Pixel arrangement structure, display panel and display device

Abstract

Embodiments of the present application disclose a pixel arrangement structure, a display panel, and a display device. In this pixel arrangement structure, in the arrangement direction of pixel units, the included angle between the third sub-pixel and the first sub-pixel and the second sub-pixel adjacent to it in the first direction is an obtuse angle, which is gentler compared with the right angle of the included angle between the green sub-pixel and the adjacent red sub-pixel and blue sub-pixel in the currently common pixel arrangement structure, thereby reducing the jaggedness and improving the display effect. Further, the side length of the virtual rectangle corresponding to each pixel unit in the arrangement direction of the pixel units straddles the third sub-pixel with the center located within the virtual rectangle, so that the first sub-pixel, the second sub-pixel, and the second sub-pixel are evenly arranged and have equal numbers in the display edge area, effectively improving the edge color deviation in the display edge area and further improving the display effect.

Description

Technical Field

[0001] The present application relates to the field of display technologies, and in particular, to a pixel arrangement structure, a display panel, and a display device. Background Art

[0002] Organic Light-Emitting Diode (OLED) display panels have become one of the current mainstream display panels due to their excellent characteristics such as high contrast ratio, thin thickness, wide viewing angle, fast response speed, being applicable to flexible panels, wide operating temperature range, and relatively simple structure and manufacturing process.

[0003] In OLED displays, the pixel arrangement has a very significant impact on the actual display effect. Currently, the commonly used pixel arrangements have serious defects such as severe jaggedness. Summary of the Invention

[0004] To solve the above technical problems, embodiments of the present application provide a pixel arrangement structure, a display panel, and a display device to reduce the jagged feeling in OLED displays and improve the display effect.

[0005] To achieve the above object, embodiments of the present application provide the following technical solutions:

[0006] A pixel arrangement structure includes: pixel rows arranged in parallel along a first direction, the first direction being parallel to the plane where the pixel arrangement structure is located;

[0007] Each of the pixel rows includes repeatedly arranged pixel units. Each pixel unit includes two first sub-pixels, two second sub-pixels, and one third sub-pixel. The connecting line of the centers of the two first sub-pixels and the centers of the two second sub-pixels forms a virtual rectangle. The two first sub-pixels are respectively located at both ends of a diagonal of the virtual rectangle, the two second sub-pixels are respectively located at both ends of the other diagonal of the virtual rectangle, and the center of the third sub-pixel is located inside the virtual rectangle;

[0008] In each pixel unit, two opposite sides of the virtual rectangle are parallel to the first direction, and the other two opposite sides of the virtual rectangle are perpendicular to the first direction. In the first direction, the included angle between the third sub-pixel and the adjacent first sub-pixel and second sub-pixel is an obtuse angle;

[0009] In each pixel row, adjacent pixel units share one first sub-pixel and one second sub-pixel, and the third sub-pixels in adjacent pixel units are separated by one first sub-pixel and one second sub-pixel shared by the adjacent pixel units.

[0010] Compared with the prior art, the above technical solutions have the following advantages:

[0011] In the currently common pixel arrangement structure, in the arrangement direction of pixel units, the included angle between the green sub-pixel and the adjacent red sub-pixel and blue sub-pixel is a right angle. In contrast, in the pixel arrangement structure provided by the embodiments of the present application, in the arrangement direction of pixel units (i.e., the first direction), the included angle between the third sub-pixel and the first sub-pixel and the second sub-pixel adjacent to it in the first direction is an obtuse angle, which is gentler than a right angle, thereby reducing the jagged feeling and improving the display effect.

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0025] Secondly, the present application is described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present application, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples, which should not limit the protection scope of the present application herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0026] As described in the background art section, in OLED displays, the pixel arrangement has a very significant impact on the actual display effect. The currently common pixel arrangement has serious defects such as severe jaggedness.

