[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0048] The display panel provided by the embodiment of the present invention sets at least one of the first sub-pixel, the second sub-pixel, and the third sub-pixel as a special-shaped sub-pixel, and the circular arc and the elliptical arc in the shape contour of the special-shaped sub-pixel are connected end to end, thereby increasing the facing distance between the special-shaped sub-pixel and the sub-pixel adjacent to it, thereby improving the sub-pixel stealing and enhancing the display effect of the display panel.

[0049] Figure 1 A schematic diagram of a display panel provided by an embodiment of the present invention, Figure 2 FIG. 1 is a schematic diagram of a special-shaped sub-pixel in an embodiment of the present invention. Figure 1 As shown, the display panel includes a plurality of sub-pixels sp, and the sub-pixels sp include a first sub-pixel sp1, a second sub-pixel sp2, and a third sub-pixel sp3 of different colors; the first sub-pixel sp1, the second sub-pixel sp2, and the third sub-pixel sp3 are respectively one of a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Two first sub-pixels sp1 and two second sub-pixels sp2 constitute a first virtual quadrilateral 10, the two first sub-pixels sp1 are located at a diagonal position of the first virtual quadrilateral 10, the two second sub-pixels sp2 are located at another diagonal position of the first virtual quadrilateral 10, and a third sub-pixel sp3 is located in the first virtual quadrilateral 10; four third sub-pixels sp3 constitute a second virtual quadrilateral 20, and the first sub-pixel sp1 or the second sub-pixel sp2 is located in the second virtual quadrilateral 20; wherein, at least one of the first sub-pixel sp1, the second sub-pixel sp2, and the third sub-pixel sp3 includes a special-shaped sub-pixel spx. The vertex of each virtual quadrilateral is the center of the sub-pixel sp at the vertex position. In the embodiment of the present invention, the first virtual quadrilateral 10 may be an irregular quadrilateral, a parallelogram, or a square, and the second virtual quadrilateral 20 may be a parallelogram or a square.

[0050] Figure 1 In the figure, the first sub-pixel sp1 is illustrated as a special-shaped sub-pixel spx, and the second sub-pixel sp2 and the third sub-pixel sp3 are illustrated as circles. Figure 2 The shape outline of the special-shaped sub-pixel spx includes a circular arc l1 and an elliptical arc l2, and the circular arc l1 and the elliptical arc l2 are connected end to end. The two intersection points of the circular arc l1 and the elliptical arc l2 are the first intersection point W1 and the second intersection point W2. Among them, the length of the circular arc l1 can be half of the circumference of the circle in which it is located, that is, the circular arc l1 is a semi-circular arc, or the length of the circular arc l1 can also be less than or greater than half of the circumference of the circle in which it is located. The length of the elliptical arc l2 can be half of the circumference of the ellipse in which it is located, that is, the elliptical arc l2 is a semi-elliptical arc, or the length of the elliptical arc l2 can also be less than or greater than half of the circumference of the ellipse in which it is located.

[0051] Figure 3 is a schematic diagram of a display panel in the related art, Figure 3In the example, each sub-pixel is a rectangle, and the shape of each sub-pixel can also be a circle. Figure 3 As shown, two first sub-pixels sp1 and two second sub-pixels sp2 constitute a first virtual square 01, the two first sub-pixels sp1 are located at one diagonal position of the first virtual square 01, the two second sub-pixels sp2 are located at another diagonal position of the first virtual square 01, and one third sub-pixel sp3 is located in the first virtual square 01; four third sub-pixels sp3 constitute a second virtual square 02.

[0052] Figure 4 is another schematic diagram of a display panel in the related art, such as Figure 4 As shown, two first sub-pixels sp1 and two second sub-pixels sp2 constitute a first virtual trapezoid 01, the two first sub-pixels sp1 are located at one diagonal position of the first virtual trapezoid 03, the two second sub-pixels sp2 are located at another diagonal position of the first virtual trapezoid 03, and one third sub-pixel sp3 is located in the first virtual trapezoid 03; four third sub-pixels sp3 constitute a second virtual trapezoid 04. Figure 4 The pixel arrangement is equivalent to Figure 3 It is obtained by deformation based on Figure 3 Based on the illustrated pixel arrangement, the first virtual trapezoid 01 and the second virtual trapezoid 02 are formed by adjusting the positions of the sub-pixels, that is, virtual quadrilaterals of different shapes are constructed by moving the positions of the sub-pixels. Figure 4 As shown, the distance between the first sub-pixel sp1 and the second sub-pixel sp2 at the upper bottom of the first virtual trapezoid 01 is small, and there may be a problem of sub-pixel stealth.

[0053] In the embodiment of the present invention, at least one of the three sub-pixels is set as a special-shaped sub-pixel spx, and the shape outline of the special-shaped sub-pixel spx is composed of a circular arc l1 and an elliptical arc l2, and the center position of the special-shaped sub-pixel spx changes according to its shape. The position of the center of the special-shaped sub-pixel spx can be adjusted by designing the shape of the special-shaped sub-pixel spx, so as to achieve a virtual quadrilateral in which it is located in a different shape, without having to meet the shape requirements of the virtual quadrilateral by moving the position of the sub-pixel. The design of the special-shaped sub-pixel spx can make the distance difference between each special-shaped sub-pixel spx and the adjacent sub-pixel in the virtual quadrilateral where it is located small, and the distance between each special-shaped sub-pixel spx and the adjacent sub-pixel is relatively average, which can improve the problem of sub-pixel stealing light. Moreover, in the embodiment of the present invention, the special-shaped sub-pixel spz is composed of a circular arc l1 and an elliptical arc l2, and its luminous boundary is relatively smooth and has no straight edges, which can help reduce diffraction.

[0054] In addition, in some embodiments, the area size of the irregular-shaped sub-pixel spx can be set to be larger than the area size of the virtual circle where the arc l1 is located, so as to increase the aperture ratio of the sub-pixel and improve the life of the sub-pixel.

[0055] In some embodiments, Figure 5 Another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present invention. Figure 5 As shown, the ellipse where the elliptical arc l2 is located is the virtual ellipse 001, and the circle where the arc l1 is located is the virtual circle 002; the virtual ellipse 001 has a major axis z1 and a minor axis z2. The arc l1 intersects with the major axis z1 of the virtual ellipse 001. This embodiment can provide a relatively large area-sized irregular sub-pixel spx, such as the area of ​​the virtual ellipse 001 can be designed to be larger than the area of ​​the virtual circle 002 where the arc l1 is located, and the area size of the irregular sub-pixel spx will be larger than the area of ​​the virtual circle 002 where the arc l1 is located, so that the aperture ratio of the sub-pixel can be increased and the life of the sub-pixel can be improved.

[0056] Figure 6 Another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present invention. Figure 6 As shown, the ellipse where the elliptical arc l2 is located is the virtual ellipse 001, and the circle where the arc l1 is located is the virtual circle 002; the virtual ellipse 001 has a short axis z2. The arc l1 intersects with the extension line of the short axis z2 of the virtual ellipse 001. This embodiment can provide a relatively small area size of a special-shaped sub-pixel spx, such as the area of ​​the virtual ellipse 001 can be designed to be smaller than the area of ​​the virtual circle 002, and the area size of the special-shaped sub-pixel spx will be smaller than the area of ​​the virtual circle 002 where the arc l1 is located. In the case of limited area space in the display panel, reducing the size of the special-shaped sub-pixel spx can increase the size of other color sub-pixels accordingly, and can increase the aperture ratio of other color sub-pixels, thereby balancing the life span differences of different color sub-pixels.

[0057] like Figure 5 As shown, the diameter R of the virtual circle 002 is the minor axis z2 of the virtual ellipse 001. That is to say, the virtual circle 002 is the inscribed circle of the virtual ellipse 001. In this embodiment, the area size of the irregular sub-pixel spz composed of the circular arc l1 and the elliptical arc l2 is relatively large, which can increase the aperture ratio of the sub-pixel and improve the life of the sub-pixel. Moreover, the connection transition between the circular arc l1 and the elliptical arc l2 is smooth, so that the boundary of the irregular sub-pixel spz is relatively smooth, which can reduce diffraction and improve the display effect in the application.

