[0070] FIG. 1 is a plan view of a display panel 10 according to some embodiments of the present disclosure. For the sake of clarity, only some of the sub-pixels P are shown in FIG. 1, and the number of sub-pixels P included in the actual display panel 10 is not limited to that shown in FIG. 1.

[0071] In some embodiments, as shown in FIG. 1, the display panel 10 includes a plurality of sub-pixels P. In a front projection onto a display surface of the display panel 10, each of the sub-pixels P includes a first boundary V1 and a second boundary V2 surrounding the first boundary V1.

[0072] FIG. 2 is a sectional view of the display panel 10 taken along the section line A-A in FIG. 1. For the purpose of clearly showing and explaining the first boundary V1 and the second boundary V2 of the sub-pixel P, only part of the light-emitting device 1 and the pixel circuit 2 are shown in FIG. 2. The light-emitting device 1 and the pixel circuit 2 of the actual display panel 10 further include other structures which are not shown in FIG. 2.

[0073] In some embodiments, as shown in FIG. 2, the display panel 10 includes a substrate 3, and the light-emitting device 1 and the pixel circuit 2 disposed on the substrate 3. The pixel circuit 2 is electrically connected to the light-emitting device 1. The pixel circuit 2 is configured to provide a driving signal for the light-emitting device 1 connected thereto.

[0074] The light-emitting device 1 includes, but is not limited to, an OLED (Organic Light-Emitting Diode) light-emitting device or an MLED (Mini Light Emitting Diode; or, Micro Light Emitting Diode) light-emitting device. In the following, some embodiments of the present disclosure are exemplarily described by taking the light-emitting device 1 as an OLED light-emitting device.

[0075] In the case where the light-emitting device 1 is an OLED light-emitting device, as shown in FIG. 2, the light-emitting device 1 includes a first electrode 11, a light-emitting part 12, and a second electrode 13 which are sequentially disposed in the thickness direction (for example, the Z direction shown in FIG. 2) of the OLED light-emitting device. The display panel 10 further includes a pixel definition layer PDL which includes a plurality of openings K. Each light-emitting device 1 is disposed in one opening K of the pixel definition layer PDL.

[0076] Exemplarily, the preparation process of the display panel 10 includes at least steps S1-S5.

[0077] S1, forming a plurality of pixel circuits 2 on the substrate 3.

[0078] S2, forming a plurality of first electrodes 11 on the side of the pixel circuit 2 away from the substrate 3.

[0079] As shown in FIG. 2, the plurality of first electrodes 11 are spaced apart from each other. Each first electrode 11 is electrically connected to one pixel circuit 2.

[0080] S3, forming a pixel definition layer PDL on the side of the plurality of first electrodes 11 away from the substrate 3. The pixel definition layer PDL includes a plurality of openings K.

[0081] As shown in FIG. 2, each opening K of the pixel definition layer PDL exposes at least part of one first electrode 11.

[0082] S4. Forming a plurality of light emitting portions 12 on a side of the pixel definition layer PDL away from the substrate 3.

[0083] As shown in FIG. 2, at least part of each light emitting portion 12 is located within an opening K and contacts a first electrode 11. The plurality of light emitting portions 12 are spaced apart from each other.

[0084] S5. Forming a plurality of second electrodes 13 on a side of the plurality of light emitting portions 12 away from the substrate 3.

[0085] As shown in FIG. 2, the plurality of second electrodes 13 can be connected to each other to form an electrode layer, and a portion of the electrode layer corresponding to each light emitting portion 12 serves as a second electrode 13. In a thickness direction of the OLED light emitting device (for example, the Z direction shown in FIG. 2), the first electrode 11, the light emitting portion 12, and the portion of the second electrode 13 within the opening K of the pixel definition layer PDL overlap each other.

[0086] As shown in FIGS. 1 and 2, each sub-pixel P includes a light emitting device 1 and a pixel circuit 2 arranged corresponding to the light emitting device 1, and a first boundary V1 of the sub-pixel P can refer to a boundary of the first electrode 11 of the OLED light emitting device, and a second boundary V2 of the sub-pixel P can refer to a boundary of the opening K of the pixel definition layer PDL. The second boundaries V2 of any two adjacent sub-pixels P have a spacing therebetween.

[0087] In some embodiments, as shown in FIGS. 1 and 3, the plurality of sub-pixels P in the display panel 10 include a plurality of first color sub-pixels P1, and the plurality of first color sub-pixels P1 are arranged at equal intervals.

[0088] For example, as shown in FIGS. 1 and 3, the display panel 10 includes a plurality of first sub-pixel columns L1 arranged at intervals along a first direction X, and each first sub-pixel column L1 includes a plurality of first color sub-pixels P1 arranged at intervals along a second direction Y. The first direction X and the second direction Y intersect each other.

[0089] In the two adjacent first sub-pixel columns L1, each first color sub-pixel P1 in one of the first sub-pixel columns L1 corresponds to a gap region between two adjacent first color sub-pixels P1 in the other of the first sub-pixel columns L1 in the first direction X.

[0090] The interval between the first color sub-pixels P1 refers to an interval between one first color sub-pixel P1 in one of the first sub-pixel columns L1 and two adjacent first color sub-pixels P1 in the other of the first sub-pixel columns L1 in the first direction X, for example, the intervals d1 and d3 and the intervals d2 and d4 shown in FIG. 3, and d1 = d2 = d3 = d4.

[0091] Based on the arrangement of the first color sub-pixels P1 in the display panel 10 in the arrangement shown in FIG. 2, the arrangement of all the sub-pixels P of the display panel 10 in the present disclosure will be described exemplarily below.

[0092] FIG. 4 is a partially enlarged structural view of the display panel 10 shown in FIG. 1.

[0093] In some embodiments, as shown in FIGS. 1 and 4, the plurality of sub-pixels P in the display panel 10 further include a plurality of second color sub-pixels P2 and a plurality of third color sub-pixels P3, each first color sub-pixel P1 is surrounded by the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3, and the line connecting the geometric centers of the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 forms a polygon.

[0094] The arrangement of the sub-pixels P in the display panel 10 has certain influence on the display effect and screen performance of the display panel 10. As shown in FIG. 4, each first color sub-pixel P1, and the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 can be arranged in a shape similar to a honeycomb.

[0095] Taking each first color sub-pixel P1, and the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 as a pixel group, as shown in FIG. 4, the adjacent pixel groups in the display panel 10 share part of the second color sub-pixels P2 and / or the third color sub-pixels P3.

[0096] By multiplexing part of the sub-pixels P (the second color sub-pixels P2 and / or the third color sub-pixels P3) between the adjacent pixel groups, when the display panel 10 displays an image, smoother color transition between the adjacent pixel groups can be achieved, color discontinuity phenomenon is reduced, the display image of the display panel 10 is more delicate, and the picture display granularity is lower.

[0097] At the same time, multiplexing part of the sub-pixels P between the adjacent pixel groups can not only ensure the display effect, but also reduce the number of sub-pixels P, thereby reducing the overall energy consumption of the screen. In the preparation process of the display panel 10, since the number of sub-pixels P is reduced, the risk of display abnormality of the display panel 10 caused by defects of individual sub-pixels P (for example, problems such as luminance reduction or color deviation of the sub-pixels P) is also reduced, and the yield is improved.

