[0047] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0048] Various modifications and changes can be made to the present application without departing from the spirit and scope of the present application. Accordingly, the present application is intended to embrace all modifications and changes that fall within the scope of the corresponding claims (technical solutions claimed to be protected), and their equivalents. It should be noted that the embodiments provided in the embodiments of the present application can be combined with each other without contradiction.

[0049] The terms used in the embodiments of the present application are only for the purpose of describing particular embodiments and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0050] The display panel provided by the embodiments of the present application 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 shape profile of the special-shaped sub-pixel is connected at the beginning and the end by a circular arc and an elliptical arc. Thus, the directly opposite distance between the special-shaped sub-pixel and the adjacent sub-pixel can be increased, thereby improving the sub-pixel stealing and improving the display effect of the display panel.

[0051] FIG. 1 is a schematic diagram of a display panel according to an embodiment of the present application, and FIG. 2 is a schematic diagram of a shaped sub-pixel according to an embodiment of the present application. As shown in FIG. 1, the display panel includes a plurality of sub-pixels sp, and each sub-pixel sp includes a first sub-pixel sp1, a second sub-pixel sp2 and a third sub-pixel sp3 having different colors. The first sub-pixel sp1, the second sub-pixel sp2 and the third sub-pixel sp3 are 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 form a first virtual quadrilateral 10, the two first sub-pixels sp1 are located at a pair of opposite corners of the first virtual quadrilateral 10, the two second sub-pixels sp2 are located at another pair of opposite corners of the first virtual quadrilateral 10, and one third sub-pixel sp3 is located in the first virtual quadrilateral 10. Four third sub-pixels sp3 form 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. At least one of the first sub-pixel sp1, the second sub-pixel sp2 and the third sub-pixel sp3 includes a shaped sub-pixel spx. The top corners of each virtual quadrilateral are the centers of the sub-pixels sp at the top corner positions. In the embodiment of the present application, the first virtual quadrilateral 10 can be an irregular quadrilateral, a parallelogram or a square, and the second virtual quadrilateral 20 can be a parallelogram or a square.

[0052] In FIG. 1, the first sub-pixel sp1 is a shaped sub-pixel spx, and the second sub-pixel sp2 and the third sub-pixel sp3 are circular. In combination with FIG. 2, the shape profile of the 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 a first intersection point W1 and a second intersection point W2. The length of the circular arc l1 can be half of the circumference of the circle in which the circular arc l1 is located, i.e., the circular arc l1 is a semicircular arc, or the length of the circular arc l1 can be less than or greater than half of the circumference of the circle in which the circular arc l1 is located. The length of the elliptical arc l2 can be half of the circumference of the ellipse in which the elliptical arc l2 is located, i.e., the elliptical arc l2 is a semicircular arc, or the length of the elliptical arc l2 can be less than or greater than half of the circumference of the ellipse in which the elliptical arc l2 is located.

[0053] FIG. 3 is a schematic diagram of a display panel according to the related art, and each sub-pixel in FIG. 3 is taken as an example of a rectangle, and the shape of each sub-pixel can also be a circle. As shown in FIG. 3, two first sub-pixels sp1 and two second sub-pixels sp2 form a first virtual square 01, the two first sub-pixels sp1 are located at a pair of opposite corners of the first virtual square 01, the two second sub-pixels sp2 are located at another pair of opposite corners 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 form a second virtual square 02.

[0054] FIG. 4 is a schematic diagram of another display panel in the related art. As shown in FIG. 4, two first sub-pixels sp1 and two second sub-pixels sp2 form a first virtual trapezoid 01, the two first sub-pixels sp1 are located at a pair of diagonal positions of the first virtual trapezoid 03, the two second sub-pixels sp2 are located at another pair of diagonal positions 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 form a second virtual trapezoid 04. The pixel arrangement of FIG. 4 is equivalent to that obtained by deforming the pixel arrangement of FIG. 3. On the basis of the pixel arrangement shown in FIG. 3, the first virtual trapezoid 01 and the second virtual trapezoid 02 are formed by adjusting the positions of the sub-pixels, that is, the positions of the sub-pixels are moved to construct virtual quadrilaterals of different shapes. As shown in FIG. 4, the distance between the first sub-pixel sp1 and the second sub-pixel sp2 at the bottom of the first virtual trapezoid 01 is small, and there may be a problem of sub-pixel light stealing.

[0055] In the embodiments of the present application, at least one of the three sub-pixels is an irregular sub-pixel spx, the shape profile of the irregular sub-pixel spx is composed of a circular arc l1 and an elliptical arc l2, and the center position of the irregular sub-pixel spx varies according to its shape. The center position of the irregular sub-pixel spx can be adjusted by designing the shape of the irregular sub-pixel spx, and then the virtual quadrilateral in which the irregular sub-pixel spx is located can be of different shapes without moving the positions of the sub-pixels to meet the shape requirements of the virtual quadrilateral. The design of the irregular sub-pixel spx can make the distance between each irregular sub-pixel spx and the adjacent sub-pixel in the virtual quadrilateral in which the irregular sub-pixel spx is located relatively average, and the difference in the distance between each irregular sub-pixel spx and the adjacent sub-pixel is small, thereby improving the problem of sub-pixel light stealing. Moreover, in the embodiments of the present application, the irregular sub-pixel spx is composed of a circular arc l1 and an elliptical arc l2, and the light-emitting boundary thereof is relatively smooth and has no straight edge, which can be beneficial to reducing diffraction.

[0056] In addition, in some embodiments, the area size of the irregular sub-pixel spx can be greater than the area size of the virtual circle in which the circular arc l1 is located, which can increase the aperture ratio of the sub-pixel and improve the service life of the sub-pixel.

[0057] In some embodiments, FIG. 5 is a schematic diagram of another irregular sub-pixel provided by the embodiments of the present application. As shown in FIG. 5, the ellipse in which the elliptical arc l2 is located is a virtual ellipse 001, and the circle in which the circular arc l1 is located is a virtual circle 002; the virtual ellipse 001 has a major axis z1 and a minor axis z2. The circular arc l1 intersects the major axis z1 of the virtual ellipse 001. This embodiment can provide an irregular sub-pixel spx with a relatively large area size, for example, the area of the virtual ellipse 001 can be designed to be greater than the area of the virtual circle 002 in which the circular arc l1 is located, and the area size of the irregular sub-pixel spx can be greater than the area of the virtual circle 002 in which the circular arc l1 is located, which can increase the aperture ratio of the sub-pixel and improve the service life of the sub-pixel.

[0058] FIG. 6 is a schematic view of another shaped sub-pixel according to an embodiment of the present application. As shown in FIG. 6, the ellipse on which the elliptical arc l2 is located is a virtual ellipse 001, and the circle on which the circular arc l1 is located is a virtual circle 002. The virtual ellipse 001 has a short axis z2. The circular arc l1 intersects the extension of the short axis z2 of the virtual ellipse 001. This embodiment can provide a relatively small area size of the shaped sub-pixel spx. For example, 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 shaped sub-pixel spx can be smaller than the area of the virtual circle 002 on which the circular arc l1 is located. In the case of limited area space in the display panel, reducing the size of the shaped sub-pixel spx can correspondingly increase the size of the sub-pixels of other colors, increase the aperture ratio of the sub-pixels of other colors, and balance the life difference of the sub-pixels of different colors.

[0059] As shown in FIG. 5, the diameter R of the virtual circle 002 is the short axis z2 of the virtual ellipse 001. That is, the virtual circle 002 is an inscribed circle of the virtual ellipse 001. In this embodiment, the area size of the shaped 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 shaped sub-pixel spz is relatively smooth, which can reduce diffraction in application and improve display effect.

[0060] As shown in FIG. 6, the diameter R of the virtual circle 002 is the long 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 shaped sub-pixel spz composed of the circular arc l1 and the elliptical arc l2 is relatively small, which can leave more space for the sub-pixels of other colors in the entire display area, increase the size of the sub-pixels of other colors, and balance the life difference of the sub-pixels of different colors. Moreover, the connection transition between the circular arc l1 and the elliptical arc l2 is smooth, so that the boundary of the shaped sub-pixel spz is relatively smooth, which can reduce diffraction in application and improve display effect.

