[0168] 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.

[0169] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0172] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0173] Increasing the density of light-emitting units (i.e., pixel density) in a display panel is a crucial way to improve display quality. However, current display panels manufactured using Fine Metal Mask (FMM) technology are limited by technological constraints that prevent further increases in light-emitting unit density. Through long-term research, the inventors discovered that to address this technical challenge, some display panels incorporate isolation structures. During the full-layer deposition of the light-emitting functional layer and the second electrode, the light-emitting functional layer and the second electrode can be disconnected at the isolation structure. Through multiple deposition and etching processes (i.e., light-emitting unit patterning), light-emitting units of different colors can be formed within different isolation openings.

[0174] Among them, patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, PCT / CN2024 / 099072, CN117979755A, and CN117998900A are included. CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, and CN117500332A record relevant technical solutions for isolation structures (or partition structures or isolation columns), the contents of which are incorporated herein by reference.

[0175] The display panel in the related technology includes a substrate, an insulating layer located on one side of the substrate, an isolation structure located on the side of the insulating layer away from the substrate, and a light-emitting unit located in the isolation opening formed by the isolation structure. The first electrode of the light-emitting unit is electrically connected to the pixel driving circuit in the display panel through a via. The isolation structure has a groove recessed towards the substrate on the side away from the substrate corresponding to the position of the via. When the display panel is off, the groove position of the isolation structure will reflect light, which will cause the display panel to have uneven display when the screen is off.

[0176] To address the aforementioned technical 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.

[0177] Please see Figure 1 and Figure 3 This embodiment provides a display panel, which includes a substrate 1, a driving circuit layer 2, an insulating layer 3, an isolation structure 10, and multiple pixel groups 20.

[0178] The driving circuit layer 2 is located on the substrate 1, and the insulating layer 3 is located on the side of the driving circuit layer 2 away from the substrate 1. Along the thickness direction Z of the substrate 1, the insulating layer 3 is provided with a plurality of vias 31 penetrating the insulating layer 3.

[0179] The isolation structure 10 is located on the side of the insulating layer 3 away from the substrate 1, and the isolation structure 10 encloses and forms the isolation opening 9.

[0180] Each pixel group 20 includes at least two light-emitting units 7, at least a portion of which is located within an isolation opening 9. Each light-emitting unit 7 includes a first electrode 4, which is electrically connected to the driving circuit layer 2 via a via 31. In any two pixel groups 20, the arrangement of the vias 31 corresponding to the multiple light-emitting units 7 in one pixel group 20 is the same as the arrangement of the vias 31 corresponding to the multiple light-emitting units 7 in the other pixel group 20.

[0181] For example, in any two of the at least two first pixel groups 20A, the arrangement of the plurality of vias 31 corresponding to the plurality of light-emitting units 7 in one first pixel group 20A is the same as the arrangement of the plurality of vias 31 corresponding to the plurality of light-emitting units 7 in the other first pixel group 20A. Similarly, in any two of the at least two second pixel groups 20B, the arrangement of the plurality of vias 31 corresponding to the plurality of light-emitting units 7 in one second pixel group 20B is the same as the arrangement of the plurality of vias 31 corresponding to the plurality of light-emitting units 7 in the other second pixel group 20B.

[0182] At least two light-emitting units 7 form a pixel group 20, for example Figure 1 Four light-emitting units 7 form a pixel group 20. In any two pixel groups 20, the arrangement of multiple vias 31 corresponding to multiple light-emitting units 7 in one pixel group 20 is the same as the arrangement of multiple vias 31 corresponding to multiple light-emitting units 7 in another pixel group 20. In this way, the arrangement of vias 31 can be more uniform, more regular or regular.

[0183] The isolation structure 10 forms a recessed groove 11 in the direction of the substrate 1 at the position of the via 31. Since the via 31 is arranged more evenly and regularly, the groove 11 on the side of the isolation structure 10 away from the substrate 1 is arranged more evenly and regularly. When the display panel is off, the reflection of the groove 11 on the side of the isolation structure 10 away from the substrate 1 is more even and regular, thereby improving the display uniformity of the display panel when it is off.

[0184] Based on the above design, this embodiment improves the uniformity of the via arrangement by setting the arrangement of the multiple vias 31 corresponding to the multiple light-emitting units 7 in one pixel group 20 to be the same as the arrangement of the multiple vias 31 corresponding to the multiple light-emitting units 7 in the other pixel group 20. This improves the display uniformity of the display panel when the screen is off. The multiple pixel groups 20 can be arranged in an array, for example, multiple pixel groups 20 can be arranged along a first direction, multiple pixel groups 20 can be arranged along a second direction, and the first and second directions intersect, for example, perpendicularly.

[0185] For some possible implementations, please refer to Figure 4a The lines connecting the centers of the vias 31 corresponding to each light-emitting unit 7 in the same pixel group on the substrate 1 form a virtual polygon.

[0186] Optionally, the lines connecting the centers of the vias 31 corresponding to each light-emitting unit 7 in the same pixel group on the substrate 1 form a virtual quadrilateral.

[0187] Optionally, the orthogonal projection of the via 31 on the substrate 1 is located outside the orthogonal projection of the light-emitting area of ​​the light-emitting unit 7 on the substrate 1.

[0188] Optionally, the orthographic projection of the via 31 on the substrate 1 lies within the orthographic projection of the isolation structure 10 on the substrate 1.

[0189] Preferably, the driving circuit layer 2 includes a pixel driving circuit, which is electrically connected to the first electrode 4 through a via 31.

[0190] In this way, the arrangement of the orthographic projection of the vias 31 on the substrate 1 can be more uniform, thereby further improving the display uniformity of the display panel when the screen is off.

