Detailed Implementation

[0079] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0080] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0081] Furthermore, where 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 number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0082] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0083] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0084] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening 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 intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0085] The display panel in the related technology includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. In order to balance the uniformity and density of the sub-pixel arrangement, a balance is sought among the three, so that the four third sub-pixels are arranged around the first sub-pixel, and the spacing between the four third sub-pixels and the first sub-pixel is not equal, which leads to the color shift problem in the display panel in the related technology.

[0086] To address the aforementioned technical problems, this application designs a pixel arrangement structure and a display device, aiming to improve the color shift problem of the display panel and display device including the pixel arrangement structure, while also taking into account the uniformity and density of the sub-pixel arrangement.

[0087] Figure 1 A schematic diagram of the pixel arrangement structure 100 in one embodiment of this application is shown. Figure 2 A schematic diagram of the structure of the first virtual quadrilateral corresponding to the repeating unit group is shown.

[0088] Please refer to the following: Figure 1 and Figure 2 One embodiment of this application provides a pixel arrangement structure 100, including multiple repeating units. Each repeating unit includes two first sub-pixels 110, two second sub-pixels 120, and a third sub-pixel 130 arranged in alignment. In the repeating unit, the two first sub-pixels 110 and the two second sub-pixels 120 are arranged at intervals around the third sub-pixel 130.

[0089] A first virtual quadrilateral S1 is formed by connecting the centers of the two first sub-pixels 110 and the two second sub-pixels 120 that are aligned. The third sub-pixel 130 is located inside the first virtual quadrilateral S1.

[0090] Two adjacent repeating units share a first sub-pixel 110 and a second sub-pixel 120. Four adjacent repeating units share a target sub-pixel, which is one of the first sub-pixel 110 and the second sub-pixel 120. A repeating unit group is defined to include these four adjacent repeating units. In the repeating unit group, the third sub-pixels 130 of the four repeating units are symmetrically arranged with reference to the target sub-pixel.

[0091] On the one hand, in the repeating unit, two first sub-pixels 110 and two second sub-pixels 120 are arranged around the third sub-pixel 130 at intervals. Two adjacent repeating units share one first sub-pixel 110 and one second sub-pixel 120, and four adjacent repeating units share one target sub-pixel. In this way, the arrangement of multiple sub-pixels in the repeating unit can be compact, and the arrangement of multiple adjacent repeating units is also relatively compact, which is beneficial to reduce the risk of color mixing while improving resolution.

[0092] On the other hand, in the repeating unit group, the third sub-pixel 130 of the four repeating units is arranged symmetrically with reference to the target sub-pixel.

[0093] It could be that, in a repeating unit group, the third sub-pixel 130 of the four repeating units is arranged symmetrically with reference to the first sub-pixel 110.

[0094] Alternatively, in a repeating unit group, the third sub-pixel 130 of the four repeating units is arranged symmetrically with reference to the second sub-pixel 120.

[0095] In this way, when the light generated by the third sub-pixel 130 of the four repeating units is evenly dispersed, the balance or symmetry of the color viewing angle can be better generated. It can also reduce the probability of color shift in the touch layer 500 at the position corresponding to the third sub-pixel 130 of the four repeating units due to asymmetrical design, thereby improving the color shift problem of the display panel 10 including the pixel arrangement structure 100.

[0096] Therefore, the pixel arrangement structure 100 can improve resolution while reducing the risk of color mixing, and can also improve the color deviation problem of the display panel 10 including the pixel arrangement structure 100.

[0097] In some embodiments, such as Figure 3 As shown, the target sub-pixels are symmetrically arranged with reference plane M as the reference object. In the repeating unit group, the third sub-pixels 130 of the four repeating units are symmetrically arranged with reference plane M as the reference object. Reference plane M is perpendicular to the first direction F1 and coincides with the center of the target sub-pixels.

[0098] The first direction F1 is perpendicular to the thickness direction of the pixel arrangement structure 100, that is, perpendicular to the thickness direction of the display panel 10.

