the application provides a display panel, which comprises a plurality of repeated units 10, wherein each repeated unit 10 comprises two first sub-pixels 11, two second sub-pixels 12 and four third sub-pixels 13; wherein, two first sub-pixels 11 and two second sub-pixels 12 are respectively located at two ends of a diagonal line of a first virtual rectangle 21, a third sub-pixel 13 is located inside the first virtual rectangle 21, four third sub-pixels 13 are located at the top of a second virtual rectangle 22, and a first sub-pixel 11 is located inside the second virtual rectangle 22; in a repeating unit 10, a trimming edge 15 is disposed at an edge of at least one of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13;

when one of the third sub-pixels 13 is provided with a trimming 15, the distance between the one third sub-pixel 13 provided with the trimming 15 and the adjacent other third sub-pixel 13 is larger than the distance between the other two adjacent third sub-pixels 13 not provided with the trimming 15;

and the display panel further comprises a support column 14, wherein the support column 14 is arranged on the edge where the first virtual rectangle 21 or the second virtual rectangle 22 intersects with the trimming 15.

By arranging two first sub-pixels 11 and two second sub-pixels 12 at two ends of a diagonal line of a first virtual rectangle 21, a third sub-pixel 13 inside the first virtual rectangle 21, and four third sub-pixels 13 at the top of a second virtual rectangle 22, and a first sub-pixel 11 inside the second virtual rectangle 22, resolution of the display panel is not reduced, and a trimming edge 15 is provided at an edge of at least one sub-pixel of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13, so that a distance between two sub-pixels on edges of the first virtual rectangle 21 or the second virtual rectangle 22 intersecting with the trimming edge 15 is increased, and when the support column 14 is arranged on the edge, a placement space of the support column 14 is larger, thereby reducing scratch risk of the support column 14.

In this application, referring to fig. 1, the display panel includes a display area AA and a non-display area NA located at the periphery of the display area AA. The display area AA is provided with a plurality of repeating units 10 distributed in an array, and the repeating units 10 may include a plurality of sub-pixels. The repeating units 10 may be arranged in the first direction Y and the second direction X of the display panel. For example, the first direction Y may be a vertical direction and the second direction X may be a horizontal direction. The first direction Y and the second direction X may be other directions, which is not limited in this application. In the present application, the first direction Y is taken as a vertical direction, and the second direction X is taken as a horizontal direction as an example.

The repeating unit 10 includes two first sub-pixels 11, two second sub-pixels 12, and four third sub-pixels 13. The first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 may be sub-pixels of different colors, for example, the first sub-pixel 11 may be a blue sub-pixel, the second sub-pixel 12 may be a red sub-pixel, and the third sub-pixel 13 may be a green sub-pixel. The colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 may be interchanged, which is not limited in this application.

As shown in fig. 2, fig. 2 is a cross-sectional view of a display area AA of the display panel. The display panel includes an array substrate 33, and a light emitting unit 37 disposed on the array substrate 33, and one subpixel includes one light emitting unit 37. The light emitting unit 37 includes an anode electrode 35, a light emitting material layer 36, and a cathode electrode layer (not shown), and the light emitting material layers 36 of the sub-pixels of different colors may emit light of different colors.

The array substrate 33 may include a plurality of thin film transistors 34 distributed in an array, and the thin film transistors 34 are used to provide driving to the light emitting units 37. In some embodiments, the drain electrode of the thin film transistor 34 is electrically connected to the anode electrode 35 of the light emitting unit 37 for providing an electrical signal to the light emitting unit 37 to control the light emitting unit 37 to emit light. One structure of the thin film transistor 34 is shown in fig. 2, and the thin film transistor 34 in fig. 2 is a double gate transistor, but is not limited thereto. For example, the thin film transistor 34 may be a single gate transistor, and the gate of the thin film transistor 34 may be a top gate or a bottom gate. The structure of the thin film transistor 34 does not affect the achievement of the effect of the present application.