[0191] In some possible implementations, please refer again. Figure 3 The display panel also includes a pixel defining layer 8. For example, the pixel defining layer 8 is located between the isolation structure 10 and the first electrode 4, or the pixel defining layer 8 is provided with a clearance opening, and the isolation structure is located at the clearance opening. The pixel defining layer 8 is provided with a pixel opening 81, which exposes a portion of the first electrode 4. The light-emitting unit 7 also includes a light-emitting part 5 and a second electrode 6 located on the side of the first electrode 4 away from the substrate 1 and stacked sequentially in the direction away from the substrate 1.

[0192] The isolation structure 10 allows the display panel to form film layers of different colors of light-emitting units 7 in different isolation openings 9 without the need for a fine mask. When forming the light-emitting material layer, the isolation structure 10 separates the light-emitting material layer into multiple spaced-apart light-emitting portions 5. When forming the second electrode material layer, the isolation structure 10 separates the second electrode material layer into multiple spaced-apart second electrodes 6. The isolation structure 10 includes a conductive material, and the second electrodes 6 are electrically connected to the isolation structure 10. A first electrode 4, a light-emitting portion 5, and a second electrode 6 form a light-emitting unit 7. The first electrode 4 can be an anode, and the second electrode 6 can be a cathode.

[0193] In this way, different light-emitting units 7 can be made independent of each other, thereby reducing crosstalk between adjacent light-emitting units 7 and improving the display effect of the display panel. At the same time, due to the presence of the isolation structure 10, the light-emitting material layer and the second electrode material layer in each color light-emitting unit 7 of the display panel can be prepared as a whole before patterning, thereby eliminating the need for a fine mask and saving the manufacturing cost of the display panel.

[0194] In some possible implementations, please refer again. Figure 1 and Figure 4a The system comprises multiple pixel groups, including a first pixel group 20A, and a light-emitting unit 7, including a first light-emitting unit 71. The first pixel group 20A includes four adjacent first light-emitting units 71. The via 31 includes multiple first vias 311. The first electrode 4 of the first light-emitting unit 71 is electrically connected to the corresponding driving circuit layer 2 through the first vias 311. The line connecting the centers of the four adjacent first vias 311 corresponding to the same first pixel group 20A on the substrate 1 forms a first virtual quadrilateral 13. The multiple first pixel groups 20A can be arranged in an array, for example, multiple first pixel groups 20A arranged along a first direction or multiple first pixel groups 20A arranged along a second direction. For example, in any two of at least two first pixel groups 20A, the first virtual quadrilateral corresponding to one first pixel group 20A has the same shape and size as the first virtual quadrilateral corresponding to the other first pixel group 20A. The first virtual quadrilateral 13 can be trapezoidal or rectangular.

[0195] In this way, the arrangement of the first via 311 can be more uniform, and the arrangement of the groove 11 corresponding to the first via 311 on the side of the isolation structure 10 away from the substrate 1 can be more uniform. When the display panel is off, the reflection at the groove 11 corresponding to the first via 311 on the isolation structure 10 is more uniform, thereby further improving the display uniformity of the display panel when it is off.

[0196] For example, within the same first pixel group 20A, the four first light-emitting units 71 emit the same color, such as red, green, or blue. Alternatively, within the same first pixel group 20A, for example, two of the first light-emitting units 71 emit the same color, and the other two emit the same color, thus the same first pixel group 20A includes light-emitting units with two different colors, such as red, green, or blue. Optionally, within the same first pixel group 20A, the line connecting the centers of the four first light-emitting units 71 (e.g., light-emitting areas) projected onto the substrate 1 forms a fifth virtual quadrilateral 21. The center of the light-emitting unit can be the center of the projection of the light-emitting area of ​​the light-emitting unit onto the substrate 1. The fifth virtual quadrilateral 21 can be trapezoidal or rectangular.

[0197] Optionally, in the first virtual quadrilateral 13 and the fifth virtual quadrilateral 21 corresponding to the same first pixel group 20A, at least two sides of the first virtual quadrilateral 13 are parallel to at least two sides of the fifth virtual quadrilateral 21.

[0198] Optionally, in the first virtual quadrilateral 13 and the fifth virtual quadrilateral 21 corresponding to the same first pixel group 20A, the four sides of the first virtual quadrilateral 13 are parallel to the four sides of the fifth virtual quadrilateral 21.

[0199] For example, the first virtual quadrilateral 13 and the fifth virtual quadrilateral 21 corresponding to the same first pixel group 20A have the same shape and size, such as equal area and equal side length of corresponding sides. For example, the first virtual quadrilateral 13 and the fifth virtual quadrilateral 21 are trapezoids, or, for example, the first virtual quadrilateral 13 and the fifth virtual quadrilateral 21 are rectangles.

[0200] Optionally, at least three first light-emitting units 71 arranged along the first direction X and corresponding to first vias 311 are arranged along the first direction X.

[0201] Optionally, at least three adjacent first light-emitting units 71 are arranged with their corresponding first vias 311 at equal intervals along the first direction X. For example, the first virtual quadrilateral 13 can be a rectangle. Alternatively, among the three adjacent first light-emitting units 71 arranged along the first direction X, the distance between the first via 311 corresponding to the first light-emitting unit 71 on one side and the first via 311 corresponding to the first light-emitting unit 71 in the middle is a first distance D1, and the distance between the first via 311 corresponding to the first light-emitting unit 71 on the other side and the first via 311 corresponding to the first light-emitting unit 71 in the middle is a second distance D2. The first distance D1 and the second distance D2 are different. One of the lengths of the two opposite sides of the first virtual quadrilateral 13 along the second direction Y is equal to the first distance D1, and the other is equal to the second distance D2. For example, the first virtual quadrilateral 13 can be a trapezoid.