[0061] In some embodiments, FIG. 7 is a schematic view of another shaped sub-pixel according to an embodiment of the present application. As shown in FIG. 7, the ellipse on which the elliptical arc l2 is located is a virtual ellipse 001, and the circle on which the circular arc l1 is located is a virtual circle 002. The virtual ellipse 001 has a long axis z1 and a short axis z2. The circular arc l1 intersects the long axis z1 of the virtual ellipse 001, and the line segment connecting the first intersection point W1 and the second intersection point W1 is a first virtual line segment X1. The length of the first virtual line segment X1 is smaller than the length of the diameter R of the virtual circle 002. In this embodiment, the length of the circular arc l1 is smaller than half the circumference of the virtual circle 002 on which the circular arc l1 is located. The area of the region surrounded by the first virtual line segment X1 and the circular arc l1 is smaller than half the area of the virtual circle 002.

[0062] Optionally, as shown in FIG. 7, the first virtual line segment X1 coincides with the minor axis z2, and the length of the elliptical arc l2 is half the circumference of the virtual ellipse 001, and the elliptical arc l2 is a semicircular arc. The area of the region enclosed by the first virtual line segment X1 and the elliptical arc l2 is equal to half the area of the virtual ellipse 001.

[0063] In some other embodiments, FIG. 8 is a schematic diagram of another special-shaped sub-pixel provided by an embodiment of the present application. As shown in FIG. 8, the ellipse in which the elliptical arc l2 is located is a virtual ellipse 001, and the circle in which the circular arc l1 is located is a virtual circle 002; the virtual ellipse 001 has a major axis z1 and a minor axis z2. In this embodiment, the circular arc l1 intersects the major axis z1 of the virtual ellipse 001, and the line segment connecting 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 the circumference of the virtual ellipse 001 in which the elliptical arc l2 is located. The area of the region enclosed by the first virtual line segment X1 and the elliptical arc l2 is less than half the area of the virtual ellipse 001.

[0064] In some other embodiments, FIG. 9 is a schematic diagram of another special-shaped sub-pixel provided by an embodiment of the present application. As shown in FIG. 9, the ellipse in which the elliptical arc l2 is located is a virtual ellipse 001, and the circle in which the circular arc l1 is located is a virtual circle 002; the virtual ellipse 001 has a major axis z1 and a minor axis z2. In this embodiment, the circular arc l1 intersects the minor axis z2 of the virtual ellipse 001, and the line segment connecting 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 the circumference of the virtual ellipse 001 in which the elliptical arc l2 is located. The area of the region enclosed by the first virtual line segment X1 and the elliptical arc l2 is less than half the area of the virtual ellipse 001.

[0065] In some embodiments, as shown in FIGS. 5 and 6, the ellipse in which the elliptical arc l2 is located is a virtual ellipse 001, and the circle in which the circular arc l1 is located is a virtual circle 002; the line segment 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 segment 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.

[0066] As also shown in FIG. 9, the line segment 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. In the embodiment of FIG. 9, 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.

[0067] In some embodiments, FIG. 10 is another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present application. As shown in FIG. 10, the circle in which the circular arc l1 is located is a virtual circle 002; the two intersection points of the circular arc l1 and the elliptical arc l2 are a first intersection point W1 and a second intersection point W2; the line connecting the first intersection point W1 and the center O of the virtual circle 002 is a first line 1-1; the line connecting the second intersection point W2 and the center O of the virtual circle 002 is a second line 1-2; and the included 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, so that the length of the line connecting the first intersection point W1 and the second intersection point W2 is equal to the diameter length of the virtual circle 002. The area of the region surrounded by the line connecting the first intersection point W1 and the second intersection point W2 and the circular arc l1 in the special-shaped sub-pixel spz is half of the area of the virtual circle 002.

[0068] In some embodiments, FIG. 11 is another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present application. As shown in FIG. 11, the ellipse in which the elliptical arc l2 is located is a virtual ellipse 001; the two intersection points of the circular arc l1 and the elliptical arc l2 are a first intersection point W1 and a second intersection point W2; the line connecting the first intersection point W1 and the second intersection point W2 is a 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 special-shaped sub-pixel spz provided by this embodiment is symmetrical about the major axis z1, the shape profile of the special-shaped sub-pixel spz is an axisymmetric graph, and the shape of the special-shaped sub-pixel spz is relatively more regular. When the sub-pixels are arranged in the whole display panel, the special-shaped sub-pixel spz is more easily matched with other color sub-pixels, so that the sub-pixel arrangement is more uniform and compact. When the display is performed in the sub-pixel rendering mode, the display effect of the special-shaped sub-pixel spz matched with other sub-pixels is also better.

[0069] In an 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 in which the circular arc l1 is located. In this embodiment, the area of the region surrounded by the first virtual line segment X1 and the elliptical arc l2 is half of the area of the virtual ellipse 001, the area of the region surrounded by the first virtual line segment X1 and the circular arc l1 is half of the area of the virtual circle, the area size of the special-shaped sub-pixel spz is greater than the area of the virtual circle in which the circular arc l1 is located, and a special-shaped sub-pixel spz with a large area size can be obtained.

[0070] As shown in FIG. 11, the maximum distance of the circular arc l1 to the first virtual line segment X1 is a1, the maximum distance of the elliptical arc l2 to the first virtual line segment X1 is a2, and a1 < a2 ≤ 3 * a1. The special-shaped sub-pixel spz is composed of a part of an ellipse and a part of a circle, and the ellipse part and the circle part are divided by the first virtual line segment X1. a1 < a2 is set, so that the length of the ellipse part along the extension direction of the major axis z1 is greater than the length of the circle part. When a1 is the radius of the virtual circle where the circular arc l1 is located, the area of the special-shaped sub-pixel spz is greater than the area of the virtual circle where the circular arc l1 is located. Compared with the circular sub-pixel, the size of the special-shaped sub-pixel spz is larger, and the sub-pixel aperture ratio can be improved. a2 ≤ 3 * a1 is set, so that the difference between the length of the ellipse part and the length of the circle part along the extension direction of the major axis z1 is not too large, and the overall length of the special-shaped sub-pixel spz is not too long. When the area of the special-shaped sub-pixel spz meets the design requirement, it is easier to arrange the special-shaped sub-pixel spz with other sub-pixels, and the space utilization of the display panel can be higher.

[0071] In some embodiments, 1.1 ≤ a2:a1 ≤ 1.5.

[0072] In some embodiments, FIG. 12 is another schematic diagram of a special-shaped sub-pixel provided by an embodiment of the present application. As shown in FIG. 12, the ellipse where the elliptical arc l2 is located is a virtual ellipse 001, the two intersection points of the circular arc l1 and the elliptical arc l2 are a first intersection point W1 and a second intersection point W2, the line connecting the first intersection point W1 and the second intersection point W2 is a 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 special-shaped sub-pixel spz provided by this embodiment is symmetrical about the minor axis z2, the shape profile of the special-shaped sub-pixel spz is an axisymmetric graph, and the shape of the special-shaped sub-pixel spz is relatively more regular. When the sub-pixels are arranged in the whole surface of the display panel, the special-shaped sub-pixel spz is easier to cooperate with sub-pixels of other colors, so that the sub-pixel arrangement is more uniform and compact. When the display is performed in the sub-pixel rendering mode, the display effect of the special-shaped sub-pixel spz cooperating with other sub-pixels is also better.

[0073] 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 circular arc l1 is located. In this embodiment, the area of the region surrounded by the first virtual line segment X1 and the elliptical arc l2 is half of the area of the virtual ellipse 001, the area of the region surrounded by the first virtual line segment X1 and the circular arc l1 is half of the area of the virtual circle, and the area of the special-shaped sub-pixel spz is greater than the area of the virtual ellipse 001.

The special-shaped sub-pixel spz is composed of a part of an ellipse and a part of a circle, and the ellipse part and the circle part are divided by the first virtual line segment X1. By setting c1 to be less than c2, the length of the circle part in the extension direction of the short axis z2 is greater than the length of the ellipse part. When c2 is the radius of the virtual circle where the circular arc l1 is located, the area of the special-shaped sub-pixel spz can be greater than the area of the virtual ellipse 001 and less than the area of the virtual circle where the circular arc l1 is located. By setting c1 / c2 to satisfy a certain range, the shape of the special-shaped sub-pixel spz will not be too flat, and the area of the special-shaped sub-pixel spz will not be too small, which can ensure the reasonable use of the overall space of the display panel.