[0027] FIG. 1(a) shows a schematic structural diagram of the currently common pixel arrangement, and FIG. 1(b) shows a schematic structural diagram of a pixel unit in the currently common pixel arrangement. As shown in FIGS. 1(a) and 1(b), in the currently common pixel arrangement, a pixel unit includes two red sub-pixels 01, two blue sub-pixels 02, and one green sub-pixel 03, and the geometric shapes of the red sub-pixel 01, the blue sub-pixel 02, and the green sub-pixel 03 are all rectangles. Among them, the two red sub-pixels 01 are respectively located on the opposite sides of the green sub-pixel 03, and the two blue sub-pixels 02 are respectively located on the other two opposite sides of the green sub-pixel 03.

[0028] The inventors have found through research that since each sub-pixel of a pixel unit in the currently common pixel arrangement is a rectangle, therefore, as indicated by the thick black line in FIG. 1(b), the included angle between the green sub-pixel 03 and the adjacent red sub-pixel 01 and blue sub-pixel 02 is a right angle, resulting in serious jaggedness defects in the arrangement direction of the pixel units, specifically in the horizontal, vertical, and oblique directions, as indicated by the thick black line in FIG. 1(a).

[0029] In view of this, an embodiment of the present application provides a pixel arrangement structure 100, as Figure 2 shown. The pixel arrangement structure 100 includes pixel rows 110 arranged in parallel along a first direction, and the first direction is parallel to the plane where the pixel arrangement structure is located;

[0030] Each of the pixel rows 110 includes pixel units 111 arranged repeatedly, Figure 3 shows a schematic structural diagram of a pixel unit in the pixel arrangement structure provided by the embodiment of the present application. Combining Figure 2 and Figure 3 shown, each of the pixel units 111 includes two first sub-pixels 10, two second sub-pixels 20, and one third sub-pixel 30. The center connection lines of the two first sub-pixels 10 and the two second sub-pixels 20 form a virtual rectangle 40, and the two first sub-pixels 10 are respectively located at both ends of a diagonal of the virtual rectangle 40, and the two second sub-pixels 20 are respectively located at both ends of the other diagonal of the virtual rectangle 40. The center of the third sub-pixel 30 is located inside the virtual rectangle 40;

[0031] In each of the pixel units 111, two opposite sides of the virtual rectangle 40 are parallel to the first direction, and the other two opposite sides of the virtual rectangle 40 are perpendicular to the first direction. In the first direction, the included angle between the third sub-pixel 30 and the adjacent first sub-pixel 10 and second sub-pixel 20 is an obtuse angle;

[0032] In each of the pixel rows 110, adjacent pixel units 111 share one first sub-pixel 10 and one second sub-pixel 20, and the third sub-pixels 30 in adjacent pixel units 111 are separated by one first sub-pixel 10 and one second sub-pixel 20 shared by the adjacent pixel units 111.

[0033] It should be noted that in the pixel arrangement structure provided by the embodiment of the present application, the pixel rows 110 are arranged in parallel along the first direction, and each pixel row 110 includes pixel units 111 arranged repeatedly, that is, the pixel units 111 are arranged repeatedly along the first direction to form the pixel row 110. Among them, the first direction can be the horizontal direction of the plane where the pixel arrangement structure is located, such as Figure 2 shown in the horizontal direction, or the vertical direction of the plane where the pixel arrangement structure is located, such as Figure 2 shown in the vertical direction, or the oblique direction of the plane where the pixel arrangement structure is located, such as Figure 2 shown in the oblique direction. The present application does not make any limitations on this, and it depends on the specific situation.

[0034] It should also be noted that the center of the first sub-pixel 10 is the geometric center of the shape of the first sub-pixel. For example, asFigure 2 As shown, the shape of the first sub-pixel 10 is a regular pentagon, and the center of the first sub-pixel 10 is the intersection of the angle bisectors of any two angles of the regular pentagon. Similarly, the center of the second sub-pixel 20 is the geometric center of the shape of the second sub-pixel, and the center of the third sub-pixel 30 is the geometric center of the shape of the third sub-pixel.