[0099] Alternatively, in a repeating unit group, the third sub-pixels 130 of the four repeating units are arranged symmetrically with reference to the first sub-pixel 110. The reference plane M is perpendicular to the first direction F1 and coincides with the center of the first sub-pixel 110.

[0100] Alternatively, in the repeating unit group, the third sub-pixels 130 of the four repeating units are arranged symmetrically with reference to the second sub-pixel 120. The reference plane M is perpendicular to the first direction F1 and coincides with the center of the second sub-pixel 120.

[0101] Since the third sub-pixels 130 of the four repeating units are symmetrically arranged with reference plane M as the reference object, the light generated by the third sub-pixels 130 of the four repeating units can be evenly dispersed on both sides of the first direction F1, which can better produce the balance or symmetry of the color viewing angle, thereby effectively reducing the risk of color deviation of the display panel 10 and improving the display effect of the display panel 10.

[0102] In some embodiments, a plurality of repeating units are arranged in a row along a first direction F1 and in a column along a second direction F2. The first direction F1 and the second direction F2 intersect each other and are both perpendicular to the thickness direction of the pixel arrangement structure 100.

[0103] Optionally, the first direction F1 and the second direction F2 are perpendicular to the thickness direction of the pixel arrangement structure 100. For example, one of the first direction F1 and the second direction F2 is parallel to the length direction of the display panel 10, and the other of the first direction F1 and the second direction F2 is parallel to the width direction of the display panel 10.

[0104] In this way, multiple repeating units can be arranged in rows and columns, and correspondingly, multiple sub-pixels can also be arranged in rows and columns, which is beneficial to deploy more sub-pixels in a unit area, thereby improving the resolution of the display panel 10 including the pixel arrangement structure 100.

[0105] In some embodiments, in the repeating unit group, the third sub-pixels 130 of the four repeating units are arranged around the target sub-pixel at intervals, and the spacing between the third sub-pixels 130 of the four repeating units and the target sub-pixel is equal.

[0106] It can be that, in the repeating unit group, the third sub-pixels 130 of the four repeating units are arranged around the first sub-pixel 110 at intervals, and the spacing between the third sub-pixels 130 and the first sub-pixel 110 of the four repeating units is equal.

[0107] In other words, in the repeating unit group, the spacing between the third sub-pixel 130 and the first sub-pixel 110 of the four repeating units are the first spacing L1, the second spacing L2, the third spacing L3, and the fourth spacing L4, respectively (e.g., ...). Figure 4 As shown), L1 = L2 = L3 = L4.

[0108] Alternatively, in the repeating unit group, the third sub-pixels 130 of the four repeating units are arranged around the second sub-pixels 120 at intervals, and the spacing between the third sub-pixels 130 and the second sub-pixels 120 of the four repeating units is equal.

[0109] In other words, in the repeating unit group, the spacing between the third sub-pixel 130 and the second sub-pixel 120 of the four repeating units are the fifth spacing L5, the sixth spacing L6, the seventh spacing L7, and the eighth spacing L8, respectively (e.g., ...). Figure 4 As shown), L5 = L6 = L7 = L8.

[0110] In this way, the third sub-pixels 130 of the four repeating units in the repeating unit group can be arranged more evenly around the target sub-pixel. In fact, the third sub-pixels 130 of the four repeating units in the repeating unit group can be arranged around the target sub-pixel at equal intervals. This can improve the color mixing effect between the third sub-pixels 130 of the four repeating units and the target sub-pixel, and also better produce the balance or symmetry of the color viewing angle. This can effectively reduce the color deviation risk of the display panel 10 and thus improve the display effect of the display panel 10.

[0111] In some embodiments, in the repeating unit group, the spacing between any two third sub-pixels 130 of the four repeating units is greater than or equal to 15 micrometers.

[0112] Optionally, the spacing between any two third sub-pixels 130 in the four repeating units is 15 micrometers to 30 micrometers. For example, the spacing between any two third sub-pixels 130 in the four repeating units is 15 micrometers, 20 micrometers, 25 micrometers or 30 micrometers.