[0081] In some embodiments, the first sub-pixel sp1 or the second sub-pixel sp2 is a shaped sub-pixel spz. In some embodiments, the third sub-pixel sp3 is a shaped sub-pixel spz. In some embodiments, the first sub-pixel sp1 (or the second sub-pixel sp2) is partially a shaped sub-pixel spz and partially a regular sub-pixel (such as a circular or rectangular sub-pixel). According to the sub-pixel arrangement shown in FIG. 1, 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. Hereinafter, the first sub-pixel sp1 is taken as an example of a shaped sub-pixel spz, and the case where the second sub-pixel sp2 is a shaped sub-pixel spz can be understood by analogy.

[0082] In the embodiment of the present application, when the sub-pixels constitute a virtual figure, the center of the sub-pixel is taken as the vertex of the virtual figure. For a circular sub-pixel, the center of the sub-pixel is taken as the center of the circular sub-pixel, and for a shaped sub-pixel spz, the center of gravity of the outline figure of the shaped sub-pixel spz is taken as the center. FIG. 17 is a schematic diagram of the center position of a shaped sub-pixel in the embodiment of the present application. As shown in FIG. 17, the ellipse on which the arc l2 is located is a virtual ellipse 001, and the circle on which the arc l1 is located is a virtual circle 002; the virtual ellipse 001 has a major axis z1 and a minor axis z2.

[0083] In some embodiments, FIG. 18 is a schematic diagram of another display panel provided by the embodiment of the present application. As shown in FIG. 18, 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 the second virtual quadrilateral 20 has one first sub-pixel sp1 therein; wherein the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all shaped sub-pixels spx. The direction of the arc l1 pointing to the arc l2 in the shaped sub-pixel spx is the direction of the arc l2. In the third virtual quadrilateral 30, the directions of the arcs l2 of the two first sub-pixels sp1 located at opposite corners are perpendicular to each other.

[0084] In some other embodiments, FIG. 19 is a schematic diagram of another display panel provided by the embodiment of the present application. As shown in FIG. 19, 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 the second virtual quadrilateral 20 has one first sub-pixel sp1 therein; wherein the four first sub-pixels sp1 constituting the third virtual quadrilateral 30 are all shaped sub-pixels spx. In the third virtual quadrilateral 30, the directions of the arcs l2 of the two first sub-pixels sp1 located at opposite corners are parallel to each other. Optionally, as shown in FIG. 19, the directions of the arcs l2 of the two first sub-pixels sp1 located at opposite corners are the same.

[0085] In the embodiment of the present application, four first sub-pixels sp1 are arranged to form the third virtual quadrilateral 30. One first sub-pixel sp1 is arranged in one third virtual quadrilateral 30. The four first sub-pixels sp1 forming the third virtual quadrilateral 30 are special-shaped sub-pixels spz. Since the shape profile of the special-shaped sub-pixel spz is formed by the circular arc l1 and the elliptical arc l2, the center position of the special-shaped sub-pixel spz is affected by the orientation of the elliptical arc. The orientations of the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions in the third virtual quadrilateral 30 are perpendicular to each other or parallel to each other, so that different shapes of the third virtual quadrilateral 30 can be formed. The third virtual quadrilateral 30 can be a parallelogram, an irregular quadrilateral or a trapezoid. By designing the shape of the special-shaped sub-pixel spx, the virtual quadrilateral in which the special-shaped sub-pixel spx is located can have different shapes, without the need to move the position of the sub-pixel to meet the shape requirement of the virtual quadrilateral. The design of the special-shaped sub-pixel spx can make the distance between each special-shaped sub-pixel spx and the adjacent sub-pixel in the virtual quadrilateral in which the special-shaped sub-pixel spx is located relatively uniform, so that the problem of sub-pixel light stealing can be improved. In addition, the orientations of the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions in the third virtual quadrilateral 30 are perpendicular to each other or parallel to each other, so that the first sub-pixels sp1 on the entire display panel have different orientations of the elliptical arcs, which is beneficial to improve the display viewing angle and can improve the large viewing angle display effect.

[0086] In addition, in FIGS. 18 and 19, the first sub-pixel sp1 in the third virtual quadrilateral 30 is also a special-shaped sub-pixel spx, that is, the first sub-pixel sp1 is a special-shaped sub-pixel spx. In some embodiments, the first sub-pixel sp1 in the third virtual quadrilateral 30 is a regular-shaped sub-pixel, that is, part of the first sub-pixel sp1 is a special-shaped sub-pixel spx and part of the first sub-pixel sp1 is a regular sub-pixel, which will be illustrated in the related embodiments below.

[0087] In some embodiments, as shown in FIG. 18 or FIG. 19, four first sub-pixels sp1 constitute a third virtual quadrangle 30; one second virtual quadrangle 20 is located in the third virtual quadrangle 30, and there is one first sub-pixel sp1 in the second virtual quadrangle 20; wherein the four first sub-pixels sp1 constituting the third virtual quadrangle 30 are all special-shaped sub-pixels spx. There are four first virtual quadrangles 10 at the position of the third virtual quadrangle 30; among the four first virtual quadrangles 10, the distance between the center of the second sub-pixel sp2 and the center of the third sub-pixel sp3 is equal. When designing the arrangement of sub-pixels, the distance between the first sub-pixel sp1 and the second sub-pixel sp2 can be fine-tuned by adjusting the orientation of the elliptical arc of the first sub-pixel sp1, while the distance between the second sub-pixel sp2 and the third sub-pixel sp3 remains unchanged, so that the distance between each first sub-pixel sp1 and the second sub-pixel sp2 is relatively average. As can be provided, the fourth virtual quadrangle 40 constituted by the second sub-pixel sp2 is a square, and there is one second virtual quadrangle 20 in the fourth virtual quadrangle 40.

[0088] As shown in FIG. 18, on the third virtual quadrangle 30, the orientations of the elliptical arcs of two first sub-pixels sp1 adjacent along the first direction x are different, and the orientations of the elliptical arcs of two first sub-pixels sp1 adjacent along the second direction y are the same. The first direction x and the second direction y intersect each other. As shown in FIG. 19, on the third virtual quadrangle 30, the orientations of the elliptical arcs of two first sub-pixels sp1 adjacent along the first direction x are different, and the orientations of the elliptical arcs of two first sub-pixels sp1 adjacent along the second direction y are different. The embodiments of FIG. 18 and FIG. 19 respectively design the orientations of the elliptical arcs of the first sub-pixels sp1 at the opposite corners of the third virtual quadrangle 30 and the orientations of the elliptical arcs of the first sub-pixels sp1 adjacent along the first direction x / adjacent along the second direction y, which can respectively constitute third virtual quadrangles 30 of different shapes. That is, by designing the shape of the special-shaped sub-pixel spx, the virtual quadrangle in which it is located can be of different shapes, without the need to move the position of the sub-pixel to meet the shape requirement of the virtual quadrangle. In addition, arranging a plurality of first sub-pixels sp1 on the entire display panel to have different orientations of elliptical arcs is beneficial to improving the display visual role bias and can improve the large-angle display effect.

[0089] In the display panel, data lines and scan lines are arranged, and the pixel circuit is connected with 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 lines extend along the first direction x, and the data lines extend along the second direction y; or the data lines extend along the first direction x, and the scan lines extend 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 herein.

[0090] In one embodiment, the third virtual quadrilateral 30 in the embodiment of FIG. 18 is a parallelogram.

[0091] In one embodiment, the third virtual quadrilateral 30 in the embodiment of FIG. 19 is an irregular quadrilateral.

[0092] In another embodiment, FIG. 20 is a schematic view of another display panel according to an embodiment of the present application. As shown in FIG. 20, four first sub-pixels sp1 form a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and the second virtual quadrilateral 20 has one first sub-pixel sp1 therein; wherein the four first sub-pixels sp1 forming the third virtual quadrilateral 30 are all special-shaped sub-pixels spx. In the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions are oriented in the same direction. In the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 adjacent in the first direction x are oriented in different directions, and the elliptical arcs of the two first sub-pixels sp1 adjacent in the second direction y are oriented in opposite directions. The third virtual quadrilateral 30 in this embodiment is a trapezoid.

