[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "an", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0020] An embodiment of the present invention provides a display panel in which the arrangement of support pillars is designed in accordance with the arrangement of sub-pixels. This ensures that the support pillars can evenly support the mask during the sub-pixel evaporation process, thereby ensuring the yield of the evaporation process and improving the display effect.

[0021] The display panel provided by the embodiment of the present invention includes a plurality of repeating units, each of which includes a plurality of sub-pixels and a plurality of support columns. The plurality of repeating units are periodically arranged in the display panel. Figure 1 A schematic diagram of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the subpixels sp in the display panel include a first subpixel sp1, a second subpixel sp2, and a third subpixel sp3 of different colors. The first subpixel sp1, the second subpixel sp2, and the third subpixel sp3 are respectively one of red, green, and blue subpixels. When the display panel is displaying, the first subpixel sp1 and its adjacent second subpixel sp2 and third subpixel sp3 constitute a pixel P. The second subpixel sp2 is shared by the two adjacent pixels P, and the third subpixel sp3 is shared by the two adjacent pixels P. Adjacent pixels P do not share the first subpixel sp1. One pixel P serves as a display unit, which can improve the display resolution of the display panel.

[0022] like Figure 1 FIG. 1 shows a repeating unit Y in the display panel. In the display panel, a plurality of repeating units Y are periodically arranged, and adjacent repeating units Y share a sub-pixel sp and a support column 10 on one side.

[0023] The repeating unit Y includes a first virtual quadrilateral 20, and a support column 10 is respectively arranged at the four vertex positions of the first virtual quadrilateral 20. In addition to the support columns 10 located at the vertex positions, one or two support columns 10 are also arranged on the sides of the first virtual quadrilateral 20, and multiple support columns 10 are arranged inside the first virtual quadrilateral 20; among them, the support columns 10 located at the vertex positions contribute one-quarter of the support columns 10 to the repeating unit Y, the support columns 10 located on the sides of the first virtual quadrilateral 20, except the support columns 10 located at the vertex positions, contribute half of the support columns 10 to the repeating unit Y, and each support column 10 located inside the first virtual quadrilateral 20 contributes one support column 10 to the repeating unit Y. According to the above calculation method, the four support pillars 10 located at the four corners of the first virtual quadrilateral 20 contribute one support pillar 10 to the repeating unit Y. In addition to the support pillars 10 located at the corners, there are a total of six support pillars 10 located on the sides of the first virtual quadrilateral 20. These six support pillars 10 contribute three support pillars 10 to the repeating unit Y. Eight more support pillars 10 are located within the first virtual quadrilateral 20. Therefore, the repeating unit Y includes a total of 12 support pillars 10.

[0024] The sub-pixel sp located on the edge of the first virtual quadrilateral 20 contributes half a sub-pixel to the repeating unit Y, and the sub-pixel sp located inside the first virtual quadrilateral 20 contributes one sub-pixel to the repeating unit Y. Calculating the number of sub-pixels in the above manner, it can be seen that the repeating unit Y includes 36 first sub-pixels sp1, 18 second sub-pixels sp2, and 18 third sub-pixels sp3. Combined with the composition of the pixel P, it can be seen that Figure 1 The repeating unit Y shown in FIG includes 36 pixels in total.

[0025] In this embodiment of the present invention, the ratio of the number of support pillars 10 to the number of pixels P within a repeating unit Y is 1:3. That is, a support pillar 10 is located at the position of every three pixels P. The density of support pillars 10 in the display panel is relatively high. During display panel manufacturing, the support pillars 10 can uniformly and effectively support the high-precision mask used in the vapor deposition process for each color sub-pixel SP, ensuring uniform vapor deposition of each color sub-pixel SP and preventing color shift in the display caused by poor vapor deposition.

[0026] In some embodiments, the first sub-pixel sp1 is a green sub-pixel, and one of the second sub-pixel sp2 and the third sub-pixel sp3 is a red sub-pixel and the other is a blue sub-pixel.

[0027] In some embodiments, Figure 2 A schematic diagram of another display panel provided by an embodiment of the present invention,

[0028] Figure 2 A repeating unit Y is shown schematically in FIG. Figure 3 for Figure 2 A partially enlarged schematic diagram of a display panel provided in an embodiment.

