unit 124, and the plurality of isolation opening units 124 are arranged in the second direction to form an isolation opening row 1211.

[0122] In the first isolation opening row 12111, the first outline 201 of the first isolation opening 1201a and the first outline 201 of the second isolation opening 1201b are flush, and the second outline 202 of the first isolation opening 1201a and the second outline 202 of the second isolation opening 1201b are flush.

[0123] In the second isolation opening row 12112, the first outline 201 of the different third isolation openings 1201c are flush, and the second outline 202 of the different third isolation openings 1201c are flush.

[0124] In this embodiment, within the same row of isolation openings 1212, the third contour line 203 of the first isolation opening 1201a and the third contour line 203 of the third isolation opening 1201c are flush, and the fourth contour line 204 of the second isolation opening 1201b is flush with the fourth contour line 204 of the third isolation opening 1201c. That is, in the arrangement shown in FIG. 4c, the first isolation opening 1201a has a third contour line 203 that is flush with the third contour line 203 of the adjacent third isolation opening 1201c, and the second isolation opening 1201b has a fourth contour line 204 that is flush with the fourth contour line 204 of the adjacent third isolation opening 1201c.

[0125] In this embodiment, in the same isolation opening column 1211, the shapes and areas of the different isolation openings 1201 projected onto the substrate 11 are the same. For example, in the same isolation opening column 1211, the projected shapes of the different isolation openings 1201 onto the substrate 11 can be rectangles with the same area.

[0126] The isolation openings 1201 located in different isolation opening rows 1211 have the same or similar orthographic projection shapes on the substrate 11, and the orthographic projection areas of the isolation openings 1201 located in different isolation opening rows 1211 on the substrate 11 may be the same or different. Exemplarily, in some embodiments, the orthographic projections of the isolation openings 1201 located in different isolation opening rows 1211 on the substrate 11 may have the same shape and the same orthographic projection area; in other embodiments, the orthographic projections of the isolation openings 1201 located in different isolation opening rows 1211 on the substrate 11 may have similar shapes, but different orthographic projection areas.

[0127] Referring to Figure 5a, the outline of the orthographic projection of the packaging unit 141 on the substrate 11 includes a fifth outline 205 extending along the first direction (Y direction in the figure) and located on one side of the packaging unit 141, and a sixth outline 206 extending along the first direction on the opposite side of the side where the fifth outline 205 is located. That is, the fifth outline 205 and the sixth outline 206 both extend along the second direction and are located on opposite sides of the packaging unit 141.

[0128] The fifth contour line 205 for encapsulating different packaging units 141 of light-emitting devices 13 in different isolation openings 1201 in the same isolation opening column 1211 is flush with the sixth contour line 206 for encapsulating different packaging units 141 of light-emitting devices 13 in different isolation openings 1201 in the same isolation opening column 1211.

[0129] The above structure allows different packaging units 141 to have aligned edges in the first direction, which makes the structure of different packaging units 141 in the first direction more balanced. When subjected to external force, different packaging units 141 can distribute the load evenly, avoiding damage to the packaging units 141. This helps to improve the overall structural stability of the packaging units 141 and ensure the packaging effectiveness of the packaging units.

[0130] Further, referring to Figures 5a, 5b and 5c, the outline of the orthographic projection of the packaging unit 141 on the substrate 11 includes a seventh outline 207 extending along the second direction (X direction in the figure) and located on one side of the packaging unit, and an eighth outline 208 extending along the second direction on the opposite side of the seventh outline 207. That is, both the seventh outline 207 and the eighth outline 208 extend along the second direction and are located on opposite sides of the packaging unit 141.

[0131] The packaging unit 141 includes a first packaging unit 141a, a second packaging unit 141b, and a third packaging unit 141c. The first packaging unit 141a is used to package the light-emitting device 13 in the first isolation opening 1201a, the second packaging unit 141b is used to package the light-emitting device 13 in the second isolation opening 1201b, and the third packaging unit 141c is used to package the light-emitting device 13 in the third isolation opening 1201c.

