Thereby, the color mixing effect between the adjacent first sub-pixel and the second sub-pixel is good, the color mixing effect between the adjacent third sub-pixel and the fourth sub-pixel is good, which is advantageous for improving the display effect of the display panel. Further, the light-emitting colors of the second sub-pixel and the fourth sub-pixel are the same, and the light-emitting colors are different from those of the first sub-pixel and the third sub-pixel. Since the adjacent second sub-pixel and the fourth sub-pixel are separated by the intervention of the first sub-pixel or the third sub-pixel, as can be understood, in the same repeating unit, the first sub-pixel, the second sub-pixel and the third sub-pixel are arranged adjacent to each other, or the first sub-pixel, the fourth sub-pixel and the third sub-pixel are arranged adjacent to each other, and the adjacent first sub-pixel and the second sub-pixel, the adjacent third sub-pixel and the fourth sub-pixel are arranged compactly. Therefore, with this pixel arrangement structure, the aperture ratio of the display panel having the pixel arrangement structure can be improved, and the display effect of the display panel can also be improved.Also, for example, both the first sub-pixel and the third sub-pixel adjacent to the second sub-pixel in the first direction have a structure in which a part thereof surrounds the second sub-pixel. Therefore, the color mixing effect between the first sub-pixel and the second sub-pixel arranged adjacent to each other, and the color mixing effect between the second sub-pixel and the third sub-pixel arranged adjacent to each other can be improved, which is advantageous for improving the display effect of the display panel. The structure is such that the adjacent first sub-pixel and third sub-pixel are separated by the intervention of one second sub-pixel, and the emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel are different. By combining these, the color mixing effect of the pixel unit composed of the first sub-pixel, the second sub-pixel, and the third sub-pixel is improved. Also, in the pixel unit, the arrangement of the first sub-pixel, the second sub-pixel, and the third sub-pixel is compact.

Embodiments for Carrying out the Invention

[0030] In order to more clearly understand the above objects, features, and advantages of the present application, the following will describe in detail the specific embodiments of the present application with reference to the drawings. For the present application to be fully understood, many specific details are described in the following description. However, the present application can be implemented in many aspects other than those described in this specification, and those skilled in the art can make similar improvements without departing from the idea of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] In the description of the present application, it should be understood that when terms such as "center", "longitudinal direction", "lateral direction", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial direction", "radial direction", "circumferential direction" exist, the orientation or positional relationship indicated by these terms is shown based on the drawings, and is only for the purpose of simplifying the description to make it easier to explain the present application, and does not mean or imply that the device or element mentioned must have a specific orientation and be structured and operated in a specific orientation, so it should not be construed as limiting the present application.

[0032] Also, when terms such as "first" and "second" exist, these terms are used for illustrative purposes only and should not be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first" and "second" can include at least one feature explicitly or implicitly. In the description of this application, when the term "a plurality" exists, "a plurality" means at least two, for example, two, three, etc., unless otherwise clearly defined.

[0033] In the description of this application, when terms such as "attach", "connect", "couple", "fix", etc. exist, these terms should be understood in a broad sense unless there are otherwise clear regulations and limitations. Unless otherwise clearly limited, for example, it may be a fixed connection, a detachable connection, or integrated. Also, it may be a mechanical connection or an electrical connection. Also, it may be directly connected or indirectly connected through an intermediate medium, or it may be the internal communication between two elements or the interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific situation.

[0034] In this application, unless there are otherwise clear regulations and limitations, when there is a similar description that the first feature is "above" or "below" the second feature, the first feature and the second feature may be in direct contact, or the first feature and the second feature may be in indirect contact through an intermediate medium. Also, the fact that the first feature is "above", "upward", and "upper surface" of the second feature may only indicate that the first feature is directly above or obliquely above the second feature, or that the horizontal height of the first feature is greater than that of the second feature. The fact that the first feature is "below", "downward", and "lower surface" of the second feature may only indicate that the first feature is directly below or obliquely below the second feature, or that the horizontal height of the first feature is smaller than that of the second feature.

[0035] It should be noted that when one element is said to be "fixed to" or "provided on" another element, it may be directly disposed on the other element or there may be intervening elements. When one element is considered to be "connected to" another element, it may be directly connected to the other element or there may be intervening elements. If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this specification are for illustrative purposes only and do not represent the only embodiments.

