[0062] Figure 1 FIG. 1 shows a schematic top view of a display panel in an embodiment of the present application. Figure 2 Shows Figure 1 The cross-sectional view of the display panel at AA is shown in FIG. Figure 3 Shows Figure 1 A schematic cross-sectional view of a display panel taken at BB is shown.

[0063] See also Figure 1-Figure 3 An embodiment of the present application provides a display panel, which includes a substrate 100, a plurality of support columns 200 and a plurality of sub-pixels 300.

[0064] A plurality of support columns 200 are arranged at intervals on the substrate 100, a plurality of sub-pixels 300 are arranged at intervals on the substrate 100, and support columns 300 are arranged between adjacent sub-pixels 300, so as to facilitate the use of a plurality of support columns 200 to support a fine metal mask plate (FMM) so as to form a plurality of sub-pixels 300 by evaporating light-emitting materials on the substrate 100.

[0065] The plurality of sub-pixels 300 include a first sub-pixel 310 and a second sub-pixel 320 , and the plurality of support columns 200 include a first support column 210 adjacent to the first sub-pixel 310 , and a second support column 220 adjacent to the second sub-pixel 320 .

[0066] The dimension of the first support column 210 along the thickness direction of the substrate 100 is H1, and the dimension of the second support column 220 along the thickness direction of the substrate 100 is H2. H1 and H2 satisfy the following condition: the ratio of H1 to H2 is 0.95-1.05.

[0067] In the present application, the first support column 210 adjacent to the first sub-pixel 310 and the second support column 220 adjacent to the second sub-pixel 320 are designed so that the ratio between the height of the first support column 210 (i.e., H1) and the height of the second support column 220 (i.e., H2) is set to 0.95-1.05, that is, the height of the first support column 210 tends to be equal to the height of the second support column 220. In this way, the height difference of the support column 200 between different sub-pixels 300 can be reduced, and the probability of unevenness in the area where the first sub-pixel 310 and the second sub-pixel 320 are located due to the first support column 210 and the second support column 220 can be reduced, thereby effectively improving the Newton ring problem, which is beneficial to improving the picture quality of the display panel.

[0068] In some embodiments, the ratio of H1 to H2 is 1.

[0069] It should be noted that the manufacturing process may result in a slight difference between the height of the first support column 210 and the height of the second support column 220 , and it can also be considered that the height of the first support column 210 is equal to the height of the second support column 220 .

[0070] Since the height of the first support column 210 is equal to the height of the second support column 220, the probability of unevenness in the area where the first sub-pixel 310 and the second sub-pixel 320 are located due to the first support column 210 and the second support column 220 can be further reduced, thereby effectively improving the Newton ring problem, which is beneficial to improving the picture quality of the display panel.

[0071] In some embodiments, H1 and H2 are both greater than or equal to a preset value.

[0072] H1 and H2 are set large enough, and a plurality of support pillars 200 are set between the substrate 100 and the packaging layer 400. This helps to reduce the difference between the thickness of one side of the substrate 100 where the first signal line 111 is set and the thickness of the other side of the substrate 100, thereby helping to improve the Newton ring problem at the upper and lower frames.

[0073] In some embodiments, a first signal line 111 is disposed on the substrate 100 , and a thickness of the first signal line 111 is D1 , and the preset value is 5*D1-10*D1.

[0074] Illustratively, the preset value is 5*D1, 6*D1, 7*D1, 8*D1, 9*D1 or 10*D1.

[0075] That is to say, H1 and H2 are at least greater than or equal to 5*D1. In this way, the height of the first support column 210 and the height of the second support column 220 are much greater than the thickness of the first signal line 111, which is beneficial to reduce the difference between the thickness of one side of the substrate 100 where the first signal line 111 is set and the thickness of the other side of the substrate 100, and thus helps to improve the Newton ring problem at the upper and lower frames.

[0076] In some embodiments, the size relationship among D1, H1 and H2 satisfies the following conditions: H1>7*D1, and / or, H2>7*D1.