[0035] In each pixel unit 111, the connection lines between the centers of two first sub-pixels 10 and the centers of two second sub-pixels 20 form a virtual rectangle 40. The two first sub-pixels 10 are respectively located at both ends of a diagonal of the virtual rectangle 40, and the two second sub-pixels 20 are located at both ends of the other diagonal of the virtual rectangle 40. The center of the third sub-pixel 30 is located inside the virtual rectangle 40. Moreover, two opposite sides of the virtual rectangle 40 are parallel to the first direction, and the other two opposite sides of the virtual rectangle 40 are perpendicular to the first direction. That is to say, as Figure 2 shown, in each pixel unit 111, the connection line between the center of a first sub-pixel 10 and the center of a second sub-pixel 20 along the first direction forms one side length of the virtual rectangle 40 along the first direction, and the connection line between the center of this first sub-pixel 10 and the center of another second sub-pixel 20 constitutes one side length of the virtual rectangle 40 perpendicular to the first direction.

[0036] Since each pixel row 110 is arranged parallel to the first direction, therefore, as Figure 2 shown, the connection lines between the centers of the first sub-pixels 10 of a pixel unit 111 in the i-th pixel row 110 and the centers of the first sub-pixels 10 of the pixel unit 111 adjacent to and arranged in the same way in the (i + 1)-th pixel row form a parallelogram, where i is an integer not less than 1. Similarly, as Figure 2 shown, the connection lines between the centers of the second sub-pixels 20 of a pixel unit 111 in the i-th pixel row 110 and the centers of the second sub-pixels 20 of the pixel unit 111 adjacent to and arranged in the same way in the (i + 1)-th pixel row also form a parallelogram.

[0037] This application does not limit the arrangement manner of adjacent pixel rows 110. Optionally, in one embodiment of this application, two adjacent pixel rows 110 are exactly the same; optionally, in another embodiment of this application, two adjacent pixel rows 110 are arranged in a staggered manner. In addition, this application does not limit whether the first sub-pixel 10 and / or the second sub-pixel 20 are shared between adjacent pixel rows 110, which depends on the specific situation.

[0038] It should be further noted that the area of the geometric shape of the first sub-pixel 10 is larger than the area of its actual light-emitting unit. For example, as Figure 2As shown, the geometry of the first sub-pixel 10 is a regular pentagon, which contains a small pentagon. This small pentagon is the actual light-emitting unit of the first sub-pixel, and the area of the geometry of the first sub-pixel is the area of the large pentagon that encloses this small pentagon. This is because in the actual process, design margins need to be left for the mask, and these margin parts do not actually emit light. Then, combined with Figure 2 and Figure 3 shown, in each pixel unit 111, the included angle between the third sub-pixel 30 and the first sub-pixel 10 and the second sub-pixel 20 adjacent to it in the first direction is an obtuse angle. Specifically, the included angle between the light-emitting unit of the third sub-pixel 30 and the light-emitting units of the first sub-pixel 10 and the second sub-pixel 20 adjacent to it in the first direction is an obtuse angle.

[0039] For example, as Figure 3 shown, in a pixel unit 111, the point closest to the left side of the light-emitting unit of the third sub-pixel 30 is set as point O, the point closest to the left side of the light-emitting unit of the first sub-pixel 10 adjacent to the third sub-pixel 30 in the first direction is set as point A, and the point closest to the left side of the light-emitting unit of the second sub-pixel 20 adjacent to the third sub-pixel 30 in the first direction is set as point B. At this time, in the first direction, the line connecting the centers of the first sub-pixel 10 adjacent to the third sub-pixel 30 and the second sub-pixel 20 adjacent to the third sub-pixel 30 is parallel to the first direction and is a side length of the virtual rectangle 40 in the first direction. Then, the included angle between the light-emitting unit of the third sub-pixel 30 and the light-emitting units of the first sub-pixel 10 and the second sub-pixel 20 adjacent to it in the first direction is ∠AOB, and this included angle ∠AOB is an obtuse angle, thereby reducing the jagged feeling and improving the display effect.

