DETAILED DESCRIPTION

[0108] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0109] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0110] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0111] For a better understanding, some explanations are given before going into detail:

[0112] Resolution: Display resolution refers to the precision of the displayed image, specifically, how many sub-pixels (or light-emitting elements) the display can display. For example, common resolutions are HD: 720*1280, FHD: 1080*1920, QHD: 1440*2560, and UHD (2K\4K): 2160*3840. Taking FHD as an example, it means that there are 1080 R sub-pixels, 1080 G sub-pixels, and 1080 B sub-pixels in one direction, and 1920 R sub-pixels, 1920 G sub-pixels, and 1920 B sub-pixels in the other direction.

[0113] PPI (Pixels Per Inch): Also known as pixel density, it indicates the number of pixels in one inch. For example, FHD resolution and 5-inch size have 441 PPI. Therefore, it can be considered that under the premise that the size of the display is certain, the higher the resolution, the higher the PPI.

[0114] The contents of the isolation structure mentioned below are further described in 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 for reference.

[0115] First, refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a display panel 10, which may be an organic light emitting diode display (Organic Light Emitting Diode, OLED) or a quantum dot electroluminescent display (Quantum Dot Light Emitting Diodes, QLED).

[0116] Specifically, the display panel 10 includes an array substrate 11, an isolation structure 12, and a plurality of light-emitting elements 13. The isolation structure 12 is disposed on one side of the array substrate 11, and includes a plurality of isolation openings 12a1, that is, the isolation structure 12 encloses a plurality of isolation openings 12a1. The plurality of light-emitting elements 13 are disposed on one side of the array substrate 11 and are arranged corresponding to the plurality of isolation openings 12a1; at least a portion of the light-emitting elements 13 is disposed in the corresponding isolation openings 12a1; and the plurality of light-emitting elements 13 include at least two light-emitting elements 13 with different luminous colors.

[0117] At least two light emitting elements 13 are disposed in at least one isolation opening 12 a 1 , and the light emitting elements 13 in the same isolation opening 12 a 1 emit the same light-emitting color.

[0118] It is understandable that the array substrate 11 may include a substrate and a semiconductor layer, an insulating layer, a metal layer, a planarization layer, etc. arranged on the substrate. A pixel driving circuit is arranged in the array substrate 11, and the pixel driving circuit is connected to the light-emitting element 13 to drive the light-emitting element 13 to emit light. The pixel driving circuit includes components such as transistors and storage capacitors. The substrate may be a flexible substrate, such as a polyimide (PI) substrate, a polyethylene terephthalate (PET) substrate, or a polymethyl methacrylate (PMMA) substrate. The substrate may also be a rigid substrate, such as glass.

[0119] In some embodiments, the light emitting element 13 includes a first electrode 131, a light emitting functional part 132, and a second electrode 133 stacked in a direction away from the array substrate 11. The first electrode 131 may be an anode, the second electrode 133 may be a cathode, and the light emitting functional part 132 includes at least a light emitting layer (EML), and may also include a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole blocking layer (HBL), and an electron blocking layer (EBL). Alternatively, the light emitting functional part 132 may also be a stacked light emitting structure, that is, including at least two light emitting layers and a charge generation layer (CGL) located between each adjacent light emitting layer.

[0120] It is understandable that the light-emitting layers in the light-emitting functional parts 132 of the light-emitting elements 13 of different colors are different. Figure 2As shown, for a single light-emitting element 13, the entire structure of the first electrode 131, the entire structure of the light-emitting functional part 132 and the entire structure of the second electrode 133 together constitute a light-emitting element 13, and the light-emitting area of ​​the light-emitting element 13 is determined by the contact area between the light-emitting functional part 132 and the first electrode 131, that is, the area where the light-emitting functional part 132 contacts the first electrode 131 is the light-emitting area. Exemplarily, when a pixel defining layer 14 is provided on the array substrate 11, the pixel defining layer 14 encloses a pixel opening 14a, and at least part of the light-emitting element 13 is located in the pixel opening 14a. Specifically, the area enclosed by one end of the pixel opening 14a close to the array substrate 11 is the light-emitting area. It should be noted that in the planar drawings provided in the embodiments of the present application, the light-emitting element 13 in the isolation opening 12a1 represents the light-emitting area of ​​the light-emitting element 13.