[0036] As described in the background art, improving the aperture ratio is one of the future development trends of OLED display panels. In the manufacturing process of sub-pixels of conventional display panels, a fine metal mask (FMM) is mainly used to deposit organic light-emitting materials on a substrate through a plurality of apertures of the fine metal mask. In order to ensure the product yield, most manufacturers set the dimensions of the apertures of the fine metal mask to be larger than the dimensions of the pixel apertures and make the intervals between the apertures of the fine metal mask equal. In this way, the intervals between adjacent sub-pixels are equal, and the improvement of the aperture ratio of the OLED display panel is also limited.

[0037] In the related art, by forming a separation structure for separating adjacent sub-pixels on a substrate, in the process of forming sub-pixels by a vapor deposition method, an expensive fine metal mask (FMM) can be made unnecessary, and the manufacturing cost of the OLED display panel can be reduced.

[0038] Due to the separation structure in the related art, the design of sub-pixels is no longer limited to the fine metal mask (FMM). Based on this, the present application designs a pixel array structure, a display panel, and a display device that can improve the display effect of the display panel while improving the aperture ratio of the OLED display panel.

[0039] FIG. 1 shows a schematic structural diagram of a pixel array structure in an embodiment of the present application, and FIG. 2 shows a partial enlarged schematic diagram of FIG. 1.

[0040] According to the present application, a pixel array structure is provided. Referring to FIGS. 1 and 2 and also referring to FIGS. 3 to 8 together, the pixel array structure provided in an embodiment of the present application includes a plurality of repeating units 100. Each repeating unit 100 includes an adjacent first sub-pixel group and a second sub-pixel group. The first sub-pixel group includes a first sub-pixel 110 and a second sub-pixel 120. A part of the light-emitting region of the first sub-pixel 110 surrounds the light-emitting region of the second sub-pixel 120. The second sub-pixel group includes a third sub-pixel 130 and a fourth sub-pixel 140. A part of the light-emitting region of the third sub-pixel 130 surrounds the light-emitting region of the fourth sub-pixel 140.

[0041] The light-emitting colors of the second sub-pixel 120 and the fourth sub-pixel 140 are the same, and are different from the light-emitting colors of the first sub-pixel 110 and the third sub-pixel 130. This means that the light-emitting colors of the first sub-pixel 110 and the second sub-pixel 120 are different, and the light-emitting colors of the third sub-pixel 130 and the second sub-pixel 120 are different. On the other hand, the light-emitting colors of the first sub-pixel 110 and the third sub-pixel 130 may be the same or different.

[0042] The specific light-emitting colors of the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 can be selected according to factors such as device requirements, sub-pixel area, and manufacturing process, and are not particularly limited.

[0043] The emission colors of the first sub-pixel 110 and the second sub-pixel 120 are different, and the emission colors of the third sub-pixel 130 and the second sub-pixel 120 are different. Also, since the adjacent second sub-pixel 120 and fourth sub-pixel 140 are separated by the intervention of the first sub-pixel 110 or the third sub-pixel 130, in the same repeating unit 100, one pixel unit is formed by arranging the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 adjacent to each other, or one pixel unit is formed by arranging the first sub-pixel 110, the fourth sub-pixel 140, and the third sub-pixel 130 adjacent to each other. In two adjacent repeating units 100, since there is a case where two adjacent pixel units share the first sub-pixel 110 or the third sub-pixel 130, the aperture ratio of the display panel 10 including this pixel array structure can be improved. Also, in the same repeating unit 100, since a part of the light-emitting region of the first sub-pixel 110 surrounds the light-emitting region of the second sub-pixel 120, and a part of the light-emitting region of the third sub-pixel 130 surrounds the light-emitting region of the fourth sub-pixel 140, the color mixing effect of the pixel unit composed of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 arranged adjacent to each other, or the pixel unit composed of the first sub-pixel 110, the fourth sub-pixel 140, and the third sub-pixel 130 arranged adjacent to each other is good, which is advantageous for improving the display effect of the display panel 10. Therefore, with this pixel array structure, the aperture ratio of the display panel 10 can be improved while improving the display effect of the display panel 10.

[0044] In some embodiments, a plurality of repeating units 100 are arranged in an array.

