[0090] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0091] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0092] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0093] Organic Light-Emitting Diode (OLED) display devices have been listed as a display technology with great development prospects due to their advantages such as thinness, lightness, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, wide operating temperature range, simple production process, high light emission efficiency and flexible display.

[0094] In the relevant pixel arrangement technology, the number ratio of R pixels, G pixels and B pixels is 1:2:1, wherein the center line of adjacent R pixels and B pixels is a trapezoid, the center line of adjacent G pixels is a square or trapezoid, and the G pixels are adjacent to the R pixels and B pixels. The R pixels, G pixels and B pixels of this pixel arrangement structure are arranged irregularly, resulting in low aperture ratio and distortion of horizontal and vertical lines, which in turn leads to poor display effect.

[0095] In view of at least one of the above problems, the embodiments of the present application provide a pixel arrangement structure and a display panel, by making the light-emitting areas of at least part of the first sub-pixel surround at least part of the light-emitting area of ​​the third sub-pixel in one-to-one correspondence, and making the light-emitting areas of at least part of the second sub-pixel surround at least part of the light-emitting area of ​​the third sub-pixel in one-to-one correspondence. In this way, the space around the third sub-pixel can be fully utilized, which is conducive to improving the aperture ratio and thus improving the display effect. In addition, by making the light-emitting areas of the first sub-pixel and / or the second sub-pixel surrounding the third sub-pixel separate the light-emitting areas of any two adjacent third sub-pixels, it is conducive to reducing the risk of color mixing and color deviation, and improving color fringing.

[0096] For a better understanding, some explanations are given before going into detail:

[0097] Sub-pixels: Sub-pixels are composed of small grids that display images. These small grids have a clear position and assigned color values, and the clear position is determined by the pixel arrangement, and the assigned color value is determined by the pixel circuit. The color and position of these small grids determine the appearance of the displayed image.

[0098] Resolution: Display resolution refers to the precision of the displayed image, specifically, how many sub-pixels the display can display. For example, common resolutions are HD: 720*1280, FHD: 1080*1920, QHD: 1440*2560, and UHD (2K\4K): 2160*3840. Taking FHD as an example, it means that there are 1080 R sub-pixels, 1080 G sub-pixels, and 1080 B sub-pixels in one direction, and 1920 R sub-pixels, 1920 G sub-pixels, and 1920 B sub-pixels in the other direction.

[0099] PPI (Pixels Per Inch): Also known as pixel density, it indicates the number of pixels in one inch. For example, FHD resolution and 5-inch size have 441 PPI. Therefore, it can be considered that under the premise that the size of the display is certain, the higher the resolution, the higher the PPI.

[0100] It should be pointed out that those skilled in the art should know that based on the pixel arrangement structure of the present application, each sub-pixel should be distributed as evenly as possible.

[0101] First, refer to Figure 1-Figure 6 As shown, an embodiment of the present application provides a pixel arrangement structure 100 , which includes a plurality of sub-pixels 111 , and the plurality of sub-pixels 111 include a plurality of first sub-pixels 1111 , a plurality of second sub-pixels 1112 , and a plurality of third sub-pixels 1113 .

[0102] Specifically, at least part of the light emitting area of ​​the first sub-pixel 1111 surrounds at least part of the light emitting area of ​​the third sub-pixel 1113. At least part of the light emitting area of ​​the second sub-pixel 1112 surrounds at least part of the light emitting area of ​​the third sub-pixel 1113.

[0103] The light-emitting areas of any two adjacent third sub-pixels 1113 are separated by the light-emitting areas of the first sub-pixel 1111 and / or the second sub-pixel 1112 surrounding the third sub-pixel 1113 .

[0104] Here, it should be noted that the light-emitting area of ​​the sub-pixel 111 can be understood as the effective light-emitting area of ​​the sub-pixel 111. Meanwhile, in one embodiment, only the light-emitting areas of a part of the first sub-pixels 1111 surround at least part of the light-emitting area of ​​the third sub-pixel 1113 in one-to-one correspondence, and the light-emitting areas of another part of the first sub-pixels 1111 do not surround the light-emitting area of ​​the third sub-pixel 1113. In one embodiment, only the light-emitting areas of a part of the second sub-pixels 1112 surround at least part of the light-emitting area of ​​the third sub-pixel 1113 in one-to-one correspondence, and the light-emitting areas of another part of the second sub-pixels 1112 do not surround the light-emitting area of ​​the third sub-pixel 1113. In one embodiment, no other sub-pixels 111 are arranged around the light-emitting areas of a part of the third sub-pixels 1113.