[0040] Of course, in each pixel unit 111, the included angle between the light-emitting unit of the third sub-pixel 30 and the light-emitting units of the first sub-pixel 10 and the second sub-pixel 20 adjacent to it in the first direction is not necessarily as Figure 3As shown in [figures], the included angles between point O at the leftmost side of the light-emitting unit of the third sub-pixel 30, point A at the leftmost side of the light-emitting unit of the first sub-pixel 10 adjacent to it in the first direction, and point B at the leftmost side of the light-emitting unit of the second sub-pixel 20 adjacent to it in the first direction, as long as the two rays emitted from point O at the leftmost side of the light-emitting unit of the third sub-pixel 30 just touch the light-emitting units of the first sub-pixel 10 and the second sub-pixel 20 adjacent to the third sub-pixel 30 in the first direction respectively, the included angle formed by these two rays emitted from point O at the leftmost side of the light-emitting unit of the third sub-pixel 30 is the said opening angle. At this time, the light-emitting unit of the third sub-pixel 30, the light-emitting unit of the first sub-pixel 10 adjacent to it in the first direction, and the light-emitting unit of the second sub-pixel 20 are all located outside the said opening angle.

[0041] And, Figure 2 and Figure 3 Both are described by taking the light-emitting unit of the third sub-pixel 30 as a quadrilateral with only one vertex O at the leftmost side of this quadrilateral as an example. Obviously, this application does not limit this. When there is not one vertex but a line segment or multiple vertices at the leftmost side of the light-emitting unit of the third sub-pixel 30, a suitable point on the light-emitting unit of the third sub-pixel 30 can be selected as point O according to the actual situation, so that the opening angle between point O on the light-emitting unit of the third sub-pixel 30 and the light-emitting units of the first sub-pixel 10 and the second sub-pixel 20 adjacent to the third sub-pixel 30 in the first direction is an obtuse angle, thereby reducing the jagged feeling and improving the display effect.

[0042] It can be seen that compared with the general pixel arrangement structure currently in use, in the arrangement direction of pixel units, the opening angle between the green sub-pixel and the adjacent red sub-pixel and blue sub-pixel is a right angle. In the pixel arrangement structure provided by the embodiment of this application, in the arrangement direction of pixel units (i.e., the first direction), the opening angle between the third sub-pixel and the first sub-pixel and the second sub-pixel adjacent to it in the first direction is an obtuse angle, which is gentler than a right angle, thereby reducing the jagged feeling and improving the display effect.

[0043] Based on the above embodiments, optionally, in an embodiment of this application, both the first sub-pixel 10 and the second sub-pixel 20 are polygons with the number of side lengths not less than 5, and the third sub-pixel 30 is a quadrilateral or a hexagon. For example, as Figure 2 and Figure 3 shown, both the first sub-pixel 10 and the second sub-pixel 20 are pentagons; as Figure 4 shown, both the first sub-pixel 10 and the second sub-pixel 20 are hexagons; as Figure 5 shown, both the first sub-pixel 10 and the second sub-pixel 20 are octagons.

[0044] Optionally, asFigures 3 - 5 As shown, both the first sub-pixel 10 and the second sub-pixel 20 are regular polygons.

[0045] Optionally, in another embodiment of the present application, both the first sub-pixel 10 and the second sub-pixel 20 are circular or elliptical, and the third sub-pixel 30 is quadrilateral or hexagonal. Optionally, as Figure 6 shown, both the first sub-pixel 10 and the second sub-pixel 20 are circular.

[0046] Based on any of the above embodiments, optionally, in an embodiment of the present application, the first sub-pixel 10 and the second sub-pixel 20 have the same shape.