[0045] In a plurality of repeating units 100 arranged in an array, a plurality of pixel units that repeat can be formed, and the color mixing effect of each pixel unit is good, which is advantageous for improving the aperture ratio of the display panel 10 and also advantageous for improving the display effect of the display panel 10.

[0046] In some embodiments, a plurality of repeating units 100 are in the first direction F 1and the first direction F 1 and the second direction F intersecting with it 2 are arranged in an array. That is, a plurality of repeating units 100 are arranged in rows in the first direction F 1 and are arranged in columns in the second direction F intersecting with the first direction F 1 and the second direction F intersecting with it 2 are arranged in columns.

[0047] In this way, in the first direction F 1 in the same row, one pixel unit is formed by arranging the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 adjacent to each other in the first direction F 1 or one pixel unit is formed by arranging the first sub-pixel 110, the fourth sub-pixel 140, and the third sub-pixel 130 adjacent to each other in the first direction F 1 and there exists a situation where two adjacent pixel units in the same row share the first sub-pixel 110 or the third sub-pixel 130. Also, combined with the fact that a plurality of repeating units 100 are arranged in columns in the second direction F 2 in this pixel array structure, a plurality of repeating pixel units can be formed, and since the color mixing effect of each pixel unit is good, it is advantageous for improving the aperture ratio of the display panel 10 and also advantageous for improving the display effect of the display panel 10.

[0048] Optionally, the first direction F 1 and the second direction F 2 are perpendicular to each other. As an example, one of the first direction F 1 and the second direction F 2 is parallel to the longitudinal direction of the display panel 10, and the other of the first direction F 1 and the second direction F 2 is parallel to the width direction of the display panel 10.

[0049] In some embodiments, referring to FIGS. 1 to 4, the adjacent repeating units 100 in two adjacent rows are arranged in a staggered manner, that is, the adjacent repeating units 100 in two adjacent rows are in the first direction F 1They are arranged offset along

[0050] Thus, it is possible to improve the problems of color edges, stripe patterns, and jaggedness that occur due to all the sub-pixels in the same column having the same emission color, which is advantageous for reducing the color edge problem, stripe pattern, and jaggedness of the display screen, and can improve the display effect of the display panel 10.

[0051] In some embodiments, the first sub-pixel group and the second sub-pixel group in the repeating unit 100 are arranged adjacent to each other in the first direction F 1 next to each other.

The light-emitting region of the first sub-pixel 110 includes a 13th pixel side 1104. In adjacent first sub-pixel 110 and second sub-pixel 120, the 12th pixel side 1204 and the 13th pixel side 1104 are on the same line.

[0113] Optionally, in the first sub-pixel 110 and the second sub-pixel 120 in the same row, the 12th pixel side 1204 and the 13th pixel side 1104 are on the same line.

[0114] As can be understood, in the first direction F 1 in the second direction F of the first sub-pixel group 2 the dimension along is kept constant, whereby the arrangement space of the display panel 10 can be fully utilized, which is advantageous for improving the aperture ratio of the display panel 10.

[0115] In some embodiments, as shown in FIGS. 1-2 and FIGS. 5-6, the light-emitting region of the fourth sub-pixel 140 further includes a 14th pixel side 1404 arranged in parallel on the opposite side of the third pixel side 1401. The light-emitting region of the third sub-pixel 130 includes a 15th pixel side 1304. In adjacent third sub-pixel 130 and fourth sub-pixel 140, the 14th pixel side 1404 and the 15th pixel side 1304 are on the same line.

[0116] Optionally, in the third sub-pixel 130 and the fourth sub-pixel 140 in the same row, the 14th pixel side 1404 and the 15th pixel side 1304 are on the same line.

[0117] As can be understood, in the first direction F 1 in the second direction F of the second sub-pixel group 2 the dimension along is kept constant, whereby the arrangement space of the display panel 10 can be fully utilized, which is advantageous for improving the aperture ratio of the display panel 10.

[0118] In this embodiment, in the first sub-pixel group and the second sub-pixel group in the same row, the 12th pixel side 1204, the 13th pixel side 1104, the 14th pixel side 1404, and the 15th pixel side 1304 are on the same line.

[0119] In this way, the first sub-pixel group and the second sub-pixel group in the same row are arranged flush along two sides in the second direction F 2 , thereby making it possible to fully utilize the arrangement space of the display panel 10, which is advantageous for improving the aperture ratio of the display panel 10.

