[0002] In organic light-emitting diode (OLED) displays, the shape and arrangement of pixels directly affect the detail and sharpness of the image. Figure 1 As shown, conventional GGRB arrangement methods in existing technologies tend to produce a grainy appearance. Summary of the Invention

[0003] This invention provides a pixel structure and display panel to improve the problem that conventional pixel arrangement methods in the prior art are prone to producing a grainy appearance.

[0004] This invention provides a pixel structure, including: a plurality of repeating units, each repeating unit including: a first sub-pixel, two second sub-pixels and a third sub-pixel, the first sub-pixel and the third sub-pixel being arranged along a first direction, and the two second sub-pixels being arranged along a second direction; at least one side of at least one of the first sub-pixel and the third sub-pixel is a non-straight edge.

[0005] In one possible implementation, at least one of the first sub-pixel and the third sub-pixel has two adjacent edges that are concave.

[0006] In one possible implementation, a sub-pixel with two adjacent concave sides is a concave sub-pixel, the first bisector of the angle between the two concave adjacent sides is the first axis of symmetry of the concave sub-pixel, and the concave sub-pixel is asymmetrical in the direction perpendicular to the first bisector.

[0007] In one possible implementation, the concave sub-pixel further includes at least two adjacent straight lines, and the second bisector of the angle between the two straight lines coincides with the first axis of symmetry.

[0008] In one possible implementation, the maximum size of the concave sub-pixels is the same in both straight-line extension directions.

[0009] In one possible implementation, the size of the concave sub-pixel is the largest in the direction parallel to the first axis of symmetry, and is greater than the length of the straight side.

[0010] In one possible implementation, both the first sub-pixel and the third sub-pixel include concave edges;

[0011] The first sub-pixel and the third sub-pixel are arranged alternately in the first direction and alternately in a direction perpendicular to the first direction.

[0012] In one possible implementation, within the concave sub-pixel, the concave edge does not overlap with the first axis of symmetry.

[0013] In one possible implementation, the area of ​​the concave sub-pixel is 70% to 90% of the area of ​​the outer contour formed by connecting the vertices of the concave sub-pixel.

[0014] In one possible implementation, the plurality of repeating units include a plurality of pixel row groups that are repeatedly arranged along the second direction, each pixel row group including a first pixel row, a second pixel row, a first pixel row and a third pixel row arranged sequentially along the second direction;

[0015] The first pixel row includes: a first repeating unit and a second repeating unit arranged alternately along the first direction; the second pixel row includes: a third repeating unit arranged alternately along the first direction; the third pixel row includes: a fourth repeating unit arranged alternately along the first direction; the repeating units of the first pixel row are staggered from the repeating units of the second pixel row and the third pixel row.

[0016] In the first pixel row, the first axis of symmetry of the concave sub-pixels in each repeating unit is parallel to the first direction; in the second pixel row and the third pixel row, the first axis of symmetry of the concave sub-pixels in each repeating unit is parallel to the second direction.

[0017] In one possible implementation, the two adjacent edges of the first sub-pixel are concave; the first sub-pixel in the first repeating unit is disposed opposite to the first sub-pixel in the second repeating unit.

[0018] In one possible implementation, the first sub-pixel in the third repeating unit is positioned opposite to the first sub-pixel in the fourth repeating unit.

[0019] In one possible implementation, the two first sub-pixels that are parallel to the first direction and are closest to the third sub-pixel are symmetrical about a first straight line, the first straight line being parallel to the second direction and passing through a first center, the first center being the center of a quadrilateral formed by the centers of the four second sub-pixels closest to the third sub-pixel.

[0020] In one possible implementation, the two first sub-pixels that are parallel to the second direction and are closest to the third sub-pixel are symmetrical about a second straight line, which is parallel to the first direction and passes through the first center.

[0021] In one possible implementation, the two adjacent sides of the third sub-pixel are concave; the third sub-pixel in the first repeating unit is disposed opposite to the third sub-pixel in the second repeating unit.

