Combining that the adjacent first sub-pixel and the third sub-pixel are separated by a second sub-pixel, and the light-emitting colors of the first sub-pixel, the second sub-pixel and the third sub-pixel are different, the color mixing effect of the pixel unit composed of the first sub-pixel, the second sub-pixel and the third sub-pixel is better, and the arrangement of the first sub-pixel, the second sub-pixel and the third sub-pixel in this pixel unit is relatively compact. Thus, using this pixel arrangement structure can improve the aperture ratio of the display panel including this pixel arrangement structure while also improving the display effect of the display panel.

Detailed implementation manners

[0112] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0113] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0114] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "a plurality" appears, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0115] In this application, unless otherwise clearly specified and defined, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0116] In this application, unless otherwise clearly specified and defined, if there are descriptions such as a first feature being "on" or "under" a second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower horizontal level than the second feature.

[0117] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0118] 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 traditional display panels, fine metal mask plates (FMMs) are mainly used to evaporate organic light-emitting materials onto a substrate through multiple openings in the fine metal mask plates. To ensure the yield of products, most manufacturers set the size of the openings in the fine metal mask plates to be larger than the size of the pixel openings, and make the distances between the openings in the fine metal mask plates equal. In this way, the distances between adjacent sub-pixels are equal, which also limits the improvement of the aperture ratio of OLED display panels.

[0119] In the related art, an isolation structure for separating adjacent sub-pixels is formed on the substrate. In this way, during the process of forming sub-pixels by evaporation, the expensive fine metal mask plate (FMM) can be discarded, reducing the manufacturing cost of OLED display panels.

[0120] The isolation structure in the related art enables the design of sub-pixels to be no longer limited by the fine metal mask plate (FMM). Based on this, in order to improve the aperture ratio of OLED display panels, the present application designs a pixel arrangement structure, a display panel, and a display device, which can improve the aperture ratio of the display panel while also improving the display effect of the display panel.

The light-emitting region of the third sub-pixel 130 partially surrounds the light-emitting region of the fourth sub-pixel 140.

The light-emitting colors of the first sub-pixel 110 and the third sub-pixel 130 may be the same or different.

[0124] The specific emission 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 specifically limited herein.

[0125] Since 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, and considering that the adjacent second sub-pixel 120 and fourth sub-pixel 140 are separated by the first sub-pixel 110 or the third sub-pixel 130, therefore, in the same repeating unit 100, there are cases where the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are adjacent to each other and can form a pixel unit, or there are cases where the first sub-pixel 110, the fourth sub-pixel 140, and the third sub-pixel 130 are adjacent to each other and can form a pixel unit. In adjacent two repeating units 100, there are cases where two adjacent pixel units share the first sub-pixel 110 or the third sub-pixel 130. In this way, the aperture ratio of the display panel 10 including this pixel arrangement structure can be improved. And because in the same repeating unit 100, the light-emitting region of the first sub-pixel 110 partially surrounds the light-emitting region of the second sub-pixel 120, and the light-emitting region of the third sub-pixel 130 partially surrounds the light-emitting region of the fourth sub-pixel 140, the color mixing effect of the pixel unit composed of the adjacent first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130 is better, or the color mixing effect of the pixel unit composed of the adjacent first sub-pixel 110, fourth sub-pixel 140, and third sub-pixel 130 is better. Furthermore, it is beneficial to improve the display effect of the display panel 10. Therefore, by using this pixel arrangement structure, while improving the aperture ratio of the display panel 10, the display effect of the display panel 10 can also be improved.

[0126] In some embodiments, multiple repeating units 100 are arranged in an array.

[0127] In the multiple repeating units 100 arranged in an array, multiple repeating pixel units can be formed, and the color mixing effect of each pixel unit is better. Furthermore, it is beneficial to improve the aperture ratio of the display panel 10 while also being beneficial to improving the display effect of the display panel 10.

[0128] In some embodiments, multiple repeating units 100 are along the first direction F 1 and the second direction F 1 intersecting with the first direction F 2 are arranged in an array. That is, multiple repeating units 100 are arranged in rows along the first direction F 1 and are arranged in columns along the second direction F 1 intersecting with the first direction F 2

[0129] ​Thus, along the first direction F 1 , in the same row, the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are arranged adjacent to each other along the first direction F 1 , which can form a pixel unit, or the first sub-pixel 110, the fourth sub-pixel 140, and the third sub-pixel 130 are arranged adjacent to each other along the first direction F 1 , which can form a pixel unit, and in the same row, there is a situation where two adjacent pixel units share the first sub-pixel 110 or the third sub-pixel 130. Combining multiple repeating units 100 and the second direction F 2 are arranged in columns. Thus, using this pixel arrangement structure, multiple repeating pixel units can be formed, and the color mixing effect of each pixel unit is better. Furthermore, it is beneficial to improve the aperture ratio of the display panel 10 while also being beneficial to improving the display effect of the display panel 10.