[0098] Based on this, in some embodiments, as shown in FIG. 1, the first color sub-pixel P1 is a blue sub-pixel, one of the second color sub-pixel P2 and the third color sub-pixel P3 is a red sub-pixel, and the other is a green sub-pixel. In this way, as shown in FIGS. 4 and 5, in the display panel 10, each blue sub-pixel is surrounded by multiple red sub-pixels and multiple green sub-pixels, and the line connecting the geometric centers of the multiple red sub-pixels and the multiple green sub-pixels surrounding the blue sub-pixel is a polygon.

[0099] In the case where the light-emitting device is an OLED light-emitting device, the service life of the blue OLED light-emitting device is shorter than that of the red OLED light-emitting device and the green OLED light-emitting device, so in the display panel 10, the service life of the blue sub-pixel is shorter than that of the red sub-pixel and the green sub-pixel.

[0100] In some embodiments of the present disclosure, the design of surrounding the blue sub-pixel with multiple red sub-pixels and multiple green sub-pixels is adopted in each pixel group, and part of the red sub-pixels and the green sub-pixels are shared between adjacent pixel groups, so that the number of red sub-pixels and green sub-pixels in the display panel 10 is greater than the number of blue sub-pixels. By reducing the number of blue sub-pixels, the luminous intensity of the blue sub-pixel can be reduced, thereby slowing down the decay rate of the blue sub-pixel, balancing the service life of the sub-pixels P of different light-emitting colors in the display panel 10, and thereby prolonging the service life of the display panel 10. At the same time, since the luminous efficiency of the blue sub-pixel is lower than that of the red sub-pixel and the green sub-pixel, reducing the number of blue sub-pixels can reduce unnecessary energy consumption and improve the energy efficiency ratio of the display panel 10.

[0101] In some embodiments, as shown in FIG. 1, the first sub-pixel column L1 includes multiple first color sub-pixels P1 and multiple second color sub-pixels P2, and two second color sub-pixels P2 are arranged between every two adjacent first color sub-pixels P1 in the first sub-pixel column L1.

[0102] By arranging two second color sub-pixels P2 between every two adjacent first color sub-pixels P1 in the first sub-pixel column L1, the two adjacent second color sub-pixels P2 can ensure that the display panel 10 displays color more uniformly and accurately when displaying the second color or a color containing the second color. At the same time, the two adjacent second color sub-pixels P2 can work together and can be independently adjusted in brightness and color as needed to adapt to different display requirements, so that the details in the image displayed by the display panel 10 are clearer and more discernible, the picture displayed by the display panel 10 can show more details and levels of sense, improve the detail performance of the display panel 10, and help to improve the resolution and clarity of the display panel 10.

[0103] When the second color sub-pixel P2 is a green sub-pixel, the green sub-pixel has a higher luminance in the visible spectrum, and thus two adjacent green sub-pixels can enhance the luminance of the display panel 10 to display a brighter and clearer image. When the display panel 10 displays a dark or light image, the adjacent green sub-pixels help to optimize the contrast, so that the image is more vivid and stereoscopic.

[0104] Based on this, in some embodiments, as shown in FIG. 1, the display panel 10 further includes a plurality of second sub-pixel columns L2, and the second sub-pixel columns L2 include a plurality of third color sub-pixels P3. The first sub-pixel columns L1 and the second sub-pixel columns L2 are alternately arranged along the second direction Y.

[0105] For example, as shown in FIG. 4, in two adjacent first sub-pixel column L1 and second sub-pixel column L2, each first color sub-pixel P1 in the first sub-pixel column L1 corresponds to a gap region between two adjacent third color sub-pixels P3 in the second sub-pixel column L2 in the first direction X.

[0106] As shown in FIG. 4, in three adjacent first sub-pixel column L1 and two second sub-pixel column L2 interlaced in the three first sub-pixel column L1, the first color sub-pixel P1 in the middle first sub-pixel column L1 is surrounded by a plurality of second color sub-pixels P2 and second color sub-pixels P3 in the first sub-pixel column L1 and the second sub-pixel column L2 on both sides.

[0107] In some embodiments, as shown in FIG. 4, two first sub-pixel columns L1 located on both sides of the second sub-pixel column L2 and adjacent to the second sub-pixel column L2 are a first target sub-pixel column L11 and a second target sub-pixel column L12, respectively. In the second sub-pixel column L2, the geometric center of each third color sub-pixel P3 is located at the midpoint of the line connecting the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the first target sub-pixel column L11 and the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the second target sub-pixel column L12.

[0108] As shown in FIG. 4, in the second sub-pixel column L2, the distance between the geometric center of each third color sub-pixel P3 and the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the first target sub-pixel column L11 is t1; the distance between the geometric center of the third color sub-pixel P3 and the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the second target sub-pixel column L12 is t2; t1=t2.

[0109] Thus, in the display panel 10, the geometric centers of any two adjacent sub-pixels P among the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 are the same or substantially the same, and the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 are uniformly distributed, which is beneficial to improve the uniformity of the pixel density of the display panel 10, so that the image details can be fully displayed, and thus the image displayed by the display panel 10 visually presents higher resolution and clearer image.

[0110] FIG. 5 is an enlarged structural view of one pixel group in the display panel 10 shown in FIG. 1, each pixel group including one first color sub-pixel P1, and a plurality of second color sub-pixels P2 and a plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1.

[0111] In some embodiments, as shown in FIG. 5, the total number of the second color sub-pixels P2 and the third color sub-pixels P3 surrounding the first color sub-pixel P1 is 10, and the geometric centers of the 10 sub-pixels P are connected in a hexagon, which is an axisymmetric figure. The axisymmetric figure is symmetric with respect to a first symmetry axis D1 and a second symmetry axis D2, the first symmetry axis D1 is parallel to a first direction X, and the second symmetry axis D2 is parallel to a second direction Y. The first direction X is the column direction of the arrangement of the plurality of sub-pixels, and the second direction Y intersects the first direction X.

[0112] For example, as shown in FIG. 5, the 10 sub-pixels P surrounding the first color sub-pixel P1 include 6 second color sub-pixels P2 and 4 third color sub-pixels P3. The 6 second color sub-pixels P2 and the 4 first color sub-pixels P1 are symmetrically arranged with respect to the first symmetry axis D1 and symmetrically arranged with respect to the second symmetry axis D2.

[0113] In the plurality of sub-pixels P included in the display panel 10, the number ratio of the first color sub-pixels P1, the second color sub-pixels P2 and the third color sub-pixels P3 is 1:2:2.

[0114] In the display panel 10, the number of red sub-pixels and green sub-pixels (second color sub-pixels P2 and third color sub-pixels P3) is greater than the number of blue sub-pixels (first color sub-pixels P1) by adopting such a pixel arrangement manner, and by reducing the number of blue sub-pixels, the luminous intensity of the blue sub-pixels can be reduced, thereby slowing down the decay rate of the blue sub-pixels, balancing the service life of the sub-pixels P of different light colors in the display panel 10, and further prolonging the service life of the display panel 10. At the same time, since the luminous efficiency of the blue sub-pixels is lower than that of the red sub-pixels and the green sub-pixels, reducing the number of blue sub-pixels can reduce unnecessary energy consumption and improve the energy efficiency ratio of the display panel 10.