[0113] Compared to the unequal spacing between the third sub-pixels 130 and the target sub-pixels of the four repeating units, in this application, the spacing between the third sub-pixels 130 and the target sub-pixels of the four repeating units is equal. This makes the layout of the third sub-pixels 130 of the four repeating units more compact and can also effectively reduce the risk of color shift in the display panel 10. In this case, it is also necessary to ensure that the spacing between two adjacent third sub-pixels 130 meets the application requirements of the fine metal mask (FMM) so that the pixel arrangement structure 100 can be made using the fine metal mask (FMM).

[0114] In some embodiments, the first virtual quadrilateral S1 includes two first hypotenuses S11 facing each other, and a first short side S12 and a first long side S13 facing each other. The first short side S12 is connected between one end of the two first hypotenuses S11, and the first long side S13 is connected between the other end of the two first hypotenuses S11.

[0115] Compared to a rectangle whose opposite sides have the same length as the first long side S13, in this application, the length of the first short side S12 of the first virtual quadrilateral S1 is shorter than the length of the first long side S13. This allows for a more compact arrangement of the first sub-pixel 110 and the second sub-pixel 120 adjacent to each other along the extension direction of the first short side S12. It also allows the first sub-pixel 110 and the second sub-pixel 120 adjacent to each other along the extension direction of the first short side S12 to be staggered in the direction in which the first short side S12 and the first long side S13 are set opposite each other. This improves the color mixing effect between the first sub-pixel 110 and the adjacent second sub-pixel 120, while also mitigating the problem of color fringing.

[0116] In some embodiments, the first short side S12 of the first virtual quadrilateral S1 is arranged parallel to the first long side S13 of the first virtual quadrilateral S1.

[0117] Optionally, the first short side S12 and the first long side S13 of the first virtual quadrilateral S1 are both parallel to the second direction F2.

[0118] It can be understood that, in the second direction F2, the line connecting the centers of the first sub-pixel 110 and the second sub-pixel 120 is parallel to the second direction F2.

[0119] This facilitates the regular arrangement of the first sub-pixel 110 and the second sub-pixel 120, thereby improving the regularity of the pixel arrangement structure 100. It can also better improve the color shift problem of the display panel 10, which includes the pixel arrangement structure 100, and also help improve the resolution of the display panel 10.

[0120] In some embodiments, the two first hypotenuses S11 of the first virtual quadrilateral S1 have equal lengths.

[0121] Optionally, the extension direction of the first hypotenuse S11 of the first virtual quadrilateral S1, the first direction and the second direction intersect each other.

[0122] It can be understood that the extension direction of the first hypotenuse S11 of the first virtual quadrilateral S1 is perpendicular to the thickness direction of the pixel arrangement structure 100.

[0123] Optionally, the first virtual quadrilateral S1 is an isosceles trapezoid.

[0124] The two first hypotenuses S11 of the first virtual quadrilateral S1 have equal lengths, which can improve the regularity of the arrangement of multiple sub-pixels in the repeating unit, thereby facilitating the regular arrangement of multiple repeating units. This can improve the color shift problem of the display panel 10 including the pixel arrangement structure 100, and also help to improve the resolution of the display panel 10.

[0125] In some embodiments, two adjacent repeating units along the first direction F1 are symmetrically distributed with reference to a shared first sub-pixel 110 and / or second sub-pixel 120.

[0126] In the second direction F2, the center line connecting the first sub-pixel 110 and the second sub-pixel 120 is parallel to the second direction F2. This makes it easier for two adjacent repeating units along the first direction F1 to be symmetrically distributed with the shared first sub-pixel 110 and the second sub-pixel 120 as reference objects. This allows the sub-pixels of two adjacent repeating units along the first direction F1 to have a balance or symmetry in color viewing angle, thereby effectively reducing the risk of color shift in the display panel 10 and improving the display effect of the display panel 10.

[0127] In some embodiments, two adjacent repeating units along the second direction F2, wherein one repeating unit is rotated 180 degrees to become mirror symmetrical with the other repeating unit.