[0105] Here, “the light-emitting areas of any two adjacent third sub-pixels 1113 are separated by the light-emitting areas of the first sub-pixel 1111 and / or the second sub-pixel 1112 surrounding the third sub-pixel 1113” has the following three situations:

[0106] In an example, the light-emitting areas of any two adjacent third sub-pixels 1113 are separated by the light-emitting area of ​​the first sub-pixel 1111 surrounding one of the third sub-pixels 1113 .

[0107] In another example, the light-emitting areas of any two adjacent third sub-pixels 1113 are separated by the light-emitting area of ​​the second sub-pixel 1112 surrounding one of the third sub-pixels 1113 .

[0108] In yet another example, the light-emitting areas of any two adjacent third sub-pixels 1113 are separated by the light-emitting areas of the first sub-pixel 1111 and the second sub-pixel 1112 respectively surrounding the two third sub-pixels 1113 .

[0109] It can be understood that the pixel arrangement structure 100 includes a plurality of repeatedly arranged pixel groups 110, and each pixel group 110 includes a first sub-pixel 1111, a second sub-pixel 1112, and a third sub-pixel 1113. The pixel group 110 refers to: a minimum repeating unit repeatedly arranged in the pixel arrangement structure 100. The first sub-pixel 1111, the second sub-pixel 1112, and the third sub-pixel 1113 can be one of a red sub-pixel 111, a blue sub-pixel 111, and a green sub-pixel 111, respectively. Of course, in some other embodiments, the first sub-pixel 1111, the second sub-pixel 1112, and the third sub-pixel 1113 can also be sub-pixels 111 that emit light of other colors besides red, green, and blue, for example, white or yellow, which is not limited in the embodiments of the present application. In the embodiment of the present application, the first sub-pixel 1111 is a blue sub-pixel 111 , the second sub-pixel 1112 is a red sub-pixel 111 , and the third sub-pixel 1113 is a green sub-pixel 111 .

[0110] The pixel arrangement structure 100 provided in the embodiment of the present application makes the light-emitting areas of at least part of the first sub-pixel 1111 surround at least part of the light-emitting area of ​​the third sub-pixel 1113 in one-to-one correspondence, and makes the light-emitting areas of at least part of the second sub-pixel 1112 surround at least part of the light-emitting area of ​​the third sub-pixel 1113 in one-to-one correspondence. In this way, the space around the third sub-pixel 1113 can be fully utilized, which is conducive to improving the aperture ratio and further improving the display effect.

[0111] In addition, it should be noted that the green sub-pixel 111 is a sub-pixel 111 that is relatively sensitive to the human eye. If the green sub-pixels 111 are too close, the two green sub-pixels 111 are easily identified as one, resulting in a grainy display. In the embodiment of the present application, by making the light-emitting areas of the first sub-pixel 1111 and / or the second sub-pixel 1112 surrounding the third sub-pixel 1113 separate from the light-emitting areas of any two adjacent third sub-pixels 1113, the distance between adjacent green sub-pixels 111 can be appropriately increased, which can not only avoid the grainy display caused by the human eye being unable to distinguish and identifying the sensitive sub-pixels 111 as one during display, but also help reduce the risk of color mixing and color deviation, and improve color fringing.

[0112] In one embodiment, referring to Figure 1 , Figure 2 and Figure 3As shown, the light emitting area of ​​each first sub-pixel 1111 surrounds at least a portion of the light emitting area of ​​a corresponding third sub-pixel 1113. The light emitting area of ​​each second sub-pixel 1112 surrounds at least a portion of the light emitting area of ​​a corresponding third sub-pixel 1113.

[0113] In this way, all first sub-pixels 1111 and all second sub-pixels 1112 surround at least part of the light emitting area of ​​the corresponding third sub-pixel 1113. In this way, the space around the third sub-pixel 1113 can be further fully utilized, which is conducive to improving the aperture ratio and further improving the display effect.

[0114] Here, it should be noted that in one example, referring to Figure 1 and Figure 2 As shown, the light emitting area of ​​the first sub-pixel 1111 surrounds the outer periphery of a portion of the light emitting area of ​​the corresponding third sub-pixel 1113. The light emitting area of ​​the second sub-pixel 1112 surrounds the outer periphery of a portion of the light emitting area of ​​the corresponding third sub-pixel 1113.