[0115] In some embodiments of the display panel 10, the distance between any two adjacent sub-pixels P in the first column L1 of sub-pixels can be the same or not exactly the same, and can be designed as needed, and the arrangement is more flexible.

[0116] The distance described herein can refer to the distance between the geometric centers of the sub-pixels P, or the distance between the boundaries of the sub-pixels P. The geometric center of the sub-pixel P is different according to the shape of the sub-pixel P.

[0117] In some examples, the projection shape of the sub-pixel P (for example, the first color sub-pixel P1 shown in FIG. 1) on the display surface of the display panel 10 is a circle, and the geometric center of the sub-pixel P can refer to the center of the projection shape (circle) of the sub-pixel P on the display surface of the display panel 10.

[0118] In other examples, the projection shape of the sub-pixel P (for example, the third color sub-pixel P3 shown in FIG. 1) on the display surface of the display panel 10 is an ellipse, and the geometric center of the sub-pixel P can refer to the intersection of the major axis and the minor axis of the projection shape (ellipse) of the sub-pixel P on the display surface.

[0119] In yet other examples, the projection shape of the sub-pixel P (for example, the first color sub-pixel P1 shown in FIG. 6) on the display surface of the display panel 10 is a hexagon, and the geometric center of the sub-pixel P can refer to the centroid of the projection shape (hexagon) of the sub-pixel P on the display surface.

[0120] In yet other examples, the projection shape of the sub-pixel P (for example, the second color sub-pixel P2 shown in FIG. 6) on the display surface of the display panel 10 is a trapezoid, and the geometric center of the sub-pixel P can refer to the intersection of the diagonals of the projection shape (trapezoid) of the sub-pixel P on the display surface.

[0121] In yet other examples, the projection shape of the sub-pixel P (for example, the third color sub-pixel P3 shown in FIG. 6) on the display surface of the display panel 10 is a rhombus, and the geometric center of the sub-pixel P can refer to the intersection of the diagonals of the projection shape (rhombus) of the sub-pixel P on the display surface.

[0122] The above-mentioned circle can also be a circle that is close to a perfect circle but not a perfect circle, or a polygon that is close to a circle; the above-mentioned ellipse can also be a figure that is similar to a perfect ellipse but has some deviation, or a polygon that is close to an ellipse; among the above-mentioned hexagons, each side of the hexagon can be the same or approximately the same, or not exactly the same; the above-mentioned trapezoid can also be a figure that is close to a trapezoid (for example, the top base and the bottom base are not parallel, but the included angle formed is less than 10°); the above-mentioned rhombus can also be a polygon that is close to a rhombus (for example, the opposite two sides are not parallel, but the included angle formed is less than 10°).

[0123] Based on this, the arrangement of the plurality of first color sub-pixels P1 in the first sub-pixel column L1 is described below.

[0124] In some embodiments, as shown in FIG. 4, the projection shape of the first color sub-pixel P1 on the display surface of the display panel 10 is a circle, the projection shape of one of the second color sub-pixel P2 and the third color sub-pixel P3 on the display surface is a circle, and the projection shape of the other of the second color sub-pixel P2 and the third color sub-pixel P3 on the display surface is an ellipse.

[0125] In this case, in some embodiments, as shown in FIG. 4, within the first sub-pixel column L1, the distance r2 between the geometric centers of two adjacent second color sub-pixels P2 is the same as or approximately the same as the distance r1 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1.

[0126] In this case, the projection shape of the first color sub-pixel P1 and the second color sub-pixel P2 on the display surface of the display panel 10 can be a circle, and in the first sub-pixel column L1, the distance between the geometric centers of any two adjacent sub-pixels P is the same, i.e., r1=r2.

[0127] The outer dimensions of the projection shapes of the first color sub-pixel P1 and the second color sub-pixel P2 on the display surface of the display panel 10 can be the same, or the outer dimensions of the projection shapes of the first color sub-pixel P1 and the second color sub-pixel P2 on the display surface of the display panel 10 can also be different. The outer dimensions referred to here can refer to the diameter of the projection shape (circle) on the display surface of the display panel 10.

[0128] In the case where the outer dimensions of the shapes of the projections of the first color sub-pixels P1 and the second color sub-pixels P2 on the display surface of the display panel 10 are the same, the distance j2 between two adjacent second color sub-pixels P2 in the first sub-pixel column L1 can also be the same or substantially the same as the distance j1 between the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1, i.e., j1 = j2.

[0129] The distance described herein can refer to the distance between the boundaries of two adjacent sub-pixels P along the line connecting the geometric centers of the projections of the two adjacent sub-pixels P on the display surface of the display panel 10.

[0130] In the case where the outer dimensions of the shapes of the projections of the first color sub-pixels P1 and the second color sub-pixels P2 on the display surface of the display panel 10 are different, the distance j2 between two adjacent second color sub-pixels P2 in the first sub-pixel column L1 is different from the distance j1 between the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1, i.e., j1 ≠ j2.

[0131] In the present embodiment, by making the distances between the geometric centers of the sub-pixels P in the first sub-pixel column L1 the same, the sub-pixels P in the first sub-pixel column L1 are uniformly distributed in the arrangement direction of the first sub-pixel column L1, which can avoid color deviation and unnatural color transition when the display panel 10 displays an image, and is helpful to improve the color accuracy and consistency of the image.

[0132] In some embodiments, as shown in FIGS. 4 and 5, the hexagon formed by the line connecting the geometric centers of the second color sub-pixels P2 and the third color sub-pixels P3 surrounding the first color sub-pixel P1 includes four first sides S1 and two second sides S2, the four first sides S1 are arranged opposite to each other in the second direction Y, and the two second sides S2 are arranged opposite to each other in the first direction X. The length of the first side S1 is greater than the length of the second side S2.

[0133] As shown in FIG. 5, the first side S1 and the second side S2 adjacent to the first side S1 form a first included angle a1, and two adjacent first sides S1 form a second included angle a2. According to different specific arrangement manners of the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 and forming a hexagon with the line connecting the geometric centers, the angles of the first included angle a1 and the second included angle a2 of the hexagon are also different.

[0134] The first included angle a1 is in the range of 90°-135°, and the second included angle a2 is in the range of 80°-160°. For example, the first included angle a1 is 90°, 95°, 97°, 100°, 108°, 115°, 117°, 120°, 125°, 130°, or 135°, and the second included angle a2 is 80°, 85°, 90°, 95°, 100°, 105°, 108°, 110°, 115°, 117°, 120°, 123°, 127°, 129°, 135°, 140°, 143°, 145°, 148°, 152°, 155°, 158°, or 160°.