[0121] The display panel 10 provided in the embodiment of the present application, by arranging at least two light-emitting elements 13 of the same light-emitting color in at least one isolation opening 12a1, there is no isolation structure 12 between the two light-emitting elements 13, and the distance (gap) between the light-emitting areas of the two light-emitting elements 13 will not be constrained by the isolation structure 12 and can be reduced to the greatest extent, thereby shortening the distance (gap) between the light-emitting areas of the two light-emitting elements 13, improving the area utilization in the display area, thereby improving the aperture ratio, resolution and PPI, and further improving the display effect.

[0122] It should be noted that, by disposing at least two light-emitting elements 13 with the same light-emitting color in a larger number of isolation openings 12a1, it is beneficial to further improve the aperture ratio, resolution and PPI.

[0123] In one embodiment, each isolation opening 12a1 is provided with at least two light emitting elements 13. For example, each isolation opening 12a1 may be provided with 2, 3, 4, 5 or more light emitting elements 13 of the same color. This is beneficial to further improve the aperture ratio, resolution and PPI.

[0124] In one embodiment, referring to Figure 1 and Figure 3As shown, the isolation structure 12 includes a plurality of isolation opening groups 12a, each isolation opening group 12a includes a plurality of isolation openings 12a1, and the plurality of isolation openings 12a1 include at least one first isolation opening 12a11, at least one second isolation opening 12a12, and at least one third isolation opening 12a13, that is, each isolation opening group 12a includes at least one first isolation opening 12a11, at least one second isolation opening 12a12, and at least one third isolation opening 12a13. The plurality of light-emitting elements 13 include a plurality of first light-emitting elements 13a, a plurality of second light-emitting elements 13b, and a plurality of third light-emitting elements 13c, and the light-emitting colors of the first light-emitting elements 13a, the second light-emitting elements 13b, and the third light-emitting elements 13c are different; illustratively, the first light-emitting elements 13a, the second light-emitting elements 13b, and the third light-emitting elements 13c can be used to emit red light, blue light, and green light, respectively. The first light emitting element 13a is disposed corresponding to the first isolation opening 12a11, the second light emitting element 13b is disposed corresponding to the second isolation opening 12a12, and the third light emitting element 13c is disposed corresponding to the third isolation opening 12a13.

[0125] It should be noted that the light emitting elements 13 in the display panel 10 are usually arranged in a fixed arrangement, and the arrangement usually includes a minimum repeatable unit, and the repeatable unit usually includes at least one first light emitting element 13a, at least one second light emitting element 13b and at least one third light emitting element 13c. The isolation opening group 12a here can correspond to the repeatable unit. The arrangement of the isolation opening group 12a can be the same as the arrangement of the repeatable unit.

[0126] Optionally, at least two first light emitting elements 13a are disposed in the first isolation opening 12a11. Exemplarily, two, three, four or more first light emitting elements 13a may be disposed in the first isolation opening 12a11. This is conducive to further improving the aperture ratio, resolution and PPI.

[0127] Optionally, at least two second light emitting elements 13b are disposed in the second isolation opening 12a12. Exemplarily, two, three, four or more second light emitting elements 13b may be disposed in the second isolation opening 12a12. This is beneficial to further improve the aperture ratio, resolution and PPI.

[0128] Optionally, at least two third light emitting elements 13c are disposed in the third isolation opening 12a13. Exemplarily, two, three, four or more third light emitting elements 13c may be disposed in the third isolation opening 12a13. This is conducive to further improving the aperture ratio, resolution and PPI.

[0129] It should be noted that the number of the first light emitting elements 13a in the first isolation opening 12a11, the number of the second light emitting elements 13b in the second isolation opening 12a12, and the number of the third light emitting elements 13c in the third isolation opening 12a13 may be different.

[0130] In one embodiment, in the same isolation opening group 12a, the number of light emitting elements 13 is an integral multiple of the number of isolation openings 12a1. This is conducive to making the number of light emitting elements 13 and the number of isolation openings 12a1 correspond neatly, and to making the number ratio of the first isolation opening 12a11 to the first light emitting element 13a, the number ratio of the second isolation opening 12a12 to the second light emitting element 13b, and the number ratio of the third isolation opening 12a13 to the third light emitting element 13c consistent, thereby facilitating display uniformity.