[0047] Based on any of the above embodiments, optionally, in an embodiment of the present application, as Figures 3 - 6 shown, in each pixel unit, the center of the third sub-pixel 30 coincides with the center of the virtual rectangle 40.

[0048] It should be noted that in the above embodiments, when the first sub-pixel 10 and the second sub-pixel 20 are polygons with a side number of not less than 5, circular or elliptical, and the third sub-pixel 30 is quadrilateral or hexagonal, then, when the polygon, circular or elliptical first sub-pixel 10, the polygon, circular or elliptical second sub-pixel 20, and the quadrilateral or hexagonal third sub-pixel 30 are combined to form the pixel unit 111, because the interior angles of each sub-pixel are small, the exterior angles after splicing are large, so that the jagged feeling can be reduced. Specifically, refer to Figure 2 shown. It can be seen from the figure that whether in the first direction, the direction perpendicular to the first direction, or the obliquely upward direction intersecting the first direction, the jagged feeling of the line display is reduced.

[0049] Furthermore, the inventor has found through research that in the currently common pixel arrangement structure, as shown in Fig. 1(a), in the display edge area, specifically in the leftmost and bottommost areas of the pixel arrangement structure in Fig. 1(a), since the center connection line of the red sub-pixel 01 and the blue sub-pixel 02 is parallel to the pixel unit arrangement direction, and the green sub-pixel 03 is located inside the center connection line of the red sub-pixel 01 and the blue sub-pixel 02, therefore, edge color deviation will occur in the display edge area, affecting the display effect; similarly, in the topmost and rightmost areas of the pixel arrangement structure in Fig. 1(a), since the center connection line of the red sub-pixel 01 and the blue sub-pixel 02 is parallel to the pixel unit arrangement direction, and the green sub-pixel 03 is located outside the center connection line of the red sub-pixel 01 and the blue sub-pixel 02, therefore, edge color deviation will also occur in the display edge area, affecting the display effect.

[0050] In view of this, optionally, in an embodiment of the present application, continue as Figure 2 and Figure 3 shown, the side length of the virtual rectangle 40 along the first direction straddles the third sub-pixel 30 with the center located within the virtual rectangle 40. At this time, in the pixel unit arrangement direction (i.e., in the first direction), the first sub-pixel 10, the third sub-pixel 30, and the second sub-pixel 20 are arranged in sequence. Thus, in the display edge area, the first sub-pixel 10, the second sub-pixel 30, and the second sub-pixel 20 are evenly arranged and have equal numbers, effectively improving the edge color deviation in the display edge area and enhancing the display effect.

[0051] As known from the foregoing, the present application does not limit the arrangement manner of adjacent pixel rows 110. However, considering that edge color deviation may occur not only in the pixel unit arrangement direction (i.e., the first direction) but also in the direction perpendicular to the first direction. In the direction perpendicular to the first direction, if the pixel rows 110 are completely arranged repeatedly, then, in the display edge area perpendicular to the first direction, the phenomenon of alternating arrangement of the first sub-pixel 10 and the second sub-pixel 20 will occur, resulting in edge color deviation. Therefore, further, optionally, in an embodiment of the present application, as Figure 2 and Figure 3 shown, the centers of the virtual rectangles 40 corresponding to one pixel unit 111 in the i-th pixel row 110 and the centers of the virtual rectangles 40 corresponding to an adjacent pixel unit 111 in the (i + 1)-th pixel row 110 are not on a virtual straight line along the second direction. The second direction is parallel to the plane where the pixel arrangement structure is located, and the second direction is perpendicular to the first direction, and i is an integer not less than 1.