[0029] like Figure 2 As shown, two second sub-pixels sp2 and two third sub-pixels sp3 form a first virtual trapezoid 30. The centers of the second sub-pixel sp2 and the third sub-pixel sp3 are respectively located at the vertices of the first virtual trapezoid 30, and the sub-pixels sp located at the diagonals of the first virtual trapezoid 30 have the same color. A first sub-pixel sp1 is disposed within the first virtual trapezoid 30. A first sub-pixel sp1 and three other first sub-pixels sp1 located within the first virtual trapezoid 30 form a second virtual trapezoid 40. The center of the first sub-pixel sp1 is located at a vertex of the second virtual trapezoid 40. A second sub-pixel sp2 or a third sub-pixel sp3 is disposed within the second virtual trapezoid 40. In the embodiment of the present invention, the sub-pixel sp is an organic light-emitting device or an inorganic light-emitting device. The sub-pixel sp includes a stacked first electrode, a light-emitting layer, and a second electrode. The center of the sub-pixel sp is understood to be the geometric center of the light-emitting layer pattern.

[0030] Figure 3 FIG. 3 shows a first virtual trapezoid 30 and a second virtual trapezoid 40. Figure 3 It can be seen that both the first virtual trapezoid 30 and the second virtual trapezoid 40 include two parallel sides and two oblique sides. The parallel sides of the first virtual trapezoid 30 include the first short side 3-1 and the first long side 3-2. The length of the first short side 3-1 is less than the length of the first long side 3-2. The angle formed between the first long side 3-2 and one oblique side of the first virtual trapezoid 30 is α1, and the angle formed between the first long side 3-2 and the other oblique side is α2. α1 and α2 are the base angles of the first virtual trapezoid 30, respectively. The parallel sides of the second virtual trapezoid 40 include the second short side 4-1 and the second long side 4-2. The length of the second short side 4-1 is less than the length of the second long side 4-2. The angle formed between the second long side 4-2 and one oblique side of the second virtual trapezoid 40 is β1, and the angle formed between the second long side 4-2 and the other oblique side is β2. β1 and β2 are the base angles of the second virtual trapezoid 40, respectively.

[0031] Among them, │(α1+α2)-(β1+β2)│≤10°. In an embodiment of the present invention, the centers of the two second sub-pixels sp2 and the two third sub-pixels sp3 constitute a first virtual trapezoid 30, that is, there is a misalignment between the second sub-pixels sp2 and the third sub-pixels sp3 arranged in the first direction x. In other words, there is an offset in the second sub-pixel sp2 or the third sub-pixel sp3 in the first direction x. This can weaken the color fringing phenomenon on the edge of the display area along the first direction x. The four first sub-pixels sp1 constitute a second virtual trapezoid 40, then there is a misalignment between the first sub-pixels sp1 arranged in the second direction y, in other words, there is an offset in some of the first sub-pixels sp1 arranged in the second direction y. Then the number of first sub-pixels sp1 exposed separately in the second direction y will become smaller, thereby weakening the color fringing phenomenon on the edge of the display area along the second direction y. At the same time, the difference between the sum of the base angles of the two trapezoids is within a predetermined range. This, on the one hand, can simultaneously improve color fringing along all edges of the display panel. On the other hand, the offset of the three sub-pixels can be adjusted so that the first virtual trapezoid 30 and the second virtual trapezoid 40 form a regular pattern with minimal differences, which improves the display effect when displaying text and ensures display uniformity. Furthermore, the offset first sub-pixel sp1 can be positioned closer to the other two sub-pixels, minimizing color fringing. Compared to conventional diamond arrangements, the display panel provided by the present invention can minimize color fringing and improve the display quality.

[0032] In some embodiments, α1=α2. This configuration makes the arrangement of the second sub-pixel sp2 and the third sub-pixel sp3 more uniform and compact, which is beneficial to ensuring the display effect and aperture ratio of the display panel.

[0033] In some embodiments, β1=β2. This configuration makes the arrangement of the first sub-pixel sp1 and the third sub-pixel sp3 more uniform, which is beneficial to ensuring the display effect of the display panel.