[0135] For example, as shown in FIG. 5, when the plurality of sub-pixels P in the display panel 10 are arranged in the manner shown in FIGS. 1 and 4, the first included angle a1 of the hexagon formed by the connecting line around the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 surrounding the first color sub-pixel P1 can be 108°, and the second included angle a2 can be 143°. Of course, the first included angle a1 and the second included angle a2 can also be other angles, which are only exemplary descriptions of a possible embodiment of the present disclosure and are not limitations of the present disclosure.

[0136] By adjusting the arrangement of the sub-pixels P in the first sub-pixel column L1, the first included angle a1 and the second included angle a2 formed in the hexagon formed by the connecting line around the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 surrounding the first color sub-pixel P1 can be changed within a certain range, thereby improving the arrangement gap of the sub-pixels P in the display panel 10, reducing the granularity of the display image, and improving the display effect.

[0137] FIG. 6 is a plan view of a display panel 10 according to another embodiment of the present disclosure, and FIG. 7 is an enlarged view of a part of the display panel 10 shown in FIG. 6.

[0138] In some embodiments, as shown in FIGS. 6 and 7, in the display panel 10, unlike the display panel 10 shown in FIG. 1, in the first sub-pixel column L1, the distance r4 between the geometric centers of two adjacent second color sub-pixels P2 is less than the distance r3 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1. That is, (r4) < (r3).

[0139] The projection shape of the first color sub-pixel P1 and the second color sub-pixel P2 in the first sub-pixel column L1 on the display surface of the display panel 10 is circular. The outer size of the projection shape of the first color sub-pixel P1 on the display surface can be larger than the outer size of the projection shape of the second color sub-pixel P2 on the display surface.

[0140] The projection shape of the sub-pixel P (any one of the first color sub-pixel P1, the second color sub-pixel P2 and the third color sub-pixel P3) described in the present disclosure can refer to the size of the opening K of the pixel definition layer PDL, and the size of the projection shape of the sub-pixel P can refer to the size of the first boundary V1 of the sub-pixel P.

[0141] In the first sub-pixel column L1, the arrangement of the second color sub-pixel P2 is closer than that of the first color sub-pixel P1, and the close arrangement of the adjacent second color sub-pixels P2 helps to reduce the color difference and the color block phenomenon of the color transition of the second color in the picture displayed by the display panel 10, making the color transition more smooth and natural, and helping to improve the color accuracy and color restoration degree of the second color of the image displayed by the display panel 10.

[0142] In some examples, as shown in FIG. 7, the ratio of the distance r4 between the geometric centers of the two adjacent second color sub-pixels P2 in the first sub-pixel column L1 to the distance r3 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 is greater than one half. That is, (r4) / (r3)>1 / 2.

[0143] For example, as shown in FIG. 7, the ratio of the distance r4 between the geometric centers of the two adjacent second color sub-pixels P2 in the first sub-pixel column L1 to the distance r3 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 is two thirds. That is, (r4) / (r3)=2 / 3.

[0144] The distance r4 between the geometric centers of the two adjacent second color sub-pixels P2 in the first sub-pixel column L1 and the distance r3 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 can be adaptively designed according to actual needs.

[0145] By adjusting the arrangement of each sub-pixel P in the first sub-pixel column L1, the distance r4 between the geometric centers of the two adjacent second color sub-pixels P2 in the first sub-pixel column L1 and the distance r3 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 also change. Specifically, according to different application scenarios of the display panel 10, the distance r4 and the distance r3 can be adaptively designed according to needs, while ensuring the display quality of the display panel 10, the design of the display panel 10 is more flexible, and can adapt to more different application scenarios.

[0146] FIG. 8 is an enlarged structural view of one pixel group in the display panel 10 shown in FIG. 6, each pixel group including one first-color sub-pixel P1, and a plurality of second-color sub-pixels P2 and a plurality of third-color sub-pixels P3 surrounding the first-color sub-pixel P1.

[0147] Exemplarily, in the case where the plurality of sub-pixels P in the display panel 10 adopt the arrangement manner as shown in FIGS. 6 and 7, as shown in FIG. 8, the first included angle a1 of the hexagon formed by the connecting line surrounding the geometric centers of the second-color sub-pixels P2 and the third-color sub-pixels P3 of the first-color sub-pixel P1 can be 117°, and the second included angle a2 can be 127°. Of course, the angles of the first included angle a1 and the second included angle a2 can also be other angles, which are only exemplarily described herein as one possible embodiment of the present disclosure, and not as a limitation of the present disclosure.

[0148] By adjusting the arrangement manner of each sub-pixel P in the first sub-pixel column L1, the angles of the first included angle a1 and the second included angle a2 formed in the hexagon surrounded by the connecting line surrounding the geometric centers of the second-color sub-pixels P2 and the third-color sub-pixels P3 of the first-color sub-pixel P1 can be changed within a certain range, so as to improve the arrangement gap of the sub-pixels P in the display panel 10, reduce the granularity of the display picture, and improve the display effect.

[0149] FIG. 9 is a plan structural view of a display panel 10 according to another embodiment of the present disclosure, and FIG. 10 is a partial enlarged structural view of the display panel 10 shown in FIG. 9.

[0150] In another embodiment, as shown in FIGS. 9 and 10, in the display panel 10, different from the display panel 10 shown in FIG. 1, the projection shape of the first-color sub-pixel P1 on the display surface of the display panel 10 is a hexagon, the projection shape of one of the second-color sub-pixel P2 and the third-color sub-pixel P3 on the display surface is a trapezoid, and the projection shape of the other of the second-color sub-pixel P2 and the third-color sub-pixel P3 on the display surface is a rhombus.

[0151] Exemplarily, as shown in FIG. 10, in the first sub-pixel column L1, the minimum distance j4 between two adjacent second-color sub-pixels P2 is the same as or substantially the same as the minimum distance j3 between the first-color sub-pixel P1 and the second-color sub-pixel P2 adjacent to the first-color sub-pixel P1. The distance described herein can refer to the distance between the boundaries of the orthographic projection of the sub-pixel P on the display surface of the display panel 10.

[0152] As shown in FIG. 10, in the first sub-pixel column L1, when the opposite boundaries of two adjacent second color sub-pixels P2 form an included angle, the distance between the two adjacent second color sub-pixels P2 has multiple values; when the opposite boundaries of two adjacent second color sub-pixels P2 are parallel to each other, the distance between the two adjacent second color sub-pixels P2 is unique.

[0153] For example, as shown in FIG. 10, in the first sub-pixel column L1, when the opposite boundaries of two adjacent second color sub-pixels P2 are parallel or approximately parallel, the distance between any two adjacent sub-pixels P in the first sub-pixel column L1 is the same, i.e., j3=j4.

[0154] In this way, the distances between the sub-pixels P in the first sub-pixel column L1 are equal, and the sub-pixels P in the first sub-pixel column L1 are uniformly distributed in the arrangement direction of the first sub-pixel column L1. When the display panel 10 displays an image, the color deviation and unnatural color transition can be avoided, which helps to improve the color accuracy and consistency of the image. At the same time, the equal-distance arrangement of the sub-pixels P helps to maintain the uniformity of the pixel density. Each sub-pixel P in the first sub-pixel column L1 is distributed at the same density, so that the image details can be fully displayed, thereby making the image displayed by the display panel 10 visually present higher resolution and clearer image.