[0058] like Figure 6As shown, the diameter R of the virtual circle 002 is the major axis z1 of the virtual ellipse 001. The virtual ellipse 001 can be considered as an inscribed ellipse of the virtual circle 002. In this embodiment, the area size of the irregular sub-pixel spz composed of the circular arc l1 and the elliptical arc l2 is relatively small, which can leave more space for other color sub-pixels in the entire display area, increase the size of other color sub-pixels, and balance the life span difference of different color sub-pixels. Moreover, the connection transition between the circular arc l1 and the elliptical arc l2 is smooth, so that the boundary of the irregular sub-pixel spz is relatively smooth, which can reduce diffraction and improve the display effect in application.

The circular arc l1 intersects with the major axis z1 of the virtual ellipse 001, and the line between the first intersection point W1 and the second intersection point W1 is the first virtual line segment X1, wherein the length of the first virtual line segment X1 is less than the diameter R of the virtual circle 002. In this embodiment, the length of the circular arc l1 is less than half of the circumference of the virtual circle 002 where it is located. The area of ​​the region enclosed by the first virtual line segment X1 and the circular arc l1 is less than half of the area of ​​the virtual circle 002.

[0060] Optional, such as Figure 7 As shown, the first virtual line segment X1 coincides with the minor axis z2, the length of the elliptical arc l2 is half the circumference of the virtual ellipse 001, and the elliptical arc l2 is a semi-elliptical arc.

The circular arc l1 intersects with the major axis z1 of the virtual ellipse 001, and the line between the first intersection point W1 and the second intersection point W1 is the first virtual line segment X1, and the length of the first virtual line segment X1 is less than the minor axis z2 of the virtual ellipse 001. In this embodiment, the length of the elliptical arc l2 is less than half of the circumference of the virtual ellipse 001 where it is located. The area enclosed by the first virtual line segment X1 and the elliptical arc l2 is less than half of the area of ​​the virtual ellipse 001.

[0062] In other embodiments, Fig. 9 Another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present invention is as follows: Fig. 9As shown, the ellipse where the elliptical arc l2 is located is the virtual ellipse 001, and the circle where the circular arc l1 is located is the virtual circle 002; the virtual ellipse 001 has a major axis z1 and a minor axis z2. The circular arc l1 intersects with the minor axis z2 of the virtual ellipse 001, and the line between the first intersection point W1 and the second intersection point W1 is the first virtual line segment X1, and the length of the first virtual line segment X1 is less than the major axis z1 of the virtual ellipse 001. In this embodiment, the length of the elliptical arc l2 is less than half of the circumference of the virtual ellipse 001 where it is located. The area enclosed by the first virtual line segment X1 and the elliptical arc l2 is less than half of the area of ​​the virtual ellipse 001.

[0063] In some embodiments, Figure 5 and Figure 6 As shown, the ellipse where the elliptical arc l2 is located is the virtual ellipse 001, and the circle where the circular arc l1 is located is the virtual circle 002; the line connecting the two intersection points (the first intersection point W1 and the second intersection point W2) of the circular arc l1 and the elliptical arc l2 passes through the center O of the virtual circle 002. In this special-shaped sub-pixel spz, the line connecting the first intersection point W1 and the second intersection point W2 is the first virtual line segment X1, and the first virtual line segment X1 is the diameter R of the virtual circle 002. The area of ​​the region enclosed by the first virtual line segment X1 and the circular arc l1 is equal to half the area of ​​the virtual circle 002.

[0064] like Fig. 9 It is also shown in FIG. 1 that the line connecting the two intersection points of the circular arc l1 and the elliptical arc l2 passes through the center O of the virtual circle 002 . Fig. 9 In the embodiment, the area of ​​the region enclosed by the first virtual line segment X1 and the arc l1 is equal to half the area of ​​the virtual circle 002 .

[0065] In some embodiments, Fig.10 Another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present invention is as follows: Fig.10 As shown, the circle where the arc l1 is located is the virtual circle 002; the two intersections of the arc l1 and the elliptical arc l2 are the first intersection W1 and the second intersection W2, the line between the first intersection W1 and the center O of the virtual circle 002 is the first line 1-1, the line between the second intersection W2 and the center O of the virtual circle 002 is the second line 1-2, and the angle θ between the first line 1-1 and the second line 1-2 is 180°. In this embodiment, the first line 1-1 and the second line 1-2 are located on a straight line, and the straight line passes through the center O of the virtual circle 002, then the length of the line between the first intersection W1 and the second intersection W2 is equal to the diameter length of the virtual circle 002. The area of ​​the area enclosed by the line between the first intersection W1 and the second intersection W2 and the arc l1 in the irregular sub-pixel spz is half the area of ​​the virtual circle 002.

[0066] In some embodiments, Fig.11 Another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present invention is as follows: Fig.11 As shown, the ellipse where the elliptical arc l2 is located is the virtual ellipse 001, the two intersection points of the circular arc l1 and the elliptical arc l2 are the first intersection point W1 and the second intersection point W2, the line between the first intersection point W1 and the second intersection point W2 is the first virtual line segment X1, and the major axis z1 of the virtual ellipse 001 is perpendicular to the first virtual line segment X1. The irregular sub-pixel spz provided in this embodiment is symmetrical about the major axis z1, and the shape contour of the irregular sub-pixel spz is an axisymmetric figure, and the shape of the irregular sub-pixel spz is relatively more regular. When the sub-pixels are laid out on the entire surface of the display panel, the irregular sub-pixel spz is easier to cooperate with other color sub-pixels, so that the sub-pixel arrangement is more uniform and compact. When the sub-pixel rendering method is used for display, the display effect of the irregular sub-pixel spz in cooperation with other sub-pixels will also be better.

[0067] In one embodiment, the major axis z1 of the virtual ellipse 001 is perpendicular to the first virtual line segment X1, the first virtual line segment X1 coincides with the minor axis of the virtual ellipse 001, and the first virtual line segment X1 is the diameter of the virtual circle where the arc l1 is located. In this implementation, the area of ​​the region enclosed by the first virtual line segment X1 and the elliptical arc l2 is half the area of ​​the virtual ellipse 001, the area of ​​the region enclosed by the first virtual line segment X1 and the arc l1 is half the area of ​​the virtual circle, the area size of the irregular sub-pixel spz is larger than the area of ​​the virtual circle where the arc l1 is located, and an irregular sub-pixel spz with a larger area size can be obtained.

[0068] like Fig.11 As shown, the maximum distance between arc l1 and the first virtual line segment X1 is a 1 , the maximum distance between the elliptical arc l2 and the first virtual line segment X1 is a 2 , a 1 2 ≤3*a 1 The irregular sub-pixel spz is composed of a partial ellipse and a partial circle, and the ellipse part and the circle part are divided by the first virtual line segment X1. 1 2 , then the length of the ellipse along the extension direction of the major axis z1 is greater than the length of the circle. 1 When a is the radius of the virtual circle where the arc l1 is located, the area of ​​the irregular sub-pixel spz can be made larger than the area of ​​the virtual circle where the arc l1 is located. Compared with the circular sub-pixel, the size of the irregular sub-pixel spz is larger, which can improve the sub-pixel aperture ratio. 2 ≤3*a 1 , so that the difference in length between the elliptical part and the circular part along the extension direction of the major axis z1 will not be too large, the overall length of the special-shaped sub-pixel spz will not be too long, and when the area of ​​the special-shaped sub-pixel spz meets the design requirements, it is easier to arrange it in coordination with other sub-pixels, thereby ensuring higher space utilization of the entire display panel.​​

[0069] In some embodiments, 1.1≤a 2 :a 1 ≤1.5.