[0022] In one possible implementation, the third sub-pixel in the third repeating unit is positioned facing the third sub-pixel in the fourth repeating unit.

[0023] In one possible implementation, the two third sub-pixels that are parallel to the first direction and are closest to the first sub-pixel are symmetrical about a third straight line, the third straight line being parallel to the first direction and passing through a third center, the third center being the center of a quadrilateral formed by the centers of the four second sub-pixels closest to the first sub-pixel.

[0024] In one possible implementation, the two third sub-pixels that are parallel to the second direction and are closest to the first sub-pixel are symmetrical about a fourth line, which is parallel to the second direction and passes through the third center.

[0025] In one possible implementation, the first sub-pixel is a red sub-pixel, the third sub-pixel is a blue sub-pixel, and the second sub-pixel is a green sub-pixel.

[0026] In one possible implementation, either side of the second sub-pixel is a straight line, and the lengths of adjacent sides are different.

[0027] Based on the same inventive concept, embodiments of the present invention also provide a display panel, including the pixel structure as described in the embodiments of the present invention.

[0028] The beneficial effects of the embodiments of the present invention are as follows: In the pixel structure of the embodiments of the present invention, there are multiple repeating units, each repeating unit including a first sub-pixel, two second sub-pixels and a third sub-pixel. The first sub-pixel and the third sub-pixel are arranged along a first direction, and the two second sub-pixels are arranged along a second direction. Compared with the traditional GGRB arrangement, this can improve the graininess. Moreover, at least one side of the first sub-pixel and the third sub-pixel is a non-straight side (such as a concave arc), which can have a larger space for the spacer (that is, the area between adjacent sub-pixels is the area where the pixel limiting layer is located. The increase in the space of the pixel limiting layer can also provide more space for the spacer located thereon). This can improve the problem of dark spots appearing in the display panel and has the advantage of increasing the aperture ratio (that is, if the spacer is small, it is easier to shift during manufacturing. The spacer may shift to the area where the sub-pixel is located, resulting in dark spots and a decrease in the aperture ratio). Attached Figure Description

[0051] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0052] See Figure 2 , Figure 3 and Figure 4As shown, this embodiment of the invention provides a pixel structure, including: a plurality of repeating units P, each repeating unit P including: a first sub-pixel X1, two second sub-pixels X2 and a third sub-pixel X3, the first sub-pixel X1 and the third sub-pixel X3 are arranged along a first direction A1, and the two second sub-pixels X2 are arranged along a second direction A2. Specifically, the first direction A1 and the second direction A2 can be perpendicular to each other; at least one side of at least one of the first sub-pixel X1 and the third sub-pixel X3 is a non-straight edge.

[0053] In this embodiment of the invention, the pixel structure includes: a plurality of repeating units P, each repeating unit P including: a first sub-pixel X1, two second sub-pixels X2, and a third sub-pixel X3. The first sub-pixel X1 and the third sub-pixel X3 are arranged along a first direction A1, and the two second sub-pixels X2 are arranged along a second direction A2. Figure 1 The traditional GRB arrangement shown can improve graininess; moreover, at least one side of at least one of the first sub-pixel X1 and the third sub-pixel X3 is a non-straight edge (such as a concave edge), which can provide more space for padding (such as...). Figure 2 The area indicated by the double arrows, that is, the area between adjacent sub-pixels, is the area where the pixel limiting layer is located. Increasing the space of the pixel limiting layer can also provide more space for the spacers located on it, which can improve the problem of dark spots appearing in the display panel and has the advantage of increasing the aperture ratio (that is, if the spacers are small, they are more likely to shift during manufacturing, and the spacers may shift into the area where the sub-pixels are located, resulting in dark spots and a decrease in the aperture ratio).

[0054] In specific implementation, at least one side of at least one of the first sub-pixel X1 and the third sub-pixel X3 is a non-linear side. The non-linear side can be a concave side, a convex side, or a curve, a broken line, or a wave shape.