[0130] Optionally, the first direction F 1 and the second direction F 2 are perpendicular to each other. Exemplarily, one of the first direction F 1 and the second direction F 2 is parallel to the length 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.

[0131] In some embodiments, referring to Figures 1 - 4 , the adjacent repeating units 100 in adjacent rows are arranged in a staggered manner, that is, the adjacent repeating units 100 in adjacent rows are arranged in a staggered manner along the first direction F 1 .

[0132] Thus, the problems of color fringes, stripe sense, and jagged sense caused by the sub-pixels of the same color in the same column can be improved, which is beneficial to reducing the color fringe problem, stripe sense, and jagged sense of the display screen, and thus can improve the display effect of the display panel 10.

[0133] 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 along the first direction F 1 .

[0134] Specifically, along the first direction F 1 , in two adjacent repeating units 100, a first sub-pixel group of one repeating unit 100 is adjacent to a second sub-pixel group of another repeating unit 100.

[0135] It can be understood that along the first direction F 1 , the first sub-pixel group and the second sub-pixel group are alternately arranged, along the first direction F 1, in the same row, there are a first sub-pixel 110, a second sub-pixel 120, and a third sub-pixel 130 arranged along a first direction F 1 adjacent to each other, which can form a pixel unit, or there are a first sub-pixel 110, a fourth sub-pixel 140, and a third sub-pixel 130 arranged along the first direction F 1 adjacent to each other, which can form a pixel unit, and in the same row, there is a situation where two adjacent pixel units share the first sub-pixel 110 or the third sub-pixel 130. Thus, using this pixel arrangement structure, multiple pixel units arranged in a row can be formed along the first direction F 1 Moreover, the color mixing effect of each pixel unit is relatively good. Furthermore, it is beneficial to improve the aperture ratio of the display panel 10 while also being beneficial to improving the display effect of the display panel 10.

[0136] In some embodiments, please refer to Figures 1 - 4 , along a second direction F 2 In two adjacent repeating units 100, the first sub-pixel group in one repeating unit 100 and the second sub-pixel group in the other repeating unit 100 are located in the same column.

[0137] In other words, the first sub-pixel group of the repeating unit 100 located in the Nth row and the second sub-pixel group of the repeating unit 100 located in the (N + 1)th row are arranged in the same column. The second sub-pixel group of the repeating unit 100 located in the Nth row and the first sub-pixel group of the repeating unit 100 located in the (N + 1)th row are arranged in the same column. Wherein, N > 0 and N is a natural number.

[0138] It can be understood that along the second direction F 2 , the first sub-pixel group and the second sub-pixel group are arranged alternately. Thus, on the one hand, along the first direction F 1 , in the same row, there are a first sub-pixel 110, a second sub-pixel 120, and a third sub-pixel 130 arranged along the first direction F 1 adjacent to each other, which can form a pixel unit, or there are a first sub-pixel 110, a fourth sub-pixel 140, and a third sub-pixel 130 arranged along the first direction F 1 adjacent to each other, which can form a pixel unit, and in the same row, there is a situation where two adjacent pixel units share the first sub-pixel 110 or the third sub-pixel 130. On the other hand, along the second direction F 2 , in the same column, there are a first sub-pixel 110, a second sub-pixel 120, and a third sub-pixel 130 arranged along the second direction F 2 adjacent to each other, which can form a pixel unit, or there are a first sub-pixel 110, a fourth sub-pixel 140, and a third sub-pixel 130 arranged along the second direction F 2Adjacent to each other, they can form a pixel unit, and in the same column, there are two adjacent pixel units sharing the first sub-pixel 110 or the third sub-pixel 130. Thus, using this pixel arrangement structure, a plurality of pixel units can be formed in rows along the first direction F 1 in rows and in columns along the second direction F 2 of a plurality of pixel units, and the color mixing effect of each pixel unit is relatively good. Furthermore, it is beneficial to improve the aperture ratio of the display panel 10 while also being beneficial to improving the display effect of the display panel 10.

[0139] In some embodiments, please refer to Figures 1 - 4 , along the first direction F 1 , the center connection line of the second sub-pixel 120 and the fourth sub-pixel 140 located in the same row is a straight line.

[0140] That is to say, along the first direction F 1 , the center connection lines of all the second sub-pixels 120 and all the fourth sub-pixels 140 located in the same row are straight lines.

[0141] Thus, it is convenient for the wiring of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row, and it is also beneficial to the uniform arrangement of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row. To a certain extent, it is beneficial to make full use of the arrangement space of the display panel 10, and thus it is beneficial to improve the aperture ratio of the display panel 10.