[0070] In some embodiments, Fig.12 Another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present invention is as follows: Fig.12 As shown, the ellipse where the elliptical arc l2 is located is the virtual ellipse 001, the two intersection points of the circular arc l1 and the elliptical arc l2 are the first intersection point W1 and the second intersection point W2, the line between the first intersection point W1 and the second intersection point W2 is the first virtual line segment X1, and the minor axis z2 of the virtual ellipse 001 is perpendicular to the first virtual line segment X1. The irregular sub-pixel spz provided in this embodiment is symmetrical about the minor axis z2, the shape contour of the irregular sub-pixel spz is an axisymmetric figure, and the shape of the irregular sub-pixel spz is relatively more regular. When the sub-pixels are laid out on the entire surface of the display panel, the irregular sub-pixel spz is easier to cooperate with other color sub-pixels, so that the sub-pixel arrangement is more uniform and compact. When the sub-pixel rendering method is used for display, the display effect of the irregular sub-pixel spz in cooperation with other sub-pixels will also be better.

[0071] In one embodiment, the minor axis z2 of the virtual ellipse 001 is perpendicular to the first virtual line segment X1, the first virtual line segment X1 coincides with the major axis of the virtual ellipse 001, and the first virtual line segment X1 is the diameter of the virtual circle where the arc l1 is located.

The irregular sub-pixel spz is composed of a partial ellipse and a partial circle, and the ellipse part and the circle part are divided by the first virtual line segment X1. Set c 1 Less than c 2 , then the length of the circular part along the extension direction of the minor axis z2 is greater than the length of the elliptical part. 2 When c is the radius of the virtual circle where the arc l1 is located, the area of ​​the irregular sub-pixel spz can be made larger than the area of ​​the virtual ellipse 001 and smaller than the area of ​​the virtual circle where the arc l1 is located. 1 / c2 A certain range is met, so that the shape of the irregular sub-pixel spz will not be too flat, and the area size of the irregular sub-pixel spz will not be too small, which can ensure the reasonable use of the overall space of the display panel.

[0079] In some embodiments, the first sub-pixel sp1 or the second sub-pixel sp2 is a special-shaped sub-pixel spz. In some embodiments, the third sub-pixel sp3 is a special-shaped sub-pixel spz. In some embodiments, part of the first sub-pixel sp1 (or the second sub-pixel sp2) is a special-shaped sub-pixel spz and part is a regular sub-pixel (such as a round or rectangular shape). Figure 1 From the given sub-pixel arrangement, the positions of the first sub-pixel sp1 and the second sub-pixel sp2 can be interchanged. For example, one of the first sub-pixel sp1 and the second sub-pixel sp2 is a red sub-pixel and the other is a blue sub-pixel, and the third sub-pixel sp3 is a green sub-pixel. The following takes the first sub-pixel sp1 as an example of a special-shaped sub-pixel spz for illustration and explanation, and the case where the second sub-pixel sp2 is a special-shaped sub-pixel spz can be understood by reference.

[0080] When sub-pixels form a virtual pattern in the embodiment of the present invention, the center of the sub-pixel is used as the vertex of the virtual pattern. For a circular sub-pixel, the center of the circle is used as the center of the sub-pixel, and for a special-shaped sub-pixel spz, the center of gravity of the outline pattern is used as the center. Fig.17 FIG. 1 is a schematic diagram of the center position of a special-shaped sub-pixel in an embodiment of the present invention. Fig.17As shown, the ellipse where the elliptical arc l2 is located is the virtual ellipse 001, and the circle where the circular arc l1 is located is the virtual circle 002; the virtual ellipse 001 has a major axis z1 and a minor axis z2. The line between the first intersection point W1 and the second intersection point W1 of the circular arc l1 and the elliptical arc l2 is the first virtual line segment X1, the first virtual line segment X1 coincides with the minor axis z2, the first virtual line segment X1 is perpendicular to the major axis z1, and the first virtual line segment X1 is the diameter of the virtual circle 002. In this embodiment, the center of gravity C of the irregular sub-pixel spz is located on the major axis z1, and the center of gravity C is located on the side of the first virtual line segment X1 close to the elliptical arc l2.

[0081] In some embodiments, Fig.18 Schematic diagram of another display panel provided by an embodiment of the present invention. Fig.18 As shown, the display panel includes a third virtual quadrilateral 30, and four first sub-pixels sp1 constitute the third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and there is a first sub-pixel sp1 in the second virtual quadrilateral 20; wherein the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx. The direction from the circular arc l1 to the elliptical arc l2 in the irregular sub-pixel spx is the elliptical arc orientation. In the third virtual quadrilateral 30, the elliptical arc orientations of the two first sub-pixels sp1 located at diagonal positions are perpendicular to each other.

[0082] In other embodiments, Fig.19 Schematic diagram of another display panel provided by an embodiment of the present invention. Fig.19 As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and there is a first sub-pixel sp1 in the second virtual quadrilateral 20; wherein the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx. In the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 at the diagonal positions are parallel to each other. Optionally, as Fig.19 It indicates that the elliptical arcs of two first sub-pixels sp1 located at diagonal positions have the same direction.

[0083] In the embodiment of the present invention, four first sub-pixels sp1 are arranged to form a third virtual quadrilateral 30, a first sub-pixel sp1 is arranged in a third virtual quadrilateral 30, and the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are irregular sub-pixels spz. Since the shape contour of the irregular sub-pixel spz is composed of a circular arc l1 and an elliptical arc l2, the orientation of the elliptical arc in the irregular sub-pixel spz affects the center position of the irregular sub-pixel spz. The elliptical arc orientations of the two first sub-pixels sp1 at the diagonal positions in the third virtual quadrilateral 30 are set to be perpendicular or parallel to each other, so as to form third virtual quadrilaterals 30 of different shapes. Among them, the third virtual quadrilateral 30 can be a parallelogram, an irregular trapezoid or a trapezoid. By designing the shape of the irregular sub-pixel spx, the virtual quadrilateral in which it is located can be of different shapes without having to meet the shape requirements of the virtual quadrilateral by moving the position of the sub-pixel. The design of the irregular sub-pixel spx can make the distance difference between each irregular sub-pixel spx and the adjacent sub-pixel in the virtual quadrilateral where it is located small, and the distance between each irregular sub-pixel spx and the adjacent sub-pixel is relatively average, which can improve the problem of sub-pixel stealing. In addition, the elliptical arc directions of the two first sub-pixels sp1 located at the diagonal position in the third virtual quadrilateral 30 are set to be perpendicular or parallel to each other, so that the multiple first sub-pixels sp1 on the entire surface of the display panel have different elliptical arc directions, which is conducive to improving the color deviation of the display viewing angle and can enhance the wide viewing angle display effect.

[0084] in addition, Fig.18 and Fig.19 In the figure, it is indicated that the first sub-pixels sp1 in the third virtual quadrilateral 30 are also irregular-shaped sub-pixels spx, that is, all the first sub-pixels sp1 are irregular-shaped sub-pixels spx. In some embodiments, the first sub-pixels sp1 in the third virtual quadrilateral 30 are regular-shaped sub-pixels, that is, part of the first sub-pixels sp1 are irregular-shaped sub-pixels spx and part are regular sub-pixels, which will be illustrated in the following related embodiments.

[0085] In some embodiments, Fig.18 or Fig.19As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and there is a first sub-pixel sp1 in the second virtual quadrilateral 20; wherein, the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx. There are four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30; in the four first virtual quadrilaterals 10, the center of the second sub-pixel sp2 is at the same distance from the center of the third sub-pixel sp3. When designing the sub-pixel arrangement, the distance between the first sub-pixel sp1 and the second sub-pixel sp2 can be fine-tuned by adjusting the elliptical arc direction of the first sub-pixel sp1, while the distance between the second sub-pixel sp2 and the third sub-pixel sp3 is not changed, so that the distance between each first sub-pixel sp1 and the second sub-pixel sp2 is relatively average. For example, the fourth virtual quadrilateral 40 constituted by the second sub-pixel sp2 can be set to a square, and there is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40.