[0120] In some embodiments, the area of the light-emitting region of the first sub-pixel 110 is greater than or equal to the area of the light-emitting region of the third sub-pixel 130.

[0121] The relative relationship between the area of the light-emitting region of the first sub-pixel 110 and the area of the light-emitting region of the third sub-pixel 130 can be selected according to factors such as the emission color of the first sub-pixel 110, the emission color of the third sub-pixel 130, device requirements, and manufacturing processes. It may be selected such that the area of the light-emitting region of the first sub-pixel 110 is larger than the area of the light-emitting region of the third sub-pixel 130, or it may be selected such that the area of the light-emitting region of the first sub-pixel 110 is equal to the area of the light-emitting region of the third sub-pixel 130, and it is not particularly limited here.

[0122] In some other embodiments, since the emission colors of the second sub-pixel 120 and the fourth sub-pixel 140 are the same, the area of the light-emitting region of the second sub-pixel 120 is equal to the area of the light-emitting region of the fourth sub-pixel 140. As an example, the second sub-pixel 120 and the fourth sub-pixel 140 may be provided as sub-pixels of a color sensitive to the human eye, such as a green sub-pixel, which is advantageous for improving the resolution of the display panel 10 and can also make the display of the display panel 10 more uniform.

[0123] In some other embodiments, the area of the light-emitting region of the first sub-pixel 110 is greater than or equal to the area of the light-emitting region of the third sub-pixel 130, and the area of the light-emitting region of the second sub-pixel 120 is equal to the area of the light-emitting region of the fourth sub-pixel 140.

[0124] Optionally, referring to FIG. 2, FIG. 4, FIG. 6 and FIG. 8, the area of ​​the light emitting region of the first sub-pixel 110 is larger than the area of ​​the light emitting region of the third sub-pixel 130, and the light emitting region of the first sub-pixel 110 is extended in the first direction F. 1 a first sub-light-emitting region 110a extending in a second direction F; 2 The light-emitting region of the third sub-pixel 130 extends in the first direction F. 1 a third sub-light-emitting region 130a extending in the second direction F; 2 and a fourth sub-light-emitting region 130b extending in the second direction F of the first sub-light-emitting region 110a. 2 The dimension in the second direction F of the third sub-light-emitting region 130a is 2 The dimension of the second sub-light-emitting region 110b in the first direction is greater than the dimension of the fourth sub-light-emitting region 130b in the first direction.

[0125] When the lifetime of the first sub-pixel 110 is low, the lifetimes of the second sub-pixel 120 and the fourth sub-pixel 140 are next low, and the lifetime of the third sub-pixel 130 is high, the dimension of the second sub-light-emitting region 110b in the first direction is larger than the dimension of the fourth sub-light-emitting region 130b in the first direction and the dimension of the first sub-light-emitting region 110a in the second direction F is larger than the dimension of the fourth sub-light-emitting region 130b in the first direction. 2 The dimension in the second direction F of the third sub-light-emitting region 130a is 2 In this way, the area of ​​the light-emitting region of the first sub-pixel 110 can be increased to a certain extent, and the area of ​​the light-emitting region of the third sub-pixel 130 can be decreased to a certain extent, thereby achieving a good balance between the overall lifetimes of the first sub-pixel 110 and the third sub-pixel 130, and thereby improving the lifetime of the display panel 10.

[0126] In addition, the first sub-light-emitting region 110a in the second direction F 2 and the dimension in the second direction F of the third sub-light-emitting region 130a. 2 Since the dimensions in the second direction F of the first sub-pixel 110 and the third sub-pixel 130 in the same row are equal, 2The dimensions in [a certain context] are equal, thereby enabling the sufficient utilization of the arrangement space of the display panel 10, which is advantageous for improving the aperture ratio of the display panel 10.