[0034] In some embodiments, α1=α2=β1=β2.

[0035] Combine Figure 3 As shown in FIG, the first virtual trapezoid 30 includes two parallel sides and two oblique sides. Figure 2 As shown, part of the support column 10 is located on the parallel sides of the first virtual trapezoid 30, as shown in FIG. Figure 2 The support column 10 in the first virtual trapezoid 30-1 is shown in FIG; the remaining support columns 10 are located on the hypotenuse of the first virtual trapezoid 30, as shown in FIG. Figure 2The support column 10 in the first virtual trapezoid 30-2 is shown in FIG. In the first virtual trapezoid 30, the extension directions of the parallel sides and the oblique sides are different. When the support column 10 is located on the parallel sides of the first virtual trapezoid 30, the two sides of the support column 10 in the second direction y are adjacent to the second sub-pixel sp2 and the third sub-pixel sp3 respectively. When the support column 10 is located on the oblique side of the first virtual trapezoid 30, the two sides of the support column 10 in the first direction x are adjacent to the second sub-pixel sp2 and the third sub-pixel sp3 respectively. The first direction x intersects the second direction y. When the display panel is displaying, the support column 10 will have a certain degree of influence on the light output of the adjacent sub-pixel sp, that is, the support column 10 will block the light output of the adjacent sub-pixel sp. The design of the embodiment of the present invention allows the support column 10 to block the light emitted from the second sub-pixel sp2 and the light emitted from the third sub-pixel sp3 in both the first direction x and the second direction y, rather than blocking the light emitted from the sub-pixel sp in only one direction. Furthermore, the support column 10 has substantially the same effect on the light emitted from the second sub-pixel sp2 and the light emitted from the third sub-pixel sp3. This can improve the color shift problem at different viewing angles and enhance the overall display quality.

[0036] In some embodiments, Figure 4 for Figure 2 A partial enlarged schematic diagram of a display panel provided in the embodiment. Figure 4 As shown, the minimum distance between the support column 10 and the second sub-pixel sp2 closest to it is d1, and the minimum distance between the support column 10 and the third sub-pixel sp3 closest to it is d2, d1=d2. Among them, the minimum distance between the support column 10 and the sub-pixel sp adjacent to it is calculated as the distance between the edge of the support column 10 and the edge of the sub-pixel sp. When the display panel is manufactured, the support column 10 can support the mask used when evaporating the second sub-pixel sp2, and can also support the mask used when evaporating the third sub-pixel sp3. In the embodiment of the present invention, the minimum distance between the support column 10 and the second sub-pixel sp2 is equal to the minimum distance between the support column 10 and the third sub-pixel sp3, ensuring that when there is a certain range of alignment deviation between the mask and the display panel to be evaporated during the evaporation process, the support column 10 can still effectively support the mask, thereby improving the yield of the evaporation process. In addition, it can also ensure that the support column 10 has substantially the same influence on the light emission of the second sub-pixel sp2 and the third sub-pixel sp3 on both sides thereof, thereby improving the problem of display color shift under different viewing angles.

[0037] In some embodiments, Figure 5 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Figure 5As shown, the repeating unit Y includes three support column rows 10H extending in a first direction x and arranged in a second direction y. The support columns 10 in the three support column rows 10H are all located on parallel sides of the first virtual trapezoid 30 in which they are located; the support columns 10 arranged between two adjacent support column rows 10H are all located on the hypotenuse of the first virtual trapezoid 30 in which they are located. The support columns 10 located on the parallel sides of the first virtual trapezoid 30 will block the light emitted by the second sub-pixel sp2 and the third sub-pixel sp3 in the second direction y, and the support columns 10 located on the hypotenuse of the first virtual trapezoid 30 will block the light emitted by the second sub-pixel sp2 and the third sub-pixel sp3 in the first direction x. In this embodiment, support columns 10 located on the parallel sides of the first virtual trapezoid 30 and support columns 10 located on the oblique sides of the first virtual trapezoid 30 are arranged alternately in the second direction y, so that the support columns 10 can alternately block the light emitting from the second sub-pixel sp2 in the first direction x and the light emitting from the second sub-pixel sp2 in the second direction y. The support columns 10 also alternately block the light emitting from the third sub-pixel sp3 in the first direction x and the light emitting from the third sub-pixel sp3 in the second direction y, which can improve the uniformity of the light emitting from the second sub-pixel sp2 and the third sub-pixel sp3 in different directions, and further improve the color deviation problem of display under different viewing angles.