With continued reference to fig. 2, the display panel may include a pixel defining layer 31 having pixel openings defining a first sub-pixel 11, a second sub-pixel 12, and a third sub-pixel 13. That is, the light emitting material layer 36 of the light emitting unit 37 may be formed in the pixel opening, and the cathode layer covers the light emitting material layer 36. It should be noted that the light emitting material layers 36 of two adjacent light emitting units 37 are different and discontinuous, so that the light emission of one light emitting unit 37 can be controlled individually. The cathode layer may be continuously coated on the light emitting material layer 36 and the pixel defining layer 31. In the light emitting unit 37, a voltage is applied to the anode 35 and the cathode layer, the anode 35 is for providing holes, the cathode is for providing electrons, and the holes and electrons are recombined in the light emitting material layer 36 to emit light.

With continued reference to fig. 2, the support pillars 14 are located on the pixel defining layer 31, and the support pillars 14 are located between two adjacent pixel openings. The luminescent material layer 36 may be fabricated using an evaporation process. When the evaporation process is used to manufacture the luminescent material layer 36, a photomask is disposed on a side of the luminescent material layer 36 away from the array substrate 33, an opening is disposed on the photomask corresponding to the pixel opening, and luminescent material can enter the pixel opening from the opening of the photomask and form the luminescent material layer 36 in the pixel opening. The support posts 14 may be used to support the mask to maintain the spacing between the mask and the pixel openings. The mask is typically a metal material and the mask openings are relatively sharp, which can easily cause the support posts 14 to be scratched by the mask openings when the mask openings are aligned with the pixel openings. It should be appreciated that the number and distribution of support columns 14 may be adjusted as desired to meet the support requirements of the reticle.

The support columns 14 can be in one-to-one correspondence with the trimming edges 15, so that the influence of the trimming edges 15 on the opening ratio of the display panel is reduced as much as possible under the condition of reducing the scratch risk of the support columns 14. Of course, part of the support columns 14 may be disposed between two adjacent sub-pixels without the trimming 15, so as to reduce the influence on the aperture ratio of the display panel. The present application is not limited in this regard.

Accordingly, the number of cut edges 15 in a repeating unit can be adjusted as needed to meet the support requirements of the support column 14. The number of cut edges 15 may be less than or equal to the number of support posts 14 for a better display. But is not limited thereto.

Referring to fig. 3 to 6, the pattern shape of each sub-pixel corresponds to the front projection of the light emitting material layer 36 in fig. 2 on the display plane. On the display plane, two first sub-pixels 11 and two second sub-pixels 12 are respectively located at two ends of a diagonal line of a first virtual rectangle 21, one third sub-pixel 13 is located inside the first virtual rectangle 21, and four third sub-pixels 13 are located at vertices of a second virtual rectangle 22, and one first sub-pixel 11 is located inside the second virtual rectangle 22. The first virtual rectangle 21 and the second virtual rectangle 22 partially overlap, and the third sub-pixel 13 located inside the first virtual rectangle 21 is located at the vertex of the second virtual rectangle 22 at the same time, and the first sub-pixel 11 located inside the second virtual rectangle 22 is located at the vertex of the first virtual rectangle 21 at the same time. Through the arrangement, the arrangement space of the sub-pixels of the display panel can be more reasonably utilized, and the interval between the sub-pixels is more optimal. Meanwhile, SPR (Sub Pixel Rendering ) may be adapted to achieve a high PPI (Pixel Per Inch) display effect.

In some embodiments, the first virtual rectangle 21 and the second virtual rectangle 22 may be square, so that the sub-pixel arrangement space utilization of the display panel is further improved, and the display effect of the display panel is further improved.

In some embodiments, two first sub-pixels 11 and two second sub-pixels 12 are located at both ends of a diagonal line of one first virtual rectangle 21, respectively, that is, two first sub-pixels 11 are located at both ends of one diagonal line of the first virtual rectangle 21, and two second sub-pixels 12 are located at both ends of the other diagonal line of the first virtual rectangle 21. I.e. on the sides of the first virtual rectangle 21, two first sub-pixels 11 and two second sub-pixels 12 are alternately arranged.