[0055] Specifically, for example, a non-linear edge is a concave edge, such as... Figures 2-6A As shown, specifically, it can be that only the first sub-pixel X1 is concave, such as... Figure 3 As shown; it can also be that only the third sub-pixel X3 is concave, such as Figure 4 As shown; it can also be that only the second sub-pixel X2 is concave, such as Figure 5 As shown; specifically, it can be that two of the three sub-pixels, namely the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3, are concave, such as... Figure 2 As shown, the first pixel X1 and the third sub-pixel X3 are concave; specifically, all three sub-pixels—the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3—can be concave, as shown below. Figure 6A As shown, the first pixel X1 and the third sub-pixel X3 are concave.

[0056] In practical implementation, it is possible that at least one side of the first sub-pixel X1 is a concave arc shape, such as... Figure 3 As shown, specifically, it can be that only one side of the first sub-pixel X1 is a concave arc shape, or two sides of the first sub-pixel X1 are concave arc shapes, or three sides of the first sub-pixel X1 are concave arc shapes, or all four sides of the first sub-pixel X1 are concave arc shapes; it can also be that only at least one side of the third sub-pixel X3 is a concave arc shape, such as... Figure 4 As shown, specifically, it can be that only one side of the third sub-pixel X3 is a concave arc shape, or two sides of the third sub-pixel X3 are concave arc shapes, or three sides of the third sub-pixel X3 are concave arc shapes, or all four sides of the third sub-pixel X3 are concave arc shapes; it can also be that at least one side of both the first sub-pixel X1 and the third sub-pixel X3 is a concave arc shape, such as... Figure 2As shown, specifically, for example, one side of the first sub-pixel X1 could be a concave arc shape, and simultaneously, one side of the third sub-pixel could be a concave arc shape; another example is that one side of the first sub-pixel X1 could be a concave arc shape, and simultaneously, two sides of the third sub-pixel could be concave arc shapes; yet another example is that one side of the first sub-pixel X1 could be a concave arc shape, and simultaneously, three sides of the third sub-pixel could be concave arc shapes; yet another example is that one side of the first sub-pixel X1 could be a concave arc shape, and simultaneously, all four sides of the third sub-pixel could be concave arc shapes. The shape can be concave or curved. For example, the two sides of the first sub-pixel X1 can be concave arcs, and one side of the third sub-pixel can be concave arcs. Alternatively, the two sides of the first sub-pixel X1 can be concave arcs, and the two sides of the third sub-pixel can be concave arcs. Another example is that the two sides of the first sub-pixel X1 can be concave arcs, and the three sides of the third sub-pixel can be concave arcs. Yet another example is that the two sides of the first sub-pixel X1 can be concave arcs, and the four sides of the third sub-pixel can be concave. For example, the first sub-pixel X1 could have three concave arc-shaped sides, and one side of the third sub-pixel could also be a concave arc-shaped side. Alternatively, the first sub-pixel X1 could have three concave arc-shaped sides, and two sides of the third sub-pixel could also be concave arc-shaped sides. Another example is that the first sub-pixel X1 could have three concave arc-shaped sides, and three sides of the third sub-pixel could also be concave arc-shaped sides. Yet another example is that the first sub-pixel X1 could have three concave arc-shaped sides, and all four sides of the third sub-pixel could also be concave arc-shaped sides. For example, the four sides of the first sub-pixel X1 can be concave arcs, and one side of the third sub-pixel can be concave arcs. Alternatively, the four sides of the first sub-pixel X1 can be concave arcs, and two sides of the third sub-pixel can be concave arcs. Alternatively, the four sides of the first sub-pixel X1 can be concave arcs, and three sides of the third sub-pixel can be concave arcs. Alternatively, the four sides of the first sub-pixel X1 can be concave arcs, and four sides of the third sub-pixel can be concave arcs.