[0202] Optionally, the first via 311 corresponding to the first light-emitting unit 71 is located on one side of the two opposite sides of the first light-emitting unit 71 along the second direction Y; the first direction X and the second direction Y intersect, for example, perpendicularly. For example, among a plurality of first light-emitting units 71, the first via 311 corresponding to the first light-emitting unit 71 is located on the same side of the two opposite sides of the first light-emitting unit 71 along the second direction Y.

[0203] Optionally, the first vias 311 corresponding to at least three adjacent first light-emitting units 71 arranged along the second direction Y are arranged along the second direction Y, for example, the first virtual quadrilateral 13 can be a rectangle; or, among the three adjacent first light-emitting units 71 arranged along the second direction Y, the distance D3 between the first via 311 corresponding to the first light-emitting unit 71 on one side and the first via 311 corresponding to the first light-emitting unit 71 in the middle is equal to the distance D4 between the first via 311 corresponding to the first light-emitting unit 71 on the other side and the first via 311 corresponding to the first light-emitting unit 71 in the middle, for example, the first virtual quadrilateral 13 can be a rectangle or a trapezoid.

[0204] Optionally, the first vias 311 corresponding to two adjacent first light-emitting units 71 arranged along the second direction Y are arranged opposite each other along the second direction, for example, the first virtual quadrilateral 13 can be a rectangle; or, the first vias 311 corresponding to two adjacent first light-emitting units 71 arranged along the second direction Y are arranged at different positions along the second direction Y, for example, the first virtual quadrilateral 13 can be a trapezoid.

[0205] Through the above design, the arrangement of the first via 311 can be more uniform, and the arrangement of the groove 11 corresponding to the first via 311 on the side of the isolation structure 10 away from the substrate 1 can be more uniform. When the display panel is off, the reflection at the groove 11 corresponding to the first via 311 on the isolation structure 10 is more uniform, thereby further improving the display uniformity of the display panel when it is off.

[0206] For example, the isolation structures corresponding to the four first light-emitting units in the same first pixel group 20A are connected into a single structure.

[0207] In some possible implementations, please refer again. Figure 1 , Figure 4aThe system comprises multiple pixel groups, including a second pixel group 20B. Each second pixel group 20B includes two adjacent second light-emitting units 72 and two third light-emitting units 73. The via 31 also includes multiple second vias 312 and multiple third vias 313. The first electrode 4 of each second light-emitting unit 72 is electrically connected to the corresponding driving circuit layer 2 through the second via 312, and the first electrode 4 of each third light-emitting unit 73 is electrically connected to the corresponding driving circuit layer 2 through the third via 313. The line connecting the centers of two adjacent second vias 312 and two third vias 313 projected onto the substrate 1 forms a second virtual quadrilateral 14. The multiple second pixel groups 20B can be arranged in an array, for example, multiple second pixel groups 20B can be arranged along a first direction or multiple second pixel groups 20B can be arranged along a second direction. For example, in any two of the at least two second pixel groups 20B, the second virtual quadrilateral corresponding to one second pixel group 20B has the same shape and size as the second virtual quadrilateral corresponding to the other second pixel group 20B. The second virtual quadrilateral 14 can be a trapezoid or a rectangle.

[0208] In this way, the arrangement of the second via 312 and the third via 313 can be more uniform, and the arrangement of the grooves 11 corresponding to the second via 312 and the third via 313 on the side of the isolation structure 10 away from the substrate 1 can be more uniform. When the display panel is off, the reflection at the grooves 11 corresponding to the second via 312 and the third via 313 on the isolation structure 10 is more uniform, thereby further improving the display uniformity of the display panel when it is off.

[0209] Optionally, the first light-emitting unit 71 and the second light-emitting unit 72 emit different colors, and / or the first light-emitting unit 71 and the third light-emitting unit 73 emit different colors, and / or the second light-emitting unit 72 and the third light-emitting unit 73 emit different colors.

[0210] Optionally, the first light-emitting unit 71 emits light in one of red, green, and blue; and / or, the second light-emitting unit 72 emits light in one of red, green, and blue; and / or, the third light-emitting unit 73 emits light in one of red, green, and blue.

[0211] The first light-emitting unit 71 emits green light, and / or the second light-emitting unit 72 emits red light, and / or the third light-emitting unit 73 emits blue light.

[0212] Optionally, the second via 312 corresponding to the second light-emitting unit 72 is located on one side of the two opposite sides of the second light-emitting unit 72 along the first direction X. For example, in a plurality of second light-emitting units 72, the second via 312 corresponding to the second light-emitting unit 72 is located on the same side of the two opposite sides of the second light-emitting unit 72 along the first direction X.

[0213] Optionally, the third via 313 corresponding to the third light-emitting unit 73 is located on one of the two opposite sides of the third light-emitting unit 73 along the first direction X. For example, in a plurality of third light-emitting units 73, the third via 313 corresponding to the third light-emitting unit 73 is located on the same side of the two opposite sides of the third light-emitting unit 73 along the first direction X.

[0214] Optionally, the second via 312 and the third via 313 are arranged alternately along the first direction X.

[0215] Optionally, the orthographic projection of the centers of the two second vias 312 corresponding to the same second pixel group 20B onto the substrate 1 is located at the opposite corner of the second virtual quadrilateral 14.

[0216] Optionally, the orthographic projection of the centers of the two third vias 313 corresponding to the same second pixel group 20B onto the substrate 1 is located at the opposite corner of the second virtual quadrilateral 14.

[0217] Optionally, among the three first light-emitting units 71 arranged adjacent to each other along the second direction Y, a second through hole 312 is provided between the first light-emitting unit 71 on one side and the first light-emitting unit 71 in the middle, and a third through hole 313 is provided between the first light-emitting unit 71 on the other side and the first light-emitting unit 71 in the middle.

[0218] Optionally, the orthographic projection of the second via 312 (e.g., the center of the second via) onto the substrate 1 is located on the edge of the corresponding first virtual quadrilateral.