[0155] For example, as shown in FIG. 10, the minimum distance j5 between the third color sub-pixel P3 and the first color sub-pixel P1 adjacent to the third color sub-pixel P3 is the same as or approximately the same as the minimum distance j6 between the third color sub-pixel P3 and the second color sub-pixel P2 adjacent to the third color sub-pixel P3. That is, j5=j6.

[0156] In this case, as shown in FIG. 10, the projection shape of the first color sub-pixel P1 on the display surface of the display panel 10 can be a hexagon, the projection shape of the second color sub-pixel P2 on the display surface of the display panel 10 can be a trapezoid, and the projection shape of the third color sub-pixel P3 on the display surface of the display panel 10 can be a rhombus. The distance described herein can refer to the distance between the boundaries of the orthographic projection of the sub-pixel P on the display surface of the display panel 10.

[0157] The opposite boundaries of the third color sub-pixel P3 and the first color sub-pixel P1 adjacent to the third color sub-pixel P3 can be parallel or approximately parallel to each other, and the opposite boundaries of the third color sub-pixel P3 and the second color sub-pixel P2 adjacent to the third color sub-pixel P3 can be parallel or approximately parallel to each other.

[0158] In this way, in the display panel 10, the distance between any two adjacent sub-pixels P among the first color sub-pixel P1 and the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 is the same or substantially the same, the distance between any two adjacent sub-pixels P among the plurality of sub-pixels P in the display panel 10 is the same or substantially the same, the sub-pixels P in the display panel 10 are uniformly distributed, the uniformity of the pixel density of the display panel 10 is good, so that the image details can be fully displayed, thereby making the image displayed by the display panel 10 visually present higher resolution and clearer image.

[0159] FIG. 11 is an enlarged structural view of one pixel group in the display panel 10 shown in FIG. 9, each pixel group including one first color sub-pixel P1 and a plurality of second color sub-pixels P2 and a plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1.

[0160] Exemplarily, in the case where the plurality of sub-pixels P in the display panel 10 adopt the arrangement manner as shown in FIGS. 9 and 10, as shown in FIG. 11, the first included angle α1 of the hexagon formed by the connecting line of the geometric centers of the second color sub-pixels P2 and the third color sub-pixels P3 surrounding the first color sub-pixel P1 can be 115°, and the second included angle α2 can be 129°. Of course, the angles of the first included angle α1 and the second included angle α2 can also be other angles, which are only exemplarily described herein as one possible embodiment of the present disclosure, and not as a limitation of the present disclosure.

[0161] By adjusting the arrangement manner of the sub-pixels P in the first sub-pixel column L1, the angles of the first included angle α1 and the second included angle α2 formed in the hexagon surrounded by the connecting line of the geometric centers of the second color sub-pixels P2 and the third color sub-pixels P3 surrounding the first color sub-pixel P1 can be changed within a certain range, thereby improving the arrangement gap of the sub-pixels P in the display panel 10, reducing the granularity of the display picture, and improving the display effect.

[0162] FIG. 12 is a plan structural view of a display panel 10 according to another embodiment of the present disclosure, and FIG. 13 is a partial enlarged structural view of the display panel 10 shown in FIG. 12.

[0163] In some embodiments, as shown in FIGS. 12 and 13, the first sub-pixel column L1 includes a plurality of first color sub-pixels P1, a plurality of second color sub-pixels P2, and a plurality of third color sub-pixels P3. In the first sub-pixel column L1, one second color sub-pixel P2 and one third color sub-pixel P3 are arranged between every two adjacent first color sub-pixels P1, and the first color sub-pixels P1, the second color sub-pixels P2, and the third color sub-pixels P3 are periodically arranged.

[0164] By arranging one second color sub-pixel P2 and one third color sub-pixel P3 between two adjacent first color sub-pixels P1 in the first sub-pixel column L1, the first color sub-pixels P1, the second color sub-pixels P2 and the third color sub-pixels P3 in the first sub-pixel column L1 are periodically arranged. With such a design, when the display panel 10 displays a picture, the color of the picture displayed by the display panel 10 is more uniform and accurate.

[0165] Meanwhile, the first color sub-pixels P1, the second color sub-pixels P2 and the third color sub-pixels P3 in the first sub-pixel column L1 can work together and can be independently adjusted in brightness and color as needed to adapt to different display requirements, so that the details in the image displayed by the display panel 10 are clearer and more discernible, the picture displayed by the display panel 10 can show more details and levels of feeling, and the display panel 10 has better detail performance, which helps to improve the resolution and clarity of the display panel 10.

[0166] In some embodiments, as shown in FIGS. 12 and 13, the display panel 10 further includes a plurality of second sub-pixel columns L2, and each second sub-pixel column L2 includes second color sub-pixels P2 and third color sub-pixels P3 arranged alternately. The first sub-pixel columns L1 and the second sub-pixel columns L2 are arranged alternately along the second direction Y.

[0167] For example, as shown in FIG. 13, in two adjacent first sub-pixel column L1 and second sub-pixel column L2, each first color sub-pixel P1 in the first sub-pixel column L1 corresponds to a gap region between the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the second sub-pixel column L2 in the first direction X.

[0168] As shown in FIG. 13, in three adjacent first sub-pixel columns L1 and two second sub-pixel columns L2 interlaced in the three first sub-pixel columns L1, the first color sub-pixel P1 in the middle first sub-pixel column L1 is surrounded by a plurality of second color sub-pixels P2 and second color sub-pixels P3 in the first sub-pixel columns L1 and the second sub-pixel columns L2 on both sides.

[0169] In some embodiments, as shown in FIG. 13, the total number of the second color sub-pixels P2 and the third color sub-pixels P3 surrounding the first color sub-pixel P1 is 10, and the connecting line of the geometric centers of the 10 sub-pixels P is a hexagon. The hexagon is an axisymmetric figure. The axisymmetric figure is symmetrical with respect to a first symmetry axis D1 and symmetrical with respect to a second symmetry axis D2.

[0170] Exemplarily, as shown in FIG. 13, the 10 sub-pixels P surrounding the first color sub-pixel P1 include 5 second color sub-pixels P2 and 5 third color sub-pixels P3. The 5 second color sub-pixels P2 and the 5 first color sub-pixels P1 are symmetrically arranged relative to the second symmetry axis D2.

[0171] The number ratio of the first color sub-pixels P1, the second color sub-pixels P2 and the third color sub-pixels P3 in the plurality of sub-pixels P included in the display panel 10 is 1:2:2.

[0172] The pixel arrangement manner is adopted in the display panel 10, and the number of red sub-pixels and green sub-pixels (the second color sub-pixels P2 and the third color sub-pixels P3) in the display panel 10 is greater than the number of blue sub-pixels (the first color sub-pixels P1), the number of blue sub-pixels can be reduced to reduce the luminous intensity of the blue sub-pixels, thereby slowing down the decay rate of the blue sub-pixels, balancing the service life of the sub-pixels P of different luminous colors in the display panel 10, and further prolonging the service life of the display panel 10. At the same time, since the luminous efficiency of the blue sub-pixels is lower than that of the red sub-pixels and the green sub-pixels, reducing the number of blue sub-pixels can reduce unnecessary energy consumption and improve the energy efficiency ratio of the display panel 10.