[0086] like Fig.18 As shown, on the third virtual quadrilateral 30, the elliptical arcs of two first sub-pixels sp1 adjacent to each other along the first direction x have different directions, and the elliptical arcs of two first sub-pixels sp1 adjacent to each other along the second direction y have the same direction. The first direction x and the second direction y intersect each other. Fig.19 As shown, on the third virtual quadrilateral 30 , the elliptical arcs of two first sub-pixels sp1 adjacent to each other in the first direction x have different directions, and the elliptical arcs of two first sub-pixels sp1 adjacent to each other in the second direction y have different directions. Fig.18 and Fig.19 The embodiment designs the elliptical arc orientation of the first sub-pixel sp1 at the diagonal position on the third virtual quadrilateral 30, and the elliptical arc orientation of the first sub-pixel sp1 adjacent in the first direction x / adjacent in the second direction y, respectively, and can respectively form third virtual quadrilaterals 30 of different shapes. That is, by designing the shape of the irregular sub-pixel spx, the virtual quadrilateral in which it is located is realized to have a different shape, without moving the position of the sub-pixel to meet the shape requirements of the virtual quadrilateral. In addition, setting the first sub-pixels sp1 on the entire surface of the display panel to have different elliptical arc orientations is conducive to improving the color deviation of the display viewing angle, and can enhance the wide viewing angle display effect.

[0087] Data lines and scan lines are arranged in the display panel, and the pixel circuits are connected to the data lines and the scan lines, respectively. Optionally, the first direction x is the row direction, and the second direction y is the column direction. Typically, the first direction x and the second direction y are perpendicular to each other. The scan line extends along the first direction x, and the data line extends along the second direction y; or, the data line extends along the first direction x, and the scan line extends along the second direction y. In the following embodiments, the first direction x and the second direction y can be understood with reference to the description here.

[0088] In one embodiment, Fig.18 In the embodiment, the third virtual quadrilateral 30 is a parallelogram.

[0089] In one embodiment, Fig.19 In the embodiment, the third virtual quadrilateral 30 is an irregular quadrilateral.

[0090] In another implementation, Fig. 20 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig. 20 As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and there is a first sub-pixel sp1 in the second virtual quadrilateral 20; wherein the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx. In the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions have the same orientation. And on the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 adjacent to each other along the first direction x have different orientations, and the elliptical arcs of the two first sub-pixels sp1 adjacent to each other along the second direction y have opposite orientations. In this embodiment, the third virtual quadrilateral 30 is a trapezoid.

[0091] In some embodiments, four first sub-pixels sp1 constitute a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and there is a first sub-pixel sp1 in the second virtual quadrilateral 20; wherein the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx. Fig.18 As shown, in the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 at the diagonal positions are perpendicular to each other. Fig.19 As shown, in the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at diagonal positions are parallel to each other. Fig.18 and Fig.19 In the embodiment, the elliptical arc direction of the first sub-pixel sp1 located on the third virtual quadrilateral 30 has an acute angle with the first direction x. Optionally, the acute angle is 45°. Fig. 20 In the third virtual quadrilateral 30 , the elliptical arcs of the two first sub-pixels sp1 at diagonal positions are parallel to each other, and the elliptical arc of the first sub-pixel sp1 on the third virtual quadrilateral 30 is parallel to or perpendicular to the first direction x.

[0092] Take the case where the first sub-pixel sp1 has the circular arc l1 at the bottom and the elliptical arc l2 at the top as an example, Fig.18 and Fig.19This is equivalent to setting the first sub-pixel sp1 located on the third virtual quadrilateral 30 to be inclined relative to the first direction x. When the first direction x and the second direction y are perpendicular to each other, this is equivalent to setting the irregular sub-pixel spz to be inclined relative to the second direction y. Fig. 20 In the embodiment, it is equivalent to placing the irregular sub-pixel spz upright or inverted. In the embodiment of the present invention, the placement of the irregular sub-pixel spz is designed so that the shape of the first virtual quadrilateral 10 formed by the irregular first sub-pixel sp1 and the second sub-pixel sp2 can be deformed more. For example, a parallelogram or an irregular quadrilateral can be formed, which can balance the distance difference between the first sub-pixel sp1 and other color sub-pixels, making the spacing distance relatively even, and improving the problem of sub-pixel stealing. In addition, setting the entire surface of the display panel with multiple first sub-pixels sp1 having different elliptical arc directions is conducive to improving the color deviation of the display viewing angle and can enhance the wide viewing angle display effect.

[0093] In some embodiments, Fig.18 , Fig.19 or Fig. 20 As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and there is a first sub-pixel sp1 in the second virtual quadrilateral 20; wherein, the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx. The first sub-pixel sp1 in the third virtual quadrilateral 30 is an irregular sub-pixel spx, and the elliptical arc orientation of the first sub-pixel sp1 is different from the elliptical arc orientation of the first sub-pixel sp1 on the third virtual quadrilateral 30. In this embodiment, all the first sub-pixels sp1 in the display panel are arranged to be irregular sub-pixels spx, and the elliptical arc orientation of the irregular sub-pixel spx is arranged to be variable, so that the elliptical arc orientations of adjacent irregular sub-pixels spx are different. The first sub-pixel sp1 is more uniformly distributed in the entire display area of ​​the display panel. When the sub-pixel rendering method is used for display, the display effects of the pixels involved in the first sub-pixel sp1 are less different, and the overall display effect is better.

[0094] like Fig.18 , Fig.19 or Fig. 20As shown, the elliptical arc orientation of the first sub-pixel sp1 located in the third virtual quadrilateral 30 is perpendicular to the elliptical arc orientation of at least one of the four first sub-pixels sp1 constituting the third virtual quadrilateral 30. Such an arrangement enables the first sub-pixel sp1 located in the third virtual quadrilateral 30 to form another third virtual quadrilateral 30 with the other three first sub-pixels sp1, and the shapes of the two third virtual quadrilaterals 30 can be the same. When the display panel provided by this embodiment adopts the sub-pixel rendering method for display, the display effects of each pixel involved in the first sub-pixel sp1 are slightly different, and the overall display effect is better. In addition, setting the display panel to have different elliptical arc orientations for multiple first sub-pixels sp1 on the entire surface of the display panel is conducive to improving the color deviation of the display viewing angle and can enhance the display effect of a wide viewing angle.

[0095] In some embodiments, Fig.18 and Fig.19 As shown, the elliptical arc direction of the first sub-pixel sp1 located on the third virtual quadrilateral 30 has an acute angle with the first direction x; there are four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30; the four first virtual quadrilaterals 10 include at least one first sub-virtual quadrilateral 11. In the first sub-virtual quadrilateral 11: the distances between the centers of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 are not equal, and the distances between the centers of the two second sub-pixels sp2 and the center of the third sub-pixel sp3 are equal. By setting the elliptical arc direction of the first sub-pixel sp1, the distance difference between the two first sub-pixels sp1 and the second sub-pixel sp2 in the first sub-virtual quadrilateral 11 can be balanced, and the problem of stealing light caused by the small distance between the first sub-pixel sp1 and the second pixel sp2 can be improved.

[0096] like Fig.18 and Fig.19 As shown, in the first virtual quadrilateral 11, the distance between the center of a first sub-pixel sp1 and the center of the third sub-pixel sp3 is d 1 The distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is d 2 The distance between the center of the two second sub-pixels sp2 and the center of the third sub-pixel sp3 is d 3 ; where d 1 >d 3 >d 2 In this embodiment, since the elliptical arcs of the first sub-pixel sp1 at the diagonal positions of the first sub-virtual quadrilateral 11 are perpendicular to each other, the first sub-virtual quadrilateral 11 can form an irregular trapezoid, and the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 in the first sub-virtual quadrilateral 11 can be relatively even, which is conducive to improving the problem of sub-pixel stealing.

[0097] In some embodiments, Fig.18 As shown, the first sub-pixel sp1 is a special-shaped sub-pixel spz, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square, the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and there is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40. Among them, the third sub-pixel sp3 is a green sub-pixel, and one of the first sub-pixel sp1 and the second sub-pixel sp2 is a red sub-pixel and the other is a blue sub-pixel. Since the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square, the green sub-pixels can be basically located on the same straight line in the row direction and the column direction, and the green sub-pixels are relatively evenly distributed in the row direction and the column direction. When the sub-pixel rendering method is used for display, the display effect of the straight line in the horizontal and vertical directions will be better. In addition, the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and the second sub-pixels sp2 are basically located on the same straight line in the row direction and the column direction, and are relatively evenly distributed in the row direction and the column direction. On this basis, the first virtual quadrilateral 10 can have different shapes by adjusting the direction of the elliptical arc of the irregular sub-pixel spz, thereby making it easier to achieve a relatively even distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2, thereby achieving the technical effect of improving sub-pixel stealing.