With continued reference to fig. 3 to 6, in a repeating unit 10, a trimming edge 15 is disposed at an edge of at least one of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13. The trimming 15 means cutting out a partial region at the edge of the sub-pixel so that the remaining sub-pixel has a smaller area than the original sub-pixel. That is, after the first sub-pixel 11 is provided with the trimming 15, the area of the sub-pixel is smaller than the area of the first sub-pixel 11 without the trimming 15. The area of the sub-pixel refers to the area of the orthographic projection of the luminescent material layer 36 in the pixel opening on the display plane. For convenience of description, as shown in fig. 3, 5 and 6, one of the sides of the first virtual rectangle 21 is named as a first side 211 in this application.

When one of the third sub-pixels 13 is provided with the trimming 15, as shown in fig. 3, the distance between the third sub-pixel 13 provided with the trimming 15 and the adjacent third sub-pixel 13 is larger than the distance between any two other third sub-pixels 13 not provided with the trimming 15 among any two adjacent third sub-pixels 13.

As shown in fig. 5, when one of the first sub-pixels 11 is provided with the trimming 15, the pitch between the first sub-pixel 11 and the second sub-pixel 12 provided with the trimming 15 is larger than the pitch between the first sub-pixel 11 and the second sub-pixel 12 provided with no trimming 15, among any two adjacent first sub-pixel 11 and second sub-pixel 12.

As shown in fig. 6, when one of the second sub-pixels 12 is provided with the trimming 15, the pitch between the second sub-pixel 12 provided with the trimming 15 and the first sub-pixel 11 is larger than the pitch between the first sub-pixel 11 and the second sub-pixel 12 provided with no trimming 15 in any two adjacent first sub-pixel 11 and second sub-pixel 12.

In the embodiments of the present application, the pitch refers to the distance of the boundary of two adjacent sub-pixels that are close to each other, rather than the distance of the center of the sub-pixel. When the borders of the sub-pixels close to each other are parallel, the distance between the two borders is the distance between the two sub-pixels. When the boundaries of the sub-pixels close to each other are not parallel, the minimum distance between the two boundaries is the distance between the two sub-pixels.

As shown in fig. 4, fig. 4 shows a partial sub-pixel in fig. 3, and the effect of providing the trimming 15 will be described by taking the trimming 15 provided on the third sub-pixel 13 as an example. The left side of the arrow shows the original third sub-pixel 13 without the cut edge 15, with the support column 14 located between adjacent sub-pixels. At this time, in the first direction Y, the first pitch of the adjacent two third sub-pixels 13 is S1. The right side of the arrow shows that after the trimming 15 is provided on one of the third sub-pixels 13, the second spacing between two adjacent third sub-pixels 13 in the first direction Y is S2. The edge of the third sub-pixel 13 is retracted by a certain distance towards the inner side of the third sub-pixel 13 due to the existence of the trimming 15, so that the second distance S2 is larger than the first distance S1, the placement space of the support column 14 is increased, and the risk that the support column 14 is scratched by the opening of the photomask is reduced.

The following structural embodiments describe the technical solutions of the present application.

Referring to fig. 3, in one embodiment, one of the four third sub-pixels 13 is provided with a trimming edge 15, the centers of the two first sub-pixels 11 are located at the vertex of the first virtual rectangle 21, the centers of the two second sub-pixels 12 are located at the vertex of the first virtual rectangle 21, the center of gravity of the third sub-pixel 13 provided with the trimming edge 15 is not overlapped with the vertex of the second virtual rectangle 22, and the centers of the other three third sub-pixels 13 are overlapped with the vertex of the second virtual rectangle 22.