[0131] Optionally, the number of light emitting elements 13 in the first isolation opening 12a11, the number of light emitting elements 13 in the second isolation opening 12a12, and the number of light emitting elements 13 in the third isolation opening 12a13 are all equal. In this way, the ratio of the number of the first isolation opening 12a11 and the first light emitting element 13a, the ratio of the number of the second isolation opening 12a12 and the second light emitting element 13b, and the ratio of the number of the third isolation opening 12a13 and the third light emitting element 13c can be made equal, which is conducive to ensuring display uniformity.

[0132] In one embodiment, the isolation opening group 12a includes a first isolation opening 12a11, a second isolation opening 12a12 and a third isolation opening 12a13.

[0133] Optionally, refer to Figure 1 , Figure 3 and Figure 5 As shown, two first light-emitting elements 13a are provided in the first isolation opening 12a11, two second light-emitting elements 13b are provided in the second isolation opening 12a12, and two third light-emitting elements 13c are provided in the third isolation opening 12a13. In this way, on the one hand, the aperture ratio, resolution and PPI can be improved; on the other hand, the number of light-emitting elements 13 in each isolation opening 12a1 can be minimized, thereby reducing the risk of large-scale failure of the light-emitting elements 13. It should be added here that, under normal circumstances, when a light-emitting element 13 in the same isolation opening 12a1 is corroded by water vapor and fails, the water vapor will spread along the light-emitting material, thereby causing all the light-emitting elements 13 in the same isolation opening 12a1 to fail. Therefore, minimizing the number of light-emitting elements 13 in the same isolation opening 12a1 can reduce the risk of a large number of light-emitting elements 13 failing at the same time.

[0134] Optionally, refer to Figure 6As shown, three first light emitting elements 13a are disposed in the first isolation opening 12a11, three second light emitting elements 13b are disposed in the second isolation opening 12a12, and three third light emitting elements 13c are disposed in the third isolation opening 12a13. This is conducive to further improving the aperture ratio, resolution and PPI.

[0135] In one embodiment, referring to Figure 5 and Figure 6 As shown, multiple isolation openings 12a1 in the same isolation opening group 12a are arranged at intervals along the first direction X; the first direction X is perpendicular to the thickness direction of the array substrate 11. In this way, the isolation openings 12a1 in the isolation opening group 12a can be arranged more regularly, which is conducive to improving the display effect.

[0136] Optionally, within the same isolation opening group 12 a , the first isolation opening 12 a 11 , the second isolation opening 12 a 12 , and the third isolation opening 12 a 13 are arranged in sequence along the first direction X.

[0137] Optionally, all the first light emitting elements 13a in the first isolation opening 12a11 are arranged at intervals along the second direction Y, and the second direction Y is perpendicular to the thickness direction of the array substrate 11 and intersects with the first direction X. In this way, all the first light emitting elements 13a in the first isolation opening 12a11 can be arranged more regularly, which is conducive to improving the display effect.

[0138] In a preferred embodiment, the second direction Y is perpendicular to the first direction X.

[0139] Optionally, refer to Figure 1 As shown, the sum of the sizes of the light-emitting areas of all the first light-emitting elements 13a in the first isolation opening 12a11 along the second direction Y is smaller than the size of the first isolation opening 12a11 along the second direction Y. Specifically, the size of the first isolation opening 12a11 along the second direction Y is the length of the first isolation opening 12a11, and the size of the light-emitting area of ​​the first light-emitting element 13a along the second direction Y is the length of the light-emitting area of ​​the first light-emitting element 13a. In this way, it is ensured that the two first light-emitting elements 13a can be arranged in the length direction of the first isolation opening 12a11.

[0140] Optionally, all the second light emitting elements 13b in the second isolation opening 12a12 are arranged at intervals along the second direction Y. In this way, all the second light emitting elements 13b in the second isolation opening 12a12 can be arranged more regularly, which is beneficial to improving the display effect.

[0141] Optionally, the sum of the sizes of the light-emitting areas of all the second light-emitting elements 13b in the second isolation opening 12a12 along the second direction Y is smaller than the size of the second isolation opening 12a12 along the second direction Y. Specifically, the size of the second isolation opening 12a12 along the second direction Y is the length of the second isolation opening 12a12, and the size of the light-emitting area of ​​the second light-emitting element 13b along the second direction Y is the length of the light-emitting area of ​​the second light-emitting element 13b. In this way, it is ensured that the two second light-emitting elements 13b can be arranged in the length direction of the second isolation opening 12a12.