[0098] like Fig.18 As shown, the elliptical arcs of two first sub-pixels sp1 adjacent to each other along the second direction y on the third virtual quadrilateral 30 are oriented in the same direction. The first virtual quadrilateral 10 also includes a second sub-virtual quadrilateral 12. In the second sub-virtual quadrilateral 12, the centers of the two first sub-pixels sp1 are equidistant from the center of the third sub-pixel sp3, and the centers of the two second sub-pixels sp2 are equidistant from the center of the third sub-pixel sp3. The second sub-virtual quadrilateral 12 can be a parallelogram, so that the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 can be relatively even, which is conducive to improving the problem of sub-pixel stealing.

[0099] In some embodiments, Fig.18 As shown, there are two first sub-virtual quadrilaterals 11 and two second sub-virtual quadrilaterals 12 at the location of the third virtual quadrilateral 30. The two first sub-virtual quadrilaterals 11 are adjacent in the second direction y and share a virtual edge, and the two second sub-virtual quadrilaterals 12 are adjacent in the second direction and share a virtual edge. Fig.18In the embodiment, the first sub-pixel sp1 located in the third virtual quadrilateral 30 is a special-shaped sub-pixel spz, and the elliptical arc orientation of the first sub-pixel sp1 located in the third virtual quadrilateral 30 is different from the elliptical arc orientation of the first sub-pixel sp1 located at the vertex position of the third virtual quadrilateral 30. As a result, two first sub-virtual quadrilaterals 11 and two second sub-virtual quadrilaterals 12 of different sizes are formed at the location of the third virtual quadrilateral 30. Among them, in one second sub-virtual quadrilateral 12, the distance between the center of the first sub-pixel sp1 and the center of the third sub-pixel sp3 is d 1 In another second sub-virtual quadrilateral 12, the distance between the center of the first sub-pixel sp1 and the center of the third sub-pixel sp3 is d 4 , d 4 >d 1 In the embodiment of the present invention, by setting the elliptical arc direction of the first sub-pixel sp1, two first sub-virtual quadrilaterals 11 and two second sub-virtual quadrilaterals 12 can be formed at the location of the third virtual quadrilateral 30, and the two second sub-virtual quadrilaterals 12 have different sizes. Through coordination, the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 can be relatively even, which is conducive to improving the problem of sub-pixel stealing.

[0100] like Fig.18 As shown, in the two second sub-virtual quadrilaterals 12 where the third virtual quadrilateral 30 is located, the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions of the second sub-virtual quadrilateral 12 are in opposite directions, and the second sub-virtual quadrilateral 12 can form a parallelogram.

[0101] In some embodiments, Fig.18As shown, the first sub-pixel sp1 is a special-shaped sub-pixel spz, four first sub-pixels sp1 form a third virtual quadrilateral 30, the third virtual quadrilateral 30 is a parallelogram, and the second virtual quadrilateral 20 in the third virtual quadrilateral 30 is a square; among the four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30: two first virtual quadrilaterals 10 are irregular quadrilaterals, and the other two first virtual quadrilaterals 10 are parallelograms. Neither the first sub-virtual quadrilateral 11 nor the second sub-virtual quadrilateral 12 is a trapezoid, which can make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively even, which is conducive to improving the problem of sub-pixel stealing. In the scheme where the third sub-pixel sp3 is a green sub-pixel, one of the first sub-pixel sp1 and the second sub-pixel sp2 is a red sub-pixel and the other is a blue sub-pixel, four third sub-pixels sp3 are set to form a second virtual quadrilateral 20 as a square, so that the green sub-pixels are basically located in the same straight line in the row direction and the column direction, and the green sub-pixels are relatively evenly distributed in the row direction and the column direction. When the sub-pixel rendering method is used for display, the display effect of the straight lines in the horizontal and vertical directions will be better. In addition, the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and there is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40. The second sub-pixels sp2 are basically located in the same straight line in the row direction and the column direction, and the second sub-pixels sp2 are relatively evenly distributed in the row direction and the column direction. On this basis, the first virtual quadrilateral 10 can have different shapes by adjusting the elliptical arc direction of the special-shaped sub-pixel spz, thereby making it easier to achieve a relatively average distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2, thereby achieving the technical effect of improving the sub-pixel stealing.

[0102] In some embodiments, Fig.19 As shown, the elliptical arc directions of two first sub-pixels sp1 adjacent to each other along the second direction y on the third virtual quadrilateral 30 are different. The first sub-pixel sp1 located in the third virtual quadrilateral 30 is a special-shaped sub-pixel spz, and the elliptical arc direction of the first sub-pixel sp1 located in the third virtual quadrilateral 30 is different from the elliptical arc direction of the first sub-pixel sp1 located at the vertex position of the third virtual quadrilateral 30. The first virtual quadrilateral 10 also includes a third sub-virtual quadrilateral 13, in which the center of a first sub-pixel sp1 is at a distance d from the center of the third sub-pixel sp3. 1 The distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is d 5 , d 5 >d 1, the centers of the two second sub-pixels sp2 are at equal distances from the center of the third sub-pixel sp3. In this embodiment, by setting the elliptical arc direction of the first sub-pixel sp1 at the diagonal position on the third sub-virtual quadrilateral 13, the third sub-virtual quadrilateral 13 can be made into an irregular quadrilateral. In this way, the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 on the third sub-virtual quadrilateral 13 can be relatively even, which is conducive to improving the problem of sub-pixel stealing.

[0103] In some embodiments, Fig.19 As shown, the first sub-pixel sp1 is a special-shaped sub-pixel spz, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square, the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and there is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40. In the solution where the third sub-pixel sp3 is a green sub-pixel, one of the first sub-pixel sp1 and the second sub-pixel sp2 is a red sub-pixel and the other is a blue sub-pixel, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is set to be a square, so that the green sub-pixels are basically located on the same straight line in the row direction and the column direction, and the green sub-pixels are relatively evenly distributed in the row direction and the column direction. When the sub-pixel rendering method is used for display, the display effect of the straight line in the horizontal and vertical directions will be better. In addition, the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and the second sub-pixels sp2 are basically located on the same straight line in the row direction and the column direction, and are relatively evenly distributed in the row direction and the column direction. On this basis, the first virtual quadrilateral 10 can have different shapes by adjusting the direction of the elliptical arc of the irregular sub-pixel spz, thereby making it easier to achieve a relatively even distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2, thereby achieving the technical effect of improving sub-pixel stealing.

[0104] like Fig.19 As shown, at the location of the third virtual quadrilateral 30, two first sub-virtual quadrilaterals 11 are adjacent in the first direction x and share a virtual side, and two third sub-virtual quadrilaterals 13 are adjacent in the first direction x and share a virtual side. In the embodiment of the present invention, by setting the elliptical arc direction of the first sub-pixel sp1, two first sub-virtual quadrilaterals 11 and two third sub-virtual quadrilaterals 13 can be formed at the location of the third virtual quadrilateral 30. Through coordination, the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 can be relatively even, which is conducive to improving the problem of sub-pixel stealing.

[0105] like Fig.19As shown, the first sub-pixel sp1 is an irregular sub-pixel spz, the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and there is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40. The four first sub-pixels sp1 form a third virtual quadrilateral 30, the third virtual quadrilateral 30 is a parallelogram, and the second virtual quadrilateral 20 in the third virtual quadrilateral 30 is a square; the four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30 are irregular quadrilaterals. In this embodiment, the first virtual quadrilaterals 10 are all irregular quadrilaterals, which can make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively even, which is conducive to improving the problem of sub-pixel stealing.