[0057] Specifically, for example, a non-linear edge is a convex edge; specifically, for example, such as... Figure 7 The first sub-pixel X1 has a convex edge. Of course, it is also possible for the third sub-pixel X3 to have a convex edge, or for the second sub-pixel X2 to have a convex edge, or for the first sub-pixel X1 and the third sub-pixel X3 to have convex edges, or for the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 to all have convex edges. Specifically, each sub-pixel can have one convex edge, two convex edges, three convex edges, or four convex edges.

[0058] In one possible implementation, when the first sub-pixel X1 and / or the third sub-pixel X3 have concave or convex edges, the second sub-pixel X3 may have an edge that complements the edges of the first sub-pixel X1 and / or the third sub-pixel X3, so that the minimum spacing between the opposite edges of adjacent sub-pixels is the same. For example, combining... Figure 6B As shown, the first sub-pixel X1 has a concave edge, and the opposite edge of the second sub-pixel X2 can be a convex edge; similarly, the third sub-pixel X3 has a concave edge, and the opposite edges of the second sub-pixel X2 and the third sub-pixel X3 can be convex edges. Alternatively, for example, the first sub-pixel X1 has a convex edge, and the opposite edge of the second sub-pixel X2 can be a concave edge; similarly, the third sub-pixel X1 has a convex edge, and the opposite edges of the second sub-pixel X2 and the third sub-pixel X3 can be concave edges.

[0059] Figures 2-7 This is merely an illustrative example using the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 as quadrilaterals. In actual implementation, at least one of the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 can also be a triangle, a pentagon, a hexagon, an octagon, a circle, an ellipse, or other shapes. Specifically, when at least one of the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 is a triangle, the triangular sub-pixel can have concave sides, such as... Figure 9A As shown; specifically, when at least one of the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 is a pentagon, the pentagonal sub-pixel can have concave sides, such as... Figure 9B As shown; specifically, when at least one of the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 is hexagonal, the hexagonal sub-pixel can have concave sides, such as... Figure 9C As shown; specifically, when at least one of the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 is an octagon, the octagonal sub-pixel can have concave edges, such as... Figure 9D As shown; specifically, when at least one of the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 is circular, the circular sub-pixel can have a concave edge, such as... Figure 9E As shown; specifically, when at least one of the first sub-pixel X1, the second sub-pixel X2, and the third sub-pixel X3 is elliptical, the elliptical sub-pixel can have a concave edge, such as... Figure 9F As shown.

[0060] In one possible implementation, such as Figure 8As shown, the first sub-pixel X1 can be hexagonal, the second sub-pixel X2 can be pentagonal, and the third sub-pixel X3 can be hexagonal. Specifically, the opposite sides of the two second sub-pixels X2 can be concave, which can increase the spacing between the centers of the second sub-pixels X2 and make it easier to achieve a uniform distribution of the brightness center of the second sub-pixels X2.

[0061] In specific implementation, the first sub-pixel X1 can be a red sub-pixel, the third sub-pixel X3 can be a blue sub-pixel, and the second sub-pixel X2 can be a green sub-pixel. Specifically, either side of the second sub-pixel X2 is a straight line, and the lengths of adjacent sides are different. In this embodiment of the invention, selecting the sides of the first sub-pixel X1 and / or the third sub-pixel X3 as concave arcs can avoid the difficulties in manufacturing the concave shape due to the different lengths of the adjacent sides of the green second sub-pixel X2, and the asymmetry of the sub-pixel pattern formed after the concave shape of its adjacent sides, which would cause color shift and inconsistent brightness on the display panel when viewed from an oblique angle.

[0062] In one possible implementation, combined with Figures 2-4 As shown, at least one of the first sub-pixel X1 and the third sub-pixel X3 has two adjacent sides that are concave. Specifically, this concavity allows the first sub-pixel X1 and / or the third sub-pixel X3 to form an arrow-like shape, that is, at least one of the first sub-pixel X1 and the third sub-pixel X3 has a shape similar to a "manta ray". In this embodiment of the invention, the concavity of the two adjacent sides of at least one of the first sub-pixel X1 and the third sub-pixel X3 can facilitate the symmetrical distribution of multiple first sub-pixels X1 and multiple third sub-pixels X3, while avoiding the problem of the light-emitting area being too small, which would affect the normal display of the display panel.