[0142] Specifically, in the embodiment shown in Figures 1 - 4 , along the second direction F 2 , the center connection line of the second sub-pixel 120 and the fourth sub-pixel 140 located in the same column is a broken line.

[0143] Thus, when the distance between adjacent sub-pixels is approximately the same, the arrangement space of the display panel 10 can be fully utilized, and thus it is beneficial to improve the aperture ratio of the display panel 10.

[0144] Of course, the present application is not limited to this. It can also be that, along the second direction F 2 , the center connection line of the second sub-pixel 120 and the fourth sub-pixel 140 located in the same column is a straight line.

[0145] That is to say, along the second direction F 2 , the center connection lines of all the second sub-pixels 120 and all the fourth sub-pixels 140 located in the same column are straight lines.

[0146] Thus, it is convenient for the wiring of the second sub-pixel 120 and the fourth sub-pixel 140 in the same column, and it is also beneficial to the uniform arrangement of the second sub-pixel 120 and the fourth sub-pixel 140 in the same column. To a certain extent, it is beneficial to make full use of the arrangement space of the display panel 10, and thus it is beneficial to improve the aperture ratio of the display panel 10.

[0147] In some embodiments, Figure 3 and Figure 4 As shown, the first sub-pixel 110 is relative to the first direction F 1 The third sub-pixel 130 is symmetrically arranged along the first symmetry line. 1 The extended second symmetry line is arranged symmetrically.

[0148] This is beneficial for uniform arrangement of the first sub-pixels 110 and the third sub-pixels 130 in the same row, which is beneficial to fully utilize the arrangement space of the display panel 10 to a certain extent, and further beneficial to improve the aperture ratio of the display panel 10.

[0149] In this embodiment, the first symmetry line of the first sub-pixel 110 and the second symmetry line of the third sub-pixel 130 in the same row are collinear and pass through the centers of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row.

[0150] In this way, the first sub-pixel 110 , the second sub-pixel 120 , the third sub-pixel 130 and the fourth sub-pixel 140 in the same row can be evenly arranged, which is beneficial to fully utilize the arrangement space of the display panel 10 to a certain extent, and further beneficial to improve the aperture ratio of the display panel 10 .

[0151] In other embodiments, Figures 5 - 8 As shown, a plurality of repeating units 100 are arranged along a first direction F 1 and the first direction F 1 The second direction of intersection F 2 Array arrangement, along the second direction F 2 In two adjacent repeating units 100, the first sub-pixel group in one repeating unit 100 and the first sub-pixel group in the other repeating unit 100 are located in the same column. 2 In two adjacent repeating units 100 , the second sub-pixel group in one repeating unit 100 and the second sub-pixel group in the other repeating unit 100 are located in the same column.

[0152] That is, the adjacent repeating units 100 in two adjacent rows are aligned along the second direction F 2 Located in the same column.

[0153] On the one hand, it is convenient to route the sub-pixels in the same column of the repeating unit 100 , and on the other hand, the repeating unit 100 can be arranged more evenly, which is beneficial to fully utilize the arrangement space of the display panel 10 to a certain extent, and further beneficial to improve the aperture ratio of the display panel 10 .

Along the first direction F 1 , in the same row, the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are arranged adjacent to each other along the first direction F 1 , which can form a pixel unit, or the first sub-pixel 110, the fourth sub-pixel 140, and the third sub-pixel 130 are arranged adjacent to each other along the first direction F 1 , which can form a pixel unit, and in the same row, there are two adjacent pixel units sharing the first sub-pixel 110 or the third sub-pixel 130. Thus, using this pixel arrangement structure can form multiple pixel units arranged in rows along the first direction F 1 , and the color mixing effect of each pixel unit is better. Furthermore, it is beneficial to improve the aperture ratio of the display panel 10 while also being beneficial to improving the display effect of the display panel 10. On the other hand, since the first sub-pixel group is arranged in columns along the second direction F 2 , and the second sub-pixel group is arranged in columns along the second direction F 2 , therefore, it is convenient for the wiring design of the first sub-pixel group in the same column and also convenient for the wiring design of the second sub-pixel group in the same column.

That is, along the first direction F 1 , the center connection lines of all the second sub-pixels 120 and all the fourth sub-pixels 140 in the same row are straight lines.

[0157] Thus, it is convenient for the wiring of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row, and it is also beneficial for the uniform arrangement of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row.

The light-emitting region of the second sub-pixel 120 includes a first pixel side 1201 adjacent to the first boundary 1101, and the first pixel side 1201 is parallel to the first boundary 1101.

[0173] It may be that the first concave portion includes a first boundary 1101 and a second boundary 1102 connected to each other (as Figure 2 and Figure 6 shown). In this way, while the first sub-pixel 110 is arranged around the adjacent second sub-pixel 120, it is also beneficial to reducing the occupied space of the first sub-pixel group, thereby making full use of the layout space of the display panel 10, and thus being beneficial to improving the aperture ratio of the display panel 10.