[0106] In some embodiments, Fig. 20 As shown, the elliptical arc of the first sub-pixel sp1 located on the third virtual quadrilateral 30 is parallel to or perpendicular to the first direction x; there are four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30; the elliptical arcs of two first sub-pixels sp1 adjacent to each other along the second direction y on the third virtual quadrilateral 30 are in opposite directions, and the first direction x and the second direction y intersect each other. In the first virtual quadrilateral 10, the centers of the two first sub-pixels sp1 are at an equal distance from the center of the third sub-pixel sp3, the centers of the two second sub-pixels sp2 are at an equal distance from the center of the third sub-pixel sp3, and the distance between the center of the first sub-pixel sp1 and the center of the third sub-pixel sp3 is not equal to the distance between the center of the second sub-pixel sp2 and the center of the third sub-pixel sp3. In this embodiment, the elliptical arc orientation of the first sub-pixel sp1 located in the third virtual quadrilateral 30 is perpendicular to the elliptical arc orientation of the first sub-pixel sp1 located at the vertex position of the third virtual quadrilateral 30, so that the first virtual quadrilateral 10 can form an irregular quadrilateral, and the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 can be relatively even. In the first virtual quadrilateral 10, the centers of the two first sub-pixels sp1 are at an equal distance from the center of the third sub-pixel sp3, and the centers of the two second sub-pixels sp2 are at an equal distance from the center of the third sub-pixel sp3. When the sub-pixel rendering method is used for display, the display effects of the pixels involved in the first sub-pixel sp1 are slightly different, and the overall display effect is better.

[0107] like Fig. 20As shown, at the location of the third virtual quadrilateral 30, the centers of the two first sub-pixels sp1 in the first virtual quadrilateral 10 are at an equal distance from the center of the third sub-pixel sp3, and the centers of the two second sub-pixels sp2 are at an equal distance from the center of the third sub-pixel sp3. The first virtual quadrilateral 10 includes a fourth sub-virtual quadrilateral 14 and a fifth sub-virtual quadrilateral 15; in the fourth sub-virtual quadrilateral 14, the center of the first sub-pixel sp1 is at a distance d from the center of the third sub-pixel sp3. 6 In the fifth virtual quadrilateral 15, the distance between the center of the first sub-pixel sp1 and the center of the third sub-pixel sp3 is d 7 , d 7 >d 6 ; At the location of the third virtual quadrilateral 30, two fourth sub-virtual quadrilaterals are adjacent in the second direction and share a virtual side, and two fifth sub-virtual quadrilaterals are adjacent in the second direction and share a virtual side. In this embodiment, by setting the elliptical arc orientation of the first sub-pixel sp1 located in the third virtual quadrilateral 30 and the elliptical arc orientation of the first sub-pixel sp1 located at the vertex position of the third virtual quadrilateral 30 to be perpendicular to each other, two first virtual quadrilaterals 10 can be formed at the location of the third virtual quadrilateral 30, and the centers of the first sub-pixels sp1 of the two first virtual quadrilaterals 10 are not equal to the center of the third sub-pixel sp3. Such a setting can cooperate with the elliptical arc orientation design of the first sub-pixel sp1 to make the arrangement of the three sub-pixels more compact, ensure space utilization, and make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively even.

[0108] In some embodiments, Fig. 20As shown, the first sub-pixel sp1 is a special-shaped sub-pixel spz, four first sub-pixels sp1 constitute a third virtual quadrilateral 30, the third virtual quadrilateral 30 is a trapezoid, and the second virtual quadrilateral 20 in the third virtual quadrilateral 30 is a square; the four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30 are irregular quadrilaterals. In this embodiment, the first virtual quadrilaterals 10 are all irregular quadrilaterals, which can make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively even, which is conducive to improving the problem of sub-pixel stealing light. In the scheme where the third sub-pixel sp3 is a green sub-pixel, one of the first sub-pixel sp1 and the second sub-pixel sp2 is a red sub-pixel and the other is a blue sub-pixel, the four third sub-pixels sp3 are set to constitute the second virtual quadrilateral 20 as a square, which can make the green sub-pixels basically located in the same straight line in the row direction and the column direction. The green sub-pixels are relatively evenly distributed in the row direction and the column direction. When the sub-pixel rendering method is used for display, the display effect of the straight lines in the horizontal and vertical directions will be better. In addition, the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and there is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40. The second sub-pixels sp2 are basically located in the same straight line in the row direction and the column direction, and the second sub-pixels sp2 are relatively evenly distributed in the row direction and the column direction. On this basis, the first virtual quadrilateral 10 can have different shapes by adjusting the direction of the elliptical arc of the irregular sub-pixel spz, thereby making it easier to achieve a relatively even distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2, thereby achieving the technical effect of improving the sub-pixel stealth.

[0109] Fig. 20 In the embodiment, when the center of the second subpixel sp2 and the center of the first subpixel sp1 are located on the same straight line along the first direction x or on the same straight line along the second direction y, the four first virtual quadrilaterals 10 at the position of the third virtual quadrilateral 30 are irregular trapezoids with one right-angled internal angle.

[0110] In some embodiments, Fig.21 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.21As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30, and the first sub-pixel sp1 includes a first type of first sub-pixel sp1-1 and a second type of first sub-pixel sp1-2, the first type of first sub-pixel sp1-1 is a special-shaped sub-pixel spx, and the second type of first sub-pixel sp1-2 has a circular shape. The first sub-pixel sp1 constituting the third virtual quadrilateral 30 is the first type of first sub-pixel sp1-1, and the second type of first sub-pixel sp1-2 is located in the third type of virtual quadrilateral. In this embodiment, one of the two first sub-pixels sp1 at the diagonal position of the first virtual quadrilateral 10 is a special-shaped sub-pixel spx and the other is a regular sub-pixel. The design is coordinated with the elliptical arc direction of the special-shaped sub-pixel spx, and the shape of the first virtual quadrilateral 10 can be adjusted so that the distance between the first sub-pixel sp1 and the second sub-pixel sp2 on the first virtual quadrilateral 10 is relatively average, which can improve the problem of sub-pixel stealth.

[0111] In some embodiments, the area of ​​the first sub-pixel sp1-1 is equal to the area of ​​the second first sub-pixel sp1-2. By designing the shapes of the openings of the pixel definition layers corresponding to the two first sub-pixels sp1, the areas of the two first sub-pixels sp1 can be equal. Such a setting can make the contributions of the two first sub-pixels sp1 to display in conjunction with other color sub-pixels to be substantially the same, and the overall display uniformity is better.

[0112] In some embodiments, Fig.21 As shown, there are four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30; in the first virtual quadrilateral 10, the distances between the centers of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 are unequal, and the distances between the centers of the two second sub-pixels sp2 and the center of the third sub-pixel sp3 are equal. By setting one of the two first sub-pixels sp1 at the diagonal position of the first virtual quadrilateral 10 as a special-shaped sub-pixel spx and the other as a regular sub-pixel, the distances between the centers of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 can be unequal, so that the shape of the first virtual quadrilateral 10 can be adjusted so that the distances between the first sub-pixels sp1 and the second sub-pixels sp2 on the first virtual quadrilateral 10 are relatively average. For example, when the second virtual quadrilateral formed by four third sub-pixels sp3 is a square, and the fourth virtual quadrilateral 40 formed by four second sub-pixels sp2 is a square, the second first sub-pixel sp1-2 is equidistant from the four second sub-pixels sp2 around it, and the first virtual quadrilateral 10 is an irregular quadrilateral, and the distance difference between adjacent first sub-pixels sp1 and second sub-pixels sp2 at different positions is small.