[0115] Furthermore, if Figure 1 As shown, the light-emitting area of ​​the first sub-pixel 1111 may surround the corresponding third sub-pixel 1113 on both sides along the first direction X and on one side along the second direction Y. The light-emitting area of ​​the second sub-pixel 1112 surrounds the corresponding third sub-pixel 1113 on one side along the first direction X and on both sides along the second direction Y. Figure 2 As shown, the light-emitting area of ​​the first sub-pixel 1111 may surround the corresponding third sub-pixel 1113 on both sides along the first direction X, on one side along the second direction Y, and a portion of the other side along the second direction Y. The light-emitting area of ​​the second sub-pixel 1112 surrounds the corresponding third sub-pixel 1113 on both sides along the second direction Y, on one side along the first direction X, and a portion of the other side along the first direction X. The embodiment of the present application does not limit the manner in which the sub-pixels 111 surrounding the third sub-pixel 1113 are arranged.

[0116] In one embodiment, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the light-emitting area of ​​the sub-pixel 111 corresponding to each third sub-pixel 1113 surrounds the periphery of the entire light-emitting area of ​​the third sub-pixel 1113. It can be understood that the sub-pixel 111 corresponding to the third sub-pixel 1113 is the first sub-pixel 1111 or the second sub-pixel 1112, which is equivalent to setting the shape of the first sub-pixel 1111 and the second sub-pixel 1112 to a closed ring.

[0117] In this way, on the one hand, the light-emitting area of ​​the first sub-pixel 1111 and the second sub-pixel 1112 can be made larger, which is beneficial to improving the aperture ratio and thus improving the display effect. On the other hand, the first sub-pixel 1111 and the second sub-pixel 1112 are arranged between any two adjacent third sub-pixels 1113, and the distance between adjacent third sub-pixels 1113 can be appropriately increased, which can not only avoid the display graininess caused by the human eye's inability to distinguish the sensitive sub-pixels 111 and identifying them as one during display, but also help reduce the risk of color mixing and color deviation, and improve color fringing.

[0118] In one embodiment, referring to Figure 3 and Figure 4 As shown, a plurality of third sub-pixels 1113 are arranged in rows along a first direction X, and in columns along a second direction Y intersecting the first direction X. In any two adjacent third sub-pixels 1113 in the same row, the sub-pixels 111 surrounding the two third sub-pixels 1113 are the first sub-pixel 1111 and the second sub-pixel 1112, respectively.

[0119] In this way, in the sub-pixels 111 in the same row, the first sub-pixels 1111 and the second sub-pixels 1112 are arranged alternately, and a third sub-pixel 1113 is disposed inside each first sub-pixel 1111 and each second sub-pixel 1112 .

[0120] Further, in any two adjacent third sub-pixels 1113 in the same column, the sub-pixels 111 surrounding the two third sub-pixels 1113 are the first sub-pixel 1111 and the second sub-pixel 1112 .

[0121] In this way, in the sub-pixels 111 in the same column, the first sub-pixels 1111 and the second sub-pixels 1112 are arranged alternately, and a third sub-pixel 1113 is provided inside each first sub-pixel 1111 and each second sub-pixel 1112. In this way, the number of third sub-pixels 1113 can be real, the display effect can be guaranteed, and the color edge problem formed when the first sub-pixel 1111 and the second sub-pixel 1112 are located in the same row or the same column can be avoided.

[0122] In one embodiment, the centers of the third sub-pixels 1113 in the same row are all located on the same straight line, and the centers of the third sub-pixels 1113 in the same column are all located on the same straight line.

[0123] Here, the center of the third sub-pixel 1113 refers to the geometric center of the third sub-pixel 1113 .

[0124] The above configuration can make the light emitted by the third sub-pixel 1113 more uniform in the row direction and the column direction, thereby improving the display effect.

[0125] In one embodiment, the number of the first sub-pixels 1111 and the number of the second sub-pixels 1112 are equal, and the number of the third sub-pixels 1113 is equal to the sum of the number of the first sub-pixels 1111 and the second sub-pixels 1112 .

[0126] In this way, it is ensured that all third sub-pixels 1113 can be surrounded by the first sub-pixels 1111 and the second sub-pixels 1112 in a one-to-one correspondence.

[0127] In one embodiment, the ratio of the number of the first sub-pixel 1111 , the number of the second sub-pixel 1112 , and the number of the third sub-pixel 1113 is 1:1:2.

[0128] In this way, the number of the third sub-pixels 1113 can be made equal to the resolution, thereby improving the display effect.