The light-emitting region of the second sub-pixel 120 includes two first pixel sides 1201 arranged at intervals along the second direction and a second pixel side 1202 connected between the two first pixel sides 1201.

[0175] In this way, the first sub-pixel 110 can be arranged more around the adjacent second sub-pixel 120, which is beneficial to improving the color mixing effect of the first sub-pixel 110 and the second sub-pixel 120, and thus the display effect of the display panel 10 can be improved.

[0180] It may be that the second concave portion includes a third boundary 1301 and a fourth boundary 1302 connected to each other (as Figure 2 and Figure 6 shown). In this way, while the third sub-pixel 130 is arranged around the adjacent fourth sub-pixel 140, it is also beneficial to reducing the occupied space of the second sub-pixel group, and thus the arrangement space of the display panel 10 can be made full use of, and thus is beneficial to improving the aperture ratio of the display panel 10.

[0181] It may also be that the second concave portion includes two third boundaries 1301 arranged at intervals along the second direction F 2 and a fourth boundary 1302 connected between the two third boundaries 1301.

[0186] It can be understood that the first recess and the second recess have notches with the same orientation. In this way, it is beneficial to set adjacent sub-pixels at intervals, and at the same time, it is beneficial to make full use of the arrangement space of the display panel 10, and thus it is beneficial to improve the aperture ratio of the display panel 10.

The light-emitting area of the third sub-pixel 130 includes an eleventh pixel side 1303 that is parallel to the second direction F 2 In adjacent third sub-pixels 130 and fourth sub-pixels 140, the tenth pixel side 1403 and the eleventh pixel side 1303 are collinear.

[0191] Optionally, in the third sub-pixels 130 and fourth sub-pixels 140 in the same column, the tenth pixel side 1403 and the eleventh pixel side 1303 are collinear.

[0192] Specifically, in the embodiments such as 3, Figure 4 , Figure 7 and Figure 8 shown, the fourth pixel side 1402 is connected between one ends of two third pixel sides 1401, and the tenth pixel side 1403 is connected between the other ends of the two third pixel sides 1401.

[0193] It can be understood that along the second direction F 2 , the size of the second sub-pixel group along the first direction F 1 remains unchanged, facilitating the full utilization of the layout space of the display panel 10, and thus being beneficial to improving the aperture ratio of the display panel 10.

[0194] In some embodiments, such as Figures 1 - 2 and Figures 5 - 6 shown, the light-emitting area of the second sub-pixel 120 further includes a twelfth pixel side 1204 that is opposite to and parallel to the first pixel side 1201; the light-emitting area of the first sub-pixel 110 includes a thirteenth pixel side 1104. In adjacent first sub-pixels 110 and second sub-pixels 120, the twelfth pixel side 1204 and the thirteenth pixel side 1104 are collinear.

[0195] Optionally, in the first sub-pixels 110 and second sub-pixels 120 in the same row, the twelfth pixel side 1204 and the thirteenth pixel side 1104 are collinear.

[0196] It can be understood that along the first direction F 1 , the size of the first sub-pixel group along the second direction F 2 remains unchanged, facilitating the full utilization of the layout space of the display panel 10, and thus being beneficial to improving the aperture ratio of the display panel 10.

[0197] In some embodiments, such as Figures 1 - 2 andFigures 5 - 6 As shown, the light-emitting area of the fourth sub-pixel 140 further includes a fourteenth pixel edge 1404 that is opposite to and parallel to the third pixel edge 1401. The light-emitting area of the third sub-pixel 130 includes a fifteenth pixel edge 1304. Among adjacent third sub-pixels 130 and fourth sub-pixels 140, the fourteenth pixel edge 1404 and the fifteenth pixel edge 1304 are collinear.

[0198] Optionally, among the third sub-pixels 130 and fourth sub-pixels 140 in the same row, the fourteenth pixel edge 1404 and the fifteenth pixel edge 1304 are collinear.

[0199] It can be understood that along the first direction F 1 , the size of the second sub-pixel group remains unchanged along the second direction F 2 , which is convenient for making full use of the layout space of the display panel 10, and thus is beneficial to improving the aperture ratio of the display panel 10.

[0200] In this embodiment, among the first sub-pixel and the second sub-pixel group in the same row, the twelfth pixel edge 1204, the thirteenth pixel edge 1104, the fourteenth pixel edge 1404 and the fifteenth pixel edge 1304 are collinear.

[0201] In this way, the two sides of the first sub-pixel and the second sub-pixel group in the same row are flush along the second direction F 2 , which is convenient for making full use of the layout space of the display panel 10, and thus is beneficial to improving the aperture ratio of the display panel 10.