[0173] In some embodiments, as shown in FIG. 13, in the first sub-pixel column L1, the distance r5 between the geometric center of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1, the distance r7 between the geometric center of the first color sub-pixel P1 and the third color sub-pixel P3 adjacent to the first color sub-pixel P1, and the distance r6 between the geometric center of the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 are the same or substantially the same.

[0174] In this case, the projection shape of the first color sub-pixel P1 and the second color sub-pixel P2 on the display surface of the display panel 10 can be circular, and the projection shape of the third color sub-pixel P3 on the display surface of the display panel 10 can be elliptical. In the first sub-pixel column L1, the distance between the geometric centers of any two adjacent sub-pixels P is the same, that is, r5=r6=r7.

[0175] Based on this, the outer dimensions of the projection shapes of the first color sub-pixel P1 and the second color sub-pixel P2 on the display surface of the display panel 10 are the same, or the outer dimensions of the projection shapes of the first color sub-pixel P1 and the second color sub-pixel P2 on the display surface of the display panel 10 can also be different. The outer dimensions referred to herein can refer to the diameter of the projection shape (circular) on the display surface of the display panel 10.

[0176] The size of the long axis of the projection shape (elliptical shape) of the third color sub-pixel P3 on the display surface can be the same as the size of the outer shape of the projection shape (circular shape) of the first color sub-pixel P1 and / or the second color sub-pixel P2 on the display surface, or can be different from the size of the outer shape of the projection shape (circular shape) of the first color sub-pixel P1 and the second color sub-pixel P2 on the display surface.

[0177] In the first sub-pixel column L1, the pitch between the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 is j9; the pitch between the first color sub-pixel P1 and the third color sub-pixel P3 adjacent to the first color sub-pixel P1 is j7; and the pitch between the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 is j8.

[0178] The pitch described herein can refer to the distance between the boundaries of two adjacent sub-pixels P along the line connecting the geometric centers of the projection shapes of the two adjacent sub-pixels P on the display surface of the display panel 10.

[0179] In some examples, the size of the long axis of the projection shape (elliptical shape) of the third color sub-pixel P3 on the display surface, the size of the outer shape of the projection shape (circular shape) of the first color sub-pixel P1 on the display surface, and the size of the outer shape of the projection shape (circular shape) of the second color sub-pixel P2 on the display surface are all the same, j7=j8=j9.

[0180] In other examples, the size of the long axis of the projection shape (elliptical shape) of the third color sub-pixel P3 on the display surface, the size of the outer shape of the projection shape (circular shape) of the first color sub-pixel P1 on the display surface, and the size of the outer shape of the projection shape (circular shape) of the second color sub-pixel P2 on the display surface are not all the same, j7, j8, and j9 are not all the same.

[0181] In yet other examples, the size of the long axis of the projection shape (elliptical shape) of the third color sub-pixel P3 on the display surface, the size of the outer shape of the projection shape (circular shape) of the first color sub-pixel P1 on the display surface, and the size of the outer shape of the projection shape (circular shape) of the second color sub-pixel P2 on the display surface are not all the same, j7, j8, and j9 are not all the same.

[0182] In the embodiment, by equalizing the distances between the geometric centers of the sub-pixels P in the first sub-pixel column L1, the sub-pixels P in the first sub-pixel column L1 are uniformly distributed in the arrangement direction of the first sub-pixel column L1, which can avoid color deviation and unnatural color transition when the display panel 10 displays an image, and help to improve the color accuracy and consistency of the image.

[0183] Based on this, in some embodiments, as shown in FIG. 13, the two first sub-pixel columns L1 respectively located on both sides of the second sub-pixel column L2 and adjacent to the second sub-pixel column L2 are respectively the first target sub-pixel column L11 and the second target sub-pixel column L12.

[0184] In some examples, in the second sub-pixel column L2, the geometric center of each second color sub-pixel P2 is located at the midpoint of the line connecting the geometric center of one third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the first target sub-pixel column L11 and the geometric center of one third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the second target sub-pixel column L12.

[0185] As shown in FIG. 13, in the second sub-pixel column L2, the distance between the geometric center of each second color sub-pixel P2 and the geometric center of one third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the first target sub-pixel column L11 is t3; the distance between the geometric center of each second color sub-pixel P2 and the geometric center of one third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the second target sub-pixel column L12 is t4; t3=t4.

[0186] In other examples, as shown in FIG. 13, in the second sub-pixel column L2, the geometric center of the third color sub-pixel P3 is located at the midpoint of the line connecting the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the first target sub-pixel column L11 and the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the second target sub-pixel column L12.

[0187] As shown in FIG. 13, the distance between the geometric center of each third color sub-pixel P3 in the second sub-pixel column L2 and the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the first target sub-pixel column L11 is t5; the distance between the geometric center of each third color sub-pixel P3 in the second sub-pixel column L2 and the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the second target sub-pixel column L12 is t6; t5=t6.

[0188] In yet some examples, as shown in FIG. 13, in the second sub-pixel column L2, the geometric center of each second color sub-pixel P2 is located at the midpoint of the line connecting the geometric center of one third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the first target sub-pixel column L11 and the geometric center of one third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the second target sub-pixel column L12; and in the second sub-pixel column L2, the geometric center of the third color sub-pixel P3 is located at the midpoint of the line connecting the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the first target sub-pixel column L11 and the geometric center of one second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the second target sub-pixel column L12.

[0189] In this way, in the display panel 10, the distance between the geometric centers of any two adjacent sub-pixels P in the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 is the same or substantially the same, and the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1 are uniformly distributed, which is conducive to improving the uniformity of the pixel density of the display panel 10, so that the image details can be fully displayed, thereby making the image displayed by the display panel 10 visually present higher resolution and clearer image.

[0190] FIG. 14 is an enlarged structural view of one pixel group in the display panel 10 shown in FIG. 12, each pixel group comprising one first color sub-pixel P1 and a plurality of second color sub-pixels P2 and a plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1.

[0191] Exemplarily, in the case that the plurality of sub-pixels P in the display panel 10 adopt the arrangement mode shown in FIGS. 12 and 13, as shown in FIG. 14, the first included angle α1 of the hexagon formed by the line connecting the geometric centers of the second color sub-pixels P2 and the third color sub-pixels P3 surrounding the first color sub-pixel P1 can be 108°, and the second included angle α2 can be 143°. Of course, the angles of the first included angle α1 and the second included angle α2 can also be other angles, which are only exemplary descriptions of one possible implementation of the present disclosure and are not limitations of the present disclosure.

[0192] By adjusting the arrangement of each sub-pixel P in the first sub-pixel column L1, the distances of the geometric centers of each sub-pixel P in the first sub-pixel column L1 are equal, or the intervals are equal, or the intervals of part of the sub-pixels P are smaller, the first included angle a1 and the second included angle a2 formed in the hexagon surrounded by the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 around the first color sub-pixel P1 can be changed within a certain range, thereby improving the arrangement gap of the sub-pixels P in the display panel 10, reducing the granularity of the display picture, and improving the display effect.