[0132] In this embodiment, two adjacent encapsulation units 141 used to encapsulate the light-emitting device 13 are disconnected on the side of the isolation structure 12 away from the substrate 11. That is, two adjacent encapsulation units 141 used to encapsulate light-emitting devices 13 with different or the same light-emitting colors are both disconnected on the side of the isolation structure 12 away from the substrate 11. This ensures that no light-emitting material layer remains on the isolation structure 12 between adjacent isolation openings 1201, thus avoiding the problem of different colors in the appearance of the display panel.

[0133] In one possible implementation, as shown in Figures 5a and 5b, the seventh contour line 207 of the encapsulation unit 141 for encapsulating the light-emitting devices 13 in different isolation openings 1201 in the same isolation opening row 1211 is flush with the eighth contour line 208 of the encapsulation unit 141 for encapsulating the light-emitting devices 13 in different isolation openings 1201 in the same isolation opening row 1211 is flush with the eighth contour line 208.

[0134] In another possible implementation, as shown in FIG5c, the seventh contour line 207 of the first packaging unit 141a and the third packaging unit 141c, which are used to encapsulate the light-emitting devices 13 in different isolation openings 1201 within the same row of isolation openings 1211, is flush with the eighth contour line 208 of the second packaging unit 141b and the third packaging unit 141c, which are used to encapsulate the light-emitting devices 13 in different isolation openings 1201 within the same row of isolation openings 1211. That is, in the arrangement shown in FIG5c, the first packaging unit 141a has a seventh contour line 207 that is flush with the seventh contour line 207 of the adjacent third packaging unit 141c, and the second packaging unit 141b has an eighth contour line 208 that is flush with the eighth contour line 208 of the adjacent third packaging unit 141c.

[0135] The above structure also allows different packaging units 141 to have aligned edges in the second direction, which makes the structure of different packaging units 141 in the second direction more balanced. When subjected to external force, different packaging units 141 can distribute the load evenly, avoiding damage to the packaging units 141. This helps to improve the overall structural stability of the packaging units 141 and ensure the packaging effectiveness of the packaging units.

[0136] In this embodiment, referring to Figures 5a and 6, if the distance d5 of the fifth contour lines 205 of adjacent packaging units 141 used to encapsulate the light-emitting devices 13 in different isolation openings 1201 of the same isolation opening column 1211 is less than or equal to 3μm, it can be determined that the fifth contour lines 205 of different packaging units 141 used to encapsulate the light-emitting devices 13 in different isolation openings 1201 of the same isolation opening column 1211 are aligned. For example, the distance d5 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc. If the distance d6 of the sixth contour line 206 of adjacent packaging units 141 used to encapsulate light-emitting devices 13 in different isolation openings 1201 of the same isolation opening column 1211 in the second direction is less than or equal to 3μm, it can be determined that the sixth contour line 206 of different packaging units 141 used to encapsulate light-emitting devices 13 in different isolation openings 1201 of the same isolation opening column 1211 are aligned. For example, the distance d6 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc.

[0137] In one embodiment, referring to Figures 5a, 5b, and 6, if the distance d7 of the seventh contour line 207 of adjacent packaging units 141 for encapsulating light-emitting devices 13 in different isolation openings 1201 within the same isolation opening row 1212 is less than or equal to 3 μm, it can be considered that the seventh contour line 207 of the packaging units 141 for encapsulating light-emitting devices 13 in different isolation openings 1201 within the same isolation opening row 1212 is aligned. For example, the distance d7 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm, or 3 μm, etc. If the distance d8 between the eighth contour lines 208 of adjacent packaging units 141 used to encapsulate light-emitting devices 13 in different isolation openings 1201 within the same isolation opening row 1211 in the first direction is less than or equal to 3 μm, it can be determined that the eighth contour lines 208 of the packaging units 141 used to encapsulate light-emitting devices 13 in different isolation openings 1201 within the same isolation opening row 1211 are aligned. For example, the distance d8 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm, or 3 μm, etc.