[0128] This not only arranges subpixels that avoid emitting the same color of light in the row or column direction into a separate column, but also weakens the protrusion of subpixels located in the same row or column, further improving the color fringing problem at the display edge. In addition, rotating one repeating unit 180 degrees to form a mirror image with another repeating unit can also maximize the light-transmitting reserved area Q between adjacent repeating units, which is beneficial to increasing the light-receiving area of ​​the under-display photosensitive device.

[0129] In some embodiments, such as Figure 4 As shown, in the repeating unit group, a second virtual quadrilateral S2 is formed by connecting the centers of the third sub-pixels 130 of the four repeating units as vertices, and the target sub-pixel is located within the second virtual quadrilateral S2.

[0130] The second virtual quadrilateral S2 includes two opposing second hypotenuses S21, and opposing second short sides S22 and second long sides S23. The second short side S22 is connected between one end of the two second hypotenuses S21, and the second long side S23 is connected between the other end of the two second hypotenuses S21.

[0131] It is understood that the length of the second short side S22 is less than the length of the second long side S23. Thus, in the extension direction of the second oblique side S21, two adjacent third sub-pixels 130 are staggered along the extension direction of the second short side S22. This reduces the occurrence of multiple third sub-pixels 130 of the same color being arranged in a row, thereby improving the color edge problem of the display panel 10. In addition, in the repeating unit group, the spacing between the two third sub-pixels 130 located at both ends of the second short side S22 is smaller, and the arrangement of the two third sub-pixels 130 is more compact, which can further improve the resolution of the display panel 10.

[0132] In some embodiments, the second short side S22 of the second virtual quadrilateral S2 is arranged parallel to the second long side S23 of the second virtual quadrilateral S2.

[0133] Optionally, the second short side S22 and the second long side S23 of the second virtual quadrilateral S2 are both parallel to the first direction F1.

[0134] It is understandable that, in the first direction F1, the center line connecting the multiple third sub-pixels 130 is parallel to the first direction F1.

[0135] This allows multiple third sub-pixels 130 to be arranged in a regular manner, thereby improving the regularity of the pixel arrangement structure 100. It can also better improve the color shift problem of the display panel 10, which includes the pixel arrangement structure 100, and also help to improve the resolution of the display panel 10.

[0136] In some embodiments, the lengths of the two second hypotenuses S21 of the second virtual quadrilateral S2 are equal.

[0137] Specifically, the extension direction of the second hypotenuse S21 of the second virtual quadrilateral S2, the first direction F1, and the second direction F2 intersect each other. It can be understood that the extension direction of the second hypotenuse S21, the first direction F1, and the second direction F2 are all perpendicular to the thickness direction of the pixel arrangement structure 100.

[0138] Optionally, the second virtual quadrilateral S2 has a first virtual axis of symmetry parallel to the second direction F2, and the third sub-pixels 130 of the four repeating units of the repeating unit group are symmetrically arranged with reference to the first virtual axis of symmetry of the second virtual quadrilateral S2. The first virtual axis of symmetry coincides with the aforementioned reference plane.

[0139] Optionally, the second virtual quadrilateral S2 is an isosceles trapezoid.

[0140] The two first hypotenuses S11 of the first virtual quadrilateral S1 have equal lengths, which can improve the regularity of the arrangement of the third sub-pixels 130 of the four repeating units of the repeating unit group. This can improve the color shift problem of the display panel 10 including the pixel arrangement structure 100, and also help to improve the resolution of the display panel 10.

[0141] Optionally, within the first virtual quadrilateral S1, the line connecting the centers of two oppositely positioned first sub-pixels 110 is the first diagonal, and the line connecting the centers of two oppositely positioned second sub-pixels 120 is the second diagonal. Within the first virtual quadrilateral S1, the center of the third sub-pixel 130 is set away from the intersection of the first and second diagonals.

[0142] Optionally, within the second virtual quadrilateral S2, the line connecting the centers of two oppositely positioned third sub-pixels 130 is the third diagonal, and the line connecting the centers of two oppositely positioned third sub-pixels 130 is the fourth diagonal. Within the second virtual quadrilateral S2, the center of the target sub-pixel is set away from the intersection of the third and fourth diagonals.