[0093] In some embodiments, four first sub-pixels sp1 form a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and the second virtual quadrilateral 20 has one first sub-pixel sp1 therein; wherein the four first sub-pixels sp1 forming the third virtual quadrilateral 30 are all special-shaped sub-pixels spx. As shown in FIG. 18, in the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions are oriented perpendicular to each other. As shown in FIG. 19, in the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions are oriented parallel to each other. In FIGS. 18 and 19, the elliptical arcs of the first sub-pixels sp1 located on the third virtual quadrilateral 30 have an acute angle with the first direction x. Optionally, the acute angle is 45°. In FIG. 20, in the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions are oriented parallel to each other, and the elliptical arcs of the first sub-pixels sp1 located on the third virtual quadrilateral 30 are oriented parallel or perpendicular to the first direction x.

[0094] In the positive placement of the first sub-pixel sp1 with the circular arc l1 at the lower side and the elliptical arc l2 at the upper side as an example, the first sub-pixel sp1 located on the third virtual quadrilateral 30 is inclined relative to the first direction x in FIGS. 18 and 19. When the first direction x and the second direction y are perpendicular to each other, it is also equivalent to that the special-shaped sub-pixel spz is inclined relative to the second direction y. The special-shaped sub-pixel spz is placed in the positive or inverted manner in the embodiment of FIG. 20. The placement manner of the special-shaped sub-pixel spz is designed in the embodiment of the present application, so that the first virtual quadrilateral 10 formed by the special-shaped first sub-pixel sp1 and the second sub-pixel sp2 can be deformed more. For example, the first virtual quadrilateral 10 can be a parallelogram or an irregular quadrilateral, so as to balance the distance difference between the first sub-pixel sp1 and the other color sub-pixels, make the distance relatively average, and improve the problem of sub-pixel stealing. In addition, the display panel is provided with a plurality of first sub-pixels sp1 with different elliptical arc orientations, which is beneficial to improve the display visual role deviation and improve the large viewing angle display effect.

[0095] In some embodiments, as shown in FIGS. 18, 19 or 20, four first sub-pixels sp1 form a third virtual quadrilateral 30; a second virtual quadrilateral 20 is located in the third virtual quadrilateral 30, and the second virtual quadrilateral 20 has one first sub-pixel sp1; wherein the four first sub-pixels sp1 forming the third virtual quadrilateral 30 are special-shaped sub-pixels spx. The first sub-pixel sp1 in the third virtual quadrilateral 30 is a special-shaped sub-pixel spx, and the elliptical arc orientation of the first sub-pixel sp1 is different from that 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 special-shaped sub-pixels spx, and the elliptical arc orientations of the special-shaped sub-pixels spx are various, so that the elliptical arc orientations of adjacent special-shaped sub-pixels spx are different. The first sub-pixels sp1 are more uniformly distributed in the entire display area of the display panel, and the display effects of the pixels in which the first sub-pixels sp1 participate are less different when the display panel is displayed in the sub-pixel rendering mode, and the overall display effect is better.

[0096] As shown in FIG. 18, FIG. 19 or FIG. 20, the elliptical arc direction of the first sub-pixel sp1 located in the third virtual quadrilateral 30 is perpendicular to the elliptical arc direction of at least one of the four first sub-pixels sp1 constituting the third virtual quadrilateral 30. Such arrangement can enable 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. The display panel provided in this embodiment has small differences in display effects of each pixel in which the first sub-pixel sp1 participates when the display panel is displayed in the sub-pixel rendering mode, and the overall display effect is better. In addition, arranging the first sub-pixels sp1 on the entire display panel to have different elliptical arc directions is beneficial to improving display visual character bias and can improve large-angle display effect.

[0097] In some embodiments, as shown in FIG. 18 and FIG. 19, the elliptical arc direction of the first sub-pixel sp1 located in the third virtual quadrilateral 30 has an acute angle with the first direction x; the third virtual quadrilateral 30 has four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30; and 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 arranging the elliptical arc direction of the first sub-pixel sp1, the distance difference between the first sub-pixel sp1 and the second sub-pixel sp2 in the first sub-virtual quadrilateral 11 can be balanced, and the problem of light stealing caused by too small distance between the first sub-pixel sp1 and the second sub-pixel sp2 can be improved.

[0098] As shown in FIG. 18 and FIG. 19, in the first sub-virtual quadrilateral 11, the distance between the center of one first sub-pixel sp1 and the center of the third sub-pixel sp3 is d1, the distance between the center of the other first sub-pixel sp1 and the center of the third sub-pixel sp3 is d2, and the distance between the center of each second sub-pixel sp2 and the center of the third sub-pixel sp3 is d3; wherein d1>d3>d2. In this embodiment, since the elliptical arc directions of the first sub-pixels sp1 at the opposite corners of the first sub-virtual quadrilateral 11 are perpendicular to each other, the first sub-virtual quadrilateral 11 can form an irregular quadrilateral, and the distances between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 in the first sub-virtual quadrilateral 11 can be relatively average, which is beneficial to improving the problem of sub-pixel light stealing.

[0099] In some embodiments, as shown in FIG. 18, the first sub-pixel sp1 is a special-shaped sub-pixel spz, the four third sub-pixels sp3 constitute the second virtual quadrilateral 20 as a square, the four second sub-pixels sp2 constitute the fourth virtual quadrilateral 40 as a square, and the fourth virtual quadrilateral 40 has one second virtual quadrilateral 20 inside. Among them, 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. Since the four third sub-pixels sp3 constitute the second virtual quadrilateral 20 as a square, the green sub-pixels can be located on the same straight line in the row direction and on the same straight line in the column direction, and the green sub-pixels are relatively evenly distributed in the row direction and the column direction. When displaying by using the sub-pixel rendering method, the display effect of the horizontal and vertical straight lines will be better. In addition, the four second sub-pixels sp2 constitute the fourth virtual quadrilateral 40 as a square, so that the second sub-pixels sp2 are located on the same straight line in the row direction and on the same straight line in the column direction, and are relatively evenly distributed in the row direction and the column direction. On this basis, by adjusting the elliptical arc direction of the special-shaped sub-pixel spz, the first virtual quadrilateral 10 can have different shapes, thereby more easily realizing that the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 is relatively average, and achieving the technical effect of improving the sub-pixel stealing light.

[0100] As shown in FIG. 18, the elliptical arc directions of the two first sub-pixels sp1 adjacent in the second direction y on the third virtual quadrilateral 30 are the same. The first virtual quadrilateral 10 further includes a second virtual quadrilateral 12. In the second virtual quadrilateral 12, the distance between the centers of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 is equal, and the distance between the centers of the two second sub-pixels sp2 and the center of the third sub-pixel sp3 is equal. The second 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 average, which is beneficial to improve the problem of sub-pixel stealing light.

[0101] In some embodiments, as shown in FIG. 18, there are two first sub-virtual quadrilaterals 11 and two second sub-virtual quadrilaterals 12 at the position 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. In the embodiment of FIG. 18, 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 top corner of the third virtual quadrilateral 30. Thus, two first sub-virtual quadrilaterals 11 and two second sub-virtual quadrilaterals 12 of different sizes are formed at the position 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 d1; in the other 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 d4, d4>d1. In the embodiment of the application, 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 of different sizes can be formed at the position of the third virtual quadrilateral 30. By matching, the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 can be relatively average, which is beneficial to improve the problem of sub-pixel stealing.

[0102] As shown in FIG. 18, in the two second sub-virtual quadrilaterals 12 at the position of the third virtual quadrilateral 30, the elliptical arc directions of the two first sub-pixels sp1 located at the opposite corners of the second sub-virtual quadrilateral 12 are opposite, and the second sub-virtual quadrilateral 12 can form a parallelogram.