[0138] In another embodiment, referring to Figures 5c and 6, the outlines of some packaging units 141 used to encapsulate light-emitting devices 13 in different isolation openings 1201 within the same row of isolation openings 1212 are aligned. If the distance d7 of the seventh outlines 207 of the first packaging unit 141a and the third packaging unit 141c used to encapsulate light-emitting devices 13 in different isolation openings 1201 within the same row of isolation openings 1212 in the first direction is less than or equal to 3 μm, it can be considered that the seventh outlines 207 of the first packaging unit 141a and the third packaging unit 141c used to encapsulate light-emitting devices 13 in different isolation openings 1201 within the same row of isolation openings 1212 are aligned. Exemplarily, the distance d7 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm, or 3 μm, etc. If the distance d8 of the eighth contour line 208 of the second packaging unit 141b and the third packaging unit 141c used to encapsulate the light-emitting devices 13 in different isolation openings 1201 in the same isolation opening row 1212 is less than or equal to 3μm, it can be considered that the eighth contour line 208 of the second packaging unit 141b and the third packaging unit 141c used to encapsulate the light-emitting devices 13 in different isolation openings 1201 in the same isolation opening row 1212 is aligned. For example, the distance d8 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc.

[0139] Further, referring to FIG7, in the direction away from the substrate 11, the light-emitting device 13 includes a first electrode 131, a light-emitting material layer 132 and a second electrode 133 stacked together. The first electrode 131 is located on the side of the isolation structure 12 facing the substrate 11, and the second electrode 133 overlaps with the isolation structure 12.

[0140] Optionally, the light-emitting device 13 includes a first light-emitting device 13a, a second light-emitting device 13b, and a third light-emitting device 13c of different light-emitting colors, wherein at least a portion of the first light-emitting device 13a is located within the first isolation opening 1201a, at least a portion of the second light-emitting device 13b is located within the second isolation opening 1201b, and at least a portion of the third light-emitting device 13c is located within the third isolation opening 1201c.

[0141] Referring again to Figure 7, in the direction away from the substrate 11, the isolation structure 12 includes a first isolation portion 121 and a second isolation portion 122 stacked together, with the second electrode 133 overlapping the second isolation portion 122. The orthographic projection of the first isolation portion 121 on the substrate 11 lies within the orthographic projection of the second isolation portion 122 on the substrate 11, that is, the second isolation portion 122 extends relative to the first isolation portion 121, and the outline of the orthographic projection of the isolation opening 1201 on the substrate 11 is formed by the orthographic projection of the edge of the second isolation portion 122 toward the isolation opening 1201 on the substrate 11.

[0142] In this embodiment, referring to FIG8a, the orthographic projection of the first electrode 131 on the substrate 11 at least partially overlaps with the orthographic projection of the isolation opening 1201 on the substrate 11. A plurality of first electrodes 131 are arranged into a plurality of first electrode rows 1311 arranged in a second direction (X direction in the figure). The outline of the orthographic projection of the first electrode 131 on the substrate 11 includes a ninth outline 209 extending along the first direction and located on one side of the first electrode 131, and a tenth outline 210 extending along the first direction on the opposite side of the ninth outline 209.

[0143] In the same first electrode array 1311, the ninth contour line 209 of different first electrodes 131 are flush with each other and the tenth contour line 210 of different first electrodes 131 are flush with each other.

[0144] In this embodiment, the first electrode 131 is generally formed by wet etching using a three-layer conductive structure of ITO / Ag / ITO. In the same first electrode row 1311, the ninth contour lines 209 of different first electrodes 131 are flush and the tenth contour lines 210 of different first electrodes 131 are flush, which can form a channel for rapid flow of etching solution in the first direction (Y direction in the figure). This can ensure that the Ag in the middle is not over-etched, thus affecting the conductivity of the first electrode 131 and ensuring that the first electrode 131 has good conductivity.

[0145] Furthermore, the plurality of first electrodes 131 are also arranged into a plurality of first electrode rows 1312 arranged in a first direction (Y direction in the figure), wherein the first direction and the second direction intersect, and exemplarily, the first direction and the second direction may be perpendicular to each other.

[0146] It should be noted that there is no difference between the first electrode column 1311 and the first electrode row 1312. The first electrode column 1311 and the first electrode row 1312 simply represent the arrangement of the first electrodes in different directions, that is, they are used to distinguish the arrangement of the first electrodes in different directions. For example, in other embodiments, the first electrode 131 can also form the first electrode row 1312 by arranging the first electrode 131 along the first direction, and the first electrode 131 can also form the first electrode column 1311 by arranging the first electrode 131 along the second direction.