[0143] It is understandable that the first sub-pixel 110 and the third sub-pixel 130 are not set in the same row or column, and the second sub-pixel 120 and the third sub-pixel 130 are also not set in the same row or column. In this way, not only are sub-pixels that avoid emitting the same color light in the row or column direction arranged in a separate column, but the protrusion of sub-pixels located in the same row or column is also weakened, further improving the color edge problem of the display.

[0144] In some embodiments, the third sub-pixels 130 of the four repeating units in the repeating unit group are arranged to form a first pixel group and a second pixel group that are spaced apart along the second direction F2. The first pixel group and the second pixel group each include two third sub-pixels 130 that are spaced apart along the first direction F1. The first direction F1 and the second direction F2 intersect each other and are both perpendicular to the thickness direction of the pixel arrangement structure 100.

[0145] The spacing between two third sub-pixels 130 in the first pixel group along the first direction F1 is not equal to the spacing between two third sub-pixels 130 in the second pixel group along the first direction F1.

[0146] It is possible that the distance between two third sub-pixels 130 in the first pixel group along the first direction F1 is greater than the distance between two third sub-pixels 130 in the second pixel group along the first direction F1. Alternatively, it is possible that the distance between two third sub-pixels 130 in the first pixel group along the first direction F1 is less than the distance between two third sub-pixels 130 in the second pixel group along the first direction F1.

[0147] Optionally, the first direction F1 and the second direction F2 are perpendicular to each other and both are perpendicular to the thickness direction of the pixel arrangement structure 100.

[0148] Since the spacing between the two third sub-pixels 130 in the first pixel group along the first direction F1 is not equal to the spacing between the two third sub-pixels 130 in the second pixel group along the first direction F1, the target pixel group is defined as the one with the smaller spacing between the two third sub-pixels 130 in the first pixel group and the second pixel group along the first direction F1. Therefore, the spacing between the two third sub-pixels 130 in the target pixel group along the first direction F1 is smaller, which makes the arrangement of the two third sub-pixels 130 in the target pixel group more compact, which is beneficial to improving the resolution of the display panel 10.

[0149] In some embodiments, the spacing between two third sub-pixels 130 in the first pixel group along the first direction F1 and the spacing between two third sub-pixels 130 in the second pixel group along the first direction F1 are both greater than or equal to 15 micrometers.

[0150] In this way, the arrangement of the two third sub-pixels 130 of the target pixel group can be more compact, and the spacing between two adjacent third sub-pixels 130 can meet the application requirements of fine metal mask (FMM) so as to use fine metal mask (FMM) to make pixel arrangement structure 100.

[0151] In some embodiments, such as Figure 5As shown, the third sub-pixel 130 includes two extended edges 131 disposed opposite each other along the first direction F1. The distance between two adjacent extended edges 131 in the two third sub-pixels 130 of the first pixel group along the first direction F1 and the distance between two adjacent extended edges 131 in the two third sub-pixels 130 of the second pixel group along the first direction F1 are both greater than or equal to 15 micrometers.

[0152] The extended spacing edge 131 refers to a pixel edge disposed on the third sub-pixel 130 and used to increase the spacing between two adjacent third sub-pixels 130 along the first direction F1.

[0153] Thus, by setting the extended edge 131, the spacing between two adjacent third sub-pixels 130 along the first direction F1 can be increased, thereby enabling the spacing between two adjacent third sub-pixels 130 to meet the application requirements of fine metal mask (FMM), so as to use fine metal mask (FMM) to make pixel arrangement structure 100.

[0154] In some embodiments, the extension edge 131 is parallel to the second direction F2.

[0155] This makes it convenient to set the corresponding extension edge 131, and also facilitates the fabrication of the pixel arrangement structure 100 using a fine metal mask (FMM).

[0156] In some embodiments, two adjacent repeating unit groups are defined as follows: one repeating unit group has a target sub-pixel of the first sub-pixel 110, and this repeating unit group is defined as the first repeating unit group. The other repeating unit group has a target sub-pixel of the second sub-pixel 120, and this repeating unit group is defined as the second repeating unit group. The second virtual quadrilateral S2 corresponding to the first repeating unit group and the second virtual quadrilateral S2 corresponding to the second repeating unit group are configured to share sides.