[0038] like Figure 5 As shown, the oblique sides of the support pillars 10 between two adjacent support pillar rows 10H and the parallel sides of the support pillars 10 in the support pillar row 10H do not belong to the same first virtual trapezoid 30. Figure 5 The first virtual trapezoid 30-3 and the first virtual trapezoid 30-4 are shown in FIG. Support column 10-1 is located in support column row 10H, while support column 10-2 is located between two adjacent support column rows 10H. Specifically, support column 10-1 is located on a parallel side of first virtual trapezoid 30-3, and support column 10-2 is located in first virtual trapezoid 30-4. Support column 10-1 and support column 10-2 belong to different first virtual trapezoids 30. This arrangement ensures that the distance between support columns 10 located between two adjacent support column rows 10H and the two support column rows 10H in the second direction y is not too different, thereby improving the uniformity of the arrangement of support columns 10 in the second direction y and ensuring that support locations 10 can effectively and uniformly support the mask.

[0039] like Figure 5As shown, the support pillars 10 in the same support pillar row 10H are all located on the first short side 3-1 or the first long side 3-2. In two adjacent support pillar rows 10H, the support pillars 10 in one support pillar row 10H are located on the first short side 3-1, and the support pillars 10 in the other support pillar row 10H are located on the first long side 3-2. In a repeating unit Y, the support pillars 10 in the first support pillar row 10H and the third support pillar row 10H arranged in the second direction y are both located on the first long side 3-2, while the support pillars 10 in the second support pillar row 10H are both located on the first short side 3-1. In this embodiment, the positions of the support columns 10 in the support column row 10H within the first virtual trapezoid 30 in which they are located are arranged, which can further improve the regularity of the arrangement of the support columns 10, so that in the first direction x and the second direction y, the support columns 10 have substantially the same impact on the light output of the second sub-pixel sp2 and the light output of the third sub-pixel sp3. This can thereby improve the color shift problem of the display under different viewing angles and enhance the overall display effect. In addition, this embodiment is combined with the above-mentioned embodiment in which the support columns 10 in two adjacent support column rows 10H are all located on parallel sides of the first virtual trapezoid 30 in which they are located. Then, within the repeating unit Y, the arrangement regularity of the support columns 10 in the second direction y is as follows: located on the first short side of the first virtual trapezoid 30, located on the hypotenuse of the first virtual trapezoid 30, located on the first long side of the first virtual trapezoid 30, located on the hypotenuse of the first virtual trapezoid 30, and located on the first short side of the first virtual trapezoid 30, and so on. The support columns 10 are arranged regularly, so that the support columns 10 alternately block the light emitting from the second sub-pixel sp2 in the first direction x and in the second direction y, and the support columns 10 also alternately block the light emitting from the third sub-pixel sp3 in the first direction x and in the second direction y, which can improve the uniformity of the light emitting from the second sub-pixel sp2 and the third sub-pixel sp3 in different directions, and further improve the color deviation problem of display under different viewing angles.

[0040] like Figure 5 As shown, the number of support pillars 10 in the three support pillar rows 10H is equal, and the number of support pillars 10 in two adjacent support pillar rows 10H is a constant value. Figure 5 In this embodiment, the number of support pillars 10 in a support pillar row 10H is 4, and the number of support pillars 10 in two adjacent support pillar rows 10H is 3. In this embodiment of the present invention, the support pillars 10 in a support pillar row 10H are located on parallel sides of the first virtual trapezoid 30 in which they are located, and the support pillars 10 in two adjacent support pillar rows 10H are located on the oblique sides of the first virtual trapezoid 30 in which they are located. Furthermore, setting the number of support pillars 10 in two adjacent support pillar rows 10H to a fixed value can improve the uniformity of the arrangement of the support pillars 10, ensure that the support pillars 10 effectively and uniformly support the mask, and improve the yield rate of sub-pixel sp evaporation.