[0147] Referring to Figures 8a, 8b and 8c, the outline of the first electrode 131 projected onto the substrate 11 includes an eleventh outline 211 extending along the second direction (Y direction in the figure) and located on one side of the first electrode 131, and a twelfth outline 212 located on the opposite side of the eleventh outline 211 along the second direction. That is, the eleventh outline 211 and the twelfth outline 212 both extend along the second direction and are located on opposite sides of the first electrode 131. In this embodiment, the first electrode 131 includes a first sub-electrode 131a, a second sub-electrode 131b, and a third sub-electrode 131c. The orthographic projection of the first sub-electrode 131a on the substrate 11 at least partially overlaps with the orthographic projection of the first isolation opening 1201a on the substrate 11. The orthographic projection of the second sub-electrode 131b on the substrate 11 at least partially overlaps with the orthographic projection of the second isolation opening 1201b on the substrate 11. The orthographic projection of the third sub-electrode 131c on the substrate 11 at least partially overlaps with the orthographic projection of the third isolation opening 1201c on the substrate 11.

[0148] In one embodiment of this example, referring to Figures 8a and 8b, in the same first electrode row 1312, the eleventh contour lines 210 of different first electrodes 131 are flush, and the twelfth contour lines 212 of different first electrodes 131 are also flush. That is, in the same first electrode row 1312, the eleventh contour lines 211 of the first sub-electrode 131a, the second sub-electrode 131b, and the third sub-electrode 131c are aligned, and the twelfth contour lines 212 of the first sub-electrode 131a, the second sub-electrode 131b, and the third sub-electrode 131c are also aligned.

[0149] In another embodiment of this invention, referring to FIG8c, in the same first electrode row 1312, the eleventh contour line 211 of the first sub-electrode 131a and the eleventh contour line 211 of the third sub-electrode 131c are flush, and the twelfth contour line 212 of the second sub-electrode 131b and the twelfth contour line 212 of the third sub-electrode 131c are flush. That is, in the arrangement shown in FIG8c, the first sub-electrode 131a has an eleventh contour line 211 that is flush with the eleventh contour line 211 of the adjacent third sub-electrode 131c, and the second sub-electrode 131b has a twelfth contour line 212 that is flush with the twelfth contour line 212 of the adjacent third sub-electrode 131c.

[0150] The above design can form rapid flow channels for the etching solution in both the first direction (Y direction in the figure) and the second direction (X direction in the figure) during the wet etching patterning process of the first electrode 131. This can ensure that the etching time of the etching solution at different positions is basically the same, ensuring that each side of the first electrode can be etched uniformly, and that the Ag layer in the middle will not be over-etched, thus ensuring that the first electrode 131 has good conductivity.

[0151] In this embodiment, referring to Figures 8a and 9, in the same first electrode array 1311, if the distance d9 between a point on the ninth contour line 209 of the first electrode 131 and a point on the ninth contour line 209 of the adjacent first electrode 131 in the second direction (Y direction in the figure) is less than or equal to 3μm, it can be determined that the ninth contour lines 209 of different first electrodes 131 are aligned. For example, the distance d9 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc. In the same first electrode array 1311, if the distance d10 between a point on the tenth contour line 210 of the first electrode 131 and a point on the tenth contour line 210 of the adjacent first electrode 131 in the second direction is less than or equal to 3 μm, the tenth contour lines 210 of different first electrodes 131 can be considered aligned. For example, the distance d10 includes 0 μm, 0.5 μm, 1 μm, 1.5 μm, 2.0 μm, 2.5 μm or 3 μm, etc.

[0152] In one possible implementation of this embodiment, referring to Figures 8a, 8b, and 9, in the same first electrode row 1312, if the distance d11 between a point on the eleventh contour line 210 of the first electrode 131 and a point on the eleventh contour line 211 of the adjacent first electrode 131 in the first direction (X direction in the figure) is less than or equal to 3μm, it can be determined that the eleventh contour lines 210 of different first electrodes 131 in the same first electrode row 1311 are flush. For example, the distance d11 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm, or 3μm, etc. In the same first electrode row 1311, if the distance d12 between a point on the twelfth contour line 212 of the first electrode 131 and a point on the twelfth contour line 212 of the adjacent isolation opening 1201 in the first direction is less than or equal to 3μm, it can be determined that the twelfth contour lines 212 of different first electrodes 131 in the same first electrode row 1311 are flush. For example, the distance d12 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc.