[0063] In one possible implementation, combined with Figure 10 As shown, a subpixel with two adjacent concave sides is a concave subpixel. The first bisector of the angle between the two concave adjacent sides is the first axis of symmetry d1 of the concave subpixel, and the concave subpixel is asymmetrical in the direction perpendicular to the first bisector. Specifically, for example, if the two adjacent sides of the first subpixel X1 are concave, the first subpixel X1 can be considered a concave subpixel; if the two adjacent sides of the third subpixel X3 are concave, the third subpixel X3 can be considered a concave subpixel.

[0064] In one possible implementation, combined with Figure 10 As shown, the concave sub-pixel also includes at least two adjacent straight line sides, and the second bisector of the angle between the two straight line sides coincides with the first axis of symmetry d1.

[0065] In one possible implementation, combined with Figure 10As shown, the maximum size of the concave sub-pixels is the same along the two straight edge extension directions. Specifically, combining... Figure 10 As shown, for example, the first sub-pixel X1 is a concave sub-pixel. The maximum size of the first sub-pixel X1 in the direction of one straight edge extension is c1, and the maximum size in the direction of the other straight edge extension is c2. Specifically, c1 and c2 can be the same.

[0066] In one possible implementation, combined with Figure 10 As shown, in the direction parallel to the first axis of symmetry d1, the size of the concave sub-pixel is the largest, and it is greater than the length of the straight side. Specifically, combined with... Figure 10 As shown, for example, the first sub-pixel X1 is a concave sub-pixel. In the direction parallel to the first axis of symmetry d1, the size of the first sub-pixel X1 is c3. Specifically, c3 can be greater than c1 and greater than c2.

[0067] In one possible implementation, combined with Figure 10 As shown, both the first sub-pixel X1 and the third sub-pixel X2 include concave edges; the first sub-pixel X1 and the third sub-pixel X3 are alternately arranged in the first direction A1 and also alternately arranged in a direction perpendicular to the first direction A1. Specifically, in the first direction A1, the nearest distance between adjacent first sub-pixel X1 and third sub-pixel X3 is c4, and in the second direction A2, the nearest distance between adjacent first sub-pixel X1 and third sub-pixel X3 is c5. The ratio of c4 to c5 can range from 0.8 to 1.2, specifically, the ratio of c4 to c5 can be 1, that is, they are equal.

[0068] In one possible implementation, combined with Figure 10 As shown, within the concave sub-pixel, the concave edge does not overlap with the first axis of symmetry d1. That is, the concave edge does not exceed the first axis of symmetry d1 to avoid the concave area being too large, which would reduce the effective light-emitting area too much and affect the normal display of the display panel. Specifically, the area of ​​the concave sub-pixel is 70% to 90% of the area of ​​the outer contour E formed by connecting the vertices of the concave sub-pixel. Specifically, the area of ​​the concave sub-pixel can be 77% to 85% of the area of ​​the outer contour E formed by connecting the vertices of the concave sub-pixel; specifically, the area of ​​the concave sub-pixel can be 70%, 80%, or 90% of the area of ​​the outer contour E formed by connecting the vertices of the concave sub-pixel.

[0069] In one possible implementation, combined with Figure 10 As shown, concave sub-pixels (such as...) Figure 10The first sub-pixel X1 and the third sub-pixel X3 have a first axis of symmetry d1. Specifically, the second sub-pixel X2 may have a second axis of symmetry d2 and a third axis of symmetry d3. Specifically, at least some of the extension directions of the first axis of symmetry d1, the second axis of symmetry d2, and the third axis of symmetry d3 may be different. For example, the extension directions of the second axis of symmetry d2 and the third axis of symmetry d3 are different. For example, the extension directions of the first axis of symmetry d1 are different from those of the second axis of symmetry d2 and the third axis of symmetry d3.