[0219] Optionally, the orthographic projection of the third via 313 (e.g., the center of the third via) onto the substrate 1 is located on the edge of the corresponding first virtual quadrilateral.

[0220] Optionally, among the second vias 312 and the third vias 313 corresponding to the same second pixel group 20B, the second vias 312 and the third vias 313 arranged and adjacent along the first direction X, the orthographic projection of the second via 312 on the substrate 1 and the orthographic projection of the third via 313 on the substrate 1 are located on opposite sides of the corresponding first virtual quadrilateral.

[0221] Optionally, among the second vias 312 and the third vias 313 corresponding to the same second pixel group 20B, the orthographic projections of the second vias 312 and the third vias 313 arranged and adjacent along the first direction X are located on opposite sides of the corresponding first virtual quadrilateral arranged along the first direction X.

[0222] Optionally, in the same second pixel group 20B, the line connecting the centers of the two second light-emitting units 72 and the two third light-emitting units 73 on the substrate 1 forms a sixth virtual quadrilateral 22. The sixth virtual quadrilateral 22 can be a trapezoid or a rectangle.

[0223] Optionally, in the second virtual quadrilateral 14 and the sixth virtual quadrilateral 22 corresponding to the same second pixel group 20B, at least two sides of the second virtual quadrilateral 14 are parallel to at least two sides of the sixth virtual quadrilateral 22.

[0225] For example, the second virtual quadrilateral 14 and the sixth virtual quadrilateral 22 corresponding to the same second pixel group 20B have the same shape and size, for example, the same area and the same side length of the corresponding sides. For example, the second virtual quadrilateral 14 and the sixth virtual quadrilateral 22 are trapezoids.

[0226] Optionally, the second via 312 and the third via 313 are arranged alternately along the second direction Y; the second via 312 and the third via 313 corresponding to adjacent second light-emitting units 72 and third light-emitting units 73 are arranged opposite each other along the second direction Y, for example, the second virtual quadrilateral 14 is rectangular; or, the second via 312 and the third via 313 corresponding to adjacent second light-emitting units 72 and third light-emitting units 73 are arranged in a staggered manner along the second direction Y, for example, the second virtual quadrilateral 14 is trapezoidal, and multiple second via 312 are arranged along the second direction Y; multiple third via 313 are arranged along the second direction Y.

[0227] Through the above design, the arrangement of the second via 312 and the third via 313 can be more uniform, and the arrangement of the grooves 11 corresponding to the second via 312 and the third via 313 on the side of the isolation structure 10 away from the substrate 1 can be more uniform. When the display panel is off, the reflection at the grooves 11 corresponding to the second via 312 and the third via 313 on the isolation structure 10 is more uniform, thereby further improving the display uniformity of the display panel when it is off.

[0228] In some possible implementations, please refer again. Figure 4a The orthographic projection of the second light-emitting unit 72 onto the substrate 1 at least partially overlaps with the first virtual quadrilateral 13.

[0229] Optionally, the orthographic projection of the third light-emitting unit 73 onto the substrate 1 at least partially overlaps with the first virtual quadrilateral 13.

[0230] Optionally, the orthographic projection of the first light-emitting unit 71 onto the substrate 1 at least partially overlaps with the second virtual quadrilateral 14.

[0231] Optionally, the second light-emitting unit 72 and the third light-emitting unit 73 are arranged alternately along the row direction X, and a plurality of first light-emitting units 71 are arranged sequentially along the row direction X. The second light-emitting unit 72 and the third light-emitting unit 73 may also be arranged alternately along the column direction Y, and a plurality of first light-emitting units 71 may also be arranged sequentially along the column direction Y.

[0232] In some embodiments, in the tripod-shaped pixel arrangement, please refer again to... Figure 4a The first virtual quadrilateral 13 and the second virtual quadrilateral 14 include trapezoids; please refer to [link / reference]. Figure 4b The first virtual quadrilateral 13 and the second virtual quadrilateral 14 include rectangles.

[0233] In other embodiments, in the standard pixel arrangement, please refer to... Figure 5a The first virtual quadrilateral 13 and the second virtual quadrilateral 14 include rectangles; please refer to [link / reference]. Figure 5b The first virtual quadrilateral 13 and the second virtual quadrilateral 14 include trapezoids.

[0234] For the standard pixel layout, please refer again. Figure 5a The first light-emitting unit, the second light-emitting unit, and the third light-emitting unit are all rectangular in shape.

[0235] In the same first pixel group, the line connecting the centers of the four first light-emitting units projected onto the substrate forms a fifth virtual quadrilateral 21. The fifth virtual quadrilateral 21 has the same shape and size as the first virtual quadrilateral 13.

[0236] In the same second pixel group, the line connecting the center of the two second light-emitting units and the center of the two third light-emitting units on the substrate forms a sixth virtual quadrilateral 22. The sixth virtual quadrilateral 22 has the same shape and size as the second virtual quadrilateral 14.

[0237] For example, a third pixel group includes four adjacent second light-emitting units 72. For example, in any two of at least two third pixel groups, the virtual quadrilateral formed by the lines connecting the centers of the vias corresponding to the four second light-emitting units 72 in one third pixel group on the substrate through their orthogonal projections is the same shape and size as the virtual quadrilateral formed by the lines connecting the centers of the vias 72 corresponding to the four second light-emitting units in the other third pixel group on the substrate through their orthogonal projections. Figure 5cAs shown. For example, in the same third pixel group, the eighth virtual quadrilateral 24 formed by the lines connecting the centers of the four second light-emitting units 72 on the substrate through their orthogonal projections is the same shape and size as the fifth virtual quadrilateral 21. Similarly, the eighth virtual quadrilateral 24 formed by the lines connecting the centers of the four second light-emitting units 72 on the substrate through their orthogonal projections is the same shape and size as the seventh virtual quadrilateral 23 formed by the lines connecting the centers of the vias corresponding to the four second light-emitting units 72 on the substrate through their orthogonal projections.