[0202] In some embodiments, the light-emitting area of the first sub-pixel 110 is greater than or equal to the light-emitting area of the third sub-pixel 130.

[0203] The relative relationship between the light-emitting area of the first sub-pixel 110 and the light-emitting area of the third sub-pixel 130 can be selected according to factors such as the light-emitting colors of the first sub-pixel 110 and the third sub-pixel 130, device requirements and manufacturing processes. It can be selected that the light-emitting area of the first sub-pixel 110 is greater than the light-emitting area of the third sub-pixel 130, or it can be selected that the light-emitting area of the first sub-pixel 110 is equal to the light-emitting area of the third sub-pixel 130, and no special limitation is made here.

[0204] In some other embodiments, the light-emitting area of the second sub-pixel 120 is equal to the light-emitting area of the fourth sub-pixel 140, because the light-emitting colors of the second sub-pixel 120 and the fourth sub-pixel 140 are the same. Exemplarily, the second sub-pixel 120 and the fourth sub-pixel 140 can be set as sub-pixels of colors sensitive to the human eye, such as green sub-pixels, which is beneficial to improving the resolution of the display panel 10 while making the display of the display panel 10 more uniform.

[0205] In some other embodiments, the light-emitting area of the first sub-pixel 110 is greater than or equal to the light-emitting area of the third sub-pixel 130, and the light-emitting area of the second sub-pixel 120 is equal to the light-emitting area of the fourth sub-pixel 140.

[0206] Optionally, referring to Figure 2 , Figure 4 , Figure 6 and Figure 8 , the light-emitting area of the first sub-pixel 110 is greater than the light-emitting area of the third sub-pixel 130. The light-emitting area of the first sub-pixel 110 has a first sub-light-emitting area 110a extending along the first direction F 1 , and a second sub-light-emitting area 110b extending along the second direction F 2 . The light-emitting area of the third sub-pixel 130 has a third sub-light-emitting area 130a extending along the first direction F 1 , and a fourth sub-light-emitting area 130b extending along the second direction F 2 . Among them, the size of the first sub-light-emitting area 110a along the second direction F 2 is equal to the size of the third sub-light-emitting area 130a along the second direction F 2 . The size of the second sub-light-emitting area 110b along the first direction is greater than the size of the fourth sub-light-emitting area 130b along the first direction.

[0207] When the lifespan of the first sub-pixel 110 is relatively low, the lifespans of the second sub-pixel 120 and the fourth sub-pixel 140 are at the medium level, and the lifespan of the third sub-pixel 130 is relatively high, the size of the second sub-light-emitting area 110b along the first direction is set to be greater than the size of the fourth sub-light-emitting area 130b along the first direction, and the size of the first sub-light-emitting area 110a along the second direction F 2 is equal to the size of the third sub-light-emitting area 130a along the second direction F 2 . In this way, the light-emitting area of the first sub-pixel 110 can be increased to a certain extent, and the light-emitting area of the third sub-pixel 130 can be reduced to a certain extent, which can well balance the overall lifespan of the first sub-pixel 110 and the third sub-pixel 130, that is, the lifespan of the display panel 10 can be improved.

[0208] In addition, since the size of the first sub-light-emitting area 110a along the second direction F 2 is equal to the size of the third sub-light-emitting area 130a along the second direction F 2 , the sizes of the first sub-pixel 110 and the third sub-pixel 130 in the same row are equal. In this way, it is convenient to make full use of the layout space of the display panel 10, and thus it is beneficial to improve the aperture ratio of the display panel 10.

[0209] In some embodiments, among four adjacent sub-pixel groups in two adjacent rows, a quadrilateral is formed by connecting the centers of two second sub-pixels 120 and the centers of two fourth sub-pixels 140. The quadrilateral includes a first side L1 and a second side L2 that are oppositely arranged along the second direction F 2 and a third side L3 and a fourth side L4 that are oppositely arranged along 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 .

[0210] That is to say, it can be that the first side L1 is parallel to the first direction F 1 , or it can be that the second side L2 is parallel to the first direction F 1 , or it can be that both the first side L1 and the second side L2 are parallel to the first direction F 1 .

[0211] Exemplarily, as Figures 1 - 8 shown, both the first side L1 and the second side L2 are parallel to the first direction F 1 .

[0212] It can be understood that the line connecting the centers of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row is a straight line. In this way, it is convenient for the wiring of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row, and it is also beneficial to the uniform arrangement of the second sub-pixel 120 and the fourth sub-pixel 140 in the same row. To a certain extent, it is beneficial to make full use of the arrangement space of the display panel 10, and thus beneficial to improving the aperture ratio of the display panel 10.

[0213] In some embodiments, it can be that the length of the first side L1 is not equal to the length of the second side L2.