[0070] In one possible implementation, combined with Figure 10 As shown, in the first direction A1, the center O11 of the first sub-pixel X1 and the center O13 of the third sub-pixel X3 are arranged alternately; in the second direction A3, the center O11 of the first sub-pixel X1 and the center O13 of the third sub-pixel X3 are arranged alternately. Specifically, in the first direction A, the distance between the center O11 of two adjacent first sub-pixels X1 is c6, and the distance between the center O13 of two adjacent third sub-pixels X3 is c7. Specifically, c6 and c7 can be equal. Specifically, in the second direction A, the distance between the center O11 of two adjacent first sub-pixels X1 is c8, and the distance between the center O13 of two adjacent third sub-pixels X3 is c9. Specifically, c8 and c9 can be equal.

[0071] In one possible implementation, combined with Figure 10 As shown, the center O11 of the two first sub-pixels X1 adjacent to the second sub-pixel X2 and the center O13 of the two third sub-pixels X3 can form a first quadrilateral F1. Specifically, the first quadrilateral F1 can be a rectangle, a parallelogram, a trapezoid, or other irregular quadrilateral.

[0072] In one possible implementation, combined with Figure 10 As shown, the centers O2 of the four second sub-pixels X2 adjacent to a first sub-pixel X1 can form a second quadrilateral F2. Specifically, the second quadrilateral F2 can be a rectangle, a parallelogram, a trapezoid, or other irregular quadrilateral. The centers O2 of the four second sub-pixels X2 adjacent to a third sub-pixel X3 can form a third quadrilateral F3. Specifically, the third quadrilateral F3 can be a rectangle, a parallelogram, a trapezoid, or other irregular quadrilateral.

[0073] In one possible implementation, combined with Figure 10 As shown, the interior angles of the first quadrilateral F1 can range from 80 degrees to 100 degrees, specifically, for example, 90 degrees; in one possible implementation, combined with Figure 10 As shown, the interior angles of the second quadrilateral F2 can range from 80 degrees to 100 degrees, specifically, for example, 90 degrees; in one possible implementation, combined with Figure 10As shown, the interior angles of the third quadrilateral F3 can range from 80 degrees to 100 degrees, specifically, for example, 90 degrees.

[0074] In one possible implementation, combined with Figures 2-4 as well as Figure 10 As shown, the multiple repeating units P include multiple pixel row groups that are arranged in a repeating manner along the second direction A2. Each pixel row group includes: a first pixel row S1, a second pixel row S2, a first pixel row S1 and a third pixel row S3 arranged in a repeating manner along the second direction A2.

[0075] The first pixel row S1 includes: a first repeating unit P11 and a second repeating unit P12 arranged alternately along the first direction A1; the second pixel row S2 includes: a third repeating unit P21 arranged alternately along the first direction A1; the third pixel row S3 includes: a fourth repeating unit P31 arranged alternately along the first direction A1; the repeating units P of the first pixel row S1 are staggered from the repeating units P of the second pixel row S2 and the third pixel row S3;

[0076] In the first pixel row S1, in each repeating unit P, the first axis of symmetry d1 of the concave sub-pixel is parallel to the first direction A1, specifically, as follows: Figure 2 In the first pixel row S1, within the first repeating unit P11, the first axis of symmetry d1 of the first sub-pixel X1 is parallel to the first direction A1, and the first axis of symmetry d1 of the third sub-pixel X3 is parallel to the first direction A1. That is, the arrow-shaped first sub-pixel X1 points to the left, and the third sub-pixel X3 points to the left, both pointing parallel to the first direction A1. Within the second repeating unit P12 of the first pixel row S1, the first sub-pixel X1 points to the right, and the third sub-pixel X3 points to the right, both pointing parallel to the first direction A1. In the second pixel row S2, the first axis of symmetry d1 of the concave sub-pixels within each repeating unit P is parallel to the second direction A2. That is, the arrow-shaped first sub-pixel X1 and / or the third sub-pixel X3 point parallel to the second direction A2. Specifically, as shown...