[0113] like Fig.21As shown, the elliptical arc of the first sub-pixel sp1 located on the third virtual quadrilateral 30 has an acute angle with the first direction x; the first sub-pixel sp1 located in the third virtual quadrilateral 30 is circular. In the four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30: in one first virtual quadrilateral 10, the distance between the center of a first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 1 , the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 2 In the two first virtual quadrilaterals 10, the distance between the center of a first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 3 , the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 2 ,h 1 >h 3 In a first virtual quadrilateral 10, the distance between the center of a first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 4 , the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 2 ;h 3 >h 4 In this embodiment, the elliptical arc directions of the first sub-pixels sp1 at the diagonal positions on the third virtual quadrilateral 30 are set to be the same, and the elliptical arc directions of the first sub-pixels sp1 have an acute angle with the first direction x, and three sizes of first virtual quadrilaterals 10 are formed at the location of the third virtual quadrilateral 30. In fact, the three sizes of first virtual quadrilaterals 10 are obtained by adjusting the elliptical arc directions of the first sub-pixels sp1 at the vertex positions of the third virtual quadrilateral 30, which can make the distance between the first sub-pixel sp1 and the second sub-pixel sp2 on the first virtual quadrilateral 10 relatively even, which is conducive to improving the problem of sub-pixel stealth.

[0114] like Fig.21As shown, some of the multiple first sub-pixels sp1 are irregular sub-pixels spz and some are circular sub-pixels. The second virtual quadrilateral 20 formed by four third sub-pixels sp3 is a square. The fourth virtual quadrilateral 40 formed by four second sub-pixels sp2 is a square. There is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40. The first sub-pixels sp1 constituting the third virtual quadrilateral 30 are irregular sub-pixels spz, and the first sub-pixels sp1 located in the third virtual quadrilateral 30 are circular sub-pixels. The third virtual quadrilateral 30 is an irregular quadrilateral, and the second virtual quadrilateral 20 in the third virtual quadrilateral 30 is a square; the four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30 are irregular quadrilaterals. In this embodiment, the first virtual quadrilaterals 10 are all irregular quadrilaterals, which can make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively even, which is conducive to improving the problem of sub-pixel stealing light.

[0115] In other embodiments, Fig. 22 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig. 22 As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30, and the first sub-pixels sp1 include a first type of first sub-pixel sp1-1 and a second type of first sub-pixel sp1-2. The first type of first sub-pixel sp1-1 is a special-shaped sub-pixel spx, and the second type of first sub-pixel sp1-2 has a circular shape. The first sub-pixels sp1 constituting the third virtual quadrilateral 30 are the first type of first sub-pixel sp1-1, and the second type of first sub-pixel sp1-2 is located in the third virtual quadrilateral. The elliptical arc of the first sub-pixel sp1 located on the third virtual quadrilateral 30 is parallel to or perpendicular to the first direction x, Fig. 22 In the four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30: in two first virtual quadrilaterals 10, the distance between the center of a first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 5 , the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 6 In the other two first virtual quadrilaterals 10, the distance between the center of a first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 7 , the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h 6 ,h 5 >h 7 Optional, h 6 >h 7 , or it can also be h 6 =h 7. In this embodiment, the third virtual quadrilateral 30 is a trapezoid, and the four first virtual quadrilaterals 10 at its position are irregular quadrilaterals. Two irregular first virtual quadrilaterals 10 are obtained by adjusting the elliptical arc orientation of the first sub-pixel sp1 at the vertex position of the third virtual quadrilateral 30, so that the distance between the first sub-pixel sp1 and the second sub-pixel sp2 on the first virtual quadrilateral 10 is relatively even, which is beneficial to improving the problem of sub-pixel stealing. In addition, setting the entire surface of the display panel with multiple first sub-pixels sp1 having different elliptical arc orientations is beneficial to improving the color deviation of the display viewing angle and can enhance the wide viewing angle display effect.

[0116] In addition, Fig. 22 In the embodiment, there are four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30; in the four first virtual quadrilaterals 10, the center of the second sub-pixel sp2 is equidistant from the center of the third sub-pixel sp3. The fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and there is a second virtual quadrilateral 20 in the fourth virtual quadrilateral 40. Among them, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square. In the scheme where the third sub-pixel sp3 is a green sub-pixel, one of the first sub-pixel sp1 and the second sub-pixel sp2 is a red sub-pixel and the other is a blue sub-pixel, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square, so that the green sub-pixels are basically located on the same straight line in the row direction and the column direction. The green sub-pixels are relatively evenly distributed in the row direction and the column direction. When the sub-pixel rendering method is used for display, the display effect of the straight lines in the horizontal and vertical directions will be better.

[0117] Fig. 22 In the embodiment, when the center of the second sub-pixel sp2 and the center of the first sub-pixel sp1 are located on the same straight line along the second direction y, the four first virtual quadrilaterals 10 at the position of the third virtual quadrilateral 30 are irregular quadrilaterals with two right-angled internal angles. Fig.23 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.23As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and there is a first sub-pixel sp1 in the second virtual quadrilateral 20. The display panel includes a fourth virtual quadrilateral 40, and four second sub-pixels sp2 constitute the fourth virtual quadrilateral 40; a second virtual quadrilateral 20 is located in the fourth virtual quadrilateral 40, and there is a second sub-pixel sp2 in the second virtual quadrilateral 20. Among them, the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx, and the four second sub-pixels sp2 constituting the fourth virtual quadrilateral 40 are all irregular sub-pixels spx. In the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 at the diagonal positions are perpendicular to each other. In the fourth virtual quadrilateral 40, the elliptical arcs of the two second sub-pixels sp2 at the diagonal positions are perpendicular to each other. In this embodiment, the first sub-pixel sp1 and the second sub-pixel sp2 are both set to be irregular sub-pixels spx, which can make the shape of the first virtual quadrilateral 10 more varied. By designing the direction of the elliptical arc of the irregular sub-pixel spx, the distance between the first sub-pixel sp1 and the second sub-pixel sp2 can be fine-tuned, so that the distance between each first sub-pixel sp1 and the second sub-pixel sp2 is relatively even, which can improve the problem of sub-pixel stealth.

[0118] In some embodiments, Fig.23 In the embodiment, the second virtual quadrilateral 20 formed by four third sub-pixels sp3 is a square.

[0119] In another embodiment, in the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 at the diagonal positions are parallel to each other; in the fourth virtual quadrilateral 40, the elliptical arcs of the two second sub-pixels sp2 at the diagonal positions are parallel to each other.

[0120] In some embodiments, Fig.23 As shown, on the third virtual quadrilateral 30, the elliptical arcs of two adjacent first sub-pixels sp1 along the first direction x have different orientations, and the elliptical arcs of two adjacent first sub-pixels sp1 along the second direction y have different orientations; the first direction intersects the second direction; and / or, on the fourth virtual quadrilateral 40, the elliptical arcs of two adjacent second sub-pixels sp2 along the first direction x have different orientations, and the elliptical arcs of two adjacent second sub-pixels sp2 along the second direction y have different orientations. Such an arrangement can make the distance between each first sub-pixel sp1 and the second sub-pixel sp2 in the entire display area of ​​the display panel relatively even, which can improve the problem of sub-pixel stealing. In addition, setting the display panel to have multiple first sub-pixels sp1 with different elliptical arc orientations is conducive to improving the color deviation of the display viewing angle and can enhance the wide viewing angle display effect.

[0121] In some embodiments, Fig.23 As shown, the first sub-pixel sp1 in the third virtual quadrilateral 30 is an irregular sub-pixel spx, and the direction of the elliptical arc of the first sub-pixel sp1 is different from the direction of the elliptical arc of the first sub-pixel sp1 on the third virtual quadrilateral 30; the second sub-pixel sp2 in the fourth virtual quadrilateral 40 is an irregular sub-pixel spx, and the direction of the elliptical arc of the second sub-pixel sp2 is different from the direction of the elliptical arc of the second sub-pixel sp2 on the fourth virtual quadrilateral 40.