[0214] It can also be that the lengths of the third side L3 and the fourth side L4 are equal. It can also be that the length of the first side L1 is not equal to the length of the second side L2, and the lengths of the third side L3 and the fourth side L4 are equal (as Figures 1 - 4 shown).

[0215] Optionally, the quadrilateral is a trapezoid. Specifically, the quadrilateral is an isosceles trapezoid.

[0216] In this way, among four adjacent sub-pixel groups in two adjacent rows, the two second sub-pixels 120 and the two fourth sub-pixels 140 are arranged more uniformly. To a certain extent, it is beneficial to make full use of the arrangement space of the display panel 10, and thus beneficial to improving the aperture ratio of the display panel 10.

[0217] In some other embodiments, it may be that the length of the first side L1 is equal to the length of the second side L2. It may also be that the length of the third side L3 is equal to the length of the fourth side L4. Of course, it may also be that the length of the first side L1 is equal to the length of the second side L2, and the length of the third side L3 is equal to the length of the fourth side L4 (as Figures 5 - 9 shown).

[0218] In this way, among the adjacent four sub-pixel groups in adjacent two rows, the two second sub-pixels 120 and the two fourth sub-pixels 140 are arranged more evenly, which can make the multiple second sub-pixels 120 and the multiple fourth sub-pixels 140 arranged more evenly. To a certain extent, it is beneficial to make full use of the arrangement space of the display panel 10, and then beneficial to improve the aperture ratio of the display panel 10.

[0219] Optionally, the quadrilateral is a rectangle. Specifically, in the embodiment as Figure 9 shown, the quadrilateral is a square.

[0220] In this way, the multiple second sub-pixels 120 and the multiple fourth sub-pixels 140 are arranged more evenly. To a certain extent, it is beneficial to make full use of the arrangement space of the display panel 10, and then beneficial to improve the aperture ratio of the display panel 10. If both the second sub-pixel 120 and the fourth sub-pixel 140 are green sub-pixels, the evenly arranged multiple green sub-pixels are also beneficial to improve the display effect of the display panel 10.

[0221] In some embodiments, both the second sub-pixel 120 and the fourth sub-pixel 140 are green sub-pixels, and the light-emitting colors of the first sub-pixel 110 and the third sub-pixel 130 are different. In this way, it can make better use of three sub-pixels of different colors to form a pixel unit, which is more beneficial to improve the display effect of the display panel 10.

[0222] 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 a blue sub-pixel and a red sub-pixel.

[0223] Specifically, the first sub-pixel 110 is a blue sub-pixel, and the third sub-pixel 130 is a red sub-pixel.

[0224] The red sub-pixel, the green sub-pixel, and the blue sub-pixel constitute the three primary colors for color display of the display panel 10, and the color display of the display panel 10 can be realized.

[0225] Optionally, the light-emitting area of the blue sub-pixel is larger than the light-emitting area of the red sub-pixel and larger than the light-emitting area of the green sub-pixel.

[0226] 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.

[0227] According to a second aspect of the present application, a display panel 10 is provided, including the pixel arrangement structure of any of the above embodiments.

[0228] Optionally, referring to Figure 10 , the display panel 10 further includes a substrate 210 and a isolation structure 300. The plurality of repeating units 100 and the isolation structure 300 are both disposed on the substrate 210 ( Figure 10 In, the fourth sub-pixel 140 is not shown), and the isolation structure 300 is used to space apart adjacent repeating units 100, and is used to space apart 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 in the same repeating unit 100.

[0229] The isolation structure 300 is used to space apart the pixel materials of 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. In this way, in the process of forming the plurality of repeating units 100 by evaporation coating, an expensive fine metal mask (FMM) can be discarded. In this way, 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 no longer limited by the fine metal mask (FMM), and the isolation 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 beneficial to improving the aperture ratio of the display panel 10 while reducing the manufacturing cost of the display panel 10.

[0230] In some embodiments, the outer contour of the top surface of the isolation structure 300 in the orthographic projection on the substrate 210 is located outside the outer contour of the bottom surface of the isolation structure 300 in the orthographic projection on the substrate 210.

[0231] Specifically, the isolation structure 300 includes a first isolation portion 310 and a second isolation portion 320 stacked on the substrate 210. The outer contour of the second isolation portion 320 in the orthographic projection on the substrate 210 is located outside the outer contour of the corresponding first isolation portion 310 in the orthographic projection on the substrate 210.

[0232] Optionally, the width of the bottom surface of the second isolation portion 320 is greater than the width of the top surface of the first isolation portion 310. The width refers to the distance between one side of the isolation structure 300 close to one color sub-pixel and the other side of the isolation structure 300 close to another color sub-pixel.