[0052] That is to say, the centers of the virtual rectangles 40 corresponding to one pixel unit 111 in the i-th pixel row 110 and the centers of the virtual rectangles 40 corresponding to an adjacent pixel unit 111 in the (i + 1)-th pixel row 110 are located on both sides of a virtual straight line along the second direction, that is, the virtual rectangles 40 corresponding to one pixel unit 111 in the i-th pixel row 110 and the virtual rectangles 40 corresponding to an adjacent pixel unit 111 in the (i + 1)-th pixel row 110 are not arranged completely repeatedly along the second direction but are arranged in a staggered manner in the second direction. Thus, in the second direction, the first sub-pixel 10 and the second sub-pixel 20 of one pixel unit 111 in the i-th pixel row 110 and the third sub-pixel 30 of an adjacent pixel unit 111 in the (i + 1)-th pixel row 110 are arranged in sequence. Furthermore, in the second direction, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are arranged in sequence, improving the edge color deviation in the display edge area along the second direction and enhancing the display effect.

[0053] Among them, this application does not limit the order in which the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are arranged in sequence along the second direction. Specifically, as Figure 2 shown, for the first row, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are arranged in sequence along the second direction; for the second row, the third sub-pixel 30, the second sub-pixel 20, and the first sub-pixel 10 are arranged in sequence along the second direction; for the third row, the second sub-pixel 20, the first sub-pixel 0, and the third sub-pixel 30 are arranged in sequence; for the fourth row, the third sub-pixel 30, the first sub-pixel 10, and the second sub-pixel 20 are arranged in sequence.

[0054] Based on the above embodiments, optionally, in an embodiment of this application, as Figure 2 shown, in the second direction, the centers of the first sub-pixel 10 and the second sub-pixel 20 of a pixel unit 111 in the i-th pixel row 110 and the center of the third sub-pixel 30 of a pixel unit 111 adjacent to this pixel unit in the (i + 1)-th pixel row 110 are located on a virtual straight line along the second direction, so as to further improve the uniformity of the arrangement of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 in sequence along the second direction, further eliminate edge color deviation, and improve the display effect.

[0055] Based on the above embodiments, optionally, in an embodiment of this application, as Figure 2 shown, the i-th pixel row and the (i + 2)-th pixel row are arranged repeatedly, so as to divide each pixel row into only two categories, while improving the sawtooth defect and the edge color deviation defect, and simplifying the process steps.

[0056] Based on the above embodiments, optionally, in an embodiment of this application, as Figure 7 shown, in each pixel unit 111, the third sub-pixel 30 is axisymmetric about the first virtual straight line 50, the first virtual straight line 50 is a virtual straight line parallel to the first direction and passing through the center of the virtual rectangle 40, and the first sub-pixel 10 and the second sub-pixel 20 on one side of the third sub-pixel 30 are also axisymmetric about the first virtual straight line 50, and the first sub-pixel 10 and the second sub-pixel 20 on the other side of the third sub-pixel 30 are also axisymmetric about the first virtual straight line 50.

[0057] Based on the above embodiments, optionally, in an embodiment of this application, as Figure 7As shown, in each of the pixel units 111, the third sub-pixel 30 includes a first side length 31 and a second side length 32 that are connected to each other and symmetric about the first virtual line 50, and a third side length 33 and a fourth side length 34 that are connected to each other and symmetric about the axis of the first virtual line 50. The first side length 31 and the third side length 33 are symmetric about the second virtual line 60, and the second side length 32 and the fourth side length 34 are also symmetric about the second virtual line 60. The second virtual line 60 is a virtual line perpendicular to the first direction and passing through the center of the virtual rectangle 40.

[0058] In each of the pixel units 111, two of the first sub-pixels 10 are respectively in contact with the first side length 31 and the fourth side length 34 of the third sub-pixel 30, and two of the second sub-pixels 20 are respectively in contact with the second side length 32 and the third side length 33 of the third sub-pixel 30.