[0142] Optionally, all the third light emitting elements 13c in the third isolation openings 12a13 are arranged at intervals along the second direction Y. In this way, all the third light emitting elements 13c in the third isolation openings 12a13 can be arranged more regularly, which is beneficial to improving the display effect.

[0143] Optionally, the sum of the sizes of the light-emitting areas of all the third light-emitting elements 13c in the third isolation opening 12a13 along the second direction Y is smaller than the size of the third isolation opening 12a13 along the second direction Y. Specifically, the size of the third isolation opening 12a13 along the second direction Y is the length of the third isolation opening 12a13, and the size of the light-emitting area of ​​the third light-emitting element 13c along the second direction Y is the length of the light-emitting area of ​​the third light-emitting element 13c. In this way, it is ensured that the two third light-emitting elements 13c can be arranged in the length direction of the third isolation opening 12a13.

[0144] Optionally, the size of the light-emitting area of ​​the first light-emitting element 13a along the second direction Y, the size of the light-emitting area of ​​the second light-emitting element 13b along the second direction Y, and the size of the light-emitting area of ​​the third light-emitting element 13c along the second direction Y are all equal. That is, the lengths of the light-emitting area of ​​the first light-emitting element 13a, the light-emitting area of ​​the second light-emitting element 13b, and the light-emitting area of ​​the third light-emitting element 13c are all equal. In this way, the space in the second direction Y of the display panel 10 can be fully utilized to the greatest extent, which is conducive to improving the aperture ratio.

[0145] It should be noted that the size of the light-emitting area of ​​the first light-emitting element 13a along the first direction X, the size of the light-emitting area of ​​the second light-emitting element 13b along the first direction X, and the size of the light-emitting area of ​​the third light-emitting element 13c along the first direction X may be equal or unequal, and the embodiment of the present application does not limit this. It is understandable that the designer can design the widths of the first light-emitting element 13a, the second light-emitting element 13b, and the third light-emitting element 13c differently according to the difference in the lifespan of the light-emitting materials of the light-emitting elements 13 of different colors.

[0146] Optionally, the size of the first isolation opening 12a11 along the second direction Y, the size of the second isolation opening 12a12 along the second direction Y, and the size of the third isolation opening 12a13 along the second direction Y are all equal. That is, the length of the first isolation opening 12a11, the length of the second isolation opening 12a12, and the length of the third isolation opening 12a13 are all equal. In this way, the space in the second direction Y of the display panel 10 can be fully utilized to the greatest extent, which is conducive to improving the aperture ratio.

[0147] It should be noted that the length of the first isolation opening 12a11, the length of the second isolation opening 12a12, and the length of the third isolation opening 12a13 may be equal or unequal, and the embodiment of the present application does not limit this. It is understandable that the length of the first isolation opening 12a11 can be adaptively adjusted according to the length of the first light-emitting element 13a, the length of the second isolation opening 12a12 can be adaptively adjusted according to the length of the second light-emitting element 13b, and the length of the third isolation opening 12a13 can be adaptively adjusted according to the length of the third light-emitting element 13c.

[0148] In one embodiment, referring to Figure 5 and Figure 6 As shown, a plurality of isolation opening groups 12a are arranged in a plurality of rows along a first direction X, and the first direction X is perpendicular to the thickness direction of the array substrate 11. In the figure, h represents a row of isolation opening groups 12a. In this way, the isolation opening groups 12a can be arranged more regularly, which is conducive to improving the display effect.

[0149] In one embodiment, in any two adjacent rows of isolation opening groups 12a, all isolation opening groups 12a in one row of isolation opening groups 12a are arranged one by one with all isolation opening groups 12a in another row of isolation opening groups 12a along the second direction Y; the second direction Y intersects the first direction X, and the second direction Y is perpendicular to the thickness direction of the array substrate 11. In one example, the second direction Y is perpendicular to the first direction X. Here, the two isolation opening groups 12a are arranged relatively along the second direction Y, which means that, viewed from the second direction Y, the two isolation opening groups 12a are aligned and there is no misalignment between the two.