[0193] FIG. 15 is a plan view of a display panel 10 according to some embodiments of the present disclosure, and FIG. 16 is an enlarged view of a part of the display panel 10 shown in FIG. 15.

[0194] In some embodiments, as shown in FIGS. 15 and 16, in the display panel 10, different from the display panel 10 shown in FIG. 12, in the first sub-pixel column L1, the distance r8 between the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 is smaller than the distance r7 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1. That is, (r8) < (r7).

[0195] Exemplarily, the projection shapes of the first color sub-pixel P1 and the second color sub-pixel P2 in the first sub-pixel column L1 on the display surface of the display panel 10 can be circular. In this case, the outer size of the projection shape of the first color sub-pixel P1 on the display surface is larger than the outer size of the projection shape of the second color sub-pixel P2 on the display surface.

[0196] With such a design, in the first sub-pixel column L1, the arrangement of the second color sub-pixel P2 and the third color sub-pixel P3 is more compact, and the sizes of the second color sub-pixel P2 and the third color sub-pixel P3 are smaller than that of the first color sub-pixel P1, which helps to reduce the color difference and color block phenomenon of color transition when the display panel 10 displays a picture, makes the color transition more smooth and natural, and helps to improve the color accuracy and color restoration degree of the display panel 10 in displaying an image.

[0197] Exemplarily, as shown in FIG. 16, in the first sub-pixel column L1, the ratio of the distance r8 between the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 to the distance r7 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 is greater than one half. That is, (r8) / (r7) > 1 / 2.

[0198] For example, as shown in FIG. 16, the ratio of the distance between the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 to the distance between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 in the first sub-pixel column L1 is two-thirds. That is, (r8) / (r7) = 2 / 3.

[0199] The distance r8 between the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 and the distance r7 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 in the first sub-pixel column L1 can be adaptively designed according to actual needs.

[0200] By adjusting the arrangement of each sub-pixel P in the first sub-pixel column L1, the distance r8 between the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the first sub-pixel column L1 changes with the distance r7 between the geometric centers of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1. Specifically, the distance r8 can be adaptively designed according to different application scenarios of the display panel 10, so as to ensure the display quality of the display panel 10 and make the design of the display panel 10 more flexible and suitable for more different application scenarios.

[0201] FIG. 17 is an enlarged structural diagram of one pixel group in the display panel 10 shown in FIG. 15, each pixel group including one first color sub-pixel P1, and a plurality of second color sub-pixels P2 and a plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1.

[0202] For example, in the case where the plurality of sub-pixels P in the display panel 10 adopt the arrangement shown in FIGS. 15 and 16, as shown in FIG. 17, the first included angle a1 of the hexagon formed by the connecting line of the geometric centers of the second color sub-pixels P2 and the third color sub-pixels P3 surrounding the first color sub-pixel P1 can be 117°, and the second included angle a2 can be 127°. Of course, the angles of the first included angle a1 and the second included angle a2 can also be other angles, which are only exemplary descriptions of one possible embodiment of the present disclosure and are not limitations of the present disclosure.

[0203] By adjusting the arrangement of each sub-pixel P in the first sub-pixel column L1, the distances of the geometric centers of each sub-pixel P in the first sub-pixel column L1 are equal, or the intervals are equal, or the intervals of part of the sub-pixels P are smaller, so that the first included angle a1 and the second included angle a2 formed in the hexagon formed by the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 surrounding the first color sub-pixel P1 change within a certain range, thereby improving the arrangement gap of the sub-pixels P in the display panel 10, reducing the granularity of the display picture, and improving the display effect.

[0204] FIG. 18 is a plan view of a display panel 10 according to some embodiments of the present disclosure, and FIG. 19 is an enlarged view of a part of the display panel 10 shown in FIG. 18.

[0205] In some embodiments, as shown in FIGS. 18 and 19, the projection shape of the first color sub-pixel P1 on the display surface of the display panel 10 can be a hexagon, the projection shape of the second color sub-pixel P2 and the third color sub-pixel P3 located in the first sub-pixel column L1 on the display surface of the display panel 10 can be a trapezoid, and the projection shape of the second color sub-pixel P2 and the third color sub-pixel P3 located in the second sub-pixel column L2 on the display surface of the display panel 10 can be a rhombus. The distance described herein can refer to the interval between the boundaries of the orthographic projection of the sub-pixel P on the display surface of the display panel 10.

[0206] For example, as shown in FIG. 19, in the first sub-pixel column L1, the minimum distance j11 between the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1, the minimum distance j9 between the first color sub-pixel P1 and the third color sub-pixel P3 adjacent to the first color sub-pixel P1, and the minimum distance j10 between the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 are the same or substantially the same. The distance described herein can refer to the interval between the boundaries of the orthographic projection of the sub-pixel P on the display surface of the display panel 10.

[0207] As shown in FIG. 19, in the first sub-pixel column L1, the opposite boundaries of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 can be parallel to each other or form a certain included angle. In the case where the opposite boundaries of the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 are parallel to each other, the distance between the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 is unique.

[0208] Correspondingly, in the first sub-pixel column L1, the boundaries opposite to the first color sub-pixel P1 and the third color sub-pixel P3 adjacent to the first color sub-pixel P1 can be parallel to each other or form a certain angle, and the boundaries opposite to the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 can be parallel to each other or form a certain angle.

[0209] Exemplarily, in the first sub-pixel column L1, in the case that the boundaries opposite to the first color sub-pixel P1 and the second color sub-pixel P2 adjacent to the first color sub-pixel P1 are parallel to each other, the boundaries opposite to the first color sub-pixel P1 and the third color sub-pixel P3 adjacent to the first color sub-pixel P1 are parallel to each other, and the boundaries opposite to the second color sub-pixel P2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 are parallel to each other, the distance between any two adjacent sub-pixels P in the first sub-pixel column L1 is the same, that is, j9=j10=j11.

[0210] In this way, the intervals of the sub-pixels P in the first sub-pixel column L1 are equal, the sub-pixels P in the first sub-pixel column L1 are uniformly distributed in the arrangement direction of the first sub-pixel column L1, and when the display panel 10 displays an image, the color deviation and unnatural color transition can be avoided, which helps to improve the color accuracy and consistency of the image. At the same time, the equal-interval arrangement of the sub-pixels P helps to maintain the uniformity of the pixel density, and each sub-pixel P in the first sub-pixel column L1 is distributed at the same density, so that the image details can be fully displayed, thereby making the image displayed by the display panel 10 visually present higher resolution and clearer image.

[0211] Based on this, in some embodiments, as shown in FIG. 19, in the first sub-pixel column L1 and the second sub-pixel column L2 adjacent to the first sub-pixel column L1, the minimum distance j14 between the second color sub-pixel P2 in the second sub-pixel column L2 and the first color sub-pixel P1 adjacent to the second color sub-pixel P2 in the first sub-pixel column L1 is the same as or substantially the same as the minimum distance j12 between the second color sub-pixel P2 in the second sub-pixel column L2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the first sub-pixel column L1.