[0153] In another possible implementation of this embodiment, referring to Figures 8c and 9, in the same first electrode row 1312, the distance d11 between a point on the eleventh contour line 211 of the first sub-electrode 131a and a point on the eleventh contour line 211 of the adjacent third sub-electrode 131c in the first direction is less than or equal to 3μm. That is, it can be considered that in the same first electrode row 1312, the eleventh contour lines 211 of some first electrodes 131 are flush. For example, the distance d11 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc. In the same first electrode row 1312, the distance d12 between a point on the twelfth contour line 212 of the second sub-electrode 131b and a point on the twelfth contour line 212 of the adjacent third sub-electrode 131c in the first direction is less than or equal to 3μm. That is, it can be considered that in the same first electrode row 1312, the twelfth contour lines 212 of some first electrodes 131 are flush. For example, the distance d12 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc.

[0154] Referring again to Figure 7, in this embodiment, the display panel 1 further includes a pixel defining layer 15 located on one side of the substrate 11, wherein the isolation structure 12 is located on the side of the pixel defining layer 15 away from the substrate 11. The first electrode 131 is located on the side of the pixel defining layer 15 facing the substrate 11. The pixel defining layer 15 is provided with a plurality of pixel openings 1501, which communicate with the isolation openings 1201. The pixel openings 1501 expose at least part of the first electrode 131, wherein the orthographic projection of the pixel openings 1501 on the substrate 11 is located within the orthographic projection of the isolation openings 1201 on the substrate 11.

[0155] In this embodiment, referring to FIG10, a plurality of pixel openings 1501 are arranged into a plurality of pixel opening rows 1512 arranged in a first direction (Y direction in the figure). The outline of the orthogonal projection of the pixel openings 1501 on the substrate 11 includes a thirteenth outline 213 extending along the second direction and located on one side of the pixel opening 1501 and a fourteenth outline 214 extending along the second direction on the opposite side of the side where the thirteenth outline 213 is located. That is, the thirteenth outline 213 and the fourteenth outline 214 both extend along the second direction and are located on opposite sides of the isolation opening 1401.

[0156] In the same pixel opening row 1512, at least some of the pixel openings 1501 have their thirteenth contour line 213 flush with each other and at least some of the pixel openings 1501 have their fourteenth contour line 214 flush with each other.

[0157] Furthermore, the multiple pixel openings 1501 are also arranged into multiple pixel opening columns 1511 arranged in the second direction (X direction in the figure), wherein the first direction and the second direction intersect, and exemplarily, the first direction and the second direction may be perpendicular to each other.

[0158] It should be noted that there is no difference between pixel aperture column 1511 and pixel aperture row 1512. Pixel aperture column 1511 and pixel aperture row 1512 simply represent the arrangement of the first electrode in different directions, that is, they are used to distinguish the arrangement of the first electrode in different directions. For example, in other embodiments, pixel aperture 1501 can also form pixel aperture row 1512 when arranged along the first direction, and pixel aperture 1501 can also form pixel aperture column 1511 when arranged along the second direction.

[0159] The outline of the orthographic projection of the pixel opening 1501 on the substrate 11 includes a fifteenth outline 215 extending along the first direction and located on one side of the pixel opening 1501, and a sixteenth outline 216 located on the opposite side of the side where the fifteenth outline 215 is located. That is, the fifteenth outline 215 and the sixteenth outline 216 both extend along the first direction and are located on opposite sides of the pixel opening 1501.

[0160] The pixel opening 1501 includes a first pixel opening 1501a, a second pixel opening 1501b, and a third pixel opening 1501c. The first pixel opening 1501a is connected to the first isolation opening 1201a, the second pixel opening 1501b is connected to the second isolation opening 1201b, and the third pixel opening 1501c is connected to the third isolation opening 1201c.

[0161] Referring to Figure 10, in the same pixel opening column 1511, the fifteenth contour line 215 of the same pixel opening 1501 is flush, and the sixteenth contour line 216 of the same pixel opening 1501 is flush; at least one of the fifteenth contour line 215 and the sixteenth contour line 216 of different pixel openings 1501 is not flush.