[0041] Continue to refer Figure 5 As shown, a support column row 10H includes four support columns 10; three support columns 10 are arranged between two adjacent support column rows 10H, and the three support columns 10 are located in the same row in the first direction x. Figure 5 For example, the first support column row 10H, the second support column row 10H, and the third support column row 10H are arranged in sequence from bottom to top in the second direction y. The support column 10 between the first support column row 10H and the second support column row 10H is adjacent to the second sub-pixel sp2 on its left side in the first direction x, and adjacent to the third sub-pixel sp3 on its right side in the first direction x; the support column 10 between the second support column row 10H and the third support column row 10H is adjacent to the third sub-pixel sp3 on its left side in the first direction x, and adjacent to the second sub-pixel sp2 on its right side in the first direction x. That is, in a repeating unit Y, the support column 10 located between two adjacent support column rows 10H is located on the hypotenuse of the first virtual trapezoid 30 in which it is located, and the three arranged support column rows 10H are equivalent to dividing the support columns 10 located on the hypotenuse of the first dotted trapezoid 30 into two types. One type of support column 10 is adjacent to the second sub-pixel sp2 on the left side and the third sub-pixel sp3 on the right side in the first direction x, while another type of support column 10 is adjacent to the third sub-pixel sp3 on the left side and the second sub-pixel sp2 on the right side in the first direction x. Furthermore, by setting the number of support columns 10 between two adjacent support column rows 10H to a fixed value, the number of the two types of support columns 10 within the repeating unit Y can be equal. With this arrangement, when a user views the display panel from the left side in the first direction x, some support columns 10 block the light emitted from the second sub-pixel sp2, and some support columns 10 block the light emitted from the third sub-pixel sp3. When a user views the display panel from the right side in the first direction x, some support columns 10 block the light emitted from the second sub-pixel sp2, and some support columns 10 block the light emitted from the third sub-pixel sp3. This can further improve the color shift problem at different viewing angles and enhance the display quality.

[0042] like Figure 5As shown, within the repeating unit Y: in the three support column rows 10H arranged in the second direction y, the first support column row 10H and the third support column row 10H constitute a pair of sides of the first virtual quadrilateral 20; in the first direction x, the support columns 10 located at both ends of the three support column rows 10H constitute the other pair of sides of the first virtual quadrilateral 20; on a pair of sides of the first virtual quadrilateral 20 extending along the first direction x, two first sub-pixels sp1 are spaced between adjacent two support columns 10; on the other pair of sides of the first virtual quadrilateral 20 extending along the second direction y, a first short side 3-1 and a first long side 3-2 are spaced between adjacent two support columns 10, that is, two first virtual trapezoids 30 are spaced between adjacent two support columns 10. This arrangement allows the support columns 10 on the sides of the first virtual quadrilateral 20 to be arranged at approximately equal intervals, improving the uniformity of the arrangement of the support columns 10. Moreover, it is possible to achieve that the support columns 10 in the three support column rows 10H are all located on the parallel sides of the first virtual trapezoid 30 in which they are located; the support columns 10 arranged between two adjacent support column rows 10H are all located on the oblique sides of the first virtual trapezoid 30 in which they are located, so that the support columns 10 alternately block the light emitting from the second sub-pixel sp2 in the first direction x and the light emitting in the second direction y, and the support columns 10 also alternately block the light emitting from the third sub-pixel sp3 in the first direction x and the light emitting in the second direction y, which can improve the uniformity of the light emitting from the second sub-pixel sp2 and the third sub-pixel sp3 in different directions, and improve the color deviation problem of the display under different viewing angles. Furthermore, by further combining the fact that the oblique sides of the support columns 10 disposed between two adjacent support column rows 10H and the parallel sides of the support columns 10 within the support column row 10H do not belong to the same first virtual trapezoid 30, the difference in distance between the support columns 10 disposed between the two adjacent support column rows 10H and the two support column rows 10H in the second direction y is not too large, thereby improving the uniformity of the arrangement of the support columns 10 in the second direction y, ensuring that the support columns 10 can effectively and uniformly support the mask. Furthermore, during the vapor deposition process, when there is a certain deviation in the alignment of the mask and the display panel to be vapor deposited, it is still possible to ensure that more than half of the support columns 10 can still support the mask, ensuring that the support columns 10 effectively and uniformly support the mask.