[0129] In one embodiment, referring to Figure 3 As shown, the third sub-pixel 1113 has a first center line 121 passing through the center thereof and extending along the first direction X, and a second center line 122 passing through the center thereof and extending along the second direction Y. The light-emitting areas of the sub-pixels 111 surrounding the third sub-pixel 1113 are configured as an axisymmetric pattern with respect to the first center line 121.

[0130] Further, the light emitting area of ​​the sub-pixel 111 surrounding the third sub-pixel 1113 is constructed as an axisymmetric pattern about the second center line 122. In one example, the first direction X and the second direction Y are perpendicular.

[0131] In this way, it is equivalent to making the center of the first sub-pixel 1111 coincide with the center of the third sub-pixel 1113 it surrounds, and making the center of the second sub-pixel 1112 coincide with the center of the third sub-pixel 1113 it surrounds, so that the display distortion caused by the misalignment of the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 1113 can be avoided, thereby improving the display effect. In addition, by setting the first sub-pixel 1111 and the second sub-pixel 1112 as an axisymmetric pattern, the first sub-pixel 1111 and the second sub-pixel 1112 can be arranged more compactly and evenly, thereby improving the display effect.

[0132] In one embodiment, referring to Figure 3 and Figure 4 As shown, the adjacent sides of the first sub-pixel 1111 and the second sub-pixel 1112 are straight sides and parallel to each other.

[0133] In this way, the distance between the adjacent first sub-pixel 1111 and the second sub-pixel 1112 can be made close enough, thereby increasing the aperture ratio and further improving the display effect.

[0134] In one embodiment, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the outer contour shape of the first sub-pixel 1111 and the outer contour shape of the second sub-pixel 1112 are polygonal, circular or triangular. It is understandable that the outer contour shape of the first sub-pixel 1111 and the outer contour shape of the second sub-pixel 1112 can also be a fan-shaped or irregular shape. The embodiment of the present application does not limit the outer contour shape of the first sub-pixel 1111 and the outer contour shape of the second sub-pixel 1112.

[0135] In one embodiment, the outer contour of the first sub-pixel 1111 and the outer contour of the second sub-pixel 1112 are regular quadrilaterals. In this way, the distance between the adjacent first sub-pixel 1111 and the second sub-pixel 1112 can be sufficiently close, thereby improving the aperture ratio and further improving the display effect.

[0136] In one embodiment, the inner contour of the first sub-pixel 1111 is the same as the shape of the third sub-pixel 1113 surrounded by the first sub-pixel 1111. The inner contour of the second sub-pixel 1112 is the same as the shape of the third sub-pixel 1113 surrounded by the second sub-pixel 1112.

[0137] It should be noted that "same shape" only means the same shape, not the same size. Exemplarily, if the inner contour of the first sub-pixel 1111 is an equilateral triangle, then the shape of the third sub-pixel 1113 surrounded by the first sub-pixel 1111 is also an equilateral triangle.

[0138] The above setting can make the third sub-pixel 1113 adapt to the shape of the first sub-pixel 1111 or the second sub-pixel 1112 around it, so that the space between the third sub-pixel 1113 and the first sub-pixel 1111 or the second sub-pixel 1112 around it is smaller, thereby increasing the aperture ratio and further improving the display effect.

[0139] In one embodiment, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the shape of the third sub-pixel 1113 is a polygon or a circle, and the number of sides of the polygon is greater than or equal to 4. In one example, the shape of the third sub-pixel 1113 can be a regular polygon.

[0140] In one embodiment, the third sub-pixel 1113 is in the shape of a regular quadrilateral, so that the shape of the third sub-pixel 1113 is relatively regular, which is beneficial to improve the aperture ratio and thus improve the display effect.

[0141] In one embodiment, the pixel arrangement structure 100 includes a plurality of pixel groups 110 that are repeatedly arranged. The plurality of pixel groups 110 are arranged in rows along a first direction X and in columns along a second direction Y that intersects the first direction X. Each pixel group 110 includes two first sub-pixels 1111, two second sub-pixels 1112, and four third sub-pixels 1113. In the same pixel group 110, each first sub-pixel 1111 is adjacent to two second sub-pixels 1112. Each second sub-pixel 1112 is adjacent to two first sub-pixels 1111. In one embodiment, the first direction X is perpendicular to the second direction Y.