[0077] For example, the thickness of the first signal line 111 is 5 micrometers, and H1 and H2 are greater than 3.5 micrometers. For example, H1 and H2 are both 4 micrometers, 5 micrometers, or 6 micrometers.

[0078] In this way, the height of the first support column 210 and the height of the second support column 220 are both much greater than the thickness of the first signal line 111, which is beneficial to reducing the difference between the thickness of one side of the substrate 100 where the first signal line 111 is set and the thickness of the other side of the substrate 100, and further helps to improve the Newton ring problem at the upper and lower frames.

[0079] In some embodiments, the sub-pixel 300 includes a first electrode 301 , a light-emitting portion 302 , and a second electrode 303 stacked on the substrate 100 in a direction away from the substrate 100 , and the first signal line 111 is electrically connected to the first electrode 301 or the second electrode 303 .

[0080] The first signal line 111 may be a VDD signal line, and the first signal line 111 is electrically connected to the first electrode 301. Alternatively, the first signal line 111 may be a VSS signal line, and the first signal line 111 is electrically connected to the second electrode 303.

[0081] In this way, while providing the corresponding sub-pixel 300 with the corresponding voltage signal through the first signal line 111, the difference between the thickness of one side of the substrate 100 where the first signal line 111 is set and the thickness of the other side of the substrate 100 can be reduced by using a plurality of support pillars 200 with a higher height, thereby helping to improve the Newton ring problem at the upper and lower frames.

[0082] In some embodiments, a plurality of pixel openings 121 are provided on the substrate 100, the plurality of pixel openings 121 include a first pixel opening 1211 corresponding to the first sub-pixel 310, and a second pixel opening 1212 corresponding to the second sub-pixel 320, the orthographic projection of the first support column 210 on the substrate 100 and the orthographic projection of the adjacent first pixel opening 1211 on the substrate 100 are spaced J1, and the orthographic projection of the second support column 220 on the substrate 100 and the orthographic projection of the adjacent second pixel opening 1212 on the substrate 100 are spaced J2. J1 and J2 satisfy the following condition: the ratio of J1 to J2 is 0.95-1.05.

[0083] Since the ratio of J1 to J2 is 0.95-1.05, the distance between the orthographic projection of the first support column 210 on the substrate 100 and the orthographic projection of the adjacent first pixel opening 1211 on the substrate 100 is approximately equal to the distance between the orthographic projection of the second support column 220 on the substrate 100 and the orthographic projection of the adjacent second pixel opening 1212 on the substrate 100. This indicates that in the process of manufacturing the first support column 210 and the second support column 220, the distance between the support material corresponding to the first support column 210 and the adjacent first pixel opening 1211 can also be approximately equal to the distance between the support material corresponding to the second support column 220 and the adjacent second pixel opening 1212. As a result, the flow ranges of the support material corresponding to the first support column 210 and the support material corresponding to the second support column 220 on the substrate 100 are roughly equal (the support material corresponding to the first support column 210 will flow toward the edge of the adjacent first pixel opening 1211 before solidification, and form the first support column 210 after solidification; similarly, the support material corresponding to the second support column 220 will flow toward the edge of the adjacent second pixel opening 1212 before solidification, and form the second support column 220 after solidification), which makes it less likely that the height of some support columns 200 is too low due to the excessive flow range of their support materials, which is conducive to making the height of the first support column 210 tend to be equal to the height of the second support column 220.

[0084] In some embodiments, the ratio of J1 to J2 is 1.

[0085] In this way, it is more conducive to making the height of the first support column 210 tend to be equal to the height of the second support column 220, thereby reducing the probability of unevenness in the area where the first sub-pixel 310 and the second sub-pixel 320 are located due to the first support column 210 and the second support column 220, thereby effectively improving the Newton ring problem, which is beneficial to improving the picture quality of the display panel.

[0086] In some embodiments, 4 μm≤J1≤6 μm, and / or, 4 μm≤J2≤6 μm.