[0122] In other embodiments, Fig.24 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.24 As shown, four first sub-pixels sp1 constitute a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and a first sub-pixel sp1 is located in the second virtual quadrilateral 20. The display panel includes a fourth virtual quadrilateral 40, and four second sub-pixels sp2 constitute the fourth virtual quadrilateral 40; a second virtual quadrilateral 20 is located in the fourth virtual quadrilateral 40, and a second sub-pixel sp2 is located in the second virtual quadrilateral 20. Among them, the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all irregular sub-pixels spx, and the four second sub-pixels sp2 constituting the fourth virtual quadrilateral 40 are all irregular sub-pixels spx. Among them, the shape outline of the first sub-pixel sp1 located in the third virtual quadrilateral 30 is circular; the shape outline of the second sub-pixel sp2 located in the fourth virtual quadrilateral 40 is circular. In this embodiment, some of the multiple first sub-pixels sp1 are irregular sub-pixels spx and some are circular sub-pixels, and some of the multiple second sub-pixels sp2 are irregular sub-pixels spx and some are circular sub-pixels. The distance between the first sub-pixel sp1 and the second sub-pixel sp2 can also be fine-tuned by designing the directions of the elliptical arcs of the first sub-pixel sp1 and the second sub-pixel sp2, so that the distance between each first sub-pixel sp1 and the second sub-pixel sp2 is relatively even, which can improve the problem of sub-pixel stealing.

[0123] In other embodiments, the plurality of first sub-pixels sp1 in the display panel are all irregular sub-pixels spx, and some of the plurality of second sub-pixels sp2 are irregular sub-pixels spx and some are circular sub-pixels. In other embodiments, the plurality of second sub-pixels sp2 in the display panel are all irregular sub-pixels spx, and some of the plurality of first sub-pixels sp1 are irregular sub-pixels spx and some are circular sub-pixels. No further drawings are provided for illustration.

[0124] In some embodiments, Fig.25 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.25As shown, two first sub-pixels sp1 and two second sub-pixels sp2 constitute a first virtual quadrilateral 10, the two first sub-pixels sp1 are located at one diagonal position of the first virtual quadrilateral 10, the two second sub-pixels sp2 are located at another diagonal position of the first virtual quadrilateral 10, and a third sub-pixel sp3 is located in the first virtual quadrilateral 10; four third sub-pixels sp3 constitute a second virtual quadrilateral 20, and the first sub-pixel sp1 or the second sub-pixel sp2 is located in the second virtual quadrilateral 20. The third sub-pixels sp3 constituting the second virtual quadrilateral 20 are all irregular sub-pixels spx. In this embodiment, the third sub-pixel sp3 is set as an irregular sub-pixel spz. When the three sub-pixels are closely arranged, the distance between the third sub-pixel spz and the other color sub-pixels can be adjusted by adjusting the elliptical arc direction of the irregular sub-pixel spz, so that the distance between adjacent and different color sub-pixels is relatively average, which can improve the problem of sub-pixel stealing brightness.

[0125] like Fig.25 As shown, the elliptical arcs of the four third sub-pixels sp3 on the second virtual quadrilateral 20 are oriented in different directions, and the elliptical arcs of the two third sub-pixels sp3 located at the diagonal positions of the second virtual quadrilateral 20 are oriented in opposite directions. Such an arrangement can make the arrangement of the three sub-pixels more compact, thereby improving the space utilization of the display panel. Moreover, the arrangement of the multiple third sub-pixels sp3 on the entire surface of the display panel with different elliptical arc orientations is conducive to improving the color deviation of the display viewing angle, and can improve the display effect of a wide viewing angle.

[0126] In some embodiments, the first virtual quadrilateral 10 is a square, and the second virtual quadrilateral 20 is a parallelogram. Optionally, the second virtual quadrilateral 20 is a rectangle. Such an arrangement enables the third sub-pixels sp3 to be evenly distributed in the first direction x and the second direction y. Since the human eye is more sensitive to green light, when the third sub-pixel sp3 is a green sub-pixel, the overall display effect can be better.

[0127] Combination Fig.13 From the perspective of the display panel, the pixel definition layer 05 includes a plurality of openings K, a sub-pixel sp includes an opening K; the opening K includes a first opening K1, and the irregular sub-pixel spx includes the first opening K1. The sub-pixel sp includes a first electrode 41, a light-emitting layer 42, and a second electrode 43. In some embodiments, the area of ​​the light-emitting layer 42 in the irregular sub-pixel spx is greater than the area of ​​the first opening K1.

[0128] Fig.26 A simplified schematic diagram of another display panel provided by an embodiment of the present invention, Fig.26 The pattern 42 - p of the light emitting layer of each sub-pixel sp and the corresponding opening K are marked. The first sub-pixel sp1 is used as an example of a special-shaped sub-pixel spx. Fig.26As shown, in the irregular sub-pixel spx, the graphic 42-p of the light-emitting layer is circular, and the center O1 of the graphic 42-p of the light-emitting layer does not coincide with the center O2 of the first opening K1. Among them, the graphic shape of the first opening K1 is the same as the outline shape of the irregular sub-pixel spx, and the center O2 of the first opening K1 is the center of gravity of its graphic shape. In other embodiments, the graphic 42-p of the light-emitting layer is rectangular, which is not illustrated here. When the display panel is manufactured, the light-emitting layer 42 is manufactured by an evaporation process. The light-emitting layer 42 will be deposited in the opening K and extend to the outside. The hollow shape of the mask in the evaporation process is the same as the graphic shape of the light-emitting layer. In an embodiment of the present invention, the center O1 of the graphic 42-p of the light-emitting layer of the irregular sub-pixel spz does not coincide with the center O2 of the first opening K1, so it is not necessary to change the shape of the mask according to the shape of the irregular sub-pixel spz during evaporation.

[0129] In some embodiments, Fig. 27 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig. 27 As shown, the display panel includes a substrate 00, a light-blocking structure 50 and a reflection control layer 70; the light-blocking structure 50 is located on the side of the sub-pixel sp away from the substrate 00; the light-blocking structure 50 includes a plurality of hollows V. Along the direction e perpendicular to the plane where the substrate 00 is located, the hollows V overlap at least partially with the sub-pixel sp. The reflection control layer 70 is located on the side of the light-blocking structure 50 away from the substrate 00, and is at least partially located in the hollows V. The reflection control layer 70 is a whole layer, or the reflection control layer 70 overlapping with the sub-pixels sp of different colors is interconnected as a whole. The reflection control layer 70 is an anti-reflection layer, which has the function of reducing the reflection of the display panel to the ambient light. The reflection control layer 70 can selectively absorb some bands of light in the ambient light directed to the display panel or absorb some bands of light reflected from the inside of the display panel. For example, the sub-pixel sp includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel, and the reflection control layer 70 can absorb light in a wavelength band that deviates from the emission wavelength range of the red sub-pixel, the green sub-pixel, and the blue sub-pixel, thereby reducing the reflection of the display panel to ambient light while avoiding a reduction in display brightness. The material of the reflection control layer 70 includes dyes and pigments.

[0130] In some embodiments, the display panel further includes a support column, the orthographic projection of the support column on the substrate is located between the orthographic projection of the first sub-pixel sp1 on the substrate and the orthographic projection of the second sub-pixel sp2 on the substrate. The support column is used to support the mask in the evaporation process to ensure the uniformity of evaporation and improve the yield of evaporation.

[0131] Fig.28 A schematic diagram of another display panel provided by an embodiment of the present invention. Fig.28Shown in the top view, it can be understood that in the top view, the support pillars coincide with their orthographic projections on the substrate, and each sub-pixel in the top view coincides with its orthographic projection on the substrate. As Fig.28 shown, taking the first sub-pixel sp1 as the special-shaped sub-pixel spx as an example. The support pillar 80 includes a first support pillar 81 and a second support pillar 82.

In the embodiment of the present invention, by setting L4 < L3, it can be achieved that the distance between the first light sensor 91 and the irregular sub-pixel spx is equal to the distance between the first light sensor 91 and the second sub-pixel sp2, and it can also be achieved that the distance between the second light sensor 92 and the irregular sub-pixel spx is equal to the distance between the second light sensor 92 and the second sub-pixel sp2. When an optical blocking structure is provided (such as Fig.13 or Fig. 27In the display surface of the optical sensor 90, a light-blocking structure is also required to be provided with corresponding hollowing for the optical sensor 90. In the embodiment of the present invention, the optical sensor 90 is basically provided in the middle of two sub-pixels, so as to avoid the setting of the optical sensor 90 affecting the aperture ratio of the sub-pixel, and also to make the hollowing size of the light-blocking structure corresponding to the optical sensor 90 large enough to ensure the optical performance of the optical sensor 90.