Since the third sub-pixel 13 is provided with the cut edge 15, the center of gravity of the third sub-pixel 13 is shifted in a direction close to the other side opposite to the cut edge 15. For ease of description, the side opposite and furthest from the trim 15 will be referred to herein as the opposite side 16 of the trim 15. As shown in fig. 3, this means that the center of gravity of the third sub-pixel 13 is shifted toward the opposite side 16 side of the cut edge 15 so that the center of gravity of the third sub-pixel 13 does not overlap with the vertex of the second virtual rectangle 22. Note that, the original center of the third sub-pixel 13 provided with the trimming 15 (i.e., the center of the sub-pixel before the trimming 15 is not provided) overlaps with the vertex of the second virtual rectangle 22, thereby reducing the influence of the trimming 15 on the arrangement of the third sub-pixel 13.

By the arrangement, the risk of scratching the support column 14 can be reduced without reducing the resolution.

As shown in fig. 5, in one embodiment, one of the two first sub-pixels 11 is provided with a trimming 15, the centers of the two second sub-pixels 12 are located at the vertex of the first virtual rectangle 21, the centers of the four third sub-pixels 13 are located at the vertex of the second virtual rectangle 22, the center of gravity of the first sub-pixel 11 provided with the trimming 15 is not overlapped with the vertex of the first virtual rectangle 21, and the center of the other first sub-pixel 11 is overlapped with the vertex of the first virtual rectangle 21.

The first sub-pixel 11 is provided with a cut-out 15 and the support column 14 is located between the adjacent first sub-pixel 11 and second sub-pixel 12 provided with a cut-out 15. By providing the cut edges 15, the placing space of the support column 14 is increased, and the risk that the support column 14 is scratched by the opening of the photomask is reduced. Since the first sub-pixel 11 is provided with the cut edge 15, the center of gravity of the first sub-pixel 11 is offset toward the opposite side 16 side of the cut edge 15, and therefore, the center of gravity of the first sub-pixel 11 does not overlap with the vertex of the first virtual rectangle 21. Note that, the original center of the first sub-pixel 11 provided with the trimming 15 (i.e., the center of the sub-pixel before the trimming 15 is not provided) overlaps with the vertex of the first virtual rectangle 21, thereby reducing the influence of the trimming 15 on the arrangement of the first sub-pixel 11.

As shown in fig. 6, in one embodiment, one of the two second sub-pixels 12 is provided with a trimming 15, the centers of the two first sub-pixels 11 are located at the vertex of the first virtual rectangle 21, the centers of the four third sub-pixels 13 are located at the vertex of the second virtual rectangle 22, the center of gravity of the second sub-pixel 12 provided with the trimming 15 is not overlapped with the vertex of the first virtual rectangle 21, and the center of the other second sub-pixel 12 is overlapped with the vertex of the first virtual rectangle 21.

The second sub-pixel 12 is provided with a cut-out 15 and the support column 14 is located between the adjacent second sub-pixel 12 and first sub-pixel 11 provided with a cut-out 15. By providing the cut edges 15, the placing space of the support column 14 is increased, and the risk that the support column 14 is scratched by the opening of the photomask is reduced. Since the second sub-pixel 12 is provided with the cut edge 15, the center of gravity of the second sub-pixel 12 is offset toward the opposite side 16 side of the cut edge 15, and therefore, the center of gravity of the second sub-pixel 12 does not overlap with the vertex of the first virtual rectangle 21. Note that, the original center of the second sub-pixel 12 provided with the trimming 15 (i.e., the center of the sub-pixel before the trimming 15 is not provided) overlaps with the vertex of the first virtual rectangle 21, thereby reducing the influence of the trimming 15 on the arrangement of the second sub-pixel 12.

In one embodiment, as shown in fig. 3 to 6, in one repeating unit 10, the center of one third sub-pixel 13 overlaps the center of the first virtual rectangle 21. In fig. 3, when the third subpixel 13 located in the first virtual rectangle 21 is not provided with the trimming 15, the center of the third subpixel 13 overlaps the center of the first virtual rectangle 21. When the third sub-pixel 13 located within the first virtual rectangle 21 is provided with the cut edge 15, the center of gravity of the third sub-pixel 13 provided with the cut edge 15 does not overlap with the center of the first virtual rectangle 21.