[0087] Illustratively, J1 is 4 μm, 5 μm or 6 μm, and J2 is 4 μm, 5 μm or 6 μm.

[0088] In this way, it is less likely that the height of the first support column 210 is too low due to the excessive flow range of its supporting material, and it is also less likely that the height of the second support column 220 is too low due to the excessive flow range of its supporting material. This is conducive to the height of the first support column 210 tending to be equal to the height of the second support column 220.

[0089] In some embodiments, the plurality of sub-pixels 300 further include a third sub-pixel 330, the plurality of pixel openings 121 include a third pixel opening 1213 corresponding to the third sub-pixel 330, the plurality of support columns 200 further include a third support column 230 adjacent to the third sub-pixel 330, and the orthographic projection of the third support column 230 on the substrate 100 and the orthographic projection of the adjacent third pixel opening 1213 on the substrate 100 are spaced J3 apart. J1 and J3 satisfy the following condition: the ratio of J1 to J3 is 0.95-1.05.

[0090] Since the ratio of J1 to J3 is 0.95-1.05, the distance between the orthographic projection of the first support column 210 on the substrate 100 and the orthographic projection of the adjacent first pixel opening 1211 on the substrate 100 is approximately equal to the distance between the orthographic projection of the third support column 230 on the substrate 100 and the orthographic projection of the adjacent third pixel opening 1213 on the substrate 100. This indicates that in the process of manufacturing the first support column 210 and the third support column 230, the distance between the support material corresponding to the first support column 210 and the adjacent first pixel opening 1211 can also be approximately equal to the distance between the support material corresponding to the third support column 230 and the adjacent third pixel opening 1213, thereby making the flow range of the support material corresponding to the first support column 210 and the support material corresponding to the third support column 230 on the substrate 100 approximately equal, and it is not easy for some support columns 200 to have too low a height due to the excessive flow range of their support materials, which is conducive to the height of the first support column 210 tending to be equal to the height of the third support column 230.

[0091] In some embodiments, the ratio of J1 to J3 is 1.

[0092] In this way, it is more conducive to making the height of the first support column 210 tend to be equal to the height of the third support column 230, thereby reducing the probability of unevenness in the area where the first sub-pixel 310 and the third sub-pixel 330 are located due to the first support column 210 and the third support column 230, thereby effectively improving the Newton ring problem, and thus helping to improve the picture quality of the display panel.

[0093] Optionally, 4μm≤J3≤6μm.

[0094] Illustratively, J3 is 4 μm, 5 μm or 6 μm.

[0095] In this way, it is less likely that the height of the third support column 230 is too low due to the excessive flow range of the support material of the third support column 230 , which is conducive to the height of the third support column 230 being equal to the height of the first support column 210 .

[0096] In some embodiments, a dimension of the third support column 230 along the thickness direction of the substrate 100 is H3, and H1 and H3 satisfy the following condition: a ratio of H1 to H3 is 0.95-1.05.

[0097] Optionally, the ratio of H1 to H3 is 1.

[0098] Since the height of the first support column 210 (i.e., H1) tends to be equal to the height of the third support column 230 (i.e., H3), the probability of unevenness in the area where the first sub-pixel 310 and the third sub-pixel 330 are located due to the first support column 210 and the third support column 230 can be reduced, thereby effectively improving the Newton ring problem, which is beneficial to improving the picture quality of the display panel.

[0099] In some embodiments, the size relationship between D1 and H3 satisfies the following condition: 5*D1≤H3≤10*D1.

[0100] Illustratively, H3 is 5*D1, 6*D1, 7*D1, 8*D1, 9*D1 or 10*D1.

[0101] That is to say, H3 is at least greater than or equal to 5*D1. In this way, the height of the third support column 230 is much greater than the thickness of the first signal line 111, which is beneficial to reduce the difference between the thickness of one side of the substrate 100 where the first signal line 111 is set and the thickness of the other side of the substrate 100, and thus helps to improve the Newton ring problem at the upper and lower frames.