[0103] In some embodiments, as shown in FIG. 18, the first sub-pixel sp1 is a special-shaped sub-pixel spz, and four first sub-pixels sp1 constitute 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 position of the third virtual quadrilateral 30: two first virtual quadrilaterals 10 are irregular quadrilaterals, and the other two first virtual quadrilaterals 10 are parallelograms. The first sub-virtual quadrilateral 11 and the second sub-virtual quadrilateral 12 are neither trapezoids, which can make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively average, and is conducive to improving the problem of sub-pixel stealing. In the scheme in which 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 arranged to constitute a second virtual quadrilateral 20 which is a square, which can make the green sub-pixels be located on the same straight line in the row direction and on the same straight line in the column direction, and the green sub-pixels are relatively evenly distributed in the row direction and the column direction, and the display effect of horizontal and vertical straight lines will be better when the sub-pixel rendering method is used for display. In addition, the fourth virtual quadrilateral 40 constituted by the four second sub-pixels sp2 is a square, and the fourth virtual quadrilateral 40 has one second virtual quadrilateral 20, the second sub-pixels sp2 are located on the same straight line in the row direction and on the same straight line in the column direction, and the second sub-pixels sp2 are relatively evenly distributed in the row direction and the column direction. On this basis, by adjusting the direction of the elliptical arc of the special-shaped sub-pixel spz, the first virtual quadrilateral 10 can have different shapes, thereby more easily achieving the relative average of the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2, and achieving the technical effect of improving the sub-pixel stealing.

[0104] In some embodiments, as shown in FIG. 19, the elliptical arc directions of two first sub-pixels sp1 adjacent in the second direction y direction 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 top corner of the third virtual quadrilateral 30. The first virtual quadrilateral 10 further includes a third sub-virtual quadrilateral 13, in which the distance between the center of one first sub-pixel sp1 and the center of the third sub-pixel sp3 is d1, the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is d5, d5>d1, and the distance between the center of two second sub-pixels sp2 and the center of the third sub-pixel sp3 is equal. In this embodiment, by setting the elliptical arc direction of the first sub-pixel sp1 at the opposite corners of the third sub-virtual quadrilateral 13, the third sub-virtual quadrilateral 13 can form 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 average, which is beneficial to improve the problem of sub-pixel stealing.

[0105] In some embodiments, as shown in FIG. 19, the first sub-pixel sp1 is a special-shaped sub-pixel spz, the four third sub-pixels sp3 form a second virtual quadrilateral 20 which is a square, and the four second sub-pixels sp2 form a fourth virtual quadrilateral 40 which is a square, and the fourth virtual quadrilateral 40 has one second virtual quadrilateral 20. In the scheme in which 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, setting the four third sub-pixels sp3 to form a second virtual quadrilateral 20 which is a square can make the green sub-pixels be located on the same straight line in the row direction and on the same straight line in the column direction, and the green sub-pixels are relatively uniformly distributed in the row direction and the column direction. When sub-pixel rendering is used for display, the display effect of the straight line in the horizontal and vertical directions will be better. In addition, the four second sub-pixels sp2 form a fourth virtual quadrilateral 40 which is a square, so that the second sub-pixels sp2 are located on the same straight line in the row direction and on the same straight line in the column direction, and are relatively uniformly distributed in the row direction and the column direction. On this basis, by adjusting the elliptical arc direction of the special-shaped sub-pixel spz, the first virtual quadrilateral 10 can have different shapes, thereby more easily achieving the relative average of the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2, and achieving the technical effect of improving the sub-pixel stealing.

[0106] As shown in FIG. 19, at the position of the third virtual quadrilateral 30, two first sub virtual quadrilaterals 11 are adjacent and share a virtual edge in the first direction x, and two third sub virtual quadrilaterals 13 are adjacent and share a virtual edge in the first direction x. In the embodiment of the present application, the two first sub virtual quadrilaterals 11 and the two third sub virtual quadrilaterals 13 at the position of the third virtual quadrilateral 30 can be formed by setting the elliptic arc direction of the first sub-pixel sp1. By matching, the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 can be relatively average, which is beneficial to improve the problem of sub-pixel stealing.

[0107] As shown in FIG. 19, the first sub-pixel sp1 is a special-shaped sub-pixel spz, the fourth virtual quadrilateral 40 formed by four second sub-pixels sp2 is a square, and the fourth virtual quadrilateral 40 has one second virtual quadrilateral 20. The third virtual quadrilateral 30 is formed by four first sub-pixels sp1, and the third virtual quadrilateral 30 is a parallelogram. The second virtual quadrilateral 20 in the third virtual quadrilateral 30 is a square. The four first virtual quadrilaterals 10 at the position 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 average, and is beneficial to improve the problem of sub-pixel stealing.

[0108] In some embodiments, as shown in FIG. 20, the elliptical arcs of the first sub-pixels sp1 located on the third virtual quadrilateral 30 are parallel 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 along the second direction y on the third virtual quadrilateral 30 are opposite, and the first direction x and the second direction y intersect each other. In the first virtual quadrilateral 10, the distance between the center of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 is equal, the distance between the center of the two second sub-pixels sp2 and the center of the third sub-pixel sp3 is equal, 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 arcs of the first sub-pixels sp1 located in the third virtual quadrilateral 30 are perpendicular to the elliptical arcs of the first sub-pixels sp1 located at the top corner of the third virtual quadrilateral 30, which can make the first virtual quadrilateral 10 form an irregular quadrilateral and make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively average. In the first virtual quadrilateral 10, the distance between the center of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 is equal, and the distance between the center of the two second sub-pixels sp2 and the center of the third sub-pixel sp3 is equal. When displayed by using the sub-pixel rendering mode, the display effect of each pixel participated by the first sub-pixel sp1 is small, and the overall display effect is better.

[0109] As shown in FIG. 20, the distance between the center of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 in the first virtual quadrilateral 10 at the position of the third virtual quadrilateral 30 is equal to the distance between the center of the two second sub-pixels sp2 and 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 distance between the center of the first sub-pixel sp1 and the center of the third sub-pixel sp3 is d6; in the fifth sub-virtual quadrilateral 15, the distance between the center of the first sub-pixel sp1 and the center of the third sub-pixel sp3 is d7, d7>d6. At the position of the third virtual quadrilateral 30, the two fourth sub-virtual quadrilaterals are adjacent in the second direction and share a virtual edge, and the two fifth sub-virtual quadrilaterals are adjacent in the second direction and share a virtual edge. In this embodiment, by setting the elliptical arc direction of the first sub-pixel sp1 located in the third virtual quadrilateral 30 to be perpendicular to the elliptical arc direction of the first sub-pixel sp1 located at the top corner of the third virtual quadrilateral 30, two kinds of first virtual quadrilaterals 10 can be formed at the position of the third virtual quadrilateral 30, and the distance between the center of the first sub-pixel sp1 and the center of the third sub-pixel sp3 in the two kinds of first virtual quadrilaterals 10 is not equal. Such a design can make the arrangement of the three sub-pixels more compact, ensure the space utilization, and make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively average.

[0110] In some embodiments, as shown in FIG. 20, the first sub-pixel sp1 is a special-shaped sub-pixel spz, and the 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 position 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 average, and is beneficial to improve the problem of sub-pixel stealing. In the scheme in which 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, the four third sub-pixels sp3 are arranged to constitute a second virtual quadrilateral 20 which is a square, which can make the green sub-pixels be located on the same straight line in the row direction and on the same straight line in the column direction, and the green sub-pixels are relatively uniformly distributed in the row direction and the column direction, and the display effect of horizontal and vertical straight lines is better when the sub-pixel rendering method is used for display. In addition, the fourth virtual quadrilateral 40 constituted by the four second sub-pixels sp2 is a square, and the fourth virtual quadrilateral 40 has one second virtual quadrilateral 20, the second sub-pixels sp2 are located on the same straight line in the row direction and on the same straight line in the column direction, and the second sub-pixels sp2 are relatively uniformly distributed in the row direction and the column direction. On this basis, by adjusting the direction of the elliptical arc of the special-shaped sub-pixel spz, the first virtual quadrilateral 10 can have different shapes, thereby more easily achieving the relative average of the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2, and achieving the technical effect of improving the sub-pixel stealing.

[0111] In the embodiment of FIG. 20, 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 in the first direction x or on the same straight line in the second direction y, the four first virtual quadrilaterals 10 at the position of the third virtual quadrilateral 30 are irregular quadrilaterals with one right angle.