In an embodiment, in one repeating unit 10, when the second sub-pixel 12 or the first sub-pixel 11 is a sub-pixel provided with a cut edge 15, the center of the third sub-pixel 13 located within the first virtual rectangle 21 overlaps the center of the first virtual rectangle 21.

As shown in fig. 3 to 6, in an embodiment, the first sub-pixel 11 without the trimming 15, the second sub-pixel 12 without the trimming 15, and the third sub-pixel 13 without the trimming 15 are axisymmetric. Through the arrangement, the display panel can be symmetrical in all directions of the display plane when displaying pictures, so that the display effect is improved.

As shown in fig. 7, (a), (b), and (c) are patterns of the first, second, and third sub-pixels 11, 12, and 13, respectively, and (e), (f), and (g) are patterns of the first, second, and third sub-pixels 11, 12, and 13, respectively, after trimming 15 is provided. It should be noted that fig. 7 illustrates a pattern of sub-pixels, and should not be construed as limiting the pattern of sub-pixels of the present application. In an embodiment, the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are octagonal, the cut edge 15 is perpendicular to the first side 211 of the first virtual rectangle 21, and two opposite sides of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are parallel, that is to say, the cut edge 15 is parallel to the opposite side 16 of the cut edge 15, and the adjacent side 18 of the cut edge 15 is parallel to the opposite side 18 of the adjacent side 18. In either sub-pixel where the trim 15 is disposed, the trim 15 is parallel to the opposite edge 16 of the trim 15, and the length of the trim 15 is greater than the length of the opposite edge 16 of the trim 15, and the length of the adjacent edge 18 of the trim 15 is less than the length of the opposite edge 19 of the adjacent edge 18.

Through the above arrangement, the embodiment can ensure that the viewing angles in all directions of the display plane are symmetrical, so that the display effect is improved, and the risk of scratching the support column 14 can be reduced without reducing the resolution. Further, the light emitting area of the sub-pixel provided with the trimming 15 can be ensured, and the influence of the trimming 15 on the display effect can be reduced.

As shown in fig. 7, in an embodiment, the first sub-pixel 11 is a blue sub-pixel, the second sub-pixel 12 is a red sub-pixel, the third sub-pixel 13 is a green sub-pixel, the area of the first sub-pixel 11 is larger than the area of the second sub-pixel 12, and the area of the second sub-pixel 12 is larger than the area of the third sub-pixel 13. Since the light emission lifetime of the green sub-pixel is longer than that of the red sub-pixel, and the light emission lifetime of the red sub-pixel is longer than that of the blue sub-pixel, the light emission lifetime is positively correlated with the area of the sub-pixel. Therefore, the embodiment can make the light emitting life of the sub-pixels of each color close by the above arrangement, and can improve the resolution of the display panel.

As shown in fig. 3 to 6, in one embodiment, the center of the support column 14 is located on one side of the first virtual rectangle 21 or the second virtual rectangle 22 near the cut edge 15 at the midpoint thereof. By the arrangement, the distance between the support column 14 and the adjacent two sub-pixels is similar, and the risk that the support column 14 is scratched by the opening of the photomask corresponding to any adjacent sub-pixel is further reduced. Still further, as shown in FIG. 4, in one embodiment, the center of the support column 14 may be disposed at the midpoint of the second spacing. The arrangement of the support column 14 when it is between the other two sub-pixels is similar and will not be repeated here.

It should be understood that fig. 3 to 6 only show one arrangement of the repeating units 10, and the arrangement of the repeating units 10 obtained by rotation, mirroring or the like is also included in the scope of protection of the present application. Similarly, fig. 3 to 6 show only one arrangement of the trimming 15, and it should be noted that the trimming 15 may be disposed on any side of the first virtual rectangle 21 or the second virtual rectangle 22, and the support columns 14 may be disposed corresponding to the trimming 15.

In this embodiment, the display terminal may be: any product or component with display function such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like.