[0127] In some embodiments, in four adjacent sub-pixel groups in two adjacent rows, a quadrilateral is formed by a line connecting the centers of two second sub-pixels 120 and the centers of two fourth sub-pixels 140, and the quadrilateral has a first side L1 and a second side L2 arranged opposite to the second direction F 2 and a third side L3 and a fourth side L4 arranged opposite to the first direction F 1 where at least one of the first side L1 and the second side L2 is parallel to the first direction F 1

[0128] That is, the first side L1 may be parallel to the first direction F 1 or the second side L2 may be parallel to the first direction F 1 or both the first side L1 and the second side L2 may be parallel to the first direction F 1

[0129] As an example, as shown in FIGS. 1 to 8, both the first side L1 and the second side L2 are parallel to the first direction F 1

[0130] As can be understood, the line connecting the centers of the second sub-pixels 120 and the fourth sub-pixels 140 located in the same row is a straight line. In this way, the wiring between the second sub-pixels 120 and the fourth sub-pixels 140 in the same row becomes easy, which is also advantageous for arranging the second sub-pixels 120 and the fourth sub-pixels 140 in the same row uniformly. To a certain extent, it is advantageous for sufficiently utilizing the arrangement space of the display panel 10 and for improving the aperture ratio of the display panel 10.

[0131] In some embodiments, the length of the first side L1 and the length of the second side L2 may be different.

[0132] ​​​The lengths of the third side L3 and the fourth side L4 may be equal. The lengths of the first side L1 and the second side L2 may be different, and the lengths of the third side L3 and the fourth side L4 may be equal (as shown in FIGS. 1 to 4, for example).

[0133] Optionally, the quadrilateral is a trapezoid. Specifically, the quadrilateral is an isosceles trapezoid.

[0134] Thus, in the four adjacent sub-pixel groups in two adjacent rows, the two second sub-pixels 120 and the two fourth sub-pixels 140 are arranged relatively uniformly, which is advantageous for making full use of the arrangement space of the display panel 10 to a certain extent and for improving the aperture ratio of the display panel 10.

[0135] In some other embodiments, the lengths of the first side L1 and the second side L2 may be equal. The lengths of the third side L3 and the fourth side L4 may be equal. Of course, the lengths of the first side L1 and the second side L2 may be equal, and the lengths of the third side L3 and the fourth side L4 may be equal (as shown in FIGS. 5 to 9, for example).

[0136] Thus, in the four adjacent sub-pixel groups in two adjacent rows, since the two second sub-pixels 120 and the two fourth sub-pixels 140 are arranged relatively uniformly, the plurality of second sub-pixels 120 and the plurality of fourth sub-pixels 140 are arranged relatively uniformly, which is advantageous for making full use of the arrangement space of the display panel 10 to a certain extent and for improving the aperture ratio of the display panel 10.

[0137] Optionally, the quadrilateral is a rectangle. Specifically, in the embodiment shown in FIG. 9, the quadrilateral is a square.

[0138] In this way, the plurality of second sub-pixels 120 and the plurality of fourth sub-pixels 140 are arranged relatively uniformly, which is advantageous for making full use of the arrangement space of the display panel 10 to a certain extent and for improving the aperture ratio of the display panel 10. If both the second sub-pixels 120 and the fourth sub-pixels 140 are green sub-pixels, the plurality of uniformly arranged green sub-pixels are also advantageous for improving the display effect of the display panel 10.

[0139] In some embodiments, both the second sub-pixels 120 and the fourth sub-pixels 140 are green sub-pixels, and since the emission colors of the first sub-pixels 110 and the third sub-pixels 130 are different, it is possible to better form one pixel unit with three different color sub-pixels, which is more advantageous for improving the display effect of the display panel 10.

[0140] Optionally, the first sub-pixel 110 is one of a blue sub-pixel and a red sub-pixel, and the third sub-pixel 130 is the other of the blue sub-pixel and the red sub-pixel.

[0141] Specifically, the first sub-pixel 110 is a blue sub-pixel, and the third sub-pixel 130 is a red sub-pixel.

[0142] The red sub-pixel, the green sub-pixel, and the blue sub-pixel constitute the three primary colors of the color display of the display panel 10, and the color display of the display panel 10 can be realized.

[0143] Optionally, the emission area of the blue sub-pixel is larger than the emission area of the red sub-pixel and larger than the emission area of the green sub-pixel.

[0144] In this way, the overall lifetimes of the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 can be well balanced, and thus the lifetime of the display panel 10 can be improved.

[0145] According to the present application, a display panel 10 having the pixel arrangement structure of any of the above-described embodiments is provided.

[0146] Alternatively, referring to FIG. 10, the display panel 10 further includes a substrate 210 and a separation structure 300. The plurality of repeating units 100 and the separation structure 300 are both disposed on the substrate 210 (in FIG. 10, the fourth sub-pixel 140 is not shown). The separation structure 300 is for separating adjacent repeating units 100, and for separating between two adjacent ones of the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 within the same repeating unit 100.