[0142] In this way, on the one hand, the number of third sub-pixels 1113 can be equal to the resolution, thereby improving the display effect; on the other hand, the arrangement of sub-pixels 111 inside the pixel group 110 can be made more regular, which is conducive to improving the aperture ratio and thus improving the display effect.

[0143] In one embodiment, in any two adjacent pixel groups 110, a first sub-pixel 1111 in one pixel group 110 is adjacent to a second sub-pixel 1112 in another pixel group 110, and a second sub-pixel 1112 in one pixel group 110 is adjacent to a first sub-pixel 1111 in another pixel group 110.

[0144] In this way, it is equivalent to arranging the first sub-pixels 1111 and the second sub-pixels 1112 alternately along the row direction or the column direction, thereby avoiding the color edge problem formed when the first sub-pixel 1111 and the second sub-pixel 1112 are located in the same row or the same column.

[0145] In one embodiment, in the same pixel group 110, the center line connecting all the third sub-pixels 1113 forms a quadrilateral. Exemplarily, the quadrilateral may be a rectangle, a parallelogram, or a trapezoid.

[0146] In one embodiment, referring to Figure 3 As shown, in the same pixel group 110, the center line of all third sub-pixels 1113 is a regular quadrilateral. In this way, all sub-pixels 111 are not misaligned in the first direction X and the second direction Y, which improves the problem of distortion in the first direction X and the second direction Y.

[0147] In another example, referring to Figure 7As shown, the shape of the third sub-pixel 1113 is different from the outer contour shape of the first sub-pixel 1111 or the second sub-pixel 1112 in its periphery. For example, the shape of the third sub-pixel 1113 is a triangle, and the outer contour shape of the first sub-pixel 1111 or the second sub-pixel 1112 in its periphery is a circle. Alternatively, the shape of the third sub-pixel 1113 is a circle, and the outer contour shape of the first sub-pixel 1111 or the second sub-pixel 1112 in its periphery is a square or a triangle. The shapes of the first sub-pixel 1111, the second sub-pixel 1112, and the third sub-pixel 1113 are not limited in the embodiment of the present application.

[0148] In one embodiment, in the same pixel group 110 , two first sub-pixels 1111 are respectively located on two sides of the first extension line 123 , and the first extension line 123 passes through two second sub-pixels 1112 .

[0149] In one embodiment, in the same pixel group 110, two first sub-pixels 1111 are symmetrically arranged about the first extension line 123. In this way, the first sub-pixels 1111 can be arranged more compactly and evenly, thereby improving the display effect.

[0150] In one embodiment, the first extension line 123 intersects both the first direction X and the second direction Y.

[0151] In one embodiment, the angle α between the first extension line 123 and the first direction X satisfies the condition: 30°≤α≤60°. In a preferred embodiment, the angle α between the first extension line 123 and the first direction X is 45°, which is equivalent to symmetrically arranging the two first sub-pixels 1111 along the diagonal of the virtual square where the pixel group 110 is located. In this way, the first sub-pixels 1111 can be arranged more compactly and evenly, thereby improving the display effect.

[0152] In one embodiment, the angle β between the first extension line 123 and the second direction Y satisfies the condition: 30°≤β≤60°. In a preferred embodiment, the angle β between the first extension line 123 and the second direction Y is 45°, which is equivalent to symmetrically arranging the two first sub-pixels 1111 along the diagonal of the virtual square where the pixel group 110 is located. In this way, the first sub-pixels 1111 can be arranged more compactly and evenly, thereby improving the display effect.

[0153] In one embodiment, in the same pixel group 110 , the first extension line 123 passes through the centers of two second sub-pixels 1112 .

[0154] In one embodiment, in the same pixel group 110, each second sub-pixel 1112 is symmetrically arranged about the first extension line 123. In this way, the second sub-pixels 1112 can be arranged more compactly and evenly, thereby improving the display effect.

[0155] In one embodiment, in the same pixel group 110 , the first extension line 123 also passes through two third sub-pixels 1113 respectively surrounded by two second sub-pixels 1112 .

[0156] In one embodiment, in the same pixel group 110 , the first extension line 123 also passes through the centers of two third sub-pixels 1113 respectively surrounded by the two second sub-pixels 1112 .

[0157] In one embodiment, in the same pixel group 110 , each of the two third sub-pixels 1113 passed by the first extension line 123 is symmetrically arranged with respect to the first extension line 123 .

[0158] In this way, on the one hand, the sub-pixels 111 in the same pixel group 110 can be arranged more compactly and evenly, thereby improving the display effect. On the other hand, it is beneficial for the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 1113 to focus light, thereby improving the display effect.