[0233] In this way, the isolation structure 300 is used to isolate the pixel materials of adjacent sub-pixels in the repeating unit 100 during evaporation. When preparing the display panel 10, the isolation structure 300 can have a better isolation effect on the pixel materials corresponding to the sub-pixels of the repeating unit 100 and the packaging materials corresponding to the packaging unit 400, which is conducive to forming an isolation structure 300 that can serve as a complete packaging structure for the sub-pixels of the repeating unit 100.

[0234] In some embodiments, the display panel 10 further includes a pixel defining layer 220 disposed on the substrate 210 .

[0235] The material of the pixel defining layer 220 may be polyimide, acrylic or polyethylene terephthalate, etc., and the shape of the orthographic projection of the pixel opening 2201 on the substrate 210 may be a rectangle or a trapezoid, etc.

[0236] 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 area 102 and a second electrode 103 which are stacked together. A plurality of pixel openings 2201 which at least partially expose the first electrode 101 are provided on the pixel defining layer 220. The light-emitting area 102 and the second electrode 103 are arranged at corresponding pixel openings 2201. The isolation 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 are correspondingly connected to the plurality of first openings 301.

[0237] Specifically, the first electrode 101 is an anode, and the second electrode 103 is a cathode.

[0238] Specifically, the plurality of pixel openings 2201 may be connected to the plurality of first openings 301 in a one-to-one correspondence.

[0239] The substrate 210 may be an array substrate, which includes a stacked substrate, a drive array layer, and a flat layer, wherein the substrate may be flexible polyimide (PI), rigid glass, or a thin metal sheet, etc. The present application embodiment will not discuss substrates of other materials in detail, and those skilled in the art may select different types of materials according to actual needs.

[0240] It should be noted that the isolation structure 300 may be directly disposed on the substrate 210 , or may be indirectly disposed on the substrate 210 . For example, the pixel defining layer 220 is disposed on the substrate 210 , and the isolation structure 300 is disposed on the pixel defining layer 220 .

[0241] In some embodiments, the display panel 10 further includes a plurality of encapsulation units 400. The plurality of encapsulation units 400 are respectively disposed in the plurality of first openings 301, and the encapsulation unit 400 completely covers 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.

[0242] The material of the encapsulation unit 400 may include at least one of an organic material and an inorganic material.

[0243] On the one hand, the encapsulation unit 400 can be used to block moisture from entering the first sub-pixel 110, the corresponding second sub-pixel 120, the corresponding third sub-pixel 130, or the corresponding fourth sub-pixel 140, forming an independent encapsulation of 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 beneficial to improving the reliability of the display panel 10; on the other hand, the second electrode 103 can be in contact with the adjacent isolation structure 300 and electrically connected. It is convenient to supply a specified potential to the second electrode 103 of the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 through the isolation structure 300.

[0244] In some embodiments, the display panel 10 further includes an encapsulation layer 500. The encapsulation layer 500 is disposed on the isolation structure 300 and covers the plurality of encapsulation units 400.

[0245] The material of the encapsulation layer 500 may include at least one of an organic material and an inorganic material.

[0246] The encapsulation layer 500 is equivalent to an overall encapsulation structure. The encapsulation layer 500 is used to encapsulate all the first sub-pixels 110, all the second sub-pixels 120, all the third sub-pixels 130, all the fourth sub-pixels 140, and all the encapsulation units 400.

[0247] The encapsulation layer 500 combined with the encapsulation unit 400 is equivalent to a double encapsulation effect on the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140, improving the moisture barrier ability, and thus improving the reliability of the display panel 10.

[0248] As Figure 11 and Figure 12 shown, according to the third aspect of the present application, a pixel arrangement structure is provided. The pixel arrangement structure includes a plurality of sub-pixels. The plurality of sub-pixels include a first sub-pixel 110, a second sub-pixel 120, and a third sub-pixel 130 that emit different color lights. The first sub-pixel 110 and the third sub-pixel 130 are in the first direction F 1alternately arranged above, and the adjacent first sub-pixel 110 and third sub-pixel 130 are separated by a second sub-pixel 120 in the first direction F 1 In the first direction F, both the first sub-pixel 110 and the third sub-pixel 130 adjacent to the second sub-pixel 120 have partial structures arranged around the second sub-pixel 120.

[0249] In this way, the color mixing effect of the adjacent first sub-pixel 110 and second sub-pixel 120 can be better, and the color mixing effect of the adjacent second sub-pixel 120 and third sub-pixel 130 can be better. Furthermore, it is beneficial to improve the display effect of the display panel 10. Combining that the adjacent first sub-pixel 110 and third sub-pixel 130 are separated by a 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 better, and the arrangement of the first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130 in the pixel unit is relatively compact. In this way, by using this pixel arrangement structure, while improving the aperture ratio of the display panel 10 including this pixel arrangement structure, the display effect of the display panel 10 can also be improved.