[0059] Since in each pixel row 110, adjacent pixel units 111 share a first sub-pixel 10 and a second sub-pixel 20, and the third sub-pixels 30 in adjacent pixel units 111 are separated by a first sub-pixel 10 and a second sub-pixel 20 shared by the adjacent pixel units, therefore, as Figure 2 shown, in a pixel unit 111, the side length of the virtual rectangle 40 in the first direction needs to span the third sub-pixel 30, while the side length of the virtual rectangle 40 perpendicular to the first direction may not need to span the third sub-pixel 30. In order to further make the arrangement of the pixel units 111 in the pixel arrangement structure 100 more compact and improve the display effect, on the basis of any of the above embodiments, optionally, in an embodiment of the present application, the side length of the virtual rectangle 40 in the first direction is greater than the side length of the virtual rectangle 40 perpendicular to the first direction.

[0060] Specifically, in an embodiment of the present application, the side length of the virtual rectangle 40 in the first direction is twice the side length of the virtual rectangle 40 perpendicular to the first direction, so as to achieve a better display ratio.

[0061] On the basis of any of the above embodiments, optionally, in an embodiment of the present application, the first sub-pixel 10 is a red sub-pixel, the second sub-pixel 20 is a blue sub-pixel, and the third sub-pixel 30 is a green sub-pixel.

[0062] Optionally, in another embodiment of the present application, the first sub-pixel 10 is a blue sub-pixel, the second sub-pixel 20 is a red sub-pixel, and the third sub-pixel 30 is a green sub-pixel.

[0063] To more clearly show the display effect of the pixel arrangement structure provided by the embodiments of the present application,Figure 8 FIG. 0 shows an overall schematic diagram of the pixel arrangement structure provided by the embodiments of the present application. As Figure 8 shown, the first sub-pixel 10 and the second sub-pixel 20 can both be polygons, circles or ellipses with a side length of not less than 5, and the third sub-pixel 30 can be a quadrilateral or a hexagon, so that in each pixel unit 111, the included angle between the third sub-pixel 30 and the first sub-pixel 10 and the second sub-pixel 20 adjacent to it in the first direction is an obtuse angle, thereby reducing the jagged feeling and improving the display effect when displaying horizontal lines, vertical lines and diagonal lines; and, the pixel rows are arranged in a staggered manner, so that no matter in the row direction or the column direction, as Figure 8 shown, the pixels in the outermost edge area are evenly arranged with the first sub-pixel, the second sub-pixel and the third sub-pixel, and the numbers are equal, thereby greatly reducing color cast in the display edge area and further improving the display effect; in addition, from Figure 8 it can also be seen that the pixel units are closely arranged, which can also improve the space utilization rate and make the display ratio better.

[0064] The embodiments of the present application further provide a display panel 200, including the pixel arrangement structure described in any one of the above, wherein the plane where the pixel arrangement structure is located is parallel to the plane where the display panel is located.

[0065] The embodiments of the present application further provide a display device. As Figure 9 shown, the display device 300 includes the above display panel 200. The display device can be any electronic device with a display function, such as a touch display screen, a mobile phone, a tablet computer, a notebook computer, an e-book or a television, etc.

[0066] In summary, in the pixel arrangement structure provided by the embodiments of the present application, in the arrangement direction of the pixel units (i.e., the first direction), the included angle between the third sub-pixel and the first sub-pixel and the second sub-pixel adjacent to it in the first direction is an obtuse angle, which is more gentle than the right angle between the green sub-pixel and the adjacent red sub-pixel and blue sub-pixel in the currently common pixel arrangement structure, thereby reducing the jaggedness and improving the display effect. Further, the side length of the virtual rectangle corresponding to each pixel unit in the first direction straddles the third sub-pixel with the center located within the virtual rectangle, so that in the display edge area, the first sub-pixel, the second sub-pixel and the second sub-pixel are evenly arranged and the numbers are equal, effectively improving the edge color cast in the display edge area and further improving the display effect. Furthermore, adjacent pixel rows are arranged in a staggered manner to further improve the uniformity of the arrangement of the first sub-pixel, the second sub-pixel and the third sub-pixel in the second direction (perpendicular to the first direction), further eliminating the edge color cast and improving the display effect.