[0147] The separation structure 300 is used to separate between two adjacent pixel materials among the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140. Thus, in the process of forming the plurality of repeating units 100 by vapor deposition, an expensive fine metal mask (FMM) can be made unnecessary. Therefore, the structural design of the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 is not limited to the fine metal mask (FMM), and the separation structure 300, the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 can be designed according to the requirement of improving the aperture ratio of the display panel 10, which is advantageous for improving the aperture ratio of the display panel 10 and can reduce the manufacturing cost of the display panel 10.

[0148] In some embodiments, the outer contour of the projection of the upper surface of the separation structure 300 onto the substrate 210 is located on the outer periphery of the projection of the lower surface of the separation structure 300 onto the substrate 210.

[0149] Specifically, the separation structure 300 includes a first separation portion 310 and a second separation portion 320 stacked and disposed on the substrate 210. The outer contour of the projection of the second separation portion 320 onto the substrate 210 is located on the outer periphery of the projection of the corresponding first separation portion 310 onto the substrate 210.

[0150] Alternatively, the width of the lower surface of the second separation portion 320 is larger than the width of the upper surface of the first separation portion 310. Here, the width means the distance between the side closer to the sub-pixels of one color in the separation structure 300 and the side closer to the sub-pixels of the other color in the separation structure 300.

[0151] Thus, the separation structure 300 is for separating the pixel materials of adjacent sub-pixels in the repeating unit 100 during vapor deposition. When manufacturing the display panel 10, the separation effect of the separation structure 300 on the pixel materials corresponding to the sub-pixels of the repeating unit 100 and the sealing materials corresponding to the sealing means 400 can be enhanced, which is advantageous for forming the separation structure 300 that can realize a complete sealing structure for the sub-pixels of the repeating unit 100.

[0152] In some embodiments, the display panel 10 further includes a pixel defining layer 220 disposed on the substrate 210.

[0153] The material of the pixel defining layer 220 may be polyimide, acrylic, polyethylene terephthalate, etc., and the shape of the orthographic projection of the pixel opening 2201 on the substrate 210 may be rectangular, trapezoidal, etc.

[0154] The first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 all include a first electrode 101, a light-emitting region 102, and a second electrode 103 that are stacked and arranged. The pixel defining layer 220 is provided with a plurality of pixel openings 2201 that at least partially expose the first electrode 101. The light-emitting region 102 and the second electrode 103 are provided in the corresponding pixel openings 2201. The separation structure 300 defines a plurality of first openings 301 corresponding to the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140. The plurality of pixel openings 2201 communicate with the corresponding plurality of first openings 301.

[0155] Specifically, the first electrode 101 is an anode and the second electrode 103 is a cathode.

[0156] Specifically, the plurality of pixel apertures 2201 can communicate with the plurality of first apertures 301 in a one-to-one correspondence.

[0157] Here, the substrate 210 may be an array substrate including a stacked base material, a driving array layer, and a planarizing layer. The base material may be a flexible polyimide (PI), a rigid glass, a thin metal sheet, or the like. In the embodiments of the present application, although the base materials of other materials are not described in detail, those skilled in the art can select each type of material according to actual needs.

[0158] It should be noted that the separation structure 300 may be provided directly on the substrate 210 or indirectly on the substrate 210. For example, the pixel defining layer 220 may be provided on the substrate 210, and the separation structure 300 may be provided on the pixel defining layer 220.

[0159] In some embodiments, the display panel 10 further includes a plurality of sealing means 400 that are arranged in a one-to-one correspondence within the plurality of first apertures 301 and completely cover the corresponding first sub-pixel 110, the corresponding second sub-pixel 120, the corresponding third sub-pixel 130, or the corresponding fourth sub-pixel 140.

[0160] The material of the sealing means 400 can include at least one of an organic material and an inorganic material.

[0161] The sealing means 400 can block the entry of moisture into the first sub-pixel 110, the corresponding second sub-pixel 120, the corresponding third sub-pixel 130, or the corresponding fourth sub-pixel 140, thereby forming an independent seal for the first sub-pixel 110, the corresponding second sub-pixel 120, the corresponding third sub-pixel 130, or the corresponding fourth sub-pixel 140, which is advantageous for improving the reliability of the display panel 10. On the other hand, the second electrode 103 can contact and be electrically connected to the adjacent separation structure 300. Through the separation structure 300, it becomes easy to supply a predetermined potential to the second electrodes 103 of the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140.