[0159] In one embodiment, in the same pixel group 110 , two second sub-pixels 1112 are respectively located on two sides of the second extension line 124 , and the second extension line 124 passes through two first sub-pixels 1111 .

[0160] In one embodiment, in the same pixel group 110, two second sub-pixels 1112 are symmetrically arranged about the second extension line 124. In this way, the second sub-pixels 1112 can be arranged more compactly and evenly, thereby improving the display effect.

[0161] In one embodiment, the second extension line 124 intersects both the first direction X and the second direction Y.

[0162] In one embodiment, the angle γ between the second extension line 124 and the first direction X satisfies the condition: 30°≤γ≤60°. In a preferred embodiment, the angle γ between the second extension line 124 and the first direction X is 45°, which is equivalent to symmetrically arranging the two second sub-pixels 1112 along the diagonal of the virtual square where the pixel group 110 is located. In this way, the second sub-pixels 1112 can be arranged more compactly and evenly, thereby improving the display effect.

[0163] In one embodiment, the angle θ between the second extension line 124 and the second direction Y satisfies the condition: 30°≤θ≤60°. In a preferred embodiment, the angle θ between the second extension line 124 and the second direction Y is 45°, which is equivalent to symmetrically arranging the two second sub-pixels 1112 along the diagonal of the virtual square where the pixel group 110 is located. In this way, the second sub-pixels 1112 can be arranged more compactly and evenly, thereby improving the display effect.

[0164] In one embodiment, in the same pixel group 110 , the second extension line 124 passes through the centers of two first sub-pixels 1111 .

[0165] In one embodiment, in the same pixel group 110, each first sub-pixel 1111 is symmetrically arranged about the second extension line 124. In this way, the second sub-pixels 1112 can be arranged more compactly and evenly, thereby improving the display effect.

[0166] In one embodiment, in the same pixel group 110 , the second extension line 124 further passes through two third sub-pixels 1113 respectively surrounded by the two first sub-pixels 1111 .

[0167] In one embodiment, in the same pixel group 110 , the second extension line 124 also passes through the centers of two third sub-pixels 1113 respectively surrounded by the two first sub-pixels 1111 .

[0168] In one embodiment, each of the two third sub-pixels 1113 passed by the second extension line 124 is symmetrically disposed with respect to the second extension line 124 .

[0169] In this way, on the one hand, the sub-pixels 111 in the same pixel group 110 can be arranged more compactly and evenly, thereby improving the display effect. On the other hand, it is beneficial for the first sub-pixel 1111, the second sub-pixel 1112 and the third sub-pixel 1113 to focus light, thereby improving the display effect.

[0170] Second, refer to Figure 8 As shown, an embodiment of the present application provides a display panel 10, which may be an OLED (Organic Light-Emitting Diode) display panel. The display panel 10 includes a pixel arrangement structure 100 as in any embodiment of the first aspect.

[0171] Specifically, the display panel 10 further includes a substrate 200 and an isolation structure 300. Exemplarily, the substrate 200 may be an array substrate. A plurality of first sub-pixels 1111, a plurality of second sub-pixels 1112, and a plurality of third sub-pixels 1113 are disposed on the substrate 200. The isolation structure 300 is located between at least some adjacent sub-pixels 111.

[0172] The light emitting area of ​​the first sub-pixel 1111 encloses a first accommodating area, and the corresponding third sub-pixel 1113 is located in the first accommodating area. The light emitting area of ​​the second sub-pixel 1112 encloses a second accommodating area, and the corresponding third sub-pixel 1113 is located in the second accommodating area.

[0173] The display panel provided in the embodiment of the present application makes the light-emitting area of ​​at least part of the first sub-pixel 1111 surround at least part of the light-emitting area of ​​the third sub-pixel 1113 in one-to-one correspondence, and makes the light-emitting area of ​​at least part of the second sub-pixel 1112 surround at least part of the light-emitting area of ​​the third sub-pixel 1113 in one-to-one correspondence. In this way, the space around the third sub-pixel 1113 can be fully utilized, which is conducive to improving the aperture ratio and further improving the display effect.

[0174] In one embodiment, the light-emitting area of ​​the first sub-pixel 1111 encloses a first closed accommodating area. The light-emitting area of ​​the second sub-pixel 1112 encloses a second closed accommodating area. In this way, the light-emitting area of ​​the sub-pixel 111 (the first sub-pixel 1111 or the second sub-pixel 1112) corresponding to each third sub-pixel 1113 surrounds the periphery of the entire light-emitting area of ​​the third sub-pixel 1113.