[0150] The above arrangement is equivalent to arranging all the isolation opening groups 12a not only into multiple rows along the first direction X, but also into multiple columns along the second direction Y. In this way, the isolation opening groups 12a can be arranged more regularly, which is beneficial to improving the display effect.

[0151] Optionally, in any two adjacent rows of isolation opening groups 12a, all first isolation openings 12a11 in one row of isolation opening groups 12a are arranged one-to-one with all first isolation openings 12a11 in another row of isolation opening groups 12a along the second direction Y, that is, each first isolation opening 12a11 in one row of isolation opening groups 12a corresponds to a first isolation opening 12a11 in another row of isolation opening groups 12a, and when viewed along the second direction Y, the two corresponding first isolation openings 12a11 are aligned without misalignment. In this way, the first isolation openings 12a11 can be arranged more regularly, which is conducive to improving the display effect.

[0152] In one example, all the first isolation openings 12 a 11 are not only arranged in a plurality of rows along the first direction X, but also arranged in a plurality of columns along the second direction Y.

[0153] Optionally, in any two adjacent rows of isolation opening groups 12a, all the second isolation openings 12a12 in one row of isolation opening groups 12a are relatively arranged one-to-one with all the second isolation openings 12a12 in another row of isolation opening groups 12a along the second direction Y. The relative arrangement here has the same meaning as the relative arrangement in the previous text, and will not be repeated here. In this way, the second isolation openings 12a12 can be arranged more regularly, which is conducive to improving the display effect.

[0154] In one example, all the second isolation openings 12 a 12 are not only arranged in a plurality of rows along the first direction X, but also arranged in a plurality of columns along the second direction Y.

[0155] Optionally, in any two adjacent rows of isolation opening groups 12a, all the third isolation openings 12a13 in one row of isolation opening groups 12a are relatively arranged one by one with all the third isolation openings 12a13 in another row of isolation opening groups 12a along the second direction Y. The relative arrangement here has the same meaning as the relative arrangement in the previous text, and will not be repeated here. In this way, the third isolation openings 12a13 can be arranged more regularly, which is conducive to improving the display effect.

[0156] In one example, all the third isolation openings 12 a 13 are not only arranged in a plurality of rows along the first direction X, but also arranged in a plurality of columns along the second direction Y.

[0157] In one embodiment, referring to Figure 1 and Figure 2 As shown in FIG. 1 , the distance between the light emitting areas of the two first light emitting elements 13a in the same first isolation opening 12a11 is S1. Figure 3 and Figure 4As shown, in two adjacent isolation opening groups 12a along the second direction Y, the minimum distance between the light emitting area of ​​the first light emitting element 13a in the upper first isolation opening 12a11 and the first light emitting element 13a in the lower first isolation opening 12a11 is S2. S2 is greater than S1.

[0158] Reference Figure 5 As shown, all the first light emitting elements 13a are arranged in multiple rows along the first direction X. The distance between the light emitting area of ​​the first light emitting element 13a in the first row and the light emitting area of ​​the first light emitting element 13a in the second row is S1, and the distance between the light emitting area of ​​the first light emitting element 13a in the second row and the light emitting area of ​​the first light emitting element 13a in the third row is S2.

[0159] All the second light emitting elements 13b are arranged in multiple rows along the first direction X. The distance between the light emitting area of ​​the first row of second light emitting elements 13b and the light emitting area of ​​the second row of second light emitting elements 13b is S1, and the distance between the light emitting area of ​​the second row of second light emitting elements 13b and the light emitting area of ​​the third row of second light emitting elements 13b is S2.

[0160] All the third light emitting elements 13c are arranged in multiple rows along the first direction X. The distance between the light emitting area of ​​the first row of third light emitting elements 13c and the light emitting area of ​​the second row of third light emitting elements 13c is S1, and the distance between the light emitting area of ​​the second row of third light emitting elements 13c and the light emitting area of ​​the third row of third light emitting elements 13c is S2.