[0043] In another embodiment, Figure 6 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Figure 6 As shown, the repeating unit Y includes three support column rows 10H arranged in the second direction y, wherein the number of support columns 10 in the three support column rows 10H is equal, namely 3; the number of support columns 10 in two adjacent support column rows 10H is 4.

[0044] Figure 6The embodiment illustrates a first virtual quadrilateral 20, wherein the four support columns 10 located at the four vertex positions of the first virtual quadrilateral 20 contribute one support column 10 to the repeating unit Y; in addition to the support columns 10 located at the vertex positions, there are four support columns 10 located on the sides of the first virtual quadrilateral 20, and these four support columns 10 contribute two support columns 10 to the repeating unit Y; and nine support columns 10 are further provided inside the first virtual quadrilateral 20. The repeating unit Y then includes a total of 12 support columns 10. In addition, the repeating unit Y includes a total of 36 first sub-pixels sp1, 18 second sub-pixels sp2, and 18 third sub-pixels sp3, and combined with the composition of the pixel P, it can be seen that Figure 6 In this embodiment, the repeating unit Y includes a total of 36 pixels. Therefore, the ratio of the number of support columns 10 to the number of pixels P in the repeating unit Y is 1:3. The display panel provided by this embodiment has a high density of support columns 10. During display panel manufacturing, the support columns 10 can uniformly and effectively support the high-precision mask used in the evaporation process for each color sub-pixel SP, ensuring uniform evaporation of each color sub-pixel SP and avoiding color shift in the display caused by poor evaporation.

[0045] like Figure 6 As shown, between two adjacent support column rows 10H: two support columns 10 are adjacent to the second sub-pixel sp2 on their left sides in the first direction x, and adjacent to the third sub-pixel sp3 on their right sides in the first direction x; the other two support columns 10 are adjacent to the third sub-pixel sp3 on their left sides in the first direction x, and adjacent to the second sub-pixel sp2 on their right sides in the first direction x. When a user views the display panel from a left perspective in the first direction x, part of the light emitted by the third sub-pixel sp3 on the right side of the support column 10 will be blocked, and part of the light emitted by the second sub-pixel sp2 on the right side of the support column 10 will also be blocked. In this embodiment, from the overall perspective of the display panel, the blocking conditions of the support columns 10 on the second sub-pixel sp2 and the third sub-pixel sp3 in different directions are basically the same, which can improve the color shift problem of the display at different viewing angles and enhance the display effect.

[0046] like Figure 6As shown, within the repeating unit Y: in the three support column rows 10H arranged in the second direction y, the first support column row 10H and the third support column row 10H constitute a pair of sides of the first virtual quadrilateral 20; in the first direction x, the support columns 10 located at both ends of the three support column rows 10H constitute the other pair of sides of the first virtual quadrilateral 20; on a pair of sides of the first virtual quadrilateral 20 extending along the first direction x, three first sub-pixels sp1 are spaced between adjacent two support columns 10; on the other pair of sides of the first virtual quadrilateral 20 extending along the second direction y, a first short side and a first long side are spaced between adjacent two support columns 10, that is, two first virtual trapezoids 30 are spaced between adjacent two support columns 10. This arrangement allows the support columns 10 on the sides of the first virtual quadrilateral 20 to be arranged at approximately equal intervals, improving the uniformity of the arrangement of the support columns 10. Moreover, it is possible to achieve that the support columns 10 in the three support column rows 10H are all located on the parallel sides of the first virtual trapezoid 30 in which they are located; the support columns 10 arranged between two adjacent support column rows 10H are all located on the oblique sides of the first virtual trapezoid 30 in which they are located, so that the support columns 10 alternately block the light emitting from the second sub-pixel sp2 in the first direction x and the light emitting in the second direction y, and the support columns 10 also alternately block the light emitting from the third sub-pixel sp3 in the first direction x and the light emitting in the second direction y, which can improve the uniformity of the light emitting from the second sub-pixel sp2 and the third sub-pixel sp3 in different directions, and improve the color deviation problem of the display under different viewing angles. Furthermore, by further combining the fact that the oblique sides of the support columns 10 between two adjacent support column rows 10H and the parallel sides of the support columns 10 within the support column row 10H do not belong to the same first virtual trapezoid 30, the spacing between the support columns 10 between two adjacent support column rows 10H and the support columns 10 within the support column row 10H is not too small, which can improve the uniformity of the arrangement of the support columns 10 in the second direction y, ensuring that the support locations 10 can effectively and uniformly support the mask. Furthermore, during the vapor deposition process, when there is a certain deviation in the alignment of the mask and the display panel to be vapor deposited, it can still be ensured that more than half of the support columns 10 can support the mask, ensuring that the support columns 10 effectively and uniformly support the mask.