[0175] In this way, on the one hand, the light-emitting area of ​​the first sub-pixel 1111 and the second sub-pixel 1112 can be made larger, which is beneficial to improving the aperture ratio and thus improving the display effect. On the other hand, the first sub-pixel 1111 and the second sub-pixel 1112 are arranged between any two adjacent third sub-pixels 1113, and the distance between adjacent third sub-pixels 1113 can be appropriately increased, which can not only avoid the display graininess caused by the human eye's inability to distinguish the sensitive sub-pixels 111 and identifying them as one during display, but also help reduce the risk of color mixing and color deviation, and improve color fringing.

[0176] In one embodiment, the orthographic projection area of ​​the light emitting region of the first sub-pixel 1111 on the substrate 200 is not equal to the orthographic projection area of ​​the light emitting region of the second sub-pixel 1112 on the substrate 200 .

[0177] In this way, the size of the light-emitting area of ​​the sub-pixel 111 can be set according to the lifespan of the light-emitting materials of different types of sub-pixels 111, which is beneficial to improving the display effect.

[0178] In one embodiment, the orthographic projection area of ​​the light emitting area of ​​the first sub-pixel 1111 on the substrate 200 is larger than the orthographic projection area of ​​the light emitting area of ​​the second sub-pixel 1112 on the substrate 200. This is beneficial to increase the life of the first sub-pixel 1111, thereby improving the display effect.

[0179] In one embodiment, the sub-pixel 111 includes a first electrode 111a, a light-emitting functional layer 111b, and a second electrode 111c stacked on the substrate 200 in a direction away from the substrate 200. The second electrode 111c of the sub-pixel 111 is electrically connected to the isolation structure 300. It is understood that the isolation structure 300 may include a conductive material so that the isolation structure 300 can also be used to transmit electrical signals.

[0180] In one embodiment, a pixel defining layer 400 is disposed on the substrate 200 , and the pixel defining layer 400 defines a plurality of pixel openings, and the sub-pixels 111 are disposed in the pixel openings.

[0181] In one embodiment, the isolation structure 300 includes a first isolation portion 300a and a second isolation portion 300b stacked on the substrate 200, and the outer contour of the orthographic projection of the second isolation portion 300b on the substrate 200 is located outside the outer contour of the orthographic projection of the first isolation portion 300a on the substrate 200. The first isolation portion 300a includes a conductive material, and the second electrode 111c of the sub-pixel 111 is electrically connected to the first isolation portion 300a, so that the second electrode 111c is electrically conductive to the first isolation portion 300a.

[0182] In this way, the isolation structure 300 can form an undercut structure with a "large top and small bottom", and when the sub-pixel 111 is evaporated, the undercut structure can isolate the light-emitting material of the sub-pixel 111. By making the first isolation portion 300a include a conductive material, it is convenient to electrically connect the second electrode 111c to the first isolation portion 300a of the isolation structure 300, so that the second electrode 111c of the sub-pixel 111 is connected to the driving circuit through the first isolation portion 300a, so that the wiring arrangement of the display area is more optimized.

[0183] In one embodiment, the material of the first isolation portion 300 a includes at least one of metal and metal oxide.

[0184] Illustratively, the metal may be silver, copper, titanium, aluminum, etc. The metal oxide may be tin oxide, zinc oxide, cadmium oxide, indium oxide, indium tin oxide, zinc indium oxide, zinc gallium oxide, zinc aluminum oxide, titanium tantalum oxide, etc.

[0185] In one embodiment, the light-emitting functional layer 111b includes at least a light-emitting layer (Emission layer, EML), and may also include one or more of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole blocking layer (HBL) and an electron blocking layer (EBL). Alternatively, the light-emitting functional layer 111b may also be a stacked light-emitting structure, that is, including at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.

[0186] Thirdly, refer to Figure 8 and Fig. 9 As shown, the embodiment of the present application further provides a display panel 10 , which includes a substrate 200 and an isolation structure 300 , wherein the isolation structure 300 includes a first isolation structure 310 and a plurality of second isolation structures 320 .

[0187] Specifically, the first isolation structure 310 has a plurality of first openings 310a and a plurality of second openings 310b arranged at intervals. The plurality of first openings 310a and the plurality of second openings 310b are alternately arranged in rows along a first direction X and alternately arranged in columns along a second direction Y perpendicular to the first direction X.