[0157] It can be that, in the first repeating unit group and the second repeating unit group adjacent to each other along the first direction F1, the second virtual quadrilateral S2 corresponding to the first repeating unit group shares a second hypotenuse S21 with the second virtual quadrilateral S2 corresponding to the second repeating unit group.

[0158] Alternatively, in the first and second repeating unit groups adjacent to each other along the second direction F2, the second virtual quadrilateral S2 corresponding to the first repeating unit group shares a second short side S22 or a second long side S23 with the second virtual quadrilateral S2 corresponding to the second repeating unit group.

[0159] Thus, the second virtual quadrilateral S2 corresponding to two adjacent repeating unit groups are set to share the same side, which allows two adjacent repeating unit groups to share multiple sub-pixels, thereby improving the compactness of the pixel arrangement structure 100 and thus helping to improve the resolution of the display panel 10.

[0160] In some embodiments, the first sub-pixel 110 and the second sub-pixel 120 are alternately arranged along the first direction F1, and the first sub-pixel 110 and the second sub-pixel 120 are alternately arranged along the second direction F2, with the first direction and the second direction intersecting each other.

[0161] This allows for the regular arrangement of multiple repeating units, thereby improving the resolution of the display panel 10.

[0162] Optionally, in the first repeating unit group and the second repeating unit group adjacent to each other along the first direction F1, the second virtual quadrilateral S2 corresponding to the first repeating unit group is rotated 180 degrees to form a mirror symmetry with the second virtual quadrilateral S2 corresponding to the second repeating unit group.

[0163] This allows multiple third sub-pixels 130 in the first and second repeating unit groups to better achieve a balance or symmetry in color viewing angles, thereby effectively reducing the risk of color shift in the display panel 10 and improving the display effect of the display panel 10.

[0164] Optionally, the second virtual quadrilaterals corresponding to the first and second repeating unit groups adjacent along the second direction F2 are mirror-symmetric.

[0165] Thus, the multiple third sub-pixels 130 in the first and second repeating unit groups adjacent to each other along the second direction F2 are symmetrically distributed, which helps the multiple third sub-pixels 130 to better generate color viewing angle balance or symmetry, thereby effectively reducing the color deviation risk of the display panel 10 and improving the display effect of the display panel 10.

[0166] In some embodiments, the first sub-pixel 110 has a first axis of symmetry Z1 parallel to the first direction F1, and the second sub-pixel 120 has a second axis of symmetry Z2 parallel to the first direction F1. The line connecting the center of the first sub-pixel 110 and the center of the second sub-pixel 120 intersects the first direction F1.

[0167] In the first sub-pixel 110 and the second sub-pixel 120 adjacent along the first direction F1, the first axis of symmetry Z1 of the first sub-pixel 110 and the second axis of symmetry Z2 of the second sub-pixel 120 are spaced apart along the second direction; the first direction F1 and the second direction F2 intersect each other.

[0168] Optionally, the first direction F1 and the second direction F2 are perpendicular to each other.

[0169] Optionally, the first sub-pixel 110 has a third axis of symmetry Z3 parallel to the second direction F2, and the second sub-pixel 120 has a fourth axis of symmetry Z4 parallel to the second direction F2.

[0170] In the first sub-pixel 110 and the second sub-pixel 120 adjacent to each other along the second direction F2, the third axis of symmetry Z3 of the first sub-pixel 110 coincides with the fourth axis of symmetry Z4 of the second sub-pixel 120.

[0171] In the second direction F2, the center of the first sub-pixel 110 and the center of the second sub-pixel 120 are on a straight line.

[0172] Optionally, the third sub-pixel 130 has a fifth axis of symmetry parallel to the first direction F1, and the fifth axes of symmetry of at least two adjacent third sub-pixels 130 along the first direction F1 coincide with each other.

[0173] Optionally, the third sub-pixel 130 has a sixth axis of symmetry parallel to the second direction F2, and at least two adjacent third sub-pixels 130 are spaced apart along the first direction F1 along the sixth axis of symmetry.