[0238] For example, the fourth pixel group includes four adjacent third light-emitting units 73. For example, in any two fourth pixel groups within at least two fourteenth pixel groups, the virtual quadrilateral formed by the lines connecting the orthographic projections of the centers of the vias corresponding to the four third light-emitting units 73 in one fourth pixel group onto the substrate is the same shape and size as the virtual quadrilateral formed by the lines connecting the orthographic projections of the centers of the vias corresponding to the third light-emitting units 73 in the other fourth pixel group onto the substrate. Figure 5c As shown. For example, in the same fourth pixel group, the tenth virtual quadrilateral 26 formed by the lines connecting the centers of the four third light-emitting units 73 on the substrate through their orthogonal projections is the same shape and size as the fifth virtual quadrilateral 21. Similarly, in the same third pixel group, the tenth virtual quadrilateral 26 formed by the lines connecting the centers of the third light-emitting units 73 on the substrate through their orthogonal projections is the same shape and size as the ninth virtual quadrilateral 25 formed by the lines connecting the centers of the vias corresponding to the four third light-emitting units 73 on the substrate through their orthogonal projections.

[0239] In this way, the arrangement of light-emitting units in the standard arrangement can be more uniform, and the arrangement of the grooves 11 on the side of the isolation structure 10 away from the substrate 1 can also be more uniform and regular. When the display panel is off, the reflection of the grooves 11 on the side of the isolation structure 10 away from the substrate 1 is more uniform and regular, thereby improving the display uniformity of the display panel when it is off.

[0240] For example, the orthographic projection of the isolation opening onto the substrate includes a first edge and a second edge 902. The extension length of the first edge is less than the extension length of the second edge. The orthographic projection of the via onto the substrate is located on the side closer to the first edge. The light-emitting unit includes a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit with different emitting colors. The vias corresponding to the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit are located on the same side of their respective sides along the second direction Y. Multiple first light-emitting units are arranged along the second direction Y, multiple second light-emitting units are arranged along the second direction Y, and multiple third light-emitting units are arranged along the second direction Y. The first light-emitting unit, the second light-emitting unit, and the third light-emitting unit are arranged sequentially and cyclically along the first direction X. The first direction X intersects the second direction Y.

[0241] For example, the first virtual quadrilateral 13 and the second virtual quadrilateral 14 can have the same shape. For example, the first virtual quadrilateral 13 and the second virtual quadrilateral 14 can have the same shape, the same area, and the same side length for corresponding sides.

[0242] Thus, in different pixel arrangement methods, the above solution can make the arrangement of vias 31 more uniform, and make the display panel more uniform when the screen is off.

[0243] For example, the isolation structures corresponding to the two second light-emitting units and the two third light-emitting units in the same second pixel group 20B are connected into a single structure.

[0244] Optionally, the first arrangement structure formed by the second light-emitting unit 72 and the third light-emitting unit 73 arranged alternately along the first direction X, and the second arrangement structure formed by the plurality of first light-emitting units 71 arranged along the first direction X, are arranged alternately along the second direction Y, with the first direction X and the second direction Y intersecting.

[0245] Optionally, the second light-emitting unit 72 and the third light-emitting unit 73 are arranged alternately along the second direction Y.

[0246] Optionally, multiple first light-emitting units 71 are arranged sequentially along the second direction Y.

[0247] Optionally, the third arrangement structure formed by the second light-emitting unit 72 and the third light-emitting unit 73 arranged alternately along the second direction Y, and the fourth arrangement structure formed by the plurality of first light-emitting units 71 arranged along the second direction Y, are arranged alternately along the first direction X.

[0248] Optionally, the first light-emitting unit 71 and the second light-emitting unit 72 are arranged alternately along the third direction V.

[0249] Optionally, the first light-emitting unit 71 and the third light-emitting unit 73 are arranged sequentially along the third direction V.

[0250] Optionally, the fifth arrangement structure formed by the alternating arrangement of the first light-emitting unit 71 and the second light-emitting unit 72 along the third direction V alternates with the sixth arrangement structure formed by the sequential arrangement of the first light-emitting unit 71 and the third light-emitting unit 73 along the third direction V; any two of the first direction X, the second direction Y, the third direction V and the fourth direction W intersect.

[0251] Optionally, the first light-emitting unit 71 and the second light-emitting unit 72 are arranged alternately along the fourth direction W.

[0252] Optionally, the first light-emitting unit 71 and the third light-emitting unit 73 are arranged sequentially along the fourth direction W.

[0253] Optionally, the seventh arrangement structure formed by the alternating arrangement of the first light-emitting unit 71 and the second light-emitting unit 72 along the fourth direction W, and the eighth arrangement structure formed by the sequential arrangement of the first light-emitting unit 71 and the third light-emitting unit 73 along the fourth direction W, are alternately arranged along the third direction V.

[0254] Optionally, the first direction X is perpendicular to the second direction Y, the third direction V is perpendicular to the fourth direction W, and the angle between the first direction X and the third direction V is 45 degrees.

[0255] Through the above design, the arrangement of the first light-emitting unit 71, the second light-emitting unit 72, and the third light-emitting unit 73 can be made more uniform, thereby making the arrangement of the first via 311, the second via 312, and the third via 313 more uniform. The arrangement of the grooves 11 corresponding to the first via 311, the second via 312, and the third via 313 on the side of the isolation structure 10 away from the substrate 1 is more uniform. When the display panel is off, the reflection at the grooves 11 corresponding to the first via 311, the second via 312, and the third via 313 on the isolation structure 10 is more uniform, thereby further improving the display uniformity of the display panel when it is off.