[0212] In the first sub-pixel column L1 and the second sub-pixel column L2 adjacent to the first sub-pixel column L1, the boundaries opposite to the second color sub-pixel P2 in the second sub-pixel column L2 and the first color sub-pixel P1 adjacent to the second color sub-pixel P2 in the first sub-pixel column L1 can be parallel or substantially parallel, and the boundaries opposite to the second color sub-pixel P2 in the second sub-pixel column L2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the first sub-pixel column L1 can be parallel or substantially parallel.

[0213] In some examples, as shown in FIG. 19, in the first sub-pixel column L1 and the second sub-pixel column L2 adjacent to the first sub-pixel column L1, the minimum distance j13 between the third color sub-pixel P3 within the second sub-pixel column L2 and the first color sub-pixel P1 adjacent to the third color sub-pixel P3 in the first sub-pixel column L1 is the same as or approximately the same as the minimum distance j12 between the third color sub-pixel P3 within the second sub-pixel column L2 and the second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the first sub-pixel column L1.

[0214] In the first sub-pixel column L1 and the second sub-pixel column L2 adjacent to the first sub-pixel column L1, the opposite boundaries of the third color sub-pixel P3 within the second sub-pixel column L2 and the first color sub-pixel P1 adjacent to the third color sub-pixel P3 in the first sub-pixel column L1 can be parallel or approximately parallel to each other.

[0215] In yet some examples, as shown in FIG. 19, in the first sub-pixel column L1 and the second sub-pixel column L2 adjacent to the first sub-pixel column L1, the minimum distance j14 between the second color sub-pixel P2 within the second sub-pixel column L2 and the first color sub-pixel P1 adjacent to the second color sub-pixel P2 in the first sub-pixel column L1 is the same as or approximately the same as the minimum distance j12 between the second color sub-pixel P2 within the second sub-pixel column L2 and the third color sub-pixel P3 adjacent to the second color sub-pixel P2 in the first sub-pixel column L1; and the minimum distance j13 between the third color sub-pixel P3 within the second sub-pixel column L2 and the first color sub-pixel P1 adjacent to the third color sub-pixel P3 in the first sub-pixel column L1 is the same as or approximately the same as the minimum distance j12 between the third color sub-pixel P3 within the second sub-pixel column L2 and the second color sub-pixel P2 adjacent to the third color sub-pixel P3 in the first sub-pixel column L1.

[0216] In this way, in the display panel 10, in the first color sub-pixel P1 and the plurality of second color sub-pixels P2 and the plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1, the distance between any two adjacent sub-pixels P is the same or approximately the same, the distance between any two adjacent sub-pixels P in the plurality of sub-pixels P in the display panel 10 is the same or approximately the same, each sub-pixel P in the display panel 10 is uniformly distributed, the uniformity of the pixel density of the display panel 10 is good, so that the image details can be fully displayed, thereby making the image displayed by the display panel 10 visually present higher resolution and clearer image.

[0217] FIG. 20 is an enlarged structural view of one pixel group in the display panel 10 shown in FIG. 18, each pixel group including one first color sub-pixel P1 and a plurality of second color sub-pixels P2 and a plurality of third color sub-pixels P3 surrounding the first color sub-pixel P1.

[0218] Exemplarily, in the case that the plurality of sub-pixels P in the display panel 10 adopt the arrangement manner as shown in FIGS. 18 and 19, as shown in FIG. 20, the first included angle α1 of the hexagon formed by the connecting line surrounding the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 of the first color sub-pixel P1 can be 115°, and the second included angle α2 can be 129°. Of course, the angles of the first included angle α1 and the second included angle α2 can also be other angles, which are only exemplary descriptions of one possible embodiment of the present disclosure, and not limitations of the present disclosure.

[0219] By adjusting the arrangement manner of each sub-pixel P in the first sub-pixel column L1, the angles of the first included angle α1 and the second included angle α2 formed in the hexagon surrounded by the connecting line surrounding the geometric centers of the second color sub-pixel P2 and the third color sub-pixel P3 of the first color sub-pixel P1 can be changed within a certain range, so as to improve the arrangement gap of the sub-pixels P in the display panel 10, reduce the granularity of the display picture, and improve the display effect.

[0220] Based on any of the above embodiments, the arrangement manner of the plurality of sub-pixels P in the display panel 10 is different, and the outermost sub-pixel P in the display panel 10 is also different.

[0221] In some examples, as shown in FIGS. 1, 6 and 9, in the case that the first sub-pixel column L1 includes the first color sub-pixel P1 and the second color sub-pixel P2, and the second sub-pixel column L2 includes the third color sub-pixel P3, in the plurality of first sub-pixel columns L1 and second sub-pixel columns L2 alternately arranged along the first direction X, if the outermost sub-pixel column L along the first direction X is the second sub-pixel column L2, then there will be display color deviation at the edge portion of the side of the display panel 10 where the outermost sub-pixel column L is the second sub-pixel column L2.

[0222] For example, the third color is green or red, then when the display panel 10 displays a white picture, the display color of the display panel 10 at the side where the edge sub-pixel column L is the second sub-pixel column L2 is green or red, and the display panel 10 has edge color deviation.

[0223] In other examples, as shown in FIGS. 12, 15, and 18, in a case where the first sub-pixel column L1 includes the first color sub-pixel P1, the second color sub-pixel P2, and the third color sub-pixel P3 arranged periodically, and the second sub-pixel column L2 includes the second color sub-pixel P2 and the third color sub-pixel P3 arranged alternately, in the plurality of columns of the first sub-pixel column L1 and the second sub-pixel column L2 arranged alternately along the first direction X, if the outermost sub-pixel column L along the first direction X is the second sub-pixel column L2, the edge portion of the display panel 10 on the side where the outermost sub-pixel column L is the second sub-pixel column L2 can have display color deviation.

[0224] For example, one of the second color and the third color is green, and the other is red. In this case, when the display panel 10 displays a white screen, the display color of the display panel 10 on the side where the edge sub-pixel column L is the second sub-pixel column L2 is yellow, and the display panel 10 has edge color deviation.

[0225] Based on this, in some embodiments, as shown in FIGS. 1, 6, 9, 12, 15, and 18, the display panel 10 includes a plurality of columns of sub-pixel columns L arranged at intervals along the first direction X. In the plurality of columns of sub-pixel columns L, at least one of the two columns of sub-pixel columns L located on the outermost sides along the first direction X is the first sub-pixel column L1.

[0226] The part of the display panel 10 other than the arrangement region of the sub-pixels P does not emit light and is visually perceived as black (background color). By arranging the outermost sub-pixel column L on at least one of the two sides of the display panel 10 along the first direction X as the first sub-pixel column L1, in a case where the sub-pixels P closer to the edge portion of the display panel 10 include blue sub-pixels, the color deviation of the edge portion of the display panel 10 on the two sides along the first direction X can be reduced compared to a case where red sub-pixels and / or green sub-pixels are closer to the edge of the display panel 10, because the visual display effect of blue sub-pixels is closer to black than that of red sub-pixels and / or green sub-pixels.