[0174] In this way, the two adjacent third sub-pixels 130 in the same column are staggered along the first direction F1, which can effectively improve the color edge problem.

[0175] In some embodiments, the first sub-pixel 110 includes four first pixel edges 111 arranged around the center of the first sub-pixel 110, and the first sub-pixel 110 also includes at least one first rounded pixel edge 112, and a first rounded pixel edge 112 is provided between at least two adjacent first pixel edges 111.

[0176] For example, the first sub-pixel 110 also includes four first rounded corner pixel edges 112, with a first rounded corner pixel edge 112 provided between any two adjacent first pixel edges 111.

[0177] In this way, a smooth transition can be achieved for the first sub-pixel 110 at the first rounded corner pixel edge 112, thereby improving the jagged edge problem at the first rounded corner pixel edge 112.

[0178] In some embodiments, the second sub-pixel 120 includes four second pixel edges 121 arranged around the center of the second sub-pixel 120, and the second sub-pixel 120 also includes at least one second rounded pixel edge 122, and a second rounded pixel edge 122 is provided between at least one pair of adjacent second pixel edges 121.

[0179] For example, the second sub-pixel 120 also includes four second rounded pixel edges 122, with a second rounded pixel edge 122 provided between any two adjacent second pixel edges 121.

[0180] In this way, a smooth transition can be achieved for the second sub-pixel 120 at the second rounded corner pixel edge 122, thereby improving the jagged edge problem at the second rounded corner pixel edge 122.

[0181] In some embodiments, the third sub-pixel 130 includes four third pixel edges 132 arranged around the center of the third sub-pixel 130, and the third sub-pixel 130 also includes at least one third rounded pixel edge 133, and a third rounded pixel edge 133 is provided between at least one pair of adjacent third pixel edges 132.

[0182] It can be, such as Figure 3 As shown, the third sub-pixel 130 also includes four third rounded corner pixel edges 133, with a third rounded corner pixel edge 133 provided between any two adjacent third pixel edges 132.

[0183] It could also be, such as Figure 5 As shown, the third sub-pixel 130 also includes two extended edges 131 spaced apart along the first direction F1, and two third rounded pixel edges 133 spaced apart along the second direction F2. The third rounded pixel edges 133 are connected between two adjacent third pixel edges 132 arranged along the first direction F1, and the extended edges 131 are connected between two adjacent third pixel edges 132 arranged along the second direction F2.

[0184] In this way, a smooth transition can be achieved at the third sub-pixel 130 at the third rounded corner pixel edge 133, thereby improving the jagged edge problem at the third rounded corner pixel edge 133.

[0185] Furthermore, the third sub-pixel 130 forms a chamfer at the extended edge 131, which helps to increase the spacing between two adjacent third sub-pixels 130 along the first direction F1, thereby facilitating the fabrication of the pixel arrangement structure 100 using a fine metal mask (FMM).

[0186] In some embodiments, the target sub-pixel includes four target pixel edges arranged around the center of the target sub-pixel, and the third sub-pixel 130 includes a third pixel edge 132 arranged opposite to the target pixel edge. In the repeating unit group, the spacing between the third pixel edge 132 of the four third sub-pixels 130 and the corresponding target pixel edge is equal.

[0187] It can be that the target sub-pixel is the first sub-pixel 110, and the target pixel edge is the first pixel edge 111 of the first sub-pixel 110. In this way, in the repeating unit group, the spacing between the third pixel edge 132 of the four third sub-pixels 130 and the corresponding first pixel edge 111 is equal, that is, L1 = L2 = L3 = L4.

[0188] Alternatively, the target sub-pixel is the second sub-pixel 120, and the target pixel edge is the second pixel edge 121 of the second sub-pixel 120. In this way, in the repeating unit group, the spacing between the third pixel edge 132 of the four third sub-pixels 130 and the corresponding second pixel edge 121 is equal, that is, L5 = L6 = L7 = L8.

[0189] In some embodiments, the shape of the first sub-pixel 110 is the same as the shape of the second sub-pixel 120.

[0190] Optionally, the shapes of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 are the same, for example, all of them are rectangular or rounded rectangles.