[0162] Optionally, in this embodiment, the projected areas of the first isolation opening 1201a, the second isolation opening 1201b, and the third isolation opening 1201c on the substrate 11 are different. Correspondingly, the projected areas of the first pixel opening 1501a, the second pixel opening 1501b, and the third pixel opening 1501c on the substrate 11 are also different. For example, the projected area of ​​the pixel opening 1501 on the substrate 11 is positively correlated with the projected area of ​​the corresponding isolation opening 1201 on the substrate 11; that is, the larger the projected area of ​​the pixel opening 1501 on the substrate 11, the larger the projected area of ​​the corresponding isolation opening 1201 on the substrate 11.

[0163] In this embodiment, referring to Figures 10 and 11, in the same pixel opening row 1512, the distance d13 of the thirteenth contour line 213 of at least some adjacent pixel openings 1501 in the second direction (Y direction in the figure) is less than or equal to 3μm. Thus, it can be determined that in the same pixel opening row 1512, the thirteenth contour line 213 of at least some pixel openings 1501 are aligned. For example, the distance d13 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc. In the same pixel opening row 1512, the distance d14 of the fourteenth contour line 214 of at least some adjacent pixel openings 1501 in the second direction is less than or equal to 3μm. Thus, it can be considered that the fourteenth contour line 214 of at least some pixel openings 1501 in the same pixel opening row 1512 is aligned. For example, the distance d14 includes 0μm, 0.5μm, 1μm, 1.5μm, 2.0μm, 2.5μm or 3μm, etc.

[0164] In the same pixel aperture column 1511, the distance d15 of the fifteenth contour line 215 of the same pixel aperture 1501 in the second direction is less than or equal to 3μm, and the distance d16 of the sixteenth contour line 216 of the same pixel aperture 1501 in the second direction is less than or equal to 3μm.

[0165] In the same pixel aperture column 1511, the distance between the fifteenth contour line 215 of different pixel apertures 1501 in the second direction is greater than 3μm, and / or the distance between the sixteenth contour line 215 of different pixel apertures 1501 in the second direction is greater than 3μm.

[0166] This design allows for flexible control of the area of ​​each pixel opening based on the luminous efficiency of each light-emitting device to meet the display effect of the display panel.

[0167] Furthermore, in this embodiment, referring to FIG12, the display panel 1 further includes a first encapsulation layer 142, which is located on the side of the encapsulation unit 141 away from the substrate 11, and the first encapsulation layer 142 at least covers the encapsulation unit 141. The first encapsulation layer 142 includes a flat surface on the side away from the substrate 11.

[0168] Furthermore, referring again to FIG12, the display panel 1 also includes a second encapsulation layer 143, which is located on the side of the first encapsulation layer 142 away from the substrate 11.

[0169] Optionally, the encapsulation unit 141 and the second encapsulation layer 143 are inorganic encapsulation layers, and the first encapsulation layer 142 is an organic encapsulation layer. For example, the encapsulation unit 141 and the second encapsulation layer 143 can be formed by chemical vapor deposition (CVD), and the first encapsulation layer 142 can be formed by inkjet printing (IJP).

[0170] It is understood that the display panel 1 may also include a touch function layer, an optical adhesive layer, a polarizer and a cover plate, etc., which are stacked sequentially on the side of the second encapsulation layer 143 away from the substrate 11. The above-mentioned film layers are conventional film layers of the display panel, and will not be described in detail here.

[0171] Based on the same inventive concept, embodiments of this application also provide an electronic device, which includes the display panel provided in this application. The electronic device may include smartphones, tablets, in-vehicle display devices, smart wearable devices, televisions, laptops, and other devices with display functions.

[0172] This application provides a display panel and an electronic device. In the display panel, an isolation structure is located on a substrate. The isolation structure includes multiple isolation openings arranged in multiple rows of isolation openings in a second direction. The outline of the orthographic projection of the isolation openings on the substrate includes a first outline and a second outline extending along a first direction and located on opposite sides of the isolation openings. In the same row of isolation openings, the first outlines and second outlines of different isolation openings are flush. This design allows for the formation of a rapid flow channel for the etching solution in the first direction when the isolation structure is side-etched with an etching solution. The etching solution will not accumulate or pool at certain locations, thus ensuring uniform side-etching amount at different locations of the isolation structure, thereby guaranteeing product quality and yield, and improving the display effect of the display panel.

[0173] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