[0102] Optionally, H3>7*D1.

[0103] For example, the thickness of the first signal line 111 is 5 micrometers, and H3 is greater than 3.5 micrometers, for example, H3 is 4 micrometers, 5 micrometers, or 6 micrometers.

[0104] Thus, the height of the third support column 230 is much greater than the thickness of the first signal line 111, which helps to reduce the difference between the thickness of one side of the substrate 100 where the first signal line 111 is set and the thickness of the other side of the substrate 100, thereby helping to improve the Newton ring problem at the upper and lower frames.

[0105] In some embodiments, the first sub-pixel 310 and the third sub-pixel 330 are aligned along the first direction F 1 The plurality of second sub-pixels 320 in the same column are arranged at intervals along the first direction F 1 The first sub-pixel 310 and the second sub-pixel 320 are arranged at intervals along the first direction F 1 The second direction of intersection F 2The first support column 210 is disposed between the first sub-pixel 310 and the adjacent third sub-pixel 330 , and the second support column 220 is disposed between two adjacent second sub-pixels 320 .

[0106] Optionally, the first sub-pixel 310 and the third sub-pixel 330 in the same column are arranged along the first direction F 1 The third support column 230 is disposed between the third sub-pixel 330 and the adjacent first sub-pixel 310 .

[0107] Thus, the first support column 210 and the second support column 220 can be designed according to the positions of the first sub-pixel 310, the second sub-pixel 320 and the third sub-pixel 330 along the first direction F. 1 and the second direction F 2 The size of the first support column 210 can reasonably utilize the occupied area of ​​the substrate 100, and it is also convenient to make the height of the first support column 210 tend to be equal to the height of the second support column 220.

[0108] In some embodiments, the second support column 220 is arranged along the first direction F 1 Extension settings.

[0109] Since the distance between two adjacent second sub-pixels 320 is relatively large, the second support column 220 is arranged along the first direction F 1 The extended setting is beneficial to reducing the distance between the orthographic projection of the second support column 220 on the substrate 100 and the orthographic projection of the adjacent second pixel opening 1212 on the substrate 100, thereby avoiding that the flow range of the supporting material corresponding to the second support column 220 on the substrate 100 is too large, which is beneficial to increasing the height of the second support column 220, so that the height of the second support column 220 can tend to be equal to the height of the first support column 210.

[0110] In some embodiments, the first support column 210 is arranged along the second direction F 2 Extension settings.

[0111] Since the distance between the first sub-pixel 310 and the adjacent third sub-pixel 330 is small, the first support column 210 is arranged along the first direction F 1 The second direction of intersection F 2The extended setting is conducive to the rational use of the space between the first sub-pixel 310 and the adjacent third sub-pixel 330, and is also conducive to making the distance between the orthographic projection of the first support column 210 on the substrate 100 and the orthographic projection of the adjacent first pixel opening 1211 on the substrate 100 roughly equal to the distance between the orthographic projection of the second support column 220 on the substrate 100 and the orthographic projection of the adjacent second pixel opening 1212 on the substrate 100, which is conducive to making the height of the first support column 210 tend to be equal to the height of the second support column 220.

[0112] Similarly, the third support column 230 can also be moved along the second direction F 2 Extension settings.

[0113] In some embodiments, the first support column 210 is arranged along the first direction F 1 is smaller than the size of the second support column 220 along the second direction F 2 size.

[0114] The second support column 220 extends along the second direction F 2 The larger width of the size is beneficial to increasing the bottom area of ​​the second support column 220, thereby facilitating the formation of a thicker support material on the substrate 100, and also beneficial to increasing the height of the second support column 220, and more beneficial to making the height of the second support column 220 tend to be equal to the height of the first support column 210.