[0112] In some embodiments, FIG. 21 is a schematic view of another display panel provided by an embodiment of the present application. As shown in FIG. 21, four first sub-pixels sp1 form a third virtual quadrilateral 30. The first sub-pixels sp1 include first sub-pixels sp1-1 of a first type and second sub-pixels sp1-2 of a second type. The first sub-pixels sp1-1 of the first type are special-shaped sub-pixels spx, and the second sub-pixels sp1-2 of the second type are circular in shape. The first sub-pixels sp1 forming the third virtual quadrilateral 30 are the first sub-pixels sp1-1 of the first type, and the second sub-pixels sp1-2 of the second type are located in the third virtual quadrilateral. In this embodiment, one of the two first sub-pixels sp1 located at opposite corners of the first virtual quadrilateral 10 is a special-shaped sub-pixel spx, and the other is a regular sub-pixel. The design of the direction of the elliptical arc of the special-shaped sub-pixel spx can adjust the shape of the first virtual quadrilateral 10, so that the distance between the first sub-pixels sp1 and the second sub-pixels sp2 on the first virtual quadrilateral 10 is relatively uniform, and the problem of sub-pixel stealing can be improved.

[0113] In some embodiments, the area of the first sub-pixel sp1-1 of the first type is equal to the area of the second sub-pixel sp1-2 of the second type. The shape of the opening of the pixel definition layer corresponding to each of the two types of first sub-pixels sp1 is designed to make the areas of the two types of first sub-pixels sp1 equal. Such a design can make the contributions of the two types of first sub-pixels sp1 to the display when cooperating with other color sub-pixels substantially the same, and the overall display uniformity is better.

[0114] In some embodiments, as shown in FIG. 21, there are four first virtual quadrilaterals 10 at the positions of the third virtual quadrilateral 30. In the first virtual quadrilateral 10, the distance between the centers of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 is not equal, and the distance between the centers of the two second sub-pixels sp2 and the center of the third sub-pixel sp3 is equal. By setting one of the two first sub-pixels sp1 at the opposite corners of the first virtual quadrilateral 10 to be a special-shaped sub-pixel spx and the other to be a regular sub-pixel, the distance between the centers of the two first sub-pixels sp1 and the center of the third sub-pixel sp3 can be made not equal, which can adjust the shape of the first virtual quadrilateral 10, so that the distance between the first sub-pixels sp1 and the second sub-pixels sp2 on the first virtual quadrilateral 10 is relatively uniform. When the second virtual quadrilateral formed by the four third sub-pixels sp3 is a square and the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, the distance between the second sub-pixel sp1-2 of the second type and the four second sub-pixels sp2 around it is equal, and the first virtual quadrilateral 10 is an irregular quadrilateral, and the distance between the adjacent first sub-pixels sp1 and second sub-pixels sp2 at different positions is small.

[0115] As shown in FIG. 21, the elliptical arc of the first sub-pixel sp1 located on the third virtual quadrilateral 30 has an acute included angle with the first direction x; the first sub-pixel sp1 located in the third virtual quadrilateral 30 is circular. Among 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 one first sub-pixel sp1 and the center of the third sub-pixel sp3 is h1, and the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h2; in two first virtual quadrilaterals 10, the distance between the center of one first sub-pixel sp1 and the center of the third sub-pixel sp3 is h3, and the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h2, h1>h3; in one first virtual quadrilateral 10, the distance between the center of one first sub-pixel sp1 and the center of the third sub-pixel sp3 is h4, and the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h2; h3>h4. In this embodiment, the elliptical arcs of the first sub-pixels sp1 at the opposite corners of the third virtual quadrilateral 30 are arranged to have the same direction, and each first sub-pixel sp1 has an acute included angle between the elliptical arc direction and the first direction x, thereby forming three sizes of first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30. In fact, by adjusting the elliptical arc direction of the first sub-pixel sp1 at the corner of the third virtual quadrilateral 30, three sizes of first virtual quadrilaterals 10 are obtained, which can make the distance between the first sub-pixel sp1 and the second sub-pixel sp2 on the first virtual quadrilateral 10 relatively average, and is beneficial to improve the problem of sub-pixel stealing.

[0116] As shown in FIG. 21, part of the plurality of first sub-pixels sp1 are special-shaped sub-pixels spz, and part are circular sub-pixels; the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square, and the fourth virtual quadrilateral 40 formed by the four second sub-pixels sp2 is a square, and the fourth virtual quadrilateral 40 has one second virtual quadrilateral 20 inside. The first sub-pixel sp1 constituting the third virtual quadrilateral 30 is a special-shaped sub-pixel spz, and the first sub-pixel sp1 located in the third virtual quadrilateral 30 is a circular sub-pixel. 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 quadrilateral 10 is an irregular quadrilateral, which can make the distance between the first sub-pixel sp1 and the adjacent second sub-pixel sp2 relatively average in size, and is beneficial to improve the problem of sub-pixel stealing.

[0117] In some embodiments, FIG. 22 is a schematic view of another display panel according to the present application, as shown in FIG. 22, four first sub-pixels sp1 form a third virtual quadrilateral 30, the first sub-pixels sp1 include first sub-pixels sp1-1 of a first type and second sub-pixels sp1-2 of a second type, the first sub-pixels sp1-1 of the first type are shaped sub-pixels spx, and the second sub-pixels sp1-2 of the second type are circular in shape. The first sub-pixels sp1 forming the third virtual quadrilateral 30 are the first sub-pixels sp1-1 of the first type, and the second sub-pixels sp1-2 of the second type are located in the third virtual quadrilateral. The elliptical arcs of the first sub-pixels sp1 located on the third virtual quadrilateral 30 are parallel or perpendicular to the first direction x, and FIG. 22 shows the perpendicular direction. Among 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 one first sub-pixel sp1 and the center of a third sub-pixel sp3 is h5, and the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h6; in the other two first virtual quadrilaterals 10, the distance between the center of one first sub-pixel sp1 and the center of a third sub-pixel sp3 is h7, and the distance between the center of another first sub-pixel sp1 and the center of the third sub-pixel sp3 is h6, h5>h7. Optionally, h6>h7, or h6=h7. In this embodiment, the third virtual quadrilateral 30 is a trapezoid, and the four first virtual quadrilaterals 10 at the location of the third virtual quadrilateral 30 are irregular quadrilaterals. By adjusting the elliptical arc direction of the first sub-pixel sp1 at the top corner of the third virtual quadrilateral 30, two irregular first virtual quadrilaterals 10 are obtained, so that the distance between the first sub-pixel sp1 and the second sub-pixel sp2 on the first virtual quadrilateral 10 is relatively uniform, which is beneficial to improve the problem of sub-pixel stealing. In addition, the display panel is provided with a plurality of first sub-pixels sp1 having different elliptical arc directions, which is beneficial to improve the display viewing angle, and can improve the large viewing angle display effect.

[0118] In addition, in the embodiment of FIG. 22, the third virtual quadrilateral 30 is located at a position having four first virtual quadrilaterals 10; among 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 the fourth virtual quadrilateral 40 has one second virtual quadrilateral 20 inside. Among them, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square. In the scheme in which 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, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is set to be a square, which can make the green sub-pixels be located on the same straight line in the row direction and on the same straight line in the column direction, and the green sub-pixels are relatively evenly distributed in the row direction and the column direction. When the display is displayed in the sub-pixel rendering mode, the display effect of the horizontal and vertical straight lines will be better.

[0119] In the embodiment of FIG. 22, 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 in 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 angles. In some embodiments, FIG. 23 is another schematic diagram of a display panel provided by an embodiment of the present application, as shown in FIG. 23, the third virtual quadrilateral 30 is formed by four first sub-pixels sp1; one second virtual quadrilateral 20 is located inside the third virtual quadrilateral 30, and the second virtual quadrilateral 20 has one first sub-pixel sp1 inside. The display panel includes a fourth virtual quadrilateral 40, the fourth virtual quadrilateral 40 is formed by four second sub-pixels sp2; one second virtual quadrilateral 20 is located inside the fourth virtual quadrilateral 40, and the second virtual quadrilateral 20 has one second sub-pixel sp2 inside. Among them, the four first sub-pixels sp1 forming the third virtual quadrilateral 30 are all special sub-pixels spx, and the four second sub-pixels sp2 forming the fourth virtual quadrilateral 40 are all special sub-pixels spx. In the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at the opposite positions are perpendicular to each other. In the fourth virtual quadrilateral 40, the elliptical arcs of the two second sub-pixels sp2 located at the opposite positions are perpendicular to each other. In this embodiment, the first sub-pixel sp1 and the second sub-pixel sp2 are all set to be special sub-pixels spx, which can make the shape of the first virtual quadrilateral 10 more variable. By designing the elliptical arc direction of the special sub-pixel spx to fine-tune the distance between the first sub-pixel sp1 and the second sub-pixel sp2, the distance between the first sub-pixel sp1 and the second sub-pixel sp2 is relatively average, which can improve the problem of sub-pixel stealing.