[0161] In one embodiment, referring to Figure 7 As shown, in any two adjacent rows of isolation opening groups 12a, all isolation opening groups 12a in one row of isolation opening groups 12a are arranged in a staggered manner with all isolation opening groups 12a in another row of isolation opening groups 12a along the second direction Y. That is, from the second direction Y, all isolation opening groups 12a in one row are staggered (offset) with all isolation opening groups 12a in another row. In one example, each isolation opening group 12a has a center line parallel to the second direction Y, the center lines of all isolation opening groups 12a in odd rows are arranged at intervals along the first direction X, the center lines of all isolation opening groups 12a in even rows are also arranged at intervals along the first direction X, and the center line of each isolation opening group 12a in the even rows is located between the center lines of two adjacent isolation opening groups 12a in the odd rows. In this way, it is helpful to improve the problem of different spacings between light-emitting areas of light-emitting elements 13 in different rows.

[0162] Optionally, in any two adjacent rows of isolation opening groups 12a, all first isolation openings 12a11 in one row of isolation opening groups 12a are staggered with all first isolation openings 12a11 in another row of isolation opening groups 12a along the second direction Y. The staggered arrangement here has the same meaning as the staggered arrangement in the previous text and will not be repeated here.

[0163] Optionally, in any two adjacent rows of isolation opening groups 12a, all second isolation openings 12a12 in one row of isolation opening groups 12a are staggered with all second isolation openings 12a12 in another row of isolation opening groups 12a along the second direction Y. The staggered arrangement here has the same meaning as the staggered arrangement in the previous text and will not be repeated here.

[0164] Optionally, in any two adjacent rows of isolation opening groups 12a, all third isolation openings 12a13 in one row of isolation opening groups 12a are staggered with all third isolation openings 12a13 in another row of isolation opening groups 12a along the second direction Y. The staggered arrangement here has the same meaning as the staggered arrangement in the previous text and will not be repeated here.

[0165] refer to Figure 7 As shown, in this embodiment, the first light emitting elements 13a of the first row and the first light emitting elements 13a of the second row are arranged in alignment (relatively arranged) in the second direction Y, and the first light emitting elements 13a of the second row and the first light emitting elements 13a of the third row are arranged in staggered arrangement in the second direction Y. In this way, from a macroscopic point of view, the problem of the large distance between the first light emitting elements 13a of the second row and the first light emitting elements 13a of the third row in the first direction X can be improved, thereby optimizing the problem of uneven distance between the first light emitting elements 13a in the first direction X and optimizing the display effect. The second light emitting element 13b and the third light emitting element 13c have the same effect, which will not be repeated here.

[0166] In one embodiment, referring to Figure 8 As shown, the plurality of isolation opening groups 12a are arranged in a plurality of rows along the second direction Y, and the second direction Y is perpendicular to the thickness direction of the array substrate 11. Figure 8 In FIG. 1 , L represents a column of isolated opening groups 12 a.

[0167] In any two adjacent columns of isolation opening groups 12a, all isolation opening groups 12a in one column of isolation opening groups 12a are arranged in a staggered manner with all isolation opening groups 12a in another column of isolation opening groups 12a along the first direction X. That is, when viewed from the first direction X, all isolation opening groups 12a in one column are arranged in a staggered manner with all isolation opening groups 12a in another column. This is conducive to improving the problem of uneven display in the row direction.

[0168] Optionally, all the first light emitting elements 13a are arranged in rows along the first direction X and in columns along the second direction Y; all the second light emitting elements 13b are arranged in rows along the first direction X and in columns along the second direction Y; all the third light emitting elements 13c are arranged in rows along the first direction X and in columns along the second direction Y.

[0169] Reference Figure 8 , taking the first light-emitting element 13a in the first row and the first light-emitting element 13a in the second row as examples, the distance between the light-emitting areas of the two first light-emitting elements 13a in the odd columns is S2, and the distance between the light-emitting areas of the two first light-emitting elements 13a in the even columns is S1. The distance between any two adjacent rows of first light-emitting elements 13a changes regularly. In this way, from a macroscopic point of view, the problem of obvious distance differences between the first light-emitting elements 13a in different rows can be overcome, and the display effect is optimized. The second light-emitting element 13b and the third light-emitting element 13c have the same effect, which will not be repeated here.

[0180] It should be noted that the arrangement of the pixel openings 14a is the same as the arrangement of the light emitting elements 13. Figure 2 As shown in FIG. 1 , when the distance between the light-emitting areas of two light-emitting elements 13 is S1, the distance between the two pixel openings 14a corresponding to the two light-emitting elements 13 is also S1. Here, the distance between the two pixel openings 14a refers to the distance between the bottom of one pixel opening 14a and the bottom of the other pixel opening 14a.