[0162] In some embodiments, the display panel 10 is disposed on the separation structure 300 and further includes a sealing layer 500 covering the plurality of sealing means 400.

[0163] The material of the sealing layer 500 can include at least one of an organic material and an inorganic material.

[0164] The sealing layer 500 corresponds to the overall sealing structure and is used to seal all of the first sub-pixels 110, all of the second sub-pixels 120, all of the third sub-pixels 130, all of the fourth sub-pixels 140, and all of the sealing means 400.

[0165] The combination of the sealing layer 500 and the sealing means 400 has the effect of doubly sealing the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140, improving the moisture blocking ability, and improving the reliability of the display panel 10.

[0166] As shown in FIGS. 11 and 12, according to the present application, a pixel array structure including a plurality of sub-pixels is provided, and the plurality of sub-pixels include a first sub-pixel 110, a second sub-pixel 120, and a third sub-pixel 130 that emit light of different colors. The first sub-pixel 110 and the third sub-pixel 130 are 1 alternately arranged in the first direction F, and the adjacent first sub-pixel 110 and third sub-pixel 130 are separated by the intervention of one second sub-pixel 120. The first sub-pixel 110 and the third sub-pixel 130 adjacent to the second sub-pixel 120 in the first direction F 1 both have a structure in which a part thereof surrounds the second sub-pixel 120.

[0167] In this way, the color mixing effect between the first sub-pixel 110 and the second sub-pixel 120 arranged adjacent to each other and the color mixing effect between the second sub-pixel 120 and the third sub-pixel 130 arranged adjacent to each other can be improved, which is advantageous for improving the display effect of the display panel 10. Since the adjacent first sub-pixel 110 and third sub-pixel 130 are separated by the intervention of one second sub-pixel 120 and the emission colors of the first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130 are different, the color mixing effect of the pixel unit composed of the first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130 is good. Also, in the pixel unit, the arrangement of the first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130 is compact. Therefore, with this pixel array structure, the aperture ratio of the display panel 10 including this pixel array structure can be improved, and the display effect of the display panel 10 can also be improved.

[0168] In some embodiments, the light-emitting region of the first sub-pixel 110 has a third recess that opens toward the adjacent second sub-pixel 120, and the light-emitting region of the third sub-pixel 130 has a fourth recess that opens toward the adjacent second sub-pixel 120. In the adjacent first sub-pixel 110 and third sub-pixel 130, a third accommodation space C is defined by the third recess and the adjacent fourth recess, and the third accommodation space C is for accommodating the second sub-pixel 120 between the adjacent first sub-pixel 110 and third sub-pixel 130.

[0169] In this way, the structure in which a part of the first sub-pixel 110 surrounds and arranges the adjacent second sub-pixel 120 and the structure in which a part of the third sub-pixel 130 surrounds and arranges the adjacent second sub-pixel 120 can enhance the color mixing effect of the sequentially adjacent first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130, and can make the arrangement of the sequentially adjacent first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130 more compact, which is also advantageous for making full use of the arrangement space of the display panel 10 and is advantageous for improving the aperture ratio of the display panel 10.

[0170] In some embodiments, the third recess has a fifth boundary 1105 parallel to the first direction F 1 and the fourth recess has a sixth boundary 1305 parallel to the first direction F 1 The light-emitting region of the second sub-pixel 120 includes a fifth pixel side 1205 adjacent to the fifth boundary 1105 and the sixth boundary 1305 respectively. The sixth boundary 1305 and the fifth boundary 1105 are on the same line and both are parallel to the fifth pixel side 1205.

[0171] In this way, the sixth boundary 1305 and the fifth boundary 1105 are arranged flush, and the intervals between the fifth pixel side 1205 adjacent to the sixth boundary 1305 and the fifth pixel side 1205 adjacent to the fifth boundary 1105 are made equal and arranged at equal intervals. Therefore, it is advantageous for reducing the difficulty of the manufacturing processes of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130, and is also advantageous for making full use of the arrangement space of the display panel 10 and for improving the aperture ratio of the display panel 10.