[0250] In some embodiments, the light-emitting region of the first sub-pixel 110 has a third concave portion with an opening facing the adjacent second sub-pixel 120, and the light-emitting region of the third sub-pixel 130 has a fourth concave portion with an opening facing the adjacent second sub-pixel 120. Among them, in the adjacent first sub-pixel 110 and third sub-pixel 130, the third concave portion and the adjacent fourth concave portion define a third accommodation space C, and the third accommodation space C is used to accommodate the second sub-pixel 120 between the adjacent first sub-pixel 110 and third sub-pixel 130.

[0251] In this way, part of the structure of the first sub-pixel 110 can be arranged around the adjacent second sub-pixel 120, and part of the structure of the third sub-pixel 130 can be arranged around the adjacent second sub-pixel 120. On the one hand, it can improve the color mixing effect of the sequentially adjacent first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130. On the other hand, the arrangement of the sequentially adjacent first sub-pixel 110, second sub-pixel 120, and third sub-pixel 130 is more compact, which is also beneficial to making full use of the arrangement space of the display panel 10, and thus beneficial to improving the aperture ratio of the display panel 10.

[0252] In some embodiments, the third concave portion has a fifth boundary 1105 parallel to the first direction F 1 and the fourth concave portion has a sixth boundary 1305 parallel to the first direction F 1For the sixth boundary 1305, 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 is collinear with the fifth boundary 1105 and both are parallel to the fifth pixel side 1205.

[0253] In this way, the sixth boundary 1305 can be flush with the fifth boundary 1105, and the distances between the sixth boundary 1305 and the adjacent fifth pixel side 1205, and between the fifth boundary 1105 and the adjacent fifth pixel side 1205 are equal and equally spaced, which is beneficial to 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 also convenient for making full use of the layout space of the display panel 10, thereby being beneficial to improving the aperture ratio of the display panel 10.

[0254] In this embodiment, the third recess further has a seventh boundary 1106 intersecting with the first direction F 1 and parallel to the second 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 opposite to the sixth pixel side 1206, and the seventh pixel side 1207 is parallel to the eighth boundary 1306.

[0255] Optionally, the first direction F 1 is perpendicular to the second direction F 2 to each other.

[0256] In this way, the distance between the sixth pixel side 1206 and the seventh boundary 1106 can be equally spaced, which is beneficial to reducing the difficulty of the manufacturing processes of the first sub-pixel 110 and the second sub-pixel 120. Also, the distance between the seventh pixel side 1207 and the eighth boundary 1306 can be equally spaced, which is beneficial to reducing the difficulty of the manufacturing processes of the second sub-pixel 120 and the third sub-pixel 130, and also convenient for making full use of the layout space of the display panel 10, thereby being beneficial to improving the aperture ratio of the display panel 10.

[0257] In this embodiment, the third recess includes two fifth boundaries 1105 spaced along 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 spaced along the second direction F 2 and a sixth pixel side 1206 and a seventh pixel side 1207 connecting the two fifth pixel sides 1205.

[0258] In this way, the first sub-pixel 110 can surround the adjacent second sub-pixel 120 more, improving the color mixing effect of the first sub-pixel 110 and the second sub-pixel 120, and also being beneficial to improving the display effect of the display panel 10.

[0259] In this embodiment, the fourth concave portion includes two sixth boundaries 1305 arranged at intervals along the second direction F 2 and an eighth boundary 1306 connecting between the two sixth boundaries 1305.

[0260] In this way, the third sub-pixel 130 can surround the adjacent second sub-pixel 120 more, improving the color mixing effect of the second sub-pixel 120 and the third sub-pixel 130, and also being beneficial to improving the display effect of the display panel 10.

[0261] In some embodiments, referring to Figure 11 the first sub-pixel 110 and the third sub-pixel 130 are arranged in a column along a second direction F 1 intersecting with the first direction F 2 in a row.

[0262] In this way, the problems of color fringes, stripe sense and jagged sense caused by the sub-pixels of the same column having the same light-emitting color can be improved, which is beneficial to reducing the color fringe problem, stripe sense and jagged sense of the display picture, and thus the display effect of the display panel 10 can be improved.

[0263] In other embodiments, referring to Figure 12 the first sub-pixel 110 is arranged in a column along a second direction F 1 intersecting with the first direction F 2 in a row, and the third sub-pixel 130 is arranged in a column along the second direction F 2 in a row.

[0264] On the one hand, it is convenient to route the wires for all the first sub-pixels 110 in the same column, and it is also convenient to route the wires for all the third sub-pixels 130 in the same column. On the other hand, multiple sub-pixels can be arranged more evenly, which is beneficial to making full use of the layout space of the display panel 10 to a certain extent, and thus is beneficial to improving the aperture ratio of the display panel 10.