[0191] This makes the production and design of photomasks easier.

[0192] Optionally, the shape of the first sub-pixel 110 is selected from one of the following: ellipse, circle, sector, dumbbell, pear, quadrilateral, polygon, rectangle-like shape, rounded rectangle, star, and heart.

[0193] Optionally, the shape of the second sub-pixel 120 is selected from one of the following: ellipse, circle, sector, dumbbell, pear, quadrilateral, polygon, rectangle-like shape, rounded rectangle, star, and heart.

[0194] Optionally, the shape of the third sub-pixel 130 is selected from one of the following: ellipse, circle, sector, dumbbell, pear, quadrilateral, polygon, rectangle-like shape, rounded rectangle, star, and heart.

[0195] In some embodiments, the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 emit different colors.

[0196] Optionally, one of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 emits light in red, another of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 emits light in green, and yet another of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 emits light in blue.

[0197] In this way, color display can be achieved on display panel 10.

[0198] The second sub-pixel 120 emits blue light, and its light-emitting area is larger than that of the first sub-pixel 110 and also larger than that of the third sub-pixel 130.

[0199] Since blue sub-pixels have a longer lifespan, setting the light-emitting area of ​​the second sub-pixel 120 to be larger than that of the first sub-pixel 110 and larger than that of the third sub-pixel 130 is beneficial to improving the overall lifespan of the pixel arrangement structure 100, thereby improving the lifespan of the display panel 10.

[0200] Optionally, the third sub-pixel 130 emits green light and the first sub-pixel 110 emits red light. The third sub-pixel 130 can be set to a sub-pixel of a color that is sensitive to the human eye, such as a green sub-pixel. Each green sub-pixel can be surrounded by red and blue sub-pixels, thereby making the color mixing more uniform and improving the color deviation.

[0201] Figure 6 A schematic cross-sectional view of the display panel 10 at the first section J is shown in one embodiment of this application.

[0202] Please see Figure 6 One embodiment of this application provides a display device, including a display panel 10. The display panel 10 includes a substrate 200, a pixel arrangement structure 100 of any of the above embodiments, an encapsulation layer 400, and a touch layer 500. The pixel arrangement structure 100 is disposed on one side of the substrate 200, the encapsulation layer 400 is disposed on one side of the substrate 200 and covers the pixel arrangement structure 100, and the touch layer 500 is disposed on the side of the encapsulation layer 400 away from the substrate 200.

[0203] Optionally, the encapsulation layer 400 includes a first encapsulation layer 410 and a second encapsulation layer 420 stacked together. The first encapsulation layer 410 covers the pixel arrangement structure 100, and the second encapsulation layer 420 is disposed on the side of the first encapsulation layer 410 away from the substrate 200.

[0204] The pixel arrangement structure 100 can be encapsulated by the encapsulation layer 400 to reduce moisture intrusion, thereby improving the display effect of the display panel 10. The orthographic projection of the touch circuit of the touch layer 500 on the substrate 200 is staggered from the pixel arrangement structure 100 on the substrate 200. Moreover, the pattern formed by the touch circuit of the touch layer 500 and the pattern formed by the pixel arrangement structure 100 are similar to complementary patterns. Therefore, symmetrically arranging the third sub-pixels 130 of the four repeating units in the repeating unit group with the target sub-pixel as a reference object is beneficial to improving the symmetry of the touch circuit of the touch layer 500 corresponding to the position of the third sub-pixel 130. This is beneficial to improving the color shift problem caused by the asymmetrical design of the touch circuit of the touch layer 500, thereby improving the display effect of the display panel 10.

[0205] Optionally, the display panel 10 also includes a pixel definition layer 300, which has a plurality of pixel openings 301. The pixel openings 301 are corresponding to a plurality of sub-pixels of the pixel arrangement structure 100, that is, the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 of the pixel arrangement structure 100 are respectively located in the corresponding pixel openings 301.

[0206] Optionally, the pixel opening 301 is configured to correspond one-to-one with the sub-pixels of the pixel arrangement structure 100.

[0207] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0208] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