[0256] For some possible implementations, please refer to Figure 1 , Figure 4a , Figure 6a and Figure 6b The groove 11 includes a first groove 111. The orthographic projection of the first groove 111 on the substrate 1 is located within the orthographic projection of the first via 311 on the substrate 1. The line connecting the orthographic projections of the centers of four adjacent first grooves 111 corresponding to the same first pixel group 20A on the substrate 1 forms a third virtual quadrilateral 15.

[0257] In this way, the arrangement of the first groove 111 can be more uniform, and the reflection at the first groove 111 is more uniform when the display panel is off, thereby further improving the display uniformity when the display panel is off.

[0258] Optionally, please see again Figure 1 , Figure 6a and Figure 6b The groove 11 includes a second groove 112 and a third groove 113. The orthographic projection of the second groove 112 on the substrate 1 is located within the orthographic projection of the second via 312 on the substrate 1. The orthographic projection of the third groove 113 on the substrate 1 is located within the orthographic projection of the third via 313 on the substrate 1. The line connecting the centers of two adjacent second grooves 112 and two third grooves 113 corresponding to the same second pixel group 20B on the substrate 1 forms a fourth virtual quadrilateral 16.

[0259] Optionally, the orthographic projection of the groove 11 on the substrate 1 is located between the orthographic projections of two adjacent isolation openings 9 on the substrate 1.

[0260] In this way, the arrangement of the second groove 112 and the third groove 113 can be more uniform, and the reflection at the second groove 112 and the third groove 113 is more uniform when the display panel is off, thereby further improving the display uniformity when the display panel is off.

[0261] In some possible implementations, please refer again. Figure 1 , Figure 4a , Figure 6a and Figure 6b The isolation opening 9 includes a first isolation opening 91, a second isolation opening 92 and a third isolation opening 93. At least a portion of the first light-emitting unit 71 is located in the first isolation opening 91, at least a portion of the second light-emitting unit 72 is located in the second isolation opening 92, and at least a portion of the third light-emitting unit 73 is located in the third isolation opening 93. The orthographic projection of the second isolation opening 92 on the substrate 1 at least partially coincides with the third virtual quadrilateral 15.

[0262] Optionally, the orthographic projection of the third isolation opening 93 onto the substrate 1 at least partially coincides with the third virtual quadrilateral 15.

[0263] Optionally, the orthographic projection of the first isolation opening 91 onto the substrate 1 at least partially coincides with the fourth virtual quadrilateral 16.

[0264] For example, the four sides of the first virtual quadrilateral and the third virtual quadrilateral corresponding to the same first pixel group 20A are identical.

[0265] For example, the four sides of the second virtual quadrilateral corresponding to the second pixel group 20B coincide with those of the fourth virtual quadrilateral.

[0266] In some embodiments, in the tripod-shaped pixel arrangement, please refer again to... Figure 6a The third virtual quadrilateral 15 and the fourth virtual quadrilateral 16 include trapezoids; please refer again. Figure 6b The third virtual quadrilateral 15 and the fourth virtual quadrilateral 16 include rectangles.

[0267] In other embodiments, in the standard pixel arrangement, please refer to... Figure 7a The third virtual quadrilateral 15 and the fourth virtual quadrilateral 16 include rectangles; please refer to [link / reference]. Figure 7b The third virtual quadrilateral 15 and the fourth virtual quadrilateral 16 include trapezoids.

[0268] Thus, in different pixel arrangement methods, the above scheme can make the arrangement of the grooves 11 on the side of the isolation structure 10 away from the substrate 1 more uniform, and make the display panel more uniform when the screen is off.

[0269] For example, in the same first pixel group, the line connecting the centers of the four first light-emitting units projected onto the substrate forms a fifth virtual quadrilateral 21. The fifth virtual quadrilateral 21 has the same shape and size as the third virtual quadrilateral 15.

[0270] For example, in the same second pixel group, the line connecting the center of the two second light-emitting units and the center of the two third light-emitting units on the substrate forms a sixth virtual quadrilateral 22. The sixth virtual quadrilateral 22 has the same shape and size as the third virtual quadrilateral 15.

[0271] For example, in the same third pixel group, the virtual quadrilateral formed by the lines connecting the centers of the four second light-emitting units 72 on the substrate through their orthogonal projections is the same shape and size as the fifth virtual quadrilateral 21. Similarly, in the same third pixel group, the virtual quadrilateral formed by the lines connecting the centers of the four second light-emitting units 72 on the substrate through their orthogonal projections is the same shape and size as the virtual quadrilateral formed by the lines connecting the centers of the corresponding grooves of the four second light-emitting units 72 on the substrate through their orthogonal projections.

[0272] For example, in the same fourth pixel group, the virtual quadrilateral formed by the lines connecting the centers of the four third light-emitting units 73 on the substrate through their orthogonal projections is the same shape and size as the fifth virtual quadrilateral 21. Similarly, in the same fourth pixel group, the virtual quadrilateral formed by the lines connecting the centers of the third light-emitting units 73 on the substrate through their orthogonal projections is the same shape and size as the virtual quadrilateral formed by the lines connecting the centers of the corresponding grooves of the four third light-emitting units 73 on the substrate through their orthogonal projections.

[0273] For some possible implementations, please refer to Figure 8 The display panel also includes a first encapsulation layer 17 located on the side of the light-emitting unit 7 away from the substrate 1. The first encapsulation layer 17 includes a plurality of encapsulation units 171, which are located on the side of the corresponding light-emitting unit away from the substrate. At least some of the encapsulation units 171 extend from the side of the isolation structure 10 toward the isolation opening 9 to the side of the isolation structure 10 away from the substrate 1.