[0047] In some embodiments, Figure 7 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Figure 7 As shown, the first virtual quadrilateral ( Figure 7The first virtual trapezoid 30 is divided into four second virtual quadrilaterals 50 (not shown). Two support columns 10 are provided on each side of the second virtual quadrilateral 50. Two adjacent second virtual quadrilaterals 50 share a side, and two support columns 10 are provided in each second virtual quadrilateral 50. The support columns 10 in the two diagonally opposite second virtual quadrilaterals 50 are arranged in the same manner. In addition, the support columns 10 in the three support column rows 10H are all located on the parallel sides of the first virtual trapezoid 30 in which they are located; the support columns 10 arranged between two adjacent support column rows 10H are all located on the hypotenuse of the first virtual trapezoid 30 in which they are located. Furthermore, the hypotenuse of the support columns 10 between two adjacent support column rows 10H and the parallel sides of the support columns 10 in the support column rows 10H do not belong to the same first virtual trapezoid 30. In this embodiment, a total of four support columns 10 within two adjacent second virtual quadrilaterals 50 in the first direction x or the second direction y are arranged in a "T" shape, so that the support columns 10 within the first virtual quadrilateral are more evenly arranged as a whole, thereby improving the uniformity of the arrangement of the support columns 10 in the display panel, ensuring that the support columns 10 effectively and evenly support the mask plate, improving the sub-pixel evaporation yield, and improving the display effect.

[0048] Figure 8 A cross-sectional schematic diagram of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 8 As shown, the display panel includes a substrate 60 and a pixel definition layer 70 located on one side of the substrate 60. The pixel definition layer 70 has a plurality of openings K, one opening K corresponding to one sub-pixel sp; the pixel definition layer 70 is used to space adjacent sub-pixels sp. The sub-pixel sp includes a stacked first electrode 81, a light-emitting layer 82, and a second electrode 83. The display panel also includes a driving layer 90, which is located between the sub-pixel sp and the substrate 60. A pixel circuit 91 is provided in the driving layer 90. The pixel circuit 91 is coupled to the sub-pixel sp and is used to drive the sub-pixel sp to emit light. An encapsulation structure 61 is also provided on the side of the sub-pixel sp away from the substrate 60. The encapsulation structure 61 is used to isolate water and oxygen to ensure the service life of the sub-pixel sp. Among them, the support column 10 is located on the side of the pixel definition layer 70 away from the substrate 60. The distance between the support column 10 and the opening K closest to it is d, and d≥4μm. During display panel fabrication, a pixel definition layer 70 is first fabricated. The pixel definition layer 70 has multiple openings K, and the sidewalls of the openings K are the edges of the pixel definition layer 70. Support pillars 10 are then fabricated on top of the pixel definition layer 70. In this embodiment, the distance between the support pillars 10 and the openings K in the pixel definition layer 70 is set to be no less than 4 μm, ensuring that the distance between the support pillars 10 and the openings K is not too small. This ensures that even if there is a certain misalignment between the mask and the display panel to be deposited during the evaporation process, the support pillars 10 can still support the mask, ensuring relatively uniform stress on the mask as a whole and ensuring the evaporation yield.
