It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a schematic top view of a display panel according to an embodiment of the present invention, and fig. 2 is a schematic cross-sectional view along direction AA' in fig. 1, as shown in fig. 1 and fig. 2, a plurality of sub-pixel units 1, each of the plurality of sub-pixel units 1 includes a white sub-pixel unit 11, a first sub-pixel unit 12, a second sub-pixel unit 13, and a third sub-pixel unit 14; in the row direction X, the width H1 of the corresponding region of the white sub-pixel unit 11 is smaller than the widths H2 of the corresponding regions of the first sub-pixel unit 12, the second sub-pixel unit 13 and the third sub-pixel unit 14; each sub-pixel cell 1 comprises a thin film transistor (not shown) comprising a drain electrode 2; in the row direction X, a region between two adjacent sub-pixel units 1 includes a first region 3 and a second region 4, where the first region 3 is a region between the drains 2 corresponding to any two of the first sub-pixel unit 12, the second sub-pixel unit 13, and the third sub-pixel unit 14; the second region 4 is a region between the drain 2 corresponding to any one of the first sub-pixel unit 12, the second sub-pixel unit 13, and the third sub-pixel unit 14 and the drain 2 corresponding to the white sub-pixel unit 11; the display panel comprises a plurality of support columns 5, wherein the plurality of support columns 5 comprise a first support column 51 and a second support column 52, the height of the first support column 51 is larger than that of the second support column 52 in the direction perpendicular to the display panel, and the orthographic projection of any first support column 51 on the display panel at least partially overlaps with the first area 3.
Specifically, as shown in fig. 1, the display panel includes a white sub-pixel unit 11, a first sub-pixel unit 12, a second sub-pixel unit 13, and a third sub-pixel unit 14, and since the white sub-pixel unit 11 has a high transmittance, the brightness of the display panel can be improved after the above design is adopted; moreover, in the row direction X, the width H1 of the area corresponding to the white sub-pixel unit 11 is smaller than the width H2 of the area corresponding to the first sub-pixel unit 12, the second sub-pixel unit 13, and the third sub-pixel unit 14, so that the screen occupation ratio of the white sub-pixel unit 11 can be reduced after the design is adopted, thereby being beneficial to reducing the influence of the white sub-pixel unit 11 on the display effect of the display panel and improving the resolution of the display panel.
As shown in fig. 2, the display panel further includes an array substrate 6, a planarization layer 7 on the array substrate 6 (other film layers are also disposed on the array substrate 6, other film layers are not shown), where the planarization layer 7 is used to make the array substrate 6 have better planarity, a support pillar on the side of the planarization layer 7 away from the substrate, optionally, a first support pillar 51 is in contact with the planarization layer 7, a second support pillar 52 is not in contact with the planarization layer 7, and a cover plate 8 on the side of the support pillar away from the array substrate 6, optionally, both the first support pillar 51 and the second support pillar 52 are in contact with the cover plate 8, and with the above arrangement, the first support pillar 51 can function as a main support, and the second support pillar 52 can function as an auxiliary support, that is, when the display panel is not pressed, the first support pillar 51 supports the display panel, so that the display panel can maintain its original shape, after the display panel is pressed, the display panel deforms, and the second support column 52 and the first support column 51 can support the display panel at the same time, so that internal devices in the display panel can be protected.
As shown in fig. 2, the planarization layer 7 includes the via hole 71 corresponding to the drain electrode 2, as shown in fig. 1 and 2, since the width H1 of the region corresponding to the white sub-pixel unit 11 is smaller than the widths H2 of the regions corresponding to the first sub-pixel unit 12, the second sub-pixel unit 13, and the third sub-pixel unit 14 in the row direction X, the distance between the drain electrode 2 corresponding to the white sub-pixel unit 11 and the drain electrode 2 corresponding to the third sub-pixel unit 14 is smaller than the distance between the drain electrode 2 corresponding to the third sub-pixel unit 14 and the drain electrode 2 corresponding to the second sub-pixel unit 13, and the distance between the via hole 711 corresponding to the drain electrode 2 of the third sub-pixel unit 14 and the via hole 712 corresponding to the drain electrode 2 of the white sub-pixel unit 11 is smaller than the distance between the via hole 713 corresponding to the drain electrode 2 of the second sub-pixel unit 13 and the via hole 711 corresponding to the drain electrode 2 of the third sub-pixel unit 14, therefore, compared with the prior art, when the first support column 51 is disposed in the first region 3 in the embodiment of the present invention, the contact area between the first support column 51 and the planarization layer 7 is relatively large, that is, the standing area of the first support column 51 is relatively large, so that the first support column 51 stands stably, and the support effect of the first support column 51 is further improved.
As shown in fig. 1, the drain electrode 2 is electrically connected to an electrode (not shown) in the corresponding sub-pixel unit 1, so that a data signal in a data line (not shown) is transmitted to the electrode through the drain electrode 2, thereby causing the corresponding sub-pixel unit 1 to emit light.
It should be noted that the orthographic projection area of the first support column 51 is larger than that of the second support column 52, and since the distance between the drain electrodes 2 corresponding to the position of the first region 3 is larger than that between the drain electrodes 2 corresponding to the position of the second region 4, the first support column 51 needs to be disposed at the position of the first region 3 to reduce the influence of the first support column 51 on the internal devices in the sub-pixel unit 1.
Alternatively, as shown in fig. 1, in two adjacent rows of sub-pixel units, one row of sub-pixel units is sequentially arranged in the order of the first sub-pixel unit 12, the second sub-pixel unit 13, the third sub-pixel unit 14, and the white sub-pixel unit 11, and the other row of sub-pixel units is sequentially arranged in the order of the third sub-pixel unit 14, the white sub-pixel unit 11, the first sub-pixel unit 12, and the second sub-pixel unit 13.

It should be noted that the arrangement of the sub-pixel units is merely an example, and the arrangement of the sub-pixel units may also be set according to actual requirements, and the specific arrangement is not specifically limited herein.
Optionally, fig. 3 is a schematic top view of another display panel according to an embodiment of the present invention, and as shown in fig. 3, an orthographic projection of the first support pillar 51 on the display panel at least partially overlaps with regions between the drains 2 corresponding to the second sub-pixel units 13 and the third sub-pixel units 14 in the same row.
Specifically, as shown in fig. 3, after the first support column 51 is disposed at the above position, the overlapping area between the first support column 51 and the white sub-pixel unit 11 can be reduced, and the proportion of the light-transmitting area of the white sub-pixel unit 11 occupied by the first support column 51 can be reduced, thereby being beneficial to improving the light transmittance of the display panel.

It should be noted that, according to actual needs, a part of the second supporting columns 52 may be disposed in the first area 3, and another part may be disposed in the second area 4, or all of the second supporting columns 52 may be disposed in the first area 3, and the specific situation is set according to actual needs, and is not limited specifically here.