[0274] Optionally, at least two adjacent packaging units 171 are spaced apart on the side of the isolation structure 10 away from the substrate 1, and there is a gap between the packaging unit 171 on the side of the isolation structure 10 away from the substrate 1 and the side of the isolation structure 10 away from the substrate 1.

[0275] During the patterning process of the light-emitting unit 7, the first encapsulation material layer is broken at the isolation structure 10 to form an encapsulation unit 171. The encapsulation unit 171 can completely and independently encapsulate the corresponding light-emitting unit 7, thereby improving the display characteristics of the display panel.

[0276] For some possible implementations, please refer to Figure 9The display panel also includes a second encapsulation layer 18 located on the side of the first encapsulation layer 17 away from the substrate 1.

[0277] For example, the display panel also includes a third encapsulation layer 19 located on the side of the second encapsulation layer 18 away from the substrate 1.

[0278] Optionally, the material of the first encapsulation layer 17 includes inorganic materials, and / or the material of the third encapsulation layer 19 includes inorganic materials, and / or the material of the second encapsulation layer 18 includes organic materials.

[0279] For example, the first encapsulation layer 17 and the third encapsulation layer 19 can be formed by chemical vapor deposition (CVD), and the second encapsulation layer 18 can be formed by inkjet printing (IJP). The second encapsulation layer 18 and the third encapsulation layer 19 can achieve a better encapsulation effect on the light-emitting unit 7, thereby further improving the encapsulation quality of the display panel.

[0280] For example, the isolation structure 10 may include a conductive material, and the isolation structure 10 is electrically connected to the second electrode.

[0281] For example, the isolation structure can be a mesh-like structure. For instance, the isolation structures corresponding to the first, second, and third light-emitting units can be connected into a single, integrated structure, forming a mesh-like structure.

[0282] In some possible implementations, please refer again. Figure 8 The isolation structure 10 includes a first isolation portion 101 and a second isolation portion 102 stacked sequentially along a direction away from the substrate 1. The orthographic projection of the side of the first isolation portion 101 away from the substrate 1 on the substrate 1 is located within the orthographic projection of the second isolation portion 102 on the substrate 1.

[0283] Since the second isolation portion 102 is located on the side of the first isolation portion 101 away from the substrate, and on a plane parallel to the substrate, the lateral width of the second isolation portion 102 is greater than the lateral width of the first isolation portion 101. Therefore, the second isolation portion 102 causes the light-emitting material layer and the second electrode material layer to be disconnected at the isolation structure 10. In this way, the isolation structure 10 formed by the first isolation portion 101 and the second isolation portion 102 makes it easier to independently package each light-emitting unit 7, thereby improving the packaging yield of the display panel.

[0284] Please see again Figure 8 The second electrode 6 of the light-emitting unit 7 is electrically connected to the first isolation part 101. The first isolation part 101 includes a conductive material, and the second electrode 6 corresponding to the light-emitting unit 7 extends to contact the side wall of the first isolation part 101 so as to realize the electrical connection between the second electrode 6 corresponding to the light-emitting unit 7 and the first isolation part 101.

[0285] Please see again Figure 9 The isolation structure 10 also includes a third isolation portion 103 located on the side of the first isolation portion 101 facing the substrate 1, for example, the second electrode 6 of the light-emitting unit 7 is electrically connected to the third isolation portion 103.

[0286] The third isolation section 103 includes a conductive material, and the second electrode 6 corresponding to the light-emitting unit 7 extends to contact the side wall of the third isolation section 103 so as to realize the electrical connection between the second electrode 6 corresponding to the light-emitting unit 7 and the third isolation section 103.

[0287] Specifically, the material of the third isolation portion 103 includes molybdenum; and / or, the material of the first isolation portion 101 includes aluminum; and / or, the material of the second isolation portion 102 includes titanium. Thus, when the isolation structure 10 isolates the second electrode material layer into the second electrode 6, the second electrode 6 is more easily electrically connected to the first isolation portion 101 and / or the third isolation portion 103.

[0288] The orthographic projection of the light-emitting portion 5 onto the substrate is outside the orthographic projection of the third isolation portion 103 and / or the first isolation portion 101 onto the substrate. Thus, the light-emitting portion 5 does not overlap with the isolation structure 10, thereby effectively improving the crosstalk problem between the light-emitting units 7.

[0289] In some possible implementations, please refer again. Figure 2 and Figure 6a This application also provides another display panel, which includes a substrate 1, an isolation structure 10, and a plurality of pixel groups.

[0290] The isolation structure 10 is located on one side of the substrate 1. The isolation structure 10 encloses and forms an isolation opening 9. The side of the isolation structure 10 away from the substrate 1 has a groove 11 recessed in the direction of the substrate 1.

[0291] Each pixel group includes at least two light-emitting units 7, at least some of the light-emitting units 7 are located within the isolation opening 9, and in any two pixel groups of at least two pixel groups, the arrangement of the multiple grooves 11 corresponding to the multiple light-emitting units 7 in one pixel group is the same as the arrangement of the multiple grooves 11 corresponding to the multiple light-emitting units 7 in the other pixel group.

[0292] Since the arrangement of the multiple recesses 11 corresponding to the multiple light-emitting units 7 in one pixel group is the same as the arrangement of the multiple recesses 11 corresponding to the multiple light-emitting units 7 in the other pixel group, the arrangement of the recesses 11 on the side of the isolation structure 10 away from the substrate 1 is more uniform. When the display panel is off, the reflection of the recesses 11 on the side of the isolation structure 10 away from the substrate 1 is more uniform, thereby improving the display uniformity of the display panel when it is off.