[0172] In this embodiment, the third recess further has a seventh boundary 1106 parallel to a second direction F 1 intersecting the first direction F 2 The fourth recess further has an eighth boundary 1306 parallel to the second direction F 2 The light-emitting region of the second sub-pixel 120 further includes a sixth pixel side 1206 adjacent to the seventh boundary 1106, and the sixth pixel side 1206 is parallel to the seventh boundary 1106. The light-emitting region of the second sub-pixel 120 further includes a seventh pixel side 1207 adjacent to the eighth boundary 1306 and disposed on the opposite side of the sixth pixel side 1206, and the seventh pixel side 1207 is parallel to the eighth boundary 1306.

[0173] Optionally, the first direction F 1 and the second direction F 2 are perpendicular to each other.

[0174] In this way, since the distance between the sixth pixel side 1206 and the seventh boundary 1106 can be arranged to be equally spaced, it is advantageous for reducing the difficulty of the manufacturing process of the first sub-pixel 110 and the second sub-pixel 120. Also, since the distance between the seventh pixel side 1207 and the eighth boundary 1306 can be arranged to be equally spaced, it is advantageous for reducing the difficulty of the manufacturing process of the second sub-pixel 120 and the third sub-pixel 130, and is also advantageous for making full use of the arrangement space of the display panel 10, and is advantageous for improving the aperture ratio of the display panel 10.

[0175] In this embodiment, the third recess includes two fifth boundaries 1105 arranged at intervals in the second direction F 2 and a seventh boundary 1106 connecting the two fifth boundaries 1105. The light-emitting region of the second sub-pixel 120 includes two fifth pixel sides 1205 arranged at intervals in the second direction F 2 and a sixth pixel side 1206 and a seventh pixel side 1207 connecting the two fifth pixel sides 1205.

[0176] Thereby, in the first sub-pixel 110, more adjacent second sub-pixels 120 can be surrounded, and the color mixing effect between the first sub-pixel 110 and the second sub-pixel 120 can be improved, which is also advantageous for improving the display effect of the display panel 10.

[0177] In this embodiment, the fourth recess includes two sixth boundaries 1305 arranged at intervals in the second direction F 2 and an eighth boundary 1306 connecting the two sixth boundaries 1305.

[0178] Thereby, in the third sub-pixel 130, more adjacent second sub-pixels 120 can be surrounded, and the color mixing effect between the second sub-pixel 120 and the third sub-pixel 130 can be improved, which is also advantageous for improving the display effect of the display panel 10.

[0179] In some embodiments, referring to FIG. 11, the first sub-pixel 110 and the third sub-pixel 130 are in a second direction F 1 intersecting the first direction F 2They are arranged in a row along

[0180] In this way, it is possible to improve the problems of color edges, stripe patterns, and jaggedness caused by all sub-pixels in the same column having the same emission color, which is beneficial for reducing color edge problems, stripe patterns, and jaggedness on the display screen, and can improve the display effect of the display panel 10.

[0181] In some other embodiments, referring to FIG. 12, the first sub-pixel 110 is arranged in a row along a second direction F 1 intersecting the first direction F 2 and the third sub-pixel 130 is arranged in a row along the second direction F 2 They are arranged in a row along.

[0182] The wiring of all the first sub-pixels 110 in the same column becomes easy, and the wiring of all the third sub-pixels 130 in the same column also becomes easy. On the other hand, a plurality of sub-pixels can be arranged relatively uniformly, which is beneficial for making full use of the arrangement space of the display panel 10 to a certain extent and is beneficial for improving the aperture ratio of the display panel 10.

[0183] In some embodiments, in the first direction F 1 the line connecting the centers of all the second sub-pixels 120 located in the same row is a straight line.

[0184] In this way, the wiring of the second sub-pixels 120 in the same row becomes easy, and it is also beneficial for arranging the second sub-pixels 120 in the same row uniformly. To a certain extent, it is beneficial for making full use of the arrangement space of the display panel 10 and is beneficial for improving the aperture ratio of the display panel 10.

[0185] Optionally, in a second direction F 1 intersecting the first direction F 2 the line connecting the centers of all the second sub-pixels 120 located in the same column is a straight line.

[0186] In this way, the wiring of the second sub-pixels 120 in the same column is facilitated, and it is also advantageous to arrange the second sub-pixels 120 in the same column uniformly.