[0120] In some embodiments, in the example of FIG. 23, the second virtual quadrilateral 20 formed by the four third sub-pixels sp3 is a square.

[0121] In another example, in the third virtual quadrilateral 30, the elliptical arcs of the two first sub-pixels sp1 located at the diagonal positions are directed towards each other; in the fourth virtual quadrilateral 40, the elliptical arcs of the two second sub-pixels sp2 located at the diagonal positions are directed towards each other. This is not shown in the figures.

[0122] In some embodiments, as shown in FIG. 23, in the third virtual quadrilateral 30, the elliptical arcs of two first sub-pixels sp1 adjacent along a first direction x are directed towards different directions, and the elliptical arcs of two first sub-pixels sp1 adjacent along a second direction y are directed towards different directions; the first direction intersects the second direction; and / or, in the fourth virtual quadrilateral 40, the elliptical arcs of two second sub-pixels sp2 adjacent along a first direction x are directed towards different directions, and the elliptical arcs of two second sub-pixels sp2 adjacent along a second direction y are directed towards different directions. Such arrangement can make the distances between the first sub-pixels sp1 and the second sub-pixels sp2 in the entire display area of the display panel relatively uniform, and can improve the problem of sub-pixel stealing. In addition, arranging the plurality of first sub-pixels sp1 in the entire display panel to have different elliptical arc directions is beneficial to improving the display viewing angle, and can improve the large viewing angle display effect.

[0123] In some embodiments, as shown in FIG. 23, the first sub-pixel sp1 in the third virtual quadrilateral 30 is a special-shaped sub-pixel spx, and the elliptical arc direction of the first sub-pixel sp1 is different from the elliptical arc direction of the first sub-pixel sp1 in the third virtual quadrilateral 30; the second sub-pixel sp2 in the fourth virtual quadrilateral 40 is a special-shaped sub-pixel spx, and the elliptical arc direction of the second sub-pixel sp2 is different from the elliptical arc direction of the second sub-pixel sp2 in the fourth virtual quadrilateral 40.

[0124] In another embodiment, FIG. 24 is a schematic view of another display panel according to the present application, as shown in FIG. 24, four first sub-pixels sp1 form a third virtual quadrangle 30; one second virtual quadrangle 20 is located in the third virtual quadrangle 30, and the second virtual quadrangle 20 has one first sub-pixel sp1. The display panel includes a fourth virtual quadrangle 40, four second sub-pixels sp2 form the fourth virtual quadrangle 40; one second virtual quadrangle 20 is located in the fourth virtual quadrangle 40, and the second virtual quadrangle 20 has one second sub-pixel sp2. Among them, the four first sub-pixels sp1 forming the third virtual quadrangle 30 are all shaped sub-pixels spx, and the four second sub-pixels sp2 forming the fourth virtual quadrangle 40 are all shaped sub-pixels spx. Among them, the shape profile of the first sub-pixel sp1 located in the third virtual quadrangle 30 is circular; the shape profile of the second sub-pixel sp2 located in the fourth virtual quadrangle 40 is circular. In this embodiment, part of the plurality of first sub-pixels sp1 are shaped sub-pixels spx, and part are circular sub-pixels, and part of the plurality of second sub-pixels sp2 are shaped sub-pixels spx, and part are circular sub-pixels. The first sub-pixel sp1 and the second sub-pixel sp2 can also be designed by adjusting the elliptical arc direction of the first sub-pixel sp1 and the elliptical arc direction of the second sub-pixel sp2 to fine-tune the distance between the first sub-pixel sp1 and the second sub-pixel sp2, so that the distance between each first sub-pixel sp1 and second sub-pixel sp2 is relatively average, which can improve the problem of sub-pixel stealing light.

[0125] In another embodiment, the plurality of first sub-pixels sp1 in the display panel are all shaped sub-pixels spx, and part of the plurality of second sub-pixels sp2 are shaped sub-pixels spx and part are circular sub-pixels. In another embodiment, the plurality of second sub-pixels sp2 in the display panel are all shaped sub-pixels spx, and part of the plurality of first sub-pixels sp1 are shaped sub-pixels spx and part are circular sub-pixels. This will not be shown in the figure.

[0126] In some embodiments, FIG. 25 is a schematic view of another display panel provided by an embodiment of the present application. As shown in FIG. 25, two first sub-pixels sp1 and two second sub-pixels sp2 form a first virtual quadrilateral 10, the two first sub-pixels sp1 are located at a pair of opposite corners of the first virtual quadrilateral 10, the two second sub-pixels sp2 are located at another pair of opposite corners of the first virtual quadrilateral 10, and one third sub-pixel sp3 is located in the first virtual quadrilateral 10; four third sub-pixels sp3 form 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 forming the second virtual quadrilateral 20 are all special-shaped sub-pixels spz. In this embodiment, the third sub-pixel sp3 is set as a special-shaped sub-pixel spz, and by adjusting the elliptical arc direction of the special-shaped sub-pixel spz, the distance between the third sub-pixel spz and other color sub-pixels can be adjusted when the three types of sub-pixels are closely arranged, so that the distance between adjacent sub-pixels of different colors is relatively average, and the problem of sub-pixel stealing can be improved.

[0127] As shown in FIG. 25, the elliptical arc directions of the four third sub-pixels sp3 on the second virtual quadrilateral 20 are different, and the elliptical arc directions of the two third sub-pixels sp3 located at the opposite corners of the second virtual quadrilateral 20 are opposite. Such arrangement can make the arrangement of the three types of sub-pixels more compact, and improve the space utilization of the display panel. Moreover, arranging the display panel to have multiple third sub-pixels sp3 with different elliptical arc directions on the whole surface is beneficial to improving the display color deviation and can improve the large-angle display effect.

[0128] In some embodiments, the first virtual quadrilateral 10 is a square, and the second virtual quadrilateral 20 is a parallelogram. Alternatively, the second virtual quadrilateral 20 is a rectangle. Such arrangement can make the third sub-pixel sp3 uniformly 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.

[0129] In combination with FIG. 13, the pixel definition layer 05 of the display panel includes multiple openings K, and one sub-pixel sp includes one opening K; the opening K includes a first opening K1, and the special-shaped sub-pixel spx includes the first opening K1. The sub-pixel sp includes a shell 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 special-shaped sub-pixel spx is greater than the area of the first opening K1.

[0130] FIG. 26 is a simplified schematic diagram of another display panel according to an embodiment of the present application. FIG. 26 shows the pattern 42-p of the light-emitting layer of each sub-pixel sp, and the corresponding opening K. The first sub-pixel sp1 is taken as the special-shaped sub-pixel spx for illustration. As shown in FIG. 26, in the special-shaped sub-pixel spx, the pattern 42-p of the light-emitting layer is circular, and the center O1 of the pattern 42-p of the light-emitting layer does not coincide with the center O2 of the first opening K1. The pattern shape of the first opening K1 is the same as the outline shape of the special-shaped sub-pixel spx, and the center O2 of the first opening K1 is the barycenter of the pattern shape. In other embodiments, the pattern 42-p of the light-emitting layer is rectangular, which is not shown here. In the manufacture of the display panel, the light-emitting layer 42 is manufactured by evaporation process, and the light-emitting layer 42 is deposited in the opening K and extends to the outside. The shape of the mask in the evaporation process is the same as the pattern shape of the light-emitting layer. In the embodiment of the present application, the center O1 of the pattern 42-p of the light-emitting layer of the special-shaped sub-pixel spx does not coincide with the center O2 of the first opening K1, so the shape of the mask does not need to be changed for the shape of the special-shaped sub-pixel spx during evaporation.