[0293] In some possible implementations, please refer again. Figure 1 , Figure 3 , Figure 4a and Figure 6a The system comprises multiple pixel groups, including a first pixel group 20A, a light-emitting unit 7 including a first light-emitting unit 71, a first pixel group 20A including four adjacent first light-emitting units, a groove 11 including a first groove 111, and a first light-emitting unit 71 corresponding to a first groove 111, for example, in a one-to-one correspondence. The line connecting the centers of four adjacent first grooves 111 corresponding to the same first pixel group 20A on the substrate 1 forms a third virtual quadrilateral 15. For example, in any two of the at least two first pixel groups 20A, the third virtual quadrilateral corresponding to one first pixel group 20A has the same shape and size as the third virtual quadrilateral corresponding to the other first pixel group 20A.

[0294] In this way, the arrangement of the first groove 111 can be more uniform, and the reflection at the first groove 111 is more uniform when the display panel is off, thereby further improving the display uniformity when the display panel is off.

[0295] Preferably, please see again. Figure 1 , Figure 3 , Figure 4a and Figure 6a The system comprises multiple pixel groups, including a second pixel group 20B. The light-emitting unit 7 includes a second light-emitting unit 72 and a third light-emitting unit 73. Each second pixel group 20B includes two adjacent second light-emitting units and two adjacent third light-emitting units. The groove 11 includes a second groove 112 and a third groove 113. The second light-emitting unit 72 corresponds to the second groove 112, for example, in a one-to-one correspondence. The third light-emitting unit 73 corresponds to the third groove 113, for example, in a one-to-one correspondence. The line connecting the centers of two adjacent second grooves 112 and two adjacent third grooves 113 corresponding to the same second pixel group 20B, projected onto the substrate 1, forms a fourth virtual quadrilateral 16. For example, in any two of the at least two second pixel groups 20B, the fourth virtual quadrilateral corresponding to one second pixel group 20B has the same shape and size as the fourth virtual quadrilateral corresponding to the other second pixel group 20B.

[0296] In some possible implementations, please refer again. Figure 1 , Figure 3 , Figure 4a and Figure 6a In the third virtual quadrilateral 15 and the fifth virtual quadrilateral 21 corresponding to the same first pixel group 20A, at least two sides of the third virtual quadrilateral 15 are parallel to at least two sides of the fifth virtual quadrilateral 21.

[0297] Optionally, in the third virtual quadrilateral 15 and the fifth virtual quadrilateral 21 corresponding to the same first pixel group 20A, the four sides of the third virtual quadrilateral 15 are parallel to the four sides of the fifth virtual quadrilateral 21.

[0298] For example, the first virtual quadrilateral and the fifth virtual quadrilateral corresponding to the same first pixel group 20A have the same shape and the same size.

[0299] Optionally, at least three adjacent first light-emitting units 71 are arranged along the first direction X, and their corresponding first grooves 111 are arranged along the first direction X.

[0300] Optionally, the first grooves 111 corresponding to at least three adjacent first light-emitting units 71 arranged along the first direction X are arranged at equal intervals along the first direction X, for example, the third virtual quadrilateral 15 is a rectangle; or, among the three adjacent first light-emitting units 71 arranged along the first direction X, the distance between the first groove 111 corresponding to the first light-emitting unit 71 on one side and the first groove 111 corresponding to the first light-emitting unit 71 in the middle is a third distance D5, and the distance between the first groove 111 corresponding to the first light-emitting unit 71 on the other side and the first groove 111 corresponding to the first light-emitting unit 71 in the middle is a fourth distance D6. The third distance D5 and the fourth distance D6 are different. One of the lengths of the two opposite sides of the third virtual quadrilateral 15 along the second direction is equal to the third distance D5, and the other is equal to the fourth distance D6. For example, the third virtual quadrilateral 15 is a trapezoid.

[0301] Optionally, the first groove 111 corresponding to the first light-emitting unit 71 is located on one side of the two opposite sides of the first light-emitting unit 71 along the second direction; the first direction X and the second direction Y intersect. For example, among a plurality of first light-emitting units 71, the first groove 111 corresponding to the first light-emitting unit 71 is located on the same side of the two opposite sides of the first light-emitting unit 71 along the second direction, for example, the left side.

[0302] Optionally, the first grooves 111 corresponding to at least three adjacent first light-emitting units 71 arranged along the second direction Y are arranged along the second direction Y, for example, the third virtual quadrilateral 15 is a rectangle; or, among the three adjacent first light-emitting units 71 arranged along the second direction Y, the distance D7 between the first groove 111 corresponding to the first light-emitting unit 71 on one side and the first groove 111 corresponding to the first light-emitting unit 71 in the middle is equal to the distance D8 between the first groove 111 corresponding to the first light-emitting unit 71 on the other side and the first groove 111 corresponding to the first light-emitting unit 71 in the middle, for example, the third virtual quadrilateral 15 is a trapezoid or a rectangle.

[0303] Optionally, the first grooves 111 corresponding to two adjacent first light-emitting units 71 arranged along the second direction Y are arranged opposite each other along the second direction Y, for example, the third virtual quadrilateral 15 is rectangular; or, the first grooves 111 corresponding to two adjacent first light-emitting units 71 arranged along the second direction Y are staggered along the second direction Y, for example, the third virtual quadrilateral 15 is trapezoidal.

[0304] In some possible implementations, the second groove 112 corresponding to the second light-emitting unit 72 is located on one side of the two opposite sides of the second light-emitting unit 72 along the first direction X. For example, in a plurality of second light-emitting units 72, the second groove 112 corresponding to the second light-emitting unit 72 is located on the same side of the two opposite sides of the second light-emitting unit 72 along the first direction X.

[0305] Optionally, the third groove 113 corresponding to the third light-emitting unit 73 is located on one side of the two opposite sides of the third light-emitting unit 73 along the first direction X. For example, in a plurality of third light-emitting units 73, the third groove 113 corresponding to the third light-emitting unit 73 is located on the same side of the two opposite sides of the third light-emitting unit 73 along the first direction X.