[0115] In some embodiments, Figure 1-Figure 4 As shown, a plurality of the sub-pixels 300 are arranged to form a plurality of first repeating units 300a, each of the first repeating units 300a includes a first sub-pixel 310, a second sub-pixel 320 and a third sub-pixel 330; the first sub-pixel 310 and the third sub-pixel 330 are arranged in one column, and the second sub-pixel 320 is arranged in another adjacent column. The first supporting column 210 is disposed between the first sub-pixel 310 and the adjacent third sub-pixel 330, and the second supporting column 220 is disposed between two adjacent second sub-pixels 320.

[0116] Optionally, the first sub-pixels 310 and the third sub-pixels 330 in the same column are alternately arranged, and the third supporting column 230 is arranged between the third sub-pixel 330 and the adjacent first sub-pixel 310 .

[0117] In other embodiments, Figure 5-Figure 6As shown, a plurality of the sub-pixels 300 are arranged to form a plurality of second repeating units, each of the second repeating units includes two of the first sub-pixels 310, one of the second sub-pixels 320, and two of the third sub-pixels 330; the first sub-pixels 310 and the third sub-pixels 330 are arranged in one column, and the second sub-pixels 320 are arranged in another adjacent column. The first supporting column 210 is disposed between the first sub-pixel 310 and the adjacent third sub-pixel 330, and the second supporting column 220 is disposed between two adjacent second sub-pixels 320.

[0118] Optionally, the first sub-pixels 310 and the third sub-pixels 330 in the same column are alternately arranged, and the third supporting column 230 is arranged between the third sub-pixel 330 and the adjacent first sub-pixel 310 .

[0119] Optionally, the first sub-pixel 310 is one of a red sub-pixel, a green sub-pixel, and a blue sub-pixel, the second sub-pixel 320 is another of the red sub-pixel, the green sub-pixel, and the blue sub-pixel, and the third sub-pixel 330 is another of the red sub-pixel, the green sub-pixel, and the blue sub-pixel. For example, the first sub-pixel 310 is a red sub-pixel, the second sub-pixel 320 is a blue sub-pixel, and the third sub-pixel 330 is a green sub-pixel.

[0120] In this way, the regular arrangement of the plurality of first repeating units 300a and the regular arrangement of the plurality of second repeating units are beneficial to improving the aperture ratio of the display panel. In addition, the second support column 220 can be designed accordingly in combination with the large spacing between two adjacent second sub-pixels 320. For example, the second support column 220 can be designed to have a larger spacing between the two adjacent second sub-pixels 320. 1 The size of the second support column 220 is conducive to increasing the height of the second support column 220, so that the height of the second support column 220 can be close to the height of the first support column 210.

[0121] In some embodiments, the substrate 100 includes an array substrate 110 and a plurality of first electrodes 301 disposed on the array substrate 110. The substrate 100 also includes a pixel definition layer 120 disposed on the array substrate 110. The pixel definition layer 120 is provided with a plurality of pixel openings 121 for at least partially exposing the first electrodes 301. The light-emitting portion 302 and the second electrode 303 are stacked on the corresponding first electrode 301 to form a plurality of sub-pixels 300.

[0122] The display panel has a display area 101 and a frame area 102 adjacent to the display area 101 . The first signal line 111 is located in the frame area 102 . Specifically, the frame area 102 includes an upper frame area 1021 and a lower frame area 1022 . The first signal line 111 is located in the lower frame area 1022 .

[0123] An embodiment of the present application provides a display device 10, comprising a display panel of any of the above embodiments.

[0124] In some embodiments, Figure 7 As shown, the display device 10 further includes an encapsulation layer 400 and a cover plate 500 . The encapsulation layer 400 is disposed on a side of the support column 200 away from the substrate 100 , and is bonded between the substrate 100 and the cover plate 500 .

[0125] Specifically, the packaging layer 400 is packaging glue.

[0126] Since the height of the first support column 210 tends to be equal to the height of the second support column 220, and H1 and H2 are both greater than or equal to the preset value, the difference between the thickness of one side of the substrate 100 where the first signal line 111 is set and the thickness of the other side of the substrate 100 can be reduced, which is beneficial to improve the Newton ring problem at the upper and lower frames.