[0131] In some embodiments, FIG. 27 is a schematic diagram of another display panel according to an embodiment of the present application. As shown in FIG. 27, 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 in which the substrate 00 lies, the hollow V at least partially overlaps 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 at least partially located in the hollow V. The reflection control layer 70 is an integral layer, or in other words, the reflection control layers 70 overlapping different color sub-pixels sp are connected as a whole. The reflection control layer 70 is an anti-reflection layer, which has the function of reducing the reflection of ambient light by the display panel. The reflection control layer 70 can selectively absorb some wave bands of ambient light incident on the display panel or absorb some wave bands of light reflected from the inside of the display panel. For example, the sub-pixels sp include red sub-pixels, green sub-pixels, and blue sub-pixels, and the reflection control layer 70 can absorb light of wave bands deviating from the wavelength range of the red sub-pixels, green sub-pixels, and blue sub-pixels, thereby being able to reduce the reflection of ambient light by the display panel while avoiding the reduction of display brightness. The material of the reflection control layer 70 includes dyes and pigments.

[0132] In some embodiments, the display panel further includes a support column. The support column is located in the orthographic projection of the substrate 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 evaporation yield.

[0133] FIG. 28 is a schematic view of another display panel according to an embodiment of the present application. FIG. 28 is a top view. It can be understood that the support columns in the top view coincide with their orthogonal projections on the substrate, and the sub-pixels in the top view coincide with their orthogonal projections on the substrate. As shown in FIG. 28, taking the first sub-pixel sp1 as an example of the special-shaped sub-pixel spx. The support column 80 includes a first support column 81 and a second support column 82. The orthogonal projection of the first support column 81 on the substrate is adjacent to the orthogonal projection of the circular arc l1 of the special-shaped sub-pixel spx on the substrate, and the orthogonal projection of the second support column 82 on the substrate is adjacent to the orthogonal projection of the elliptical arc l2 of the special-shaped sub-pixel spx on the substrate. In the direction parallel to the plane in which the substrate lies, the distance between the first support column 81 and the special-shaped sub-pixel spx is equal to the distance between the first support column 81 and the second sub-pixel sp2, and the distance between the second support column 82 and the special-shaped sub-pixel spx is less than the distance between the first support column 81 and the special-shaped sub-pixel spx. As shown in FIG. 28, the distance between the first support column 81 and the special-shaped sub-pixel spx is L1, and the distance between the second support column 82 and the special-shaped sub-pixel spx is L2, L2 < L1. The distance between the support column and the special-shaped sub-pixel spx is represented by the minimum distance therebetween, such as the distance between the support column and the edge of the first opening of the special-shaped sub-pixel spx. The top view of the support column 80 in FIG. 28 is only schematically represented, and is not a limitation on the present application.

[0134] The special-shaped sub-pixel spx shown in FIG. 28 is the shape shown in FIG. 11. The area of the special-shaped sub-pixel spx is greater than the area of the virtual circle in which the circular arc l1 lies. Therefore, the distance between the circular arc l1 of the special-shaped sub-pixel spx and the second sub-pixel sp2 is less than the distance between the elliptical arc l2 of the special-shaped sub-pixel spx and the second sub-pixel sp2. In the embodiments of the present application, L2 < L1 is set. The distance between the first support column 81 and the special-shaped sub-pixel spx can be equal to the distance between the first support column 81 and the second sub-pixel sp2, and the distance between the second support column 82 and the special-shaped sub-pixel spx can be equal to the distance between the second support column 82 and the second sub-pixel sp2. The support column can uniformly support the mask plate at each position, and the evaporation yield is ensured.

[0135] In some embodiments, the first sub-pixel sp1, one second sub-pixel sp2 adjacent to the first sub-pixel sp1, and one third sub-pixel sp3 adjacent to the first sub-pixel sp1 constitute one pixel. The first sub-pixel sp1 is shared by two adjacent pixels, and the second sub-pixel sp2 is shared by two adjacent pixels. The third sub-pixel sp3 is not shared by pixels. In the entire display area of the display panel, the ratio of the number of pixels to the number of support columns 80 is 2:9. Such a setting can ensure that the support column effectively and uniformly supports the mask plate in the evaporation process.

[0136] In some embodiments, the display panel further comprises a light sensor on one side of the substrate. The light sensor can be an ambient light sensor, which is used to sense the brightness of ambient light. The light sensor can be a false touch prevention sensor. The light sensor can also be an optical fingerprint sensor. In some embodiments, the light sensor is disposed at least in a partial display area of the display panel, and a projection of the light sensor on the substrate is located between projections of the first and second sub-pixels sp1 and sp2 on the substrate.

[0137] In one embodiment, FIG. 29 is a schematic diagram of another display panel according to an embodiment of the present application. As shown in FIG. 29, the first sub-pixel sp1 is a special-shaped sub-pixel spx. The light sensor 90 comprises a first light sensor 91 and a second light sensor 92. A projection of the first light sensor 91 on the substrate is adjacent to a projection of the circular arc l1 of the special-shaped sub-pixel spx on the substrate, and a projection of the second light sensor 92 on the substrate is adjacent to a projection of the elliptical arc l2 of the special-shaped sub-pixel spx on the substrate. In some embodiments, along a direction parallel to the plane of the substrate, the distance between the first light sensor 91 and the special-shaped sub-pixel spx is equal to the distance between the first light sensor 91 and the second sub-pixel sp2, and the distance between the second light sensor 92 and the special-shaped sub-pixel spx is less than the distance between the first light sensor 91 and the special-shaped sub-pixel spx. In FIG. 29, the distance between the first light sensor 91 and the special-shaped sub-pixel spx is L3, and the distance between the second light sensor 92 and the special-shaped sub-pixel spx is L4, L4 < L3. The distance between the light sensor 90 and the special-shaped sub-pixel spx is represented by the minimum distance therebetween, such as the distance between the light sensor 90 and the edge of the first opening of the special-shaped sub-pixel spx. The top view of the light sensor 90 in FIG. 29 is only schematic and is not intended to limit the present application.

[0138] The special-shaped sub-pixel spx in FIG. 29 has the shape shown in FIG. 11. The area of the special-shaped sub-pixel spx is greater than the area of the virtual circle on which the circular arc l1 is located, and thus the distance between the circular arc l1 of the special-shaped sub-pixel spx and the second sub-pixel sp2 is less than the distance between the elliptical arc l2 of the special-shaped sub-pixel spx and the second sub-pixel sp2. In the present embodiment, L4 < L3 is set, which can achieve that the distance between the first light sensor 91 and the special-shaped sub-pixel spx is equal to the distance between the first light sensor 91 and the second sub-pixel sp2, and can also achieve that the distance between the second light sensor 92 and the special-shaped sub-pixel spx is equal to the distance between the second light sensor 92 and the second sub-pixel sp2. In a display panel provided with a light-blocking structure (as shown in FIG. 13 or FIG. 27), the light-blocking structure also needs to be hollowed out for the light sensor 90. In the present embodiment, the light sensor 90 is disposed substantially at the middle position between the two sub-pixels, which avoids the influence of the light sensor 90 on the aperture ratio of the sub-pixels, and also enables the hollowed-out size of the light-blocking structure corresponding to the light sensor 90 to be large enough to ensure the optical performance of the light sensor 90.

[0139] In some embodiments, as shown in FIG. 29, the light sensor LS is located between the projections of the first sub-pixel sp1 and the second sub-pixel sp2 adjacent to the first sub-pixel sp1 in the second direction y, which is parallel to the plane where the substrate is located. The second direction y can be the extension direction of the data line or the extension direction of the scan line. The first sub-pixel sp1 and the second sub-pixel sp2 adjacent to the first sub-pixel sp1 and the third sub-pixel sp3 constitute a pixel, the first sub-pixel sp1 is shared by two adjacent pixels, the second sub-pixel sp2 is shared by two adjacent pixels, and the third sub-pixel sp3 is not shared by pixels. In the display area where the light sensor LS is arranged, the ratio of the number of pixels to the number of light sensors LS is 1:1. In the area where the light sensor LS is located in the embodiment of the present application, the density of the light sensor LS is large enough, and the light sensor LS is relatively uniformly distributed, which can ensure the reliable optical performance of the light sensor.