[0188] Specifically, a plurality of second isolation structures 320 are arranged in a one-to-one correspondence in intervals in the first opening 310a and the second opening 310b. Each second isolation structure 320 encloses a third accommodating area 530. The second isolation structures 320 in the first opening 310a and the first isolation structures 310 outside the second isolation structures 320 together enclose the first accommodating area 510. The second isolation structures 320 in the second opening 310b and the first isolation structures 310 outside the second isolation structures 320 together enclose the second accommodating area 520.

[0189] A plurality of sub-pixels 111 are disposed at intervals on the substrate 200. The plurality of sub-pixels 111 include a plurality of first sub-pixels 1111, a plurality of second sub-pixels 1112, and a plurality of third sub-pixels 1113. The first sub-pixels 1111 are located in the first accommodating area 510, the second sub-pixels 1112 are located in the second accommodating area 520, and the third sub-pixels 1113 are located in the third accommodating area 530.

[0190] The above arrangement facilitates the sub-pixels 111 to form a specific arrangement structure on the substrate 200, that is, in each row and each column, the first sub-pixels 1111 and the second sub-pixels 1112 are arranged alternately, the first sub-pixels 1111 and the second sub-pixels 1111 are both ring-shaped, and the third sub-pixel 1113 is arranged inside each of the first sub-pixel 1111 and the second sub-pixel 1112. In this way, the space outside the third sub-pixel 1113 can be fully utilized, which is conducive to improving the aperture ratio and further improving the display effect.

[0191] In one embodiment, along the first direction X, the size of the first opening 310a is greater than the size of the second opening 310b. And / or, along the second direction Y, the size of the first opening 310a is greater than the size of the second opening 310b. Specifically, the size of the first opening 310a along the first direction X is W1, and the size of the second opening 310b along the first direction X is W2, W1>W2. The size of the first opening 310a along the second direction Y is L1, and the size of the second opening 310b along the second direction Y is L2, L1>L2.

[0192] It should be noted that the first isolation structure 310 is a grid-like structure. Further, in the first isolation structure 310 , the multiple strip portions extending along the first direction X are in a zigzag shape, and the multiple strip portions extending along the second direction Y are also in a zigzag shape.

[0193] In one embodiment, the sub-pixel 111 includes a first electrode 111a, a light-emitting functional layer 111b, and a second electrode 111c stacked on the substrate 200 in a direction away from the substrate 200. The second electrode 111c of the sub-pixel 111 is electrically connected to the isolation structure 300. It is understood that the isolation structure 300 may include a conductive material so that the isolation structure 300 can also be used to transmit electrical signals.

[0194] In one embodiment, a pixel defining layer 400 is disposed on the substrate 200 , and the pixel defining layer 400 defines a plurality of pixel openings, and the sub-pixels 111 are disposed in the pixel openings.

[0195] In one embodiment, the isolation structure 300 includes a first isolation portion 300a and a second isolation portion 300b stacked on the substrate 200, and the outer contour of the orthographic projection of the second isolation portion 300b on the substrate 200 is located outside the outer contour of the orthographic projection of the first isolation portion 300a on the substrate 200.

Alternatively, the light-emitting functional layer 111b may also be a stacked light-emitting structure, that is, including at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.

[0200] The display panel 10 in at least one embodiment of the present application includes a display area and a non-display area, and the display area displays an image by arranging a plurality of sub-pixels 111 in the display area. Specifically, the display area can be a rectangle, and the non-display area is arranged around the display area. Of course, the shape and arrangement of the display area and the non-display area include but are not limited to the above examples. For example, when the display panel 10 is used for a wearable device worn on a user, the display area can have a circular shape like a watch. When the display panel 10 is used for display on a vehicle, the display area and the non-display area can adopt, for example, a circular, polygonal or other shape. The display area is provided with a plurality of sub-pixels 111 that emit light of different colors, and the sub-pixel 111 is characterized as the smallest unit for emitting light (for example, the smallest addressable unit of the display panel).

[0201] It can be understood that the display panel 10 provided in the present application can be applied to a display device, which can be a laptop computer, a mobile phone, a wireless device, a personal digital assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a camcorder, a game console, a watch, a clock, a calculator, a television monitor, a flat-panel display, a computer monitor, a car display (for example, an odometer display, etc.), a navigator, a cockpit controller and / or display, a display of a camera view (for example, a display of a rearview camera in a vehicle), an electronic photo, an electronic billboard or sign, a projector, etc.