Specifically, for example, as... Figure 2 In the first pixel row S1, the third sub-pixel X3 in the first repeating unit P11 points to the left, and the third sub-pixel X3 in the second repeating unit P12 points to the right. The two points are opposite, so that two adjacent third sub-pixels X3 in the same row can be symmetrical.

[0083] In one possible implementation, combined with Figure 2 and Figure 4 As shown, the third sub-pixel X4 in the third repeating unit P21 and the third sub-pixel X3 in the fourth repeating unit P31 are positioned facing each other.

[0089] In one possible implementation, for the distribution of the edge columns of the display area, the concave portion can correspond to the portion closer to the edge, which can reduce edge color shift.

[0090] In one possible implementation, the sub-pixel shape of the present invention can not only be improved at the edges, but can also be combined with other shapes to adjust the display center of gravity.

[0091] Specifically, in combination Figure 11 The diagram shown is a comparison of the pixel arrangement structure (devil ray) provided in this embodiment of the invention with other pixel arrangement structures, highlighting their graininess. Figure 11It can be seen that the stingray pixel arrangement structure provided in this embodiment of the invention displays a grainy appearance that is not significantly different from the diamond pixel arrangement structure, and is superior to the GGRB pixel arrangement structure; for example Figure 12 The image shown is a comparison of color shift simulations in different directions between the pixel arrangement structure (devil ray) provided in this embodiment of the invention and other pixel arrangement structures. Figure 12 It can be seen that the manta ray pixel arrangement structure provided in the embodiments of the present invention is superior to GGRB and comparable to the Diamond and Magic pixel arrangement structures; for example Figure 13 The image shown is a simulation comparison of brightness attenuation in different directions between the pixel arrangement structure (devil ray) provided in this embodiment of the invention and other pixel arrangement structures. Figure 13 It can be seen that the manta ray pixel arrangement structure provided in this embodiment of the invention is superior to GGRB in terms of brightness decay, and comparable to Diamond and Magic. In summary, compared with traditional GGRB, the pixel arrangement structure provided in this embodiment of the invention provides finer text display (stronger graininess), a lighter bias for angled characters, and better brightness decay (L-decay). Compared with Diamond, the pixel arrangement structure provided in this embodiment of the invention allows for wider space in the pixel limiting layer (PDL) gap for spacers, which can improve the problem of dark spots easily appearing on the display panel, and has the advantage of increasing aperture ratio, such as... Figure 14 As shown.

[0092] Based on the same inventive concept, embodiments of the present invention also provide a display panel, including the pixel structure provided in embodiments of the present invention.

[0093] The beneficial effects of the embodiments of the present invention are as follows: In the embodiments of the present invention, the pixel structure includes: a plurality of repeating units P, each repeating unit P including: a first sub-pixel X1, two second sub-pixels X2 and a third sub-pixel X3, the first sub-pixel X1 and the third sub-pixel X3 are arranged along a first direction A1, and the two second sub-pixels X2 are arranged along a second direction A2, relative to Figure 1 The traditional GRB arrangement shown can improve graininess; moreover, at least one side of at least one of the first sub-pixel X1 and the third sub-pixel X3 is a non-straight side (such as a concave arc), which can provide more space for padding (such as...). Figure 2 The area indicated by the double arrows, that is, the area between adjacent sub-pixels, is the area where the pixel limiting layer is located. Increasing the space of the pixel limiting layer can also provide more space for the spacers located on it, which can improve the problem of dark spots appearing in the display panel and has the advantage of increasing the aperture ratio (that is, if the spacers are small, they are more likely to shift during manufacturing, and the spacers may shift into the area where the sub-pixels are located, resulting in dark spots and a decrease in the aperture ratio).
